Description

Technical Field

[0001] This utility model belongs to the field of container technology and relates to high-safety bottle caps. Background Technology

[0002] Existing metal cap technologies have shortcomings in comprehensively considering sealing and safety performance. For example, ordinary metal caps may only use a single gasket structure, resulting in limited sealing effectiveness and a lack of effective explosion-proof design. When the product inside the container deteriorates, causing an increase in internal pressure, it may lead to safety issues, such as the metal cap suddenly bursting open and injuring consumers. Furthermore, the fit between the gasket and the metal cap is not efficient or secure enough, affecting overall performance. These problems, to some extent, limit the application effectiveness and safety of metal caps in related products. Summary of the Invention

[0003] The purpose of this invention is to provide a high-safety bottle cap that can solve the above-mentioned problems and effectively protect consumer safety.

[0004] According to the technical solution provided by this utility model: a high-safety bottle cap includes a bottle cap, a number of vent holes on the upper part of the bottle cap, a gasket placed on the top of the bottle cap, a sealing layer coated on the bottom of the gasket, a support piece in the vent hole, the support piece being connected to the vent hole, and the support piece extending towards the inner circumference of the bottle cap to support the sealing layer.

[0005] As a further improvement to this utility model, the bottle cap is made of metal.

[0006] As a further improvement of this utility model, the lower inner circumference of the bottle cap is provided with a threaded structure.

[0007] As a further improvement of this utility model, an opening protrusion ring is provided on the outer periphery of the bottle cap.

[0008] As a further improvement of this utility model, the exhaust hole is rectangular.

[0009] As a further improvement of this utility model, the bottom of the gasket has a frosted surface.

[0010] As a further improvement of this utility model, the gasket is smaller than the bottle cap.

[0011] As a further improvement of this utility model, the sealing layer is made of thermoplastic elastomer and is molded onto the frosted surface of the bottom of the gasket through a molding process.

[0012] As a further improvement of this utility model, the tray is a curved rectangle, with the upper end of the tray connected to the vent hole and the lower end of the tray extending towards the inner circumference of the bottle cap.

[0013] As a further improvement of this utility model, an explosion-proof opening is provided on the bottle cap.

[0014] The positive and progressive effects of this application are as follows:

[0015] 1. The sealing layer coated on the bottom of the gasket of this utility model improves the sealing effect. The gasket is placed inside the bottle cap by a support plate, ensuring the stability of the structure.

[0016] 2. The molding process of the sealing layer of this utility model enables it to be tightly bonded to the gasket, further enhancing the sealing performance.

[0017] 2. The explosion-proof port of this utility model provides a safety guarantee for the container, and can release pressure in time when the internal pressure rises abnormally, effectively protecting the safety of consumers. Attached Figure Description

[0022] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this utility model described herein. Furthermore, terms such as "comprising" and "having" mean that in addition to those already listed in "comprising" and "having," other unlisted contents may also be included; for example, a process, method, system, product, or device may include a series of steps or units, not necessarily limited to those steps or units that have been clearly listed, but may include other steps or units that have not been clearly listed or are inherent to these processes, methods, products, or devices.

[0025] Due to the angle of the drawing, some parts may not be drawn, but their positions and connections can be understood from the text descriptions.

[0026] like Figures 1-2 As shown, this utility model is a high-safety bottle cap, including a bottle cap 1, a number of vent holes 2 on the upper part of the bottle cap 1, a gasket 3 placed on the top of the bottle cap 1, a sealing layer 4 coated on the bottom of the gasket 3, and a support piece 6 in the vent hole 2, which supports the sealing layer 4.

[0027] The bottle cap 1 is made of metal and has a threaded structure on the lower inner circumference for connection with the beverage bottle.

[0028] The bottle cap 1 has an opening protrusion ring 1-1 on its outer periphery, which makes it easy to rotate the bottle cap 1 to separate it from the beverage bottle.

[0029] The vent 2 is rectangular. The vent 2 ensures that the gas in the beverage bottle can escape from the vent 2 when the bottle cap 1 is opened, thus preventing the gas in the beverage bottle from popping the bottle cap 1 out.

[0030] The bottom of the gasket 3 has a frosted surface, which can enhance the connection strength with the sealing layer 4.

[0031] The gasket 3 is smaller than the bottle cap 1 to prevent it from bending when placed inside the bottle cap 1.

[0032] The sealing layer 4 is made of thermoplastic elastomer and is molded onto the frosted surface at the bottom of the gasket 3 through a molding process.

[0033] like Figure 4 As shown, the support plate 6 is a curved rectangle. The upper end of the support plate 6 is connected to the vent 2, and the lower end of the support plate 6 extends towards the inner circumference of the bottle cap 1.

[0034] When a beverage bottle contains a perishable liquid, to prevent the liquid from deteriorating and generating gas, which could break the connection between the bottle cap 1 and the beverage bottle, causing the bottle cap 1 to suddenly fly off, the bottle cap 1 is equipped with an explosion-proof vent 5. Figure 3 As shown.

[0035] The explosion-proof port 5 has a larger opening area than the vent port 2, providing better venting capability.

[0036] In this embodiment, one explosion-proof port 5 and seven vent holes 2 are evenly distributed on the upper part of the bottle cap 1.

[0037] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
