Hereinafter, the most preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. .

1 is a perspective view of a shoulder cap coupling structure according to the present invention, Figure 2 is a cross-sectional view of the shoulder cap coupling structure according to the present invention, Figure 3 is to remove the contents leak-proof sealing portion of the shoulder cap coupling structure according to the present invention 4 is a perspective view of the spout after removing the contents leakage preventing sealing portion of the spout according to the present invention, Figures 5a and 5b is a re-storage after removing the contents leakage preventing sealing portion of the spout according to the present invention To illustrate the state in which the spout cap is closed, it will be described together for convenience.

As shown, the shoulder cap coupling structure 1 according to the present invention, as in the prior art, and the spout 20 is integrally bonded to the adhesive surface 24 to the pouch container or refill container 50 of the plastic material and The spout cap 10 is largely coupled to seal the spout 20.

That is, the spout cap 10 includes a cap main body 11 having a lower opening, a first threaded portion 13 formed in an inner wall of the cap main body 11 in a circumferential direction, and the cap main body 11. It consists of an annular rim (12) formed at the open bottom of the expansion.

In addition, the outer circumferential surface of the side wall of the cap main body 11 is formed with a latch-shaped unevenness (not shown in the figure) for preventing slipping when held by a hand during the opening operation.

In addition, an annular sealing portion removing means 14 in which a plurality of insertion grooves 14-1 are formed at a predetermined distance from each other is formed around the edge of the circular upper end of the cap body 11. Content leakage by preventing the leakage of the contents of the spout 20 to be described later by the annular sealing portion removal means 14, the plurality of spinning projections 32 of the sealing portion 30 is inserted into the insertion groove 14-1 and rotated. Preventing sealing unit 30 can be removed by removing from the spout 20.

The spout 20 has a joining surface 24 fixed in the joining portion of the pouch container or the refill container 50 and a discharge passage 21-1 for discharging the contents to the upper portion of the bonding surface 24. A spout shoulder 21, a second threaded portion 23 formed on an outer circumferential surface of the spout shoulder 21 and fastened to the first threaded portion 13 of the spout cap 10, and the discharge passage 21-1. The spout shoulder 21 is made of a content leakage preventing sealing part 30 which is detachably fixed to the top of the spout shoulder 21 so as to seal the entire upper portion thereof.

Here, the adhesive surface 24 of the spout 20 is integrally bonded to the pouch container or refill container 50 in which the contents are accommodated through a conventional thermal fusion method.

On the other hand, the contents leak-proof sealing portion 30 is separably fixed to the upper end of the spout shoulder 21, the circular plate 31 for sealing (sealing) the entire upper portion of the discharge passage (21-1), and The outer circumference of the circular plate 31 is composed of a plurality of radial projections 32 are formed spaced apart in a radial direction.

As such, the discharge passage 21-1 in the spout shoulder 21 that may be generated in the course of transportation of the product by forming the contents leakage preventing sealing part 30 formed of the circular plate 31 and the plurality of spinning protrusions 32. It is possible to prevent leakage of the contents and leakage through the source.

In addition, when purchasing and using a product made of a shoulder cap coupling structure according to the present invention, when the spout cap 10 coupled to the outer periphery of the spout 20 is turned in a predetermined direction, the inner peripheral surface of the cap body 11 The spout cap 10 is separated from the spout 20 by raising the first threaded portion (female threaded portion) 13 formed in the upper portion along the second threaded portion (male threaded portion) 23 of the spout shoulder 21.

At this time, the separated spout cap 10 is turned upside down, and a plurality of insertion grooves 14-1 formed in the annular sealing portion removing means 14 of the cap main body 11 prevent leakage of the contents of the spout 20 ( By rotating the spout cap 10 after inserting the plurality of spinning projections 32 of 30, the contents leakage preventing sealing portion 30 that is weakly coupled to the spout 20 by its rotational force is separated and removed to discharge the discharge passage ( 21-1) is fully open so that the user can drink the contents.

On the other hand, the outer periphery of the lower spout shoulder 21 is formed with an annular protrusion 22 protruding outwardly thereof and an inclined jaw portion 22-1 extending to the lower portion of the spout shoulder 21 to form a spout by the spout cap 10 ( When the spout cap 10 coupled to the outer periphery of the spout 20 is turned in the closing direction during the complete closing of the 20, the first threaded portion (female threaded portion) 13 formed on the inner circumferential surface of the cap body 11. ) Is lowered along the second threaded portion (male screw portion) 23 of the spout shoulder 21, and the inner circumference of the annular rim 12 formed on the open lower end of the cap body 11 is annular projection 22 ) And the inclined jaw portion 22-1 is completely closed at the same time as the locking.

In addition, after removing the contents leak-proof sealing portion 30 of the spout according to the present invention is to close the spout cap 10 for restorage, in this case, the contents through the contents discharge passage of the open spout outside Can leak.

In this case, as illustrated in FIGS. 5A and 5B, an inner leakage upper end portion of the cap 10 having an open upper end corresponding to an inner upper outer outer side or an outer upper inner inner end of the shoulder 20 may have a leakage preventing annular rib ( Rib (15a) (15b) is further formed to prevent leakage even when re-storage.

That is, even after the spout cap 10 is closed after the contents of the spout leakage sealing portion 30 are removed, the leakage preventing annular ribs 15a and 15b which protrude downward are formed on the inner outer outer top or outer outer inner upper end. By being in contact with the spout, the contents can be prevented from flowing out or leaking through the contents discharge passage.

Here, in the case of the leak-proof annular rib 15a shown in FIG. 5A, the spout cap 10 and the shoulder cap 20 are formed even if they are formed relatively short on the inner circumferential outer upper end of the shoulder 20. Even though the contents are leak-tightened by the screw fastening, even if the sealing portion 30 is removed, when the screw is closed by the fastening, it is possible to completely contact. Of course, before the contents leak-proof sealing portion 30 of the spout is removed, the leak-proof annular rib 15a is seated in the center groove 33 on the upper surface of the content leak-proof sealing portion 30. In this way, the center groove 33 to which the leakage preventing annular rib 15a can be seated is formed on the contents leakage preventing sealing portion 30, so that the spout cap 10 is rotated in the direction of closing the initial assembly. It is possible to prevent the contents leakage preventing sealing portion 30 in contact with the annular rib (15a) is pressed by the downward pressure input to crush to one side to be damaged.

On the other hand, in the case of the other leakage preventing annular rib (rib) 15b shown in Figure 5b is formed relatively longer than that of Figure 5a in the upper end of the outer periphery of the shoulder 20, not a screwing method It can be preferably used when the spout cap 10 and the shoulder cap 20 by the forced indentation method by the undercut. That is, a gap (gab) is generated as the upper and lower spaces of the leakage preventing sealing part 30 to be removed at the time of coupling by the undercut, so that leakage is prevented for a long time to compensate for the space outside the contents leakage preventing sealing part 30. Since the annular rib 15b is formed, even if the contents leakage preventing sealing portion 30 is removed, the leakage space can be completely contacted by the undercut while compensating for the loss space.

Here, reference numerals 40 and 60, which are not described, are self-sealing valves and self-sealing valve retaining rings as self-sealing valve means, and such self-sealing valve means are optional in the present invention, and are described in more detail in FIGS. 6A to 6C described below. Let's explain.

6A is a perspective view showing the structure of the self-sealing valve of the spout according to the present invention, and FIGS. 6B and 6C are schematic plan views and vertical cross-sectional views showing the operating states of the self-sealing valve of the spout according to the present invention, respectively.

The above self-sealing valve means (not shown in the figure) is used for opening and sealing an opening (not shown in the figure) at the point where the discharge passage 21-1 of the pouch container or the refill container 50 starts. A sealing valve 40 and a magnetic sealing valve fixing ring 60 for fixing and holding the magnetic sealing valve 40 to the inner circumference of the annular projection 22 under the spout shoulder 21.

The substantially disc-shaped self-sealing valve 40 is to be opened and sealed in accordance with the internal pressure change of the flexible pouch container or refill container 50 in the center of the discharge of the pouch container or refill container 50 Opening self-sealing part 41 for opening and sealing the opening (not shown in figure) of the starting point of the passage 21-1, and the recessed part formed surrounding the said self-sealing part 41 (Fig. No. And a flexible insertion protrusion 42 having no grant). Here, the material of the self-sealing valve 40 is preferably silicone rubber with excellent flexibility, but the present invention does not limit the material.

In addition, the self-sealing valve fixing ring 60 has a central opening (not shown in the drawing number) in which the opening self-sealing portion 41 is inserted in the center, and the magnetic sealing valve is inserted in the upper end of the central opening. A projection 42 is inserted to form an insertion protrusion seating portion 61 which is press-fitted and seated by an upper press-fitting surface 22-3 on the inner circumference of the annular protrusion 22. In addition, an annular protrusion 62 is formed by being inserted into an annular groove 22-2 formed at the inner circumference of the inclined jaw portion 22-1, which extends to the lower portion of the annular protrusion 22 and is expanded.

The operating state of the self-sealing valve of the shoulder cap coupling structure according to the present invention having such a structure will be described in more detail.

As shown, the self-sealing valve 40, as described above, when pressed to press the pouch container or the refill container 50 of the flexible material during use, the contents, that is, the fluid solution is ejected while the compression force When removed, the valve is automatically sealed.

Self-sealing portion 41 has a case opening and closing groove (41-1), such as '×' type, '+', '-' type, 'Y' type, such opening and closing groove (41-1) is sealed In close contact with each other, the sealing effect is exhibited. For convenience of description, referring to FIG. 5B in which a vertical cross-sectional view of the self-sealing valve 41 is shown, the '×' type opening and closing groove 41-1 in a state in which no pressure is received from the inside of the pouch container or the refill container 50 is shown. ) Is kept in close contact with each other.

On the other hand, referring to Figure 5c of the unopened state, when the pressure from the pouch container or refill container 50 is opened and opened while opening and closing groove (41-1) is lifted to the left. That is, some of the magnetic sealing portion 41 and the flexible insertion protrusion 42, which are dynamic portions of the self-sealing valve 40, change shape during operation, while the inner periphery and the inclined jaw portion of the annular protrusion 22, which is the static portion, The annular groove 22-1 or the like of 22-1 maintains its original state. This opening phenomenon is more likely to occur when the self-sealing valve 40 (including the magnetic seal 41) is made of a relatively flexible material such as silicone rubber.

Here, it is preferable to use a silicone rubber having excellent flexibility as the material of the self-sealing valve 40, but such a polyethylene / polypropylene blend, it is made of a material having a relatively low flexibility, but having a shape retention (rigidity, etc.) As a matter of course, the material of the present invention is not limited so long as it has a certain degree of flexibility.

As such, the self-sealing valve 40 may not only allow the quantitative discharging of the contents, but may also fall sideways due to the characteristics of the pouch container 50 even when the spout cap 10 and the contents leak-proof sealing part 30 are separated and opened. In this case, it is possible to prevent the contents from coming out.
