The inner stopper 6 is tightly fitted with a cosmetic such as a liquid medicine or the like.

The shoulder cover 3, which is the gist of the present invention, is formed of a synthetic resin in an annular shape and is inserted through the central opening 3 'through the projecting opening 2c of the inner container 2, and has an elastic outer peripheral end surface. A pair of tongue pieces 3a fitted into the respective notches 5 of the outer container 1 are integrally extended and vertically extended, and project as an engagement means on the outer surface of a thin portion 3b formed by cutting out the lower outer side of the tongue piece 3a. A ridge 3c is formed to engage with the engaging recess 5a of the outer container. In the figure, reference numeral 3d denotes a rib concentrically provided on the inner peripheral surface of the shoulder cover 3 and provided with an engaging recess 3e which is engaged with the engaging projection 2b of the inner container 2 to support the inner container in a retaining state. ing. The recesses 3e and the projections 2b and the projections 3c and the recesses 5a of the engagement means may be opposite to those shown in the drawings. .

The outer container 1 to which the inner container 2 is loosely fitted and fixed.
The inner container is formed by molding synthetic resin to be relatively thicker than the inner container 2 and providing beautiful coloring and decorative patterns on the outer peripheral wall by embossing or other means so that the inner container liquid is exhausted and the inner container is removed. After replacement, it can be used repeatedly without discarding. As described above, the inner plug 6 and the cap 4 are attached to the inside and outside of the upper end protruding opening 2c, and the inner container 2 in which the shoulder 2a is covered with the shoulder cover 3 and is fixed in a retaining state is inserted into the opening 1 of the outer container 1. 'And insert the tongue pieces 3a on both sides of the outer container
Fitted in the notch 5 twice stop shape, the small gap 1a further container 2 engages with the depression of the tongue piece of the ridge 3c and the cutout recess 5a is retaining shape in the outer vessel 1 Is settled and housed. Since the inner and outer containers are not closely fitted, the molding accuracy is not strict. The various liquid containers of the present invention configured as described above are filled with milky lotion, lotion, etc.
When the contents of the inner container 2 fixed inside are used up, the tongue pieces 3a, 3a of the shoulder cover 3 are sandwiched between two fingertips and turned inward.
That is, when the tongue piece 3a is pressed toward the inner container side, the tongue piece 3a is bent by elasticity in the range of the small gap 1a on the rear surface, and the engagement between the lower ridge 3c and the engaging recess 5a of the outer container 1 is released. When the shoulder cover 3 is pulled up in the state of being held, the inner container 2 can be taken out of the outer container 1 together with the shoulder cover 3. Therefore, there are two ways of discarding, one of which is a case where only the outer container 1 is left and the other is discarded. That is, when the inner container 2 and the shoulder cover 3 are inseparable, the shoulder cover 3 is discarded together with the inner container 2, and a new inner container 2 with a shoulder cover enclosing the contents is inserted into the outer container to remove the shoulder cover 3. By outer container 1
Stored and fixed inside. Another is a case where the other is discarded while leaving the outer container 1 and the shoulder cover 3. That is, if the inner container 2 and the shoulder cover 3 can be separated, only the inner container 2 is discarded, a new inner container enclosing the contents is fitted to the original shoulder cover, and inserted into the outer container 1 in the same manner as described above. It is fixed to the outer container 1 by the shoulder cover 3. Further, there is a case where the cap 4 is reused in any of the above cases and a case where the cap 4 is discarded at the same time. When the outer container 1 and the shoulder cover 3 are placed and the other is discarded, the insertion hole of the shoulder cover is closed. By making the outer diameter larger than that of, it can be removed with the cap attached.

FIGS. 3 and 4 show another embodiment of the present invention.
The major difference from the container of FIG.
The inner cap 9 is fitted into the outer container 1 to form a double structure, and the other is that a ridge 5a is formed inwardly as an engagement means on the inner periphery of the lower thin portion of the notch 5,5 of the outer container 1. Only differ. Shoulder cover 3 fitted to inner container 2
A pair of tongue pieces 3a are provided at the lower end of the outer peripheral wall, and the outer peripheral surface of the thin portion 3b which is recessed at the lower portion is provided on the outer peripheral surface of the engaging ridge 5a of the outer container 1.
A rib 3c is provided to project from the central insertion opening 3 '.
d, and the engaging projection 2 of the inner container 2 is inserted into the engaging recess 3e.
b is engaged. The point that a small gap 1a exists between the inner and outer containers 2, 1 is the same as in the embodiment of FIGS. Cap 4 that fits concave and convex with inner cap 9
As shown in FIGS. 3 and 4, an inner cap 9 of the inner and outer walls 7, 8 formed concentrically as shown in FIGS. It is plugged. In the drawing, reference numeral 8 'denotes a slit for facilitating the insertion and removal of the inner cap 9, 8a denotes an annular groove for fitting the outer periphery of the inner edge of the inner cap 9 unevenly, and 8b denotes a knurl for preventing rotation. A knurl (not shown) formed on the outer periphery of 9 engages with each other to perform an integral operation.

When the contents of the inner container 2 are used up in the same manner as in the previous embodiment, the tongue pieces 3a, 3a of the shoulder cover 3 are sandwiched between the two fingertips. When pressed inward, that is, toward the inner container, each tongue piece 3a is bent by elasticity in the range of the small gap 1a on the rear surface, and the engagement between the lower ridge 3c and the engagement ridge 5a of the outer container 1 is released. When the shoulder cover 3 is pulled up while being pressed, the inner container 2 can be easily taken out of the outer container 1 together with the shoulder cover 3.

Next, at the time of replacement, there are two types of discarding in this case as in the above-described embodiment, one of which is to discard the other while leaving the outer container 1, that is, the inner container 2 and the shoulder cover 3 If it is inseparable, the shoulder cover is discarded together with the inner container 2, and a new inner container 2 with a shoulder cover enclosing the contents is inserted into the outer container 1 and fixed to the outer container by the shoulder cover 3. The other is to leave the outer container 1 and the shoulder cover 3 and discard the other, that is, if the inner container 2 and the shoulder cover 3 can be separated, only the inner container is discarded and a new inner container enclosing the contents is placed. It is fitted to the original shoulder cover, inserted into the outer container 1, and fixed to the outer container 1 by the shoulder cover 3. In both cases, the inner and outer caps may be reused, or only the outer cap may be used. If the shoulder cover is to be reused, the shoulder cover can be removed while the cap is still attached to the inner container by making the insertion opening of the shoulder cover larger than the outer diameter of the inner cap.

As described above, depending on the cost or design, (1) In the first embodiment, the other is replaced while leaving only the outer container 1, and (2) The other is replaced while leaving the outer cover 1 and the shoulder cover 3. There are cases where (3) the inner container with the cap fitted with the cap is replaced together with the shoulder cover, and (4) in Example 2, the group to be reused when the shoulder cover and the inner container are inseparable, The inner and outer caps and outer containers, the outer containers and outer caps.
A shoulder cover and an outer container, an outer container and a shoulder cover and an outer cap. In addition, when the shoulder cover is left in the above, the inner diameter of the insertion hole of the shoulder cover is made larger than the outer diameter of the inner cap, so that the inner cap is detached from the shoulder cover with the inner cap attached to the inner container, the outer cap, the outer container, Use the shoulder cover repeatedly.
