Abstract

A container for a spillproof assembly has a main body which is substantially round is viewed in top plan, with a first wing 24 protruding from a side. The container may have a second wing 26 on the other side, with matching first and second wings 16, 18 on the lid. Lid wing 16 may have a view window 38, through which, a snap ridge on the container first wing 24 may be seen, to check the lid has been tightened properly. An acoustic waveguide (figs 4, 10 & 11), with communicating sound generating structure 38, may create an audible click when the lid has been tightened onto the container. The acoustic waveguide acts as the viewing port 38 so that a user can visually verify the position of the lid body. The wings of lid body may slightly interfere with and cam over respective upper platforms on the wing portions of the container body so that a user will be provided with a tactical feedback as a lid body is approaching an optimal amount of tightness. The wings may enhance the grippability of, and properly orientate, the container assembly for small children.

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Non-Provisional Application Serial No. 13/192,438, filed July 27, 2011; and U.S. Non-Provisional Application Serial No. 13/192,440, filed July 27, 2011; U.S. Non-Provisional Application Serial No. 13/192,441, filed July 27, 2011; and U.S. Provisional Application Serial No. 61/493,132, filed June 3, 2011; the contents of all of which are hereby incorporated by reference herein in their entirety into this disclosure.

BACKGROUND

1. Technical Field

[0002] The subject disclosure relates generally to the field of feeding accessories, and more particularly to spillproof container assemblies, such as those that can be used as training cups for toddlers.

2. Description of the Related Technology

[0003] A wide variety of spillproof container assemblies, such as those that are used as training cups for toddlers, have been commercially available for decades. Such products typically include a container body such as a cup or baby bottle and a lid that is constructed and arranged to form a seal with respect to the container body. The lid is provided with an opening to permit controlled passage of fluid from the container body for drinking purposes.

[0004] In some products, the lid is provided with a valve mechanism that seals the opening unless drinking suction is applied to the opening by a user, or that seals the opening until the drinking cup assembly is inverted. In other products, the drinking opening in the lid is unrestricted, but a valve is provided within a second opening in the lid to impede the entry of makeup air into the container body, except when suction is being applied to the drinking opening.

[0005] Another type of spillproof container assembly includes a lid that is provided with an integral flexible straw that is movable between a crimped or folded position in which the lumen of the straw is substantially closed and an extended position in which the lumen is open throughout the length of the straw. In the latter position, free passage of fluid is permitted through the straw, enabling a user to drink through the straw. In other products, the lid is provided with an integral drinking spout that extends upwardly from the rest of the lid.

[0006] For purposes of this document, a spill resistant container assembly shall be considered spillproof. A spill resistant container assembly is typified by an unrestricted opening in the lid that is sized small enough to limit the amount of fluid that can be spilled if the container assembly is dropped or inverted.

[0007] in most spillproof drinking cup assemblies, the lid and the container body are provided with mating helical threads to enable the lid to be securely fastened onto the container body by screwing. If the lid is not fully screwed onto the container body, both leakage of fluid and undesirable entry of makeup air into the container body can occur. On the other hand, if the lid is overtightened with respect to the container body, undesirable deformation of the threads and sealing surfaces of the product can occur, and the lid can be a difficult to remove by the consumer. A lid that is difficult to remove because it is too tightly fastened onto the container body can itself lead to spilling of the contents of the container body as the user struggles to remove the lid.

[0008] Small children in the age range that typically use training cups do not have the hand eye coordination of older children or adults. The lid portion of most spillproof drinking cup assemblies that includes the drinking straw or spout is typically asymmetrical, requiring a small child to hold the drinking cup assembly during drinking in an orientation that properly positions the straw or drinking spout with respect to his or her mouth. It is difficult for many small children to securely grip many commercially available training cups while they are drinking, and to achieve and maintain the optimum orientation for drinking.

100091 In addition, both the lids and the cup bodies of most commercially available spillproof cup assemblies are typically substantially cylindrical in transverse cross-section. They can be difficult for a caregiver to grip during tightening and untightening of the lid onto the container body, particularly if the article is wet with rinse water or condensate.

[00010] There is therefore a need for a spillproof container assembly that provides guidance to consumers as to the proper degree of tightening between the lid and the container body. There is also a need for a spillproof container assembly that is constructed and arranged to optimize grippability for both small children and caregivers as well as promote optimum orientation of the container assembly by a small child during use.

DETAILED DESCRIPTION

[00042] Referring now to the drawings, wherein like reference numerals designate corresponding structure throughout the views, and referring in particular to FIGURES 1-2, a spillproof container assembly 10 that is constructed according to an embodiment of the subject disclosure includes a lid body 12 that has a generally circular lid main body 14 as viewed in top plan, best seen in FIGURE 4.

[00043] In FIGURE 4, the Lid body 12 includes at least one lid wing that protrudes radially outwardly from a first side of the main body 14. The lid body 12 includes a first lid wing 16 that protrudes radially outwardly from a first side of the lid main body 14, and a second lid wing 18 that protrudes radially outwardly from a portion of the lid main body 14, which is disposed on a second side that is opposite the first side. The lid wings 16, 18 may be provided substantially diametrically opposed. Alternatively, the lid wings 16, 18 could be positioned so that they are located as if at 2:30 and 9:30 on a clock and/or any other suitable orientation and/or configuration according to this subject disclosure.

[00044] A lid wing 16, 18 forms part of the sidewal I of the lid body 12. A solid handle 92 (such as shown in FIGURE 12) that extends outwardly from a lid is to be differentiated from a lid wing 16, 18 for purposes of this document. As discussed in more detail later, the lid wings 16, 18 include the structure 56 according to this subject disclosure.

1000451 Alternatively, the lid body could be fabricated to have just a single lid wing (not shown), or multiple lid wings that may be spaced circumferentially about the outer periphery of the lid body. For example, the lid body could have three lid wings (not shown) that are spaced 1200 apart. The lid body may include only a single lid wing (not shown) positioned anywhere about the lid body.

1000461 Referring back to FIGURES 1-4, the lid body 12 is preferably constructed and arranged to receive a flexible insert 28, which has a makeup air valve 29 integrally formed therein. The flexible insert 28 is preferably fabricated from a flexible material such as silicone and preferably defines an upstanding drinking spout 1, which has an opening 20 defined therein that is in communication with an interior space of the cup assembly 10 that may hold liquid such as a beverage. In the preferred embodiment, the lid body opening 2 in the lid body 12 for receiving the flexible insert 28 is symmetrical so that the flexible insert 28 can be inserted facing in either direction.

1000471 The spillproof container assembly 10 further includes a container body 22 having a generally circular main body 23, as may be seen in cross section in FIGURE 5. The container body 22 is also shown in perspective without the lid body 12 in FIGURE 11. Alternatively, the container body could be a baby bottle, bowl, snack catcher or trap, a fresh food feeder item, freezer trays, caps, feeder pouch and/or any other type of container that is constructed and arranged to receive a lid. Likewise, the audible click-lock securement structure described herein for facilitating releasable attachment of the container body to a lid may be integrated into any adjustable mechanical mechanism adapted to provide audible feedback of an engagement between two complementary components. The container body 22 may be constructed to have a volumetric capacity that is less than about 30 ounces, more preferably less than about 20 ounces and most preferably less than about 12 ounces. The container body 22 could be embodied within the ambit of the subject disclosure as any one of various types of containers as mentioned above.

1000481 As shown in FIGURES 1 and 11, the container body 22 includes at least one container wing that protrudes radially outwardly from a first side of the cup main body 23, which enables a consumer to grip and exert torque on the container body 22 during tightening and untightening of the lid body 12. In the preferred embodiment, the container body 22 includes a first cup wing 24 that protrudes radially outwardly from a first side of the cup main body 23 and a second cup wing 26 that protrudes radially outwardly from a second, opposite side of the cup main body 23. The respective cup wings 24, 26 both preferably form part of the upper surface of the container body 22. The cup wings 24, 26 are preferably substantially diametrically opposed, but could be positioned so that they are not diametrically opposed, such as if they were located at 2:30 and 9:30 on a clock and/or any suitable position in accordance with this subject disclosure.

1000491 For purposes of this document, a cup wing may be considered to be integral with and form part of the interior of the sidewall of the container that contains beverage or other fluid or material substance provided therein. For example, an external accessory such as a solid handle (as shown in FIGURE 12) may be differentiated from a container or cup wing for purposes of this document.

[00050] Alternatively, the container body could be provided with a single container wing, or multiple container wings. By grasping the larger oblong wings 16, 18 on the lid and the wings 24, 26 of the container body, a user is able to more conveniently clasp and exert relative opposing torque between the lid and the container body in order to tighten and untighten the lid onto the container.

1000511 As shown in FIGURES 1 and 11, each of the cup wings 24, 26 is preferably tapered so as to decrease in width as viewed in top plan as it extends away from the generally circular main body 23 in order to conveniently grip the cup wings 24, 26. In addition, each cup wing 24, 26 preferably have a distal surface 27 that is substantially flat. Moreover, as is best shown in FIGURE 3, each of the cup wings 24, 26 preferably is tapered as viewed in side elevation so as to decrease in width from top to bottom.

1000521 Both the lid body 12 and the container body 22 are preferably fabricated from a plastic material such as polypropylene, polyethylene or high-density polyethylene using a process such as injection molding and/or any other suitable material according to this subject disclosure.

[00053] As may best be seen in FIGURE 5, the lid body 12 is constructed and arranged to be screwed onto the container body 22. In operation, at least one helical lid thread 62 is provided on an inner circumferential surface 3 of the lid body 12, which mates with at least one helical cup thread 64 that is defined on an outer circumferential surface 4 of the circular main body 23 of the container body 22.

[00054] Preferably, the first lid wing 16 is substantially aligned with the first cup wing 24 and the second lid wing 18 is substantially aligned with the second cup wing 26 when the lid body 12 is screwed onto the container body 22 to a predetermined optimum tightness and relative position. As will be described in greater detail below, the spillproof drinking container assembly 10 provides visual, audible and tactical feedback to a user in determining when the optimum design tightness and position has been reached between the lid body 12 and the container body 22 to establish a seal.

[00055] As shown in FIGURE 4, the first lid wing 16 has a first viewing port 38 defined therein, and the second lid wing 18 has a second viewing port 40 defined therein. Preferably, a portion of the first cup wing 24 is visible through the first viewing port 38 and a portion of the second cup wing 26 is viewable through the second viewing port 40 when the lid body 12 has been tightened onto the container body 22 to the predetermined optimum closed position and tightness.

[00056] Referring to FIGURES 7 and 8, a visual indicator 72 is provided on a platform 68 located on an upper portion of the respective cup wing 24, 26 that is viewable through the respective viewing port 38, 40. The visual indicator 72 maybe a different color from at least a portion of the surface defining the respective viewing port 38, 40.

1000571 As may best be seen in FIGURE 11, the platform 68 is preferably substantially flat, and is further substantially disposed within a plane that is substantially normal to a longitudinal axis A of the container body 22. The platform 68 forms part of an upper surface of the container body 22. Platform 68 has an area that may be substantially within a range of about 25 mm to about 1000 mm, more preferably substantially within a range of about 35 mm to about 600 mm and most preferably substantially within a range of about 45 mm to about 350 mm.

100058] As shown in FIGURES 1-4, the first and second lid wings 16, 18 preferably substantially correspond in size and shape, particularly in their extent of radial projection, to the first and second cup wings 24, 26. Preferably, the first and second lid wings 16, 18 are substantially symmetrical to each other and substantially identical in size and in shape. Similarly, the first and second cup wings 24, 26 may be substantially symmetrical to each other and substantially identical in size and shape.

1000591 Referring to FIGURE 4, it will be seen that the first lid wing 16 extends radially outwardly from the lid main body 14 by a first distance DI, and the second lid wing 18 extends radially outwardly from the lid main body 14 by a second distance D2, which is preferably substantially identical to the first distance Di. As FIGURE 5 shows, the lid body 12 has a maximum lateral dimension DmAxi shown in FIG. 4, while the container body 22 has a maximum lateral dimension DMAx2.

[00060] In the preferred embodiment, a ratio Di/DmAxi of the radial projection of the lid wing 16 to the maximum lateral extent of the lid body 12 may be within a range of about 0.03 to about 0.25, may preferably be substantially within a range of about 0.04 to about 0.20 and may preferably be substantially within a range of about 0.05 to about 0.16.

[00061] As shown in FIGURE 8, each of the lid wings 16, 18 further has a maximum width WMAX as measured on its outermost surface. Preferably, a ratio of the maximum width WMAX to the maximum lateral extent DMAX of the lid body 14 is substantially with a range of about 0.3 to about 0.85, more preferably substantially within a range of about 0.35 to about 0.8 and most preferably substantially within a range of about 0.4 to about 0.7.

[00062] As is also shown in FIGURE 5, the first cup wing 24 extends radially outwardly from the cup main body 23 by a third distance D3, while the second cup wing 26 extends radially outwardly from the cup main body 23 by a fourth distance D4, which is preferably substantially identical to the third distance D3. The distances D3, D4 may be at least substantially about 0.1 inch or the like. In another exemplary embodiment, the distances D3, D4 may be at least substantially about 0.2 inch.

[00063] In the preferred embodiment, a ratio DI/DmAx2 of the radial projection of the first cup wing 24 to the maximum lateral dimension DALAX2 of the container body 22 is substantially within a range of about 0.03 to about 0.25, more preferably substantially within a range of about 0.04 to about 0.20 and most preferably substantially within a range of about 0.05 to about 0.16.

1000641 As shown in FIGURES 4 and 5, the first distance Di is substantially the same as the third distance DI, while the second distance D2 is preferably substantially the same as the fourth distance D4. In other words, the cup wings 24, 26 preferably protrude radially to about the same extent as the radial protrusion of the respective lid wings 16, 18. In a closed position, an outermost edge of the first and second lid wings 16, 18 and the outermost edge of the first and second container wings 24, 26 are substantially flush with each other.

1000651 As FIGURE 1 shows, indicia 30 may be provided on the lid body 12, preferably on an outer surface of one or more of the lid wings 16, 18, to indicate to a user that tactile, visual and audible feedback is available to verify when the position of the lid body 12 has been fully screwed onto the container body 22. In this exemplary embodiment, indicia 30 is embodied as a lock icon.

[00066] As shown, the container body 22 may be constructed generally in an hourglass shaped, having a narrowed waist 32 that is provided with a plurality of gripping ribs 34 and an expanded lower portion 36. The container body 20 has a textured side panel 46, best visible on FIGURE 3, with a plurality of gripping ribs 38. The textured side panel 46 preferably has an hourglass shape, with an upper end 48 that merges into a lower portion of the respective cup wing 24, 26, a larger lower end 50 and a narrowed central portion 52.

[00067] As shown in FIGURES 4 and 7-10, the securement structure 56 for providing audible feedback when the lid body 12 reaches a predetermined position in which it has been optimally positioned and tightened with respect to the container body 22 is best. The securement structure 56 may be referred to as a locking or positioning structure adapted to provide the audible feedback. In the preferred embodiment, the structure 56 for providing audible feedback includes a first portion that is defined on at least one of the lid wings 16, 18 and a second portion that is defined on at least one of the cup wings 24, 26.

[00068] The structure 56 for providing audible feedback includes an acoustic waveguide 78 on both of the lid wings 16, 18 that is defined as part of the respective viewing port 38, 40, and a flexible tab 58 that is cantilevered inwardly into the viewing port 38, 40 from an outboard side 60 of the sidewall defining the respective viewing port 38, 40. By connecting the flexible tab 58 to the outboard side 60 as opposed to the inboard side, interruption of the cup threads 64 may be avoided.

[00069] As FIGURE 9 shows, the flexible tab 58 preferably has a horizontal leg 74 that has a first length LT, and a vertical leg 76 that extends downwardly from the horizontal leg 74 and has a height Hs. Accordingly, the flexible tab 58 is preferably L-shaped. Height Hs may be substantially within a range from about 2 mm to about 10 mm. Height Hs may also be constructed substantially within a range of about 3 mm to about 9 mm, as well as within a range of about 4 mm to about 7 mm.

[00070] The flexible tab 58 may be fabricated from a relatively hard plastic material such as polypropylene, ABS, polyvinyl chloride, nylon or polyethylene terephthalate. Preferably, the flexible tab 58 has a modulus of elasticity that is substantially within a range of about 0.0001 to about 25 GPa, more preferably substantially within a range about 0.0008 to about 18 GPa, and most preferably substantially within a range of about 0.00159 to about 12.1 GPa.

[00071] Additionally, flexible tab 58 may have a hardness that is substantially within a range of about 10 to about 150 Rockwell R, more preferably substantially within a range of about 15 to about 130 Rockwell R and most preferably substantially within a range of about 20 to about 117 Rockwell R. 1000721 The flexible tab 58 may be mounted so that it is in acoustic communication with the respective port 38, 40, and is more preferably positioned within the respective port 38, 40, which is also the acoustic waveguide 78.

[00073] The structure 56 for providing audible feedback further preferably includes a snap projection for engaging and temporarily restraining the flexible tab 58 while the lid body moves with respect to the container body 22 toward the predetermined optimum closed position. In the preferred embodiment, the snap projection is embodied as a snap ridge 66 that projects upwardly from the raised platform 68 that is located at the uppermost portion of the respective cup wing 24, 26. Alternatively, the snap projection could be a single or multiple bumps or posts, which could work individually or as a group to engage the flexible tab 58.

[00074] The snap ridge 66 preferably has a height HR that may be substantially within a range of about 0.1 mm to about 1.3 mm, more preferably substantially within a range of about 0.3 mm to about 1.2 mm and most preferably substantially within a range of about 0 5 mm to about 0.9 mm.

[00075] As the lid body 12 approaches the optimal predetermined position and tightness with respect to the container body 22 as it is being screwed onto the container body 22, the lowermost surface of the vertical leg 76 of the flexible tab 58 will travel across the upper surface of the platform 68 and engage the snap ridge 66. This causes the flexible tab 58 to flexibly deflect like a leaf spring as the lid body 12 continues to move with respect to the container body 22, until the lowermost surface of the vertical leg 76 cams itself over the upper surface of the snap ridge 66. Preferably, the snap ridge 66 has a substantially symmetrical profile when viewed in transverse cross-section. When the upper surface of the snap ridge 66 can no longer restrain the flexible tab 58, the energy that is stored as a result of the elastic deflection of the flexible tab 58 will suddenly be released by an audible clicking sound, and the flexible tab 58 will resonate within the acoustic waveguide 78. This is felt and heard by a consumer as a distinctive vibration and clicking sound.

1000761 Referring to FIGURES 7 and 10, the clicking sound is then funneled upwardly and amplified by the acoustic waveguide 78, which is megaphone shaped, having an upper portion 42 that is wider than the lower portion 44. The clicking sound is concentrated in a given direction, and the coupling of its energy to the air is optimized by the acoustic waveguide 78. The audible feedback that is provided to the consumer when the lid body 12 has reached the optimal predetermined position with respect to the container body 22 is thus maximized.

100077] Preferably, the flexible tab 58 is constructed and arranged to be laterally deflected during its engagement with the snap ridge by a distance DT,n, (as shown in FIGURE 10) that may be substantially within a range of about 1 mm to about 5.5 mm, more preferably substantially within a range of about 2 mm to about 4.75 mm and most preferably substantially within a range of about 3 mm to about 4 mm 1000781 The structure 56 for providing audible feedback in the first lid wing 16 is synchronized to the structure 56 in the second lid wing 18 so that the clicking sound by the respective flexible tabs 58 are simultaneous. Accordingly, the snap ridge 66 on the first cup wing 24 is preferably substantially diametrically opposed to the snap ridge 66 on the second cup wing 26, and the flexible tab 58 on the first lid wing 16 is substantially diametrically opposed to the flexible tab 58 on the second lid wing 18. Alternatively, the respective structures 56 could be slightly staggered or offset from a precise diametric opposition so that the clicking sounds are sequential. The snapping effect of the flexible tabs 58 snapping away from the snap ridge 66 causes a tactile feeling andlor vibration to the user tightening the container body onto the lid. Likewise, in addition to the audible and tactile feedback, visual confirmation can also be visually received by a user viewing through the viewing ports 38, 40 the alignment of the structure 56 in the closed position.

[00079] Additional embodiments of the subject disclosure are shown in FIGURES 12-20. In each of these embodiments, the function and purpose of the lid wings, cup wings and the visual, tactile and acoustic feedback systems is substantially the same as described above with respect to the preferred embodiment, and differ from the preferred embodiment only in terms of aesthetic form, the presence of additional handles and different types of drinking mechanisms.
