Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a liquid ejection container.

"Problems to be Solved by Conventional Techniques and Inventions" As a liquid ejection container, a container body and a cylinder are inserted into the container body, and a liquid ejection head is projected from the mouth neck portion of the container body and attached to the container body by a mounting cylinder. It is known to consist of a cylinder type pump to be mounted.

However, in this type of container, the number of malicious crimes of refilling the content liquid has been increasing recently, and preventive measures against it are desired. In the conventional container described above, the cylinder type pump is mounted on the container body by detachably fitting the mounting cylinder fixed to the pump to the neck portion of the container body. It was free, and as a result, refilling the content liquid was extremely easy.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a liquid ejection container configured such that refilling of the content liquid is difficult and even if it is possible, the work is extremely troublesome. Is.

"Means for Solving the Problem" A container body 2 in which a mouth / neck portion 5 is erected, a cylinder 11 is inserted into the container body 2, and a liquid ejection head 12 is attached to the mouth / neck portion 5.
And a cylinder pump 3 that is mounted on the container body 2 by means of a mounting cylinder 4 so as to be vertically movable. The liquid in the container is sucked into the cylinder by the vertical movement of the liquid ejection head 12, and In a liquid ejection container configured to eject from the nozzle hole 23 of the head, the cylinder 11 of the pump 3 is non-detachably fitted to the mouth / neck portion 5,
The cylinder 4 is configured to remain in the container body 2 when the mounting cylinder 4 is separated from the mouth / neck portion 5.

[Operation] Since the cylinder 11 is permanently attached to the neck 5 of the container body and the mounting cylinder 4 is removed, the cylinder 11 remains on the container body 2 side as shown in FIG. Refilling the liquid is difficult.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show one embodiment of the container of the present invention, in which 1 denotes a liquid ejection container. The container 1 is a container body 2
And a cylinder type pump 3 and a mounting cylinder 4.

The container body 2 is formed by erecting the mouth / neck portion 5, and
An inward flange 7 is extended from the upper end of the peripheral wall 6, a second peripheral wall 8 is provided upright from the inner peripheral edge of the flange 7, and an engaging protrusion 9 is provided around the outer peripheral upper end of the peripheral wall 8. , The first peripheral wall 6
A thread 10 is provided around the outer circumference of the.

The cylinder type pump 3 is a cylinder to be inserted into the container body.
11 and a liquid jetting head 12 projecting upward and downward from the container body neck 5, the cylinder 11 has an outward flange 13 extending from the upper end of its peripheral wall 13 and
13 A peripheral wall 15 is provided so as to extend from the lower surface, and an engaging protrusion 16 that fits into the engaging protrusion 9 provided on the mouth / neck portion 5 is provided on the inner periphery of the lower end of the peripheral wall 15. The cylinder 11 is attached to the mouth / neck portion 5 of the container body by being fixedly fitted to the ridge 9 of the mouth / neck portion. In addition, the suction valve 17
And a suction pipe 18 is hung from the lower end of the cylinder 11 in the container body 2 so as to communicate with the valve hole of the suction valve 17.

The liquid ejecting head 12 is fitted in the mounting cylinder 4 so as to be vertically movable, and the operating member 20 having a cylindrical piston 19 is connected to the head 12 in series. A thread is provided on the inner circumference of the peripheral wall of the mounting cylinder 4.
21 is provided around, the lower end of the operating member 20 is inserted into the cylinder 11, and the thread 21 is screwed with the thread 10 of the mouth and neck so that the mounting cylinder 4 can be freely attached to and detached from the container mouth and neck 5. The liquid ejection head 12 is attached to the container body 2 so as to be vertically movable. Further, a spring 22 is fitted in the cylinder 11, and the spring 22 urges the operating member 20 inserted in the cylinder upward.

The liquid jetting container 1 configured as described above sucks the liquid in the container body 2 from the pipe 18 by the vertical movement of the head 12 and sucks the valve.
It has a publicly known ejecting mechanism for ejecting the liquid sucked into the cylinder 11 via the nozzle hole 23 of the head 12 through the mounting cylinder 4
When the mounting cylinder 4 is removed from the container body 2 by unscrewing, the cylinder 11 remains in the container body 2 as shown in FIG.

Therefore, even if an attempt is made to refill the content liquid, the presence of the cylinder 11 makes it difficult to refill the liquid.

The present invention is not limited to the above embodiment, and various shapes, materials, structures, etc. can be selected within the scope of the present invention.

For example, the valve mechanism and the like of the cylinder type pump can be appropriately changed to known ones, and various fitting methods of the cylinder that cannot be detached from the neck of the container body can be adopted.

[Advantage of the Invention] As described above, the container of the present invention is a liquid ejection container in which the cylinder type pump is mounted on the container body, and the cylinder is irremovably fitted to the neck of the container body and the mounting cylinder is attached. Since the cylinder is configured to remain in the container body when it is detached from the mouth and neck, refilling the content liquid becomes extremely difficult.

Further, since such an effect can be exhibited without the need for a special member, the cost is not increased correspondingly, and the assembly process at the time of manufacturing the container is also advantageous.
