DETAILED DESCRIPTION
Selected embodiments will now be explained with reference to the drawings. it will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
FIGS. 1-17 illustrate a first example embodiment of a food container 10 in accordance with the present disclosure. In the illustrated embodiment, the food container 10 includes a body 12 and a lid assembly 14. The lid assembly 14 is removeable from the body 12. The lid assembly 14 is configured to provide an airtight seal which can be easily sealed and unsealed by a rotational force provided by a user. In an embodiment, the food container 10 is approximately 8″ (length)×6.5″ (width)×8.5″ (height).
In the illustrated embodiment, the body 12 includes a bottom wall 15 and at least one side wall 16 which form an interior space 18. The top of the body 12 is open (see FIG. 7) and configured to receive the lid assembly 14. As seen in FIGS. 3 and 4, the side wall(s) 16 form a symmetrical shape on opposite sides from the top and bottom views. Both the body 12 and the lid assembly 14 have a football-like shape from the top and bottom views, with the horizontal length from the top and bottom views being longer than the vertical length. The construction of the lid assembly 14 as described herein enables this shape or other types of irregular shaped containers to be sealed by a rotational force provided by a user.
As seen in FIG. 5, the illustrated lid assembly 14 protrudes past the top of the side wall(s) 16 when the lid assembly 14 is attached to the body 12. The body 12 can be at least partially transparent so that the food located within the interior space 18 is visible from the outside. The body 12 can also be tinted to reduce light exposure on food located within the interior space 18. The body 12 can also be opaque. The body 12 can be formed from plastic, for example, from acrylonitrile butadiene styrene (ABS) material. As should be understood by those of ordinary skill in the art from this disclosure, the body 12 can also be formed in another suitable shape or from another suitable material.
In the illustrated embodiment, the lid assembly 14 includes a base part 20, a rotating part 22, a first slide part 24, a second slide part 26, and a sealing part 28. The base part 20 and rotating part 22 have a center axis about which the rotating part 22 rotates with respect to the base part 20. In use, the rotating part 22 rotates around its center axis with respect to the base part 20 to seal or unseal the interior space 18 of the body 12. The rotation of the rotating part 22 causes the first slide part 24 and the second slide part 26 to translate radially in opposite directions away from the center axis. The first slide part 24 and the second slide part 26 translate linearly with respect to the base part 20, the rotating part 22, and the sealing part 28. During translation in the outward radial direction (away from the central axis), the first slide part 24 and the second slide part 26 press the sealing part 28 into the side wall(s) 16 of the body 12, thus sealing the interior space 18 with an airtight seal. During translation in the inward radial direction (toward the central axis), the first slide part 24 and the second slide part 26 release the pressure pressing the sealing part 28 into the side wall(s) 16 of the body 12, thus unsealing the airtight seal provided to interior space 18 by the lid assembly 14.
As seen for example in FIGS. 7-10, the base part 20 includes a top surface 30, a bottom surface 32, and a side surface 33. The base part 20 includes a cavity 34 in the top surface 30. The cavity 34 receives the rotating part 22 such that the rotating part 22 is at least partially rotatable within the cavity 34. The base part 20 can be formed from plastic, for example, from ABS material. As should be understood by those of ordinary skill in the art from this disclosure, the base part 20 can also be formed from any other suitable material.
In the illustrated embodiment, and as shown in FIG. 10, the base part 20 includes a first protrusion 36. The first protrusion 36 extends upward from the center of the cavity 34 and is aligned with the center axis of the rotating part 22. In the illustrated embodiment, the rotating part 22 attaches to the first protrusion 36 to attach the rotating part 22 to the base part 20 such that the rotating part 22 rotates with respect to the base part 20. The rotating part 22 can attach to the first protrusion 36, for example, via a snap fit, press fit, or another attachment mechanism. Those of ordinary skill in the art will recognize from this disclosure that there are various ways to rotationally attach the rotating part 22 to the base part 20.
In the illustrated embodiment, and as shown in FIGS. 14-16, the base part 20 includes at least one second protrusion 38. The second protrusions 38 extend downward from the bottom surface 32. In the illustrated embodiment, the second protrusions 38 extend downward from a portion of the bottom surface 32 that is radially outward from the cavity 34. As explained in more detail below, each second protrusion 38 interacts with the first slide part 24 or the second slide part 26 to restrict the first slide part 24 or the second slide part 26 to linear translation with respect to the base part 20. More specifically, each second protrusion 38 interacts with the first slide part 24 or the second slide part 26 to restrict the first slide part 24 or the second slide part 26 to linear translation in the radially outward and radial inward directions with respect to the center axis of the base part 20.
in the illustrated embodiment, and as shown in FIG. 16, the base part 20 includes at least one aperture 39. In the illustrated embodiment, the base part 20 includes four apertures 39 which are curved around the perimeter of the cavity 34. Here, the apertures 39 are positioned through the top surface 30 and bottom surface 32 at a position radially outward from the cavity 34. As explained in more detail below, each aperture 39 receives a second protrusion 48 of the rotating part 22 to allow the second protrusion 48 to interact with a slide part 24, 26 during rotation of the rotating part 22. As seen in FIG. 16, the second protrusions 48 are longer than the depths of their respective apertures 39 so as to extend beyond their respective apertures 39 and contact the first slide part 24 or second slide part 26.
As seen for example in FIGS. 7-10, the rotating part 22 includes a top surface 40, a bottom surface 42, and a side surface 43. The rotating part 22 includes one or more rotation assisting device which can be used by a user to rotate the rotating part 22 with respect to the base part 20. Here, the rotation assisting device includes one or more finger indentations 44 in the top surface 40. In the illustrated embodiment, the rotating part 22 includes four finger indentations 44. More or less finger indentations 44 can be used. In the illustrated. embodiment, a user places his or her fingers in the finger indentations 44 to rotate the rotating part 22 with respect to the base part 20. As seen in FIG. 10, the finger indentations 44 extend into the cavity 34 when the rotating part 22 is attached to the base part 20. Alternatively, for example, the rotation assisting device can include one or more protrusion which extends upward from the top surface 40 which a user grabs to cause rotation of the rotating part 22. The rotating part 22 can be formed from plastic, for example, from ABS material. As should be understood by those of ordinary skill in the art from this disclosure, the rotating part 22 can also be formed in another suitable shape or from another suitable material. In an embodiment, the diameter of the rotating part is about 5 inches.
In the illustrated embodiment, and as seen in FIG. 10, the rotating part 22 includes a first protrusion 46 extending downward from the bottom surface 42. In the illustrated embodiment, the first protrusion 46 attaches to the first protrusion 36 of the base part 20 to rotatably attach the rotating part 22 to the base part 20. Here, the first protrusion 46 is located between the finger indentations 44. As seen in FIG. 10, the first protrusion 46 can extend into a center aperture in the first protrusion 36. The first protrusion 46 can attach to the first protrusion 36, for example, via a snap fit, press fit or another attachment mechanism. Those of ordinary skill in the art will recognize from this disclosure that there are various ways to rotationally attach the rotating part 22 to the base part 20.
In the illustrated embodiment, and as seen in FIGS. 14-16, the rotating part 22 includes at least one second protrusion 48. A.s explained in more detail below, each second protrusion 48 interacts with the first slide part 24 or the second slide part 26 so that rotation of the rotating part 22 causes the first slide part 24 or the second slide part 26 to translate with respect to the base part 20. More specifically, each second protrusion 48 interacts with the first slide part 24 or the second slide part 26 to cause the first slide part 24 or the second slide part 26 to translate radially outward and radially inward with respect to the base part 20.
As seen in FIG. 14 and 15, the slide parts 24, 26 can be similarly or even identically formed. Each slide part 24, 26 includes a top surface 50, a bottom surface 52, and a side surface 53. Each slide part 24, 26 includes at least one first aperture 54 which interacts with the at least one second protrusion 38 of the base part 20. In the illustrated embodiment, each slide part 24, 26 includes three first apertures 54. As illustrated, the first apertures 54 are straight apertures which are elongated in the radial direction that the slide part 24, 26 translates. Each slide part 24, 26 also includes at least one second aperture 56 which interacts with at least one second protrusion 48 of the rotating part 22. In the illustrated embodiment, each slide part 24, 26 includes two second apertures 56. As illustrated, the second apertures 56 are curved. with respect to the rotational center axis. In the illustrated embodiment, the second apertures 56 are located radially outward from the cavity 34 when the lid assembly 14 is assembled. In the illustrated embodiment, the first apertures 54 and the second apertures 56 extend all the way through the respective slide part 24, 26 between the top surface 50 and the bottom surface 52. Alternatively, the first apertures 54 and/or the second apertures 56 can be formed as indentations in the top surface 50 but not extend through the slide part 24, 26 to the bottom surface 52. The slide parts 24, 26 can be formed from plastic, for example, from ABS material. As should be understood by those of ordinary skill in the art from this disclosure, the slide parts 24, 26 can also be formed in other suitable shapes or from another suitable material.
In the illustrated embodiment, and as seen in FIGS. 12 and 13, each slide part 24, 26 includes an outer side surface 58. In the illustrated embodiment, the outer side surface 58 has a contour that corresponds to that of the outer edge of the sealing part 28. In the illustrated embodiment, the outer side surface 58 also has a contour that corresponds to the contour of the side wall(s) 16 of the body 12. As seen in FIG. 17, the outer side surface 58 can be curved in the axial direction of the center axis (vertical in FIG. 17) such that a portion of the outer side surface 58 (here, the center in the vertical direction) applies increased pressure against the sealing surface 28 when the lid assembly 14 seals the interior space 18. As also illustrated in FIG. 17, the side surface 58 can be longer in the axial direction of the center axis (vertical in FIG. 17) than other portions of the slide part 24 (here, shown by the T-shape). In the illustrated embodiment, the side surface 58 is longer in the axial direction than the portions of the slide part 24, 26 including the first apertures 54 and/or the second apertures 56.
The sealing part 28 includes a top surface 60, a bottom surface 62, and a side surface 64. As seen for example in FIG. 7, the top surface 60 forms a cavity 66 with an aperture 68 in the center thereof. The aperture 68 receives the base part 20 with the slide parts 24, 26 located around the perimeter thereof. As seen for example in FIG. 17, the sealing surface can be attached to the base part 20 at or near the outer perimeter of the base part 20, In the illustrated embodiment shown in FIG. 17, the edge of the sealing part is received into an indentation in the base part. As also see in FIG. 17, when the sealing part is attached, the sealing part encloses the first slide part 24 and/or the second slide part 26 with the side surface 64 located between the outer side surface 58 of the slide part 24, 26 and the side wall(s) 16 of the body 12. When the slide part 24, 26 translates to seal the interior space (translates leftward in the detailed view of FIG. 17), the outer side surface 58 of the slide part 24, 26 presses the side surface 64 of the sealing part 28 into the side wall(s) 16 of the body 12.
The sealing part 28 is formed from a flexible material, for example silicon. As should be understood by those of ordinary skill in the art from this disclosure, the sealing part 28 can also be formed from another suitable material.
In the illustrated embodiment, the food container 10 further includes a base 70. The base 70 fits around the body 12 at the bottom wall 15. More specifically, the base 70 fits around. the edges of the body 12 where the side walls 16 meet the bottom wall 15. As seen in FIG. 7, in the illustrated embodiment, the base 70 is open in the center to leave a portion of the bottom wall 15 exposed. In an alternative embodiment, for example as seen in FIG. 18, the base 70 can cover the entire bottom wall 16 of the body 12. The base 70 can be formed from a material such as rubber, for example, EPDM α durometer rubber. As should be understood by those of ordinary skill in the art from this disclosure, the base 70 can also be formed from any other suitable material.
As seen in FIGS. 14 to 16, the second protrusions 38 of the base part 20 extend into the first apertures 54 of a slide part 24, 26. Here, the second protrusions 38 each include an edge with an outwardly extending lip which causes a snap fit to attach the slide part 24, 26 to the base part 20. When configured as shown, the interaction between the second protrusions 38 and the first apertures 54 permits back and forth translation of the slide part 24, 26 with respect to the base part 20 in a linear direction. More specifically, the interaction between the second protrusions 38 and the first apertures 54 permits radially inward and radially outward translation with respect to the rotational center axis. In the illustrated embodiment, the interaction between the second protrusions 38 and the first apertures 54 restricts translation of the slide part 24, 26 to only the linear direction with respect to the base part 20.
As also seen in FIGS. 14 to 16, the second protrusions 48 of the rotating part 22 extend through the apertures 39 of the base part 20 and into the second apertures 56 of a slide part 24, 26. As seen in FIGS. 14 and 15, each second aperture 56 extends from a first end 72 to a second end 74. In the illustrated embodiment, the first end 72 is closer to the center axis of the lid assembly 14 than the second end 74. This way, rotation of the rotating part 22 in a first direction (e.g., counterclockwise toward the first end 72 in the perspective of FIGS. 14 and 15) pushes the slide parts 24, 26 radially outwardly with respect to the center axis, while rotation of the rotating part 22 in an opposite second direction (e.g., clockwise toward the second end 74 in the perspective of FIGS. 14 and 15) pushes the slide parts 24, 26 radially inwardly with respect to the center axis.
FIG. 14 illustrates the lid assembly in the unsealed configuration, while FIG. 15 illustrates the lid assembly in the sealed configuration. As seen in FIG. 14, when the second protrusions 48 are located at the second ends 74, the slide parts 24, 26 are at their innermost configuration. This is the unsealed configuration. As seen in FIG. 15, when the second protrusions 48 are located at the first ends 72, the slide parts 24, 26 are at their outermost configuration. This is the sealed configuration. In the sealed configuration, the slide parts 24, 26 apply pressure against the sealing part 28 at one or more pressure points 76, as seen for example in FIG. 9. More specifically, the side surface 58 of the slide parts 24, 26 apply pressure against the sealing part 28. This pressure presses the side surface 64 of the sealing part 28 into the side wall(s) 16 of the body 12 to seal the interior space 18. The first ends 72 and/or second ends 74 can include indentations or protrusions which receive the second protrusions 48 to maintain the sealed or unsealed configuration until rotational pressure is applied by a user.
Thus, in use, when the rotating part 22 is rotated with respect to the base part 20, the second protrusions 48 push the slide parts 24, 26 outwardly or inwardly with respect to the other the parts of the lid assembly 14. This causes the sealing part 28 to press against the side surface(s) 16 of the body 12. The interaction between the second protrusions 38 of the base part 20 and the first apertures 54 of the slide parts 24, 26 ensure that the slide parts 24, 26 translate linearly while being pushed by the second protrusions 48.
In the illustrated embodiment, the amount of rotation by the rotating part 22 needed to seal and unseal the interior space 18 corresponds to the length of the second apertures 56. Thus, the illustrated embodiment requires less than a quarter turn of the rotating part 22 to seal and unseal the interior space 18. Those of ordinary skill in the art will recognize from this disclosure that various embodiments may use more or less rotation to seal and unseal the interior space 18.
Various materials can be used to form the parts discussed herein. These materials include, for example, acrylonitrile butadiene styrene (ABS) styrene-acrylonitrile (SAN) resin, thermoplastic rubber (TPR), polyethylene terephthalate (PET), high impact styrene (HIS), styrene acrylonitrile (SAN), copolyester (PPC), acrylic such as polymethyl methacrylate (PMMA), polycarbonate blends such as styrene maleic anhydride (SMA), clarified polypropylene, polystyrene, and/or silicon. The materials should also be food safe if the container is intended for food.
FIGS. 18 to 20 illustrate a second example embodiment of a food container 10′ in accordance with the present disclosure. The food container 10′ shown in FIGS. 18 to 20 operates generally the same as the food container 10 shown in FIGS. 1 to 17 with minor changes to various parts as shown. It should be understood to those of ordinary skill in the art from this disclosure that parts of the food container 10′ can be added to the food container 10, and vice versa.
As illustrated in FIG. 18, the food container 10′ includes a body 12′ and a lid assembly 14′. The lid assembly 14′ is removeable from the body 12′. The lid assembly 14′ is configured to provide an airtight seal which can be easily sealed and unsealed by a rotational force provided by a user. The food container 10′ also includes a base 70′ that covers the entire bottom wall of the body 12′ in this embodiment.
Like with the first embodiment, the lid assembly 14′ includes a base part 20′, a rotating part 22′, a first slide part 24′, a second slide part 26′, and a sealing part 28′. The base part 20′ and rotating part 22′ have a center axis about which the rotating part 22′ rotates with respect to the base part 20′. In use, the rotating part 22′ rotates around its center axis with respect to the base part 20′ to seal or unseal the interior space 18′ of the body 12′. As with the first embodiment, the rotation of the rotating part 22′ causes the first slide part 24′ and the second slide part 26′ to translate radially in opposite directions with respect to the center axis. The first slide part 24′ and the second slide part 26′ translate with respect to the base part 20′. the rotating part 22′, and the sealing part 28′. During translation in the outward radial direction (away from the central axis), the first slide part 24′ and the second slide part 26′ press the sealing part 28′ into the side wall 16′ of the body 12′, thus sealing the interior space 18′ of the body 12′ with an airtight seal. During translation in the inward radial direction (toward the central axis), the first slide part 24′ and the second slide part 26′ release the pressure pressing the sealing part 28′ into the side wall 16 of the body 12′, thus unsealing the airtight seal provided to interior space 18′ by the lid assembly 14′.
Also like with the first embodiment, the base part 20′ includes at least one protrusion (not shown) that interacts with a first apertures 54′ of the first slide part 24′ or the second slide part 26′ to restrict the first slide part 24′ or the second slide part 26′ to linear radial translation with respect to the center axis. Also, the rotating part 22′ includes at least one protrusion (not shown) that interacts with a second aperture 56′ of the first slide part 24′ or the second slide part 26′ so that rotation of the rotating part 22′ causes the first slide part 24′ or the second slide part 26′ to translate radially with respect to the base part 20′. When the slide part 24′, 26′ translates to seal the interior space (translates leftward in the detailed view of FIG. 19), the outer side surface 58′ of the slide part 24′, 26′ presses the side surface 64′ of the sealing part 28′ into the side walls) 16′ of the body 12′.
FIGS. 18-20 illustrate how the shapes of certain parts can differ in different embodiments. As illustrated, the base part 20′, slide part 24′, 26′ and sealing part 28′ are shaped differently than the corresponding parts of the first embodiment of the food container 10. For example, as seen in FIG. 19, the outer side surface 58′ of the slide part 24′, 26′ is narrower than the outer side surface 58 illustrated in FIG. 17. As another example difference seen in FIG. 18, the sealing part 28′ has an aperture that does not go all the way through the sealing part 28′, compared to the aperture 68 through the top and bottom surfaces of the sealing part 28 as illustrated in FIG. 17. FIGS. 18-20 thus show that variations of the structure shown in FIGS. 1-17 are possible without departing from the spirit and scope of the present disclosure.
FIG. 20A illustrates unsealing of the lid assembly 14′ when the rotating part 22′ is rotated counter-clockwise with respect to the base part 20′. This motion forces the slide parts 24′, 26′ radially inward toward the center axis and away from the sealing part 28′ to release the sealing part 28′ from the side wall(s) 16′ of the body 12′ and thus unseal the interior space 18′. FIG. 20B illustrates sealing of the lid assembly 14′ when the rotating part 22′ is rotated clockwise with respect to the base part 20′. This motion forces the slide parts 24′, 26′ radially outward away from the center axis and toward the sealing part 28′ to press the sealing part 28′ into the side wall(s) 16′ of the body 12′ and thus seal the interior space 18′.
The embodiments described herein provide improved food containers that are durable, provide a reliable seal, and easy to seal and unseal. It should be understood that various chamws and tnodifications to the food containers and correspondin components described herein will be apparent to those skilled in the art and can be made without diminishing the intended advantages.
