Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stick-shaped cosmetic product dispensing container for dispensing stick-shaped cosmetic products such as lipsticks for use.

"Prior Art" This type of dispensing container is very well known. An example thereof will be described with reference to FIG. 4. The upper half of the main cylinder 1 serving as the main body is a middle cylinder 2 having a slightly smaller outer diameter, and a screw cylinder 3 is fitted to the outer surface of the middle cylinder 2 to form a middle cylinder. A vertically slender guide hole is formed by inserting a cylindrical inner plate 5 holding the cosmetic 4 into the upper part 2 so as to be able to move up and down, and by punching the inner plate 5 on both sides of the inner cylinder 2 by engaging protrusions 6, 6 on both sides. Through a pair of spiral grooves 8 and 8 on the inner surface of the screw cylinder 3 through
And the screw cylinder 3 are relatively rotated in the opposite directions, so that the cosmetic 4 is drawn out and put in.

[Problems to be solved by the invention] In this type of feeding container, it is difficult to insert and mount the cosmetics 4 in the inner tray 5 while assembling the inner tray 5 at the time of assembly. Engagement groove 9 is provided in the center of the main cylinder 1 and an opening 10 is formed in the center of the base 1a of the main cylinder 1. As for the cosmetics 4, as shown in FIG. A transparent cosmetics-filling mold cover 11 called a cosmetic-shaped ogive is attached to the upper part of the middle plate 5 through the engaging groove 9, and the container 4 is turned upside down to pour the cosmetics 4 into the mold cover 11 and the middle plate. Means for filling 5 are taken.

After filling the cosmetics 4, the inner plate 5 is put in, and at this time, the lower end surface of the mold cover 11 is locked to the upper end surface of the middle cylinder 2 and the mold cover 11 is removed. The opening 10 is sealed and closed by a seal plate 12.

However, since the lower end of the mold cover 11 is fitted to the upper end of the middle plate 5 and is engaged with the engaging concave groove 9 by the engaging projections 13 at two to three circumferential positions, the mold cover 11 is engaged. If there is slack in the product, the mold cover 11 may come off when filling cosmetics.

The object of the present invention is to obtain a stick-shaped cosmetic dispensing container having a mounting structure in which a mold cover for filling cosmetics cannot be easily removed when filling cosmetics, and which is provided so that the stick-shaped cosmetic can be formed to have a diameter larger than the diameter of the container.

"Means for Solving the Problem" A main cylinder 1 having elongated vertical guide holes 7, 7 formed on both sides of the middle cylinder 2 standing upright from the upper end of the operation cylinder, and a screw cylinder 3 fitted onto the middle cylinder 2 And a cylindrical inner tray 5 for holding cosmetics, which is fitted into the inner cylinder 2 and engages the engaging protrusions 6, 6 on both sides through the guide holes 7, 7 with the spiral grooves 8, 8 on the inner surface of the screw cylinder 3. The inner plate 5 is extended to the upper limit position where the upper part thereof protrudes above the container opening, and a mold cover 11 for filling cosmetics is externally fitted on the upper part of the inner plate 5 so as to be upside down, and the mold is inserted from the base opening 10 of the main cylinder 1. In the stick-shaped cosmetic product feeding container for filling the cosmetics 4 into the cover 11 and the middle plate 5, the upper part of the screw cylinder 3 is erected above the middle cylinder 2 and the screw cylinder 3 portion above the middle cylinder 2 is made to have a large inner diameter portion. The mold cover 11 fitted to the upper outer surface of the inner tray 5 by the inner peripheral edge of the inward flange-shaped wall 14 attached to the upper end of the inner diameter portion and the upper outer surface of the inner tray 5. Parts is sandwiched and and and the engaging projections 15 ... in which a plurality of attached to the outer surface lower end of the mold cover is engaged with the lower surface the inward flange-like wall 14.

[Operation] In the above, the mold cover 11 for filling is externally fitted to the upper part of the inner plate 5 which is extended to the upper limit position. It is sandwiched between the inner peripheral edge of the facing flange wall 14 and the mold cover 11
Since the engaging projection 15 provided on the outer surface of the lower end engages with the lower surface of the inward flange-shaped wall 14, the mounting state thereof is stably maintained, and the cosmetic article 4 is prevented from coming off due to external force or the like. Absent.

When the mold cover 11 is removed, the inner plate 5 is put downward as shown in FIG. 2 to eliminate the sandwiched state of the mold cover 11, and then the mold cover 11 is forcibly pulled out.

[Embodiment] An embodiment will be described below with reference to the accompanying drawings. The present invention has a mounting structure in which a mold cover for filling cosmetics does not easily come off from a middle plate when filling cosmetics, and the diameter of a container for storing a stick-shaped cosmetic is It is characterized in that it is provided so as to have a larger diameter than the above, and is composed of a main cylinder 1, a screw cylinder 3, a middle plate 6 and a mold cover 11.

The main cylinder 1 has vertically elongated guide holes 7, 7 on both sides of the middle cylinder 2 standing upright from the upper end of an operation cylinder (not shown).

The screw cylinder 3 is fitted onto the middle cylinder 2 and has spiral grooves 8 and 8 on its inner surface.
And the upper part has a large inner diameter portion, and a gap is provided between the lower surface of the inward flange-shaped wall 14 attached to the upper end of the large inner diameter portion and the upper end surface of the middle cylinder 2.

The mold cover 11 has a peripheral wall extending vertically from the outer peripheral edge of the hemispherical top wall,
An outward flange 16 is formed on the lower portion of the peripheral wall, and a plurality of engaging projections 15 are attached to the outer surface of the peripheral wall portion below the outward flange, and as shown in FIG. When the lower part of the peripheral wall of the mold cover is fitted to the upper outer surface of the plate 5, the lower part of the peripheral wall is sandwiched between the upper outer surface of the middle plate 5 and the inner peripheral edge of the inward flange-shaped wall 14, and the engaging projection is formed. 15 are formed so as to engage with the lower surface of the inward flange-shaped wall 14. The outward flange 16 is not always necessary, and FIGS. 3a and 3b show an example of this case.

"Effect of device" The present invention is configured as described above, and the screw cylinder 3 is moved upward from the middle cylinder 2.
The upper part is erected, and the screw cylinder 3 above the middle cylinder 2 has a large inner diameter part. The inner peripheral edge of the inward flange-shaped wall 14 attached to the upper end of the large inner diameter part and the upper outer surface of the middle plate 5 form the middle plate. 5, the lower part of the mold cover 11 that fits on the outer surface of the upper part of the mold is sandwiched, and a plurality of engaging projections 15 ... Attached to the lower end of the outer surface of the mold cover are engaged with the lower surface of the inward flange-shaped wall 14, so that the mold is filled when the cosmetic is filled. Case 11
The rod-shaped cosmetic product can be molded without any trouble, and the screw cylinder 3 above the middle cylinder 2 can be used as a large inner diameter portion to prevent the screw from becoming loose or wobbling.
Since the space for fitting the lower part of the mold cover 11 is formed between the inner surface of the upper part of the upper part and the outer surface of the upper part of the inner plate 5, for example, the upper part of the inner plate 5 serves as a small outer diameter part and the inner surface of the upper part of the screw cylinder 3 As in the case of forming a space for fitting the lower part of the mold cover 11 with the upper outer surface of the plate 5, the mold cover fitted on the outer surface of the middle plate has a small inner diameter and is molded by the mold cover. There is no inconvenience that the stick-shaped cosmetic product has a significantly smaller diameter than the outer diameter of the storage container.
