The present invention relates to a pinch-grip bottle-type container.

Conventionally, there has been known a pinch-grip type bottle-type container in which finger rest recesses are formed separately in a pair of side regions of a body that face each other across a central axis of a mouth, a back region located between the pair of side regions, and the finger rest recesses are used as a grip portion, and the finger rest recesses have a bottom surface facing radially outward and a side wall surface rising radially outward from an outer periphery of the bottom surface.As a pinch-grip type bottle-type container of this type, for example, as shown in the following Patent Document 1, a configuration is known in which a plurality of ridges extending across the bottom surface and a rear wall surface located at the rear end of the rear region side of the side wall surfaces are provided along the central axis.
By providing a plurality of ridges on the finger rest recess, it is possible to prevent the pinch grip type bottle container from slipping out of the hand when the container is picked up by grasping the grip portion.

JP 2019-202796 A

However, in the case of the conventional pinch-grip bottle-type containers, if the container is made thin-walled for environmental reasons, when an impact load from the contents or internal pressure acts on the finger rest recess, stress may concentrate on the ridge, causing cracks in the bottom surface.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide a pinch-grip bottle-type container that prevents the container from slipping out of the hand when the container is picked up by grasping the grip portion, and that is less likely to cause cracks in the bottom surface of the finger rest recess even if the container is made thin.

A pinch-grip bottle-type container according to one aspect of the present invention has a pair of side regions of a body portion that face each other across a central axis of a mouth portion in a radial direction, and a finger rest recess is formed in each of the side regions. A back region located between the pair of side regions and the finger rest recess serve as a grip portion. The finger rest recess has a bottom surface facing radially outward and a side wall surface rising radially outward from an outer circumferential edge of the bottom surface. At least a rear wall surface of the side wall surfaces that is located at the rear end on the back region side has a front region that is located on the opposite side of the back region in the body portion. a plurality of ribs extending in the fore-aft direction facing each other are provided along the central axis direction, the ribs are located in a portion of the finger rest recess that is rearward of the fore-aft center of the bottom surface, a plurality of protruding ribs connecting the side wall surfaces in the fore-aft direction are provided on the bottom surface at intervals in the central axis direction, a plurality of the ribs are provided on the rear wall surface in portions located between the protruding ribs adjacent to each other in the central axis direction, a front end of the rib is located at the connection portion between the bottom surface and the rear wall surface, and a rear end of the rib is located forward of the rear edge of the rear wall surface .

The rib portion is provided avoiding the front-to-rear central portion of the bottom surface, which is prone to deformation when an impact load from the contents or internal pressure, etc., acts on the finger rest recess, so that even if an impact load, etc., acts on the finger rest recess, the occurrence of cracks in the bottom surface can be suppressed.
Since the rib portion is provided on the rear wall surface of the side wall surface of the finger rest recess, when the grip portion is grasped, the fingertips can be easily pressed against the rib portion, and when the pinch grip type bottle-type container is lifted in this state, the container can be prevented from slipping out of the hand.
As a result, when a pinch grip type bottle-type container is lifted by grasping the grip portion, the container is prevented from slipping out of the hand, and even if the container is made thin, cracks are less likely to occur on the bottom surface of the finger rest recess.
Since a protruding rib is provided on the bottom surface, it is possible to improve the rigidity of the bottom surface, and it is possible to prevent the bottom surface from deforming when an impact load from the contents or the like acts on the finger rest recess, thereby reliably preventing the occurrence of cracks in the bottom surface.
Since the rib portions are provided in multiple portions on the rear wall surface located between adjacent protruding ribs in the direction of the central axis, when the grip portion is grasped, it is possible to press the fingertips against the rib portions while being supported in the direction of the central axis by the protruding ribs, thereby reliably preventing the lifted pinch grip type bottle-type container from slipping out of the hand.

The rib may extend straight in the front-to-rear direction.

Since the rib extends straight in the front-to-rear direction, when the grip is grasped, the rib can be firmly hooked onto the fingertips, reliably preventing the pinch-grip bottle-type container from slipping out of the hand.

A rear end portion of the protruding rib may be located at a connection portion between the bottom surface and the rear side wall surface.

The front end of the rib and the rear end of the protruding rib are located at the connection between the bottom surface and the rear wall surface of the finger rest recess, so the pinch-grip bottle-type container can be securely prevented from slipping out of the hand when lifted.

This invention makes it possible to prevent the pinch-grip bottle-type container from slipping out of the hand when the grip is grasped and to prevent cracks from forming on the bottom surface of the finger rest recess even if the container is made thin.

FIG. 1 is a side view of a pinch-grip bottle-type container according to one embodiment. FIG. 2 is a rear view including a partial vertical cross section of the pinch-grip bottle-type container shown in FIG. 1 . 3 is a cross-sectional view taken along the line III-III in FIG. 1 and FIG. 2.

Hereinafter, a pinch-grip bottle-type container according to one embodiment will be described with reference to the drawings.
As shown in Figures 1 and 2, the pinch-grip bottle-type container 1 according to this embodiment includes a mouth 11, a shoulder 12, a body 13, and a bottom 14, which are generally arranged in this order with their central axes aligned on a common axis. The internal volume of the pinch-grip bottle-type container 1 is large enough to hold, for example, 200 ml to 4000 ml of contents. In the illustrated example, the pinch-grip bottle-type container 1 is large enough to hold approximately 2700 ml of contents.

Hereinafter, the common axis will be referred to as the central axis O, the mouth 11 side along the direction of the central axis O will be referred to as the upper side, and the bottom 14 side will be referred to as the lower side, the direction along the central axis O will be referred to as the up-down direction (central axis direction), the direction that intersects the central axis O when viewed from the up-down direction will be referred to as the radial direction, and the direction that rotates around the central axis O will be referred to as the circumferential direction.
The pinch-grip bottle-type container 1 is integrally formed from a synthetic resin material by blow molding a preform formed into a bottomed cylindrical shape by injection molding. A cap (not shown) is attached to the mouth 11. The mouth 11, shoulder 12, and bottom 14 each have a circular cross-sectional shape perpendicular to the central axis O.

A finger rest recess 15 is formed in each of a pair of side regions 13a of the body 13 that face each other radially across the central axis O. The back region 13b of the body 13, located between the pair of side regions 13a, and the finger rest recess 15 form the grip portion G that the user grasps when lifting the pinch-grip bottle-type container 1. The finger rest recess 15 and grip portion G are provided in a portion of the body 13 that is located below the upper portion.

As shown in FIG. 3, the rear region 13b is the shorter of the pair of regions located between the pair of side regions 13a in the body 13 in the circumferential direction. A vacuum absorption panel 13c is formed in the rear region 13b to prevent deformation of the body 13 that is difficult to restore due to the reduced pressure inside the pinch-grip bottle-type container 1.

Hereinafter, the side on which the back region 13b is located with respect to the central axis O is referred to as the rear side, and the side opposite the back region 13b with respect to the central axis O is referred to as the front side. The part of the body 13 that is located on the opposite side of the back region 13b across the central axis O in the radial direction is referred to as the front region 13d. The radial direction in which the back region 13b and the front region 13d face each other is referred to as the front-rear direction.

1, the finger rest recess 15 has a rectangular shape that is long in the vertical direction when viewed from the front from the outside in the radial direction. The finger rest recess 15 has a bottom surface 15a facing the outside in the radial direction, and side wall surfaces 15b and 15c rising from the outer periphery of the bottom surface 15a toward the outside in the radial direction.
2, the bottom surface 15a extends linearly in a vertical cross-sectional view. A plurality of protruding ribs 18 are provided on the bottom surface 15a at intervals in the vertical direction. The protruding ribs 18 connect the side wall surfaces of the finger rest recess 15 in the front-rear direction. The protruding ribs 18 are formed in a rectangular parallelepiped shape that is long in the front-rear direction.

The multiple side wall surfaces 15b, 15c include a rear wall surface 15b located at the rear end and a lower wall surface 15c located at the lower end.

The lower wall surface 15c extends radially outward from the lower edge of the bottom surface 15a and faces upward. The lower wall surface 15c extends downward as it faces radially outward. The radial inner edge of the lower wall surface 15c and the lower edge of the bottom surface 15a are smoothly connected without any steps. The radial outer edge of the lower wall surface 15c forms the lower edge of the finger rest recess 15.

A sloping portion 16 is formed in the side region 13a, extending radially outward as it moves downward from the lower edge of the finger rest recess 15. The angle of inclination of the sloping portion 16 with respect to the central axis O is smaller than the angle of inclination of the lower wall surface 15c of the finger rest recess 15 with respect to the central axis O. A connection portion 17 between the upper edge of the sloping portion 16 and the lower edge of the finger rest recess 15 forms a corner that is sharpened radially outward. This connection portion 17 extends straight in the front-to-rear direction when the finger rest recess 15 is viewed from the front.

A reinforcing groove 21 is formed in both the finger rest recess 15 and the inclined portion 16 at the connection portion 17 between the finger rest recess 15 and the inclined portion 16. The reinforcing groove 21 is located in the center of the finger rest recess 15 in the front-to-rear direction. The vertical size of the reinforcing groove 21 is greater than the vertical size of the reinforcing groove 21, and the reinforcing groove 21 extends in the vertical direction. The reinforcing groove 21 is located below the lower edge of the bottom surface 15a of the finger rest recess 15, and is formed integrally with the lower wall surface 15c and the upper portion of the inclined portion 16. The reinforcing groove 21 is located in a portion of the lower wall surface 15c that is located radially outward from the radial inner end portion.

The width of the upper edge of the reinforcing groove 21 is wider than the width of the lower edge of the reinforcing groove 21. The width of the reinforcing groove 21 increases from the bottom to the top. The reinforcing groove 21 has an inverted triangular shape in a front view seen from the outside in the radial direction.
The inner surface of the reinforcing groove 21 is formed as a concave curved surface extending radially inward toward the center in the front-rear direction. The vertical distance between the lowermost protruding rib 18 among the multiple protruding ribs 18 and the reinforcing groove 21 is equal to the distance between adjacent protruding ribs 18 in the vertical direction.

As shown in FIG. 3, the rear wall surface 15b extends radially outward from the rear end edge of the bottom surface 15a and faces forward. The rear wall surface 15b extends rearward as it extends radially outward. The radial inner end edge of the rear wall surface 15b and the rear end edge of the bottom surface 15a are smoothly connected without any steps. In a cross section perpendicular to the central axis O, the finger rest recess 15 has a concave curved shape recessed radially inward.

A plurality of ribs 19 extending in the front-rear direction are provided on the rear wall surface 15b along the up-down direction. The ribs 19 are recessed radially inward. The ribs 19 may protrude radially outward. The recess amount of the ribs 19 is smaller than the protruding amount of the protruding rib 18. The ribs 19 extend straight in the front-rear direction. The ribs 19 may extend in a direction intersecting the front-rear direction and the up-down direction.
The rib portion 19 is located rearward of the center in the front-to-rear direction on the bottom surface 15a of the finger rest recess 15. The rib portion 19 is provided only on the rear end portion of the bottom surface 15a. The entire bottom surface 15a is formed smooth except for the portion where the rib portion 19 and the protruding rib 18 are located.

As shown in FIG. 1, the rib portions 19 are provided in multiples on the rear wall surface 15b in portions located between adjacent protruding ribs 18 in the up-down direction. In the illustrated example, the multiple rib portions 19 are also provided on the rear wall surface 15b in portions located above the uppermost protruding rib 18 among the multiple protruding ribs 18. The front end of the rib portion 19 and the rear end of the protruding rib 18 are located at the connection portion 15d between the bottom surface 15a and the rear wall surface 15b. The rear end of the rib portion 19 is located forward of the rear edge of the rear wall surface 15b.

As described above, according to the pinch-grip bottle-type container 1 of this embodiment, the rib portion 19 is provided to avoid the center portion in the front-to-rear direction of the bottom surface 15a, which is easily deformed when an impact load from the contents or internal pressure acts on the finger rest recess 15. Therefore, even if an impact load or the like acts on the finger rest recess 15, the occurrence of cracks in the bottom surface 15a can be suppressed.

Since the rib portion 19 is provided on the rear wall surface 15b of the finger rest recess 15, when the grip portion G is grasped, the fingertips can be easily pressed against the rib portion 19, and when the pinch grip type bottle-type container 1 is lifted in this state, the container 1 can be prevented from slipping out of the hand.
