Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding container for storing stick-shaped cosmetics such as lipsticks so that they can be drawn out and fed in.
[0002]
[Prior art]
Although the feeding container for storing stick-shaped cosmetics such as lipstick and stick foundation is composed of a plurality of members, each component is assembled in a state where it is difficult to separate, so it is difficult to separate and dispose of it. I was dissatisfied.
[0003]
In addition, in the case where the storage cylinder part and the tray body of the inner cylinder are used as part of the mold for the bar-shaped cosmetic product, the entire delivery container is discarded due to a failure in molding the cosmetic. There was a complaint that it was difficult to reuse parts.
[0004]
As a conventional technique of a feeding container that eliminates this dissatisfaction, in a storage container such as a lipstick provided with an inner cylindrical member made of a synthetic resin material in which a lower end portion is inserted into a hook member, an engagement hole is formed at the substantially central portion of the bottom surface of the hook member. Is formed at the substantially central portion of the bottom surface of the inner cylinder member with an engagement hole and a locking piece that is non-rotatable and non-detachable and can be disengaged by heating (for example, , See Patent Document 1).

[Problems to be solved by the invention]
However, in the above-described prior art, since the separation is achieved by utilizing melting or deformation by heating the member, 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 not only mechanical treatment but also heat treatment is required for the separation of parts, it requires labor and dedicated equipment for the separation treatment. It was.
[0008]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and in the feeding container that enables the separation of the members, the inner body constituting the functional part of the feeding container, and the handling of the feeding container The exterior body constituting the holding portion is locked and assembled at the portion with the mutual insertion assembly, and the engagement with the locking assembly can be released by the reduced diameter bending deformation of the locking portion of the interior body. Accordingly, it is an object of the present invention to eliminate the permanent deformation of each member after sorting, and to easily achieve the sorting process.
[0009]
[Means for Solving the Problems]
Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
A cap mounting part is formed at the upper end, and an exterior body composed of an outer cylindrical body provided with a first locking function part at the lower end of the inner peripheral surface;
A lower end provided with a second locking function part, which is provided with a second locking function part for locking with a first locking function part of the exterior body at the lower end part of the outer peripheral surface. A screw cylinder body configured to bend inward and be elastically deformable, and to be inserted into the outer cylinder so as not to rotate,
An inner cylinder body having a storage cylinder part in the upper half and a guide cylinder part in which the lower half is provided with a vertically long guide hole and is rotatably inserted into the screw cylinder body,
In this inner cylindrical body, an insertion assembly is attached so that it can be moved up and down while sliding, and a tray body that protrudes from the lower end portion of the outer peripheral surface through a guide hole of the inner cylindrical body and screwed into a screw groove,
Having an interior body consisting of,
A configuration in which the lower end portion of the screw body is bent inward and can be elastically deformed, and a short cylindrical inner cylinder piece is suspended from the lower end portion via an inner hook-shaped bottom rod piece. It was supposed to have a split groove at the lower end including the bottom piece,
It is in.
[0010]
According to the first aspect of the present invention, an interior body in which an inner cylinder body in which a tray body is housed is assembled and inserted into a threaded cylinder body is inserted from below with respect to an exterior body composed of an outer cylinder body. The latching function part and the second latching function part are latched to achieve assembly of the feeding container.
[0011]
In a state where the exterior body and the interior body are assembled, the screw cylinder body is fixedly assembled to the outer cylinder body, and the inner cylinder body is rotatably assembled to the outer cylinder body.
[0012]
When the inner cylinder body is rotated relative to the outer cylinder body, the screw cylinder body rotates together with the outer cylinder body, so that the screw cylinder body and the inner cylinder body rotate relative to each other, and the tray body is displaced up and down. To do.
[0013]
In a state where 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 that is a mold frame, and the whole is inverted. From the lower end open part of the screw cylinder (bottom filling method), or from the upper end open part of the inner cylinder (upper filling method) with the lower end of the upper part of the saucer body closed with a partition wall etc. The hot melt cosmetic is poured until the liquid level reaches the upper part of the saucer body, and this is cooled and solidified to simultaneously form the cosmetic and attach it to the feeding container.
[0014]
When separating the containers, the second locking function portion is displaced inward with respect to the first locking function portion by bending and deforming the lower end portion of the screw cylinder body in the direction of diameter reduction, and thereby the second engagement portion. The locking of the locking function portion with respect to the first locking function portion is released.
[0015]
If the locking between the first locking function portion and the second locking function portion is released, the interior body is moved downward with respect to the exterior body as it is, and is pulled out and separated from the exterior body.
[0016]
In a state where the exterior body and the interior body are separated, the interior body does not have a functional portion that prevents separation of the screw cylinder body, the inner cylinder body, and the saucer body, so that each can be easily separated.
[0017]
At the time of the separation of each member, the only deformation of the lower end portion of the main body of the screw cylinder is elastic deformation, so that when the external force is lost, it naturally returns to its original shape. Thus, separation is performed while maintaining the original shape without causing permanent deformation.
[0019]
Furthermore , by providing the split groove, the elastic deformation of the lower end portion of the screw cylinder body, that is, the lower end portion of the main body portion provided with the second locking function portion in the reduced diameter direction is facilitated. By providing it in a hanging shape, it becomes easy to apply an external force for deforming the lower end portion of the screw cylinder body in the diameter-reducing direction using this inner cylinder piece.
[0020]
According to a second aspect of the invention, the configuration of the invention of claim 1 Symbol placement, the first locking function unit, as well as a combination of the adjacent locking circumferential groove and the engaging circumferential strip, the second locking The functional part is configured by a combination of a locking protrusion that is locked to the locking circumferential groove of the first locking function part and a locking groove that is locked by the locking circumferential line of the first locking function part. That is,
[0021]
In the invention according to claim 2 , since both the locking function portions are configured by a combination of the locking strip structure and the locking groove structure, the interior body cannot be pulled out and pushed into the exterior body. As a result, the posture of mutual assembly of the exterior body and the interior body is stably and reliably held at an appropriate position.
[0022]
According to a third aspect of the invention, the configuration of the invention of claim 1 or 2, wherein the outer peripheral surface of the inner cylinder piece threaded cylindrical body, a slope is a tapered surface whose diameter increases upwards, the lower end of the slope And the difference in diameter between the upper end and the upper end is set to a value larger than twice the locking depth of both locking function portions.
[0023]
In the invention according to claim 3, the cylindrical assembly jig having an 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 outer cylinder. By simply fitting and fitting, the inner cylinder piece, that is, the lower end portion of the main body portion, is reliably reduced in diameter until the locking of both locking function portions is released.
[0024]
Also, when the inner cylinder piece is deformed in a reduced diameter, the assembling force of the assembling jig with respect to the inner cylinder piece is relatively strong. By pulling the assembling jig as it is, the inner body can be pulled out from the outer body. Separation is achieved.
[0025]
Those invention of claim 4, in which the structure of claim 1, 2 or from 3 described invention, the split groove, providing the plurality at equal intervals along the circumferential direction of the main body, was added It is.
[0026]
In this invention of Claim 4, it becomes easy to cause the elastic bending deformation to the diameter reduction direction of the lower end part of the main-body part of a screw cylinder body including an inner cylinder piece by providing several split grooves.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The feeding container according to the present invention includes an exterior body 1 composed of an outer tubular body 2 and a seal tubular body 12, an interior body 16 composed of a screw tubular body 17, an inner tubular body 29, and a tray body 35, and a cap 38. It is configured.
[0028]
The outer cylindrical body 2 (refer to FIG. 2 to FIG. 4 below) has a short cylindrical detachable cylindrical piece 10 that is reduced in diameter via a step portion 9 erected at the upper end of a body cylinder 3 having a linear cylindrical shape. The upper end of the inner circumferential surface of the main body cylinder 3 is provided with a plurality of vertical strip-like locking strips 8 and assembly circumferential grooves 7 for assembling the seal cylinder 12. A number of locking vertical stripes 4 are provided in a knurled shape at the center of the circumferential surface, and a first locking function comprising a locking circumferential groove 5 and a locking circumferential stripe 6 at the lower end of the inner circumferential surface. Part a is formed.
[0029]
The outer peripheral surface of the removable cylindrical piece 10 that provides the removable portion of the cap 38 has a regular polygonal shape (in particular, see FIG. 3), and an appropriate number (three in the illustrated embodiment) is provided on the outer peripheral surface. By providing the pressing protrusion 11, the cap 38 is fitted with an external fitting assembly so that it cannot be displaced.
[0030]
The seal cylinder 12 (see FIG. 5) is a short cylindrical body made of a soft elastic material, and is provided with a large number of knurled vertical stripes 14 to be engaged with the engagement stripes 8 of the outer cylinder 2 on the outer peripheral surface. An assembled peripheral strip 13 is provided at the lower end of the outer peripheral surface to be engaged with the assembled peripheral groove 7 of the outer cylindrical body 2, and a seal peripheral strip 15 is provided at the upper end of the inner peripheral surface. 14 is latched, and the assembled circumferential groove 13 is engaged with the assembled circumferential groove 7 so as to be immovably assembled in the outer cylindrical body 2.
[0031]
The screw body 17 (refer to FIG. 6 to FIG. 8 below) constituting the inner body 16 has two thread grooves 19 formed on the inner peripheral surface of the linear cylindrical main body portion 18. A plurality of vertical protrusions 20 that are engaged with the engagement vertical stripes 4 of the outer cylindrical body 2 are provided on the outer peripheral surface, and the lower end portion of the main body portion 18 is configured as an assembly portion 22.
[0032]
The assembled portion 22 has a second engagement made up of a locking protrusion 23 and a locking groove 24 that is locked to the first locking function portion a at the outer peripheral surface thereof, that is, the lower end portion of the outer peripheral surface of the main body portion 18. In addition to forming the stop function portion b, a short cylindrical inner cylinder piece 26 is provided in a suspended manner via the inner hook-shaped bottom rod piece 25, and a plurality of the inner cylinder piece 26 and the inner cylinder piece 26 are provided on the entire surface. (In the case of the illustrated embodiment, two split grooves 28 are provided).
[0033]
The outer peripheral surface of the inner cylinder piece 26 constituting the assembled portion 22 is a tapered surface-like inclined surface 27 whose diameter is increased upward, and this inclined surface 27 has a diameter dimension at the lower end and a diameter dimension at the upper end. The height and the inclination angle are set so that the difference is at least twice the locking depth dimension of both the locking function parts a and b.
[0034]
The inner cylindrical body 29 (see FIG. 9), which is a constituent member of the interior body 16, is entirely molded from metal (may be molded from synthetic resin), and provides a mold surface for the cosmetic K. At the same time, the locking cylinder 34 is curved at the lower end of the linear cylindrical storage cylinder 30 that stores the cosmetic K and protrudes outward. A guide cylinder portion 31 in which a guide hole 32 is formed is provided in a suspended manner.
[0035]
The guide hole 32 of the inner cylindrical body 29 has a split groove shape reaching the lower end edge of the guide cylindrical portion 31, thereby enabling insertion and assembly of the tray body 35. In order to prevent the guide hole 32 from slipping out, a stopper protrusion 33 is provided at the lower end of the guide hole 32 to narrow the width of the guide hole 32 and prevent the screw pin 36 of the tray body 35 from slipping out.
[0036]
In addition, since the seal strip 15 of the seal cylinder 12 is in close sliding contact with the outer peripheral surface of the storage portion 30, an appropriate resistance is given to the rotation of the inner cylinder 29 with respect to the screw cylinder 17. Thus, it is possible to give a preferable feeling to the feeding operation of the cosmetic K.
[0037]
A tray body 35 (refer to FIG. 10 and FIG. 11 below), which is a constituent member of the interior body 16, is provided at the lower end of the outer peripheral surface of the linear cylindrical body that is slidably moved up and down into the inner cylinder body 29. A pair of screw pins 36 that project through the guide holes 32 of the body 29 and screw into the screw grooves 19 of the screw cylinder body 17 are provided.
[0038]
The cap 38 (see FIG. 1) having a cylindrical cylindrical shape has an inner peripheral surface of the lower end opening that is the same regular polygonal shape as the outer peripheral surface of the removable cylindrical piece 10 of the outer cylindrical body 2, thereby the outer cylindrical body 2. A seal cylinder piece 39 having a top-cylindrical shape that is tightly fitted to the storage cylinder portion 30 of the inner cylinder 29 is fixed internally.
[0039]
Thus, since the seal cylinder piece 39 is closely fitted to the inner cylinder body 29, when 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 an “accumulation” accident occurs in which the tip of the cosmetic K strikes the cap 38. However, since the cap 38 is assembled to the outer cylinder 2 so as not to idle, there is no possibility that such an accident will occur.
[0040]
FIGS. 12 and 13 are for explaining the separation of the exterior body 1 and the interior body 16, and as shown in FIG. 12, a cylinder having an inner diameter equal to the diameter of the lower end of the inclined surface 27 of the inner cylinder piece 26. When the shaped unassembly jig M 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 and elastically deformed in the reduced diameter direction (in FIG. 12, Since the two-dot chain line is shown), the first locking function part a and the second locking function part b are unlocked.
[0041]
When the assembly jig M is pulled down from this state, the interior body 16 that is externally held by the assembly jig M comes out of the exterior body 1 and is separated as shown in FIG. .
[0042]
At this time, by providing a functional portion to be engaged with the tip of the disassembly jig M at the upper end of the outer peripheral surface of the inner cylinder piece 26, the exterior body 1 and the interior body 16 using the disassembly jig M are provided. Separation can be easily achieved.
[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 assembly jig M and the inner cylinder piece 26 increases, and separation between the exterior body 1 and the interior body 16 is achieved. Can be made easier.
[0044]
Note that the window hole 21 established at the upper end of the screw cylinder body 17 and the opening hole 37 established at the upper part of the tray body 35 are provided inside the interior body 16 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 material is efficiently and appropriately applied to the molten cosmetic material injected into the liquid.
[0045]
The above-described embodiment relates to a feeding container in which lipsticks are stored, but it goes without saying that any item can be selected as a stored item as long as it can be used as a feeding 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 is needless to say that the top filling method can be applied to the present invention.
[0047]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
In the invention according to claim 1, the separation between the exterior body and the interior body is achieved by elastic deformation of a part of the interior body, and the separation of each component of the exterior body and the interior body after the separation is Since there is no functional part that regulates and holds the assembly between each other, it can be achieved easily without difficulty.
[0048]
In addition, since each component member is separated without causing permanent deformation in this way, it can be easily reused, and a high resource saving effect can be obtained.
[0049]
Furthermore, since the upper end of the interior body is opened at the storage cylinder portion of the inner cylinder body, and the lower end thereof is opened at the screw cylinder body, the molding storage of the cosmetics using the interior body as a formwork can be performed on the interior body. It is possible to apply both the top filling method and the bottom filling method of the molten cosmetic.
[0050]
Then , the lower end of the main body of the screw body provided with the second locking function portion is easily bent and elastically deformed in the diameter reducing direction, and the lower end of the screw body is reduced in the diameter reducing direction using the inner cylinder piece. Therefore, it is easy to apply an external force to cause the outer body and the inner body to be separated from each other.
[0051]
In the invention according to claim 2 , since the posture with the mutual assembly of the exterior body and the interior body can be stably and reliably held at an appropriate position, the proper mutual assembly posture of each component member Can be securely held, and thereby a smooth and good operation as a feeding container can be obtained.
[0052]
In the invention according to claim 3 , since the diameter reduction deformation of the inner cylinder piece of the screw cylinder body, that is, the diameter reduction deformation of the lower end portion of the main body portion can be obtained easily and reliably, the exterior body and the interior The body can be easily separated, and the diameter reduction of the inner cylinder piece and the separation of the exterior body and the interior body can be achieved by a series of processes, so that the separation of each component is efficient. Can be achieved well.
[0053]
