Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and in particular to a highly sealing anti-counterfeiting cap for large water bottles that can prevent leakage due to compression. Background Technology

[0002] Bottled water, a common form of drinking water in modern life, offers several advantages. Its sealed design prevents secondary contamination during transportation and storage, making it safer and more hygienic compared to bulk water or repeatedly boiled tap water. Bottled water is ready to drink immediately: no boiling or cooling is required, making it suitable for quick access in homes, offices, schools, and other locations, especially for emergency drinking needs. Common bottled water sizes include 5L, 10L, 12L, and 18.9L, allowing users to choose according to the number of people and water usage frequency, avoiding waste. For homes or offices, the unit cost of bottled water may be lower than that of bottled water, especially when used in large quantities. It reduces plastic waste: compared to frequently buying small bottles of water, bottled water containers can be reused (requiring recycling and cleaning), reducing plastic consumption per use.

[0003] Current anti-counterfeiting caps for large water bottles have shortcomings in use. When the cap is squeezed and deformed, leakage is likely to occur, causing the entire bottled water to fail to seal and resulting in a significant waste of resources.

[0004] In view of this, the inventors hope to design a highly airtight anti-counterfeiting cap for large water bottles that can prevent leakage due to compression, thereby expanding its application scenarios. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a highly airtight anti-counterfeiting cap for large water containers that can prevent leakage due to compression.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A high-sealing anti-counterfeiting cap for large water bottles that can prevent leakage by squeezing includes a cap body composed of a cap top and a cap body. The cap body has a nozzle channel at the center of the cap top. The inner end of the nozzle channel has a sealing inner cap. The outer side of the sealing inner cap has a high-position guide protrusion and a low-position pressure-bearing protrusion. The sealing inner cap has a tear edge near the low-position pressure-bearing protrusion at the connection with the side wall of the nozzle channel. The top of the sealing cavity of the cap body has several supporting ribs along the circumference. A sealing sheet is snapped together between the supporting ribs and the sealing inner cap.

[0007] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water containers that can prevent leakage due to compression, the high-position guide protrusion is provided with a guide bevel on the side near the low-position pressure-bearing protrusion.

[0008] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water containers that can prevent leakage due to compression, the cap body is provided with an annular groove at the periphery of the nozzle channel.

[0009] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water containers that can prevent leakage due to compression, the upper side of the sealing sheet is provided with an arc-shaped groove that matches the shape of the annular groove, and the unconnected part of the arc-shaped groove is staggered from the position of the tear edge.

[0010] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water containers that can prevent leakage due to compression, the depth of the arc-shaped groove is less than the thickness of the sealing sheet, and the arc of the arc-shaped groove is 150–170°.

[0011] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water bottles that can prevent leakage due to compression, the top wall of the sealing cavity of the cap body is provided with several weight-reducing grooves along the circumferential direction.

[0012] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water bottles that can prevent leakage due to compression, the sealing cavity peripheral wall of the cap body is provided with sealing threads below the supporting rib plate, and the cap body is provided with anti-slip ridges on the outer side of the cap body.

[0013] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water containers that can prevent leakage due to compression, the inner side of the sealing inner cap is provided with a thickened connecting edge that is away from the low-pressure-bearing protrusion at the connection between the inner side of the sealing inner cap and the side wall of the nozzle channel.

[0014] Furthermore, in the aforementioned high-sealing anti-counterfeiting cap for large water containers that prevents leakage due to compression, the inner side of the sealing inner cap is flush with the top wall of the sealing cavity.

[0015] Furthermore, in the aforementioned highly airtight anti-counterfeiting cap for large water containers that prevents leakage due to compression, the sealing sheet is an aluminum foil sheet.

[0016] The beneficial effects of this utility model are: 1. Through the interlocking combination of the sealing inner cap, supporting ribs, and aluminum foil sealing sheet, a multi-layer sealing barrier is formed. When the bottle is squeezed and deformed, the sealing performance of the bottle mouth is greatly improved due to the sealing sheet, effectively preventing liquid leakage or the entry of external contaminants. In particular, the sealing sheet is made of aluminum foil, which combines flexibility and airtightness, and can adapt to pressure changes.

[0017] 2. The annular groove around the nozzle channel matches the arc-shaped groove of the sealing sheet, and the non-connected parts are staggered from the tear edge, so that the center part of the sealing sheet can be opened quickly with the inner sealing cover, and the center part of the aluminum foil will not detach after opening.

[0018] 3. The tear edge design of the sealed inner cover requires destructive opening. Combined with the irreversible damage characteristics of the aluminum foil sealing sheet, it ensures that it cannot be restored after the first opening, thus preventing counterfeiting during recycling.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
