The problem to be solved by the invention is that the concave and convex strips of the engaging means of the prior art refilling container are provided at the lower part of the inner and outer containers, and a pair of engaging and disengaging means for detaching the engaging means. The lever is molded as a separate member with both shafts and steps, so it is necessary to operate the upper lever to release the engagement due to the lower ridges. There is a possibility that it may not be able to be chipped and fixed, and since screws and ridges are formed on the upper and lower parts of the inner container, a large amount of waste is required. When replacing the container, the inner container cannot be taken out even if the concave / convex engagement is released by pushing the lever, and it is necessary to temporarily pull the hand from the lever or to lift the inner container with the other vacant hand.

[0004]

According to the present invention, a pair of elastic tongues are vertically provided on the outer end surface of a flange provided on the outer periphery of the upper end of the inner portion of the inner container, and a thin portion at the lower part of the tongue is provided. A fitting means such as a ridge is provided on the outer peripheral surface of the outer container, and the outer container in which the inner container is removably fitted is provided with a notch for fitting a tongue piece of the inner container in the upper end opening portion, The inner periphery of the outer container below the notch is provided with engagement means for engaging and disengaging the engagement ridge of the tongue. The objective of obtaining an economical and easily refillable container with a small number of members and a small amount of waste could be achieved with a simple configuration.

[0005]

The inner container of the above construction is filled with creamy cosmetics, medicines, etc., the inner container is fitted into the outer container from above, and the tongue for engaging the upper end of the inner container is cut off at the upper end opening of the outer container. When fitted into the notch and pushed downward, the engaging means such as the ridge at the lower part of the tongue engages with the engaging means on the inner periphery below the notch of the outer container to fix the inner container, and as a decorative container etc. Can be used. When the cosmetic filled in the inner container is exhausted by repeated use, when the tongue of the inner container is pinched from both sides by fingertips and pushed inward, the engaging means of the outer container and the tongue engage with each other. The inner container can be immediately taken out of the outer container when the tongue piece is pushed and pulled up while being sandwiched. After taking out the inner container, the tongue piece of a new inner container filled with cosmetics and the like is positioned and fitted into the notch for fitting of the outer container and strongly pressed from above. The vessel settles in the outer container.

FIG. The inner container 1 shown in each figure is formed of a relatively thin synthetic resin, and a pair of elastic tongues 2a are integrally extended on the outer end surface of a flange 2 protruding from the outer periphery of the mouth end. A projection 2c is formed as an engagement means on the outer surface of a thin portion 2b formed by cutting out the lower outside of the lower portion 2a. In the figure, 2 '
Is a tongue piece 2a suspended from the outer periphery of the inner container 1 and the outer end face of the flange
Is a gap formed between the back surfaces.

The outer container 3 having a single structure as shown in FIGS. And a pair of notches 5 and 5 for fitting the tongue pieces 2a at the mouth 4 protruding through the shoulders 5a at the upper end of the outer peripheral wall. A concave portion 5b is formed inwardly as an engagement means on the inner periphery of the outer container below the
A screw 5c for screwing the cap 6 is protrudingly provided on the outer periphery of. Incidentally, as the engagement means, the concave portion 5b may be a convex portion. As shown in FIG. 1, the cap 6 screwed to the outer container 3 has a screw 6a projecting from the inner surface of the peripheral wall, and a packing 7 on the inner periphery of the top plate.
Is attached. When replacing the inner container, there is a possibility that the packing 7 has already been contaminated, so that the cap is discarded and a new cap is used.

The outer container 3 having a hollow structure shown in FIG. 3 is slightly thinner than the outer container having the single structure. The shoulder 5a is formed wide and bottomless, and the bottom plate 3 'is fixed thereto. The configuration of the notch 5, the notch 5, 5, the engaging recess 5b, and the screw 5c is almost the same as that of the single-layer outer container. As shown in FIG. 3, the cap to be fitted to the outer container 3 integrally connects the cap 6 and the inner cap 6 'by fitting the concave and convex at the lower end, and the packing 7 is attached to the inner surface of the top plate of the inner cap 6'. At the same time, a screw 6 a is provided on the inner periphery of the inner cap, and is screwed to the mouth 4 of the outer container 3. In addition, when replacing the inner container, the outer cap 6 and the inner cap 6 ′ are disengaged from the concave-convex fitting, and the packing 7, which may be contaminated, and the inner cap 6 ′ on which the fixing is fixed are discarded, and a new cap is removed. The inner cap is attached to the outer cap.

When the contents of the inner container fixed in the outer container after being filled with cosmetics or medicines such as creams are used up, the cap 6 is removed from the outer container 3 and the tongue pieces 2a, 2a of the inner container 1 are finger-touched. When it is sandwiched and pressed inward, the ridge 2 at the lower part of each tongue piece
Since the engaging recess 5b of the outer container 3 is disengaged from the outer container 3, the inner container 1 can be easily taken out from the outer container by lifting the inner container 1 while pressing and holding the inner container. When the inner container is taken out, the presence of the gap 2 'and the elasticity of the tongue piece 2a cause the tongue piece 2a to be removed.
Can be pressed inward

After the inner container is taken out, the outer container 3 is filled with a cosmetic or a drug, heat-sealed, or fitted with a new inner cap to hold a new inner container which is sealed and clean. When the inner container is fitted and the tongue pieces are fitted into the notches 5, 5 for fitting of the outer container and the inner container is pushed downward, as shown in FIG. Engaging protrusion 2c and a concave portion 5a of the outer container.
And the inner and outer containers 1 and 3 are fitted and fixed. When refilling a new inner container fitted with the new inner cap, the original outer cap removed is used repeatedly.

[Effects of the Invention] The refilling container of the present invention having the above-described structure and operation (1) is formed integrally with the inner container without providing a tongue piece for taking out the inner container as a separate member, so that the lever is formed as a separate member. Unlike the prior art, which requires the time of molding and pivoting to a predetermined notch of the outer container, the configuration and molding are simple and economical. (2) Since the tongue piece is integrally molded with the outer end surface of the flange, Unlike the levers of the prior art, there is no need to protrude both side shafts, and there is no possibility that the mounting shaft is thin and breaks due to repeated use. (3) Further, since the tongue piece is integrally formed with the inner container, the inner container can be immediately pulled up and taken out while holding the tongue piece inwardly pressed as an allowance without replacement when replacing.
(4) Since the ridges, which are means for fixing the inner and outer containers, are provided below the tongue of the inner container and below the notch for fitting the tongue of the outer container, the engagement can be prevented. There is no need to overcome the uneven fitting with a strong force as in the prior art to remove, and it is only necessary to press inward, so there is little wear, so the reliability of engagement of the inner and outer containers may be impaired even if used repeatedly. Less is. (5) Since the inner container has a simple configuration in which a thin and narrow flange and a tongue piece are provided at the upper end, molding is simple, and the amount of waste is small and economical.
