Description

The present invention is a stick-shaped cosmetic such as eyebrow, eyeliner, lip liner, or lipstick (hereinafter referred to as "stick-shaped cosmetic") that can be retracted by a stick-shaped cosmetic delivery mechanism provided inside the stick-shaped cosmetic. It relates to a dispensing container.

Conventionally, in a stick-shaped cosmetic delivery container in which a stick-shaped cosmetic can be freely retracted, for example, when the stick-shaped cosmetic delivery container is carelessly dropped, the impact or vibration of the stick-shaped cosmetic delivery container prevents the stick-shaped cosmetic from falling off, breaking, or deforming. might give.

Therefore, in order to prevent damage such as falling off, breakage, and deformation of the cosmetic stick due to impact or vibration when dropped, for example, in a feeding container with a front and rear clutch, the cosmetic stick is screwed to a forward/backward shaft having a solid cosmetic at its tip. A proposal has been made in which a compression spring is held together with an annular packing between the tip end face of the spiral tube and the rear end face of the tip tube (see Patent Document 1).

Therefore, even if the feeding container with front and rear clutches is dropped by carelessness, the advancing/retracting shaft having the solid cosmetic at the tip thereof, and the helical cylinder that is screwed to the advancing/retreating shaft and rotates to advance or retract the advancing/retreating shaft. , while compressing the compression spring together with the annular packing.
As a result, the forward movement of the helical cylinder and the compressive action of the compression spring absorb the shock or vibration when the delivery container with the front and rear clutches is dropped, so that the solid cosmetic does not fall off, break, or deform from the advance/retreat shaft. It is possible to prevent damage such as

However, if the shock or vibration when the delivery container with front and rear clutches is dropped becomes extremely large, the shock or vibration cannot be sufficiently absorbed only by the compression of the compression spring, and the solid cosmetic falls off from the advancing/retreating shaft. Damage such as breakage and deformation may occur.

By the way, in the feeding container with the front and rear clutches, after the compression of the compression spring due to the forward movement of the helical tube reaches its limit, the compressed compression spring expands together with the annular packing, and the helical tube returns to its original state together with the annular packing. It returns to the position.
Here, when the compression spring is compressed or expanded, the annular packing prevents the compression spring from being inserted into the spiral tube or the protrusion from being inserted into the compression spring. It is intended to prevent scratches on the protrusions.
Furthermore, the annular packing does not resist compression or extension of the compression spring so that it can efficiently absorb impact or vibration when dropped when the compression spring is compressed, and quickly return to its original length when the compression spring is extended. As such, it is necessary to move forward or backward smoothly.
Therefore, when the shock or vibration at the time of dropping is very large and the amount of compression of the compression spring becomes very large, the expansion of the largely compressed compression spring becomes large and rapid. A large impact or vibration may occur due to the repulsive force, which may cause damage such as falling off, breakage, and deformation.

Japanese Utility Model Publication No. 2-33703

Therefore, in a stick-shaped cosmetic delivery container in which the stick-shaped cosmetic is freely retractable by a stick-shaped cosmetic delivery mechanism provided inside the container, a compression spring is compressed or compressed by an impact or vibration when the stick-shaped cosmetic is dropped. This prevents damage such as falling off, breakage, and deformation of the cosmetic stick due to the repulsive force when the compression spring is expanded.

As the first feature,
Consists of a cap and a stick-shaped cosmetic delivery container main body that allows the cap to be detachably attached,
The rod-shaped cosmetic delivery container main body includes an outer cylinder, a core cylinder that rotates relatively to a fitting cylinder that rotates integrally with the outer cylinder and has an opening at the tip, and a core cylinder that rotates integrally with the outer cylinder. A fitting cylinder that rotates and rotates relative to the core cylinder, and a rod-shaped cosmetic that is provided inside the fitting cylinder and allows the rod-shaped cosmetic described later to be retractable from an opening at the tip of the core cylinder. and a feeding mechanism,
The stick-shaped cosmetic delivery mechanism holds the stick-shaped cosmetic in the front (hereinafter referred to as the "protrusion direction of the stick-shaped cosmetic in the stick-shaped cosmetic delivery container body") and backward (hereinafter referred to as the stick-shaped cosmetic delivery container body). refers to the direction in which the stick-shaped cosmetic is pushed in.), and a female screw portion that rotates integrally with the fitting cylinder and is screwed into the male screw portion of the push rod. It consists of a screw piece that is formed on the peripheral surface and allows the push rod to move forward and backward,
The rod-shaped cosmetic delivery mechanism is slidable in the fitting cylinder in the longitudinal direction of the axis, and is fitted in the space formed by the core cylinder, the inner peripheral surface of the fitting cylinder, and the outer peripheral surface of the threaded piece. Either one of the inner peripheral surface of the cylinder and the outer peripheral surface of the threaded piece holds one or more elastic friction materials that are in close contact with the other, and the outer peripheral surface of the threaded piece is mounted on the inner periphery of the fitting cylinder. An elastic repulsion member is integrally held so as to interlock with the screw piece on either the front or rear side of the elastic friction material that is in close contact between the surface and the outer peripheral surface of the screw piece.
And, based on the above first feature, as a second feature,
One or a plurality of elastic friction materials fixed to one of the inner peripheral surface of the fitting cylinder and the outer peripheral surface of the threaded piece so as to be in close contact with the other is formed as an O-ring,
Furthermore, as a third feature based on the first feature, or as a fourth feature based on the second feature,
In the space formed by the core tube, the inner peripheral surface of the fitting tube, and the outer peripheral surface of the threaded piece, the inner peripheral surface of the fitting tube and the outer peripheral surface of the threaded piece are in close contact with the outer peripheral surface of the threaded piece. The elastic rebound material held either in front or behind the elastic friction material is a compression spring.

Therefore, even if the stick-shaped cosmetic delivery container is inadvertently dropped with the stick-shaped cosmetic facing downward, the screw piece of the stick-shaped cosmetic delivery mechanism may be damaged by an impact or vibration caused by the drop, such as an O-ring as an elastic friction material. And it advances so as to compress, for example, a compression spring as an elastic rebound material.
However, the O-ring as the elastic friction material is fixed to either the inner peripheral surface of the fitting cylinder or the outer peripheral surface of the threaded piece, and is always in close contact with the other to generate frictional force. , the threaded piece moves forward while resisting the frictional force.
As a result, the threaded piece of the stick-shaped cosmetic dispensing mechanism gradually advances, and along with the compression of the compression spring as the elastic rebound material, it reliably damps the impact or vibration when dropped, so that the stick-shaped cosmetic will not fall off. Damage such as breakage and deformation can be reliably prevented.

After the advance of the screw piece in the rod-like cosmetic delivery mechanism reaches its limit, the compression spring as a compressed elastic repulsion member attempts to expand to return to its original length within the fitting cylinder. be.
However, since the O-ring as an elastic friction material is in close contact with either the inner peripheral surface of the fitting cylinder or the outer peripheral surface of the threaded piece against the other to generate frictional force, the compression spring acts as the O-ring. It extends while resisting the frictional force generated by the ring.
As a result, the compressed compression spring gradually expands to its original position together with the threaded piece, and reliably damps the impact or vibration caused by the repulsive force of the compression spring. Damage such as deformation can be reliably prevented.

Note that the aforementioned accidental fall of the stick-shaped cosmetic delivery container is the case where the stick-shaped cosmetic is dropped downward, but conversely, if the stick-shaped cosmetic is dropped upward, the screw head first retreats. The O-ring as the elastic friction material and the compression spring as the elastic repulsion material are stretched in accordance with the pressure, and thereafter the operation is reversed to the above-described case, thereby preventing the stick-shaped cosmetic from coming off, breaking, and deforming. It can surely prevent damage.

Here, the elastic friction material fixed to either the inner peripheral surface of the fitting cylinder or the outer peripheral surface of the threaded piece forming the rod-shaped cosmetic delivery mechanism is required to have excellent friction resistance. It may be NBR (acrylonitrile-butadiene rubber) or the like, and its shape may be, for example, a cylinder or the like in addition to the above-mentioned O-ring.

In addition, as an example of elastic rebound material, a compression spring is given because it can be compressed or expanded by the input of impact or vibration when dropped, but it is another cushioning part that itself can be compressed and expanded. It is a good thing.

On top of that, based on any one of the first feature or the third feature, as the fifth feature,
A single or a plurality of elastic friction projections are integrally formed on either the outer peripheral surface of the threaded piece or the inner peripheral surface of the fitting cylinder forming the rod-like cosmetic delivery mechanism, which elastically adheres to the other. It is a thing.

Therefore, in addition to the technical actions and effects of the first feature or the third feature, either the inner peripheral surface of the fitting tube or the outer peripheral surface of the threaded piece is elastic with respect to the other. Since the elastic friction protrusions are integrally formed on the inner peripheral surface of the fitting cylinder or the outer peripheral surface of the threaded piece, it is possible to simplify the structure of the parts constituting the stick-shaped cosmetic dispensing mechanism and to reduce the number of parts. Therefore, the efficiency of the manufacturing work can be improved and the manufacturing cost can be reduced.

In the present invention, a stick-shaped cosmetic dispensing mechanism is slidable within a fitting cylinder, and an elastic friction material or an elastic material is provided on either the inner peripheral surface of the fitting cylinder or the outer peripheral surface of the threaded piece, and on the other. The friction projection is brought into close contact with the inner peripheral surface of the fitting tube and the outer peripheral surface of the screw piece on the outer peripheral surface of the threaded piece in the space formed by the core tube, the inner peripheral surface of the fitting tube, and the outer peripheral surface of the threaded piece. Since the elastic repulsion material is integrally held so as to interlock with the screw piece on either the front side or the rear side of the elastic friction material that is in close contact with the thread, even if the stick-like cosmetic material is dropped, the stick-like cosmetic material will be delivered. While resisting the frictional force generated by the elastic friction material or the elastic friction projection, the mechanism compresses or expands the compression spring in the fitting cylinder to generate impact or vibration when dropped, or the compression or expansion of the compression spring. Since the impact or vibration due to the repulsive force when expanding or the contractive force when contracting is reliably damped, it reliably prevents damage such as falling off, breakage, and deformation of the cosmetic stick, and can replace a separate elastic friction material. The elastic friction projections are integrally formed on the fitting cylinder or the threaded piece to simplify the part structure and reduce the number of parts, so that the efficiency of the manufacturing work can be improved and the manufacturing cost can be reduced. It has the same effect.

FIG. 1 is an overall vertical cross-sectional view of a stick-shaped cosmetic delivery container that is an embodiment of the present invention. FIGS. 2A to 2C are cross-sectional views schematically showing the sliding state of the stick-shaped cosmetic delivery mechanism when dropping the stick-shaped cosmetic delivery container according to the embodiment of the present invention. FIG. 3 shows (a) a front view and its AA cross-sectional view, (b) a top view, and (c) a modification of the screw piece of the stick-shaped cosmetic delivery mechanism in the stick-shaped cosmetic delivery container according to the embodiment of the present invention. FIG. 4 is a left side view and a right side view in the top view, and (d) a cross-sectional view taken along the line BB in the top view.

an O-ring or an elastic friction projection as an elastic friction material that allows the stick-shaped cosmetic dispensing mechanism to slide within the fitting cylinder and is in close contact with either the inner peripheral surface of the fitting cylinder or the outer peripheral surface of the threaded piece; In the space formed by the core tube, the inner peripheral surface of the fitting tube, and the outer peripheral surface of the threaded piece, on the outer peripheral surface of the threaded piece, there is an elastic force between the inner peripheral surface of the fitting tube and the outer peripheral surface of the threaded piece. Since an elastic rebound material such as a compression spring is integrally held at either the front or the rear of the friction material, even if the cosmetic stick is dropped, the frictional force generated by the O-ring or the elastic friction projection will not occur. Since the compression spring compresses or expands while resisting, the impact or vibration when the stick-shaped cosmetic is dropped, and the impact or vibration caused by the repulsive force or contractive force of the elastic rebound material, such as the compression spring during expansion or contraction It dampens vibrations.

1 and 2 show a stick-shaped cosmetic delivery container 1 that is Embodiment 1 of the present invention, and the stick-shaped cosmetic delivery container 1 includes a cap 2 and a stick-shaped cosmetic container to which the cap 2 is detachably attachable. It is composed of a feed feeding container main body 3.

The rod-shaped cosmetic delivery container main body 3 rotates relative to the outer cylinder 4 and a fitting cylinder 6 which rotates integrally with the outer cylinder 4, and has a core cylinder 5 having an opening 5a at its tip. a fitting cylinder 6 that rotates integrally with the outer cylinder 4 and rotates relative to the core cylinder 5; It consists of a rod-like cosmetic dispensing mechanism 7 which can be retracted from an opening 5a provided at the tip of the cosmetic.

Further, the stick-shaped cosmetic delivery mechanism 7 holds the stick-shaped cosmetic 8 in the front (hereinafter referred to as "protrusion direction of the stick-shaped cosmetic 8" in the stick-shaped cosmetic delivery container main body 3) and backward (hereinafter referred to as In the stick-shaped cosmetic delivery container main body 3, the push rod 9 forms a male screw portion 9a on the outer peripheral surface of the stick-shaped cosmetic delivery container main body 3. It comprises a threaded piece 10 which has a female threaded portion 10a which is screwed into the male threaded portion 9a and which allows the push rod 9 to move forward and backward.

Here, in the stick-shaped cosmetic dispensing mechanism 7, the fitting tube 6 and the threaded piece 10 are engaged with each other on their respective surfaces at the rear in order to transmit rotation. The mating grooves 6a and 10b are engaged with each other, and the screw piece 10 advances or retreats while sliding forward or rearward relative to the fitting cylinder 6. As shown in FIG.
As a result, when the stick-shaped cosmetic delivery container 1 is subjected to impact or vibration when it is dropped, the engaging grooves 6a and 10b of the two do not become disengaged, and the stick-shaped cosmetic delivery mechanism 7 is held by the fitting cylinder 6. It can be advanced or retracted along the axial direction inside.

In addition, in the first embodiment, a locking stepped portion 6b is formed on the inner peripheral surface of the fitting tube 6 to suppress the rearward sliding of the threaded piece 10 of the stick-shaped cosmetic delivery mechanism 7. As shown in FIG.

In addition, in the space formed by the inner peripheral surfaces of the core tube 5 and the fitting tube 6 and the outer peripheral surface of the threaded piece 10, particularly the flange portion 10c provided around the outer peripheral surface of the threaded piece 10, the An O-ring 11 made of an elastic friction material that is in close contact with the inner peripheral surface of the fitting tube 6 is fixed on the outer peripheral surface of the threaded piece 10 , and then the inner surface of the fitting tube 6 is attached to the outer peripheral surface of the threaded piece 10 . A compression spring 12 as an elastic rebound material is attached to the threaded piece 10 via the flange portion 10d of the threaded piece 10 in front of an O-ring 11 as an elastic friction material that is in close contact between the peripheral surface and the outer peripheral surface of the threaded piece 10. 10 is integrally held so as to be interlocked.

The O-ring 11, which is an elastic friction material fixed to the outer peripheral surface of the threaded piece 10, is in close contact with the inner peripheral surface of the fitting cylinder 6 and generates a frictional force. It may be fixed to the inner peripheral surface of the body, and the shape thereof may be, for example, a cylindrical shape.

Since the stick-shaped cosmetic delivery container 1 has the above structure, the use of the stick-shaped cosmetic delivery container 1 is as follows.
That is, when applying the stick-shaped cosmetic 8, after removing the cap 2 from the stick-shaped cosmetic delivery container main body 3 in the stick-shaped cosmetic delivery container 1, the stick-shaped cosmetic delivery container 1 is constructed while gripping the core cylinder 5. By rotating the outer cylinder 4 , the threaded piece 10 rotates in the same direction through the fitting cylinder 6 which rotates together with the outer cylinder 4 .
As a result, the push rod 9 forming the male screw portion 9a to be screwed into the female screw portion 10a of the rotating screw piece 10 advances forward, so that the rod-shaped cosmetic material 8 held in front of the push rod 9 moves forward. It protrudes from the opening 5a at the tip of the cylinder 5. As shown in FIG.

After the application of the stick-shaped cosmetic material 8 is finished, the outer tube 4 constituting the stick-shaped cosmetic delivery container main body 3 is rotated in the opposite direction while gripping the core tube 5, whereby the outer tube 4 and the outer tube 4 are rotated. The threaded piece 10 is reversely rotated in the same direction via the fitting cylinder 6 which rotates integrally.
As a result, the push rod 9 forming the male threaded portion 9a to be screwed into the female screw portion 10a of the rotating screw piece 10 retreats rearward, so that the rod-shaped cosmetic material 8 held in front of the push rod 9 is a core. The cylinder 5 enters through the opening 5a at the tip.

If the stick-shaped cosmetic delivery container 1 is carelessly dropped with the stick-shaped cosmetic 8 facing downward, the following occurs.
That is, if the stick-shaped cosmetic 8 of the stick-shaped cosmetic delivery container 1 is carelessly dropped, the push rod 9 and the screw piece 10 of the stick-shaped cosmetic delivery mechanism 7 are disengaged due to the shock or vibration caused by the drop. It moves forward while sliding forward so as to compress the compression spring 12 together with the O-ring 11 which is an elastic friction material fixed to the outer peripheral surface of the.

Here, the O-ring 11 is in close contact with the inner peripheral surface of the fitting tube 6 to generate a frictional force, and furthermore, in front of the O-ring 11 fixed to the outer peripheral surface of the screw piece 10, the screw piece 10 has a frictional force. Since the compression spring 12, which is integrally held via the flange portion 10d so as to be interlocked with the screw head 10, is compressed, the screw head 10 gradually advances due to the impact or vibration caused by the drop, thereby reliably damping the impact or vibration caused by the drop. Thus, it is possible to reliably prevent damage such as drop-off, breakage, and deformation of the cosmetic stick 8 .

Further, after the screw piece 10 reaches its limit of advancing, the compressed compression spring 12 tries to expand to its original length until it reaches the locking step portion 6b of the fitting cylinder 6, but the O-ring 11 does not. Since it is always in close contact with the inner peripheral surface of the fitting cylinder 6 and generates a frictional force, the compressed compression spring 12 integrally held with the O-ring 11 via the flange portion 10d expands gradually. becomes.
As a result, the compressed compression spring 12 is gradually extended to its original position together with the threaded piece 10, and the impact or vibration caused by the repulsive force of the compression spring 12 is reliably damped. Also, damage such as deformation can be reliably prevented.

Note that the stick-shaped cosmetic delivery container 1 falls due to carelessness when the stick-shaped cosmetic 8 is dropped downward. Conversely, when the stick-shaped cosmetic 8 is dropped upward, Along with the retraction of the screw piece 4, the O-ring 11 as an elastic friction member and the compression spring 12 as an elastic repulsion member are extended. By operating, it is possible to reliably prevent damage such as drop-off, breakage, and deformation of the cosmetic stick 8 .

Further, the threaded piece 10 of the stick-shaped cosmetic delivery mechanism 7 provided in the stick-shaped cosmetic delivery container 1 of the first embodiment holds the O-ring 11, which is the elastic friction material, on the outer peripheral surface of the threaded piece 10. On the other hand, since frictional force is generated by being in close contact with the inner peripheral surface of the fitting cylinder 6, the outer peripheral surface of the threaded piece 10' has an elastic friction that is in close contact with the inner peripheral surface of the other fitting cylinder 6. The protrusion 11' may be integrally formed.

That is, as shown in FIGS. 3(a) to 3(d), a modification 10' of the screw piece 10 of the first embodiment has a substantially cylindrical shape as a whole, and a push rod 9 is provided on the front inner peripheral surface thereof. A female threaded portion 10a' is formed to be screwed into the male threaded portion 9a on the outer peripheral surface. The four ribs 13 are formed along the axial direction at positions orthogonal to each other, and two slits are arranged in parallel in the axial direction at positions facing each other along with the flange portion 10d' at the substantially central portion. A plurality of elastic frictional projections 11', 11' are formed which elastically adhere to the inner peripheral surface of the fitting cylinder 6 by being sandwiched between them.

Here, the screw piece 10' has four ribs 13 and two slits 14, 14 arranged side by side, so that the two elastic friction protrusions 11', 11' are brought into close contact with the inner peripheral surface of the fitting tube 6. By generating a frictional force, the stick-shaped cosmetic delivery container main body 3 is fixed in the fitting cylinder 6 .
Therefore, when the fitting tube 6 is rotated, the threaded piece 10' rotates integrally with the inner peripheral surface of the threaded piece 10' due to the frictional force generated between the threaded piece 10' and the female threaded portion 10a of the threaded piece 10'. A push rod 9 having a male threaded portion 9a screwed to ' advances or retreats, and the rod-like cosmetic material 8 moves freely into and out of an opening 5a at the tip of the core tube 5. As shown in FIG.

Similarly to the stick-shaped cosmetic delivery container 1 of the first embodiment, if the stick-shaped cosmetic 8 is dropped downward by carelessness, the following occurs.
That is, if the stick-shaped cosmetic delivery container 1 is dropped carelessly, even if the stick-shaped cosmetic 8 in the stick-shaped cosmetic delivery container 1 is dropped downward, the rib 13 will be damaged by the impact or vibration at the time of dropping. At the same time that the frictional force is lost, the threaded piece 10' of the stick-shaped cosmetic delivery mechanism 7 is pushed together with the push rod 9 by the elastic friction projection 11' integrally formed on the outer peripheral surface of the threaded piece 10' and the inside of the fitting cylinder 6. It advances while sliding so as to compress the compression spring 12 against the frictional force due to the close contact with the peripheral surface.

Here, the elastic friction projection 11' is in close contact with the inner peripheral surface of the fitting tube 6 to generate a frictional force, and is held between the elastic friction projection 11' and the rear end surface of the core tube 5. Since the compression spring 12 is compressed, the screw piece 10 gradually advances due to the impact or vibration at the time of dropping, thereby reliably damping the impact or vibration at the time of dropping. Damage such as breakage and deformation can be reliably prevented.

Further, after the screw piece 10' reaches its limit of advancing forward, the compressed compression spring 12 tries to expand to its original length until it reaches the engaging stepped portion 6b of the fitting tube 6, but the elastic friction projection does not reach its original length. 11' and the inner peripheral surface of the fitting tube 6 are always in close contact with each other to generate frictional force, so the compressed compression spring 12 gradually expands.
As a result, the compressed compression spring 12 is gradually extended to its original position together with the screw piece 10', and the impact or vibration caused by the repulsive force of the compression spring 12 is reliably damped. Damage such as breakage and deformation can be reliably prevented.
