Description of the Related Art Containers are being refilled in order to save resources and reduce pollution while maintaining the high-grade appearance of the containers, and to supply them at low cost. As an example of such a container, there is the invention of Japanese Patent Publication No. Hei 4-24045 shown in FIG. In this container, as shown in the vertical sectional view of FIG. 7, the cosmetic itself is filled in an inner container 52 called a refoil container, and in using the container, it is attached to an outer container 51 which is excellent in design and practicality. Used in a state where
2, the inner container 52 filled with new cosmetics is replaced with the outer container 5 in place of the empty inner container 52.
1, and the outer container 51 can be used repeatedly. [0003] That is, the configuration of this liquid refill container is as follows:
It is detachably positioned and mounted on the outer container 51 provided with the decorative cover 51a, and a shoulder cover 53 is screwed onto the outer container 51 so as to cover the opening of the outer container 51 accommodating the inner container 52. The mouth 52b of the inner container 52 is protruded from the insertion opening, and the cap 54 is screwed or fitted into the mouth 52b. The outer container 51 and the inner container 52 are provided with a plurality of concave and convex strips and wide concave grooves and convex strips for positioning and fitting with each other in order to prevent mutual rotation and rattling in the circumferential direction (not shown). The shoulder cover 53 and the outer container 51 are provided with screw portions to be fitted to each other, and the inner and outer containers 52, 51 and the shoulder cover 53 are integrally connected to each other to prevent vertical rattling. It has become. [0004] The structure of the above-mentioned liquid refill container is intended only to make it possible to replace the aesthetics of the outer container and the inner container.
Diversification of the means of sealing the inner container has not been considered much. [0005] The problem to be solved by the present invention is to solve the following drawbacks, which have not been considered so much in the prior art liquid refill container. a. In order to attach and detach the shoulder cover from the outer container, the operability in replacement work is low, since the cap must be removed from the inner container. b. Since the outer container and the shoulder cover are attached and detached by screwing to exchange the inner container, it takes time to attach and detach the shoulder cover, and the shoulder cover is dropped and damaged during the replacement work. c. The sealing means for the lid of the outer container and the inner container to be refilled must have the same structure, and the structure of the lid of the inner container cannot be freely selected. Cannot be selected. d. Since the upper and lower sides of the inner container are sandwiched between the shoulder cover and the bottom of the outer container, a gap may be created under the shoulder cover due to the tightening condition of the user, which may damage the aesthetics or conversely apply too much tightening load. The container may be damaged, and high dimensional accuracy is required in manufacturing. e. Since the outer container and inner container have a structure that directly holds the mating state, the inner container can be inserted and removed by attaching and detaching the shoulder cover, and by inserting and removing the outer container and inner container. Operational precautions are required, and therefore operability is poor. The present invention has been made to solve the above problems in view of the above problems. Means for Solving the Problems [0006] The present invention relates to an inner container formed of a bottle body; And a pair of protrusions are provided at the lower portion of the shoulder at the outside of the short diameter with the center interposed therebetween, and a small protrusion is provided on the inside to engage with the protrusion at the outside of the short diameter. A lower outer body in which a ring which is loosely fitted is inserted; an insertion tube which is inserted in the mouth of the inner container; a communication wall; And an upper armor formed with an elastic piece having a hook at the inner lower end on the longer diameter side of the peripheral wall and engaging with the protrusion on the longer diameter side, and sliding the ring up and down. By doing so, the upper exterior body and the lower exterior body are attached and detached. [0007] An inner container in which the mouth of a bottle filled with a fluid such as a lotion or a liquid shampoo is sealed by an appropriate means is loaded into a lower exterior body, and the mouth of the bottle is opened and opened. . Then, when the upper exterior body is fitted to the mouth of the lower exterior body and pressed downward from above, the insertion tube of the upper exterior body fits into the mouth of the bottle body in a liquid-tight manner and is formed on the peripheral wall of the upper exterior body. The hook protruding inside the pair of elastic pieces and the pair of projections protruding outside the mouth of the lower exterior body gently and elastically engage with each other.
