Abstract

The utility model discloses a thermal-insulation paper tank and paper cap, comprising an inner layer and a PE layer on the inner surface of the inner layer. The utility model is characterized in that the exterior of the inner layer is provided with an outer layer, the upper and lower edges of both the outer layer and the inner layer are stuck together, with a gap reserved between the inner layer and the outer layer for the forming of an air layer. The thermal-insulation paper tank and paper cap are not only thermal insulating but also thermal preservation and therefore can be used as a bowl for packing instant foods such as instant noodles or as a disposable water cup.

Description

Sheathing paper bucket, dixie cup

(1) technical field

The utility model relates to a kind of disposable rice bowl or drinking-water cup.Be instant noodle bowl or teacup specifically with heat insulating function.

(2) background technology

In the packaging for foodstuff industry, the rice bowl that is used for packaged convenience food such as instant noodles mostly is to make with expanded material (PSP).Owing to contain toxic substance in the expanded material (PSP), do not degrade, can pollute environment after abandoning.Therefore, forbidden by national governments just gradually, what replace then is papery rice bowl or teacup.Because papery rice bowl or teacup have nontoxic, readily degradable energy, extensively be used on the packing of instant noodles and on the teacup of drinking-water usefulness.

At present, papery rice bowl of being sold on the market or teacup all are single layer structures, after pouring hot water into, not only soup hand, and rapid heat dissipation, are not incubated.

(3) summary of the invention

The purpose of this utility model is to provide a kind of sheathing paper bucket, dixie cup.This sheathing paper bucket, dixie cup, not only soup hand not, and insulation.

For achieving the above object, the utility model adopts following technical solution:

Sheathing paper bucket of the present utility model, dixie cup comprise internal layer, and the inside face of internal layer has the PE layer.There is skin the outside that is characterized in internal layer, and the upper and lower limit of this outer field upper and lower limit and internal layer bonds together, and inside and outside interlayer leaves the gap that is used to form air layer.

Adopt such scheme, have the following advantages:

Because sheathing paper bucket of the present utility model, dixie cup, there is skin its internal layer outside, and inside and outside interlayer leaves the gap that is used to form air layer.During use, pour hot water into after, heat distributes slowlyer, temperature retention time is long.Be useful on the gap of formation air layer again owing to inside and outside interlayer, can the soup hand during with the hand end.

(4) description of drawings

Accompanying drawing is sheathing paper bucket of the present utility model, dixie cup structural representation.

(5) specific embodiment

See accompanying drawing, sheathing paper bucket of the present utility model, dixie cup comprise internal layer 1, and this internal layer is paper bucket or the dixie cup main body made from pure wood pulp, is compounded with one deck PE layer on its inside face, to be used to prevent seepage.It is outer 2 that the outside of internal layer 1 is provided with, and this skin is to form with sheet processing such as white duplex board, ash edition paper, art paper or craft papeies, and its upper and lower edge bonds together with the upper and lower edge of internal layer 1 respectively.Internal layer stacked 1 and 2 of skins leave the gap, so that form heat-insulating air layer 3.Wherein, internal layer 1 and outer 2 s' gap becomes big from top to bottom gradually.Outer 2 following inside curling is so that form crimp 4.Said crimp 4 can be circle, semicircle or triangle etc.

Claims

1. sheathing paper bucket, dixie cup, comprise internal layer (1), the inside face of internal layer (1) has the PE layer, there is skin (2) outside that it is characterized in that internal layer (1), this outer field upper and lower limit bonds together with the upper and lower limit of internal layer (1) respectively, leaves the gap that is used to form air layer (3) between internal layer (1) and outer (2).

2. sheathing paper bucket according to claim 1, dixie cup is characterized in that said skin (2) for more than two-layer, and each skin also leaves the gap that is used to form air layer (3) between (2).

3. sheathing paper bucket according to claim 1 and 2, dixie cup is characterized in that the oriented interior crimp (4) that curls in skin (2) lower edge.

4. sheathing paper bucket according to claim 3, dixie cup is characterized in that said crimp (4) is for circular.

5. sheathing paper bucket according to claim 3, dixie cup is characterized in that said crimp (4) is for semicircle.
