Description

  The present invention relates to a cosmetic container for lipstick or the like for storing cosmetics such as lipstick.

  A conventional cosmetic container such as a lipstick has a cylindrical inner cylinder member formed with an axial slit groove reaching the lower end at the lower part, and a spiral groove formed inside, and a slit groove for the inner cylinder member is formed. A helical member that covers the part that can be rotated but cannot be pulled out, and an engaging pin that engages with the slit groove of the inner cylindrical member and the helical groove of the helical member are formed on the outer surface, so that it can move up and down within the inner cylindrical member The formed plate member and a gutter member that has a lid fitting portion formed on the upper portion and covers the outer periphery of the spiral member so as not to rotate are included.

  However, the conventional container for cosmetics such as lipstick configured as described above is configured so that the slit groove of the inner cylinder member and the spiral groove of the spiral member reach the lower end so that the inner cylinder member and the dish member can be set. Although the tray member falls off during assembly of the container, it is difficult to carry out the operation. In the storage container after assembly, the lower part of the inner cylinder member is hung up so that the tray member does not come out downward. It was necessary to hold down the bottom of the member. For this reason, the overall length of the hook member cannot be increased, and the design is restricted.

  In addition, when the length of the hook member is inevitably long, it is necessary to insert a separate member into the hook member and hold it with a separate member so that the plate member does not come out downward. There is a disadvantage that the cost of another member becomes high.

As an improvement measure, there is an idea of using the locking projection 3c and the positioning slit 4c as disclosed in Japanese Patent Application Laid-Open No. 10-192047. However, in this structure, the locking projection 3c is used to guide the locking projection 3c to the positioning slit 4c. Since the locking projection 3c cannot be raised to the required height, the locking member 3 must be locked with the lower end of the positioning slit 4c so that it does not come out below the guiding tube 4. This is insufficient to lock the projection 3c, and therefore the pan member is easily pulled out of the guide tube by the lowering operation.
Japanese Patent Laid-Open No. 10-192047

  An object of the present invention is to provide a storage container such as a lipstick which is not limited in design or troublesome to be assembled and costly in view of the above-described conventional drawbacks.

  The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

In order to solve the above-mentioned problems, the present invention makes it possible to lock the engaging pin of the plate member to the lower end portion of the slit groove so that the plate member does not slip out downward in the assembled storage container. An introductory groove that forms a pin locking portion and connects the lower end of the inner cylinder member and the lower end of the slit groove so that the engagement pin of the dish member can pass through, and the dish member introduced into the slit groove of the inner cylinder member The locking rib formed on the side surface or the lower surface of the plate member that prevents the rotation of the plate member so that the engaging pin does not go to the introduction groove, and the side that is formed on the inner surface of the inner cylinder member and contacts the locking rib are Use a dish rotation prevention mechanism that has a shape that can prevent rotation by abutting a small protrusion, and a side that does not contact the locking rib has a warm slope shape that allows the locking rib to easily get over the small protrusion. Is the most important feature.

  Since the present invention is configured as described above, the following effects can be obtained.

  (1) It is not necessary to hold down the lower part of the inner cylinder member with the bottom surface of the hook member so that the dish member does not come out downward in the assembled container, and the hook member can be lengthened. Is not constrained.

  (2) There is no need to insert a separate member into the hook member to prevent the dish member from coming out downward even when the hook member is lengthened in design, and the assembly is not cumbersome and costly. .

  (3) Since the plate member does not fall downward even when the bowl member is assembled during the container assembly, the work is facilitated.

For the purpose of preventing the dish member from coming out downward in the storage container after assembly, a pin locking portion is formed at the lower end of the slit groove so that the engagement pin of the dish member can be locked. The introduction groove that connects the lower end of the inner cylinder member and the lower end of the slit groove so that the engagement pin of the member can pass through, and the engagement pin of the dish member introduced into the slit groove of the inner cylinder member does not go to the introduction groove In this way, the locking rib formed on the side surface or the lower surface of the tray member that prevents the rotation of the tray member and the side that contacts the locking rib formed on the inner surface of the inner cylinder member abuts a small protrusion to prevent the rotation. This is realized by providing a dish rotation prevention mechanism having a shape that can be made and a warm slope shape that allows the locking rib to easily get over the small protrusion on the side that does not contact the locking rib .

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
In the first embodiment of the invention shown in FIGS. 1 to 5, reference numeral 1 denotes a cylindrical inner cylinder member which is open at the top and bottom, and this inner cylinder member 1 is mainly made of a metal material and has a shaft center at the lower part thereof. Directional slits 2 are formed.

  Reference numeral 3 denotes a helical member formed in a cylindrical shape that covers the inner cylindrical member 1 but cannot be pulled out, although the portion of the inner cylindrical member 1 where the slit groove 2 is formed is rotatable. A spiral groove 4 reaching the lower end is formed. Various means have been devised for preventing the helical member 3 from coming out of the inner cylindrical member 1, but any means may be used. In the description of the figure, an expansion formed in an annular shape at substantially the center of the inner cylindrical member 1 is possible. The means for making the inner cylinder member 1 impossible to be pulled out by holding the protruding portion 5 with a concave groove 6 formed in the upper portion of the helical member 3 will be described. In addition, since the spiral groove 4 generally used in the structure of the present invention is a left-hand thread, the explanation of the drawings will be also made for the case where the spiral groove 4 is a left-hand thread.

  Reference numeral 7 denotes a dish member which accommodates the bar-shaped cosmetic material 12 and is formed so as to be movable up and down in the inner cylinder member 1. The groove member 2 and the helical member 3 of the inner cylinder member 1 are formed on the lower outer surface of the dish member 7. An engaging pin 8 that engages with the spiral groove 4 is formed, and by rotating the inner cylinder member 1 and the helical member 3, the dish member 7 can be moved up and down within the inner cylinder member 1. The engaging pin 8 of the plate member 7 is formed to have a slightly smaller diameter than the width of the slit groove 2.

A pin locking portion 13 that can lock the engagement pin 8 is formed at the lower portion of the slit groove 2 of the inner cylinder member 1 so as to prevent the dish member 7 from dropping downward. Further, a pin locking portion 13 is provided at the lower end of the slit groove 2 on the side where the engaging pin 8 of the dish member 7 is pressed by the spiral groove 4 of the spiral member 3 when the dish member 7 of the slit groove 2 is lowered (toward the explanation in the figure). Left side) is formed with an introduction groove 14 that connects the lower end of the inner cylindrical member 1 and the slit groove 2 with the dimension of about half the width of the slit groove 2 and leaving the pin locking portion 13. Although dish member 7 is inserted into the inner cylindrical member 1 from the bottom of the inner cylindrical member 1, the engaging pin 8 when its configuration so that it can lead to cut-split groove 2 through the introducing groove 1 4 Has been.
In this description, the pin locking portion 13 is on the side where the engagement pin 8 is pressed by the spiral groove 4 of the helical member 3 (on the left side in the description of the figure), but it may be on the opposite side.

  In the description of the figure, the pin locking portion 13 is described as being formed in a shape that leaves a part of the slit groove 2, but if the pin locking portion 13 is formed, the shape is this. The shape is not limited to this, and any shape can be used, but it is desirable that the shape be substantially the same as the corresponding engagement pin 8.

  9 is a hook member that covers the outer periphery of the spiral member 3 so that it cannot be pulled out and cannot be rotated. Although it is assumed that the fitting member main body 11 is configured, the hook member main body 10 and the fitting member main body 11 may be formed of one component.

  Reference numeral 15 denotes an anti-rotation mechanism. The anti-rotation mechanism 15 prevents rotation of the plate member 7 so that the engaging pin 8 of the plate member 7 introduced into the slit groove 2 of the inner cylinder member 1 does not go to the introduction groove 14. The small projection 16 formed in the inner surface direction on the lower part of the inner cylinder member 1 and the engaging rib 17 formed on the side surface of the plate member 7 corresponding to the small projection 16 are configured. When the dish member 7 is on the lower side, the small protrusion 16 and the locking rib 17 come into contact with each other to prevent the dish member 7 from rotating.

This rotation prevention mechanism 15 but one that acts as described above, when the assembly of the container are those engaging pin 8 is guided into the cut-split groove 2 through the introduction groove 1 4, In that case, it is desirable to have a shape that does not prevent the rotation of the engagement pin 8, and therefore the shape of the small protrusion 16 is a warm slope 19 on the side that does not come into contact with the engagement rib 17. It is good to make it the shape which can get over the small protrusion 16 easily. The same applies to the shape of the locking rib 17. In the explanation of the figure, the inner cylinder member 1 is formed of a metal material, and the side where the locking rib 17 of the small protrusion 16 abuts (the left side in the figure) is made into an edge shape by cutting out a part by pressing, and the opposite The side is a warm slope 19.

  Reference numeral 18 denotes a lid that is detachably fitted to a lid fitting portion formed on the hook member 9.

In the cosmetic container 20 configured as described above, when the container is assembled, the lower part of the inner cylinder member 1 is inserted and set from the upper part of the spiral member 3. Then inserted from the lower portion of the inner cylindrical member 1 and the dish member 7, but the engaging pin 8 of the plate member 7 when it passes through the guide grooves 1 4 enters the cut-split groove 2, the engaging pin 8 at the same time The dish member 7 can be raised by engaging the spiral groove 4 and rotating the inner cylinder member 1 and the helical member 3. Next, the assembly is completed by setting the hook member 9.

  Next, when the plate member 7 is lowered, the engaging pin 8 of the plate member 7 is pressed to the side pressed by the spiral groove 4 of the spiral member 3 (left side in the description of the drawing) when the plate member 7 is lowered. The engaging pin 8 of the plate member 7 descends while being pressed to the side pressed by the spiral groove 4. Then, the engaging pin 8 comes into contact with the pin locking portion 13 and stops. Further, the engagement pin 8 does not rotate to the introduction groove 14 side (right side in the description of the figure) by the action of the dish rotation prevention mechanism 15, and the dish member 7 does not come out of the inner cylinder member 1.

  Next, different embodiments of the present invention will be described. In these descriptions, the same components as those in the first embodiment of the present invention are designated by the same reference numerals and redundant description is omitted.

  In the second embodiment of the invention shown in FIGS. 6 to 8, the main difference from the first embodiment of the invention is a dish rotation prevention mechanism 15A, which serves to lock the dish member 7A. The rib 17A is formed so as to hang down from the bottom of the plate member 7A, and can be brought into contact with the small protrusion 16A of the inner cylinder member 1. The cosmetic container 20A configured in this way may be used. .

  The structure can be shared, and it can be applied to stick cosmetics such as stick foundations and stick eye shadows.
