Abstract
The present invention is directed to a magnetic holder for paper clips or other magnetizable items and substantially in the shape of a wing or an aileron. The items can be removed from within the container by rotating an at least partially magnetic spindle rotatably mounted across an opening through the container, in either of two opposite directions.
Description
The present invention is directed to a clip case, i.e. a holder for small metallic items that are magnetizable such as paper clips, commonly known as gem clips. More particularly, the present invention is directed to such a clip holder or case which facilitates both retention and withdrawal of paper clips therefrom.
Paper clip cases and holders have been available for quite some time to retain small metallic objects that are magnetizable, notably paper clips, e.g., upon an office desk. There is a need to securely retain the gem clips in a case or holder so that the clips do not scatter; at the same time, there is a need to expedite withdrawal of such clips from the case in a smooth, quick manner. Attaining these needs has often been mutually exclusive.
For example, a prior art gem clip holder can be found in Japanese Patent Laid-Open HEI.-2 (1990)-85184 which is directed to an easy-to-use handy case for storing small metallic utensils such as gem clips
12
. According to this prior art embodiment, the container
2
holding the gem clips
12
moves along a cylinder
1
, to come in contact with magnets
5

c
are installed along the cylinder
1
in overlapping fashion with magnetic force lines pointing in the same direction. The device disclosed in HEI.-2 (1990)-85184 can be unstable in that a large container
2
must move up and down a fairly narrow spindle or cylinder
1
. Furthermore, the container
2
is open at the top thereof so clips can be explicitly removed therefrom as shown, e.g., in
FIGS. 6
a-c
. Thus, retained clips
12
are in danger of inadvertently falling out of the open container
2
, especially if the unstable container
2
is jostled and/or knocked over.

SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a new and improved case or holder for small metallic utensils such as paper or gem clips.
It is a more detailed object of the present invention to provide such a gem clip case or holder which facilitates both storage within and withdrawal of the clips therefrom.
It is another object of the present invention to provide a case or holder for gem clips which allows for easy introduction of individual clips thereinto, secure retention of individual clips therein and, at the same time, facilitates withdrawal of the clips therefrom.
It is a further object of the present invention to provide such a container which can be easily manufactured with minimal number of separable components.
It is yet another object of the present invention to minimize need for precise tolerances or clearances in manufacturing such a case or holder.
These and other objects are attained by the present invention which is directed to a case for retaining paper clips or other magnetizable items, comprising a container substantially in the shape of a wing or an aileron. An at least partially magnetized spindle is rotatably mounted upon the container to remove the clips by rotating in either of two opposite directions.
More particularly, the case comprises a container body having a hollow interior for containing and storing the items, and an opening or slit at a front end thereof for removing the clips from the interior. A cylindrical body, i.e. spindle, is rotatably mounted at this front end of the container. At least one, preferably disc-shaped magnet is mounted within the spindle.
When the spindle is rotated, items attracted to the magnetic spindle from within the container interior are rotated outside of the container and easily removed for use. At the same time, clips can be easily and securely stored within the container, e.g., by inserting the clips between the spindle and container or through a lateral opening provided in another side of the container. A space is provided both above and below the rotating spindle.
Thus, not only are paper clips and the like more easily removed from a clip case or holder of the present invention, but the clips are more easily and securely introduced and stored in the inventive clip case, with minimal danger of inadvertently falling out therefrom. The inventive clip case is extremely easy to assemble and use, having a minimal number of separate parts that must be fastened together. Indeed, the only movable part in the inventive case is the rotating spindle, with the main container being integrally formed in a preferred embodiment. When the main container and interior are shaped as a wing or an aileron, with the rotating spindle mounted at a larger open end thereof, ease of introduction, storing and retrieving paper clips is especially facilitated. Precise tolerances or clearances are not required for manufacturing the inventive case which successfully operates over a wide range of clearance between the rotating spindle and container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, case or holder
1
for paper clips
2
is shown which facilitates withdrawal of the clips
2
therefrom. The holder
1
comprises a main container body
3
having an interior space for storing the paper clips
2
. Both the outer container body
3
and inner storage space
4
are preferably in the shape of a wing or an aileron as shown. The higher, open front end of the container
3
has two opposed extensions or arms
5
and
6
for receiving a spindle or cylindrical member
7
.
As shown in
FIG. 5
, the cylindrical member
7
is composed of outer hollow spindle sleeve
9
, with a preferably disc-shaped isotropic ferrite magnet
20
situated within the spindle sleeve
9
, and a cap
11
structured to concentrically fit within and plug the sleeve
9
at an open end thereof and retain the magnet
10
therewithin against an inner shoulder
22
on the sleeve
9
. The opposite open end of the sleeve
9
is sealed by a tapered plug
14
having an axle
12
designed to seat in a notch provided within arm
5
. The opposite end of the cap
11
also comprises an opposite axle
16
designed to seat in a notch
17
of a plug
18
that can be threadingly secured in opening
19
of arm
6
as shown in FIG.
1
. The outer opposite end of arm
5
is closed.
The top edge
20
and bottom edge
21
of the container
3
adjacent the front open end of the container
3
are both curved or bowed in an axial direction of the spindle
7
when inserted between arms
5
and
6
. As a result, the rotating spindle
7
is only supported upon arms
5
and
6
when inserted therein and does neither contacts nor is secured to a bottom surface of the container
3
when rotated, as best seen, e.g., in the sectional and front views of
FIGS. 3 and 4
. In other words, as shown in the front elevational view of
FIG. 4
, there are spaces or slots
4
′ and
4
″ axially defined both above and below the rotating spindle
7
. As such, it is very easy to remove paper clips from within the container
3
, e.g., by merely rotating the spindle
7
in any of two opposite directions for removing the paper clips
2
. For example, spindle
7
can be rotated in the direction of arrow R in the figures to remove clips
2
from within the container
3
. However, by simply rotating spindle
7
in the reverse direction, i.e. R′, magnetic clips attracted upon the spindle
7
can also be removed from within the interior of the container
3
.
In an alternative embodiment of the spindle
7
shown in
FIG. 6
(similar components have been denoted by prime symbols), magnet
10
′ is secured within sleeve
9
′ by resting upon a shoulder
22
′ axially offset from an axial midpoint of the spindle
7
′. Additionally, the tapered end
14
′ is integrally formed with the sleeve
9
′. Either rotating spindle
7
(
FIG. 5
) or
7
′ (
FIG. 6
) can be utilized in the case or holder
1
of the present invention.
There is a lateral opening
23
provided through a side of the container
3
and through which paper clips
2
can be introduced into the container
3
between the top
30
and side leg
5
(there is no opening in the opposite side of the container
3
). A ledge
13
for facilitating guidance of paper clips
2
into the container
3
is situated adjacent opening
23
substantially in the shape of an arrow.
Referring to
FIGS. 3 and 7
, a top surface
30
of the container
3
slopes rearwardly to a curved rear end
31
smaller than the open front end, with the bottom surface
32
of container
3
being substantially flat. Additionally, an interior lateral wall
33
opposite opening
23
and ledge
13
of the container
3
is tapered and curved from front to rear as shown in FIG.
7
.
The inventive container
1
securely retains all paper clips
2
or like magnetic objects introduced through a side thereof by way of opening
23
. At the same time, there is surprisingly no danger of the paper clips inadvertently falling out of the container
3
due to positioning of magnetic spindle
7
, even though the gaps or slots
4
′,
4
″ above and below the rotating spindle
7
are quite large. Thus, paper clips
2
can be securely and reliably retained within the interior of the case
1
and removed therefrom as needed, there being no need to seal opening
23
or reduce clearance about rotating spindle
7
.
The components forming the inventive clip holder
1
(other than the magnet) can be molded from hard plastic or other similar resin, with the spindle
7
, e.g. sleeve
9
, molded from clear or transparent plastic. The paper clips
2
themselves are nonmagnetic but magnetizable.
The preceding description of the present invention is merely exemplary and not intended to limit the scope thereof in any way.
