BACKGROUND OF THE INVENTION

[0004] Pre-filled beverage containers come in all shapes and sizes. More particularly, disposable beverage containers come in various forms, from glass bottles to aluminum cans to paper and plastic cups. These disposable beverage containers provide a great deal of convenience in that they never require cleaning and are readily available for consumption. However, a large segment of the population is currently unable to take advantage of the convenience of pre-filled disposable beverage containers. For children making the transition from bottle to cup, a suitable pre-filled disposable beverage container is not currently available.

[0005] Every child between the infant and preschool stages makes the transition from bottle to cup. Commonly, children during this stage use “sippy cups” in order to gain a feel for drinking from a regular cup. These “sippy cups” generally use a top with a restricted flow mouthpiece in order to prevent large spills while a child learns to hold and maneuver a regular cup.

[0006] While “sippy cups” have become widely popular, they suffer from several disadvantages. First, they require advanced planning and preparation on the part of parents, since “sippy cups” do not come pre-filled with a beverage product. Since “sippy cups” are generally not disposable, they are not as sanitary as a fresh, disposable cup, and empty or partially unused cups must be retained for cleaning and re-use. Also, replacing lost or worn out cups can be costly.

[0007] Several pre-filled disposable products are available for children, but each of these has certain drawbacks associated with it. Disposable juice boxes and bags employ a straw to provide access to the beverage product stored inside. Children making the transition from bottle to cup likely have not yet learned to use a straw, and thus a straw may present a hazard to children of this age group. Also, these beverage products are prone to leaks and spills due to the soft structure of the boxes and bags and the lack of a seal around the straw.

[0008] Therefore, a substantial need exists for a pre-filled disposable beverage container suitable for use by children making the transition from bottle to cup.

BRIEF SUMMARY OF THE INVENTION

[0009] The present invention generally relates to disposable beverage containers and, more particularly, relates to a disposable children's cup which is pre-filled with a beverage and marketed as a ready-to-drink product.

[0010] According to the preferred embodiments of the present invention, pre-filled disposable beverage containers are provided which are suitable for use by children making the transition from bottle to cup. The disposable beverage containers use a top with a mouthpiece which provides a restricted liquid flow in order to prevent excess spillage while allowing a child to gain a feel for drinking from a standard cup. These containers are pre-filled with an appropriate beverage product in order to provide a complete, ready-to-drink product which children can consume and then discard.

DETAILED DESCRIPTION OF THE INVENTION

[0020] FIG. 1 illustrates the first embodiment of the present invention with the mouthpiece 105 in the up position. The pre-filled disposable beverage container 101 consists of a liquid housing 102 and a top 104. The beverage container 101 would be molded so that the liquid housing 102 and top 104 form one single piece. The mouthpiece 105 is a snap-in turret style mouthpiece with an integrated straw that can flip up for restricted flow drinking or down to keep the liquid inside. The liquid is filled through the bottom 103 of the container.

[0021] FIG. 2 which is a broken away perspective view of the top 104 of the first embodiment container with the mouthpiece 105 in the recessed position and with a safety seal 106. This seal protects tampering with the contents and keeps the mouthpiece 105 sanitary. Such safety seals are well known, and will be recognized by those having ordinary skill in the art.

[0022] FIG. 3 illustrates a plan view of the top of the first embodiment with the integrated straw mouthpiece 105 in the up position and attached to the top 104. It is noted that the mouthpiece 105 is shown with one large hole 109 in which the liquid passes through. There is the possibility of a variety of hole sizes or even a series of small holes that may be more preferable to a particular manufacturer.

[0023] FIG. 4 illustrates a cut away view of the inner components of the first embodiment of beverage container 101. The housing 102 is pre-filled with liquid through a hole in the bottom 103. A plastic cover is then sealed over the bottom 103 to keep the liquid inside housing 102. As the beverage container is disposable, it is not necessary to fill it again. The top 104 of the beverage container 101 is molded to the housing 102. A snap-in turret style mouthpiece 105 contains an integrated straw feature 108 which allows for restricted flow of liquid through the liquid housing 102. When the mouthpiece 105 is in the up position the integrated straw 108 allows for easy flow of liquid. An additional hole 107 is needed to allow for the free flow of liquid through the straw 108.

[0024] One drawback of “sippy cups” noted earlier is the tendency for the cups to leak. FIG. 5 illustrates a cut away view of the integrated straw 108 of the mouthpiece 105 crimped shut as to keep the liquid from leaking through the mouthpiece 105.

[0025] FIG. 6 is a cross-sectional, partially cutaway view of a bottom portion 114 of container 101. In the center thereof is a cylindrical shoulder 115 with a hole 114 in the center thereof. Though this hole 114 container 101 can be pre-filled with a liquid, as shown in FIG. 6. Once filled, hole 114 can be sealed by heat-sealing shoulder 115. By this method, or others known to those of skill in the art, a pre-filled, sanitary disposable cup can be provided.

[0026] FIG. 7 illustrates a second embodiment of the pre-filled disposable beverage container 101 with the integrated straw mouthpiece 105 in the up position. The liquid housing 102 is separate from the top 104. The top 104 is constructed as to include the integrated straw mouthpiece 105. The top 104 is attached to the liquid housing 102 by a snap on cap 112. The mouthpiece 105 would allow for restricted flow of beverage from the liquid housing 102. While the shape of the second embodiment of the beverage container is wide at the bottom and thinner at the top, it is noted that any variety of shapes may be employed. The exact shape of the beverage container 101 is not essential to the invention, and will purely be a choice of the particular manufacturer. Similarly, the size of the liquid housing 102 in relation to top 104 is simply a choice of the particular manufacturer and not essential to the invention. The top is thinner in this second embodiment beverage container 101 only for the ease of filling during manufacturing.

[0027] It is noted that a safety seal in the second embodiment would be the same as the safety seal 106 in FIG. 2 of the first embodiment. All that would seem necessary is a peel away seal at the top of the mouthpiece 105. However, any additional safety seals or variations therein would be determined by the manufacturer.

[0028] FIG. 8 shows the second embodiment of beverage container 101 broken into components. The snap-on cap 112 has a rim 109 around the top 104 which would mate with and snap over circumferential shoulder 110 of the housing unit 102. This would create a seal between the top 104 and the housing unit 102 to keep the liquid inside the beverage container 101. This figure also illustrates the components of the integrated straw mouthpiece 105. The straw 108 is integrated into the mouthpiece 105 so liquid flows through the straw 108 only. Therefore, if the mouthpiece 105 is up or down determines the flow of liquid.

[0029] FIG. 9 illustrates an up close view of the top 104 of the second embodiment of the beverage container 101. The mouthpiece 105 is a turret style mouthpiece which snaps in to the top of the cup 104. The integrated straw 108 rests inside the mouthpiece 105.

[0030] Both disposable beverage containers herein described may be formed of a variety of materials. Plastic provides several advantages, since it is readily available, easy to shape and recyclable if the proper grade is selected. Plastic would also allow for the heat seal over the bottom where the liquid is filled in the first embodiment, as shown in FIG. 6.

[0031] In a preferred embodiment, container 101 is pre-filled with a beverage, preferably for use by a child. In mass-producing the containers, each can be filled and sealed, for example, as described above with respect to FIG. 6. The container 101 may be a single piece as shown with reference to FIGS. 1 and 4, or may be two-piece as shown in FIG. 8. If a one-piece construction, container 101 may be blow-molded or otherwise formed as is known by those of skill in the art. If container 101 is of a multi-piece construction, it is preferably comprised of base 102 having a rim 110 which is designed to matingly engage a lip 109 of a top portion 104. As shown in FIG. 8, the container 101 is completed by press fitting top 104 over rim 110 to form a permanent and liquid-tight seal which may not be broken unless destroyed. In this manner, an inexpensive, easily made and pre-filled container 101 may be manufactured.

[0032] While the first embodiment beverage container 101 is shown in a specific cylindrical shape, it is noted that the beverage container 101 could take on any variety of shapes or sizes. The exact shape of the beverage container 101 is not essential to the invention, and will be purely a choice of a particular manufacturer. Similarly, the size of the liquid housing 102 in relation to the top 104 is simply a choice of a particular manufacturer.

[0033] While the invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
