Sippy Cup Replacement

Abstract

a regular, spoutless cup that provides more of the convenience of bottles and sippy cups to parents looking to wean their children off or avoid spouts from bottles and sippy cups. The cup has a lid, a body and optional legs. The lid has squeeze tabs that allow removal from the body portion. The lid and the body cooperate to provide flow control through at least one hole in the lid leading to the spout and at least one hole in a cover over the body. By rotating the lid and either alighing or not aligning the holes, the user can achieve flow control. The optional legs are attached to a ring that fits on the body. The legs can be laterally concave to provide superior properties that prevent tipping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] In a first embodiment, a cup 20 is supplied with a removable lid 1 and a set of legs 21. The cup body 20 is removable from the legs 21. The lid 1 is a soft material such as silicone rubber. The lid 1 has a number of holes 2 that allow adjustment for flow control. The lid 1 has a plate 3 that flexes to allow insertion and removal of the lid 1 from the cup body 20. There is a protrusion 4 attached to the plate 3 that allows locking under a mating cup lip 5 on the cup body 20. The cup lip 5 is undercut so that it locks over the protrusion 4 in the lid 1.

[0025] The cup body 20 has protrusions 6 that interface with the holes 2 in the lid 1. These protrusions 6 allow the lid to control flow rate. Cavities 7 on the cup portion 20 allows tabs 10 on the legs 21 to lock to hold them in place. There may also be an optional concave cut-out 8 on the cup portion 20 that allows easy gripping. The legs 21 can have a band 9 that receives the cup body 20. A tab 10 on each leg 21 mates with the cavities 7 in the cup body. This is shown in detail in FIG. 2.

[0026] Turning to FIG. 3, a detail is shown of the mating cup lip 5 on the cup body 20 and how it mates with the plate 3. The plate 3 has finger tabs 12 that allow deforming the plate 3 slightly. FIG. 3 shows the nature of the flexing of the plate 3 when a user presses on the finger tabs 12 bowing the plate 3 to allow the tabs on the plate to move inward towards the center of the cup and free of the cup lip 5.

[0027] FIG. 4 shows the lid holes 2 in three positions relative to the protrusions 6 on the cup body. In position A, the hole 2 is offset from the protrusion and allows full, unimpeded flow through the lid hole. In position B, the hole 2 is partially obstructed by the protrusion 6 and in position C, the hole 2 is fully obstructed, and the cup is sealed allowing no liquid to flow.

[0028] As viewed in FIG. 4, it can be see that it is advantageous that the protrusion 6 should not be centered between the legs 21, since it is preferable that the user drinks from the cup with the spout section as close to the center between the legs. When the spout is directly over the protrusion however, it will be in the fully blocked or closed position for carrying or transport. When the spout is in the closed position, the spout can be closer to one of the legs. Therefore the protrusion 6 should be offset to be closer to one of the legs, and not centered directly between them.

[0029] As illustrated, the present invention includes three separate parts: a lid 1, a cup body 20 and a leg assembly 21.

[0030] The lid is has a lip 1 with inward curved sections and a lowered section that may be curved outward for drinking. The body of the lid 1 may be made from a soft material such as a silicon material, overmolded over a flexing plate. The flexing plate 3 provides greater rigidity over the silicon body, but allows for flexing to allow the insertion and removal of the lid. The flexing is facilitated by the user pressing the finger tabs 12, which are proximate to the protrusions 4 in the lid 1 that serve as interlocking tabs in conjunction with the internal cup lip 5 (which protrudes into the interior of the cup for the purpose of interfacing with the interlocking tabs). As the user presses inward, this causes the flex plate to bow allowing the tabs to move towards the center of the cup and out of the way of the rim, thus allowing the lid to be removed from the cup.

[0031] The cup body protrusions 6 are designed to interface with the holes in lid 2 to provide flow control in the following manner: By positioning the holes 2 relative to the body protrusions 6, the user can select the amount of flow allowed. If the holes are positioned directly on top of the protrusions the flow is altogether stopped, and such a position seals the lid and cup, allowing the cup to be transported or stored without spilling. If the holes are positioned partially on top of the protrusions, and partially offset, then the holes are partially blocked, and the flow control is reduced, but not stopped altogether providing an effectively smaller hole for liquid to flow through. By varying the offset of the holes and protrusions the caregiver can modify the effective size of the hole to provide the desired orifice size to provide the optimal amount of liquid flow. Finally, the holes can be offset entirely from the protrusions, where the protrusions do not cover the hole at all, thus allowing the maximum liquid flow.

[0032] In FIG. 1, three finger tabs 12 are shown. These finger tabs are typically located between the lowered section of the lid 1 so that the user presses in areas that are away from the lower drinking areas of the cup, and hence, they do not have to press locations that the infant drinks from. It should be appreciated that instead of three locations, two (or another number of) finger tabs could be used.

[0033] FIGS. 5-6 show an alternate embodiment of the present invention. There is a lid 1, a cup body 20 and a set of lets 21. In this embodiment, a flow control cap 13 with a post 14 is employed to provide flow control in conjunction with the lid 1. The lid 1, in this embodiment, is a plastic cap with internal threads that screws on top of the external threads of a blow molded (or injection molded) cup body 20. Over molded on top of that cap is a soft lip and spout structure that has holes 2 in lid for flow control. In addition, the lid 1 has a keyed opening 15 that allows a flow control cap 13 to be inserted (and locked in place by rotating the cap and thereby moving the posts 14 away from the keys and under the lid 1). As shown in FIG. 7, the flow control cap 13 can further be rotated into three positions to control the aperture of the holes in lid to allow them to be fully open, fully closed or sealed (for transport or storage) or to be partially closed, further restriction the flow of liquid. In this embodiment, the band connecting the legs is captured between the threaded lid 1 and cup body 20 when they are screwed together. The user can thread the lid and cup body without including the legs if so desired.

[0034] Several descriptions and illustrations have been presented to aid in understanding the present invention. One with skill in the art will realize that numerous changes and variations may be made without departing from the spirit of the invention. Each of these changes and variations is within the scope of the present invention.
