Description

[Detailed description of the invention] The present invention relates to a container for dispensing bar-shaped cosmetics, and is provided so that the bar-shaped cosmetics can be easily replaced.

Various types of containers for dispensing bar-shaped cosmetics have been known in the past, but it is difficult to replace them with a new cosmetic bar after the bar-shaped cosmetic is used up. Instead, I often had to throw away the containers and buy new ones.

The present invention is designed to eliminate the above-mentioned drawbacks and to be convenient in use.The drawings will be explained below. 1 is the main cylinder. The main cylinder has a lower end cylinder part as a grip cylinder part 2, and a cylinder part above the grip cylinder part as a cylinder part 3 for threaded fitting, which will be described later. A groove 4 is opened in the upper end surface of the cylindrical portion and vertically provided in the vertical direction. The dividing groove continues horizontally from the top of the vertical part 4a to a horizontal part 4b having approximately the same width as the vertical part, and the inner surface of the vertical part has the width of the vertical part and the width of the vertical part. A large horizontal width groove portion 4c is formed which is wider than the vertical width of the installed portion. Also, the lower end of the split groove,
From slightly above the lower end, second and third horizontal portions 4 are installed in a horizontal direction opposite to the side where the horizontal portion 4b is provided.
d and 4e are preferably bored continuously with the split grooves, and a large vertical width groove 4f having the same width as the large width groove 4c is preferably provided on the inner surface of the third horizontal portion.

The screw tube 5 is rotatably fitted into the outer surface of the screw tube fitting tube portion described above. The screw tube has two vertically parallel screw grooves 6 and 7 on its inner surface, and these two screw grooves are provided with a phase difference of 180 degrees. Of the two screw grooves, the lower screw groove 7 has approximately the same width as the split groove, and the upper screw groove is narrower than the lower screw groove. The direction in which the spiral groove ascends is opposite to the direction in which the horizontal part is bored, as shown in the figure, so that the horizontal part 4b is bored to the left with the vertical part as the base end when viewed from the side. If it is, the spiral groove will spiral upward in the upper right direction. In this specification, the right direction is defined as a forward direction, and the left direction is defined as a reverse direction.

A support cylinder 10 having first engaging elements 9 protruding from the outer surface of the first circumferential wall 8 is fitted into the main cylinder described above.
The first engager passes through the grooves 4, 4 and engages the end of the engager with the threaded groove 7 below.It has a threaded cylinder 5 and can rotate the knob cylinder part 2 in both forward and reverse directions. The first engaging element is pushed by the side edge of the split groove and moved up and down with respect to the main cylinder 1 by advancing inside the screw groove.

The lower part is removably fitted into the support cylinder 10, and the lower part of the second peripheral wall of the rod-shaped cosmetic fitting cylinder 11 is fitted into the main cylinder 1. The fitting cylinder has an upper part of its second peripheral wall having approximately the same outer diameter as the supporting cylinder,
Second engaging members 12, 12 are made to protrude from the upper outer surface. The second engaging element has a base portion as a large diameter portion 12a, the large diameter portion is placed in the large width groove portion 4c, and a tip portion as a small outer diameter portion 12b, and the small outer diameter portion is passed through the split groove 4. The tip of the small outer diameter portion is engaged in the upper spiral groove 6.

In the above configuration, when holding the screw tube and turning the knob tube portion 2 in the forward direction, that is, in the upward direction of the screw groove, the small outer diameter portion of the fitting tube 11 is pushed by the side edge of the groove, similar to the support tube described above. , and the tip of the small outer diameter portion is pushed up inside the upper spiral groove, so that it rises inside the main cylinder while being fitted in the support cylinder. Fitting cylinder second engaging element 12,1
Even when 2 reaches the entrance of the horizontal part 4b, its large diameter part 12a is within the large width groove part 4c, and the large width groove part is not provided on the inner surface of the horizontal part. Since the diameter portion has a larger diameter than the horizontal portion, it passes through the entrance of the horizontal portion and ascends. Next, support tube 1
The first engagers 9, 9 of 0 reach the entrance of the horizontal part,
Since the horizontal part has almost the same width as the vertical part, the first engager enters into the horizontal part, so that it cannot move up against the main cylinder or screw against the screw cylinder. Both will be suspended. On the other hand, the fitting cylinder 11
continues to rise, so the fitting cylinder 10
As shown in FIG. 3B, the fitting cylinder can be removed because it protrudes upward from the main cylinder. After the removal, insert the fitting tube into which the new bar-shaped cosmetic is fitted into the support tube as shown in FIG.
2 and 12 are pushed down inside the vertically installed part, and the first engaging element is pushed out from the horizontally installed part 4b and enters the vertically installed part 4a, and at this time, the fitting between the support cylinder and the fitting cylinder is completed, Furthermore, by turning the knob cylinder part in the opposite direction,
The support tube and the fitting tube move down inside the main tube, and the bar-shaped cosmetic is fed into the main tube. After the upper cylinders have descended to the lower limit, their first and second engagers 9 and 12 are pushed into the second and third horizontal parts 4d and 4e, causing the knob cylinders to rotate in the opposite direction. will be stopped.

The present invention has the above-mentioned structure, and the bar-shaped cosmetic support member is formed by fitting two members vertically, instead of one member as in the conventional case, and the upper fitting tube into which the bar-shaped cosmetic is fitted is formed. Since it is detachable from the lower support tube, it is easy to replace the rod-shaped cosmetics.Two screw threads are provided on the inner surface of the screw tube, which are vertically parallel to each other. Since the second engaging element 12 of the upper fitting tube is engaged in the screw groove, and the second engaging element 12 of the upper fitting cylinder is engaged in the upper screw groove, after the first engaging element enters the horizontal part 4b and the support cylinder stops rising. Also, it is easy to continue to raise the second engaging element and pull up the fitting cylinder from the support cylinder, and the split groove 4
is a vertically installed portion 4a which is opened and bored in the upper end surface of the main cylinder.
A large width groove portion 4c is provided on the inner surface, and a horizontal portion 4b having a vertical width that is approximately the same as the vertical portion is continuous from the top of the vertical portion in the horizontal and lateral directions, and the base of the second engaging element 12 is , the second engager tip is positioned in the large width groove portion as a large diameter portion having a diameter larger than the vertical width of the horizontal portion 4b, and the second engager tip portion is inserted through the vertical portion as a small diameter portion. Since the first engaging element passed through the vertical part and engaged its tip with the lower spiral groove 7, the first and second engaging elements were connected to the upper and lower parts of the same split groove. Even though the first engaging element is inserted into the horizontal part, only the first engaging element can be guided into the horizontal part, and the second engaging element can be prevented from entering the horizontal part. There is no need to insert the engaging element into a separate groove, and the number of grooves in the main cylinder can be reduced, and the strength of the cylinder for fitting the main cylinder is not impaired as would be the case if the number of grooves was increased. do not have.
