Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding container for storing a stick-shaped cosmetic material such as a lipstick so that it can be fed out and fed in.
[0002]
[Prior art]
As one of the delivery containers for storing stick-shaped cosmetics such as lipsticks and stick foundations, the inner cylindrical body and the saucer body, which are constituent parts of the delivery containers, are used as a mold form for stick-shaped cosmetics, Simultaneously with cooling solidification molding of bar-shaped cosmetics by molding by filling and filling from the bottom end opening of the cylinder (bottom filling method) or by filling and filling from the top opening of the inner cylinder (top filling method) There are some that achieve assembly to the feeding container.
[0003]
This product can achieve the formation of the bar-shaped cosmetic and the assembly into the feeding container at the same time, so that it can obtain extremely good productivity. However, the bar-shaped cosmetic is a part located directly in the inner cylinder. And the portion located in the inner cylinder through the saucer body, a difference occurs in the degree of action of the cooling power from the outside to both portions, and the bar-shaped cosmetic machine formed by this difference There was dissatisfaction that the mechanical strength decreased.
[0004]
As a conventional technique of a feeding container that eliminates this dissatisfaction, a through hole that penetrates the wall of the saucer body is formed at the location of the saucer body where cosmetics are joined, and the cosmetic in the saucer body is externally cooled through the through hole. There is one that prevents the rod-shaped cosmetic material from being pulled out or broken from the saucer body by effectively applying force and positioning a part of the rod-shaped cosmetic material in the through hole (for example, see Patent Document 1). .)

Japanese Patent Laid-Open No. 2002-000349
[Problems to be solved by the invention]
However, in the above-described prior art, as is apparent from the explanatory diagram of FIG. 4, the molding of the bar-shaped cosmetic is performed by a combination of the inner cylinder and the saucer body. This combination of the bar-shaped cosmetic, the inner cylinder body and the tray body requires a troublesome handling process in which it must be screwed and assembled to the screw cylinder body. The work had to be done with great care.
[0007]
In addition, when the tray body is simply inserted and assembled into the inner cylinder body, there is no ability to keep the assembly position with respect to the inner cylinder body constant. For this reason, the position of the tray body in the inner cylinder body is a fixed position ( It is necessary to provide a dedicated means for stably holding the inner cylinder body at the lower limit position).
[0008]
Therefore, the present invention was devised to solve the problems in the prior art described above, and the rod-shaped cosmetic is stored and held at the same time as molding, with the inner cylinder body and the tray body being part of the molding surface. For the combination of the inner cylinder that can perform the feeding function, the tray body, and the screw cylinder, the bar-shaped cosmetic is stored at the same time as the molding while maintaining the proper cooling power. Therefore, while maintaining stable and good cooling and solidification molding of the bar-shaped cosmetics, the troublesome handling of the bar-shaped cosmetics after molding is eliminated, and at the time of injection molding of the bar-shaped cosmetics, It aims at holding | maintaining the assembly | attachment position of the saucer body with respect to an inner cylinder body in the position fixed safely.
[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:
Having an exterior body composed of an outer cylinder body having a cap mounting portion at the upper end;
A screw cylinder body that engraves a screw groove on the inner peripheral surface, opens a plurality of window holes in the upper end portion, and is attached to the outer cylinder body 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 cylinder, an insertion assembly is attached so that it can be moved up and down while sliding, and a screw pin that projects through the guide hole of the inner cylinder through the lower end of the outer peripheral surface and engages with the screw groove of the screw cylinder projects. A saucer installed,
Having an interior body consisting of,
It is in.
[0010]
In the invention according to claim 1, in a state where the tray body of the assembled interior body is positioned at the lower limit, the tray body has a plurality of window holes in the lower portion of the upper portion where the cosmetic material enters. The other portion is positioned in the inner cylinder body in such a posture that it is opposed to the upper end portion of the opened screw cylinder body and the other part is protruded from the inside of the screw cylinder body.
[0011]
In addition, since the tray body is in a state where the interior body is configured by combining the screw cylinder body and the inner cylinder body, a relative rotational displacement occurs between the screw cylinder body and the inner cylinder body. Unless this is the case, the position is kept immovable, so that the tray body can be moved to the lower limit position by handling the screw cylinder body and the inner cylinder body so as not to rotate relative to each other with the tray body positioned at the lower limit. Will be held.
[0012]
In this way, with the saucer body positioned at the lower limit, using the bottom filling method or the top filling method, the heated and melted cosmetic is injected and filled into the interior body until it reaches the top of the saucer body, The injected hot-melt cosmetic is cooled and solidified to form a stick-shaped cosmetic, and at the same time, storage and assembly in the interior body is achieved.
[0013]
In the cooling and solidification molding of the cosmetic material, the upper end portion of the screw cylinder body is opposed to the outside of the upper portion and the lower portion of the tray body where the lower end portion of the cosmetic material is filled. Since a plurality of window holes through which cool air can freely pass are formed at the upper end of the screw cylinder, the screw cylinder does not give an insulative effect which is inconvenient for cooling and solidifying molding of cosmetics.
[0014]
For this reason, the heated and melted cosmetic positioned in the upper part of the saucer body is cooled almost evenly without being affected by the screw cylinder, and has a mechanical strength that does not decrease in strength due to uneven cooling. A uniform and stable cosmetic is formed.
[0015]
The invention according to claim 2 is obtained by adding a window hole to the bottom wall portion of the screw groove along the screw groove in the configuration of the invention according to claim 1.
[0016]
In the invention according to claim 2, the window hole can be formed without impairing the helical structure of the screw groove and without causing an undesired decrease in the mechanical strength of the screw body. It becomes easy to increase the opening area of the hole.
[0017]
The invention according to claim 3 is the configuration of the invention according to claim 1 or 2, in the upper part including the place facing the window hole of the screw body in the state where the tray body is located at the lower limit, In addition to the fact that a plurality of open holes are opened.
[0018]
In the invention according to claim 3, since the cooling power acts effectively through the plurality of open holes on the heated and melted cosmetic material located in the upper part of the saucer body, the heat insulation effect of the saucer body is obtained. The heated and melted cosmetic material in the saucer body is efficiently and substantially uniformly cooled without adversely affecting the heated and melted cosmetic material.
[0019]
In addition, a part of the cosmetic located in the upper part of the saucer body is cooled and solidified while being located in the open hole of the saucer body, but this part is an operation for pulling out the molded bar-shaped cosmetic material from the saucer body. On the other hand, it exerts a strong resistance and acts extremely effectively to maintain the assembly of the cosmetic to the saucer.
[0020]
According to a fourth aspect of the present invention, in the configuration of the first, second, or third aspect, when the tray body is positioned at the lower limit, the stopper piece that the threaded pin of the tray body gets over and locks is screwed. This is in addition to being provided in the screw groove portion of the cylindrical body.
[0021]
In this invention of Claim 4, a saucer body is attached with respect to the combination of a screw cylinder body and an inner cylinder body by the latching action of the stop piece of a screw cylinder body with respect to the screwing pin of a saucer body. This state is stably maintained even when the cosmetic is placed at the lower limit position and is handled before the injection molding process of the cosmetic.
[0022]

By providing the pressing protrusion 11, the cap 38 is fitted with an external fitting assembly so that it cannot be displaced.
[0025]
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.
[0026]
A screw cylinder 17 (refer to FIGS. 6 to 8) constituting the inner body 16 is provided with a stopper 19 a having a low projecting height on the inner peripheral surface of the linear cylindrical body 18 and on the groove wall surface at the lower end. The projecting two threaded grooves 19 are engraved, and a plurality of vertical protrusions 20 are provided on the outer peripheral surface of the main body portion 18 to be engaged with the engagement vertical stripes 4 of the outer cylindrical body 2. The part is configured as an assembled part 22.
[0027]
In the upper end portion of the main body portion 18, a plurality of window holes 21 having a slightly smaller width than the screw groove 19 are formed along the screw groove 19 on the bottom wall of the screw groove 19. Is formed in the bottom wall of the screw groove 19 along the screw groove 19, thereby sufficiently reducing the decrease in mechanical strength of the screw cylinder body 17 due to the opening of the window hole 21. Is smaller than the screw groove 19 so that the helix function of the screw groove 19 is not hindered.
[0028]
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).
[0029]
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 height dimension of both the locking function portions a and b.
[0030]
The inner cylinder 29 (see FIG. 9), which is a constituent member of the interior body 16, is entirely molded of metal (may be molded of synthetic resin), and provides a mold surface for the cosmetic K. A guide hole over the entire height range of the lower end of the linear cylindrical storage cylinder 30 that stores the cosmetic K is provided through a locking projection 34 that is curved and configured to protrude outward. The guide cylinder part 31 in which 32 is formed is arranged in a suspended manner.
[0031]
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.
[0032]
Further, since the seal peripheral strip 15 of the seal cylinder 12 is in close sliding contact with the outer peripheral surface of the storage cylinder portion 30, an appropriate resistance is given to the rotation operation of the inner cylinder 29 with respect to the screw cylinder 17. As a result, a favorable feeling of use can be given to the feeding operation of the cosmetic K.
[0033]
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 so as to protrude from the tray body 35. When it is positioned at the lower limit of 16, it climbs over and engages with the stop piece 19 a of the screw body 17.
[0034]
The tray body 35 has a height that allows the upper end portion to protrude upward from the inside of the screw cylinder body 17 in a state where the tray body 35 is located at the lower limit, and is a portion facing the window hole 21 of the screw cylinder body 17. A plurality of open holes 37 are opened in the upper part including the lower part.
[0035]
The open hole 37 is divided into a lower group facing the window hole 21 and an upper group projecting outside the screw cylinder body 17 (see FIG. 10), with the tray body 35 positioned at the lower limit. ing.
[0036]
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.
[0037]
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 fear of such an accident.
[0038]
FIG. 12 is for explaining the cooling and solidification molding by the bottom filling method of the cosmetic material K using the interior body 16. The tray body 35 is positioned at the lower limit, and the storage cylinder portion 30 of the inner cylinder body 29 is shown. The interior body 16 tightly closed by fitting the mold lid 40 on the upper end is held in an inverted position, and the heated and melted cosmetic K is applied from the lower end opened by the inner cylinder piece 26 of the screw cylinder body 17. A fixed amount is poured into the interior body 16 until the liquid level of the heat-melting cosmetic material K reaches the lower end (upper end in FIG. 12) of the upper portion of the saucer body 35 having the open holes 37.
[0039]
When the fixed injection of the heat-melted cosmetic material K into the interior body 16 is completed, the entire interior body 16 is cooled to solidify the cosmetic material K. At this time, as apparent from FIG. Of the open holes 37 formed in the upper part of the saucer body 35 that faces the body 17, those that are located in the lower (upper in FIG. 12) face the window hole 21 of the screw body 17. Therefore, the cooling power is transmitted to the heated and melted cosmetic K through the window hole 21 without being obstructed by the screw body 17.
[0040]
When the molding and storage of the cosmetic material K are completed, as shown in FIG. 13, the interior body 16 with the mold lid 40 removed is inserted into the exterior body 1 from below, and the first locking function part a and the second engagement part are inserted. The stop function part b is locked to achieve assembly of the feeding container.
[0041]
FIG. 14 is a diagram for explaining the separation between the exterior body 1 and the interior body 16, and is a cylindrical disassembly jig M having an inner diameter equal to the diameter of the lower end of the slope 27 of the inner cylinder piece 26. Is pushed up and forcedly fitted to the inner cylinder piece 26, the assembled portion 22 formed with the split groove 28 is bent and elastically deformed (illustrated with a two-dot chain line in FIG. 14). The locking of the first locking function part a and the second locking function part b is released.
[0042]
If the interior body 16 is pulled down with respect to the exterior body 1 in this state, the interior body 16 is pulled out from the interior of the exterior body 1, and separation of the exterior body 1 and the interior body 16 is achieved.
[0043]
In addition, although the above-mentioned Example demonstrated the shaping | molding accommodation of the cosmetics K by a bottom filling system, by means, such as providing a partition in the lower end of the upper end part of the saucer body 35, at the lower end of the upper end part of the saucer body 35, Needless to say, it is possible to carry out the molding and storing of the cosmetic K by the top filling method by providing the bottom function part of the space for storing the hot-melt cosmetic to be poured and filled.
[0044]
【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, since the cosmetic is directly molded and assembled in the interior body that can exhibit the cosmetic delivery function by itself, the handling of the cosmetic after molding can be performed with the exterior body. Only the assembly with the interior body can be carried out, whereby the safety of handling the cosmetic after molding can be enhanced.
[0045]
In addition, since the screw cylinder body does not give an unfavorable heat insulating action to the cooling and solidification molding of the cosmetic material, the heated and melted cosmetic material positioned in the upper end portion of the saucer body is almost unaffected by the screw cylinder body. It will be cooled uniformly, and it will be molded with a uniform and stable mechanical strength without a drop in strength due to uneven cooling.
[0046]
Furthermore, since the interior body constitutes the feeding function portion, the tray body is not displaced up and down unless the screw cylinder body and the inner cylinder body rotate relative to each other, thereby holding the tray body in the lower limit position. It is easy to handle, and accordingly, it is easy to handle at the time of cosmetic molding and maintains a good state.
[0047]
In the invention described in claim 2, the window hole can be provided in a state where the effect can be exhibited safely and sufficiently.
[0048]
In invention of Claim 3, a cooling power can be made to act effectively through a some open hole with respect to the hot-melt cosmetics located in the upper part of a saucer body, and the hot-melt cosmetics in a saucer body Can be cooled efficiently and substantially uniformly.
[0049]
In addition, since the stick-shaped cosmetic part located in the open hole of the saucer body exhibits a strong resistance to the action of the molded stick-shaped cosmetic material coming out of the saucer body, It works very effectively to keep the sticking.
[0050]
In the invention according to claim 4, since the catch piece can be stably held at the lower limit position with respect to the combination of the screw cylinder body and the inner cylinder body by the action of the stopper piece, The interior body can be stably maintained in an appropriate state at the time of handling before the injection molding treatment of the material, whereby a stable and excellent molding of the cosmetic can be obtained.
