Description
- The present application claims priority to
provisional patent application 60/619,643, filed on Oct. 18, 2005 and toprovisional patent application 60/694,218, filed on Jun. 27, 2005, both of which are incorporated herein by reference. - The present invention relates to a drinking vessel, and particularly to a cup with a lid to reduce the risk of spillage.
- Drinking cups for young children are sometimes provided with a lid having a spout through which the child can drink. The spout is sometimes provided with a valve that is intended to permit liquid to flow out of the cup only when the child sucks on the spout. This type construction is intended to reduce the risk of spillage or to reduce the volume of liquid spilt, if the cup falls or is knocked over. Similar cups are sometimes used by adults in circumstances where it is particularly important to minimize the risk of liquid spillage, for example, in libraries.
- Commonly-assigned U.S. Pat. No. 5,890,621 to Bachman et al., which is incorporated herein by reference in its entirety, describes a drinking cup in which the suction valve also acts as a return valve, permitting air to enter the cup, and permitting any liquid left in the spout after the child drinks to drain back into the cup. The silicone rubber valve is carried in a valve unit that is a press fit in the cap. The valve is held in the unit by a snap fit retainer. Thus, the unit can easily be removed from the cap so that the valve, the unit, and the cap can be easily cleaned.
- One embodiment of the invention provides a drinking vessel comprising: a container for retaining a quantity of liquid, the container having a mouth and an internal shoulder; a cap for closing the mouth of the container and having an outlet for liquid; and a valve unit removably mountable on the cap and arranged to control flow of liquid to the outlet; the valve unit being so arranged that the shoulder prevents the valve unit from being separated from the cap while the cap is mounted on the container.
- Another embodiment of the invention provides a drinking vessel comprising: a container for retaining a quantity of liquid, the container having an outlet for liquid; and a receptacle removably attachable to an end of the container remote from the outlet of the container; wherein the receptacle comprises parts relatively movable between a substantially closed position and a position providing an orifice for releasing objects from within the receptacle; wherein the receptacle is arranged to be attached to the container in such a position that the container closes off the orifice.
- A further embodiment of the invention provides a storage container attached or attachable to the bottom of a drinking vessel, which storage container is attachable to the bottom of an identical storage container.

FIG. 10 is a view similar toFIG. 1 , showing the cap and valve unit in exploded view. -
FIG. 11 is a cross-section similar to part ofFIGS. 2 and 3 showing a second embodiment of an attached storage container. - Referring to the accompanying drawings, where like numerals identify like elements, and initially to
FIGS. 1, 2 , and 10, there is shown one form of a drinking vessel according to the present invention, in the form of a cup identified generally byreference numeral 20. Thecup 20 has abody 22 and acap 24 with aspout 26. Areceptacle 28 for dry material is clipped onto the bottom of the cup. - Throughout this specification, terms such as “top”, “bottom,” and “vertical” are used in the interest of clarity with reference to an orientation of the
cup 20 in a typical resting position, standing on a level surface with thespout 22 uppermost, as shown inFIG. 1 . It is not required that the cup be maintained exactly in this orientation. In use, it will usually be necessary to tip the cup in order to drink from it. Also, when empty, the cup, or its separate parts if it is dismantled, may be stored and transported in any convenient orientation. - In one embodiment, the
body 22 is asymmetrical in plan view. As best seen inFIG. 2 , thebody 22 has arounded bottom 30 bounded by agroove 32 that serves for thereceptacle 28 to clip onto, and has a main side wall that narrows gradually towards the top, ending in a neck or inwardly-projectingshoulder 36 above which thebody 22 widens to an externally screw-threadedmouth 38. - The
cap 24 has an internally screw-threadedskirt 40 that threads onto themouth 38 of thecup body 22. Thespout 26 has one or more holes orother openings 42 in its tip through which a user can drink liquid from thecup 20. Below the spout, there is atubular seat 44. The interior of thetubular seat 44 is substantially cylindrical. - A valve unit indicated generally by the
reference numeral 50 consists of avalve holder 52, shown inFIGS. 5 and 6 , avalve retainer 54, shown inFIG. 7 , and avalve member 56, shown inFIGS. 8 and 9 . Thevalve holder 52 has abase plate 60, which in the position shown inFIG. 1 is generally horizontal, and a downwardly projectinggrip 62. Projecting upwards from thebase plate 60 is atube 64, the inside of which opens through thebase plate 60 and the outside of which is inserted, when the cup is assembled, into theseat 44. As best seen inFIG. 4 , the outside surface of thetube 64 is a gently tapering truncated conical surface, narrowest at the open top end, and widest at the bottom end, where it joins thebase plate 60. Thetube 64 and theseat 44 are dimensioned to produce a snug, stable fit between the outside of the tube and the inside of the seat. - The upper end of the
tube 64 has aninternal seat 66 for thevalve member 56, and above the internal seat aninternal groove 68 into which theretaining ring 54 is a snap fit. Theretaining ring 54 has anundersurface 70 that cooperates with theseat 66 to hold thevalve member 56, anexternal rib 72 that is a snap fit into thegroove 68 and, above therib 72, ashoulder 74 that seats onto the upper rim of thetube 64. As may be seen fromFIG. 4 , the outside diameter of theretaining ring 54 is less than that of thetube 64, so that theretaining ring 54 does not foul theseat 44. In one embodiment,retaining ring 54 is sonic welded totube 64. Sonic welding can be done so that theretaining ring 54 andvalve member 56 are not removable from thevalve unit 50 in normal use. - The
valve member 56 consists of a soft, flexible material such as silicone rubber, with one or more slits orholes 58 that open or close as thevalve member 56 is distorted by external forces. Thevalve member 56 may be of any suitable design that will permit liquid to drain from thespout 26 back into thecup body 22 when the cup is standing upright, will not leak to any appreciable extent if the cup is overturned, and will permit liquid to be sucked from the cup without great effort. Thus, thevalve member 56 has an opening force of at least 6″ (15 cm) water gauge, but preferably not much more, for flow towards thespout 26, but leaks slightly for even minimal head of liquid in the opposite direction. - A suitable design of
valve member 56 is shown in U.S. Pat. Nos. 5,409,144 (Brown) and 5,439,143 (Brown et al.), both assigned to Liquid Molding Systems, Inc., of Midland, Mich., which are herein incorporated by reference in their entirety. - As is best seen in
FIG. 4 , thevalve holder 52 is dimensioned so that, with thetube 64 inserted into theseat 44 and thecap 24 screwed onto thebody 22, theedge 76 of thebase plate 60 lies just above theinternal shoulder 36 on thecup body 22, at least at the part of theedge 76 that is nearest to thetube 64. In this position, theshoulder 36 prevents thevalve unit 50 from moving downwards far enough for thetube 64 to disengage from theseat 44. The risk that theunit 50 will separate from thecap 24, leaving thespout 26 unprotected against spillage, is thus greatly reduced. - The
shoulder 36 and the neck below it also make thecup 20 easier for a child to grip securely, because even if the child's grip is loose, the shoulder can rest on the child's hand or hands and prevent the cup from slipping out of the child's grasp. - Referring now to
FIG. 2 , thereceptacle 28 comprises alid 80 and abase 82. Thelid 80 has adownward skirt 84, with an internal screw thread, and anupward skirt 86. Theupward skirt 86 is shaped to fit closely round thecurved bottom 30 of thecup body 22, and has at its rim aninternal bead 88 that snaps into thegroove 32. Inwardly of theskirts lid 80 has anopening 89 that can be closed by ashutter 90 that rotates about apivot 92 that snaps into a hole at the center of the lid. - The
base 82 of thereceptacle 28, which serves as a base for thecup 20 to stand on, has an external screw threadedmouth 94, which screws into thedownward skirt 84 of thelid 80, and has a bottom 96 that is slightly concave, to reduce the risk of thecup 20 wobbling when resting on the bottom 96. - If the
receptacle 28 is removed, thecup 20 may rest on the bottom 30 of thecup body 22, which is also slightly concave. Referring toFIG. 3 , alternatively, aseparate standing base 100 may be clipped on in place of thereceptacle 28. The base 100 shown inFIG. 3 has anupper part 102 similar in shape to the upper part of theupward skirt 86 of thelid 80 shown inFIG. 2 , including abead 88 that snaps into thegroove 32 in thebody 22 of thecup 20. Alower part 104 of thebase 100 follows loosely the shape of the bottom 30 of thecup body 22. Thelower part 104 has downward bulges 106 that act as feet when thecup 20 is standing on thebase 100. There may be fourbulges 106 evenly spaced round thebase 100. The right half ofFIG. 3 shows a section through abulge 106. The left half ofFIG. 3 shows a section betweenbulges 106. The standingbase 100 may be of soft, rubbery material, with less tendency to slide on smooth surfaces than the bottom 30, which may be fairly hard and stiff for the structural integrity of thecup body 22. Drainage holes 108 may be provided in the bottoms of thebulges 106. - As is also shown in
FIG. 3 , the externally screw-threadedmouth 38 of thecup body 22 may be tilted relative to the bottom 30, 96, or 100 on which thecup 20 stands. In the arrangement shown inFIG. 3 , the screw threads on themouth 38 and theskirt 40 of thecap 24 are single-start threads, aligned so that with thelid 24 screwed tightly onto thebody 22 thespout 26 is at the highest point of themouth 38. This may improve the drinking function of thecup 20, because with thespout 26 at a convenient angle for drinking from thecup body 22 is then tipped higher. - Referring now to
FIG. 11 , an alternative form of thereceptacle 128 comprises alid 80 and abase 130. Thelid 80 of thereceptacle 128 may be identical to thelid 80 of thereceptacle 28 shown inFIG. 2 and, in the interests of conciseness, description of the lid is not repeated. - The
base 130 of thereceptacle 128 has an externally screw threadedmouth 94, which screws into thedownward skirt 84 of thelid 80, and has a bottom 132 that is similar in shape to the bottom 30 of thecup body 22, bounded by a groove 134 similar to thegroove 32. Thus, thelid 80 of thereceptacle 128 may clip either onto the bottom 30 of thebody 22 of thecup 20, or onto the bottom 132 of anothersimilar receptacle 128. Thecup 20 may have aneck 36 and mouth 38 (not shown inFIG. 11 ) as shown inFIG. 2 orFIG. 3 . Onto the bottom 132 of thereceptacle 128 may be clipped either the standingbase 100 shown inFIG. 3 or thelid 80 of anothersimilar receptacle 128. - As shown in
FIG. 11 , a stack may be formed by clipping together acup 20, one ormore containers 128, and a standingbase 100. Alternatively, a stack ofcontainers 128 without acup 20 and/or without a standingbase 100 may be formed, or asingle receptacle 128 may be stacked with acup 20 and/or with a standingbase 100. However, because the bottom 132 of thereceptacle 128 is more rounded than the bottom 30 of thereceptacle 28, it may be preferred to use a standingbase 100 to increase the stability of tall stacks. Alternatively, the bottom of a stack may be acontainer lid 80 that does not have a container body screwed into it, or acontainer body 82. - The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention. Other variations are contemplated and will be understood by those in the art.
