Description

[0001]
[Industrial application fields]
The present invention relates to a powder container in which a powder-filled refill container is detachably attached to the container body, which facilitates the attachment / detachment of the refill container and further prevents the refill container from rotating within the container body. It is.
[0002]
[Prior art]
From the viewpoint of effective use of resources, it is desirable to have a refill structure that refills only the contents in a compact container or powder container. Conventionally, for example, a refill container is adhered to the bottom surface of the main body container with an adhesive or the like, or a rib is projected from the inner wall of the powder container, and a flange portion is formed at the upper end of the refill container. In some cases, the outer dimension of the portion is formed larger than the inner diameter dimension of the rib.
[0003]
[Problems to be solved by the invention]
However, in the conventional powder container described above, when an adhesive is used, a force is required for removal. In addition, when a flange is formed on the entire circumference of the refill container, it is necessary to bend over the entire circumference of the flange when locking or separating the refill container on the powder container. However, there is a problem that the refill container cannot be attached and detached.
[0004]
In particular, in the conventional example in which flanges are provided on the entire circumference of the refill container, there is a possibility that the refill container rotates in the powder container and it is difficult to apply the powder to the puff.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, a powder container according to the present invention is formed in a substantially cup shape and provided with a rib on the inner periphery of the opening, and is formed in a substantially cup shape so that it can be inserted into the container body. The refill container can be locked to the container body by providing a plurality of projecting pieces on the outer periphery of the opening of the refill container and positioning the refill container on the lower side of the rib. The rib is provided with a notch, and a gripping protrusion formed on the outer periphery of the opening of the refill container is longer than the protrusion and substantially equal in width to the notch. When the refill container is locked to the powder container, the gripping projecting piece can be inserted into the notch.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the position of the powder container according to the present invention will be described with reference to the drawings. 1 is an overall perspective view of the powder container, FIG. 2 is a diagram for explaining the operation when the refill container is attached to and detached from the powder container, FIG. 3 is a top view, FIG. 4 is a side sectional view, and FIG. It is.
[0007]
The container main body 1 shown in FIG. 1 is formed in a substantially cup shape, and is composed of a substantially circular main body bottom surface 1a and a main body side wall 1b. An opening 1c is formed at the upper end of the main body side wall 1b. A step 1d for fitting a lid (not shown) is formed on the outer peripheral surface of the opening 1c, and a rib 2 projecting inward is provided on the inner peripheral surface.
[0008]
The rib upper surface 2 b of the rib 2 is formed as an inclined surface inclined downward, and the rib lower surface 2 c is formed as an inclined surface slightly inclined upward in the end direction of the rib 2. Moreover, the notch part 2a is provided in two places which the rib 2 opposes. These notches 2a are formed so as to be inclined surfaces whose intervals increase upward.
[0009]
The refill container 3 is formed in a substantially cup shape like the container body 1, and is composed of a bottom surface 3a and a side wall 3b, and a flange 3c is formed on the outer periphery of the upper end of the side wall 3b. A seal 4 is attached to the upper surface of the refill container 3, and the refill container 3 filled with powder is sealed inside.
[0010]
The outer diameter of the side wall 3b and the flange 3c of the refill container 3 is formed smaller than the inner diameter of the rib 2, and the height from the bottom surface 3a to the flange 3c is formed lower than the height from the main body bottom surface 1a to the rib lower surface 2c. ing.
[0011]
At the edge of the flange 3c, four protrusions 3d are formed at intervals of 90 degrees so as to extend outward in the diameter direction. The distance between the tips of the projecting pieces 3d and 3d facing each other is set substantially equal to the inner diameter of the main body side wall 1b.
[0012]
Furthermore, a gripping protrusion 3e that is longer than the protrusion 3d is formed on the flange 3c. The width of the gripping protrusion 3e is formed substantially equal to the width of the notch 2a of the container body 1.
[0013]
The operation of attaching and detaching the container body 1 and the refill container 3 configured as described above will be described. First, when the refill container 3 is pushed into the container body 1 (in the direction of arrow X in FIG. 2A), the projecting piece 3d of the flange 3c comes into contact with the rib upper surface 2b of the rib 2 and bends along the rib. Further, by pushing the refill container 3 into the container body 1, the flange 3c enters the inside of the rib 2, and the refill container 3 is locked in the powder container as shown in FIG. 2 (b).
[0014]
At this time, the projecting piece 3d is not formed over the entire circumference of the flange 3c, but is provided in a partly divided manner, so that the projecting piece 3d bends independently and does not require a large force. .
[0015]
Further, since the rib upper surface 2b is inclined downward, it becomes a guide for the projecting piece 3d, and the projecting piece 3d can be easily bent and pushed into the container body 1. In this state, each projecting piece 3d sinks to the lower side of the rib 2, and the refill container 3 does not fall off even if the powder container 2 is tilted. Further, since the rib lower surface 2c is slightly inclined upward, the projecting piece 3d bends downward even when the refill container 3 is pulled up and removed, so that it can be removed smoothly.
[0016]
As shown in FIG. 3, when the refill container 3 is locked to the container main body 1, the gripping protrusion 3 e of the refill container 3 is locked to the notch 2 a of the rib 2 in alignment. Then, since the length of the gripping protrusion 3e is formed longer than that of the protrusion 3d, the gripping protrusion 3e is bent and an end portion is disposed in the notch 2a.
[0017]
At this time, the width of the gripping protrusion 3e is formed to be substantially equal to the width of the notch 2a, so that the gripping protrusion 3e is inserted into the notch 2a and the right and left movement is restricted, and accordingly, the refill container 3 Can be prevented from rotating in the container body 1.
[0018]
The refill container 3 thus locked to the container body 1 is used with a net 6 placed after the seal 4 is peeled off as shown in FIG. Further, the inner lid 8 is fitted into the opening 1c, the puff 9 is placed, and the lid body 7 is fitted into the step portion 1d.
[0019]
Further, as shown in an enlarged view in FIG. 5, the upper end of the gripping protrusion 3e is separated from the notch 2a because the notch 2a is formed on an inclined surface whose diameter increases upward. It becomes. Therefore, the end of the gripping protrusion 3e is raised and easily gripped, and can be easily pulled up (in the direction of arrow Y in FIG. 2 (c)).
[0020]
Then, as shown in FIG. 2 (c), the projecting piece 3d abuts on the rib lower surface 2c and bends, the engagement between the projecting piece 3d and the rib 2 is released, and the refill container 3 can be separated from the container body 1. it can. Thereafter, a new refill container 3 prepared separately is locked to the container main body 1 so that the container main body 1 can be used continuously.
[0021]
In the above embodiment, the protruding pieces 3 are provided at four positions at intervals of 90 degrees. However, the present invention is not limited to this, and the position and number of positions where the refill container 3 can be locked in the container body 1. Other configurations can be taken, for example, providing three locations at intervals of 120 degrees. For example, it may be provided in three directions or more in the vicinity of the gripping protrusion 3e.
[0022]
【The invention's effect】
As explained in detail above, the powder container according to the present invention is provided with a plurality of projecting pieces on the flange of the refill container so that it can be partially locked to the powder container. This can be done easily by reducing.
[0023]
In addition, by inserting the gripping protruding piece for taking out into the notch portion of the main body rib, it is possible to ensure easy attachment and detachment and to prevent the refill container from rotating in the container main body. Therefore, handling can be facilitated during use.
