Description
BACKGROUND OF THE INVENTION
This invention relates to ammunition packs, and more particularly
to a flat, pocket sized pack for ammunition cartridges.
The safe transportation of live ammunition has long received
careful consideration. On the one hand, it must be protected
against damage or premature discharge, yet it should be easily
accessible for use. Proposed solutions to this problem include U.S.
Pat. Nos. 808,854, 847,833 and 3,593,873.
The marksman does not face the same problems as the hunter, or
police and military personnel, since the latter are usually mobile,
continuously armed, and carry reserve ammunition. Whereas marksmen
often prefer the more bulky type of ammunition carriers (such as
illustrated in U.S. Pat. No. D-227,517, assigned to the assignee of
the present invention), the policeman rarely carries his ammunition
in such fashion. Rather, as is well known, the ammunition is
usually carried on a belt, where, if not inconspicuous, it is at
least unrestricting and reasonably comfortable. Unfortunately,
ammunition carried this way is not as accessible as that carried in
bulk.
A need thus exists for a comfortable, inconspicuous and compact
ammunition pack with provides immediate and rapid access to the
ammunition carried therein.
SUMMARY OF THE INVENTION
Briefly, the present invention provides a flat pack for ammunition
cartridges. The pack may be easily slipped into a trousers or shirt
pocket, and the cartridges are securely held within the pack,
whether open or closed, and in any position. When ammunition is
needed the pack may be opened and the cartridges individually and
quickly dispensed with but a single hand. The present invention is
thus particularly well tailored to the needs of hunters, police,
military personnel, and sportsmen in general.
These advantages are provided through a unique fulcrum system which
causes each cartridge to be pried loose from under corresponding
engaging projections whenever the particular cartridge is pressed
downwardly on the end opposite the projections. The engaging
projections resiliently accept and hold the cartridges within
individual compartments in the ammunition pack. The pack may
therefore be held and opened, and the cartridges individually
dispensed, all with but a single hand.
It is therefore an object of the present invention to provide a
flat pack for ammunition cartridges; a compact pack which may be
comfortably carried and which provides rapid and individual access
to the ammunition cartridges; which includes fulcrum means for
prying individual cartridges loose as needed; in which the
cartridges may be actuated against the fulcrum means and released
with the same hand which supports the pack; which may accommodate
variations in cartridge sizes; and to accomplish the above objects
and purposes in an inexpensive, durable, and versatile
configuration particularly well suited for carrying ammunition in a
convenient and comfortable manner.
Other objects and advantages of the invention will be apparent from
the following description, the accompanying drawings and the
appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The flat pack 10 (FIG. 1) of the present invention includes a base
12 connected by a hinge 13 to a lid 14. In the closed position, lid
14 is held against base 12 by latch members 16.
Ammunition cartridges 20 are carried in pack 10 in individual
compartments 22 separated by flexible divider walls 23. Divider
walls 23 are attached along one edge to base 12 and have
projections 25 integrally formed therein on the wall edges opposite
base 12. The projections 25 are "integral" since they are each
formed from the same single piece of material as the wall to which
attached. This is accomplished in the preferred embodiment by
applying a heated bar across the walls 23 to melt them to form the
projections 25 thereon.
Walls 23 are spaced apart somewhat farther than the diameters of
the cartridges 20 in order to accommodate them therein. The
projections 25 project over the compartments leaving spacings 26
therebetween somewhat less than the cartridge diameters, so that
cartridges placed within the compartments 22 are engaged and held
therein by the projections 25. Thus, in order to insert a cartridge
20 into a compartment 22, the cartridge is simply pressed against
the engaging and holding projections 25 and the flexible walls and
projections yield temporarily to accept the cartridge into the
compartment.
The flexible walls 23 and projections 25 similarly yield to release
the cartridgs 20 individually from the compartments 22. Each
cartridge is easily pried loose from the projections 25 by using
the fulcrum means provided in the ammunition pack 10. Thus, the
projections 25 engage the cartridges near the cartridge bases 28,
and a pair of pin means 30 is located intermediate the cartridge
base 28 and base 32 to serve as the above-mentioned fulcrum. The
fulcrum 30 holds the cartridge nose 32 above the base 12 of pack
10, so that, as illustrated in FIG. 5, the cartridge is released by
depressing the cartridge nose 32 toward base 12 with the finger or
thumb 33. Fulcrum pins 30 then pry the cartridge base loose from
under the projections 25 by moving the cartridge base 28 between
the projections and away from the base 12 of the ammunition pack.
Ordinarily, pack 10 may be held in one hand and the thumb of the
same hand used for individually releasing the cartridges.
Pack 10 includes a number of flexible fingers 35 in the
compartments 22 and on the lid 14 which engage and straddle the
cartridges 20 (FIGS. 3 and 4). Fingers 35 serve the dual purpose of
accommodating variations in cartridge sizes within pack 10 and
preventing the cartridges from rattling and shifting about within
the ammunition pack.
Since pack 10 may be carried in the pocket, it includes a separator
wall 37 which bridges the space within pack 10 between the base 12
and lid 14 (FIG. 3). Separator wall 37 is integral with lid 14 and
serves to reinforce the pack in order to maintain a minimum
separation between the lid and base. This protects the pack against
crushing of the lid toward the base, so that a person who sits on
the pack will not crush it.
FIG. 6 illustrates a second version of the present invention in
which the flat pack 40 is essentially the same as pack 10 (FIG. 1)
except that the cartridges and compartments face longitudinally
rather than transversely. In addition, the divider walls 42 fully
surround the cartridge compartments. In this embodiment, the pack
40 is protected against crushing by separating studs 44 which are
integral with the lid 45 and directly engage the divider walls 42
(FIG. 7), which are in turn integral with the base 46.
FIG. 8 illustrates another embodiment in which the pack 50 does not
include the fulcrum pins 30 or fingers 35 of pack 10. Rather, the
base 52 of pack 50 has a raised portion 53 at the bottom of the
individual cartridge compartments 54, similarly as in the other
embodiments. The raised portion 53 forms a shelf, and the edge 55
of the shelf 53 serves as the fulcrum for prying the cartridges
loose from the projections 25. That is, as a cartridge nose 32 is
pressed toward base 52, the cartridge will pivot on the shelf edge
or fulcrum 55 to pry the cartridge base 28 free from the
projections 25.
FIG. 9 illustrates another version wherein a flat pack 60 has
cartridges and compartments arrangement similarly as in pack 40
(FIG. 6), but employes a shelf fulcrum such as in pack 50 (FIG.
8).
FIG. 10 illustrates yet another version which includes a pair of
walls 65 and 66 forming a saddle for supporting a cartridge within
the compartment. The forward wall 65 of the saddle serves as the
fulcrum for prying the cartridge loose from the projections 25.
FIG. 11 illustrates still another version using a shelf 70 similar
to that in FIGS. 8 and 9. However, shelf 70 is inclined to raise
the cartridge nose higher to facilitate removal of the cartridges
as they are pivoted about the shelf edge or fulcrum 71.
As may be seen, therefore, the present invention provides numerous
advantages. The illustrated versions are all designed for
convenient manufacture as a single piece by injection molding, and
the integral engaging and holding projections 25 are easily formed
in the divider walls by melting them therein as discussed
above.
The present invention provides a convenient and compact pack for
carrying ammunition. The pack may be easily carried in a pocket
where it is neither bulky nor conspicious. It may be held
immediately adjacent the weapon as it is reloaded, may be entirely
managed by one hand, and the cartridges are more easily accessible
than when carried in conventional ammunition belts. A variety of
cartridge sizes may be accommodated within each compartment, yet
each is securely held and protected within. The pack is also
reinforced so that it may be safely carried in the pocket without
fear of crushing.
While the forms of apparatus herein described constitute preferred
embodiments of this invention, it is to be understood that the
invention is not limited to these precise forms of apparatus, and
that changes may be made therein without department from the scope
of the invention.
