Abstract

PROBLEM TO BE SOLVED: To solve the problem that no paper cup is prepared in any bathrooms found outside home even though we need a cup for toothbrushing after eating, gargling or taking a drug and people carry a toothbrush but not a cub because it is bulky.SOLUTION: A polyethylene film was applied so as to satisfy criteria required for a portable cup, such as a pocket-size, a light weight and a flat shape as much as possible, which however caused lots of problems. Too soft film caused the cup to fall down when pouring water. To solve this problem, the film corresponding to cup's bottom and upper part that the mouth touches is doubled, heated and welded so that the bottom becomes steady.SELECTED DRAWING: Figure 5

Description

Silicone rubber folding mobile cups that are currently on the market are not good in appearance because of the primary color due to the material, and they are bulky and thick, so they do not feel good when used.
In addition, when metal is put in the pocket, it feels strange and the mouth feels cold.
Paper is square or polygonal and difficult to drink, and it is disposable once cut.

Unlike the materials described above, the present invention uses a polyethylene film.
This material is non-toxic, transparent, hygienic, stretchy and ideal as a cup.

The present invention is not a molded product, but an extremely thin material called film. If you put water in a bag of strawberry film, it will fall down to the left and right, and the water will flow immediately, making it impossible to use as a cup.

In the present invention, the bottom is doubled so that even if water is poured into such a soft material, the bottom is doubled, and the film is also stacked on the side wall to make use of the function as a cup. Did.

In order to solve this problem, the present invention fixes the extremely thin ribbon of chemical fiber with resin and winds it with film to fix it firmly. did.
Part of the ribbon was taken out and used as a handle.

How to make a soft material called polyethylene film to function as a cup, the present invention for that purpose, the bottom doubles the film and the side wall part triples even if water is put in, it rises firmly and the opening Is extremely thin and firm and has a pleasant taste.

Top view of tubular film A three-dimensional view of the bottom film that extends left and right and covers a wooden pattern Figure of a round film bent to the left and right folded at 45 degrees Three-dimensional view of the ribbon temporarily secured with the opening facing up Three-dimensional view of film wrapped around the ribbon at the opening

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In FIG. 1, a cylindrical film is laid flat and heated and welded linearly from the end of the film to a radius size.

In Fig. 2, the film is inserted on the cylindrical wooden mold and the cut part is expanded to the left and right, and only the circular part is heated and bonded. This part becomes the bottom.

[FIG. 3] is a method of bending and heating and welding the left and right films that are sandwiched from a round shape at 45 degrees.

[FIG. 4] removes the film from the wooden mold, with the opening up, and temporarily secures the ribbon slightly below.
In FIG. 5, the film on the opening is straddled across the ribbon and lowered to be heated and welded.

1 is a polyethylene film, 2 is heated in a linear shape, 3 is a part of the film, and FIG. 4 is a cylindrical wooden mold 5 is a film that heats and adheres the film only to the round shape, and 6 is out of the round shape The film 7 is a ribbon of chemical fibers 8 is a film with the ribbon wound down.

Claims (2)

The bottom part of the cup is heated and welded linearly from the end of the film to the end of the film, and both ends of the short part are cut. Heat and weld only the part.
And the part which protruded right and left from the round part is folded at 45 degree | times along a cylindrical shape, and the part is heated and welded. At the opening that hits the mouth, a ribbon of chemical fiber that has been hardened with synthetic resin slightly below the upper film is temporarily fixed with a pin, and the upper film is wound down in the form of wrapping the ribbon, and only that portion is heated and welded. Open a part of the ribbon in a fan shape and use it as a handle.
