Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a dispensing container for accommodating a bar-shaped solid cosmetic such as lipstick.

"Prior Art" Generally, a dispensing container includes a helical tube having a spiral groove formed on its inner circumferential surface, a guide tube rotatably inserted into the helical tube and having an elongated hole extending along the axial direction.
The guide tube is equipped with a tray in which a protrusion is formed to engage with the spiral groove of the spiral tube through the long hole of the guide tube, and a bar-shaped cosmetic is fitted into the tray. , is configured to be fed out by rotating the helical tube and the guide tube.

By the way, in such a dispensing container, for the purpose of improving the design, etc., a decorative tube is provided on the outer periphery of the base end of the spiral tube and the guide tube to cover the outer periphery thereof.

``Problems that the invention aims to solve'' However, in dispensing containers equipped with such cosmetic tubes, the cosmetic tube was fixed by means such as doweling or ultrasonic welding, which caused the following problems. arise.

In other words, if the decorative tube is fixed by doweling, the dowels are directly attached to the spiral tube or guide tube, which may deform and make it difficult to raise and lower the tray. In the case of welding, workability is poor and costs tend to be high.

Therefore, as a means to solve such problems, a dispensing container shown in FIGS. 7 and 8 has been proposed (Japanese Utility Model Publication No. 58-23294). This is spiral tube 1
An annular groove 2 is formed on the outer periphery of the inner tube 5, and a rotation prevention protrusion 3 extending in the axial direction is provided on the outer periphery of the annular groove 2 to prevent the decorative tube 4 from coming off. A split groove 6 that fits into the anti-rotation protrusion 3 is formed, and a locking protrusion 7 that is bent inward at the base end of the split groove 6 and engages with the upper edge 2a of the annular groove 2 The upper edge 2a of the annular groove 2 and the inner fitting tube 5 are restricted from idling by the uneven fitting of the anti-rotation protrusion 3 and the split groove 6.
By coupling with the locking protrusion 7, the inner tube 5 is prevented from coming off and the decorative tube 4 is fixed.

However, in such a conventional structure, since the locking protrusion 7 protrudes from the inner circumference of the inner fitting cylinder 5,
It is difficult to fit the inner tube 5 between the decorative tube 4 and the spiral tube 1, and the locking protrusion 7 is small.
There were problems that needed to be solved, such as the fact that manufacturing was troublesome and the cost was likely to be high.

"Means for Solving the Problems" The purpose of the present invention is to effectively solve the above-mentioned problems. A locking protrusion is provided on either side to prevent the inner tube from coming off and rotating in the circumferential direction, and a guide surface is formed at the tip of the locking protrusion that tapers toward the tip. Further, a fitting groove that fits into the locking protrusion is formed in the inner fitting tube with its tip opening at the base end of the inner fitting tube, and a part of this fitting groove is provided with the fitting groove that fits into the locking protrusion. An engaging convex portion that engages with the base end portion of the stop protrusion is provided.

"Function" According to the dispensing container of the above means, when the decorative tube is inserted into the outer periphery of the proximal end of the spiral tube and the guide tube, and the inner tube is fitted, the locking protrusion is guided into the fitting groove. The fitting protrusion of the fitting groove engages with the locking protrusion at the end of the fitting. In this state, the engagement protrusion of the fitting groove and the locking protrusion engage with each other to prevent the inner tube from coming out and rotating toward the distal end, and the decorative tube is prevented from rotating. It is supported in a fixed state by the inner tube.
