Description

Bottle caps joined to different container necks

The present invention relates to the coupling of the bottle cap to the container neck of different specifications without a separate connection, the prior art had a closed end that requires a separate connection when the dimensions of the container neck is different.

The container neck accommodates a bottle cap, and the bottle cap received safely stores the contents in the container and exists for opening and closing the contents.

However, according to the diversification of the industry, the preference of the consumer and the size of the conventional container neck are changing a lot. For example, the international standard 28mm container neck is now too subdivided, and the shape of the thread is also 1 It is different according to the thread of thread to 5 thread of thread.

In recent years, various container necks, such as 26.78 mm or 26.2 mm or 26.0 mm, which are similar to 28 mm, have been put to practical use. The main reason is that the weight of the container is reduced and the weight of the corresponding bottle cap is reduced.

Food and beverage companies that handle various kinds of container necks do not have any problems because they use the appropriate bottle caps, but in terms of those who operate against empty containers already distributed and used, various container necks cause a lot of burden.

In other words, if you put the extract or powder, etc. in the bottle cap and individually packaged bottle caps containing these heterogeneous substances, in the measure of operating, the bottle caps need to be prepared to fit the neck of various types of containers, and a lot of costs are incurred. In addition, consumers have a lack of discrimination, there is a possibility that can be used only after reading the instruction manual in detail.

In order to overcome this end, the present inventor has proposed a technology that can be coupled to different container necks through one bottle cap as shown in Figures 5 to 7, the present invention has an object to the improvement of such technology will be.

As a description of the prior art, in the case of Figure 5 is shown a typical 28MM container neck, container neck A (200A of container neck thread A (200SA) of the conventional screw thread 100 of the conventional bottle cap 100 ( There was no problem in that 100A) was caught because the conventional first screw thread A (100A) was formed at the lower end portion.

6 shows a container neck B (200B) of 26.78 MM. In the case of the above, the container thread B (200SB) is formed with a sufficient gap so that the conventional second thread B (100SB-) is shown. There was no problem with 1) getting caught in the container neck thread B (200SB).

However, as shown in FIG. 7, in the case of having a container neck C (200C) of 26.2MM, the gap between the container neck thread C (200SC) is not sufficient, and thus the dimension is different depending on the conditions for injection molding the conventional bottle cap 100. After that, it was difficult for the conventional second screw thread C (100SC-1) to catch the container screw thread C (200SC).

Accordingly, the present invention has an object to achieve the realization of bottle caps that can be coupled to different container necks within close tolerances through one bottle cap under any adverse conditions.

As one method, a plurality of threads in the inner wall of the inner side of the inner coupling portion of the main body to provide a container of the outer diameter of the container neck within an error range of less than 3MM, and a bottle cap that can be combined with the bottle neck as a single bottle cap And a plurality of the threads are based on a bottle cap coupled to a different container neck having a first screw thread formed on the lower part and a second screw thread formed on the upper part so that the plurality of threads can be coupled according to the thread shape of the container neck. I am doing it.

The thread height of the point where the first screw thread ends is set to about 3.63 mm in a developed view on the basis of the point where the first screw thread starts, and the first screw thread achieves the purpose by the rotation of the screw within 360 degrees. I would like to.

In addition, the starting reference point of the second screw thread is about 3.73MM as the starting reference point of the first screw thread, the second screw thread is a three-line thread standard having different starting positions, and the second screw thread has a different starting position. It is composed of a middle thread, the starting reference point of the second second screw thread having a different starting position is around 4.22MM based on the start of the first screw thread.

The inner side of the coupling side wall portion is about 9.15MM, and the second screw thread has a three-threaded thread in equal parts, but the second screw thread formed on the inner side wall portion of the coupling portion has only two lines. The inner diameter of 26.0MM, and the inner diameter of the second screw thread is about 25.5MM to achieve the purpose.

If the neck of the container is different, you need to prepare bottle caps for each dimension, but the present invention can be solved as a bottle cap, the opportunity cost is reduced, where it is possible to manage only one bottle cap cost This saving effect is also provided, and since the lid is formed to be coupled without removing the skirt attached to the neck of the container, the convenience that the consumer can use without removing the skirt is added.

1 is a longitudinal cross-sectional view of the bottle cap of the present invention.
Figure 2, according to Figure 1, showing a state in which the engaging side portion inner wall portion unfolded on the development view arbitrarily.
3 and 4 is a cross-sectional view illustrating that the bottle cap of the present invention can be applied in various states.
Fig. 5 is a reference view, which is a longitudinal sectional view showing a state in which a bottle cap is fastened to a commonly used 28MM container neck, FIG. 6 is a bottle cap fastened to a 26.78MM container neck, and FIG. 7 is 26.2MM The bottle cap is attached to the container neck.

The inner side of the main body 10 for providing the container neck in which the outside diameter of the container neck is within an error range of 3 mm and the bottle cap 1 that can be combined with the bottle cap 1 in the container neck ( 11) A plurality of threads are formed in the inner side wall portion 12 for engagement, which is the inner side, and the plurality of threads are provided with a first thread 13 on the lower side so that the plurality of threads can be engaged according to the thread shape of the container neck. The side part constitutes the bottle cap 1 coupled to another container neck having the size of the second screw thread 14 formed therein.

The thread height H-2 at the point where the first screw thread ends is based on the point where the first screw thread 13 starts is about 3.63 mm in the developed view.

In addition, the first screw thread 13 is preferably a rotation of the screw within 360 degrees, but in some cases more than that is possible.

In addition, the starting reference point of the second screw thread 14 is about 3.73 mm as the starting reference point of the first screw thread 13.

The second screw thread 14 is a three-threaded thread specification different from each other in the starting position, the second screw thread 14 is composed of triple threads having different starting positions, and the second second thread having different starting positions It is preferable that the starting reference point of the thread 14B is about 4.22MM as the starting reference of the first screw thread 13.

In addition, the height of the coupling side wall portion 12 (that is, the length) is preferably about 9.15MM, and the size of the second screw thread 14 is equal to three rows of threads, but the coupling side wall inner portion 12 The formed second screw thread 14 may be formed of only two lines.

The inner diameter of the first screw thread 13 is about 26.0 mm, and the inner diameter of the second screw thread 14 is about 25.5 mm.

Further explanation based on FIG. 2 to help understanding is as follows.

The surface of the coupling side portion inner wall portion 12 may be deformed such that a predetermined portion does not become a surface but protrudes or sinks, and the first screw thread 13 shown in the developed view is the first screw thread A 13A shown in detail. ), The first screw thread B (13B), the first screw thread C (13C), etc., but may be expressed in any arbitrary form, the size and thickness of the thread can be freely expressed.

The second screw thread 14 is also represented by the second screw thread A to D (14A, 14B, 14C, 14, D), but this can also be modified, except that the starting position of the second screw thread A (14A) is first. Experimental results showed that screw fastening was about 3.73 mm from the starting reference point of thread A (13A).

It can be seen that the sign (H-1), which is the starting height of the second screw thread A (14A), is located on the same height line as the sign (H-2), which is the height of the portion where the first screw thread (C) ends. (See Figure 2).

In addition, it can be seen that the sign indication (H-3), which is the start height of the second screw thread B 14B, is also started in a state of invading any one portion of the first screw thread 13.

The reason for the above is described with reference to FIG. 7, which is a conventional technique. When the conventional second screw thread C (100SC-1) is vulnerable to the container neck screw thread C (200SC), the conventional bottle cap 100 is fastened to the container neck. There was a closed end where the thread was not easily caught. Therefore, in the present invention, the second screw thread A 14A and the second screw thread B 14B are provided as close as possible to the area of the first screw thread 13 to achieve the object. This goal is overcome by trial and error over a year.

This result, similar to 28MM container neck, proved that the bottle cap 1 was very firmly coupled to the two-threaded container neck, and as a result, the container neck of about 25.9MM and the approximate value of 26.2MM It has been combined with one bottle cap (1) in more than 90% of the container necks, except for 30.0MM, including 26.78MM and 28MM container necks. The design of mass production molds already on order for practical use demonstrates the improved technology of the present invention.

The bottle cap (1) technique described above is particularly suitable for an accommodating device containing a heterogeneous material, because the heterogeneous material receiving device is suitable for an aftermarket rather than a non-foam market, but is in the market, especially in the United States. Drinking water (bottled water) in circulation has a container size of about 25.9 MM / 26.2 MM / 26.78 MM / 28 MM 1 row screw / 28 MM 2 row screw / 28 MM 3 row screw / 38.0 MM It is virtually impossible to make a suitable device for heterogeneous materials, and many companies give up because they are too expensive and use stick packing which is generally used.

However, stick packaging cuts one side of the bag, opens the bag, opens the bottle cap, and in the process of pouring powder into the bottle, causing consumer inconvenience, and the root consumption is being lowered.

Therefore, the present invention put the vitamins, etc. in the bottle cap (1) The bottle cap (1) is capable of combining with any other container neck of the standard to have a safe and convenient mixing and drinking of heterogeneous material will be.

According to the present invention based on this idea, referring to FIG. 1, there is a folding portion F, and below the folding portion F, a receiving portion 15 having a storage space 16 is provided. Heterogeneous substances such as vitamins are put into the storage space 16 and the lower portion thereof is sealed with the sealing surface 17.

And in the use of the above, buy drinking water on the market, remove the bottle cap is closed, it combines the bottle cap 1 of the invention and then press the folding portion (F) folding portion (F) The lower cutout 18 destroys the sealing surface 17 and simultaneously drops and mixes the contents of the storage space 16 into the container.

In another embodiment, as shown in Figure 3 illustrates that the bottle cap (1) can be realized in various modifications, by assembling the cover 19 on the top it is possible that the shape of the entire bottle cap (1) can be transformed into a cup form. It is showing.

In addition, such a bottle cap (1) is not limited to this can be modified into a variety of heterogeneous material receiving device, which is an additional means, this invention is to provide only the bottle cap (1) technology that can be coupled to a different container neck, but 4 is further described as follows.

In FIG. 4, the sealing surface is divided by the perforation line 21, and the receiving part 20 having the storage space 16 is assembled into the main body 10. In use, the folding part F is pressed. When the cutout 18 breaks the cutout line 21, at the same time, the heterogeneous material falling into the storage space 16 falls.

After purchasing a widely distributed 25-26.2mm or 26.78mm or 28mm beverage or mineral water, remove the common lid and use the lid of the present invention in combination, if there is a dissimilar substance, touch a separate stopper at the top Then, the heterogeneous material inside the lid is mixed with the contents inside the container to create a new type of beverage.
