特許第４２０９２９６号公報Patent No. 4209296

ピンチグリップ式ボトル型容器では、胴部の直径が大きくなると、背面領域の周方向の大きさである幅が広くなり、手指の小さい人ではグリップ部を強く握ることができなくなる場合がある。 In a pinch-grip bottle-type container, as the diameter of the body increases, the circumferential width of the back area increases, and people with small fingers may not be able to grip the grip firmly.

本発明は、手指の小さい人でもグリップ部を強く握ることができるピンチグリップ式ボトル型容器を提供することを目的の一つとする。 One of the objects of the present invention is to provide a pinch-grip bottle-shaped container that allows even people with small fingers to firmly grasp the grip portion.

本発明の一態様に係るピンチグリップ式ボトル型容器は、胴部において、口部の中心軸線を径方向のうちの左右方向に挟んで互いに対向する一対の側面領域に、グリップ凹部が各別に形成されるとともに、前記一対の側面領域同士の間に位置する背面領域、および前記グリップ凹部がグリップ部とされ、前記グリップ凹部は、左右方向を向く底面と、前記底面の外周縁から左右方向に立ち上がる側壁面と、を備え、前記側壁面は、前記グリップ凹部における前記背面領域側の後端部を画成する後側壁面を備え、前記後側壁面のうちの前記背面領域に連なる後部は、左右方向を向き、それぞれの前記グリップ凹部の底面における上端部に、上指当て用凹部が各別に形成され、前記後側壁面の後部において、前記上指当て用凹部に対して、径方向のうちの左右方向に直交する前後方向に隣接する部分には、前記背面領域に開口して、前記背面領域の左右方向の大きさである幅を狭めるくびれ部が形成されている。 In the pinch-grip bottle-shaped container according to one aspect of the present invention, grip recesses are formed separately in a pair of side areas of the body that face each other across the center axis of the mouth in the left and right directions in the radial direction. and a back area located between the pair of side areas and the grip recess are used as a grip part, and the grip recess has a bottom face facing in the left-right direction and rising up in the left-right direction from an outer peripheral edge of the bottom face. a side wall surface, the side wall surface includes a rear wall surface defining a rear end portion of the grip recess on the rear surface region side, and a rear portion of the rear wall surface that is continuous with the rear surface region is arranged on the left and right sides. An upper finger rest recess is formed separately at the upper end of the bottom surface of each of the grip recesses, and at the rear part of the rear wall surface, the upper finger rest recess is formed in the radial direction with respect to the upper finger rest recess. A constricted portion that opens into the back area and narrows the width of the back area in the left and right direction is formed in a portion adjacent in the front-back direction perpendicular to the left-right direction.

それぞれのグリップ凹部の底面における上端部に、上指当て用凹部が各別に形成され、後側壁面の後部において、上指当て用凹部に対して前後方向で隣接する部分に、背面領域の幅を狭めるくびれ部が形成されているので、ピンチグリップ式ボトル型容器を持ち上げる際、くびれ部を掴むことで、手指の小さい人でも、背面領域を手のひらで覆いながら、一対のグリップ凹部における上指当て用凹部に指先を各別に到達させることが可能になり、グリップ部を強く握ることができる。 An upper finger rest recess is formed separately at the upper end of the bottom surface of each grip recess, and a width of the back area is formed at the rear part of the rear wall surface adjacent to the upper finger rest recess in the front and back direction. A narrow constriction is formed, so even people with small hands can cover the back area with their palms and place their upper fingers on the pair of grip recesses by grasping the constriction when lifting a pinch-grip bottle-type container. It becomes possible to reach each of the recesses with the fingertips separately, and the grip part can be gripped firmly.

それぞれの前記グリップ凹部の底面において、前記上指当て用凹部の直下に位置する部分に、下指当て用凹部が各別に形成されてもよい。 On the bottom surface of each of the grip recesses, a lower finger rest recess may be separately formed in a portion located directly below the upper finger rest recess.

それぞれのグリップ凹部の底面において、上指当て用凹部の直下に位置する部分に、下指当て用凹部が各別に形成されているので、グリップ部を把持するときに、上指当て用凹部および下指当て用凹部の双方に同時に異なる指先を差し込むことが可能になり、グリップ部を確実に強く握ることができる。 On the bottom surface of each grip recess, a lower finger rest recess is formed in a portion located directly below the upper finger rest recess, so when gripping the grip, the upper finger rest recess and the lower finger rest recess are formed separately. It becomes possible to insert different fingertips into both of the finger rest recesses at the same time, and the grip part can be reliably and strongly gripped.

上下方向から見て、前記背面領域は、前記胴部のうち、前記中心軸線を径方向に挟む前記背面領域の反対側に位置する正面領域の曲率半径より小さい曲率半径の円弧に内接してもよい。 When viewed from above and below, the back area may be inscribed in an arc having a radius of curvature smaller than a radius of curvature of a front area located on the opposite side of the back area across the central axis in the radial direction of the body. good.

上下方向から見て、背面領域が、正面領域の曲率半径より小さい曲率半径の円弧に内接しているので、背面領域の幅を確実に狭めることができる。 Since the back area is inscribed in a circular arc with a radius of curvature smaller than the radius of curvature of the front area when viewed from the top and bottom, the width of the back area can be reliably narrowed.

前記胴部において、径方向のうち、前記背面領域および前記正面領域が互いに対向する前後方向の直径が、一対の前記側面領域が互いに対向する左右方向の直径より大きくなってもよい。 In the trunk, a diameter in a radial direction in the front-back direction where the back area and the front area face each other may be larger than a diameter in the left-right direction where the pair of side areas face each other.

胴部において、前後方向の直径が、左右方向の直径より大きくなっているので、背面領域の幅を確実に狭めることができる。 In the trunk, the diameter in the front-rear direction is larger than the diameter in the left-right direction, so the width of the back area can be reliably narrowed.

以下、図面を参照し、一実施形態に係るピンチグリップ式ボトル型容器を説明する。
本実施形態に係るピンチグリップ式ボトル型容器１は、図１および図２に示されるように、口部１１、肩部１２、胴部１３および底部１４を備え、これら１１～１４が、口部１１の中心軸線Ｏに沿ってこの順に連設された概略構成となっている。
ピンチグリップ式ボトル型容器１の内容積は、例えば２００ｍｌ以上４０００ｍｌ以下の内容物が充填される大きさとなっている。図示の例では、ピンチグリップ式ボトル型容器１は、約２２００ｍｌの内容物が充填されるのに用いられる大きさとなっている。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A pinch-grip bottle-type container according to an embodiment will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, the pinch-grip bottle-shaped container 1 according to the present embodiment includes a mouth portion 11, a shoulder portion 12, a body portion 13, and a bottom portion 14, and these 11 to 14 form the mouth portion. 11 are arranged in series in this order along the central axis O.
The inner volume of the pinch-grip bottle-shaped container 1 is such that it can be filled with, for example, 200 ml or more and 4000 ml or less. In the illustrated example, the pinch-grip bottle-type container 1 is sized to be filled with approximately 2200 ml of contents.

以下、口部１１の中心軸線Ｏに沿って、口部１１側を上側、底部１４側を下側といい、中心軸線Ｏに沿う方向を上下方向といい、また、上下方向から見て、中心軸線Ｏに交差する方向を径方向、中心軸線Ｏ回りに周回する方向を周方向という。
なお、ピンチグリップ式ボトル型容器１は、射出成形により有底筒状に形成されたプリフォームが、ブロー成形されて形成され、合成樹脂材料で一体に形成されている。口部１１には、図示しないキャップが装着される。 Hereinafter, along the central axis O of the mouth 11, the mouth 11 side will be referred to as the upper side, the bottom 14 side will be referred to as the lower side, and the direction along the central axis O will be referred to as the vertical direction. The direction that intersects the axis O is called the radial direction, and the direction that goes around the center axis O is called the circumferential direction.
The pinch-grip bottle-shaped container 1 is formed by blow-molding a preform formed into a bottomed cylindrical shape by injection molding, and is integrally formed from a synthetic resin material. A cap (not shown) is attached to the mouth portion 11.

胴部１３のうち、中心軸線Ｏを径方向に挟んで互いに対向する一対の側面領域１３ａに、グリップ凹部１５が各別に形成されている。胴部１３のうち、一対の側面領域１３ａ同士の間に位置する背面領域１３ｂ、およびグリップ凹部１５が、使用者がピンチグリップ式ボトル型容器１を持ち上げる際に把持するグリップ部Ｇとなっている。グリップ凹部１５およびグリップ部Ｇは、胴部１３のうち、上端部と下端部との間に位置する中間部に設けられている。胴部１３の上端部および下端部には、周方向の全長にわたって連続して延びる周溝１３ｅが各別に形成されている。 Grip recesses 15 are separately formed in a pair of side areas 13a of the body 13 that face each other with the center axis O in the radial direction. In the body part 13, a back area 13b located between a pair of side areas 13a and a grip recess 15 serve as a grip part G that the user holds when lifting the pinch grip type bottle-shaped container 1. . The grip concave portion 15 and the grip portion G are provided in an intermediate portion of the body portion 13 located between the upper end portion and the lower end portion. A circumferential groove 13e that continuously extends over the entire length in the circumferential direction is formed at the upper end and the lower end of the body portion 13, respectively.

背面領域１３ｂは、図３に示されるように、胴部１３において、一対の側面領域１３ａ同士の間に位置する一対の領域のうち、周方向の長さが短い方となっている。背面領域１３ｂに、ピンチグリップ式ボトル型容器１内の減圧に伴う、胴部１３の復元困難な変形を防止するための減圧吸収パネル１３ｃが形成されている。 As shown in FIG. 3, the back region 13b has the shorter length in the circumferential direction of the pair of regions located between the pair of side regions 13a in the body portion 13. A vacuum absorbing panel 13c is formed on the back area 13b to prevent deformation of the body 13 that is difficult to restore due to the vacuum inside the pinch grip type bottle-shaped container 1.

以下、中心軸線Ｏに対して、背面領域１３ｂが位置している側を後側、背面領域１３ｂの反対側を前側という。胴部１３のうち、中心軸線Ｏを径方向に挟む背面領域１３ｂの反対側に位置する部分を正面領域１３ｄという。径方向のうち、背面領域１３ｂと正面領域１３ｄとが互いに対向する方向を前後方向、前後方向に直交する方向を左右方向という。 Hereinafter, with respect to the central axis O, the side on which the back area 13b is located will be referred to as the rear side, and the side opposite to the back area 13b will be referred to as the front side. A portion of the body portion 13 located on the opposite side of the back surface region 13b across the central axis O in the radial direction is referred to as a front surface 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.

肩部１２、胴部１３および底部１４それぞれにおいて、前後方向の直径が、左右方向の直径より大きくなっている。胴部１３の前後方向の直径Ｂは、胴部１３の上下方向の大きさＡの０．６倍以上１．０倍以下となっている。これにより、ピンチグリップ式ボトル型容器１の上下方向の大きさが抑えられている。ピンチグリップ式ボトル型容器１は、例えば、本容器に詰め替えるための内容物が充填される詰め替え容器として用いてもよい。
なお、肩部１２は、上方に向かうに従い径方向の内側に向けて延び、底部１４は、下方に向かうに従い径方向の内側に向けて延びている。 In each of the shoulder portion 12, body portion 13, and bottom portion 14, the diameter in the front-rear direction is larger than the diameter in the left-right direction. The diameter B of the trunk 13 in the front-rear direction is 0.6 times or more and 1.0 times or less the size A of the trunk 13 in the vertical direction. Thereby, the size of the pinch grip type bottle-shaped container 1 in the vertical direction is suppressed. The pinch-grip bottle-shaped container 1 may be used, for example, as a refill container in which the main container is filled with contents for refilling.
Note that the shoulder portion 12 extends radially inward as it goes upward, and the bottom portion 14 extends radially inward as it goes downward.

上下方向から見て、背面領域１３ｂは、正面領域１３ｄの曲率半径Ｒ１より小さい曲率半径Ｒ２の円弧Ｃに内接している。図示の例では、背面領域１３ｂのうち、周方向の両端部が、前記円弧Ｃに接し、周方向の中間部は、前記円弧Ｃより径方向の内側に位置している。上下方向から見て、前記円弧Ｃの曲率半径Ｒ２（図示の例では約５８ｍｍ）は、正面領域１３ｄの曲率半径Ｒ１（図示の例では約６６ｍｍ）の０．７倍以上１．０倍未満となっている。 When viewed from the top and bottom, the back area 13b is inscribed in an arc C having a radius of curvature R2 smaller than the radius of curvature R1 of the front area 13d. In the illustrated example, both ends of the back surface area 13b in the circumferential direction are in contact with the circular arc C, and the intermediate portion in the circumferential direction is located inside the circular arc C in the radial direction. When viewed from the top and bottom, the radius of curvature R2 (approximately 58 mm in the illustrated example) of the circular arc C is 0.7 times or more and less than 1.0 times the radius of curvature R1 (approximately 66 mm in the illustrated example) of the front area 13d. It has become.

図１および図２に示されるように、後側壁面１８の後部１８ｂにおいて、上指当て用凹部２１に対して前後方向に隣接する部分に、背面領域１３ｂに開口して、背面領域１３ｂの左右方向の大きさである幅を狭めるくびれ部２３が形成されている。くびれ部２３、および上指当て用凹部２１それぞれの上下方向の位置は、互いに同じになっている。くびれ部２３は、後側壁面１８の後部１８ｂにおける前後方向の全域にわたって形成されている。くびれ部２３は、後方から見て、左右方向の内側に向けて窪む曲線状を呈する。くびれ部２３の底面は、上指当て用凹部２１の底面より左右方向の外側に位置している。 As shown in FIGS. 1 and 2, in the rear part 18b of the rear side wall surface 18, an opening is opened into the back area 13b in a portion adjacent to the upper finger rest recess 21 in the front and back direction, and the right and left sides of the back area 13b are opened. A constricted portion 23 is formed to narrow the width, which is the size in the direction. The positions of the constricted portion 23 and the upper finger rest recess 21 in the vertical direction are the same. The constricted portion 23 is formed over the entire area of the rear portion 18b of the rear side wall surface 18 in the front-rear direction. The constricted portion 23 has a curved shape concave toward the inside in the left-right direction when viewed from the rear. The bottom surface of the constricted portion 23 is located outside the bottom surface of the upper finger rest recess 21 in the left-right direction.

くびれ部２３の底面に、窪み部２４が１つ形成され、後側壁面１８の後部１８ｂのうち、くびれ部２３より下方に位置する部分に、複数の窪み部２４が上下方向に間隔をあけて形成されている。窪み部２４の深さは、くびれ部２３の深さより浅くなっている。 One recess 24 is formed on the bottom surface of the constriction 23, and a plurality of recesses 24 are spaced apart in the vertical direction in a portion of the rear part 18b of the rear wall surface 18 located below the constriction 23.
