  The bottle container 10 shown in FIGS. 1 to 3 takes into consideration ease of holding and pouring without having a handle even if it has a large capacity and is heavy. The bottle container 10 includes a container main body 20 that can be gripped with one hand, and a spout portion that is provided on the upper surface (upper opening) 20A of the container main body 20 to pour out contents such as a liquid main body. 40. The container main body 20 has a large capacity of 2000 mL, for example. Regarding the volume, the effect of the present invention can be naturally obtained even in a small volume. However, in the container having a capacity of 400 mL or more, particularly 600 mL or more, the present invention is compared with other forms of containers. The effect of becomes clear. The spout 40 is constituted by a spout cylinder 41 that is attached to the opening of the container body 20. In the bottle container 10, the container main body 20 and the spout 40 (pouring cylinder 41) are made of a synthetic resin molded body.

  The bottle container 10 is provided so as to be opposed to the first side face 21 and the first side face 21 that are in contact with the first finger when the container main body 20 is gripped with one hand (right hand in the case of FIG. 1). The third side surface 23 is provided so as to connect the second side surface 22 where the fifth finger is in contact with the finger, the first side surface 21 and the second side surface 22 and is in contact with the palm.

  The container body 20 of the present embodiment has an oblong shape as shown in FIG. 3 as a cross-sectional shape, and both side surfaces along the long axis direction are defined as a first side surface 21 and a second side surface 22 and are orthogonal to the long axis. One side surface along the direction is a third side surface 23. That is, as shown in FIG. 1, the side surfaces are provided in the vertical direction of the container body 20 when the bottom surface 20 </ b> B is on the lower side.

  Here, in this specification, the thumb is referred to as the first finger, and the index finger is referred to as the second finger, the middle finger is referred to as the third finger, the ring finger is referred to as the fourth finger, and the little finger is referred to as the fifth finger.

  In addition, the finger touching means that the abdomen of the finger touches each side surface. When the bottle container of the present application is held with the left hand, the first side surface indicates the portion indicated by reference numeral 22 in FIG. 2 and the second side surface indicates the portion indicated by reference numeral 21.

  The container body 20 includes a recess 31 that is continuously formed so as to extend over the first side surface 21, the second side surface 22, and the third side surface 23, and can accommodate a finger, and the hand 50 including the first finger and the second finger. The grip part 30 having the upper end standing part 32 with which the upper edge part 51 can come into contact is formed. That is, the grip part 30 is formed in the circumferential direction of FIG. At this time, the concave portion 31 of the grip portion 30 is continuous so as to extend over the flat portions 31A on both sides formed on the first side surface 21 and the second side surface 22, and the first side surface 21, the second side surface 22, and the third side surface 23. And a curved surface portion 31B that connects the flat portions 31A on both sides. Here, the “concave portion that can hold a finger” refers to a concave portion that can be received by bringing the first to fifth fingers and the palm into contact with each other when the container body 20 is gripped as shown in FIGS. 4 and 5. It is. In addition, the “upper end standing part with which the upper edge of the hand can come into contact” means that when the container body 20 is gripped as shown in FIGS. 4 and 5, or when the container body 20 is gripped and lifted, It is an upper end standing part which the upper edge part of can contact | abut.

  When the flat portion 31A is viewed from the side of the first side surface 21 or the second side surface 22, when the bottle container is sold with a specified amount of contents (for example, when the bottle is sold as “1 liter of internal capacity”), the specified amount is It is preferably provided at a position including the center of gravity position G in the case where “1 liter” is filled (FIG. 1). When the flat portion is provided at such a position, even a bottle container having a large capacity and a heavy weight can be easily grasped and the contents can be easily poured into the measuring cap.

  The shape of the flat portion 31 </ b> A is preferably wide on the third side surface 23 side so as to conform to the shape of the hand when the container body is gripped by hand. In the embodiment of the present application, as shown in FIG. 1, when viewed from the side of the first side surface 21, it has a substantially “inverted D” shape. On the other hand, as shown in FIG. 4, when viewed from the side of the second side surface 22, the shape is substantially “D”. By making the flat part 31A into such a shape, the user of the container 10 of the present invention naturally brings the palm into contact with the third side surface 23, and then makes the first finger contact the first side surface 21, and the second finger to the fifth finger. A finger is brought into contact with the second side surface 22 before being gripped (FIGS. 5 and 6). At this time, it is preferable that the extraction pipe | tube 41 of the spout part 40 is opening toward the said 3rd side surface 23 from a viewpoint of the ease of pouring of the content. 4 to 6, reference numeral 50 denotes a hand, 51 denotes an upper edge portion of the hand, and 52 denotes a lower edge portion of the hand.

  By making the thickness of the flat portion 31A thinner than the thickness of the curved surface portion 31B, when the cap of the bottle container 10 is opened, the flat portion 31A is deformed inside the container main body portion 20 according to the gripping force of the hand. Even if the bottle container 10 has a large capacity and a heavy weight, it is easy to grasp, and therefore, it is easy to grasp and pour the contents.

  In addition, when filling a general container (container other than the bottle container of the present invention) with a detergent containing a surfactant as the contents, if the bottle container 10 is left for a certain period with the cap closed, Oxygen in the container may be absorbed by the surfactant, and the container may become negative pressure and the container may be deformed. On the other hand, in the case of the bottle container 10 of the present invention, by making the thickness of the flat part 31A thinner than the thickness of the curved part 31B, the flat part 31A is more actively deformed than the other part of the container, The appearance of the entire bottle container 10 can be maintained. That is, even if a buckling phenomenon (a dent phenomenon) occurs in the bottle container 10 due to negative pressure, the flat portion 31A is deformed to the inside of the container while maintaining flatness, so that the appearance of the entire bottle container 10 is not greatly affected. It has an effect and can also serve as a reduced pressure deformation panel.

  As long as the flat portion 31A has a maximum width direction L of 30 mm to 50 mm and a maximum vertical length Y of 50 mm to 70 mm, it is easy to grip even a large capacity and heavy bottle container 10. Easy to pour the contents.

  The flat portion 31A may be flat compared to the curved surface portion 31B, and need not be completely flat.

  Further, the concave portion 31 of the gripping portion 30 forms a convex strip portion 31D at the boundary between the flat portion 31A and the curved surface portion 31B. On the first side surface 21 and the second side surface 22 on which the flat portion 31A and the curved surface portion 31B are provided, the protruding line portion 31D is a fold line (ridge ridgeline) where the flat portion 31A and the curved surface portion 31B meet to form an outward projection. ), And is a portion that prevents the fingers from slipping when the container body 20 is gripped and tilted to pour out the contents.

  It is preferable that the holding part 30 further has a lower end standing part 33 with which the lower edge part 52 of the hand including the fifth finger can come into contact. The lower end standing portion 33 is formed on at least the first side surface 21 and the second side surface 22 (the first side surface 21, the second side surface 22, and the third side surface 23 if necessary). When the lower end standing portion 33 is provided, the lower end standing portion 33 serves as a stopper for preventing the fifth finger from slipping when the heavy container body 20 is tilted to pour out the contents, and the contents are poured. It becomes easy to take out (FIG. 4).

  In the grip portion 30, the upper end standing portion 32 is an upward convex portion of each of the first side surface 21, the second side surface 22, and the third side surface 23 at a substantially right angle or an obtuse angle from the flat portion 31 </ b> A and the curved surface portion 31 </ b> B of the recess 31. It is a portion that rises toward 21A, 22A, and 23A. In other words, the upper end upright portion 32 has an upward convex portion 21A of the first side surface 21 or the second side surface 22 at a substantially right angle or an obtuse angle of inclination θ1 from the flat portion 31A and the curved surface portion 31B when viewed from the third side surface 23. , 22A (see FIG. 2).

  Here, the upper convex portions 21 </ b> A and 22 </ b> A refer to portions located above the upper end standing portion 32 on each side surface.

  By setting the inclination angle θ1 to a substantially right angle or an obtuse angle, when gripping, the upper edge portion 51 of the hand 50 is caught by the upper end standing portion 32, and the container 10 is easily lifted, and the gripping property is improved. . Note that the upper end upright portion 32 is a portion where the upper edge portion 51 of the hand 50 abuts when the container 10 is gripped and lifted, and thus serves as a gripping reference position.

  The inclination angle θ1 is preferably 90 degrees from the viewpoint of facilitating lifting of the container 10, but in order to facilitate removal from the mold after the container 10 is molded, a so-called draft angle can be taken into consideration. It is also possible to take into consideration that the molten resin is spread to every corner of the mold when the mold is molded to prevent the container thickness from being partially reduced. In such a case, the inclination angle θ1 is preferably 90 to 150 degrees, more preferably 100 to 150 degrees, and further preferably 125 to 140 degrees.

  In the gripping part 30, the lower end standing part 33 is provided with lower convex parts 21B, 22B on the first side face 21, the second side face 22, and the third side face 23 at an obtuse angle from the flat part 31A and the curved face part 31B of the concave part 31, respectively. It is the part that falls towards 23B. That is, the lower end standing portion 33 is moved from the flat portion 31A and the curved surface portion 31B to the lower convex portions 21B and 22B of the first side surface 21 or the second side surface 22 at an obtuse angle θ2 when viewed from the third side surface 23. This is the part that falls down (FIG. 2). By setting the obtuse inclination angle, the lower end standing portion 33 can be used as a stopper for preventing the fifth finger from slipping when the heavy container 10 is gripped and tilted regardless of the size of the hand. . That is, by making the inclination angle θ2 an obtuse angle, the width of the lower end standing portion 33 is widened, and when the container 10 is lifted, the upper edge portion 51 of the hand 50 comes into contact with the upper end standing portion 32 that is the reference position for gripping. In this case, regardless of the size of the hand, the lower edge portion 52 of the hand 50 comes into contact with the lower end standing portion 33 and can serve as a stopper for preventing the fifth finger from slipping. If the fifth finger slips, the container 10 is tilted and the contents are poured out, and the contents may be spilled in some cases.

  The inclination angle θ2 is preferably 150 ° to 170 °, more preferably 155 ° to 170 °, and even more preferably 160 ° to 170 ° from the viewpoint of preventing slipping of the fifth finger regardless of the size of the hand. Preferably, it is 160 to 165 degrees.

  The inclination angle θ1 and the inclination angle θ2 have a relationship of θ1 <θ2.

  In the concave portion 31 of the grip portion 30, the upper edge portion 51 of the hand extending from the tip of the first finger to the tip of the second finger is located between the upper convex portion 23 </ b> A and the lower convex portion 23 </ b> B of the third side surface 23. The curved center portion 31C having a length H (FIGS. 1 and 2) that allows the lower edge 52 of the hand including the fifth finger to contact the lower end standing portion 33 is connected to the center ( The center of the curved surface portion 31 </ b> B in the direction along the outer periphery of the transverse cross section of the container main body portion 20. The center of the curved surface portion 31B substantially coincides with the mold parting line P when the container 10 is molded. Accordingly, the length H is the length (third side surface 23) from the upper end to the lower end of the recess 31 in the direction in which the mold parting line P is formed (the vertical direction from the container bottom surface 20B to the spout portion 40). Projection length when viewed from the side).

  In the container body 20, the length H of the curved central portion 31 </ b> C of the concave portion 31 of the gripping portion 30 is the statistical minimum hand width (for example, 65.5 mm) for adults, and the length H of the curved central portion 31 </ b> C is used. The length obtained by adding the length K (FIGS. 1 and 2) of the lower end standing portion 33 to the statistical maximum hand width (for example, 95.0 mm) of an adult. The statistical minimum hand width and maximum hand width for adults can be found in, for example, the “Collection of Human Body Size Data for Design” manual (Edited by Biotechnology Institute of Industrial Technology, Ministry of International Trade and Industry, 1996, page 195) Can be based on. The length K is a projection length when the third side surface 23 is viewed from the side.

  In the container main body 20, the curved central portion 31 </ b> C of the concave portion 31 of the gripping portion 30 is substantially perpendicular to the bottom surface 20 </ b> B of the container main body 20. It is preferable from the viewpoint of easy lifting. In addition, the upper end standing part 32 of the gripping part 30 is substantially parallel to the bottom surface 20B of the container main body part 20 so that the upper edge part 51 of the hand 50 comes into contact with the upper end standing part 32 and the container is easily lifted. It is preferable from the viewpoint.

  In the bottle container 10, when the spout portion 40 provided on the upper surface of the container main body 20 is constituted by the above-described spout tube 41, the opening 41 </ b> A of the spout tube 41 opens toward the third side surface 23. It is preferable.
