Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a cartridge-type, rod-shaped cosmetic dispensing container.

[Conventional technology]

Conventionally, a holding tube that fits and holds a bar-shaped cosmetic material, a guide tube that stores this holding tube in a rotatable but vertically slidable manner, and a structure that covers the bar-shaped cosmetic material, the holding tube, the guide tube, etc. A cartridge that is equipped with a feeding mechanism whose main component is a sleeve and that has an engagement hole in its lower end surface, and a structure that enters through the engagement hole of this cartridge and is rotatably attached to the cartridge. For example, a number of cartridge-type rod-shaped cosmetic containers have been proposed that are comprised of a holder in which an engaging body that engages with a guide tube or a spiral tube stands upright from the bottom surface. This type of configuration has been able to provide a cartridge type container with high reliability and simple construction.

[The problem that the idea aims to solve]

However, since the engaging body of the holder protrudes into engagement with the lower part of the structure rotatably built into the cartridge, if the engagement between the structure and the engaging body is too strong,
There was a risk that the structure or engaging body would fall off when the cartridge was removed. Therefore,
The engagement between the cartridge and the holder could not be made very strong, and the structure would spin idly during rotation, resulting in a poor operating feel. In addition, the cartridge sometimes accidentally fell out of the holder.

[Means to solve problems]

The cartridge A includes a holding cylinder 2 that fits and holds a rod-shaped cosmetic 1 and has a screwing piece 3 protruding from the side wall, and a holding cylinder 2 that is vertically slidable inside, and a screwing piece of the holding cylinder 2 on the side wall. A guide groove 5 through which the guide groove 3 penetrates is vertically bored, convex ribs 10, 10' are provided on the upper and lower outer walls of the guide groove 5, and a step 6 is provided on the lower end side wall to engage with the bottom surface. A spiral strip 9 is rotatably held between a guide tube 4 having a hole 7 and convex ribs 10, 10' of the guide tube 4, and has a side wall to which the threaded piece 3 of the holding tube 2 is screwed. A helical tube 8 has a spiral tube 8 screwed thereon, a sleeve 11 that fixes the helical tube 8 to the inner wall and covers the lower part of the guide tube 4, and a sleeve 11 that is fixed to the lower end of the sleeve 11 and engages the guide tube 4. A through hole 14 through which the hole 7 is exposed is drilled, and the stepped portion 6 of the guide tube 4
and a tail plug 13 that comes into contact with the tail plug 13.

The holder B is inserted and fixed to the outer cylinder 15 and the lower end of the inner wall of the outer cylinder 15, inserted into the center through the through hole 14 of the cartridge A, and elastically locked to the side wall of the engagement hole 7 of the guide cylinder 4. It has an engagement body 22 in which an engagement tube 21 in which a spring piece 20 is cut out stands, and an insertion part 17 that is fixed to the outer tube 15 and into which a cap 16 is removably fitted. Engagement body 22
It is composed of a middle cylinder 18 that comes into contact with the upper end.

The cartridge A and the holder B are detachably attached to each other.

[Effect]

When cartridge A is attached to holder B, the engaging tube 21 of holder B is attached to cartridge A.
The spring piece 20 enters into the cartridge A through the through hole 14, and is elastically engaged with the side wall of the engagement hole 7 formed in the bottom surface of the guide cylinder 4. When in use, by holding the sleeve 11 of the cartridge A and rotating the holder B, the guide tube 4 rotatably housed inside the sleeve 11 will be inserted into the engagement hole 7, and the engagement tube 21 of the holder B will be elastically inserted. Because the release is locked, holder B
The retaining cylinder 2 rotates together with the helical cylinder 8 which is fixed to the inner wall of the sleeve 11 and does not rotate.
A rod-shaped cosmetic 1 which is fitted and held in the container is moved up and down.

When removing the cartridge A, it is sufficient to hold the holder B and pull out the cartridge A against the resilient locking force of the engagement tube 21. At this time, the holder B is attached to the tail plug 1 fixed to the rear end of the sleeve 11.
3 comes into contact with the stepped portion 6 of the guide tube 4 to prevent the guide tube 4 from falling off. Similarly, in the holder B, the lower end of the middle cylinder 18 contacts the upper end of the engaging body 22 to prevent the engaging body 22 from falling off.

〔Example〕

A holding tube 2 that holds the bar-shaped cosmetic material 1 has a threaded piece 3 protruding from a side wall thereof. This holding cylinder 2 is installed inside the guide cylinder 4 so as to be vertically slidable. The guide tube 4 has guide grooves 5 formed vertically in its side wall through which the screwing pieces 3 of the holding tube 2 pass, and guides the holding tube 2 non-rotatably and slidably up and down. Convex ribs 10 and 10' are provided around the upper and lower outer walls of the guide cylinder 4, respectively. Further, the lower outer wall of the guide tube 4 is provided with a stepped portion 6 having a smaller diameter on the lower side, and an engagement hole 7 is bored in the lower end surface. A spiral tube 8 is sandwiched between the convex ribs 10, 10' of the guide tube 4, and is held rotatably but not detachable. This spiral tube 8 has a spiral strip 9 screwed onto the side wall thereof, into which the screw piece 3 passing through the guide groove 5 is screwed. This spiral tube 8 has a sleeve 11
It is inserted and fixed inside. The upper end of this sleeve 11 serves as a recess hole 12 through which the rod-shaped cosmetic material 1 enters and retracts, and the lower end covers the lower end of the guide cylinder 4. A tail plug 13 is fixed to the lower end of the sleeve 11. This tail plug 13 has a through hole 14 through which the engagement hole 7 at the lower end of the guide tube 4 is exposed, and the upper end abuts against the step 6 on the side wall of the guide tube 4 so that the guide tube 4 cannot be removed. It is held in The above is cartridge A.

Next, the holder B to which the cartridge A is removably attached will be explained. An engagement body 22 is housed inside the outer cylinder 15 . This engaging body 22 is
The bottom surface is shaped like a dish, and this side wall is the outer cylinder 1.
5 It is inserted and fixed to the lower end of the inner wall. This engaging body 2
An engagement cylinder 21 that projects into the engagement hole 7 of the guide cylinder 4 of the cartridge A is erected at the center of the cartridge A. A plurality of spring pieces 20 are cut out in the side wall of the engagement cylinder 21 and are elastically engaged with the inner wall of the engagement hole 7 to transmit rotation of the holder B to the guide cylinder 4. Furthermore, a middle cylinder 18 is fixed to the outer cylinder 15 and has an insertion part 17 into which a cap 16 is removably inserted. The opening of this middle cylinder 18 serves as a mounting opening 19 into which the cartridge A is inserted. Further, the lower end of the middle cylinder 18 comes into contact with the upper end of the engaging body 22, making it impossible for the engaging body 22 to fall off.

[Effect of idea]

As explained above, in the present invention, the upper and lower convex ribs 10, 10' protruding from the side wall of the guide tube 4 form the helical tube 8.
The helical tube 8 is inserted into and fixed to the inner wall of the sleeve 11, and a tail plug 13 which comes into contact with the stepped portion 6 of the guide tube 4 is fixed to the lower end of the sleeve 11. Therefore, even if a force in the direction of removal is applied to the sleeve 11 when the cartridge A is removed, the force is transmitted to the guide tube 4 through the tail plug 13, so that the spiral shape is easily removed by climbing over the convex ribs 10, 10'. The stress does not act directly on the cylinder 8, and the feeding mechanism is prevented from being damaged, resulting in increased strength.

Therefore, the engagement force between the cartridge A and the holder B can be made stronger than before, so that the engagement tube 21 of the holder B does not idle in the engagement hole 7 of the guide tube 4, and the rotating and feeding operation can be performed smoothly. In addition, it is possible to prevent the cartridge A from accidentally falling off.

Furthermore, if the engagement force between the cartridge A and the holder B is strengthened, a load will be placed on the engaging body 22 of the holder B, but the upper end of the engaging body 22 will be
Since the engaging body 22 is in contact with the lower end of the cartridge A, the strength of the engaging body 22 is also increased, and the strength matches that of the cartridge A.
