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 PET bottle containing a soft drink or the like.

[0002]

2. Description of the Related Art In recent years, PET bottles have become the mainstream of packaging forms for soft drinks that are retailed in stores, instead of conventional bottles and cans. Various storage containers for carrying PET bottles, such as water bottles, used for consuming beverages in PET bottles outdoors have already been commercialized. These storage containers are highly fashionable, and also have effects such as preventing the temperature of the beverage from rising and preventing the dew condensation on the surface of the PET bottle from adhering to the clothes.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention After a plastic bottle is put in a storage container, beverages are sequentially consumed, and the finally empty plastic bottle can be discarded in a trash box or a resource recovery box. However, since the PET bottle storage container is used continuously, it is necessary to always carry the storage container while going out, even after discarding the PET bottle. The storage container inevitably has a larger volume than a PET bottle, and it is inconvenient to carry it by itself. Therefore, when the storage container is not used, it is desirable to reduce the volume as much as possible and store it in a bag or a rucksack if possible.

Further, when the cap of the PET bottle in the storage container is rotated to drink the beverage, the cap cannot be opened if the entire PET bottle rotates.
In order to solve this problem, if you take measures to prevent rotation of the PET bottle in the storage container, the structure will be complicated and it will be difficult to provide the product at low cost, and only compatible with specific PET bottles, etc. I have a problem.

The upper lid of the storage container must be attached and detached each time a drink is drunk. Therefore, it is desirable that the attachment / detachment can be performed as easily as possible. If the top lid is fixed to the case body by a screw mechanism, it usually takes time to rotate the top lid once more than once, and if the top lid is not closed properly, it may vibrate and come off the case body. There is also.

The present invention has been made in view of these circumstances, and in addition to having a proper cooling function without allowing clothes to get wet due to dew condensation, it can store various types of PET bottles and is not used. The object of the present invention is to provide a plastic bottle storage container that has a function of reducing the volume, is excellent in portability and storage, and can be easily attached and detached with the upper lid.

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a cylindrical case body for covering a side peripheral surface of a plastic bottle in a state where a cap projects. An upper lid and a lower lid that can be opened and closed to close the upper and lower openings of the case body, and the case body is made up of a plurality of tubular bodies , and the inner periphery of each tubular body above the inner surface is
Each has a stopper that protrudes toward
The entire circumference below the outer peripheral surface of each cylindrical body that is adjacent to the upper side
Forms a slide part that protrudes outward and
The id part uses the inner peripheral surface of the adjacent tubular body as a guide.
The outer diameter of the slide part is adjacent downward so that
The inner diameter of the cylindrical body
The two tubular bodies are the sliding part of one tubular body and the other tubular body.
It is inseparable by contact with the stopper
When the PET bottle is not stored inside, the user can apply external force to the case body to deform the case body and reduce the volume. When it is used again, it is possible to return it to the original state by applying an external force opposite to that when the volume is reduced.

Next, the shape of the tubular body and the relationship between the tubular bodies will be described using two adjacent tubular bodies (cylindrical body A and tubular body B). The cross-sectional shape of the inner peripheral surface of the cylindrical body A is the same in the height direction, but a stopper projecting inward is provided over the entire circumference at the upper part. The tubular body B has a size that can be stored in the inner peripheral portion of the tubular body A, and the cross-sectional shape of the outer peripheral surface thereof is the same in the height direction and smaller than the inner diameter of the stopper of the tubular body A. Further, at the lower part of the outer peripheral surface of the tubular body B, a slide portion is provided which is projected to the outer side over the entire circumference. The sliding portion of the tubular body B is slightly smaller than the inner peripheral surface of the tubular body A. As a result, the tubular body B can smoothly move using the inner peripheral surface of the tubular body A as a guide. When the tubular body B is moved upward, the stopper of the tubular body A interferes with the sliding portion of the tubular body B, so that the tubular bodies are not separated. By giving the relationship between the tubular body A and the tubular body B mentioned above to all the tubular bodies, all the tubular bodies forming the case body are stored inside the largest tubular body. can do. The largest cylindrical body is located at the bottom of the case body, and is a pressure contact body that fixes the lower lid and PET bottle.
A stop ring that stops the tubular body is attached.
The smallest tubular body is located at the top 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.

According to the second aspect of the present invention, the plastic bottle storage container can store various types of plastic bottles, and when the cap is turned, the plastic bottle does not rotate in the storage container at the same time. Rotation preventing means for the PET bottle is provided around the upper opening. As the 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 pressure contact body made of an elastic and non-slip material is arranged inside the bent wall. May be. In addition, if the protruding wall is also formed into a cylindrical shape in the opening of the lower lid and a pressure contact body is also placed inside this,
Furthermore, the rotation prevention function can be effectively exhibited. The pressure contact member may be fixed with an adhesive so as not to separate from the PET bottle storage container. When the lower lid is opened and the PET bottle is loaded into the storage container, and then the lower lid is closed, the PET bottle is sandwiched between the upper and lower pressure contact bodies, and movement and rotation in the storage container are restricted. Therefore, when the cap is removed, the PET bottle does not rotate at the same time. Further, in this case, since the pressure contact body has elasticity, it is possible to absorb the difference in shape of the PET bottle. When the case body is composed of multiple tubular bodies, it can freely rotate between adjacent tubular bodies.Therefore, when the cap is rotated, the tubular body, the pressure contact body, and the PET bottle also rotate together. May not be able to open the cap.
Therefore, it is necessary to take measures to prevent the adjacent tubular bodies from rotating freely.

According to the third 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 easily attaching and detaching the upper lid as frequently as possible when the plastic bottle is stored. A plurality of grooves are formed, and a convex portion that fits into the grooves is formed on the upper lid. This convex portion 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 portion of the upper lid with the groove of the case body, and then place the upper lid on the case body. When brought close to each other, 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 circumference of the case body, it can be elastically deformed, so that the upper lid can move while contacting the case body. When the convex portion moves to the position where the groove is present, it elastically enters the groove, and then the upper lid 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, so that the upper lid is released from the case body. In this method, when removing the upper lid, it is only necessary to rotate the convex portion at a slight angle so as to separate from the groove.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION 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 side of the cylindrical body 21 located at the bottom is open, and a stopper 24 protruding inward is formed over the entire inner peripheral surface above the inner peripheral surface. A slide portion 25, which protrudes outward, is formed over the entire circumference below the outer peripheral surface of the tubular body 22, which is adjacent to the upper side of the tubular body 21. Slide part 25
The outer diameter of is slightly smaller than the inner diameter of the tubular body 21. Therefore, the slide portion 25 can smoothly move 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 tubular body 21 come into contact with each other, the respective tubular bodies are not separated. Here, on the contact surface between the stopper 24 and the slide portion 25, a groove and a projection (not shown) are formed in order to prevent them from freely rotating between the two cylindrical bodies. The above structure can be provided between the cylindrical body 22 and the cylindrical body 23 to make the case body 1 extendable and contractible. Since the stopper ring 18 is fitted in the opening 4b at the bottom of the case body 1, the cylindrical bodies 22, 2
3 is also restricted in the downward movement range. FIG. 1 shows a state in which a plastic bottle is stored, and a force that extends in the vertical direction acts on the case body 1 via the pressure contact bodies 6a and 6b. Therefore, the tubular bodies 21, 22, and 23 are in the state of being pulled out to the maximum. FIG. 2 shows a state in which the PET bottle is not stored, and the cylindrical bodies 22 and 23 and the upper lid 2 are shown.
Are housed inside the tubular body 21. In this embodiment, the number of tubular bodies is three, but the number of tubular 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 joined to the tubular body 21 via a hinge 11. In order to fix the lower lid 3 to the facing portion of the hinge 11, a boss 13 is formed on the tubular body 21 side and a locking piece 12 is formed on the lower lid 3 side. The locking piece 12 has a hole for fitting with the boss 13, and the outer edge portion of this hole has a plurality of notches in the radial direction. When the lower lid 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 when the end of the boss 13 having the largest diameter is passed, the lower lid 3 is pressed. 3 is closed. When the PET bottle 7 is taken in and out, the end portion of the locking piece 12 can be pulled and released from the boss 13 to open the lower lid 3. A projecting wall 19 is provided on the inner surface of the lower lid 3, and a sponge pressure contact member 6b is joined to the inside thereof.

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

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, there are formed a sloping portion 17 having a smaller cross section toward the top, and six grooves 14 on the same cross section. Each groove 14
At both end portions of the above, an inclined portion 16 that smoothly connects the bottom portion of the groove 14 and the side surface of the case body 1 is provided. Further, as shown in FIG. 5, a convex portion 15 that fits into the groove 14 is formed on the lower surface of the upper lid 2. When closing the upper lid 2, the procedure is as follows. First, when the upper lid 2 is moved so that the convex portion 15 is located right above the groove 14 and then the upper lid 2 is brought close to the case body 1, 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, since the side peripheral surface of the upper lid 2 expands due to elastic deformation, the convex portion 15 can move while contacting the case body 1. Then, when the convex portion 15 moves to the groove 14, the convex portion 15 elastically moves into the groove 14. 6A and 6B show the upper lid 2.
Indicates a closed state. After this, the upper lid 2 will not come off even if pulled upward. When closing the upper lid 2, the upper lid 2 is pressed against the case body and then rotated to remove the groove 1
4 and the convex portion 15 may be fitted together. When removing the upper lid 2, it is only necessary to grasp the outer peripheral surface of the case body 1 with a hand and rotate it slightly. When the upper lid 2 is rotated, FIG.
As shown in (d), the convex portion 15 is spread in the radial direction by the action of the inclined portion 16 provided at the end of the groove 14, and is further floated upward by the inclined portion 17. At this stage, the convex portion 15 is separated from the groove 14, so that the upper lid 2 is attached to the case body 1.
Is released from.
