Therefore, it is possible to grip the grip part such that the fingertip is hooked in the finger-holding recess while the palm part is placed on the grip part.

JP, 2013-133155, A

However, in the conventional bottle-type container described above, when the hand is small, it is difficult for the fingertip to reach the finger-holding concave portion, and the finger-tip entering the finger-holding concave portion is likely to be shallow. Therefore, the fingertip cannot be sufficiently hooked in the finger-holding concave portion, and it may be difficult to grip the grip portion.

The present invention has been made in view of the above circumstances, and an object thereof is a pinch grip type bottle type that can stably grip a grip portion without being affected by the size of a hand. Is to provide a container.

(1) In the bottle-type container according to the present invention, a mouth portion, a shoulder portion, a body portion, and a bottom portion are continuously provided along a bottle axis, and the side surfaces of the body portion that face each other with the bottle axis interposed therebetween in the radial direction. A pinch-grip-type bottle-shaped container in which finger-holding recesses are respectively formed in the region, and in the body, the entire region located between the pair of finger-holding recesses including the back region of the body is , A grip portion extending along the bottle axial direction, and the grip portion includes an upper grip portion having a predetermined grip width in the left-right direction in which the pair of finger-holding recesses face each other, and an upper grip portion of the upper grip portion. disposed below, example Bei and a short lower grip than the grip width in the lateral direction is the upper grip portion, the upper gripping part and the lower grip portion, along the circumferential direction of the barrel in the rear region And a pair of second grip wall portions that connect the peripheral end portion of the first grip wall portion and the inner wall surface of the finger-holding recess to each other. A step portion facing downward is formed between the second grip wall portion and the second grip wall portion of the lower grip portion .

According to the bottle type container of the present invention, since the grip widths of the upper grip portion and the lower grip portion are different, the gripping position can be selected according to the size of the hand.
For example, when the hand is small, by grasping the lower grip portion having a short grip width, the fingertip can reach the finger-holding recess with a margin. Therefore, the fingertip can easily enter deep into the finger-holding recess, and the finger-tip can be sufficiently hooked in the finger-holding recess. At this time, the bottle-shaped container can be supported by, for example, applying a finger pad portion from below to a step portion formed between the upper grip portion and the lower grip portion and facing downward. For these reasons, the lower grip portion can be firmly gripped, and the bottle type container can be carried around stably.

When the hand is large, by gripping the upper grip portion, the upper grip portion can be strongly gripped as in the case described above. At this time, not only the upper grip portion but also the upper grip portion and the lower grip portion can be grasped together. For example, it is possible to grasp the upper grip portion with the index finger and the middle finger, and grasp the lower grip portion with the ring finger and the little finger. In this case, of the inner wall surfaces that define the finger-holding concave portion, the index finger is hooked on the upper inner wall surface that is located on the upper side and faces downward, and the step portion between the upper grip portion and the lower grip portion is Since it is possible to hook the ring finger, it is possible to carry the bottle type container more stably and reliably.

As described above, since the upper grip portion and the lower grip portion can be selectively gripped according to the size of the hand, the grip portion can be stably and reliably gripped without being affected by the size of the hand. You can

(2) The grip length of the lower grip portion along the bottle axial direction may be longer than the grip length of the upper grip portion along the bottle axial direction.

In this case, the lower grip portion can be easily arranged closer to the mouth portion of the bottle-shaped container, so that the lower grip portion can be prevented from being unevenly arranged on the bottom side of the bottle-shaped container. Therefore, when the lower grip portion is gripped, it is easy to prevent the bottle-shaped container from becoming unstable due to, for example, wobbling. Further, since the lower grip portion can be arranged near the mouth of the bottle-shaped container, it is easy to maintain the posture of the bottle-shaped container stable when pouring the contents through the mouth.

(3) The grip width of the upper grip portion may be in the range of 50 mm to 80 mm, and the grip width of the lower grip portion may be in the range of 40 mm to 70 mm.

In this case, for example, it can be suitably used as a large-capacity bottle-type container having an internal volume of 2.7 liters, 4 liters, or the like.

According to the bottle-type container of the present invention, the upper grip portion and the lower grip portion can be selected and gripped according to the size of the hand, so that the grip portion can be stabilized without being affected by the size of the hand. In addition, it can be reliably gripped.

Hereinafter, an embodiment of a bottle type container concerning the present invention is described with reference to drawings.
As shown in FIGS. 1 to 4, the bottle-type container 1 of the present embodiment has a pinch grip in which a mouth portion 2, a shoulder portion 3, a body portion 4 and a bottom portion 5 are continuously arranged along the bottle axis O in this order. It is a synthetic resin bottle of the formula.
Hereinafter, along the bottle axis O direction, the mouth portion 2 side is referred to as the upper side and the bottom portion 5 side is referred to as the lower side. In a plan view seen from the direction of the bottle axis O, the direction orthogonal to the bottle axis O is called the radial direction, and the direction that goes around the bottle axis O is called the circumferential direction.

The bottle-type container 1 is formed by blow molding including, for example, extrusion blow molding using a parison and biaxial stretch blow molding using a preform formed into a bottomed tubular shape. The internal volume of the bottle-type container 1 is not limited to a specific volume, and may be a large volume such as 2.7 liters or 4 liters or a small volume such as 1.8 liters or 1 liter or less. Absent.

Examples of the synthetic resin include polyethylene terephthalate (PET), polyethylene naphthalate, amorphous polyester and the like, and blend materials of these. However, the bottle type container 1 of the present embodiment is not limited to the case of being formed of one kind of synthetic resin, and may be formed by laminating different kinds of synthetic resins.
For example, the bottle-shaped container 1 may be formed by laminating two kinds of synthetic resins, a main resin and a barrier resin. In this case, examples of the main resin include the above-mentioned resins such as PET. In addition, the barrier resin has a barrier property that restricts, for example, gas (oxygen, carbon dioxide, etc.), moisture such as humidity, light such as ultraviolet rays, and odor components such as scents from passing through the main resin. The resin is a resin that is appropriately selected according to the object to be barriered. For example, when a barrier property against gas is exhibited, a nylon resin, an ethylene vinyl alcohol copolymer resin or the like is used, and when a barrier property against water is exhibited, a cyclic polyolefin resin or the like is included.

The shoulder portion 3 is formed so as to gradually reduce its diameter from the upper end portion of the body portion 4 toward the upper side. The mouth portion 2 extends upward from the upper end portion of the shoulder portion 3. On the outer peripheral surface of the mouth portion 2, a screw portion 2a to which a cap (not shown) is screwed is formed. However, the present invention is not limited to the screw portion 2a, and for example, a fitting protrusion for undercut fitting the cap may be formed on the outer peripheral surface of the mouth portion 2.

In the body portion 4, a pair of finger-holding recesses 10 are formed in side surface regions E1 facing each other with the bottle axis O interposed therebetween in the radial direction. The grip portion 20 is the entire region of the body portion 4 that is located between the pair of finger-holding recesses 10 including the back surface region E2 of the body portion 4.

In the body portion 4, a region located on the opposite side to the back face region E2 in the radial direction with the bottle axis O interposed therebetween is referred to as a front face region E3. In the radial direction, the direction in which the pair of finger-holding recesses 10 face each other is referred to as the left-right direction L1, and the direction connecting the back surface area E2 and the front area E3 is referred to as the front-back direction L2 orthogonal to the left-right direction L1. Further, the back surface region E2 side along the front-rear direction L2 is referred to as the rear side, and the front surface region E3 side is referred to as the front side.

The finger-holding recess 10 is formed so as to be recessed inward of the container along the left-right direction L1 as shown in FIGS. 1, 3, 5, and 6. In the illustrated example, the finger-holding concave portion 10 is arranged so as to be positioned slightly above the central portion of the bottle type container 1 in the bottle axis O direction, and is arranged in the bottle axis O direction in a side view as seen from the side surface region E1 side. It is formed in a long vertically long rectangular shape.

The finger-holding concave portion 10 is defined by a bottom surface 11 and four inner wall surfaces that rise from the outer peripheral edge portion of the bottom surface 11 toward the outside of the container. Among the four inner wall surfaces, the inner wall surface that faces downward is the upper inner wall surface 12, the inner wall surface that faces upward is the lower inner wall surface 13, and the inner wall surface that faces rearward is the front inner wall surface 14, and the inner wall surface that faces forward. The wall surface is the rear inner wall surface 15.

The bottom surfaces 11 of the pair of finger-holding recesses 10 are arranged to face each other in the left-right direction L1. In the illustrated example, the bottom surface 11 is arranged in parallel along the front-rear direction L2, but the invention is not limited to this case. The upper inner wall surface 12 and the lower inner wall surface 13 are inclined so as to gradually separate from each other from the bottom surface 11 toward the outside of the container. The rear inner wall surface 15 and the front inner wall surface 14 are inclined so as to gradually separate from each other from the bottom surface 11 toward the outside of the container.

In the side surface area E1 of the body portion 4, a connection wall portion 30 is formed that gradually extends toward the outside of the container as the distance from the outer peripheral edge portion of the finger-holding recess 10 increases. The connecting wall portion 30 is arranged so as to surround the upper inner wall surface 12, the lower inner wall surface 13, and the front inner wall surface 14 from above, below, and from the front, respectively.

The upper side wall portion 31 of the connecting wall portion 30 located above the upper inner wall surface 12 is gradually inclined upward as it goes from the upper end of the upper inner wall surface 12 toward the outside of the container. The lower side wall portion 32 of the connecting wall portion 30, which is located below the lower inner wall surface 13, gradually inclines downward from the lower end portion of the lower inner wall surface 13 toward the outside of the container. Further, the front wall portion 33 of the connecting wall portion 30, which is located in front of the front inner wall surface 14, is gradually inclined forward as it goes from the front end portion of the front inner wall surface 14 toward the outside of the container.

The grip portion 20 is formed vertically long along the bottle axis O direction so as to correspond to the pair of fingerhold recesses 10. The grip portion 20 forms a part of the body portion 4 in the back surface region E2, and extends along the circumferential direction, a first grip wall portion 21, a peripheral end portion of the first grip wall portion 21, and a pair of fingers. It is provided with a pair of second grip wall portions 22 that connect the rear end portion of the rear inner wall surface 15 of the recess 10 for use.

As shown in FIGS. 5 and 6, the pair of second grip wall portions 22 are arranged to face each other in the left-right direction L1. The second grip wall portion 22 extends rearward from the rear end portion of the rear inner wall surface 15 along the front-rear direction L2, and then smoothly connects to the peripheral end portion of the first grip wall portion 21 while curving. Has been done.

As shown in FIGS. 1, 3, 5, and 6, the grip portion 20 of this embodiment includes an upper grip portion 25 and a lower grip portion 26 having different grip widths along the left-right direction L1.
The upper grip portion 25 is arranged on the mouth portion 2 side of the grip portion 20 and has a predetermined grip width W1. The lower grip portion 26 is disposed below the upper grip portion 25 and has a grip width W2 shorter than the grip width W1 of the upper grip portion 25.

In this way, since the grip width W2 of the lower grip portion 26 is shorter than the grip width W1 of the upper grip portion 25, a step portion 27 facing downward is formed between the upper grip portion 25 and the lower grip portion 26. ing.
In the illustrated example, the step portion 27 is formed between the second grip wall portion 22 of the upper grip portion 25 and the second grip wall portion 22 of the lower grip portion 26. At this time, the step portion 27 extends from the lower end portion of the second grip wall portion 22 of the upper grip portion 25 along the left-right direction L1 and gradually lowers toward the upper end portion of the second grip wall portion 22 of the lower grip portion 26. It is inclined so as to extend toward. However, the step portion 27 is not limited to the case of being inclined, and may be formed so as to be orthogonal to the bottle axis O.

Further, the lower grip portion 26 is formed such that the grip length H2 along the bottle axis O direction is longer than the grip length H1 of the upper grip portion 25 along the bottle axis O direction. In the illustrated example, the grip length H2 of the lower grip portion 26 is about twice the grip length H1 of the upper grip portion 25.

However, the grip lengths of the upper grip portion 25 and the lower grip portion 26 are not limited to the above-mentioned ratios and may be changed as appropriate.
For example, the grip length H2 of the lower grip portion 26 may be three times or more longer than the grip length H1 of the upper grip portion 25. Furthermore, the grip length H2 of the lower grip portion 26 may be shorter than the grip length H1 of the upper grip portion 25, or may be the same length.

As shown in FIGS. 1 to 4, the bottle-shaped container 1 includes a plurality of reduced pressure absorption panels for suppressing or preventing deformation due to reduced pressure in the container, a plurality of concave ribs for increasing rigidity, and a concave portion. A groove is formed.

Specifically, the first annular groove 40 is continuously formed over the entire circumference at the connecting portion between the shoulder portion 3 and the body portion 4. In addition, a second annular groove 41 is continuously formed over the entire circumference at the connecting portion between the body portion 4 and the bottom portion 5.

A plurality of first decompression absorption panel portions 42 are formed on the shoulder portion 3 at intervals in the circumferential direction. The first decompression absorption panel portion 42 is formed along the outer peripheral surface of the shoulder portion 3 in a fan shape in which the length in the circumferential direction gradually increases from the upper side to the lower side. In the illustrated example, the upper end portion of the first depressurization absorption panel portion 42 is formed in a curved shape protruding upward, and the lower end portion is formed in a curved shape protruding downward.
The shape and the number of the first decompression absorption panel sections 42 are not limited to those described above, and may be changed as appropriate.

A second decompression absorption panel portion 43 is formed in a portion of the body portion 4 which is located below the pair of finger-holding concave portions 10. The second reduced pressure absorption panel portion 43 is formed in a substantially rectangular shape that is longer in the front-rear direction L2 than in the bottle axis O direction when viewed from the side surface region E1 side.
The upper end of the second depressurized absorption panel section 43 is connected to the lower end of the lower inner wall surface 13 of the finger-holding recess 10 via the lower side wall section 32 of the connecting wall section 30 described above.

A third decompression absorption panel portion 44 is formed in a portion of the body portion 4 located below the grip portion 20 in the back surface area E2. The third decompression absorption panel portion 44 is formed in a rectangular shape that is longer in the bottle axis O direction than in the left-right direction L1 when viewed from the rear surface area E2 side. The upper end portion of the third decompression absorption panel portion 44 is formed such that its length in the circumferential direction gradually becomes shorter as it goes upward.
In addition, the above-mentioned 2nd pressure reduction absorption panel part 43 is settled in the height range between the center part in the bottle axis O direction in the 3rd pressure reduction absorption panel part 44, and the lower end part in the 3rd pressure reduction absorption panel part 44. Are arranged as follows.

A first circumferential groove 45 extending along the circumferential direction is formed in a portion of the body portion 4 located between the second reduced pressure absorption panel portion 43 and the second annular recessed groove 41. The first circumferential groove 45 is formed over the pair of side surface regions E1 and front region E3, and the circumferential end portion thereof is located below the second reduced pressure absorption panel portion 43.

In the front area E3 of the body portion 4, a second circumferential groove 46 extending in the circumferential direction is formed. In the illustrated example, the second circumferential groove 46 has a length that does not reach the connecting wall portion 30, and a plurality of second circumferential grooves 46 are formed at intervals in the bottle axis O direction.
A third circumferential groove 47 extending in the circumferential direction is formed on the first grip wall portion 21. In the illustrated example, a plurality of third circumferential grooves 47 are formed at intervals in the bottle axis O direction. The third circumferential groove 47 may or may not reach the second grip wall portion 22.
A concave rib 48 extending in the radial direction is formed on the bottom portion 5. In the illustrated example, a plurality of concave ribs 48 are formed at intervals in the circumferential direction, and are arranged radially around the bottle axis O, for example.

(Function of bottle type container)
Next, the case of using the bottle-type container 1 configured as described above will be described.
In the bottle-type container 1 of the present embodiment, since the grip widths of the upper grip portion 25 and the lower grip portion 26 are different, the gripping position can be selected according to the size of the hand.

For example, for a person with a small hand, the lower grip portion 26 having a short grip width W2 can be selected.
In this case, since the grip width W2 is short when the lower grip portion 26 is gripped, it is possible to allow the fingertip to reach the finger contact recess 10 with a margin. Therefore, the fingertip can easily be deeply inserted into the finger-holding recess 10, and the finger-tip can be sufficiently hooked on the finger-holding recess 10. Further, the bottle-shaped container 1 can be supported by applying the part of the finger pad from below to the step portion 27 formed between the upper grip portion 25 and the lower grip portion 26 so as to face downward. .. For these reasons, even a person with a small hand can firmly grip the lower grip portion 26, and can stably lift and carry the bottle type container 1.

On the other hand, for a person with a large hand, the upper grip portion 25 having a long grip width W1 can be selected, and the upper grip portion 25 can be strongly gripped as in the case described above.
For a person with a large hand, not only the upper grip 25 but also both the upper grip 25 and the lower grip 26 may be gripped. For example, the upper grip portion 25 may be gripped by the index finger and the middle finger, and the lower grip portion 26 may be gripped by the ring finger and the little finger. In this case, the index finger is hooked from below on the upper inner wall surface 12 of the finger-holding recess 10 and the ring finger is hooked from below onto the step 27 between the upper grip 25 and the lower grip 26. Therefore, the bottle-shaped container 1 can be carried more stably and reliably.

As described above, according to the bottle-type container 1 of the present embodiment, the upper grip portion 25 and the lower grip portion 26 can be selected and gripped according to the size of the hand, so that the size of the hand is affected. The grip portion 20 can be stably and surely gripped without moving.

Further, in the present embodiment, since the grip length H2 of the lower grip portion 26 is longer than the grip length H1 of the upper grip portion 25, the lower grip portion 26 is biased toward the bottom 5 side of the bottle-shaped container 1. It can be suppressed. Therefore, when the lower grip portion 26 is gripped, it is easy to prevent the bottle-shaped container 1 from wobbling and becoming unstable.
Further, since the lower grip portion 26 can be arranged near the mouth portion 2 of the bottle type container 1, it is easy to maintain a stable posture of the bottle type container 1 when pouring out contents through the mouth portion 2, for example. Therefore, for example, even a child or a woman with small hands can easily pour out the contents.

The depth of the finger-holding concave portion 10 is not particularly limited, but when the finger-holding concave portion 10 is formed deep, the fingertip is held inside the finger-holding concave portion 10 when the lower grip portion 26 is gripped. Since it is possible to sufficiently enter the above, it is possible to further exert the above-described effects.
The depth of the finger-holding concave portion 10 is, for example, a rear view as seen from the back surface region E2, and a distance along the left-right direction L1 between the bottom surfaces 11 of the pair of finger-holding concave portions 10 is the lower grip portion. It is preferable to form the grip width W2 of 26 by 10 mm or more. That is, it is preferable to form the finger-holding recesses 10 so as to be recessed by 5 mm or more in the left-right direction L1 from the front end portion of the second grip wall portion 22 of the grip portion 20.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above embodiment, the grip width and the grip length of the upper grip portion 25 and the lower grip portion 26 are not particularly limited, and may be appropriately changed depending on, for example, the internal capacity.
For example, the grip width W1 of the upper grip portion 25 is within the range of 50 mm to 80 mm, and the grip width W2 of the lower grip portion 26 is shorter than the grip width W1 of the upper grip portion 25 and within the range of 40 mm to 70 mm. As a result, it can be used as a large-capacity bottle-type container 1 having an internal capacity of 2.7 liters, 4 liters, or the like. In this case, it is more preferable that the grip length of the entire grip portion 20 is 60 mm or more and the grip length H1 of the upper grip portion 25 is 30 mm or more.

Further, in the above-described embodiment, the grip width is changed in two steps, but for example, the lower grip portion 26 has a first lower grip portion having a grip width shorter than that of the upper grip portion 25, and a further lower than the first lower grip portion. A second lower grip portion having a short grip width may be included, and the grip width may be changed in three steps, such as in three steps.

Further, in the above embodiment, the cross-sectional view shape of the body portion 4 may be freely changed. For example, in a cross-sectional view of the body 4, a first distance A1 from the bottle axis O to the back surface area E2 along the front-rear direction L2 (radial direction) and a front area E3 from the bottle axis O along the front-rear direction L2. It is preferable that the body portion 4 is formed so that the relationship between the first distance A1 and the second distance B1 is (first distance A1=second distance B1) or (first distance A1<second distance B1). ..
