The present invention has been made in view of the above problems, and it is an object of the present invention to provide a liquid cartridge which can automatically add a content liquid to a dispenser without removing the cap. To provide a container.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the liquid cartridge container of the present invention comprises a blow bottle integrally formed with a neck portion provided with a male screw on the outer periphery, and an outwardly facing bottle which is locked at the upper end of the neck portion of the blow bottle. It has an inner plug that has a flange and is inserted into the neck of the blow bottle, and a female screw that has a circular opening on the top surface and that is screwed into the neck of the blow bottle. A cap is provided, and the inner plug is provided with a circular thin portion.

[0006]

[Action]

 In the liquid cartridge container of the present invention described above, when the container is set in the dispenser, the opening of the cap serves to allow the protrusion at the bottom of the dispenser to pass through, and the thin-walled portion of the inside plug is pierced by the protrusion. This acts like opening a bottle.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a liquid cartridge container according to an embodiment of the present invention with its constituent parts separated from each other. As shown in FIG. , Blow bottle 2, inner stopper 3 and cap 4.

The blow bottle 2 is formed by blow molding using a high-density polyethylene containing an inorganic filler such as calcium carbonate or magnesium silicate to form a rectangular parallelepiped shape as shown in the figure. A cylindrical neck portion 21 having a male screw 21a on the outer circumference is integrally formed at approximately the center of the upper surface thereof. In addition, a protrusion 22 is provided along the periphery on the lower portion, and a groove 23, which functions as a guide when being set in the dispenser, is vertically provided on one side surface.

The inner plug 3 is formed by injection molding a soft resin such as low-density polyethylene or linear low-density polyethylene. As shown in FIGS. 2 and 3, the inner plug 3 has a cylindrical portion 31 and a cylindrical portion 31. It has a bottomed cylindrical shape including a bottom portion 32 that closes the bottom of the portion 31, and a flange portion 31 that projects outward along the upper periphery of the cylindrical portion 31. The bottom portion 32 is provided with a circular thin portion 32a along the periphery thereof. Further, on the lower surface of the flange portion 33, minute protrusions 33a are provided so as to circulate. Here, the cylindrical portion 31 is sized to fit into the neck portion 21 of the blow bottle 2 without any gap, and the flange portion 33 is approximately the same size as the upper end surface of the neck portion 21.

The cap 4 is formed by injection-molding polypropylene, and includes a cylindrical portion 41 and a top surface 42 having a circular opening 42 a, and the inner surface of the cylindrical portion 41 is blown. The bottle 2 is provided with a female screw 41a which is screwed into the male screw 21a of the neck portion 21.

As shown in FIG. 4, the liquid cartridge container 1 is constructed such that the blow bottle 2 is filled with the liquid detergent 5 from the neck portion 21 and the inner plug 3 is fitted into the neck portion 21 and then the male portion of the neck portion 21 is closed. The female screw 41a of the cap 4 is screwed onto the screw 21a and the cap 4 is attached to the neck portion 21 to form a supply form. In this case, by tightly screwing the cap 4, the flange 33 of the inside plug 3 is strongly sandwiched between the upper end surface of the neck portion 21 of the blow bottle 2 and the cap 4, so that the protrusion 33a on the lower surface of the flange portion 33 is formed. To prevent liquid leakage.

The liquid cartridge container 1 supplied in the form shown in FIG. 4 is used by being inserted into the dispenser 6 in an inverted state as shown in FIG. The dispenser 6 is designed to support and fix the cartridge container 1 with the projecting portion 22 of the blow bottle 2 locked by the opening edge of the upper portion, and the center of the bottom is tall and the tip is sharp. The protrusion 61 is formed, and a hole 62 is formed at a predetermined position on the bottom. Therefore, when the cartridge container 1 is inserted into the dispenser 6 and set, the protrusion 61 passes through the opening 42 of the cap 4 and hits the bottom 32 of the inside plug 3, and the thin portion 32a is broken and the thin portion 32a is broken. It is opened as shown in. When opened in this manner, the liquid in the blow bottle 2 flows out into the dispenser and is sent to the washing machine through the drain hole 62. Although not shown, the pipe 7 attached to the vent hole 62 is provided with a valve that is opened / closed by turning on / off the solenoid. By appropriately opening / closing this valve, a required amount of liquid detergent can be washed. To be sent to the machine.

[Effect of device]

 As described above, the liquid cartridge container of the present invention comprises the blow bottle integrally formed with the neck portion having the external thread on the outer periphery, and the outward flange portion that is locked to the upper end of the neck portion of the blow bottle. A combination of an inner plug having a circular opening on the top and a female screw threaded on the neck of the blow bottle is provided on the inner circumference. Moreover, since the inner stopper is provided with a circular thin portion, the thin portion of the inner stopper is pierced by the protrusion when inserted into a dispenser having a protrusion on the bottom, and the liquid naturally flows out. Unlike the conventional method, it is not necessary to remove the cap and hold the bottle by hand to add the content liquid, and simply set it in the dispenser to automatically supply the content liquid. To.
