Abstract

PROBLEM TO BE SOLVED: To stabilized let-out torque, by releasing an elastic projection from the inside of an outer cylindrical member by the action of an O-ring when the O-ring, made of a soft material suck as rubber, which presses the inside of the outer cylindrical member, is mounted to a ringlike groove. SOLUTION: A saucer member 7 is formed so as to hold a rod-like cosmetic 8 and be able to move up and down in an outer cylindrical member 6, a male thread 12 is suspended from the saucer member 7, and a female thread 13 is formed in an inner cylindrical member 2 which helical engages with the male thread 12. A ringlike groove 14 is formed near the elastic projection 5 of the upper part 22 of the inner cylindrical member 2, where is a part covered with the outer cylindrical member 6. When an O-ring 15, made of a soft material such as rubber, which presses the inside of the outer cylindrical member 6 is mounted into the ringlike groove 14, the elastic projection 15 is released from the inside of the outer cylindrical member 6 by the action of the O-ring 15. This constitution stabilizes the let-out torque.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container for lipstick or the like for storing stick-shaped cosmetics such as lipstick.

[0002]

2. Description of the Related Art A conventional container for a lipstick or the like has an inner cylindrical member whose upper portion is formed in a cylindrical shape, and an outer member which covers the upper portion of the inner cylindrical member whose upper end is open but cannot be pulled out. A tubular member, a dish member that supports a stick-shaped cosmetic product such as lipstick and is vertically movable in the outer tubular member, and the dish member is vertically moved by rotating the inner tubular member and the outer tubular member. And an elastic contacting protrusion that is formed in the upper part of the inner cylinder member and elastically contacts the inner surface of the outer cylinder member.

Alternatively, instead of the elastic projection, an O-ring made of rubber or the like is inserted between the upper portion of the inner tubular member and the outer tubular member to stabilize the feeding torque.

[0004]

As a method for stabilizing the delivery torque of a container for lipstick or the like, when elastic projections are used, the number of parts is small, but the delivery torque tends to be unstable. However, when the O-ring is used, the payout torque is stable, but the number of parts increases and the cost of the container increases, which is a conflict.

Further, when both the elastic contact protrusion and the O-ring are used, only the respective defects are revealed.

Therefore, when commercializing, either one of the structures must be selected, and the mold for molding the component and the component are also decided by it, and the other one is produced during the commercialization. It was impossible to change to.

Therefore, two types of molding dies and parts for elastic projections and O-rings are required, and they must be used properly according to the application, which causes a rise in the cost of the product.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
The object is to obtain a storage container such as a lipstick that can be used with either the elastic contact protrusion or the O-ring as a structure for stabilizing the payout torque even if the product is molded with the same mold.

[0009]

[Means for Solving the Problems] By rotating an inner cylinder member and an outer cylinder member to move a tray member up and down, a resilient contact protrusion elastically contacting the inner surface of the outer cylinder member formed in the upper portion of the inner cylinder member. In a container for storing lipstick or the like configured, an annular groove is formed in a portion of the upper portion of the inner tubular member covered by the outer tubular member, and a soft material such as rubber that press-contacts the inner surface of the outer tubular member with the annular groove. When the formed O-ring is mounted, it is possible to cancel the elastic contact of the elastic projection with the inner surface of the outer cylindrical member by the action of the O-ring.

[0010]

When the O-ring is not attached to the annular groove, the elastic contact projection elastically contacts the inner surface of the outer cylindrical member to keep the feeding torque.

Further, when the O-ring is mounted in the annular groove, the O-ring presses the inner surface of the outer cylinder member to act to stabilize the feeding torque.

At this time, the O-ring presses the inner surface of the outer cylinder member and acts so as to push back the elastic projection in the radial direction, so that the elastic projection can be separated from the inner surface of the outer cylinder member. Is acting on.
