However, according to this device, when a projection or the like hits on the head of the valve member (a) when not in use during transportation or the like, the valve rod (b) slides and the valve opens, causing liquid leakage or contact with outside air. There was a problem.

Therefore, a method has been adopted in which the spout is sealed with a cap so as not to cause a leakage accident even when an external force is applied when not in use, and the spout is removed and a cock member is attached when used in use. By the way, the bag filled with aseptic beverage liquid at the factory has a liquid injection outlet member attached as an integral structure by welding or the like, a cock cap is attached to the spout, and the cock of the cock cap is opened and closed to open and close the liquid. Operates dispensing and stopping. The F-type type is a simple type in which the liquid inlet / outlet member is simply an opening. When used, the cap is removed to release the sealed state, and is replaced with a cock cap with a cock for use in supplying the liquid. Things. In the T type, a cock closure is fitted into the opening of the liquid injection outlet member so that the sealed state is maintained until use.
At the time of use, remove the dust cap, attach a cock cap with a cock opener, release the score inside the spout without external force, and break the sealed state,
It is used for beverages. The spout, the cock cap, the cock closure, the cap, and other members are made of plastic having appropriate flexibility. FIGS. 6 (simple type F-type spout) and FIG. 7 (T-type spout via a cock-closure having a high sealing effect) specifically show a liquid injecting / outlet member of this type of conventional bag-in-box. ), But the cock cap used at the time of use has a different structure. Incidentally, the F-type spout has a male screw 2-1 cut at the neck, and a sealing cap 20 with a female screw 20-1 cut therein is fitted at the time of shipment to ensure sealing. When using the sealing cap 20
A cock cap 11 is used instead of the cock cap 11. The cock cap 11 is fitted with a pipe-shaped member (cock nozzle) 15 having a nozzle at one end and a lever at the other end, and a spout of a bag. Annular part 16-1 and pipe-shaped member 15
And a fastening member 17 for fitting and fixing the annular portion 16-1 to the spout of the bag. ing. This fitting is fixed by the male screw 2-1 at the neck of the F-type spout and the fastening member.
It is made by screwing with 17 female screws 17-1. lever
When the pipe-shaped member is rotated according to 15-2, the cock is opened and closed according to the rotation position, and the liquid is poured and stopped. The lever 15-2 of the pipe-shaped member 15 is integrally provided with a claw 15-1. The claw 15-1 is fitted with a claw receiving portion provided on the cock body 16, and the lever 15-2 is used until it is used. Is locked. At the time of use, the claw 15-1 is folded to be rotatable.

As shown in FIG. 7, a T-type spout type bag is fitted with a cock closure 18 having a score 18-2 having a virgin function for maintaining a sealed state at the time of shipment, and furthermore, a head portion. A cap 21 for preventing the ingress of dust is attached. At the time of use, the dust cap 21 is removed, and a dedicated cock cap 21 having a cock opener 26-2 as an integral structure is used. The cock cap 21 is attached to the cock closure 18. The cock cap 21 for the T-type spout 3 comprises 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 above-mentioned cock opener 26-2
As a result, the score 18-2 provided at the bottom of the cock closure 18 is pierced and opened.

As described above, as the cap member, F
A large number of parts had to be prepared, such as different cock caps for the mold spout and T-type spout, sealing caps and dust caps used at the time of shipment, and cock closures. In addition, when the cock cap is fitted, the protruding cock lever or cock nozzle receives excessive force due to contact with other members and deforms, creating a gap between the members, causing liquid leakage or contact with outside air. Has been inconvenient.

[0006]

Therefore, according to the present invention, a cock lever or cock nozzle having a protruding shape receives an excessive force due to contact with another member and is deformed by the deformation.
By realizing a cock cap that does not cause liquid leakage or contact with the outside air, oxidation and contamination of the beverage can be prevented, and in some cases, shipping can be performed even with the cock cap attached from the beginning, and F-type injection The purpose of the present invention is to provide a cock cap that can be used for both the outlet and the T-shaped spout to save labor, reduce the required number of parts, and increase production efficiency through single-product, multi-production.

[0007]

Means for Solving the Problems The cock lever has a substantially L-shape so that the long arm of the lever abuts on the surface of the lid. It is provided integrally on the cock body side so as to extend through a cylindrical step. Also, the neck of the cock-closure to be fitted and combined with the T-type spout has the same male screw shape as the neck of the F-type spout, and a cock opener is provided on the annular portion of the cock body for the T-type spout. The interpolation allows the score of the cock closure to be released.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION By making the shape of a cock lever substantially L-shaped, the long arm of the lever comes into contact with the lid surface to absorb the stress at the contact surface and deform the cock. In addition to preventing the occurrence of the above, the nozzle portion is provided not on the rotating cock member side but on the cock body side, so that even if stress is applied, the deformation of the cock body itself remains,
The purpose is to prevent a gap from being formed between the cock body and the cock part integrated with the lever. Further, the neck of the cock closure fitted and combined with the T-type spout has the same male screw shape as the neck of the F-type spout, and the F-type spout and the T-type are provided by a female screw-shaped cock cap on the cock body side. So that both outlets can be used
When used for a mold spout, a cock opener is inserted into the annular portion of the cock body so that the score of the cock closure can be opened.

[0009]

Embodiment 1 As shown in FIGS. 1 and 2, a cock cap 1 of the present invention has a pipe-like member 5 (material) having an approximately L-shaped lever 5-1 integrally formed at one end. Is a polystyrene), a cock body member 6 (material) in which an annular portion 6-4 that fits into the spout of the bag and a member 6-2 that rotatably fits and holds the pipe-shaped member 5 are formed. Is a low-density polyethylene) and a fastening ring member 7 (made of high-density polyethylene or low-density polyethylene) for fitting and fixing the annular portion 6-4 to the spout of the bag. I have.
In that respect, it is the same as the conventional cock cap for the F-type spout shown in FIG. 6, except that a cylindrical stepped portion 6-2 is provided on the cock body side to extend and form the nozzle portion 6-1. And that the long arm 5-11 contacts the lid surface 6-4 of the cock body 6 at the rotation stop position when the shape of the lever 5-1 is substantially L-shaped. I do. Then, a short pipe-shaped member 5 having no nozzle portion, ie, a lever 5-, is provided in the fitting holding portion 6-2 having a larger central inner diameter of the cock body 6.
As a configuration in which the cock 5-2 having an integral structure with the hole 1 is inserted and fitted, the hole 5-3 of the pipe-shaped member coincides with the hole 6-3 on the cock body side at a certain position by the rotation of the lever 5-1. To the spout 2 on the bag side via the ring 6-4.
More liquid is being dispensed. The cock body 6 has an air hole 6-5 corresponding to the stop position of the lever so that the air does not escape and the liquid does not remain in the pipe-shaped member 5 and the nozzle portion 6-1 when the discharge of the liquid is stopped. 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 prior art, with a male and female threaded fastening ring member cut at the neck of the F-type spout. 7 by screwing.

In the present invention, since the nozzle portion 6-1 is formed not on the pipe-shaped member 5 to be fitted but on the cock body 6 side to be fitted, the protruding nozzle portion 6-1 is formed.
Even if an external force is applied to 1, the deformation is limited to the deformation of the cock body 6 itself, and there is no gap between the pipe-shaped member 5 and the cock body member 6. Accordingly, it is possible to prevent the beverage from being oxidized or contaminated with various bacteria due to leakage or contact with the outside air.
In addition, as is 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. So
The external force to the lever 5-1 which is also a protruding shape is received by the wide lid surface 6-6, and a gap is created between the pipe-shaped member 5 and the cock body member 6 even if excessive force is applied. There is no. Therefore, also in this portion, contamination of various bacteria due to liquid leakage and contact with outside air can be prevented.

[0011]

Embodiment 2 FIGS. 3 and 4 show an example in which a cock cap according to the present invention is used for a T-type spout 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. The difference is that a cock closure 8 (made of LLD polyethylene or low-density polyethylene) is inserted into the T-type spout, and the liquid seal is made more thorough by a score 8-1 with a virgin function. The neck 8-2 of the cock closure 8 used in the present invention is formed with a male screw 8-2 of the same standard as the male screw cut into the neck 2-1 of the F-type spout 2. And the F-type spout 2 shown in FIG.
A cock opener 9 (made of polystyrene) is fitted into a ring 6-5 of a cock body that is the same as the cock cap 1 attached to the hopper, and is fastened and held by a cock ring 10 (made of polypropylene or high-density polyethylene) from the outside. It has such a configuration. Further, in order to ensure the fitting between the cock cap 1 and the cock opener 9, a serrated convex portion 9-1 is provided on the neck peripheral surface of the cock opener 9 as shown in FIG. Ring part of cock body 6
It can be configured to engage with 4. The attachment to the T-type spout 3 is performed in the same manner as the F-type spout 2 by screwing the male screw 8-2 cut at the neck of the cock closure 8 and the fastening ring member 7 cut at the female screw 7-1. 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 screwing.

[0012]

According to 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 is limited to the deformation of the cock body itself, and the pipe-shaped member is not deformed. There is no gap between the body and the cock body member. In addition, since the lever shape is substantially L-shaped and its long arm portion comes into contact with the lid surface portion of the pipe-shaped member at the rotation stop position, the external force to the lever, which is also a protruding shape, is large on the lid surface. There is no possibility that a gap is generated due to excessive force applied between the pipe-shaped member and the cock body member. In addition, the T-type spout is provided with a male-threaded cock closure at the neck similar to the F-type spout, so that the F-type spout is screwed with the female-threaded fastening ring member. The same thing can be used by simply attaching a cock opener as an adapter to the cock cap used for the spout, and the same cap can be used at the time of shipment, greatly reducing the number of corresponding components can do. In some cases, even if the use of the cap is omitted at the time of shipment and the cock cap used at the time of use is worn from the beginning, the liquid can be prevented from leaking due to the force applied to the protrusions such as the nozzle and the lever. In addition, there are various effects such as the necessity of providing a claw for preventing opening of the cock and a claw receiving member, which are conventionally provided in the cock cap for the F-type spout, and the like.
