Problems solved by technology

After many consumers buy beverages, especially large bottles of beverages, they often cannot drink them all in one gulp, and it is also an unhealthy way to drink beverages in one gulp, so they will store them after drinking
As mentioned above, there are gaps in the threaded connection structure, which are prone to infection and reproduction of bacteria during beverage transportation and storage
Therefore, when the consumer buys the beverage and drinks it directly, the bacteria will be eaten by mistake when the mouth touches the thread. What is even more frightening is that when the consumer drinks and stores it and then drinks it directly, it will cause a greater secondary accidental ingestion of bacteria. Phenomenon
If consumers buy beverages, they need to clean the threaded mouth again, which makes it extremely inconvenient to drink beverages. However, if they do not clean, they will often contact the threaded mouth contaminated by bacteria, which will affect their health.

Embodiment 1

[0031] Such as figure 1 As shown, a container mouth packaging structure with two layers of sealing caps is composed of a container mouth 300, an inner sealing cap 200 and an outer sealing cap 100;

[0032] The outer wall of the container mouth 300 is sequentially provided with external threads and anti-theft bosses 310 from the opening to the bottle body;

[0033] The inner surface of the side wall of the inner sealing cover 200 is provided with an internal thread, and the inner surface of the top is provided with an annular sealing groove 400;

[0034] The inner sealing cap 200 is screwed into the container mouth 300 through the internal thread and sleeved on the outside of the container mouth 300, and the upper end of the container mouth 300 is engaged in the annular sealing groove 400 to form a first sealing structure;

[0035] The outer sealing cover 100 is sleeved on the outside of the inner sealing cover 200 , and a second sealing structure is provided between its side ...

Embodiment 2

[0043] Such as figure 2As shown, the difference from Embodiment 1 is that the second sealing structure consists of an annular groove 520 arranged on the outer wall of the container mouth 300 and an annular protrusion arranged on the inner surface of the side wall of the outer sealing cover 100 . The ring-shaped boss 511 is engaged with the ring-shaped groove 520 .

Embodiment 3

[0045] Such as image 3 As shown, the difference from Embodiments 1 and 2 is that the second sealing structure consists of annular grooves 520 and 510 arranged on the outer wall of the container mouth 300 and the inner surface of the side wall of the outer sealing cover 100, and The elastic sealing ring 530 is composed of the inner ring of the elastic sealing ring 530, which is tightly engaged in the annular groove 520 provided on the outer wall of the container mouth 300, and the ring on the inner surface of the side wall of the outer sealing cover 100 The groove 510 is engaged with the outer ring of the elastic sealing ring 510 . And the elastic sealing ring 530 is a rubber ring. After the second sealing structure is opened and closed for a long time, the elastic sealing ring 530 will be worn due to friction, and the rubber ring is elastic and easy to install and replace. Rubber rings are also common, so the replacement process is more convenient.

Abstract

The invention relates to the field of threaded-mouth container packaging, in particular to a container mouth packaging structure with two layers of sealing covers. The container mouth packaging structure is composed of a container mouth, the inner sealing cover and the outer sealing cover. The outer wall of the container mouth is provided with an external thread and an anti-theft boss in sequence from the opening to the body. The inner surface of the side wall of the inner sealing cover is provided with an internal thread, and the inner surface of the top of the inner sealing cover is provided with an annular sealing groove. The inner sealing cover is screwed onto the container mouth in a sleeving mode through the external thread, the upper end of the container mouth is clamped into the annular sealing groove, and then a first sealing structure is formed. The inner sealing cover is sleeved with the outer sealing cover, and the side wall of the outer sealing cover and the side wall of the container mouth form a second sealing structure. According to the container mouth packaging structure, the container mouth is provided with the two sealing covers, the two sealing covers are provided with the two sealing structures, and therefore a container is more stable in sealing performance and more sanitary to use.

Description

technical field [0001] The invention relates to the packaging field of screw mouth containers, in particular to a container mouth packaging structure with two layers of sealing covers. Background technique [0002] In today's life, the use of containers in the fields of packaging, transportation and storage of articles is extremely common, especially the use of screw-mouth containers is very extensive. [0003] In the prior art, such a threaded mouth container is provided with threads at the mouth of the container, and then sealed by a sealing cap provided with threads. However, this sealing structure is only provided with a sealing structure on the top wall of the sealing cover and the upper end of the container mouth, and there is a gap between the threaded cooperation between the container opening and the sealing cover, which cannot realize the sealing of the container. The sealing structure can only be sealed by a sealing structure at the top wall of the sealing cover. ...
