Description

Combined metal cover for easy disassembly

The present invention is related to bottle caps, and more specifically, to a combined metal bottle cap that can be twisted and opened with bare hands. The bottle cap uses two kinds of metal parts, and the combination of the parts can be released by pulling a tear ring. relation.

A metal bottle cap that can be twisted and opened with bare hands is typically disclosed in CN208264901. It includes a bottle cap body made of metal, and a cushion block arranged on the top of the inner cavity of the bottle cap body. The inner circumferential wall surface of the bottle cap body is provided with an inner thread, and the outer circumferential wall surface of the bottle cap body is provided with an outer thread. Since both the inner thread and the outer thread are set as evenly distributed multi-thread threads, the metal bottle cap has the characteristics of a small capping angle, and at the same time, the sealing effect of the metal bottle cap has no influence.

Metal caps of this type do not provide vacuum identification and are therefore limited in scope.

The purpose of the present invention is to provide a combined metal bottle cap that can be twisted and opened by hand. The bottle cap uses two metal parts, aluminum and iron. The component realizes the vacuum identification of the top cover and the function of strengthening the sealing, and the combined relationship between the main body of the bottle cap and the top cover can be released by pulling a tearing ring, which is beneficial to metal sorting and recycling.

The present invention realizes the technical means of above-mentioned purpose effect:

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 hereby expressed. Various objects in the embodiments are drawn according to proportions, sizes, deformations or displacements suitable for description, rather than the proportions of actual elements, which will be described first. In the following description, identical and symmetrically arranged elements are denoted by the same reference numerals.

1 to 5 , the combined metal cap of the present invention mainly includes a bottle cap body 1 made of aluminum and a top cap 40 made of iron.

The bottle cap body 1 includes a tear ring 10 and an annular side wall 20 . The tear ring 10 includes an annular top portion 11 , a rounded corner portion 12 that is bent downward following the top portion 11 , and a connecting portion 13 that is formed downwardly following the rounded corner portion 12 . The top 11 of the tear ring 10 horizontally extends a pull tab 14 from a part of its inner circumference toward the center. Extending from one side of the pull tab 14 through the top 11 , the rounded portion 12 and the connecting portion 13 is a first slit 15 with a thinned thickness, extending from the other side of the pull tab 14 through the top 11 and the connecting portion 13 The rounded portion 12 is provided with a second slit 16 with a reduced thickness. The top portion 11 corresponding to the diameter of the center point of the pull-tab 14 extends to the rounded portion 12 with a third slit 17 having a reduced thickness. The annular side wall 20 extends vertically and continues below the connecting portion 13 , and a support edge 23 is formed at the junction of the annular side wall 20 and the connecting portion 13 and is formed on the support edge 23 . There is a weak part 22 on the top but the thickness of the structure is thinned. A safety ring 30 is connected with the bottom edge of the annular side wall 20 by several bridging points 31 that can be broken. The bottom of the safety ring 30 is bent inward to form a locking portion 32 .

The top cover 40 includes a disc-shaped cover plate 41, the center of the cover plate 41 is formed to be up and down The floating vacuum identification button 42, the peripheral edge of the cover plate 41 is bent downward to form a rounded part 43, the peripheral edge of the cover plate 41 and the inner surface of the rounded part 43 are combined with a soft and elastic sealing ring 44, the cover The bottom end of the rounded portion 43 of the plate 41 is bent inward to form a curling edge 45 , and the open end of the curling edge 45 is covered by the sealing ring 44 . The top cover 40 is assembled in the tear ring 10 , the circumferential top surface of the cover plate 41 is in contact with the inner surface of the top 11 of the tear ring 10 , and the vacuum identification button 42 is exposed on the top 11 of the tear ring 10 In the area enclosed by the frame, the rounded portion 12 of the tear ring 10 fits to receive the rounded portion 43 of the top cover 40 , and the supporting edge 23 supports the bottom of the rolled edge 45 of the top cover 40 .

As shown in FIG. 6 to FIG. 8 , the combined metal cap is encapsulated in a bottle mouth 50 , the top cover 40 closes the bottle mouth 50 , the sealing ring 44 tightly presses the top circumference of the bottle mouth 50 , and the bottle cap body 1. Covering the entire outside of the bottle mouth 50 , the annular side wall 20 rolls a concave hobbing 24 according to the bottle mouth thread 51 , and the safety ring 30 is located under the stopper portion 52 of the bottle mouth 50 . Due to the vacuum in the bottle, the vacuum identification button 42 sinks downward.

As shown in FIG. 9, the method of opening the combined metal cap to take out the contents of the bottle is to apply a twisting force to the bottle cap body 1, so that the bottle cap body 1 rotates up along the bottle mouth thread 51, but The locking portion 32 of the safety ring 30 is restricted under the stopper portion 52 of the bottle mouth 50 , and the safety ring 30 cannot move up with the bottle cap body 1 so as to reverse the rotation of the bottle cap body 1 . All the bridging points 31 are twisted off by the force, the safety ring 30 is separated from the annular side wall 20 , the safety ring 30 remains under the stop part 52 of the bottle mouth 50 , and the bottle cap body 1 is screwed upwards Open, the supporting edge 23 pushes the top cover 40 upward, releasing the sealing relationship between the top cover 40 and the bottle mouth 50, the vacuum identification button 42 is raised upward, and the top cover 40 follows the bottle cap body. 1 out of the bottle mouth 50.

As shown in FIG. 10 and FIG. 11 , as mentioned above, the bottle cap body 1 is made of aluminum, and the top cover 40 is made of iron, which should be disassembled and recycled when discarded. The pull tab 14 can be pulled upward with bare hands, and a tear is generated from the pull tab 14 The pulling force will tear the first crack 15, because the first crack 15 extends from one side of the pull tab 14 through the top 11, the rounded portion 12 and the connecting portion 13, so when the first crack 15 is torn The tear ring 10 will be broken after the tear; the pulling force generated by the pull tab 14 may also split the second tear 16, but because the second tear 16 extends from the other side of the pull tab 14 through the The top portion 11 and the rounded corner portion 12 , so the second crack 16 will not break the connecting portion 13 there. Therefore, the pull tab 14 will still remain on the tear ring 10 .

After the tearing ring 10 is disconnected from the first opening 15, the disconnected tearing ring 10 can be pulled outward by the pull tab 14, so that the third opening 17 is cracked; The force can break all or part of the weak part 22, so that the tear ring 10 is completely or partially separated from the annular side wall 20, in any case, the tear ring 10 can be released from the top cover 40, the top cover 40 and the bottle cap body 1 can be separated. Because the third crack 17 extends from the top 11 to the rounded portion 12 , after the third crack 17 is cracked, the connection portion 13 there will not be disconnected, but it will expand due to the tear ring 10 . However, it is bent, so the tearing ring 10 becomes an open ring, but it will not be broken into two pieces. According to this, the aluminum cap body 1hdr cjig jmyhv hapi
