AI Technical Summary
Liquid tends to leak from the spout of existing beverage cups after the lid is torn off directly, leading to waste and staining of clothes.
It adopts a double-layer lid design, with the lower film fixed to the cup body. The through hole is designed on the lower film. The bonding force between the upper and lower films is less than that between the lower film and the cup body. The tear-off part is set on the upper film, and the fixation is achieved by dotted heat fusion.
This allows liquid to flow into the mouth through the lower membrane orifice, preventing it from flowing out of the mouth and making it more convenient to use.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of beverage packaging, in particular to the technical field of cup body. BACKGROUND
[0002] The yogurt, jam beverage and other beverages are sometimes made into cup packaging, generally a layer of cover film is fixed on the top of the cup body, when the beverage in the cup is needed to be consumed, there are two ways: one is to use a pipe to pierce the cover film and use the pipe to suck; the other is to tear the cover film and directly drink with the cup body, when the second way is used, sometimes the liquid in the cup will flow out from the mouth because the cup mouth is too large, which not only causes waste, but also easily dirties the clothes or the floor, and the use is inconvenient. SUMMARY
[0003] The utility model discloses a cup body using double-layer cover film, which can make the lower film still firmly combined with the cup body after the upper film is torn, and the liquid can flow into the mouth through the through hole in the lower film, so the liquid is not easy to flow out from the mouth, and the use is convenient.
[0004] To achieve the above object, the utility model provides a cup body using double-layer cover film, which comprises a cup body and a film cover, the top end of the cup body is open, the film cover is fixed on the top end of the cup body, the film cover is composed of an upper film and a lower film, the lower film is fixed on the top end of the cup body, the lower film completely covers the top end of the cup body, the lower film is provided with a through hole, the upper film is fixed on the upper end face of the lower film, the upper film completely covers the lower film, the bonding force between the upper film and the lower film is less than the bonding force between the lower film and the cup body, the upper film comprises at least one tear-off part, and the lower end face of the tear-off part is not covered by the lower film.
[0005] Preferably, the top end edge of the cup body is provided with a cup rim protruding outward, and the film cover is fixed with the cup rim.
[0006] Preferably, the upper film is a PET film or a composite film composed of a PET film and an aluminum film or a composite film composed of a PET film and paper.
[0007] Preferably, the lower film is a PET film or a PE film.
[0008] Preferably, the upper film and the lower film are fixed by a wave dot type hot melt bonding mode, and the lower film and the cup body are fixed by a hot melt bonding mode.
[0009] Preferably, the through hole is in the shape of a water drop, and the through hole is close to the top end edge of the cup body.
[0010] The utility model discloses a beneficial effect: the utility model discloses a film cover that is fixed on the cup body by the upper film and lower film, and the binding force between the upper film and lower film is less than the binding force between the lower film and cup body, so that the upper film can be separated from the lower film conveniently and the lower film is not easy to separate from the cup body, liquid can flow into the mouth through the through hole on the lower film, and it is not easy to flow out from the mouth, and the utility model discloses convenient to use.
[0011] The features and advantages of the utility model will be described in detail with examples and drawings. DRAWINGS
