Technical Field

[0001] This application relates to the field of bottle cap technology, and more particularly to a multi-seal bottle cap and bottle. Background Technology

[0002] Wine bottle caps typically consist of an outer cap assembly and an inner stopper assembly located within the outer cap assembly, serving a sealing function. However, existing wine bottle caps often have poor sealing performance, easily leading to leakage or seepage of wine, resulting in short shelf life and affecting the quality of the wine.

[0003] Therefore, improving the sealing performance of bottle caps is a technical problem that urgently needs to be solved. Utility Model Content

[0004] To address the aforementioned issues, this application provides a multi-layered sealing bottle cap with multiple sealing structures, resulting in excellent sealing performance.

[0005] To solve the above problems, the technical solution adopted in this application is: On the one hand, this application provides a multi-seal bottle cap, including a bottle mouth disposed on the outside of the bottle opening and an inner cap sealed outside the bottle mouth, wherein a valve plate is press-fitted inside the inner cap, and the inner cap and the valve plate are tightly fitted together to form a first sealing area; The lower end of the valve plate is pressed into the valve core, the lower end of the valve core is provided with a glass bead, an inner plug is fitted on the bottle mouth, the inner plug is located inside the bottle mouth, and the upper part of the inner plug is tightly fitted with the valve core to form a second sealing area. The middle part of the inner plug fits tightly against the bottle opening to form a third sealing area; The lower part of the inner plug fits tightly against the glass bead to form a fourth sealing area.

[0006] In one possible implementation of this application, a lower sleeve is press-fitted onto the bottle neck, an upper cover is press-fitted onto the lower sleeve, and the inner cover is located inside the upper cover.

[0007] In one possible implementation of this application, the number of glass beads is one or more.

[0008] In one possible implementation of this application, the inner cover includes a vertically arranged protrusion, the valve plate includes a horizontally arranged portion, and the protrusion and the horizontal portion are tightly fitted together.

[0009] In one possible implementation of this application, the inner plug includes a vertically arranged first portion located inside the bottle mouth.

[0010] In one possible implementation of this application, the inner plug includes a second portion that is inclined toward the valve core and is in close contact with the valve core.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication of two components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0017] The following describes in further detail a multi-seal bottle cap provided in this embodiment with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] Please refer to Figure 1 and combined Figure 2 A multi-seal bottle cap includes a bottle nozzle 5 located outside the bottle mouth 9 and an inner cap 2 encapsulated outside the bottle nozzle 5. A valve plate 3 is press-fitted inside the inner cap 2, and the inner cap 2 and the valve plate 3 are tightly fitted together to form a first sealing area 10. The lower end of the valve plate 3 is pressed into a valve core 4, and a glass bead 7 is provided at the lower end of the valve core 4. An inner plug 6 is fitted onto the bottle mouth 9, and the inner plug 6 is located inside the bottle nozzle 5. The upper part of the inner plug 6 is tightly fitted with the valve core 4 to form a second sealing area 11. The middle part of the inner plug 6 is tightly fitted with the bottle mouth 9 to form a third sealing area 12. The lower part of the inner plug 6 is tightly fitted with the glass bead 7 to form a fourth sealing area 13.

[0019] Specifically, such as Figure 1 As shown, and in combination Figure 2 The device includes a bottle mouth 5 located outside the bottle opening 9 and an inner cap 2 encapsulated outside the bottle mouth 5. A valve plate 3 is pressed into the inner cap 2, and the lower end of the valve plate 3 is pressed into a valve core 4. A glass bead 7 is provided at the lower end of the valve core 4. An inner plug 6 is fitted onto the bottle opening 9 and is located inside the bottle mouth 5. The inner cap 2 and the valve plate 3 are tightly fitted together to form a first sealing area 10. The upper part of the inner plug 6 is tightly fitted together with the valve core 4 to form a second sealing area 11. The middle part of the inner plug 6 is tightly fitted together with the bottle opening 9 to form a third sealing area 12. The lower part of the inner plug 6 is tightly fitted together with the glass bead 7 to form a fourth sealing area 13.

[0020] like Figure 2As shown, in the first sealing zone 10, the inner cover sealing sheet, after being internally compressed with an interference fit, enhances the sealing function under the support of the outer diameter of the valve plate, ensuring long-term storage. Simultaneously, the inner cover sealing sheet undergoes plastic solidification under long-term sealing, ensuring the valve plate maintains its sealing function even during secondary resealment. In the second sealing zone 11, the inner plug sealing sheet seals against the inside and outside of the valve core groove under strong pressure. In the third sealing zone 12, the inner plug sealing surface enhances the sealing function under the strong support of the valve core, ensuring long-term storage. In the fourth sealing zone 13, the glass bead, through the connection between the valve plate and the valve core, forms a strong pressure interference seal with the inner plug opening.

[0021] As can be seen, the embodiments of this application enhance the sealing performance through two components: the valve core and the valve plate. Compared with the prior art, the design features a four-fold leak-proof structure, resulting in a superior sealing effect and enabling long-term storage. First, the valve plate and the inner cap form the first seal; second, the inner plug is inserted into the groove of the valve core, forming the second seal; third, the inner plug's sealing surface adheres to the bottle opening, forming the third seal; finally, the valve core presses against the glass bulb, creating a fourth seal between the glass bulb and the inner plug. This four-fold sealing structure significantly improves the bottle cap's sealing performance, enhances the sealing function, and ensures long-term storage.

[0022] In one optional embodiment, a lower sleeve 8 is pressed onto the bottle opening 9, and an upper cover 1 is pressed onto the lower sleeve 8, with the inner cover 2 located inside the upper cover 1.

[0023] Specifically, such as Figure 3 As shown, a lower sleeve 8 is press-fitted and fixed to the outer periphery of the bottle mouth 9. The upper outer edge of the lower sleeve 8 is press-fitted and fixed to the upper cover 1 through a ring buckle structure. The inner cover 2 is coaxially disposed in the inner cavity of the upper cover 1 and is limited by the inner wall of the upper cover 1 to prevent axial dislodgement.

[0024] In one alternative implementation, the number of glass beads 7 is one or more.

[0025] Specifically, the number of glass beads 7 can be adjusted according to the usage scenario, and this application does not limit this. One or more glass beads are within the protection scope of this application.

[0026] In one alternative embodiment, the inner cover 2 includes a vertically arranged protrusion 21, and the valve plate 3 includes a horizontally arranged horizontal portion 31, with the protrusion 21 and the horizontal portion 31 closely fitted together.

[0027] Specifically, such as Figure 4 As shown, the inner cover 2 includes a vertically arranged protrusion 21, and the valve plate 3 includes a horizontally arranged horizontal portion 31. The protrusion 21 and the horizontal portion 31 fit tightly together. The horizontally arranged horizontal portion 31 of the valve plate 3 can prevent splashing when opening the lid and pouring wine.

[0028] In one alternative embodiment, the inner plug 6 includes a vertically arranged first part 61 located inside the bottle mouth 5.

[0029] In one alternative embodiment, the inner plug 6 includes a second part 62 that is inclined toward the valve core 4 and is in close contact with the valve core 4.

[0030] In one alternative embodiment, the inner plug 6 includes a vertically arranged third part 63 located inside the bottle opening 9, and the third part 63 is in close contact with the bottle opening 9.

[0031] In one alternative embodiment, the inner plug 6 includes a fourth portion 64 disposed at an angle toward the glass bead 7, the fourth portion 64 being in close contact with the glass bead 7.

[0032] As can be seen, this application enhances the sealing performance through two components: the valve core and the valve plate. Compared with existing technologies, it features a four-fold leak-proof structure, resulting in a superior sealing effect and enabling long-term storage. First, the valve plate and the inner cap form the first seal; second, the inner stopper engages with the groove in the valve core, forming the second seal; third, the inner stopper's sealing surface adheres to the bottle neck, forming the third seal; finally, the valve core holds the glass bulb in place, creating a fourth seal between the glass bulb and the inner stopper. This four-fold sealing structure significantly improves the bottle cap's sealing performance, enhances the sealing function, and ensures long-term storage.

[0033] On the other hand, this application provides a bottle including the multi-sealed cap described in the first aspect.

[0034] Specifically, this application does not limit the use of the bottle; wine bottles, medicine bottles, and other bottles are all within the scope of protection of this application. Furthermore, this application does not limit the material or the shape of the bottle cap; any material or shape falls within the scope of protection of this application.
