Summary of the invention
Object of the present invention is exactly provide a kind of plastic film cup of in-mold label injection mo(u)lding to overcome defect that above-mentioned prior art exists, biscuit, pulvis food product can be widely used in, there is good sealing property, and can repeatedly seal, easy to use, health, ensures the security reliability of product.
Object of the present invention can be achieved through the following technical solutions:
A kind of plastic film cup of in-mold label injection mo(u)lding, it is characterized in that, comprise the first in-mold label film, the second in-mold label film and plastic stent, described plastic stent comprise to bond with the first in-mold label film form cup body cup body brace rod part, bond the bowl cover part that forms bowl cover and the connection tie for being connected glass body and bowl cover with the second in-mold label film.
The cup body brace rod part of described plastic stent is provided with back-off own, and described plastic stent bowl cover part is provided with the bowl cover back-off corresponding with back-off own, and after bowl cover is connected with cup body, described back-off own and bowl cover back-off are connected together and seal.
Described plastic stent also comprises and welds boss with the film welded bowl cover of the second in-mold label.
Described plastic stent also comprises the tearable mouth be located on bowl cover;
During use, first that tearable mouth is upwards cocked, tearable mouth oral area is out of shape, and is started by whole bowl cover, and under the bowl cover part of plastic stent drives, the second described in-mold label film welds boss with bowl cover and is separated.
Described plastic stent also comprises being located at the bottom of glass cup of body brace rod section bottom and stacks boss.
Described cup body brace rod part is engraved structure.
The first described in-mold label film is the film that PE polyethylene material or PP polypropylene material are made.
The second described in-mold label film is the film that PE polyethylene material or PP polypropylene material are made.
Operation principle of the present invention is as follows:
Plastic film cup of the present invention is by in-mold label technology: during injection moulding, first in-mold label film is rolled into cup-shaped by manipulator and is placed on mould inside, the cup body brace rod part of plastic stent is bonded together by injection moulding process and the first in-mold label film, forms a cup body; Second in-mold label film is placed on mould inside by manipulator, and the bowl cover part of plastic stent is bonded together by injection moulding process and the second in-mold label film, forms a lid.Cup body is connected tie with bowl cover by the bowl cover of plastic stent and is connected, and becomes a whole product.
Second in-mold label film, after filled product, by bowl cover and cup body being interlocked, being then welded on bowl cover welding boss by hot pressing form, realizing the sealing of whole packaging by this kind of plastic film cup.
During use, first that tearable mouth is upwards cocked, tearable mouth oral area is out of shape, and is started by whole bowl cover, and under the bowl cover part of plastic stent drives, the second in-mold label film and bowl cover weld boss and be separated, and lid is opened.
After using, pushed back by bowl cover with it cup, under the effect of cup body back-off and bowl cover back-off, bowl cover can be fastened, and whole packaging will have certain sealing.
Compared with prior art, the present invention has the following advantages:
1, material is saved: replace an original whole plastic cup with the plastic stent of hollow out, farthest decrease the consumption of plastics, more environmental protection.
2, two parts one-shot formings: in invention, all parts are an in-mold label injection mo(u)lding, decrease the cost of injection moulding and assembling.
3, can Reusability, much cleaner, more convenient: product itself, with the lid that can repeatedly fasten, has certain sealing, and adaptable food is wider, use also more healthy and convenient.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in figs. 1-7, this kind of plastic film cup is by in-mold label technology: during injection moulding, first in-mold label film 2 is rolled into cup-shaped by manipulator and is placed on mould inside, the cup body brace rod part 8 of plastic stent 1 is bonded together by injection moulding process and the first in-mold label film 2, forms a cup body; Second in-mold label film 3 is placed on mould inside by manipulator, and the bowl cover part of plastic stent 1 is bonded together by injection moulding process and the second in-mold label film 3, forms a lid.Cup body is connected tie 7 with bowl cover by the bowl cover of plastic stent 1 and is connected, and becomes a whole product.
Second in-mold label film 3, after filled product, by bowl cover and cup body being interlocked, being then welded on bowl cover welding boss 10 by hot pressing form, realizing the sealing of whole packaging by this kind of plastic film cup.
During use, first that tearable mouth 4 is upwards cocked, tearable mouth 4 oral area is out of shape, and is started by whole bowl cover, and under the bowl cover part of plastic stent 1 drives, the second in-mold label film 3 and bowl cover weld boss 10 and be separated, and lid is opened.
After using, pushed back by bowl cover with it cup, under the effect of cup body back-off 5 and bowl cover back-off 6, bowl cover can be fastened, and whole packaging will have certain sealing.
