Description

RELATED APPLICATION DATA

The present application claims priority to U.S. Provisional Application Ser. No. 63/192,022 filed May 23, 2021 and U.S. Provisional Application Ser. No. 63/218,301, filed Jul. 3, 2021. Each of said applications are incorporated by reference as if set forth fully herein.

FIELD OF THE INVENTION

The present invention relates to liquid containers.

BACKGROUND OF THE INVENTION

Various containers are known for containing liquids or fluids. Some of these containers are designed to allow a user to drink the liquid from the container. Such containers may comprise, for example, bottles, cans and cups.
One common drink container is a cup. Cups may have different shapes and sizes, but they generally share the feature of an open top. A problem with this configuration is that the liquid contained in the cup can easily spill out of the cup, such as if the cup is tipped over or if force is applied to the cup (such as if the cup bounces).
In order to maintain the liquid in a cup, a lid may be located at the top of the cup. However, in order to allow a user to still access the liquid in the cup without removing the lid (such as to drink the liquid or pour it from the cup), the lid must include one or more openings. These openings, however, also then present locations where the liquid may again undesirably escape from the cup.
For example, FIG. 1 is a cross-sectional view of a common disposable cup lid L for use with a disposable cup C. The cup lid L is configured to be connected to a top rim of the cup C and to generally close the top of the cup. However, the cup lid includes a drink opening O through which a user may drink liquid from the cup.
As shown in FIG. 1, a problem with this design is that if a force is applied to the cup, the fluid F in the cup will move within the cup C and can simply flow directly out of the drink opening O. Thus, fluid F may unintentionally flow through the lid L and out of the cup C (e.g. a “spill”).
Many attempts have been made at addressing this problem.
First, the lid can be created with an opening which accepts a straw. This requires that the user have or be supplied with a straw. Further, many users do not like to drink through a straw, particularly when the drink is a hot drink.
Another common solution is to provide a removable stopper. The stopper may be located in the drink opening to block or close the opening. The problem is that the stopper has to be removed and replaced each time the user wishes to dispense liquid through the drink opening. In the case of a vendor providing the cup and lid, the vendor then also has to stock and supply stoppers to their customers, at increased cost. The user can also lose the stopper.
Other lids have been designed with an openable and closeable flap. The flap may comprise a portion of the lid which can be moved between open and closed positions. The flapper avoids the need for a separate stopper, but still suffers from the drawback that the user must open the flap in order to access the drink opening and to re-close the flap in order to close the drink opening thereafter.
Accordingly, a need exists to provide an improved liquid dispensing container, and particular, an improved disposable lid for a cup, such as a disposable cup, which lid is spill-preventing.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.
One embodiment of the invention is a container having spill-prevention technology. In one embodiment, the container is a cup having a lid, where the spill-prevention technology is associated with the lid. In one embodiment, the spill-preventing technology comprises at least one fluid energy dissipating and/or diverting element. The at least one fluid energy dissipating and/or diverting element may comprise at least one baffle, where the baffle is associated with, such as by being located adjacent to, a drink opening of the lid.
Container
One embodiment of the invention will be described with reference first to FIG. 2. FIG. 2 illustrates a container 20. In one embodiment, the container 20 is configured as a cup 22, such as by having a body which is defined by a bottom 24 and an upwardly extending sidewall 26. The bottom 24 may be generally planar. The sidewall 26 preferably extends upwardly from the bottom 24 vertically or generally vertically (such as by having a negative draft moving away from the bottom 24).
In one embodiment, the cup 22 may be generally cylindrical in shape, having a generally circular cross-sectional shape, The bottom 24 may thus be generally circular and the sidewall 26 may be generally cylindrical.
In one embodiment, the top of the sidewall 26 comprises or defines a rim 28. The rim 28 might define a lip or otherwise comprise an area of increased cross-sectional area as compared to the remainder of the wall. For example, the rim 28 might define a lip or bead which is generally circular in cross-sectional shape. The rim 28 defines a generally open top 30 of the cup 22, the open top 30 being generally opposite the bottom 24.
In one embodiment, the container 20 may be disposable, such as constructed from paper stock, plastic, Styrofoam or the like. However, the container 20 could be constructed from other materials, such as plastic, metal (aluminum), glass, etc.
It is noted that while the container 20 preferably comprises a cup 22, the container could have other configurations. For example, the container 20 could be constructed as a generally cylindrical can, such as is common for the configuration of pop/soda containers.
In one embodiment, the container 20 has a top. The top could be integral to the body, or be connected thereto. For example, when the container 20 is configured as a can, the top of the container may be integral (such as by being physically and essentially permanently joined to the sidewall of the container during the manufacturing process).
In a preferred embodiment, the top comprises a removable lid 100. In a configuration where the container 20 is designed to be disposable, so may be the lid 100, such as by being constructed of plastic or a similar material.
One embodiment, of a lid 100 of the invention will be described with reference to FIG. 3. The lid 100 preferably comprise a body having a top 102, a generally opposing bottom 104, and a peripheral edge 106. In a preferred embodiment, the lid 100 may generally have a front 108, a rear 110 and a pair of opposing sides 112,114, in reference to a lid 100 having features as described below.
The lid 100 is preferably configured to engage the cup 22, such as the rim 28, and generally close the open top 30 thereof. In one embodiment, the lid 100 is selectively connectable to the cup 22, thus allowing the lid 100 to be connected to or removed from the cup 22.
In one embodiment, the lid 100 is configured to engage the rim 28 of the cup 22. In one embodiment, the peripheral edge 106 of the lid 100 defines a rim-accepting flange 116. This flange 116 is designed to extend over and capture the rim 28 of the cup 22. Preferably, the flange 116 can flex, thus allowing at least a portion thereof to move outwardly over the rim 28 and then bias or flex back inwardly to capture the rim 28, thus securing the lid 100 to the cup 22. In one embodiment, a bottom of the flange 106 may define a lower edge of the bottom 104 of the lid 100.
In one embodiment, the lid 100 may define or comprise a raised area 120. The raised area 120 preferably extends upwardly above one or more other portions of the lid 100, such as the peripheral edge 106. In one embodiment, at least a portion of the raised area 120 is located adjacent to the peripheral edge 106. As best illustrated in FIG. 3C, the raised area 120 need not have the same elevation in all areas. For example, a highest elevation of the raised area 120 may be located at the front 108 of the lid 100.
As illustrated in FIG. 3D, this design causes the lid 100 to have a central section 124 which is generally planar, a raised area 120 around the central section 124, and then a downwardly extending flange 116, which flange 116 extends below the central section 124.
The lid 100 preferably comprises at least one drink opening 122 (while one is preferred, the lid 100 could have more than one). In a preferred embodiment, the drink opening 122 is associated with the raised area 120, such as by being defined through a top of the raised area. As illustrated, the drink opening 122 may be located at the front 108 of the lid 100.
The shape of the drink opening 122 may vary. In one embodiment, the drink opening 122 is longer (in the side 112 to side 114) direction than it is wide (in the front 108 to back 110 direction). In one embodiment, the drink opening 122 may be generally oval in shape.
Spill Prevention Technology
Most importantly, the container 20 has spill prevention technology. Preferably this technology is associated with the top of the container 20. In the case of the container 20 which comprises a cup 22 having a lid 100, the spill prevention technology is associated with the lid 100. In one embodiment, the spill prevention technology comprises a baffle 200. The baffle 200 is configured to dissipate fluid energy and/or to divert or redirect fluid.
One embodiment of a fluid dissipation and diversion element is illustrated in FIGS. 3E and 3F. In one embodiment, the baffle 200 extends downwardly from the bottom of the lid 100 at, or adjacent to, the drink opening 122. In the illustrated embodiment, the baffle 200 comprise a body or wall 202 that extends downwardly from the lid 100 at the drink opening 122. In one embodiment, the baffle 200 has a first or top end and a second or bottom end 206, and defines a passage 204. In one embodiment, the top end of the baffle 200 is located at the drink opening 122, such that the passage 204 leads to or forms and extension of the drink opening 122, in a downward direction.
When the drink opening 122 is generally oval in shape, the wall 202 may have generally the same peripheral shape and the passage 204 defined thereby may be similar in shape. However, in other embodiments, the baffle 200, including the wall 202 and passage 204, may have shapes which differ from that of the drink opening 122.
In one embodiment, the wall 202 extends downwardly from the bottom 104 of the lid 100 at the drink opening 122 generally parallel thereto. In one embodiment, as described in more detail below, the wall 202 is preferably formed in a molding process with the lid 100, such that the wall 202 comprises the same material as the lid 100 and is contiguous with the body of the lid 100 (for example, by press or compression molding a flat piece of stock (such as plastic) or by injection molding).
In one embodiment (such as where, as illustrated, the baffle 200 is not circular in cross-sectional shape), the baffle 200 may have different sides or wall portions, such as a front and back and a pair of opposing sides. One or more portions of the wall 202 may extend downwardly from the lid 100 different distances than other portions. For example, in the preferred embodiment, a rear portion (closest to the rear 110 of the lid 100) may extend downwardly further than a front portion (closest to the front 108 of the lid).
In one embodiment, the baffle 200 has a bottom or bottom end 206. The bottom end 206 is preferably generally closed. When one or more portions of the wall 202 extend downwardly different distances, the bottom end 206 may be tilted (e.g. not lie in a horizontal plane or a plane which is parallel to the bottom edge of the lid 100). For example, in the preferred embodiment where the rear of the wall 202 extends downwardly further than the front, the bottom end 206 may tilt upwardly moving from the rear 110 of the lid 100 towards the front 108
In one embodiment, one or more openings 210 (which may be referred to as “flow openings”) are provided for allowing fluid to pass through the baffle 200 to the drink opening 122. In one embodiment, one or more perforations or apertures are defined in the baffle 200 and allow fluid to flow from the container 20 and through the baffle 200 into the passage 204 and thereon to the drink opening 122.
As illustrated in FIGS. 3B, 3E and 3F, the one or more openings 210 are provided in the bottom 206 of the baffle 200. The openings 210 might have various shapes and sizes. In a preferred embodiment, the openings 210 may themselves be elongate or oblong. In one embodiment, the passage 204 is about 16 mm long and 6.88 mm wide. In one embodiment, the openings 210 are about 3.48 mm long and 1.5 mm wide, and four openings 210 are provided, spaced from one another by about 1.5 mm. Of course, the size and shape of the openings 210 may depend upon the size and shape of the baffle 200, including the bottom 206 thereof. In general, however, the openings 210 are preferably relatively small in dimension (in relation to the passage 204 and/or drink opening 122) in order to reduce the flow of fluid therethrough.
In one embodiment, the length of the baffle 200 (e.g. the distance that it extends downwardly below the drink opening 122) may be at least 14 to 25 mm (total distance). In a preferred embodiment, as illustrated in FIG. 3F the baffle 200 extends downwardly below the bottom of the central section 124 of the lid. In such a configuration, the wall 202 of the baffle 200 extends downwardly to a point where fluid can impact the baffle, so that the baffle 200 is effective in dissipating fluid energy and thus the motion of the fluid in the container. Further, this distance is effective in preventing fluid from unintentionally travelling upwardly through the passage 204—in particular, even fluid with substantial upward energy/momentum will have insufficient energy to overcome gravity and travel through the passage 204 to the drink opening 122.
In one embodiment, as described above, the lid 100 is preferably formed in a molding process, where the baffle 200 is formed as part of the lid 100. In one embodiment, the one or more openings 210 may be formed in the manufacturing process. For example, once the lid is formed in the molding process, the lid 100 may be inverted and the bottom 206 of the baffle 200 may be punched or pierced in order to form the openings 210. In other embodiments, the baffle 200 might be perforated with a laser or the like.
In a preferred embodiment, and as illustrated in FIG. 4 the lid 100 is integrally stackable with other lids, meaning that one lid 100 can be placed on another with mating portions thereof located adjacent to one another (e.g. not merely set upon one another so that a bottom-most portion of one lid engages the top-most portion of another lid). This configuration is advantageous because it reduced the space the lids 100 occupy during transport and storage.
In order to facilitate this stacking arrangement, walls of the raised area 120 and the bottom of the flange 160 have a negative draft (e.g. tapers outwardly, when moving in the direction of the top 102 to the bottom 104 of the lid 100). Most importantly, as illustrated in FIG. 4, the wall 202 of the baffle 200 has a positive draft (e.g. tapers inwardly, when moving in the direction of the top 102 towards the bottom 104 of the lid 100). This allows the downwardly extending baffle 200 of one lid 100 to fit through the drink opening 122 and into the passage 204 of the baffle 200 of a lid beneath it, thereby allowing the lids 200 to be stacked in an inter-engaging arrangement.

Advantages of the Invention

The baffle 200 described above and the container 20 having a lid 100 with such a baffle 200, has particular advantages. A first advantage is that the baffle 200 reduces the energy of fluid moving towards the drink opening 122. The baffle 200 also diverts fluid away from the drink opening 122. For example, referring to FIG. 5, fluid that is moving generally laterally in the cup 20 hits the wall 202 of the baffle 200, which impedes the flow of fluid to the drink opening 122. Fluid that is moving towards the bottom 206 of the baffle 200 must flow through the openings 216 in order to enter the passage 204 and flow to the drink opening 122. This requires that the fluid flow through the openings 210. Due to the size and location of the openings 210, the baffle 200 slows (reduces the energy) of fluid flowing into the passage 204, reducing the chance that fluid has sufficient energy to travel upwardly through the baffle 200 and out of the drink opening 122.
The baffle 200 is thus effective in preventing the unwanted dispensing of fluid from the container 20 through the drink opening 122, such as if the container 20 is jostled, bounces or the like (such as when being carried, moved in a car, etc.).
Advantageously, however, a user can freely/intentionally dispense liquid from the container 20. By tipping the container 20, the user can allow fluid to cover the baffle 200 and then flow through the openings 210 into the passage 204 and to the drink opening 122, such as for drinking by the user.

Additional Aspects of the Invention

It will be appreciated that while the baffle 200 which is described above has particular advantages, the one or more baffles may have a variety of shapes (including sizes) and may include baffles having different shapes.
The one or more baffles may be solid or may define one or more openings or apertures, such as perforations, passages, etc. The openings, apertures, passages or other features might have the same size/shape or have different sizes and/or shapes, including based upon the location of the baffle.
The one or more baffles may have smooth surfaces or might comprise rough or modified surfaces, such as surfaces having features designed to interact with fluid to absorb energy from fluid and/or slow the movement of fluid.
The one or more baffles might be movable or have one or more movable portions, such as comprising movable flaps.
As indicated herein, embodiments of the invention may apply to containers of various configurations, including cans, bottles, cups, jugs, carafes, jars, etc. Such containers may be constructed from various materials including paper, plastic, foams, metal, glass, etc.
As indicated, the spill-prevention technology, such as the one or more baffles, might be associated with the top of a container, where the top does not comprise a removable lid. The one or more baffles may be used with lids having different configurations, including shapes, than the lid 100 illustrated in FIG. 3. As one example, the lid might be generally planar on the top or bottom (rather than having a raised area), or might have a central depressed area. The lid might also include one or more air holes. Further, instead of being designed to press fit onto the top rim of a cup, the lid might be configured to screw onto the cup, press fit into the cup or otherwise connect to the cup.
In a preferred embodiment, the one or more baffles which are associated with the container, such as the lid thereof, are designed to divert fluid (such as away from a drink opening), dissipate fluid energy, create redirecting fluid currents, and/or create cancelling fluid waves or currents, such as to divert fluid from or reduced the energy of fluid flow towards, a drink opening of the lid. In this regard, the one or more baffles might comprise or be referred to as barriers, diverters, obstacles, etc.
In one embodiment, the one or more baffles are associated with a container lid and an associated drink opening. In other embodiments, the one or more baffles may be associated with the container lid but be spaced from the one or more drink openings. In other embodiments, the one or more baffles may be associated with other portions of the container, such as main body thereof (such as the cup portion, a lower can portion) or a bottom portion. The one or more baffles may extend upwardly from the container, such as the lid thereof—such as by defining a passage which leads upwardly to a raised drink opening.
In one embodiment, as illustrated in FIG. 6, the baffle might essentially be integrated into the lid, such as by having the wall portion 202 thereof comprise a portion of the raised area 120 of the lid. Once again, the baffle 200 thus defines a passage 204 that extends from a bottom 206 of the baffle 200 upwardly to the drink opening 122 at the top surface of the lid 100.
In one embodiment, the wall or walls of the baffle 200 may extend downwardly generally perpendicular to the lid and may be generally straight. However, one or more portions of the baffle 200 might extend away from the lid 100 at an angle. Further, one or more portions of the baffle 200, such as one or more portions of the wall 202, might be curved (including arched, parabolic, etc.), such as to increase the surface area of the baffle 200, such as illustrated in FIG. 7.
In one embodiment, the one or more baffles may comprise a diverter, arch, or a wedge shaped element. A diverter may comprise a body that extends downwardly, such as from the bottom of a lid, in order to divert fluid away from an opening. The diverter might comprise, for example, a downwardly extending wall, where the wall may have various shapes. When the drink opening is positioned on the near side of the lid, the diverter might be located on the opposite side of the drink opening. As described above, a baffle may comprise a wedge shaped section or element that comprises a walled element which extends downwardly from the lid or upwardly from the lid at the drink opening, where the wedge shaped section may taper.
In some embodiments, combinations of two or more baffles might be utilized. For example, a baffle comprising a wedge shaped section such as described above might be associated with the drink opening. Another baffle comprising a diverter might be spaced from the wedge shaped section.
