Description

1 DESCRIPTION Title of the Invention: BOTTLE CONTAINER Technical Field [0001] The present invention relates to a bottle container. Background Art [0002] In the past, a bottle container made of a synthetic resin has been widely used as a container for a liquid material, such as liquid detergent, liquid softener, or liquid bleach. When a conventional bottle container contains contents having gas absorbability, pressure in the container is reduced by the reduction of gas present in a head space. Accordingly, the deformation of the container may occur. Gas present in a head space, which is a space remaining at an upper portion of the container, is absorbed, so that pressure in a head space is reduced to pressure lower than atmospheric pressure. Accordingly, unintended dents or deformation occurs on the container. In particular, when a spout is provided so as to be fitted to an open neck portion and the spout includes a spout container having a bulging shape at a fitted portion or near the fitted portion or a shoulder portion of a body portion of the container or the vicinity of the shoulder portion has a wide shape, the amount of absorbed gas present in the head space is large. When these dents or the like are formed on a container of a commercial product that is displayed in a store, the image of the commercial product deteriorates. This problem can also be generated when high-temperature liquid is cooled after the high-temperature liquid is injected into the container and the container is hermetically sealed, other than when contents has gas absorbability. [0003] There is proposed a technique for solving a problem of deformation, which is caused by the reduction of the internal pressure of the bottle container, by changing the 2 curvature of the surface side of the horizontal section of the body portion and the curvature of the back side thereof and by intentionally providing a surface deformed so as to correspond to the reduction in pressure (Patent Literature 1). Further, there is also provided a technique for specifying a portion to be deformed and suppressing the deterioration of appearance as much as possible by forming a dent guide line on at least one of side walls, which form the front surface and the rear surface of a body portion of a bottle container, and making the body portion have a shape in which a diameter is gradually reduced toward the dent guide line from a bottom portion and a shoulder portion (Patent Literature 2). Citation List Patent Literature [0004] [Patent Literature 1] JP 2001-199419 A [Patent Literature 2] JP 2009-132436 A [Patent Literature 3] JP 2002-362525 A Summary of Invention [0005] Since the change of the curvature of the surface side and the curvature of the back side is essential in the technique of Patent Literature 1, the technique of Patent Literature 1 cannot be applied to a container of which the shape of the surface side and the shape of the back side are symmetrical to each other, that is, the technique of Patent Literature 1 has a limitation on the shape of the container. Patent Literature 1 discloses that a lateral band-shaped rib is provided, but the lateral band-shaped rib is formed on the back side that is easily deformed with a small curvature. In the technique of Patent Literature 2, a label is deformed so as to be distorted at the position of the dent guide line when the label is attached so as to cover the dent guide line, and a range in which a label can be attached is limited when the label is attached not to overlap the dent guide line. Moreover, the dent guide line of Patent Literature 2 is not a recessed rib.

3 [0006] Further, Patent Literature 3 discloses a technique for providing ribs on a squeeze container. However, since the ribs are provided to improve the fracture strength of the container, the ribs are formed on a pair of surfaces, which face each other, of a body portion of the container. [0007] The invention provides a bottle container that can solve the above-mentioned problems of the techniques in the related art. [0008] The present invention relates a bottle container including an open neck portion that includes an opening, and a container body that includes a bottom portion and a body portion and is made of a synthetic resin, the open neck portion being provided at an upper portion of the bottle container and the bottom portion being provided at a lower portion of the bottle container, the bottle container including a cap that is mounted on the open neck portion. The cap includes a tube portion that hangs down to a lower portion of the open neck portion through the open neck portion when the cap is mounted on the open neck portion. A horizontal section of the body portion has a flat shape that has a major axis direction and a minor axis direction. The body portion includes a shoulder portion that is formed to descend while horizontally expanding from a lower end of the open neck portion; a front wall and a rear wall inner surfaces of which face each other in the minor axis direction; a pair of side walls that are positioned at both ends of the body portion in the major axis direction; and a handle that is formed closer to one side wall in the major axis direction and extends from the shoulder portion to the lower portion of the bottle. A recessed groove is formed only on the front wall. A label is attached to the front wall so as to cover the recessed groove.

Description of Embodiments [0010] The invention will be described below on the basis of preferred embodiments thereof. As illustrated in Figs. 1(a) to 1(c), a bottle container 1 (hereinafter, simply referred to as a container 1) according to a first embodiment of the invention includes an open neck portion 3 that includes an opening 31 and a container body 2 that includes a bottom portion 4 and a body portion 5. The container body 2 includes the open neck portion 3 on an upper side thereof and includes the bottom portion 4 on a lower side thereof. The open neck portion 3 includes the opening at an upper end thereof. The open neck portion 3 is formed in a cylindrical shape, and includes the opening 31 at the upper end thereof. A cap is mounted on the open neck portion 3, and can hermetically seal the inside of the container body 2. The structure of the cap, which is mounted on the open neck portion 3, is not particularly limited, and examples of the cap include a cap illustrated in Figs. 1(a) to 1(c) that includes a spout cap 80 including a spout tube 82 and a measuring cap 86 screwed to the spout cap 80. The bottom portion 4 is formed so as to allow the bottle container 1 to independently stand on a horizontal surface. In this specification, the upper side is an upper side in a vertical direction when the bottle container is allowed to independently stand on a horizontal surface so that the bottom portion of the container body is installed on the horizontal surface, and the lower side is a lower side in a vertical direction when the bottle container is allowed to independently stand on a horizontal surface so that the bottom portion of the container body is installed on the horizontal surface.

6 [0011] The body portion 5 is positioned between the open neck portion 3 and the bottom portion 4 in the height direction of the container body 2. As illustrated in Fig. 2, the horizontal section of the body portion 5 has a flat shape that has a major axis direction X and a minor axis direction Y. The body portion 5 includes a shoulder portion 50 that is formed to descend while horizontally expanding from the lower end of the open neck portion 3, front and rear walls 51 and 52 of which inner surfaces a face each other, a pair of side walls (a first side wall 53 and a second side wall 54) that are positioned at both ends of the body portion in the major axis direction X, and a handle 7 that is formed close to the second side wall 54 (one side wall) in the major axis direction X so as to extend from the shoulder portion 50 over the lower portion of the bottle. Further, horizontal recessed grooves 6 (recessed ribs) formed of recessed grooves are formed on the front wall 51. The first and second side walls 53 and 54 are formed between the front and rear walls 51 and 52 in the circumferential direction of the body portion 5. Boundary surfaces between the front wall 51 and rear wall 52 and the first wall 53 and the second side wall 54 may be smoothly connected, or may be connected through boundary surfaces having a large curvature. Furthermore, the boundary surfaces may be connected through ridgelines 56 and 57 illustrated in Figs. 1(a) to 1(c). The handle 7, which is used to hold the container by being held by a hand, is formed at the container 1 of this embodiment as described above, and a through hole (holding space) 71 for forming the handle 7 is formed in the body portion 5. The through hole (holding space) 71 for forming the handle 7 is such a manner the front wall 51and the rear wall 52 are connected to each other by cylindrical walls 55 which pass through the body portion 5. [0012] As illustrated in Fig. 2, the body portion 5 has a flat shape in which a distance Li between the front wall 51 and the rear wall 52 (a distance between outer surfaces b) is smaller than a distance L2 between the left side wall 53 and the right side wall 54 in the direction X orthogonal to the direction Y in which the front and rear walls 51 and 52 face each other. In order to say that the body portion 5 has a flat shape, a distance between a pair of side walls may be longer than a distance between the front and rear walls 51 and 52 at a middle height position C7 of the through hole 71 for forming the 7 handle in the height direction. Hereinafter, the major axis direction X orthogonal to the direction (minor axis direction) Y in which the front and rear walls 51 and 52 face each other is also referred to as a width direction X. Fig. 2 illustrates a horizontal section of the body portion 5 taken at a height position P where a height T between the bottom portion 4 and the open neck portion 3 is divided into two equal pieces, but whether or not the distance Li is smaller than the distance L2 is determined at the middle height position C7 of the through hole 71 for forming the handle 7 in the height direction. [0013] The handle 7 is formed at the body portion 5 so as to extend from the shoulder portion, which is formed around the open neck portion 3, over the lower portion of the bottle. Further, the body portion 5 and the handle 7 are connected to each other with the through hole (holding space) 71 for forming the handle interposed therebetween. It is preferable that the handle 7 have stiffness so as to allow the bottle to be held, and the fact that the body portion 5 includes the handle 7 causes a problem in that the front wall and the rear wall of the bottle container are easily deformed. That is, since the body portion includes the handle, the front wall and the rear wall are likely to become thin and an effect of the invention is obtained. The lower portion of the bottle is a range that extends from the middle portion of the body portion 5 over the bottom portion in the height direction. Each of container bodies of bottle containers illustrated in Figs. 16(a) and 16(b) includes a handle 7 that is formed so as to extend from a shoulder portion of a body portion 5 to the lower portion of the bottle. As described above, "so as to extend from the shoulder portion to the lower portion of the bottle" in the invention includes an embodiment that includes the handle extending from the shoulder portion toward the lower portion of the bottle. The handle 7 is hollow, and is adapted so that a part of contents contained in the bottle container 1 enters the handle 7. [0014] The distance Li between the outer surfaces b of the front wall 51 and the rear wall 52 is preferably 80% or less of the distance L2 between the left side wall 53 and the right side wall 54 and more preferably 70% or less thereof, and is preferably 50% or 8 more thereof and more preferably 60% or more thereof. The distances Li and L2 are measured at the middle height position C7 of the through hole 71 for forming the handle 7 in the height direction. In the height direction, the amount of a resin corresponding to other portions of the body portion 5 is reduced since the handle 7 (grip) having strength is formed in the region of the body portion 5 that includes the through hole 71 for forming the handle, and the reduction in the amount of a resin corresponding to other portions causes the front and rear walls 51 and 52 to be easily deformed. Accordingly, it is reasonable that the distances Li and L2 should be measured at the middle height position C7 of the through hole 71 in the height direction. [0015] The body portion 5 of this embodiment will be described in more detail. Each of the front wall 51 and the rear wall 52 includes a first ridgeline 56 between the first side wall 53 and the front wall 51 or the rear wall 52, and includes a second ridgeline 57 at a connecting portion formed between the cylindrical wall 55, which forms the through hole (holding space) 71 forming the handle 7 and passes through the body portion 5, and the front wall 51 or the rear wall 52. The second ridgeline 57 surrounds the through hole (holding space) 71 in the front view of the bottle container 1, as illustrated in Fig. 1(b), and extends over the lower portion of the second side wall 54 as illustrated in Fig. 1(c). Since the first ridgeline 56 and the second ridgeline 57 are provided, deformation caused by the reduction of pressure in the bottle is prevented and deformation does not easily stand out when the rear wall 52 is deformed. Further, the body portion 5 includes the shoulder portion 50 that is formed at the upper portion thereof and descends while horizontally expanding from the lower end of the open neck portion 3, and an upper ridgeline 58 is formed at a boundary between the front wall 51 and the shoulder portion 50 and at a boundary between the rear wall 52 and the shoulder portion 50. As illustrated in Fig. 1(b), the upper ridgeline 58 extends , in the upper portion of the body portion 5, obliquely from the first side wall 53 toward the second side wall 54, and the first ridgeline 56 is connected to the upper ridgeline 58 in the upper portion of the body portion 5. Furthermore, as illustrated in Fig. 1(c), the upper ridgeline 58 continues over the upper portion of the front wall 51, the upper portion of the second side wall 54, and the upper portion of the rear wall 52. Moreover, a stepped portion 59 is formed in the lower portion of each of the 9 front and rear walls 51 and 52. The outer surface b of each of the front and rear walls 51 and 52 protrudes outside of the container 1 in the vicinity of the bottom portion 4, so that the stepped portion 59 is formed. The first side wall 53 and the shoulder portion 50 are connected to each other by a convexly curved surface with no ridgeline interposed therebetween. [0016] Substantially the entire area of each of the front and rear walls 51 and 52, which is surrounded by the first ridgeline 56, the second ridgeline 57, the upper ridgeline 58, and the stepped portion 59, forms a label-attachment surface 9 to which a label is to be attached. In Fig. 1(b), the shape of the label, which is to be attached to the label-attachment surface 9, and the position where the label is to be attached are denoted by reference numeral 10A. [0017] In this embodiment, as illustrated in Fig. 2, the horizontal section of a label-attachment surface 91 formed on the front wall 51 is curved in the shape of a circular arc that is convex toward the outside of the container. Likewise, the horizontal section of a label-attachment surface 92 formed on the rear wall 52 is also curved in the shape of a circular arc that is convex toward the outside of the container. The radius of curvature of the horizontal section of the label-attachment surface 9 is preferably R40 cm or more and more preferably R100 cm or more in terms of an increase in the size of an attachable label and the improvement of the visibility of the display of an attached label. The upper limit of the radius of curvature of the horizontal section of the label-attachment surface 9 is preferably 500 cm or less and more preferably 300 cm or less. R means the radius of curvature of the horizontal section. [0018] As an area Si, which is occupied by the label, is large with respect to an area S2 of the label-attachment surface of the front wall of the bottle container, the invention is more effective. A percentage [(S 1/S2) x 100] of the label is preferably in the range of 70 to 90% and more preferably 70 to 80%.

10 The percentage of the label is a ratio of the area S 1 of the label, which is attached to the label-attachment surface of the front wall, to the area S2 of the label-attachment surface. [0019] Here, the front and rear walls 51 and 52 are formed of quadric surfaces formed on the surface of the bottle except for a handle in a flat bottle including the handle in a cross-section, which is formed by front and rear quadric surfaces (each of which the label surface of the horizontal section has a radius of curvature in the range of R40 to R500) and side surfaces, and are surfaces adjacent to a surface including the handle. Further, when the bottle container is developed on a plane, the front and rear walls 51 and 52 are formed of quadric surfaces (each of which the label surface of the horizontal section has a radius of curvature in the range of R40 to R500) and are surfaces adjacent to a surface including the handle. [0020] Furthermore, the label-attachment surface 91 of this embodiment is curved so as to be convex toward the outside of the container in the horizontal cross-section, and has a linear shape in a cross-section taken along a height direction (vertical direction). That is, the label-attachment surface 91 is formed of a quadric surface. The "quadric surface" mentioned in this specification is a curved surface of which only one of two axes orthogonal to each other is curved. Likewise, the label-attachment surface 92 of the rear wall 52 is also curved so as to be convex toward the outside of the container in the horizontal cross-section, and has a linear shape in a cross-section taken along a height direction (vertical direction). That is, the label-attachment surface 92 is also formed of a quadric surface. In terms of neatly attaching a general label that lacks in elongation, it is preferable that each of the label-attachment surfaces 91 and 92 be a quadric surface. [0021] Meanwhile, the curvature of the first and second side walls 53 and 54 is larger than the curvature of the label-attachment surfaces 91 and 92 in the horizontal cross-section.

11 [0022] In the container 1 of this embodiment, the recessed grooves 6 are formed on the label-attachment surface 91 of the front wall 51 of the body portion 5 to suppress the deformation of the front wall 51 that is caused by the reduction of pressure in the container. The recessed grooves 6 of this embodiment are recessed grooves that are formed by denting the outer surface b of the front wall 51 in the shape of a groove, and the plurality of recessed grooves 6 are formed at intervals in the height direction of the container body 2. As illustrated in Fig. 1(b), each of the recessed grooves 6 is a horizontal groove extending in a horizontal direction and the plurality of recessed grooves 6 are formed parallel to each other. The depth d of the recessed groove 6 may be constant over the entire length of the recessed groove 6 in a longitudinal direction, or the depth d of the recessed groove may be gradually reduced toward both end portions of the recessed groove from the vicinity of the middle portion of the recessed groove in the longitudinal direction. Further, when the depth of the groove is gradually reduced toward both end portions of the recessed groove 6, the bottom of the recessed groove may be flush with the outer surface b of the other portion at both end portions of the recessed groove. [0023] In terms of the suppression of the deformation of the front wall 51 that is caused by the reduction of pressure in the container, or the like, it is preferable that the recessed grooves 6 formed on the front wall satisfy one or two or more of the following conditions. The same applies to inclined recessed grooves 6A and 6B or small recessed grooves 61 of intermittent recessed grooves that will be described below. The depth d of the deepest portion of a recessed groove which is provided as the recessed groove 6 is preferably 1 mm or more, is preferably 10 mm or less and more preferably 5 mm or less, and is preferably in the range of 1 mm to 10 mm and more preferably in the range of 1 mm to 5 mm. Further, the width W of the recessed groove 6 is preferably 50% or more of the depth d and more preferably 100% or more thereof, is preferably 200% or less thereof and more preferably 160% or less thereof, and is preferably in the range of 50% to 200% thereof and more preferably in the range of 100% to 160% thereof.

12 [0024] Furthermore, the width W of the recessed groove 6 is preferably 2 mm or more and more preferably 3 mm or more, is preferably 10 mm or less and more preferably 5 mm or less, and is preferably in the range of 2 mm to 10 mm and more preferably in the range of 3 mm to 5 mm. Moreover, the length of the recessed groove 6 is preferably 10% or more of the distance L2 and more preferably 20% or more thereof. It is preferable that a total length of small recessed grooves of intermittent recessed grooves (6', 6A', and 6B') to be described below be in this range. It is preferable that the length of the recessed groove 6 be in the range of 40% to 70% of the width L3 of the container except for the handle. The width L3 of the container except for the handle is measured at the position P where the height, between the bottom portion 4 and the open neck portion 3, of the container is divided into halves. Further, at least one recessed groove 6 (recessed groove) can be formed in middle three regions when the body portion 5 is divided into five equal regions by four horizontal planes in the height direction so that the height T between the bottom portion 4 and the open neck portion 3 is divided into five equal pieces. Furthermore, the recessed grooves 6 (ribs) can be positioned so as to be concentrated on the bottom portion. For example, the horizontal recessed grooves 6 (ribs) can be positioned so as not to be present in the uppermost one region when the body portion 5 is divided into five equal regions by four horizontal planes in the height direction so that the height T between the bottom portion 4 and the open neck portion 3 is divided into five equal pieces. [0025] Moreover, the recessed groove 6 (recessed groove) may have a U-shaped cross-section that includes a bottom surface and upper and lower surface positioned on the upper and lower sides of the bottom surface with the bottom surface interposed between the bottom surface and upper and lower surface, as illustrated in Fig. 3, and may have a circular arc-shaped cross-section or a V-shaped cross-section as illustrated in Figs. 9(c) and 9(d). However, in terms of the suppression of deformation that is caused by the reduction of pressure in the container, or the like, it is preferable that the recessed groove have a circular arc-shaped cross-section.

13 [0026] Further, a total length of the recessed grooves 6 formed on the front wall 51 is preferably 1.5 times or more of the width L4 of the container and more preferably 2 times or more thereof. The width L4 of the container is a distance L2 between the left and right side walls 53 and 54 at the height position P where the height T between the bottom portion 4 and the open neck portion 3 is divided into two equal pieces. [0027] In the invention, it is preferable that the recessed grooves formed on the front wall 51 extend in a direction crossing a height-direction line L3 of the container body 2. Crossing the height direction line L3 means that an inclination angle 0 with respect to the height-direction line L3 is in the range of 200 to 900 and more preferably in the range of 450 to 900. The height-direction line L3 is a straight line perpendicular to the bottom portion 4 in the front view [see Fig. 1(b)] of the container body, and the inclination angle 0 is also measured in the front view of the container body as illustrated in Figs. 5(b) and 6(b). [0028] It is further preferable that the recessed groove formed on the front wall 51 be a horizontal recessed groove extending in the circumferential direction of the body portion like the recessed groove 6 of this embodiment. An inclination angle 0 between the horizontal recessed groove and the above-mentioned height-direction line L3 is in the range of 600 to 900 (an inclination angle between the horizontal recessed groove and the horizontal plane is in the range of 0 to 300). It is further preferable that the inclination angle 0 between the height-direction line L3 and the horizontal recessed groove be in the range of 700 to 900 (the inclination angle between the horizontal plane and the horizontal recessed groove be in the range of 0 to 200). The inclination angle between the horizontal plane and the horizontal recessed groove illustrated in Figs. 1(a) to 1(c) is 50 or less and more specifically 00. [0029] In the container 1 of this embodiment, the rear wall 52 is made to be more 14 easily deformed than the front wall 51, and recessed grooves (recessed ribs), such as the horizontal recessed grooves 6 formed on the front wall 51, are not formed on the rear wall 52 so that deformation caused by the reduction of pressure in the container is concentrated on the rear wall 52 of the body portion 5. Meanwhile, the body portion 5 and the bottom portion 4 of the container 1 of this embodiment have a shape symmetrical with respect to a virtual plane S positioned between the front and rear walls 51 and 52 except that the horizontal recessed grooves 6 are formed on the front wall 51 and recessed groove such as the horizontal recessed grooves 6 are not formed on the rear wall 52. [0030] The bottle container 1 of this embodiment is used while a label is attached to at least the label-attachment surface 91 of the front wall 51 on which the horizontal recessed grooves 6 (ribs) are formed. Further, it is preferable that a label be also attached to the label-attachment surface 92 of the rear wall 52. However, a label may not be attached to the label-attachment surface 92 of the rear wall 52. The front and rear walls 51 and 52, particularly, the label-attachment surfaces 91 and 92 of the front and rear walls 51 and 52 have the largest area on the body portion 5, and it is preferable that labels displaying a trade name, explanation for contents, and the like be attached to these surfaces in terms of visibility or the like. Here, when contents has gas absorbability, or when high-temperature liquid is cooled after the high-temperature liquid is injected into the bottle container and the bottle container is hermetically sealed, pressure in the container is further reduced than the pressure of outside air and deformation is likely to occur. In this regard, since the horizontal recessed grooves 6 (recessed ribs) are formed on the front wall 51 of the bottle container 1 of this embodiment, the deformation of the front wall 51 caused by the reduction of pressure in the container hardly occurs. Moreover, since ribs such as the horizontal recessed grooves 6 are not formed on the rear wall 52 so that the rear wall 52 is more easily deformed than the front wall 51, deformation caused by the reduction of pressure in the container is generated so as to be concentrated on the rear wall 52. Accordingly, the deformation of the front wall 51 is further suppressed. The thickness of the container has been increased or protruding ribs have been formed on both the front and rear walls to improve stiffness, but the reduction of pressure in the container is not cancelled in this 15 case. Since this technique allows the rear wall 52 to be more easily deformed than the front wall 51, the container can maintain a stable shape even though pressure in the container is reduced. For this reason, when the bottle container 1 containing contents is displayed on a display stand in a store, such as a supermarket, a convenience store, or a department store, so that a label attached to the front wall 51 which is hardly deformed faces the front side of the stand and the rear wall 52 faces the rear side of the stand, the appearance of the bottle container seen from a visitor (a customer or a person intending to purchase items) can be neatly kept for a long time. [0031] Meanwhile, when labels are attached to both the front and rear walls 51 and 52 of the body portion, it is preferable that the label attached to the front wall which is hardly deformed be a label on which the largest trade name is displayed and the label attached to the rear wall easily deformed be a sub-label on which ingredients less important in design are displayed. [0032] Shrink labels can be used on the front and rear walls 51 and 52 of the body portion. In particular, since wrinkles are generated on the surface of a thin shrink label due to the deformation of the container, the display performance of the thin shrink label deteriorates. It is possible to prevent the deformation of a surface, which is to be displayed using a shrink label, by this technique. [0033] In the bottle container 1 of this embodiment, a cap 8, which includes two members, that is, the spout cap 80 and the measuring cap 86, is mounted on the open neck portion 3 of the container body 2. Fig. 1(b) illustrates a state in which the cap 8 is detached from the open neck portion 3, but a part E of the cap 8 is inserted into the body portion 5 of the container body in a state in which the cap 8 is mounted on the open neck portion 3 (mounting state). The cap 8 includes the spout cap 80 that is fitted to the open neck portion 3 and the measuring cap 86 that is fixed so as to cover the spout tube 82 (spout) of the spout 16 cap 80, and the spout cap 80 includes the spout tube 82, and an outer tube 83 that is separated from the spout tube 82. As illustrated in Fig. 4, the spout cap 80 includes a connection skirt portion 81 that is connected to the container body 2, the spout tube 82, and the outer tube 83 that surrounds the spout tube. The connection skirt portion 81 is formed so as to hang down from an outer peripheral portion of an annular protrusion, which protrudes outward from the middle portion of the outer tube 83 in a height direction, and the connection skirt portion 81 is fixed to the container body 2, which is filled with contents, by being mounted on the open neck portion 3 by a known method such as fitting or screwing. The spout cap 80 includes the spout tube 82 that protrudes upward from a partition plate 84 and the outer tube 83 that is connected to the spout tube 82 via the partition plate 84, a recessed liquid recovery space 85 is formed between the spout tube 82 and the outer tube 83, and a liquid recovery opening 84a is formed at the bottom portion of the liquid recovery space 85. Further, a cut-off portion (spout cutout) 82a, which reaches the liquid recovery opening 84a from an upper end portion of the spout tube 82 in an axial direction, is formed at the spout tube 82. Since the outer tube 83 includes a thread 83a formed on the outer surface thereof, the measuring cap 86 can be detachably screwed to the outer tube 83. [0034] When the spout cap 80 is fixed to the open neck portion 3 of the container body 2, the lower end portion of the outer tube 83 connected to the partition plate 84 forming the bottom portion of the liquid recovery space 85 and the vicinity thereof extend further downward than the lower end of the connection skirt portion 81, and the lower end portion of the outer tube 83 and the vicinity E thereof, which extend further downward than the lower end of the connection skirt portion 81, are inserted into the body portion 5 of the container body 2. The outer tube 83 of the spout cap 80 is a tube portion that hangs down to the lower portion of the open neck portion through the open neck portion. It is preferable that a portion hanging down to the lower portion of the open neck portion through the open neck portion reach the position of the lower end of the open neck portion, that is, a boundary portion between the open neck portion and the body portion, and it is more preferable that the portion reach the lower side of the position of the lower end of the open neck portion and reach the inside of the body 17 portion 5. [0035] When contents is contained in the bottle container 1, it is preferable that the amount of contents be suppressed to an amount where the level of the contents does not come into contact with the part E of the spout cap 80 inserted into the body portion 5. However, since the shoulder portion 50 forming the upper portion of the body portion 5 is a portion of which the horizontal sectional area is suddenly increased in comparison with the horizontal sectional area of the open neck portion 3, the volume of a head space remaining above the level of the contents is suddenly increased when the amount of liquid is set so that the level of the liquid is positioned below the lower end of the open neck portion 3. According to the bottle container 1 of this embodiment, the volume of the head space is increased as described above. Accordingly, gas is absorbed in the contents having gas absorbability, so that the dent or deformation of the body portion is likely to be increased. For this reason, there is a large merit in suppressing the deformation of the front wall 51 by forming recessed grooves such as the horizontal recessed grooves 6 only on the front wall 51 so that deformation caused by the reduction of pressure in the bottle container is concentrated on the rear wall 52. [0036] In order to prevent the level of the contents from coming into contact with the lower end portion of the open neck portion or the part E of the spout cap 80 inserted into the body portion, for example, the level of the liquid contents, before the cap is opened, is separated from the lower end of the open neck portion in the height direction by a distance of 10 mm or more, preferably 30 mm or more, and more preferably 50 mm or more. [0037] To pour out contents from the bottle container 1 through the spout cap 80, it is necessary to tilt the container body 2 after the measuring cap 86 is removed. Accordingly, contents flows out of a spout portion P2 that is a portion of the spout tube 82 facing the cut-off portion 82a in the circumferential direction. When the spout cap 18 80 is fixed to the container body 2, the spout cap 80 is fixed so that the cut-off portion 82a (spout cutout) faces the handle 7. That is, the cut-off portion 82a (the spout cutout of the spout tube) is positioned and fixed so as to face the handle 7, that is, the second side wall 54. [0038] Contents contained in the bottle container of the invention is preferably liquid contents, and examples of the contents include liquid detergent, liquid softener, liquid bleach, shampoo, rinse, and liquid food. However, the contents is not limited thereto. When liquid having gas absorbability is used as the contents, an advantage obtained from the use of the bottle container of the invention is further large. Examples of the liquid having high gas absorbability include a liquid detergent that contains a surfactant in a high concentration. One or more of surfactants selected from an anionic surfactant, a non-ionic surfactant, a cationic surfactant, and an amphoteric surfactant can be used as the surfactant contained in the contents, but a non-ionic surfactant is more preferable as the surfactant. In regard to the kind of the surfactant, an effect of the invention is further recognized when contents containing a surfactant, which has an ethylene oxide group or an ethylene oxide group/a propylene oxide group in molecules, is contained in the bottle container. When contents containing a non-ionic surfactant or an anionic surfactant such as polyoxyethylene (average addition mole number of 1 to 10 moles) alkyl ether sulfate ester salt or polyoxyethylene (average addition mole number of 1 to 10) alkyl ether acetate among them is contained in the bottle container, an effect of the invention is further recognized. [0039] Examples of a typical non-ionic surfactant may include alkyl polyglyceryl ether (having an average addition mole number of 1 to 10) and alkyl polyglycoside (having an average addition mole number of 1 to 10) having an alkenyl group or an alkyl group having a carbon number of 8 to 18. [0040] Examples of a typical cationic surfactant include dialkyldimethylammonium 19 salt, monoalkyldimethylbenzyl ammonium salt, and monoalkyl trimethyl ammonium salt having an alkenyl group or an alkyl group having a carbon number of 8 to 18. [0041] Examples of a typical amphoteric surfactant include alkylsulfo betaine, alkyl hydroxy sulfobetaine, alkyl amide propyl carboxy betaine, alkyl amide dimethylamine oxide, and alkyl dimethyl amine oxide having an alkenyl group or an alkyl group having a carbon number of 8 to 18. Further, examples of absorbent gas may include oxygen. The mass of a high-concentration surfactant is 3 mass% or more in a total amount of the liquid detergent, and is preferably 15 mass% or more therein and more preferably 50 mass% or more therein. Furthermore, the mass of an additive is 0.3 mass% or more, preferably 0.5 mass% or more, and more preferably 0.7 mass% or more. The liquid detergent may contain a solvent, and the total mass of the surfactant and the solvent is preferably 20 mass% or more, more preferably 30 mass% or more, and much more preferably 70 mass% or more. A non-ionic surfactant is preferable as the surfactant, and a perfume is preferable as the additive. [0042] Further, when the bottle container of the invention is a relatively large container of which the amount of contents is large, an effect of the invention is further significant. The mass of contents contained in the bottle container is preferably 0.95 kg or more, more preferably 1.5 kg or more, and much more preferably 2.0 kg or more. The internal volume of the container body of the bottle container is preferably 300 cm 3 or more and more preferably 1000 cm 3 or more, is preferably 5000 cm 3 or less and more preferably 4000 cm 3 or less, and is preferably in the range of 300 cm 3 to 5000 cm 3 and more preferably in the range of 1000 cm 3 to 4000 cm 3 . Meanwhile, the internal volume of the container body is the volume of an inner space of a portion of the container body that is present below the open neck portion. [0043] Further, the volume of a head space (that is, a space remaining at an upper 20 portion of the container), which is obtained by the subtraction of the volume of contents from the internal volume of the container body of the bottle container, is 150 cm 3 or more, preferably 250 cm3 or more, and more preferably 300 cm3 or more. [0044] Furthermore, when the amount of a resin used to form the bottle container of the invention is small and the thickness of the body portion is thin, an effect of the invention is further significant. The mass of the container body per an internal volume of 100 cm 3 is more preferably 7 g or less and much more preferably 5 g or less, and is preferably 3 g or more and more preferably 4 g or more. [0045] Further, the thickness of the bottle container is preferably in the range of 0.3 to 3 mm and more preferably in the range of 0.3 to 1.2 mm. It is preferable that the number of the recessed grooves (recessed ribs) be larger and the depth of the recessed groove be larger as the thickness of the bottle container is reduced. Furthermore, it is preferable that a thickness ratio (T1/T2) of the thickness T1 of the front wall 51 to the thickness T2 of the first side wall 53, which is a side wall distant from the handle 7, of the pair of side walls 53 and 54 be in the range of 0.6 to 0.8 in terms of the prevention of the deformation of the front wall 51 and the stable production of the container body. These thicknesses are measured at the middle height position C7 of the through hole 71 for forming the handle in the height direction, and are measured at the middle position of each wall surface in the circumferential direction of the body portion. [0046] A method of manufacturing the container body is not particularly limited, but it is preferable that the container body be formed by blow molding. Various materials, which can be blow-molded, can be used as the material of the container body, but a polyolefin resin, for example, polypropylene (PP) or polyethylene (PE) is preferable as the material of the container body. Low-density PE, high-density PE, PE in which low-density PE and high-density PE are blended with each other, and the like can be used as the polyethylene (PE).

21 A method of manufacturing the spout cap and a method of manufacturing the measuring cap are also not particularly limited, but it is preferable that the spout cap and the measuring cap be formed by injection molding. For example, various materials, which can be injection-molded, can be used as the material of the spout cap and the material of the measuring cap. [0047] It is preferable that the labels attached to the front and rear walls 51 and 52 be adhesive labels which is to be attached to the outer surface of the body portion by an adhesive. [0048] It is preferable that the adhesive label be formed using a resin layer made of a synthetic resin as a main body. Further, it is also preferable that the adhesive label be formed using paper as a main body. Examples of a label, which is formed using a resin layer made of a synthetic resin as a main body, include a label that includes a label body formed of a resin film and an adhesive layer (preferably a continuous layer) of which one surface is attached to the label body. Various known resin films, which are used as the material of a label, can be used as a resin, which forms the resin film, without being particularly limited. Examples of the resin, which forms the resin film, include polyester such as polyethylene terephthalate (PET), polyethylene, polyolefin such as polypropylene, polyvinyl chloride, and polystyrene. Among them, polyester or polyolefin is preferable and oriented polypropylene (OPP), oriented polyethylene terephthalate (OPET), and low-density polyethylene (LDPE) are preferable. Further, the resin film may be made of a mixture of plural kinds of resins, a copolymer, or a multi-layer laminate. An adhesive, of which one surface can be attached to the label body and the other surface can be attached to a tube body, can be used as the adhesive without being particularly limited. For example, (1) a pressure-sensitive adhesive, (2) a heat-sensitive adhesive, (3) cold glue, or the like can be used as the adhesive.

22 [0049] A pressure-sensitive adhesive label using a pressure-sensitive adhesive can be attached by being pressed, but may be attached to the surface of the body portion so as to come into close contact with the surface of the body portion by being pressed together with heating. A heat-sensitive adhesive label using a heat-sensitive adhesive can be attached through the activation of the adhesive that is caused by the heating of the label. Polyethylene-vinyl acetate (EVA) or the like is preferable as the heat-sensitive adhesive. An adhesive label using a cold glue adhesive is attached after an adhesive is applied to the label when the adhesive label is to be attached (immediately before the adhesive label is attached, or the like). Starch, casein, and the like are preferable as the adhesive, and starch is preferable among them. [0050] Fig. 5 and Fig. 6 are diagrams illustrating container bodies of bottle containers of second and third embodiments of the invention. In the second embodiment, a plurality of inclined recessed grooves 6A, which descend toward a second side wall 54 from a first side wall 53, are formed on a front wall 51 of a body portion of a container body as recessed grooves (recessed ribs) and the plurality of inclined recessed grooves 6A are formed parallel to each other. In the third embodiment, a plurality of inclined recessed grooves 6B, which descend toward a first side wall 53 from a second side wall 54, are formed on a front wall 51 of a body portion of a container body as ribs formed of recessed grooves, and the plurality of inclined recessed grooves 6B are formed parallel to each other. The inclined recessed grooves 6A and other recessed grooves (recessed ribs) are not formed on rear walls 52 of the body portions of the bottle containers of the second and third embodiments. Points, which are not particularly described in the second and third embodiments, are the same as those of the first embodiment. [0051] An inclination angle 0 between a height-direction line L3 and each of the inclined recessed grooves 6A and 6B of the container body of the second and third embodiments is 45'. The ribs formed on the front wall 51 include horizontal recessed grooves having an inclination angle 0 of 900, and the inclination angle 0 between the height-direction line L3 and the rib is preferably 30' or more and more preferably 45' or 23 more. The height-direction line L3 is a straight line perpendicular to the bottom portion 4 in the front view [see Fig. 1(b)] of the container body, and the inclination angle 0 is also measured in the front view of the container body as illustrated in Figs. 5(b) and 6(b). [0052] As illustrated in Figs. 7(a) to 7(c), the ribs formed on the front wall 51 of the body portion of the container body 2 may be intermittent recessed grooves 6', 6A', and 6B' that include small recessed grooves 61 formed of recessed grooves having a short length and lined up on straight lines at intervals. An example illustrated in Fig. 7(a) is an example in which the horizontal recessed grooves 6 of the first embodiment are changed into intermittent recessed grooves 6', an example illustrated in Fig. 7(b) is an example in which the inclined recessed grooves 6A of the second embodiment are changed into intermittent recessed grooves 6A', and an example illustrated in Fig. 7(c) is an example in which the inclined recessed grooves 6B of the third embodiment are changed into intermittent recessed groove 6B'. It is preferable that the length of a gap between the small recessed grooves 61 of the intermittent recessed groove be shorter than the length of each small recessed groove 61. Even in the container bodies 2 illustrated in Figs. 7(a) to 7(c), recessed grooves are not formed on the rear wall of which the inner surface faces the inner surface of the front wall 51. Points, which are not particularly described, are the same as those of the first, second, or third embodiments. [0053] The invention is not limited to the above-mentioned embodiments, and may have various modifications. For example, the spout cap 80 including the spout tube is fixed to the open neck portion of the container body 2 of each of the bottle containers of the above-mentioned embodiments. However, an ordinary topped cylindrical cap, which does not include a spout tube, may be mounted the open neck portion of the container body.

24 [0054] Further, the number of the horizontal recessed grooves, the inclined recessed grooves, or the intermittent recessed grooves, which are formed on the front wall 51 of the body portion, may not be four, and may be one as illustrated in, for example, Figs. 8(a) and 8(b), or may be two, three, or five or more. The upper limit of the number of the horizontal recessed grooves, the inclined recessed grooves, or the intermittent recessed grooves is about ten. When the ribs formed on the front wall are intermittent recessed grooves, the number of each of the small recessed grooves forming the intermittent recessed groove is not counted as one and the number of the entire intermittent recessed groove formed of a plurality of small recessed grooves is counted as one. Furthermore, only one of the four horizontal recessed grooves or four inclined recessed grooves, which are formed on the front wall 51 of the body portion of each of the first to third embodiments, may remain and the other ribs may be removed. [0055] Figs. 10(a) and 10(b) illustrate an example in which meandering recessed grooves 6C are formed on a front wall 51 as recessed grooves so as to extend in a horizontal direction while meandering in a height direction. Further, a recessed groove 6D illustrated in Fig. 11(a) is another example of the intermittent recessed groove, and an interval between the small recessed grooves 61 is equal to or shorter than the half of the length of the small recessed groove 61. [0056] Fig. 12 illustrates an example in which an area ratio (S 1/S2) of the area S1 of a label 10, which is attached to a label-attachment surface of the front wall, to the area S2 of the label-attachment surface of the front wall is low. [0057] Furthermore, Fig. 13 is a diagram illustrating an example in which eight recessed grooves are formed on a front wall of a large bottle container. Moreover, the handle 7 may be present on the right side of the front wall as illustrated in Fig. 1(b) and may be present on the left side of the front wall in the front view of the front wall.

25 [0058] Further, the shape of the label-attachment surface may be a rectangular shape or a trapezoidal shape of which corners are rounded, a circular shape, an elliptical shape, or the like. Furthermore, both the horizontal cross-section and the vertical cross-section of the rear wall 52 may have the shape of a circular arc that is convex toward the outside of the container. [0059] Moreover, as illustrated in Fig. 14(a), a cap 8A of the invention includes a topped cylindrical liquid containing portion 87 and a mounting portion 88 that is formed with an interval interposed between the liquid containing portion 87 and itself and is mounted on the open neck portion 3 of the container body 2, and when the cap is mounted on the open neck portion 3 as illustrated in Fig. 14(c), a part of the liquid containing portion 87 may be a portion E that is inserted into the body portion 5 of the container body 2. The mounting portion 88 of the illustrated example is mounted on the open neck portion 3 by screwing, but the mounting portion 88 may be mounted on the open neck portion 3 by other methods, such as fitting, except for screwing. The cap 8A includes a liquid containing portion that includes a tube portion 87 which has a ceiling and of which the other end is opened, and a mounting portion 88 that is formed outside the liquid containing portion with an interval interposed therebetween and is mounted on the open neck portion 3. The other end of the tube portion 87 of the liquid containing portion hangs down to the lower portion of the open neck portion through the open neck portion 3 when the cap 8A is mounted on the open neck portion 3. Even in the cap 8A, a portion hanging down to the lower portion of the open neck portion, more specifically, the portion E inserted into the body portion 5 is preferably separated from the level 89 of contents. [0060] Portions, which have not been described, of one embodiment, which has been described above, and components included in only the embodiment can be appropriately applied to other embodiments, and the components of the respective embodiments can be appropriately substituted for each other.

26 [Example] [0061] The invention will be described in more detail below by using Examples and Comparative Example, but the invention is not limited at all by the description of Examples and Comparative Example to be described below. [0062] [Example 1] A container body having the same shape as the container body of the bottle container of the first embodiment was manufactured by direct blow molding using a polyolefin resin as a raw material. The dimensions of the manufactured container body included the distance Li of 100.8 mm, the distance L2 of 172 mm, and the height T of 232.5 mm. Further, the length of each of the four horizontal recessed grooves were set so that the shortest distance between the first ridgeline 56 and one end of the horizontal recessed groove in the longitudinal direction was 10 mm and the shortest distance between the second ridgeline 57 and the other end thereof was 10 mm, and the four horizontal recessed grooves were disposed so that the height between the bottom portion and the horizontal recessed groove formed at the lowermost position was 45 mm and a distance between adjacent horizontal recessed grooves among the other three horizontal recessed grooves was 25 mm. The width of each recessed groove was 4.5 mm and the depth of each recessed groove was 3.0 mm. The internal volume of the container body was 2683 cm 3 , and the mass of the resin of the container body per an internal volume of 100 cm 3 was 5 g. [Examples 2 and 3] Container bodies of Examples 2 and 3 were manufactured in the same manner as Example 1 except that the horizontal recessed grooves formed on the front wall of the body portion were modified in the following manner. Example 2: only one horizontal recessed groove was formed as illustrated in Fig. 8(a). The width of the recessed groove was 10 mm and the depth of the recessed groove was 4 mm. Example 3: only two horizontal recessed grooves were formed as illustrated in Fig. 8(c). The width of the recessed groove was 10 mm and the depth of the recessed groove was 4 mm.

27 [0063] [Comparative Example 1] A container body of Comparative Example 1 was manufactured in the same manner as Example 1 except that a recessed groove (rib) was not formed even on the front wall as in the rear wall. [0064] [Evaluation of deformability] After 2400 mL (2.4 kg) of water was put in the container body of each of Example and Comparative Examples, a cap made of rubber was mounted on an open neck portion 3 as illustrated in Fig. 15(a) to hermetically seal the inside of the container body. In this state, 180 mL of air present in a head space above the level of liquid was sucked out by a syringe. When the container body was hermetically sealed before the suction of air, a distance between the level of the liquid contents (water) and the lower end of the open neck portion was about 10 mm. Further, the amount of deformation of the body portion, which was obtained before and after the suction of air, [see Fig. 15(b)] was measured by a scale at a position illustrated in Fig. 15(a) where the amount of deformation was measured on each of the front wall and the rear wall. Results thereof were described below. [Amount of deformation] Example 1: 3 mm on the front wall, 10 mm on the rear wall, and 13 mm in total Example 2: 5.5 mm on the front wall, 8.5 mm on the rear wall, and 14 mm in total Example 3: 3 mm on the front wall, 11 mm on the rear wall, and 14 mm in total Comparative Example 1: 9 mm on the front wall, 9 mm on the rear wall, and 18 mm in total [0065] [Evaluation] In regard to the results of Examples 1 to 3, the amount of deformation of the 28 front wall was smaller than the amount of deformation of the rear wall in comparison with Comparative Example 1, and the total amount of deformation was also reduced. Since a label will be attached to the front wall of which the amount of deformation was small, the deformation of the label can be prevented. Further, it is understood that the appearance of the bottle container as a commercial product can be satisfactorily maintained if the bottle container is displayed so that the label attached to the front wall faces a customer. Industrial Applicability [0066] According to the bottle container of the invention, even though pressure in the bottle is reduced, the rear wall of the bottle container not including the recessed groove (recessed rib) is deformed but the front wall of the bottle container including the recessed groove (recessed rib) is not easily deformed. Accordingly, the deterioration of the appearance of the label attached to the front wall can be prevented, and the appearance of the commercial product can also be satisfactorily maintained when the commercial product is being displayed if the commercial product is displayed so that the label attached to the front wall faces a customer as in, for example, the method of displaying a commercial product of the invention. [0067] Comprises/comprising and grammatical variations thereof when used in this specification are to be taken to specify the presence of stated features, integers, steps or components or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
