[Problems to be solved by the device]

 In the conventional discharge container described above, the container body and the pump are integrally connected by the drive fitting of the lower part of the pump to the upper end part of the container body, and the entire body is discarded after use, but it is resource-saving. From the point of view, reuse of the pump is desirable, and after using the cream in the container, it is recommended to replace it with a new container filled with cream. However, the replacement requires that the connection between the container body and the pump be watertight, reliable, and easy.

In the present invention, a screwing portion and a sealing portion are provided on the container body and the pump, respectively, so that the consumer can replace the pump with the new container.

【Example】

 First, a known structure of the first embodiment shown in FIG. 1 will be described. 1 is a pump main member, and the main member has a first outward flange 4 from a lower end of a cylinder 3 having a suction valve 2 at a lower end. The first inner cylinder 5 stands up to the middle portion of the cylinder via the second inner cylinder 7 from the upper end of the first inner cylinder via the second outward flange 6, and the third inner cylinder extends from the lower end of the second inner cylinder to the third position. The outer cylinder 9 is erected slightly lower than the cylinder 3 via the outward flange 8. A first vent hole is formed in the third outward flange 8.

An auxiliary member 11 may be fitted on the pump main member 1. The auxiliary member folds the upper end of the main cylinder 12 fitted to the outer surface of the cylinder 3 back to the inner surface of the upper part of the cylinder, and expands the upper part outward from the fourth outward flange attached to the middle of the main cylinder, The engagement cylinder 13 with a vent is erected.

Reference numeral 15 denotes an actuating member, in which a stem 17 stands up from a cylindrical piston 16 fitted in the cylinder 3, and a push-down head 19 with a nozzle 18 is fitted to the upper end of the stem. The head hangs a peripheral wall 20 from the outer circumference of the top wall, and the lower part of the peripheral wall is fitted between the engaging cylinder 13 and the outer cylinder 9 so as to be vertically movable.

Reference numeral 21 denotes a spring that biases the actuating member 15 upward, and is mounted between the fourth outward flange and the lower surface of the top wall of the push-down head.

Reference numeral 22 is a cap, and the lower part of the peripheral wall 23 is detachably fitted to the outer cylinder portion above the ridge 9a provided on the outer surface of the intermediate portion of the outer cylinder 9 described above.

A container body 27 in which a pump is formed by using the pump main member 1 and the actuating member 15 as main members, and the sliding bottom plate 26 is fitted in the lower part of the body portion 25 so that the pump can rise. Fit the upper end of the. The fitting is such that the upper portion of the body portion 25 is placed on the outer surface of the lower half of the outer cylinder 9 and the sealing cylinder portion 29 is erected from the lower end of the upper portion through the inward flange 28 to form the first inner cylinder 5 and the second inner cylinder Tightly fit between 7 and. The fitting is performed by pumping the engaging projections provided on the fitting parts.

In the present invention, the lower half of the outer cylinder 9 is formed in the male screw cylinder 9b, and the upper part of the container body 25 is formed in the female screw cylinder 25a, and the sealing cylinder part 29 is left as it is. The lower half of the outer cylinder 9 of the pump is screwed onto the body so that the sealing cylinder 29 is tightly fitted between the first inner cylinder 5 and the second inner cylinder 7.

In the embodiment shown in FIGS. 2 and 3, the mouth-neck portion which stands up from the upper end of the body portion 25 through the shoulder portion 30 without fitting the upper portion of the body portion 25 into the lower half of the outer cylinder 9. 31 was used as a male screw cylinder, and this male screw cylinder was screwed into the female screw cylinder formed by the second inner cylinder 7. The inner surface of the mouth / neck portion 31 is brought into water-tight contact with the outer surface of the first inner cylinder 5. An O-ring 32 may be fitted on the upper end of the first inner cylinder 5. The outer surface of the lower half of the outer cylinder 9 is a gripping cylinder portion for screwing a pump, and a non-slip projection 33 is provided in either the vertical or horizontal direction.

FIG. 4 shows the replacement container body for the above-described first embodiment, in which the peripheral wall 35 to be screwed into the female screw cylinder 25a is hung from the top wall 36 and the center of the top wall is A cap 38 is formed by fitting a plug portion 37, which is formed by recessing the bottom portion and is closed on the lower surface, into the inner surface of the sealing cylinder 29 in a watertight manner. The cap used for the replacement container body of the second embodiment may have a commonly used shape.

[0016]

[Effect of device]

 In the case of claim 1, the lower half of the outer cylinder of the pump main member is formed on the male screw cylinder 9b, and the upper part of the container body 25 is formed on the female screw cylinder 25a. Since both cylinders are screwed together, and the sealing cylinder portion 29 standing upright from the lower end of the female screw cylinder via the inward flange 28 is tightly fitted between the first and second inner cylinders 5 and 7 of the pump. It is easy to screw the pump into the upper part of the container body 27 by using the upper half of the outer cylinder 9 and to unscrew it. Further, together with the above-mentioned screwing, the sealing cylinder portion 29 has the first and second inner cylinders Since they are fitted tightly between 5 and 7, the above-mentioned screwing will not be loosened by the pressure contact between the inner and outer surfaces of the sealing cylinder against these two cylinders.

In the case of claim 2, since the lower half of the outer cylinder 9 is the gripping cylinder portion, the pump can be attached to and detached from the container body 27 even if the cap 22 is fitted to the upper half of the outer cylinder. Since the inner surface of the mouth / neck portion 31 screwed to the female screw cylinder is watertightly pressed against the outer surface of the first inner cylinder 5, the looseness of the screwed portion can be prevented by the frictional resistance, and the pump can be attached to the container body. You can be sure.
