Embodiment
[0033] refer to Figure 1-5 , a cup body that is easy to open the plastic film, including a cup body 1, the upper end of the cup body 1 is plastic-sealed with a plastic film film 3, and a plurality of grooves are evenly opened on the outer wall of the cup body 1, so as to facilitate cooperation with the corresponding opening mechanism .
[0034] An opening mechanism for easy opening of the plastic film, including a fixed cover 2, the fixed cover 2 is made of polypropylene material, has a certain degree of elasticity, drives the protrusion 9 to be stuck in the groove, and can be restored to its original shape, and at the same time, it is resistant to high temperature and easy to clean To be reused after disinfection, a plurality of protrusions 9 are evenly provided on the inner side wall of the fixed cover 2, and each protrusion 9 is clamped in a corresponding groove.
[0035] The fixed cover 2 is provided with a rotating cover 6, and the rotating cover 6 is evenly provided wi...

The invention discloses a cup body which is easy to open a plastic sealing film. The invention also discloses an opening mechanism for easy opening of the plastic film, which includes a fixed cover, a plurality of protrusions are uniformly arranged on the inner side wall of the fixed cover, and each protrusion is clamped in a corresponding groove Inside; the fixed cover is clamped with a rotating cover, and a plurality of arc-shaped slots are evenly opened on the said rotating cover, and a rotating ball is clamped in each of the arc-shaped slots, and a rotating ball is set on the fixed cover. There is an arc-shaped ring groove, and each rotating ball is located in the arc-shaped ring groove; a T-shaped ring groove is opened on the inner side wall of the fixed cover. The advantages are: the structure of the present invention is ingenious, which can effectively solve the problem that the plastic film is not easy to open in daily life, and the opening mechanism for the same size cup can be reused, saving resources and costs.
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 ...
