TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dispensing container for storing a stick-shaped cosmetic such as a lipstick so as to be able to be dispensed and dispensed.
[0002]
[Prior art]
The dispensing container for accommodating stick-shaped cosmetics such as lipstick and stick foundation is constituted by combining a plurality of members, but since each component is assembled in a state that is difficult to separate, it is difficult to separate and discard. I was dissatisfied.
[0003]
In the case where the storage tube portion of the inner cylinder and the pan are used as a part of a stick-shaped cosmetic forming die, the entire feeding container is discarded due to a failure in forming the cosmetic. And it was difficult to reuse parts.
[0004]
As a conventional technique of a dispensing container that solves this dissatisfaction, a storage container such as a lipstick provided with a synthetic resin material inner cylinder member having a lower end inserted in a hakama member has an engagement hole at a substantially central portion of the bottom surface of the hakama member. And a locking piece which is engaged with the engagement hole so as to be non-rotatably and undetachably and can be disengaged by heating (e.g., substantially at the center of the bottom surface of the inner cylindrical member). And Patent Document 1.).

[Problems to be solved by the invention]
However, in the above-described prior art, the separation is achieved by utilizing the melting or deformation of the member by heating, so that it is difficult to reuse the member, and the effective use of the member cannot always be sufficiently achieved. was there.
[0007]
In addition, since the sorting of the members requires not only mechanical treatment but also heat treatment, the sorting process requires labor and dedicated equipment, and therefore, there is a problem that sorting costs are high. Was.
[0008]
In view of the above, the present invention has been made to solve the above-described problems in the related art. In a dispensing container capable of separating members, an inner body constituting a functional portion of the dispensing container, and handling of the dispensing container are described. A technology that locks and assembles an outer body constituting a holding portion with a mutually inserted assembling portion, and enables the locking and assembling to be released by reducing and bending deformation of the locking portion of the inner body. It is therefore an object of the present invention to eliminate the occurrence of permanent deformation of each member after separation and to easily achieve the separation process.
[0009]
[Means for Solving the Problems]
In the present invention for solving the above technical problems, the means of the invention described in claim 1 is:
Forming a cap mounting portion at the upper end, and having an outer body composed of an outer cylindrical body provided with a first locking function portion at the lower end of the inner peripheral surface,
A screw groove is formed on the inner peripheral surface, and a second locking function portion that locks with the first locking function portion of the exterior body is provided at a lower end portion of the outer peripheral surface, and a lower end provided with the second locking function portion A screw cylinder body that is configured to be elastically deformable by bending the portion inward, and is inserted and assembled non-rotatably in the outer cylinder body;
An inner cylinder body having an upper half as a storage cylinder part and a lower half as a guide cylinder part provided with a vertically long guide hole and rotatably inserted into a screw cylinder body;
A saucer body, which is inserted and assembled into the inner cylinder body so as to be able to ascend and descend while sliding, and at the lower end of the outer peripheral surface, is provided with a screwing pin which is threaded into a screw groove through a guide hole of the inner cylinder body,
Having an interior body consisting of
It is in.
[0010]
According to the first aspect of the present invention, an inner body in which an inner cylindrical body having a saucer body is inserted and assembled into a screw cylindrical body is inserted from below into an outer cylindrical body formed of an outer cylindrical body. The locking function part and the second locking function part are locked to achieve assembly of the feeding container.
[0011]
In a state where the exterior body and the interior body are assembled, the screw cylinder is fixedly attached to the outer cylinder, and the inner cylinder is pivotally attached to the outer cylinder.
[0012]
When the inner cylinder is relatively rotated with respect to the outer cylinder, the screw cylinder rotates together with the outer cylinder, so that the screw cylinder and the inner cylinder rotate relatively, and the pan body is displaced vertically. I do.
[0013]
In a state in which the tray body is positioned at the lower limit (see the right half of FIG. 1), the upper end opening of the storage cylinder portion of the inner cylinder body is closed with a lid serving as a mold, and the entire body is turned upside down. From the opening at the lower end of the screw body (bottom filling method), or by closing the lower end of the upper part of the saucer with a partition or the like, and setting the whole upright posture, from the opening at the upper end of the inner cylinder (top filling method) Then, the heated and melted cosmetic is poured until the liquid level reaches the upper part of the saucer body, and the solid is cooled and solidified, thereby simultaneously forming the cosmetic and assembling the cosmetic into the feeding container.
[0014]
When sorting the containers, the lower end portion of the screw body is bent and deformed in the radially-reducing direction, thereby displacing the second locking function portion inward with respect to the first locking function portion, whereby the second engagement function is performed. The locking of the stopping function portion to the first locking function portion is released.
[0015]
When the locking between the first locking function portion and the second locking function portion is released, the interior body is directly displaced downward with respect to the exterior body, and is pulled out from the exterior body and separated.
[0016]
In a state where the exterior body and the interior body are separated from each other, the interior body does not have a functional portion that prevents separation of the threaded body, the inner cylinder, and the saucer body, so that each can be easily separated.
[0017]
At the time of separation of these members, the only deformed lower end of the main body of the threaded cylinder returns to its original shape naturally when no external force is applied since the deformation is elastic deformation. It is separated without any permanent deformation while maintaining its original shape.
[0018]
According to a second aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the lower end portion of the screw body is bent inward and is elastically deformable, and the lower end portion is provided with an inner flange-shaped bottom flange piece. In addition, a short cylindrical inner cylinder piece is suspended from the lower end, and a split groove is provided at a lower end portion including the inner cylinder piece and the bottom flange piece.
[0019]
According to the second aspect of the present invention, by providing the split groove, the lower end portion of the screw body, that is, the lower end portion of the main body portion provided with the second locking function portion can be flexed elastically in the diameter reducing direction. Deformation is facilitated, and by providing the inner cylinder piece in a hanging shape, it becomes easier to apply an external force for deforming the lower end portion of the threaded cylinder in the diameter reducing direction by using the inner cylinder piece.
[0020]
According to a third aspect of the present invention, in the configuration of the first or second aspect, the first locking function portion is configured by a combination of an adjacent locking circumferential groove and a locking circumferential groove, and the second locking function portion is provided with a second locking function. The locking function part is constituted by a combination of a locking projection that locks in the locking circumferential groove of the first locking function part and a locking groove that locks the locking ridge of the first locking function part. What we did.
[0021]
According to the third aspect of the present invention, since both the locking function portions are constituted by a combination of the locking streak structure and the locking groove structure, the interior body cannot be pulled out or pushed into the exterior body. Thus, the mutual assembling posture of the exterior body and the interior body can be stably and reliably held at an appropriate position.
[0022]
According to a fourth aspect of the present invention, in the configuration of the first, second, or third aspect, the outer peripheral surface of the inner cylinder piece of the threaded body is a tapered surface that is a tapered surface that expands upward, and a lower end of the inclined surface The difference between the diameters of the upper and lower ends is set to a value larger than twice the locking depth of the both locking functional portions.
[0023]
According to the fourth aspect of the present invention, the cylindrical disassembly jig having the inner diameter equal to the outer diameter at the lower end of the slope of the inner cylinder piece is forcibly pushed up to the upper end of the slope of the inner cylinder piece to remove the jig. Only by fitting and fitting, the inner cylinder piece, that is, the lower end portion of the main body portion is surely reduced in diameter until the locking of both locking function portions is released.
[0024]
Also, in the state where the inner cylinder piece is reduced in diameter, since the assembling force of the disassembly jig with respect to the inner cylinder piece is relatively strong, by pulling back the disassembly jig as it is, the inner body is pulled out from the outer body. Separation is achieved.
[0025]
According to a fifth aspect of the present invention, in addition to the configuration of the first, second, third or fourth aspect, a plurality of split grooves are provided at equal intervals along a circumferential direction of the main body. It is.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The dispensing container according to the present invention comprises an exterior body 1 composed of an outer cylinder 2 and a sealing cylinder 12, an inner body 16 composed of a screw cylinder 17, an inner cylinder 29 and a tray 35, and a cap 38. It is configured.
[0028]
The outer cylinder 2 (refer to FIGS. 2 to 4 hereinafter) is formed by erecting a short cylindrical detachable cylindrical piece 10 reduced in diameter via a step 9 at the upper end of a main cylindrical body 3 having a linear cylindrical shape. At the upper end of the inner peripheral surface of the main body tube 3, a plurality of vertical ridges 8 for attaching the seal cylinder 12 and an assembling peripheral groove 7 are provided. At the center of the peripheral surface, a number of locking vertical stripes 4 are provided in the form of knurls, and at the lower end of the inner peripheral surface, a first locking function comprising a locking circumferential groove 5 and a locking circumferential strip 6. The part a is formed.
[0029]
The attaching / detaching cylindrical piece 10 for providing the attaching / detaching portion of the cap 38 has an outer peripheral surface having a regular polygonal shape (particularly, see FIG. 3), and an appropriate number (three in the illustrated embodiment) is provided on the outer peripheral surface. By providing the pressing protruding piece 11, the cap 38 is fitted with an external fitting so as not to be displaceable in rotation.
[0030]
The seal cylinder 12 (see FIG. 5) is a short cylindrical body made of a soft elastic material, and has on its outer peripheral surface a number of knurled vertical stripes 14 which are engaged with the engagement stripes 8 of the outer cylinder 2. At the lower end of the outer peripheral surface, an assembling peripheral line 13 is provided to engage with the assembling peripheral groove 7 of the outer cylindrical body 2, and at the upper end of the inner peripheral surface, a sealing peripheral line 15 is provided. At the same time, the outer peripheral body 13 is engaged with the assembling peripheral groove 7 so as to be immovably assembled in the outer cylinder 2.
[0031]
The threaded cylindrical body 17 (hereinafter referred to as FIGS. 6 to 8) constituting the inner body 16 has two thread grooves 19 engraved on the inner peripheral surface of a linear cylindrical main body 18. A plurality of vertical ridges 20 are provided on the outer peripheral surface to be locked to the locking vertical ridges 4 of the outer cylindrical body 2, and the lower end of the main body 18 is configured as an assembly part 22.
[0032]
The assembling portion 22 is formed on the outer peripheral surface thereof, that is, on the lower end portion of the outer peripheral surface of the main body 18, by a second engaging portion 23 and an engaging concave groove 24 which are engaged with the first engaging function portion a. In addition to forming the stop function part b, a short cylindrical inner cylinder piece 26 is continuously provided via an inner flange-shaped bottom flange piece 25, and a plurality of pieces including the bottom flange piece 25 and the inner cylinder piece 26 are provided. (In the case of the illustrated embodiment, two split grooves 28 are provided).
[0033]
The outer peripheral surface of the inner cylindrical piece 26 constituting the assembled portion 22 is a tapered inclined surface 27 whose diameter is increased upward, and the inclined surface 27 is defined by the diameter of the lower end and the diameter of the upper end. The height and the inclination angle are set such that the difference is at least twice the locking depth of the locking function portions a and b.
[0034]
The inner cylindrical body 29 (see FIG. 9), which is a constituent member of the interior body 16, is entirely formed of metal (may be formed of synthetic resin), and provides a molding surface of the cosmetic K. At the same time, the lower end of the linear cylindrical storage tube portion 30 for storing the cosmetic material K is provided over a substantially entire height range through a locking projection 34 which is curved and formed so as to protrude outward. The guide tube portion 31 having the guide hole 32 is provided in a hanging manner.
[0035]
The guide hole 32 of the inner cylinder 29 has a split groove shape that reaches the lower end edge of the guide cylinder portion 31, thereby enabling the insertion and assembly of the tray 35. At the lower end of the guide hole 32, a protrusion 33 is formed at the lower end of the guide hole 32 to prevent the slip-out pin 36 of the pan 35 from coming out at the lower end of the guide hole 32.
[0036]
In addition, since the seal rim 15 of the seal cylinder 12 is in close sliding contact with the outer peripheral surface of the storage portion 30, it is necessary to provide an appropriate resistance to the turning operation of the inner cylinder 29 with respect to the screw cylinder 17. Accordingly, a favorable feeling of use can be given to the dispensing operation of the cosmetic K.
[0037]
A pan 35 (hereinafter, referred to as FIGS. 10 and 11) which is a constituent member of the inner body 16 is provided at the lower end of the outer peripheral surface of a linear cylindrical body which is inserted into the inner cylindrical body 29 so as to be slidable up and down. A pair of screw pins 36 are provided to project through the guide holes 32 of the body 29 and screw into the screw grooves 19 of the screw cylinder 17.

The cap 38 (see FIG. 1) having a cylindrical shape with a top has an inner peripheral surface of the lower end opening formed in the same regular polygonal shape as the outer peripheral surface of the detachable cylindrical piece 10 of the outer cylindrical body 2. And a sealing cylinder piece 39 having a cylindrical shape with a top, which is tightly fitted to the storage cylinder portion 30 of the inner cylinder body 29, is internally fixed.
[0039]
As described above, since the sealing cylinder piece 39 is closely fitted to the inner cylinder body 29, if the cap 38 is assembled to the outer cylinder body 2 so as to be able to idle, the cap 38 is assembled, A relative rotation occurs between the outer cylindrical body 2 and the inner cylindrical body 29, whereby the stored cosmetic K is unjustly fed out, and a “topping” accident in which the tip of the cosmetic K strikes the cap 38 is caused. However, since the cap 38 is non-slidably assembled to the outer cylinder 2, there is no possibility that such an accident will occur.
[0040]
FIGS. 12 and 13 are for explaining the separation between the exterior body 1 and the interior body 16, and as shown in FIG. 12, a cylinder having an inner diameter dimension equal to the diameter dimension of the lower end of the slope 27 of the inner cylinder piece 26. When the detaching jig M having the shape is pushed up and forcibly fitted to the inner cylinder piece 26, the assembled portion 22 in which the split groove 28 is formed is bent in the diameter-reducing direction and elastically deformed (in FIG. (Shown by a two-dot chain line), so that the locking of the first locking function part a and the second locking function part b is released.
[0041]
When the dismounting jig M is pulled down from this state, the inner body 16 in a state of being fitted and held on the dismounting jig M comes out of the outer body 1 and is separated as shown in FIG. .

[0043]
Further, by providing a straight portion at the upper end of the outer peripheral surface of the inner cylinder piece 26, the contact area between the disassembly jig M and the inner cylinder piece 26 is increased, and the separation of the exterior body 1 and the interior body 16 is achieved. Can be made easier.
[0044]
In addition, the window hole 21 opened at the upper end of the screw body 17 and the open hole 37 opened at the upper part of the saucer 35 are used when the interior body 16 is used as a molding frame of the cosmetic K. The cooling power for cooling and solidifying the molten cosmetic that has been injected into the container is to efficiently and appropriately act.
[0045]
Although the above-described embodiment is directed to a dispensing container storing lipstick, it goes without saying that any container can be selected as a storage item as long as it can be used as a dispensing container, such as a stick glue or a brush.
[0046]
In the illustrated embodiment, the bottom filling method of the molten cosmetic is described as an example, but it goes without saying that the top filling method can be applied to the present invention.
