Claims
I claim:
1. A container for a film magazine having a shaft with a spool
carried thereon, comprising a hollow member having opposite open
ends, a second member adapted to be receivably inserted into said
hollow member from either open end thereof, said second member
being composed of two end plates and an intermediate portion
extending between and connected to the respective end plates along
only a portion of the facing surfaces thereof, said intermediate
portion having a shape corresponding to the shape of the inner wall
surface of said hollow member, said hollow member having an annular
groove disposed adjacent at least one of the open ends and opening
inwardly of said hollow member said second member having, on each
of said end plates, an annular outwardly directed protrusion
adapted to snap-fit in an associated annular groove in said hollow
member when said second member is received therein, said
intermediate portion having, adjacent one of said end plates, a
pair of spaced apart abutment means for receiving therebetween an
end portion of the film magazine shaft projecting from the spool so
as to position the spool between said abutment means and the other
of said end plates, and means defining an opening in said
intermediate portion and said opening is located between said
abutment means and the other of said end plates.
2. A container for a film magazine as defined in claim 1 wherein
said abutment members have an axial length longer than the end
portion of the shaft projecting from the spool.
3. A container for a film magazine as defined in claim 1 wherein
said hollow member is of cylindrical shape.
4. A container for a film magazine as defined in claim 1 wherein
said hollow member is of quadrangular shape.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a container for retaining a film
magazine, and more specifically to a container which serves as a
package as well as retains a cylindrical film magazine for a roll
film.
2. Description of the Prior Art
The conventional film magazines for a 35 mm roll film have been
retained in a plastic or metallic container and further packaged in
a proper packaging box. Accordingly, both hands had to be used to
unpack the package. It has been inconvenient, therefore, to unpack
the film package of commercially available type particularly when
the photographer carries a camera or any other baggage with a
hand.
SUMMARY OF THE INVENTION
In view of the foregoing disposition of the conventional film
package, it is the primary object of the present invention to
provide a container for retaining and packaging a film magazine
which can be unpacked with only one hand.
Another object of the present invention is to provide a film
magazine container which also serves as the outermost package for
the same.
In order to accomplish the above objects of the invention, the film
magazine container in accordance with the present invention is
composed of a single hollow member having opposite open ends and a
slidable member inserted in the hollow member having opposed end
plates serving as end covers of the hollow member. The slidable
member is provided with an opening or cut-away portion for
insertion of a finger to push the film magazine thereout. Further,
the slidable member is provided with at least an abutment
projection at an end thereof so that a relative movement may not be
caused between the magazine body and the shaft thereof projected at
an end thereof out of the body.
The construction of the container of this invention will be fully
understood from the detail description of the preferred embodiments
thereof described hereinafter.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1A is a perspective view of the slidable member of the first
embodiment of the film container in accordance with the present
invention;
FIG. 1B is a perspective view of the hollow member of the first
embodiment of the film container in accordance with the present
invention;
FIG. 2 is a longitudinal sectional view of the first embodiment of
the film magazine container with the slidable member thereof closed
in accordance with the present invention;
FIG. 3A is a perspective view of the slidable member of the second
embodiment of the film magazine container in accordance with the
present invention;
FIG. 3B is a perspective view of the hollow member of the second
embodiment of the invention; and
FIG. 4 is a perspective view of the slidable member of the third
embodiment of the film magazine container in accordance with the
present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring first to FIGS. 1A and 1B, a film magazine container in
accordance with an embodiment of the present invention is composed
of a slidable member 1 and a cylindrical hollow member 2 into which
the slidable member 1 is inserted. The slidable member 1 comprises
a pair of opposed end plates 10A and 10B integrally secured to an
intermediate portion 11 at the opposite ends thereof. The
intermediate portion 11 is provided with an opening 12 for
insertion of a finger to push the film magazine thereout. The
cylindrical hollow member 2 is preferably provided with at least
one annular groove 20 in the vicinity of the open end thereof so
that at least one of the peripheral edges 10a and 10b of the end
plates 10A and 10B may be engaged therewith. The slidable member 1
is thus prevented from loosely slipping out of the hollow member 2
when inserted thereinto in position.
The distance between the inner faces of the opposite end plates 10A
and 10B is made slightly longer than the length of the shaft 30
(FIG. 2) of the spool in the film magazine 3. The slidable member 1
is provided at an end thereof at least one abutment projection 13,
which is preferred to be integrally fixed thereto. The projection
13 is positioned out of the central portion where the shaft 30 of
the spool occupies when the film magazine is loaded in the
container.
The axial length or height of the projection 13 is made slightly
longer than the length of the projected part of the shaft 30 of the
film magazine 3. The distance between the inner face of the end
plate 10A and the face of the projection 13 faced to the end plate
10A is made slightly longer than the axial length of the film
magazine 3. Therefore, even if the container should be accidentally
slipped off and dropped on the floor, there is no fear of
disengagement of a magazine cap from the magazine body caused by an
excessive relative movement between the spool shaft and the body.
Furthermore, by the tight engagement between the slidable member 1
and the hollow member 2 at the grooves 20, the film in the
container can be protected against moisture.
FIG. 2 shows how the film magazine 3 (shown at a broken line) is
retained in the container when the slidable member 1 is inserted in
position in the hollow member 2.
The outer surface of the hollow member 2 may be printed with a
trade name of the film and other letters and designs so that the
container may be displayed in the shop-window.
It will be readily understood that the shape of the container may
not necessarily be cylindrical. One of the examples of the
different shapes is shown in FIGS. 3A and 3B. In FIGS. 3A and 3B,
the container is of quadrangular shape, in which the portions or
elements thereof equivalent to those shown in FIGS. 1A and 1B are
all indicated at the same reference numerals.
Further, it will also be understood that the opening 12 may be a
cut-away portion 12a as shown in FIG. 4. Further, each of the whole
construction of the slidable member 1 and the hollow member 2 can
be made integral by molding.
When using the film or unpacking the container, the container in
accordance with the present invention can be easily unpacked with a
hand even with a gloove. First, an end plate 10A and 10B is pushed
inward lengthwise with a finger to push the slidable member 1 out
of the hollow member 2 and the film magazine 3 is pushed aside with
a finger through the opening 12 or cut-away portion 12a (herein
referred to simply as "an opening"). These unpacking operation can
all be done with only one hand.
