Description

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

  A conventional storage container such as a lipstick has a cylindrical inner cylinder member in which a pair of axially-grooved grooves are formed on the lower surface, and a portion in which a spiral groove is formed and the inner groove is formed. A helical member that can rotate but cannot be pulled out, and a pair of engaging pins formed on the outer surface that engage with the slit groove of the inner cylindrical member and the helical groove of the helical member, and move up and down in the inner cylindrical member The plate member is formed so as to be able to be formed, and the lid member is formed on the upper portion, and the collar member covers the outer periphery of the spiral member so as not to rotate.

  However, the conventional storage container such as a lipstick configured in this way 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. However, in order to prevent the dish member from coming down downward in the assembled storage container, it is necessary to press the lower part of the inner cylinder member with the bottom surface of the hook member, so that the length of the hook member is reduced. The design could be restricted because it could not be made longer.

  For this reason, when the length of the hook member is inevitably increased, it is necessary to insert another member into the hook member and press the bottom surface of the plate member with the separate member so that the plate member does not come out downward. There is a disadvantage that the cost increases as the number of members increases.

As an improvement measure, the present applicant has previously filed Japanese Patent Application No. 2003-192865 (Japanese Patent Application Laid-Open No. 2005-27708). Even in this invention, a pair of slit grooves formed in the lower portion of the inner cylinder member is formed. However, there is no idea that one of the slit grooves is configured as a drop-off preventing groove and the other slit groove is configured as an anti-rotation split groove. there were. Therefore, in this invention, it becomes a structure where main components concentrate on one slit groove. As a result, the dimensional management was severe and the production was troublesome.

  An object of the present invention is to provide a storage container such as a lipstick in which the design is not limited and the size management and assembly are troublesome and the production cost is not high.

  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 problem, in the present invention, in order to prevent the dish member from slipping out downward, one lower part of the slit groove of the inner cylinder member is pressed by the spiral groove when the dish member is lowered. By forming an engagement pin locking portion that can lock the engagement pin of the dish member in the lower part on the side, the dish member is prevented from falling off from the lower part of the inner cylinder member and the engagement pin is lowered when the dish member is lowered On the side that is not pressed by the spiral groove, it is configured as a drop-off prevention slit groove that forms an introduction groove through which the engagement pin can pass, and the lower part of the other inner cylinder member split groove reaches the lower end of the inner cylinder member. Engagement of the plate member when the engagement pin of the plate member is in a position locked by the engagement pin locking portion of the drop-off preventing slit groove on the side where the engagement pin is not pressed by the spiral groove when the plate member is lowered Abutting the pin Therefore the most important feature be configured as a rotation preventing cut-split groove formed an engaging pin rotation preventing portion capable of preventing the rotation of the disc member.

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

  Even if the slit groove of the inner cylinder member and the spiral groove of the spiral member are configured to reach the lower end so that the inner cylinder member and the dish member can be set, the dish member is lowered downward in the assembled storage container. Since it is configured so as not to come out, the overall length of the hook member cannot be increased and the design is not restricted.

  Even when the hook member is lengthened, it is not necessary to insert another member into the hook member so as to prevent the dish member from coming out downward, and the assembly is troublesome and the production cost is not high.

  In addition, since one slit groove does not have both fall-off prevention and rotation prevention, it is not a structure in which the main components are concentrated in one slit groove, which makes dimension management and production easy. Become.

For the purpose of preventing the dish member from slipping downward in a storage container such as a lipstick , one lower part of the slit groove of the inner cylinder member is on the side where the engagement pin is pressed by the spiral groove when the dish member is lowered. By forming an engagement pin locking portion that can lock the engagement pin of the dish member in the lower part, the dish member is prevented from falling off from the lower part of the inner cylinder member, and the engagement pin spirals when the dish member is lowered. The side that is not pressed by the groove is configured as a drop-off prevention slit groove that forms an introduction groove through which the engagement pin can pass, and the lower part of the other inner cylinder member's slit groove reaches the lower end of the inner cylinder member and is a dish member On the side where the engagement pin is not pressed by the spiral groove when descending, when the engagement pin of the countersink is in a position locked by the engagement pin locking part of the drop-off prevention slit groove, By touching Was realized by the construction as a rotation preventing cut-split groove is formed engaging pin rotation preventing portion capable of preventing the rotation of the disc member Te.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
In the embodiment of the invention shown in FIGS. 1 to 5, reference numeral 1 denotes a cylindrical inner cylinder member that is open at the top and bottom, and two axially split grooves 2 are formed in the lower portion of the inner cylinder member 1 on the opposite side. Has been.

  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.

  7 is a dish member which accommodates the cosmetics 19 and is formed so as to be movable up and down in the inner cylinder member 1. On the lower outer surface of the dish member 7, the slit groove 2 and the helical member 3 of the inner cylinder member 1 are formed. A pair of cylindrical engaging pins 8 that engage with the spiral groove 4 are formed on opposite sides, and the dish member 7 can be moved up and down within the inner cylinder member 1 by rotating the inner cylinder member 1 and the helical member 3. Yes. 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.

  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. In the description of the figure, the hook member 9 is formed with a hook member main body 10 and a lid fitting portion fixed to the upper part thereof. The joint member body 11 is not limited to this, but the hook member 9 may be formed of the hook member body 10 and the fitting member body 11 as one component.

  Reference numeral 12 denotes a dish dropout prevention mechanism. This dish dropout prevention mechanism 12 is configured by forming one of the two slit grooves of the inner cylinder member 1 as a dropout prevention slit groove 13 and forming the other as a rotation prevention slit groove 14. ing.

  An engagement pin locking portion 15 is provided on the lower portion of the drop-off preventing slit groove 13 from one side, and on the side where the engagement pin 8 is pressed by the spiral groove 4 when the plate member 7 is lowered (left side in the description of the figure). The engaging pin locking portion 15 is formed on the side surface, and contacts the engaging pin 8 on one side of the plate member 7 when the plate member 7 is about to come out from below the inner cylinder member 1. The member 7 acts so as not to slip out below the inner cylinder member 1. That is, this position becomes the bottom dead center for the dish member 7, and the dish member 7 does not go below the bottom dead center in normal use.

  Further, an introduction groove 16 through which one engagement pin 8 of the plate member 7 can pass is formed on the side where the engagement pin locking portion 15 of the drop prevention slit groove 13 is not formed, and an upper portion of the drop prevention slit groove 13. Are formed at positions deviated from the same line. When the storage container 20 such as a lipstick is assembled, the engaging pin 8 of the plate member 7 passes through the introduction groove 16 so that the inner cylindrical member 1 It is configured so that it can be guided to.

  If the engagement pin 8 and the engagement pin locking portion 15 are in contact with each other by the action of the drop-off preventing slit groove 13 as described above, the dish member 7 will not be pulled out below the inner cylinder member 1. If the plate member 7 rotates in the inner cylinder member 1 and the engagement pin 8 moves to the introduction groove 16, the engagement pin 8 and the engagement pin locking portion 15 do not come into contact with each other. The member 7 falls off from the inner cylinder member 1.

  In order to prevent this, an anti-rotation split groove 14 formed in the split groove 2 on the opposite side to the drop-off preventive split groove 13 of the inner cylinder member 1 is provided. The inner pin 1 reaches the lower end of the inner cylinder member 1 and is opened. An engagement pin rotation preventing portion 17 is formed on the side where the engagement pin 8 is not pressed by the spiral groove 4 when the dish member 7 is lowered. The side wall of the engagement pin 8 on the prevention slit groove 14 side abuts against the engagement pin rotation prevention portion 17 to prevent the plate member 7 from rotating when the plate member 7 is at the bottom dead center. The engagement pin 8 of the plate member 7 on the prevention slit groove 13 side is configured not to rotate in the direction of the introduction groove 16.

  However, even if one of the engaging pins 8 of the plate member 7 is positioned at a position where it is introduced into the introduction groove 16 when assembling the storage container 21 such as a lipstick, the introduction groove 16 is not separated from the drop-off prevention slit groove 13. Is formed at a position shifted from the same line, the other engagement pin 8 does not come to the position where it is introduced into the rotation prevention slit groove 14, and the dish member 7 is inserted into the inner cylinder member 1. Will not be able to.

  Therefore, the dish member 7 can be inserted into the inner cylinder member 1 at a position corresponding to the introduction groove 16 of the drop-off preventing slit groove 13 at the lower end portion of the rotation preventing slit groove 14 on the engagement pin rotation preventing portion 17 side. A notch 18 is formed in this manner, and the notch 18 is engaged with the engaging pin locking portion 15 of the drop-off preventing slit groove 13 from the lower surface of the inner cylinder member 1. It is formed up to a position where it can be stopped, that is, a position at which the engagement pin 8 of the drop-off preventing slit groove 13 can be prevented from moving in the direction of the introduction groove 16 at the bottom dead center of the plate member 7 that moves up and down in the inner cylinder member 1. I'm.

  Reference numeral 19 denotes a lid that is detachably fitted to a lid fitting portion formed on the hook member 9.

  In the cosmetic container 21 configured as described above, when the cosmetic container 21 is assembled, the lower part of the inner cylinder member 1 is inserted and set from the upper part of the spiral member 3. Next, the dish member 7 is inserted from the lower part of the inner cylinder member 1. At this time, the engaging pin 8 of the dish member 7 abuts against the notch 18 and pushes the width of the slit groove 2 to widen the dish member. The engaging pin 8 enters the slit groove 2 and simultaneously the engaging pin 8 engages with the spiral groove 4 to rotate the inner cylinder member 1 and the helical member 3, thereby allowing the dish member 7 to move to the inner cylinder member. It becomes possible to move up and down within 1. Next, the assembly is completed by setting the hook member 9.

  Since it is realized by modifying the structure of the conventional product, it can be easily applied to other cosmetic storage containers or the like as long as it is a pay-out type container having the same structure.
