TECHNICAL FIELD

The present disclosure relates generally to containers, rings, and lids.

BACKGROUND

Containers are a widely used component in a variety of industries. Wholesalers, merchants, and individuals use containers in a plethora of industries including, but not limited to: manufacturing, agriculture, beverage, entertainment, health care, food services, hospitality, fishing, retail, automotive, transportation, waste management, oil and gas, education, and construction. The paint industry in particular, as a liquid-based industry, heavily depends on containers for the majority of its packing, storing, and shipping requirements. As such, improvements to the cost of paint- and other liquidcarrying containers may account for significant cost savings to a company’s bottom line.

Often, containers and lids may require adhesives or additional sealing materials to create a liquid-tight seal. Adhesives and additional sealing materials substantially raise the cost and time necessary to produce containers and lids. Therefore, there is a long-felt but unresolved need for containers and lids that may form a liquid-tight seal that does not require the use of adhesive or additional sealing materials. i BRIEF SUMMARY OF THE DISCLOSURE

Briefly described, and according to one embodiment, aspects of the present disclosure generally relate to containers and lids, and more particularly to containers including a separate ring and associated lid. The present disclosure discusses a novel and unique container that provides several improvements over existing, traditional containers in the paint and other industries that use containers, including, but not limited to: manufacturing, agriculture, beverage, entertainment, health care, food services, hospitality, fishing, retail, automotive, transportation, waste management, oil and gas, education, and construction. In various embodiments, the containers discussed herein have a lower cost of production and require less time to assemble than traditional containers for storing similar goods. In at least one embodiment, the present container includes a separate ring, which, in combination with the container design, may substantially eliminate the use of adhesives and additional sealing materials. In this embodiment and others, the present container may be assembled by applying pressure or force to the container or ring, either alone or in combination. Further, the lid may be attached to the container by applying pressure or force to the container, ring, or lid, either alone or in combination. Eliminating the need for adhesives and additional sealing materials allows the containers to be produced entirely out of plastic (e.g., Polyethylene, Polyethylene Terephthalate (PET), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Low-Density Polyethylene (LDPE), Polypropylene (PP), Polystyrene (PS), etc.).

The above and further features of the disclosed example container systems and assemblies (e.g., including a container, a ring, and a lid) will be recognized from the following detailed descriptions and drawings of particular embodiments. For example, the disclosed technology includes a container assembly that can include a container that can include a bottom surface and at least one sidewall circumscribing the bottom surface. The at least one sidewall can extend in a vertical direction from the bottom surface to an upper end thereby forming a cavity. The upper end can include an attachment portion and a latch tab extending from the attachment portion in a radial direction. The container assembly can include a ring that can include a container latch channel configured to at least partially receive the attachment portion of the container; the container latch channel can include an outer container latch channel (CLC) side, an inner CLC side, and a top CLC side. The ring can include a lid latch configured to engage a lid; the lid latch can include an inner lid latch side, a distal lid latch edge, and an outer lid latch side. The ring can include a bottom wall extending between the inner CLC side and the outer lid latch side. At least the inner CLC side, the bottom wall, and the outer lid latch side form a lid latch channel (i.e., the lid latch channel is formed by at least the inner CLC side, the bottom wall, and the outer lid latch side). The lid can include a ring latch channel configured to at least partially receive the lid latch of the ring. The latch tab can be configured to fold downwardly when the container latch channel at least partially receives the sidewall.

In some embodiments, the container latch channel can include a CLC protrusion extending from the top CLC side into the container latch channel. The CLC protrusion can be configured to engage the upper end of the container. The CLC protrusion can be substantially rectangular in shape. The outer CLC side can include one or more latch surfaces including a sloped surface extending in a sloped direction into the container latch channel. The sloped surface can form at least part of a latch protrusion for engaging latch tab. The latch protrusion can have a substantially trapezoidal cross-sectional shape. In certain embodiments, the ring can further include an underside surface, and an edge between the inner CLC side and the underside surface can be rounded or chamfered. The bottom surface can be substantially circular. Alternatively or in addition, the bottom surface can be substantially round. Alternatively or in addition, the bottom surface can be substantially rectangular. In some embodiments, a thickness of the at least one sidewall of the container can be less than a width of the container latch channel. Generally, the container can be a first single component, the ring can be a second single component, and the lid can be a third single component. Attachment of the ring to the container can form a liquid-tight seal between the ring and the container. Alternatively or in addition, attachment of the lid to the ring forms a liquid-tight seal between the lid and the ring. Accordingly, the combination of the container, the ring, and the lid can form a liquid-tight container assembly. The disclosed technology includes a system for sealing a container, and the system can include a ring configured to engage the container. The ring can include a container latch channel configured to accept a portion of the container and a lid latch configured to engage with a lid. The lid latch can include an inner lid latch side and an outer lid latch side, and at least a portion of the lid latch can extend in a radial direction. The ring can include a bottom wall extending between an inner wall of the container latch channel and the lid latch, and at least the inner wall of the container latch channel, the bottom wall, and the lid latch can form a lid latch channel. The lid can include a ring latch channel configured to at least partially receive the lid latch of the ring. The ring latch channel can include an inner ring latch sidewall, an outer ring latch sidewall, and a top ring latch surface. A width of the inner ring latch sidewall can increase from a first diameter at a bottom of the inner ring latch sidewall to second diameter at a latch notch and can decrease from the second diameter to a third diameter proximate the top ring latch surface.

In some embodiments, an upper portion of the outer lid latch side can be substantially convex. The top ring latch surface can be substantially rounded. The radial direction can be radially outward. The inner ring latch sidewall can include a ridged surface. The ring can further include a ring bead protrusion on the outer lid latch side, and the ring bead protrusion can extend into the lid latch channel. The ring bead protrusion can have a substantially trapezoidal cross-sectional shape. The inner ring latch sidewall can include a recess configured to at least partially receive and/or engage the ring bead protrusion. The outer ring latch sidewall can include a latch protrusion configured to engage the ring latch channel.

Turning now to FIG. 1, an exploded view of an exemplary container assembly 100 includes a container 200, ring 300, and lid 400 and is shown according to one embodiment of the present disclosure. In some embodiments, the container 200, ring 300, and lid 400 are circular in shape. In various embodiments, the container 200, ring 300, and lid 400 may be rectangular, square, or trapezoidal in shape. In various embodiments, the ring 300 attaches to the container 200 to facilitate a liquid-tight seal without any adhesives or additional sealing materials. In one or more embodiments, the ring 300 attaches to the container 200 by placing the bottom of the ring 300 snugly around the rim of the container 200 (as further discussed herein). Ring 300 interfaces with the rim of container 200 to snap securely into place. In one or more embodiments, the lid 400 attaches to the ring 300 by placing the bottom of the lid 400 snugly inside the ring 300 (as further discussed herein). Lid 400 interfaces with the inside of ring 300 to snap securely in place. When ring 300 is attached to container 200, and lid 400 is attached to ring 300, the ring 300, container 200, and lid 400 form an enclosed space with a liquid-tight seal without any adhesives or additional sealing materials (e.g., gaskets). In certain embodiments, the ring 300, container 200, and lid 400 are manufactured out of plastic (e.g., Polyethylene, Polyethylene Terephthalate (PET), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Low-Density Polyethylene (LDPE), Polypropylene (PP), Polystyrene (PS), etc.). In some embodiments, the ring 300, container 200, and lid 400 may be manufactured out of any material suitable to facilitate the functionality described herein.

In one embodiment, and as shown in FIG. 1, the container 200 includes a container body 210 and container rim 220. In some embodiments, the container body 210 may include graphical information (e.g., signage or label). In various embodiments, the container body 210 terminates at an open end, whereby the open end includes a container rim 220. In circular embodiments, the diameter of container 200 may be any suitable distance (e.g., 5.3 - 18.7 inches). In various embodiments, the height of container 200 may be any suitable distance (e.g., 4.5 - 30.9 inches). In various embodiments, the thickness of container body 210 may be any suitable width (e.g., 0.05 - 0.40 inches).

In circular embodiments, the diameter of ring 300 may be any suitable distance (e.g., 4.7 - 18.9 inches). In various embodiments, the height of ring 300 may be any suitable distance (e.g., 0.3 - 0.5 inches). In circular embodiments, the diameter of lid 400 may be any suitable distances (e.g., 4.5 - 18.3 inches). In various embodiments, the height of lid 400 may be any suitable distances (e.g., 0.2 - 0.5 inches). In certain embodiments, and as will be further discussed herein, the container rim 220 includes sealing components to facilitate a liquid-tight seal when engaged with a ring 300. In one or more embodiments, container rim 220 includes a latch channel to engage with corresponding sealing components on ring 300.

In various embodiments, at least a portion of the inner wall of lid latch channel 340 has a trapezoidal cross-sectional shape, which is at least partially defined by edge 360.

FIG. 3 A - 3C generally depict the incremental steps of an exemplary ring 300 as it is attached to a container 200, according to one embodiment of the present disclosure. Turning to FIG. 3A, a cross-sectional view of an exemplary ring 300 and container 200 in a separated configuration is shown. As shown in FIG. 3 A, as discussed in reference to FIG. 1, container 200 may include a container body 210 and container rim 220. In various embodiments, the container 200 includes sidewall 212 with an outer surface 260. In certain embodiments, sidewall 212 extends upward from the container bottom and transitions into a container rim 220 at the upper end of the container 200. As discussed above in reference to FIG. 1, the thickness of sidewall 212 may be any suitable distance (e.g., 0.06 - 0.20 inches).

In one or more embodiments, the container rim 220 extends outward (e.g., in a radially outward direction) from the sidewall 212 to form a lip or latch tab 224. Although not illustrated, the container rim 220 can include a latch tab 224 that extends inwardly (e.g., in a radially inward direction) from the sidewall 212 alternatively or in addition to a latch tab 224 extending outwardly. In various embodiments, latch tab 224 is a flat protrusion around the edge of container rim 220. In various embodiments, latch tab 224 has a thickness less than the thickness of sidewall 212. In some embodiments, latch tab 224 may have a thickness equal to, or greater than the thickness of sidewall 212. In at least one embodiment, latch tab 224 engages with a corresponding seal structure on ring 300, such that a liquid-tight seal may be formed between ring 300 and container 200. In certain embodiments, latch tab 224 is manufactured out of a flexible material such that latch tab 224 may fold down or otherwise deform. Alternatively or in addition, the latch tab 224 can be elastically deformable (i.e., the latch tab 224 can be configured to return to its original shape, position, or state upon removal of a deforming force).

In particular embodiments, the ring 300 includes container latch channel 320 formed at least in part by two sidewalls 308, 330 and a top wall 380, such as is shown in FIG. 3A. The container latch channel 320 can include one or more interior surfaces 332 (e.g., defined by the surface(s) of sidewall 308, sidewall 330, and/or top wall 380). In various embodiments, container latch channel 320 may be U-shaped. In some embodiments, container latch channel 320 may have a trapezoidal or rectangular cross- sectional shape. As will be understood from discussions herein, container latch channel 320 is configured to at least partially receive container rim 220 to create a seal between container 200 and ring 300. The width of container latch channel 320 may be any suitable distance that allows for container latch channel 320 to receive container rim 220 (e.g., 0.05 - 0.10 inches). The width of at least a portion of container latch channel 320 can be approximately equal to the width of at least a corresponding portion of container rim 220. Alternatively or in addition, the width of at least a portion of container latch channel 320 can be less than the width of the corresponding portion of container rim 220. The height of container latch channel 320 may be any suitable distance that allows for container rim 220 to engage with latch channel 320 (e.g., 0.15 - 0.65 inches). According to certain embodiments, container latch channel 320 may include a protrusion 382 on top wall 380. In various embodiments, protrusion 382 may be trapezoidal, rectangular, triangular, semi-circular, or circular in cross-sectional shape. In these embodiments (and others), when container 200 engages with ring 300, protrusion 382 can abut, deform, or otherwise engage with container 200 (e.g., an end surface of container rim 220) to ensure a tight fit between container 200 and ring 300.

In various embodiments, a latch protrusion 312 is located on the interior surface 332 and includes latch surface 304. The latch protrusion 312 can be or comprise a protrusion extending outwardly from the interior surface 332, as illustrated in FIGs. 3A- 3C. According to certain embodiments, latch protrusion 312 may be located on the outermost sidewall 308 and protrudes into container latch channel 320 (e.g., extending from the interior surface 332 in a radially inward direction). In various embodiments and as shown in FIG. 3 A, latch protrusion 312 is trapezoidal in shape. According to some embodiments, latch protrusion 312 may be triangular, rectangular, semi-circular, or circular in shape. As will be understood from discussions herein, container latch channel 320 can at least partially receive container rim 220. Latch protrusion 312 engages with latch tab 224 to create a liquid-tight seal between container 200 and ring 300. In particular, embodiments, and as will be discussed further herein, latch protrusion 312 engages with latch tab 224 to fold latch tab 224 flat against outer surface 260 upon insertion of the container rim 220 into container latch channel 320.

In various embodiments, latch surface 304 includes a surface portion 306. The surface portion 306 can be configured to initially contact or engage latch tab 224 or another portion of the container 200 upon insertion of the container rim 220 into container latch channel 320. Initial surface portion 306 can be sloped, as in FIGs. 3A- 3C. In at least one embodiment, surface portion 306 extends between the interior surface 332 of sidewall 308 and the peak (e.g., the most radially inward portion) of latch protrusion 312. According to various embodiments, sloped surface 306 is a flat, inclined surface. Alternatively, surface portion 306 can be rounded. The sloped or rounded nature of the surface portion 306 can bias or deform at least a portion of the container 200 (e.g., latch tab 224) upon insertion of the container rim 220 into container latch channel 320 and/or can bias or deform at least a portion of the ring 300 (e.g., sidewall 308) to accommodate a corresponding portion of the container 200 (e.g., container rim 220) in container latch channel 320. In certain embodiments, surface portion 306 facilitates folding latch tab 224 flat against outer surface 260. In particular embodiments, sloped surface 306 facilitates folding latch tab 224 flat against outer surface 260 by engaging latch tab 224 such that surface portion 306 gradually applies pressure to latch tab 224. In these embodiments (and others), the gradual pressure applied by surface portion 306 allows latch tab 224 to fold ninety degrees without snapping. In some embodiments, once folded ninety degrees, latch tab 224 is secured against latch surface 304 such that ring 300 and container 200 form a liquid-tight seal that does not require adhesives or additional sealing materials (e.g., gaskets). In various embodiments, surface portion 306 connects with edge 310 of sidewall 308. In particular embodiments, edge 310 is parallel to top wall 380. In at least one embodiment, the width of edge 310 is less than the thickness of sidewall 308. In some embodiments, the width of edge 310 is equal to the thickness of sidewall 308.

Continuing with the embodiment shown in FIGs. 3A-3C, the ring 300 includes a lid latch channel 340. In the embodiment shown in FIG. 3 A, lid latch channel 340 is formed by two sidewalls 330 and 325 and bottom wall 316. In various embodiments, lid latch channel 340 may be generally U-shaped. In some embodiments, lid latch channel 340 may be trapezoidal or rectangular in cross-sectional shape. As will be understood from discussions herein, lid latch channel 340 receives at least a portion of a lid (e.g., lid 400 as discussed in relation to FIG. 1) to create a seal between ring 300 and the lid. The width of lid latch channel 340 may be any suitable distance that allows for lid latch channel 340 to receive the lid (e.g., 0.5 - 1.5 inches). For example, the width of at least a portion of lid latch channel 340 can be approximately equal to the width of at least a corresponding portion of the lid. Alternatively or in addition, the width of at least a portion of lid latch channel 340 can be less than the width of the corresponding portion of the lid. The height of lid latch channel 340 may be any suitable distance that allows for container rim 220 to engage with lid latch channel 340 (e.g., 0.2 - 0.5 inches).

According to various embodiments, sidewall 325 includes side surface 318 and/or side surface 334. In certain embodiments, sidewall 325 ends at edge 360. In various embodiments, sidewall 325 includes a surface 322 that is sloped and/or rounded in a downwardly direction (e.g., from edge 360 in a radially inward direction towards the center of ring 300). In embodiments that include sloped surface 322 and as shown in FIG. 3A, edge 360 of sidewall 325 is trapezoidal in cross-sectional shape.

In various embodiments, sidewall 325 includes ring bead 326. In one or more embodiments, ring bead 326 protrudes into lid latch channel 340. In some embodiments, and as will be understood from discussions herein, lid latch channel 340 at least partially receives the lid. In particular embodiments, ring bead 326 engages with a surface of the lid to create a liquid-tight seal between ring 300 and the lid. In various embodiments and as shown in FIG. 3 A, ring bead 326 is trapezoidal in cross-sectional shape. According to some embodiments, ring bead 326 may be triangular, rectangular, semi-circular, or circular in cross-sectional shape.

Alternatively, the edge separating the interior surface 332 and the underside surface 370 can be curved or rounded. In various embodiments, underside surface 370 is a flat surface that is generally parallel to bottom wall 316.

Now referring to FIG. 3B, a cross-sectional view of an exemplary ring 300 and container 200 is shown. According to the embodiment shown in FIG. 3B, ring 300 is shown immediately prior to engaging container 200 (e.g., portions of the ring 300 are abutting or otherwise in contact with the container 200 but the ring 300 is not yet attached to the container 200). In various embodiments, container rim 220 and latch tab 224 line up with the opening of container latch channel 320. In particular embodiments, sidewall 212 is partially flush with interior surface 332, and latch tab 224 is in contact with edge 310. According to various embodiments and as shown in FIG. 3B, latch tab 224 is partially flush with edge 310 or otherwise in contact with edge 310 and/or sloped surface 306. In some embodiments, latch tab 224 may be entirely flush with edge 310. In various embodiments, edge 310 is parallel to latch tab 224 immediately prior to ring 300 engaging container 200.

Now referring to FIG. 3C, a cross-sectional view of an exemplary ring 300 and container 200 in an attached configuration is shown. According to various embodiments, once the corresponding seal structures on ring 300 and container 200 are aligned, ring 300 may be attached to container 200 by applying pressure or force to either or both container 200 and ring 300 such that container latch channel 320 at least partially receives container rim 220. As shown in FIG. 3C, container latch channel 320 can at least receive container rim 220. In particular embodiments, and as discussed in reference to FIG. 3B, container rim 220 and latch tab 224 line up with the opening of container latch channel 320 and latch tab 224 is in contact with edge 310 and/or sloped surface 306. In these embodiments (and others), once pressure or force is applied to either or both container 200 and ring 300, sloped surface 306 engages with latch tab 224 such that sloped surface 306 transfers pressure to latch tab 224 and biases latch tab 224 downward. In various embodiments, the pressure transferred by sloped surface 306 allows latch tab 224 to bend or fold downwardly (e.g., ninety degrees relative the starting position of the latch tab 224 shown in FIG. 3 A, for example) without snapping or cracking. In some embodiments, sloped surface 306 and/or latch surface 304 fold latch tab 224 such that at least a portion of latch tab 224 is flush against, or otherwise in contact with, outer surface 260. In at least one embodiment, once folded downward, latch tab 224 is secured against latch surface 304 such that latch surface 304 prevents container rim 220 from sliding out of container latch channel 320. Further, in some embodiments, protrusion 382 deforms container rim 220 slightly to ensure a tight-fit between container rim 220 and container latch channel 320.

In various embodiments, the seal formed by container rim 220 engaging container latch channel 320 is a liquid-tight seal between ring 300 and container 200 that requires no adhesives or additional sealing materials (e.g., a separate O-ring). In particular embodiments, this liquid-tight seal may be formed simply by lining up container rim 220 and container latch channel 320 and applying pressure or force to either or both container 200 and ring 300. In at least one embodiment, no adhesives or additional sealing materials are necessary to attach container 200 to ring 300. In certain embodiments, this liquid-tight seal provides significant advantages such as decreasing the cost of production and materials and the time necessary to assemble. In these embodiments (and others), the folding latch tab 224 allows for container 200 and ring 300 to be manufactured from lower costs materials such as plastic (e.g., Polyethylene, Polyethylene Terephthalate (PET), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Low-Density Polyethylene (LDPE), Polypropylene (PP), Polystyrene (PS), etc.). In several embodiments, the liquid-tight seal allows container 200 to be used to store various liquids and other materials, including, but not limited to: paints, oils, food, consumer goods, construction materials, inks, chemicals, lubricants, adhesives, coatings, roofing mastics, driveway sealers, flavorings, sanitation supplies, building products, ice melt compounds, powders, pet food, and other such materials.

In at least one embodiment and as shown in FIG. 8, a portion of base 246 rests on top surface or wall 380 such that container 200 is stacked on top of container 200. In some embodiments, a portion of base 246 rests above lid latch channel 340. In various embodiments, base 246 may rest entirely on top surface380. In particular embodiments, base 246 may fit into, and/or at least partially extend into, lid latch channel 340 (e.g., when the container assembly 100 of which base 246 is a part is stacked atop another container assembly 100).

Referring now to FIG. 9, a cross-sectional view of a first exemplary container 200 stacked on top of a second exemplary container 200 in an attached configuration with ring 300 and lid 400 is shown, according to one embodiment of the present disclosure.

According to various embodiments, container 200 may include lower leg 234. In one or more embodiments, lower leg 234 extends below and runs parallel to container body 210. In various embodiments, lower leg 234 may be a suitable length such that container 200 would not tip over (e.g., 0.1 - 0.5 inches). In one embodiment, lower leg 234 includes base 246 located on the bottom of lower leg 234. In various embodiments, base 246 is a flat surface that provides support to container 200 when rested on a surface.

According to various embodiments, container 200 may also include upper leg 232. In various embodiments, upper leg 232 also extends below container body 210. In certain embodiments, upper leg 232 slopes away from container body 210 such that upper leg 232 and lower leg 234 form a groove on the bottom of container body 210. In one or more embodiments, and as discussed further herein, upper leg 232 and lower leg 234 provide stability and load distribution when stacking container 200 on top of container 200 with ring 300 and lid 400 attached. In particular embodiments, upper leg 232 may provide stability and load distribution by preventing container 200 from falling over in the case of tipping. In various embodiments and as shown in FIG. 9, ring 300 includes top surface 380. In at least one embodiment and as shown in FIG. 9, a portion of base 246 rests on top surface 380 such that container 200 is stacked on top of container 200. In certain embodiments, a portion of base 246 rests above lid latch channel 340. In various embodiments, base 246 may rest entirely on top surface380. In particular embodiments, base 246 may fit into, and/or at least partially extend into, lid latch channel 340 (e.g., when the container assembly 100 of which base 246 is a part is stacked atop another container assembly 100).
