TECHNICAL FIELD
This disclosure relates generally to tubs, and more specifically to tamper evident tubs and containers.
BACKGROUND
There are many tubs and containers in use today with many different types of lids. Further, many household items such as laundry detergent pods, dish soap, food products, etc., require a container and lid that is secure enough to prevent a child from opening the same. Further, it is increasingly important for the integrity of items stored inside a container to be protected. For example, it should be evident if a container has been opened or a seal has been broken for the first time. However, many lid/container combinations that prevent children from opening these containers and are tamper evident are also unnecessarily cumbersome for adults to open. Therefore, there exists a long-felt but unresolved need for a tamper evident and child proof container with a lid that is also not overly cumbersome for adults to open and provides an indication of the integrity of the items contained therein.
BRIEF SUMMARY OF THE DISCLOSURE
Briefly described and according to one embodiment, aspects of the present disclosure generally relate to tubs, and more specifically tamper evident tubs and containers.

In particular embodiments, the tub is manufactured from a metal or composite material.
Turning now to exemplary tubs illustrated in the figures, FIG. 1 depicts a perspective view of an exemplary tub 100 with a lid 112 in a closed position, according to one embodiment of the present disclosure. In the embodiment shown in FIG. 1, the exemplary tub 100 includes a tub body 102 with a first side 104, second 106, bottom 108, top 110, and the lid 112. According to the present embodiment, the exemplary tub 100 has a substantially rectangular shape with rounded edges. In one embodiment, the top of the lid 112 is flat and the edges of the lid may slope downward in a convex manner. As will be discussed and shown later in the description of FIG. 2, the lid 112 encloses and seals the interior of the tub 100.
In various embodiments, the exemplary tub 100 includes various features proximate the top 110 of the exemplary tub 100. In one embodiment, the exemplary tub 100 includes a satellite ring 114. According to various aspects of the present disclosure, the satellite ring 114 is a protruding ridge that extends outward from the tub body 102. According to one embodiment, the satellite ring 114 has a flat upper surface and round lower surface. In some embodiments, the satellite ring 114 has a round upper surface (convex) and an inwardly round bottom surface (concave), whereby one satellite ring 114 may accept a satellite ring of a separate tub in a stacked configuration (e.g., if the lids are in an open position). In particular embodiments, the satellite ring 114 extends fully or partially around the body 102 of the exemplary tub 100. According to various aspects of the present disclosure, the satellite ring 114 may provide a surface or location for the lid 112 to meet and seal when in a closed position. In various embodiments, the satellite ring 114 acts as a base or starting point from which other tub features extend.
In one embodiment, the satellite ring 114 extends downward at location 116 in order to partially form or integrate with the latch assembly 118. In some embodiments, the latch assembly 118 is entirely separate from the satellite ring 114. In certain embodiments, the latch assembly 118 begins to linearly and gradually increase in width at starting at the location 116. In some embodiments, the linear increase in width of the latch assembly 118 forms about a 45 degree downward angle between the satellite ring 114 and the location 116. In various embodiments, the latch assembly 118 extends about 1.5 inches (3.81 cm) downward from the satellite ring 114. According to various aspects of the present disclosure, the latch assembly 118 extends downward in order to provide a surface to include one or more breakable tabs 120. In various embodiments, the one or more breakable tabs 120 are removable portions of the latch assembly 118. The breakable tabs 120 may be connected to the latch assembly 118 by means of perforated seams, fused corners, or other appropriate means of attachment, and may operate similarly to typical tear strips. In various embodiments, and as will be discussed later in description of FIG. 7, the one or more breakable tabs 120 may be removed to reveal additional features of the exemplary tub 100.
Continuing with FIG. 1, a gap 122 may be located between the upper portion of the one or more breakable tabs 120 and the upper portion of the latch assembly 118. In various embodiments, the gap 122 may allow for a user or handler of the exemplary tub 100 to achieve better leverage to pull away the breakable tab 120. As will be described in greater detail in the discussion of FIG. 2, additional exemplary tub 100 features may be visible through the gap 122.
Proceeding now to FIG. 2, the exemplary tub 100 is shown with the lid 112 in an open position prior to being closed, according to one embodiment of the present disclosure. According to various aspects of the present disclosure, the exemplary tub 100 may be manufactured and distributed with the lid 112 in an open position. In particular embodiments, manufacturing the exemplary tub 100 with the lid 112 in an open position may allow for a user to later fill the exemplary tub 100 with various materials or objects, and then close the lid 112, thereby securing the lid 112 in a closed position. In the present embodiment, the lid 112 is positioned behind the exemplary tub 100 and is facing upward. In various embodiments, the lid 112 includes one or more lift tabs 202. According to various aspects of the present disclosure, while transitioning from an opened position to a closed position, the lift tabs 202 included on the lid 112 may align with and enter the lift tab holes 204.
In particular embodiments, the latch assembly 118 includes an upper surface 119. In various embodiments, the satellite ring 114 may be integrally formed with the latch assembly 118. In certain embodiments, the upper surface 119 is wider than the other portion(s) of the satellite ring 114 in order to include the lift tab holes 204. As will be described in greater detail in the discussion of FIG. 7, the lift tab holes 204 allow for the lift tabs 202 to enter an area behind the breakable tabs 120.
Continuing with FIG. 2, the tub interior 210 is shown, according to one embodiment of the present disclosure. In various embodiments, the tub interior 210 may be operable to store objects and elements ranging from household cleaning supplies, liquids, chemicals, etc. In a particular embodiment, the lid 112 includes a plurality of lid support ribs 206. According to various aspects of the present disclosure, the plurality of lid support ribs 206 are located along the inner curved portion 112A of the lid 112. In certain embodiments, the lid support ribs 206 may be molded onto the curved portion 112A of the lid 112 during the manufacturing process. As mentioned briefly above, the lid 112 may transition from an opened position to a closed position. In one embodiment, while transitioning from an open position to a closed position, the lid support ribs 206 may accept an upper rim 208 of the exemplary tub 100 at the rib location 206A. As shown in the present embodiment, the rib location 206A is a substantially flat portion of the lid support rib 206. In a closed position, each rib location 206A of the plurality of support ribs 206 may accept the tub upper rim 208. According to various aspects of the present disclosure, the plurality of support ribs 206 may include rounded ends 206B. In one embodiment, the rounded ends 206B may extend past the tub upper rim 208 and into the tub interior 210 when in a closed position. In certain embodiments, where the tub interior 210 is filled near the tub upper rim 208, the lid 112 may not close entirely if the elements stored within the tub interior 210 prevent the rounded edges 206B of the plurality of support rubs 206 from extending downward into the tub interior 210.
Turning now to FIG. 3, a rear view of the exemplary tub 100 is shown according to one embodiment of the present disclosure. In various embodiments, the lid 112 is attached to the tub body 102 by one or more hinges 302. As shown in the present embodiment, two hinges 302 attach the tub lid 112 to the satellite ring 114. In one embodiment, the upper portion of the hinge 302 is integrally attached to the lid 112, and the lower portion of the hinge 302 is integrally attached to the tub body 102. In particular embodiments, the satellite ring 114 may not be included in attaching the lid 112 to the tub body 102 by one or more hinges 302. For example and according to one embodiment, the satellite ring 114 may discontinue circumscribing the tub body 102 in near proximity to the one or more hinges 302. In this example, the one or more hinges 302 may directly attach the lid 112 and the tub body 102 without integrally forming with the satellite ring 114. In one embodiment, a hinge support 304 is included in near proximity to each hinge 302. In the present embodiment, the hinge supports 304 are located below the hinges 302. In various embodiments, the hinge supports 304 are oriented perpendicular to the each hinge 302 and also provide structural support to the hinge 302. In particular embodiments, the hinge supports 304 are integrally formed with the one or more hinges 302 to form one unitary piece. In other embodiments, the hinge supports 304 are integrally formed onto the tub body 102 and one side portion of the hinge supports 304 are integrally formed onto the lower portion of the satellite ring 114.
Continuing with the description of FIG. 3, at location 306, the lid 112 can be seen positioned with a bottom surface in contact, and creating a seal with, the satellite ring 114. In this position, the lid 112 and satellite ring 114 create a flush outer surface at and along the location 306 where it continues around the tub body 102. Additionally, in the present embodiment, both the lid 112 and satellite ring 114 are shown protruding outward from the tub body 102, similar to an umbrella shape. In various embodiments, the container body 102 may taper in dimensions, beginning at the satellite ring 114 and continuing downward towards the tub bottom 108 (e.g., the circumference of the tub 100 at the top 110 is greater than the circumference of the bottom 108). In certain embodiments, the tapered shape of the exemplary tub 100 may allow for the tub 100 to be stacked or placed into another separate tub for storage, transportation, etc.
Turning now to FIG. 4, a top view of the exemplary tub 100 is shown, according to one embodiment of the present disclosure. In the present embodiment, the tub interior 210 is shown. In one embodiment, the tub bottom 108 includes a dimple 402. In various embodiments, the dimple 402 is a spherical indentation that may protrude upward into the tub interior 210, thereby slightly reducing the volume of the tub interior 210.
Continuing with FIG. 4, the lift tab holes 204 are shown from an upper perspective, according to one embodiment of the present disclosure. As can be seen in this view, in the embodiment shown, the exemplary tub 100 includes a latch 404 as well as one or more latch support ribs 406. As will be described in further detail during the discussion of FIG. 6, the latch 404 may include an inwardly extending portion of the latch assembly 118 that secures a lift tab 202, thereby maintaining the lid 112 in a closed position when closed. In particular embodiments, the latch support ribs 406 protect the integrity of the latch 404.
The hinges 302 are shown connecting the lid 112 with the rest of the exemplary tub 100. In the present embodiment, the exemplary tub 100 includes two hinges 302. In various embodiments, the exemplary tub 100 may be manufactured (e.g., molded, 3D printed, etc.) to integrally include the one or more hinges 302. In particular embodiments, the lid 112 and the tub body 102 may be manufactured individually and may be joined or fused at the one or more hinges 302. In other embodiments, the exemplary container 100 includes more or less hinges 302 than shown, depending on certain design configurations and constraints. In one embodiment, the exemplary tub 100 is manufactured as one unitary member.
Turning now to FIG. 5, a side view of the exemplary tub 100 is shown according to one embodiment of the present disclosure. In the present embodiment, the hinge 302 is shown protruding outward slightly beyond where the lid 112 meets the satellite ring 114. Also shown in the present embodiment is the hinge support 304. In one embodiment, the hinge support 304 may be molded to or otherwise attached to both the hinge 302 and the tub body 102. In various embodiments, the hinge support 304 may extend downward along the tub body 102 about 1.0 inches (2.54 cm) from the bottom of the hinge 302. In particular embodiments, the attachment of the hinge support 304 to both the hinge 302 and the tub body 102 provides structural support to the hinge 302 as well as the lid 112.
As will be described in greater detail below, FIGS. 6, 7, and 8, show cross sectional views taken through the lid 112 and latch assembly 118 (indicated by the dashed line A-A in FIG. 1), according to various aspects of the present disclosure. In various embodiments, the cross sectional views show how the lift tab 202 (and individual portions thereof) engages with the latch assembly 118 (and individual portions thereof) throughout the transition of opening and closing the lid 112.
FIG. 6 shows a cross section taken through the latch assembly 118 and a breakable tab 120 of the exemplary tub 100 with the lid 112 in a closed position. In the present embodiment, the cross section reveals a lift tab chamber 602 with a lift tab 202 occupying the space therein. In this embodiment, the lift tab 202 is shown in a latched position within the lift tab chamber 602. In one embodiment, the lift tab 202 includes a latch tooth 604. According to various aspects of the present disclosure, the latch tooth 604 may have a substantially triangular shape. As seen in the present embodiment, the latch tooth 604 resembles a right-angled triangle. In other embodiments, the latch tooth 604 may be any outwardly extending ridge of the lift tab 202 and may resemble any shape that allows for one directional movement when engaged with another object (e.g., a hook). In a particular embodiment, the object the latch tooth 604 is engaged with is the latch 404. In various embodiments, the angled side of the latch tooth 604 may allow for the latch tooth 604 to pass over the latch 404. In one embodiment, once the acute-angled side of the latch tooth 604 has passed over the latch 604, the right-angled side of the latch tooth 604 may prevent the latch tooth 604, and thus the lift tab 202, from retreating backward. For example, and for the purpose of understanding, the latch tooth 604 and latch 404 may behave similarly to a latch bolt on a door. Generally, the latch bolt on a door is angled and allows for the door to be easily closed; however, once the door is closed it will not reopen by simply pulling the door back outward.
In one embodiment, the lift tab 202 includes a downwardly-extending portion below the latch tooth 604. According to various aspects of the present disclosure, included on the downwardly-extending portion of the lift tab 202 are one or more press ridges 606. In the present embodiment, three press ridges 606 are shown as rounded protrusions protruding from the lift tab 202. As will be discussed in greater detail during the description of FIG. 7, a user may inwardly (towards the tub body), and then upwardly (out of the lift tab chamber), push the lift tab 202 via the press ridges 606 in order to unlatch or release the lift tab 202 from the closed position within the lift tab chamber 602. In one embodiment, the press ridges 606 may allow a user to better grip the region of the lift tab 202 for a user to press. In some embodiments, the lift tab 202 may include more or less press ridges 606 as shown (e.g., two press ridges, one press ridge, many press ridges, no press ridges, etc.).
In one embodiment, a lift tab chamber wall 608 is seen behind the lift tab 202. According to various aspects of the present disclosure, at least two lift tab chamber walls 608 define the space of the lift tab chamber 602. In particular embodiments, the lift tab chamber walls 608 are substantially perpendicularly aligned with the tub body 102, thereby defining a space outward from the tub body 102. In one embodiment, the lift tab chamber walls 608 extend downward from the upper surface 119 of the latch assembly 118 to below the lowest portion of the lift tab 202. In various embodiments, the lift tab chamber walls 608 extend below the lowest portion of the lift tab 202 to prevent access to the lift tab 202 while the breakable tab 120 is still attached to the latch assembly 118. In certain embodiments, the lift tab chamber walls 608 may be integrally formed with the latch assembly 118 and the tub body 102. In other embodiments, only one side of the lift tab chamber walls 608 are integrally formed or connected to an adjacent portion of the exemplary tub 100. In various embodiments, the lift tab chamber walls 608 not only define the space of the lift tab chambers 602, but also provide structural support to the latch assembly 118. In certain embodiments, the lift tab chamber walls 608 may be triangular shaped, rectangular shaped, quadrant shaped, etc.
Continuing with FIG. 6, a cross section of the breakable tab 120 is shown, according to one embodiment of the present disclosure. In one embodiment, the breakable tab 120 is positioned slightly below the latch 404, thus creating the gap 122 seen from the front of the exemplary tub 100 in FIG. 1. The gap 122 between the breakable tab 120 and the latch 404 may allow for a user or handler of the exemplary tub 100 to see the latch tooth 604 but not access the press ridges 606. In some embodiments, the breakable tab 120 may be flush with the latch 404, (or any portion of the latch assembly 118) thereby eliminating the presence of the gap 122. In particular embodiments, the breakable tab 120 may prevent children, or any user with under-developed dexterity skills, from opening the exemplary tub 100 until the breakable tab 120 is removed. In certain embodiments, even when a breakable tab 120 is removed and the lift tab 202 is exposed, a user with under-developed dexterity skills may still struggle to open the lid 112.
In the present embodiment, and located immediately above the cross section of the latch 404 is a cross section of a latch support rib 406. In particular embodiments, the latch support rib 406 has a substantially triangular shape and is attached to or integrally formed with the latch 404 as well as the latch assembly 118. In other embodiments, the latch support rib 406 may have rectangular shape, a quadrant shape, etc. As described previously in the discussion of FIG. 4, the latch support rib 406 provides structural support to the latch 404. For example, a scenario may arise where an upward force is being exerted on the lid 112 in an attempt to open the exemplary tub 100. In this scenario, the latch support rib 406 may distribute the force between the latch 404 and the latch assembly 118. In various embodiments, distributing the force between the latch 404 and the latch assembly 118 may prevent the latch 404 from either becoming deformed or breaking under the force, thereby keeping the lid 112 in a closed position.
In certain embodiments, the lid 112 includes a natural bend and flex. As seen in the present embodiment, the lift tab 120 in its natural state extends away from the exemplary tub 100. In particular embodiments, the natural bend and flex of the lid 112 allows for the lift tab 202 to remain in a latched position. According to various aspects of the present disclosure, the initial form of the lid 112, as developed during manufacturing, may be the source of the outward force allowing the lift tab 202 to remain in a latched position. Moreover, the natural bend and flex of the lid 112 allows for the lift tab 202 to extend back outward after being pressed inward by a user or handler of the exemplary tub 100, according to one embodiment of the present disclosure.
In one embodiment, the support ribs 206 are shown accepting the upper rim 208 of the exemplary tub 100. According to various aspects of the present disclosure, the support ribs 206 may provide support to the exemplary tub 100 and prevent the exemplary tub 100 from being compressed or deformed under extreme conditions. For example, consider a scenario where the exemplary tub 100 is exposed to forces pushing inward on the sides of the exemplary tub 100. In this scenario, the support ribs 206 may prevent the upper rim 208 from bending inward, and thus preventing the exemplary tub 100 from becoming deformed and thus preventing unintended access to the contents of the exemplary tub 100.
Turning now to FIG. 7, an embodiment similar to FIG. 6 is shown with the breakable tab 120 removed. In one embodiment, removing the breakable tab 120 allows for a user to access the lift tab 202. In various embodiments, the breakable tab 120 may be connected to the latch assembly 118 by means of perforated seams, fused corners, or other appropriate means of attachment. In particular embodiments, removing the breakable tab 120 may require a user or handler to exert a force, thereby ripping or tearing away the breakable tab 120. In other embodiments, the user may pop the breakable tab 120 inward or outward to dislocate the breakable tab 120 from its initial position. In various embodiments, once the breakable tab 120 has been removed, a user or handler of the exemplary tub 100 may push the lift tab 202 inward and then upward to open the lid. According to various aspects of the present disclosure, pushing the lift tab 202 inward positions the right-angled side of the latch tooth 604 away from the latch 404. Further, pushing the lift tab 202 upward after it has been pushed inward allows for the latch tooth 604 to avoid being prohibited by the latch 404. In one embodiment, the result of this action may be seen at FIG. 8.
Turning now to FIG. 8, the latch tooth 604 is shown in an intermediate removal position and is mostly removed from the lift tab chamber 602 and partially removed from the lift tab hole 204. In the present embodiment, the edge of the latch 404 is in contact with the space between two of the press ridges 606. In this embodiment, the press ridges 606 on the lift tab 202 may further prevent the lid 112 from opening or closing. In particular embodiments, pushing inward on the lift tab 202, and then either upward or downward, may allow for the lift tab 202 to further exit the lift tab chamber 602 or reenter the lift tab chamber 602.
Turning now to FIG. 9, the exemplary tub 100 is shown without the breakable tabs 120, according to one embodiment. In the present embodiment, the breakable tabs 120 may have been removed from the latch assembly 118. As seen previously in FIG. 2, the exemplary tub 100 may be manufactured and distributed with the lid 112 in an opened position and the breakable tabs 120 included on the latch assembly 118. In one embodiment, closing the lid 112 may result in the lift tabs 202 being secured in the latch assembly 118 behind the breakable tabs 120, as seen in FIG. 1. In particular embodiments, removing the one or more breakable tabs 120 allows access to the lift tab chamber 602. As seen in the present embodiment, positioned within the lift tab chambers 602 are the lift tabs 202. According to various aspects of the present disclosure, the latch tooth 604 of the lift tab 202 may be secured below the latch 404 when the lid 112 is in a closed position. In particular embodiments, the latch 404 is concealed behind the front face of the latch assembly 118. In one embodiment, the one or more press ridges 606 protrude outward from the lift tab 202. In certain embodiments, pushing inward and then upward on each lift tab 202 via the press ridges 606 allows for the latch tooth 604 to disengage the latch 404, thereby allowing the lid 112 to be lifted into the open position. In one embodiment, pushing inward and then upward on each lift tab 202 may be difficult for users that have under-developed dexterity skills (i.e., children), thereby preventing certain users from opening the lid 112.
FIG. 10 shows the exemplary tub 100 with the lid 112 in an open position and without the breakable tabs 120. As described above in the discussion of FIG. 9, pushing inward and then upward on each lift tab 202 via the press ridges 606 allows for the latch tooth 604 to disengage the latch 404, thereby allowing the lid 112 to be lifted into an open position. The present embodiment shows the result of the above described action. In certain embodiments, while being lifted from a closed position to an open position, the one or more lift tabs 202 are lifted upward through the lift tab chamber 602 and further through the lift tab holes 204.
Turning now to FIG. 11, an exemplary tub 1100 is shown according to one embodiment of the present disclosure. In various embodiments, the exemplary tub 1100 is an alternate embodiment of the exemplary tub 100. In the present embodiment, the exemplary tub 1100 includes features substantially similar to the exemplary tub 100 such as the tub body 1102, lid 1112, satellite ring 1114, latch assembly 1118, and breakable tab 1120. In particular embodiments, the lift tab 202, latch tooth 604, and latch 404 included on the exemplary tub 100 are also substantially similar to the same features on the exemplary tub 1100. In certain embodiments, the exemplary tub 1100 may have different dimensions than the exemplary tub 100; however, the functionality of the two tubs is substantially similar. In the present embodiment, the exemplary tub 1100 includes only one breakable tab 1120. In various embodiments, the exemplary tub 1100 (and other alternate embodiments) may include a plurality of breakable tabs 1120.
FIG. 12 shows a perspective view of an exemplary tub 1200, according to one embodiment of the present disclosure. In various embodiments, the exemplary tub 1200 is an alternate embodiment of the exemplary tub 100. In the present embodiment, the exemplary tub 1200 includes features substantially similar to the exemplary tub 100 such as the lid 1212, satellite ring 1214, latch assembly 1218, and breakable tab 1220. In particular embodiments, the lift tab 202, latch tooth 604, and latch 404 included on the exemplary tub 100 are also substantially similar to the same features on the exemplary tub 1200. As shown in the present embodiment, the first side 1202 of the exemplary tub 1200 includes a handle 1204. According to various aspects of the present disclosure, the handle 1204 is integrated or molded into the shape of the first side 1202 of the exemplary tub 1200. In various embodiments, the handle 1204 is formed by a recess 1206 in the first side 1202, the front 1215, and the rear 1216 of the exemplary tub 1200. In certain embodiments, the recess 1206 allows for a user or handler of the exemplary tub 1200 to easily grab the tub 1200 with a single hand. In some embodiments, a handle 1204 may be present on both the first side 1202 and the second side 1208 of the exemplary tub 1200. According to various aspects of the present disclosure, the general curvature of the first side 1202 and second side 1208 of the exemplary tub 1200 are substantially similar. As shown in the present embodiment, both the first side 1202 and second side 1208 of the exemplary tub 1200 extend straight downward from the satellite ring 1214 and then proceed to curve inward towards the bottom 1213 of the tub 1200, thereby reducing the volume of the exemplary tub 1200.
Continuing with FIG. 12, the handle 1204 includes a plurality of grip ridges 1210. In one embodiment, the plurality of grip ridges 1210 allows for a user or handler of the exemplary tub 1200 to better grasp the tub 1200. In various embodiments, the plurality of grip ridges 1210 protrudes slightly outward from the handle inner surface 1212 (as seen in FIG. 13). In other embodiments, the plurality of grip ridges 1210 may extend inward into the exemplary tub 1200 interior. In a particular embodiment, the grip ridges 1210 are vertically aligned along the handle inner surface 1211. In certain embodiments, the grip ridges 1210 may be horizontally aligned, diagonally aligned, crossed, or another appropriate pattern. In various embodiments, the handle 1204 may not include any grip ridges 1210 at all. In embodiments where the handle 1204 does not include grip ridges 1210, the handle inner surface 1211 may be bare or may include another surface that promotes an enhanced grip such as sandpaper, a tacky substance, etc. In particular embodiments, exemplary tub 1200 may include various types of handles (e.g., jug handles, etc.).
Turning now to FIG. 13, the present embodiment shows a bottom view of the exemplary container 1200. In various embodiments, the bottom 1213 of the exemplary tub 1200 includes a shape that is substantially different from the lid 1212. Referring back to FIG. 4, the bottom 108 of the exemplary tub 100 includes a shape and proportions that are substantially similar to the lid 112. Looking now at FIG. 13, the bottom 1213 of the exemplary tub 1200 includes the curvature of the first side 1202 and second side 1208, and the handle recess 1206. In one embodiment, the bottom 1213 resembles two disproportionate semi-circular halves, wherein the smaller semi-circular half is in near proximity to the handle 1204. In a particular embodiment, each handle recess 1206 reduces the surface area of the tub bottom 1213, thereby creating the smaller semi-circular half. In various embodiments, the handle 1204 tapers inward as the handle 1204 extends downward and bends inward from the satellite ring 1214 to the tub bottom 1213.
Continuing with FIG. 13, the curvature of the handle recess 1206 resembles a valley shape. In the present embodiment, the handle recess 1206 begins to curve inward at location 1321 into the exemplary tub 1200 interior. In one embodiment, the handle recess 1206 then forms a rounded bottom at location 1322. In various embodiments, the rounded bottom at location 1322 represents the inner most portion of the handle recess 1206 and therefore the inner most grab-able portion of the handle 1204. In certain embodiments, the handle recess 1206 then begins to curve outward to location 1323. In particular embodiments, the location 1323 is similar to location 1321 in that both locations are above or outside the inner most portion of the handle recess 1206, which is 1322 in the present embodiment.
Now referring to FIG. 14, an exemplary tub 1400 is shown with a lid 1450 in an open position, according to one embodiment of the present disclosure. In particular embodiments, the exemplary tub 1400 includes a satellite ring 1416. According to various aspects of the present disclosure, the satellite ring 1416 is a protruding ridge that extends outward from a tub body 1408. According to one embodiment, the satellite ring 1416 has a flat upper surface and round lower surface (not shown). In some embodiments, the satellite ring 1416 has a round upper surface (convex) and an inwardly round bottom surface (concave), whereby one satellite ring 1416 may accept a satellite ring of a separate tub in a stacked configuration (e.g., if the lids are in an open position). In particular embodiments, the satellite ring 1416 extends fully or partially around the body 1408 of the exemplary tub 1400. According to various aspects of the present disclosure, the satellite ring 1416 may provide a surface or location for the lid 1450 to meet and seal when in a closed position. In various embodiments, the satellite ring 1416 acts as a base or starting point from which other tub features extend. In one or more embodiments, the satellite ring 1416 may include plateaus 1410 at the front corners of the exemplary tub 1400 to facilitate stacking of one or more exemplary tubs (e.g., when the lids are in an open position). In one or more embodiments, the corners of the plateaus 1410 are substantially rounded, but may be straight if suitable to facilitate the functionality described herein.
In various embodiments, the exemplary tub 1400 includes a latch assembly 1418.
According to various aspects of the present disclosure, the latch assembly 1418 is a protruding ridge that extends outward from the tub body 1408. In certain embodiments, the satellite ring 1416 is at least partially integrated with the latch assembly 1418. In some embodiments, the latch assembly 1418 is entirely separate from the satellite ring 1416. In particular embodiments, the latch assembly 1418 may be between 1 in and 2 in (e.g., 1.5 in) in width. In certain embodiments, the latch assembly 1418 extends fully or partially around the body 1408 of the exemplary tub 1400 (e.g., as integrally formed with the satellite ring 1416 or without the satellite ring 1416).
According to various aspects of the present disclosure, the latch assembly 1418 includes one or more breakable tabs 1420. In various embodiments, the one or more breakable tabs 1420 are removable portions of the latch assembly 1418.

In these embodiments (and others), the one or more lid latch tabs 1452 may include or define a lid latch tab opening 1454 for engaging with a ledge when in a closed position (as will be discussed in greater detail in the discussion of FIG. 21). According to various aspects of the present disclosure, while transitioning from an opened position to a closed position, the lid latch tab 1452 included on the lid 1450 may align with and enter the lid latch tab holes 1402.
Turning now to FIG. 15, a perspective view of the latch assembly 1418 of an exemplary tub 1400 is shown, according to one embodiment of the present disclosure. In particular embodiments, the latch assembly 1418 includes one or more breakable tabs 1420. In certain embodiments, and as discussed above in relation to FIG. 14, the breakable tabs 1420 may be removably connected to the latch assembly 1418 by means of break tab gates 1406 (e.g., perforated seams, fused corners, or other appropriate means of attachment). In various embodiments, the break tab gates 1406 may include one or more protrusions. In at least one embodiment, the protrusions may be triangular or any suitable shape (e.g., rectangular, conic, etc.). In certain embodiments, the breakable tabs 1420 may be substantially similar in height to the latch assembly 1418 to help prevent access to the features included behind the breakable tabs 1420.
Continuing with the embodiment shown in FIG. 15, in at least one embodiment, the latch assembly 1418 may define a lid latch chamber 1702. In various embodiments, the lid latch chamber 1702 is defined by one or more walls (e.g., chamber walls 1708) that are integrally formed with the satellite ring (or rings) 1416 and the breakable tabs 1420.
According to particular embodiments, the lid latch chamber 1702 includes one or more latches 1404 to facilitate engagement with a lid latch tab 1452 (not shown) when the exemplary lid 1450 (not shown) is in a closed position. In some embodiments, the latch 1404 may be located behind the breakable tabs 1420 in a lid latch chamber 1702. In these embodiments (and others), the latch 1404 (or other suitable protrusion) may extend into the lid latch chamber 1702. In particular embodiments, the latch 1404 may include one or more latch lead-in ribs 1414. In certain embodiments, the latch lead-in ribs 1414 may provide structural support for the latch 1404 when the exemplary lid 1450 is in a closed position. According to various aspects of the present disclosure, the latch lead-in ribs 1414 may have a substantially triangular shape. As shown in the embodiment of FIG. 15, the latch lead-in ribs 1414 resemble right-angled triangles. In this embodiment (and others), the angled shape of the latch lead-in ribs 1414 provides a guide for the lid latch tab 1452 as it enters the lid latch chamber 1702 and engages with the latch 1404. In one or more embodiments, the latch 1404 may be any outwardly extending ridge and may resemble any shape that engages with another object (e.g., a hook). In a particular embodiment, the latch 1404 engages with the lid latch tab opening 1454 of the lid latch tab 1452. In various embodiments, the angled side of the latch lead-in ribs 1414 may allow for the lid latch tab 1452 to pass over the latch 1404 and engage therewith. In one embodiment, once the lid latch tab opening 1454 has passed over the latch lead-in ribs 1414, the shape of the latch 1404 may prevent the lid latch tab 1452 from generally becoming unlatched (e.g., without user or other intervention).
Now referring to FIG. 16, a top view of a latch assembly 1418 of an exemplary tub 1400 is shown, according to one embodiment of the present disclosure. The embodiment shown in FIG. 16 shows the features included within the lid latch chamber 1702. In some embodiments, the breakable tab 1420 may include one or more break tab lead-in ribs 1412 on the interior side of the breakable tab (e.g., the side that partially defines the lid latch chamber 1702). In at least one embodiment, the break tab lead-in ribs 1412 protect the integrity of the breakable tab 1420. In particular embodiments, the break tab lead-in ribs 1412 are directly across from the one or more latches 1404 (and latch lead-in ribs 1414a, 1414b, 1414c). In the embodiment shown in the figures, the exemplary tub 1400 includes three latch lead-in ribs 1414a, 1414b, 1414c. In various embodiments, an exemplary tub 1400 may include any suitable number of latch lead-in ribs 1414a, 1414b, 1414c (e.g., two, four, five, etc.).
As shown in FIG. 16, in at least one embodiment, the lid latch chamber 1702 is defined by the interior of the breakable tab 1420, a portion of one or more satellite rings 1416, and portion of the tub body 1408. As also shown in FIG. 16, in some embodiments, the lid latch chamber 1702 may generally be open at the top and bottom (e.g., there may be no structure defining a top and bottom of the lid latch chamber 1702 such that the chamber may be accessed at the top or bottom portion). According to various aspects of the present disclosure, at least two lid latch chamber walls 1708 at least partially define the space of the lid latch chamber 1702 (in conjunction with the breakable tab 1420 and the satellite ring 1416). In particular embodiments, the lid latch chamber walls 1708 are perpendicular to, and extend from the tub body 1408, and form a portion of the satellite ring 1416, thereby defining a space outward from the tub body 1408 (e.g., the lid latch chamber 1702). In certain embodiments, the lid latch chamber walls 1708 may be integrally formed with the satellite ring 1416 and the tub body 1408.
FIG. 17 shows a cross section taken through the latch assembly 1418 of an exemplary tub 1400 with the lid 1450 in an open position (indicated by the dashed line B-B in FIG. 14), according to one embodiment of the present disclosure. In the present embodiment, the cross section shows a lid latch chamber 1702 including the latch 1404 for engaging with a lid latch tab 1452. In at least one embodiment, as discussed above, the lid latch chamber 1702 includes lid latch chamber walls 1708 (integrally formed with the satellite ring 1416) extending perpendicularly from the tub body 1408. In one or more embodiments, only one side of the lid latch chamber walls 1708 is integrally formed or connected to an adjacent portion of the exemplary tub 1400. In various embodiments, the lid latch chamber walls 1708 not only define the space of the lid latch chamber 1702, but also provide structural support to the latch assembly 1418. In certain embodiments, the lid latch chamber walls 1708 may be triangular shaped, rectangular shaped, quadrant shaped, or any other suitable shape.
FIG. 17 also shows a cross section of the breakable tab 1420, according to one embodiment of the present disclosure. In various embodiments, the breakable tab 1420, in conjunction with the satellite ring 1416 and the lid latch chamber walls 1708, define the space of the lid latch chamber 1702. In some embodiments, the upper portion of the breakable tab 1420 may be in substantially the same plane as the upper surface of the satellite sing 1416. In particular embodiments, and as discussed above, the breakable tab 1420 may prevent children, or any user with under-developed dexterity skills, from opening the exemplary tub 1400 until the breakable tab 1420 is removed.
In the embodiment shown in FIG. 17, located on the upper portion of the breakable tab 1420, a cross section of a break tab lead-in rib 1412 is shown.

In other embodiments, the break tab lead-in rib 1412 may have a rectangular shape, quadrant shape, or any other suitable shape. As described previously in the discussion of FIG. 16, the break tab lead-in rib 1412 provides structural support and protects the integrity of the breakable tab 1420. More specifically, the break tab lead-in rib 1412 may prevent the breakable tab 1420 from being warped, curved, or otherwise deformed when unexpected pressure is applied to the breakable tab 1420.
Continuing with the embodiment shown in FIG. 17, the one or more break tab lead-in ribs 1412 and the one or more latches 1404 may define a gap 1704. In various embodiments, the gap 1704 allows the lid latch tab 1452 (not shown) to pass between the break tab lead-in ribs 1412 and the latch 1404. In one or more embodiments, the gap 1704 may be less than one-quarter of an inch wide (e.g., 0.1 in, 0.045 in, 0.025 in, etc.). In particular embodiments, the gap 1704 may be any suitable distance to facilitate the functionality described herein.
Turning now to FIG. 18, a perspective view of a lid latch tab 1452 of an exemplary lid 1450 is shown, according to one embodiment of the present disclosure. In particular embodiments, the lid latch tab 1452 is substantially trapezoidal in shape and may feature rounded corners at the bottom portion 1804 of the lid latch tab 1452. In one or more embodiments, the lid latch tab 1452 may be rectangular, circular, or any other suitable shape. In at least one embodiment, the corners at the bottom portion 1804 of the lid latch tab 1452 are substantially straight (e.g., not rounded). In certain embodiments, and as discussed above, the lid latch tab 1452 may define a lid latch tab opening 1454 for engaging with the latch 1404 described above when the exemplary lid 1450 is in a closed position. In various embodiments, the lid latch tab opening 1454 is substantially oval in shape. In some embodiments, the lid latch tab opening 1454 may be circular, rectangular, or any other shape suitable for engaging with latch 1404.
FIG. 19 shows a cross sectional view of a latch 1452 of an exemplary lid 1450, according to one embodiment of the present disclosure. In one or more embodiments, the sides 1802 of the lid latch tab 1452 gradually increase in width from the bottom portion 1804 of the lid latch tab 1452 to the point 1808 where the bottom portion 1804 of the lid latch tab 1452 meets the top portion 1806 of the lid latch tab 1452. At that point 1808, in at least one embodiment, the sides 1802 of the lid latch tab 1452 begin to gradually decrease in width.
In particular embodiments, the exemplary lid 1450 may include a plurality of lid support ribs 1902. According to various aspects of the present disclosure, the plurality of lid support ribs 1902 are located along the inner curved portion of the lid 1450. In certain embodiments, the lid support ribs 1902 may be molded onto the curved portion of the lid 1450 during the manufacturing process. According to various aspects of the present disclosure, the plurality of lid support ribs 1902 may include rounded ends 1904 that may extend into the interior of an exemplary tub 1450 when the lid 1450 is in a closed position. In one or more embodiments, the lid support ribs 1902 may provide support to the exemplary tub 1400 and prevent the exemplary tub 1400 from being compressed or deformed under certain conditions when in a closed position.
Now referring to FIG. 20, a perspective view of the latch assembly 1418 of an exemplary tub 1400 engaged with a lid latch tab 1452 of an exemplary lid 1450 is shown, according to one embodiment of the present disclosure. FIG. 20 shows the breakable tab 1420 as it functions to prevent access to the lid latch tab 1452 and/or lid latch chamber 1702 when the lid latch tab opening 1454 is engaged with the latch 1404 when the exemplary lid 1450 is in a closed position. In particular embodiments, when the exemplary lid 1450 is in a closed position, the upper portion 1806 of the lid latch tab 1452 is at approximately the same elevation from the bottom of the exemplary tub 1400 as the top of the latch assembly 1418. In various embodiments, the breakable tab 1420 is positioned such that each end of the breakable tab 1420 is in contact with a portion of the satellite ring 1416 such that the breakable tab 1420 occludes the lid latch chamber 1702. In one or more embodiments, and as discussed above, the breakable tab 1420 prevents access to the lid latch chamber 1702 and thereby the lid latch tab 1452, such that the lid latch tab 1452 cannot be disengaged from the latch 1404 without first removing the breakable tab 1420.
Turning now to FIG. 21, a cross sectional view of a latch assembly 1418 of an exemplary tub 1400 engaged with the lid latch tab 1452 of an exemplary lid 1450 is shown, according to one embodiment of the present disclosure. In one or more embodiments, the lid latch tab 1452 is manufactured to remain in close contact with the tub body 1408 when in a resting position. In certain embodiments, the distance between the tub body 1408 and an end point of the lid latch tab 1452 is less than 0.075 in when in a resting position. In particular embodiments, when closing the exemplary lid 1450, a user pulls the lid latch tab 1452 away from the tub body 1408, such that the lid latch tab 1452 may pass over the latch 1404 (e.g., where the latch 1404 is between 0.075-0.15 in in length). In some embodiments, the sloping right triangle shape of the latch lead-in ribs 1414 allows the lid latch tab 1452 to slide down the latch lead-in ribs 1414 and over the one or more latches 1404 to engage with the one or more latches 1404. In at least one embodiment, upon passing over the one or more latches 1404, the lid latch tab 1452 returns to its resting position where it engages with the one or more latches 1404 and is restricted from opening (e.g., moving upwards). In various embodiments, the lid latch tab 1452 extends below the latch 1404 and into the lid latch chamber 1702. In these embodiments (and others), the portion of the lid latch tab 1452 extending below the latch 1404 provides a mechanism for a user to disengage (and engage) the lid latch tab 1452 from the latch 1404, such that the user may open the exemplary tub 1400 upon removal of the breakable tab 1420. As shown in FIG. 21, the breakable tab 1420 is of a sufficient height (e.g., 0.5 in to 1.5 in) such that a user may not access the portion of the lid latch tab 1452 extending below the latch 1404 without first removing the breakable tab 1420.
In various embodiments, and as discussed above in relation to FIG. 17, the latch assembly 1418 may include lid latch chamber walls 1708 to define the space of the lid latch chamber 1702 (in conjunction with the breakable tab 1420 and the satellite ring 1416). In one embodiment, the lid latch chamber walls 1708 extend downward from the upper portion of the latch assembly 1418 to the lowest portion of the breakable tab 1420. In various embodiments, the lid latch chamber walls 1708 extend down to the lowest portion of the breakable tab 1420 to prevent access to the lid latch tab 1452 while the breakable tab 1420 is attached to the latch assembly 1418.
Continuing with FIG. 21, in various embodiments, when the exemplary lid 1450 is in a closed position, a gap 2102 may be located between the latch 1404 and the bottom of the inner circumference of the lid latch tab opening 1454. In certain embodiments, the gap facilitates the opening and closing of the exemplary tub 1400 by allowing the latch 1404 (and latch lead-in ribs 1414) to at least partially extend through the lid latch tab opening 1454. In one or more embodiments, the gap 2102 may be less than one-tenth of an inch wide (e.g., 0.05 in, 0.025 in, 0.015 in, etc.). In particular embodiments, the gap 2102 may be any suitable distance to facilitate the functionality described herein.
FIG. 22 shows a front view of the lid latch chamber 1702 of an exemplary tub 1400 in which the breakable tab 1420 is removed and the exemplary lid 1450 is in a closed position, according to one embodiment of the present disclosure. In at least one embodiment, when the exemplary lid 1450 is in a closed position, a gap 2202 may be located between the upper portion of the chamber walls 1708 and the upper portion 1806 of the lid latch tab 1452. In various embodiments, the gap 2202 allows the lid latch tab 1452 to fit securely into the lid latch chamber 1702, such that the edges of the lid latch tab 1452 are not in contact with the lid latch chamber walls 1708. In this embodiment (and others), the gap allows the exemplary lid 1450 to smoothly transition from a closed position to an open position (and vice versa).
Continuing with the embodiment shown in FIG. 22, latch 1404 with three latch lead-in ribs 1414a, 1414b, 1414c are shown at least partially protruding through the lid latch tab opening 1454 as the latch 1404 is engaged with the lid latch tab 1452. In various embodiments, the width of the latch 1404 may be between 0.5 in and 1.5 in wide. In at least one embodiment, the width of the lid latch tab opening 1454 is greater than the width of the latch 1404 (e.g., the width of the lid latch tab opening 1454 may be 0.75 in, 1 in, 1.6 in, 2 in, etc.), such that the latch 1404 may extend through the lid latch tab opening 1454.
Referring now to FIG. 23, a cross sectional view of a latch assembly 1418 of an exemplary tub 1400 engaged with a lid latch tab 1452 of an exemplary lid 1450 with the breakable tab 1420 removed is shown, according to one embodiment of the present disclosure. In various embodiment, when the breakable tab 1420 is removed, a user may open a closed lid 1450 by accessing the portion of the lid latch tab 1452 extending below the latch 1404 and pulling out and lifting up the lid latch tab 1452 thereby disengaging the lid latch tab 1452 from the latch 1404.
