And a fastening member 17 for fitting and fixing to the spout of the bag. This fitting and fixing is performed by screwing the male screw 2-1 of the F-type outlet neck and the female screw 17-1 of the fastening member 17. When the pipe-shaped member is rotated by the lever 15-2, the cock is opened and closed corresponding to the rotation position, and the liquid is poured out and stopped.
A claw 15-1 is integrally provided on the lever portion 15-2 of the pipe-shaped member 15. The claw 15-1 is fitted to the claw receiving portion provided on the cock body 16, and the lever 15-2 is used until it is used. The rotation of is locked. At the time of use, the claw 15-1 is folded to be rotatable.
[0004]
As shown in Fig. 7, the T-type spout type bag is fitted with a cock closure 18 with a score 18-2 that has a virgin function to maintain a sealed state at the time of shipment, and further, dust on the head. A cap 21 is attached to prevent entry. In use, the dust cap 21 is removed, a dedicated cock cap 21 in which the cock opener 26-2 is integrated is used, and the cock cap 21 is attached to the cock closure 18. The cock cap 21 for the T-type outlet 3 includes a cock body 26 in which a cock nozzle 26-1 and a cock opener 26-2 are integrated, and a cock 25 with an opening / closing knob. The cock body 26 is a cock closure. The female screw 18-1 cut inside 18 and the male screw 26-3 cut outside the cock body 26 are screwed together. At that time, the score 18-2 provided at the bottom of the cock closure 18 is pierced and opened by the cock opener 26-2.
[0005]
As described above, as the cap member, there are many parts such as different cock caps for F-type outlet and T-type outlet, sealing caps and dust caps used at the time of shipment, and cock closures. It was. In addition, when the cock cap is attached, the cock lever or cock nozzle that has a protruding shape is subjected to excessive force due to contact with other members, and the deformation causes a gap between the members, causing liquid leakage or contact with outside air. Caused the inconvenience that would occur.
[0006]
[Problems to be solved by the invention]
Therefore, the present invention realizes a cock cap that does not cause liquid leakage or contact with outside air even if the cock lever or cock nozzle having a protruding shape receives excessive force due to contact with other members and deforms. By providing a cock cap that can be used for both F-type outlet and T-type outlet, and can be shipped even with the cock cap attached from the beginning. It saves labor, reduces the number of necessary parts, and attempts to increase production efficiency through single-product, multi-product production.
[0007]
[Means for Solving the Problems]
The shape of the cock lever is substantially L-shaped so that the long arm of the lever comes into contact with the lid surface, and the cylindrical step on the side of the cock body, not the side of the cock that rotates the nozzle It is provided integrally so as to extend through. In addition, the neck of the cock-closure that is fitted and combined with the T-type spout is shaped like a male screw similar to the neck of the F-type spout, and for the T-type spout, a cock opener is attached to the annular part of the cock body. By interpolating, the score of the cock closure can be released.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
By making the shape of the cock lever substantially L-shaped, the long arm part of the lever comes into contact with the lid surface part, absorbs stress at the contact surface, and prevents the cock part from being deformed. Because the nozzle part is provided on the cock body side instead of the rotating cock member side, the cock body itself remains deformed even when stress is applied, and there is a gap between the cock part integral with the lever and the cock body. It does not occur.
Also, the neck of the cock closure that is fitted and combined with the T-type spout is shaped like a male screw similar to the neck of the F-type spout, and the F-type spout and the T-type are fitted by a female-cap shaped cock cap on the cock body side. It can be attached to both outlets, and when used for a T-type outlet, the cock closure score can be opened by inserting a cock opener in the annular part of the cock body. .
[0009]
[Example 1]
Figure 1, as shown in FIG. 2, cook cap 1 of the present invention, a pipe-like member (5) which substantially L-shaped lever 5-1 at one end is formed integrally (material polystyrene), the bag cock body member 6 fitting holding portion are integrated structure to the annular portion 6-4 to spout mate with rotatably fitted and held the pipe-shaped member 5 (material low density polyethylene) The fastening ring member 7 (material is high-density polyethylene or low-density polyethylene) for fitting and fixing the annular portion 6-4 to the spout of the bag. In this respect, it is the same as the cock cap for the conventional F-type outlet shown in FIG. 6, but a cylindrical step portion 6-2 is provided on the cock body side to extend the nozzle portion 6-1. The difference is that the shape of the lever 5-1 is substantially L-shaped and the long arm portion 5-11 is in contact with the lid surface portion 6-4 of the cock body 6 at the rotation stop position. To do. Then, a short pipe-like pipe-shaped member 5 having no nozzle portion, that is, a lever 5-1 and an integrally structured cock portion 5-2 is inserted and fitted into the fitting holding portion having a larger central inner diameter of the cock body 6. The hole 5-3 of the pipe-like member coincides with the hole 6-3 on the cock body side at a certain position by the rotation of the lever 5-1, and the bag-side spout 2 is connected via the annular portion 6-4. The liquid is poured out from the nozzle portion 6-1 through the communication. The cock body 6 has an air hole 6-5 corresponding to the stop position of the lever so that when the liquid is stopped, the air is removed and the liquid does not remain in the pipe-shaped member 5 and the nozzle portion 6-1. Is provided. As shown in FIG. 1, the cock cap according to the present invention is attached to the F-type spout 2 in the same manner as in the past, and the fastening ring member with the male and female threads cut at the neck of the F-type spout is cut. 7 and screwing.
[0010]
Since the present invention is formed not on the pipe-shaped member 5 to which the nozzle portion 6-1 is fitted, but on the side of the cock body 6 to be fitted, the external force is applied to the protruding nozzle portion 6-1. However, the deformation remains in the deformation of the cock body 6 itself, and no gap is generated between the pipe-shaped member 5 and the cock body member 6. Therefore, it is possible to prevent the beverage from being oxidized or contaminated with bacteria due to leakage or contact with the outside air. Further, as apparent from FIG. 2B, the lever shape is substantially L-shaped, and the long arm portion 5-11 is in contact with the lid surface portion 6-6 of the cock body 6 at the rotation stop position. Therefore, the external force to the lever 5-1 that is also a protruding shape is received by the wide lid surface portion 6-6, so that a gap is generated between the pipe-like member 5 and the cock body member 6 even if an excessive force is applied. There is nothing wrong. Therefore, even in this portion, it is possible to prevent contamination of bacteria due to liquid leakage and contact with outside air.
[0011]
[Example 2]
3 and 4 show an example in which the cock cap according to the present invention is used for a T-type outlet type bag. The structure of the cock cap portion constituted by the pipe-shaped member 5, the cock body member 6 and the fastening ring member 7 is exactly the same as that for the F-type spout shown in FIGS. However, it is different in that the cock closure 8 (the material is LLD polyethylene or low density polyethylene) is fitted into the T-type outlet and the liquid is sealed more thoroughly by the score 8-1 having a virgin function. In the neck portion 8-2 of the cock closure 8 used in the present invention, a male screw 8-2 having the same standard as the male screw cut in the neck portion 2-1 of the F-type outlet 2 is cut. The cock opener 9 (material polystyrene) cockling than combined outer fitting 10 to the indicated F-type spout 2 in the cock body annular portion 6 4 of the same cock cap 1 for mounting in FIG. 1 (Materials Is made of polypropylene or high-density polyethylene). Further, in order to ensure the fitting between the cock cap 1 and the cock opener 9, as shown in FIG. 4, a saw-toothed convex portion 9-1 is provided on the peripheral surface of the neck portion of the cock opener 9, and the flexibility of the material is utilized. Thus, it is possible to adopt a configuration in which it engages with the annular portion 6-4 of the cock body 6. As with the F-type spout 2, the T-type spout 3 is attached by screwing between the male thread 8-2 cut at the neck of the cock closure 8 and the fastening ring member 7 at which the female thread 7-1 is cut. The score 8-1 provided at the bottom of the cock closure 8 is pierced and opened by the cock opener 9 in the process of performing screwing.

【The invention's effect】
In the present invention, since the nozzle portion is formed on the cock body side as described above, even if an external force is applied to the protruding nozzle portion, the deformation remains in the deformation of the cock body itself, and the pipe member and the cock body member There is no gap between them. In addition, since the lever shape is substantially L-shaped, and the long arm portion is in contact with the lid surface portion of the pipe-like member at the rotation stop position, the external force to the lever which is also a protruding shape is a wide lid surface Therefore, there is no possibility that an excessive force is applied between the pipe-shaped member and the cock body member to form a gap.
Further, the T-type spout is provided with a F-type spout by screwing with a fastening ring member with a female thread by interposing a cock closure with a male thread similar to that of the F-type spout at the neck. By simply attaching a cock opener as an adapter to the cock cap used for the spout, the same can be used together, and the same cap can be used at the time of shipment, greatly reducing the number of corresponding components. can do. In some cases, the use of the cap at the time of shipment is omitted, and even if the cock cap used at the time of wearing is shipped from the beginning, it is possible to prevent liquid leakage due to the force applied to the protruding portions such as the nozzle and the lever. In addition, there are various effects such that it is not necessary to provide a claw and a claw receiving member for preventing the opening of the cock as conventionally provided in the cock cap for the F-type outlet.
