Abstract

Provided is a portable container capable of ensuring the convenience of carrying and ensuring the strength at the time of liquid storage and gripping in an elongated form as a cup while allowing the peripheral wall to be folded. A straight ring body 3 having a straight short cylindrical shape and an inclined ring body 4 having an inverted truncated truncated conical shape are alternately and sequentially connected via a thin portion 5 to form a peripheral wall 2, and a lowermost end. In this configuration, the bottom plate 6 is connected to the straight ring body 3, and the peripheral wall 2 is folded by reversing the inclined ring body 4 at the thin portion 5 by applying a force to the peripheral wall 2 from above and below.

Description

  The present invention mainly relates to a portable container for outdoor use.

  It is normal to bring a cup for drinking outdoors. In that case, it is lightweight, easy to use, and can be disposable, so many paper cups are stacked and stored in a bag. Things have been done. However, even if it does so, it must be bulky, and the dissatisfaction that it crushes at the time of bringing it remains.

  For this reason, the following proposals have been made as containers that are not bulky and easy to carry.

Japanese Utility Model Publication No. 7-19327 Utility Model Registration No. 3054459

  The device "Cup structure" of Patent Document 1 is a thin-walled integrally molded body whose peripheral wall portion has elasticity, and is a structure in which the wall is elastically contracted and folded into a zigzag shape. Since the inverted truncated cone and the truncated cone are simply continuous, they are extremely weak against pressure from above and below in the extended form as a cup, and will deform even if they are held in a state of containing liquid. Not only is it easy to drink, it is not easy to drink, but it can be dangerous if you store something like hot water.

In addition, the device “portable cup” of Patent Document 2 is provided with a plurality of belt-shaped portions and a plurality of folding portions alternately so as to be expandable and contractible, and each belt-shaped portion is slightly larger than the outer diameter of the belt-shaped portion immediately below it. Although it is a formed configuration, the folding part is thinner than the band-like part so as to be reversed when folded, so that the pressure is applied from above and below and from the side in an elongated form as a cup, similar to the idea of Patent Document 1 above. There are drawbacks such as extremely weak, easy to deform and difficult to drink.

  Therefore, the present invention is a portable container that has been developed to eliminate the disadvantages, inconveniences, and dissatisfactions of the prior art described above, and ensures the convenience of carrying and allows the peripheral wall to be folded while being expanded as a cup. An object of the present invention is to ensure the strength at the time of liquid storage and gripping.

In order to solve the above problems, a portable container according to the present invention includes a linear ring body having a straight short cylindrical shape and an inclined ring body having an inverted frustoconical short cylinder shape that are alternately and sequentially connected via a thin portion. And the bottom plate is connected to the straight ring body at the lowermost end.

In the present invention described above, the peripheral wall is formed of a straight ring body and an inclined ring body having an inverted truncated conical short cylinder shape, both of which are continuous through a thin portion, and the presence of the straight ring body causes the vertical direction and Excellent pressure resistance against lateral load, and hardly bulges outward when liquid is stored, so it can not only stably maintain its shape but also dents inward when gripped. Since deformation hardly occurs, not only is it easy to handle, but also safety can be ensured.

In addition, when a force is applied from above and below in the extended posture of the peripheral wall, the inverted truncated cone-shaped inclined ring body is inverted at the thin portion, and the lower linear ring body is fitted inside the inverted inclined ring body. Since the peripheral wall can be easily folded and is not bulky as a whole, the present invention has many excellent effects such as being very convenient for carrying.

It is sectional drawing which shows an example of a portable container. It is also a front view. It is a bottom view similarly. It is sectional drawing which shows the state which folded the surrounding wall and covered the cover body.

The portable container 1 of the present invention is formed by arranging a peripheral wall 2 in a straight short cylindrical shape with a straight ring body 3 and an inverted frustoconical short cylindrical shape with an inclined ring body 4 alternately and sequentially through a thin portion 5. The bottom plate 6 is connected to the straight ring body 3 at the lowermost end to constitute a cup container.

In the portable container 1 integrally molded with an elastic resin such as silicon resin or elastomer resin, the linear ring body 3 positioned at the uppermost position of the peripheral wall 2 is relatively thick and Not only can the portable container 1 in an expanded state be easily gripped by placing a finger on the stepped portion, but it has sufficient pressure resistance against external force from the side when gripped, Therefore, there is an advantage that it is easy to drink because it does not deform when the stored liquid is drunk with a mouth.

  Moreover, the tongue piece 7 which protrudes to a side is provided in a part of the baseplate 6, and it is set as the expansion | extension attitude | position of the surrounding wall 2 by drawing this tongue piece 7 below in the state in which the surrounding wall 2 was folded. Can do.

  Since the height of the peripheral wall 2 is the height of the straight ring body 3 or the inclined ring body 4, the compact handling can be performed.

  Then, in the state in which the peripheral wall 2 is folded in FIG. 4, the uppermost linear ring body 3 is covered with the lid body 8 to ensure hygiene when not in use or to store the liquid in the extended state of the peripheral wall 2. It is possible to ensure hygiene at the time and its heat insulation and cold insulation.
