SCREWING CASING FOR STICK-TYPE COSMETIC
Document Type and Number:
Japanese Patent JP2002125756
Kind Code:
A
Abstract:

To provide a screwing casing for a stick-type cosmetic which is made under consideration of suitability for mass production in processing and assembling.

This screwing casing for a stick-type cosmetic is made up of the following parts: A holding cylinder holds the stick-type cosmetic inside. An inner cylinder has the holding cylinder attached inside in a manner that the holding cylinder can slide but can not rotate and is equipped with a gap, which is an expanded outer diameter, at a lower part of the inner cylinder. A sleeve is held by the inner cylinder in a manner that the sleeve can rotate, is equipped with a spiral groove which has the holding cylinder sliding up and down by screwing together with the holding cylinder, and has a protruded collar which is located on a lower, outside wall of the sleeve and makes contact with the gap formed on the inner cylinder. A main cylinder holds the lower part of the inner cylinder in a manner that it would not rotate but can be pulled out and has plural hooking protrusions on the upper, inner wall. A joining cylinder is joined to the upper part of the main cylinder and has a protruded hook which is joined to a hooking protrusion, is L-shaped or inverted L- shaped and is placed on the lower, outside wall which is inserted in the main cylinder. As the collar located at the sleeve makes contact with the lower end of the joining cylinder, the collar at the sleeve and the lower part of the inner cylinder are held tight between bottom surfaces of the main cylinder. As a result, the sleeve and the inner cylinder are held so that they do fall.
