Cup body and opening mechanism capable of opening plastic sealing film conveniently

Abstract

The invention discloses a cup body capable of opening a plastic sealing film conveniently. The cup body comprises the cup body, the plastic sealing film is arranged at the upper end of the cup body ina plastically sealed mode, and a plurality of grooves are evenly formed in the outer side wall of the cup body. The invention further discloses an opening mechanism capable of opening the plastic sealing film conveniently. The opening mechanism comprises a fixing cover, a plurality of protrusions are arranged on the inner side wall of the fixing cover uniformly, and each protrusion is arranged ina corresponding groove in a clamped mode; a rotating cover is disposed on the fixed cover a clamped mode, a plurality of arc-shaped clamping grooves are formed in the rotating cover uniformly, and each of the arc-shaped clamping grooves is internally provided with a rotating ball in a clamped mode; the fixing cover is provided with an arc-shaped ring groove, and the rotating balls are located inthe arc-shaped ring groove; and a T-shaped ring groove is formed in the inner side wall of the fixing cover. The cup body has the advantages that the structure is ingenious and can effectively solve the situation that plastic sealing films are not easy to open in daily life, the cup body opening mechanism of the same size specification can be reused, and resources and costs are saved.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a cup body and an opening mechanism for easy opening of a plastic film. Background technique [0002] Liquid foods such as jelly are often affixed with a plastic film on the mouth of the bottle in order to avoid contact between the inside and the outside air and prolong the shelf life of the product. Some food manufacturers excessively increase the heat-sealing temperature, pressure or time in order to ensure that the heat-sealing between the plastic film and the cup body is firm, so that the heat-sealing of the plastic film is excessive and the heat-sealing strength is too large, so that the heat-sealing between the plastic film and the cup body is firm , However, the plastic sealing film is not easy to open, and it is also easy to cause the plastic sealing film to break at the root of the sealing edge, which is not convenient for users to use. [0003] Therefore, we ...
