Description

  The present invention is intended for replacement of cosmetics such as whitening agents, milky lotions, skin lotions, etc., and liquid or granular contents such as hair shampoos, rinses, kitchen detergents, etc. This relates to a replacement container.

  Conventionally, synthetic resins such as polyethylene having excellent mechanical properties and chemical resistance have been used for cosmetics such as whitening agents, emulsions and lotions, and containers for hair shampoos, rinses and kitchen detergents. In addition, many pumps that can stably pour out liquid contents and a hinge cap for taking out liquid or granular contents are used.

  In many cases, these containers have been disposed of as trash when the contents have been used. However, recently, these containers can be used repeatedly from the viewpoint of environmental problems, resource saving, and prevention of deterioration of contents. Containers, single-use containers, or methods that reduce the amount of waste as much as possible are required for commodities.

  As one means for answering such a requirement, Japanese Patent Application Laid-Open No. 7-17538 discloses that a replacement container body having a mouth is filled with contents, and this replacement container body is provided with an exterior having a stable mechanical strength. A technique for detachably attaching an interior to the body is shown.

  In the above prior art, the contents can be easily poured out while maintaining stable independence. After use, only the replacement container body is discarded, and functions such as a pump and a cap are provided. Since the exterior body including the part only needs to be reused, a considerable reduction in garbage can be realized.

  However, in the prior art disclosed in the above-mentioned Patent Document 1, in order to assemble and fix the container, in addition to the replacement container body and the exterior body, a shoulder ring is used, and various locking structures are provided. The structure is such that the replacement container body is locked and fixed to the exterior body. In this case also, the manufacturing cost increases, and the replacement operation of the replacement container body becomes complicated and the replacement container body is unnecessary. There was a problem of unauthorized removal due to the rotation.

JP 7-17538 A

  Therefore, the present invention has been devised to solve the above-mentioned problems in the prior art, and the attachment and detachment of the replacement container body with respect to the exterior body can be stably performed by a simple rotational displacement of the lock cylinder provided exclusively. It is an object of the present invention to make it easy to achieve, so that the replacement container body and the exterior body can be easily attached and detached, and the stable assembly of the replacement container body to the exterior body is maintained.

The main configuration of the present invention for solving the above technical problem is:

In the case where the bulging inner surface portion is provided so as to abut against the outer surface of the outer body and the rising engagement piece is provided so as to be engaged with the engagement protrusion of the exterior body from above, a stable “lock state” is obtained. It can be obtained and the structure with the locking assembly can be simplified.

  If the engaging inner cylinder of the exterior body is provided with a split groove, a part of the engaging inner cylinder is used as a locking tongue piece. It can be made to oppose a surrounding surface part.

  For this reason, the locking tongue piece and the bulging inner surface portion formed on the inner peripheral surface portion of the lock cylinder have a positional relationship that can be opposed to each other, and an appropriate combination structure of the locking tongue piece and the bulging inner surface portion. Can be easily obtained.

  If the inner peripheral edge of this top wall is left in a part of the top wall of the exterior body to open an opening notch, and the inner peripheral edge of the remaining top wall is used as a locking projection, It is easy to form the stop protrusion and eliminates the need for a dedicated space for positioning the rising engagement piece, thereby simplifying the assembly structure in which the exterior body and the lock cylinder cannot be detached. In addition, the height of the container can be reduced.

  When the circumferential width of the bulging inner surface of the lock cylinder is set to a value smaller than the circumferential width of the locking tongue of the exterior body, a simple and stable switching operation can be obtained. Can do.

  If the lock cylinder is provided with a finger-hook piece exposed in the window hole, the lock cylinder can be easily rotated, so that the lock cylinder is easy to rotate and the lock cylinder is small. Can be operated with operating force.
