The present disclosure relates to fluid controlling devices and, more particularly, container lids and valves configured to couple to an open top of a fluid supporting container such as a beverage cup to selectively seal fluid within the fluid supporting container.
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.
In comparison, known resealable container lids typically include complex mechanical mechanisms that are often an assembly of several distinct elements. As such, the known resealable container lids can be mechanically complicated, difficult to use, and/or are relatively expensive to manufacture.
An aspect of the present disclosure provides a lid configured for use with a fluid container. The lid includes a body member including an outer periphery configured to couple to a rim of a fluid container. The body member defines a pair of apertures that extend through the body member. The body member may be detachably couplable to the fluid container. A valve operably coupled to an interior/bottom surface of the body member includes a pair of protuberances that are configured to selectively engage the pair of apertures. Each protuberance is in registration with one of the pair of apertures. Depression of one of the protuberances moves the pair of protuberances out of sealed engagement with the pair of apertures for dispensing fluid contained within the fluid container. The pair of protuberances may be in vertical registration with the pair of apertures so as to extend parallel to a longitudinal axis that is defined through the fluid container.
The valve may include a generally elliptical configuration that has side portions at opposite ends of a major axis defined through the valve and top and bottom portions at opposite ends of a minor axis defined through the valve. The side portions of the valve may be configured to flex as a result of depressing one or both of the pair of protuberances to enable the pair of protuberances to be spring loaded and to form a fluid tight seal with surfaces of the body member when the pair of protuberances are positioned within the pair of apertures. The top portion of the valve may be thinner and/or thicker than the bottom portion to provide the valve with a suitable flexibility. In embodiments, the top portion of the valve may be spaced apart from the interior surface of the body member to facilitate a sealed engagement between the pair of protuberances and the apertures when the valve is coupled to the interior surface of the body member. In certain embodiments, the top portion of the valve may be configured to rest on the interior surface of the body member.
A mounting bracket may be operably coupled to the interior surface of the body member. The mounting bracket contacts the bottom portion of the valve to couple the valve to the interior surface of the body member such that both protuberances are depressible for dispensing fluid through one or both of the pair of apertures. Alternatively, the mounting bracket may be operably coupled to the interior surface of the body member and in contact with the bottom portion of the valve to couple the valve to the interior surface of the body member such that one of the protuberances is depressible for dispensing a fluid from the aperture in registration with the other protuberance. The mounting bracket may be mechanically coupled to the lid, for example, via at least one biocompatible adhesive. In embodiments, the mounting bracket may be integrally formed with the body member.
Each of the apertures may be provided in a corresponding recess provided on the body member of each lid. In embodiments, the corresponding recesses and/or apertures are positioned on the body member in a diametrically opposite relationship relative to one another. The corresponding recesses may be configured to receive a corresponding one of the pair of protuberances therein so as to allow depression thereof by the user. The corresponding recesses may have a generally circumferential configuration. Additionally, a generally elongated recess may be provided on the body member and positioned between the pair of corresponding recesses so as to allow stacking of a plurality of lids and to save space. In embodiments, the generally elongated recess is configured to enable adjacently stacked lids to be radially offset, for example, approximately 90 degrees.
According to one aspect, the lid includes a body member including an outer periphery configured to couple to a rim of a fluid container. The body member defines a pair of apertures extending through the body member. The body member may be detachably couplable to the fluid container. A valve operably couples to an interior surface of the body member and includes a pair of depressible protuberances disposed in selective sealed engagement with the pair of apertures so as to prevent dispensing of a fluid from the fluid container. A mounting bracket operably couples to an interior surface of the body member and is configured to couple the valve to the body member. The pair of protuberances is configured such that depression of one of the pair of protuberances moves the pair of protuberances out of sealed engagement with the pair of apertures for dispensing a fluid of the fluid container. Each of the pair of protuberances may be in vertical registration with one of the pair of apertures so as to extend parallel to a longitudinal axis that is defined through the fluid container.
The valve may include a generally elliptical configuration that has side portions at opposite ends of a major axis defined through the valve and top and bottom portions at opposite ends of a minor axis defined through the valve. The side portions of the valve may be configured to flex as a result of depressing one or both of the pair of protuberances to enable the pair of protuberances to be spring loaded and to form a fluid tight seal with surfaces of the body member when the pair of protuberances are positioned within the pair of apertures. The top portion of the valve may be thinner and/or thicker than the bottom portion to provide the valve with a suitable flexibility. In embodiments, the top portion of the valve may be spaced apart from the interior surface of the body member to facilitate a sealed engagement between the pair of protuberances and the apertures when the valve is coupled to the interior surface of the body member. In certain embodiments, the top portion of the valve may be configured to rest on the interior surface of the body member.
A mounting bracket may be operably coupled to the interior surface of the body member and in contacting relationship with the bottom portion of the valve to couple the valve to the interior surface of the body member such that both protuberances are depressible for dispensing a fluid from the aperture in registration with the other protuberance. Alternatively, the mounting bracket may be operably coupled to the interior surface of the body member and in contacting relationship with the bottom portion of the valve to couple the valve to the interior surface of the body member such that one of the protuberances is depressible for dispensing a fluid from the aperture in registration with the other protuberance. The mounting bracket may be coupled to the lid via one or more biocompatible adhesives.
Each of the apertures may be provided in a corresponding recess provided on the body member. The corresponding recesses may be configured to receive a corresponding one of the pair of protuberances therein so as to allow depression thereof by the user. The corresponding recesses may have a generally circumferential configuration. Additionally, a generally elongated recess may be provided on the body member and positioned between the pair of corresponding recesses so as to allow stacking of a plurality of lids.
According to one aspect, the present disclosure relates to a lid configured for use with a fluid container and includes a body member and a valve. The body member includes a central body that extends to an outer periphery configured to couple to a rim of a fluid container. The body member defines an aperture therethrough and has a top surface and a bottom surface.
The valve has a first portion directly secured to the bottom surface of the body member and a second portion that extends from the first portion. The second portion includes a protuberance and is movable relative to the first portion between a free state and a depressed state in response to deflection of at least a portion of the central body of the body member relative to the outer periphery of the body member. The first portion may be disposed transverse to the second portion in at least one of the free state and the depressed state. The first portion may be parallel to the second portion in at least one of the free state and the depressed state.
The protuberance is configured for sealed engagement with the aperture of the body member while the second portion is in the free state. The protuberance is spaced from the aperture of the body member while the second portion is in the depressed state. The protuberance may include a tapered surface. The tapered surface may be disposed in the aperture of the body member while the second portion of the valve is in the free state to seal the aperture. The tapered surface may extend through the aperture of the body member in the free state.
In embodiments, the second portion includes a second protuberance configured to contact the bottom surface of the body member. The deflection of the central body deflects the second protuberance such that the second portion pivots relative to the first portion between the free state and the depressed state.
The bottom surface of the central body may contact a top surface of the second portion of the valve to move the second portion from the free state to the depressed state in response to the deflection of the central body. The bottom surface of the central body may be spaced from the top surface of the second portion while the second portion is in the free state. The bottom surface of the central body may be in contact with the top surface of the second portion while the second portion is in the depressed state.
In embodiments, the central body includes a nub that extends from the top surface of the body member. The nub may be deflectable relative to the central body to move the second portion between the free state and the depressed state.
In some embodiments, the valve includes at least one rib along a portion thereof. The valve may include at least two ribs disposed in parallel relation.
In certain embodiments, the first and second portions of the valve may be connected by a hinged portion. The hinged portion may include at least one bend to orient the second portion relative to the first portion.
In embodiments, the first portion may be heat sealed to the bottom surface of the body member. In some embodiments, the first portion is ultrasonically welded to the bottom surface of the body member.
In one aspect, a valve for a container lid is provided. The valve is adapted to directly secure to a container lid and includes a protuberance, wherein upon securement of the valve to the container lid, the protuberance is configured to selectively disengage from sealed engagement with an aperture defined in the container lid in response to a deflection of a central body of the container lid relative to an outer periphery of the container lid.
The valve may include a first portion and a second portion. The second portion may be movable relative to the first portion and supports the protuberance. In embodiments, the second portion includes a second protuberance configured to contact a bottom surface of the central body of the container lid to enable the second portion to move relative to the first portion. In embodiments, the valve includes at least one rib along a portion thereof. The valve may include a hinged portion that connects the first and second portion. The hinged portion can include at least one bend.
Other aspects, features, and advantages will be apparent from the description, drawings, and the claims
Various embodiments of the present disclosure are described hereinbelow with references to the drawings, wherein:
As used herein, the terms “proximal” or “trailing” refer to the portion of a structure that is closer to a user, while the terms “distal” or “leading” refer to the portion of a structure that is farther from the user.
Fluid container 2 may be made from any suitable material including, but not limited to, plastic, paper, glass, metal, ceramic, closed-cell extruded polystyrene foam, cardboard, etc. Although fluid container 2 may have any suitable configuration, fluid container 2 is shown, for illustrative purposes, as a typical paper/cardboard cup utilized, for example, by most restaurants, coffee houses, etc.
Fluid container 2 includes a generally cylindrical configuration having an open top end 6 and closed bottom end 10 (

Continuing with reference to
A pair of corresponding apertures 26a, 26b (
In accordance with the instant disclosure, body 14 is formed with a thickness of plastic that provides a suitable rigidity to body 14. Specifically, body 14 should have a thickness that prevents substantial deformation thereof when lid 4 is manipulated by a user. More specifically, bottom walls 24a, 24b should be rigid or sturdy enough so as not to deform when protuberances 28a, 28b are in sealed engagement with apertures 26a, 26b. As can be appreciated, if bottom walls 24a, 24b are not sufficiently thick, there exists the likelihood that bottom walls 24a, 24b may deform when protuberances 28a, 28b are in a sealed engagement therewith, which, in turn, may result in a seal between protuberances 28a, 28b and apertures 26a, 26b becoming compromised.
Referring to
In accordance with the instant disclosure, the depressed protuberance provides a vent that facilitates dispensing fluid from lid 4 through the opposing aperture. More particularly, for example, when protuberance 28a is depressed and fluid container 2 is tilted for dispensing fluid through aperture 26b, aperture 26a vents air therethrough, which, in turn, provides a smooth, steady flow of fluid “FL” through aperture 26b and across sidewall 22b of recess 20b (see
Top portion 36a of valve 30 may have any suitable thickness when compared to bottom portion 36b to provide valve 30 with any suitable flexibility sufficient to enable stable movement and selective sealing engagement of the protuberance(s) with the corresponding aperture(s). For example, top portion 36a may be thicker than bottom portion 36b to facilitate movement of protuberances 28a, 28b into and/or out of sealed engagement with apertures 26a, 26b when either of protuberances 28a, 28b is depressed and/or released. In embodiments, top portion 36a is configured to be spaced from interior surface 32 of body member 4 to facilitate a sealed engagement between protuberances 28a, 28b and apertures 26a, 26b when valve 30 is coupled to body 14 (
As discussed above, bottom portion 36b of valve 30 may have any suitable thickness relative to top portion 36a to provide suitable flexibility to valve 30 sufficient to enable stable movement and selective sealing engagement of the protuberance(s) with the corresponding aperture(s). For example, bottom portion 36b may be thinner than top portion 36a to facilitate movement of protuberances 28a, 28b into and/or out of sealed engagement with apertures 26a, 26b when either of protuberances 28a, 28b is depressed and/or released. Specifically, a mounting bracket 40 extends across a medial portion 38 of bottom portion 36b and is utilized to couple valve 30 to interior surface 32 of body 14. In the assembled configuration, medial portion 38 is pressed towards interior surface 32 and forms two bowed portions 37a, 37b that provide a suitable biasing force that is configured to bias protuberances 28a, 28b into sealed engagement with apertures 26a, 26b. In accordance with the instant disclosure, a balance (equilibrium) between a thickness of bottom walls 24a, 24b and a biasing force provided by bowed portions 37a, 37b is needed to ensure that the biasing force of the bottom portion 36b does not deform or otherwise alter the apertures 24a, 24b. As can be appreciated, such a balance may be acquired via rudimentary calculations.
Mounting bracket 40 may take on any suitable configuration to achieve the purposes described herein (
Protuberances 28a, 28b may include any suitable configuration including sides, or portions thereof, that are slanted at any suitable angle and/or sides, or portions thereof, that are not slanted (e.g., perpendicular to body member). As noted above, protuberances 28a, 28b can include a conical configuration to enable spill proof sealing when the sides of the protuberances are positioned in engagement with the surfaces of the lid that define the apertures. As shown in
In the illustrated embodiment, protuberances 28a, 28b have a relatively blunt tip 29a, 29b, see
Protuberances 28a, 28b are configured such that depression of one of the protuberances, e.g., protuberance 28a, moves both of protuberances 28a, 28b out of sealed engagement with apertures 26a, 26b such that fluid “FL” may be dispensed from fluid container 2, see
Operation of fluid container 2 including a lid 4 is described herein. For illustrative purposes, it is assumed fluid “FL” has been previously provided into fluid container 2 and lid 4 is secured thereto to form a seal around fluid container 2. Moreover, it is assumed that protuberances 28a, 28b are oriented parallel to axis “D-D.”
With lid 4 secured to fluid container 2, protuberances 28a, 28b are in sealed engagement with apertures 26a, 26b so as to prevent inadvertent dispensing of the fluid “FL” from fluid container 2. To dispense fluid “FL” contained within fluid container 2, a user may depress one of protuberances 28a, 28b, e.g., protuberance 28b. In doing so, protuberance 28b moves out of sealed engagement with aperture 26b, which, in turn, causes protuberance 28a to move out of engagement with aperture 26a (see
The unique configuration of lid 4 including valve 30 overcomes the aforementioned drawbacks that are typically associated with conventional lids. That is, lid 4 is simple to operate and is relatively inexpensive to manufacture when compared to conventional lids.
From the foregoing and with reference to the various figure drawings, those skilled in the art will appreciate that certain modifications can also be made to the present disclosure without departing from the scope of the same. For example, while lid 4 has been described herein as utilizing valve 30 that includes two protuberances 28a, 28b that may be depressed for dispensing fluid “FL” from fluid container 2, other configurations of valve 30 may also be utilized.
With reference to
Operation of lid 104 is similar to lid 4, unlike lid 4; however, only one of protuberances 128a, 128b is configured to dispense fluid “FL” from the fluid container. Protuberance 128b is configured to dispense fluid “FL” from the fluid container when protuberance 128a is depressed. Depressing protuberance 128b does not cause protuberance 128a to move out of sealed engagement with the corresponding aperture. Therefore, this embodiment only allows dispensing of fluid “FL” on one side only.
In accordance with the present disclosure, embodiments of the valve can be directly coupled to an interior or bottom surface of embodiments of the presently disclosed lids by any suitable fastening technique known in the art, e.g., heat sealing, welding such as ultrasonic welding, adhesive, crimping, snap fit, etc., and/or combinations thereof. In certain embodiments, the valve can be integrally and/or monolithically formed with any one of the presently disclosed lids.
With reference to
Third protuberance 220c of valve 220 is secured to third aperture 210c of body 210, for example, by heat sealing or welding as noted above. When valve 220 is secured to body 210, valve 220 is flexibly biased towards body 210 such that second protuberance 220b of valve 220 engages second aperture 210b of body 210, and first protuberance 220a of valve 220 engages first aperture 210a of body 210. Second protuberance 220b is actuatable, e.g., via depression, to pivot first protuberance 220a about third protuberance 220c, away from first aperture 210a of body 210. In this regard, upon actuation of second protuberance 220b (i.e., when lid 200 is coupled to a fluid retaining cup), valve 220 pivots relative to body 210 so that air can pass into second aperture 210b and fluid retained in the cup can pass out of first aperture 210a.

As seen in
Body member 810 includes a central body 812 that extends to an outer periphery 814 configured to couple to a rim of a fluid container. Body member 810 defines an aperture 816 therethrough and has a top surface 810a and a bottom surface 810b. Central body 812 includes a nub 818 that extends from top surface 810a of body member 810. Nub 818 may be positioned at any suitable location on central body 812 and is configured to move with central body 812. In some embodiments, nub 818 may be deflectable relative to central body 812. In certain embodiments, central body 812 has flat surface devoid of nub 818.
Valve 820 has a first portion 822 directly secured to bottom surface 810b of body member 810 and a second portion 824 that extends from first portion 822 and movable relative to first portion 822 and/or body member 810. In embodiments, first portion 822 may be heat sealed to bottom surface 810b of body member 810. In some embodiments, first portion 822 is ultrasonically welded to bottom surface 810b of body member 810. First and second portions 822, 824 are connected by a hinged portion 823. Hinged portion 823 may include at least one bend 823a to enable second portion 824 to move between a free state (
Second portion 824 of valve 820 includes a ledge 825 that supports a protuberance 824a configured for sealed engagement with aperture 816 of body member 810 in the free state. In the depressed state, protuberance 824a is configured to be spaced from aperture 816 of body member 810. Although shown with an L-shape cross-section, ledge 825 can have any suitable shape and/or dimension. Protuberance 824a includes a tapered surface 824b that is disposed in aperture 816 of body member 810, and extends therethrough, while in the free state to seal aperture 816. A second protuberance 826 of second portion 824 is configured to contact bottom surface 810b of body member 810.
A rib 828 is positioned along at least a portion of valve 820 thereof to increase stiffness of valve 820. Valve 820 may include any number of ribs 828 along any portion thereof (or none at all). For example, valve 820 may include at least two ribs disposed in parallel relation to one another. Two or more ribs may be longitudinally aligned and/or longitudinally offset from one another.
In operation, deflection of central body 812 deflects second protuberance 826 such that second portion 824 pivots relative to first portion 822 between the free state and the depressed state. A bottom surface 812a of central body 812 may contact a top surface 824c of second portion 824 of valve 820 to move second portion 824 from the free state to the depressed state in response to deflection of central body 812. Bottom surface 812a of central body 812 may be spaced from top surface 824c of second portion 824 while second portion 824 is in the free state. Bottom surface 812a of central body 812 may be in contact with top surface 824c of second portion 824 while second portion 824 is in the depressed state. First portion 822 may be disposed transverse to second portion 824 in at least one of the free state and the depressed state. In embodiments, first portion 822 may be parallel to second portion 824 in at least one of the free state and the depressed state.
