Abstract

The present invention is a metal fixing ring structure of a medicine bottle. The fixing ring is used to maintain the sealing state of the stopper of the bottle mouth of the injection medicine bottle. The fixing ring is mainly composed of a metal material. The inner edge forms an inner surface, the side wall is divided into a first end and a second end in the height direction, the first end has an upper cover portion extending to the center of the side wall, and the upper cover portion has an opening , which is characterized in that: the inner surface of the side wall has at least one line extending between the first end and the second end direction, through the setting of the line, when the fixing ring is squeezed to cover the plug on the When the mouth of the medicine bottle is used, the wrinkle effect of the side wall and the line pattern can increase the friction force generated by the fixed ring on the application surface of the medicine bottle, thereby preventing slippage, so as to ensure the medicine bottle. After the mouth is sealed, the problem of poor sealing effect occurs due to the loosening or rotation of the fixing ring.

Description

Metal fixing ring structure of medicine bottle

This creation relates to a metal fixing ring for injection medicine bottles, and more specifically, it is a metal fixing ring structure used to maintain the plugged state of the bottle mouth stopper of the injection medicine bottle.

Please refer to FIG. 1 , which is a conventional capping structure for an injection medicine bottle 10 . The capping structure is usually a two-piece assembly, which includes a plug 12 and a fixing ring 14 . The stopper 12 is made of vulcanized rubber or similar elastic material, the stopper 12 is inserted into the mouth 102 of the medicament bottle 10 and is configured to achieve a circumferential seal of the mouth 102 .

The fixing ring 14 is implemented to constitute the restriction between the stopper 12 and the bottle mouth 102 to prevent the stopper 12 from loosening. Usually, the upper end of the fixing ring 14 has an opening 142, so that a part of the stopper 12 can be blocked. exposed to provide the insertion of the needle, thereby allowing the drug to be withdrawn; traditionally, the retaining ring is made of metal material, which is mainly aluminum, the outer edge of the bottle mouth 102 of the medicine bottle 10 is designed with a lip 104, the retaining ring 14 After being inserted between the stopper 12 and the lip 104 of the vial 10, the lower end of the fixing ring is bent inwardly to cover the lip 104 by means of metal crimping technology, so that the fixing ring 14 can ensure The closed state of the stopper 12, the crimped metal retaining ring 14 additionally provides a mechanism that can be used to ensure that the medicament bottle is not at risk of being opened or damaged after filling or sterilization.

In addition, the fixing ring 14 further includes a cap 16 . The bottom of the cap 16 has several hook ears 162 arranged around the edge of the opening 142 . The cap 16 is engaged with the opening by the hook ears 162 . The hole 142 is fixed and sealed on the upper surface of the fixing ring 14 to cover the opening 142 , so that the plug 12 exposed by the opening 142 can be prevented from external contamination.

Although the above-mentioned conventional aluminum fixing ring can achieve the plugging state of supporting the stopper, after the capping structure seals the bottle, the inner wall of the fixing ring is smooth, so that the fixing ring seals the stopper to the medicine bottle. After the mouth, the fixing ring may be loose or rotated, which may affect the user's perception and misunderstand that the quality of the contents in the bottle is deteriorated, or may affect the sealing performance of the stopper.

In this way, in view of the shortcomings of the conventional capping structure of the injection medicine bottle, how to provide a fixing ring structure with a better fixing implementation will be the problem to be solved by the present invention.

Therefore, in order to increase the sealing stability of the medicine bottle, the author proposes a metal fixing ring structure for the medicine bottle. The fixing ring has a surrounding side wall, the inner edge of the side wall constitutes an inner surface, the side wall is divided into a first end and a second end according to its height direction, and the inner surface of the side wall has at least one extending in the first end. The line between the direction of the end and the second end.

In a possible embodiment, the lines are distributed between the inner surfaces of the first end and the second end.

In a possible embodiment, the lines are distributed on the inner surface of the second end.

Preferably, the lines are groove-shaped scribe lines that penetrate deep into the inner surface of the sidewall.

Preferably, the line is a rib-shaped line protruding from the inner surface of the side wall.

Preferably, the line width of the lines is between 0.1 and 2.0 mm.

In a feasible embodiment, the thread lines are arranged in a clockwise or counterclockwise direction in a spiral extending direction between the first end and the second end.

In addition, the first end of the side wall has an upper cover portion extending toward the center of the side wall, and the upper cover portion has an opening.

Other objects, advantages and features of the present creation will be understood from the following detailed description of the preferred embodiments and with reference to the accompanying drawings.

The preferred content of the present invention will now be described below with reference to the accompanying drawings, which are intended to be examples only and not intended to be limiting. It should be understood that the phraseology and terminology employed herein are for the purpose of description, and should not be considered restrictive.

Please refer to FIG. 2, FIG. 3 and FIG. 4, the metal fixing ring 20 of the pharmaceutical bottle of the present invention has a side wall 22 arranged in a ring, the inner edge of the side wall 22 forms an inner surface 222, and the side wall 22 is in the height direction area The partition has a first end 24 and a second end 26, the first end 24 has a side wall facing the 22 an upper cover portion 28 extending from the center, the upper cover portion 28 has an opening 21 .

The main feature of the present invention is that the inner surface 222 of the side wall 22 has at least one line 23 extending between the first end 24 and the second end 26. In the figure, the line 23 is distributed and implemented on the first end 23. Between the end 24 and the inner surface 222 of the second end 26; in one embodiment, the line 23 is a groove-shaped scribe line penetrating the inner surface 222 of the side wall 22, preferably, the line width of the line 23 is 0.1~ 2.0mm, and the lines 23 are at least two lines 23 equiangularly arranged on the inner surface 222 of the side wall 22, in the figure, six line lines 23 are arranged in equiangular rings inside the side wall 22 Surface 222.

The second end 26 of the fixing ring 20 will be bent to cover and seal the lip of the opposite medicine bottle mouth under the implementation of the capping machine. The wrinkle-pressing effect can increase its frictional force to produce an anti-slip effect, so that the fixed ring 20 is not easily loosened or rotated in the implementation state, thereby ensuring the quality and safety of the contents of the medicine bottle.

In another possible embodiment, the line 23 is a rib-shaped line protruding from the inner surface 222 of the side wall 22 , as shown in FIG. 5 . In addition, the lines 23 may also extend along the height direction of the side wall 22 and are only arranged on the inner surface 222 of the second end 26 , as shown in FIG. 6 . Furthermore, the lines 23 can also be spirally extended in a clockwise or counterclockwise direction according to the height direction of the side wall 22 , as shown in FIG. 7 .
