Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a bar-shaped cosmetic container.

[Prior Art] As a bar-shaped cosmetic container, there is a container as shown in Utility Model Publication No. 51-9434, in which an inner cylinder is provided inside a rotary operation cylinder so that it cannot rotate relative to the rotation operation cylinder. A sleeve is arranged between the rotary operation cylinder and the rotary operation cylinder so as to be rotatable with respect to the rotation operation cylinder, and a relay cylinder is arranged between the sleeve and the inner cylinder, and the inside of the relay cylinder and the outer surface of the inner cylinder are diametrically arranged. The relay tube rotates in conjunction with the rotation of the rotary operation tube by arranging engaging members that engage with each other, and a spiral groove is provided on the inner surface of the sleeve, and an engagement member that engages with the helical groove on the outer surface of the relay tube. A protrusion is arranged, an inner plate is arranged inside the sleeve, and an elevating rod hanging down from the inner plate is inserted into the relay tube,
A thread in the opposite direction to the spiral groove is provided on the outer surface of this lifting rod, and an engaging member that threads into the thread is arranged on the upper part of the relay tube, and the engagement member is radially engaged with the outer surface of the inner plate and the inner surface of the sleeve. It is known that a guide member is arranged to prevent relative rotation between the inner plate and the sleeve by engagement of the two, whereby the inner plate moves up and down linearly with respect to the sleeve. .

In this bar-shaped cosmetic container, the lifting rod moves up and down while tilting in the radial direction, and the bar-shaped cosmetic stored in the inner tray moves up and down while coming into contact with the inner peripheral surface of the sleeve, so that the tip of the bar-shaped cosmetic is not damaged. It ends up.

Therefore, recently, Utility Application No. 166457 (Sho 61-166457)
-71819) A rod-shaped cosmetic container has been proposed. This container differs from the above container in that the upper part of the relay cylinder has a double inner and outer annular wall, and the elevating rod is inserted into the inside of this inner annular wall, and the engagement rod is threadedly engaged with the thread of the elevating rod. Protrusions are arranged on the inner surface of the inner annular wall. In this container, the inner plate rises smoothly against the sleeve, so
Since the tip of the bar-shaped cosmetic stored in the inner tray is not damaged when it is raised and lowered, the bar-shaped cosmetic does not become difficult to use and its beauty is not impaired.

[Problems to be solved by the invention] However, in the above-mentioned bar-shaped cosmetic container,
When the cap is attached to the sleeve, a person's hand may touch the cap or the rotary operation tube and cause them to rotate relative to each other, in which case the sleeve will also rotate together. For this reason, the bar-shaped cosmetic stored in the inner tray also rises, and the top of the bar-shaped cosmetic comes into contact with the back surface of the top of the cap, damaging the shape of the top.

The object of the present invention is to solve the above-mentioned problems, and to provide a container that does not rattle during operation, allows smooth lifting and lowering of bar-shaped cosmetics, and allows easy attachment and detachment of the cap.

[Means for solving the problems] The rod-shaped cosmetic container according to the present invention has a rotary operation tube 1.

A cap 30 in the form of a closed cylinder is fitted over the sleeve 20 and the inner cylinder 16, and a relay cylinder 40 is disposed between the sleeve 20 and the inner cylinder 16, and the inner cylinder 40 and the outer surface of the inner cylinder 16 engage with each other in the radial direction. An engaging member is disposed so that the relay tube 40 rotates in conjunction with the rotation of the rotary operation tube 10, and a spiral groove 44 is provided on either the outer surface of the relay tube 40 or the inner surface of the sleeve 20.
An engaging protrusion 24 that screws into the spiral groove 44 is disposed on the other side, and the upper part of the relay tube 40 is branched into an annular wall 45, 42 with an inner and outer double wall. At the same time as disposing the plate 50, a lifting rod 60 vertically provided on the inner plate 50 is inserted into the inner annular wall 45, and a thread 66 in the opposite direction to the spiral groove 44 is provided on the outer surface of the lifting rod 60. With,
An engaging protrusion 46 that is threadedly engaged with the thread 66 is disposed on the upper inner surface of the inner annular wall 45, and the sleeve 20 is moved diametrically outward by the diametrical elasticity of the branched annular walls 45, 42. In addition, the lifting rod 60 is pressed inward in the diametrical direction, and the inner plate 50
Guide members that engage with each other in the radial direction are disposed on the outer surface of the inner surface of the sleeve 20 and on the inner surface of the sleeve 20, and the relative rotation between the inner plate 50 and the sleeve 20 is prevented by the engagement between the two, so that the inner plate 50 is prevented from rotating relative to the sleeve 20. The sleeve 20 moves up and down in a straight line, a gap is provided between the outer peripheral surface of the sleeve 20 and the inner peripheral surface of the cap 30, and a protrusion 34 made of a slippery synthetic resin is provided on the inner peripheral surface of the cap 30. are provided continuously in the circumferential direction or are provided scattered in the circumferential direction, and the sleeve 20

[Function] In the rod-shaped cosmetic container according to the present invention, a gap is provided between the outer peripheral surface of the sleeve 20 and the inner peripheral surface of the cap 30, so even if the cap 30 is rotated, the sleeve 20 does not rotate. .

Further, a protrusion 34 is provided in the circumferential direction on either the outer circumferential surface of the sleeve 20 or the inner circumferential surface of the cap 30, and an annular recess 28 that engages with the protrusion 34 is provided on the other. 28 with the protrusion 3
4 is loosely fitted, so that the cap 30 will not be accidentally separated from the sleeve 20 and, by extension, the rotary operation barrel 10. In this case, since the protrusion 34 is made of a synthetic resin having slipperiness, the protrusion 34
Even if the cap 30 is rotated with the outer peripheral surface of the cap 4 in contact with the inner peripheral surface of the recess 28, the protrusion 34 and the recess 28
The slip sleeve 20 does not rotate.

Further, the annular walls 45 and 42, which are bifurcated into inner and outer parts, have elastic force in the diametrical direction. Since these double inner and outer annular walls 45, 42 are interposed between the sleeve 20 and the lifting rod 60, the annular walls 45,
42 presses the sleeve 20 and the lifting rod 60 in the diametrically outward and outward directions, and as a result, the sleeve 20, the relay cylinder 40, and the inner plate 50 are pressed against each other and are integrated, so that there is no wobbling. Therefore, by rotating the rotary operation cylinder 10, the inner plate 50
Since the operator does not feel any wobbling when raising and lowering the container, a rod-shaped cosmetic container using this invention gives an image of a luxury product. Furthermore, since the inner tray 50 does not tilt with respect to the sleeve 20 when the inner tray 50 is moved up and down, the bar-shaped cosmetic stored in the inner tray 50 does not come into sliding contact with the inner circumferential surface of the sleeve 20. Dish 5
0 can be raised and lowered smoothly.

Furthermore, when the inner plate 50 is completely raised (top dead center), the engagement provided on the upper inner surface of the inner annular wall 45 is connected to the lower end of the thread 66 on the outer surface of the lifting rod 60 vertically installed on the inner plate 50. Although the protrusions 46 engage, even in this case, since the inner annular wall 45 can bend radially outward, the engagement protrusions 46 do not get caught.
The middle plate 50 can be lowered easily.

Furthermore, a protrusion 3 made of a synthetic resin having slipperiness
4 to the cap 30 instead of the outer peripheral surface of the sleeve 20.
Since the protrusion 34 is provided on the inner peripheral surface of the sleeve 20, when the cap 30 is removed or installed, even if the cap 30 is slightly inclined to the sleeve 20, the protrusion 34
comes into contact with the outer peripheral surface of the sleeve 20, and the slipperiness of the protrusion 34 allows the cap 30 to be easily attached and detached.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

Reference numeral 10 is a rotary operation tube in the shape of a bottomed cylinder,
It has an annular recess 12 on its upper inner peripheral surface.
A cylindrical inner cylinder 16 is erected on the upper surface of the bottom 14 of the rotary operation cylinder 10, and a longitudinally long protrusion 18, which is an engagement member, is provided on the outer surface of the inner cylinder 16. .

A cylindrical sleeve 20 is inserted between the rotary operation cylinder 10 and the inner cylinder 16. This sleeve 2
0 has an annular protrusion 22 on the outer surface of the lower part, and this protrusion 22 engages with the recess 12, so that the sleeve 20 is rotatable with respect to the rotary operation barrel 10.

A closed cylindrical cap 30 is attached to the sleeve 20. In this case, sleeve 2
A gap is provided between the outer circumferential surface of the cap 30 and the inner circumferential surface of the cap 30, and a gap is also formed between the lower end surface of the cylindrical portion 32 of the cap 30 and the upper end surface of the rotary operation barrel 10. ing. By doing this, even if the cap 30 rotates, the sleeve 20 and the rotary operation barrel 10 do not rotate. Note that normally, the lower end surface of the cylindrical portion 32 of the cap 30 and the rotary operation tube 1
0 has a small area, and even if the cap 30 rotates while the two are in contact, the rotary operation barrel 10 will not rotate. Therefore, the gap between the lower end surface of the cap 30 and the upper end surface of the rotary operation barrel 10 is Not necessarily necessary.

At the lower part of the peripheral wall 32 of the cap 30, a ring with a rectangular cross section made of polyacetal resin (trade name: Jyuracon) is arranged by insert molding. A portion of the ring protrudes inward from the inner peripheral surface of the peripheral wall 32, and this protrusion forms an annular protrusion 34.

An annular recess 28 having a slightly larger cross section than the projection 34 is bored at a location on the outer peripheral surface of the sleeve 20 facing the projection 34 .
A protrusion 34 is loosely fitted in the. By doing so, the cap 30 is detachably and rotatably supported by the sleeve 20. In this case, even if the outer peripheral surface of the protrusion 34 contacts the inner peripheral surface of the recess 28 and the cap 30 rotates, the protrusion 34
The polyacetal resin forming the cap 4 has a coefficient of friction of 0.1 to 0.3 and is slippery, so the cap 30 rotates idly relative to the sleeve 20.

A cylindrical relay tube 40 is arranged between the sleeve 20 and the inner tube 16. A vertically long protrusion 48, which is an engagement member, is arranged on the inner surface of the relay cylinder 40, and this protrusion 48 engages with the protrusion 18 of the inner cylinder 16 in the radial direction. When the tube 10 is rotated, the relay tube 40 is also rotated in the same direction. Relay tube 4
A spiral groove 44 is provided on the outer surface of the sleeve 20, and a spiral groove 44 is provided on the lower inner surface of the sleeve 20.
An engaging protrusion 24 having the same slope is provided, and this engaging protrusion 24 is screwed into the helical groove 44. By doing so, the relay tube 40 moves up or down relative to the sleeve 20 as it rotates.

Inside the annular wall 42 of the relay tube 40, slightly below the upper end, an inner annular wall 45 has a cross section L.
The annular wall 45 and the annular wall 4 are arranged around the annular wall 45.
2 are paired together to form a double inner and outer annular wall.

A bottomed cylindrical inner tray 50 is inserted inside the sleeve 20 above the relay tube 40, and this inner tray 50 stores a bar-shaped cosmetic, such as a lipstick. The outer surface of the inner plate 50 is provided with a longitudinally long protrusion 56 which is a guide member, and the inner surface of the sleeve 20 is also provided with a longitudinally long protrusion 26 which is a guide member. They engage with each other, and the inner plate 50 is prevented from rotating relative to the sleeve 20.

A cylindrical lifting rod 60 is provided on the lower surface of the bottom of the inner tray 50.
is installed vertically, and this lifting rod 60 is inserted into the inside of the inner annular wall 45. A thread 66 having a slope opposite to that of the spiral groove 44 is provided on the outer surface of the lifting rod 60, and an engaging protrusion 4 having the same slope as the thread 66 is provided on the inner surface of the upper part of the annular wall 45.
6 are provided, and these threads 66 and the engaging protrusions 46
are screwed together. By doing this,
The relay tube 40 is moved upwardly relative to the sleeve 20.
When rotates, the elevating rod 60 also rises relative to the relay tube 40.

Since the rod-shaped cosmetic container 1 of this embodiment is constructed as described above, when the sleeve 20 is gripped and the rotary operation tube 10 is rotated, the interior 16 is also rotated in conjunction, so that the protrusions 18 and 48 are engaged. Then, the relay tube 40 rotates in the same direction. When the relay tube 40 rotates, the relay tube 40 raises itself relative to the sleeve 20 and the cylindrical operation tube 10, and also raises the elevating rod 60 and the inner tray 50 relative to itself. In this case, even if the cap 30 or the rotary operation barrel 10 is rotated with the cap 30 attached, a gap is provided between the outer circumferential surface of the sleeve 20 and the inner circumferential surface of the cap 30, and the cap 30 Since the protrusion 34 on the inner circumferential surface of the sleeve 20 is slippery, the sleeve 20 does not rotate and the inner plate 50 does not rise.

Further, the annular walls 45 and 42, which are bifurcated into inner and outer parts, have elastic force in the diametrical direction. Since these double inner and outer annular walls 45, 42 are interposed between the sleeve 20 and the lifting rod 60, the annular walls 45,
42 presses the sleeve 20 and the lifting rod 60 in the diametrically outward and outward directions, and as a result, the sleeve 20, the relay cylinder 40, and the inner plate 50 are pressed against each other and are integrated, so that there is no wobbling. Therefore, by rotating the rotary operation cylinder 10, the inner plate 50
Since the operator does not feel any wobbling when raising and lowering the container, a rod-shaped cosmetic container using this invention gives an image of a luxury product. Furthermore, since the inner tray 50 does not tilt with respect to the sleeve 20 when the inner tray 50 is moved up and down, the bar-shaped cosmetic stored in the inner tray 50 does not come into sliding contact with the inner circumferential surface of the sleeve 20. Dish 5
0 can be raised and lowered smoothly.

Furthermore, when the inner plate 50 is completely raised (top dead center), the lower end of the thread 66 on the outer surface of the lifting rod 60 vertically installed on the inner plate 50 is engaged with the engagement provided on the upper inner surface of the inner annular wall 45. Although the protrusions 46 engage, even in this case, since the inner annular wall 45 can bend radially outward, the engagement protrusions 46 do not get caught.
The middle plate 50 can be lowered easily.

Furthermore, a protrusion 3 made of a synthetic resin having slipperiness
4 to the cap 30 instead of the outer peripheral surface of the sleeve 20.
Since the protrusion 34 is provided on the inner peripheral surface of the sleeve 20, when the cap 30 is removed or installed, even if the cap 30 is slightly inclined to the sleeve 20, the protrusion 34
comes into contact with the outer peripheral surface of the sleeve 20, and the slipperiness of the protrusion 34 allows the cap 30 to be easily attached and detached.

In the above example, the ring made of polyacetal resin was placed by insert molding, but instead of polyacetal resin, polyamide resin (trade name: nylon) may be placed, and instead of insert molding, the ring may be glued to the inner peripheral surface of the cap.

Further, in the embodiment, the protrusion 34 was provided continuously in the circumferential direction, but instead of this,
The arcuate protrusions 34 may be arranged circumferentially and these protrusions 34 may be loosely fitted into the annular recess 28 . In this case, in order to prevent the inner circumferential surface of the cap 30 from coming into contact with the outer circumferential surface of the sleeve 20, it is preferable that three or more arc-shaped protrusions 34 are provided at equal intervals.

[Effect of the invention] In the rod-shaped cosmetic container according to the invention, a gap is provided between the outer peripheral surface of the sleeve and the inner peripheral surface of the cap, and a gap is provided between the outer peripheral surface and the inner peripheral surface of the cap. The sleeve is not rotated even if the cap is rotated because a protrusion made of a synthetic resin having slipperiness is provided and this protrusion is loosely fitted into an annular recess provided on the other side. For this reason, even if a person's hand touches the cap or the rotary operation tube and turns them while the cap is attached to the sleeve, the bar-shaped cosmetic stored in the inner tray will rise and the top of the cap will rise. The cap will not come into contact with the back surface of the top of the cap and lose its shape. In addition, when the container of this invention is operated, there is no wobbling, giving it the image of a high-class product. Moreover, the bar-shaped cosmetic can be smoothly raised and lowered. Furthermore, since the lubricating protrusion is provided on the inner circumferential surface of the cap rather than on the outer circumferential surface of the sleeve, this protrusion comes into contact with the outer circumferential surface of the sleeve when attaching and detaching the cap, making it easy to attach and detach the cap.
