Abstract

The utility model discloses a thermal-insulated paper cup, including the bottom of cup of circle ring shape wall of cup and sealed this wall of cup bottom, the wall of cup comprises inner wall and outer wall, the outer wall inboard is stained with the insulating layer, the inner wall with filled the fixed folded layer of buckling repeatedly between the insulating layer, the wall of cup outside still overlaps there is the flexible glue glass holder, bottom of cup indent and bottom are stained with the hardpaper layer. The cup wall with the double-layer structure is formed by the inner wall and the outer wall, the cup wall is fixed by the folding layer which is bent repeatedly and has more gaps, the heat insulation layer is additionally arranged on the inner side of the outer wall, the overall heat insulation effect is also improved in the process of reducing heat transfer to the outer side, the soft rubber cup sleeve is prevented from being in direct contact with the cup wall, and the heat insulation performance can be improved.

Description

Heat insulation paper cup

Technical Field

The utility model relates to a cup technical field specifically is a thermal-insulated paper cup.

Background

The paper cup is a paper container made by mechanically processing and bonding base paper made of chemical wood pulp, and the appearance of the paper container is cup-shaped. The paper cup for frozen food is waxed, and can be used for containing ice cream, jam, butter, etc. The paper cup for hot drink is coated with plastic, can resist the temperature of over 90 ℃ and even can contain boiled water. The paper cup is characterized by safety, sanitation, lightness and convenience. The disposable sanitary towel can be used in public places, restaurants and dining rooms and is a disposable article. However, the currently-used paper cup has poor heat insulation effect, is easy to scald hands when containing hot water, has poor experience and is extremely inconvenient to use.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a heat insulation paper cup, which can effectively solve the problem provided by the background technology.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a thermal-insulated paper cup, includes ring shape wall of cup and the bottom of cup of sealed this wall of cup bottom, the wall of cup comprises inner wall and outer wall, the outer wall inboard is stained with the insulating layer, the inner wall with filled the fixed folded layer of buckling repeatedly between the insulating layer, the wall of cup outside still overlaps there is the flexible glue glass holder, bottom of cup indent and bottom are stained with the hard paper layer.

Further, the inner diameter of the upper part of the cup wall is larger than that of the lower part.

Further, the top of the inner wall is bent outwards and tightly attached to the outer side of the outer wall.

Further, the wall of a cup outside is equipped with the card and goes into fixedly the glass holder screens of flexible glue glass holder and indent, the height that highly equals of glass holder screens the height of flexible glue glass holder, the degree of depth of glass holder screens is not more than the thickness of flexible glue glass holder.

Furthermore, vertical stripes are arranged below the cup wall.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a constitute bilayer structure's wall of a cup by inner wall and outer wall to it is fixed by the folding layer of buckling more having the space repeatedly, and the outer wall inboard has added the insulating layer moreover, reducing the in-process in heat transfer to the outside, has also improved holistic thermal-insulated effect, and the flexible glue glass holder prevents to directly touch with the wall of a cup, can improve thermal-insulated performance equally, and overall structure is simple, convenient to use, and the practicality is strong.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides a thermal-insulated paper cup, including the bottom of cup 2 of ring shape wall of cup 1 and sealed this wall of cup 1 bottom, wall of cup 1 comprises inner wall 3 and

outer wall

4, 4 inboards of outer wall are stained with insulating layer 5, inner wall 3 with filled between the insulating layer 5 and buckled fixed folded layer 6 repeatedly, 1 outside of wall of cup has still overlapped flexible

glue glass holder

7, 2 indent of bottom of cup and bottom are stained with hard paper layer 8.

The internal diameter of 1 upper portion of wall of cup is greater than the internal diameter of lower part, 3 tops of inner wall are outwards buckled and are hugged closely 4 outsides of outer wall, 1 outsides of wall of cup is equipped with the card and goes into fixedly the glass holder screens 9 of flexible glue glass holder 7 and indent, the height that highly equals of glass holder screens 9 the height of flexible glue glass holder 7, the degree of depth of glass holder screens 9 is not more than the thickness of flexible

glue glass holder

7, 1 below of wall of cup still is equipped with erects line 10.

Compared with the prior art, this technical scheme has adopted by inner wall 3 and outer wall 4 constitution bilayer structure's cup wall 1 to by buckle repeatedly more having the space folded layer 6 fixed, outer wall 4 inboard has added insulating layer 5 in addition, reduces the in-process of heat transfer to the outside, has also improved holistic thermal-insulated effect, flexible glue glass holder 7 prevents to directly touch with cup wall 1, can improve thermal-insulated performance equally.

During the use, when pouring hot water to the paper cup, the heat of hot water is transferred to outer wall 4 from inner wall 3 gradually, and thermal direct transmission has been prevented owing to there is the space in middle folded layer 6 to spread in the space of folded layer 6, during heat transfer moreover, the outside that insulating layer 5 has protected wall of cup 1 plays thermal-insulated effect, and direct and wall of cup contact and take place to scald one's hand when the flexible glue glass holder 7 on the wall of cup 1 avoids using.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
