- the closure 18 includes a plurality of spaced apart ribs 98 positioned at least partially in the internal closure space 70 .
- the ribs 98 are attached to the upper skirt portion 58 and the top portion 54 , and are configured to increase the rigidity of the closure 18 .
- the rib 98 includes an interiorly facing side 102 , an exteriorly facing side 106 secured to the skirt portion 58 , an upper side 110 secured to the top portion 54 , and a lower side 114 .
- the ribs 98 are interposed between the rim structure 23 and the top portion 54 when the closure 18 is attached to the container 14 , as shown in FIG. 2 .
- ribs 116 are aligned with the blocking structures 90 and 94 , while the remaining ribs 98 are misaligned with the blocking structures 90 and 94 .
- a plane 118 superimposed on the top portion 54 of the closure 18 so as to intersect both the blocking structure 90 and the blocking structure 94 divides the closure into a first closure half portion and a second closure half portion each having an equal number of ribs 98 that are misaligned with the blocking structures 90 and 94 .
- the plane 118 intersects each rib 116 aligned with the blocking structures 90 and 94 .
- the closure 18 includes rib extensions 122 , which are connected to the lower side 114 ( FIG. 3 ) of the ribs 98 .
- Each rib 98 includes an extension 122 .
- the extensions 122 ensure that the closure 18 remains securely connected to the container 14 as the food product within the container is heated.
- the extension 122 includes an exteriorly facing side 126 , an interiorly facing side 130 , and a lower side 134 .
- the interiorly facing side 130 is flush with the interiorly facing side 102 of the rib 98 .
- a plurality of lip spaces 138 is respectively defined between the rib extensions 122 and the skirt 55 .
- Each lip space 138 has a width approximately equal to the distance between the inner surface 46 and the outer surface 50 of the lip 26 , such that the lip may enter the lip space in response to the closure 18 being attached to the container 14 .
- each lip space 138 is configured as a generally U-shaped receptacle formed by the exteriorly facing side 126 of the extension 122 , the lower side 114 of the rib 98 to which the extension 122 is connected, and the interiorly facing side of the skirt 55 .
- the container and closure assembly 10 contains a food product and functions as a receptacle from which a user may consume the food product.
- a user begins by removing the closure 18 from the container 14 .
- the user moves the tab 86 from the relaxed position to the unrelaxed position in the direction of arrow 146 of FIG. 2 .
- the user applies an upward force in the direction of arrow 150 ( FIG. 2 ) to the closure 18 to advance the blocking structure 94 past the lip 26 and to separate the closure from the container 14 .
- the tab 86 returns to the relaxed state after the user releases the force on the tab.
- the user separates the lid 52 from the rim structure 23 by pulling a pull-tab away from the container 14 , as is known to one of ordinary skill in the art. Separation of the lid 52 from the rim structure 23 allows the food product to be withdrawn from the container 14 .
- the user reattaches the closure 18 to the container after removing the lid 52 .
- the user places the closure on the top of the container 14 such that the internal closure space 70 surrounds the rim structure 23 .
- the user applies a downward force (opposite direction of arrow 150 ) to the top portion 54 .
- the downward force causes the blocking structures 90 and 94 to slide along the rim structure 23 and then advance under the lip 26 to their position shown in FIG. 2 . In this position, the bottom surface of each of the blocking structures 90 and 94 face the lip 26 . Also in this position, when the closure 18 is attached to the container 14 , the lip 26 is located in the lip spaces 138 .
- the user then places the container and closure assembly 10 in a microwave oven to heat the food product. During the heating process, the closure 18 is subjected to heat.

Description
- The present disclosure generally relates to assemblies that include a container and a removable closure associated therewith. More specifically, the present disclosure relates to a container and closure assembly having a closure configured to securely engage the container, but be readily removable therefrom.
- Manufacturers commonly package and distribute foodstuffs in assemblies, each of which includes a container and a removable closure. Container and closure assemblies simplify the transportation of packaged foodstuffs, provide surface space for nutritional labeling, and in some instances function as the receptacle from which a user consumes the foodstuff. The assembly includes a generally bowl shaped portion and a removable lid. The bowl portion defines a cavity suitable to contain a quantity of dry, liquid, and/or semi-liquid product. The bowl portion typically has a generally cylindrical shape and a generally flat bottom, which stabilizes the container. The removable lid seals the cavity formed by the bowl portion to preserve the freshness of the food product and to prevent the food product from spilling out of the bowl portion. A user may separate the lid from the bowl portion to expose an opening through which the user may remove the product stored within the container. The removable lid may include a pull-tab or other similar device to assist a user in detaching the lid from the bowl portion. After detaching the lid, a user may place the bowl portion in a microwave oven to heat the product before consumption. Accordingly, the bowl portion may be manufactured from a microwave safe material. In general, users place the closure over the opening formed by the removal of the lid before heating the bowl portion in a microwave oven.
- The container may further include a lip, which defines the opening of the container. The lid and the lip may be an integral structure, which is attached to the bowl portion. Alternatively, the lip may be formed integrally with the bowl portion and the lid may be removably connected to the lip. In each case, the lip remains connected to the bowl portion after the lid has been removed. A user may not reattach the lid to the lip after the user has separated the lid from the lip.
- The closure covers the opening of the container. A user may remove and reattach the closure to the container. During distribution and storage of the container and closure assembly, the closure fits over the lip and the lid. Accordingly, the closure provides a surface upon which a user may stack other container and closure assemblies. During use by a user, the user removes the closure from the container to expose the lid. After the user removes the lid, the user may cover the opening by reattaching the closure to the container. The closure may include vent openings, which enable steam to escape the bowl portion during heating. Additionally, the closure prevents the food product within the bowl portion from splattering out of the container during heating.
- The closure may distort and/or deform during heating of the container filled with food and covered by the closure. In particular, during heating the closure may expand or otherwise change shape, such that the heated closure is no longer adequately attached to the container. What is needed, therefore, is an improved container and closure assembly, which includes a closure that securely attaches to its associated container under various thermal conditions including heating, yet is readily removable therefrom.

The skirt defines an internal closure space and includes (i) a first skirt portion extending downwardly from the periphery, and (ii) a second skirt portion extending downwardly from a first part of the first skirt portion. The second skirt portion includes a first side edge and a second side edge that are spaced apart from each other to form a gap. The first blocking structure is secured to the skirt. The tab extends downwardly from a second part of the first skirt portion and is positioned in the gap. The second blocking structure is secured to the tab. The plurality of spaced apart first ribs is misaligned with the first blocking structure and the second blocking structure. Each rib of the plurality of spaced apart first ribs is (i) positioned in the internal closure space, and is (ii) attached to both the top portion and the skirt. The plurality of spaced apart second ribs is aligned with one of the first blocking structure and the second blocking structure. Each rib of the plurality of spaced apart second ribs is (i) positioned in the internal closure space, and is (ii) attached to both the top portion and the skirt. The first plurality of first rib extensions is (i) secured to a respective one of the plurality of spaced apart first ribs, and is (ii) spaced apart from the skirt. A plurality of first lip spaces is respectively defined between the plurality of first rib extensions and the skirt, and the lip of the container is positioned in each of the first lip spaces when the closure is attached to the container.
- According to another embodiment of the present disclosure, a closure assembly is provided, which is adapted to be attached to a container. The closure assembly includes a top portion defining a periphery, a skirt, a first and second blocking structure, a tab, a plurality of spaced apart first ribs, a plurality of spaced apart second ribs, and a plurality of first rib extensions. The skirt defines an internal closure space and includes (i) a first skirt portion extending downwardly from the periphery, and (ii) a second skirt portion extending downwardly from a first part of the first skirt portion.

FIG. 4 is a perspective view of the bottom side of the closure of the container and closure assembly ofFIG. 1 ; -
FIG. 5 is an elevational view of the bottom side of the closure of the container and closure assembly ofFIG. 1 ; and -
FIG. 6 is a perspective view of another embodiment of a closure that is configured to be used with the container of the container and closure assembly ofFIG. 1 . - According to the present disclosure and referring now to
FIG. 1 , a container andclosure assembly 10 includes acontainer 14 and aclosure 18. Thecontainer 14 is configured to hold a quantity of dry, liquid, and/or semi-liquid product, such as a food product for human consumption. As an example, the food product is chicken noodle soup. Theclosure 18 is configured to attach to thecontainer 14 and be removable therefrom. A user may place the container andclosure assembly 10 in a microwave oven to heat the food product contained within thecontainer 14. Theclosure 18 remains securely attached to thecontainer 14 during the heating process. - As shown in
FIG. 2 , thecontainer 14 includes abody 22 and arim structure 23 that defines alip 26. Thebody 22 has a generally cylindrical shape, which defines acavity 32 suitable to contain a food product or any other solid, liquid, or semi-liquid product. Alternatively, thebody 22 may be configured to have an elliptical, rectangular, or polygonal cross-sectional shape. Thebody 22 has a generally flat bottom portion to stabilize thecontainer 14. The bottom of thebody 22 is closed to contain the food product within thecavity 32. Therim structure 23 is secured to an upper end portion of thebody 22 to define anopening 30 through which thecontainer 14 is filled and emptied. Thelip 26 completely surrounds theopening 30. Thebody 22 may be formed from materials that are conventionally used for the storage and after-purchase heating of food products. For example, thebody 22 is formed from an injection moldable thermoplastic. - The
rim structure 23 is a metallic component that is coupled to thebody 22 in a manner well known to one of ordinary skill in the art. Alternatively, therim structure 23 may be integrally formed with thebody 22 through a thermoplastic molding process so that both thelip 26 and the body collectively define a single polymeric component. - As shown in
FIG. 3 , thelip 26 defines atop surface 38, abottom surface 42 opposed to the top surface, aninner surface 46, and anouter surface 50 opposed to the inner surface. Each of theinner surface 46, theouter surface 50, thetop surface 38, and thebottom surface 42 is configured to interface with a portion of theclosure 18 when the closure is coupled to thecontainer 14. As an alternative, therim structure 23 may have a largely rounded shape without prominent corners to define thesurfaces top surface 38,bottom surface 42,outer surface 50, andinner surface 46 refers to respective top, bottom, inner, and outer portions of therim structure 23 regardless of whether the surfaces are rigidly defined. - The
container 14 includes alid 52, a portion of which is shown inFIG. 2 , that a user may separate from therim structure 23 of thecontainer 14. When thelid 52 is connected to therim structure 23, the lid covers thecavity 32 of thebody 22 and provides an air-tight seal to enable thecontainer 14 to store food products for a substantial period of time without spoiling, as is well known to one of ordinary skill in the art. A score line (not illustrated) may be used between therim structure 23 and thelid 52 to facilitate separation of the lid from therim structure 23 and to allow easy opening and access to the product within thebody 22 of thecontainer 14. Thelid 52 may include a pull-tab (not illustrated) to enable a user to remove the lid from therim structure 23 without an additional tool, such as a can opener. - With reference again to
FIG. 1 , theclosure 18 of the container andclosure assembly 10 surrounds therim structure 23 and the upper portion of thebody 22. A user may detach theclosure 18 from thecontainer 14 to expose thelid 52. After the user removes the lid, the user may reattach theclosure 18 to thecontainer 14, as shown inFIG. 2 . The container and closure assembly 10 (without the lid 52) may be placed in a microwave oven for heating of the food product contained in thecontainer 14. As described below, features of theclosure 18 ensure that the closure remains securely fastened to therim structure 23 of thecontainer 14 during the heating process. - The
closure 18 may be made from materials conventionally used for the storage and after-purchase heating of food products. Exemplary materials for making theclosure 18 include, but are not limited to, polypropylene (“PP”), linear low-density polyethylene (“LLDPE”), and other injection moldable thermoplastics. In one embodiment, theclosure 18 is made from nucleated PP having a density of approximately 0.800 to 1.00 grams per cubic centimeter and a melt index of approximately 50 to 170 grams per 10 minutes. - As shown in
FIG. 1 , theclosure 18 includes atop portion 54 and askirt 55. Theskirt 55 includes anupper skirt portion 58 and alower skirt portion 62. Areference line 64 delineates theupper skirt portion 58 from thelower skirt portion 62. Thetop portion 54 defines a periphery of theclosure 18. Thetop portion 54, as illustrated, defines a circular periphery; however, the top portion may define a periphery of any shape as required by the shape of theopening 30. In one embodiment, thetop portion 54 is generally circular, has a diameter between approximately 9.0 to 12.0 centimeters, and is formed of a material having a thickness of approximately 0.20 to 0.60 millimeters. Thetop portion 54 includes a plurality of vent holes 66 to allow steam to pass through theclosure 18. - The
upper skirt portion 58 extends from the periphery of thetop portion 54 to form a cylindrical structure defining an internal closure space 70 (FIG. 2 ). In a particular embodiment, theupper skirt portion 58 extends downward from thetop portion 54 approximately 0.30 to 0.70 centimeters and has a thickness of approximately 0.4 to 0.8 millimeters. Thelower skirt portion 62 extends downward from a portion of theupper skirt portion 58. In one embodiment, thelower skirt portion 62 extends from theupper skirt portion 58 approximately 0.7 to 1.2 centimeters. As shown inFIG. 1 , thelower skirt portion 62 includes aside edge 74 and aside edge 78 that are spaced apart from each other to form agap 82. When theclosure 18 is connected to thecontainer 14, theouter surface 50 of therim structure 23 faces theskirt 55. - As shown in
FIGS. 1 and 2 , theclosure 18 further includes atab 86, which a user may move or pivot from a relaxed position to an unrelaxed position. When thetab 86 is in the unrelaxed position, a user may easily remove theclosure 18 from thecontainer 14; however, when the tab is in the relaxed position, the closure positively engages thecontainer 14 and a user may not easily remove the closure from the container. Thetab 86 extends downward from a portion of theupper skirt portion 58 and is positioned in thegap 82 between theside edge 74 and theside edge 78 of thelower skirt portion 62, as shown inFIG. 1 . - As shown in
FIGS. 2 and 4 , theclosure 14 includes two blockingstructures closure 18 to thecontainer 14. The blockingstructures structure 90 is connected to an inside surface of thelower skirt portion 62. Theother blocking structure 94 is connected to an inside surface of thetab 86. Both blockingstructures closure 18. As shown inFIG. 3 , when theclosure 18 is attached to thecontainer 14, the blockingstructure 90 contacts thebottom surface 42 of thelip 26 to secure theclosure 18 to thecontainer 14. The blockingstructure 94 engages thelip 26 as shown inFIG. 2 . The blockingstructures bottom surface 42 between approximately 0.8 to 1.5 millimeters. When theclosure 18 is connected to thecontainer 14, thebottom surface 42 faces each of the blockingstructures - As shown in
FIGS. 4 and 5 , theclosure 18 includes a plurality of spaced apartribs 98 positioned at least partially in theinternal closure space 70. Theribs 98 are attached to theupper skirt portion 58 and thetop portion 54, and are configured to increase the rigidity of theclosure 18. As shown inFIG. 3 , therib 98 includes an interiorly facingside 102, an exteriorly facingside 106 secured to theskirt portion 58, anupper side 110 secured to thetop portion 54, and alower side 114. Theribs 98 are interposed between therim structure 23 and thetop portion 54 when theclosure 18 is attached to thecontainer 14, as shown inFIG. 2 . - As shown in
FIG. 5 , theribs 116 are aligned with the blockingstructures ribs 98 are misaligned with the blockingstructures plane 118 superimposed on thetop portion 54 of theclosure 18 so as to intersect both the blockingstructure 90 and the blockingstructure 94, divides the closure into a first closure half portion and a second closure half portion each having an equal number ofribs 98 that are misaligned with the blockingstructures FIG. 5 , theplane 118 intersects eachrib 116 aligned with the blockingstructures - As shown in
FIGS. 2 , 3, and 4, theclosure 18 includesrib extensions 122, which are connected to the lower side 114 (FIG. 3 ) of theribs 98. Eachrib 98 includes anextension 122. Theextensions 122 ensure that theclosure 18 remains securely connected to thecontainer 14 as the food product within the container is heated. As shown inFIG. 3 , theextension 122 includes an exteriorly facingside 126, an interiorly facingside 130, and alower side 134. The interiorly facingside 130 is flush with the interiorly facingside 102 of therib 98. When theclosure 18 is connected to thecontainer 14, thetop surface 38 of therim structure 23 faces each of theribs 98 and theinner surface 46 of thelip 26 faces theextensions 122. - A plurality of
lip spaces 138, one of which is shown inFIG. 3 , is respectively defined between therib extensions 122 and theskirt 55. Eachlip space 138 has a width approximately equal to the distance between theinner surface 46 and theouter surface 50 of thelip 26, such that the lip may enter the lip space in response to theclosure 18 being attached to thecontainer 14. In particular, eachlip space 138 is configured as a generally U-shaped receptacle formed by theexteriorly facing side 126 of theextension 122, thelower side 114 of therib 98 to which theextension 122 is connected, and the interiorly facing side of theskirt 55. When theclosure 18 is connected to thecontainer 14, a portion of eachrib 98 becomes interposed between thelip spaces 138 and thetop portion 54. - In operation, the container and
closure assembly 10 contains a food product and functions as a receptacle from which a user may consume the food product. To prepare the food product for consumption, a user begins by removing theclosure 18 from thecontainer 14. To remove theclosure 18, the user moves thetab 86 from the relaxed position to the unrelaxed position in the direction ofarrow 146 ofFIG. 2 . While holding thetab 86 in the unrelaxed position, the user applies an upward force in the direction of arrow 150 (FIG. 2 ) to theclosure 18 to advance the blockingstructure 94 past thelip 26 and to separate the closure from thecontainer 14. Thetab 86 returns to the relaxed state after the user releases the force on the tab. Next, the user separates thelid 52 from therim structure 23 by pulling a pull-tab away from thecontainer 14, as is known to one of ordinary skill in the art. Separation of thelid 52 from therim structure 23 allows the food product to be withdrawn from thecontainer 14. - If the user desires to heat the food product within the
container 14, the user reattaches theclosure 18 to the container after removing thelid 52. To reattach theclosure 18, the user places the closure on the top of thecontainer 14 such that theinternal closure space 70 surrounds therim structure 23. Next, the user applies a downward force (opposite direction of arrow 150) to thetop portion 54. The downward force causes the blockingstructures rim structure 23 and then advance under thelip 26 to their position shown inFIG. 2 . In this position, the bottom surface of each of the blockingstructures lip 26. Also in this position, when theclosure 18 is attached to thecontainer 14, thelip 26 is located in thelip spaces 138. - Once the user has reattached the
closure 18 to thecontainer 14, the user then places the container andclosure assembly 10 in a microwave oven to heat the food product. During the heating process, theclosure 18 is subjected to heat. Nonetheless, theclosure 18 remains securely attached to thecontainer 14. In particular, even if theclosure 18 exhibits a change in configuration in response to the heat, the closure remains securely connected to thecontainer 14 due to physical interaction of thelip 26, theextensions 122, and/or theskirt 55. - Another embodiment of the
closure 18′ of the container andclosure assembly 10 is illustrated inFIG. 6 . For clarity, like components of theclosure 18 and theclosure 18′ are labeled with like reference numerals except that the embodiment shown inFIG. 6 includes a prime symbol. Theclosure 18′ is configured and operates in the exact same manner as theclosure 18, except that theclosure 18′ does not includeextensions 122′ on theribs 116′ that are aligned with the blockingstructures 90′ and 94′, as shown inFIG. 6 . - Variations and modifications of the present disclosure are possible; however, all variations and modifications, which are obvious to those of ordinary skill in the art to which the present disclosure pertains, are considered to be within the scope of protection granted by this Letters Patent.
