Problems solved by technology
Even if the bottle stopper has a cover (referring to the part exposed to the bottle mouth), because the cover made of elastic material is soft, the holding force of the cover directly will not be too large by hand, so pulling out the bottle stopper will In addition, the cover of this elastic material is exposed, and it will cause aging over time, which will affect the operation
Furthermore, the lid made of elastic material is only suitable for one-time use, and it is easily damaged once it is unsealed, and most of them cannot function as a seal again.

The invention discloses a sealing rubber and plastic bottle plug with an inner plug type single-piece cover. The sealing rubber and plastic bottle plug comprises a bottle opening and a rubber plug body, the rubber plug body is movably inserted into an inner cavity of the bottle opening, the bottom of an outer ring of the rubber plug body is fixedly connected with a sealing ring, the sealing ring is movably in contact with the inner cavity of the bottle opening, the top of the rubber plug body is fixedly connected with a boss, the bottom of the boss is movably in contact with the edge of the bottle opening, internal threads are arranged in an inner cavity of the rubber plug body and connected with an expansion structure in a screwed mode. Compared with the prior art, the sealing rubber andplastic bottle plug has the beneficial effects that under the action of the rubber plug body and the expansion structure, the bottle opening can be sealed, repeated dismounting and sealing can be achieved, and practicability is improved; a soft belt is fixedly connected between the boss and the expansion structure, so that the boss and the expansion structure can be prevented from being lost afterseparation; and by means of a stress application rod, tightening and dismounting are more convenient.
Description
technical field [0001] 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 cap. Background technique [0002] Considering the problem of airtightness, the current bottle stopper usually adopts a single elastic material, such as rubber stopper, cork, etc., and in bottle packaging with high sealing requirements, the stopper of the bottle stopper (referring to the part that fits into the mouth of the bottle) ) usually requires longer, so that the friction between the stopper and the bottle mouth increases to ensure the tightness, and this is therefore, when the bottle stopper is opened, it needs to be opened by means of another opener. Even if the bottle stopper has a cover (referring to the part exposed to the bottle mouth), because the cover made of elastic material is soft, the holding force of the cover directly will not be too large by hand, so pulling out the bot...
