Description
Technical field
The utility model belongs to medicine instrument field, and in particular to a kind of novel potent sealing butyl rubber stoppers.
Background technology
Currently, the encapsulation of bottled intravenous injection drug is generally sealed up for safekeeping using butyl rubber bung, because of butyl rubber itself gas
Close property is good, substantially increases the package quality of drug.The cooperation of existing butyl rubber bung and bottleneck is interference fit, interference volume
Generally 0.5mm-1.5mm, once being more than the interference volume of 1.5mm, butyl rubber bung can not be just inserted into bottle.But due to butyl rubber
There are the properties of creep for glue itself, and in the shelf life of entire drug, this interference seal of rubber plug and bottleneck can weaken, and cause
There are spoilage problems in shelf life in drug.
Utility model content
The utility model is interference fit for the cooperation for solving existing butyl rubber bung and bottleneck, if interference volume is excessive
Butyl rubber bung can not be just inserted into bottle, if interference volume is too small, since there are the properties of creep for butyl rubber itself, in entire medicine
In the shelf life of product, this interference seal of rubber plug and bottleneck can weaken, and cause drug to occur spoilage problems in shelf life, carry
Butyl rubber stoppers are sealed for a kind of novel potent.
To achieve the above object, the utility model uses following technical proposals:A kind of novel potent sealing butyl rubber glue
Plug, it includes plug sleeve and cock body, and the plug sleeve chamber on connection plug sleeve top and bottom end inside plug sleeve is offered in the plug sleeve,
It is opened from the top to the bottom spiral groove on the inner wall of the plug sleeve chamber;Plug sleeve is provided with plug sleeve ring on the top of the plug sleeve
Portion, the plug sleeve ring portion form bottleneck by the top links of plug sleeve transition part and plug sleeve between the plug sleeve ring portion and plug sleeve
Card slot;
The cock body includes sequentially connected cock body handle from top to bottom, cock body limit chuck and cock body column, in the cock body
The spiral salient suitable for being coordinated with plug sleeve intracavitary spiral groove is from top to bottom consolidated on column.
Preferably, it is consolidated with pothook on the side wall in plug sleeve ring portion bottom end towards plug sleeve.
Preferably, the plug sleeve, plug sleeve transition part and plug sleeve ring portion are made into integration;The cock body handle, cock body limit chuck
It is made into integration with cock body column.
The utility model has the beneficial effects that:
When the utility model is packaged operation, plug sleeve is filled in bottleneck, by the plug sleeve ring portion cutting ferrule of plug sleeve top end
On the outer wall on bottleneck top so that bottleneck card slot is fixed in the top edge of bottleneck, is completed plug sleeve and is assembled with bottleneck, is passed through
Bottleneck card slot is arranged to fix in bottle mouth position so that the top of bottleneck is completely wrapped, even if plug sleeve occurs to can guarantee if creep
Leakproofness between plug sleeve and bottleneck.
After plug sleeve is assembled with bottleneck, the assembly of cock body is carried out, cock body column is screwed in plug sleeve by specially hand-held cock body handle
Plug sleeve intracavitary, and make cock body column on spiral salient screw in spiral groove in coordinated with spiral groove.Spiral salient
Coordinate with this helicitic texture of spiral groove, even if in the case where creep occurs for butyl material, can also ensure to fill in
Leakproofness between set and cock body.
Description of the drawings
Fig. 1 is the internal structure schematic diagram of plug sleeve;
Fig. 2 is the overall structure diagram of cock body;
Fig. 3 is the assembling structure schematic diagram of plug sleeve and cock body;
In figure:Plug sleeve 1, plug sleeve chamber 1a, plug sleeve ring portion 1b, pothook 11b, plug sleeve transition part 1c, card slot 1d, spiral groove
1e, cock body 2, cock body handle 2a, cock body limit chuck 2b, cock body column 2c, spiral salient 2e, bottleneck 3.
Specific implementation mode
What needs to be explained here is that the noun of locality it is left and right, it is upper and lower be to be defined on the basis of view shown in FIG. 1
, it should be understood that the use of the noun of locality should not limit the requested protection domain of the application.
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, a kind of novel potent seals butyl rubber stoppers, it includes plug sleeve 1 and cock body 2, the plug
The plug sleeve chamber 1a through 1 inside connection 1 top of plug sleeve and bottom end of plug sleeve is offered in set 1, on the inner wall of the plug sleeve chamber 1a
It has been opened from the top to the bottom spiral groove 1e;Plug sleeve 1 is provided with plug sleeve ring portion 1b, the plug sleeve on the top of the plug sleeve 1
Ring portion 1b forms bottleneck card slot by the top links of plug sleeve transition part 1c and plug sleeve 1 between the plug sleeve ring portion 1b and plug sleeve 1
1d;
The cock body 2 limits chuck 2b and cock body column 2c including sequentially connected cock body handle 2a from top to bottom, cock body, in institute
State the spiral salient 2e being from top to bottom consolidated on cock body column 2c suitable for being coordinated with plug sleeve chamber 1a inside spin grooves 1e.
A kind of novel potent sealing butyl rubber stoppers of the utility model first fill in plug sleeve 1 when being packaged operation
Into in bottleneck 3, the plug sleeve ring portion 1b of 1 top end of plug sleeve is fastened on the outer wall on 3 top of bottleneck so that bottleneck card slot 1d is fixed
