2. Description of the Related Art The above-mentioned container is formed in a vertical pump type, and normally, a stem having a cylindrical piston at the lower end is erected upward from a cylinder vertically installed in the container and fitted on the upper end of the stem. When the head with a nozzle is pushed down, the suction valve at the lower end of the cylinder closes, the discharge valve provided at the lower end of the stem or inside the head opens to discharge the liquid in the cylinder, and when the head is released, the discharge valve closes. The suction valve is opened so that the liquid in the container is sucked into the cylinder.

As described above, since the stem is erected in the upward biased state, it is possible to eliminate the disadvantage that the packaging of the container is bulky by keeping the stem and the head in a depressed state during transportation of the container. As the method, the cylinder mouth portion is erected upward, the first screw cylinder is fitted in the mouth portion, and the second screw cylinder suspended from the head is screwed into the screw cylinder by pushing down the stem. Was there.

Since the above-mentioned container has a complicated structure, the number of members tends to increase and the cost also increases. According to the present invention, the first screw cylinder is integrally formed with a mounting cylinder for fixing the cylinder to the container body, and is automatically separated during the assembly of the liquid ejection container, and thereafter becomes two members respectively. It is provided to fulfill the function,
By doing so, the above member is provided so as to be easily manufactured.

FUNCTION The fitting member 1 and the mounting cylinder 7 are integrally molded through the break line 10. When assembling a liquid ejection container using this member, as shown in FIG. 2, the lower part of the stem 20 in which the cylindrical piston and the member with the discharge valve body are previously fitted in the lower end of the cylinder 11 is connected via the spring 23. The stem is inserted into the cylinder portion of the fitting cylinder portion 2 from above the stem, and the fitting member 1 is driven into the cylinder mouth portion so that the fitting cylinder portion 2 is fitted into the cylinder mouth portion. Also, the inward flange 9 of the mounting cylinder 7 is driven so that the lower surface of the inward flange 9 is pressed against the upper surface of the outward flange 12 of the cylinder. Next, as shown in FIG. 3, the liquid ejection head 21 is fitted to the upper end of the stem, and the head is pushed down to screw the second screw cylinder 21a vertically provided from the head onto the inner surface of the fitting cylinder portion 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The member of the present invention is one in which the fitting member 1 and the mounting cylinder 7 are integrally molded with a synthetic resin material through a break line 10.

The fitting member 1 is formed from the upper end of the threaded cylindrical portion 2 to be fitted to the inner surface of the upper end portion of the cylinder 11 of the manual liquid ejection container, and the outer surface of the upper end portion of the cylinder through the outward flange-shaped top wall 3. A short cylinder 4 to be fitted to the above is vertically provided, and a thread 5 for screwing the liquid ejection head 21 is provided on the inner surface of the fitting cylinder 2. An engagement protrusion 6 may be provided on the inner periphery of the lower end of the short cylinder 4.

The mounting cylinder 7 has an upper end of a screw cylinder portion 8 to be screwed onto the outer surface of the mouth / neck portion of the container body, and an outer flange of the outer surface of the cylinder is held between the upper surface of the cylinder body and the top surface of the container body. An inwardly facing flange 9 is attached.

The fitting member 1 and the mounting cylinder 7 have a broken line between the outer circumference of the lower end of the short cylinder 4 and the upper edge of the inner circumference of the inward flange 9.
By being continuous through 10, it is integrally molded with a synthetic resin material. The breaking line is provided so as to be broken by driving the mounting cylinder 7 downward with respect to the fitting member 1 when assembling the liquid ejection container.

Cylinder 11 for mounting the above-mentioned member of the present invention
Has an outwardly facing flange 12 on the outer surface of the upper part thereof, and an engaging projection 13 is provided around the outer periphery of the upper end. Further, the cylinder portion between the concave portion formed by the cylinder portion below the engaging projection and the outward flange 12 is formed in a larger outer diameter portion than the upper portion thereof, and the second engaging portion is further formed at the upper end of the portion. A mating ridge 14 is provided around the ridge and the inner peripheral edge portion 9a of the inward flange of the mounting cylinder is fitted between the ridge and the outward flange 12.

Reference numeral 15 is a suction valve provided on the inner surface of the lower portion of the cylinder 11. 16 is a cylindrical piston, 17 is an inverted skirt
A discharge valve element having 18, which are integrally molded.
That is, from the tubular piston, a tubular portion fitted into the lower end of the stem stands upright, and the rod portion of the discharge valve body is fitted into the tubular portion, and the flow path 19 is provided between them. Is formed integrally with a plurality of connecting plates, and a reverse skirt-shaped portion 18 that expands upward from the upper end of the rod is projected upward and outward, and the outer periphery of the upper end of the reverse skirt-shaped portion is watertight to the inner wall surface of the stem The discharge valve is formed by elastically contacting with.

[0013]

As described above, according to the present invention, the fitting member to be fitted to the upper end of the cylinder and the outward flange screwed on the mouth and neck of the container body and provided on the upper portion of the cylinder are connected to the container mouth. Since the mounting cylinder to be held between the top surface and the top surface is integrally molded of synthetic resin material, the molding cost can be reduced. These two members are the outer circumference of the lower end of the short cylinder 4 and the inner circumference of the inward flange 9. Since the upper edge and the upper edge are integrally formed through the breaking line 10, the breaking line can be separated into two members when the cylinder is driven during assembly, and these two members can be assembled at predetermined positions. Therefore, the container assembling process can be simplified.
