Abstract
Abstract A container comprising a wall structure defining an opening and an outwardly projecting bead extending peripherally about the opening is disclosed. A plurality of outwardly projecting vent ribs are provided on the bead. A closure which includes a cover member having a downwardly extending skirt is provided for sealing the container. The downwardly extending skirt has an inner peripheral surface which includes a curved member, for contacting the bead and the plurality of vent ribs, and also a tapered member extending downwardly from the curved member. Upon attachment of the cap to the container, the plurality of vent ribs allow for pressure to be released from the container over the bead and about the plurality of vent ribs, while allowing a sealing engagement of the cap with the closure to resume after relief of the pressure from the container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
250 words
A container having a ventable cap which may be intermittently vented to relieve pressure within the container without loss of seal thereof, said container comprising: an upper peripheral surface defined on said wall structure adjacent the opening of the container; an outwardly projecting bead extending peripherally about said wall structure proximate said upper peripheral surface thereof, said outwardly projecting bead having an outer surface adjacent the opening of the container; at least one vent rib attached to said outer surface of said outwardly projecting bead, said at least one vent rib projecting outwardly therefrom and extending substantially transverse thereto; a closure, including: a cover member for generally covering the opening of the container, said cover member having an upper surface and a lower surface, said lower surface cooperating with said upper peripheral surface for ventable sealing therewith; and a downwardly extending skirt attached to said cover member having an inner peripheral surface, said inner peripheral surface cooperating with both said outer surface of said outwardly projecting bead for ventable sealing therewith and said at least one vent rib for continuous frictional sealing thereat of said container opening; said ventable sealing and continuous frictional sealing comprising sealing means for allowing relief of pressure from the container upon a predetermined pressure being obtained therein about said at least one vent rib and between said outer surface of said outwardly projecting bead and the closure, while allowing resealing after venting with continuous maintenance of engagement of said outwardly projecting bead by said closure.
Claim 2
Dependent Claim
250 words
A container having a ventable cap which may be intermittently vented to relieve pressure within the container without loss of seal thereof, said container comprising: an upper peripheral surface defined on said wall structure adjacent the opening of the container; an outwardly projecting bead extending peripherally about said wall structure proximate said upper peripheral surface thereof, said outwardly projecting bead having an outer surface adjacent the opening of the container; at least one vent rib attached to said outer surface of said outwardly projecting bead, said at least one vent rib projecting outwardly therefrom and extending substantially transverse thereto; a closure, including: a cover member for generally covering the opening of the container, said cover member having an upper surface and a lower surface, said lower surface cooperating with said upper peripheral surface for ventable sealing therewith; and a downwardly extending skirt attached to said cover member having an inner peripheral surface, said inner peripheral surface cooperating with both said outer surface of said outwardly projecting bead for ventable sealing therewith and said at least one vent rib for continuous frictional sealing thereat of said container opening; said ventable sealing and continuous frictional sealing comprising sealing means for allowing relief of pressure from the container upon a predetermined pressure being obtained therein about said at least one vent rib and between said outer surface of said outwardly projecting bead and the closure, while allowing resealing after venting with continuous maintenance of engagement of said outwardly projecting bead by said closure.
Claim 3
Dependent Claim
148 words
A container as defined in claim 1, wherein said closure further comprises said inner peripheral surface defining: a ring portion; a curved portion extending at an incline downwardly from about said ring portion of said downwardly extending skirt, said curved portion being convexly curved away from said ring portion of said downwardly extending skirt, said curved portion terminating at a predetermined position away from said ring portion; and a tapered portion extending downwardly from said curved portion adjacent said predetermined position and about said downwardly extending skirt, said tapered portion being inclined away from said curved portion, such that upon attachment of said closure to the container, said upper peripheral surface of the container cooperates with said lower surface of said cover member to form said ventable seal thereat and said curved portion cooperates with said outwardly projecting bead of the container to form said ventable seal thereat.
Claim 4
Dependent Claim
195 words
A container having an opening for receiving a closure in sealing, ventable contact therewith, the container comprising: a wall structure defining the opening in the container; an upper peripheral surface defined on said wall structure about the opening of the container, said upper peripheral surface cooperating with said closure to form a ventable seal therewith; an outwardly projecting bead extending peripherally about said wall structure proximate said upper peripheral surface thereof, said outwardly projecting bead having an outer surface adjacent the opening of the container for ventable sealing engagement with the closure; and at least one vent rib attached to said outer surface of said outwardly projecting bead, said at least one vent rib projecting generally transversely and outwardly therefrom and being in generally continuous frictional sealing engagement with the closure upon ventable sealing engagement thereof with said outer surface of said outwardly projecting bead for allowing relief of pressure from the container about said at least one vent rib and between said outer surface of said outwardly projecting bead and the closure, while allowing resealing after venting with continuous maintenance of engagement of the closure with said outer surface of said outwardly projecting bead.
Claim 5
Dependent Claim
195 words
A container having an opening for receiving a closure in sealing, ventable contact therewith, the container comprising: a wall structure defining the opening in the container; an upper peripheral surface defined on said wall structure about the opening of the container, said upper peripheral surface cooperating with said closure to form a ventable seal therewith; an outwardly projecting bead extending peripherally about said wall structure proximate said upper peripheral surface thereof, said outwardly projecting bead having an outer surface adjacent the opening of the container for ventable sealing engagement with the closure; and at least one vent rib attached to said outer surface of said outwardly projecting bead, said at least one vent rib projecting generally transversely and outwardly therefrom and being in generally continuous frictional sealing engagement with the closure upon ventable sealing engagement thereof with said outer surface of said outwardly projecting bead for allowing relief of pressure from the container about said at least one vent rib and between said outer surface of said outwardly projecting bead and the closure, while allowing resealing after venting with continuous maintenance of engagement of the closure with said outer surface of said outwardly projecting bead.
Claim 6
Dependent Claim
14 words
A container as defined in claim 3, wherein said wall structure is substantially cylindrical.
