DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-shaped decorative material feeding container. In particular, it relates to a feeding mechanism of a stick-shaped cosmetic material feeding container.

[0002]

2. Description of the Related Art As shown in Japanese Patent No. 3029834, a feeding mechanism of a stick-shaped decorative material feeding container is configured such that a front cylinder is rotatably connected to a container body and a lead chuck member having a cosmetic material holding portion at a front end. And a means (rotation stopping mechanism) for synchronously rotating the front cylinder and the cosmetic material holding portion of the core chuck member is provided, and the core chuck member is axially moved by the screwing mechanism of the container body and the core chuck member. To the feeding mechanism.

However, the screwing mechanism comprises a molded male screw and a female screw, and since such a male screw and a female screw usually have a structurally inevitable gap,
It was assumed that the screwing mechanism would rattle.

[0004] In addition, even though the user has reached the upper limit of the rod-shaped cosmetic material in the rod-shaped cosmetic material feeding container, the user tries to further pull out the rod-shaped cosmetic material core and overloads the feeding mechanism by rotation. There was something.

Conversely, when the bar-shaped decorative material located near the lower limit at the time of the lowering is overloaded so as to lower further than the lower limit, it is often the case that the bar-shaped decorative material is in use. In some cases, the load may lead to breakage of the feeding mechanism or the stick-shaped cosmetic material feeding container itself.

For this reason, a threshold value is assumed for an overload exceeding the load applied during normal use in the ascending and descending limits, and when a load exceeding the threshold is applied during use, a feeding mechanism or a rod-like mechanism is used. It was decided that even if the container for dispensing cosmetics was broken, there was no help for it.

In order to improve the feeling of use, a leaf spring or O
In some cases, an elastic body such as a ring is installed in a portion where the front cylinder and the container body rotate, and a sense of quality is imparted by giving weight to the sliding feeling by frictional resistance.

[0008]

According to the present invention, there is provided an elastic cylinder having a through hole having a diameter smaller than the outer diameter of the spiral portion of the core chuck member. The core chuck member is constantly subjected to frictional resistance by the elastic tubular body, thereby creating a weight of sliding, and is capable of withstanding the overload at the limit of extension of the feeding and the lowering of the core. Thus, it is intended to prevent the screwing mechanism from being broken.

[0009]

According to a first aspect of the present invention, there is provided a stick-shaped cosmetic material feeding container accommodating a stick-shaped decorative material, wherein the stick-shaped decorative material feeding container is configured to feed the stick-shaped decorative material through a front opening. A tube, a container main body having means for rotatably connecting to the front tube, a core chuck member including a cosmetic material holding portion for holding the rod-shaped cosmetic material and a spiral portion, and the front tube; A rotation stopper mechanism provided with a means for rotating the lead chuck member in synchronization with the core chuck member, and an elastic cylindrical body provided with a through hole having a diameter smaller than the outer diameter of the spiral portion of the lead chuck member, having elastic friction. Means for winding the elastic cylindrical body and the container body synchronously while being wound around the core chuck member, an engaging portion provided on an inner peripheral surface of the through hole, and the spiral portion are screwed together. And a screwing mechanism.

According to a second aspect of the present invention, in the stick-shaped cosmetic material feeding container accommodating the stick-shaped decorative material, the stick-shaped decorative material feeding container includes a front cylinder for feeding the rod-shaped cosmetic material from a front end opening, and a front cylinder. A container body having means for rotatably connecting the container body, a core chuck member having a cosmetic material holding portion for holding the rod-shaped cosmetic material and a spiral portion, and the container body and the core chuck member being synchronized with each other. A rotation stopping mechanism having a rotating means, and an elastic cylindrical body having a through-hole smaller than the outer diameter of the spiral portion of the core chuck member are wound around the core chuck member with elastic friction. A screwing mechanism for screwing the engaging portion provided on the inner peripheral surface of the through hole and the spiral portion.

In a third aspect of the present invention, the engaging portion provided in the through-hole of the elastic cylinder is screwed with the spiral portion of the core chuck member and is deformable with respect to the spiral portion.

In the fourth invention, the spiral portion of the lead chuck member is a multi-start thread.

In a fifth aspect of the present invention, a plurality of projections are randomly provided on the inner peripheral surface of the through hole of the elastic cylindrical body to serve as the engaging portion.

In a sixth aspect, the elastic cylinder is
When the front cylinder and the container main body are relatively rotated, the front cylinder and the container main body are rotated in synchronization with each other, and a means is provided for imparting resistance to the relative rotation between the front cylinder and the container main body. Was.

[0015]

According to the first and second aspects of the present invention, the through-hole of the elastic cylindrical body is made smaller than the outer diameter of the spiral portion of the core chuck member, so that the core chuck member has elastic friction. The wound elastic cylinder is a rod-shaped cosmetic material feeding container that exerts a weight of sliding by a completely new screwing mechanism that does not feel rattling caused by screwing of a conventional male screw female screw. In an ascending limit and a descending limit, when an overload is applied, an elastic portion is elastically deformed with respect to a core chuck member by an elastically deforming engagement portion provided in a through hole. In addition, the feeding mechanism and the decorative material container are prevented from being broken.

In the stick-shaped decorative material feeding container according to the first aspect of the present invention, the elastic cylindrical body is fixed to the container body by means for synchronously rotating. The container is fed out from the front-end opening of the front cylinder while rotating in synchronization with the front cylinder. In the stick-shaped decorative material feeding container of the second invention, the elastic cylinder is rotated by the means synchronized with the front cylinder. Since it is fixed to the front cylinder side, the stick-shaped decorative material is fed out while rotating relative to the front cylinder by the rotation of the front cylinder and the container body.

In any case, even in the case of a rod-shaped cosmetic material dispensing container having a high dispensing speed, the core chuck member does not drop down at any position due to dispensing sliding by the through hole of the elastic cylindrical body, and is transported. Since the feeding device does not work due to vibration or vibration, a stick-shaped cosmetic material feeding container that does not require a lock mechanism for the feeding device can be provided.

In the fourth invention, the spiral portion is connected to the lead 1.
By using a multi-threaded screw whose distance (moving distance per rotation) is twice or more the pitch P (distance between screw and thread), when the elastic cylinder and the helical portion are screwed together, the fifth Even if a plurality of projections are randomly provided in the through-hole of the elastic cylindrical body and used as an engagement portion as in the invention, the multi-threaded screw picks up the screwing surface of the projection and crushes the unnecessary projection. To establish a screwing mechanism.

In the sixth aspect, when the front cylinder and the container main body rotate relative to each other, the elastic cylindrical body rotates synchronously with one of the first cylinder and the container main body, and the relative cylindrical movement between the front cylinder and the container main body. Since a means for imparting resistance to rotation is provided, there is no need for an O-ring or the like which is a means for imparting resistance when the conventional front cylinder and the container body are relatively rotated. Since the rotation is related to the rotation of the front cylinder, the container body, and the core chuck member, there is an excellent effect that rattling between these members can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 to 7 are views showing a stick-shaped decorative material feeding container 1 according to a first embodiment of the present invention.
1 shows a vertical partial sectional view of the stick-shaped decorative material feeding container 1 of the present invention, FIG. 2 shows an AA sectional view in FIG. 1, and FIG. 3 shows a BB sectional view in FIG. FIG. 4 shows a state in which the stick-shaped decorative material feeding container 1 of the present invention has been pushed up to the ascending limit, and FIG. 5 shows each member used in the present embodiment and the number of a characteristic portion of each member for each member. ing.

FIG. 6 is a sectional view taken along the line CC of the lead chuck member 30 used in the present invention, and FIGS.
It is a figure for explaining other examples of a screwing mechanism in detail.

FIG. 1 shows a stick-shaped decorative material feeding container 1 of this embodiment.
As shown in the figure, the front cylinder 10 (first cylinder) and the outer cylinder 4 each having a tip opening hole 11 at the tip where the rod-shaped decorative material A advances and retreats.
The core chuck member 30 is rotatably connected to the container main body 3 having the first cylindrical member 0 (second cylindrical body), and has a cosmetic material holding portion 31 in which the tail of the rod-shaped cosmetic material A is supported by the claw pieces 39.
And the stopper member 70 and the elastic cylinder 60 are housed therein.

The core chuck member 30 has a spiral portion 34 having a convex vertex 33 as shown in FIG.
The lead is formed as a multi-start thread equal to an integral multiple of the pitch, and has a spline-shaped cross section. The lower end is provided with a concave annular portion 37 into which the inner projection 71 of the stopper member 70 fits.

In the first embodiment, a multi-threaded screw in which the lead 1 (the distance traveled during one rotation) is equal to eight times the pitch p is employed in the spiral portion 34 screwed to the elastic cylinder 60. .

Next, a through hole 61 is provided in the elastic cylinder 60 which rotates in synchronization with the outer cylinder 40. The inner diameter of the engaging portion of the through hole 61 is the outer diameter of the rod body 32 of the core chuck member 30. It is manufactured with L2 having a smaller diameter than L1.

An engaging portion 39b which is slightly wider than the claw portion 39 is provided below the claw portion 39.
Numeral 9b is engaged with the sliding groove 12 of the front cylinder 10 shown in FIG.

Further, the engaging portion on the inner periphery of the through hole 61 of the elastic cylinder 60 mounted inside the outer cylinder 40 so as to rotate in synchronization with the outer cylinder 40, and the spiral portion 34 of the core chuck member 30. Constitute a screwing mechanism.

The elastic cylinder 60 is provided within the front cylinder 10 within the front cylinder 1.
Since the outer cylinder L has a front cylinder fitting portion 65 that rotates with the outer cylinder 0, the outer diameter L3 is brought into contact with the interior of the front cylinder 10 so that the outer cylinder L3 can be appropriately rotated when the front cylinder 10 and the container body 3 relatively rotate. It is possible to apply resistance with a great rotational friction.

When the front cylinder 10 and the outer cylinder 40 are relatively rotated, the lead chuck member 30 supporting the rod-shaped decorative material A is advanced and retracted by a feeding mechanism including a rotation stopping mechanism and a screwing mechanism.

In this embodiment, a multi-threaded screw having a lead 1 equal to eight times the pitch p is employed for the spiral portion 34 screwed to the elastic cylinder 60. One of the reasons is that a multi-threaded screw is used. The point that the screwing mechanism by the screw is excellent in strength in relation to the elastic cylinder is raised.

Regarding the strength of the screwing mechanism, the elastic cylinder 6
A description will be given with reference to FIG. The dashed-dotted line 33a indicates the peak of the convex portion of the single helix, and the sum of the dashed-dotted line 33a and the two-dot dashed line 33b is 8
The convex vertex of the spiral is shown.

Conventionally, the strength of the screwing mechanism in the decorative material container is made of a material such as plastic, which can ignore the elasticity. Therefore, a screwing mechanism using a single thread is sufficient.

However, in the case of this embodiment, since the threaded surface of the female screw is easily deformed due to elasticity, the single projection screw 67 is screwed into one projection 67a when a load is applied during makeup. Since the load is concentrated on the mating surface, the threaded surface may not be able to withstand or deform due to the elasticity of the projection 67a, and the core chuck member may fall down due to the load in the container body during makeup. It is preferable from the viewpoint of the stability of the feeding mechanism that the load is dispersed by increasing the surface area.

Therefore, in the present embodiment, a multi-start screw is employed as an advantageous means for distributing a load while having the same lead as the single-start screw. In other words, even if the threads have the same height, even if the leads are the same, for example, an eight-threaded screw can obtain eight times the threaded surface as compared with a threaded surface obtained with a single thread, which is advantageous in strength. That's it.

Next, the operation of the stick-shaped decorative material feeding container 1 shown in FIG. 1 will be described. First, when the front cylinder 10 is rotated with respect to the outer cylinder 40 which is the container body 3, the sliding groove 12 of the front cylinder 10 is rotated.
The leading cylinder 10 and the core chuck member 30 are rotated by a rotation stopping mechanism including an engagement portion 39b of the core chuck member 30 that
And rotate synchronously.

On the other hand, the elastic cylinder 60 is mounted on the step 45b provided inside the outer cylinder 40, and the spline engagement portion 45 and the vertical rib 64 provided on the outer periphery of the elastic cylinder 60 are provided. The elastic cylinder 60 rotates synchronously with the outer cylinder 40.

Then, the rod body 32 of the core chuck member 30
Penetrates through the through hole 61 of the elastic cylindrical body 60 and
Since the screw portion 34 and the engaging portion 68 on the inner peripheral surface of the through hole 61 form a screwing mechanism, the core chuck member 30 functions as a feeding mechanism while rotating with respect to the elastic cylinder 60. At the same time as moving in the axial direction,
The rod-shaped decorative material A whose tail is supported at the front end starts to protrude from the front end opening hole 11 while rotating synchronously with the front cylinder.

The screwing mechanism of the present embodiment is shown in FIG.
As shown in the figure, the inner periphery of the through-hole 61 of the cylindrical elastic cylinder 60 having no projections or the like having irregular inner peripheral surfaces (such as frosted glass or fingerprints) which cannot be measured as normal dimensions on the inner peripheral surface. The spiral portion 34 of the core chuck member 30 is screwed into the engaging portion 68 on the surface. At this time, the relationship between the spiral portion 34 and the through hole 61 is such that the through hole 61 has a smaller diameter than the spiral portion 34. Therefore, at the time of attachment, when the spiral portion 34 is screwed into the through hole 61 in the same manner as when a wood screw is screwed in, the top of the convex portion of the spiral portion 34 is provided on the inner peripheral surface of the through hole 61 in the through hole 61. A threaded surface is formed by pressing the engaging portion 68 and threading a female screw (not shown). The formed screwing surface and the flank of the male screw of the screw portion are screwed together to establish a screwing mechanism.

At this time, when an internal thread is screwed into the engaging portion 68 of the through hole 61, a strain is generated. A part of the strain may exceed the elastic limit and become a permanent strain. It is desirable to use a material that has physical properties that slowly dissolves over time.

In this embodiment, when the internal thread is threaded into the through hole, the rod 32 of the core chuck member 30 always slides through the through hole 61 of the elastic cylinder 60 with friction. As a result, there is no backlash and frictional resistance is generated during feeding.

The material of the elastic cylinder used in the present invention is N
Rubbery elastic bodies such as R, NBR, silicone rubber, EPT,
Alternatively, an elastomer, a sponge-like material, or the like is suitable.

FIG. 4 is a view showing a state in which the lead chuck member 30 is pulled up to the ascending limit. The stopper member 70 connected to the rear end of the lead chuck member 30 has an upper end surface 70a.
Is the ascending limit contacting the lower end surface 63 of the elastic cylindrical body 60,
At this time, when the screwing mechanism is rotated to further raise and the screwing mechanism is overloaded, the screwing surface of the engaging portion 68 is deformed, and the elastic cylindrical body 60 and the core chuck member 30 idle and rotate. The stick-shaped cosmetic material feeding container 1 is prevented from being broken.

When the container main body 3 is rotated with respect to the front cylinder 10 in the opposite direction to that at the time of feeding, the stick-shaped decorative material A is retracted in the front cylinder 10 by the feeding mechanism, and the engaging portion of the core chuck member 30 is engaged. The rear end of 39b abuts on the upper end surface of the elastic cylindrical body 60, and the lower limit is reached as shown in FIG.

As shown in FIGS. 8A and 8B, the projection 6 is formed on the inner peripheral surface of the through-hole 61 of the elastic cylinder 60.
7, an engaging portion 68 including a plurality of projections 67 is provided, and this is screwed to the spiral portion 34 of the core chuck member 30 to form a screwing mechanism.

Further, as shown in FIGS. 9A and 9B, the engaging portions 68 on the inner peripheral surface of the through-hole 61 of the elastic cylindrical body 60 are arranged at random regardless of the pitch and the lead of the male screw. The projections 67, 67a, and 67b may be the projections 67 that form the spiral portion 34 of the core chuck member 30. Of the projections 67 that are randomly arranged, 67a is screwed into the screwing surface. When formed, the screwing mechanism is established.

The shape of the engaging portion 68 formed on the inner peripheral surface of the through hole 61 of the elastic cylindrical body 60 is not limited to a substantially hemispherical projection, but may be a ridge, a triangular pyramid, a cone, or the like. It may be shaped.

In such an engaging portion, the threaded surface can be made to appear continuously during idling, so that the click feeling when the male screw gets over the female screw can be extremely reduced, and a part thereof can be reduced. Even if one of the protrusions becomes worn, the screwing mechanism is established by the other protrusions, so that it is possible to provide a stick-shaped cosmetic material feeding container having excellent durability and a completely new feeling of use.

The first advantage of the feeding mechanism of the present embodiment is that the screwing mechanism of the present embodiment does not need to form a normal female screw, and further, does not need to align the male screw and the female screw, and the rod body 32 Only by making the diameter of the through-hole 61 smaller than the diameter of the spiral portion of the above, a highly accurate relationship between the male screw and the female screw can be obtained, and the through-hole 61 of the elastic cylindrical body 60 is Since it is possible to constantly apply frictional resistance to the screw 32, mechanical rattling at the time of rotation which is inevitably generated by screwing a normal female screw and a male screw is eliminated, and a moist sliding feeling can be produced. It is.

The elastic friction given to the core chuck member by the elastic cylindrical through-hole is smaller than the outer diameter of the helical portion, so that the through-hole gives the elastic friction and the elastic friction in the through-hole. May be provided with a screw that engages with the helical portion, and the inner diameter of the screw may be brought into contact with the helical portion to generate elastic friction.

Further, conventionally, in the case where destruction or disassembly of the container body is unavoidable due to structural overload, a threshold value for destruction is set, and if a force greater than the numerical value is applied, the container is destroyed. It was an unavoidable phenomenon.

However, according to the second advantage of the present invention,
The rod body 32 of the core chuck member 30 idles in the through-hole 61 of the elastic cylindrical body 60 against an overload that causes the core chuck member 30 to rotate further at the extension limit and extension limit. Thus, it is possible to prevent destruction due to overload and disassembly of the container body, which were inevitable in conventional containers.

Third, the elastic cylinder 6 in this embodiment is
In the case of 0, since the frictional resistance is given when the front cylinder 10 and the outer cylinder 40 relatively rotate, the rod-shaped decorative material A is unprepared from the front opening 11 of the front cylinder 10 due to the vibration caused by the transportation or the movement. The present invention is an excellent invention which can provide a container which is prevented from protruding to the outside, does not require a lock mechanism for it, and is safe even against a rotational load.

FIGS. 10 to 12 show a second embodiment of the present invention. FIG. 10 shows a vertical partial cross-sectional view of the stick-shaped decorative material feeding container 101 in a state where the core chuck member 130 is located at the lower limit. FIG. 11 shows a state in which the core chuck member 130 is at the position of the upper limit. FIG. 13 shows a front cylinder 110 (A) core chuck member 130 (B) used in the second embodiment,

Is a container body 103 having a front cylinder 110 and an outer cylinder 140.
And a core chuck member 130 and an elastic cylinder 160.

As shown in FIG. 12, the core chuck member 13
Reference numeral 0 denotes a cylindrical cosmetic material holding portion 131 having a cavity portion 131a at a front end thereof, and a spiral portion 134 formed of a plurality of convex spirals formed on a rod 132 extending therefrom,
The inner peripheral surface is provided with a through hole in which a plurality of vertical ribs 135 are formed.

The container body 103 includes an outer cylinder 140 having a bar shaft 142 erected from the bottom surface, and an engaging strip 143 is provided on the outer peripheral surface of the bar shaft 142. Elastic cylinder 160
Has a through hole 161 having a diameter smaller than the outer diameter of the spiral portion 134 of the core chuck member 130, and has an engaging portion 168 on the inner peripheral surface.
And a vertical rib 164 is provided on the outer diameter.

The vertical ribs 164 of the elastic cylinder 160 are engaged with the spline engaging portions 115 in the front cylinder 110, and the elastic cylinder 160 is mounted so that the front cylinder 110 cannot rotate.

The inner peripheral surface of the through hole 161 of the elastic cylinder 160 of this embodiment is
An engaging portion 168 in the form of a female screw formed at the same pitch and pitch as the male screw of No. 4 is formed.

The rod-shaped decorative material feeding container 10 of this embodiment will be described below.
1 will be described. When the front cylinder 110 of the stick-shaped cosmetic material feeding container 101 in FIG. 10 is rotated with respect to the container body 103, the core chuck member 13 is provided on the container body 103 side.
The vertical rib 135 of the 0 through hole 136 and the engagement ridge 143 formed on the rod 142 are engaged to form a rotation stopping mechanism.

Further, the engaging portion 168 of the elastic cylinder 160 fixed in the front cylinder 119 and the spiral portion 134 of the core chuck member 130 constitute a screwing mechanism. In response to the rotation, the shaft 13 starts moving in the axial direction, and at the same time, the cavity 13
The stick-shaped decorative material B whose tail is supported by 1a starts to protrude from the front end opening hole 111 of the front cylinder 110, and continues to rotate, so that the lead chuck member 130 moves up as shown in FIG. It is located at the ascending limit in.

The lifting limit of the stick-shaped decorative material feeding container 101 of the second embodiment is determined by the upper end 13 of the decorative material holding portion 131.
1b abuts on the step 116 in the front cylinder 110, but when a rotating load is applied to raise the lead chuck member 130, the rod body 132 of the lead chuck member 130 The engaging portion 168 in the through hole 161 of the elastic cylindrical body 160 is deformed while being engaged with the rod shaft 142 erected from the bottom surface of the cylinder 140, thereby starting idling and preventing damage to the container.

The stick-shaped decorative material feeding container 101 of the second embodiment.
The difference between the rod-shaped decorative material feeding container 1 of the first embodiment and the rod-shaped decorative material A of the first embodiment is that the rod-shaped decorative material A moves forward and backward while the front tube 10 and the rod-shaped decorative material A rotate synchronously. The front cylinder 110 and the rod-shaped decorative material B of the second embodiment are configured such that the rod-shaped decorative material B moves forward and backward while rotating with each other, and that the stopper member 70 is connected to the rear end of the core chuck member 30 in the first embodiment. The upper end surface 70a of the stopper member 70 and the lower end surface of the elastic cylindrical body 60 are brought into contact with each other to limit the upward movement. In contrast to the specification in which the tip of the core chuck member 130 is not brought into contact with the distal end of the core 12, the ascending limit of the core chuck member 130 of the second embodiment is such that the decorative material holding portion 131 can be expected to have a strength with a cylindrical body having a cavity.
The upper end portion 131b is brought into contact with the step portion 116 in the front cylinder 110 so as to limit the upward movement.

Since no stopper member is required,
Effects such as the cost and the number of parts during assembly can be reduced.

As a further feature of this embodiment, the elastic cylinder 1
The relationship between the rod body 132 and the helical portion 134 of the core chuck member 130 with respect to the through hole 161 of 60 and the engaging portion 168 formed on the inner peripheral surface thereof is such that the male screw and the female screw are equal in lead and pitch. Thus, the effect of idle rotation and the like can be obtained even with the usual screw shape.

Further, the elastic cylindrical body 160 is
5 and the outer cylinder fitting portion 166 is inserted so as to rotate relative to the outer cylinder 140 and slide, so that the front cylinder 110 and the outer cylinder 140 are connected to each other. It is possible to reduce backlash between members when rotating relatively, and to impart frictional resistance when rotating the front cylinder and the container body relatively.

The rod body 232 of the elastic cylinder 260 can be easily inserted into the through-hole 261
The idle rotation inside the container releases the overload on the rod-shaped cosmetic material feeding container, thereby preventing breakage and damage.

In this embodiment, like the rod-shaped decorative material feeding container of the first embodiment, the feeding slide is performed by the rod body 2 of the core chuck member 230.
This is an excellent invention which is performed by friction resistance between the elastic member 32 and the elastic cylindrical body 260, and also provides smooth feeding and sliding feeling in this portion.

The rotation stopping mechanism of the present invention is not limited to the mechanism described in each of the above embodiments, but means for rotating the front cylinder and the core chuck member synchronously, or the container body and the core chuck. Any mechanism provided with a means for rotating the member synchronously is included in the mechanism, and thus various mechanisms can be used.
