Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bottle container used as a container for selling beverages, liquid seasonings, liquid detergents, and the like.

[0002]

[Prior art]

As bottle containers for beverages, liquid seasonings, liquid detergents, etc., along with containers for conventional cans, paper, glass, etc., blow molded containers, so-called PET (poly (ethylene tereph)
thalate)) Bottles are spreading rapidly. PET bottles are as light and durable as cans and can be as transparent as glass bottles. Also, unlike cans, they often have lids that can be opened and closed freely, so it is very convenient not only for consumption immediately after purchase, but also for storage at home or carrying when going out.

[0003]

[Problems to be solved by the invention]

 Conventional PET bottles have a problem in that after removing, using, and drinking the original contents, the size cannot be changed while maintaining a reusable state. That is, since the PET bottle is strong and durable as described above, it is of course possible for the purchaser to reuse it personally. However, for example, when the PET bottle is purchased for carrying when going out, the PET bottle is used. Attempting to bring the bottle back in a reusable state would be bulky because the size could not be changed. The only way to reduce the size is to forcibly crush it, and it will not be possible to return it to its original shape and reuse it. Therefore, an empty PET bottle is rarely brought back for reuse after use, and is often discarded as garbage.

[0004] The invariability of the size of the conventional PET bottle causes a problem of inefficiency of collection work and transport work even when recycling and recycling. This is because when collecting the discarded PET bottles, even if they are crushed, they do not change much from the original shape and size, so that they are bulky.

[0005] In some cases, a conventional PET bottle is provided with a groove on a side surface or a bottom surface for slip prevention. The groove on the side surface may be provided in the longitudinal direction of the PET bottle, or may be provided in a ring shape in a horizontal direction. However, a grooved PET bottle is also strong as a whole, and requires considerable force to be crushed, and cannot be returned to its original shape once crushed.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a bottle container in which the volume can be easily increased or decreased or the shape can be easily changed.

[0007]

[Means for Solving the Problems]

 The bottle container according to the present invention has an opening portion for enclosing and outflowing the contents, has a stretchable structure, and has a tubular container body that is at least partially expandable and contractable along the longitudinal direction; And a lid for sealing the opening.

[0008] According to the bottle container of the present invention, since the container body is expandable and contractible, the volume and shape can be easily changed.

[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an appearance of a bottle container according to an embodiment of the present invention. The bottle container 10 is, for example, a 500-ml PET bottle used as a container for selling beverages. The bottle container 10 includes a container body 11 and a cap-shaped lid 13. The container main body 11 includes an upper end surface portion 14 curved to a substantially spherical shape or a substantially conical shape, a lower end surface portion 15 opposed to the upper end surface portion 14, and a side surface portion 16 between the upper end surface portion 14 and the lower end surface portion 15, for example, PET blown. It is formed integrally by molding. The upper end surface 14 is provided with an opening 12 for enclosing and outflow of contents such as drinking water. A male screw 12a is formed on the side surface of the opening 12 and a female screw (not shown) is formed inside the lid 13, and the inside of the container body 11 is sealed by screwing both. It has become. The configurations of the opening 12 and the lid 13 are the same as those of the related art.

In the present embodiment, a bellows structure 20 including a mountain-shaped portion 21 and a valley-shaped portion 22 is provided on the side surface 16 of the container body 11. The chevron 21 is thicker than the trough 22, and the trough 22 is folded or expanded between the chevrons 21 by applying force to the container body 11 as described later. Can be. Thus, the container body 11 can be extended and contracted along the longitudinal direction.

In the present embodiment, as shown in FIG. 1, the mountain-shaped portion 21 and the valley-shaped portion 22 are formed in a spiral shape using a straight line L connecting the centers of the upper end surface portion 14 and the lower end surface portion 15 as a spiral axis. Has been done. Since the mountain-shaped portion 21 and the valley-shaped portion 22 are formed in a spiral shape, the thickness of the mountain-shaped portion 21 and the valley-shaped portion 22 are different from each other. Can be reinforced.

FIG. 2A is a front view of the bottle container 10 shown in FIG. 1, and FIG. 2B is a cross-sectional view along the longitudinal direction of FIG. The part is shown enlarged. As shown in FIG. 2, the mountain-shaped portion 21 and the valley-shaped portion 22 are both curved surfaces, and the surface of the side surface portion 16 of the container body 11 has a gentle uneven shape.

Here, when pressure is applied to the upper end surface portion 14 and the lower end surface portion 15, as shown in FIG. 3, the valley-shaped portion 22 is further curved inward and folded between the mountain-shaped portions 21. Thereby, the container main body 11 can be contracted in the longitudinal direction. To return the container body 11 to the state shown in FIG. 2 by stretching, the upper end face 14 and the lower end face 15 may be pulled in directions opposite to each other. 3A is a front view of the bottle container 10 shown in FIG. 1 in a contracted state, and FIG. 3B is a cross-sectional view along the longitudinal direction of FIG. The area enclosed by is enlarged.

As described above, the container main body 11 has a state shown in FIG. 3 in which the trough 22 is completely folded between the peaks 21, and a state shown in FIG. 2 in which the trough 22 is completely developed. Thus, it can be expanded and contracted in two stages, and the volume can be easily increased or decreased or the shape can be easily changed. Further, since the expansion and contraction of the container main body 11 can be performed not only once but also many times, it can be reused for various purposes according to the space and the amount of the contents.

It is preferable that the width of the valley 22 is larger than the width of the mountain 21. Thereby, the container body 11 can be reduced to a smaller size.

As described above, according to the bottle container 10 of the present embodiment, since the bellows structure 20 including the mountain-shaped portion 21 and the valley-shaped portion 22 is provided on the side surface portion 16 of the container main body 11, The container body 11 can be expanded and contracted. Therefore, after the contents of the bottle container 10 are removed, used, or drunk, the container body 11 can be easily contracted, and the capacity can be easily increased or decreased or the shape can be easily changed. Even when the bottle container 10 is purchased and used on the go, the purchaser can take it home without being bulky, and can promote personal reuse and reduce the amount of garbage. Furthermore, if individual reuse is promoted without recycling, the resources required for recycling can also be saved, which can be expected to contribute to more efficient use of resources.

[0018] Even if recycling is performed, the efficiency of collection and transport operations is improved because the volume is extremely small. This will reduce the cost of recycling and make it easier to recycle.

In addition, the bottle container 10 can easily increase or decrease the capacity or change the shape, so that it can be used not only for the sale of liquids such as beverages but also for other uses. For example, it can be used as a transport container for transporting a small amount of liquid from one point to another point.

The chevron 21 and the trough 22 are formed in a spiral with a straight line L connecting the centers of the upper end face 14 and the lower end face 15 as a helix axis. Since the thickness is different from that of the mold portion 22, it is possible to reinforce that the valley mold portion 22 having a small thickness is easily broken by applying a force.

Since the width of the valley 22 is larger than the width of the mountain 21, the container body 11 can be made smaller. In addition, the bellows structure 20 including the mountain-shaped portion 21 and the valley-shaped portion 22 can also have a non-slip effect.

As described above, the present invention has been described with reference to the embodiments. However, the present invention is not limited to the above-described embodiments, and can be variously modified. For example, in the above embodiment, the case where the plane shape of the container body 11 is circular has been described, but the present invention is also applied to the case where the plane shape of the container body 11 is polygonal, for example, rectangular or hexagonal. The same effect can be obtained. However, in the case of a circular shape, physical stress is applied uniformly to the material when the container body 11 expands and contracts.

Further, in the present embodiment, the container body 11 has a state in FIG. 3 in which the trough-shaped portion 22 is completely folded between the mountain-shaped portions 21, and a view in which the trough-shaped portion 22 is completely developed. 3 can be expanded and contracted in two stages. However, the valley-shaped portion 22 is completely folded between the mountain-shaped portions 21 and the valley-shaped portion 22 is completely folded. The container main body 11 may be expanded and contracted stepwise between the state shown in FIG. Thereby, for example, when the content sealed in the bottle container 10 becomes small, it is possible to shrink the container body little by little, and the convenience of the bottle container 10 is further improved.

Further, in the present embodiment, the chevron-shaped portion 21 and the valley-shaped portion 22 of the bellows structure 20 are formed in a spiral shape with a straight line connecting the centers of the upper end surface portion 14 and the lower end surface portion 15 as a spiral axis. However, a simple bellows shape may be used instead of a spiral shape as in the bellows structure 50 shown in FIG.

In the present embodiment, the bellows structure 20 is formed over the entire side portion 16. However, for convenience of attaching a label such as a product name or a component display to the side portion 16, the bellows structure is used. The structure 20 may be formed only on a part of the side surface portion 16.

In the bellows structure 20, it is also possible to exchange the mountain-shaped portion 21 and the valley-shaped portion 22, for example, to make the mountain-shaped portion 21 thinner than the valley-shaped portion 22.

Further, although the capacity of the container body 11 shown in FIG. 1 is 500 ml, the present invention can be applied to a case where the container body 11 has a capacity smaller than 500 ml or larger than 500 ml. is there.

[0028]

[Effect of the invention]

 As described above, the bottle container according to any one of claims 1 to 5 can be expanded and contracted in the longitudinal direction by the expansion and contraction structure formed in the container main body. After removal, use, and drinking, it can be easily contracted, and it is easy to increase or decrease the capacity or change the shape. Therefore, even if the bottle container of the present invention is purchased and used on the go, it can be taken home without bulk by the purchaser, promoting personal reuse and reducing the amount of waste. Furthermore, if personal reuse is promoted without resorting to recycling, the resources required for recycling can also be saved, which can be expected to contribute to more efficient use of resources.

Further, even if the recycling is performed, the effect of improving the efficiency of the collection operation and the transportation operation can be achieved because the volume is extremely small. This reduces the cost of recycling and makes it easier to recycle.

In addition, since it is easy to increase or decrease the volume or change the shape, it is possible to further expand the use of not only a container for selling liquids such as beverages but also its use. For example, it can be used as a transport container for transporting a small amount of liquid from one point to another point.

[0031] In particular, according to the bottle container of the second aspect, since the bellows structure including the mountain-shaped portion and the valley-shaped portion is provided on the side portion, the capacity can be increased and decreased, and the anti-slip effect can be obtained. Can be raised.

[0032] In addition, in particular, according to the bottle container of the third aspect, the mountain-shaped portion and the valley-shaped portion are formed in a helical shape with a straight line connecting the centers of the pair of end surfaces as a helical axis. Therefore, it is possible to reinforce the fact that the thickness is different between the mountain-shaped portion and the valley-shaped portion so that a force is applied to the thin-shaped valley-shaped portion and the valley-shaped portion is easily broken.

According to the bottle container according to the fourth aspect, the mountain-shaped portion has the first width and the valley-shaped portion has the second width larger than the first width. The body can be further reduced.
