Description

Paper pulp moulding tableware without plastic heat sealing

Technical Field

The utility model relates to the technical field of molded tableware, in particular to plastic-free heat-seal paper pulp molded tableware.

Background

The traditional paper pulp molding tableware is required to be subjected to plastic film coating on the original basis to finish sealing and sealing, and the tableware subjected to film coating is sealed and sealed with a plastic film or a film-coated paper film, so that soup is prevented from overflowing, and a heat preservation effect is achieved. However, the plastic composite film is generally not degradable, can not be heated by a high-temperature microwave oven, is limited in application range, and is easy to pollute the environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a non-plastic heat-seal pulp molding tableware.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the paper pulp molding tableware without plastic heat sealing comprises a tableware body, wherein a waterproof layer is arranged on the outer side of the tableware body, sealing paper is arranged at an opening at the upper end of the tableware body, an inner ring and an outer ring are arranged on the lower end face of the tableware body, the inner ring and the outer ring are identical in height, reinforcing ribs which are uniformly distributed are connected between the inner ring and the outer ring, the upper ends of the reinforcing ribs are connected with the bottom surface of the tableware body, the height of each reinforcing rib is smaller than that of the inner ring, and a lug is arranged at the lower end of each reinforcing rib.

Preferably, the tableware body, the inner ring, the outer ring, the reinforcing ribs and the bumps are integrally formed.

Preferably, the number of the reinforcing ribs is 4-8.

Preferably, the bump is a hemispherical bump.

Preferably, a waterproof layer is arranged between the tableware body and the sealing paper.

The utility model has the beneficial effects that:

1. the waterproof layer is sprayed on the surface of the tableware body, so that the film coating process is reduced, the cost is reduced, the use of plastics is reduced, and the environment is not easily polluted.

2. After the tableware body is sealed by the sealing paper, the heat preservation effect of the tableware body is better, the liquid can be completely sealed without overflowing, and the tableware is suitable for being used in various restaurants, take-out shops and fruit and beverage shops.

3. The inner ring, the outer ring, the reinforcing ribs and the convex blocks are matched, the tableware body can be supported, large gaps exist among the inner ring, the outer ring, the reinforcing ribs and the convex blocks, materials are few, and cost is effectively saved.
