Abstract
The utility model discloses a polypropylene/thermoplastic elastomer combined cover which comprises an outer cover and a plug part, wherein the outer cover is connected with a bottle mouth; the plug part can be used for sealing up the bottle mouth; the plug part is positioned in the center inside the outer cover; the top surface, i.e. a punching surface, of the plug part is fixedly provided with a protective film; and the outer cover, the plug part and the protective film are integrated into one whole body. The polypropylene/thermoplastic elastomer combined cover has simple manufacturing process. Therefore, the pollution is reduced, and the manufacturing cost is also greatly reduced. The polypropylene/thermoplastic elastomer combined cover is not provided with an inner cover, so that the punching desquamation performance is good. The protective film is adopted to replace an easily pulled ring. The pollution of polypropylene particles to a medicament is avoided. The quality of liquid medicine in an infusion bottle/bag can be well ensured.
Description
Technical field:
This utility model relates to a kind of polypropylene/thermoplastic elastomer (TPE) composite cover, belongs 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 purpose of this utility model is to provide a kind of polypropylene/thermoplastic elastomer (TPE) composite cover, does not have inner cap, and acupuncture exfoliation performance is better; Its elastomeric material and lid 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.
This utility model technical solution problem 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, the beneficial effects of the utility model are embodied in:
Composite cover of the present utility model 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 this utility model composite cover.
Fig. 2 is the vertical view of this utility model composite cover.
Number in the figure: 1 enclosing cover, 2 plug bizets, 3 protecting film, 4 tear handle.
Below pass through the specific embodiment, and the utility model is described in further detail 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, and described enclosing cover is an integral structure with plug bizet and protecting film.
Concrete manufacturing process: at first; produce enclosing cover 1 by the polypropylene injection machine; the raw material of enclosing cover adopts a kind of in polyethylene (being called for short PE) or the polypropylene (being called for short PP); the injection thermoplastic elastic material forms plug bizet 2 in the lid of enclosing cover then; plug bizet 2 and the bonding integral body that becomes of enclosing cover; injection and adhesion process are finished in mould; at last; directly cover one deck aluminium foil or polypropylene film formation protecting film 7 at the acupuncture face of plug bizet 2 by heat seal or bonding mode; all one steps of production process finish, and cause contaminated probability to reduce greatly.
The plug bizet can be round structure, rectangular structure, three or two branch body structures, and plug bizet (thermoplastic elastic material) directly contacts with medicinal liquid, and the medicinal liquid bottleneck is sealed.
Claims (2)
1. polypropylene/thermoplastic elastomer (TPE) composite cover, it is characterized in that, 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.
