Description




FIELD OF THE INVENTION




The present invention relates to containers and, in particular, to a spherical or semispherical anti-tipping container for liquid and semi-solid foods.




BACKGROUND OF THE INVENTION




There are a wide variety of containers on the market for storing and dispensing liquid and semi-solid foods. Many of those containers, however, are not designed to minimize or prevent tipping. As a result, the contents in the containers can easily spill. This is a prevalent problem with infants, toddlers, physically handicapped individuals, the elderly and the infirmed. In certain cases spillage can be harmful, for example, if the liquid or food item is hot. Even relatively warm contents can be harmful to infants and the infirmed.




To prevent this, some containers have been designed with wide, flattened bottoms which stabilize the container while it is resting on a table or other flat surface, thus minimizing the likelihood of the container tipping over. These types of prior art containers do not, however, provide any ability to self-right the container in the event that the container is dropped. Hence, spillage is still possible, and with infants and the infirmed, is highly likely.




A need therefore exists for an improved container which minimizes spillage and is easy to hold.




SUMMARY OF THE INVENTION




An object of the invention is to provide a container that minimizes spillage and is easy to hold for individuals with limited dexterity, such as infants, toddlers, the infirmed and the physically handicapped.




This and other objectives and advantages are provided by a container made in accordance with the present invention that can be easily held in a human hand by cupping or grasping depending on the person's dexterity. The container includes at least a rounded or semi-spherical bottom portion and, more preferably is substantially spherical in shape.




A counter-weight is formed or located in the bottom and is configured to self-right the container in the event the container tipped, thus preventing liquid from coming out of the container's dispensing or drinking top. The anti-tipping aspect of the invention also prevents the drinking top from touching any surface upon which the container is placed, thus making it more hygienic. The counter-weight may be permanent or removable.




In one aspect of the invention, the counter-weight is made of a material that absorbs thermal energy (i.e., heat and/or cold) so that it can be heated and/or cooled, thus providing a mechanism for maintaining the contents of the container at a desired temperature.




The container may include a removable top or lid which permits the use of a wide variety of drinking tops, including a rubber nipple, sipping spout, pop-up sports spout, or straw. The present invention also contemplates the use of a utensil lid which includes a fork and/or spoon for serving semi-solids from the container.




The container is preferably made from a shatterproof material, such as plastic, with antibacterial properties, and may be opaque, translucent or transparent.




A translucent level window may be included to assist in viewing the level of the contents within the container.




The foregoing and other features and advantages of the present invention will become more apparent in light of the following detailed description of the preferred embodiments thereof, as illustrated in the accompanying figures. As will be realized, the invention is capable of modifications in various respects, all without departing from the invention. Accordingly, the drawings and the description are to be regarded as illustrative in nature, and not as restrictive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to the drawings, wherein like reference numerals illustrate corresponding or similar elements throughout the several views,

FIG. 1

depicts one embodiment of a container according to the present invention intended to be used for dispensing liquids and semi-solids to infants, toddlers, children, teenagers, adults, the infirmed, and physically handicapped. Container


10


preferably includes a body


12


, that includes at least a partially rounded or semi-spherical bottom or base portion


24


. More preferably, as shown in the figures, substantially all of the body


12


is formed in a semi-spherical shape. It is also contemplated that the shape might be oblong as opposed to perfectly semi-spherical. The use of a shape with a rounded bottom permits the bottle to be self-righted as will be discussed below. Also, the rounded shape makes the bottle more intriguing and playful for a young child and is easy to grasp.




The container also includes a lid


14


that is attached to the body


12


as described herein. The lid


14


includes a dispenser which is generally depicted by the numeral


15


. A wide variety of dispensers


15


can be used in the present invention, for example, a conventional nipple


26


(FIG.


1


), a sipping spout


66


(FIG.


6


), a pop-up sports spout (FIG.


8


), a straw (FIG.


9


), or a utensil (FIG.


10


). The dispensers


15


may be formed integral with the lid


14


or be removably attached.




The body


12


and lid


14


may be made from a variety of materials and may be transparent, translucent or opaque. The body


12


and lid


14


are preferably formed from a molded antibacterial plastic. Antibacterial material is preferred in order to prevent transmission of bacteria to the contents. One suitable antibacterial material is plastic material that incorporates Microban® resin. Microban® resin is an antibacterial resin material sold by Microban Products Company, Charlotte, N.C. The molded plastic may be brightly colored, metallicized, or rubber-coated in order to provide an attractive and/or useful exterior for the intended user. To the extent the body


12


is opaque and the contents cannot be viewed, a translucent or transparent fluid-level window


16


may be incorporated. The window and/or body may include fluid-level markings


18


which indicate the level of the contents within the container


10


.




As shown is

FIG. 2

, the body


12


and the lid


14


have outer surfaces


20


,


22


that enable the container


10


to be easily gripped or cupped by an adult or child's hands with varying degrees of dexterity. The outer surface may be a coating applied to the material of the body


12


or lid


14


, such as a plastic or rubber material. The outer surface can be made from material that minimizes thermal conduction, thereby assisting in maintaining the contents at a desired temperature and minimizing discomfort to the user. Alternately or in addition to the coating, the outer surfaces


20


,


22


may be textured to decrease the chances of the container


10


slipping out of a user's hands.




In addition, the outer surface


22


of the lid


14


is preferably shaped so that it gently curves away from the user's face to facilitate drinking from container


10


. Preferably the lid


14


is similarly shaped as the body


12


so that it continues to form a semi-spherical shaped container as illustrated. This is particularly beneficial for infants and toddlers as it assists in providing the container


10


with an amusing and entertaining appearance.




The lid


14


may be made from material that is different than the body


12


. Preferably the outer surface


22


of the lid


14


is soft and dimpled which allows the user's saliva to drain away from the mouth, thereby reducing saliva irritation.




Body


12


may optionally include handles


13


(shown in broken lines in

FIG. 2

) located on outer surface


20


. The handles


13


make container


10


easier to hold and can be any convenient shape and size. The handles can be integrally formed or separately attached to the container. Also, the handles


13


can extend out from the sides of the container


10


as shown or may be made as depressions or apertures formed within the body


12


.




The body


12


also includes a counterweight or anti-tip weight


28


located in the base portion


24


or suspended within container. As discussed above, the container


10


has a rounded base


24


. The rounded base


24


allows the container


10


to wobble when placed on a flat surface (not shown). The counterweight


28


is positioned and weighted so that, acting in combination with the container's rounded base


24


, it causes container


10


to self-right when the central axis


200


of the dispenser


15


is at an angle with respect to a vertical axis. This self-righting or anti-tipping configuration prevents or minimizes the occurrence of the dispenser


15


touching a surface upon which the container


10


may be placed. The wobbling aspect of the invention also is beneficial for engaging the user's imagination.





FIG. 3

illustrates the bottom of the body


12


. The counterweight


28


may be engaged directly into the container


10


, preferably so that it is centrally located in to base


24


. If the weight


28


is attached directly to the container


10


, it is preferably shaped so that, in combination with the base


24


, it defines a semi-spherical or rounded surface. More preferably, the counterweight


28


is located within a cavity formed in the base


24


(shown in FIG.


5


). A cap


30


is attached to the base to retain and/or secure the counterweight


28


to the base


24


. Counterweight


28


can be formed of any suitable material and should have a weight that is sufficient to prevent tipping of a container filled with liquid or semi-solid food. Preferably, the counterweight is made from a material which absorbs thermal energy (i.e., absorbs heat and/or cold), such as a thermal gel. Thermal gels are well known. One type of thermal gel that is suitable is a water and propelene glycol mixture, such as TheraFlex sold by ColdIce Inc. of Oakland, Calif. or TemTro™ sold by TemTro, Inc. of Alpharetta, Ga. Inert and/or non-toxic materials are preferable so as to minimize any safety risk to the user should the counterweight


28


become exposed.




The counterweight


28


can be formed in any convenient shape. In the embodiment illustrated in

FIG. 5

, counterweight


28


is cylindrical in shape. Such a shape is preferable in a rounded container since it counters tipping in all directions equally. As discussed above, the counterweight can also be suspended within the container, such as by attachment to the interior walls of the body


12


or attachment to and suspended down from an interior surface of the lid


14


. It is further contemplated that the counterweight


28


may be located between the interior and exterior surfaces of the body


12


. In such an embodiment, the location and/or structure of the container is preferably configured to facilitate heating/cooling of the contents more readily than the heating/cooling of the outer surface.




Referring now to

FIG. 5

, the counterweight


28


is preferably contained within an inverted cup-shaped recess


32


that is formed in the base


24


of the body


12


. The recess


32


should be sized and shaped as to receive the counterweight


28


and prevent or limit movement of the counterweight. The cap


30


is preferably made of the same material and colored the same as the body


12


, although it need not be so. The cap


30


may be secured by any convenient means. In one embodiment, which is preferable for small children such as infants, the cap


30


and/or the counterweight


28


is fixedly attached so as to prevent any choking hazard. In another embodiment, the cap


30


includes a groove


34


that engages with a tongue


36


formed in the base


24


of the body


12


. In this embodiment, the cap


30


would be press-fit into the base


24


such that the groove


34


engages with the tongue


36


. The cap


30


and/or counterweight


28


could, alternatively, be threaded onto the base


24


.




While the recess in the embodiment of

FIG. 5

is shown formed in the body


12


, it is also contemplated that the counterweight


28


may be attached directly into an opening formed in the base


24


. In that embodiment, the attachment of the counterweight must be such that no leakage occurs.




As shown in

FIG. 5

, the body


12


includes an upper portion


38


and a substantially semi-spherical or rounded lower portion


40


. The lower portion


40


defines a cavity


42


, which is intended to retain the liquid or semi-solid food. The spherical or rounded shape of the lower portion


40


naturally reduces the amount of air ingested by a user drinking from the container


10


since most of the volume may be filled with liquid, thereby displacing the air within the container


10


. The upper portion


38


of the body


12


includes a mouth


44


that allows the fluid to flow from the cavity


42


into the dispenser


15


(which in the illustrated embodiment is a nipple


26


.) The upper portion


38


also includes a preferably substantially flat annular surface


46


that connects the mouth


44


to the lower portion


40


. The body


12


also includes an elbow


49


that provides the transition between the flat surface


46


and the lower portion


40


.




The mouth


44


is preferably cylindrically shaped and terminates at a rim


50


. The mouth


44


preferably includes threads


48


or similar attachment mechanisms for removably receiving the lid


14


.




The lid


14


preferably includes a rim


56


from which downwardly depends a cylindrical portion


52


. The cylindrical portion


52


preferably includes threads


54


which threadingly engage or mate with the threads


48


formed on the mouth


44


. As such, the lid


14


is secured to the mouth


44


by rotating the lid


14


in one direction relative to the mouth


44


, and may be removed by rotating the lid


14


in the opposite direction relative to the mouth


44


.




The dispenser


15


is preferably removably attached to the lid


14


. By making the dispenser removable, the dispenser can be easily replaced is it becomes damaged or worn. Furthermore, the dispenser


15


can be changed to suit the needs of the user, thereby permitting the same container to be used over many years and by different users.

FIG. 5

illustrates the use of a conventional rubber nipple


26


. The nipple


26


preferably includes a head


58


, a lip


60


and a constriction


62


. The head


58


includes an aperture


64


that allows liquid to flow therethrough. The constriction


62


is adapted to removably engage the rim


56


of the lid


14


as shown, thereby securing the nipple


26


to the lid


14


. When lid


14


is secured to the mouth


44


, the lip


60


is preferably positioned between the rim


50


of the mouth


44


and the rim


56


of the lid


14


, thereby creating a compression seal for preventing leakage.





FIG. 6

shows another embodiment of the container


10


. In this embodiment the container lid


14


has a sipping spout


66


which is intended for use by toddlers or more mature infants. The sipping spout


66


is preferably formed of rigid or flexible plastic and includes a head


68


, a lip


70


and a constriction


72


. As in the prior embodiment shown in

FIG. 5

, the rim


56


of the lid


14


is received within the constriction


72


and the lip


70


forms a compression seal when the lid


14


is secured to the mouth


44


. The head


68


of the sipping spout


66


preferably includes a plurality of apertures (three shown and designated


74


,


76


, and


78


), which allow liquid to pass through the sipping spout


66


more easily than the nipple


26


.





FIG. 7

shows another embodiment of the container


10


. In this embodiment, a sealing disc


80


is included. When in use, the sealing disc


80


is positioned between the rim


56


of the lid


14


and the rim


50


of the mouth


44


, thereby preventing passage of fluid from the cavity


42


out of the container


10


. The sealing disc


80


is intended to be used when the container


10


is being stored or transported in order to prevent leakage. As shown in

FIG. 7

, the nipple


26


may be inverted and placed between the sealing disc


80


and the rim


50


of the mouth


44


.





FIG. 8

illustrates another embodiment of container
