Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a bar-shaped solid cosmetic container for lipstick, eye shadow, eyeliner, etc.

(Prior art) Conventionally, this type of cosmetic container is used by making the cosmetic material appear and disappear from the tip of the container using a feeding mechanism. Even after the cosmetics were used, a large amount of cosmetics remained in the press cylinder, resulting in a lot of waste. In order to reduce the amount of residual core in this cosmetic,
Publication No. 30110 discloses that a push-out member is erected at the bottom of a rotating base, and the cosmetic storage tube is returned to reach the bottom of the rotating base, so that the push-out member is inserted into the cosmetic storage tube and cosmetics are dispensed. A structure that reduces the amount of cosmetic material remaining in the extruded cosmetic container is disclosed.

(Problem to be solved by the invention) However, with the above-mentioned prior art, there is a risk that the cosmetics storage cylinder may be returned too far to the bottom of the rotating base due to a mistake in the cosmetic delivery operation, and the cosmetics may be pushed out by the pushing member. This has the disadvantage that cosmetics that do not last long after use become unstable.

Therefore, in view of the above problems, this idea was developed by
This problem has been solved, and during normal feeding operations, the base of the long cosmetic is securely held in the deep holding part of the holding cylinder without wobbling, and when the cosmetic becomes short, the extrusion member can be easily moved. To obtain an inexpensive cosmetic container which is robust and does not malfunction, allowing cosmetics to be used without waste by extruding the cosmetics by a precise extrusion operation.

(Means for Solving the Problems) As a means to achieve this, this invention forms a cosmetic holding part in a holding cylinder into which the cosmetic goes in and out from the tip of the container by a feeding mechanism, and In addition to loading the cosmetic, a cut groove and a locking hole are formed in the holding cylinder at the rear of the cosmetic, a push cylinder with a pin is inserted into this, and the cosmetic is extruded from the rear end hole of the container by external operation. By pushing up the parts,
The amount of cosmetic material remaining in the cosmetic material holding portion of the holding tube is exposed in stages.

(Example) An example of a specific configuration of this invention shown in the drawings will be described in detail below.

1 and 2 show an embodiment of this invention, in which a slide tube 63 having a slide groove 64 therein is rotatably fitted into a screw tube 61 having a screw groove 62, and the tip thereof is connected to the screw tube 61 having a screw groove 62. 61, and the annular protrusion 65 at the rear end is fitted between the stepped portion 61a of the threaded cylinder 61 and the tail plug 66, so that the slide cylinder 63 is immovably mounted in the axial direction. A pipe-shaped holding cylinder 67 is fitted into the slide cylinder 63, and the protrusion 68 at the rear end passes through the slide groove 64 and fits into the thread groove 62, and the slide groove 64, the thread groove 62, and the protrusion 68 are inserted into the slide cylinder 63. The holding cylinder 67 constitutes a feeding mechanism that moves back and forth within the slide cylinder 63. The holding cylinder 67 has an inner surface as a cosmetic holding part 69, a ring-shaped step 70 protruding from the tip end, and a rib 71 formed on the tip side. Further, in the latter half, cut grooves 72 are bored from the rear end at intervals of 180 degrees in the circumferential direction, and circular locking holes 73 are formed in the cut grooves 72 at intervals. In addition, in the example, those formed at the front, rear, and center portions are shown. The holding tube 67 is filled with cosmetic A through the filling hole 74 of the tail plug 66, and the base of the holding tube 67 is attached to the holding part 69 so as to protrude longer than the tip. Furthermore, the holding cylinder 6
7, after filling cosmetic A, an umbrella-shaped flexible body 7 is inserted from the rear end.
The cut groove 7 is fitted with a bottomed cylindrical push tube 76 which is an extruded portion with a tip 5 attached, and a pin 77 protruding from the rear end of the push tube 76 is formed in the holding tube 67.
2, expand it and lock it in the locking hole 73 at the rear. Note that a bottom plate may be attached to the rear end of the push tube 76.

As a result, when the cosmetic A is long, the screw tube 61
By the rotation of the slide tube 63, the cosmetic A attached to the holding tube 67 is moved out and out of the slide tube 63 for use. When the amount of cosmetic A is reduced to the tip of the holding tube 67, insert a stick B etc. into the filling hole 74 of the tail plug 66 and press the push tube 76 with the tip of the stick. 75 is cosmetics A
When it comes into contact with the rear end and is further pushed up, the pin 77 of the pusher cylinder 76 separates from the locking hole 73 at the rear, expands the cut groove 72 and moves forward, and the pin 77 enters the locking hole 73 at the center. 77 is locked and stopped. As a result, the remaining core portion of the cosmetic A is exposed from the tip of the holding cylinder 67 and becomes ready for use again. Furthermore, when the extruded cosmetic A is reduced to the tip of the holding cylinder 67,
Press the push tube 76 again with the rod B. As a result, the pin 77 of the pusher cylinder 76 leaves the locking hole 73 in the center, moves forward in the cut groove 72, fits into the locking hole 73 in the front part, and stops. The remaining core amount is further extruded and exposed, so that it can be used again. In the case of this embodiment, since the pins 77 of the pushing tube 76 fit into the locking holes 73 provided at several places in the cut groove 72, the cosmetic A is ensured to the end without being pushed out too much by the holding tube 67 and falling out. can be used.

Note that the caps are removably fitted into the various cosmetic containers described above, as in the past.

(Effects of the invention) As described above in detail with respect to the embodiments, this invention can reliably hold the cosmetic without wobbling by the holding portion of the holding cylinder when the cosmetic is in a long state. In addition, when the amount of cosmetics decreases and reaches the tip of the holding tube, the extrusion member is pushed up to expose the remaining core of the cosmetics held in the holding section from the tip of the holding tube, making it possible to use more cosmetics. Therefore, cosmetics can be used without wasting them. Furthermore, the extrusion member that extrudes the cosmetics is inside the container, and the cosmetics cannot be extruded unless a rod or the like is inserted from the rear end of the container. When carrying the cosmetic product, the cosmetic container is simple and movable, extremely convenient to use, robust, easy to manufacture, and inexpensive.
