Abstract

The utility model provides a combined cap for a soft bag or a plastic bottle, which comprises a cap body and an elastic seal body arranged in the cover body. The cap body is adhered with the elastic seal body into a whole and a removable protective film covers the puncturing surface of the cap body. A tearing handle is arranged on the removable protective film. The combined cap adopts a plastic casing, an elastic body puncture part and the protective film in the structure, has simple manufacturing process, reduces the pollution and also reduces the manufacturing cost; meanwhile, as no inner cap is used, the required puncturing force is small and the dropped chip during puncturing is less; the elastic seal material is adhered with the cap body into a whole for eliminating the possibility of liquid leakage; the protective film is adopted to replace a pull ring and is coordinated with the tearing handle to realize convenient operation, and the contamination of the plastic particles to the medicament is eliminated, and the quality of the liquid medicine in the transfusion/bag is better ensured.

Description

Soft bag or mould the bottle composite cover

Technical field

This utility model relates to a kind of fluid delivery apparatus parts, particularly a kind of composite cover that is used for soft bag or plastic infusion bottleneck.

Background technology

Traditional " composite cover " is to combine by " inner cap+rubber cushion+enclosing cover " in the transfusion device, because the existence of inner cap, causes that the acupuncture resistance is big, the exfoliation amount is big; Pull-tab to be torn off during use, the pollution of plastic particles can be produced; Manufacture process is after will carrying out inner cap, enclosing cover, rubber sheet gasket earlier, to assemble by the heat seal mode again, and its process is various, easily pollute and the manufacturing cost height.

Summary of the invention

The purpose of this utility model is to provide a kind of manufacture process simple, also greatly reduces manufacturing cost when reducing to pollute; Acupuncture power is little, the acupuncture exfoliation is few; Good airproof performance is operated soft easily bag or is moulded the bottle composite cover.

The purpose of this utility model is achieved in that a kind of soft bag or moulds bottle and use composite cover, comprises lid, is provided with elastic sealed body in the lid, and lid and elastic sealed body are bonded as one, are coated with on the puncture face of lid easily to tear protecting film.Easily tearing protecting film is provided with and tears handle.

Easily tear protecting film and be aluminium foil, plating and mould a kind of in aluminium foil, PP film, PE film, PVC film, PET film or the PP TYPE.

Elastic sealed body adopts a kind of in styrene analog thermoplastic elastomer, polyolefins thermoplastic elastomer, polyurethanes thermoplastic elastomer (TPE), polyesters thermoplastic elastomer (TPE), thermoplastic polyamide elastomer, ethylene copolymer thermoplastic elastomer (TPE), 1,2 polybutadiene thermoplastic elastomer (TPE), using trans-polyisoprene thermoplastic elastomer (TPE), thermoplastic elastomer of polyvinyl-chloride, chlorinated polyethylene thermoplastic olefinic elastomer, polysiloxanes analog thermoplastic elastomer, thermoplastic fluorine-containing elastomer or the ion-type thermoplastic elastomer (TPE).

The material of lid is a kind of among PET or PP or the PE.

This utility model provides soft bag or mould bottle and use composite cover, the structure of the plastic casing of employing+elastomer acupuncture portion+protecting film, manufacture process is simple, also greatly reduces manufacturing cost when reducing to pollute; Simultaneously, because it does not have inner cap, acupuncture power is little, the acupuncture exfoliation is few; Elastic packing material and lid are sticking for whole, have stopped the leakage probability; Adopt protecting film to substitute pull-tab, match, operation facility and stopped the pollution of plastic particles, the quality of the bottle/bag inner liquid medicine of can guaranteeing better to infuse to medicament with tearing handle.

The specific embodiment

This utility model comprises lid 1, is provided with elastic sealed body 2 in the lid 1, and lid 1 is bonded as one with elastic sealed body 2, is coated with on the puncture face of lid 1 and easily tears protecting film 3.Easily tearing protecting film 3 is provided with and tears handle 4.

As depicted in figs. 1 and 2 be a kind of technical scheme of the present utility model, tear handle 4 and stick on the lid 1.

As shown in Figure 3 and Figure 4 be another technical scheme of this utility model, it is local outstanding easily to tear handle 4.

As shown in Figure 5 and Figure 6 be the third technical scheme of this utility model, easily tear protecting film 3 film integral body and be overlying on the lid 1.

Easily tear protecting film 3 and be aluminium foil, plating and mould a kind of in aluminium foil, PP film, PE film, PVC film, PET film or the PP TYPE.Easily tearing protecting film 3 sticks at lid 1 by the heat seal mode and also can directly be pasted on lid 1 by binding agent.

Elastic sealed body 2 adopts a kind of in styrene analog thermoplastic elastomers, polyolefins thermoplastic elastomer, polyurethanes thermoplastic elastomer (TPE), polyesters thermoplastic elastomer (TPE), thermoplastic polyamide elastomer, ethylene copolymer thermoplastic elastomer (TPE), 1,2 polybutadiene thermoplastic elastomer (TPE), using trans-polyisoprene thermoplastic elastomer (TPE), thermoplastic elastomer of polyvinyl-chloride, chlorinated polyethylene thermoplastic olefinic elastomer, polysiloxanes analog thermoplastic elastomer, thermoplastic fluorine-containing elastomer or the ion-type thermoplastic elastomer (TPE).
