BACKGROUND
[0001] When a compressed gas tank is shipped to a consumer, there
may be a need to protect a valve of the gas tank and provide the
consumer with a washer/gasket for connection of a hose to the valve
of the tank. Typically, the valve may comprise a fluid/gas port
that should be covered for protection against abrasion and/or
contamination. Further, there may be a need to secure the
washer/gasket to the tank valve for removal by the consumer upon
connecting a hose to the valve of the tank. Therefore, a means to
adequately protect the valve of a compressed gas tank, and/or
another valve in general, and secure the washer/gasket to the valve
for a future connection is desirable.

DETAILED DESCRIPTION
[0018] Devices and related methods for multipurpose valve caps are
disclosed herein. As discussed above, when a compressed gas tank is
shipped to a consumer, there may be a need to protect a valve of
the gas tank and provide the consumer with a washer/gasket to be
used in connecting a hose and/or supply line to the valve of the
tank. In examples, the connection point of the valve may be covered
with a plastic cap for protecting the threads and/or the fluid/gas
port. Further, the washer/gasket may be secured to the valve of the
gas tank by a rubber band, zip tie, wire, or the like.
[0019] The present disclosure describes devices that may be used to
cover a connection point of a valve and store a washer/gasket. The
embodiments are described with specificity in order to meet
statutory requirements. However, the description itself is not
intended to limit the scope of this application and/or patent.
Rather, the inventor has contemplated that the claimed invention
might also be embodied in other ways, to include different elements
or combinations of elements similar to the ones described in this
document, in conjunction with other present and/or future
technologies.
[0020] In examples, the devices described herein may be structured
to have a first cavity sized to fit over a portion of a compressed
gas tank valve and a second cavity sized to house a washer therein.
Accordingly, the first cavity and the second cavity may share a
common backplane and may be positioned such that an opening of the
first cavity and an opening of the second cavity are oriented in
opposite directions. Additionally, or alternatively, the first
cavity and the second cavity may be different sizes, such as a
different depth and/or diameter. For example, the first cavity may
have a first depth and diameter and the second cavity may have a
second depth and diameter. In further examples, the first cavity
and the second cavity may be the same size.
[0021] Additionally, or alternatively, the devices may be injection
molded and composed of various materials. For instance, the device
may be completely composed of polypropylene, polyethylene, silicon,
and/or another pliable material. Additionally, or alternatively,
the device may be composed of a combined mixture of the materials
listed above. In even further examples, components of the device
may be composed of different materials. For instance, the first
cavity may be composed of a solid metal alloy while the second
cavity may be composed of a pliable material such as
polypropylene.
[0022] In examples, an inside surface of the first cavity may have
different compositions. For example, the inside surface of the
first cavity may be smooth. In other examples, the inside surface
of the first cavity may comprise female threading sized to mate
with male threading disposed on the valve of the gas tank.
Additionally, or alternatively, the inside surface of the first
cavity may comprise an inner rim. In even further examples, the
inside surface of the first cavity may comprise one or more grooves
to produce added friction between the inside surface of the first
cavity and the gas tank valve.
[0023] The second cavity of the devices described herein may take
many different physical forms and sizes, and should not be limited
in scope by the examples provided herein. For instance, the second
cavity may comprise an inner rim at the distal end of the second
cavity with respect to the common backplane. In examples, the
inside diameter of the inner rim may be smaller than an outside
diameter of the washer. Accordingly, the inner rim may protrude
from the inner surface of the second cavity anywhere from about
2-10 thousandths of an inch (0.002''-0.01''). Additionally, or
alternatively, the second cavity may further comprise one or more
relief cuts in the distal end of the second cavity extending
through the inner rim. The one or more relief cuts may allow for
easier removal of a washer housed within the second cavity. In even
further examples, the second cavity may further comprise a cover
attached to at least a portion of the outside surface of the second
cavity for securing the washer in place. The cover may further be
used in conjunction with the inner rim and/or the one or more
relief cuts described above.
[0024] In examples, the washer may be any device used for enabling
a proper connection between a gas tank valve and another device,
such as a hose, a gauge, and/or a meter. The technical term washer
should not be read as far as to limit the scope of the described
devices. For instance, the technical term washer may encompass
similar terms such as gasket, seal, ring, spacer, and other terms
that would be readily known to those with skill in the art. In
examples the washer may be composed of different materials, such as
nylon, rubber, polypropylene, metal, silicon, and other materials
known in the art. The washer may also have varying dimensions in
thickness and width, and may not be universally sized in an
industry standard.
[0025] The first cavity and/or the second cavity may further
comprise one or more protrusions. For instance, the one or more
protrusions may consist of a connection arm. The connection arm may
further comprise a retainer ring located at the distal end of the
connection arm with respect to the first cavity and the second
cavity. In examples, the retainer ring may be sized such that the
valve of the gas tank may be inserted through the retainer ring. In
this way, the device may be secured to the valve of the gas tank
via the connection arm when the valve is not inserted into the
first cavity.
[0026] The one or more protrusions may also include a tab to assist
in removing the first cavity from a gas tank valve. In examples,
the tab may be disposed at any point along the circumference of the
first cavity. The location of the tab may not be limited however to
the first cavity, and could be, for example, attached to the second
cavity. In further examples, the one or more protrusions may also
include one or more grip tabs to assist a user while squeezing the
device to release a washer housed within the second cavity.
[0027] The present disclosure provides an overall understanding of
the principles of the structure, function, manufacture, and use of
the devices and methods disclosed herein. One or more examples of
the present disclosure are illustrated in the accompanying
drawings. Those of ordinary skill in the art will understand that
the devices and methods specifically described herein and
illustrated in the accompanying drawings are non-limiting
embodiments. The features illustrated or described in connection
with one embodiment may be combined with the features of other
embodiments, including as between devices and methods. Such
modifications and variations are intended to be included within the
scope of the appended claims.
[0028] Additional details are described below with reference to
several example embodiments.
[0029] FIG. 1 is an example system 100 illustrating how a
multipurpose valve cap may be used. As shown in FIG. 1, the system
100 may comprise a compressed gas tank 102, a valve 104, and the
valve cap 106.
[0030] In examples, the compressed gas tank 102 may be a CO.sub.2
cylinder, such as a CO.sub.2 cylinder used in a soda fountain. In
other instances, the compressed gas tank 102 may be an oxygen tank,
nitrogen tank, helium tank, and/or the like. The compressed gas
tank 102 may further exist in many different sizes, and may not be
limited to a single industry. For example, the compressed gas tank
102 may be an oxygen tank for use in welding.
[0031] As shown by FIG. 1, the valve 104 may be attached to the
compressed gas tank 102. In examples, the valve 104 may be composed
of different materials. For example, the valve may be composed of
brass, aluminum, copper, iron, and/or some other material known in
the art. The valve 104 may comprise one or more connection points
for attaching a hose and/or supply line.
[0032] The valve cap 106 may be sized to cover a portion of the
valve 104. In examples, the valve cap 106 may cover a threaded
portion of the valve 104. In other examples, the valve cap 106 may
cover the entire valve 104.
[0033] The valve cap 106 may comprise a retainer ring and a
connection arm that further secure the valve cap 106 to the gas
tank valve 104. For example, the retainer ring and connection arm
may keep the valve cap attached to the gas tank valve 104 when a
hose is connected to the connection point of the valve 104 and the
fluid/gas port does not need to be protected by the valve cap 106.
In this way, when the hose is later disconnected, the connection
point of the gas tank valve 104 may be re-inserted into the valve
cap 106 for protection.
[0034] The valve cap 106 may further house a washer 108. The washer
108 may be removed from the housing of the valve cap 106 and may be
used in establishing a proper connection between a connection point
of the gas tank valve 104 and an attaching hose line. In examples,
the washer 108 may be re-inserted into the valve cap 106 after
disconnecting the attaching hose line. Accordingly, the washer 108
may be stored for later use. In examples, the washer 108 may
include one or more protrusions and/or bulges configured to mate
with and/or sink into grooves in a hose fitting and/or tank valve
and/or grooves within the second cavity.
[0035] As noted above, the valve cap 106 may be advantageous in
comparison to traditional valve caps. For example, because the
valve cap 106 may house a washer 108, other means for securing the
washer 108 to the gas tank valve 104 for shipping to a consumer may
not be necessary. Additionally, or alternatively, the valve cap 106
may secure the washer 108 to the gas tank valve 104 more safely
and/or effectively, therefore preventing the washer 108 from being
disconnected from the gas tank valve 104 during shipping.
[0036] FIG. 2 illustrates a perspective view of an example
multipurpose valve cap. As shown, the exemplary device 200 may have
several different components.
[0037] The exemplary device 200 may comprise a first cavity 202
sized to cover at least a portion of a gas tank valve. In examples,
the first cavity 202 may have a first diameter and a first cavity
depth. The first cavity 202 may further comprise threading on the
inside surface of the cavity sized to mate with threading on the
gas tank valve 106. In other examples, the inside surface of the
first cavity 202 may be smooth, such that the first cavity may
slide over threading disposed on the gas tank valve 106.
[0038] The exemplary device 200 may also comprise a second cavity
204. The second cavity 204 may be sized to house a washer 108
therein, and may share a common backplane 206 with the first
cavity. As shown, the orientation of the second cavity 204 may be
in a direction opposite that of the first cavity 202. In examples,
the second cavity 204 may have a second diameter and a second
cavity depth. For example, the second diameter and second cavity
depth may each be different than the first diameter and first
cavity depth of the first cavity 202. In other examples, the first
cavity depth and the second cavity depth may be the same.
Additionally, or alternatively, the first cavity diameter and the
second cavity diameter may be the same.
[0039] The second cavity 204 may further comprise an inner rim
disposed at the distal end of the second cavity with respect to the
common backplane 206. In examples, the inner rim may have an inside
diameter that is smaller than an outside diameter of the washer
108, thereby enabling the second cavity 204 to retain the washer
108. In other examples, the second cavity 204 may comprise a cover
that is attached to at least a portion of the exemplary device 200.
For example, the cover may be sized to fit over the second cavity
to secure the washer 108 within the second cavity.
[0040] In examples, the second cavity 204 may further comprise a
relief cut. For instance, the second cavity 204 may comprise a
relief cut extending from the common backplane 206 to the distal
end of the second cavity with respect to the common backplane 206.
The relief cut may assist in removing the washer 108 that may be
housed in the second cavity 204.
[0041] As noted above, the exemplary device 200 may comprise a
washer 108. The washer 108 may be used for connecting a hose and/or
other device to the gas tank valve 104. In examples, the washer 108
may be composed of various materials. For instance, the washer 108
may be composed of nylon, rubber, silicon, polypropylene, metal,
and/or another substance.
[0042] As mentioned above, the exemplary device 200 may comprise a
common backplane 206 joining the first cavity 202 with the second
cavity 204. In examples, the common backplane 206 may vary in
thickness depending on the size of the first cavity 202 and the
second cavity 204. For example, the common backplane 206 may be
thin, thereby creating a more pliable device that may be easier to
remove a washer from. Alternatively, the common backplane 206 may
be thicker to produce a more rigid device that is not easily
manipulated.
[0043] In examples, the first cavity 202 and the second cavity 204
of the exemplary device 200 may be two separate components that are
coupled together with the common backplane 206 separating the two
components. In other examples, the first cavity 202 and the second
cavity 204 may be a single component such that the common backplane
206 comprises at least a portion of the first cavity 202 and at
least a portion of the second cavity 204.
[0044] Additionally, or alternatively, the exemplary device 200 may
comprise one or more protrusions. The one or more protrusions may
include a connection arm 208. In examples, the connection arm 208
may comprise a retainer ring 210 sized to fit over a valve
connection point of the gas tank valve 104. In this way, the valve
connection point may be inserted through the retainer ring 210
before inserting the valve connection point into the first cavity
202. Accordingly, when the first cavity is removed from the valve
connection point, the retainer ring 210 may keep the exemplary
device 200 connected to the gas tank valve 104.
[0045] In examples, the one or more protrusions may also include a
tab 212 for assisting a user of the exemplary device 200 in
removing the first cavity 202 from the valve connection point of
the gas tank valve 104. In this way, the tab 212 may assist the
user by providing leverage and/or additional grip to pry the first
cavity 202 away from the connection point of the gas tank valve
104.
[0046] FIG. 3A illustrates an example multipurpose valve cap with
force applied to displace a washer associated with the cap. When
the exemplary device 200 is squeezed by a user 302, the device may
release the washer 108 from the second cavity 204.
[0047] In examples, the user 302 may apply a threshold amount of
force to the exemplary device 200 to release the washer 108 housed
within the second cavity 204. For example, the user 302 may squeeze
the device in a direction about parallel to the common backplane of
the exemplary device 200 to release the washer 108. In other
examples, the user 302 may pry the washer 108 out of the second
cavity 204.
[0048] FIG. 3B illustrates an example multipurpose valve cap
utilized to press a washer into the cap for storage. When the
washer 108 is pressed into the second cavity 204 of the exemplary
device 200 with a threshold amount of force, the second cavity 204
may retain the washer 108 therein.
[0049] In examples, a user 302 may snap the washer 108 into the
second cavity 204 if the second cavity comprises an inner rim for
retaining the washer 108. Accordingly, depending on the inside
diameter of the inner rim, the threshold amount of force applied by
the user 302 may vary.
[0050] FIG. 4 illustrates an example multipurpose valve cap being
connected to a compressed gas tank valve while the valve is
connected to a hose. As shown in FIG. 4, the washer 108 may be
removed from the valve cap 106 and thereby used for connecting a
hose 402 to a connection point 404 of a gas tank valve 104.
[0051] In examples, when the gas tank 102 is in use and a hose 402
is attached to the connection point 404 of the gas tank valve 104,
the connection arm and retainer ring keep the device 106 connected
to the gas tank valve 104. In this way, if the hose 402 is later
disconnected, the connection point 404 may be re-inserted into the
device 106 to protect against abrasion, contamination, and/or the
like. Additionally, the washer 108 may be re-inserted into the
second cavity of the device 106 if desired for storage until a new
connection may be desired.
[0052] FIG. 5 illustrates a cross-sectional view of an example
multipurpose valve cap. As shown in more detail in FIG. 5, the
exemplary device 200 may comprise a common backplane 206 where the
distal ends of the first cavity and the second cavity may be
disposed. Additionally, as noted above and shown in more detail in
FIG. 5, the first cavity and the second cavity may be a single
component such that the common backplane 206 comprises at least a
portion of the first cavity and at least a portion of the second
cavity.
[0053] Additionally, or alternatively, the thickness of the common
backplane 206 may vary depending on the desired pliability of the
exemplary device 200. For instance, the common backplane 206 may be
sized thicker to create a more rigid exemplary device 200.
Alternatively, the common backplane 206 may be sized thinner to
create a less rigid exemplary device 200.
[0054] FIG. 6 illustrates a cross-sectional view of an example
multipurpose valve cap with an example relief cut. In examples, the
second cavity may have one or more relief cuts 602 extending from
the common backplane through the distal end of the second cavity.
The one or more relief cuts 602 may assist the user in releasing
the washer from the second cavity. For example, the one or more
relief cuts 602 may cause the second cavity to be more pliable and
more easily manipulated for a user to release the washer.
[0055] In examples, the one or more relief cuts 602 may be spaced
at even intervals around the circumference of the second cavity if
the total number of relief cuts 602 is greater than one.
Additionally, or alternatively, the one or more relief cuts 602 may
vary in thickness. For example, if a more pliable second cavity is
desired, more material from the second cavity may be removed when
the one or more relief cuts 602 are inserted. Alternatively, if a
less pliable second cavity is desired, less material from the
second cavity may be removed when the one or more relief cuts 602
are inserted.
[0056] FIG. 7A illustrates a cross-sectional view of an example
multipurpose valve cap comprising an inner rim for holding a washer
in place. As shown in FIG. 7A, the inner rim 702 may be disposed on
the second cavity at the distal end of the cavity with respect to
the common backplane. In examples, the inside diameter of the inner
rim 702 may be smaller than an outside diameter of the washer.
Accordingly, the inner rim 702 may protrude from the inner surface
of the second cavity anywhere from about 2-10 thousandths of an
inch (0.002''-0.01'').
[0057] In examples, the inner rim 702 may be a single, solid rim
disposed on the entire inside circumference of the second cavity of
the exemplary device 200. In other examples, the inner rim 702 may
be a series of one or more intermittent "bumps" evenly spaced along
the inside circumference of the second cavity.
[0058] FIG. 7B illustrates a cross-sectional view of an example
multipurpose valve cap comprising grip tabs. In examples, the
exemplary device 200 may have one or more grip tabs 704. The one or
more grip tabs 704 may assist a user in squeezing the exemplary
device 200 to release the washer from the second cavity.
[0059] As noted earlier, the exemplary device 200 may be composed
of a pliable material. Such pliable material may be tough for a
user to grip for squeezing the exemplary device 200 in order to
release the washer from the second cavity. In examples, the one or
more grip tabs 704 may make the exemplary device 200 easier to hold
when squeezing the exemplary device 200. Additionally, or
alternatively, the one or more grip tabs 704 may assist in
inserting the connection point of the gas tank valve into the first
cavity of the exemplary device 200 for protection.
[0060] FIG. 7C illustrates a cross-sectional view of an example
multipurpose valve cap comprising internal threads. In examples,
the inside surface of the first cavity of the exemplary device 200
may comprise female threading 706 sized to mate with male threading
disposed on the connection point of the gas tank valve. In this
way, the first cavity of the exemplary device 200 may be threaded
onto the connection point of the gas tank valve rather than pressed
on.
[0061] Additionally, or alternatively, the outside surface of the
second cavity may comprise male threading sized to mate with female
threading disposed on the connection point of the gas tank valve.
In this way, the device 200 may be mated with both male and/or
female gas tank valves.
[0062] FIG. 7D illustrates a cross-sectional view of an example
multipurpose valve cap comprising a cover for holding the washer in
place. In examples, the second cavity of the exemplary device 200
may further comprise a cover 708. The cover 708 may be attached to
at least a portion of an outside surface of the first cavity and/or
the second cavity. The cover 708 may be sized to enclose the second
cavity and thereby secure the washer in place.
[0063] Additionally, or alternatively, the cover 708 may further be
used in conjunction with the inner rim and/or the one or more
relief cuts described above. In this way, the washer may be more
securely housed within the second cavity.
[0064] FIG. 8 is a flow diagram illustrating an example process for
use of a multipurpose valve cap. The process 800 may be performed
by a user of the device, a machine, and/or another operator capable
of performing the example process.
[0065] The process 800 (as well as each process described herein)
is illustrated as a logical flow graph, each operation of which
represents a sequence of operations that can be implemented by a
user. The order in which the operations are described is not
intended to be construed as a limitation, and any number of the
described operations can be combined in any order and/or in
parallel to implement the process. Further, any number of the
described operations may be omitted.
[0066] At 802, the process 800 may begin by connecting the
exemplary device to the gas tank valve with the retainer ring. In
doing this, the connection point of the gas tank valve may be
inserted through the retainer ring of the device.
[0067] At 804, the first cavity of the exemplary device may be
mated with the connection point of the gas tank valve. As described
above, in examples the first cavity of the exemplary device may be
pressed onto the connection point, while in other examples the
first cavity may be threaded onto the connection point via
threading disposed on a surface of the first cavity.
[0068] At 806, the washer may be pressed into the second cavity for
storage. In examples, the washer may snap into the second cavity if
the second cavity comprises an inner rim. Additionally, or
alternatively, the washer may be secured by a cover that encloses
the washer within the second cavity.
[0069] At 808, the first cavity of the exemplary device may be
removed from the connection point of the gas tank valve. In doing
this, a tab of the exemplary device may be pulled on for removing
the first cavity from the connection point. Alternatively, or
additionally, the first cavity may be un-threaded from the
connection point.
[0070] At 810, the exemplary device may be squeezed with a
threshold amount of force in order to release the washer from the
second cavity of the exemplary device. Grip tabs may be used to
grip the exemplary device easier while squeezing. Alternatively, or
additionally, the cover may be removed from the second cavity
before removing the washer.
[0071] At 812, the second cavity of the exemplary device may
release at least a portion of the washer. The washer may then be to
connect a hose to the gas tank valve.
[0072] FIG. 9 illustrates a perspective view of an example
multipurpose valve cap 900.
[0073] The exemplary device 900 may comprise a first cavity 902
sized to cover at least a portion of a gas tank valve. In examples,
the first cavity 902 may have a first diameter and a first cavity
depth. The first cavity 902 may be constructed of a pliable
material such that the first cavity 902 may at least partially
stretch to receive the portion of the gas tank valve. The first
cavity 902 may also include a removable tab 904, which may, when
pulled by a user, cause the removable tab 904 to at least partially
break away and/or pull apart from the rest of the first cavity 902.
By so doing, a user may gain access to the portion of the gas tank
valve. The removable tab 904 may provide a visual indication that
the gas tank valve has or has not been accessed.
[0074] The exemplary device 900 may also comprise a second cavity
906. The second cavity 906 may be sized to house a washer 108
therein, and may share a common backplane 908 with the first cavity
902. As shown, the orientation of the second cavity 906 may be in a
direction opposite that of the first cavity 902. In examples, the
second cavity 906 may have a second diameter and a second cavity
depth. For example, the second diameter and second cavity depth may
each be different than the first diameter and first cavity depth of
the first cavity 902. In other examples, the first cavity depth and
the second cavity depth may be the same. Additionally, or
alternatively, the first cavity diameter and the second cavity
diameter may be the same.
[0075] The second cavity 906 may further comprise an inner rim
disposed at the distal end of the second cavity 906 with respect to
the common backplane 908. In examples, the inner rim may have an
inside diameter that is smaller than an outside diameter of the
washer 108, thereby enabling the second cavity 906 to retain the
washer 108. In other examples, the second cavity 906 may comprise a
cover that is attached to at least a portion of the exemplary
device 900. For example, the cover may be sized to fit over the
second cavity to secure the washer 108 within the second cavity. In
other examples, a pull tab 910 may be removably coupled to at least
a portion of the second cavity 906 such that the washer 108 is
secured in the second cavity 906 by the pull tab 910. In examples,
the pull tab 910, when coupled to the second cavity 906, may
provide a sanitary and/or clean environment for the washer 108
until the pull tab 910 is removed. The pull tab 910 may also
provide a visual indication to a user of the device 900 that the
washer 108 has not been utilized and/or the tank has not been
used.
[0076] As noted above, the exemplary device 900 may comprise a
washer 108. The washer 108 may be used for connecting a hose and/or
other device to the gas tank valve. In examples, the washer 108 may
be composed of various materials. For instance, the washer 108 may
be composed of nylon, rubber, silicon, polypropylene, metal, and/or
another substance.
[0077] As mentioned above, the exemplary device 900 may comprise a
common backplane 908 joining the first cavity 902 with the second
cavity 906. In examples, the common backplane 908 may vary in
thickness depending on the size of the first cavity 902 and the
second cavity 906. For example, the common backplane 908 may be
thin, thereby creating a more pliable device that may be easier to
remove a washer from. Alternatively, the common backplane 908 may
be thicker to produce a more rigid device that is not easily
manipulated.
[0078] Additionally, or alternatively, the exemplary device 900 may
comprise one or more protrusions. The one or more protrusions may
include a connection arm 912. In examples, the connection arm 912
may comprise a retainer ring 914 sized to fit over a valve
connection point of the gas tank valve. In this way, the valve
connection point may be inserted through the retainer ring 914
before inserting the valve connection point into the first cavity
902. Accordingly, when the first cavity 902 is removed from the
valve connection point, the retainer ring 914 may keep the
exemplary device 900 connected to the gas tank valve. In examples,
a retention tooth on the interior wall of the device 900 may be
replaced with an annular retention ring 914. The annular retention
ring 914 may be manufactured and/or formed utilizing a floating
core in the mold used to make the device 900. In other examples,
the device 900 may include the annual retention ring 914 and a
retention tooth.
[0079] FIG. 10 illustrates a perspective view of another example
multipurpose valve cap 1000. The device 1000 may be the same or
similar to the device 900 described with respect to FIG. 9. For
example, the device 1000 may include a first cavity 902, a
removable tab 904, a second cavity and a common backplane (not
shown as covered by a pull tab 910), a connection arm 912, and/or a
retainer ring 914. These components may function in the same or a
similar manner to the components described with respect to FIG.
9.
[0080] As shown in FIG. 10, the pull tab 910 may be removably
coupled to other portions of the device 1000. For example, the pull
tab 910 may be coupled to at least a portion of the removeable tab
904, at least a portion of the first cavity 902, at least a portion
of the second cavity, and/or at least a portion of the connection
arm 912. When coupled, the pull tab 910 may provide a substantially
air tight and/or water tight seal to the second cavity, which may
hold the washer 108 therein. The pull tab 910, in examples, may
include one or more writings, such as advertising and/or coloring
for color codes, which may be used by one skill in the art to
identify the washer and/or type of washer held within the second
cavity. Once a user pulls the pull tab 910, it may be removed from
the rest of the device 1000, revealing the washer 108.
Additionally, or alternatively, pulling on the removable tab 904
may cause the pull tab 910 to break and/or separate from the second
cavity.
[0081] FIG. 11 illustrates a cross-sectional view of an example
multipurpose valve cap 1100. The device 1100 may be the same or
similar to the device 900 described with respect to FIG. 9. For
example, the device 1100 may include a first cavity 902, a
removable tab 904, a second cavity 906, a common backplane 908, a
pull tag 910, a connection arm 912, and/or a retainer ring 914.
These components may function in the same or a similar manner to
the components described with respect to FIG. 9.
[0082] As shown in FIG. 11, the washer 108 may be housed within the
second cavity 906, such as between the common backplane 908 and the
pull tag 910. When coupled, the pull tab 910 may provide a
substantially air tight and/or water tight seal to the second
cavity, which may hold the washer 108 therein. The pull tab 910, in
examples, may include one or more writings, such as advertising
and/or coloring for color codes, which may be used by one skill in
the art to identify the washer and/or type of washer held within
the second cavity. Once a user pulls the pull tab 910, it may be
removed from the rest of the device 1100, revealing the washer 108.
Additionally, or alternatively, pulling on the removable tab 904
may cause the pull tab 910 to break and/or separate from the second
cavity.
