Definitions
- a container such as a cup with a lid selectively mounted to a rim of the cup.
- lift-tabs or the like may be utilized to provide an opening in the lid for dispensing fluid contained within the cup.
- the lift-tab is typically perforated to allow a user to fold the lift-tab and secure the lift-tab to a corresponding protuberance provided on a top surface of the lid.
- one problem associated with the lift-tab type lids is that they are not resealable after having been folded.
- Resealable container lids often include complex mechanical mechanisms that are often an assembly of several distinct elements. Such lids can be mechanically complicated, difficult to use, and/or are relatively expensive to manufacture.
- Resealable container lids having a valve disposed on the underside of a lid are disclosed in U.S. Pat. Nos. 9,296,532 and 9,475,626 which are assigned to the assignee of the present invention. In such disclosures, a portion of the valve is affixed to the underside of the lid.
- a lid for a fluid container includes a body member and a valve member that is adjacent an outer surface of the body member of the lid.
- the body member includes a drinking aperture adjacent to a peripheral edge.
- the drinking aperture is sealed and unsealed via slidable movement of a portion of the valve member between a first sealing orientation in which sealing portion of the valve member occludes the drinking aperture and a drinking orientation in which the valve member does not occlude the drinking aperture.
- sealing and unsealing of the drinking aperture is achieved via slidable movement of a portion of the valve member along a radius that extends through the drinking aperture.
- the valve member includes a first proximal portion that extends from the hinge to a bend or crease and a second valve portion that extends from the first proximal portion to a distal end.
- the second valve portion is slidably movable between the first sealing orientation in which a sealing portion of the second valve portion occludes the drinking aperture and a second drinking orientation in which an opening in the second valve portion is aligned with the drinking aperture to permit fluid flow therethrough.
- sealing and unsealing of the drinking aperture is achieved via slidable lateral movement of a portion of the valve member along an arc that is generally perpendicular to a lid radius that extends through the drinking aperture.
- the valve member is coupled to a peripheral edge of the body member via a hinge.
- the body member, the hinge and the valve member are formed of the same material as an integral, continuous one piece lid.
- At least one pair of opposed inwardly angled retaining members or tabs extend may be provided that project outward from the outer surface of the body member in the embodiment providing for sealing and unsealing via slidable radial movement of a portion of the valve member.
- the retaining members are configured to retain adjacent the outer surface of the body member a guide member formed as a part of the distal end of the valve member while permitting slidable radial movement of the second portion of the valve member.

Abstract
A lid for use with a fluid container includes a body member having an outer surface and a peripheral portion. The body member includes a drinking aperture extending therethrough. The valve member has a first end coupled to the peripheral portion via a hinge. The valve member extends from the hinge to a distal end. The valve member includes a sealing portion, is disposed adjacent the outer surface of the body member and configured to be slidably moveable between a first sealing orientation in which the sealing portion of the valve member substantially occludes the drinking aperture and a second drinking orientation in which the valve member does not occlude the drinking aperture so as to permit fluid flow therethrough. The body member, the hinge, and the valve member may be formed as a continuous one-piece member.
Description
- Not Applicable
- It has long been known in the prior art to enclose a container such as a cup with a lid selectively mounted to a rim of the cup. For example, lift-tabs or the like may be utilized to provide an opening in the lid for dispensing fluid contained within the cup. The lift-tab is typically perforated to allow a user to fold the lift-tab and secure the lift-tab to a corresponding protuberance provided on a top surface of the lid. However, one problem associated with the lift-tab type lids is that they are not resealable after having been folded.
- Resealable container lids often include complex mechanical mechanisms that are often an assembly of several distinct elements. Such lids can be mechanically complicated, difficult to use, and/or are relatively expensive to manufacture.
- Resealable container lids having a valve disposed on the underside of a lid are disclosed in U.S. Pat. Nos. 9,296,532 and 9,475,626 which are assigned to the assignee of the present invention. In such disclosures, a portion of the valve is affixed to the underside of the lid.
- It would be desirable to have a resealable lid that was inexpensive to produce in high volume that avoided complex mechanical mechanisms.
- In accordance with the present invention a lid for a fluid container is disclosed that includes a body member and a valve member that is adjacent an outer surface of the body member of the lid. The body member includes a drinking aperture adjacent to a peripheral edge. The drinking aperture is sealed and unsealed via slidable movement of a portion of the valve member between a first sealing orientation in which sealing portion of the valve member occludes the drinking aperture and a drinking orientation in which the valve member does not occlude the drinking aperture.
- In one embodiment sealing and unsealing of the drinking aperture is achieved via slidable movement of a portion of the valve member along a radius that extends through the drinking aperture. The valve member includes a first proximal portion that extends from the hinge to a bend or crease and a second valve portion that extends from the first proximal portion to a distal end. The second valve portion is slidably movable between the first sealing orientation in which a sealing portion of the second valve portion occludes the drinking aperture and a second drinking orientation in which an opening in the second valve portion is aligned with the drinking aperture to permit fluid flow therethrough.
- In another embodiment sealing and unsealing of the drinking aperture is achieved via slidable lateral movement of a portion of the valve member along an arc that is generally perpendicular to a lid radius that extends through the drinking aperture. The valve member is coupled to a peripheral edge of the body member via a hinge.
- In each embodiment, the body member, the hinge and the valve member are formed of the same material as an integral, continuous one piece lid.
- At least one pair of opposed inwardly angled retaining members or tabs extend may be provided that project outward from the outer surface of the body member in the embodiment providing for sealing and unsealing via slidable radial movement of a portion of the valve member. The retaining members are configured to retain adjacent the outer surface of the body member a guide member formed as a part of the distal end of the valve member while permitting slidable radial movement of the second portion of the valve member.

- More specifically, referring to
FIGS. 1-4 , one embodiment of alid 100 in accordance with the present invention is illustrated and configured for use with afluid container 50. Thelid 100 includes abody member 101 having an outer or upwardly facingsurface 101 a and an opposing inner or containing facingsurface 101 b that faces thefluid container 50 when thelid 100 is mounted thereto. Additionally, thebody member 101 has acentral body 102 and aperipheral portion 104 in the illustrated embodiment is a generally ring-shaped region that surrounds thecentral body 102. Thebody member 101 has a lower circumferentialperipheral edge 103 that generally defines a first plane. Theperipheral portion 104 includes a raisedportion 104 a that extends above thecentral body 102. Theperipheral portion 104 also includes anside edge portion 104 b. The inner surface of theperipheral portion 104 has a generally concave circumferentiallower edge portion 104 c that is configured to sealably couple to arim 52 of thefluid container 50 when the lower circumferentialperipheral edge 103 is urged over therim 52 of thefluid container 50. - The
peripheral portion 104 includes adrinking aperture 106 extending through the raisedportion 104 a which serves as a drinking orifice. Avalve member 108 is formed as a continuous integral unitary member with thebody member 101 from a deformable material as illustrated inFIG. 1 . - The
valve member 108 includes a first proximal portion orarm portion 108 a and a second distal portion orsecond valve portion 108 b. The firstproximal portion 108 a extends from a self-hinge 108 c to a crease or bend 108 d. The term self-hinge, as used herein, is used to refer to a structure that is bendable so as to perform a hinge function and that is integrally formed as a one piece continuous structure and of the same material with members connected to both sides of the hinge. The seconddistal portion 108 b extends from the crease or bend 108 d to adistal end 108 e. The seconddistal portion 108 b includes a sealingportion 108 f and a valve member aperture or valve member opening 108 g that extends through the seconddistal portion 108 b. The sealingportion 108 f in the illustrated embodiment is a protuberance that is cooperative with thedrinking aperture 106 when disposed in a sealing orientation to substantially seal thedrinking aperture 106 as discussed in greater detail below. - The
valve member 108 is formed as a single continuous integral unitary member with thebody member 101 from a deformable material. Thevalve member 108 is foldable with respect to thebody member 101 at the self-hinge 108 c. When folded at the self-hinge 108 c, the firstproximal portion 108 a may confront an outer edge of theperipheral portion 104 when thesecond valve portion 108 b is in the first sealing orientation as shown inFIGS. 2 and 3 . - The sealing
portion 108 f and thevalve member aperture 108 g are spaced apart by a predetermined distance. In the embodiment illustrated inFIGS. 1-4 , thevalve member aperture 108 g is located more proximate to thedistal end 108 e of thevalve member 108 than the sealingportion 108 f In an alternative embodiment, the locations of the sealingportion 108 f and thevalve member aperture 108 g are reversed so that the sealingportion 108 f is more proximate thedistal end 108 e of thevalve member 108. - The second distal or
valve portion 108 b of thevalve member 108 is slidably movable radially over the raisedportion 104 a between a first sealing orientation as shown inFIG. 3 and a second drinking orientation shown inFIG. 4 generally along a longitudinal axis that is generally parallel to the first plane. More specifically, thesecond valve portion 108 b is slidably movable in first and second opposing directions generally along a longitudinal axis that is generally parallel to the first plane and generally parallel to a radial axis through thedrinking aperture 106 to cause the sealingportion 108 f to assume the first sealing orientation and the second drinking orientation, respectively. In the first sealing orientation shown inFIG. 3 , the sealingportion 108 f extends into and occludes thedrinking aperture 106 to substantially seal thedrinking aperture 106 and avoid the flow of liquid therethrough. In an alternative embodiment, the sealing portion comprises a substantially flat surface that occludes thedrinking aperture 106 when aligned therewith. While the illustrated embodiment includes a recessedcentral body 102 andperipheral portion 104 extending above the central body, the configuration of thebody member 101 may be varied without departing from the inventive concepts disclosed herein. By way of example, and not limitation, thebody member 101 may alternatively have a generally planar upper surface, include a raised drinking spout as subsequently discussed and/or include other upper surface configurations consistent with the provision of the sealing and unsealing functions for the drinking aperture as herein described. - The second
distal portion 108 b of thevalve member 108 may be urged outward by exertion of manual pressure at thedistal end 108 e, which is provided as a turned down portion or flange. Urging of the seconddistal portion 108 b of thevalve member 108 radially outward from the position illustrated inFIG. 3 causes the seconddistal portion 108 b to slidably move to the second drinking orientation illustrated inFIG. 4 . When the seconddistal portion 108 b of thevalve member 108 is disposed in the second drinking orientation, thedrinking aperture 106 and thevalve member aperture 108 g are generally aligned so as to permit the flow of liquid through the aligned valve member aperture or opening 108 g and thedrinking aperture 106. - The second distal or
valve portion 108 b may be configured to releasably secure thesecond valve portion 108 b in at least one of the first sealing orientation and the second drinking orientation. More specifically, based on the angles, configuration or shapes selected for the confronting edges of the raisedportion 104 a and the sealingportion 108 f, thesecond valve portion 108 b may be releasably secured in the second drinking orientation with the raisedportion 104 a disposed between thedistal end 108 e of the seconddistal portion 108 b and a confronting edge of the sealingportion 108 f More specifically, based on the cooperative angles, configuration or shapes selected for the confronting edges of the protuberance forming the sealingportion 108 f and the outer edge of the raisedportion 104 a, the second distal orvalve portion 108 b may be lockable or temporarily securable in the second drinking orientation or not lockable or temporarily securable in such orientation. If designed so as not to be releasably lockable or securable in the second drinking orientation, the user will need to maintain manually applied pressure to thedistal end 108 e of the seconddistal portion 108 b to maintain the seconddistal portion 108 b in the second drinking orientation. In the illustrated embodiment, when in the first sealing orientation, the firstproximal portion 108 a generally confronts the side of theperipheral portion 104 as illustrated inFIGS. 2 and 3 . It should be recognized that based on the relative positions of the sealing portion and the opening 108 g in thesecond valve portion 108 b, the firstproximal portion 108 a may be disposed in generally confronting relation with the peripheralouter edge 104 of thebody member 101 when thesecond valve portion 108 b is disposed in the first sealing orientation or the second drinking orientation. - When the
valve member 108 is disposed in the first sealing orientation, the protuberance forming the sealing portion 110 at least partially extends into thedrinking aperture 106 and is cooperative with thedrinking aperture 106 to releasably secures or maintains thevalve member 108 in the first sealing orientation when the protuberance is aligned with thedrinking aperture 106. Although depicted inFIGS. 1-4 as a protuberance that at least partially extends into the drinking aperture when thesecond valve portion 108 b is in the sealing orientation, in another embodiment, the sealingportion 108 f may comprise a generally flat portion of thesecond valve portion 108 b. - Additionally, while the valve member is illustrated as being designed so that the resilient self-hinge urges the first
proximal portion 108 a of thevalve member 108 to confront or be urged toward the outer periphery of thebody member 101, for example, as shown inFIG. 3 , it should be appreciated that alternatively, the self-hinge in the variously disclosed embodiments involving slidable displacement of the valve member along a radius of the body member for sealing and unsealing the drinking aperture may be configured and sprung so as to cause the first proximal portion to be spaced from the outer periphery of the lid as illustrated inFIG. 4 , in which event, a user of the lid would need to urge the first proximal portion radially inward to cause the valve member to change orientations. -
FIG. 5 illustrates an alternative embodiment of alid 200 which is similar in many respects to the lid illustrated inFIGS. 1-4 but which includes a different valve configuration from that illustrated inFIGS. 1-4 . The embodiment illustrated inFIG. 5 , includes abody member 201 having an upper surface 201 a and an inner or fluidcontainer facing surface 201 b. Thebody member 201 further includes a central body portion 202 that is surrounded by anouter periphery 204 having a raisedportion 204 a that includes adrinking aperture 206. Thelid 200 includes avalve member 208 having a first proximal portion orarm portion 208 a and a second distal portion orvalve portion 208 b. In theFIG. 5 embodiment the seconddistal portion 208 b of thevalve member 208 is substantially planar along a length thereof. The firstproximal portion 208 a extends from a self-hinge 208 c to a crease or bend 208 d and, as illustrated in exemplaryFIG. 5 generally confronts an outer edge of theouter periphery 204 of thebody member 201 when the valve member is positioned in a first sealing orientation. The seconddistal portion 208 b extends from the crease or bend 208 d to adistal end 208 e. The seconddistal portion 208 b includes a sealingportion 208 f which is a substantially planar portion of the seconddistal portion 208 b and avalve member aperture 208 g spaced therefrom. Thevalve member aperture 208 g is more proximate to thedistal end 208 e than the sealingportion 208 f In an alternative embodiment, the positions of the sealingportion 208 f and thevalve member aperture 208 g are reversed. - The second
distal portion 208 b is slidably movable along a radius of thebody member 201 between the first sealing orientation as shown inFIG. 5 and a second drinking orientation in which thevalve member aperture 208 g generally aligns with thedrinking aperture 206 by reason of the pliant and bendable nature of the self-hinge 208 c. In the absence of applied manual pressure to thedistal end 208 e, the seconddistal portion 208 b assumes the first sealing orientation illustrated inFIG. 5 self-hinge act like a spring to urge the seconddistal portion 208 b to assume the first sealing orientation illustrated inFIG. 5 . In other respects, the construction of the embodiment ofFIG. 5 is substantially similar to the embodiment illustrated inFIGS. 1-4 . -
FIG. 6 illustrates another embodiment of alid 300 having abody member 301 having an upperbody member surface 301 a and an inner body member surface or fluidcontainer facing surface 301 b. Thebody member 301 has acentral body portion 302 surrounded by anouter periphery 304. Thebody member 301 includes a raisedportion 304 a that extends above thecentral body portion 302 and which includes an upwardly extendingdrinking spout 304 b that extends outward to a tip defining adrinking aperture 306. Thelid 300 further includes avalve member 308 having a first proximal portion orfirst arm 308 a and a second distal portion orvalve portion 308 b. The seconddistal portion 308 b is substantially planar along a portion of the length thereof. The firstproximal portion 308 a connects to thebody member 301 via a self-hinge 308 c. The firstproximal portion 308 a extends from the self-hinge 308 c to a crease or bend 308 d. The seconddistal portion 308 b extends from the crease or bend 308 d to adistal end 308 e. The seconddistal portion 308 b includes a sealingportion 308 f and avalve member aperture 308 g spaced therefrom. Though depicted as a generally flat sealing portion inFIG. 6 , the sealing portion for sealing thedrinking aperture 306 of thedrinking spout 304 b may alternatively be a protuberance that at least partially extends into thedrinking aperture 306 when the second valve portion is in the first sealing orientation, or a protuberance that extends away from the drinking aperture and that forms a recess within the protuberance, wherein at least the tip of thedrinking spout 304 b extends into the recess of the protuberance when thesecond valve portion 308 b is in the first sealing orientation. - The second
distal portion 308 b is slidably movable along a radius of thebody member 301 that extends through thedrinking aperture 306 between a first sealing orientation, shown inFIG. 6 , and a second drinking orientation in which thevalve member aperture 308 g generally aligns with thedrinking aperture 306. In the absence of applied manual pressure to thedistal end 308 e urging the seconddistal portion 308 b in a direction radially outward from the center of thebody member 301, the seconddistal portion 308 b assumes the first sealing orientation illustrated inFIG. 6 with the sealingportion 308 f substantially occluding thedrinking aperture 306 formed in thedrinking spout 304 b. In an alternative embodiment, the positions of the sealingportion 308 f and thevalve member aperture 308 g may be reversed, in which case, urging of the seconddistal portion 308 b of thevalve member 308 radially outward would cause thevalve member 308 to assume the first sealing orientation with the sealingportion 308 f occluding thedrinking aperture 306. -
FIG. 7 illustrates an embodiment of a portion of alid 300′ in accordance with the present invention in which avalve member 308′ is normally open. - The
valve member 308′ includes a first proximal portion orarm portion 308 a′ and a second distal portion orvalve portion 308 b′ as shown. The seconddistal portion 308 b′ includes a sealingportion 308 f′ and avalve member aperture 308 g′ that extends through the seconddistal portion 308 b′. The embodiment ofFIG. 7 generally corresponds to the embodiment ofFIG. 6 noting, however, that the location of thevalve member aperture 308 g′ and the sealingportion 308 f′ have been reversed. Additionally, as illustrated inFIG. 7 , the sealingportion 308 f′ is provided in the form of a protuberance. In an alternative embodiment, the sealingportion 308 f′ may comprise a flat portion of the seconddistal portion 308 b′. The seconddistal portion 308 b′ is slidably movable between a first drinking orientation as shown inFIG. 7 in which thevalve member aperture 308 g′ aligns with thedrinking aperture 306′ and a second sealing orientation in which the sealingportion 308 f′ substantially occludes thedrinking aperture 306′. More specifically, upon the application of a manual outwardly applied force to thedistal end 308 e′ of the valve member, the seconddistal portion 308 b′ slidably moves to the first sealing orientation in which the sealingportion 308 f′ occludes thedrinking aperture 306′. - Based on the depth that the sealing
portion 308 f′ protuberance extends into thedrinking aperture 306′, this embodiment can provide for thevalve member 308′ to remain releasably secured in the sealed orientation. If the protuberance only extends slightly into thedrinking aperture 306′, thevalve member 308′ will return to the first drinking orientation in the absence of pressure applied to thedistal end 308 e′ of thevalve member 308′. The angles, shapes and configuration associated with the confronting edges of the protuberance forming the sealingportion 308 f ‘and the drinking aperture 306’ may be selected to facilitate locking of the valve member in the sealed orientation in some embodiments. The self-hinge 308 c′ serves as a spring-like member as previously discussed to normally urge the seconddistal portion 308 b′ to assume the drinking orientation illustrated inFIG. 7 . -
FIG. 8 is another embodiment which is similar to the embodiment ofFIG. 6 , however, only the sealingportion 908 f of the seconddistal portion 908 b of thevalve member 908 makes contact with the surface of the body member when in the first sealing orientation. Additionally, in the embodiment illustrated inFIG. 8 , the sealingportion 908 f comprises a protuberance that extends into the drinking aperture to occlude the aperture in the first sealing orientation. -
FIG. 9 illustrates another embodiment of a portion of alid 400 that includes a body member andvalve member 408 formed as a continuous integral unitary structure and interconnected by ahinge 408 c. Thevalve member 408 includes a first proximal portion orarm portion 408 a and a second distal portion orvalve portion 408 b. The firstproximal portion 408 a extends from the self-hinge 408 c to a crease or bend 408 d and the seconddistal portion 408 b extends from the crease or bend 408 d to adistal end 408 e. The seconddistal portion 408 b includes a sealingportion 408 f and a valve member aperture or opening 408 g through the seconddistal portion 408 b. The firstproximal portion 408 a is substantially straight and planar along its length. Alternatively, the firstproximal portion 408 a may be provided with a curved shape to achieve desired spring-like characteristics to urge thevalve member 408 to the first sealing orientation depicted inFIG. 9 . - To achieve desired resilience and spring characteristics for the self-hinge and valve member in the various embodiments, the thickness of the deformable material may be selectively varied in the area of the self-hinge and along portions of the first proximal portion of the valve member. By way of example and not limitation, the self-hinge and selected portions of the valve member, including the first proximal portion and the second distal portion of the valve member may be made thicker or thinner than the body member of the lid and thicker or thinner than other portions of the first proximal portion and the second distal portion of the valve to achieve desired resilience, stiffness and spring characteristics for the valve member.
-
FIGS. 10 and 11 illustrate another embodiment of alid 500 having acentral body portion 502 and anouter periphery 504 having adrinking spout 506 defining and terminating at adrinking aperture 506 a. Thelid 500 further includes avalve member 508 formed as a continuous integral unitary structure with theouter periphery 504 of thelid 500. Thevalve member 508 includes a first proximal portion orfirst arm 508 a and a second distal portion orsecond valve portion 508 b. A self-hinge 508 c couples the firstproximal portion 508 a to theouter periphery 504 of thelid 500. The firstproximal portion 508 a extends from the self-hinge 508 c to a crease or bend 508 d and the seconddistal portion 508 b extends from the crease or bend 508 d to adistal end 508 e. The seconddistal portion 508 b includes a sealingportion 508 f that may comprise a protuberance that extends downward from the seconddistal portion 508 b. The sealingportion 508 f is cooperative with thedrinking aperture 506 a to occlude thedrinking aperture 506 a and thereby substantially seal theaperture 506 a when sealingportion 508 f is vertically aligned with thedrinking aperture 506 a. The sealingportion 508 f may extend into thedrinking aperture 506 a and thereby more securely maintain thevalve member 508 in the sealing orientation when the sealingportion 508 f is aligned with thedrinking aperture 506 a. The firstproximal portion 508 a may have substantially straight edges along its length or be provided with a curved or other suitable shape to provide desired spring-like characteristics to normally urge the sealingportion 508 f into alignment with thedrinking aperture 506 a to substantially seal thedrinking aperture 506 a. - The
second valve portion 508 b is slidably movable laterally (i.e. sideways) to seal and unseal thedrinking aperture 506 a.
