Abstract
The utility model discloses a film-coated rubber plug, which comprises a plug top and a plug neck. A film is coated on the surface of the plug neck, the plug top at the junction of the plug top and the plug neck, and the sealing surface of a bottle opening. Compared with the prior art, the film-coated rubber plug has the following advantages: due to the film coated on plug top at the junction of the plug top and the plug neck and the sealing surface of the bottle opening, the rubber material of the sealing surface of the plug top which may contact with medicinal liquid or medicament is completely isolated from the medicinal liquid or the medicament, so as to prevent mutual dissolution, thereby ensure the medicament quality and human body health; and the film is only coated on the plug top and the sealing surface of the bottle opening at the junction thereof and the plug neck, and most regions of the plug top sealing surface and the bottle opening of a container are not coated with the film, so that the performance of sealing between the rubber plug and the bottle opening of the container can still be ensured.
Description
Technical field
This utility model relates to a kind of plug, relates in particular to a kind of medical overlay film plug that loads the container of medicine.
Background technology
As everyone knows, the overlay film plug is a kind of container of medicine such as vitals of vial of loading, and present widely used overlay film plug cooperates as shown in Figure 1 with bottleneck, comprises plug hat 2, plug neck 1, there is overlay film 3 on plug neck surface, and plug hat 2 does not have overlay film with the plug hat 2 of plug neck 1 junction with the bottleneck sealing surface.The deficiencies in the prior art part is: only on plug neck surface overlay film is arranged, come though can completely cut off elastomeric material and the medicine in the container of plug neck portion, but because overlay film smooth surface, little with the frictional force of container bottle wall, medicine still might be by the slit of plug neck surface with the bottle wall in the transportation carrying, enter down bottleneck and fall foot, touch the elastomeric material that plug hat and bottleneck sealing surface do not have overlay film.The composition of rubber stopper includes rubber, vulcanizing agent, vulcanization accelerator, filler, plasticizer, protein molecule etc.When plug does not have overlay film part with medicinal liquid, when medicine contacts, thereby influence drug quality, safety, the crisis health.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of improved overlay film plug is provided.
The technical solution of the utility model is as follows: a kind of overlay film plug, comprise plug hat, plug neck, and there is overlay film on described plug neck surface, and described plug hat also has overlay film with the plug hat of plug neck junction with the bottleneck sealing surface.
Described plug hat and bottleneck sealing surface overlay film surpass bottleneck and fall foot, and described plug neck is tapered.
The beneficial effect that this utility model compared with prior art has is: because the plug hat also has overlay film with the plug hat of filling in the neck junction with the bottleneck sealing surface, the feasible plug plug that may come in contact with medicinal liquid, medicine is preced with elastomeric material and medicinal liquid, the medicine of sealing surface and is also isolated fully, avoid the generation of phenomenon that mixes, thereby guaranteed drug quality and health; Simultaneously since the zone of plug hat and bottleneck sealing surface overlay film only in its junction with the plug neck, most of zone that plug hat sealing surface contacts with container finish does not have overlay film, can still guarantee the sealing of plug and container finish.
Description of drawings:
Fig. 1 cooperates sketch map for existing plug with bottleneck;
Fig. 2 is this utility model structural representation;
Fig. 3 is that this utility model cooperates sketch map with bottleneck.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments this utility model is described in detail.
Embodiment 1: as shown in Figure 2, a kind of overlay film plug, comprise plug hat 2, plug neck 1, overlay film 3 covers the plug hat 2 and bottleneck sealing surface of described plug neck 1 surface and described plug hat 2 and plug neck 1 junction, and described plug hat 2 and bottleneck sealing surface overlay film surpass bottleneck and fall foot 4.Described plug neck 1 is tapered, makes plug neck 1 tightr with contacting of bottleneck, further reduces the probability that medicinal liquid enters bottleneck chamfering 4 zones.
In addition to the implementation, this utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of this utility model requirement.
Claims (3)
1. an overlay film plug comprises plug hat, plug neck, and there is overlay film on described plug neck surface, it is characterized in that the described plug hat and the plug hat of plug neck junction also have overlay film with the bottleneck sealing surface.
2. a kind of overlay film plug according to claim 1 is characterized in that described plug hat and bottleneck sealing surface overlay film surpass bottleneck and fall foot.
