Description

Coupling device with multiple threads

The present invention relates to a coupling device having multiple threads that can be coupled to different container necks through a single coupling device having multiple threads even if the specifications of the threads formed on the container neck are different.

As the prior art, the inventors of the present invention have described the technologies of PCT / KR2008 / 4210 and PCT / KR2011 / 08735 and PCT / KR2013 / 8127.

In the case of PCT / KR2008 / 4210, which is the conventional technology, for example, a bottle cap is formed inside the bottle cap to be coupled to a container neck having a thread size of 26.78 MM and 28 MM, and the bottle cap of the structure having the plurality of threads. Silver, with a single bottle cap, the first thread group for joining to an approximate thread of size slightly smaller or smaller than 26.78MM and 26.78MM, and the thread size of the container neck slightly larger than 28MM and 28MM In order to reasonably form a second thread group to be coupled to an approximate thread of a small size or a small size, a thread having a different shape of a thread is formed on the cylindrical inner wall of the bottle cap.

However, the above-described technique is applicable to all container necks having a thread of 25.4MM to 30MM standard, which is generally distributed and practically used by a group of the first screw thread and the second screw thread formed on the single wall surface of the bottle cap, that is, the inner wall of the side part. It was virtually impossible to engage and seal through one bottle cap with a plurality of threads.

Therefore, in order to be combined with all the groups of container trees, it was necessary to form a thread on the inner wall of the multi-stage stage instead of a single inner wall, in which case, the size of the bottle cap becomes large enough to impede the practical use, or to the factory automation. It caused a lot of difficulties.

Notwithstanding the above, when the second screw thread is formed on the bottle cap so as to be caught by the thread of the container neck having the 30MM thread specification at the bottom of the first screw group designed to be caught by the 28MM container neck thread, When the group was to be joined to a container neck with a thread size of 28 mm, there was a closed end where the second thread group was resisted by the skirt of the attached bottle cap at the bottom of the 28 mm thread of the container neck.

Of course, the skirt and the like attached to the neck of the container may be removed, but this is practically impossible in consideration of the convenience of the consumer, the PCT / KR2008 / 4210 is applied to the neck of the container having a thread of the standard 25.4MM to 30MM standard Firearms have had problems and have been operated to engage with container necks with 25.4 to 28 mm threads.

However, the market still had container heads with 30MM threads, and PCT / KR2011 / 08735 was developed to meet the needs of these markets.

The PCT / KR2011 / 08735 is a technology that can combine and seal the container neck having a thread of 25.4MM to 30MM standard with one bottle cap.

However, as a problem, there are many technical difficulties in sealing through the inner diameter of the container neck because of the difference in the inner diameter of the container tree, and if the technical difficulty is easily solved, the closing price of the manufacturing price increases.

In the case of PCT / KR2013 / 8127, in particular, referring to FIG. 55, the lower coupling part is designed to be caught by a thread of 30MM container neck by placing a lower coupling part on the lower side, but the lower coupling part is a skirt or neck formed on a conventional container neck. Engaged in the support ring to interfere with the coupling, as shown in Figure 72 has a prefabricated coupling load side coupling portion as a soft material of different physical properties, but this also hit the skirt or screw thread or neck support ring to interfere with the coupling.

In addition, in the case of having a hook-type elastic coupling space as shown in Figure 59, the elastic coupling space was not separated after passing through the neck support ring, the bottle cap was not possible to separate from the container neck.
