Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and in particular to a large-diameter anti-counterfeiting sealing cap that prevents leakage. 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, 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] Many bottled water containers on the market today are prone to damage during production or filling due to their weight, sometimes resulting in large chips at the opening. Using a single PE cap often fails to provide a proper seal, severely impacting production efficiency and reducing product defect rates. Furthermore, these PE caps lack a pressurized ejection channel, making them difficult to open when installed in a water dispenser.

[0004] In view of this, the inventors hope to design a leak-proof, large-diameter, anti-counterfeiting sealing cap that can compensate for the defect of the bottle opening having a gap, while reducing the opening operation when it is installed in the water dispenser. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and provide a leak-proof, large-diameter, anti-counterfeiting sealing cap.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A leak-proof, large-diameter, anti-counterfeiting sealing cap includes a cap and a notch covering component. The cap includes a cap body, the top of which has an ejection channel, and the bottom of which has a top plate. The outer side of the top plate has pressure protrusions near its edge, and the connection between the top plate and the ejection channel has easily breakable thin edges distributed near the pressure protrusions. A raised ring is installed on the inner side of the cap body on the top plate. The raised ring and the periphery of the cap body together form a covering component installation area, in which a notch covering component for covering the notch at the edge of the barrel mouth is installed.

[0007] Furthermore, in the aforementioned leak-proof large-diameter anti-counterfeiting sealing cap, an anti-counterfeiting ring is provided at the bottom of the periphery of the cap body.

[0008] Furthermore, in the aforementioned large-diameter anti-counterfeiting sealing cap, the outer periphery of the cap body is provided with anti-slip ridges for easy twisting.

[0009] Furthermore, in the aforementioned leak-proof large-diameter anti-counterfeiting sealing cap, the inner periphery of the cap body is provided with sealing threads.

[0010] Furthermore, in the aforementioned large-diameter anti-counterfeiting sealing cap, the lower side of the top plate of the cap body is provided with an anti-detachment connecting strip that connects to the ejection channel, and the connection point is positioned opposite to the easily broken thin edge.

[0011] Furthermore, in the aforementioned large-diameter anti-counterfeiting sealing cap for preventing leakage, the notch covering is composed of a top sealing part and a side sealing part. One end of the top sealing part is connected to the upper end of the side sealing part, and the other end of the top sealing part abuts against the convex ring.

[0012] Furthermore, in the aforementioned leak-proof large-diameter anti-counterfeiting sealing cap, the cap is made of PE material.

[0013] Furthermore, in the aforementioned leak-proof large-diameter anti-counterfeiting sealing cap, the notch covering is made of TPE material.

[0014] The beneficial effects of this utility model are: 1. The leak-proof large-diameter anti-counterfeiting sealing cap provided by this utility model, after being tightened with the water bottle, has its top sealing part of the notch cover fitting with the end face of the bottle opening, and its side sealing part fitting with the outside of the bottle opening; when there is a notch in the bottle opening, the notch cover can be covered by the interference fit between the notch cover and the bottle opening, thus achieving a sealing effect.

[0015] 2. When a water bucket equipped with the leak-proof large-diameter anti-counterfeiting sealing cap provided by this utility model is put into a water dispenser, the outer side of the top plate at the inner end of the ejection channel is provided with a pressure protrusion. When the top pipe of the water dispenser comes into contact with the pressure protrusion, it can exert greater pressure on the easily broken thin edge, causing the top plate to tear from the ejection channel. At the same time, the design of the anti-detachment connecting strip can prevent the top plate from completely tearing and detaching.

[0016] 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

A raised ring 109 is installed on the inner side of the cap body 101 within the top plate 105. The raised ring 109 and the periphery of the cap body 101 together form a covering component installation area 110. A notch-covering component 2 for covering the notch at the edge of the barrel opening is installed in the covering component installation area 110.

[0021] In this embodiment, an anti-counterfeiting ring 102 is provided at the bottom of the periphery of the cover body 101.

[0022] In this embodiment, the outer periphery of the cover body 101 is provided with anti-slip ridges 103 for easy twisting, and the inner periphery of the cover body 101 is provided with sealing threads 108.

[0023] In this embodiment, the lower side of the top plate of the cover body 101 is provided with an anti-detachment connecting strip that is connected to the ejection channel 104, and the connection point is set opposite to the easily broken thin edge 107.

[0024] In this embodiment, the notch cover 2 is composed of a top sealing part 201 and a side sealing part 202. One end of the top sealing part 201 is connected to the upper end of the side sealing part 202, and the other end of the top sealing part 201 abuts against the convex ring 109.

[0025] In this embodiment, the cover 1 is made of PE material.

[0026] In this embodiment, the notched cover 2 is made of TPE material.
