Background

At present, a screw bottle is a common glass instrument in a laboratory and is mainly used for storing liquid medicine, reagents, samples and the like. Most of screw bottles in the related art adopt a mode of padding a silica gel pad on the inner wall of a bottle cap to ensure the sealing property of the screw bottle after the bottle body is covered.

To the correlation technique among the above-mentioned, the inventor thinks that only adopt the silica gel pad dish to seal the screw bottle, if the experimenter when the closing cap screw bottle, do not revolve the bottle lid to the tightest make silica gel pad dish and bottleneck hug closely, there is the gap still between that silica gel pad dish and the bottleneck to cause volatilizing of medicament easily or easily leading to external bacterium to get into in the bottle, and then cause liquid medicine chemical property unstability in the bottle.

Disclosure of Invention

In order to improve because sealed poor medicine liquid chemical property unstable problem in leading to the bottle, this application provides the screw-top bottle of the liquid medicine chemical property of being convenient for stable.

The application provides a screw bottle convenient to liquid medicine chemical property is stable adopts following technical scheme:

a screw bottle convenient for chemical property stabilization of liquid medicine comprises a bottle body and a bottle cap, wherein the bottle body is provided with a bottle opening, the outer wall of the bottle opening is provided with external threads, the bottle cap is in threaded connection with the bottle opening, a pad disc is embedded in the inner top wall of the bottle cap, and the pad disc is pressed against one end, far away from the bottle body, of the bottle opening; one side of the pad disc, which faces the bottle mouth, is connected with an inner plug body, and the inner plug body extends into the bottle mouth and is abutted against the inner wall of the bottle mouth; the inner wall of the bottle mouth is connected with an air bag layer, the air bag layer is hollow, and a filling medium is filled in the air bag layer;

the diameter of the end, far away from the saucer, of the inner plug body is gradually reduced, and the inner diameter of the end, far away from the saucer, of the air bag layer is gradually reduced.

Through adopting above-mentioned technical scheme, when covering the bottle lid, interior cock body gets into in the bottleneck, makes interior cock body stretch into in the bottleneck gradually and shutoff bottleneck along with the rotation of bottle lid. Compared with the prior art in which only one pad disc is arranged, even if the bottle cap is not screwed to enable the pad disc to abut against the bottle opening, the inner plug body can also play a role in effectively blocking the bottle opening, so that volatilization of a medicament or external bacteria entering the bottle is reduced, and chemical performance of liquid medicine in the bottle can be stable. And the scrappage of the medicament can be reduced, thereby achieving the effects of energy conservation and environmental protection.

When the inner plug body is not plugged in, the filling medium in the air bag layer is in a free state in the air bag layer. The inner plug body is wide at the upper part and narrow at the lower part, so that when the inner plug body is plugged in, the inner plug body cannot extrude the air bag layer at the beginning, the inner plug body gradually extrudes the air bag layer along with the increasing diameter of the inner plug body plugged in the bottleneck, and the filling medium at the upper part of the air bag layer is gradually extruded towards the lower part, so that the side wall at the bottom end of the inner plug body is tightly attached to the inner wall at the bottom end of the air bag layer; when the inner plug body completely enters the bottleneck, the outer wall of the upper part of the inner plug body is tightly attached to the inner wall of the upper part of the air bag layer, and the effect of effectively sealing the inner wall of the bottleneck is achieved. The pressing of cooperation deep bead and bottleneck plays double seal's effect, and the chemical stability of the liquid medicine in the screw bottle is better.

Optionally, one end of the bottle mouth facing the pad disc is connected with an air bag ring, the air bag ring is hollow, and a filling medium is filled in the air bag ring; the air bag ring is abutted against the cushion disc.

Through adopting above-mentioned technical scheme, the bottleneck supports with the rim plate through gasbag circle and presses, thereby gasbag circle violently more receives the pressure deformation to support with the rim plate and press, and then plays the effect of sealed bottleneck.

Optionally, the saucer is located the stopper body periphery and installs the bellying, the bellying supports one side that the gasbag circle kept away from the stopper body in, just the orthographic projection of bellying is located the bottleneck.

Through adopting above-mentioned technical scheme, under the extrusion of bellying, can be so that the gasbag layer towards the contained angle department deformation that internal plug body and saucer formed to effectively seal the bottleneck.

Optionally, a notch is formed in the outer wall of the mouth portion of the bottle, and the protruding portion is matched with the notch through the airbag ring.

Through adopting above-mentioned technical scheme, along with the bellying sees through gasbag circle and breach agrees with for gasbag layer can directional deformation and can closely support with the outer wall on saucer and interior cock body top and press, promotes the sealed effect of screw bottle.

Optionally, the airbag ring is communicated with the airbag layer.

Through adopting above-mentioned technical scheme, gasbag circle and gasbag layer communicate, when gasbag circle deformation towards interior cock body one side, can squeeze into the gasbag in situ with some filling medium to make the connection of gasbag layer and interior cock body more inseparable, thereby play better sealed effect.

Optionally, a plurality of vertically arranged communicating pipes are arranged on the air bag ring, and the communicating pipes are communicated with the air bag ring; the top wall of the bottle cap is provided with a mounting hole, a rotary cover plate is mounted at the mounting hole, and the rotary cover plate is used for plugging the mounting hole and is rotationally connected with the bottle cap; the cushion disc is arranged on the rotary cover plate, an inserting hole is formed in the position of the rotary cover plate corresponding to the communicating pipe, and the communicating pipe penetrates through the cushion disc and extends into the inserting hole; a vertically arranged corrugated pipe is installed on one side, away from the pad, of the rotary cover plate, two ends of the corrugated pipe are plugged by plates, a through hole is formed in one end, facing the bottle cap, of the corrugated pipe, corresponding to the communicating pipe, and the communicating pipe is communicated with the corrugated pipe; and a locking assembly for compressing the corrugated pipe is arranged on the bottle cap.

By adopting the technical scheme, the screw bottle in the related technology needs the bottle cap to be in threaded connection with the bottle body, the inner plug body extends into the bottle mouth and is necessarily in relative rotation friction with the inner wall of the bottle mouth, and the difficulty of the inner plug body entering the bottle mouth is large under the abutting pressure of the air bag layer. This application technical scheme is when rotatory bottle lid, because the setting of communicating pipe, gasbag layer and gasbag circle leak gas, so in the cock body can stretch into the bottleneck in the condition of contactless gasbag layer, reduce the degree of difficulty of screwing of bottle lid. The cover plate is rotated to enable the bottle cap to be opened or locked in a spiral mode, the communicating pipe is not driven to be staggered, and the communicating pipe can gradually stretch into the inserting hole. When the bottle lid is screwed, press and fixed bellows through the locking subassembly, the bellows makes the gas in the bellows pass through communicating pipe and gets into in gasbag circle and the gasbag layer owing to the compression to make gasbag layer and gasbag circle bloated and sealed the bottleneck.

When the bottle cap needs to be opened, the locking assembly also only needs to be opened, the corrugated pipe rebounds and resets to absorb gas in the air bag layer and the air bag ring, and the air bag layer and the air bag ring are flat and dry, so that the bottle cap can be opened easily.
