Abstract
The utility model discloses a seamless rubber plug with a laminated film. The seamless rubber plug comprises a plug crown part and a plug neck part, wherein a boss is arranged below the plug neck part, the laminated film is arranged on the outer surface of the boss, and no gap exists between the laminated film and the plug neck part. After the rubber plug and a medicinal bottle are combined, the plug neck part and a bottle mouth are closely attached to realize favorable sealing property; the laminated film can be used for effectively preventing chemical components in the rubber plug from releasing into the bottle to influence medicaments.
Description
Technical field
This utility model relates to a kind of medical coated rubber plug.
Background technology
The medical rubber plug that infusion solutions, antibiotic or lyophilized formulations use all exists plug to pollute the problems such as medicinal liquid or medicated powder, causes product bad, and the pharmaceutical factory is sustained a great loss.Because rubber stopper contains the compositions such as vulcanizing agent, promoter, plasticizer, through after a while or through operations such as autoclaving or UV irradiations, its inside can discharge above-mentioned substance, and affect medicament, in order to prevent above-mentioned variety of problems, manufacturer has released coated rubber plug, namely at the surface coating of plug.
But, present coated rubber plug is owing to the reason of manufacturing process, or all be compounded with overlay film at whole lower surface, namely not only enter the bottleneck portion overlay film at plug, and also be provided with overlay film in the bottom surface of plug bizet, cause coated rubber plug and vial or plastic bottle when combination, cause easily the poor sealing of plug bizet bottom surface and bottleneck end face, make air enter bottle interior or when autoclaving steam enter a bottle internal contamination medicine; Or at the lower surface overlay film of filling in cervical region, and the plug cervical region does not fit tightly with the inner surface of bottleneck, sealing on medicine bottle has certain impact, and leave a little gap between the lower surface of the part of overlay film and plug bizet, when carrying out autoclaving or UV irradiation and wait to operate, can discharge the material that some affect medicament.
The utility model content
This utility model purpose is: a kind of seamless coated rubber plug is provided, plug cervical region and the bottleneck inner surface of this plug fit tightly, only at the do not fit part overlay film of bottleneck of plug cervical region head, can stop chemical constituent in the plug to discharge in the bottle and affect medicine, can make again the good seal of plug and bottleneck, stop air, steam to enter in the bottle.
The technical solution of the utility model is: a kind of seamless coated rubber plug, and comprise the plug bizet and be arranged on the plug cervical region of plug bizet below, the below of plug cervical region is provided with down a boss, and the outer surface of described boss is provided with overlay film.
Preferably, the overlay film of boss outer surface is seamless with the plug cervical region.
The utility model has the advantages that:
1. plug of the present utility model is provided with overlay film at the boss outer surface, and after the combination of coated rubber plug and medicinal bottle, can stop chemical constituent in the plug to discharge in the bottle affects medicine.
. plug of the present utility model is provided with boss at the plug cervical region, the overlay film of boss outer surface and plug cervical region and tight, and after plug and medicinal bottle combination, plug cervical region and bottleneck inner surface fit tightly, and have good sealing, stop outside air to enter in the bottle.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is the sketch map of seamless coated rubber plug of the present utility model.
Wherein: 1. plug bizet 2. is filled in cervical regions 3. boss 4. overlay films.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of seamless coated rubber plug comprises plug bizet 1 and plug cervical region 2, plug cervical region 2 is arranged on the below of plug bizet 1, the below of plug cervical region 2 is provided with down a boss 3, and the outer surface of boss 3 is provided with overlay film 4, and the overlay film 4 of boss 3 outer surfaces is seamless with plug cervical region 2.
Above-mentioned overlay film 4 is the thin film that PE, PP or fluorine cellulosic material are made.
During the combination of seamless coated rubber plug of the present utility model and medicinal bottle, plug cervical region 2 fits tightly with the inner surface of bottleneck, because the cross section of boss 3 is less than the cross section of plug cervical region 2, and the overlay film 4 that boss 3 outer surfaces arrange and plug cervical region 2 and seamless; Overlay film 4 can effectively stop the chemical constituent in the plug to discharge in the bottle and affect medicine; Also seamless between overlay film 4 and the plug cervical region 2, plug has good sealing.
Those skilled in the art will readily understand; the above only is preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
