Abstract
The utility model discloses a kind of vial bottle cap of internal plug of choosing, and extracts externally threaded external bottle cap including having with the internal plug and top of extracting internal screw thread.Internal screw thread is extracted in the inner surface side wall setting of the internal plug recess；The top depression of the external bottle cap, and centre is provided with and extracts externally threaded cylindrical projection structure.When in use, external bottle cap, overturning are unscrewed, by external bottle cap top center with the extraction internal screw thread for extracting externally threaded cylindrical projection screw-in internal plug, external screw thread is extracted and extracts screw-internal thread fit, jiggle and pull out external bottle cap, internal plug can be extracted.The utility model has the characteristics that structure is simple, easy to use, solves the problems, such as that Inner plug of bottle cover difficulty takes.
Description
Technical field
It is specific to be sealed to be a kind of for vial of choosing the utility model relates to a kind of vial bottle cap of internal plug of choosing
With the bottle cap of internal plug.
Background technique
With the development of science and technology, requirement of the people to substances such as medicaments is also higher and higher, and existing many glass
Bottle all guarantees that the leakproofness of its interior article, this packaging method can be inhaled because of the substance in some bottles using outer cover encapsulation plus internal plug
It receives air moisture in bottle and generates negative pressure in bottle, be difficult to take out so as to cause the internal plug of vial, it is time-consuming and laborious.It is more existing
Internal plug extractor is not only cumbersome, but also is repeatedly opened internal plug, certain damage can be generated to internal plug, after not can guarantee use
Leakproofness, be easy to lose sealing effect, make the substance dampness or rotten of sealing.Sealing for drug, serious go bad can
It can lead to user's life danger or experiment accident.
Utility model content
The utility model provides a kind of vial bottle cap of internal plug of choosing, so that Inner plug of bottle cover is convenient to remove, it is time saving and energy saving,
It can keep the integrality of internal plug, operator's more convenient operation.
The technical solution adopted in the utility model is: a kind of vial bottle cap for internal plug of choosing, including with spiral shell in extracting
The internal plug of line and top are with the externally threaded external bottle cap of extraction, wherein the side wall of the recess inner surface of the internal plug is arranged
There is extraction internal screw thread；The top depression of the external bottle cap, centre, which are provided with, extracts externally threaded cylindrical projection structure.
Use process involved in the utility model is: when needing to open flask for medicinal preparations, opening external bottle cap, overturns outer blank
Lid matches inside and outside screw thread of extracting at the top of external bottle cap with the extraction internal screw thread for extracting external screw thread cylinder boss screw-in internal plug
It closes, shakes gently external bottle cap and extract outward, thus internal plug of successfully choosing.
Preferably, the side wall of the Inner plug of bottle cover recess inner surface is provided with extraction internal screw thread.
Preferably, in the extraction external screw thread in the cylindrical projection structure of the external bottle cap top center and internal plug recess
The extraction internal screw thread of the side wall on surface is mutually matched internal and external threads structure.
Preferably, the raised brim effect at the external bottle cap top edge is protection among it with extraction external screw thread
Cylinder boss.
Preferably, the inner wall of the peripheral edge portion at the top of the external bottle cap is provided with constant slope and fillet, it is ensured that adds
The convenience of work and dedusting, optionally, gradient are 5 ° ~ 8 °, radius of corner 1mm-3mm.
Detailed description of the invention
Fig. 1 is assembling schematic diagram of the utility model on flask for medicinal preparations.
Fig. 2 is that the utility model is chosen the bottle cap schematic diagram of internal plug.
Fig. 3 is the utility model Inner plug of bottle cover schematic diagram.
Fig. 4 be the utility model choose internal plug bottle cap using schematic diagram.
In figure: 1, external bottle cap；101, external screw thread is extracted；2, internal plug；201, internal screw thread is extracted；3, vial.
Specific embodiment
The implementation of the utility model is described in further detail below with reference to figure.
A kind of vial bottle cap for internal plug of choosing, including with the internal plug 2 for extracting internal screw thread 201 and with extraction external screw thread
101 external bottle cap 1, wherein the side wall of the recess inner surface of the internal plug 2, which is provided with, extracts internal screw thread 201；Described is outer
The top depression of bottle cap 1, the intermediate cylindrical projection structure for being provided with extraction external screw thread 101.
The inner surface of 2 recess of Inner plug of bottle cover, which is provided with, extracts internal screw thread 201, and thickness is not less than common internal plug
Thickness, internal plug selected by present case is with a thickness of 3mm.
Increase raised brim at 1 top edge of external bottle cap with convex with the cylinder for extracting external screw thread 101 among it
Platform.
The side of the extraction external screw thread 101 and 2 recess inner surface of internal plug of the cylinder boss of 1 top center of external bottle cap
201 structure of extraction internal screw thread of wall cooperates.
The inner wall of the peripheral edge portion at 1 top of external bottle cap is provided with constant slope and fillet, it is ensured that processes and removes
The convenience of dirt, optionally, gradient are 5 ° ~ 8 °, radius of corner 1mm-3mm, and gradient used by present case is 5 °, fillet
Radius is 2mm.
