Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to the use of
portable water storage devices and more particularly to an
apparatus used in conjunction with a standard canteen.
[0003] 2. Background Art
[0004] The use of portable water storage containers such as the
flask and the canteen is well known, with many varieties being made
available for use all over the world. One of the most well known
versions is the standard military issue canteen employed by the
military forces of the United States of America and other countries
as well. The standard design of this canteen has not changed for
decades and is well known to all those who have served in the
various branches of the military. The canteen is used to store and
transport water or other beverages so that the user of the canteen
will have ready access to liquids on an as-needed or as-desired
basis.
[0005] In one of the most commonly known embodiments of the
standard military issue canteen, both the canteen and the cup have
a substantially rounded kidney-shaped or reniform cross section,
thereby adapting the canteen for deployment in conjunction with a
belt to be worn on the hip. In this most basic form, the canteen is
typically fitted with a screw on lid and the canteen is removably
placed into the form-fitting cup portion that can be used to
contain liquid poured from the canteen, thereby providing liquid
for consumption. The reniform cross section provides a canteen may
be worn against the waist/hip of a human and thereby provides for a
canteen that can be comfortably carried on the hip in close
proximity to the body.
[0006] While the basic design of the standard military issue
canteen has been broadly accepted over the years, the presently
known military canteen is not without certain drawbacks. This
situation is evidenced by the large number of accessory objects
that have been developed for use with the standard military issue
canteen. For example, cups with foldable and/or retractable handles
have been implemented. Various types of canteen covers, including
insulated covers to keep the contents of the canteen hot or cold,
have also been developed and implemented with some degree of
success. In addition, various types of heating elements,
drink-through-the-cap straws, etc. have also been adopted in a wide
variety of applications.
[0007] While these various adaptations for improving the
functionality of the canteen have shown various levels of adoption,
some shortcomings remain. For example, once a liquid is poured into
the canteen cup, there is no way to cover the liquid contained in
the cup. This can be a problem in those instances where a campfire
is present or where dust and debris are airborne, allowing for
possible contamination of the liquid contained in the cup.
Additionally, the use of the cup to contain liquid poured from the
canteen also leaves the liquid subject to "sloshing" out of the
cup, thereby reducing the amount of liquid available for
consumption.
[0008] Accordingly, without some additional improvements in the
state-of-the-art for standard canteens, including the well-known
military issue canteen, access to and consumption of liquid from
the canteen will continue to be sub-optimal.
SUMMARY OF THE INVENTION
[0009] The apparatus of the present invention implements a cover
that can be deployed in conjunction with the standard military
issue canteen and cup. The canteen cup cover is most preferably
manufactured from a durable and flexible food-grade material. The
cross-section of the cover features a ridge and groove arrangement
that has been specifically configured to receive the edge of the
canteen cup, which typically forms approximately a 45.degree. angle
with the body portion of the canteen cup. The cover may be
selectively attached to and removed from the canteen cup, thereby
providing enhanced functionality for the canteen cup.

DETAILED DESCRIPTION
[0019] The apparatus of the present invention implements a cover
that can be deployed in conjunction with the standard military
issue canteen and cup. The canteen cup cover is most preferably
manufactured from a durable and flexible food-grade material. The
cross-section of the cover features a ridge and groove arrangement
that has been specifically configured to receive the edge of the
canteen cup, which typically defines approximately a 45.degree.
angle with the body portion of the canteen cup. The cover may be
selectively attached to and removed from the canteen cup, thereby
providing enhanced functionality for the canteen cup.
[0020] Referring now to FIG. 1, a standard military issue canteen
110 and cup 120 are shown. As shown in FIG. 1, the main body of
canteen 110 is formed so as to be removably inserted into cup 120
whenever cup 120 is not in use. This allows cup 120 to be easily
carried with canteen 110 and provides a certain ease of use when
storing the combination of canteen 110 and cup 120. The combination
of canteen 110 and canteen cup 120 are typically carried in a belt
container that is worn around the hips of the user.
[0021] Lid 130 is typically a screw-type lid that can be removed to
provide access to the interior of canteen 110. In normal usage, lid
130 is removed from canteen 110 and a liquid is poured into canteen
110. Then, lid 130 is replaced, thereby securing the contents of
canteen 110. Whenever the user wants to dispense liquid from
canteen 110, lid 130 is removed and the liquid contained within
canteen 110 can be consumed directly from canteen 110 or poured
into canteen cup 120 and then consumed from canteen cup 120. In
either case, lid 130 will then be placed back into position on
canteen 110.
[0022] Those skilled in the art will recognize that canteen cup 120
typically has a flared "lip" around the rim that protrudes
outwardly from the body of canteen cup 120 at approximately a
45.degree. angle. This lip serves several purposes. First, the
outward protrusion of the lip provides an opening that is tapered
and slightly larger at the top than at the bottom of canteen cup
120. This allows canteen 110 to be easily inserted into the open
mouth portion of canteen cup 120. As canteen 110 is inserted into
canteen cup 120 by exerting a downward pressure, the slightly
narrowing body of canteen cup 120 will frictionally contact the
surface of canteen 110, thereby providing a snug "holster" for
canteen 110. Additionally, the outwardly protruding lip or edge of
canteen cup 120 provides a more functional drinking cup for the
user of canteen cup 120.
[0023] Referring now to FIG. 2, a perspective view of a canteen cup
cover 200 in accordance with a preferred exemplary embodiment of
the present invention is depicted. As shown in FIG. 2, the most
preferred embodiments of canteen cup cover 200 will be
substantially reniform in shape and will be sized to fit over the
opening of canteen cup 120 of FIG. 1. The size and shape of canteen
cup cover 200 are carefully selected so as to ensure that canteen
cup cover 200 will fit snugly and tightly over the opening of
canteen cup cover 200, thereby protecting the contents of canteen
cup 120 from accidental spillage or inadvertent contamination due
to airborne contaminants and/or other adverse environmental
conditions.
[0024] Canteen cup cover 200 is most preferably manufactured from a
food-grade plastic or silicone-type material that is both durable
and flexible. Those skilled in the art will recognize that many
plastic and plastic-like materials may be suitably employed for the
fabrication of canteen cup cover 200. The use of a durable material
in fabricating canteen cup cover 200 is desirable so as to permit
long-term usage of canteen cup cover 200 without undesirable
degradation of the performance of canteen cup cover 200. The use of
a flexible material in fabricating canteen cup cover 200 is
desirable so as to ensure that canteen cup cover 200 will fit
snugly and securely over the opening of canteen cup 120 of FIG.
1.
[0025] Referring now to FIG. 3, a plan view of a canteen cup cover
300 in accordance with an alternative preferred exemplary
embodiment of the present invention is depicted. In addition to the
previous characteristics of canteen cup cover 200 described in
conjunction with FIG. 2, canteen cup cover 300 most preferably
comprises an access spout 310. Access spout 310 is provided to
permit access to the contents of canteen cup cover 300 without the
necessity of removing canteen cup cover 300. In the most preferred
embodiments of canteen cup cover 300, access spout 310 comprises a
sealing mechanism placed over an aperture or opening formed in
canteen cup cover 300.
[0026] In the most preferred embodiments of canteen cup cover 300;
access spout 310 is also fabricated from a food-grade plastic or
silicone-type material that is both durable and flexible. Those
skilled in the art will recognize that there are many types of
access spouts suitable for deployment in conjunction with canteen
cup cover 300 and any such access spout known to those skilled in
the art may be utilized. For example, access spout 310 may comprise
a hinged flap that is resealably positioned over the aperture
formed in canteen cup cover 300.
[0027] Referring now to FIG. 4, a side view of a canteen cup cover
200 of FIG. 2 in accordance with a preferred exemplary embodiment
of the present invention is depicted.
[0028] Referring now to FIG. 5, a side view of canteen cup cover
300 of FIG. 3 is depicted. As shown in FIG. 5, Access spout 310 is
provided to permit access to the contents of canteen cup cover 300
without the necessity of removing canteen cup cover 300. As shown
in FIG. 5, access spout 310 is a repositionable access spout and
can be rotated up and away from canteen cup cover 300. Those
skilled in the art will recognize that repositionable access spouts
are presently available in products such as sports bottles and the
like.
[0029] Referring now to FIG. 6, a sectional view of canteen cup
cover 200 of FIG. 2 is shown. As shown in FIG. 6, a narrow groove
610 is fabricated into the interior portion of canteen cup cover
200. Groove 610 is formed at substantially a 45.degree. angle with
reference to top surface 605 and bottom surface 615 as well as each
sidewall surface 625. Given that the overall perimeter length of
groove 610 is slightly less than the perimeter of canteen cup 120
of FIG. 1, canteen cup cover 200 can be manipulated into place only
by slightly stretching the material that comprises canteen cup
cover 200 and forcing the flared lip of canteen cup 120 of FIG. 1
into groove 610.
[0030] Once positioned over the lip of canteen cup 120 of FIG.1,
canteen cover 200 will be held in place by the interaction of
oppositional forces stretching groove 610 over the lip of canteen
cup 120 of FIG. 1. Additionally, given that the angle of groove 610
is manufactured to match the angle of the flared lip of canteen cup
120 of FIG. 1, the inner edge and the outer edge of the flared lip
of canteen cup 120 of FIG. 1 are engaged and covered by the face of
groove 610. In this fashion, the interior surface of groove 610 is
able to form a tight and substantially leak-proof seal along the
surface of both the inner and the outer surface of the lip of
canteen cup 120 of FIG. 1.
[0031] Referring now to FIG. 7, a sectional view of a flared lip
705 of canteen cup 120 of FIG. 1 is depicted. As shown in FIG. 7,
flared lip 705 has both an inner surface 720 and an outer surface
710. Flared lip 705 will generally gradually angle away from the
interior of canteen cup 120, forming various angles with respect to
the body of canteen cup 120. As shown in FIG. 7, this includes an
overall angle that is substantially equal to 45.degree.. This
orientation of flared lip 705 provides an engagement means for
selectively attaching and removing canteen cup cover 200 to canteen
cup 120, thereby protecting the contents of canteen cup 120.
[0032] Referring now to FIG. 7A, a sectional view of flared lip 705
of canteen cup 120 of FIG. 1 with canteen cover 200 of FIG. 1 in
place is depicted. As shown in FIG. 7A, groove 610 of canteen cup
cover 200 of FIG. 6 has engaged flared lip 705 of canteen cup 120
of FIG. 7. In the most preferred embodiments of the present
invention, the thickness of the body of canteen cup 120, including
flared lip 705, is slightly larger than the width of groove 610. By
stretching groove 610 over flared lip 705, a comparatively tight
seal can be obtained. Additionally, as previously explained, the
perimeter of canteen cup 120 is slightly larger than the linear
length defined by groove 610. Stretched in place, groove 610 is in
substantial contact with both inner surface 720 and an outer
surface 710, thereby ensuring a snug fit and tight seal.
[0033] In at least one preferred embodiment of the present
invention, canteen 110 and canteen cup 120 of FIG. 1 will be
offered in a kit form including canteen cup cover 200 of FIG. 2 or
canteen cup cover 300 of FIG. 3. Alternatively, canteen cup cover
200 of FIG. 2 and/or canteen cup cover 300 of FIG. 3 will be
available for purchase separately as after-market products.
[0034] In summary, the present invention provides an effective and
efficient means of covering the liquid contained in a canteen cup.
The canteen cup cover of the present invention comprises a unique
ridge and groove that is specifically designed to receive the
flared edge or lip of a standard metal canteen cup. In this
fashion, the liquid or other contents of the canteen cup can be
secured against inadvertent spillage or undesirable contamination
from environmental sources such as airborne dirt and debris.
[0035] Lastly, it should be appreciated that the illustrated
embodiments are preferred exemplary embodiments only, and are not
intended to limit the scope, applicability, or configuration of the
present invention in any way. Rather, the foregoing detailed
description provides those skilled in the art with a convenient
road map for implementing a preferred exemplary embodiment of the
present invention. Accordingly, it should be understood that
various changes may be made in the function and arrangement of
elements described in the exemplary preferred embodiments without
departing from the spirit and scope of the present invention as set
forth in the appended claims.
