[0001] A lid for a container is provided.BACKGROUND
[0002] Lids are used for containing fluids within containers. Lids can be removably coupled to the container and can be configured to allow fluid to pass from within the container, through the lid, to outside of the container.SUMMARY
[0003] In one aspect, a container lid is provided. In one embodiment, the container lid can include a cylindrical housing configured to releasably couple the lid with a container. The cylindrical housing can include a first end, a second end opposite the first end, an end wall adjacent to the first end extending across the cylindrical housing, and a cavity extending from the end wall toward the second end. The cylindrical housing can further include a spout protruding from the first end and comprising a conduit extending therein. The conduit can include a conduit inlet positioned at a first end of the conduit and a spout outlet at a second end of the conduit. The conduit can be configured to provide a laminar flow of fluid out of the spout outlet.
[0004] In some embodiments, the spout can have a substantially frustoconical shape. In some embodiments, the conduit can extend within the spout at an angle relative to the end wall. In some embodiments, the angle can be between about 10-15 degrees, 15-20 degrees, 20-25 degrees, 25-30 degrees, 30-35 degrees, or 35-40 degrees.

[0027] It is noted that the drawings are not necessarily to scale. The drawings are intended to depict only typical aspects of the subject matter disclosed herein, and therefore should not be considered as limiting the scope of the disclosure.DETAILED DESCRIPTION
[0028] Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
[0029] Various embodiments of lids for use with a container are provided herein. In general, a lid can be releasably coupled to a container having a fluid therein. The fluid can be dispensed from the container via an opening or similar outlet provided in the lid. For example, container lids can include a spout through which a fluid contained within a container can be dispensed from the container. When dispensing a fluid from a container, it can be desirable to dispense the fluid at a consistent flow rate so as to provide a consistent volume for every dispensing action and to avoid spilling the fluid. When considered in the context of beverage containers, it can be desirable for a lid to dispense fluid at a consistent rate and with a uniform volume per drinking action (e.g., taking a sip from the beverage container or pour the fluid from the beverage container) in order to provide a more enjoyable drinking experience to the user and to avoid spilling the fluid on the user. Various embodiments of an improved container lid addressing these problems are provided herein.
[0030] The improved container lids provided herein can releasably couple to a container, such as a container storing or otherwise containing a fluid therein. The container lids described herein can include a spout containing a conduit extending therethrough and having a conduit inlet at a first end of the conduit and a conduit outlet at a second end of the conduit. The conduit can be angled relative to a horizontally-oriented end wall of the container lid so as to advantageously provide a less restrictive flow path of the fluid passing from the container through the spout. For example, when a user lifts the container to place the spout in their mouth, the angled conduit can provide better alignment of the flow path with the user’s mouth to improve the provision of fluid from the spout into the user’s mouth. Additionally, the conduit inlet and the conduit outlet can be sized to further aid fluid distribution from the spout. For example, the container lids described herein can include a conduit inlet having a smaller opening size or area size than the opening size or area size of the conduit outlet. In this way, the pressure of the fluid can increase and the flow rate can be reduced as it exits the conduit outlet since the conduit outlet is advantageously sized to be larger than the conduit inlet. Additionally, the angled conduit can provide the fluid through therethrough with a consistent laminar flow as compared to spout conduit designs of other container lids.
[0031] An embodiment of a beverage container including an improved container lid is illustrated in FIGs. 1A-1B. As shown, a beverage container 100 can include a lid 101 and a body 102 having a cavity 106 therein. A fluid can be contained in the cavity 106. The lid 101 can be releasably coupled to the body 102. For example, the lid 101 can include threaded coupling features 126 (shown in FIG. 4) configured to engage corresponding threaded coupling features arranged on the body 102. In some embodiments, the lid 101 can be coupled to the body using alternate coupling features, such as friction fit features, slot and groove features, detent features, snap fit features, or the like. The lid 101 can include a spout 103. The spout 103 can include a conduit outlet 104 from which fluid stored within the cavity 106 can be dispensed from the lid 101. The lid 101 can also include a lid cap 105. The lid cap 105 can be an actuator that can be mechanically linked to an actuation mechanism configured to allow fluid to exit the conduit outlet 104. For example, the lid cap 105 can include a recess 110 on a top surface 117 of the lid cap 105 as shown in FIG. 2A. A user can depress the recess 110 to cause the actuation mechanism to open a conduit inlet to allow the fluid to enter a conduit extending through the spout 103 to exit from the conduit outlet 104.
[0032] The body 102 can include a cylindrical shape, but other shapes can be envisioned. The body 102 can include an outer shell 107, a liner 108, and an inner shell 109. In some embodiments, the outer shell 107 can include a coating, a material, or surface features configured to enhance gripping or manually holding the body 102, for example to prevent slippage of the body 102 from a user’s hand. In some embodiments, the outer shell 107 can be a metal, plastic, or ceramic material. In some embodiments, the outer shell 107 can include a material configured to thermally insulate the body 102. The liner 108 can include a thermally-insulative material. The inner shell 109 can include a metal, plastic, glass, or ceramic material.
[0033] The lid 101 is shown in additional detail in FIGs. 2A-6C. For example, as shown in FIG. 2A, the lid 101 can include a cylindrical housing 111 extending between a first end 112 and a second end 113. The spout 103 can have a frustoconical shape protruding upward from the fand can extend from a portion of the cylindrical housing 111. In some embodiments, the spout 103 can have other shapes, such as a cylindrical shape, an obelisk shape, a pyramidal shape, or the like. A conduit 129 shown in FIG. 4 can fluidically couple the cavity 106 of the body 102 to the conduit outlet 104.
[0034] As shown in the bottom view of FIG. 2B, the lid 101 can include a cavity 128 extending between the second end 113 and an end wall 119. The cavity 128 can be enclosed at one end via the end wall 119 extending across the cylindrical housing 111. The end wall 119 can be configured in a recess 130 of the cylindrical housing 111 that extends from the first end 112 thereof. The lid 101 can include an actuation mechanism 114 configured to open a flow path through a conduit inlet 125 (shown in FIG. 4) when actuated via the lid cap 105. The actuation mechanism 114 can be coupled to the end cap 105 and to a frame 116. The lid 101 can also include a gasket 115 configured to abut and seal the lid 101 with the body 102.
[0035] As shown in the top view of FIG. 3A, the lid 101 can include attachment features 122A, 122B and a vent actuator 123 configured in the end wall 119. The attachment features 122A, 122B can couple the lid cap 105 to the cylindrical housing 111. For example, as shown in FIG. 3B, the lid cap 105 can include protrusions 120A and 120B extending from a bottom surface 118 of the lid cap 105. The protrusions 120A, 120B can be received in and coupled with the attachment features 122A, 122B to pivotably couple the lid cap 105 to the cylindrical housing 111. The bottom surface 118 of the lid cap 105 can also include a vent actuator housing 121. When the lid cap 105 is coupled to the cylindrical housing 111, the vent actuator 123 can be positioned within the vent actuator housing 121. The vent actuator 123 and the vent actuator housing 121 can be included in the actuation mechanism 114. When the lid cap 105 is depressed downward in direction A, the vent actuator 123 can be configured to open a vent 127 as shown in FIG. 4. This actuation can cause a vent plug 132 to move downward in direction B to open the vent 127 and thereby provide a venting function to reduce air pressure within the body 102. A vent gasket 131 can be provided to engage and seal the vent plug 132 to prevent fluid from exiting the vent 127 when not in use.
[0036] As shown in FIG. 4, the actuation mechanism 114 can also include a linkage 133 coupled to the frame 116 and extending to an inlet plug 134 positioned at the conduit inlet 125. Actuation of the lid cap 105 in direction A can cause the inlet plug 134 to actuate downward in direction C to open the conduit inlet 125. The opening of the conduit inlet 125 can be adjusted via adjustment mechanism 124. For example, the adjustment mechanism 124 can include a rotatable mechanism configured to adjust an amount of downward travel of the inlet plug 134 relative to the conduit inlet 125. Advantageously, a user can manipulate the adjustment mechanism 124 to configure smaller or larger amounts of fluid to be dispensed into the conduit inlet 125. The actuation mechanism 114 can be configured to maintain the inlet plug 134 in a closed position relative to the conduit inlet 125 until a user depresses the lid cap 105.
[0037] As further shown in FIG. 4, the lid 101 can also include a conduit 129. The conduit 129 can be angled relative to the end wall 119 and the wall of the cylindrical housing 111 at the first end 112. The conduit 129 can extend within the spout 103 between the conduit inlet 125 at a first end and a conduit outlet 104 at a second end. In some embodiments, the conduit 129 can have a substantially cylindrical cross-sectional shape. In other embodiments, the conduit 129 can include a substantially oval, rectangular, or square cross-sectional shape. In some embodiments, one or more walls of the conduit 129 can have a linear (or planar) shape. In some embodiments, one or more walls of the conduit 129 can include a non-planar shape, such as a crescent shape, or a semi-circular shape.
[0038] As shown in FIG. 5, the conduit 129 can be configured at an angle α relative to the end wall 119 or a horizontal plane extending across the second end 113 of the lid 101. In some embodiments, the angle α can be between about 10-15 degrees, 15-20 degrees, 20-25 degrees, 25-30 degrees, 30-35 degrees, or 35-40 degrees relative to the end wall 119. Optimally, the angle α can be about 25 degrees. In some embodiments, the angle α can be larger or smaller. In some embodiments, a first conduit wall 135 and / or a second conduit wall 136 can be angled at about 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 degrees relative to the end wall 119. In some embodiments, the first conduit wall 135 and / or the second conduit wall 136 can be angled at larger or smaller angles. In some embodiments, the angle A of the first conduit wall 135 can be greater than the angle B of the second conduit wall 136 or vice versa. In this way, the conduit 129 can increase in volume along its length (e.g., toward the conduit outlet 104) such that the conduit 129 has a tapered shaped between the conduit inlet 125 and the conduit outlet 104. This tapered shape can reduce the pressure of the fluid flowing through the conduit 129 and can improve the laminar flow of the fluid through the conduit 129.
[0039] The area of the conduit inlet 129, the vent 127, and the conduit outlet 104 can be configured to provide an enhanced laminar flow and drinking experience. For example, as shown in FIG. 6A, the conduit outlet 104 can have an area A1 between about 120-125 mm2, 125-130 mm2, 130-135 mm2, 135-140 mm2, 140-145 mm2, 145-150 mm2, 150-155 mm2, 155-160 mm2, 160- 165 mm2, or 165-170 mm2. Optimally, the area A1 of the conduit outlet 104 can be about 150 mm2. In some embodiments, the area A1 of the conduit outlet 104 can be larger or smaller.
[0040] As shown in FIG. 6B, the vent 127 can have an area A2 between about 10-15 mm2, 15-20 mm2, 20-25 mm2, 25-30 mm2, 30-35 mm2, or 35-40 mm2. Optimally, the area A2 of the vent 127 can be about 30 mm2. In some embodiments, the area A2 of the vent 127 can be larger or smaller.
[0041] As shown in FIG. 6C, the conduit inlet 125 can have an area A3 between about 60-65 mm2, 65-70 mm2, 70-75 mm2, 75-80 mm2, or 80-85 mm2. Optimally, the area A3 of the conduit inlet 125 can be about 30 mm2. In some embodiments, the area A3 of the conduit inlet 125 can be larger or smaller.
[0042] In some embodiments, a ratio of the area A1 of the conduit outlet 104 to the area A3 of the conduit inlet 125 can be about 1.5 to 1, 1.6 to 1, 1.7 to 1, 1.8 to 1, 1.9 to 1, 2.0 to 1, 2.1 to 1, 2.2 to 1, 2.3 to 1, 2.4 to 1, or 2.5 to 1. In a preferred embodiment, the ratio of the area A1 of the conduit outlet 104 to the area A3 of the conduit inlet 125 can be about 2 to 1. In some embodiments, the ratio of the area A1 of the conduit outlet 104 to the area A3 of the conduit inlet 125 can be larger or smaller.
[0043] As shown in FIG. 7A, the conduit outlet 104 can have a plurality of outlet walls OW, such as outlet walls OW1-OW4. In some embodiments, one or more of the outlet walls OW can have a linear shape. In some embodiments, one or more of the outlet walls OW can have a curved or non-linear shape. For example, as shown in FIG. 7A, each of the outlet walls OW1-OW4 have a non-linear shape. The conduit outlet 104 can have a length LCO of about 10-20 mm, such as about 10-12 mm, 12-14 mm, 14-16 mm, 16-18 mm, or 18-20 mm. Optimally, the LCO can be about 15.8 mm. Larger or smaller LCO dimensions can be envisioned. The conduit outlet 104 can have a height How of about 5-15 mm, such as about 5-7 mm, 7-9 mm, 9-11 mm, 11-13 mm, or 13-15 mm. Optimally, the How can be about 10.5 mm. Larger or smaller How dimensions can be envisioned.
[0044] As shown in FIG. 7B, the conduit inlet 125 can have a plurality of inlet walls IW, such as inlet walls IW1-IW4. In some embodiments, one or more of the inlet walls IW can have a linear shape. In some embodiments, one or more of the inlet walls IW can have a curved or non-linear shape. For example, as shown in FIG. 7B, each of the inlet walls IW1-IW4 have a non-linear shape. The conduit inlet 125 can have a length LCI of about 10-20 mm, such as about 10-12 mm, 12-14 mm, 14-16 mm, 16-18 mm, or 18-20 mm. Optimally, the LCI can be about 15.5 mm. Larger or smaller LCI dimensions can be envisioned. The conduit inlet 125 can have a height HCI of about 3-9 mm, such as about 3-5 mm, 5-7 mm, or 7-9 mm. Optimally, the HCI can be about 5.6 mm. Larger or smaller HCI dimensions can be envisioned.
[0045] In some embodiments, the conduit 129 can be substantially straight along its length as measured between the conduit inlet 125 and the conduit outlet 104. In some embodiments, the conduit 129 can include one or more segments along its length. The segments can be angled relative to one another and relative to either of the conduit outlet 104 or the conduit inlet 125. For example, as shown in FIG. 8A, the conduit 129 can include a first segment CS1 and a second segment CS2. In some embodiments, the first segment CS1 can extend from the end wall 119 (and the conduit inlet 125) in a substantially vertical orientation. The conduit 129 can then transition to an angled orientation relative to the end wall 119, as shown by the second segment CS2. In some embodiments, the second segment CS2 can be angled relative to the first segment CS1 by a segment angle SA. In some embodiments, the segment angle SA can be about 185-190 degrees, 190-195 degrees, 195-200 degrees, 200-205 degrees, 205-210 degrees, 210-215 degrees, 215-220 degrees, or 220-225 degrees. Optimally, the segment angle SA can be about 207 degrees. Larger or smaller segment angles SA can be envisioned. Although in FIG. 8A, two segments CS of the conduit 129 are shown, in some embodiments, the conduit 129 can include more or less segments CS. For example, the conduit 129 can include one, two, three, four, or five or more segments CS. The angle SA between any two segments CS can vary and need not be limited to the angle SA dimensions described above in relation to CS1 and CS2. The segments CS can be configured at one or more angles SA so as to provide improved flow rate and laminar flow characteristics described herein.
[0046] As shown in FIG. 8B, the outlet walls OW of the conduit outlet 104 can have varying dimensions. For example, the wall thickness WT1 of the outlet wall OW4, as measured between an outer surface 137 of the cylindrical housing 111 and the first conduit wall 135 can be about 1.2-1.4 mm, 1.4-1.6 mm, 1.6-1.8 mm, 1.8-2.0 mm, 2.0-2.2 mm, or 2.2-2.4 mm. Optimally, the OW4 can be about 1.9 mm as shown in FIG. 8B. In some embodiments, the OWs can be more or less than these dimensions. As further shown in FIG. 8B, the wall thickness WT2 of the wall OW1 can be about 1.0-1.2 mm, 1.2-1.4 mm, 1.4-1.6 mm, 1.6-1.8 mm, 1.8-2.0 mm, 2.0-2.2 mm, or 2.2-2.4 mm. Optimally, the OW1 can be about 1.5 mm as shown in FIG. 8B. In some embodiments, the OWs can be more or less than these dimensions.
[0047] The conduit 129 can be enclosed at the conduit outlet 104 via the outlet walls OW, such as OW1-OW4 as described in relation to FIG. 7A. The outlet walls OW can be arranged at an angle relative to the first conduit wall 135 of the conduit 129. For example, as shown in FIG. 9, an inner surface 138 of the outlet wall OW3 can be arranged at an angle β relative to the first conduit wall 135. In some embodiments, the angle β can be between about 20-25 degrees, 25-30 degrees, 30-35 degrees, 35-40 degrees and 40-45 degrees. Optimally, the angle β can be about 29.5 degrees as shown in FIG. 9. In some embodiments, the angle β can be larger or smaller. As further shown in FIG. 9, an outer surface 139 of the outlet wall OW3 can be arranged at an angle β′relative to the first conduit wall 135. In some embodiments, the angle β′can be between about 25-30 degrees, 30-35 degrees, 35-40 degrees, 40-45 degrees, 45-50 degrees, 50-55 degrees and 55-60 degrees. Optimally, the angle β′can be about 46.2 degrees as shown in FIG. 9. In some embodiments, the angle β′can be larger or smaller. In some embodiments, the outlet walls OW can have a rounded or circular profile as shown in FIGs. 8B and 9. In other embodiments, the outlet walls OW can have a planar profile.
[0048] With reference now to FIG. 10, the conduit inlet 125 can be formed by inlet walls IW as described in relation to the description of FIG. 7B. As shown in FIG. 10, the inlet walls IW can have a curved or sloped portions 141 and the length LCI (and height HCI) of the conduit inlet 125 can be measured between end points of the curved or sloped portions 141. For example, the sloped portions 141 of IW1 can be seen extending upward from the conduit inlet 125 toward the second conduit segment CS2. The sloped portions 141 of IW2, IW3, and IW4 can be similarly sloped upward toward the second conduit segment CS2. In this way, the area A3 of the conduit inlet 125 can be less than a cross-sectional area of the conduit 129, such as a cross-sectional area of the second conduit segment CS2 abutting the inlet walls IW1-IW4. The curved or sloped shape of portions 141 of the inlet walls IW can help ensure a fluidic seal is created between the inlet plug 134 and the conduit 129. For example, the inlet plug 134 can include a seat portion 140 and the curved or sloped portions 141 of the inlet walls IW can engage the curved or sloped shape of the seat portion 140 to seal the conduit inlet 125. The sloped portions 141 of the inlet walls IW (such as IW1-IW4) can also serve to constrict the flow of fluid exiting the body 102 into the lid 101, such that the velocity of the fluid can increase simultaneously with a decrease in fluid pressure corresponding to Bernoulli’s principle. As a result, the fluid entering the conduit 129 and thus conveyed to the outlet 104 can achieve greater flow rates compared to conventional lids.
[0049] The container lid 101 described herein can provide enhanced fluid dynamics for dispensing fluid from a container, such as the body 102 shown in FIGs. 1A-1B. For example, as shown in the table of FIG. 11, experimental data associated with the disclosed lid and a sample of conventional lids 1-4 is presented in regard to the mean time to pour or dispense 400 ml of fluid and a maximum flow rate of the dispensed fluid. The results were collected over 3 experimental runs in which the 400 ml was dispensed. As shown, the lid 101 disclosed herein outperformed the conventional lids 1-4 in terms of mean time to pour or dispense 400 ml of fluid and a maximum flow rate of the dispensed fluid. The performance enhancements shown in the table of FIG. 11 can be attributed to the arrangement and dimensions of the conduit 129 within the lid 101, such as angle α, the angle β, the angle β′, the angle SA, as well as the arrangement and dimensions of the conduit outlet 104 outlet walls OW1-OW4, the conduit inlet 125 inlet walls IW1-IW4, the length and cross-sectional area of the conduit 129, the arrangement and dimensions of the conduit segments CS, and the sloped portions 141 of the seat portion 140 of the inlet plug 134. One or more of these features contribute to improved flow rates, consistent volume dispensed per drinking action, and improved laminar flow of fluid dispensed via the spout 103 of lid 101.
