Description
BACKGROUND
[0001] The present disclosure relates to refuse containers, and
more particularly to a refuse container having a latching mechanism
for securing the lid to the container body to prevent or discourage
animals from removing the lid while allowing users, such as refuse
collectors, to detach the latching mechanism and remove the lid
from the container body.
[0002] Various refuse containers configured to secure the lid to
the refuse container have been previously described. For example,
U.S. Pat. No. 4,691,840 to Ferbrache discloses a trash container
comprising a receptacle base, a lid component, and a pair of
handles mounted to opposite sides of the receptacle. Each handle is
pivotally mounted to a side of the receptacle base and provides
integral eccentric cam lobes which, as the handle is pivoted
upward, rotate against the receptacle sidewalls into an upright
locking position. Simultaneously, an outward projecting locking
tooth from each handle penetrates a receptive groove in the
container lid to secure the lid to the receptacle.
[0003] U.S. Pat. Nos. 4,558,796 and 4,666,054 to Jaicks disclose
storage containers forming compartments for storing garbage and
edibles. The compartments are kept sealed from entry by wild
animals by the lid members being threadable onto the container
member. A plurality of vertically extending hand grips are
connected to the lid members at angular intervals. In the '796
patent, a plurality of hold down flange members are connected to
the bottom of the container at angular intervals so that a user can
hold the container member against the support surface with one or
both feet while threading the lid onto or from the container
member. In the '054 patent, a plurality of peripheral recesses are
formed at angular intervals around the rim of the bottom wall of
the container that are adapted to receive the forward part of the
foot of a user so the user can hold the container member against
the support surface with one or both feet while threading the lid
onto or from the container member.
[0004] U.S. Pat. No. 4,331,310 to Silva et al. discloses a
supporting apparatus for a refuse container and the lid for such
container. The apparatus includes a bracket mountable on an upright
and a support pivotally mounted to the bracket between a lower
generally horizontal position and an upper generally vertical
position. The support has portions which confine the container
against lateral movement and portions which rest on the lid when
the support is in the horizontal position so as to prevent access
to the container by dogs and the like.
[0005] U.S. Pat. No. 4,199,161 to Nieminen et al. discloses a trash
cart for storing garbage bags comprising an open-top container
having a bottom and continuous substantially vertical side wall
having a top edge and a hollow domed cover having an
inwardly-turned rim, the inner edge of the rim extending to the top
edge of the side wall, the cover overhanging the container by
substantially to the extent of the rim whereby, when the cover is
closed on the container, the cart has the appearance of a large
mushroom or toadstool. The cover has an opening to receive the
handle in a manner to prevent opening of the cover by animals, and
is hinged to the container and a brace for the hinge forming a
compartment in the cover for extra empty garbage bags. The
container has a capacity to store a plurality of filled garbage
bags and the domed cover is capable of storing at least one full
garbage bag.
[0006] U.S. Pat. No. 5,044,114 to Terbrusch et al. discloses a
trash container with a tightly secured cover in which a first
engaging structure disposed on the outer surface about an open top
of a pail interlocks with a second engaging structure disposed on
the inner surface of a depending skirt of the cover to tightly
secure the cover to the open top of the pail so that it will
prevent an animal from entering through the open top and eat the
trash therein.
[0007] U.S. Pat. No. 5,385,258 to Sutherlin discloses an animal
tamper-resistant trash container and method of constructing such a
trash container utilizing a conventional trash container having a
bottom, side wall and an open upper end and removable lid
therefore. The improvement included a first and second annular band
or ring each clampably connectable around the lid and container
adjacent its opening, respectively. A hinge is formed between the
first and second bands whereby the lid is permanently pivotally
attached to the open upper end of the container. A unique latch
which automatically engages when the lid falls to a closed position
is virtually unopenable by large wild animals such as a raccoons,
foxes, opossums, dogs and the like.
[0008] In addition to the containers described in these patents,
homeowners have resorted to other homemade solutions to prevent the
tipping of refuse container and/or the removal of the lids by
animals. One such homemade solution involves placing bricks, cinder
blocks or other heavy objects on top of the lid to prevent animals
from lifting the lids. Another homemade solution to keep the
animals out of conventional trash cans is to strap bungee cords
over the lids and attach the hooks of the bungee cords to the
handles or the sides of the container. The bungee cords strap down
the lid of the container, but may slide off the top of the lid and
down around the sides and, because the bungee cords use hooks on
both ends, the bungee cords can become completely detached from the
container when the lid is removed and may be lost once they are
separated from the container.

[0023] Referring initially to FIG. 1, an animal-resistant refuse
container 100 in accordance with the invention is illustrated as
including a container body 102 having a pair of container handles
104 mounted to and/or extending there from, and a lid 106 disposed
on an open upper end of the container body 102 to close the refuse
container 100. In the illustrated embodiment, the container body
102 is generally cylindrical in shape with a central cavity, and is
defined generally by upwardly-extending cylindrical side walls 108
having a top edge 110 (FIG. 2) defining an opening at the top end.
The lid 106 is shaped to correspond to the shape of the open end of
the container body 102, such as circular in top plan view in the
illustrated embodiment, and has a generally domed top surface 112
that merges into a downturned peripheral flange 114. The lid 106
may further include an elongated lid handle 116 extending upwardly
from the domed top surface 112 along a diametric line across the
lid 106 such that the lid handle 116 may be oriented and aligned
between the container handles 104. At either end of the lid handle
116, the lid 106 may include anchor members, such as upwardly
extending tabs 118, for attaching latching mechanisms 120 between
the lid 106 and the corresponding container handles 104. The tabs
118 may have slots 122 therethrough such that one end of a latching
mechanism 120 may be connected to the lid 106 at the tab 118 and
the other end of the latching mechanism 120 may be connected to the
corresponding handle 104 to secure the lid 106 to the container
body 102 in a manner described more fully below.
[0024] Referring to FIGS. 2 and 3, a first embodiment of a latching
mechanism 120 in accordance with the invention is illustrated
engaging a tab 118 and a handle 104 to secure the lid 106 to the
container body 102. In this embodiment, the latching mechanism 120
is configured so that one end of the latching mechanism 120 may be
permanently or semi-permanently attached to the tab 118, and the
other end of the latching mechanism 120 may be readily attach to
the handle 104 to secure the lid 106 to the container body 102 and
to detach from the handle 104 to allow the lid 106 to be removed
from the container body 102. At a first end of the latching
mechanism 120, a lid connector 130 configured to be connected to
the tab 118 by threading a bolt 132 or other fastener through
openings in the lid connector 130 and through the slot 122 of the
tab 118. The bolt 132 may connect the latching mechanism 120 to the
lid 106 in a semi-permanent manner such that tools may be used to
remove the latching mechanism 120 from the lid 106 for maintenance
purposes or to attach the latching mechanism 120 to a different lid
106 of a different refuse container 100. Alternatively, the lid
connector 130 may be more permanently connected to the lid 106 via
a rivet or other similar fastener preventing the latching mechanism
120 from being easily detached from the lid 106. As a further
alternative, the lid connector 130 may include a safety snap hook
or similar fastener that may retentively engage the tab 118 while
allowing the latching mechanism 120 to be removed from the lid 106
by manipulation without the need for tools.
[0025] The lid connector 130 may be connected to an oppositely
disposed container body connector, such as handle connector 134, by
an elastomeric member 136. The elastomeric member 136 may be
fabricated from any resilient material, such as rubber, plastic,
natural rubber, silicone, or other elastic or visco-elastic
material, and is securely attached the lid connector 130 and handle
connector 134 so that a force may be exerted to pull the connectors
130, 134 apart when locking the lid 106 to the handle 104, and the
elastomeric member 136 may stretch under the force to allow the
connectors 130, 134 to separate, without the elastomeric member 136
detaching from either of the connectors 130, 134. In addition to
the portion connecting to the elastomeric member 136, the handle
connector 134 includes a hook 138 and an outwardly extending grip
140. The hook 138 may extend outwardly on the handle connector 134
away from the connection to the elastomeric member 136, and may be
configured to fit over and enclose the handle 104 in a manner that
secures the hook 138 to the handle 104 under the force exerted by
the tension in the elastomeric member 136. Configured in this way,
the handle connector 134 is pulled away from the lid connector 130
a sufficient distance so that tip of the hook 138 is past the
handle 104 allowing the hook 138 to be disposed around the handle
104 as the force of the elastomeric member 136 pulls the handle
connector 134 toward the lid connector 130. To facilitate
attachment to and removal from the handle 104 of the hook 138, the
latching mechanism 120 may include a grip 140 configured to be
grasped by a user. The grip 140 may extend outwardly away from the
hook 138 so that the grip 140 may be grasped by a user of the
refuse container 100 to manipulate the latching mechanism 120 when
the hook 138 engages the handle 104. Further, the grip 140 may be
configured to provide sufficient clearance to be grasped when the
user is wearing gloves, such as during cold whether or when the
user is a trash collector.
[0026] In the illustrated embodiment, the latching mechanism 120 is
attached to the handle 104 to secure the lid 106 to the container
body 102. To remove the latching mechanism 120, a user grasps the
grip 140 and pulls outwardly in the direction of the arrows of
FIGS. 2 and 3. Once the tip of the hook 138 is past the outer edge
of the handle 104, the latching mechanism 120 is pulled upwardly
slightly until the tip of the hook 138 has sufficient clearance
from the handle 104 to that the hook 138 will not recapture the
handle 104. The force of the user is lessened to allow the handle
connector 134 to move inwardly toward the lid handle 116 under the
biasing force of the elastomeric member 136, with the hook 138
moving past the handle 104.
[0027] While the lid connector 130, handle connector 134 and
elastomeric member 136 are discussed above as being distinct
components of the latching mechanism 120, those skilled in the art
will understand that two or more of these components may be
fabricated from a unitary piece of material. For example, in one
embodiment, the connectors 130, 134 and elastomeric member 136 may
be fabricated from a single unitary piece of elastomeric material
such that separate attachment of the connectors 130, 134 to the
elastomeric member 136 is not required. As a further alternative,
the lid connector 130 and elastomeric member 136 may be fabricated
from a single unitary piece of elastomeric material, with the
handle connector 134 be fabricated from a relatively more rigid
material, such as wood, aluminum, steel and the like, and attached
to the free end of the elastomeric member 136 as described above.
Still further, the hook 138 and grip 140 may be fabricated
separately as a single component separate from the handle connector
134 from injection molded plastic or other material. The hook 138
and grip 140 may then be rigidly connected to the handle connector
134, or rotatably connected to the handle connector 134 and secured
in position by a set screw (not shown). In the latter
configuration, the set crew may be loosened to allow the hook 138
and grip 140 rotated between the illustrated position and a
shipping position, such as through a 180.degree. rotation from the
illustrated position, that may facilitate stacking of the lids 106
during shipping. Other configurations of the components of the
latching mechanisms 120 components are anticipated and are
contemplated by the inventors as having use in a refuse container
in accordance with the present disclosure.
[0028] In the illustrated embodiment, the handles 104 are pivotally
mounted on the sides 108 of the container body 102, and engage the
lid 106 to secure the lid 106 to the container body 102. Referring
to FIG. 4, the lid 106 is configured to be engaged and retained by
the handles 104, and includes an annular groove 144 midway down the
vertical width of the peripheral flange 114 and extending the
circumferential extent of flange 114. On each side of the container
body 102, a handle support buttress 146 extends outward from the
plane of the corresponding side 108, and is of generally elongate
rectangular configuration. An inward step 148 extends along an
upward longitudinal side of the support buttress 146 and intersects
with the cylindrical sides 108 of the container body 102. Situated
along the support buttress 146 is a mounting boss 150 of elongate
rectangular construction. The mounting boss 150 is hollow and
includes a pair of assembly apertures 152 situated in opposite ends
thereof. Disposed adjacent to the opposite ends of the mounting
boss 150 are vertical tracks 154 which are recessed within the
sides 108 of the container body 102. Each of the tracks 154 is of
an upright rectangular shape, the size of which being prescribed in
greater detail below.
[0029] Each of the handles 104 (one of which is shown) is of a
generally U-shaped configuration. Each handle 104 comprises a bight
portion 156 from which elongate arm segments 158, 160 extend. The
arm segments 158, 160 adjoin the bight portion 156 of each handle
by way of intermediate segments 162, 164, respectively. The
intermediate segments 162, 164 are offset from the plane of the
remote arm segments 158, 160 such that the bight portion 156 of
each handle 104 lies in a plane outward of the plane of segments
158, 160. The purpose for the offset of bight portion 156 is to
enable the user of the waste container to conveniently grasp the
portion 156 as a handle in transporting the container from one
location to another. It will be appreciated from FIG. 4 that the
segments 158, 160, 162, 164, and bight portion 156 are of generally
tubular plastic construction, with each segment being of relatively
large diameter. As a result, bight portion 156 is of full grip
diameter for the comfort of the user as a handle.
[0030] Situated at distal ends of the arm segments 158, 160 are
camming lobe projections 166. Each camming lobe projection 166 is
of a triangular side-profiled shape, with a remote planar side 168
of each lobe projection 166 facing the container body 102 in
general alignment with the vertical tracks 154 formed therein. It
will be appreciated that the remote side 168 of each camming lobe
166 is flat and extends generally in a vertical direction. A lid
locking tooth projection 170 is likewise provided integral with
each arm segment 158, 160 and is of a general triangular shape
generally similar to the camming lobe projections 166. Each tooth
projection 170 is spaced apart from its corresponding lobe
projection 166, and extends parallel thereto. Further, each tooth
projection 170 provides an inwardmost flat surface 172 extending
parallel with lobe surface 168 which rotates with the handle into a
horizontal orientation in a manner described below. As seen from
FIG. 4, proximate to the distal end of each arm segment 158, 160 of
the handles 104 is an inward directed stud projection 174 of
cylindrical shape. The projection 174 has a retention flange 176
which extends in an annular direction partially around each stud
projection 174 and is spaced a distance from the arm segments 158,
160.
[0031] The lid 106 fits over the top edge 110 of the container body
102 until the downward edge of the peripheral flange 144 of the lid
106 rests upon the step portion 148 of the container body 102.
Since the lid 106 and container body 102 are both of circular cross
section, the lid 106 can be oriented upon the container body 102 in
any orientation throughout a 360 degree range. When used with the
latching mechanism 120, however, the lid 106 is oriented with the
tabs 118 proximate the handles 104. Each of the handles 104 is
secured to the handle mounting boss 150 of the container body 102
by insertion of the pivot stud projections 174 of the handle
through the apertures 152 in opposite ends of the mounting boss
150. As a stud projection 174 penetrates through the aperture 152,
the annular retention flange 176, which tapers outwards, engages
against an internal side of the end mounting boss 150 to retain the
handle 106 in a pivotal relationship to the mounting boss 150.
[0032] FIGS. 5 and 6 show the lid locking handles 104 assembled to
the container body 102, and illustrate in sequence the operation of
the handles 104 in securing the lid 106. With reference to FIG. 5,
the handle 104 is pivoted away from the container body 102 so as to
enable the lid 106 to slide over the top of the container body 102.
The surfaces 168 of camming lobe projections 166 of the handle 104
at this point approach parallel with the recesses of the vertical
tracks 154 within the container body 102. Subsequent to the
positioning of the lid 106 upon the container body 102, seated
against the horizontal step 148 thereof, the lid locking handles
104 can be pivoted upward into an upright position as illustrated
in FIG. 6. During the pivotal upward movement of the handles 104,
the radiused lobe projections 166 impress against the vertical
tracks 154 as the tooth projections 170 of the handles 104 protrude
into the annular groove 144 of the lid 106. In the upright locked
position illustrated in FIG. 6, the elongate camming lobe
projection 166 has deformed the resilient waste container body 102
inward at the track recesses 154 such that latent resilient forces
within the elastomeric container body 102 exert an outward force
against each lobe projection 166. This residual elastomeric force
frictionally secures the camming lobe projections 166 into the
horizontal orientation depicted in FIG. 5, and resists any
inadvertent or unintended pivotal movement of the handle 104 out of
its locking relationship with the lid 106, thereby providing a
first level of security to prevent animals from removing the lid
106 and accessing the interior of the container body 102. Release
of the handle 104 can be achieved by manual pivotal movement of the
handle 104 away from the lid 106, overcoming the frictional lock
between the container body 102 and the camming projections 166.
[0033] As described previously, the container body 102 and lid 106
are of circular cross sectional shape, whereby the lid 106 can be
situated upon the container body 102 in any position within a 360
degree range. It will be noted that the locking handles 104
effectively function to lock the lid 106 to the container body 102
regardless of the orientation of the lid 106 throughout its 360
degree range of operation. However, in order to attach the latching
mechanisms 140 and further secure the lid 106 to the container body
102, the lid 106 will be oriented with the tabs 118 of the lid 106
proximate the handles 104. In other alternative embodiments, the
container body 102 and the lid 106 may have other cross-sectional
shapes than the circular cross-sectional shape of the illustrated
embodiment, such as square, rectangular, triangular, ovoid and the
like, so that the lid 106 mates with the top of the container body
102 and tabs 110 on the lid 106 can be disposed proximate the
handles 104 of the container body 102 for attaching the latching
mechanisms 120. Additionally, the refuse container 100 may be
provided with more than two handles 104 and corresponding tabs 110
as necessary to provide a desired level of attachment and
security.
[0034] With reference to FIG. 1, it will be noted that the bight
portion 156 of the locking handles 104 extends upward from the lid
106 in prominent fashion. The separation of the handle 104 from the
lid 106 facilitates attachment of the hook 138 to the handle 104 as
described above. Further, because of the offset between the bight
portion 156, the arm segments 158, 160, and intermediate segments
158, 164, the bight portion 156 can operate as a handle for
transporting the refuse container 100. Moreover, because dual
handles 104 are provided on opposite sides of the container, the
bight portions 156 can be used for lifting the refuse container 100
upward without disturbing the lid lock. Additional description of
the lid locking handles and an associate trash container can be
found in U.S. Pat. No. 6,691,840, entitled "Lid Locking Handle for
Waste Container," the entire disclosure of which is incorporated
herein by reference. However, while the container body 102 is
illustrated and described herein as having pivoting handles 104
locking the lid in place, those skilled in the art will appreciate
that the refuse container 100 having latching mechanisms 120 may be
implemented with handles that are fixedly attached to the sides 108
of the container body 102 and/or that do not engage the lid 106 to
lock the lid 106 in place, but with the latching mechanisms 120
still securing the lid 106 to the container body 102.
[0035] The refuse container 100 described above was tested with and
without the latching mechanisms 120 securing the lid 106 to the
container body 102. The tests involve placing the refuse container
100 among four captive raccoons weighing up to 15 pound each and
observing the raccoons' attempts to access the refuse container
100. The raccoons involved in the testing are regularly challenged
by their keepers by providing refuse containers to open for
exercise and behavior management. The success of each test was
measured by the amount of time necessary for the raccoons to open
the refuse container, with the test being deemed successful if the
refuse container remained unopened after 30 minutes. In the first
test, an empty refuse container 100 was placed upright with the
handles 104 locking the lid 106 in place without the latching
mechanisms 120. The engagement of the open end of the container
body 102 by the annular groove 144 of the lid 106 substantially
limited the raccoons' ability to pull at and damage the lid 106.
The raccoons lost interest after 15 minutes, and the raccoons did
not have much activity investigating or attempting to unlock the
handles 104 thereafter.
[0036] In a second test, the refuse container 100 was filled with
48 pounds of weight to keep the container 100 upright and to
simulate being filled with garbage, and was placed upright with the
handles 104 locking the lid 106 in place without the latching
mechanism 140. After approximately 15 minutes, one of the handles
104 was unlocked when one of the raccoons attempted to pull itself
onto the top of the refuse container 100. However, the raccoons
were unable to tip the refuse container 100 over, and the raccoons
failed to remove the lid 106 within 30 minutes. The test was
extended after 30 minutes by placing the refuse container 100 on
its side with one of the handles 104 unlatched. Once the refuse
container 100 was tipped and unlocked, the raccoons were able to
pull the lid 106 of the container body 102 within approximately 30
to 60 seconds, and gain access to the interior of the refuse
container 100.
[0037] As a final test, latching mechanisms 140 as described above
locked the handles 104 in the upright engaged position and secured
the lid 106 to the container body 102. In the latching mechanisms
140 used in this test, the elastomeric member 136 was fabricated
from rubber. The refuse container 100 was filled with 35 pounds of
weight to simulate the container 100 being at least partially
filled with garbage. When the locked refuse container 100 was
exposed to the raccoons, the raccoons chewed and tugged at the
rubber elastomeric member 136, but could not break the member 136.
The raccoons did not attempt to unhook the latching mechanisms 120
and ultimately could not unlock the handles 104 and gain access
into the refuse container 100. After a relatively short period of
time, and in significantly less time than the 30 minute time limit,
the raccoons lost interest and ceased attempting to open the locked
refuse container 100.
[0038] FIGS. 7 and 8 illustrate an alternate embodiment of a
latching mechanism 180 utilizing a standard swivel eye piston snap
182 of the type known to those skilled in the art and commonly used
to attach a dog leash to a dog collar or to attach a shoulder strap
to purse, computer bag, duffle bag, or a garment bag, among other
applications. In this embodiment, the latching mechanism 180 may be
attached to the handle 104 by a clamp 184 encircling the handle 104
and fastened to a connector 186 of the snap hook 182 by a rivet
188. Alternatively, the clamp 184 may be attached to the connector
186 by a less permanent fastener, such as the bolt 132 used in the
latching mechanism 120 discussed above. As is commonly known to
those in the art, the snap hook 182 includes a body 190 having one
end pivotally attached to the connector 186 to allow the body 190
to swivel. The opposite end of the body 190 defines a hook 192
having an opening on one side. The snap hook 182 further includes a
piston 194 slidably disposed in the body 190 and biased outwardly
from the body 190 by an internal spring (not shown) toward the tip
of the hook 192 to enclose the interior of the hook 192 and retain
articles disposed therein, such as dog collars, corresponding
portions of fasteners and the like. The piston 194 includes a
button 196 disposed outwardly of the body 190 of the snap hook 182
and engageable to slide the piston 194 inwardly into the body 190
such that a retained article may be removed through the opening of
the hook 192.
[0039] Once the lid 106 is placed on the container body 102 and, if
necessary, the tabs 118 are aligned proximate the handles 104, the
snap hook 182 is attached to the tab 118 by retracting the piston
194 and passing the tip of the hook 192 through the slot 122 of the
tab 118. When the button 196 of the piston 194 is released, the
piston 194 closes the opening of the hook 192 to maintain
attachment to the tab 118. Depending on the configuration of the
latching mechanism 180, it may be necessary to apply sufficient
force to cause the handle 104 to deflect slightly to allow the tip
of the hook 192 to reach the slot 122 of the tab 118.
Alternatively, the dimensions of tab 118, the clamp 184 and the
snap hook 182 may be such that the tip of the hook 192 reaches the
slot 122 without deflecting the handle 104. Still further, the
clamp 184 may be configured so that the handle 104 may be slidable
therein so that the tip of the hook 192 may reach the slot 122 of
the tab 118. In order to open the refuse container 100, the snap
hook 182 may be detached from the tab 118 by engaging the button
196 to retract the piston 194 and expose the opening of the hook
192.
[0040] It will also be appreciated that this embodiment of the
latching mechanism 180 allows the refuse container 100 to be opened
while maintaining attachment of the lid 106 to the container body
102. Each of the latching mechanisms 180 except one may be detached
from the lid 106, thereby allowing the lid 106 to be removed from
the container body 102 while the lid 106 remains tethered to the
handle 104 of the container body 102 by the remaining latching
mechanism 180. Those skilled in the art will understand that other
connection mechanisms and configurations of the latching mechanism
180 are possible and contemplated by the inventors wherein both the
handle 104 and the lid 106 are retentively engaged by the latching
mechanism 180 such that the lid 106 may be secured to the container
body 102 by one of the latching mechanisms 180 when the lid 106 is
opened.
[0041] The embodiments shown and discussed herein are illustrative
of refuse containers 100 and latching mechanisms 120, 180 in
accordance with the invention. Additional configurations of refuse
containers and latching mechanisms in accordance with the invention
are contemplated by the inventors. For example, the container body
102 may include additional handles 104 spaced about the sides 108
and/or the lid 106 may include additional anchor members or tabs
118 for connecting the latching mechanisms to the handles 104.
Moreover, the anchor members or tabs 118 may extend outwardly from
other positions on the top surface 112 of the lid 106, and need not
extend from the lid handle 116. Configured in this manner,
additional latching mechanisms may be used to secure the lid 106,
or it may be possible to secure the lid 106 in more than the two
alternate positions shown herein with the lid handle 116 aligned
between the container handles 104. Alternatively, the slots 122 may
be provided in the lid handle 116 itself to eliminate the need for
forming additional anchor members or tabs 118 on the top surface
112 of the lid 106. In other embodiments, the portion of the
container body 102 engaged by the latching mechanism 120 may not be
a handle of the container body 102. Any other container body
attachment projection from the sides 108 of the container body 102
that is engageable by the latching mechanisms 120, 180 to secure
the lid 106, such as outwardly extending bosses, hooks and the
like, and the handles 106 need not be pivotable and/or lid locking
as described therein so long as the lid 106 is secured to the
container body 102 when the latching mechanisms are attached.
[0042] While the preceding text sets forth a detailed description
of numerous different embodiments of the invention, it should be
understood that the legal scope of the invention is defined by the
words of the claims set forth at the end of this patent. The
detailed description is to be construed as exemplary only and does
not describe every possible embodiment of the invention since
describing every possible embodiment would be impractical, if not
impossible. Numerous alternative embodiments could be implemented,
using either current technology or technology developed after the
filing date of this patent, which would still fall within the scope
of the claims defining the invention.
