Description

[Detailed description of the invention] [Field of industrial application] This invention stores a thin film-like synthetic resin container in a cardboard box, and only the spout tube of this container is placed in the box. This relates to a liquid container that protrudes outside the box from a box opening formed in the box, and is intended to prevent unauthorized opening of this type of container.

[Conventional technology]

A liquid container that houses a thin film-shaped synthetic resin container inside a cardboard box, with only the spout tube of this container protruding outside the box from the box opening formed in the box is commonly known as ""Bug in Box" or "Bottle in Box"
It is also called and used by other names such as ``Pet In Box''.

This above-mentioned container is extremely inexpensive;
For reasons such as ease of incineration, relatively robustness, small volume when empty, and extremely advantageous transportation of containers from the container manufacturer to the manufacturer of the liquid content, It has come to be used in large quantities in many different fields.

As described above, this type of container has many advantages, but since almost all of the synthetic resin container is located inside the cardboard box, the stored liquid is completely isolated from the outside of the box. That will happen.

This almost complete light blocking property has the advantage of protecting the liquid contents from light, but it also has the disadvantage that it is not possible to visually confirm whether the liquid contents are properly stored from outside the container. It is occurring.

In particular, there was concern that even if the container was illegally opened and the liquid content was extracted during the period from the producer to the consumer, the fraud would not be known.

In order to eliminate the above-mentioned concerns regarding this type of container, we have developed an assembly member that is immovably assembled to the spout tube to fix the spout tube of the container to the box opening of the box, and a spout formed by the spout tube. There is a device in which the container is integrally formed with a screw cap for opening and closing, and the container can be opened for the first time by cutting between the assembly member and the screw cap.

[Problem that the invention attempts to solve]

However, in the above-mentioned container, the assembly member and the screw cap must be molded as one piece, so the structure of the assembly member and the screw cap becomes complicated, which makes the molding difficult, and the assembly becomes difficult. It is not possible to distinguish between the attachment member and the screw cap at a glance, and it is difficult to tell by feel when the screw cap is rotated to open, or by applying external force to the member connecting the attachment member and the screw cap. The only way to know whether or not there is an unauthorized opening is to check whether or not the cap is illegitimately displaced, so it is troublesome to identify whether or not there is an unauthorized opening. Therefore, it was necessary to take some means to achieve sealing of the spout until the screw cap was assembled.

The cause of this problem in the prior art is that the assembly member is integrated with the screw cap, and that identification of the presence or absence of unauthorized opening is attempted to be achieved by cutting between the assembly member and the screw cap. be.

Therefore, in the present invention, the assembly member is configured as a separate object from the screw cap as before, and a part of this assembly member is separated when the screw cap is unsealed for the first time. This is a technical issue.

[Means for solving problems]

Hereinafter, the present invention will be described with reference to drawings showing embodiments of the present invention.

The means of the present invention is a liquid container in which a pouring spout tube 1 made of a thin film-shaped synthetic resin container is housed in a box 20 made of cardboard and protrudes outward from a box opening 21 of the box 20. There is a pipe provided around the outer circumferential surface of the spout pipe 1, and a box spout 2.
The spout tube 1 has a locking flange 5 that locks on the inner surface of the mouth edge of the spout tube 1; a flange 12 is provided around the outer periphery of the lower end of the cap 9 that screws and seals the spout tube 1; It has a pressing flange 16 that is assembled so that it cannot be pulled out upwardly and clamps the mouth edge of the box opening 21 between it and the locking flange 5, and
The present invention has the following features: a presser jig 14 configured by integrally installing a hook ring 17 that locks onto the flange piece 12 from above via a plurality of connection pieces 18 that are easy to break.

[Effect]

The spout tube 1 is sealed by the cap 9 immediately after the liquid is injected into the container, and the timing is independent of the assembly of the container into the box 20. That is, if the filling of the liquid into the container is performed before the container is assembled into the box 20, the container sealed with the cap 9 will be assembled into the box 20, and the liquid inside the container will be filled. When filling the container with the liquid content is performed after the container is assembled into the box 20, the cap 9 is assembled into the container that is already assembled into the box 20.

The container, that is, the spout tube 1, is assembled and fixed to the box 20 by assembling the presser jig 14 from above to the spout tube 1, which is sealed by the cap 9 and protrudes from the box opening 21.

That is, by assembling the holding jig 14 to the spout tube 1, the mouth edge of the box opening 21 is strongly clamped between the locking flange 5 and the pressing flange 16, and this clamping causes the pouring to be performed. The outlet tube 1 is immovably assembled and fixed to the box 20.

In addition, the hook ring 17 that is integrally provided with the presser jig 14 that is assembled and fixed to the spout tube 1 in such a manner that it cannot come out upwardly is attached to the cap that is screwed and assembled to the spout tube 1. Since the cap 9 is locked from above to the flange piece 12 of the cap 9, when the cap 9 is rotated in the unthreading direction and displaced upwardly relative to the spout tube 1, it is assembled to the spout tube 1 so that it cannot be displaced. The hook ring 17, which is integrally provided to the main body of the presser jig 14 via the connecting piece 18, moves upward together with the cap 9 against the connecting force of the connecting piece 18, and breaks the connecting piece 18. Separate from the presser jig 14. Therefore, by knowing whether or not the hooking ring 17 is connected to the holding jig 14 main body by the connecting piece 18,
It is possible to easily and accurately identify whether the container has already been opened or not.

In this way, since the cap 9 that seals the container and the holding jig 14 that immovably assembles and holds the spout tube 1 to the box 20 are separate objects, it is easy to assemble the container into the box 20. This sealing of the container can be achieved regardless of the time,
Therefore, there is no need to provide a functional part for independently sealing the spout in the spout tube 1, and the assembly limit positions of the cap 9 and the holding jig 14 to the spout tube 1 can be mutually controlled individually. Since the spout can be set without any pressure, it is possible to achieve reliable and good sealing of the spout by the cap 9, and also to prevent the spout tube 1 and the box 2 from being sealed by the holding jig 14.
A strong assembly and fixation with 0 can be achieved.

In addition, separation of the hook ring 17 from the main body of the holding jig 14 can be easily confirmed by lightly pulling up the hook ring 17 with a fingertip or by tilting the entire container greatly, so that unauthorized opening of the container can be prevented. The presence or absence can be easily and accurately known.

Furthermore, the box opening 21 is assembled to the spout tube 1.
The presser jig 14, which has a pressing flange 16 that presses the mouth edge of the container from above, covers the entire area of the box opening 21, so that the box opening 21 is not exposed as part of the external appearance of the container. The appearance can be improved.

〔Example〕

The cap 9 has a cylindrical shape with a top, and a thread 11 is carved on the inner circumferential surface of the circumferential cylinder 10 to be threaded into a thread 2 provided on the upper part of the outer circumferential surface of the spout tube 1.
A flange piece 12 is provided on the lower end of the outer circumferential surface of the circumferential tube 10 in a projecting manner.

Further, the presser jig 14 is configured with an assembled cylindrical piece 15 as a main body, which is attached to the spout tube 1 with a pressing flange 16 around it so that it cannot come off upwardly, and this assembled cylindrical piece 15 A hook ring 17 is integrally provided at the upper end of the hook via a connecting piece 18. Since the holding jig 14 is assembled to the spout tube 1 to which the cap 9 has been assembled, the inner diameter of the assembled tube piece 15 is larger than the outer diameter of the cap 9. For this reason, the presser jig 14, that is, the assembled cylinder piece 15 is assembled into the spout tube 1 so that it cannot come out upwards.
The part also has an outer diameter larger than the outer diameter of the cap 9, and a fitting cylinder piece 4 is provided hanging down from the outer peripheral edge of the flange 3 provided on the outer peripheral surface of the main body portion of the spout cylinder 1. Pour spout tube 1 of jig 14 holding piece 4
This is the assembly part. Since the fitting cylindrical piece 4 has a locking flange 5 at its lower end, the outer diameter of the fitting cylindrical piece 4 is equal to or slightly smaller than the diameter of the box opening 21.

In the case of FIGS. 2 and 3, a locking protrusion 19 is provided on the lower end of the inner circumferential surface of the assembled cylindrical piece 15, which has a pressing flange 16 protrudingly provided on the lower end of the outer circumferential surface.
This locking protrusion 19 rides over the locking protrusion 6 provided on the upper end of the outer peripheral surface of the fitting cylinder piece 4 and locks it from below, so that the holding jig 1
No. 4 is attached to the spout tube 1 so that it cannot be pulled out upwards.

In the case of the embodiments shown in FIGS. 4 and 5, the presser jig 14 is attached to the spout tube 1 in a manner that it cannot be removed upwardly by carving a mounting screw 7 on the outer circumferential surface of the fitting tube piece 4. , Rack teeth 8 with each tooth facing upward are carved in the portion directly below the outer peripheral surface of the fitting cylinder piece 4 provided with the mounting screw 7, and in contrast to the rack teeth 8, the inner peripheral surface of the assembled cylinder piece 15 is carved. An assembly screw 19a that screws into the mounting screw 7 is carved, and the assembly cylinder piece 15 is screwed into the fitting cylinder piece 4 to the limit on the lower end surface of the assembly cylinder piece 15 located directly above the rack teeth 8. When assembled, the rack teeth 8 are provided with several locking teeth 19b that lock in the direction of unscrewing the mounting screw 7 and the set screw 19a. The locking makes it impossible for the presser jig 14 to rotate in the unscrewing direction with respect to the spout tube 1, thereby making it impossible for the presser jig 14 to escape upwardly from the spout tube 1.

In the figure, reference numeral 13 is a gasket for more completely sealing the spout tube 1 with the cap 9.

[Effect of idea]

As is clear from the above description, the present invention is capable of firmly achieving and maintaining the assembly of the container into the box, and also prevents unauthorized opening of the container by simply knowing the condition of the hook ring located in an easily observed location. can be easily and accurately identified, the structure of each component can be simplified, and there are no restrictions on their mutual combination, making manufacturing, assembly, and handling easy. It exhibits many excellent effects, such as a better appearance and the ability to firmly and stably seal the spout with the cap, both before and after the first opening.
