JP3911115B2 - Bar-shaped member feeding container - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding container capable of exposing an appropriate amount of a rod-shaped member such as lipstick, lip balm, and stick glue depending on the use situation, and in particular, at the time of cooling that occurred when filling the container with the rod-shaped member. It is intended to advantageously avoid quality defects caused by the occurrence of cracks and nests accompanying solidification shrinkage.
[0002]
[Prior art]
A feeding member for a rod-shaped member typified by lipstick or the like usually has a hollow case body having an opening for exposing the rod-shaped member at the tip, a hollow base member for holding the case body, a case body and a base A structure is known in which a rod-shaped member is held inside the member, and the rod-shaped member is linearly moved along the axis of the case body by the rotation of the base member and exposed from the opening. As a moving mechanism of the slider by the rotation of the base member, a spiral groove provided on the inner circumferential surface of the base member and a dowel adapted to the spiral groove are employed.
[0003]
In this type of feeding container, in order to load the rod-shaped member, a plug type that inserts a pre-molded crimson into the case body and a relatively high temperature fluid that is the raw material of the rod-shaped member are poured into the case body. , It can be roughly classified into a filling type which is molded into a desired shape by cooling and solidifying it.
There are two types of filling-type containers: a type that is equipped with a red type called Ojib at the case body opening and filling from the bottom of the container, and a type in which red is poured from the case body opening. In all types, the fluid contracts during the cooling process. In particular, in the case of the type that is filled from the opening of the case body, there is a difference in the cooling rate at the boundary area between the part held by the slider and the part that is not, so the occurrence of nests that cause quality defects at that part is inevitable. In addition, since the slider moves only by rotating the base member, a tensile stress is applied to the rod-shaped member depending on the contraction state during solidification, and cracks that cause breakage may occur. Therefore, the solution is desired.
[0004]
The subject of this invention exists in the place which eliminates the malfunction which had arisen when filling the contents in the delivery container of the rod-shaped member as mentioned above.
[0005]
[Means for Solving the Problems]
The present invention relates to a hollow case main body having an opening at the tip, a hollow base member that holds the case main body and is rotatable separately in the clockwise direction and in the counterclockwise direction, and the base member and the case. A feeding container comprising a slider that holds a rod-shaped member inside the main body and moves the rod-shaped member along the axis of the case main body to project from the opening according to the rotation of the base member,
Providing at least one dowel on the slider;
The base member is provided with a spiral groove adapted to the dowel to guide the movement of the slider along the axis of the case body,
It is connected to the end of the spiral groove, and the slider is slightly moved along the axis of the case body without the rotation of the base member by the amount of contraction generated during the cooling and solidification process of the fluid that becomes the rod-shaped member. It is a feeding container for a rod-shaped member, characterized in that a longitudinal groove that is linearly moved is formed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The stress caused by the shrinkage that occurs during cooling and solidification of the fluid filled in the case is relieved by the movement of the slider along the longitudinal groove formed at the rearmost end of the spiral groove of the case body.
[0007]
【Example】
Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 to 3 schematically show the cross section and appearance of the configuration and components of a bar-shaped member feeding container according to the present invention.
[0008]
The number 1 in the figure is a hollow case body, and the case body 1 is provided with an opening 1a at the tip thereof, and a pair of long holes 1b are provided at positions facing the peripheral wall.
[0009]
Reference numeral 2 denotes a base member for holding the case main body 1, and 3 denotes a cover for the base member 2. The cover 3 can turn the base member 2 clockwise or counterclockwise separately from the case body 1.
[0010]
Further, 4 is a slider for holding a rod-like member B such as lipstick, 5 is a dowel which is paired on the left and right as shown in the example integrally formed with the slider 4, and 6 is provided on the inner peripheral surface of the base member 2. The dowel 5 of the slider 4 is adapted to fit into the spiral groove 6 through the long hole 1 b of the case body 1.
[0011]
Reference numeral 7 denotes a longitudinal groove connected at the rearmost end of the spiral groove 6, and reference numeral 8 denotes a cap that fits the cover 3 and surrounds the entire case body 1.
[0012]
In the feeding container configured as described above, in order to feed the rod-shaped member B out of the container, first, after removing the cap 8, the annular member 9 is held by one finger, and the cover 3 is attached to the case body 1 by the other finger. Rotate around.
[0013]
Then, the base member 2 rotates integrally with the cover 3, and at this time, the dowel 5 of the base member 2 moves along the spiral groove 6, but the dowel 5 enters the elongated hole 1 b of the case body 1. Therefore, it moves linearly along this long hole 1b, and as shown in FIG. 4, the rod-shaped member b is exposed from the opening 1a according to the amount of movement.
[0014]
In order to manufacture products such as lipstick, when the fluid is filled in the container with the slider 4 closest to the bottom surface of the cover 3, the length direction in the cooling and solidification process depends on the size and material. In this case, there is a difference in the cooling rate between the portion in contact with the case body 1 and the portion in contact with the slider 4, and in particular, in the portion C of FIG. Therefore, nests (cavities formed in the vicinity of the central portion) are likely to occur, and cracks may be generated in some cases. In this case, the product value is impaired, and yield reduction is unavoidable.
[0015]
In the present invention, when such contraction occurs, as shown in FIG. 2, the extra stress that causes cracks is significantly reduced because the slider 4 moves along the longitudinal groove 7 by δt, for example. Will be.
[0016]
Resin can be applied to the feeding container according to the present invention, but it may be made of metal or a combination thereof, and the material is not particularly limited.
[0017]
【The invention's effect】
According to the present invention, it is possible to avoid a quality defect that has conventionally occurred in a feeding container for storing a rod-shaped member such as a lipstick, and the productivity can be remarkably improved.
