Abstract
The utility model relates to a novel halogenated butyl rubber plug for liniment, which comprises a crown part and a neck part abutting against the inner wall of a bottle mouth; a through hole for air exhaust is obliquely downwards arranged along the outer wall of the neck part towards the bottom surface of the neck part; a hemispherical convex block which is hermetically abutted against the opening at one end of the through hole is convexly arranged on the inner wall of the bottle opening; through the neck at the plug seted up slant decurrent through-hole, be provided with the lug that seals the counterbalance with through-hole one end on the bottleneck inner wall and improved the sealing performance of plug and bottle.
Description
Technical Field
The utility model relates to a rubber plug, in particular to a novel halogenated butyl rubber plug for liniment
Background
When the rubber plug is covered on the bottle mouth, gas exists in the bottle, which can oxidize the liniment and the like, thereby polluting the reagent; the conventional method is that a through hole is arranged at the neck part of a rubber plug, and gas in a bottle body is discharged through the through hole;
when the through hole on the outer wall of the neck part is close to the bottle mouth, air can enter from one end of the through hole, and therefore the sealing effect cannot be achieved.
In conclusion, how to improve the sealing performance of the rubber plug becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to improve the sealing performance of the rubber plug;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a novel halogenated butyl rubber plug for liniment, which comprises a crown part and a neck part which is propped against the inner wall of a bottle mouth; a through hole for air exhaust is obliquely downwards arranged along the outer wall of the neck part towards the bottom surface of the neck part; a hemispherical convex block which is hermetically abutted against the opening at one end of the through hole is convexly arranged on the inner wall of the bottle opening;
that is to say, set up the lug at bottleneck outer wall corresponding position, expose when neck through-hole one end, after the air in the extraction bottle, push down the plug, the one end of through-hole offsets with the lug of bottleneck inner wall, further prevents the exchange of air and external in the bottle, has improved the leakproofness of plug.
Because the bottleneck is of a circular ring type, in order to accurately abut and seal the lug and one end of the through hole, the utility model adopts the structure that the outer wall of the neck is vertically provided with a limiting groove, one end of the limiting groove is positioned below the lug, and the other end of the limiting groove is flush with the bottom surface of the neck;
when the rubber plug is pressed downwards, the limiting groove is firstly matched with the lug, the lug plays a limiting role at the moment, the rotation of the rubber plug is limited, the rubber plug gradually moves downwards, the jumping of the rubber plug is sensed through touch, and the lug finally abuts against one end of the through hole to be sealed at the moment.
The utility model has the advantages that: the utility model relates to a liniment is with novel halogenated butyl rubber buffer, through having seted up slant decurrent through-hole at the neck of plug, be provided with on the bottleneck inner wall with the sealed lug that offsets of through-hole one end improved the sealing performance of plug and bottle.
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-crown part, 2-bottleneck, 3-neck part, 4-through hole, 5-lug and 6-limiting groove.
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 figure 1, the utility model relates to a novel halogenated butyl rubber plug for liniment, which comprises a crown part 1 and a neck part 3 which is propped against the inner wall of a bottle mouth 2; a through hole 4 for air extraction is obliquely and downwards arranged along the outer wall of the neck 3 to the bottom surface of the neck 3; a hemispherical convex block 5 which is sealed and abutted with an opening at one end of the through hole 4 is convexly arranged on the inner wall of the bottle mouth 2;
that is to say, set up the lug at bottleneck outer wall corresponding position, expose when neck through-hole one end, after the air in the extraction bottle, push down the plug, the one end of through-hole offsets with the lug of bottleneck inner wall, further prevents the exchange of air and external in the bottle, has improved the leakproofness of plug.
As shown in fig. 1, since the bottle mouth is circular, in order to accurately seal the lug against one end of the through hole, the utility model adopts the structure that a limiting groove 6 is vertically arranged on the outer wall of the neck 3, one end of the limiting groove 6 is positioned below the lug 5, and the other end of the limiting groove 6 is flush with the bottom surface of the neck 3;
when the rubber plug is pressed downwards, the limiting groove is firstly matched with the lug, the lug plays a limiting role at the moment, the rotation of the rubber plug is limited, the jumping of the rubber plug is sensed through touch in the process that the rubber plug gradually moves downwards, and the lug finally abuts against one end of the through hole for sealing;
the other end of the limiting groove is flush with the bottom surface of the neck, so that the limiting groove of the rubber plug can be inserted into the bottleneck with the lug conveniently.
The utility model relates to a liniment is with novel halogenated butyl rubber buffer, through having seted up slant decurrent through-hole at the neck of plug, be provided with on the bottleneck inner wall with the sealed lug that offsets of through-hole one end improved the sealing performance of plug and bottle.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
