Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing a plastic bottle containing a soft drink or the like.

[0002]

2. Description of the Related Art In recent years, plastic bottles, which are retailed at stores, are mainly packaged in plastic bottles instead of bottles and cans. Various storage containers for carrying plastic bottles used when drinking beverages in plastic bottles outdoors, such as water bottles, have already been commercialized. These storage containers are excellent in fashionability, and also have effects such as preventing a rise in the temperature of the beverage and preventing condensation generated on the surface of the PET bottle from adhering to clothes.

[0003]

After the PET bottles are placed in the storage container, the beverages are sequentially consumed, and the finally empty PET bottles can be dumped in a trash box or a resource collection box. However, the plastic bottle storage container is used continuously, and it is necessary to always carry the storage container while going out, even after discarding the plastic bottle. The storage container is inevitably larger in volume than the PET bottle, and it is inconvenient to carry it alone. Therefore, when the storage container is not used, it is desirable to reduce the volume as much as possible, and if possible, store it in a bag or rucksack.

In addition, when drinking a beverage, when the cap of the PET bottle in the storage container is rotated, the cap cannot be opened if the entire PET bottle is rotated.
If measures to prevent the rotation of the PET bottles are taken in the storage container to solve this problem, the structure becomes complicated and it becomes difficult to provide the product at low cost, and only the specific PET bottles are supported. There is a problem.

[0005] It is necessary to attach and detach the upper lid of the storage container every time a drink is taken. Therefore, it is desirable that attachment and detachment can be performed as easily as possible. If the upper lid is fixed to the case body with a screw mechanism, it takes time to turn the upper lid one or more turns when attaching and detaching, and if it is not properly closed, it may come off the case body due to vibration. There is also.

[0006] The present invention has been made in view of such circumstances, and in addition to having an appropriate cooling function without wetting clothes and the like due to dew condensation, can store various types of PET bottles and can be used when not in use. An object of the present invention is to provide a PET bottle storage container which has a function of reducing the volume, is excellent in portability and storage, and can easily attach and detach the upper lid.

[0007]

Means for Solving the Problems In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a cylindrical member that covers the periphery of a plastic bottle among members constituting the plastic bottle storage container. The case body has a function of being deformed by an external force. When the PET bottle is not stored inside, the case body is deformed when the user applies an external force to the case body, so that the volume can be reduced. When used again, it is also possible to return to the original state by applying the opposite external force when the volume is reduced.

The means for deforming the case body is not particularly limited. For example, the case body is made of a bellows structure which can expand and contract in the vertical direction, or the case body is made of an elastic material, and the side of the case body is formed. Means such as crushing, changing the shape from a cylindrical shape to a plate shape, and fixing with a clip may be used, but as in the invention according to claim 2, the case body is composed of a plurality of cylindrical bodies, and the inner diameter of the cylindrical body If the external dimensions are different from each other, the material to be used can be freely selected and a product excellent in strength and durability is desirable. The shape of the cylindrical body and the relationship between the cylindrical bodies will be described using two cylindrical bodies (cylindrical body A and cylindrical body B) as follows. The cross-sectional shape of the inner peripheral surface of the cylindrical body A is the same in the height direction, but a stopper is provided on the upper portion and protrudes inward over the entire circumference. The cylindrical body B has a size that can be stored in the inner peripheral portion of the cylindrical body A, and the outer peripheral surface has the same sectional shape in the height direction and is smaller than the inner diameter of the stopper of the cylindrical body A.
Further, a slide portion protruding outward is provided over the entire circumference at the lower portion of the outer peripheral surface of the cylindrical body B. The slide portion of the tubular body B has a size slightly smaller than the inner peripheral surface of the tubular body A. Thus, the cylindrical body B can move smoothly using the inner peripheral surface of the cylindrical body A as a guide. When the cylindrical body B is moved upward, the stopper of the cylindrical body A and the sliding portion of the cylindrical body B interfere with each other, so that the cylindrical bodies are not separated.
By giving the relationship between the cylindrical body A and the cylindrical body B mentioned above to adjacent cylindrical bodies, all the cylindrical bodies constituting the case body are housed inside the largest cylindrical body. can do. The shape of each cylindrical body may be a conical shape other than the cylindrical shape as long as it can expand and contract. The largest cylindrical body is located at the bottom of the case body, and is equipped with a lower lid, a pressure contact body for fixing the plastic bottle, and a stop ring for stopping the cylindrical body. The smallest cylindrical body is located at the uppermost part of the case body, and has an upper lid, a hanging string, and a pressure contact body attached thereto. With the above structure, the case body can be freely expanded and contracted, and the case body can have the maximum size when the PET bottle is stored, and can have the minimum size when there is no PET bottle.

The object of the present invention is to provide a plastic bottle storage container capable of storing various types of plastic bottles, and to prevent the plastic bottle from rotating simultaneously in the storage container when turning the cap. A means for preventing rotation of the plastic bottle is provided around the upper opening. As a rotation preventing means, for example, a bent wall having an inverted U-shaped cross section is formed around the opening at the upper end of the case body, and a press-contact body using an elastic non-slip material is disposed inside the bent wall. You may. Also, if the protruding wall is formed into a cylindrical shape also at the opening of the lower lid, and if a press-contact body is arranged inside this,
Furthermore, a rotation prevention function can be effectively exhibited. The press contact body may be fixed with an adhesive so as not to be detached from the PET bottle storage container. After the lower lid is opened and the PET bottle is loaded into the storage container, when the lower lid is closed, the PET bottle is sandwiched between the upper and lower pressure contact bodies, and the movement and rotation in the storage container are restricted. Therefore, when removing the cap, the plastic bottle does not rotate at the same time. Further, in this case, since the pressure contact body has elasticity, the difference in the shape of the plastic bottle can be absorbed. In the case where the case body is composed of a plurality of cylindrical bodies as in the second aspect of the present invention, the cylindrical body can be freely rotated between adjacent cylindrical bodies. And the PET bottle may also rotate with it, preventing the cap from opening. Therefore, it is necessary to take measures to prevent the adjacent cylindrical body from rotating freely.

According to a fourth aspect of the present invention, the upper lid is attached to the outer peripheral surface of the upper part of the case body for the purpose of making it possible to easily attach and detach the upper lid as frequently as possible when storing the plastic bottle. In addition to forming a plurality of grooves, the upper lid is formed with a convex portion that fits into the grooves. This convex part can be elastically deformed in the radial direction of the upper lid.When attaching the upper lid to the case body, first align the convex part of the upper lid with the groove of the case body, and then put the upper lid on the case body. When approached, the convex portion starts to contact the outer peripheral surface of the case body. Although the inner diameter of the convex portion is smaller than the outer periphery of the case body, it can be elastically deformed, so that the upper lid can move while contacting the case body. When the protruding portion moves to a position where the groove is present, the protrusion enters the groove by elasticity, and the upper cover does not come off even if pulled upward. When the upper lid connected to the case body is rotated, the convex portion rides on the outer peripheral surface of the case body through the inclined portion provided at the end of the groove. At this stage, the convex portion is separated from the groove, and the upper lid is released from the case body. In this method, when removing the upper lid, it is only necessary to rotate a slight angle at which the convex portion is detached from the groove.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. The case body 1 has a sufficient size for the PET bottle 7 to be stored, and is composed of a plurality of cylindrical tubular bodies 21, 22, 23. The lower end of the cylindrical body 21 located at the bottom is open, and a stopper 24 projecting inward is formed over the entire inner peripheral surface. A slide portion 25 protruding outward is formed over the entire circumference below the outer peripheral surface of the cylindrical body 22 adjacent to the upper side of the cylindrical body 21. Slide part 25
Has an outer diameter slightly smaller than the inner diameter of the tubular body 21. Therefore, the slide portion 25 can move smoothly using the inner peripheral surface of the tubular body 21 as a guide, but as the tubular body 22 is moved upward, the slide portion 2 of the tubular body 22 is moved.
5 and the stopper 24 of the cylindrical body 21 are in contact with each other, so that the respective cylindrical bodies are not separated. Here, grooves and projections (not shown) are formed on the contact surface between the stopper 24 and the slide portion 25 in order to prevent free rotation between the two cylindrical bodies. The above structure can be provided between the tubular body 22 and the tubular body 23 to make the case body 1 expandable and contractable. Since the stopper ring 18 is fitted into the opening 4b at the lower part of the case body 1, the cylindrical bodies 22, 2 are fitted.
In No. 3, the downward movement range is also restricted. FIG. 1 shows a state in which a plastic bottle is stored, and a force to extend the case body 1 in the vertical direction acts on the case body 1 via the press contact bodies 6a and 6b. Therefore, each of the tubular bodies 21, 22, 23 is in a state of being pulled out to the maximum. FIG. 2 shows a state where the PET bottle is not stored, and the cylindrical bodies 22 and 23 and the upper lid 2 are not stored.
Is housed inside the tubular body 21. In the present embodiment, the number of the cylindrical bodies is three, but the number of the cylindrical bodies can be changed each time according to the size of the plastic bottle, the length of expansion and contraction of the case body, and the like.

The lower lid 3 is connected to the cylindrical body 21 via the hinge 11. A boss 13 is formed on the cylindrical body 21 side and a locking piece 12 is formed on the lower lid 3 side in order to fix the lower lid 3 to the opposing portion of the hinge 11. The locking piece 12 has a hole for fitting into the boss 13, and the outer edge of the hole has a plurality of cuts in the radial direction. When the lower cover 3 is joined to the case body 1 and the hole of the locking piece 12 is pressed against the boss 13, the periphery of the hole is deformed due to the notch, and the lower cover 3 passes through the end of the boss 13 where the diameter is the largest. 3 is closed. When the PET bottle 7 is taken in and out, the end of the locking piece 12 is pulled to be released from the boss 13 and the lower lid 3 can be opened. A projecting wall 19 is provided on the inner surface of the lower cover 3, and a sponge pressing member 6 b is joined to the inside of the projecting wall 19.

The cylindrical body 23 constituting the uppermost part of the case body 1
Has an opening 4a from which only the upper part of the plastic bottle 7 and the cap 8 protrude, and a bent wall 5 having an inverted U-shaped cross section is formed on the outer periphery of this opening. A ring-shaped press contact body 6a made of sponge is fitted into the inner surface of the bent wall 5. Two rings 9 are rotatably mounted on the outer peripheral surface of the tubular body 23, and a hanging string 10 is passed through the rings 9. FIG. 3 shows a procedure for loading the PET bottle into the storage container. The loading operation is completed by moving each part in the direction shown by the arrow.

The attachment and detachment of the case body 1 and the upper lid 2 are realized by the following method. As shown in FIG. 4, on the outer peripheral surface of the upper part of the case body 1, a slope portion 17 having a cross section that becomes smaller upward, and six grooves 14 are formed on the same cross section. Each groove 14
At both end portions, an inclined portion 16 is provided to smoothly connect the bottom of the groove 14 and the side surface of the case body 1. On the lower surface of the upper lid 2, a convex portion 15 that fits into the groove 14 is formed as shown in FIG. The closing of the upper lid 2 is performed in the following manner. First, the upper cover 2 is moved so that the convex portion 15 is located directly above the groove 14, and then the upper cover 2 is brought close to the case body 1, and the convex portion 15 starts to contact the outer peripheral surface of the case body 1. Convex part 1
Although the inner diameter of 5 is slightly smaller than the outer circumference of the case body, the side peripheral surface of the upper lid 2 expands by elastic deformation, so that the convex portion 15 can move while contacting the case body 1. When the convex portion 15 moves to the groove 14, the convex portion 15 enters the groove 14 by elasticity. FIGS. 6A and 6B show the upper lid 2
Indicates a closed state. After this, the upper lid 2 does not come off even if it is pulled upward. When closing the upper cover 2, the upper cover 2 is rotated after being pressed against the case body.
4 and the convex portion 15 may be fitted together. When removing the upper lid 2, it is only necessary to hold the outer peripheral surface of the case body 1 by hand and slightly rotate it. When the upper lid 2 is rotated, FIG.
As shown in (d), by the action of the inclined portion 16 provided at the end of the groove 14, the convex portion 15 is pushed out in the radial direction and further rises upward by the inclined portion 17. At this stage, since the convex portion 15 is separated from the groove 14, the upper lid 2 is
Be released from.
