Description

Sealing rubber and plastic bottle stopper with inner plug type single-piece cover

Technical Field

The invention relates to the technical field of medical sealing, in particular to a sealing rubber and plastic bottle stopper with an inner plug type single-piece cover.

Background

In consideration of the problem of sealing performance, the current bottle stopper usually adopts a single elastic material, such as a rubber stopper, a cork stopper and the like, while in a bottle package with high sealing requirements, the stopper mouth (the part of the finger sleeve inserted into the bottle mouth) of the bottle stopper is usually required to be longer, so that the friction force between the stopper mouth and the bottle mouth is increased to ensure the sealing performance, and therefore, the bottle stopper needs to be opened by means of an additional opening object when being opened. Even if the stopper has a cap (a portion exposed to the mouth of the bottle), since the cap made of an elastic material is soft, the holding force of the cap by hand directly is not so large, and therefore, it is difficult to pull out the stopper, and in addition, the cap made of such an elastic material is exposed to the outside, and aging is caused for a long time, thereby affecting the operation. Furthermore, caps made of elastomeric material are suitable for single use only, and are easily broken once unsealed, and are mostly no longer sealed.

To this end we propose a sealing rubber stopper with an internal single-piece cap to solve the above mentioned problems.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a sealed rubber and plastic bottle plug of interior stopper formula single cover, includes bottleneck 1 and

rubber buffer

2, 1 inner chamber of rubber buffer 2 activity grafting bottleneck, rubber buffer 2 outer lane bottom rigid

coupling sealing washer

3, 3 movable contact bottleneck 1 inner chambers of sealing washer, 2 top rigid couplings of

rubber buffer boss

4, 1 mouth edges of boss 4 bottom movable contact bottleneck, 2 inner chambers of rubber buffer are equipped with

internal thread

5, 5 threaded connection expanding structure 6 of internal thread. When the expansion structure 6 is screwed up in the inner cavity of the rubber plug 2, the expansion column 60 of the expansion structure 6 can expand the side wall of the rubber plug 2 and the sealing ring 3 and can plug the inner cavity of the bottle mouth 1, thereby sealing the bottle mouth 1.

The bottom of the expansion structure 6 is provided with an expansion column 60, the periphery of the expansion column 6 is provided with an external thread 61, the external thread 61 is in threaded connection with the internal thread 5, the top of the expansion column 60 is fixedly connected with a sealing table 62, the top of the sealing table 62 is fixedly connected with a chuck 63, the top of the chuck 63 is hinged with a force applying rod 64, and the tail end of the force applying rod 64 is fixedly connected with an anti-slip head 65. Under the action of the internal thread 5 and the external thread 61, the expanding column 60 of the expanding structure 6 can be screwed into the inner cavity of the rubber plug 2 by rotating the force applying rod 64.

The top of the clamping head 63 is fixedly connected with a shaft core 66, and the shaft core 66 penetrates through and is rotatably connected with a force application rod 64.

The bottom edge of the boss 4 is fixedly connected with the bottleneck sleeve 40, and the bottleneck sleeve 40 is movably sleeved outside the bottleneck 1, so that the bottleneck sleeve 40 and the rubber plug 2 can be conveniently held.

The surfaces of the rubber plug 2, the sealing ring 3 and the bottleneck sleeve 40 are all provided with concave-convex anti-skid tissues 8.

A soft belt 7 is fixedly connected between the boss 4 and the expansion structure 6, so that the boss and the expansion structure are prevented from being lost after being separated.

The rubber plug 2 is in a round table structure with a small upper part and a large lower part, and the expansion column 60 is favorable for expanding the side wall of the rubber plug 2 and the sealing ring 3.

The working principle is as follows: when the invention is used, the rubber plug 2 is plugged into the inner cavity of the bottle mouth 1, and the rubber plug 2 is pressed and held tightly at the same time, so that the mouth edge of the bottle mouth 1 is tightly sleeved by the bottle mouth sleeve 40; in screwing expansion structure 6 into the inner chamber of rubber buffer 2, wherein under the effect of internal thread 5 and external screw thread 61, rotate the plus force pole 64 and can screw expansion post 60 of expansion structure 6 into the inner chamber of rubber buffer 2, at the in-process of constantly screwing up of expansion post 60, expansion post 60 can expand rubber buffer 2's lateral wall and sealing washer 3 to stopper 1 inner chamber, realize sealed bottleneck 1 from this. When the rubber plug 2 needs to be taken out, the expanding column 60 can be separated from the inner cavity of the rubber plug 2 by reversely rotating the force applying rod 64, and then the rubber plug 2 can be taken out.
