Abstract

A combined cover comprises a pressing cover, a sealing ring and a sealing portion. The pressing cover comprises a first annular side wall, a top wall and a second annular side wall, wherein the first annular side wall is arranged on the outer side, the top wall extends at the upper end of the first annular side wall and is provided with an opening, the second annular side wall is arranged on the inner side and connected to the lower surface of the top wall, and the second annular side wall, the top wall and the first annular side wall encircle to form an annular space with a downward opening. The sealing ring is arranged in the annular space, the sealing portion is connected to the opening of the top wall hermetically. The combined cover with the pressing cover and the sealing portion solves the problem that production environment is polluted by aluminum powder generated due to friction between a binder and each aluminum cap when the aluminum cap is bound to a mouth of a vial in a rolling manner in package of vials, and simultaneously solves the problem that medicine safety is affected by particles generated from the rubber plug contacting with drugs in the vials after a period of time of storage, and has the advantages of simple structure and process, low cost and convenience in use.

Description

Composite cover

Technical field

This utility model relates to the medical packaging field, more specifically, relates to a kind of composite cover.

Background technology

Fig. 1 shows existing antibiotic and packs with cillin bottle.As shown in the figure, plug 12 ' in the composite cover 1 ' easily contacts with medicine 3 ' in the bottle 2 ' in transporting procedures, owing to contain compositions such as rubber, vulcanizing agent, vulcanization accelerator, filler, plasticizer, protein molecule in the plug 12 ' composition, after the more intense medicine of some molecular activities contacts, by drug absorption, absorption, leaching, infiltration, produced the consistency problem of plug and medicine, relatively more outstanding is part cephalosporins, part infusion solutions class and more Chinese medicine injection liquid formulation etc., thereby influences drug quality.

In order to address this problem, existing generally adopt glue stopper neck portion (can with medicine contact site in the bottle) surface coverage one deck stable performance, with the good film of drug compatibility, directly contact to prevent medicine with plug.But this plug complex manufacturing, the cost height.

Simultaneously, packing adopts plastic-aluminum gland 11 ' that plug 12 ' and bottleneck are compressed as shown in Figure 1, and when being rolled into bottleneck on knife plastic-aluminum gland 11 ', knife and the 11 ' friction of plastic-aluminum gland produce the aluminium powder bits, pollute production environment.

The utility model content

This utility model aims to provide a kind of composite cover, to overcome above-mentioned defective of the prior art.

Composite cover of the present utility model comprises: the pressing cap comprises: first annular sidewall that is positioned at the outside; Roof extend in the upper end of first annular sidewall, and roof has opening; Be positioned at the second inboard annular sidewall, be connected on the lower surface of roof, surround the annular space that Open Side Down, be provided with sealing ring in the annular space with the roof and first annular sidewall; Sealing is sealedly connected on the opening part of roof.

Further, sealing is foldable handle or easy-to-fold cap or easy broken rod or easily tore film.

Further, second annular sidewall is provided with one or more first flutings that extend vertically.

Further, first annular sidewall is provided with one or more second flutings that extend vertically.

Further, the lower end of first annular sidewall is provided with the inward flange that bends inwards.

Further, the outer surface of the second annular sidewall lower end is provided with chamfered section.

Composite cover of the present utility model has pressing cap and sealing thereof, having solved existing cillin bottle packing exists aluminium lid when roll forming is tightened on the bottleneck, knife and aluminium lid friction produce the aluminium powder bits, pollute the problem of production environment, also solved simultaneously plug and contacted, after storing certain hour, easily produced microgranule, influenced the problem of the safety of medication with a bottle interior medicine, and its structure, technology are simple, and cost is low and easy to use.
