Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a delivery container for accommodating cosmetics such as eye shadow, eye liner, lip liner, etc., which have a small diameter, are soft and contain a volatile component.

(Prior Art) Conventionally, there is a small-diameter, soft cosmetic material in which a holding body that holds the cosmetic material is moved forward and backward by a sliding shaft so that the cosmetic material is projected and retracted from the tip of the shaft, and a portion that stores the cosmetic material is a cartridge container, There has also been proposed one that can be easily detached from the shaft cylinder.

(Problems to be solved by the invention) However, in order to make small-diameter, soft cosmetics appear in and out of the container, the cosmetics are filled into the pipe, and then the push bar and the cosmetics gripping portion are interlocked to remove the cosmetics. Although it appears and disappears, if a product filled with cosmetics is put in and out, it may come out of the cosmetics gripping part due to the frictional resistance with the inner wall of the pipe, or it may break due to a strong pressing force. If a component is included, this emission may cause alteration. Therefore, the present invention is intended to improve the above-mentioned drawbacks of the prior art, and to provide a feeding container capable of smoothly appearing and retracting by preventing breakage and deterioration of a small-diameter, soft, volatile cosmetic material. .

(Means for Solving the Problem) Therefore, a pipe is airtightly inserted in a cartridge cylinder fitted and held at the tip of the shaft cylinder via a leaf spring, and the pipe contains a small-diameter, soft volatile component. A cosmetic is accommodated with a minute gap, and a screw cylinder having an internal thread engraved on the inner wall is fixed in the shaft cylinder, and a rotation stopping cylinder is rotatably inserted in the screw cylinder. A longitudinal knurl that engages with the knurl on the outer periphery of the rear portion of the cartridge cylinder is provided in the interior of the cartridge, and a vertical guide groove is provided, which is screwed into the female thread of the screw cylinder and is guided in the guide groove of the rotation stopping cylinder. The gripping piece of the gripping body that holds the rear end of the cosmetic material in the pipe is locked to the constricted part of the bulging part of the push rod tip that moves forward and backward, and this gripping body is provided with packing on the outer periphery to make the pipe airtight. The cartridge that slides and is detachably fitted to the rear cartridge A bush is fitted to the end of the cylinder.

(Operation) With the above configuration, when the cartridge cylinder is gripped and the shaft cylinder is rotated, the projection of the push rod that fits into the screw groove of the integral screw cylinder inside the shaft cylinder is pushed by the cartridge cylinder. The cosmetic that is housed in the pipe with a minute gap is advanced and retracted by being guided by the guide groove of the rotation stopping cylinder that is integrated with the cartridge cylinder through the knurl, and is further engaged with the constricted portion of the bulging portion at the tip of the push rod. Since the gripping piece of the gripping body moves back and forth in the pipe in an airtight manner, the cosmetic material accommodated in the pipe in the cartridge cylinder and the wall surface of the pipe can be smoothly retracted and retracted without resistance. However, there is no risk of breakage or deterioration.

(Example) This will be further described with reference to an example shown in the drawings. In (1), a screw cylinder (4) which is a shaft cylinder and has an internal thread (7) on its inner wall
The screw cylinder (4) is fitted with a knurl (11) in the longitudinal direction of the tip end (10), and a detent cylinder (5) having a vertical guide groove (6) is fixed in the screw cylinder (4). Insert it rotatably.

On the other hand, the cartridge tube (2) held by the inner tool (26) for fixing the leaf spring (27) in the shaft tube (1) has a knurl (12) engraved on the outer periphery of the rear end, and the cartridge tube ( When 2) is fitted into the shaft cylinder (1), it is locked to the knurl (11) of the rotation-stopping cylinder (5) to prevent rotation. A pipe (19) is airtightly inserted in the cartridge tube (2), and a small gap (20) is formed in the pipe (19).
It contains a soft cosmetic material (18) having a volatile component. A window hole (29) is provided on the rear end of the cosmetic (18) for solidifying the cosmetic (18).
The grasping body (13) integrated by (Fig. 2) is located, and the cosmetic (18) can slide airtightly along the inner wall of the pipe (19) by the advancement of the grasping body (13). There is.

The gripping body (13) has a plurality of elastic gripping pieces (15) at its rear end, and the end of the gripping piece (15) is provided with a protrusion (28) inside and outside, and in particular, this gripping piece (15). When is drawn into the pipe (19), the protrusion (28) and the inner wall of the pipe (19) come into contact with each other to engage with the constricted portion of the base of the bulging portion (16), so that the push rod (8) moves forward and backward. The material (18) can be retracted from the tip of the cartridge tube (2).

An inner plug (22) is fitted into the cap (3) through an inner lid (21) by being elasticized by a spring (23), and when the lid is closed, the tip of the cartridge cylinder (2) is elastically resilient. Seal tightly to ensure airtightness.

The cosmetic (18) is mounted in the pipe (19) which is hermetically inserted in the cartridge cylinder (2) as follows. That is, as shown in FIG. 3, first, a filling pipe (A) having a diameter (D) smaller than the inner diameter of the pipe (19) is prepared, and an annular rubber packing (14) is attached to the holding cylinder (13). Insert it on top and pour in the molten cosmetic (18) from the other end. Furthermore, as shown in FIG. 4, a filling pipe (A) in which the rear end of the cartridge tube (2) is attached to one of the through holes of the jig (C) and the cosmetic material (18) is filled in the other end. Of the push rod (B) with the same shape as the push rod (8) from the rear end.
Is fitted and extruded into the gripping piece (15) of the gripping body (13),
Since the diameter of the filling pipe (A) is slightly smaller than the diameter (D ') of the pipe (19), the cosmetic (18) having a slightly smaller diameter will be loaded into the pipe (19). . In addition, by making the filling pipe (A) slightly longer than the length of the pipe (19), when the cartridge is inserted into the cartridge barrel (2), the tip portion (1) in which a nest is particularly generated at the tip portion of the cosmetic is generated. Since it can be removed together with the concave part of the sink mark, it is possible to put on good quality cosmetics. (24) is a spring, which is inserted between the rear end of the screw cylinder (4) and the stopper (25) of the rotation stop cylinder (5) to fix the rotation stop cylinder (5) and the screw cylinder (4). , (30) are bushes fitted to prevent the gripping body (13) from falling off from the rear end of the cartridge tube (2). Since this embodiment is configured as described above, the cap (3) is removed, and the cartridge tube (2) is attached to the shaft tube (1) via the inner tool (26) and the leaf spring (27). The tip of the push rod (8) is gripped by the gripping piece (15), and the knurl (12) of the cartridge cylinder (2) is fixed to the rotation stopping cylinder (5).
When the cartridge cylinder (2) and the shaft cylinder (1) are relatively rotated after being locked with the knurl (11) on the inner circumference of the tip end, the screw cylinder (4) is rotated together with the shaft cylinder (1), The protrusion (9) of the push rod (8) fitted in the thread groove (7) of the screw cylinder (4) is locked integrally with the cartridge cylinder (2).
Since it is constrained in the guide groove (6), it advances along the guide groove (6) without rotating, and the grip body (13) is integrated with the push rod (8) by the grip piece (15). Moves forward integrally with the rear end of the cosmetic (18), and the cosmetic (18) can smoothly project from the inside of the pipe (19). The cosmetic (18) only has a slight gap with the pipe (19), which eliminates frictional resistance, and the volatile components in the cosmetic (18) are saturated in the gap and the amount of emission is very small. Stopped,
In addition, airtightness is maintained before and after the cosmetic (18),
Since the pipe (19) is also airtightly inserted in the cartridge tube (2), it maintains high airtightness, so that breakage and deterioration of the cosmetic material in the pipe can be prevented. Moreover, as described above, the gripping body and the cosmetic are integrated, and the gripping body and the push rod are also integrated, so that it is easy for the cosmetic to come in and out of the pipe due to the forward and backward movement of the push rod. It is also possible to prevent breakage of various cosmetics.

(Effect of device) As described above, since the device of the present invention accommodates the cosmetic material that is thin and soft and may be broken with a minute gap in the pipe, the container of the cosmetic material can be smoothly moved in and out. Since it can be held in a cartridge type so that it can be freely exchanged, it is possible to obtain a cosmetic material with good adhesiveness during makeup, and by using a pipe, the airtightness of the cosmetic material can be increased, and the gripping piece and the tip of the push rod can be engaged. Can be reliably performed by the rear edge of the pipe, and by using the filling pipe and the push rod, it has an excellent effect that the filling work of the cosmetic material is facilitated by the fitting and releasing of the gripping piece of the gripping piece.
