Description

[Detailed description of the invention] The present invention relates to a container for storing bar-shaped cosmetics such as lipstick.

This type of container is constructed as a so-called dispensing container, and is designed so that when the lower part of the container is turned, the lipstick, etc. is dispensed from the upper end of the cylindrical container, and when the container is turned in the opposite direction, the lipstick, etc. can be refilled into the container. It is being

The container has several cylindrical parts screwed together, and each cylindrical part is configured as a cylinder for the purpose of screwing together.

Although such a conventional structure is mechanically superior, on the other hand, the shape of the container is entirely cylindrical, which reduces the scope for improving the shape and design.

The present invention eliminates these drawbacks and reduces the number of cylinders for feeding, and will be described below with reference to the drawings.

The main components of the container are a screw tube, a saucer, a middle tube, and a rotating tube.

The threaded cylinder 1 has a threaded groove 2 on its outer surface, and an engaging protrusion 3 is provided around its lower part.

The lower end portion 4 may be formed into a shape other than a perfect circle, such as a triangular shape.

An engaging groove 5 is provided around the inner surface of the upper end.

The saucer 6 has a peripheral wall 7 as an upper cylindrical portion having a cross-sectional shape other than a perfect circle, such as a triangular shape, and a lower cylindrical portion 8 thereof is rotatably fitted into the upper end of the spiral cylinder.

The lower cylindrical portion has a perfect circular cross section, and an engagement protrusion 9 is provided on the outer surface of its lower end, and is rotatably fitted into an engagement groove at the upper end of the screw cylinder.

The middle tube 10 is fitted onto the outer surface of the screw tube and the saucer.
By engaging the inside of the screw groove 2, the screw can be screwed.

For the saucer, the cross-sectional shape of the middle cylinder is made to be the same as the cross-sectional shape of the peripheral wall 7 of the saucer, so that it can only be moved up and down and cannot be rotated.

In other words, when you hold the lower part of the screw and turn the middle cylinder 10, the slider 11 and therefore the middle cylinder 10 will spiral under the guidance of the screw groove, and the lower cylinder part 8 of the saucer 6 will rotate into the upper end of the screw. Since it is movably fitted, it is provided so that it can rotate while being fitted to the upper end of the screw cylinder.

The rotating cylinder 12 has the same cross-sectional shape as the middle cylinder 10, and the middle cylinder 10 is provided inside the rotating cylinder so that it cannot rotate but can move up and down.

An engaging protrusion 13 is provided around the inner side of the flat end, and is rotatably engaged with the retaining protrusion 3 at the lower part of the screw cylinder.

On the outer surface slightly above the middle is a raised part 14 as a gripping part.
It is a good idea to set up

It is preferable to fix a lower cover 15 to the lower end of the spiral tube 1, and a decorative tube cover 16 is attached to the outer surface of the tube below the raised part of the rotary tube 12.
is fitted.

The lipstick 1 has a triangular cross section by fitting the lower end into the saucer 6.
7 is provided, and 18 is a cap whose cross-sectional shape is also triangular.

In the above configuration, when holding the screw tube 1 through the lower lid 15 and rotating the rotating tube 12, the rotating tube, the middle tube, and the saucer are all formed in a triangular shape and are not perfect circles, so the middle tube 10, the saucer 6 will also be passed along.

Since the middle cylinder 10 has a slider 11 that engages with the threaded groove 2 of the screw cylinder, it simultaneously screws against the screw cylinder, and therefore rises or descends with respect to the rotating cylinder and the saucer.

Since the lipstick 17 is rotated together with the saucer, the inner tube 10 moves up and down relative to the lipstick to expose and cover the upper end of the lipstick.

As described above, the present invention includes the saucer peripheral wall 7, the middle cylinder 10, the rotating cylinder 12,
Since each container is made into a triangular shape or other shape other than a perfect circle, the overall shape of the container is also a shape other than a perfect circle and is not limited to a cylindrical shape as in the past, allowing various external design changes. In addition, since they have a cross-sectional shape other than a perfect circle, they can be fitted together so that they can only move up and down without being able to rotate with each other, and therefore, a cylinder body that prevents rotation is provided as in the past. This is not necessary, and since only the inner tube is moved up and down instead of moving the lipstick up and down, the operation for up and down movement can be performed easily with a small amount of force. Since the inner tube 10 only moves up and down without relative rotation, the lipstick is less likely to break due to contact or the like.

Claims (1)

[Scope of utility model registration request] A saucer 6 comprising a screw tube 1 having a screw groove 2 on its outer surface, a lower tube section 8 rotatably fitted into the upper end of the screw tube, and a peripheral wall 7 serving as an upper tube portion protruding upward from the screw tube. Then, the slider 11, which is fitted onto the outer surface of the screw cylinder and the peripheral wall of the saucer and projected from the inner surface of the lower part, is engaged with the screw groove 2 so that it can be screwed into the screw tube and is slidable against the saucer. The middle cylinder 10 is provided to be movable up and down, and the lower end cylinder part is rotatably engaged with the outer surface of the lower end of the screw cylinder 1, and the middle cylinder 10 is moved up and down between the inner wall surface of the cylinder part and the outer surface of the screw cylinder. It has a rotary cylinder 12 that can be provided,
The cross-sectional shapes of the peripheral wall 7, the middle cylinder 10, and the rotary cylinder 12 of the saucer are shaped so that the middle cylinder 10 can move up and down with respect to the peripheral wall of the saucer and the rotary cylinder, but cannot rotate, other than a perfect circle such as a polygon. A rod-shaped cosmetic container characterized by being formed into the same shape.
