Description

Curling type paper cup

Technical Field

The utility model relates to a paper container technical field specifically is a turn-up formula paper cup.

Background

The paper cup is a paper container made by mechanically processing and bonding base paper (white paperboard) 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. The present paper cup has a turn-up in rim of a cup department, all adopts circular turn-up at present, see fig. 1 and shows, it can play the effect of certain enhancement rim of a cup, but in the in-service use, easily atress extrusion deformation in the transit, and traditional way all improves on the paper cup material, uses harder paper to make, can play the deformation of preapring for an unfavorable turn of events like this, but too high to the requirement of paper, and the cost is also than higher.

Disclosure of Invention

In order to solve the problem that the existing cup rim is easy to deform and the material replacement cost is high, the utility model provides a curled edge type paper cup, which can strengthen the strength of the cup rim, is difficult to deform and has low cost.

The technical scheme is as follows: the curled edge type paper cup comprises a cup body, wherein an outward curled edge is arranged at the cup opening of the cup body, and the curled edge type paper cup is characterized in that the curled edge comprises an outer side C-shaped section and an inner side inverted L-shaped section, the vertical part of the inner side inverted L-shaped section is tightly attached to the outer wall of the cup opening, the horizontal part of the inner side inverted L-shaped section is tightly attached to the inner side face of the upper end of the outer side C-shaped section, and the thickness of the curled edge is 2.5-3.0 mm.

It is further characterized in that the thickness of the paper of the cup body is 0.40 plus or minus 0.02 mm.

Adopt the utility model discloses afterwards, improved the turn-up structure, increased the area of contact of turn-up, be difficult to leak gas in the cavity that the turn-up formed, greatly increased compressive strength, be difficult to take place to warp, adopt current paper to make can, with low costs.

Drawings

FIG. 1 is a schematic diagram of a prior art paper cup curl;

FIG. 2 is a schematic view of a first curled edge of the present invention;

fig. 3 is a schematic view of a second crimping of the present invention.

Detailed Description

Referring to fig. 2 and 3, the curled-edge type paper cup comprises a cup body, an outward curled edge 1 is arranged at the cup opening of the cup body, the curled edge 1 comprises an outer side C-shaped section 2 and an inner side inverted L-shaped section 3, the vertical part of the inner side inverted L-shaped section 3 is tightly attached to the outer wall of the cup opening, the horizontal part of the inner side inverted L-shaped section 3 is tightly attached to the inner side surface of the upper end of the outer side C-shaped section 2, in order to clearly see the curled edge structure in the figure, a gap exists between the two tightly attached parts, the two tightly attached parts are actually tightly attached together, and the thickness d of the curled edge is 2.5-3. The paper thickness of the cup body is 0.40 +/-0.02 mm.

The utility model discloses in give two kinds of structures, one kind is the turn-up outside for the cambered surface, and another kind is the plane, and the contact sensation can be better some when the cambered surface is to the use.

The utility model discloses in, the turn-up changes the back, has increased the area of contact of turn-up, is difficult to leak gas in the cavity that the turn-up formed, greatly increased compressive strength, the deformation can not appear in the transportation.

Claims

1. The curled edge type paper cup comprises a cup body, wherein an outward curled edge is arranged at the cup opening of the cup body, and the curled edge type paper cup is characterized in that the curled edge comprises an outer side C-shaped section and an inner side inverted L-shaped section, the vertical part of the inner side inverted L-shaped section is tightly attached to the outer wall of the cup opening, the horizontal part of the inner side inverted L-shaped section is tightly attached to the inner side face of the upper end of the outer side C-shaped section, and the thickness of the curled edge is 2.5-3.0 mm.

2. A hemmed paper cup according to claim 1, wherein the paper thickness of the cup body is 0.40 ± 0.02 mm.
