Description

A bottle cap having a coupling portion coupled to a plurality of container necks, the method of forming the coupling portion

The present invention relates to a lid for use in combination with a container neck that can be coupled through a single lid to a container neck of different thread specifications.

As a prior art, as the inventor of this invention, there existed the technique of PCT / KR2008 / 4210, PCT / KR2011 / 08735, and PCT / KR2013 / 07107.

In the case of the prior art PCT / KR2008 / 4210, for example, the bottle cap is formed in the inside of the bottle cap to be coupled to the container neck having a thread size of 26.78MM and 28MM, the bottle cap of the structure having a 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 used in a single neck of the bottle cap, i.e., a plurality of threads in a container neck having a screw thread of 25.4MM to 30MM size, which is generally distributed and practically used only by the group of the first screw thread and the second screw thread formed on the inner wall of the side part. It was virtually impossible to join and seal through a single bottle cap with a thread of.

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 container neck 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.

PCT / KR2008 / 4210 was developed in 2007, completed in 2008, and successfully commercialized in the United States in 2013.

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.

PCT / KR2013 / 07107 has solved such a conventional sealing problem and all the problems to be coupled to a single bottle cap in several container necks.

In particular, the present invention is the same technology as the present invention in the configuration with the technology of PCT / KR2013 / 07107, but the present invention has been described in order to clarify an example of its use more realistically, specifically, 25.4MM to 30MM Couplings and seals are formed to combine and seal a container neck having a thread in a standard, or a different approximation, or a container neck having a thread of various specifications with a single bottle cap.

In particular, in forming the joint, the joint was easily molded in the process of injection molding, and also easily taken out from the mold, the priority applied in the PCT / KR2013 / 07107 application for the purpose of achieving the same purpose in the present invention It is intended to achieve that purpose.

The lid used for joining a container neck of different sizes, such as a container neck thread, a skirting frame, or an inner diameter of a ring frame or an inner wall of the container neck, has various forms such as an inner receiving portion of the lid or a shape protruding outward. Heterogeneous materials, such as liquids or powders, are incorporated, and the above-mentioned lid is coupled to the container neck, or the above-mentioned lid is coupled to the container neck, and then touched or opened other parts such as the cap or the upper cap formed on the upper part of the lid. The heterogeneous material contained in the container's container may be dropped and mixed into the container, or the liquid containing the fragrance or taste in the container's container may be discharged through the container. The contents are melted and released.

And the lid has a long side extends to the lower side, the inner side of the side portion has a side inner wall portion, the side portion inner wall portion or the side portion inner wall portion in the direction of the elastic coupling that maintains a certain angle toward the upper body of the upper side of the side portion Form wealth.

In addition, the side portion or the upper body portion with the coupling portion is formed of one or more open space, the shape and size are freely selected.

And the coupling portion is to be fixed to any one or more of the coupling protrusion formed on the end of the coupling portion or the surface of the coupling portion, such as the container neck thread, skirting frame, or ring frame.

For example, the coupling part may be caught only at any specific part such as a container neck thread or a ring frame, alternatively, it may be caught at any part, and in order to be caught at any part, a plurality of coupling part protrusions formed on the surface of the coupling part may be used. It will be formed.

According to one aspect, a bottle cap having a main body coupled to the center of the container neck of the container formed with a container neck thread or skirting frame, or a ring frame, and the body side portion and the side inner wall portion of the bottle cap in the foreign exchange portion of the container neck A coupling part having a coupling part protrusion is fixed to any part, such as a protruding or recessed form formed in the formed.

And the coupling part projection is to have a coupling portion coupled to a plurality of container neck to be elastically hooked to any part of the container neck is coupled to the body of the bottle cap.

In addition, a portion or the upper portion of the side portion having the coupling portion is formed with a space of the open form.

According to yet another aspect, in the various bottle caps, the lid has a long side portion extending downward, the inner side of the side portion has a side wall portion, the side portion inner wall portion or the bottom of the side portion is bonded or bonded to the soft coupling portion Form an elastic bond.

In addition, the soft bonding portion is in the form of a film, and the bonding portion is a stretchable film such as nylon is added thereto.

According to yet another aspect, a lid used for coupling to a container neck having a container neck of different sizes, such as a container neck screw thread or a skirting frame, or an inner diameter of a ring frame or an inner wall of the container neck, may be connected to the inner receiving portion or the outside of the lid. The heterogeneous material such as liquid or powder is incorporated into the receiving part in various forms such as a protruding shape, and the upper cap formed on the main body of the lid or other upper part after the lid is coupled to the container neck or the lid is coupled to the container neck. In the process of touching or opening other parts of the lid, heterogeneous substances contained in the container's container are dropped and mixed into the container, or a liquid containing fragrance or flavor in the container's container is contained in the container. Various types of lids are basically constructed, such that the contents contained in the accommodating part are melted and released in the process of being released through the accommodating part.

And the lower part of the main body of the lid and the bottle cap constituting a coupling that can be coupled to the neck, the main body has a plurality of support, the lower end of the support is connected by the elastic piece connecting portion.

In addition, between the support portion is to form an elastic piece having a plurality of engaging projections on the inner surface, it is possible to add a shrink film or the like to the outside of the main body if necessary.

And the elastic piece with the engaging projection is preferably inclined at an angle to the inside.

Even if the size of the container neck is inconsistent, it constitutes a coupling part for controlling different standards, so it is possible to combine and seal the container neck of various specifications with one bottle cap without having to separately provide bottle caps of various specifications. .

In addition, since the space above the coupling portion, there is an advantage that it is easier to mold and eject the coupling portion.

An embodiment of the present invention will be described with reference to the drawings.

First, with reference to FIG. 15, a definition of a preferred container to be applied to the present invention will be made. As shown in the drawing, the container shows the narrowest container 1000 and the largest container 1000C. For example, although the illustrated container 1000 is of a type having a container thread thread 1002 of 26.2 mm or less, the shape may be slightly different depending on the characteristics of the manufacturer.

Therefore, the container neck 1001 has a short height H starting at the ring frame 1005, and the inner diameter D1 of the container neck 1001 constituting the container neck inner wall portion 1003 is also narrow.

The outer diameter D2 of the container neck thread 1002 is also considerably smaller than the outer diameter D2C of the container neck thread 1002C having a large standard.

In addition, the container neck 1001A of the container 1000A, which is generally referred to as 26.78MM, has a difference in size and shape from the container neck thread 1002A. In particular, the height H1 is different from that of the small container 1000. It's a big difference.

And the container 1000B having the 28MM container neck thread 1002B has an inner diameter D1B similar to 26.2MM or 26.78MM, but also different in height H2.

In addition, the container 1000C having a relatively large size of the container neck thread (1002C) is referred to as 30MM, and the inner diameter (D1C) or the outer diameter (D2C) of the container neck (1001C) is a small cylinder (1000, 1000A, 1000B). Significantly larger than).

The container (1000, 1000A, 1000B, 1000C) having the technical configuration as described above is very diverse, such as one row, two rows, or three rows of container neck thread (1002, 1002A, 1002B, 1002C), in particular from 26.2MM to 26.78 MM containers (1000, 1000A) is the mainstream of three rows of container threads (10002, 1002A), and if the container neck threads (1002B) is 28MM, the thread is one row, or two rows, some three have.

In the case of having a 30MM container neck thread 1002C, almost three rows of threads are used, and a container having an approximation of 30MM may be smaller than three rows, or there are many container neck threads such as seven rows.

Based on this idea,

Container neck thread (1002,1002A, 1002B, 1002C) or skirting frame (1004,1004A,

1004B, 1004C) or Hwante (1005, 1005A, 1005B, 1005C) or the inner wall of the container (1003,

Inner diameter (D1, D1A, D1B, D1C) of 1003A, 1003B, 1003C) or other outer diameters (D2, D2A, D2B,

D2C), etc., different heights (H, H1, H2, H3) of the container wood (1001, 1001A, 1001B,

Lid 1, which is used for bonding to 1001C), has a heterogeneous material such as liquid or powder embedded in the container in various forms such as the inner container of the lid 1 or a shape protruding to the outside. 1 Note)

And after coupling the lid (1) to the container neck, or after coupling the lid (1) to the container neck to touch or open other parts, such as the body 100 of the lid (1) or other upper cap formed thereon The heterogeneous substance contained in the container 1 of the lid 1 may be dropped and mixed into the container, or the liquid containing the fragrance or taste of the solid content contained in the container 1 of the lid 1 may be in the container. (In FIG. 1, the pipe part 106 corresponds to the receiving part), the contents of the receiving part are melted and discharged in the process of being discharged through the capping part 106.

In addition, the lid 1 has a side portion 101 which extends downwardly, and has a side portion inner wall portion 103 inside the side portion 101, and is connected to the side portion inner wall portion 103 by a connecting portion 105. The elastic coupling portion 104 is maintained at an angle to the top.

Inner direction of the main body 100 having the engaging portion 104, the container (1000, 1000A,

In forming the sealing part (primary sealing part 107 and the upper part of the pipe part 109) which are sealed in close contact with the container neck

inner wall part

1003, 1003A, 1003B or the container neck upper end of 1000B, the said sealing part is Closed in close contact with the inner wall of the container (1003, 1003A, 1003B), that is, the primary sealing portion 107 of the narrow form (outer diameter) compared to the upper secondary sealing portion 108 of the upper form of the form The tube portion 106 is formed in the foreign exchange portion.

In addition, the upper end of the pipe portion 106 has a stage such as an upper end portion 109 in the form of a pipe, and a secondary sealing portion 108 having a larger standard (outer diameter) in a form that is further extended above and outside the end binary portion. It is formed.

In addition, the primary sealing part 107 is formed in a plurality of wings in the foreign exchange portion of the pipe portion 106 extending to the bottom, or the upper end of the pipe portion 109 is formed in the upper end of the pipe portion 106 is the upper end of the container neck It is configured to maintain the sealing force in contact with the.

And the secondary sealing portion 108 is the outer diameter or inner diameter of the container neck of the container applied to the lid 1 of the present invention, that is, the upper inner wall of the upper end of the container neck of the container 1000C, that is, the container neck The inner wall portion 1003C is in contact with or in close contact with the sealing unit is configured.

In addition, the secondary sealing portion 108 is to form a secondary sealing portion insertion groove 110 so that the upper end of the container neck of the large container neck 1001C is inserted and sealed.

And one or more engaging portions 104 in any position of the side inner wall portion 103 of the lid 1 is formed in one or a plurality of quantities integrally or separately separated, the engaging portion 104 is upward To maintain a constant angle toward, the length of the coupling portion 104 is the same or the length of the coupling portion 104 may be configured irregularly.

In addition, the end portion or the surface portion of the coupling portion 104 is formed with one or more wedge-shaped coupling portion projections 104A (see FIG. 4).

In addition, the coupling portion 104 is regularly positioned or different from the side portion inner wall portion 103, or the predetermined length of the coupling portion 104 positioned at a predetermined angle to the same.

In addition, the end of the coupling portion 104 is rounded or configured to maintain a constant angle, or the coupling portion 104 can be formed in one or more stages in the vertical direction on the side wall portion 103.

And the coupling portion 104 can be assembled to the side portion inner wall portion 103 of the side portion 101 prefabricated.

Such a lid 1 of the present invention will be described in more detail with reference to the drawings.

1 shows that the lid 1 is expressed in a longitudinal section in a form in which a portion is cut, and the lower end of the side portion 101 of the lid 1 is slightly open to the outside.

However, such a shape is not fixed, and a design change is easy as needed.

In addition, the coupling part 104 may have a height (length) freely set based on the main body upper part 102 on the side part inner wall part 103, and the primary sealing part ( 107) is to be sealed in a group whose container threaded thread size is less than 28MM.

The reason for this is the inner wall of the container neck (1003,1003A, 28MM, 26.78MM, 26.2MM, etc.).

This is because the inner diameters (D1, D1A, D1B) of 1003B) are virtually the same with slight differences, except that the outer diameters (D2, D2A, D2B) or height (H, H1, H2) and threads are slightly different in size.

Therefore, the container

inner wall portion

1003, 1003A,

1003B) is in perfect contact with it to maintain the sealing force.

And the bottle cap 1 makes the storage space 112 in the interior of the pipe portion 106, the upper portion of the pipe portion 106 has a folding portion (F) that can be folded downward, the folding portion When pressing (F), the dissimilar substance in the storage space 112 is released from the container while the open portion 111 at the bottom of the fold portion F destroys the bottom sealing portion 113 blocking the bottom of the pipe portion 106. Will be dropped into the mix.

In addition, the mixed contents may be discharged after the bottle cap 1 is removed from the container or discharged through a discharge hole formed by lifting the discharge table 200 located above the fold portion F.

The shape of the accommodating part and the storage space accommodating the heterogeneous material in the lid 1 may be variously changed in design. For reference, the primary sealing part 107 is assembled to the pipe part 106 after being manufactured separately. Or, the pipe unit 106 together with the primary sealing unit 107 may be coupled to the inside of the main body 100 after being manufactured separately.

In addition, the main body 100 may be applied in various forms such as a pump dispenser for discharging the contents of the container instead of the storage space 112 for receiving heterogeneous material, a stopper of a hinge type, or another universal push-pull stopper.

In addition, the primary sealing unit 107 and the secondary sealing unit 108, by inserting or double-injecting a synthetic sponge sealing member of the soft sponge at the bottom of the foreign exchange portion and the upper body portion 102 of the pipe portion 106 You can take on that role.

Subsequently, the side portion 101 or the main body upper surface portion 102 in which the coupling portion 104 is formed is an open space S.

FIG. 2 shows that the container neck sealing part of the multi-stage container is formed in the foreign exchange part of the pipe part 106, and the above-mentioned bottle cap 1 is coupled to the container 1000. As shown in FIG.

In addition, the upper side of the coupling portion 104 also has a perforated space (S), the space (S) is formed by the number of the coupling portion 104 or more.

Incidentally, the discharge zone 200 'is expressed to show that it is possible to apply a variety of, as shown, is not related to the spirit of the present invention.

3 shows an example in which the space S is formed in the main body 100 in which the main body integrated cover 114 is integrated on the upper part of the main body 100.

In the case of Figure 4, the engaging portion 104 is that the engaging projections 104A formed on the surface of the engaging portion 104 is fixed to any one or more, such as annulus (1005,1005A, 1005B, 1005C), Even in the case, the upper surface portion 102 of the body is formed with a space (S) of the upper portion of the coupling portion 104.

In addition, the length of the coupling part 104 may be freely extended or shortened as shown by a dotted line in FIG. 4.

In addition, as shown in the right side of FIG. 4, the coupling part 104 may extend upward and be connected to the main body upper surface part 102, in which case the extended coupling part 104 may be thin.

In the case of FIG. 5, the coupling part 104 of the main body 100 is coupled to the container 1000 having a narrow standard, and as illustrated, the coupling part protrusion 104A is attached to the annulus 1005. The primary sealing part 107 which is fixed and fixed to the foreign exchange part of the pipe part 106 is in close contact with the container neck inner wall part 1003 in the inner part of the skirt catching frame 1004 and is sealed.

And the upper part of the pipe 109 serves to prevent the body 100 is lowered more than a predetermined, the secondary sealing portion 108 is formed in the foreign exchange on the basis of the pipe top portion 109.

6 shows an example in which the engaging projection 104A of the engaging portion 104 is coupled to another container 1001A, and as shown, the engaging projection 104A is a circular frame 1005A. ) Is fixed.

In some cases, the engaging projection 104A may be caught by the skirt catching frame 1004A, but almost all of the

containers

1000, 1000A, 1000B, and 1000C remain with the skirt of the remaining bottle cap. This is not desirable.

That is, the skirt catching frame of the bottle cap remaining after the end is also used for the skirt catching frame 1004A shown in FIG. 6, so that the engaging protrusion 104A is fixed to the ring frame 1005A.

In addition, as shown in Figure 6, the primary sealing portion 107 formed in the foreign exchange portion of the pipe portion 106 is in close contact with the container neck inner wall portion 1003A is tightly sealed.

7 shows an example in which the main body 100 is coupled to a container 1000B of another standard, in which case, the engaging protrusion 104A is fixed to the annulus 1005B and the tubular portion 106 The primary sealing part 107 formed in the foreign exchange part is in close contact with the container neck inner wall part 1003B and sealed.

8 shows an example in which the main body 100 is coupled to another container 1000C of another standard, and as shown, the engaging protrusion 104A is fixed to the annulus 1005C. .

In addition, the coupling part 104 having the coupling part protrusion 104A can be seen that the side part inner wall part 103 is severely moved. This is why the container neck 1001C and the container neck inner wall part 1003C are moved. This is because it is larger than other containers.

Therefore, if the side portion 101 direction is also partially opened, it may be applied to a larger container (as long as it is large in approximation).

In addition, the secondary sealing portion 108 is in contact with the upper container neck inner wall portion 1003C of the container neck 1001C to maintain the sealing force.

In the case of Fig. 9, the height of the side portion 101 (symbol "H") of the main body 100 is shortened so that the engaging projection 104A of the engaging portion 104 is the container neck 1001 of the container 1000. It is shown that it is fixed to the container neck screw thread 1002 formed in the part.

Also in this case, the upper portion of the coupling part 104 is formed with a space S having an open shape, and in the case of the container 1000 having a narrow standard, the primary sealing part 107 formed in the foreign exchange part of the pipe part 106. ) Is in close contact with the container neck inner wall portion (1003).

And when the size of the container is large, the pipe portion 106 'formed at the upper end is in close contact with the inner wall of the container and sealed, and preferably, the elastic and soft secondary sealing portion formed in the foreign exchange portion of the pipe portion 106' ( 108 is preferably in close contact with the inner wall of the container neck.

In the case of Figure 10, the main body 100 has a plurality of elastic resilient piece 117, the lower end of the elastic piece 117 is connected by the elastic piece connecting portion 118.

And the inner wall portion of the elastic piece 117 is formed with a plurality of engaging projections (119).

In addition, as shown in dashed lines in FIG. 11, the curved elastic portion 120 may be provided. For this reason, when the coupling protrusion 119 receives severe resistance to a container neck thread or a ring of the container, the elastic piece 117 ) To make it back.

However, because each of the elastic pieces 117 are separated in each other in the form of a split so that some extent of the expansion in the rear without any problem, the engaging projection 119 is set and intended part such as container neck thread or ring frame It can be hung and fixed.

In the case of FIG. 12, it has shown that the part with coupling part 104 is opened into space S. In FIG.

Therefore, the space S may be freely formed in the space (S) such as the upper side or the side of the side portion (101).

The reason why the space S is formed is to secure a space for the coupling portion 104 to move, and also to allow the coupling portion 104 to be easily taken out of the mold during the injection molding of the coupling portion 104. to be.

FIG. 13 is an enlarged cross-sectional view of the main portion of FIG. 12, and shows that the space S is formed in a form where the coupling portion 104 is open.

And the lower end of the coupling portion 104 is a good way to extend from the side load end 101 '.

Illustrating one use method of the same, as shown in FIG. 14, it can be seen that the coupling part 104 is fixed to the container neck thread 1002C ′ of the container 1000C ′, in this case, in FIG. 13. The bottleneck closed portion 121 shown in contact with the upper foreign exchange portion of the container 1000C 'is sealed.

Subsequently,
