The outer cover of the combined cover is made of a polypropylene material; a puncturing part is made of a thermoplastic elastomer material; the outer cover and an elastomer are bonded into a whole body; the puncturing surface of the combined cover is provided with the protective film which is provided with a tearing handle and is made of an aluminum foil or a polypropylene film; and the aluminum foil or the polypropylene film can be arranged on the cover body through heat sealing or can be directly adhered to the cover body.
Description
Technical field:
The present invention relates to a kind of polypropylene/thermoplastic elastomer (TPE) composite cover and preparation method thereof, belong to technical field of medicine packaging.
Background technology:
Sealing and deriving of soft bag/mould bottle transfusion is different from traditional vial, realizes by " composite cover " mode.Traditional " composite cover " is to combine by " inner cap+rubber cushion+enclosing cover ", because the existence of inner cap, causes that the acupuncture resistance is big, the exfoliation amount is big; It will tear pull-tab off when using, and can produce the pollution of polypropylene microparticle; After its production simultaneously will be carried out inner cap, enclosing cover, rubber sheet gasket earlier, assemble by the heat seal mode, its process is various, easily pollute and the manufacturing cost height again.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of polypropylene/thermoplastic elastomer (TPE) composite cover and preparation method thereof, composite cover of the present invention does not have inner cap, and acupuncture exfoliation performance is better; Its elastomeric material and outer cover are sticking to be integral body, reduced the leakage probability; Adopt protecting film to substitute pull-tab, stopped the pollution of polypropylene microparticle, the quality of the bottle/bag inner liquid medicine of can guaranteeing better to infuse to medicament.
Technical solution problem of the present invention adopts following technical scheme:
A kind of polypropylene/thermoplastic elastomer (TPE) composite cover, comprise the enclosing cover that is connected with bottleneck and the plug bizet that can seal bottleneck, described plug bizet is in the central interior of described enclosing cover, end face at described plug bizet is that acupuncture face is installed with layer protecting film, and described enclosing cover is an integral structure with plug bizet and protecting film;
Described enclosing cover is made by polyethylene or polypropylene, and described plug bizet is made by thermoplastic elastic material.
Described protecting film is aluminium foil or polypropylene film.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Composite cover of the present invention is by enclosing cover, plug bizet and one-body molded formation of protecting film three parts, and its production process can be finished in a step, also greatly reduces manufacturing cost when reducing the liquid medicine contamination probability; Do not have inner cap, the plug bizet adopts thermoplastic elastic material to make, and not only the acupuncture exfoliation is few, has also reduced the leakage probability; Adopt aluminium foil to substitute pull-tab, stopped because of tearing the pollution of polypropylene microparticle that draw ring causes to medicament.
Description of drawings:
Fig. 1 is the structural representation of composite cover of the present invention.
Fig. 2 is the vertical view of composite cover of the present invention.
Number in the figure: 1 enclosing cover, 2 plug bizets, 3 protecting film, 4 tear handle.
Below pass through the specific embodiment, and the invention will be further described in conjunction with the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1,2; the polypropylene of present embodiment/thermoplastic elastomer (TPE) composite cover; comprise the enclosing cover that is connected with bottleneck 1 and the plug bizet 2 that can seal bottleneck; described plug bizet 2 is in the central interior of described enclosing cover 1; end face at described plug bizet is that acupuncture face is installed with layer protecting film 3; protecting film has the handle of tearing 4, and described enclosing cover is an integral structure with plug bizet and protecting film.
Concrete manufacturing process: first method adopts double coloured plastic injection machine, and step is as follows:
A, double coloured plastic injection machine are annotated for No. 1 and are added polypropylene PP in the tube, and plasticizing;
B, double coloured plastic injection machine are annotated tube for No. 2 and are added thermoplastic elastic material and plasticizing;
C, the injection of injection machine matched moulds:
---described annotated tube notes mouth for No. 1 and inject PP in mould, makes the composite cover outer cover;
---described annotated tube for No. 2 and annotates mouth to the central interior position injection thermoplastic elastic material of having annotated outer cover;
D, pressurize/cooling;
E, die sinking;
F, take out the product mix lid from the mould of annotating tube for described No. 2;
G, again with mould Rotate 180 °; PP manufacturing outer cover is annotated in the notes mouth continuation of described No. 1 notes, and described No. 2 a notes notes mouth inject thermoplastic elastic material to the central interior position of having annotated outer cover;
H, matched moulds injection; Annotate mouth continuation notes PP manufacturing outer cover described No. 1, described No. 2 notes tube notes mouths are to the central interior position injection thermoplastic elastic material of having annotated outer cover;
Repeat the operation of C-H item, realize continuous production;
I, protecting film are bonding: a, protecting film is sticked at combination lid end face by the heat seal mode; B, protecting film are adhered to combination lid end face by binding agent.
So-called injection mo(u)lding is meant, the injection of material of heating and melting is injected in the mould, via cooling with solidify after, obtain the method for formed products; The double coloured plastic injection machine characteristics are that an injection machine is furnished with two cover injecting systems, use two supporting molds, in order to make the product that two kinds of different materials constitute;
Second method adopts monochromatic injection machine, and step is as follows:
A), monochromatic injection machine is annotated and is added polypropylene PP in the tube, and plastifies;
B), injection machine matched moulds injection:
---annotate mouth injects PP in mould, make the composite cover outer cover;
C) pressurize/cooling;
D) die sinking;
E) take out product composite cover outer cover from mould;
Repeat the operation of B-E item, realize continuous production;
