Abstract
The utility model relates to a sealing member of medical container specifically is a plug for aseptic freeze-dried powder, including plug crown and plug neck, the plug neck is fixed to be installed the lower surface of plug crown, supreme first location body and the second location body of having set gradually are followed along the semicircle week to the lower part side of plug neck the upper portion of second location body is followed plug neck circumferencial direction has evenly seted up the exhaust hole, the fixed cover in upper portion of plug neck is equipped with the sealing ring. The rubber plug for sterile freeze-dried powder provided by the utility model has no split as a whole, and the rubber plug can not be interlaced and held together, thereby being beneficial to the wiring on the machine of a pharmaceutical factory; meanwhile, the air exhaust requirement of the sterile freeze-dried medicinal powder in the freeze-drying sublimation process is completely met, and the freeze-drying curve meets the process requirement of the freeze-dried medicinal powder.
Description
Technical Field
The utility model relates to a sealing piece of a medical container, in particular to a rubber plug for sterile freeze-dried powder.
Background
The halogenated butyl rubber plug for freeze drying for injection has three structures which are universal internationally and domestically, namely one fork, two forks and three forks. The product with the fork structure has low universality, mainly the fork structure is provided with only one exhaust channel, the sublimation rate of the sterile medicinal powder is low in the freeze-drying sublimation process, the freeze-drying time of the Chinese medicinal freeze-dried preparation is long, and the water content of the medicinal powder is not well controlled; the two-fork and three-fork products are varieties with higher market share at present, particularly the three-fork products, and the freeze-drying curve meets the requirements of most sterile freeze-drying powder. However, in the processes of packaging, storing, transporting and using of the two-fork and three-fork products, the defects that the products are easy to deform under pressure and the two rubber plug branching structures are easy to be mutually staggered and clasped together exist, and the two situations can seriously influence the wiring on the product.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the defects that the two-fork freeze-dried powder rubber plug and the three-fork freeze-dried powder rubber plug are easy to deform under pressure in the packaging, storage, transportation and use processes, and the fork-shaped structures are easy to be mutually staggered and clasped together are overcome.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pair of plug for aseptic freeze-dried powder, including plug crown and plug neck, the plug neck is fixed to be installed the lower surface of plug crown, supreme first location body and the second location body of having set gradually are followed along the semicircle week to the lower part side of plug neck the upper portion of the second location body is followed plug neck circumferencial direction has evenly seted up the exhaust hole, the fixed cover in upper portion of plug neck is equipped with the sealing ring.
The side surface of the lower part of the neck of the rubber plug is sequentially provided with a first positioning body and a second positioning body from bottom to top along the half circumference, so that the ascending and descending height of the rubber plug can be positioned; vent holes are uniformly formed in the upper portion of the second positioning body along the circumferential direction of the neck of the rubber plug, the neck of the rubber plug adopts a punching design, the neck of the rubber plug does not need to be forked, the circumferential integrity of the neck of the rubber plug is kept, sublimation and exhaust in the freeze-drying process of sterile medicinal powder are realized, and meanwhile, the defects that products with forked structures are easy to deform and are staggered two by two to form a cluster are avoided; the upper part of the neck of the rubber plug is fixedly sleeved with a sealing ring to play a role in sealing.
Further, first location body and second location body are the sand grip, set the location body into the sand grip, and the area of contact of sand grip and freeze-drying powder bottle internal perisporium is big can fix a position better.
Furthermore, the total of three exhaust holes are arranged at intervals of 120 degrees along the circumferential direction of the neck of the rubber plug, so that the exhaust requirement of the sterile freeze-dried medicinal powder in the freeze-drying sublimation process is completely met, and the freeze-drying curve meets the technological requirement of the freeze-dried medicinal powder.
Furthermore, the vent hole and the rubber plug crown form a 45-degree included angle, so that the mold opening of the vulcanized product is facilitated.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-rubber plug crown part, 2-sealing ring, 3-vent hole, 4-second positioning body, 5-first positioning body and 6-rubber plug neck part.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model provides a pair of plug for aseptic freeze-dried powder, including plug crown 1 and plug neck 6, plug neck 6 is fixed to be installed the lower surface of plug crown 1, supreme first location body 5 and the second location body 4 of having set gradually are down followed to the lower part side of plug neck 6 semicircle the upper portion of second location body 4 is followed 6 circumferencial direction of plug neck has evenly seted up exhaust hole 3, the fixed cover in upper portion of plug neck 6 is equipped with sealing ring 2.
The side surface of the lower part of the rubber plug neck part 6 is sequentially provided with a first positioning body 5 and a second positioning body 4 from bottom to top along the half circumference, so that the ascending and descending height of the rubber plug can be positioned; the upper part of the second positioning body 4 is uniformly provided with the exhaust holes 3 along the circumferential direction of the rubber plug neck 6, the rubber plug neck 6 adopts a punching design, the rubber plug neck 6 does not need to be forked, the circumferential integrity of the rubber plug neck 6 is kept, the sublimation exhaust in the freeze-drying process of the sterile medicinal powder is realized, and meanwhile, the defects that products with forked structures are easy to deform and are staggered and agglomerated in pairs are avoided; the upper part of the rubber plug neck part 6 is fixedly sleeved with a sealing ring 2 to play a role in sealing.
Further, first location body 5 and second location body 4 are the sand grip, set the location body to the sand grip, and the big area of contact of sand grip and freeze-drying powder bottle internal perisporium can fix a position better.
Furthermore, the total number of the exhaust holes 3 is three, and the exhaust holes are arranged at intervals of 120 degrees along the circumferential direction of the neck part 6 of the rubber plug, so that the exhaust requirement of the sterile freeze-dried medicinal powder in the freeze-drying sublimation process is completely met, and the freeze-drying curve meets the process requirement of the freeze-dried medicinal powder.
Furthermore, the vent hole 3 and the rubber plug crown part 1 form an included angle of 45 degrees, so that the mold opening of the vulcanized product is facilitated.
