Description

Technical Field

[0001] The utility model relates to the field of medicine packaging, in particular to a multi-layer sealed anti-permeation medicine bottle structure. Background Art

[0002] A medicine bottle is a container for storing medicine or liquid medicine. Generally, a medicine bottle is divided into a bottle body and a bottle cap. When taking the liquid medicine, the bottle cap is generally opened to directly pour out the liquid medicine in the inner cavity of the bottle, and then the bottle cap is connected to the bottle body.

[0003] However, the prior art has the following defects:

[0004] However, the connection between the existing medicine bottle and the bottle cap is not tight, resulting in a weak seal. During transportation or when the patient is taking the medicine away, the medicine stored inside will seep out from the gap, which will not only cause the loss of the medicine but also soil other items in the bag. After the medicine is poured out, some of it will remain on the top of the bottleneck, slide down the outside of the bottleneck back into the bottle or remain on the outer wall, which is easy to breed bacteria and cause contamination of the medicine when it is used next time. Utility Model Content

[0005] The purpose of the present invention is to provide a multi-layer sealed anti-permeation medicine bottle structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-layer sealed and impermeable medicine bottle structure, comprising a medicine bottle body and a bottle cap, the top of the medicine bottle body being provided with a second bottleneck and a first bottleneck in sequence from the outside to the inside, the inner side of the bottom of the second bottleneck and the outer side of the bottom of the first bottleneck being fixedly connected by a circular ring plate, an aluminum foil sealing cover being tightly bonded to the inner wall of the bottom of the first bottleneck, a rubber stopper being snap-fitted onto the inside of the first bottleneck, a protruding ring plate being fixedly mounted onto the outer side of the bottom of the second bottleneck, a first groove being provided on the top of the protruding ring plate, a bottle cap being threadedly mounted on the outer side of the second bottleneck and the bottom of the bottle cap being snap-fitted onto the inside of the first groove, and a sealing gasket being bonded to the inner wall of the first groove.

[0007] The above-mentioned technical solution is adopted, in which the first bottleneck is used to pour the medicine liquid, the second bottleneck is connected to the bottle cap, and a gap is left between the first bottleneck and the second bottleneck. The medicine liquid remaining at the bottle mouth will flow from the outside of the first bottleneck to the circular plate to avoid flowing back into the bottle and contaminating the medicine liquid. A sealing gasket is provided at the bottom of the bottle cap and the first groove to improve the sealing performance and prevent the medicine liquid from leaking out.

[0008] The bottle cap is divided into an upper part and a lower part. The outer side of the upper part is evenly provided with a plurality of convex strips. The outer side of the lower part is provided with an external thread. The inner wall of the first groove is provided with an internal thread. The lower part of the bottle cap is threadedly connected to the first groove.

[0009] By adopting the above technical solution, the lower part of the bottle cap is threadedly connected to the first groove, the connection is tight, and the convex strip increases the friction force, making it easy to rotate the bottle cap for opening and closing.

[0010] The top of the first bottleneck is provided with an inclined cut so that one side of the first bottleneck is higher than the other side, the height of the second bottleneck is lower than that of the first bottleneck, and the first bottleneck is located inside the second bottleneck and the two are concentrically arranged.

[0011] The above technical solution is adopted, in which the top of the first bottleneck is set at an angle to facilitate pouring of the medicine liquid and prevent the medicine liquid from spilling during the pouring process. The second bottleneck is lower than the first bottleneck, which does not affect the pouring of the medicine liquid from the first bottleneck and can also prevent the medicine liquid on the circular plate from flowing out and seeping out.

[0012] The aluminum foil sealing cover is provided with a circular easy-tear dotted line, and an easy-tear sheet is fixedly installed on one side of the easy-tear dotted line. The inner wall of the top of the bottle cap is bonded with a sealing gasket.

[0013] By adopting the above technical solution, the medicine bottle is sealed with an aluminum foil sealing cover when it is not sold, which not only plays a sealing role but also can prevent the medicine liquid from deteriorating.

[0014] A circular top plate is fixedly installed on the top of the rubber stopper, and the diameter of the circular top plate is larger than the diameter of the top of the rubber stopper. A second groove is provided on the top of the circular top plate, and a rubber disc is fixedly installed in the middle of the inner wall of the bottom of the second groove through a connecting column. A third groove is provided on one side of the two ends of the top of the circular top plate close to the second groove.

[0015] By adopting the above technical solution, both sides of the rubber disc can be lifted from the third groove, and then the rubber plug can be pulled out by pulling it upwards.

[0016] The circular top plate is made of hard rubber material, and the rubber disc is made of soft rubber material, and the top of the rubber disc is higher than the top of the circular top plate.

[0017] The above technical solution is adopted, in which the bottom of the rubber stopper is conical, which is convenient for inserting into the interior of the first bottleneck for sealing, and the rubber disc is higher than the circular top plate for easy lifting.

[0018] A cavity is provided inside the medicine bottle body, an external thread is provided on the outer wall of the second bottleneck, and an internal thread is provided on the inner wall of the bottle cap.

[0019] By adopting the above technical solution, the cavity of the solution is convenient for storing liquid medicine, and the inner side of the bottle cap is tightly connected with the outer side of the second bottleneck through threads.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model is that when the medicine is not sold, the bottle mouth is bonded and sealed by the aluminum foil sealing cover. When the medicine is sold and taken, the aluminum foil sealing cover is torn off, and the rubber plug can be inserted into the first bottleneck to play a sealing role. The bottle cap is threadedly connected to the first groove and a sealing gasket is provided between the two, which can enhance the sealing performance of the medicine bottle and prevent the drug solution from leaking out.
