Description

Bottle cap with accommodating cavity

The present invention is related to bottle caps, and more specifically, is a bottle cap with a containing cavity.

Plastic bottles or glass bottles are general-purpose containers for all kinds of drinks and liquid medicines. The container has a narrow mouth and uses a bottle cap as a safety seal. Based on the requirements of mixing additives for liquid medicines or adding flavoring agents to beverages, when powdery, liquid, or gel-like additives or flavoring agents are added to the container through a narrow bottle mouth, the problem of leakage to the outside of the bottle mouth often occurs. To solve this problem, first, the user needs to pour the drink in the container into a wide-mouthed container, and then add flavors or additives to the wide-mouthed container. However, the disadvantage is that the added flavors or additives are very likely to be incorrectly estimated. Quasi-problem.

In order to solve the above-mentioned problems, the present invention proposes a bottle cap with an accommodating cavity.

The technical features and effects of the present invention:

A bottle cap with a accommodating cavity, the bottle cap being installed on a bottle mouth of a container; the bottle cap comprising: a lower cap and an upper cap screwed on the lower cap; the lower cap is enclosed in the bottle Mouth; the lower cover contains a knife, the upper cover has a accommodating cavity and a film that closes the accommodating cavity; the film is opposite to the cutting knife; the accommodating cavity has liquid and solid contents; rotating the upper cover to make It moves down according to the thread, and the cutter cuts through the film to form a breach, and the content is released into the container through the breach. After the film is cut by the cutter until it loses its tight tension, it hangs downwards without detaching from the upper cover, so as to prevent the film from falling into the container.

The accommodating cavity stores a certain amount of content, so that the amount of flavors or additives added to the container is appropriately estimated, and the problem of excessive amounts will not occur.

In order to facilitate the description of the central idea of the present invention expressed in the column of the above-mentioned summary of the invention, specific embodiments are used to express it. The various objects in the embodiment are drawn according to the proportion, size, deformation or displacement suitable for explanation, rather than drawn according to the proportion of the actual element, which will be described first.

As shown in Figures 1 to 4, the bottle cap of the present invention includes: a bottom cap 10 and an upper cap 20.

The lower cover 10 includes an annular top 11, the outer circumference of the annular top 11 is downwardly formed with a first ring wall 12, the bottom end of the first ring wall 12 is formed with a first safety ring 13, the first safety The ring 13 and the first ring wall 12 are connected by a number of breakable first bridging points 132; the inner wall surface of the ring top 11 is provided with an inner leak-proof ring 111 and an outer leak-proof ring 112, the first The inner wall surface of the ring wall 12 is provided with a first thread 121; The inner wall surface of the first safety ring 13 is provided with a plurality of first locking portions 131; the inner circumference of the ring top 11 is formed with a second ring wall 14 upward, and the outer wall of the second ring wall 14 is provided with a first Two threads 141; the second ring wall 14 is formed with a plurality of horizontally surrounding stop ribs 142 under the second thread 141; the second ring wall 14 extends downward to form a third ring wall 15. The inner wall of the bottom end of the third ring wall 15 is formed with a horizontal connecting portion 16 inwardly, and the connecting portion 16 is formed with an upwardly extending cutting knife 17 having a longitudinal blade 171 with cutting force. The intersection of the top end of the cutter 17 and the longitudinal blade 171 forms an upwardly protruding spike 172.

The upper cover 20 includes a closed cover 21. The outer circumference of the cover 21 is downwardly formed with a fourth ring wall 22. The inner wall of the fourth ring wall 22 is provided with a third thread 221. The fourth ring wall A second safety ring 23 is formed at the bottom end of the second safety ring 23. The second safety ring 23 and the fourth ring wall 22 are connected by a plurality of breakable second bridging points 232; the inner wall of the second safety ring 23 is provided with There are a number of second locking portions 231; the outer ring of the second safety ring 23 is formed outward to form a tearing initiation portion 233; the inner wall of the cover 21 extends downward to form a tube body 24, the tube body The bottom end of 24 extends beyond the second safety ring 23, and the bottom end of the tube body 24 is closed by a film 25 in a tight tension state; the film 25 can be plastic or aluminum foil; the film 25, the tube body 24, And the cover 21 defines an accommodating cavity 26 in which a quantitative solid or liquid content 27 is stored.

By known capping equipment and methods, the upper cap 20 is coupled to the second thread 141 of the lower cap 10 with the third thread 221, and the upper cap 20 is surrounded and coupled with the fourth ring wall 22 and the second safety ring 23 Outside the second ring wall 14 of the lower cover 10, the second locking portion 231 is located below the stop rib 142, the cover top 21 and the top end of the second ring wall 14 have a distance D1; the tube body 24 extends into the second ring wall 14 and the third ring wall 15, and the circumference of the film 25 is located on the cutter 17. When the second safety ring 23 is not removed, the upper cover 20 cannot be rotated.

As shown in Figures 4 and 5, the lower cap 10 is coupled to the external thread 31 of the bottle opening 30 of a container 35 by the first thread 121 by the known capping equipment and method, so that the first ring wall 12 surrounds the coupling At the bottle mouth 30, the first locking portion 131 and the first safety ring 13 are located under the annular convex eaves 32 of the bottle mouth 30. The inner leak-proof ring 111 closely contacts the top edge of the bottle mouth 30, the outer leak-proof ring 112 closely contacts the top edge corners of the bottle mouth 30, and the third ring wall 15 extends along the inner wall of the bottle mouth 30. Into the bottle mouth 30, the bottle mouth 30 is sealed by the lower cap 10.

As shown in Figures 1, 6, and 7, the second safety ring 23 is pulled outwards by applying a pulling force on the tear initiation portion 233, tearing all the second bridging points 232, the second safety ring 23 and the first The four ring walls 22 are completely separated. Rotate the upper cover 20, guided by the second thread 141 and the third thread 221, the upper cover 20 moves downward until the film 25 is pierced by the spike 172 of the cutter 17, and then continue to rotate the The upper cover 20, the film 25 rotates with the upper cover 20 and is circularly cut the film 25 along the circumference by the longitudinal blade 171 of the cutter 17, until the film 25 completely loses its tension and hangs downward. It is difficult for the cutter 17 to cut the film 25 again, and the content 27 of the accommodating cavity 26 is released into the interior of the container 35; shake the container 35 to make the content 27 and the liquid in the container 35 fully mix uniformly.

As shown in the eighth figure, when the mixed liquid in the container 35 is taken, the lower cap 10 can be rotated, and the lower cap 10 can be rotated upward through the guidance of the external thread 31 and the first thread 121 of the bottle mouth 30. Since the first locking portion 131 is blocked by the annular eaves 32, the first safety ring 13 cannot move upward with the lower cover 10, so the rotational torque of the lower cover 10 acts on the first bridging point 132 , So that it is all screwed off, the first safety ring 13 is separated from the lower cover 10 but is kept under the annular raised eaves 32, the lower cover 10 can be opened along the external thread 31 of the bottle mouth 30. Leave the bottle mouth 30.

The second example of the bottle cap of the present invention is described in the ninth figure. The difference from the first example described in the first to eighth figures is only that there is no first safety ring, so the second example of the bottle cap passes the known sealing After the cap equipment and technology are encapsulated in the bottle mouth 30, the entire bottle cap and the bottle mouth need to be covered with a sealing film (not shown in the figure) using a conventional technology to achieve the purpose of preventing opening.
