2. Description of the Related Art For example, as shown in Japanese Patent Application Laid-Open No. H10-249252, a main cylinder is erected from a mounting cylinder fitted to the mouth and neck of a container body, a cylinder is mounted from the front of the main cylinder, and an upper end of the main cylinder. , The front end of the plunger fitted into the cylinder is connected to the upper rear of the vertically mounted trigger which is pivotally attached to the front of the injection cylinder, and the trigger is urged forward. A trigger-type liquid ejection container is known in which a liquid in a container is sucked into a cylinder by swinging a trigger back and forth, and the liquid in the cylinder is ejected from a front end of an injection cylinder.

[0003]

In the above-described trigger type liquid ejection container, when the liquid in the container is used up, the mounting cylinder is unscrewed from the mouth and neck and the main cylinder is removed from the container. Then, the liquid in the refill container is injected into the container from the mouth and neck to perform refill. However, in the case of such refilling, in addition to the cautious injecting work, it is necessary to unscrew and screw the mounting cylinder, which requires some labor,
There has been a demand for a simpler means that does not rely on refilling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a trigger type liquid ejection container according to the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a trigger type liquid ejector, which is a base cylinder 5 having a lower end of an upright cylinder 3 having a suction valve 2 for sucking up liquid, which is vertically suspended through a first outward flange 4 attached to the lower end of the upright cylinder. A second outward flange 6 enclosed and attached to the lower outer surface of the base cylinder
By engaging the inward flange 7 at the upper end with the upper surface,
The cap-shaped cylinder 8 for screwing the mouth and neck of the container body is suspended.

On the other hand, the vertical cylinder 9 fitted to the outer surface of the upright cylinder 3
A cylinder 10 is protruded from the front and an injection cylinder 11 with a nozzle is protruded forward from the upper end of the upright cylinder 3.
When the front end of the plunger 12 fitted inside is connected to the trigger 13 and the trigger 13 is moved back and forth, the liquid in the refill liquid storage bag 50 in the container is sucked into the cylinder 10 and the liquid in the cylinder Is ejected from the nozzle at the front end of the injection cylinder 11.

Reference numeral 30 denotes a container body. The mouth-neck portion 33 is erected from the upper end of the peripheral wall 31 via the shoulder portion 32, and the cap-shaped cylinder 8 is screwed to the outer surface of the mouth-neck portion. On the other hand, the lower end surface of the peripheral wall 31 is opened, and the inner surface of the lower end portion of the peripheral wall is formed on the large inner diameter portion 34 via the downward step, and the lower end outer surface is formed on the large outer diameter portion 35 via the upward step portion. At the same time, triangular fitting holes 36 are formed on both left and right sides of the lower end of the peripheral wall 31.

Reference numeral 40 denotes a bottom plate. The bottom wall 41 is removably fitted to the large-diameter portion 34 of the peripheral wall 31, and the holding cylinder 42 is hung down from the outer periphery of the lower surface of the bottom wall. It is in contact with the lower end of the peripheral wall 31. Further, a triangular fitting protrusion 43 is formed from a middle portion in the front-rear direction on both the left and right sides of the upper surface of the bottom wall portion 41.
An elastic engagement plate 44 having a projection 43
Into the fitting hole 36 in a detachable manner. Further, an elastic bearing piece 45 having a shaft hole is projected from a front portion of the upper surface of the bottom wall portion 41, and a thin hinge 46 is formed from a rear portion of the upper surface of the bottom wall portion 41.
, The fixing rod 47 is projected, and the front end of the fixing rod 47 is detachably fitted to the shaft hole of the elastic bearing piece 45. In the above description, the elastic engagement plate 44 protrudes from the upper surface of the bottom wall portion 41, but is not limited thereto, and may protrude from the outer peripheral surface of the gripping cylinder 42.

Reference numeral 50 denotes a refillable liquid storage bag, which stores a water-resistant and flexible bag 51 in the container 30,
The lower end is wound around the fixed rod via a gap between the upper surface of the bottom wall 41 and the fixed rod 47. The bag body 51 has an oval bottom wall having substantially the same shape as the cross-sectional shape of the peripheral wall 31, and has a vertically longer length than a normal bag, so that a portion to be wound around the fixing rod 47 is formed. Is secured.

Reference numeral 60 denotes a suction pipe, which hangs a rigid elongated cylinder from the lower end of the upright cylinder 3 to the upper central portion of the container body 30 and forms the sharp end by inclining the lower end of the elongated cylinder. The lower end is pierced watertight into the upper central portion of the refilling liquid storage bag 50.

Next, the operation of the present embodiment will be described.
To store the refillable liquid storage bag 50 in the container 30, the upper end of the refillable liquid storage bag 50 is wound around the fixing rod 47 as shown in FIG. Piece 4
After the engagement with the shaft hole of No. 5, the bag 50 is stored in the container body 30 with the bottom plate 40 facing upward as shown in FIG. As described above, since the suction pipe 60 is located at the center of the container 30, the pipe can pierce the center of the bottom wall of the bag 50. Moreover, since the pipe 60 is relatively short, it does not break or bend when piercing.

In order to fit the bottom plate 40 to the inner surface of the peripheral wall 31, the two elastic engaging plates 44 are slightly bent inward so that the right and left side surfaces of the fitting projection 43 are engaged with the inner surface of the lower end of the peripheral wall 31. In this state, the bottom wall portion 41 may be pushed into the peripheral wall 31,
Then, the fitting projection 43 descends along the inner surface of the peripheral wall and fits into the fitting hole 36, and at the same time, the bottom wall 41 also fits into the large inner diameter portion 34. In order to remove the bottom plate 40 from the peripheral wall 31, the bottom plate 40 may be lifted in a state where both the fitting projections 43 are pushed inward and separated from the fitting holes 36.

In order to eject the liquid, the trigger 13 may be swung in the front-rear direction.
The liquid in the cylinder 0 is sucked into the cylinder 10, and the sucked liquid in the cylinder is ejected from the injection cylinder 11. When the liquid in the bag 50 decreases, the inside of the bag 50 becomes negative pressure and the bag becomes flat and thin. Therefore, even if the suction pipe 60 is short, the liquid in the lower portion of the bag cannot be sucked.

[0015]

According to the first aspect of the present invention, in the trigger type liquid ejection container, the lower end of the suction pipe is inclined to pierce the refilling liquid storage bag stored in the container body, and the peripheral wall of the container body. Since the bottom plate is detachably fitted to the inner surface, the bag can be mounted simply by storing the bag in the container from the bottom of the container, and the bag can be exchanged with one touch.
