Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an extruded container for storing solid contents such as cosmetics (lipstick) and hair dye.

<Prior art> Conventional storage containers for lipsticks, hair styling products, solid hair dyes, etc. are bar-shaped cosmetic storage containers in which a required amount of stored solid contents is pushed out to the tip by rotating a knob. There is Publication No. 53-3896.

The structure of the above-mentioned cosmetics storage container includes an inner cylinder that slidably holds an extrusion inner plate fixed to the base end of the bar-shaped cosmetic (solid content), and an inner cylinder that extends from the base end of the inner cylinder to the inner plate. An extruded screw rod is screwed through the center of the rod, and a center hole into which the screw rod is inserted is formed in the center of the rod-shaped cosmetic, and when the rod-shaped cosmetic is stored in the inner cylinder, The screw rod is inserted into the center hole of the cosmetic bar, and in order to push out the cosmetic bar, the rotating tube provided at the base end of the screw rod is rotated. is configured to protrude from the tip of the inner cylinder together with the inner plate.

<Problems to be solved by the invention> However, in the above conventional example, it is impossible to push out the stored bar-shaped cosmetics with one hand, and one hand holds the container body and the other hand pushes out the bar-shaped cosmetics. The rotating barrel at the outer end of the screw rod that operates the cosmetics must be operated. Furthermore, since the threaded rod passes through the inner plate and enters the center of the bar-shaped cosmetic product, the bar-shaped cosmetic product requires a center hole to receive it, which increases the number of processing steps.

Further, if the contact between the inner plate and the inner cylindrical surface that guides the inner plate is unstable, there is a drawback that the bar-shaped cosmetic does not move smoothly in and out.

Therefore, the present invention addresses the above-mentioned drawbacks and aims to provide a push-out container that can be smoothly moved in and out with one hand without using any rotational movement.

<Means for solving the problem> An outer cylinder having a guide and holding ring for solid contents fitted at the tip, an inclined sheath tube that slides back and forth within the outer cylinder, and an inner tube inside the inclined sheath tube. It consists of a gripping body that is in contact with the holding body, a holding body that is inscribed in the gripping body and pushes out the solid contents from the holding ring, and a pressing spring that is elastically inserted between the outer cylinder and the gripping body.

<Function> By pushing the rear end of the gripping body against the outer cylinder against the pressure spring, the gripping body narrowed by the inclined sheath tube can release the solid inside the gripping body together with the inclined sheath tube. It moves forward while holding the holder at the proximal end of the contents, and in the middle of the forward movement, the forward movement of the inclined sheath tube is prevented, thereby relaxing the frictional connection between the gripping body and the inclined sheath tube. and,
The clamping action of the gripping body on the holding body is weakened, and the extrusion operation of the solid contents is stopped, and
It is frictionally held by a retaining ring at the tip. Here, by releasing the hand of the gripping body, the gripping body starts to move backward by the action of the compression spring while leaving the contents in that position, and the contents are inscribed in the inclined sheath tube and narrowed. It returns to its original state together with the sheath tube and is ready for the next operation.

<Embodiment> Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. An inward projecting edge 2 for receiving a spring is provided at one end of the outer cylinder 1, and a wide-diameter stepped portion is provided at the other end, that is, inside the tip. 4, and an inclined sheath tube 21 having a flange-shaped portion 22 on its outer periphery that is slidably fitted into the wide-diameter stepped portion 4 is press-fitted into the outer cylinder 1, and the inclined sheath The reduced end of the tube 21 is made to protrude beyond the side of the inward projecting edge 2 to be equal to the sliding length of the flanged portion 22, and a fourth tube is provided inside the inclined sheath tube 21.
As shown in the figure, the gripping body 13, which is divided into two or more parts in the longitudinal direction by the grooves 15, 15, is inserted.

The outer periphery of the gripping body 13 is such that when the flange 20 formed at its tip engages and abuts the tip flange 22 of the inclined sheath tube 21, it is inscribed along the inclination of the sheath tube 21. A large number of annular protrusions 17, 17... are arranged at equal intervals, and a spring receiving flange 18 is provided at the base end facing the inward protrusion 2 at a distance.
is provided protrudingly, a pressure spring 16 is inserted between the inward projecting edge 2 and the flange edge 18, and the gripping body 13 is configured to slide against the pressure spring 16. A bottom cover 14 is fitted to the outer end.

Further, a solid content 27 such as lipstick or a tick is inserted into the central part of the gripping body 13, with the base holder 23 fitted at the proximal end, that is, the inner end, and solid contents 27 such as lipstick or other ticks are inserted into the outer mantle 24 of the holder 23. A protrusion 26 is inscribed in the gripping body 13 to hold it.

The tip of the solid content 27 is frictionally held by the inner edge 7 of the retaining ring 5 fitted onto the tip of the wide-diameter stepped portion 4.

What is important in the above description is that a stopper step 9 is formed at the fitting portion of the retaining ring 5 and the wide-diameter step 4, and that a stopper step 9 is formed between the stopper step 9 and the flange-like portion 22 of the inclined sheath tube 21. It is to maintain a certain distance A necessary for operation,
Moreover, the end face of the outer mantle 19 of the bottom cover 14 and the outer cylinder 1
The distance B between the inward protruding edge and the inner surface of the gripping body 13 is approximately equal to the distance C between the flange 20 at the tip of the gripping body 13 and the inner surface of the retaining ring 5;
Both B and C are larger than A.

In addition, the reference numeral 6 in the figure is a mantle formed on the periphery of the retaining ring 5, and 8 is a protrusion provided on the outer periphery of the mantle 6.
The cap 10 is designed to elastically move over the inward protrusion 12 formed on the circumferential outer mantle 11 of the cap 10 to allow the cap to be attached and detached.
It is a protrusion having an annular or other arbitrary shape to enhance the bond so as not to separate from 3.

Next, to describe these series of operations, first, the cap 10 is removed and the bottom cover 14 is pushed in the direction of the arrow in FIG. A pressure spring 16 elastically interposed between the edge 18 and the inward protruding edge 2 constantly presses in the repelling direction, and as a result, the flange 20 provided at the tip of the gripping body 13 presses against the inclined sheath tube 21. It engages with a flange-shaped part 22 provided at the expanded end of the outer cylinder 1, and maintains stability when the flange-shaped part 22 is stopped by the inner end stepped part 3 formed in the wide diameter part 4 of the outer cylinder 1. In this state, the gripping body 13 has an annular protrusion 17,1 on the outer periphery.
7... is narrowed in the center direction in contact with the inner slope of the inclined sheath tube 21, thereby tightly internally sandwiching the protrusions 26, 26... of the holder 23 inside, and solid contents. 27 is held immobile in that position.

Then press the spring 16 to push the bottom cover 14 in the direction of the arrow in Figure 2.
When pushed against the
7, 17..., and first moves forward together with the gripping body 13 by the distance A, but during this period the gripping body 13 is in a constricted state due to the inclined sheath tube 21 and moves while holding the holding body 23 between them. The forward motion of the inclined sheath tube 21 is stopped when the brim 22 comes into contact with the stop step 9, and when the gripping body 13 is further pushed by the remaining distance C-A, the gripping body 13 is moved as follows. Since it is in slope contact with the inclined sheath pipe 21, it moves along the slope,
It expands outward by its own elasticity and releases the mantle 24 of the holding body 23 from the constricted state.

Therefore, when the gripping body 13 enters the operating range of the interval C-A, it becomes impossible to grip the holding body 24, and the solid contents 27 are frictionally held by the holding ring 5 at the tip. Combined with this, it becomes impossible to extrude the solid content 27.

In this way, the operation range for extruding the contents is the interval A in which the inclined sheath tube 21 can move forward, and after that, the surplus operation interval C-A is the operation for releasing the holding body 23 from the constricting operation of the gripping body 13. Become. As shown in FIG. 3, by releasing the bottom cover 14 when the tip of the gripping body 13 comes into contact with the retaining ring 5, the gripping body 13 is narrowed into an inclined sheath tube while the pressing spring 16
It immediately returns to its initial position (Fig. 1) with the elasticity of
Grasp and hold the holder 23 at the proximal end of the contents again.

In order to expose the solid contents 27 to the required length in this way, by repeatedly pressing the bottom cover 14,
The exposure amount a (a = A) in one operation is the limit, and it is used by pushing out a length corresponding to the number of times of pushing, but when not in use, to store the contents 27, press the bottom cover 14. The contents 27 can be easily stored by pressing the contents 27 into the gripping body 13 while the contents 27 remain in the gripping body 13. In addition, if the amount of exposure equivalent to one operation is sufficient, if the height from the outer surface of the retaining ring 5 to the top surface of the cap 10 is the same or higher, the contents can be stored after each use. It is possible to cover the cap 10 without having to do so. In addition, in the above, a large number of annular protrusions 17, 1 are provided on the outer periphery of the gripping body 13.
7... was shown, but this was done to reduce the amount of material and weight.
The shape is not limited to this, but the entire outer surface of the gripping body 13 may be an inclined surface along the inner surface of the inclined sheath tube 21, or several stripes may be formed along the longitudinal direction of the gripping body 13. A slanted protrusion is fine.

<Effects of the Invention> As described above, with the present invention, it is possible to easily extrude the required amount with only a light extrusion operation of the fingertip, and moreover, by repeated pressing operations with one hand.

In addition, in this way, the contents can be sequentially pushed out to the end using only a pushing operation.

Since the tip of the solid content is always frictionally held by the tip holding ring, even if the gripping force of the content by the gripping body becomes weak, it provides sufficient stability and prevents the tip from shaking. It also operates smoothly. Moreover, unlike extrusion by rotation, the cross section may be circular or prismatic, and the shape is not restricted. It is a highly practical idea with many excellent effects, such as the absence of a central hole in the contents, which makes it easy to mold, and at the same time allows a sufficient capacity to be maintained.
