Description

  The present invention belongs to the technical field of stick-shaped cosmetic containers for storing stick-shaped (stick-shaped) cosmetics such as lipsticks.

Generally, in this kind of bar-shaped cosmetic container, a thick part is formed on an inner cap fitted into the cap, and the thick part is covered from the position immediately before the cap completely covers the upper end of the container body. A member was proposed in which resistance was imparted by climbing over the convex ribs formed on the member so that the cap was in a fully covered state (Patent Document 1).
Japanese Patent No. 3153992

  However, in the conventional cover, the inner cap is fitted in a loosely fitted state with a gap with respect to the upper end member of the cap until the position immediately before the entire cover in the covering process. There is a problem that there is a sense of stability and a sense of luxury is inevitably lacking.

The present invention was created with the object of solving these problems in view of the above circumstances, and the invention of claim 1 is externally fitted to the upper end member of the container body in which the bar-shaped cosmetic is accommodated. Then, in the stick-shaped cosmetic container constructed by incorporating the inner cap inside the cap for covering the container body, the upper end member of the container body is formed by a convex rib formed so as to protrude from the outer peripheral surface. Also, the extended end portion is provided with an extended end portion, and the extended end portion is in sliding contact with the inner cap during the process from the midway position where the cap is covered through the immediately preceding position until the cover is fully covered. Thus, the convex portion protruding from the inner peripheral surface to deform to the outer diameter side to give the first movement resistance, and the convex ribs get over in the process of completely covering from the position immediately before the cap completely covers the first One move It is shaped cosmetic material container, characterized in that the ridge that protrudes from the outer peripheral surface to the second to the grant transfer resistance is formed larger than.
The invention according to claim 2 is the stick-shaped cosmetic container according to claim 1, characterized in that a plurality of convex portions formed in the inner cap are formed in the circumferential direction in a plurality of linear shapes that are long in the vertical direction. is there.
In the invention of claim 3, the convex portion formed on the inner cap protrudes toward the inner peripheral surface side, and the outer peripheral surface side is formed with a horizontal cross-section> shape or bowl shape extending in the vertical direction, and the extended end portion The rod-shaped cosmetic container according to claim 1 or 2, wherein the first resistance is generated by deforming to the outer diameter side by pressing.

According to the first aspect of the present invention, a first movement resistance smaller than the second movement resistance in the final process is generated in the stage before the process from the position immediately before the cap completely covers to the time when the cap is completely covered. As a result, a sense of stability increases in the cover operation of the cap, and a high-class feeling is generated.
According to the invention of claim 2, the first movement resistance can be imparted evenly in the circumferential direction for a long time, and the sense of stability is further increased.
By setting it as invention of Claim 3, a 1st movement resistance generate | occur | produces by the unreasonable deformation | transformation of an inner cap, and the more excellent sense of stability can be exhibited.

Next, embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a tube main body, and a guide hole 1a is formed in the tube main body 1 along the longitudinal direction (vertical direction), and an accommodating portion 2a for accommodating a rod-shaped cosmetic material (not shown) is provided on the inside. An intermediate dish body 2 formed in the above is incorporated so as to be movable up and down.
Reference numeral 3 denotes a spiral cylinder body in which the cylinder main body 1 is incorporated, and the spiral cylinder body 3 is provided with a spiral spiral groove 3a on the inner peripheral surface. An engaging projection 2b projecting from the outer peripheral surface of the inner tray body 2 is engaged with the spiral groove 3a so as to move up and down while penetrating the guide hole 1a. When the cylinder body 3 is relatively rotated in the circumferential direction, the inner tray body 2 moves up and down (up and down) in a state where the rotation is restricted with respect to the cylinder body 1.

  In addition, a ring 3b that is externally fitted and fixed to the cylinder main body 1 is provided so as to be positioned on the upper side of the spiral cylindrical body 3, and the lower end portion of the middle tool 4 is externally fixed and fixed to the lower end portion of the ring 3b. In the middle tool 4, an upper end 4a extending upward from the upper end of the spiral cylindrical body 3 is fitted into a lower end of a cap 5 to be described later, and the upper end 4a is covered. An annular convex rib 4b is provided on the outer peripheral surface, extends further upward from the convex rib 4b, and protrudes upward from the extended upper end 4c in a state where the cylindrical body 1 has a small-diameter step shape. Reference numeral 6 denotes an eaves cylinder that is externally fitted and fixed to the inner tool 4 and the helical cylinder 3, and these members 1, 2, 3, 4, 6 constitute a container body X.

  On the other hand, a resin-made inner cap 7 in the shape of a cylinder is fixed to the cap 5 so as to prevent the inner cap 7 from coming off. The inner cap 7 has an outer peripheral surface with respect to the inner peripheral surface of the cap 5. The lower end 7a is a trumpet-shaped opening whose inner peripheral surface is expanded toward the lower end side so that the inner tool extending upper end 4c can be easily fitted. The lower end 7 b is in contact with the inner peripheral surface of the lower end portion of the cap 5. Incidentally, although the middle tool extension upper end 4c is configured to be bent inward in the present embodiment, it may of course be a straight shape without being bent.

Further, on the outer peripheral surface of the inner cap lower end portion 7a, there are formed first and second protruding ridges 7c and 7d that are annular with an interval in the vertical direction and are in contact with the inner peripheral surface of the cap 5. The portion between the first and second ridges 7 c and 7 d constitutes a thin portion 7 e that is thin with respect to the ridges 7 c and 7 d and is separated from the cap 5. When the cap 5 is covered (closed), the middle convex rib 4b is positioned at the lower part of the lower second ridge 7d in the state immediately before the full cover (see FIG. 3C). When the cap 5 is forcibly pushed further in this state, the cap 5 is in the fully closed position (see FIG. 3D). Then, the convex rib 4b gets over the second ridge 7d and is positioned between the first ridge 7c and the second ridge 7d, and elastically deforms the thin portion 7e toward the outer diameter side. The first ridges 7c and the second ridges 7d are pressed against the inner peripheral surface of the cap 5 by an elastic force, thereby ensuring double airtightness. When the fully closed position is reached, the lower end 5a of the cap 5 abuts against the annular convex portion 4d formed on the inner tool 4 so that it is pronounced “click” and the cap 5 is in the fully closed position. This can be confirmed by hearing.
Incidentally, in the present invention, it is not always necessary to exhibit the excellent airtightness as described above, and the present invention can be carried out even when there is no airtightness, and the intermediate tool 4 does not have the annular convex portion 4d. Of course, the cap lower end 5a may come into contact with the upper end 6a of the rod tube 6 to generate sound when fully covered.

  Further, on the inner peripheral surface of the inner cap 7, the convex rib 4 b reaches the second convex ridge 7 d on the lower side immediately before the full cover in the process of covering the cap 5 and receives the second movement resistance. In the middle stage before the process, a plurality of convex portions 7f are formed in the circumferential direction in which the middle tool extending upper end 4c comes into contact and becomes a movement resistance (corresponding to the first movement resistance of the present invention). Yes. In the present embodiment, the convex portion 7f protrudes toward the inner peripheral surface side of the inner cap 7, and is formed into a horizontal cross-sectionally-grooved groove shape (ridge shape) that is recessed on the outer peripheral surface side. ing. Incidentally, the convex portion 7f only needs to be the first movement resistance and is not limited to the horizontal cross-sectional shape, and may be, for example, a horizontal cross-section> shape, or more simply inward from the inner peripheral surface. It can be formed even with a thick wall projecting toward it.

  Then, in the process of covering the cap 5, the inner cap extension upper end 4c is changed from the state in which the inner cap 7 does not interfere with the middle tool 4 and there is no movement resistance (see FIG. 3A) to the inner cap convex portion 7f. The first movement resistance is generated by the contact (see FIGS. 3B and 4A), and when the cap 5 is pushed in a state against the first movement resistance, the convex portion 7f. Is elastically deformed to the outer diameter side within the gap S (see FIGS. 3C and 4B), and the cover operation is performed in a state where the first movement resistance is maintained. The second movement resistance described above occurs when the convex rib 4b reaches the second convex stripe 7d from the first convexity 7d, whereas the first movement resistance is the elastic deformation in the range of the gap S of the convex part 7f. The second movement resistance has no second protrusion 7d in contact with the inner peripheral surface of the cap 5. Since it is a resistance to overcome, it is larger than the first movement resistance. For this reason, in the process of covering the cap 5, a small first movement resistance is continuously generated through a process of free covering without resistance. After that, a large second movement resistance is instantaneously generated, and it is set so as to sound a snapping and cover the entire cover.

  In the embodiment of the present invention configured as described, when the container body X is covered with the cap 5, the inner cap 7 is fitted into the cap 5, and the second end is formed at the lower end of the inner cap 7. The protruding rib 7d is formed, and the protruding rib 4b forcibly climbs over the second protruding rib 7d at a position immediately before the entire covering, thereby generating a snapping sound in a state of receiving a large second movement resistance and covering the entire covering. However, in the cover process in the middle of the position immediately before the entire cover, as described above, the middle extension upper end 4c abuts against the inner cap protrusion 7f, and a small first movement resistance is generated. After the state of receiving the first movement resistance continues until reaching the position immediately before the full cover, the cover is fully covered by the second movement resistance.

  In the case where the present invention is implemented as described above, when the container body X is covered with the cap 5, after the first free state in which the movement resistance is not received, a small first movement resistance is received from the middle. The cover is covered in a closed state, and finally the cover is fully covered while sounding snapping in a state of receiving a large second movement resistance. As a result, the stability of the cover operation is increased, so that a cover with no instability can be obtained and a high-class feeling can be given.

  In addition, in this case, since the plurality of convex portions 7f formed on the inner cap 7 are formed at equal intervals in the circumferential direction to give the first movement resistance, the first movement resistance is unevenly distributed. As a result, stability is improved and operability is improved.

Furthermore, in this thing, the convex part 7f for giving a 1st movement resistance protrudes in the inner peripheral side with respect to the inner cap 7, and what has a bowl shape in the horizontal cross section which was immersed in the outer peripheral side is an up-down direction. Since it is formed long and this is pushed by the middle tool extending upper end 4c in the process of the cover operation and elastically deforms outward in the range of the gap S, it gives the first movement resistance. It becomes granted, and the stability is further increased.
In addition, this invention is not limited to the rod-shaped cosmetic container of the said embodiment, Of course, it can implement in the various stick-shaped cosmetic containers in the range which can implement this invention.

It is a longitudinal cross-sectional view which shows the state which the middle ingredient of the cosmetics container covered with the cap moved to the lowest end and the highest end position. (A) (B) is the front view and top view which carried out the partial longitudinal cross-section of the inner cap.
