Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a foldable cup structure that is convenient for carrying, and more specifically, it is composed of a foldable cup body and a lid that can be detachably attached to it. Regarding the cup structure to be done.

[Conventional technology]

Conventionally, paper cups and plastic cups have been used as portable cups for hiking and traveling. However, it is hard to say that these cups are hygienic because their mouths are touched by their hands and fingers during transportation and handling, and dust and the like adhere inside. Therefore, a cup with a lid is recommended as a hygienic and safe cup.

[Issues to be solved by the device]

However, the conventional cups with lids are bulky because they cannot be stacked when carrying a plurality of them. Further, the attachment / detachment of the cup body and the lid is often done by screwing or fitting, and as the material of the cup body and the lid, a relatively thick hard plastic or metal is used, and there is a problem that the weight becomes large.

In view of the drawbacks of such a conventional cup with a lid, the present invention aims to provide a novel cup structure which is not bulky during transportation and can be reduced in weight.

[Means for Solving the Problems]

The cup structure of the present invention for achieving the above object has a bottom and a foldable peripheral wall portion, and a cup body having an open upper portion, and the opening portion is covered with the peripheral wall portion of the cup body folded. And a lid configured to sandwich the upper edge portion and the bottom portion of the peripheral wall portion, wherein at least the peripheral wall portion 3 of the cup body 1 is made of an elastic thin-walled integrally formed body, and its extension In this state, the outer circumference of the cross section is formed into a waveform with a small amplitude, and an annular fold 6 is formed on the peripheral wall portion 3 at the inflection portion of each wave, and in the contracted state, the folds 6 with adjacent amplitudes
The distance is approximately equal to 6 distances, and the entire peripheral wall portion 3 is bent in a zigzag shape so as to elastically elongate in the extending direction. It has a hooking portion 10 that is bent toward the center side, the cup body 1 is in a contracted state, and the lid plate 8 of the lid 7 is
It is configured so as to be elastically sandwiched between the and the hooking portion 10.

[Action]

In the cup structure of the present invention, since the peripheral wall portion of the cup body is foldable, when used, the peripheral wall portion is extended to form a liquid storage portion so as to function as a cup.
When the mobile phone is carried, the peripheral wall is folded and compressed into a flat shape, the opening is covered with the lid, and the upper edge and the bottom of the peripheral wall are sandwiched, so that the lid can be attached to the cup body with one touch. After mounting in this manner, the lid is secured to the cup body by a repulsive force due to the folding of the peripheral wall portion. Further, in order to remove the lid from the cup body, the lid may be pressed against the cup body with a slight force to release the clamping of the bottom portion.

In such a method of attaching and detaching the cup body and the lid, since a large coupling force is not required, the material of the cup body and the lid can be selected to be thinner and lighter than the conventional materials.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an example of a cup structure of the present invention, which is a partial cross-sectional view showing a state in which a lid is attached to the cup body, and FIG. 2 shows a state in which the lid is removed from FIG. 1 and the cup body is extended. It is a fragmentary sectional view shown.

1 and 2, the cup body 1 has a bottom portion 2 and a peripheral wall portion 3 which can be folded in a bellows shape, and an inside of an upper edge portion 4 of the peripheral wall portion 3 is opened. Further, the peripheral edge portion 5 of the bottom portion 2 projects downward in a ring shape. The peripheral wall portion 3 is provided with folds 6 at appropriate intervals along the circumferential direction, and the folds 6 can be folded or extended as shown in FIG. 1 or FIG.

On the other hand, the lid 7 includes a lid plate 8 having a diameter slightly larger than the outer diameter of the cup body 1, a side wall portion 9 bent downward from a peripheral edge portion of the lid plate 8, and a lower edge portion of the side wall portion 9. It is composed of a hanging portion 10 that is bent inward. Side wall 9
May have a ring shape that covers the entire peripheral edge of the lid plate 8, but may have a configuration in which a plurality of bent pieces are provided at appropriate intervals on the peripheral edge portion. Similarly, the hooking portion 10 can also be configured by a ring shape or a plurality of bent pieces.

The material of the cup body 1 and the lid 7 is not particularly limited as long as it has a predetermined rigidity, and paper, a relatively thin plastic such as polyethylene, polystyrene, or polyvinyl chloride, and a metal thin plate can be used. However, it is preferable that the lid material has some elasticity in addition to rigidity.

Next, in order to scoop from the state of FIG. 2 to the state of FIG. 1, first, the peripheral wall portion 3 of the cup body 1 shown in FIG. 1 is folded, and then the upper opening portion is covered with the lid plate 8 of the lid 7. With
The side wall 9 is located outside the peripheral wall portion 3 of the cup body,
Next, the lid plate 8 and the bottom portion 2 of the cup body are sandwiched by hand, and the side wall 9 is pressed inward while compressing the peripheral wall portion 3 to slide the hooking portion 10 to the inside of the peripheral edge portion 5 of the bottom portion 2 and fit it. . This state is shown in FIG. 2, and the peripheral wall portion 3 of the cup body 1 is shown.
The upper edge portion 4 and the bottom portion 2 are sandwiched by the lower surface of the lid plate 8 of the lid 7 and the hook portion 10.

In the state shown in FIG. 2, a reliable connection is maintained by the repulsive force generated by the folding of the folded peripheral wall portion 3 and the protruding portion of the peripheral edge portion 5 provided on the bottom portion 2. However, the peripheral portion 5 may be omitted in some cases.

To return from the state of FIG. 1 to the state of FIG. 2, the lid plate 8 and the bottom portion 2 are sandwiched and pressed by the hand, and the catch portion 10 is pulled outward with a finger to remove the lid 7 from the cup body 1. Then, by supporting the outer peripheral portion of the bottom portion 2 by hand and pulling up the peripheral wall portion 3 upward, the state shown in FIG.

It is preferable that the cup body according to the present invention is self-supporting when it is used as shown in FIG. This self-supporting property is the recoverability of the fold line 6 of the peripheral wall portion 3, that is, when the hand is released from the folded state, the fold line 6 is repulsive force.
It depends on the extent to which the peripheral wall portions before and after are restored to a state in which they are almost parallel to each other. This self-supporting property can be easily ensured in the case of hard paper or plastic. However, independence is not an essential requirement in the present invention, and even if it is insufficient, it can be sufficiently used as a cup by manually grasping the peripheral wall portion from the outside.

[Effect of device]

Since the cup structure of the present invention is configured as described above, it has the following effects.

At least the peripheral wall portion 3 is made of an elastic thin-walled integrally molded body, and it elastically contracts in a zigzag shape to form a lid 7
Since it is configured to be elastically sandwiched between the cover plate 8 and the hanging portion 10, the structure is extremely simple, the expansion and contraction operation is simple, and the usability is extremely good. At the same time, it is easy to manufacture and can be provided at low cost. Further, it is possible to maintain the folded state in a stable manner while being lightweight and compact.
