Anti-leakage sealing bottleneck structure for canned water

Abstract

The invention relates to an anti-leakage sealing bottle structure for canned water, comprising a bottleneck (2). The anti-leakage sealing bottle structure is characterized in that the upper part or the middle part of the inner side wall (2-1) of the bottleneck (2) is provided with an arc-shaped concave ring (2-1-1); the joint part of the inner side wall (2-1) and the top part of the bottleneck (2) is shaped like an R arc-shaped ring (R1); the joint part of the outer side wall (2-2) and the top part of the bottleneck (2) is shaped like an R arc-shaped ring (R2); the upper part or the middle part of the outer side wall (2-2) of the bottleneck (2) is provided with an R arc-shaped ring (R3); an R arc-shaped convex ring (2-3) is formed between the R arc-shaped ring (R1) and the R arc-shaped ring (R3); and the lower part of the R arc-shaped ring (R3) is provided with a concave ring (2-4). The anti-leakage sealing bottle structure has the effects of double sealing, anti-leakage, anti-counterfeit and long shelf life, reduces the weight and volume of a bottle body, reduces the use amount and loss of raw materials, saves the energy and protects the environment. The anti-leakage sealing bottle structure for canned water is widely applicable to canned water with five-gallon specification and other various specifications.

Description

technical field [0001] The invention relates to a bottle mouth for bottled water, in particular to an anti-leakage sealing bottle mouth structure for bottled water, which is suitable for bottle sleeves of five gallons or other specifications. It belongs to the technical field of plastic bottle structure. Background technique [0002] At present, edible bottled water is accepted by more and more people. The quality of edible water is not only related to the water quality of the water source, but also related to whether the edible bottled water leaks and is artificially polluted during transportation. When bottled water leaks, bacteria or other contaminants can enter the water, causing damage to water quality. Bottled water bottle structure of the prior art mainly has the following two defects: [0003] (1) Easy to leak. The cause of the leakage of edible barreled water is that the connection between the bottle cap and the bottle mouth is loosened or a gap occurs, mainly du...

AI Technical Summary

Problems solved by technology

The reason for the leakage of edible bottled water is that the connection between the bottle cap and the bottle mouth is loose or there is a gap, which is mainly caused by the unreasonable structure of the bottle mouth in the prior art.

To sum up, the main reason is that there is only a single-point seal at the connection between the bottle cap and the bottle mouth, and the R arcs of the two cannot be matched and docked, so the R position of the bottle cap and the bottle mouth cannot be tightly sealed, and it is often handled manually. Holding the bottle cap will cause the bottle mouth to loosen, resulting in slight water leakage, or vibration during transportation will cause the connection between the bottle cap and the bottle mouth to loosen, resulting in water leakage

[0004] (2) Due to the unreasonable structure of the bottle mouth, the bottle caps used together with it are large in size, heavy in weight, consume a lot of raw materials, and cost high

[0005] In the existing technology, the operating manufacturers face the severe test of market competition. Due to the unsolved problems of water leakage and bacterial entry, the manufacturers have different degrees of damage and lose the possibility of receiving orders, and there is a lot of waste.
