Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of covering films, in particular to a covering film that can be opened repeatedly. Background Art
[0002] With the continuous advancement and development of science and technology, people have higher and higher requirements for the quality of life. In the packaging industry, in addition to requiring plastic flexible packaging materials to meet the increasing requirements of packaging quality and efficiency of different products, they are also required to save resources and energy.
[0003] At present, when people use some plastic packaging boxes, they often do not finish the food and need to cover the torn cover film. The usual cover film is made of aluminum foil or paper, which makes it difficult to stick the cover film again after it is torn. As a result, the food in the plastic packaging box will deteriorate when placed outdoors or will have a smell when placed in the refrigerator. Therefore, a re-openable cover film is proposed. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a re-openable covering film, which solves the problem that food cannot be finished and the torn covering film needs to be covered again, resulting in the covering film being unable to be glued again after being torn.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a re-openable covering film, comprising a covering film body arranged above the bottle mouth of a packaging box, the covering film body comprising a first covering film, an annular fixed film is arranged at the bottom of one side of the first covering film, the first covering film and the annular fixed film are both fixedly pressed on the top of the bottle mouth of the packaging box, a second covering film is arranged on one side of the first covering film, a folding portion is arranged between the first covering film and the second covering film, and a plurality of pressing portions and bonding portions are arranged at intervals on the top of the annular fixed film.
[0006] Preferably, the bonding portion comprises a film and a first double-sided adhesive layer, the first double-sided adhesive layer is bonded between the film and the second covering film, and the film is fixedly connected to the top of the annular fixing film.
[0007] Preferably, a protruding easy-tear film is fixedly connected to one side of the outer surface of the second covering film.
[0008] Preferably, a second double-sided adhesive layer adapted to the protruding easy-tear film is provided on one side of the outer surface of the bottle mouth of the packaging box.
[0009] Beneficial Effects
[0010] The utility model provides a lidding film that can be opened repeatedly. Compared with the existing technology, it has the following beneficial effects:
[0011] (1) The utility model pulls the second covering film upward so that the second covering film drives multiple pressing parts to be peeled off from the annular fixed film, and then the second covering film is attached to the annular fixed film so that the second covering film is attached to multiple bonding parts. The second covering film is bonded to the multiple bonding parts, so that the second covering film can be conveniently sealed and bonded to the annular fixed film, thereby facilitating repeated opening of the second covering film, and being more convenient to use.
[0012] (2) The utility model uses the protruding tear film on the second covering film to pull the protruding tear film upward, so that the second covering film can be easily pulled, and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] See also Figure 1-6The utility model provides a technical solution: a re-openable covering film, comprising a covering film body 2 arranged above a bottle mouth 1 of a packaging box, the covering film body 2 comprising a first covering film 21, a ring-shaped fixed film 22 is arranged at the bottom of one side of the first covering film 21, the first covering film 21 and the ring-shaped fixed film 22 are both fixedly pressed on the top of the bottle mouth 1 of the packaging box, a second covering film 23 is arranged on one side of the first covering film 21, a folding portion 24 is arranged between the first covering film 21 and the second covering film 23, a plurality of pressing portions 3 and bonding portions 4 are arranged at intervals on the top of the ring-shaped fixed film 22, the bonding portion 4 comprises a film 41 and a first double-sided adhesive layer 42, the first double-sided adhesive layer 42 is bonded between the film 41 and the second covering film 23, and the film 41 is fixedly connected to the top of the ring-shaped fixed film 22.
[0022] It should be noted that the first double-sided adhesive layer 42 and the second double-sided adhesive layer 6 are resin-type pressure-sensitive adhesives, and the film 41 is made of PVC polyvinyl chloride.
[0023] Furthermore, in order to facilitate pulling the second covering film 23 , a protruding tear film 5 is fixedly connected to one side of the outer surface of the second covering film 23 , and a second double-sided adhesive layer 6 adapted to the protruding tear film 5 is provided on one side of the outer surface of the bottle mouth 1 of the packaging box.
[0024] It should be noted that the first covering film 21, the annular fixing film 22, the second covering film 23 and the protruding easy-tear film 5 are all made of food-grade coated paper.
[0025] When in use, the protruding tear film 5 is pulled rightward to peel off the protruding tear film 5 from the second double-sided adhesive layer 6, and then the protruding tear film 5 is pulled upward, the protruding tear film 5 will drive the second covering film 23 to be pulled upward, and the second covering film 23 will drive the multiple pressing parts 3 and the bonding parts 4 to separate from the multiple annular fixed films 22, so that the second covering film 23 is folded and opened from the folding part 24;
[0026] After the second covering film 23 is opened, the contents in the bottle mouth 1 of the packaging box can be taken out. When the bottle mouth 1 of the packaging box needs to be sealed again, the protruding easy-tear film 5 is pulled downward to make the second covering film 23 cover the multiple pressing parts 3 and the bonding parts 4, so that the second covering film 23 is bonded to the multiple bonding parts 4, and at the same time, the protruding easy-tear film 5 is bonded to the second double-sided adhesive layer 6, so that the second covering film 23 is sealed on the annular fixing film 22 again, so that the covering film 2 seals the bottle mouth 1 of the packaging box.
