Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described more clearly and more completely with reference to the drawings in the following embodiments, and it is understood that the described embodiments are only a part of the present invention, rather than all of the present invention, and based on the embodiments, other embodiments obtained by those skilled in the art without inventive exercise are within the protection scope of the present invention.

As shown in fig. 1 to 4, a medical film coated rubber stopper comprises a cover plate part 1, an insertion part 2 and a peripheral part 3, wherein an annular groove 11 is arranged on the cover plate part 1, a liftable pull ring 12 is accommodated in the groove 11, the pull ring 12 is rotatably connected with a connecting seat 13 in the groove 11, a through hole 14 communicated with a hollow inner cavity 31 of the peripheral part 3 is arranged in the groove 11, the through hole 14 is positioned on the side surface of the connecting seat 13 and is covered by the pull ring 12, a tapered valve core 15 in interference fit is inserted into the through hole 14, the valve core 15 is used for blocking the through hole 14 for deflation, a piston 16 for inflating the hollow inner cavity 31 is slidably arranged in the valve core 15, and the piston 16 is fixed with the pull ring 12.

The end of the valve core 15 and the surface of the piston 16 are both provided with a one-way valve 18, the one-way valve 18 comprises a blocking ring 181 and a plurality of valves 182 which are mutually attached to form a disc shape, and the blocking ring 181 is positioned above the valves 182. When the valves 182 are kept at a horizontal plane, gaps among the valves are jointed and blocked to realize sealing, when pressure is received, the valves 182 deflect under the action of the pressure, so that the gaps among the valves are exposed, air circulates, and the blocking ring 181 is used for blocking the valves 182, so that the valves 182 keep the position of a horizontal plane.

The diameter of the piston 16 is larger than the diameter of the upper port of the valve core 15, and the length of the valve core 15 is shorter. The diameter of the piston 16 is larger than that of the upper port of the valve core 15, when the piston 16 is pulled by the pull ring 12 to the highest point of the valve core 15, the pull ring 12 drives the piston 16 to continuously rise, and the piston 16 drives the valve core 15 to rise, so that the valve core 15 is separated from the interference fit with the through hole 14, gas can flow out of the through hole 14, the rubber plug is quickly deflated, and the removal from the bottle mouth is convenient; the length of the valve core 15 is set to be short, so that the valve core 15 can be conveniently pulled outwards under the action of the pull ring 12.

The outer wall of the pull ring 12 is in interference fit with the inner wall of the groove 11, and a notch 111 is formed in the groove 11 relative to the connecting seat 13. Adopt interference fit between pull ring 12 and the recess 11 to just there is the damping between pull ring 12 and the recess 11, avoid pull ring 12 easily to rotate from the recess 11 and break away from, the setting up of breach 111 facilitates the user and mentions pull ring 12 from the recess 11.

The cover plate part 1 is provided with a raised ring 17 at a central position corresponding to the central hole 21 of the insertion part 2. The convex ring 17 is an external display of the central hole 21, and prompts the user of the inserted position, thereby facilitating the positioning of the user and avoiding the condition that the user inserts askew and slantwise.

The insertion part 2 is set to be conical, and a plurality of notches 22 are distributed at intervals. The ring shape of scarce groove 22 is arranged, and the interval sets up to can knead the front end of inserting portion 2, make the front end diameter littleer, conveniently insert in the less bottleneck of diameter, realize with the interference fit of bottleneck.

When inserting the medicine bottle, at first prepare the bottleneck with insertion part 2, then push down, wrap up peripheral portion 3 in the outside of bottleneck, later open through-hole 14 and carry out the gas injection to the cavity inner chamber 31 of peripheral portion 3, pack peripheral portion 3 for peripheral portion 3 wraps up the outer wall of bottleneck, later insert valve core 15 and block it in through-hole 14, and install pull ring 12 in the both sides of connecting seat 13, detain it in recess 11 simultaneously, make it and recess 11 between interference fit, accomplish the equipment to the medicine bottle.

When the gas is replenished, because the gas in the medicine bottle may be lost due to long-term placement of the medicine bottle, so that the gas is replenished to the hollow inner cavity 31 of the peripheral part 3, the pull ring 12 is firstly pulled upwards through the notch 111 to lift the pull ring 12 from the interference fit groove 11, and then through repeated small-amplitude lifting and pressing back, so that the inner side of the pull ring 12 carries the piston 16 and the piston 16 to continuously lift in the valve core 15, when the piston 16 lifts upwards, the one-way valve 18 on the piston 16, since the valves 182 are not blocked and thus all deflect downward, the gaps between each other are exposed to the incoming air, while the check valve 18 on the valve core 15, the valve core 15 is ready to be deflected upwards due to the action of the suction force caused by the upward movement of the piston 16, but is stopped by the upper stop ring 181, so that the original state is maintained, and air enters the valve core 15; when the piston 16 descends, the check valve 18 on the piston 16 is kept in the original state and cannot ventilate because the valve 182 is blocked by the blocking ring 181 on the upper part, and the check valve 18 on the valve core 15 on the lower part and the valve 182 deflect downwards under the action of pressure to open the gap between the two, so that air is injected into the hollow inner cavity 31 of the peripheral part 3, and the filling of the hollow inner cavity 31 is completed.

When the rubber plug needs to be taken down from the bottle opening, firstly, the pull ring 12 is lifted upwards through the notch 111 of the groove 11, then the pull ring 12 is pulled upwards, the pull ring 12 drives the piston 16 to move upwards until the piston moves to the upper end of the valve core 15, along with the continuous lifting, the pull ring 12 lifts the valve core 15 from the through hole 14, the through hole 14 is opened, the gas in the valve core is released, and then, the rubber plug is pulled outwards from the bottle opening by the continuous pulling.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
