Summary of the Invention

Problems to be Solved by the Invention

[0004] In a pinch grip type bottle-shaped container, when the diameter of the body portion increases, the width, which is the circumferential size of the back surface region, becomes wider, and there are cases where a person with small fingers cannot strongly grip the grip portion.

[0005] One of the objects of the present invention is to provide a pinch grip type bottle-shaped container that allows a person with small fingers to strongly grip the grip portion.

Means for Solving the Problems

[0006] A pinch-grip type bottle container according to one aspect of the present invention has a body portion in which grip recesses are formed separately on a pair of side regions that face each other, sandwiching the central axis of the mouth in the left-right direction within the radial direction, and a rear region located between the pair of side regions, and the grip recesses constitute the grip portion, and the grip recess comprises a bottom surface facing left-right and a side wall surface rising left-right from the outer peripheral edge of the bottom surface, and the side wall surface comprises a rear side wall surface that defines the rear end of the grip recess on the rear region side, and the rear portion of the rear side wall surface that is connected to the rear region faces left-right, and upper finger rest recesses are formed separately at the upper end of the bottom surface of each of the grip recesses, and at the rear of the rear side wall surface, a constricted portion is formed in the front-rear direction perpendicular to the left-right direction within the radial direction with respect to the upper finger rest recess, opening to the rear region and narrowing the width which is the size of the rear region in the left-right direction.

[0007] Each grip recess has a separate upper finger rest recess formed at the upper end of its bottom surface, and a constricted portion is formed at the rear of the rear wall surface in the portion adjacent to the upper finger rest recess in the front-to-back direction, narrowing the width of the back area. Therefore, when lifting a pinch-grip type bottle container, by grasping the constricted portion, even people with small fingers can reach the upper finger rest recesses of each pair of grip recesses individually with their fingertips while covering the back area with their palm, allowing them to grip the grip firmly.

[0008] A lower finger rest recess may be formed separately on the bottom surface of each of the grip recesses, in the portion located directly below the upper finger rest recess.

[0009] Since a separate lower finger rest recess is formed on the bottom surface of each grip recess, directly below the upper finger rest recess, it is possible to insert different fingertips into both the upper and lower finger rest recesses simultaneously when gripping the grip, allowing for a firm and secure grip.

[0010] When viewed from above or below, the rear region may be inscribed in an arc having a radius of curvature smaller than that of the front region located on the opposite side of the rear region, straddling the central axis radially within the torso.

[0011] When viewed from above or below, the back region is inscribed within an arc with a radius of curvature smaller than that of the front region, thus ensuring that the width of the back region is significantly reduced.

[0012] In the radial direction, the front-rear direction in which the rear region and the front region face each other. The size of the torso along the line but, Of the radial directions, The pair of aforementioned side regions face each other in the left-right direction. The size of the torso along the line It's okay for it to get bigger.

[0013] Size of the torso along the front-to-back direction but, The size of the torso along the left-right direction Because it is larger, it can definitely narrow the width of the back area. [Effects of the Invention]

[0014] According to this invention, even people with small fingers can firmly grip the handle. [Brief explanation of the drawing]

[0015] [Figure 1] This is a side view of a pinch-grip type bottle container shown as one embodiment. [Figure 2] Figure 1 is a rear view including a partial vertical cross-section of the pinch-grip type bottle container. [Figure 3] These are cross-sectional views taken along the line III-III in Figures 1 and 2. [Modes for carrying out the invention]

[0016] A pinch-grip type bottle container according to one embodiment will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the pinch grip type bottle-shaped container 1 according to this embodiment includes a mouth portion 11, a shoulder portion 12, a body portion 13, and a bottom portion 14, and these 11 to 14 are arranged in this order along the central axis O of the mouth portion 11 in a schematic configuration. The internal volume of the pinch grip type bottle-shaped container 1 is sized to be filled with, for example, 200 ml or more and 4000 ml or less of contents. In the illustrated example, the pinch grip type bottle-shaped container 1 is sized to be used for filling with approximately 2200 ml of contents.

[0017] Hereinafter, along the central axis O of the mouth portion 11, the side of the mouth portion 11 is referred to as the upper side, the side of the bottom portion 14 is referred to as the lower side, the direction along the central axis O is referred to as the vertical direction, and when viewed from the vertical direction, the direction intersecting the central axis O is referred to as the radial direction, and the direction of orbiting around the central axis O is referred to as the circumferential direction. The pinch grip type bottle-shaped container 1 is formed by blow molding a preform formed into a bottomed cylindrical shape by injection molding, and is integrally formed of a synthetic resin material. A cap (not shown) is attached to the mouth portion 11.

[0018] In the body portion 13, grip recesses 15 are respectively formed in a pair of side surface regions 13a that face each other across the central axis O in the radial direction. Among the body portion 13, the back surface region 13b located between the pair of side surface regions 13a and the grip recesses 15 serve as a grip portion G that is gripped when the user lifts the pinch grip type bottle-shaped container 1. The grip recesses 15 and the grip portion G are provided in an intermediate portion located between the upper end portion and the lower end portion of the body portion 13. Circumferential grooves 13e that continuously extend over the entire circumferential length are respectively formed in the upper end portion and the lower end portion of the body portion 13.

[0019] As shown in FIG. 3, the back surface region 13b is the region with the shorter circumferential length among the pair of regions located between the pair of side surface regions 13a in the body portion 13. A decompression absorption panel 13c for preventing deformation of the body portion 13 that is difficult to restore due to decompression inside the pinch grip type bottle-shaped container 1 is formed in the back surface region 13b.

[0020] Hereinafter, with respect to the central axis line O, the side where the back region 13b is located is referred to as the rear side, and the opposite side of the back region 13b is referred to as the front side. A portion of the body 13 that is located on the opposite side of the back region 13b that sandwiches the central axis line O in the radial direction is referred to as the front region 13d. In the radial direction, the direction in which the back region 13b and the front region 13d face each other is referred to as the front-rear direction, and the direction orthogonal to the front-rear direction is referred to as the left-right direction.

[0021] In each of the shoulder 12, the body 13, and the bottom 14, the diameter in the front-rear direction is larger than the diameter in the left-right direction. The diameter B in the front-rear direction of the body 13 is 0.6 times or more and 1.0 times or less the vertical size A of the body 13. Thereby, the vertical size of the pinch-grip type bottle-shaped container 1 is suppressed. The pinch-grip type bottle-shaped container 1 may be used, for example, as a refill container filled with the content for refilling this container. Note that the shoulder 12 extends inward in the radial direction as it goes upward, and the bottom 14 extends inward in the radial direction as it goes downward.

[0022] When viewed from the vertical direction, the back region 13b is inscribed in an arc C with a radius of curvature R2 that is smaller than the radius of curvature R1 of the front region 13d. In the illustrated example, in the back region 13b, both end portions in the circumferential direction are in contact with the arc C, and the intermediate portion in the circumferential direction is located radially inward of the arc C. When viewed from the vertical direction, the radius of curvature R2 of the arc C (about 58 mm in the illustrated example) is 0.7 times or more and less than 1.0 times the radius of curvature R1 of the front region 13d (about 66 mm in the illustrated example).

[0023] As shown in FIG. 1, the grip recess 15 has an elongated rectangular shape in the vertical direction in a front view seen from the left-right direction. In a front view seen from the left-right direction, the lower end portion of the front end portion of the grip recess 15 is formed in a chamfered shape that extends rearward as it goes from above to below. The grip recess 15 includes a bottom surface 16 facing the left-right direction and side wall surfaces 17 that rise in the left-right direction from the outer peripheral edge of the bottom surface 16. As shown in Figure 2, the bottom surface 16 extends in a straight line in a vertical cross-sectional view along the vertical direction. The side wall surface 17 includes a rear side wall surface 18 that defines the rear end of the grip recess 15.

[0024] As shown in Figure 3, the front portion 18a of the rear wall surface 18, which is connected to the outer edge of the bottom surface 16, extends towards the rear as it moves away from the bottom surface 16 in the left-right direction. The rear portion 18b of the rear wall surface 18, which is connected to the rear surface region 13b, extends in the front-rear direction and faces left-right.

[0025] As shown in Figures 1 and 2, a separate upper finger rest recess 21 is formed at the upper end of the bottom surface 16 of each grip recess 15. The upper finger rest recess 21 extends across the entire front-to-back area of ​​the bottom surface 16. The bottom surface of the upper finger rest recess 21 extends linearly in a vertical cross-sectional view along the vertical direction, as shown in Figure 2, and linearly in a horizontal cross-sectional view along the radial direction, as shown in Figure 3.

[0026] In each grip recess 15, a lower finger rest recess 22 is formed on the bottom surface 16, directly below the upper finger rest recess 21. The depth of the lower finger rest recess 22 is shallower than the depth of the upper finger rest recess 21. When viewed from the left or right, the lower finger rest recess 22 has a long rectangular shape in the front-to-back direction. The lower finger rest recess 22 is slightly below the upper finger rest recess 21. The bottom surface of the lower finger rest recess 22 extends linearly in a vertical cross-sectional view along the vertical direction, as shown in Figure 2, and linearly in a horizontal cross-sectional view along the radial direction, as shown in Figure 3.

[0027] As shown in Figures 1 and 2, a constricted portion 23 is formed on the rear portion 18b of the rear wall surface 18, adjacent in the front-rear direction to the upper finger rest recess 21, opening into the back region 13b and narrowing the width of the back region 13b in the left-right direction. The vertical positions of the constricted portion 23 and the upper finger rest recess 21 are the same. The constricted portion 23 is formed over the entire front-rear area of ​​the rear portion 18b of the rear wall surface 18. When viewed from the rear, the constricted portion 23 has a curved shape that is recessed inward in the left-right direction. The bottom surface of the constricted portion 23 is located outward in the left-right direction from the bottom surface of the upper finger rest recess 21.

[0028] A single recess 24 is formed on the bottom surface of the constricted portion 23, and multiple recesses 24 are formed at vertical intervals in the rear portion 18b of the rear wall surface 18, located below the constricted portion 23. The depth of the recesses 24 is shallower than the depth of the constricted portion 23.

[0029] As described above, in the pinch-grip type bottle container 1 according to this embodiment, a finger rest recess 21 is formed separately at the upper end of the bottom surface 16 of each grip recess 15, and a constricted portion 23 is formed in the rear part 18b of the rear wall surface 18 in the portion adjacent to the finger rest recess 21 in the front-to-back direction, thereby narrowing the width of the back region 13b. When lifting the pinch-grip type bottle container 1, by grasping the constricted portion 23, even people with small fingers can reach the fingertips of the finger rest recesses 21 in the pair of grip recesses 15 separately while covering the back region 13b with their palm, and can firmly grip the grip portion G.

[0030] Since a lower finger rest recess 22 is separately formed on the bottom surface 16 of each grip recess 15, directly below the upper finger rest recess 21, it becomes possible to insert different fingertips into both the upper finger rest recess 21 and the lower finger rest recess 22 simultaneously when gripping the grip part G, allowing for a firm and secure grip on the grip part G.

[0031] When viewed from above or below, the back region 13b is inscribed in an arc C with a radius of curvature R2 smaller than the radius of curvature R1 of the front region 13d, thus ensuring that the width of the back region 13b is reduced.

[0032] In the torso 13, the diameter B in the front-to-back direction is larger than the diameter C in the left-to-right direction, so the width of the rear region 13b can be reliably narrowed.

[0033] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0034] For example, it is not necessary to form a lower finger rest recess 22 on the bottom surface 16 of the grip recess 15.

[0035] The synthetic resin material used to form the pinch-grip bottle-type container 1 may be changed as appropriate, for example, polyethylene terephthalate, polyethylene naphthalate, amorphous polyester, or a blend thereof. The pinch-grip type bottle container 1 is not limited to a single-layer structure, but may also be a laminated structure having an intermediate layer. Examples of this intermediate layer include a layer made of a resin material having gas barrier properties, a layer made of recycled material, or a layer made of a resin material having oxygen-absorbing properties. Furthermore, the cross-sectional shapes perpendicular to the central axis O of the shoulder portion 12, the torso portion 13, and the bottom portion 14 may be, for example, circular or angular.

[0036] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of symbols]
