Abstract
The utility model relates to a film-coating rubber plug with ring sealing ribs of a container used for storing physic liquor. The utility model comprises a top cover and a plug neck connected with the top cover. The utility model is characterized in that at least one protuberant annular sealing rib is additionally arranged on a sealing surface (1) at the lower end of the top cover contacted with the plane surface of a bottle opening. The utility model has the advantage of good sealing property of the film-coating rubber plug and the sealing surface at the lower end of the top cover contacted with the plane surface of the bottle opening.
Description
Technical field:
The utility model relates to a kind of plug.Relate in particular to a kind of compound film rubber cork that has the annular seal muscle that loads the container of medicine.
Background technology:
Plug is the container of filling medicine such as an important sealing member of glass bottle, and plug such as the Fig. 1,2 that widely uses comprises top cover and connected plug neck at present.
Common plug is made by rubber, be the content of minimizing rubber plug and the reaction of medicine, improve the compatibility of medicine and plug, generally all can be laminated with thin film, make compound film rubber cork on the surface or the whole rubber plug surface of rubber plug and medicine direct contact.
Common compound film rubber cork, top cover lower end sealing surface 1 smooth surface that contacts with glass bottle opening, its leak tightness has two major defects:
1, after soup injected and seals in the bottle, sealing surface 1 (Fig. 1,2) was fitted closely because of being subjected to external force and bottleneck.In the process of carrying out steam sterilizing, bottle inner liquid medicine meeting expanded by heating makes pressure of the inside of a bottle greater than ambient pressure.Because the top cover lower end sealing surface smooth surface behind the multiple film, the sealing surface of plug and bottleneck may produce slight loosening, thereby influence the leak tightness of compound film rubber cork.
2, because laminated film is different with the shrinkage percentage of rubber, compound film rubber cork produces the trickle gauffer that runs through sealing surface on sealing surface when being subjected to the external force extruding, and this gauffer also can cause liquid leakage or gas to pass, and influences sealing property.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of compound film rubber cork that has the annular seal muscle that can improve compound film rubber cork and glass bottle leak tightness is provided.
The purpose of this utility model is achieved in that a kind of compound film rubber cork that has the annular seal muscle, comprise top cover and connected plug neck, be characterized in the top cover lower end sealing surface of bottleneck plane contact on increase the annular seal muscle of at least one projection, the face sealing that changes in the past is a linear sealing.
Add a cover sealed after, the oppressed distortion of annular seal muscle, this moment, the sealed muscle local pressure was bigger, even pressure of the inside of a bottle has slight jack-up plug behind the steam sterilizing, but annular seal muscle position still can with the driving fit of bottleneck plane, can effectively prevent to leak; Simultaneously, the tiny gauffer of the generation that is squeezed can not run through whole sealing surface, thereby guarantee its sealing effectiveness owing to the annular seal muscle stops.

Fig. 1 is the structural representation of original plug.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the utility model plug structural representation.
Fig. 4 is the birds-eye view of Fig. 3.
The specific embodiment:
Referring to Fig. 3,4, Fig. 3,4 is a kind of compound film rubber cork that has the annular seal muscle, is made up of top cover and connected plug neck.With the annular seal muscle 2 that increases by at least one projection on the top cover lower end sealing surface 1 of bottleneck plane contact.
Claims (1)
1, a kind of compound film rubber cork that has the annular seal muscle comprises top cover and connected plug neck, it is characterized in that: go up the annular seal muscle (2) that increases by at least one projection with the top cover lower end sealing surface (1) of bottleneck plane contact.
