Description
Technical Field
The invention relates to a rust-proof easy-to-open metal cover with threads, and relates to the field of container packaging and sealing.
Background
There are two popular types of metal closures with molded sealant layers.
The first metal molding bottle cap is characterized in that the molding mold shape is changed in the molding process, so that the molding adhesive layer is threaded and matched with the bottle mouth, and the edge of the bottom of the bottle cap is provided with a curled edge which is outwards in the radial direction. The bottle cap has the advantages that the friction coefficient between the adhesive layer and the glass is small, so that the bottle cap is easy to open, and meanwhile, as no metal is in direct contact with the bottle cap, the metal surface is not worn, and therefore, the metal part is not easy to rust. However, the bottle cap has the defects that the thread is formed by the molding adhesive layer completely, the elasticity is high, the strength is low, the elastic deformation is easy to generate under the condition of external force, the matching deviation and even the separation of the thread and the bottle mouth are generated, in addition, the technical complexity is higher in the molding process for better matching with the bottle mouth, and compared with the similar products, more molding silica gel is used for generating the thread, more raw materials are used, and the waste is caused.
The second type of metal molded closure, which completely eliminates the use of a molding compound on the metal sidewall of the closure, provides the metal sidewall with threads that mate with the finish by the closure process, and is also provided with a bead on the bottom edge of the closure, directed radially outwardly. The bottle cap has the advantages that the structural strength of the metal is high, so that the screw threads generated by the side wall of the metal are more firmly matched with the screw threads of the bottle mouth, the phenomenon of poor matching or falling off can not be generated, and meanwhile, compared with the first bottle cap, the bottle cap is simpler to produce and the used raw materials are relatively less. However, the bottle cap has the defects that the bottle cap can damage the protective outer layer of metal due to the fact that threads generated on the side wall of the metal are in direct contact with the bottle mouth, so that the metal is more prone to rust, and meanwhile, the friction coefficient between the metal and glass is larger than that between silica gel and the metal in the actual use process, so that the bottle cap is not prone to being twisted.
The disadvantage common to both metal molded closures is that the possibility of rust is greater because the metal rim inside the bead is more accessible to the outside environment due to the radially outward direction of the bead of the bottom rim, and the metal rim has no metal protective outer layer.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a threaded rust-proof easy-to-open metal cover, which has the following technical scheme:
The utility model provides a take rust-resistant easy-open metal lid of screw thread, includes the lid, the lid includes the metal lid and installs the sealed silica gel cover in the metal lid, the metal lid include the top and with top integrated into one piece's skirt the center at top is provided with the sealed elastic pad that corresponds with sealed silica gel cover, the bottom edge of skirt is provided with the turn-up with skirt integrated into one piece, the radial setting of skirt is followed to the turn-up, is provided with skirt internal thread at the inner wall of this skirt, the inner wall of sealed silica gel cover is provided with sealed silica gel cover internal thread, this sealed silica gel cover internal thread and the external screw thread screw-thread cooperation of bottle bottleneck department, seals after sealed silica gel cover is to bottle bottleneck cover is lived under the extrusion of metal lid.
After the curled edge extends outwards to form an outer bulge, the curled edge is bent inwards to form an inner bulge, and the free end of the curled edge is contacted with the inner wall of the curled edge.
The inner bulge of the curled edge is positioned on the outer side of the skirt part and tangential to the skirt part.
The internal thread of the sealing silica gel sleeve is positioned between the internal thread of the skirt part and the external thread at the bottle mouth of the bottle body, so that the internal thread of the skirt part is prevented from being in direct contact with the external thread at the bottle mouth of the bottle body, and the sealing between the metal cover and the bottle mouth of the bottle body is realized.
The sealing silica gel sleeve is made of silica gel, and after the bottle body is sealed, the sealing elastic pad is sunken downwards along with the sealing silica gel sleeve under the action of negative pressure in the bottle body; when the bottle body seal is broken or the sealed object generates gas, the sealing elastic pad is sprung upwards along with the sealing silica gel sleeve.
The invention has the advantages that:
1. is not easy to rust. Since the bead is radially inward, the edge of the metal cap is relatively less exposed to the external environment and thus the edge of the metal cap is less likely to rust. In addition, compared with the second background technology, the sealing silica gel sleeve isolates the metal outer cover from the bottle mouth, so that the internal thread of the metal outer cover and the external thread of the bottle mouth are prevented from directly rubbing, the metal cover is protected, rust is prevented, and the rust resistance is better. And secondly, the valve is easy to open. Because the internal thread of the sealing silica gel sleeve is in direct contact with the thread of the bottle mouth, the friction coefficient is smaller, and the sealing silica gel sleeve is easier to twist open when in use.
3. The sealing effect is better. The sealing silica gel sleeve is used for completely coating the bottle mouth, so that poor sealing is prevented. Meanwhile, the metal cover provides structural strength, so that the matching strength of the skirt internal threads and the bottle mouth external threads is enhanced, and the sealing stability is enhanced.
4. The production process is simple and convenient, and the material is saved. The screw thread is produced through the conventional sealing process, the process is simpler, and meanwhile, the silica gel required for producing the screw thread can be saved, so that the material is saved.
