Description

Bottle cap and bottle combined structure

Technical field

The invention relates to the technical field of storage containers, in particular to a bottle cap and a bottle combined structure.

Background technique

Medical medicine bottles are containers for packaging or loading medicines. They have high requirements for the packaging of bottle bodies and caps. Special medicines require special structure storage and packaging, such as canned freeze-dried products, which are being canned freeze-dried. When producing products, the injection bottle must be left open so that the product will be discharged when the product is freeze-dried and sublimated. After the filling is completed, the injection bottle must be closed as soon as possible to avoid all kinds of drugs in the air. Safe substances re-enter the bottle, so it is necessary to adopt a combined structure of injection bottles specially used for canned freeze-dried products.

In the bottle structure for canned freeze-dried products disclosed in the prior art, the bottle cap body is provided with a medicine taking port, and the cover plate is connected with the bottle cap body through a connecting piece. After the medicine is filled in the bottle, the cover plate needs to be turned over. At the same time, the connector is bent and the cover plate is fastened on the medicine taking port to complete the package. Since most of the medical bottle caps are injection molded products, the injection molded product itself has a certain degree of elasticity. After bending, in order to avoid springback, the package is not firm. The bending part is set very thin, but the low temperature resistance of the plastic is poor, it becomes brittle at low temperature, and it is easy to break when bending, which affects the yield.

Moreover, with the increase in the value of medicines, counterfeiting and secondary use have occurred from time to time, which not only harms the health of patients, but also has a negative impact on manufacturers and hospitals. In the prior art, the cover plate has no change in appearance after being opened and closed. When opened, the structure of the partial self-destruction and detachment of the lock is very subtle and not easy to detect. The cover can be easily attached by simple glue dispensing. The plate is closed twice, so it is easy for criminals to reuse the empty medicine bottle, or steal a small amount of medicine from the feeding port and repackage it for sale, resulting in insufficient medicine amount and a potential safety hazard.

In this embodiment, the take-out port 10 has a keyhole shape, the shape of the pull tab 2 matches the shape of the take-out port 10, and the thickness of the pull tab 2 The thickness is the same as the top wall. At the same time, the upper surface and the lower surface of the pull tab 2 are arranged flush with the corresponding outer surface and inner surface of the top wall respectively, which can prevent the pull tab 2 from protruding from the bottom surface of the top wall to make the sealing body ( (Not shown in the figure) exerting force on the pull tab 2 or protruding from the upper surface of the top wall, the pull tab 2 is squeezed by external objects during installation or transportation, causing the pull tab 2 to be damaged. In this embodiment, the sealing body is a rubber plug, and the sealing body can also be a silicone plug or the like, depending on specific needs.

In the radial direction, an equidistant gap is left between the side wall surface of the pull tab 2 and the top wall, and the self-destruct part is arranged in the gap. In this embodiment, the self-destruct part is a thin-shaped self-destruct strip 3. 3 Set up multiple, such as five, distributed in the gap at intervals, and fix the pull tab 2 to the top wall. In this embodiment, the pull tab 2 and the self-destruct strip 3 are integrally formed on the reclaiming port 10, so that Before the material is taken, the reclaiming port 10 is always in a state of being covered by the pull tab 2. Since the pull tab 2 does not need to be packaged after the bottle is filled, the pull tab 2 is prevented from being damaged by force and the yield of the product is improved; In addition, the pull tab 2 and the self-destruction part are integrally formed on the reclaiming port 10. When the reclaiming port 10 is opened, the pull tab 2 must be pulled to cause the self-destructing part to be broken and damaged. Secondary utilization improves the safety and reliability of the use of bottle caps.
