[Prior art]
For example, a container that distributes a creamy liquid having a relatively high viscosity as a sample for advertising is often required to be simple and inexpensive to manufacture due to its nature. Therefore, for example, an extremely simple type consisting of a bottomed cylindrical main body having an open upper end and a bottom plate-like lid that is detachably provided by closing the upper end opening of the main body is used. Yes.
[0003]
However, when the contents are to be used in a fixed amount and divided into a plurality of times, such a container is not suitable, and a plurality of extremely small containers containing a single dose must be prepared. Therefore, it seems that the use of this kind of container is sufficient if it is miniaturized to one time, but this time, the container is small and difficult to handle.
[0004]
On the other hand, as a liquid discharger that discharges this type of high-viscosity liquid or the like, a bottle-type container body equipped with a pump is generally known. As these pumps, for example, a pump having a cylinder whose bottom end is suspended and fixed by a mounting cylinder screwed to the container neck and neck portion, and is connected to a piston that slides in the cylinder. An operating member having a pressing head fitted to the upper end of the cylinder is provided so as to be able to be pushed down in an upward biased state, and a suction valve is provided in the lower part of the cylinder, and a discharge valve is provided in the dispensing cylinder.
[0005]
These are convenient to handle because the contents can be separated simply by pressing down the operating member, and a relatively fixed amount of liquid can be discharged by pressing the operating member once, but the structure is complicated. , Manufacturing costs are high.

In the illustrated example, the lower surface is brought into contact with and locked to the upper surface of the flange 8 of the container body 2 so that the lower end portion of the peripheral wall 25 is detachably fitted to the upper end portion of the outer peripheral surface of the container body 5 and the upper surface is flatter than the upper end edge of the peripheral wall 25. A cap 24 is formed by extending the top wall 26.
[0022]
By providing such a container body 2 and a cap 24, the container body 2 and the cap 24 are configured so that the liquid can be smoothly filled. FIG. 2 shows an example thereof. In the state in which the container body 2 is separated from the auxiliary cylinder 2a and the main cylinder 2b, the operating member 3, the ring member 21 and the cap 24 are attached to the auxiliary cylinder 2a. As shown in (a), the auxiliary cylinder 2a is filled with liquid from above in an inverted state. Next, as shown in FIG. 2B, the main cylinder 2b is fitted from above. At this time, the air in the main cylinder 2b escapes to the outside through the concave groove 7, so that the main cylinder 2b can be easily fitted.
[0023]
Further, as shown in FIG. 2 (c), when the main cylinder 2b is completely fitted into the auxiliary cylinder 2a, the recessed groove 7 does not reach the lower end of the cylinder wall 6, so that the formed container body 2 includes the auxiliary cylinder 2a and the main cylinder. The liquid filling is finished in a state in which the cylindrical wall 6 is closely fitted at the lower end portion and the airtightness is maintained. Although some air remains in the inner bottom portion of the container body 2, since the viscosity of the liquid to be filled is high and the air is in a slightly compressed state, it is completely separated from the lower end of the container body when the container is used Thus, air remains and there is no harmful effect of the discharge operation.
[0024]
When the liquid ejector 1 configured as described above is used, the cap 24 and the sealing material 19 are removed from the state shown in FIG. 3A, and then, as shown in FIG. When the ring member 21 is screwed up and then the actuating member 3 is pushed down, as shown in FIG. 3C, the engagement protrusion 20 is pushed down until it comes into contact with the upper surface of the container body 2 and is pressurized. A substantially fixed amount of liquid is discharged from the nozzle 12.
[0025]
