Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to liquid containers, and in particular, to a non-spill container.




2. Description of the Related Art




Bubble producing toys and devices are very popular with children. A wide variety of such bubble producing toys are now available in the market. Despite this widespread variety, the most basic form of a bubble producing toy is a wand that has a handle at one end and a loop at a second end. The loop is dipped into a bubble solution (which is usually soap) so that a film of the bubble solution extends across the area of the loop. The child can then blow at the loop to create bubbles.




The use of this wand and its loop requires that the loop be continuously dipped into the bubble solution to create more bubbles. Therefore, the container for the bubble solution must provide sufficiently convenient access to the user for continuous dipping of the wand and its loop.




Another important characteristic that the bubble solution container must have is that it should guard against spills. Since most bubble solution is made from soap, spills can be very messy. A number of spill-proof or non-spill containers have been provided to guard against spills of liquids stored therein. An example of a non-spill container is illustrated in U.S. Pat. No. 5,105,975 to Patterson, which provides a top member that is releasably mounted to a bottom member. A tube extends through an opening in the top member. The volume of the bottom member is provided to be smaller than the volume of the top member so that the liquid contained in the bottom member is prevented from entering the tube when the container is tipped. Unfortunately, the container in U.S. Pat. No. 5,105,975 is not completely spill-proof, and leakage is still possible.




In light of the above, there still remains a need for a container that effectively prevents the liquid stored therein from being spilled.




SUMMARY OF THE INVENTION




It is therefore an object of the present invention to provide a container that effectively prevents the liquid stored therein from being spilled.




It is another object of the present invention to provide a container that provides convenient continuous access to the liquid stored therein.




The objects of the present invention may be achieved by providing a container having a container body that has an inner chamber, a bottom wall, a top wall, a opening provided in the top wall, and a tube extending from the opening into the inner chamber to provide communication between the inner chamber and the exterior of the container body.




In one embodiment, the opening can be curved.




In another embodiment, the tube can have a curved cross-section.




In yet another embodiment, the tube can be positioned offset from the center of the inner chamber.




The container body can include a cup-like lower body that receives liquid therein and has an open upper mouth. The container body can also include an inverted cup-like upper body having an open lower mouth. The upper body is removably connected to the lower body with the open mouths thereof in communication with each other to form the inner chamber. The container can also include a lid pivotably coupled to the top wall and covering the opening, and a stopper inserted through the opening.




Thus, the pivotable lid covers the opening, and retains the stopper securely in place so as to prevent liquid from exiting through the opening. The stopper can be easily and conveniently removed from the opening to allow the user with quick and convenient access to the liquid stored in the interior of the container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.




The present invention is applicable to all containers that hold or otherwise retain liquid. Such containers can be used to hold any type of liquid, where the liquid needs to be dispensed using a wand, a tong, or other dispensing device. Thus, the container can be used to hold bubble solution for use with a bubble producing toy, or it can be used to hold medicine, detergent or other liquids.




The present invention provides a non-spill container having an opening through which a stopper may be inserted. A pivotable lid is positioned over the opening to cover the opening, and to retain the stopper securely in place so as to prevent the liquid from exiting through the opening. The stopper can be easily and conveniently removed from the opening to allow the user with quick and convenient access to the liquid stored in the interior of the container.





FIGS. 1-7

illustrate one embodiment of a non-spill container


20


according to the present invention. The container


20


has a lower body


22


defining an interior chamber


24


, and an upper body


26


that is removably connected to the lower body


22


. The lower body


22


is cup-like in that it is generally cylindrical, has an open mouth and has a bottom wall


28


. The top


30


of the lower body


22


has an upper annular flared rim


32


having external threads


34


, with the upper flared rim


32


defining the open mouth. The upper body


26


is also generally cylindrical with an inverted cup-like configuration, and has a lower annular flared rim


36


that has internal threads


38


. The lower flared rim


36


has a slightly larger diameter than the upper flared rim


32


so that the lower flared rim


32


of the lower body


22


can be received inside the upper flared rim


36


of the upper body


26


. The upper body


26


also has a top wall


40


, with an elongated opening


42


provided in the top wall


40


. A border ridge


44


surrounds and defines a well region that includes the opening


42


. The well region has a ledge


50


that is adapted to engage or receive an extension


52


of a stopper


54


. The well region also has an angled inner surface


56


that is adapted to engage an angled lower edge


58


of the stopper


54


. A hood


60


is provided above the top wall


40


and cooperates with a lid


62


to cover the well region. The hood


60


is also smaller than the lid


62


so as to act as a guide over which the lid


62


can be pivoted (see FIGS.


2


and


4


). The hood


60


has two side walls


64


and a rounded top wall


66


.




A lid


62


is pivotably secured to the border ridge


44


. The lid


62


has two side walls


68


and a rounded top wall


70


. Each side wall


68


has a rounded lower point


72


. Pivot points


74


and


76


can be provided on opposite longitudinal edges of the ridge


44


. A small bearing point (not shown) is provided between each pivot point


74


or


76


and the corresponding rounded lower point


72


to allow the points


72


of the lid


62


to pivot about these pivot points


74


,


76


from a completely closed position, shown in

FIGS. 1 and 3

, in which the lid


62


combines with the hood


60


to completely enclose the well region and the stopper


54


, to a completely opened position, shown in

FIGS. 2 and 4

, in which the lid


62


is seated over the top of the hood


60


to expose the stopper


54


. The top of the ridge


44


defines a stop surface for the pivoting lid


62


in the closed position, and a groove


78


provided in the top wall


40


adjacent the hood


60


defines a stop surface for the pivoting lid


62


in the opened position. Ridges or bumps


84


can be provided on top of the lid


62


to facilitate gripping by the user.




A tube


80


extends from the opening


42


in the top wall


40


into the interior of the upper body


26


. The tube


80


functions as a guide for the stopper


54


. The tube


80


can have a generally rectangular configuration that is adapted to receive the generally rectangular cross-section of the stopper


54


. Even though the tube


80


is illustrated as being rectangular in cross-section, it is possible to provide the tube


80


in any desired configuration. For example, as shown in FIG.


14


and as described in greater detail hereinbelow, the tube


80


can have a generally oval or elongated curved configuration. The tube


80


can extend for any desired length into the interior of the container


20


. For example, as shown in

FIGS. 3 and 4

, the tube


80


can extend for a length that is about the same as the length of the upper body


26


, so that the lowermost end


82


of the tube


80


extends to the region where the rims


32


and


36


are located. Alternatively, the tube


80


can extend for a length that is less than the length of the upper body


26


, or for a length that is greater than the length of the upper body


26


so that the lowermost end


82


is positioned inside the interior chamber


24


of the lower body


22


.




The lower body


22


and the upper body


26


can be made from the same material, or from different materials. Possible materials for the lower body


22


and the upper body


26


can include plastic, acrylic, metal, glass or certain fabrics. The top wall


40


, hood


60


and tube


80


can be molded or provided in one piece together with the upper body


26


.




The stopper


54


as shown in

FIGS. 1-7

is a bubble producing toy


54


(also referred to herein as a “wand”), and is illustrated in greater detail in FIG.


8


. The wand


54


has a thin shaft


88


having a ring-like loop


90


provided at a first end. The loop


90


has a serratted ring, such that ridges or bumps


92


are provided on the outer surfaces of the loop


90


. The ridges


92


function to hold the bubble solution against the loop


90


to form a solution film that is blown to form the bubbles. The loop


90


can have any desired shape. The other (i.e., second) end of the shaft


88


has a support section


94


that includes a shoulder


95


, a lining


96


, an enlarged gripping handle or blade


98


, and the extension


52


. Specifically, the shoulder


95


is generally triangular and is provided adjacent the second end of the shaft


88


. The lining


96


is provided above the shoulder


95


and functions like a gasket to prevent the liquid stored in the interior chamber


24


from passing therethrough. The lining


96


can be made from rubber, plastic and certain fabrics. The extension


52


is provided above the lining


96


, and protrudes outwardly in one or more directions. The handle or blade


98


is positioned above the extension


52


, and has an angled lower edge


58


adjacent the extension


52


.




Although the bubble producing toy


54


is illustrated as being inserted through the opening


42


to act as a stopper, other stoppers can also be used to seal the opening


42


. For example, the stopper can have the same configuration as the bubble producing toy


54


(i.e., including the shaft


88


, the shoulder


95


, the lining


96


, the enlarged gripping handle or blade


98


, and the extension


52


), but with the loop


90


omitted. With the loop


90


omitted, the shaft


88


can be provided as a hollow tube with the lower end opened, so that the stopper can then be used as a bulb or syringe for drawing medicine stored in the container


20


.




In operation, the lower body


22


and upper body


26


are provided separately. Any liquid (e.g., bubble solution) can be filled into the interior chamber


24


, and then the upper body


26


connected to the lower body


22


by engaging the threads


34


and


38


of the flared rims


32


and


36


, respectively. The lid


62


is now pivoted to the opened position shown in

FIGS. 2 and 4

. The wand


54


is then inserted through the opening


42


so that the loop


90


and a lower portion of the shaft


88


extend through the tube


80


and into the interior chamber


24


of the lower body


22


, with an upper portion of the shaft


88


, the shoulder


95


and the lining


96


retained inside the tube


80


(see FIGS.


3


and


4


). At this time, the extension


52


will engage the ledge


50


, which acts as a stop surface to prevent the wand


54


from being inserted any further into the opening


42


. In addition, the angled lower edge


58


will engage the angled inner surface


56


of the well region, which also acts as a stop surface to prevent the wand


54


from being inserted any further into the opening


42


. At this time, the provision of the lining


96


inside the tube


80


, coupled with the extension


52


engaging and covering the ledge


52


inside the well region, will prevent the liquid inside the container


20


from being leaked or spilled via the tube


80


and the opening


42


. The lid


62


can now be pivoted to its closed position shown in

FIGS. 1 and 3

, with the rounded top wall


70


covering the wand


54


, and more particularly, engaging the top edge


100


of the handle or blade


98


to keep the support section


94


securely positioned over the opening


42


as a further safeguard against leakage through the opening


42


.




To access the liquid stored inside the container


20


, the user merely flips (i.e., pivots) open the lid


62


to the opened position shown in

FIGS. 2 and 4

, grips the handle


98


, and lifts the wand


54


. If the liquid is a bubble solution, then the user can insert the wand


54


back through the opening


42


to access more of the bubble solution to create more bubbles. If the liquid is a medicine, the user can insert the medicine stopper


54


back through the opening


42


to access more of the medicine.





FIGS. 9-13

illustrate another container


120


according to the present invention. The container


120


is essentially the same as the container


20


, except that the upper body


126


of the container


120


has two openings and two corresponding tubes


180




a


and


180




b


. Each opening is provided with its own ridge


144




a


,


144




b


, hood


160




a


,


160




b


and lid


162




a


,


162




b


. The two tubes


180




a


,


180




b


and their respective openings can be positioned side-by-side from the top wall


140


of the upper body


126


. Otherwise, the construction and use of the lower body


122


and the upper body


126


are the same as for the container


20


. The elements in

FIGS. 9-13

that correspond to the same elements in

FIGS. 1-7

are provided with the same numeral designations, except that a “1” has been added before each such element in

FIGS. 9-13

. For example, the tubes


180




a


and


180




b


in

FIGS. 9-13

have the same construction as tube


80


in

FIGS. 1-7

, and so a “1” was added before the “80”.




The two tubes


180




a


,


180




b


of the container


120


are provided to retain two separate wands


154




a


and


154




b


which are illustrated in

FIGS. 12 and 13

, respectively. These two wands


154




a


and


154




b


are identical in construction to the wand


54


, except that the sizes of the loops


1




90




a


and


1




90




b


are different so that each wand


154




a


and


154




b


produces bubbles having different sizes. As a result, the container


120


provides the user with the option of using different wands


154




a


,


154




b


to create differently-sized bubbles.




The configuration of the tubes


80


,


180




a


,


180




b


and the openings


42


can be modified from the rectangular configurations illustrated in

FIGS. 1-13

. Referring to

FIGS. 14 and 15

, the upper body


26




x


can have a generally curved, circular, oval or elliptical border ridge


44




x


, and a generally curved, circular, oval or elliptical opening


42




x


. The ledge


50




x


is also shown in

FIGS. 14 and 15

, and can also be curved, circular or elliptical. In addition, the tube


80




x


and its cavity can also have a generally curved, circular, oval or elliptical configuration. As used herein, the terms “curved”, “circular”, “oval” and “elliptical” all mean that the opening


42




x


and cavity of the tube


80




x


does not have any straight edges. Otherwise, the construction of the upper body


26




x


can be the same as any of the upper bodies


26


and


126


illustrated hereinabove. Similarly, referring to

FIG. 16

, the stopper


54


in

FIG. 8

can also be modified so that the stopper


54




x


now has a generally curved, circular, oval, or elliptical neck


91


positioned below the extension


52




x


to fit inside the similarly configured opening


42




x


. The lining


96




x


can be placed around the neck


91


and assume a similar curved configuration. Otherwise, the loop


90




x


, shaft


88




x


, shoulder


95




x


, and blade


98




x


can be the same as the corresponding elements for the stopper


54


in FIG.


8


.




The curved, circular, oval or elliptical opening


42




x


and tube


80




x


has a curvature that provides several benefits. First, it allows the use of a wide variety of stoppers


54


or


54




x


. While a rectangular opening


42


and the rectangular cavity of the tube


80


allows a narrow or slim-profile stopper


54


,


54




x


to extend therethrough, the narrow profile of the rectangular opening


42


and cavity cannot accomodate stoppers having a shaft


88


or neck


91


that may have wider or different profiles. Second, the curvature makes it easier and more convenient to insert and remove the stoppers


54


,


54




x


because the curvature of the opening


42




x


and tube


80




x


generally increases the width (i.e., minor axis) of the opening


42




x


and tube


80




x


(particularly at the center thereof, making it easier to engage the stopper


54


,


54




x


into the opening


42




x


. Third, the curvature allows the stopper


54


,


54




x


to be provided with curved engaging edges (i.e., the curved neck


91


), thereby reducing sharp edges that may cause injury to the user. For example, rectangular necks


91


would have four sharp edges that can be further sharpened after extended insertion and withdrawal from the tube


80


,


80




x


. Fourth, the curvature of the opening


42




x


provides a better seal when cooperating with the neck


91


and lining


96




x


of the stopper


54




x


. This is because it is easier to match engaging curved surfaces (e.g., matching


42




x


with


96




x


) to better seal the tube


80




x


and prevent spillage of the liquid stored therein. In contrast, engaging rectangular and straight surfaces are more difficult to match and do not provide as effective a seal.




Although the present invention has been described in connection with the preferred embodiments, it will be appreciated by those skilled in the art that modifications can be made and alternatives utilized without departing from the spirit and scope of the present invention. For example, the lid


62


,


162




a


,


162




b


can be provided in any shape or size as long as it effectively covers the stopper


54


,


154




a


,


154




b


and retains the stopper


54


,


154




a


,


154




b


securely at the opening


42


,


42




x.
