Abstract
The utility model relates to a puncture plug dropping-prevention aluminum-plastic combination cover, which is provided with a plastic cover and an aluminum cover, wherein plastic cramps are circularlydistributed on the central position at the inner side on the surface of the plastic cover, the middle part on the surface of the aluminum cover is provided with a circular hole which is shealthed with the plastic cramps, the plastic cover and the aluminum cover can be fixed together by bending outwards a small plastic block, and the inner side on the surface of the aluminum cover is provided witha circular ring which extends out of the cover surface. When in use, the circular ring at the inner side of the aluminum cover can tightly compress a rubber plug on a bottle mouth, so that the rubberplug can be prevented from being pushed into the bottle mouth during the puncture, and the safety of the drug can be improved.
Description
Affiliated technical field
This utility model relates to a kind of aluminium-plastic cap that is used for sealed glass jars, especially a kind of aluminium-plastic cap that can prevent effectively that plug comes off when puncture.
Background technology
More glass containers in the present pharmaceuticals industry adopts plug to add aluminium-plastic cap and encapsulates, aluminium-plastic cap is made up of aluminium lid and vinyl cover, utilize aluminium-plastic cap plug can be fixed on bottleneck, to prevent that plug from skidding off bottleneck, strengthened sealing, but the capping of the aluminium lid that uses is planar configuration now, friction to plug plug face is less, thereby aluminium lid is less to the pressure of plug in use to make this aluminium-plastic cap, can not well the plug face of plug be fixed, when the removal vinyl cover punctures, the plug face of plug very easily is out of shape, and some plug faces are than thin plug even can be advanced in the bottleneck generation plug obscission by needle point, cause liquid contamination, though and the thicker plug of those plug faces is difficult for taking place the plug obscission, its production cost is also higher, and this has also improved product cost to a certain extent, increase the expense expenditure of consumer, be unfavorable for creating conservation-minded society.
Summary of the invention
In order to solve existing aluminium-plastic cap existing problems, this utility model provides a kind of anti-puncture plug aluminium-plastic cap that comes off, this aluminium-plastic cap not only can be well fixing plug, and can carry out well fixingly equally to the thin plug of those plug faces, can prevent effectively that plug from coming off when puncture.
The technical scheme that its technical problem that solves this utility model adopts is: be made up of in the plastic-aluminum composite cover aluminium lid and vinyl cover, the rounded plastics cramp that is distributed with in the inboard center of vinyl cover capping, be provided with at the middle part of aluminium lid capping can with the circular hole of plastics cramp fit, the outside crimping of plastics fritter can be fixed together vinyl cover and aluminium lid, be provided with the annulus that protrudes from capping in the inboard of aluminium lid capping, this annulus in aluminium lid from circular hole to the capping of lid the body, with circular hole be concentric circular.During use,, and then improved the friction of aluminium lid, effectively prevented the problem that plug deforms or comes off when puncture plug plug face because this annulus protrudes from the capping of aluminium lid, thereby can impose bigger pressure to the plug face of plug in the annulus position.
The beneficial effects of the utility model are: in fixing plug, can prevent effectively that plug from deforming or come off when puncture, improve the safety of medicine, product structure is simple, and can effectively reduce the plug cost.

Code description among the figure: 1-covers body; The 2-annulus; 2 '-annulus; The 3-capping; The 4-circular hole; The 5-vinyl cover; 6-plastics cramp.
The specific embodiment
At Fig. 1, among Fig. 2, vinyl cover (5) is fixed together aluminium lid by the plastics cramp (6) that its inboard capping center distributes, as shown in Figure 3, the capping of aluminium lid (3) be provided with can with the circular hole (4) of plastics cramp (6) fit of rounded distribution in the vinyl cover, plastics cramp (6) can fasten aluminium lid capping (3) after hot pressing, medial surface at aluminium lid, to lid body (1), be provided with the annulus (2) that protrudes from capping (3) from circular hole (4), this annulus and circular hole (4) are concentric circular, as shown in Figure 4, annulus (2) position in aluminium lid capping (3) outside is concavity down.In the enforcement, annulus (2) protrudes from the height of aluminium lid capping (3) generally between 2～3 millimeters, distance between annulus (2) and lid body (1) then depends on the thickness of institute's employing vial bottleneck glass, is advisable with the center of the salient point malleation bottle mouth position glass of annulus (2).
In second kind of embodiment shown in Figure 5, on the capping (3) of aluminium lid, be provided with 2 annulus (2), (2 '), to reach the double-layer seal effect, this embodiment can be strengthened the sealing to glass bottle opening.
In the third embodiment shown in Figure 6, be the plane in the outside of the capping (3) of aluminium lid, side then has additional the annulus (2) that protrudes from capping together within it.
Claims (2)
1, a kind of anti-puncture falls to fill in the plastic-aluminum composite cover, form by aluminium lid and vinyl cover, the center of aluminium lid capping is provided with circular hole, and the rounded plastics cramp that is distributed with in the inboard center of vinyl cover capping is characterized in that: be provided with the annulus that protrudes from capping in the inboard of aluminium lid capping.
2, anti-puncture according to claim 1 falls to fill in the plastic-aluminum composite cover, it is characterized in that: annulus on the capping between the lid body from the circular hole to the aluminium lid, with circular hole be concentric circular.
