Description
Technical Field
The invention relates to a paper cup cover, in particular to a production process of an outer buckle type paper cup cover.
Background
The paper cup can be used for containing hot drinks or cold drinks such as coffee, milk and the like, and is generally covered with a cup cover when in use. In the prior art, after the cup cover covers the paper cup, the cup cover can easily fall off due to carelessness, so that drinks in the cup can easily leak out to cause scalding or dirtying clothes; in addition, the cup cover is not tight in sealing the paper cup, so that leakage of the beverage in the cup is easy to cause when the cup is shaken, and the use is affected.
Disclosure of Invention
In view of the defects of the prior art, the technical problem to be solved by the invention is to provide a production process of an externally buckled paper cup cover, and the externally buckled paper cup cover produced by the process can effectively prevent the cup cover from falling off and ensure the internal sealing reliability of the cup when being combined with a paper cup with an inner sill for use.
The invention is implemented by the following technical scheme:
the production process of the outer buckled paper cup cover is characterized in that: the method comprises the following steps of a, preparing a round sheet stock for producing the paper cup cover; b. the periphery of the circular sheet material is bent downwards to form the outer edge of the cup cover, and the part, which is not bent, in the middle of the circular sheet material becomes a cup cover body; c. the bottom of the outer edge of the cup cover is bent upwards to form a cup cover folded bottom; d. the middle of the cup cover body is bent downwards to form a sinking step; e. preparing a circular inner buckling paper sheet; f. the inner buckling paper sheet is adhered to the bottom of the sinking step and has certain eccentricity with the cover body of the cup cover.
The production process of the outer buckled paper cup cover also comprises the following steps of extruding and forming an annular buckling groove on the side wall of the outer edge of the cup cover.
The production process of the externally buckled paper cup cover also comprises the following step of reshaping the folded bottom of the cup cover after the folded bottom of the cup cover is finished.
The outer buckled paper cup cover produced by the process can effectively prevent the cup cover from falling off and ensure the internal sealing of the cup to be reliable when being combined with the paper cup with the inner bank, and the working principle is as follows: the cup cover comprises a cup cover body and a cup cover body, wherein a sunken step is arranged in the center of the top of the cup cover body, and an inner buckling paper sheet is adhered to the bottom of the sunken step; meanwhile, the other end of the inner buckled paper sheet can be separated from the inner bank of the paper cup, so that the paper cup cover can be conveniently taken down from the paper cup by slightly exerting force on the corresponding end of the paper cup cover, and the normal use of the paper cup and the paper cup cover is not influenced. In addition, the outer edge of the cup cover is provided with the annular buckling groove, when the paper cup cover covers the cup opening of the paper cup with the inner bank, the annular buckling groove can buckle the cup opening curled edge of the paper cup with the inner bank from the outer side direction, the buckling effect between the paper cup and the paper cup cover is effectively improved, and the sealing reliability is guaranteed.
