Description
Technical Field
The utility model relates to a food and drug packaging field, concretely relates to bottle lid suitable for there is not gasket to seal.
Background
At present, plastic bottle caps for food, beverage and medicine are manufactured by adopting an injection molding cap manufacturing technology in most food and medicine industries. Particularly, in the pharmaceutical packaging industry, the detection requirement of the national food and drug administration on a heat-seal gasket bottle for pharmaceutical packaging is that the heat-seal gasket bottle does not leak gas within 3 minutes under the condition that the vacuum degree is negative 27kpa under the condition that the heat-seal gasket is not contained, and the detection requirement is difficult to achieve after the existing packaging bottle and bottle cap are matched. On the other hand, when the medicine is packaged and delivered from a factory, the bottle mouth needs to be subjected to aluminum foil heat sealing, but the existing bottle cap is frequently subjected to sealing leakage in the heat sealing process, so that the qualified rate of sealed products is low.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides a bottle lid suitable for there is not gasket seal, it can realize that elasticity compresses tightly bottleneck or heat-seal gasket, increases the qualification rate of heat-seal, realizes the sealed of no gasket simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a bottle lid suitable for there is not sealed of gasket which characterized in that: the bottle cap comprises a bottle cap body, wherein an elastic pressing ring is arranged on the inner top surface of the bottle cap body, the elastic pressing ring is a thin-wall ring which protrudes downwards from the inner top surface of the bottle cap body and extends along an arc line or a folding line, and the diameter of the lower port edge of the elastic pressing ring is equal to the diameter of a bottle opening matched with the bottle cap body; the bottle cap comprises a bottle cap body and is characterized in that a convex ring is arranged on the inner side wall of the bottle cap body, the convex ring is located on the upper portion of the inner wall of the bottle cap body, and a gap is reserved between the convex ring and the lower end face of the elastic pressing ring.
Furthermore, the inner side wall of the bottle cap body is provided with an internal thread matched with the external thread of the bottle mouth.
Furthermore, the outer side wall of the bottle cap body is provided with anti-skid grains, and the anti-skid grains are vertical convex ridges distributed on the circumference of the outer side of the bottle cap body.
Further, the convex ring is a semicircular ring protruding towards the inner side of the bottle cap body.
Furthermore, the top surface of the outer side of the bottle cap body is provided with a sinking platform.
The beneficial effects of the utility model include: compress tightly the sealed of bottleneck realization no gasket through the elasticity clamping ring, on the other hand the elasticity clamping ring plays the pre-compaction effect and can increase the hot-seal success rate of gasket heat-seal when having the heat-seal gasket, is provided with the bulge loop of spacing heat-seal gasket in the bottle lid for the heat-seal gasket is difficult for dropping, is difficult for appearing the crooked phenomenon of heat-seal simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
A bottle cap suitable for gasketless sealing as shown in fig. 1 includes a cap body 1 provided on a bottle body 6. The bottle cap comprises a bottle cap body 1 and is characterized in that an elastic pressing ring 2 is arranged on the inner top surface of the bottle cap body 1, the elastic pressing ring 2 is of a structure that a thin-wall ring protrudes downwards from the inner top surface of the bottle cap body 1 and integrally injection-molded with the bottle cap body 1, the elastic pressing ring 2 can extend along an arc line or a folding line to form a thin wall, and can elastically deform when being pressed to generate elastic force so as to compress a bottle opening or arrange a heat-seal gasket 5 on the bottle opening. The diameter of the lower port edge of the elastic compression ring 2 is equal to the diameter of the bottle mouth matched with the bottle cap body 1, and the elastic compression ring can be completely contacted with the bottle mouth under the condition of no heat-sealing gasket, so that the detection condition that no air leakage phenomenon occurs within 3 minutes under the condition that the vacuum degree is negative 27kpa is met. The bottle cap is characterized in that a convex ring 3 is arranged on the inner side wall of the bottle cap body 1, the convex ring 3 is located on the upper portion of the inner wall of the bottle cap body 1, and a gap is reserved between the convex ring 3 and the lower end face of the elastic pressing ring 2. The internal diameter of bulge loop 3 slightly is less than the external diameter of heat-seal gasket 5, and heat-seal gasket 5 is in the clearance between bulge loop 3 and elastic compression ring 2 just when unscrewing the bottle lid, and can not drop. The bulge loop 3 is to the protruding semicircle ring in 1 inboard of bottle lid body, and on the other hand bulge loop 3 plays a guide effect to heat-seal gasket 5 for heat-seal gasket 5 does not take place to be crooked for the bottleneck when the heat-seal, thereby produces the phenomenon that influences the encapsulation outward appearance.
The inner side wall of the bottle cap body 1 is also provided with an internal thread matched with the external thread of the bottle mouth.
In order to facilitate the opening or screwing of the bottle cap body 1 relative to the bottle body 6, anti-slip threads 4 are arranged on the outer side wall of the bottle cap body 1, and the anti-slip threads 4 are vertical protruding ridges distributed along the outer side circumference of the bottle cap body 1.
The top surface of the outer side of the bottle cap body 1 is provided with a sinking platform which can be used for sticking product labels or branding characters or numbers related to products on the sinking platform.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
