Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a dispensing container for storing bar-shaped cosmetics such as lipstick.

"Prior Art" One feature of the stick-shaped cosmetic dispensing container is that its length can be set short.

The mechanism can be easily explained by referring to the common configuration shown in FIGS. 1 and 2 showing the present invention. That is, as shown in the figure, this container is provided with a relay tube 3 and a saucer body 4 that is screwed onto the inner peripheral surface of the relay tube 3, and threads are carved in opposite directions on the outer peripheral surfaces of both. ing. In other words, one side (relay tube 3)
A right-hand thread is carved on one side, and a left-hand thread is carved on the other side (the saucer body 4). Therefore, by rotating the rotary cylinder 2, the relay cylinder 3 is rotated and displaced forward, and the rotation of the relay cylinder 3 causes the saucer body 4 to move forward.
will also be displaced forward. As a result, the saucer body 4
The bar-shaped cosmetic held at the tip can be displaced forward by approximately the sum of the length of the relay tube 3 and the receiving tray body 4.

On the other hand, when moving this bar-shaped cosmetic product backwards, by rotating the rotary cylinder 2 in the opposite direction,
At the same time that the relay tube 3 is housed in the rotary tube 2, the saucer body 4 is also housed in the relay tube 3. Therefore, the space for accommodating the tray body 4 and the relay tube 3 is about half the amount of forward displacement created by both, and the length of the container can be set short.

However, with just such an advancing and retracting mechanism, there is no locking mechanism to maintain the storage position when the bar-shaped cosmetic is stored, so vibrations etc. may be applied to the container, causing the relay tube to rotate naturally. The user then moves the cosmetics bar to dispense the stick-shaped cosmetics.
As a result, the dispensed bar-shaped cosmetic hits the top plate of the cap, causing what is known as a top hit.
It will be damaged.

In order to prevent this situation, a locking mechanism was developed to fix the storage position.
This is proposed in Publication No. 49925. This locking mechanism is provided with a concave-convex fitting portion between the movable cylinder core and a piece raised from the bottom of the container housing the cylinder.

``Problems to be solved by the invention'' Since the locking mechanism described above is provided at the center of the container cylinder, there is a problem in that it is difficult to feel the impact of fitting and unfitting on the skin of the hand.

In view of the above-mentioned problems, the present invention aims to provide a device that allows the user to sensitively feel the lock being disengaged.

"Means for Solving the Problems" In order to achieve the above object, the present invention has the following configuration.

That is, the bar-shaped cosmetic dispensing container according to the present invention is composed of a main body tube 1, a rotary tube 2, a relay tube 3, a saucer body 4, and a cap 5.

The main body tube 1 has a cylindrical shape with a first screwing piece 6 protruding from the inner circumferential surface of the base end.

The rotary tube 2 has a bottomed cylindrical shape and is attached to the base end of the main body tube 1 so as to be mutually rotatable and cannot be removed.

The relay tube 3 has a flange piece 7 around its base end that closely slides on the inner circumferential surface of the rotary tube 2, and a first thread 8 on the outer circumferential surface into which the first screw piece 6 is screwed. It has a cylindrical shape and is engraved with a second screwing piece 9 protruding from the inner peripheral surface of the tip, and is assembled into the rotary cylinder 2 so as to be able to move forward and backward, but not to rotate relative to each other.

The saucer body 4 has a tip of a threaded rod 11 which is threaded with the second threaded piece 9 and has a second thread 10 carved in the outer peripheral surface, which is a reverse thread from the first thread 8. A retaining plate 13 whose outer circumferential surface is slidable in close contact with the inner circumferential surface of the main body cylinder 1 is integrally provided.

The cap 5 has a capped cylinder shape that is fitted into the tip of the main body cylinder 1.

A feature of the present invention is that a locking protrusion 12 is provided on the base end of the inner circumferential surface of the rotary cylinder 2, which the flange piece 7 of the relay cylinder 3 rides over and locks just before the screwing limit. .

"Operation" The operation of the present invention will be explained below with reference to the drawings.

In the above configuration, when the bar-shaped cosmetic is exposed (see Fig. 1), when the main body tube 1 is held and the rotary tube 2 is rotated, it becomes possible to move forward and backward with the rotary tube 2, but not to rotate with respect to the rotary tube 2. Assembled relay tube 3
rotates together with the rotary cylinder 2. Due to this rotation, the first threaded piece 6 of the main body cylinder 1 and the first thread 8 of the relay cylinder 3 are screwed together, so that the relay cylinder 3 retreats into the rotary cylinder 2.

On the other hand, the tray body 4 is assembled to the main body cylinder 1 so that it can move forward and backward, but cannot rotate with respect to the main body cylinder 1. The coupling piece 9 is screwed together, and since the second thread 10 is set in the opposite direction to the thread of the first thread 8, it retreats into the relay cylinder 3.

When the rotation of the rotating cylinder 2 continues and the relay cylinder 3 reaches near the screwing limit position with the rotating cylinder 2, the flange piece 7 of the relay cylinder 3 protrudes from the base end of the inner circumferential surface of the rotating cylinder 2. It abuts against the locking protrusion 12. When the rotary cylinder 2 is further rotated from this state, the flange piece 7 climbs over this locking protrusion 12 and reaches the screwing limit position.

In this state, the bar-shaped cosmetic is therefore housed in the main body tube 1, and the cap 5 is placed here (see FIG. 2).

The bar-shaped cosmetic is maintained in the above state, but at this time, even if vibration etc. are applied to the container and a force is applied to the relay tube 7 in the counter-rotation direction,
Since the flange piece 7 abuts against the locking protrusion 12 and prevents rotation in the counter-rotation direction, the rotating cylinder 2
will not rotate any further.

Therefore, the bar-shaped cosmetic does not move forward and collide with the top wall of the cap 5, unlike the conventional case, and is not damaged.

In addition, the above-mentioned locking mechanism has a rotary cylinder 2 that comes in contact with the hand.
Because it is directly behind the flange piece 7, the locking protrusion 12
Since the state in which the relay tube 3 is overcome can be sensitively felt with the hand, it can be determined that the relay tube 3 has reached the set screwing position. Therefore, the rotating tube 2 is not rotated more than necessary and the threads are not damaged, and the user is provided with a comfortable feeling of use.

To expose the bar-shaped cosmetic from the above state,
After removing the cap 5, the rotary cylinder 2 may be rotated in the opposite direction. As a result, the flange piece 7 first climbs over the locking protrusion 12, and furthermore, the bar-shaped cosmetic is exposed by an action opposite to the action at the time of storage described above.

"Example" An example of the present invention will be described with reference to the drawings. FIG. 1 shows a state in which the tray body 4 and the relay tube 3 are moved forward to expose the cosmetic bar, and FIG. 2 is a diagram showing a state in which the tray body 4 and the relay tube 3 are moved backward to accommodate the cosmetic bar.

A locking protrusion 12 is provided around the base end of the inner circumferential surface of the rotary cylinder 2, and its height is such that the flange piece 7 can get over it without much resistance, and that the flange piece 7 that has climbed over it will not be affected by vibrations or the like. Holding protrusion 12
has been set to such an extent that it cannot be overcome naturally. When set to this state, a light snapping sound will be emitted when the vehicle crosses over.

A plurality of guide strips 14 are provided on the inner circumferential surface of the rotating cylinder 2, and a guide groove 15 with which the guide strips 14 engage is provided.
is formed on the flange piece 7, whereby the relay cylinder 3 is assembled to the rotary cylinder 2 so that it can move forward and backward, but cannot rotate relative to each other.

An undercut groove 16 is formed at the tip of the inner peripheral surface of the rotary cylinder 2, and an undercut strip 17 that fits into the undercut groove 16 is provided around the base end of the outer peripheral surface of the main body cylinder 1. The assembly of the main body cylinder 1 is made mutually rotatable and impossible to remove.

The forward movement of the relay cylinder 3 is regulated by the flange piece 7 coming into contact with the base end of the main body cylinder 1 which is fitted and assembled into the rotary cylinder 2. Also, as a result, the relay tube 3 is assembled into the rotary tube 2 so that it cannot be removed from the rotary tube 2.

A plurality of vertical stripes 18 are provided on the inner circumferential surface of the main body cylinder 1, and vertical grooves 19 that engage with the vertical stripes 18 are formed in the saucer body holding plate 13. Thereby, the main body cylinder 1 and the saucer body 4 are assembled so that they can move forward and backward, but cannot rotate relative to each other.

A protrusion 20 is formed at the base end of the saucer body 4, and when this protrusion 20 comes into contact with the second screwing piece 9, the relay tube 3 of the saucer body 4 is tightened during use.
This prevents it from slipping out.

"Effects of the Invention" As described above, the present invention provides the locking protrusion 12 on the base end of the inner circumferential surface of the rotary cylinder 2.
Since the bar-shaped cosmetic product is prevented from rotating naturally, there is no possibility that the bar-shaped cosmetic product will be accidentally exposed and hit the top wall of the cap 5, causing damage.

In addition, the set screwing position can be known by being able to feel the flange piece 7 passing over the locking protrusion 12 from directly behind the container wall that is being touched by the hand. This eliminates the possibility of damaging the threads, threaded pieces, etc. by rotating the rotary cylinder 2, and provides excellent effects such as improved usability.
