Description

The present invention relates to a stick-shaped cosmetic product storage container for storing a stick-shaped cosmetic product.

A conventional stick-shaped cosmetics storage container has a cylindrical inner tubular member formed so that a slit groove in the axial direction communicates with a lower end portion of the conventional cosmetic container, and a slit formed in the inner tubular member. Inside the inner cylinder member, a spiral member that covers the portion where the groove is formed is rotatable but cannot be slipped out, and an engaging pin that engages with the slit groove of the inner cylinder member and the spiral groove of the spiral member is formed on the outer surface. The tray member is formed so as to be movable up and down, and the hakama member which is provided with a lid fitting portion on the upper portion and non-rotatably covers the outer periphery of the spiral member.

However, in the conventional stick-shaped cosmetics storage container configured in this way, the lower end of the dish member was positioned by bringing the lower surface of the dish member into contact with the inner surface of the hakama member. If the length of the tray member changes, the length of the tray member must be changed accordingly, and the die of the tray member must be modified accordingly, which is uneconomical.

As a remedy for this problem, the applicant of the present application is Japanese Patent Application No. 2006-117831, which is a stick-shaped cosmetic container such as lipstick, in which one of the slits of the inner tubular member is engaged with an engaging pin of the dish member when the dish member is lowered. Therefore, the dish member is configured as a drop-prevention slit groove in which an engagement pin locking portion is formed to prevent the dish member from falling off the lower portion of the inner cylinder member, and the slit groove of the other inner cylinder member is formed as the engagement pin of the dish member. Anti-rotation part that prevents rotation of the dish member by abutting the engagement pin of the dish member when it is in a position where it is locked by the engagement pin locking portion of the drop-prevention slit groove We have applied for a structure that eliminates the restriction of the design and cost by preventing the dish member from slipping out downward as a slit groove.In this structure, the slit groove of the inner cylinder member is set as a pair. It had to be constructed, and it took time to process.

In addition, Japanese Patent No. 4283676 has a rotating cylinder, a sleeve, and an inner tray that can be filled with stick-shaped cosmetics, and a small protrusion provided on the inner tray is guided by an inner tray guide groove provided on the sleeve to rotate. A stick-shaped cosmetics container including an internal structure capable of moving the small protrusions up and down by a screw cut on the inner surface of a cylinder and allowing the stick-shaped cosmetics filled in the inner dish to appear and disappear. The inner dish guide groove provided on the sleeve in the body is composed of a straight main groove whose lower end is closed, and a sub groove which branches off from the middle of the main groove and has a substantially inverted J-shape whose lower end is open. At the same time, the main groove has been invented a stick-shaped cosmetic container, characterized in that it has a linear main groove lowermost part for accommodating the small projection movably only in the vertical direction. By providing the small projection 6 with the resistance portion 16 as shown in FIG. 9 in advance, it is possible to prevent the small projection 6 from accidentally entering the sub groove 4b. When the resistance portion 16 is provided on the small protrusion 6, it is preferable to make the length x from the upper end of the small protrusion 6 to the lower end of the resistance portion 16 longer than the width of the inlet portion 4c because the prevention effect becomes large. However, even if it is possible to prevent the small protrusion 6 from accidentally entering the sub groove 4b by such a structure, when the inner plate comes to the lowest point position, the resistance portion becomes the main groove maximum. Since it comes below the lower part, the resistance part sneaks into the inside of the rotary cylinder and presses the inner tray and the rotary cylinder, causing an abnormal value in the rotational torque. As a result, the rotating torque when putting in and out the stick-shaped cosmetic product cannot be made uniform throughout the entire process, and the quality deteriorates, resulting in a decrease in commercial value.

The problem to be solved is to provide a stick-shaped cosmetic container that does not restrict design, does not require complicated manufacturing due to dimensional control and assembly, and does not cause abnormal values in rotation torque. is there.

According to the present invention, the lower end of the slit groove of the inner cylinder member is closed so that the engaging pin of the dish member can be locked, and further the introduction groove that communicates laterally from the lower end of the slit groove to the lower end portion of the inner cylinder member. When the engaging pin of the dish member reaches the lower end of the slit groove by contacting the slit groove on the side where the introduction groove is formed, the engaging pin of the dish member is formed above the engaging pin of the dish member. An anti-rotation part is formed to prevent entry into the introduction groove, and the upper part of this anti-rotation part spreads the inner cylinder member when the engaging pin is in the introduction groove when setting the dish member to the inner cylinder member. The anti-rotation part is formed as an inclined surface that reduces in diameter upward so that it can slip inside the inner cylinder member, and the upper part of the slit formed in the inner cylinder member is when the dish member reaches the top dead center. The main feature is that the anti-rotation portion of the dish member is formed to a position where it can remain in the slit groove .

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

The present invention has the following effects.

In the storage container after assembly, since the dish member does not slip out below the inner cylindrical member, the total length of the hook member cannot be increased, and the design is not restricted. ..

Since the anti-rotation portion is formed above the engagement pin, it is always located in the slit groove and does not sneak into the inner tubular member during normal use. Therefore, the rotational torque when the cosmetics are taken in and out can be made uniform throughout the entire process without affecting the rotational torque value of the delivery, and the quality is stable and the commercial value can be increased.

For the purpose of constructing the storage container after assembly so that the dish member does not come out downward, the lower end of the slit groove of the inner tubular member is closed so that the engaging pin of the dish member can be locked, and An introduction groove is formed so as to communicate laterally from the lower end of the slit groove to the lower end portion of the inner tubular member, and the upper portion of the engaging pin of the dish member is in contact with the slit groove on the side where the introduction groove is formed. A rotation preventing portion is formed to prevent the engagement pin from entering the introduction groove when the engagement pin of the dish member reaches the lower end of the slit groove. When the engaging pin is in the introduction groove when setting, the inner cylinder member is expanded and the rotation prevention part is formed as an inclined surface that is reduced in diameter upward so as to be able to sneak into the inner cylinder member. The upper part of the slit groove formed in the member is realized by being formed to a position where the rotation preventing portion of the pan member can stay in the slit groove when the pan member reaches the top dead center .

In the first embodiment of the invention shown in FIGS. 1 to 5, reference numeral 1 is a cylindrical inner cylinder member having upper and lower openings, and a slit groove 2 is formed in the lower part of the inner cylinder member 1 in the axial direction. Has been done.

Reference numeral 3 denotes a helical member formed in a tubular shape that can rotate the portion of the inner tubular member 1 where the slit groove 2 is formed, but covers the inner tubular member 1 in a slip-out manner. Has a spiral groove 4 reaching the lower end. Various means have been devised as a method for preventing the spiral member 3 from slipping out of the inner cylinder member 1, but any means may be used. In the explanation of the drawings, an expansion formed in an annular shape in the substantially central portion of the inner cylinder member 1. A means for making the inner cylinder member 1 unable to slip out by holding the projecting portion 5 by the concave groove 6 formed in the upper portion of the spiral member 3 will be described. Further, since the spiral groove 4 that is generally used in the structure of the present invention is a left-handed screw, the description of the drawings will also be made assuming that the spiral groove 4 is a left-handed screw.

Reference numeral 7 denotes a dish member which accommodates the cosmetic material 20 in an upper part and is formed in the inner tubular member 1 so as to be movable up and down. On the lower outer surface of the dish member 7, the slit groove 2 and the spiral of the inner tubular member 1 are formed. A cylindrical engagement pin 8 that engages with the spiral groove 4 of the member 3 is formed, and by rotating the inner cylinder member 1 and the spiral member 3, the dish member 7 can be moved up and down within the inner cylinder member 1 to make up. The material 20 is retracted from the upper end surface of the inner tubular member 1. The engagement pin 8 of the dish member 7 is formed to have a diameter slightly smaller than the width of the slit groove 2.

Reference numeral 9 denotes a hook member that covers the outer periphery of the spiral member 3 so as not to slip out and not turn. The hook member 9 is a fit member in which a hook member body 10 and a lid fitting portion fixed to the upper portion are formed in the description of the drawings. Although the composite member main body 11 is used, the present invention is not limited to this, and the separate member main body 10 and the fitting member main body 11 may be formed as one component.

Reference numeral 12 denotes a tray slip-out prevention mechanism. The tray slip-out prevention mechanism 12 includes a rotation prevention portion 13 and a slit groove 2 formed above the slit groove 2 of the inner cylinder member 1 and the engaging pin 8 of the tray member 7. The lower surface of the slit groove 2, which is formed by closing the lower end of the slit groove 2 at the lower end, and locks the engaging pin 8 to prevent the dish member 7 from falling below the inner tubular member 1, It is configured by an introduction groove 16 that communicates from the side surface of the groove lower end surface 15 to the lower end of the inner tubular member 1.

Since the introduction groove 16 is formed so as to reach from the side surface of the lower end surface 15 of the slit groove to the lower end of the inner tubular member 1, the width thereof is set when the dish member 7 is set on the inner tubular member 1. The engaging pin 8 is configured so that it can pass through the introduction groove 16 and reach the slit groove 2 of the inner cylinder member 1.

The anti-rotation portion 13 of the dish member 7 is always located in the slit groove 2 during normal use, and is configured to have a height that does not project to the outside from the outer peripheral portion of the inner tubular member 1 and the spiral member 3. The side surface of the slit groove 2 on the side where the introduction groove 16 is formed (the right side in the description of the drawings) is always formed by the side surface of the slit groove 2 of the inner tubular member 1 on the same side. It is prevented from rotating.

Further, the rotation preventing portion 13 of the dish member 7 is located when the engaging pin 8 of the dish member 7 is in contact with the lower end surface 15 of the slit groove 2 of the slit groove 2, that is, when the dish member 7 is at the lowest point. The engagement pin 8 can not enter into the introduction groove 16 without being able to prevent rotation in the direction of the introduction groove 16 that communicates with the slit groove 2 . The plate member 7 is prevented from rotating by reaching the uppermost position and coming into contact with the side of the slit groove 12 where the introduction groove 16 is formed.

Originally, in the case of such a structure, when the dish member 7 is set in the content member 1, even if the rotation preventing portion 13 reaches the upper end portion in the introduction groove 16 in the introduction groove 16, the engagement pin 8 does not reach the lower end of the slit groove 2 and the engaging pin 8 of the dish member 7 cannot be guided to the slit groove 2, but the upper side of the rotation preventing portion 13 is reduced in diameter upward. When the dish member 7 is set on the inner cylindrical member 1 during container assembly, the engaging pin 8 first rises in the introduction groove 16, and the rotation preventing portion 13 reaches the upper end of the introduction groove 16. When it reaches, the inclined surface 18 spreads the inner cylinder member 1 and sunk into the inner cylinder member 1. Then, when the engagement pin 8 reaches the upper end of the introduction groove 16, it is guided to the slit groove 2 and thereby rotated. The prevention portion 13 is also configured to be disengaged from the submergence of the inner tubular member 1 and to be accommodated in the slit groove 2, so that when the engagement pin 8 passes through the introduction groove 16, the rotation prevention portion 13 becomes an obstacle. Absent.

A spiral groove 4 reaching the lower end is formed inside the spiral member 3, but the upper end thereof is configured as a closed spiral groove upper end surface 19, and the engaging pin 8 of the dish member 7 is formed by the spiral groove upper end surface. By coming into contact with 19, the rise of the dish member 7 is stopped. That is, the dish member 7 does not go above this position.

Further, when the dish member 7 is at this position, that is, at the top dead center , the inclined surface 18 of the rotation preventing portion 13 sneaks into the upper end portion of the slit groove 2 and causes an abnormal value in the rotation torque. Even when the member 7 is at this top dead center , the length above the slit groove 2 is determined so that the inclined surface 18 of the rotation preventing portion 13 is still inside the slit groove 2, and the rotation preventing portion 13 is It is configured so as not to sneak into the member 1.

Reference numeral 14 is a lid that is detachably fitted to a lid fitting portion formed on the hook member 9.

In the cosmetic storage container 21 configured as described above, when the cosmetic storage container 21 is assembled, the lower part of the inner tubular member 1 is inserted from the upper part of the spiral member 3 and set. Next, the dish member 7 is inserted from the lower part of the inner cylinder member 1 by aligning the engaging pin 8 and the introduction groove 16 and further aligning with the spiral groove 4, and at that time, the rotation preventing portion of the dish member 7 is inserted. The slanted surface 18 of 13 together with the anti-rotation portion 13 sneaks into the inner surface of the inner tubular member 1 for a moment. Further, when the dish member 7 is pushed in or the engagement pin 8 is rotated in the direction toward the slit groove 2, the engagement pin 8 is guided into the slit groove 2. When the dish member 7 reaches this position, the rotation preventing portion 13 that has been submerged in the inner tubular member 1 is also guided out into the slit groove 2 out of the submerged portion to rotate the inner tubular member 1 and the spiral member 3. As a result, the dish member 7 can be vertically moved within the inner tubular member 1 during normal use. Next, the hook member 9 is set on the spiral member 3 to complete the assembly.

Next, different embodiments of the invention will be described.
In the second embodiment shown in FIGS. 6 and 8, the main differences from the first embodiment are the slit groove 2a of the inner cylinder member 1a, the engagement pin 8a of the dish member 7a, and the rotation preventing portion 13a. The engaging pin 8a of the plate member 7a and the rotation preventing portion 13a located slightly to the right of the engaging member 8a are configured so that the width thereof is slightly smaller than the width of the slit groove 2a. In the configured cosmetics storage container 21a, the engagement pin 8a and the rotation preventing portion 13a separately prevent the dish member 7a from rotating, and the stick-shaped cosmetics storage container 21a thus configured may be used.

The uppermost point position of the dish member 7a of the bar-shaped cosmetics storage container 21a configured as described above can be determined by the upper end surface 17 of the slit groove with which the engaging pin 8a of the tray member 7a and the upper portion of the slit groove 2a abut. It is preferable that the slits 2a be formed further upward with a width such that the rotation preventing portion 13a of the dish member 7a does not slip into the inner cylindrical member 1a. In the case of this structure, the upper surface 19 of the spiral groove of the spiral member 3 does not play its role.

As described above, the present invention is constructed by modifying the structure of the conventional product, and therefore, as long as it is a pay-out type container having the same structure, it can be easily applied to other cosmetic storage containers.
