Abstract
A cup that is used for children that transitions them from sippy cups to conventional drinking cups. The cup does not require any suction by the child when drinking yet is spill proof when locked for transit. The cup features a reservoir, a top and a lid. Within the top is a central passage and a plate that contains vents. When closed, the lid is flush against the plate and prevents any liquid from leaking. When the lid is rotated open, a gap is exposed between the lid and plate to allow liquid to flow from the reservoir and through the vents to the child's mouth. Regardless of whether the lid is opened or closed, the lid always remains below the top rim of the top.
Description
FIELD OF THE INVENTION
The present invention involves the field of beverage containers. Specifically, the invention is directed to a beverage container for a child, or toddler, the beverage container being suited to transition the child from a sippy cup to a conventional drinking cup.
BACKGROUND OF THE INVENTION
Drinking vessels for infants and children are known. For example, it is desirable to provide cups to meet the special demands created by infants and toddlers. Currently available to meet these needs are spill proof cups, or sippy cups. Sippy cups features valves attached to a lid. Extending outwardly from the lid is a spout. As the child provides suction on the spout, the valve in the lid opens allowing fluid to pass from the reservoir of the cup through the spout and into the child's mouth. Sippy cups are ideal for transitioning an infant from a baby nurser to a cup-like vessel since both container only allow fluid to flow when suction is initiated by the child.
However, transitioning a child from a sippy cup to a conventional drinking cup can be an onerous task. The main difference between a conventional drinking cup and a sippy cup is that a conventional drinking cup requires minimal suction by the child. Furthermore, conventional cups have an open top thus making the cup susceptible to spilling large quantities of beverage whenever the cup is tipped. Furthermore, because there is no spout on a conventional cup, the child must maneuver the rim of the cup to her mouth and lift the cup to allow the fluid to flow into her mouth, thus, increasing the probability and occurrence of a spilling. Thus, it is desirable to provide cups with means to simulate the rim of a conventional cup while providing means achieve portability of the cup with minimal spillage.
SUMMARY OF THE INVENTION
It is thus an object of the present invention to provide cup that helps a child or toddler transition from a sippy cup to a conventional cup.
It is yet another object of the present invention to provide a cup that causes the child or toddler to drink from the rim of a cup rather than a nipple or spout.
It is a further object of the present invention to provide a cup that minimizes the occurrence of leaks and spills while the child is learning how to drink from a cup.
It is still a further object of the present invention to provide a cup that is lightweight, easily used and easily cleaned.
This and other objects and advantages of the present invention are achieved by a container adapted for use by a child, or toddler, that has, e.g., three separable components: a reservoir, a top and a lid. The reservoir serves to hold any potable liquid. The top threads onto the open end of the reservoir. The top optionally includes a plate that extends across the open end of the reservoir. The plate also includes a central passage therein and a groove along its upper perimeter. A rim projects and extends upwardly from the plate of the top. The lid includes an upper disc portion and a lower cylindrical portion projecting and extending from the bottom surface of the lid. The bottom of the upper disc portion has a perimeter edge that extends axially for engaging the groove of the plate. The lower cylindrical portion further includes flexible position tabs that snap onto an internal threaded wall that defines the central opening in the top. Upon attachment, the lid is positioned below the top edge of the upper rim of the top. The perimeter of the lid that touches the top forms a seal that prevents liquid from flowing out. The lid, e.g., is rotatable with respect to the top. The ramp of the internal threads causes, when the lid is rotated, a separation between the disc portion of the lid and the plate of the top. Vents in the plate of the top permit passage of beverage when the disc portion of the lid is separated from the surface of the plate. Regardless of whether lid is in an open or closed position, the lid always remains below the top edge of the rim of the top.
Numerous, other objects, features and advantages of the present invention will readily become apparent from the following detailed description, from the claims and from the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and, in particular,
FIG. 1
, there is shown an exemplary embodiment of a container of the present invention generally represented by reference number
10
. The container
10
is preferably substantially cylindrical in shape, but may be of any shape that is adaptable for use as a container by children. For the purposes of describing an exemplary embodiment of the container
10
, the container
10
is illustrated to be cylindrical. Thus, the three main components of container
10
, reservoir
100
, top
200
and lid
300
are substantially cylindrical and/or circular. The number of main components of the container
10
may be varied to be more or less. For example, the reservoir
100
and the top
200
may be formed as a single unitary component. All of the components of the container
10
may be of the same or different materials. For example, a preferred material is a thermoplastic polymer which, e.g., can be a homo-polymer or co-polymer. Examples of thermaplastic polymers include, but are not limited to, polyethylene, polypropylene, polystyrene, high-density polyethylene, low-density polyethylene, linear low-density polyethylene and mixtures thereof.
FIG. 2
depicts a front elevational view of the reservoir
100
. The reservoir
100
may be of any shape that is suitable for holding a liquid. For example, the reservoir
100
may be substantially cylindrical or take the form of a chalice or goblet, as shown in FIG.
2
. One skilled in the art may pick a shape for the reservoir
100
that is suitable for grasping and handling by children. Furthermore, the reservoir
100
should be able to contain a volume of liquid that is suitable for drinking by children. For example, any volume from about five ounces (approx. 147 mL) to about twelve ounces (approx. 355 mL).
Referring to
FIGS. 1 and 2
, the reservoir
100
has base
110
and top end
120
. The base
110
should be designed such that it can support the container
10
when the container
10
is vertical. The top end
120
serves as the exit point for the liquid from the reservoir
100
. The outer surface of the top end
120
has fastening structure
124
thereon. The fastening structure
124
allows top
200
to attach or connect to the reservoir
100
. For example, the fastening structure
124
can be an annular groove, an annular ring or a snap-fit. Preferably, the fastening structure
124
is a spiral or thread. This threading allows the top
200
to be threadably attached to the reservoir
100
. Although not necessary, having the top
200
be detachable from the reservoir
100
allows a user to better access the interior of the reservoir
100
for cleaning and filling.
FIGS. 3-5
show perspective, top and bottom views of the top
200
, respectively. The top
200
has top rim
210
, bottom rim
220
, outer wall
230
and inner wall
240
. Extending across the top
200
and from the inner wall
240
is plate
250
. The plate
250
is situated between the top rim
210
and the bottom rim
220
and parallel to the planes that contain the top rim
210
and the bottom rim
220
. The center of the plate
250
is a circular opening or central passage
252
. Along the perimeter of the central passage
252
is passage wall
254
. The passage wall
254
, e.g., is concentric with the outer wall
230
and the inner wall
240
. Around the top perimeter of the plate
250
is, e.g., a circular seal groove
251
. When the lid
300
is locked in top
200
, the groove
251
is in physical contact with the edge of lid
300
; this is discussed in more detail below. Located adjacent to the multiple guide slots
256
and on the passage wall
254
are position locks
258
. The position locks
258
can be located, e.g., clockwise or counterclockwise from the multiple guide slots
256
depending on the rotation of the lid
300
in the top
200
. For example, if the lid
300
were to be rotated clockwise with respect to the top
200
as viewed from the top, then each position lock
258
is located to the left of a corresponding guide slot
256
when viewing the bottom of the top
200
. The position locks
258
serve to hold lid
300
in an open, or “drink” position. The edge of each arcuate piece of the passage wall
254
between each guide slot
256
and the next locking slot
258
, e.g., between the guide slot
256
a
and the position lock
258
b
, is sloped or tapered as the position tabs
326
travel along such arcuate piece of the passage wall
254
. Also along the inner surface of the passage wall
254
are grooves, or drive ribs
257
. The drive ribs
257
serve as attachment points for the lid
300
, as will be seen later.
Disposed along the plate
250
between the passage wall
254
and the inner wall
240
are vents
260
. The vents
260
extend through the entire thickness of the plate
250
. The vents
260
can be of any shape, number and size. For example, as shown in
FIGS. 3 and 4
, vents
260
are trapezoidal in shape and are twelve in number. When the container
10
is tilted downward, liquid flows from the reservoir
100
and through the top
200
via the vents
260
.
FIGS. 6-9
depict top perspective, front, side and bottom perspective views of the lid
300
, respectively. The lid
300
provides a mechanism to seal the reservoir
100
and the top
200
to prevent any liquid from exiting the container
10
when the lid
300
is sealed. The lid
300
has upper portion
310
and lower portion
320
which are, for exampled, one-piece integrally formed together. The upper portion
310
is, e.g., a disc that has a diameter that approximates that of the inner wall
240
of the top
200
. Along the perimeter of bottom surface of upper portion
210
is edge
316
. For example, the edge
316
projects axially away from the bottom surface of upper portion. The edge
316
should have a thickness that is compatible with the width of groove
251
in the plate
250
. When the lid
300
is inserted in the top
200
and closed, the upper portion
310
of the lid is disposed or oriented below the top rim
210
of top
200
to form a physical seal. Additionally, e.g., when the lid
300
is closed, the upper portion
310
covers the vents
260
and prevents any liquid from flowing out of the reservoir
200
and through the vents
260
. When the lid
300
is opened or in an open position, the lid
300
remains disposed or oriented below the top rim
210
of top
200
. Although it is preferable that the edges of the upper portion
310
touch the inner wall
240
, e.g., to form a physical seal, when the lid
300
is locked or closed, it is not necessary provided that the vents
260
are sufficiently covered by the upper portion
310
when the lid
300
is locked or closed. On the top surface
312
of upper portion
310
is handle
314
. Handle
314
provides a means for a user to easily remove lid
300
from top
200
. Additionally, handle
314
provides a place for a user to grasp when rotating lid
300
.
Projecting from the bottom surface of the lid
300
is the lower portion
320
. Although as depicted in
FIGS. 5-7
, the lower portion
320
is cylindrical and has edge
322
, the lower portion
320
can be any other shape provided that such shape is compatible with the central passage
252
. What is meant by “compatible” is that the central passage
252
and the lower portion
320
have shapes that are similar. For example, if the central passage
252
is circular than the lower portion
320
is cylindrical and the edge
322
is circular. The diameters of the central passage
252
should closely match that of the lower portion
320
.
Along the distal end of the lower portion
320
opposite of the upper portion
310
are position tabs
326
. For example, the bottom portion
320
can have any number of position tabs
326
, preferably three. Each position tab
326
is located along the perimeter of -edge
322
and formed into wall
324
of the lower portion
320
. At the distal end of each position tab
326
is extension
328
, which projects and extends perpendicular and away from the axis of the lower portion
320
. Each extension
328
should match the shape of the guide slot
256
in the top
200
. For example, if the extension
328
has a semi-circular shape, then the guide slot
256
should also have a semi-circular shape. Located along the wall
324
in between the position tab
326
and the upper portion
310
are thread tabs
329
. For example, there is one thread tab
329
for each position tab
326
. The thread tabs
329
are protrusions in the wall
324
that extend radially from the wall
324
of the lower portion
320
. The thread tabs
329
prevent the lid
300
from falling out of the top
200
in the event that the container
10
is ever turned upside-down.
To assemble the container
10
, the top
200
is attached, e.g., by screwing, onto the reservoir
100
. The lid
300
is then inserted into the top
200
with the user ensuring that the position tabs
326
are aligned with the guide slots
256
. As the lid
300
is inserted into the top
200
, the position tabs
326
pass through the guide slots
256
. Once the lid
300
is fully inserted into the top
200
, the position tabs
326
engage the edge of the passage wall
254
. This engagement of the position tabs
326
with the edge of the passage wall
254
of the top
200
, e.g., helps to prevent the lid
300
from falling out of the top
200
when the container
10
is inverted or tipped over. As the user rotates the lid
300
in a clockwise fashion, the thread tabs
329
travel along the drive ribs
257
whereas the position tabs
326
travel along the arcuate section of the passage wall
254
. Finally, the lid
300
has a complete physical seal when the edge
316
of upper portion
310
of lid
300
is fully engaged with the groove
251
of the plate
250
of the top
200
.
To use the container
10
, the user rotates in a counterclockwise fashion the lid
300
a set number of degrees. The counter-rotation of the lid
300
creates a gap between the lid
300
and the inner wall
240
when the edge
316
of upper plate
310
of lid
300
is no longer fully engaged with groove
251
of the plate
250
of the top
200
. When the child drinks from the container
10
, fluid flows from the reservoir
100
through the vents
260
of the plate
250
and through the gap between the lid
300
and the inner wall
240
and ultimately into the user's mouth. No or minimal suction by the user is required or needed.
Additional features as known in the art can be added to the container
10
to enhance userability. For example, visual markers can be incorporated into the container
10
to show when the lid
300
is property aligned with top
200
to facilitate easy insertion of the lid
300
into the top
200
. An example of a visual marker is an arrow on the lid
300
and a corresponding arrow on the top
200
. Moreover, audible markers can be incorporated to signal to the user that the lid
300
has been locked: e.g., when the position tabs
326
are rotated into the is position locks
258
, a “click” sound can be heard. Furthermore, to enhance the spill-proofness of the container
10
, a gasket can be incorporated between the lid
300
and top
200
.
