Description

  The present invention relates to a bottle container.

  A bottle container that improves ease of holding has been proposed by making the cross-sectional shape of the large-capacity bottle container a substantially trapezoidal cross section (for example, Patent Document 1).

JP 2011-136746 A

  However, in the bottle container as shown in Patent Document 1, since only the central part of the bottle container has a substantially trapezoidal cross section, the gripped part is restricted to the central part of the bottle container. For this reason, it has been difficult to stably grip when the center of gravity changes as the contents decrease.

  The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide an easy-to-hold bottle container that can be stably held even when the center of gravity changes due to a decrease in contents. And

  The bottle container of the present invention has a first surface and a second surface that are opposed in the longitudinal direction of the horizontal section, and a third surface that is opposed in the short direction of the horizontal section and connects the first surface and the second surface. A maximum position at which the distance in the lateral direction of the horizontal section is maximum is a position on the first surface side from the center in the longitudinal direction of the horizontal section, and from the maximum position, the second position The distance in the short direction of the horizontal section decreases toward the surface, and the horizontal section is formed from the shoulder to the bottom.

  According to this configuration, since the maximum position where the distance in the short direction of the horizontal section is maximum is on the first surface side from the center in the longitudinal direction of the horizontal section, the palm is brought into contact with the first surface and the bottle is placed. By grasping the container, the fingers can easily reach the second surface side from the maximum position. And since the short direction distance of a horizontal section becomes small as it goes to the 2nd surface from the maximum position, the surface where a finger contacts is a slope inclined inward. Thereby, the direction of the force applied to the bottle container by fingers is inclined to the first surface side, and the gripping force acts in a direction of pressing the bottle container against the palm. Therefore, it is easy to grip the bottle container. Moreover, since the horizontal cross section as described above is formed from the shoulder portion to the bottom portion of the bottle container, it is easy to grip any position in the vertical direction. Therefore, stable gripping of the bottle container can be realized by changing the gripping position in the vertical direction of the bottle container in accordance with the gravity center position of the bottle container that changes as the contents decrease.

The third surface may be a convex curved surface.
According to this configuration, the third surface is a convex curved surface and has no inflection point. Therefore, it is easy to form the shape.

The ratio W1 / W2 between the maximum distance W1 in the short direction of the horizontal section and the distance W2 in the short direction of the horizontal section on the second surface may be 1.6 or more and 2.4 or less. Good.
According to this configuration, since the inclination of the third surface between the maximum position and the second surface with respect to the first surface is increased, the direction of the gripping force is further inclined toward the first surface side to grip the bottle container. Cheap.

The ratio W1 / W2 may be not less than 2.2 and not more than 2.4.
According to this configuration, since the inclination of the third surface between the maximum position and the second surface with respect to the first surface is increased, the direction of the gripping force is further inclined toward the first surface side to grip the bottle container. Cheap.

The ratio L1 / L2 between the distance L1 in the longitudinal direction of the horizontal section from the maximum position to the first surface and the distance L2 in the longitudinal direction of the horizontal section from the maximum position to the second surface is 0 It may be 5 or more and 0.7 or less.
According to this structure, when a palm is made to contact | abut to a 1st surface and a bottle container is hold | gripped, a finger | toe easily reaches | attains the 2nd surface side from a maximum position.

Crossing surfaces that intersect the first surface and the third surface may be formed from both the shoulder portion to the bottom portion at both ends of the horizontal cross section of the first surface. .
According to this configuration, by forming the intersecting surface, from one of the maximum positions on the third surface to the other of the maximum positions on the third surface through the first surface on the horizontal cross section. The distance to follow is shortened. Therefore, when the palm is brought into contact with the first surface and the bottle container is gripped, the fingers are more likely to reach the second surface side than the maximum position.

The intersecting surface may be a convex curved surface.
According to this configuration, it is possible to improve the adhesion between the hand and the bottle container when the bottle container is gripped. Therefore, it is easy to stably hold the bottle container.

The tangent angle formed by the first surface and the tangent parallel to the horizontal direction at the center of the cross surface in the short direction is 40 ° or more and 50 ° or less, and the distance in the short direction of the cross surface is 17 mm or more and 23.5 mm or less.
According to this configuration, it is possible to improve the adhesion between the hand and the bottle container when the bottle container is gripped. Therefore, it is easy to stably hold the bottle container.

The volume may be 500 ml or more and 1000 ml or less.
According to this configuration, it is possible to obtain a large-capacity bottle container that can be stably gripped even when the position of the center of gravity is changed due to a decrease in contents.

  According to the present invention, it is possible to obtain an easy-to-hold bottle container that can be stably held even when the center of gravity changes due to a decrease in contents.

Hereinafter, a bottle container according to an embodiment of the present invention will be described with reference to the drawings.
The scope of the present invention is not limited to the following embodiment, and can be arbitrarily changed within the scope of the technical idea of the present invention. Moreover, in the following drawings, in order to make each structure easy to understand, the actual structure may be different from the scale, number, or the like in each structure.
In the description, an XYZ coordinate system is set, and the positional relationship of each member will be described with reference to the XYZ coordinate system. At this time, the vertical direction is the Z-axis direction, the horizontal cross-section longitudinal direction of the bottle container is the Y-axis direction, and the horizontal cross-section short direction of the bottle container (the direction orthogonal to both the Y-axis direction and the Z-axis direction) is the X-axis direction. To do.

[First Embodiment]
1 and 2 are views showing a bottle container 1 according to the first embodiment.
1 is an external perspective view, FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a right side view.

The bottle container 1 of this embodiment is provided with the container main body 10 and the cap part 11, as shown to FIG.
The shape of the cap portion 11 in plan view is not particularly limited, and may be a circular shape or other shape (for example, a rectangular shape) (circular shape in the drawing).

  The container main body 10 has a horizontal cross-section (XY plane) shape that is substantially the same from the shoulder 13 to the bottom 14, and as shown in the plan view of FIG. It has a substantially trapezoidal shape surrounded by a front surface 12a and a rear surface 12b on both sides, and a right side (first surface) 10Aa and a left side surface (second surface) 10Ba on both sides in the longitudinal direction (Y-axis direction).

  The front surface 12a and the rear surface 12b have a right side portion 10A on the right side (−Y direction side) from the maximum position M1 at which the distance in the lateral direction (X-axis direction) of the horizontal section is the maximum distance W1, and the left side (+ Y) from the maximum position M1. And a left side portion 10B on the direction side). The Y-axis direction distance L1 of the right side portion 10A is smaller than the Y-axis direction distance L2 of the left side portion 10B. That is, the maximum position M1 of the distance in the lateral direction (X-axis direction) of the horizontal cross section of the container body 10 is on the right side 10Aa side from the center in the longitudinal direction (Y-axis direction). The distance L1 can be 36.8 mm, for example, and the distance L2 can be 50.7 mm, for example.

  The front surface 12a and the rear surface 12b are formed by convex curved surfaces having the maximum position M1 as a vertex. Therefore, the lateral direction distance of the horizontal cross section becomes smaller from the maximum position M1 toward the right side surface 10Aa and the left side surface 10Ba. Accordingly, the lateral direction distance W2 of the left side surface 10Ba is the minimum lateral direction distance in the left side portion 10B. The maximum distance W1 can be 71 mm, for example, and the distance W2 can be 44.4 mm, for example.

  The ratio W1 / W2 between the maximum distance W1 and the distance W2 determines the inclination of the front surface 12a and the rear surface 12b in the left side portion 10B. growing. The value of the ratio W1 / W2 can be set to 1.6, for example. The value of the ratio W1 / W2 is preferably 2.4 or less in terms of appearance as a bottle container.

  In the present specification, the substantially trapezoidal shape means a shape similar to the shape of the horizontal section having the above-described characteristics. That is, it means a shape in which W1> W2, L1 <L2, and the short-side (X-axis direction) distance decreases from the position where the maximum distance W1 is reached to the position where the distance W2 is reached.

FIG. 3 is a diagram illustrating the direction of the gripping force vector when the bottle container 1 is gripped.
As shown in FIG. 3, from the right side 10A side of the bottle container 1, the palm is brought into contact with the right side surface 10Aa to grip the bottle container 1. At this time, since the Y-axis direction distance L1 of the right side portion 10A is smaller than the Y-axis direction distance L2 of the left side portion 10B, the finger is placed on the front surface 12a on the left side surface 10Ba side (ie, the left side portion 10B) from the maximum position M1. And it is easy to make it contact | abut to the rear surface 12b. Since the gripping force is applied in a direction perpendicular to the tangential direction of the front surface 12a and the rear surface 12b at the position where the fingers come into contact, the gripping force vector comes into contact with the left side surface 10Ba from the maximum position M1. The direction is a direction inclined toward the right side surface 10Aa. Therefore, a force can be applied in the direction in which the bottle container 1 is pressed against the palm side, so that the bottle container 1 can be easily grasped.

  Moreover, according to this embodiment, since the front surface 12a and the rear surface 12b are comprised by the convex curved surface, formation of the shape of the container main body 10 is easy.

  In the present embodiment, the following configuration can also be adopted.

  The horizontal cross section of the container body 10 may be different depending on the position in the vertical direction (Z-axis direction) within a range that is substantially trapezoidal.

  The distance in the short-side direction (X-axis direction) does not have to become smaller from the maximum position M1 toward the right side surface 10Aa. For example, the short-side direction distance of the right side portion 10A can be the same as the maximum distance W1 at any position. In other words, the shape of the right side portion 10A can be a substantially rectangular parallelepiped.

  The maximum position M1 may be the position of the right side surface 10Aa. In this case, the short direction (X-axis direction) distance decreases from the right side surface 10Aa toward the left side surface 10Ba.

[Second Embodiment]
Next, a description will be given of a second embodiment in which chamfered surfaces are formed at both ends of the right side surface in the lateral direction.
In addition, about the component similar to the said embodiment, the code | symbol similar to the said embodiment is attached | subjected suitably, and the description is simplified or abbreviate | omitted.

4 and 5 are views showing the bottle container 2 of the second embodiment.
4 is an external perspective view, FIG. 5A is a plan view, FIG. 5B is a front view, and FIG. 5C is a right side view.
The bottle container 2 of this embodiment is provided with the container main body 20 and the cap part 11, as shown to FIG.

Similar to the container body 10 of the first embodiment, the container body 20 has a horizontal cross-section (XY plane) shape that is substantially the same from the shoulder 23 to the bottom 24, and is shown in the plan view of FIG. As shown, it is substantially trapezoidal.
The container body 20 includes a right side portion 20A from the maximum position M2 to the right side surface 20Aa where the distance in the short side direction (X-axis direction) is maximum, and a left side portion 20B from the maximum position M2 to the left side surface 20Ba. Yes. The front surface 25a and the rear surface 25b that connect the right side surface 10Aa and the left side surface 10Ba are convex curved surfaces.

  Chamfered surfaces (intersection surfaces) 22 that intersect the right side surface 20Aa, the front surface 25a, and the rear surface 25b are formed at both ends of the right side surface 20Aa in the short direction (X-axis direction). The chamfered surfaces 22 are respectively formed from the shoulder portion 23 to the bottom portion 24, and are gently convex curved surfaces. The angle θ2 and the lateral direction distance L3 formed by the tangent at the center in the lateral direction of the chamfered surface 22 shown in FIG. 5A and the right side surface 20Aa can be determined according to the shape of the hand to be gripped. For example, the angle θ2 can be 40 ° or more and 50 ° or less, and the distance L3 can be 17 mm or more and 23.5 mm or less.

  According to the bottle container 2 of the present embodiment, since the chamfered surface 22 is provided, the maximum position M2 of the rear surface 25b from the maximum position M2 of the front surface 25a to the outer periphery of the bottle container 2 via the right side surface 20Aa. The distance to be traced becomes shorter. Therefore, when the palm is brought into contact with the right side surface 20Aa and the bottle container 2 is gripped, the fingers are more likely to come into contact with the left side surface 20Ba side than the maximum position M2. Therefore, the gripping force vector by the fingers can be more reliably set in the direction in which the bottle container is pressed against the palm side, so that it is easy to grip.

Further, since the chamfered surface 22 is a gently convex curved surface, when gripped, the adhesion between the palm and fingers and the bottle container 2 can be improved, and the grip can be stably gripped.
When the angle θ2 and the distance L3 on the chamfered surface 22 are the values exemplified above (the angle θ2 is 40 ° or more and 50 ° or less, and the distance L3 is 17 mm or more and 23.5 mm or less), the bottle container 2 is gripped. In this case, suitable adhesion can be obtained.

  In the present embodiment, the following configuration can also be adopted.

  The chamfered surface 22 may not be a convex curved surface. For example, it may be a flat surface or a concave curved surface.

The bottle containers of the first embodiment and the second embodiment, which are described in detail above, are more suitably effective when applied to bottle containers having a volume of 500 ml or more and 1000 ml or less.
Needless to say, the present invention can be applied to bottle containers having other volumes.

[Example]
Next, a description will be given of the ease-of-holding verification test performed for a plurality of examples having different parameters.
Table 1 is a table showing evaluation of each parameter, gripping force vector angle θ1, and ease of holding in the comparative example and Examples 1 to 6.

  As shown in Table 1, as an example, the values of parameters W1, W2, L1, and L2 and the presence or absence of a chamfered surface shown in FIG. As a comparative example, a bottle container having a horizontal cross section symmetrical with respect to a position where the values of L1 and L2 are equal and the lateral direction distance is the maximum value W1 was used.

  Examples 1, 3, and 5 are the bottle containers of the first embodiment, and Examples 2, 4, and 6 are the bottle containers of the second embodiment. Example 1 and Example 2, Example 3 and Example 4, Example 5 and Example 6 differ only in the presence or absence of chamfered surfaces, and the values of the parameters W1, W2, L1, and L2 are the same. . In Examples 1, 3, and 5 and Examples 2, 4, and 6, the value of W2 is changed on the basis of the value of W1, and the value of the ratio W1 / W2 between W1 and W2 increases in order. Is set. Accordingly, the value of the ratio L1 / L2 between L1 and L2 is set so as to decrease in order.

  A test subject having an average hand length of an adult male held the comparative example and Examples 1 to 6 as shown in FIG. 2, and marking was performed at the position where the finger touched. Marking is performed for each of the contact position P1 of the middle finger and the contact position P2 of the thumb. The normal line of the tangent line T (direction of the gripping force vector Vg) at the contact position P2, the contact position P1, and the contact position. The angle formed by the line connecting P2 was defined as the gripping force vector angle θ1. The larger the value of the gripping force vector angle θ1, the easier it is to grip because the force increases in the direction in which the bottle container is pressed against the palm side (right side 10Aa side).

The evaluation of ease of holding was performed as follows according to the value of the gripping force vector angle θ1.
θ1 ≦ 0 ° ・ ・ ・ very difficult to hold (×)
0 ° <θ1 <8 ° ・ ・ ・ Hard to hold (△)
8 ° ≦ θ1 <12 ° ・ ・ ・ Easy to hold (○)
12 ° ≦ θ1 ... very easy to hold (◎)

  From Table 1, the gripping force vector angle θ1 in the comparative example is 4.7 °, which is difficult to hold (Δ), whereas the gripping force vector angles θ1 in Examples 1 to 6 are all 8 ° or more. Yes, it is easy to hold (○, ◎). Thereby, according to the present Example, it was confirmed that the bottle container easy to hold was obtained. The gripping force vector angle θ1 shown in Table 1 is an average value of three measurement data.

It can also be seen that if the ratio W1 / W2 is 1.6 or more, it is easy to hold (◯), and if it is 2.2 or more, it is very easy to hold (持 ち).
It can also be seen that if the ratio L1 / L2 between L1 and L2 is 0.7 or less, it is easy to hold (◯), and if it is 0.5 or less, it is very easy to hold (（).

FIG. 6 is a bar graph showing the gripping force vector angle θ1 shown in Table 1.
As shown in FIG. 6, when Example 1 and Example 2, Example 3 and Example 4, Example 5 and Example 6 are compared, Example 2 and Example 4 provided with chamfered surfaces are compared. In addition, it can be seen that the value of the gripping force vector angle θ1 is larger in Example 6 and gripping is easier. Thereby, the improvement effect of the ease of holding by providing a chamfering surface was confirmed.
