Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding container that feeds and uses stick-shaped cosmetics such as lipsticks stored inside an inner cylinder by a relative rotation operation between the outer cylinder and the inner cylinder.
[0002]
[Prior art]
This type of feeding container has a linear cylindrical inner cylinder with a vertically long guide hole extending from the upper end of a short cylindrical base cylinder portion, and is rotatable about the inner cylinder. And an outer cylinder body that is externally fitted so that it cannot be pulled out, and an inner peripheral surface is engraved with a thread groove, and a threading pin that penetrates a longitudinal guide hole through the outer peripheral surface of the cylindrical piece body and screws the tip into the thread groove And a synthetic resin part constituting a container function part comprising a receiving body that is inserted and assembled in the inner cylinder so as to be movable up and down, and a base cylinder part of the inner cylinder. And a metal part comprising: a cylindrical middle tool that is externally fitted to the lower part of the outer cylindrical body; and a cylindrical hook that is fixedly fitted to the middle tool by exposing the upper part of the middle tool. And a cap with a top cylindrical shape that is fitted on the outer cylinder and is detachably fitted to the inner tool.
[0003]
For example, as described in Japanese Utility Model Laid-Open Nos. 64-14321 and 61-18817, stick-shaped cosmetics such as lipsticks are made of a cylindrical inner cylinder that is a cylindrical body. After assembling inside the body so that it can be moved up and down, the inner cylinder is assembled to the cylindrical middle tool and the hook, and then the molten cosmetic is injected and filled from the bottom of the middle tool and the hook, and the whole is cooled and solidified evenly. After that, a stick-shaped cosmetic product such as a lipstick is formed by sticking a sealing member such as a seal to the opening of the inner tool and the hakama.
[0004]
Conventionally, a feeding container used for a bar-shaped cosmetic or the like is made of a synthetic resin after a synthetic resin part made up of an inner cylinder, an outer cylinder, etc. and a metal part made up of an inner tool and a hook are assembled. The part and the metal part are fixed with an adhesive, or the members are structurally fixed to form a feeding container. When the container is used, each member cannot be easily separated.
[0005]
[Problems to be solved by the invention]
In recent years, taking into account the global environment and the like, it is obliged to separate and collect waste materials. In addition, there is increasing interest in recycling in order to limit the amount of waste and effectively use resources.
[0006]
However, in the case of a conventional stick-shaped cosmetic delivery container, the synthetic resin part and the metal part are fixed so that they cannot be separated, so different materials such as the synthetic resin part and the metal part are separated and discarded. There was a problem that became difficult. In addition, recyclable members such as metal parts need to be recycled and utilized as much as possible in order to effectively use resources and to reduce product costs.
[0007]
Therefore, the present invention was devised to solve the problems in the prior art, and a metal part composed of an inner tool and a hook and the like, and a synthetic resin part composed of an inner cylindrical body, etc. It is a technical problem to enable easy separation without obstructing the use of the metal, and thus it is possible to recycle members such as metal parts.
[0008]
[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 linear cylindrical shape in which a vertically long guide hole is opened over substantially the entire height range from the upper end of the short cylindrical base cylindrical portion. The inner cylinder is erected , and is fitted to the inner cylinder so as to be rotatable and non-removable, and an inner cylinder is formed on the outer peripheral surface of the cylindrical piece. A container comprising: a receiving body that is inserted through the vertically long guide hole of the body and screwed into the inner cylindrical body so as to be moved up and down by protruding a screwing pin that is screwed into the thread of the outer cylindrical body A cylindrical plastic tool that has a synthetic resin portion that constitutes a functional part of the inner cylindrical body, and is externally fitted to the base cylindrical part of the inner cylindrical body so as to be idled to the lower portion of the outer cylindrical body. In addition, it has a metal part composed of a cylindrical hakama that is fixedly exposed by exposing the upper part of the inner tool, and is fitted on the outer cylinder and is detachably fitted to the inner tool. It has a top cylindrical cap, the inner tool has a protruding part on the inner peripheral surface, and the base cylinder part of the inner cylinder is inclined so that the protruding part of the inner tool is loosely fitted on the outer peripheral surface. The turning torque for releasing the assembly of the convex part of the inner tool and the concave groove of the base cylindrical part of the inner cylinder is larger than the rotational torque for moving the tray body up and down. It is set and set to be smaller than the rotational torque that idles the tray body and the outer cylinder body.
[0009]
The turning torque for releasing the assembly of the convex part of the inner tool and the concave groove of the base cylindrical part of the inner cylinder is set to be larger than the turning torque for moving the saucer up and down. Sometimes, even if the user moves the tray body up and down, the coupling between the convex part of the middle tool and the concave groove of the base cylindrical part of the inner cylindrical body is not released. The base cylinder part does not come off, and the feeding container can be used in a state where the inner tool is fixedly fitted to the base cylinder part.
[0010]
On the other hand, the rotational torque for releasing the assembly of the convex portion of the inner tool and the concave groove of the base cylindrical portion of the inner cylinder is set to be smaller than the rotational torque that causes the tray body and the outer cylinder to idle. Therefore, if the user rotates the feeding container with an unreasonable force that causes the saucer body and the outer cylinder to idle, before the saucer body and the outer cylinder idle, The loose coupling with the concave groove of the base cylinder part of the body is released, the inner fitting fitted on the base cylinder part is removed, and the metal part and the synthetic resin part are separated.
[0011]
For this reason, the metal part and synthetic resin part which comprise a feeding container can be separated and collected easily, and a metal part can be recycled and used effectively.
[0012]
The invention according to claim 2 is obtained by adding, to the configuration of the invention according to claim 1, the concave groove of the inner cylindrical body of the base cylinder portion being inclined in the direction opposite to the screw groove of the outer cylindrical body. It is.
[0013]
In the invention according to claim 2, the concave groove provided on the outer peripheral surface of the base cylinder portion of the inner cylinder body is inclined in the direction opposite to the screw groove of the outer cylinder body. When the feeding container is rotated in the direction opposite to the rotating direction to be displaced, the convex portion of the inner tool and the concave groove of the base cylindrical portion of the inner cylindrical body are loosely engaged.
[0014]
Usually, the user can know that the saucer body has been moved up and down to the upper limit by the protruding amount of lipstick or the like filled in the saucer body when the feeding container is used.
[0015]
For this reason, the user sees the amount of protrusion such as lipstick protruding from the feeding container, recognizes that the saucer body has been moved up and down to the ascending limit, and cannot overdo the rotation torque that causes the saucer body to be displaced up and down. Without forcibly rotating the feeding container with force, the feeding container is rotated in the opposite direction to store lipstick or the like in the feeding container.
[0016]
Therefore, when using the feeding container, the user recognizes the rising limit of the tray body, and moves the tray body up and down without rotating the feeding container with an unreasonable rotational torque greater than the rotational torque that moves the tray body up and down. When the feeding container is rotated in the direction opposite to the rotating direction to be displaced to lower the tray body, the rotational torque for moving the tray body up and down is set larger, and the tray body and the outer cylinder are idled. The convex part of the inner tool and the base of the inner cylindrical body by the rotational torque for releasing the assembly of the convex part of the middle tool set to be smaller than the rotational torque and the concave groove of the base cylindrical part of the inner cylindrical body Since the assembly of the cylindrical portion with the concave groove is not released and the state in which the inner fitting is fixedly fitted to the base cylindrical portion is maintained, the fear that the feeding container will be unintentionally separated is eliminated.

[0020]
As shown in the partially enlarged view of FIG. 1, the base cylinder portion 2 is provided with an inclined concave groove 2 a that loosely engages with a convex portion 7 a of a middle tool 7 described later on the outer peripheral surface thereof.
[0021]
Further, as shown in FIG. 3, a linear cylindrical inner cylindrical body 3 having a vertically long guide hole is provided upright from the upper end of the short cylindrical base cylinder portion over substantially the entire height range .
[0022]
Similarly , a linear cylindrical outer cylinder 4 is externally fitted to the inner cylinder 3, and the base cylinder portion 2, the inner cylinder 3 and the outer cylinder 4 are integrally assembled. A screw groove 4 a is formed on the inner peripheral surface of the outer cylinder 4. Inside the inner cylindrical body 3, a tray body 5 consisting of a cylindrical piece 5a and a projecting threading pin 5b is inserted and assembled, and the threading pin 5b penetrates the vertically long guide hole 3b and enters the thread groove 4a. Screw together.
[0023]
These inner cylinder 3, outer cylinder 4, saucer body 5, and the like provided at the upper end of the base cylinder part 2 have a function of taking in and out the lipstick filled in the saucer body 5 from the container 1, Each member constitutes a synthetic resin part formed of synthetic resin.
[0024]
Further, the inner tool 7 to which the hook 8 is fitted is provided with a convex portion 7a projecting from the inner peripheral surface thereof. The middle tool 7 is externally fitted to the base cylinder part 2, and the convex part 7a and the ditch | groove 2a play loosely. The middle tool 7 and the hook 8 constitute a metal part formed using a predetermined metal.
[0025]
Next, the function of the feeding container 1 of this example will be described based on FIGS. 4 and 5. FIG. 4 shows a synthetic resin part in which an outer cylindrical body 4 is externally fitted to an inner cylindrical body 3 provided at the upper end of the base cylindrical part 2, and a tray body 5 is inserted and assembled in the inner cylindrical body 3. FIG. 5 is a perspective view including a partial cross-sectional view showing a metal part in which a hook 8 is externally fitted to the tool 7.
[0026]
FIG. 5 is a perspective view including a partial cross-sectional view showing a state in which the inner cylinder 3 and the outer cylinder 4 provided at the upper end of the base cylinder portion 2 are fitted in the middle tool 2. In this example, the outer cylinder 4 is formed of a transparent synthetic resin member.
[0027]
As shown in FIG. 5, when the middle tool 7 is fitted on the base tube portion 2 and the middle tool 7 is turned by a predetermined turning torque, the convex portion 7a and the concave groove 2a are loosely engaged with each other. The middle tool 7 is fixedly fitted to the cylindrical portion 2.
[0028]
The saucer body 5 moves the vertically long guide hole 3b up and down along the screw groove 4a as the container 1 rotates.
[0029]
Further, the vertically long guide hole 3b is provided with a top dead center hole 3c as an ascending limit and a bottom dead center hole 3d as a descending limit, in which the tray body 5 does not move up and down any further. The top dead center hole 3c and the bottom dead center hole 3d are opened in a state protruding in the circumferential direction from the vertically long guide hole 3b. When the screw pin 5b of the tray 5 is fitted into the top dead center hole 3c or the bottom dead center hole 3d, the screw pin 5b is detached from the top dead center hole 3c or the bottom dead center hole 3d even if the container 1 is rotated. Therefore, when the container 1 is rotated with an unreasonable rotational torque that is greater than or equal to the rotational torque that causes the tray body 5 to be moved up and down without the tray body 5 being displaced up and down, the screw pin 5b is connected to the top dead center hole 3c or With the end fitted in the bottom dead center hole 3d, the tip of the screw pin 5b rides on the screw groove 4a, and the tray body 5 and the outer cylinder body 4 are idled.
[0030]
The rotational torque for releasing the assembly of the convex portion 7a and the concave groove 2a is set to be larger than the rotational torque for moving the tray body 5 up and down, and the rotational torque causing the tray body 5 and the outer cylinder body 4 to idle. Is set smaller than.
[0031]
When the rotational torque for releasing the assembly of the convex portion 7a and the concave groove 2a is set to be larger than the rotational torque for moving the saucer body 5 up and down, when the user uses the container 1, the saucer Even if the container 1 is rotated with a rotational torque that moves the body 5 up and down, the assembly of the convex portion 7a and the concave groove 2a is not released, and the inner tool 7 is stably fitted onto the base cylindrical portion 2. The container 1 can be used in a state.
[0032]
On the other hand, when the rotational torque for releasing the assembly of the convex portion 7a and the concave groove 2a is set to be smaller than the rotational torque for idling the tray body 5 and the outer cylinder body 4, the user receives the tray body. When the container 1 is rotated with an unreasonable rotational torque that is greater than or equal to the rotational torque that causes the 5 to be moved up and down, the convex portion 7a and the concave groove 2a are assembled before the tray body 5 and the outer cylinder body 4 idle. Is released, the inner tool 7 is detached from the base cylinder part 2, and the metal part and the synthetic resin part can be easily separated.
[0033]
Generally, the rotational torque for moving the tray body 5 up and down is set to 300 g or less, and the rotational torque for idling the tray body 5 and the outer cylinder body 4 is set to 2.0 kg. It is appropriate to set the rotation torque for releasing the assembly with the concave groove 2a to 1.0 to 1.5 kg.
[0034]
In this way, in the normal use, the feeding container 1 is in a state where the assembly of the convex portion 7a and the concave groove 2a is not released, and the inner tool 7 is fixedly fitted on the base cylinder portion 2, and the user can The container 1 can be used with confidence. On the other hand, when the user rotates the container 1 with an unreasonable rotational torque that is greater than that during normal use, the assembly of the convex portion 7a and the concave groove 2a is released, and the inner tool 7 can be easily removed from the base cylinder portion 2. The synthetic resin part and the metal part can be easily separated, separated and discarded, or recycled according to the material, and the recovery of the recycled resources can be easily achieved.
[0035]
As shown in FIG. 4, in the illustrated embodiment, the concave groove 2a provided on the outer peripheral surface of the base cylinder portion 2 is engraved so as to incline in the direction opposite to the screw groove 4a. When the container 1 is rotated in the direction opposite to the direction of moving up and down, the convex portion 7a and the concave groove 2a are loosely engaged.
[0036]
Normally, when the user uses the feeding container 1, the receiving body 5 is moved up and down to the top dead center hole 3 c at the upper limit by the protruding amount of the lipstick or the like filled in the receiving body 5. It can be known that the screwing pin 5b is inserted into the top dead center hole 3c.
[0037]
When the user sees the protruding amount of the lipstick or the like protruding from the container 1 and recognizes that the saucer body 5 is displaced up and down to the ascending limit, an unreasonable force greater than the rotational torque that causes the saucer body 5 to be displaced up and down. Without forcibly rotating the container 1, the container 1 is rotated in the opposite direction to store lipstick or the like in the container 1.
[0038]
Further, the rotational torque for releasing the assembly of the convex portion 7 a and the concave groove 2 a of the container 1 is set to be larger than the rotational torque for moving the tray body 5 up and down, and the tray body 5 and the outer cylinder body 4. Therefore, the user recognizes that the tray body 5 has been moved up and down to the ascending limit, and is more than the rotational torque that moves the tray body 5 up and down. When the container 1 is rotated in the opposite direction without rotating the container 1 by force, the assembly of the convex portion 7a and the concave groove 2a is not released, and the convex portion 7a and the concave groove 2a are formed. Since the state where the inner tool 7 is fixedly fitted to the base cylinder portion 2 is maintained, the containers 1 are not separated unintentionally.
[0039]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained. In the first aspect of the present invention, a linear cylindrical inner cylindrical body having a vertically long guide hole is provided upright from the upper end of the short cylindrical base cylinder portion , An outer cylinder body that is rotatably fitted to the cylinder body so that it cannot be pulled out, and an inner peripheral surface is engraved with a thread groove, and a longitudinal guide hole is passed through the outer peripheral surface of the cylindrical piece body and the tip is threaded into the thread groove. A synthetic resin part constituting a container function part including a receiving body that is inserted and assembled to the inner cylinder so as to be movable up and down, and a base cylinder part of the inner cylinder It is made of a metal that consists of a cylindrical middle fitting that fits externally and fits in the lower part of the outer cylinder so that it can idle, and a cylindrical hook that exposes the upper part of the middle tool and that is fixedly fitted outside. In a feeding container comprising a top portion and a cap with a crest that is fitted on the outer cylinder and is detachably fitted to the inner tool, the inner tool projects a convex portion on the inner peripheral surface. The base cylindrical part of the inner cylinder is provided with an inclined concave groove in which the convex part is loosely fitted on the outer peripheral surface, and the assembly of the convex part of the inner tool and the concave groove of the base cylindrical part of the inner cylindrical body is released. The turning torque is set larger than the turning torque that moves the saucer body up and down, and smaller than the turning torque that idles the saucer body and the outer cylinder body. Even if a user rotates a delivery container, it will be in the state by which the inner tool was fixedly fitted by the base cylinder part, and can use a container in comfort.
[0040]
On the other hand, the rotational torque for releasing the assembly of the convex portion of the inner tool and the concave groove of the base cylindrical portion of the inner cylinder is set to be smaller than the rotational torque that causes the tray body and the outer cylinder to idle. Therefore, if the feeding container is forcibly rotated with a large rotational torque that is greater than the rotational torque that moves the tray body up and down, before the tray body and the outer cylinder are idle, The assembly of the concave groove of the base cylinder part is released, the inner tool is detached from the base cylinder part, and the metal part and the synthetic resin part can be easily separated.
[0041]
In this way, the synthetic resin part and the metal part can be easily separated according to the difference in the turning torque for turning the feeding container, and can be separated and discarded or recycled by material, making it easy to collect recycled resources. To be achieved.
[0042]
In the invention described in claim 2, when the feeding container is rotated in a direction opposite to the direction in which the tray body is moved up and down, the convex portion and the concave groove are loosely engaged.
[0043]
Normally, when using the feeding container, the user recognizes that the tray body has been moved up and down to the upper limit due to the amount of protrusion of the lipstick etc. filled in the tray body, and beyond the turning torque that moves the tray body up and down. Without rotating the feeding container with a strong force, the feeding container is rotated in the opposite direction to store the lipstick or the like in the container.
[0044]
Therefore, when using the feeding container, the user recognizes the ascending limit of the saucer body, and does not rotate the feeding container with an unreasonable turning torque that is greater than the turning torque that moves the receiving body up and down. In order to rotate the feeding container in the opposite direction to lower the tray body, it is set to be larger than the rotational torque that moves the tray body up and down and smaller than the rotational torque that causes the tray body and the outer cylinder to idle. With the turning torque for releasing the set projection of the center tool and the groove of the base cylinder part of the inner cylinder, the groove of the base tool and the base cylinder part of the inner cylinder Since the assembly is not released and the state in which the inner tool is fixedly fitted to the base cylinder portion is maintained, the possibility that the feeding container is unintentionally separated is eliminated.
