ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a netted refillable container for containing a powdery cosmetic material and, more particularly, a netted refillable container for preventing solidification of the contained powdery cosmetic material, and also for preventing spillage of the powdery cosmetic material when not in use.
2. Description of Prior Art
Powdery cosmetic materials, e.g., foundations, white powder, or the like are typically contained in a dish-shaped refillable container having an opening formed at the top of the refillable container covered with a netting. This refillable container serves as a cosmetic compact case with an outer container attached with an openable lid. The netting prevents the contained powdery cosmetic material from scattering, and also helps provide the suitable amount of powdery cosmetic material when a cosmetic tool, e.g., powder puff is rubbed against the meshes of the netting.
In respect of the refillable container, since the powdery container material is pressed toward the bottom surface by a net or a cosmetic tool whenever in use, the powdery container material gradually solidifies and becomes difficult for the powdery container material to stick suitably as well as uniformly to a cosmetic tool, e.g., powder puff when in use. Therefore raising a problem in which the disposal of the refillable container and the powdery cosmetic material becomes unavoidable even if there still is powdery cosmetic material remaining inside the refillable container.
To solve the above problem, a refillable container has been proposed in which the container body of the refillable container of a flexible synthetic resin material is molded with a projection either on the outer surface of the bottom panel of the container body or on the inner surface of the bottom panel of the outer container containing the container body. With the thus structured refillable container, when the container body is moved toward the bottom panel of the outer container due to force created when a cosmetic tool is pressed against the netting provided at the upper portion of the container body, one of the provided projections makes contact to the opposing surface and restricts movement of the container body, thereby deforming the container body and the side panel of the container body which correspond to the periphery of the projections. According to the above deformation, the contained powdery cosmetic material is fluidized which helps prevent the solidification of the powdery cosmetic material and also enables the refillable container to be thoroughly used without much waste.
With such a conventional refillable container, the container body deforms either where the projection provided on the bottom panel of the container body of the refillable container makes contact to the bottom panel of the outer container or where the projection provided on the outer container makes contact to the bottom panel of the container body. That is, in respect of the bottom panel of the container body, the portion corresponding to the projection maintains flatness, while the bottom panel surrounding the projection deforms. Therefore, the contained powdery cosmetic material is fluidized mainly by the deformation of the side panel rather than the entire deformation of bottom panel of the container body. Nevertheless, to make the container body effectively increase the fluidization of the contained powdery cosmetic material, it is preferable to widen the area of deformation in respect of the bottom panel.
Te refillable container thus structured is shown in FIG.
15
. This refillable container
51
is used in a state in which the refillable container
51
is contained inside a cosmetic compact case
54
having a lid
54
a
and a housing
54
b
. This refillable container
51
is comprised of a container body
52
for containing a powdery cosmetic material
55
and a net frame
53
made up of an engagement loop
53
a
covered by a sheet-like netting
53
b
. The container body
52
is a shallow dish-shaped container molded from a flexible synthetic resin, and has a gentle tapered peripheral sidewall
52
b
in between a bottom portion
52
a
and an opening rim
52
c.
The engagement loop
53
a
of the net frame
53
is an annular body having the diameter substantially equal to that of the opening rim
52
c
of the container body
52
. The sidewall of the engagement loop
53
a
extends along the surface of the opening rim
52
c
and is fitted into the opening rim
52
c
of container body
52
. When the engagement loop
53
a
is injection molded, the netting
53
b
is insert-molded and secured to the engagement loop
53
a
as a united body, and at the same time, the top surface of the netting
53
b
becomes the equal level as the top surface of the engagement loop
53
a
. Accordingly, the annular attachment component
53
c
comprised of the engagement loop
53
a
and the netting
53
b
is made into a flat state having no level difference.
The above cosmetic compact case
54
containing the netted refillable container
51
is assembled having a lid
54
a
and a housing
54
b
. That is, both the lid
54
a
and the housing
54
b
have a hinge
54
c
on one end and an engagement projection
54
d
on the other. By rotatably connecting the lid
54
a
to the housing
54
b
through the use of the hinge member
54
c
and by enabling the engagement projections
54
d
to attach to and detach from each other, the cosmetic compact case
54
can be closed and maintain a closed state and can be used in an open state as well.
An engagement ring
54
e
is formed on the inner peripheral surface of the housing
54
b
of the cosmetic compact case
54
and by the engaging of the engagement ring
54
e
to an engagement projection
53
d
formed on the outer peripheral surface of the engagement loop
53
a
attached to the upper portion of the container body
52
of the refillable container
51
, the refillable container
51
is attached to the cosmetic compact case
54
. There is an elastic packing
56
attached to the inner surface of a lid
54
a
of the cosmetic compact case
54
, and the packing
56
fits tightly to the netting
53
b
enabling the prevention of spillage of the powdery cosmetic material
55
when the lid
54
a
is closed.
With thus conventional refillable container, when the lid of the cosmetic compact case is closed and engaged to the housing, the packing pressing against the entire surface of the netting ensures a hermetic state. However, in order to guarantee the hermetic state, it is required for the opening rim of the container body and the engagement loop of the net frame to maintain a molding precision to a certain standard. Therefore, where the components above suffer from bending or deformation and are unable to obtain their intended molding precision, it causes the deterioration of the hermetic state
If the only objective was to intensify the hermetic state, it can be accomplished by protuberating the outer peripheral portion in a ring-like shape higher than the netting at the top surface of the engagement loop of the net frame and by making the outer peripheral portion press against the packing. Furthermore, by forming such projection, it would become unnecessary to maintain a high molding precision. Nevertheless, with this structure, a space will be created between the netting and the packing, which would result to the problem of accumulation of the powdery cosmetic material in the space, for example, due to vibration caused when the cosmetic compact case is carried.
Furthermore, when the netting is insert-molded to the engagement loop, the netting could hardly maintain a sufficiently stretched out state where exerted with a tension perpendicular to the netting, and a slight looseness of the netting would often be created. When such looseness is created, a space may form between the packing and the netting, and would raise a problem of accumulation of the powdery cosmetic material in this space.
It is an object of this invention to provide a netted refillable container
