Description

[Detailed Description of the Invention] The present invention relates to an improved wax-treated paper container, and more specifically, the present invention relates to an improved wax-processed paper container.
wax layer 14 from the inside and the top surface of the bottom part 17.
This is a laminated structure paper chip characterized by a structure in which a paper layer 12, a synthetic resin layer 13, and a paper layer 11 having higher whiteness and better printability than the paper layer are laminated in sequence.

Conventionally, paper cups have poor water resistance, so beverage paper cups are either coated with wax on their inner surfaces, or
Alternatively, paper laminated with a thin film of thermoplastic resin such as polyethylene has been used.

By the way, if the paper is waxed sufficiently to make it highly water resistant, there is a drawback that the appearance of the product deteriorates due to penetration of the wax, and if a film such as polyethylene is laminated on the inside surface, the paper may be difficult to cut. The lack of water resistance on the faces, ie the joint end faces of the cup shells, created a problem.

Therefore, the present invention is to provide a wax-treated paper tip that eliminates these conventional drawbacks.

As shown in FIG. 1, the surface layer 11 is a thin paper layer with relatively high whiteness and good printability, and the back layer 1
In addition to making the paper layer 2 relatively inexpensive and rigid, both paper layers of the surface layer 11 and the back layer 12 are made of polyethylene or a saponified product of polyethylene and ethylene vinyl acetate copolymer, etc. A paper cot is made using laminated paper 10 bonded together with a synthetic resin layer 13 that prevents the permeation of not only moisture but also gas.

Thereafter, a wax layer 14 is applied to the inner surface of the paper tip, as shown in FIG.

In this way, by making the surface layer 1 a paper layer with high whiteness and good printability, the commercial value is increased and the paper layer 1
By making 1 thinner, there is an advantage that the cost can be reduced.

On the other hand, by making the back layer 12 corresponding to the inner surface of the paper tip 15 a relatively inexpensive and thick stiff paper layer, the rigidity of the paper tip can be increased and the cost can be reduced.

And because the inside surface of the tip is waxed,
Sufficient water resistance is also provided to the cut end surface of the laminated paper at the joint portion of the trunk wall.

The paper cup 15 according to the present invention uses the above-mentioned laminated paper not only for the side wall 16 but also for the bottom 17. Therefore, when sealing with a non-permeable lid, the laminated paper 10 used for the cup is A synthetic resin thin film 13 with low gas permeability is interposed as an intermediate layer to prevent oxygen-containing gas from permeating into the vent.

Therefore, when using this container, it has many advantages such as a beautiful appearance, high rigidity of the top, prevention of oxidation of stored articles, and relatively low cost.

As mentioned above, in the paper cup according to the present invention, the inner surface of the body wall 16 and the upper surface of the bottom 17, which are the inside of the container, are coated with the wax layer 14, the paper layer 12, the synthetic resin surface 13, and the paper layer whiter than the paper layer from the inside. Since it is a laminated structure paper cup, which is characterized by a structure in which paper layers 11 of high strength and printability are sequentially laminated, it has a great advantage of preventing oxidation of stored articles.
