Drinking vessel
A drinking vessel comprising a 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. Also, a drinking vessel comprising a 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.
The present application claims priority to provisional patent application 60/619,643, filed on Oct. 18, 2005 and to provisional patent application 60/694,218, filed on Jun. 27, 2005, both of which are incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention relates to a drinking vessel, and particularly to a cup with a lid to reduce the risk of spillage.
BACKGROUND OF THE INVENTIONDrinking 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.
SUMMARY OF THE INVENTIONOne 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.
BRIEF DESCRIPTION OF THE DRAWINGSFor the purpose of illustrating the invention, there are shown in the drawings forms of the invention which are presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.
Referring to the accompanying drawings, where like numerals identify like elements, and initially to
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 the spout 22 uppermost, as shown in
In one embodiment, the body 22 is asymmetrical in plan view. As best seen in
The cap 24 has an internally screw-threaded skirt 40 that threads onto the mouth 38 of the cup body 22. The spout 26 has one or more holes or other openings 42 in its tip through which a user can drink liquid from the cup 20. Below the spout, there is a tubular seat 44. The interior of the tubular seat 44 is substantially cylindrical.
A valve unit indicated generally by the reference numeral 50 consists of a valve holder 52, shown in
The upper end of the tube 64 has an internal seat 66 for the valve member 56, and above the internal seat an internal groove 68 into which the retaining ring 54 is a snap fit. The retaining ring 54 has an undersurface 70 that cooperates with the seat 66 to hold the valve member 56, an external rib 72 that is a snap fit into the groove 68 and, above the rib 72, a shoulder 74 that seats onto the upper rim of the tube 64. As may be seen from
The valve member 56 consists of a soft, flexible material such as silicone rubber, with one or more slits or holes 58 that open or close as the valve member 56 is distorted by external forces. The valve member 56 may be of any suitable design that will permit liquid to drain from the spout 26 back into the cup 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, the valve member 56 has an opening force of at least 6″ (15 cm) water gauge, but preferably not much more, for flow towards the spout 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
The shoulder 36 and the neck below it also make the cup 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
The base 82 of the receptacle 28, which serves as a base for the cup 20 to stand on, has an external screw threaded mouth 94, which screws into the downward skirt 84 of the lid 80, and has a bottom 96 that is slightly concave, to reduce the risk of the cup 20 wobbling when resting on the bottom 96.
If the receptacle 28 is removed, the cup 20 may rest on the bottom 30 of the cup body 22, which is also slightly concave. Referring to
As is also shown in
Referring now to
The base 130 of the receptacle 128 has an externally screw threaded mouth 94, which screws into the downward skirt 84 of the lid 80, and has a bottom 132 that is similar in shape to the bottom 30 of the cup body 22, bounded by a groove 134 similar to the groove 32. Thus, the lid 80 of the receptacle 128 may clip either onto the bottom 30 of the body 22 of the cup 20, or onto the bottom 132 of another similar receptacle 128. The cup 20 may have a neck 36 and mouth 38 (not shown in
As shown in
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.
