Description

[Detailed Description of the Invention] The present invention relates to a dispensing container for bar-shaped solid cosmetics such as eyebrows and eye shadows.

In recent years, as a dispensing container for this type of bar-shaped solid cosmetics,
A cartridge container in which a bar-shaped solid cosmetic such as Mayuzumi is removably housed is removably attached to the tip of the dispensing container body, and when in use, the bar-shaped solid cosmetic in the cartridge container is inserted into the dispensing container main body. When the bar-shaped solid cosmetic in the cartridge container of the parenthesis is used up after being pushed out with the sliding shaft provided in the bracket, it is replaced with a new cartridge container. A dispensing container for cosmetics has been developed.

By the way, in the cartridge container, one end of the bar-shaped solid cosmetic is held, and when the cartridge container is attached to the dispensing container main body, it is removably connected to the tip of the sliding shaft on the dispensing container main body side. A holder is provided, and conventionally, the holder and the sliding shaft have generally been connected by a screw connection or a tight fit connection in which one is press-fitted into the other.

However, since the former method uses a screw connection, there is an inconvenience in that the cartridge container must be rotated at the same time when it is fed out and attached (set) to the container body, and in the latter method, the connection part is only slightly connected. However, it has the disadvantage that its functionality deteriorates significantly when it wears out.

The present invention has been developed in view of the above circumstances, and its purpose is to make it easy to attach and detach the cartridge container to the dispensing container body, and to make it possible to easily attach and detach the cartridge container to the dispensing container body, and to remove the sliding shaft from the cartridge container. To provide a container for dispensing bar-shaped solid cosmetics, which allows a holder and a sliding shaft to be easily and reliably engaged and disengaged simply by reciprocating, and whose function is not deteriorated.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an overall view of a dispensing container according to the present invention, in which reference numeral 1 denotes a dispensing container main body, and numeral 2 denotes a cartridge container attached to the tip of the dispensing container main body 1.

The outer shape of the dispensing container main body 1 is formed by an outer cylinder 3 whose base end (right side in the illustrated example) is closed and whose distal end is open, and a connecting cylinder 4 rotatably attached to the outer cylinder 3. has been done.

Further, a let 17 is fixedly provided on the inner periphery of the distal end of the outer cylinder 3, and the let 17 is fixedly provided on the inner periphery of the proximal end of the connecting cylinder 4.
A let 16 that is rotatably fitted in the circumferential direction is fixedly provided.

Furthermore, a helical tube 6 having a helical groove 8 on the peripheral wall is fixedly attached to the inner periphery of the let 17 of the outer tube 3, and a helical groove 8 of the helical tube 6 is attached to the inner periphery of the helical tube 6. A guide tube 7 having a common helical groove 8 is fixedly provided to the helical tube 6.

On the other hand, inside the guide tube 7, polyoxymethylene (P
OM) A sliding shaft 5 made of resin or the like is provided so as to be movable in the axial direction with a protrusion 5a provided at the base end of its outer periphery fitted into a spiral groove 8 of a spiral tube 6 and a guide tube 7. It is being

By rotating the outer cylinder 3 in one direction (clockwise) with respect to the connecting cylinder 4, the sliding shaft 5 slides in the direction in which it projects, that is, to the left in the figure, and in the other direction (counterclockwise). By rotating it, it slides in the sinking direction, that is, to the right in the figure.

Further, at the tip of the sliding shaft 5, there is a vertical groove 9 that divides the tip into two in the axial direction, and two opposing retaining pieces 10, 10 are formed on both sides of the vertical groove 9, respectively. At the same time, protrusions 10a, 10a are formed on the outer periphery of the tips of these engaging pieces 10.10, respectively.

There are guide holes 11 on the outside of these retaining pieces 10°10.
A sliding ring 11 having a diameter is fitted.

The engagement pieces 10.10 are formed in advance so that their tips are spaced apart from each other as shown in FIG. They can be compressed as shown in Figure 1, or separated as shown in Figure 2.

On the other hand, a holder 12 that is slidable in the axial direction is fitted into the cartridge container 2 that is attached to the tip of the dispensing container main body 1.
One end of a bar-shaped solid cosmetic 13 such as Mayuzumi is press-fitted into a holder hole 12a formed on one end side.

Also, the wall surface 1 on the opposite side of the holder hole 12a of this holder 12
2e, a plurality of locking pieces 12b, which are engaged with the engaging pieces 10, 10 of the sliding shaft 5, are protruded to form a cylindrical shape, and the outer periphery of the tip of each of these locking pieces 12b has protrusion 1
2c, and a stepped portion 12d is formed on the inner peripheral portion of the tip.

Further, a circumferential groove 1 is provided on the inner periphery of the base end of the cartridge container 2.
4 are formed, and the protrusions 12c are fitted into the circumferential grooves 14, respectively.

The reference numeral 15 indicates a leaf spring, 1B, 19.20 a gasket, 21.22 a washer, and 23.24 a spring.

The operation of the dispensing container for bar-shaped solid cosmetics according to the present invention constructed in this way will be explained below.

As shown in FIG. 1, when the outer cylinder 3 is rotated clockwise with the cartridge container 2 attached to the dispensing container main body 1, the spiral groove 8 rotates clockwise and pushes the protrusion 5a of the sliding shaft 5, causing the sliding The moving shaft 5 is slid in the direction of the tip (leftward in the figure).

When this sliding shaft 5 slides, the sliding ring 1
1 also follows (follows due to the close contact effect with the sliding ring 11 due to the separating action of the retaining piece 10.10), but this sliding ring 11 is prevented from following by the proximal end surface 2a of the cartridge container 2 on the way. As a result, only the sliding shaft 5 slides from the middle.

Here, when the sliding shaft 5 is further slid in the same direction, the tip of the sliding shaft 5 comes into contact with the wall surface 12e of the holder 12,
Slide the holder 12 to the left in the figure.

When the holder 12 is slid to the left, each locking piece 12b
The protrusions 12c are removed from the circumferential groove 14, and as a result, each locking piece 12b is inserted into the cartridge container 2 via each protrusion 12c.
is pressed by the inner peripheral surface of the

At this time, the pair of retaining pieces 10, 10 of the sliding shaft 5 are released from being restrained by the sliding ring 11, and as a result, the engaging pieces 10, 10 are moved one inch in the direction in which their tips are separated. The convex portions 10a, 1 of the engaging pieces 10, 10 spread out in a shape
0a is pressed against the inner surface of each locking piece 12b, and as a result, the sliding shaft 5 and the holder 12 are connected (engaged) (fourth
(see figure).

In addition, these connections are made especially by a retaining piece 10 which is divided into two parts by the vertical groove 9 and elastically deformed in the direction of separating from each other.
This is done by engagement with the locking piece 12b which is pressed against the inner peripheral surface of the cartridge container 2 through the protrusion 12c and narrowed inward, so that the locking piece 10 and the locking piece 12b are mutually They act in the direction of engagement, and as a result, these engagement forces become stronger, and the sliding shaft 5 and holder 12 are reliably connected.

Then, by further sliding the sliding shaft 5 in this state, the bar-shaped solid cosmetic 13 is projected from the tip opening 2b of the cartridge container 2.

On the other hand, when the outer cylinder 3 is rotated to the left in the state shown in FIG. 4, the spiral groove 8 rotates to the left and pushes the protrusion 5a of the sliding shaft 5 toward the proximal end, causing the sliding shaft 5 to move to the right in the figure. be made to slide.

When the sliding shaft 5 slides to the right, the holder 12 also slides to the right.

At this time, the sliding shaft 5 and the holder 12 are separated by a pair of retaining pieces 10 that act in a direction to separate them outward.
Since the holder 12 is reliably connected by the engagement action of the locking piece 12b which is narrowed inward, there is no risk that the holder 12 will be separated from the sliding shaft 5 midway when the holder 12 is returned.

When each protrusion 12c of each locking piece 12b is fitted into the circumferential groove 14 as shown in FIG.
The engagement action of b on the engagement pieces 10, 10 is released, and at this time, the bodies of the engagement pieces 10, 10 enter into the sliding ring 11 and are pressed in the direction of approaching each other, thereby causing the engagement. The engagement of the pieces 10, 10 with each locking piece 12b is released, and as a result, the connection between the sliding shaft 5 and the holder 12 is released.

Therefore, when separating the sliding shaft 5 and the holder 12, the protrusion 12c fits into the circumferential groove 14, the locking piece 12b of the holder 12 opens outward, and the sliding shaft 5 is engaged. Piece 10
Since the outer cylinder 3 is narrowed inward by the sliding ring 11, the resistance force against the rotation of the outer cylinder 3 does not increase, and the operation can be performed smoothly.

Furthermore, when focusing on the state when the engagement piece 10 of the sliding shaft 5 is separated from the holder 12, the engagement piece 10 is
Since the locking piece 12b of the holder 12 is narrowed by the sliding ring 11 and is open, the convex portion 10a of the engaging piece 10 and the stepped portion 12d of the locking piece 12b can be separated with slight contact. These convex portions 10a and stepped portions 12d
There is almost no wear and tear, allowing it to perform its functions for a long period of time.

Even if some wear occurs on these, in the present invention, the pair of engaging pieces 10 are divided into two parts by the vertical groove 9 and are molded in the direction of moving outward, and the protrusions 12c allow the engagement pieces 10 to move inwardly. Since the holder 12 and the sliding shaft 5 are connected by the engagement with the narrowed locking piece 12b, there is no risk that the connection function will deteriorate.

In other words, in the present invention, the engaging piece 10 is divided into two parts by the longitudinal groove 9, and is molded in a direction that separates them outwards, so that the coupling effect between the sliding shaft 5 and the holder 12 is strengthened, and the retaining piece By allowing the inward elastic deformation of the retaining piece 10, the retaining piece 10 can be smoothly separated, and furthermore, wear of the convex portion 10a can be prevented.

In addition, when replacing the cartridge container with another new cartridge container, remove the cartridge container 2 in the state shown in FIG. Simply pull it out from the main body 1 and then insert a new cartridge container.

As described in detail above, in the dispensing container for bar-shaped solid cosmetics according to the present invention, the cartridge container is attached to the dispensing container body, and the sliding shaft and the holder are engaged and disengaged by simply reciprocating the sliding shaft during use. This makes it extremely easy to attach and detach the cartridge container to the main body of the dispensing container, and the engaging piece of the sliding shaft is divided into vertical grooves at the tip of the sliding shaft. , and the engaging pieces are molded so that they are spaced apart from each other, so that the retaining piece and the locking piece of the holder interact with each other in a direction that strengthens their engagement, and the holder slides Not only is it more securely connected to the shaft, but since the engaging piece can be elastically deformed inward, its functionality will hardly deteriorate even if some wear occurs due to excessive use. It has excellent practical effects such as:
