Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder case refill attachment / detachment mechanism, and more particularly to a powder case refill attachment / detachment mechanism which enables a powder product refill to be easily attached and detached without using an adhesive.

[0002]

2. Description of the Related Art Generally, there is no powder product in which a refill is made detachable, and only an example is found in a compact container or the like.

[0003]

The conventional refill attachment / detachment mechanism has a structure in which a middle plate of a hard material can be exchanged into a container body of a hard material as seen in a general compact container. There has been a problem that it is difficult to apply the constitution as it is to a soft refill made of a polypropylene material like a refill of a powder product.

Further, the conventional refill attachment / detachment mechanism has a large number of parts, and the refill is temporarily fixed with an adhesive or the like. Therefore, the overall mechanism is complicated and the manufacturing cost is relatively high. was there. An object of the present invention is to provide a powder case refill attachment / detachment mechanism which solves the above problems.

[0005]

According to the present invention, a rib is protruded from the inner wall of the case body, and the dimension between the lower end of the rib and the inner bottom surface of the case body is substantially equal to the height of the refill. A flange is formed at the upper end of a refill formed of a flexible material, the outer dimension of the flange is larger than the inner diameter of the rib, and a puff is formed above the rib in the case body. This is a powder case refill attachment / detachment mechanism that secures a storage space for the powder case.

[0006]

The refill attachment / detachment mechanism for a powder case according to the present invention presses and fits the refill from the upper end opening of the case body when the refill is attached. At this time, the refill flange is bent because of its flexibility. As a result, it is set stably at a predetermined position beyond the rib.
Then, when removing the refill, put your finger on the inner wall of the refill and press it against the inner wall of the case and pull it up to curve the flange and pull it out of the case,
Alternatively, make a hole in the bottom of the case body and push the refill up by pushing a finger or a pusher from there, or pull up the knob provided on the flange part of the refill and pull out the refill from the powder case .

In this manner, the knob provided on the flange is pulled up to pull out the refill from the powder case,
Alternatively, a hole is formed in the bottom surface of the case body, and a finger is pushed from there to push the refill up.
In this way, the refill can be reliably attached and detached by a simple operation, and thus the refill can be replaced.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view of a refill attaching / detaching mechanism according to a first embodiment of the present invention.
A case lid 2 is attached so as to be able to be crowned, and a rib 4 is protruded from an inner side wall 3 of the case body 1.

The ribs 4 are for stably holding the refill 5 and may be provided separately at several locations or may be provided over the entire circumference. Dimension L1 between lower end of rib 4 and inner bottom surface of case body 1
Are formed to have substantially the same size as the height L2 of the refill 5.

A flange 6 is provided at the upper end of the refill 5.
Are formed, and an outer dimension L3 of the flange portion 6 is formed.
Are formed to be larger than the inner diameter L4 of the rib 4. As a result, when the refill 5 gets over the ribs 4, the refill is set in the case body without rattling.

[0011] Between the case body 1 and the case lid 2,
Since the storage space 8 for the puff 7 is ensured, it is very convenient when using powder.

In the first embodiment shown in FIG. 1, a tongue-shaped knob 6a is formed protrudingly at a part of the flange 6 of the refill 5, and the knob 6 is used when the refill 5 is taken out. Is what is done. The knob 6 is desirably provided with a cut or a hole 6b so that a finger does not slip during removal.

In the second embodiment shown in FIG. 2, a hole 9 through which a finger or the like can pass is formed in the bottom surface of the case body 1, and the refill 5 is pushed out from the hole 9 to take out the refill. Becomes In the case of the second embodiment, the knob 6 of the refill 5 becomes unnecessary. In addition, the code | symbol 10 in a figure is a powder,
Reference numeral 11 denotes a net body for holding the powder.

Next, the refill 5 has a filling hole 12 on the bottom surface, and a lid seal 13 is stretched on the upper opening.
After the powder is injected from the filling hole 12, the filling hole is sealed with a bottom seal 14.

When the refill 5 having the above structure is mounted on the case body 1 of the present invention, first, the refill is pushed into the main body from above, and the flange portion 6 of the refill is curved,
It is stored in a predetermined position over the rib 4. Then, the lid seal 13 of the refill is pulled apart. When the refill is stored in the case main body, the refill has a configuration in which the upper surface of the flange portion is pressed by the ribs 4, so that the refill does not accidentally pop out of the case main body.

When taking out the refill, the refill is pulled out from the hole 9 with a finger or the like, the inner wall of the refill is pushed up, or the knob is used to pull out the refill upward, and the flange portion of the refill is bent. It must be removed from the case body after climbing over the ribs again.

[0017]

[Effects of the Invention] Therefore, the present invention has an excellent effect that the refill of a powder product can be easily attached and detached without using an adhesive, and the overall mechanism is simple, so that the manufacturing cost is reduced. There is.
