The present invention relates to containers for mixable powders or liquids generally.
There are many situations when a mixable powder needs to be mixed with water. For example, powdered medicines, such as antibiotics, are mixed with sterile water in a medicine bottle. In another example, baby formula is added to sterile water in a baby bottle.
Many products and patents exist to enable these powders to be mixed. Some store the powders separately from the bottles or containers while others provide a two section bottle with a mechanism to add the powder to the liquid. One such mechanism breaks a barrier between the two sections, another pushes a surface out of the way.
There is therefore provided, in accordance with a preferred embodiment of the present invention, a removable container for powder or liquid. The container includes a housing, a spilling mechanism and a bypass element. The housing hangs within a bottle on a rim of the bottle and is capable of storing the powder or liquid within the bottle. The housing is sealed from a precursor liquid held within the bottle. The spilling mechanism enables the powder or liquid to spill out of the housing and into the precursor liquid. The bypass element provides the precursor liquid out of the bottle without mixing with the stored powder or liquid.
Moreover, in accordance with a preferred embodiment of the present invention, the container also includes release elements to provide an exit path for steam.
Further, in accordance with a preferred embodiment of the present invention, the container also includes circulation elements to enable the precursor liquid to mix with the powder or liquid.
Still further, in accordance with a preferred embodiment of the present invention, the bottle includes a nipple and the spilling mechanism includes a cap shaped to be pressed down through the nipple.
Moreover, in accordance with a preferred embodiment of the present invention, the housing includes an open-ended canister having an upper lip to which a flexible cap is snap-fittable, the upper lip to rest on the rim and a bottom snap-fittable into a lower end of the open-ended canister. The spilling mechanism also includes a rod, integrally formed with the bottom, which rod is snap-fittable into the flexible cap. The bottom is pushably releasable from the open-ended canister when pushed, via the rod, by the flexible cap thereby to release the powder or liquid into the bottle.
Further, in accordance with a preferred embodiment of the present invention, the removable container also includes a rubber ring to seal the bottom to the open-ended canister. The rubber ring can be connectable to the bottom or to the canister.
Furthermore, in accordance with a preferred embodiment of the present invention, the housing includes a ring having an upper lip to which the flexible cap is snap-fittable. The upper lip rests on the rim. The spilling mechanism includes a closed canister connectable to the ring and a piston, which piston is snap-fittable into the flexible cap. The closed canister is pushably releasable from the ring when the closed canister is pushed by the piston cap thereby to release the powder or liquid into the bottle.
Further, in accordance with a preferred embodiment of the present invention, the powder or liquid can be a nutritional formula, a powdered chemical, or a medicine.
Still further, in accordance with a preferred embodiment of the present invention, the spilling mechanism includes a flat cap.
Moreover, in accordance with a preferred embodiment of the present invention, the spilling mechanism includes a flat-bottomed cap to press said powder or liquid out of said liquid.
There is also provided, in accordance with a preferred embodiment of the present invention, a removable container for powder or liquid which includes a canister, a flexible cap and a release mechanism. The canister is capable of sealingly storing an amount of powder or liquid and includes multiple elements connectable together. The elements include at least an upper lip to rest on a rim of a bottle. The flexible cap is snap-fittable into an upper end of the canister. The release mechanism separates at least two of the multiple elements of the canister when the flexible cap is pushed into the canister thereby to release the powder into the bottle.
There is also provided, in accordance with a preferred embodiment of the present invention, a method for creating a solution from a powder or a liquid. The method includes placing a removable container storing the powder or liquid onto the rim of a bottle of precursor liquid, pressing down on a cap forming part of a spilling mechanism of the removable container to push the powder or liquid down into the bottle, the pressing causing elements of the spilling mechanism to fall into the bottle, shaking the bottle with the elements therein thereby to mix the solution and drinking the solution from the bottle with the elements within the bottle.
Further, in accordance with a preferred embodiment of the present invention, the method also includes having release elements in said removable container to provide an exit path for steam.
Finally, in accordance with a preferred embodiment of the present invention, the method also includes having circulation elements to enable said precursor liquid to mix with said powder or liquid.
The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of operation, together with objects, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings in which:
It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements.
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.
Applicants have realized that adding powder or liquid to a bottle of liquid is an awkward process. This is particularly true for adding baby powder to a baby bottle full of water. Moreover, there is a need to create such a mixture when traveling, particularly in order to keep the mixture fresh.
Applicants have realized that a removable container which may store powder within a bottle and may release it into the bottle when desired may be advantageous. Powder may be placed in the removable container of the present invention prior to traveling and prior to placing the container into the bottle. The removable container may be removed after use for cleaning and for refilling. Moreover, removable powder container 12 may not be specific to a particular type of bottle and may be moved between bottles.
The following discussion presents the present invention for storing and dispensing powder. It will be appreciated that the present invention may also be utilized for storing liquids to be dispensed at a later time. It will also be appreciated that the present invention may also be used for other types of powders or liquids, other than those for baby bottles. For example, for sports drinks, powdered medicines or industrial powders. It may be particularly useful for powders that create solutions that do not maintain their freshness for very long and/or for those which need to be utilized shortly after mixing and thus, need to be dissolved just prior to utilizing, such as, for example, baby formula or other nutritional formula, a powdered chemical or medicine, such as anti-biotics.
The embodiment below shows a baby bottle; however, it will be appreciated that the present invention is operable with other types of bottles and containers as well.
Reference is now made to
Open-ended canister 20 may be of any suitable size (the size shown in the figures is exemplary only) and may be formed of any suitable material which may be waterproof, such as a hard or semi-hard material, and may comprise an upper lip 30, designed to sit on a rim 16 (
Open-ended canister 20 may have a flexible ring 33 formed at the distal end from lip 30, where flexible ring 33 may be formed of any suitable flexible material, such as rubber or silicon. Flexible ring 33 may be connected to canister 20 in any suitable way, such as by co-injection, gluing, over-molding, snapping, mechanical attachments, etc.
Bottom 22 may be formed of any inflexible material, such as resin (ABS (Acrylonitrile Butadiene Styrene), PP (Polypropylene)), metal, etc., and may comprise a rod 34, a ball 36 on top of rod 34 and a base 38 having a ring-shaped indentation 39 around it. As described in more detail hereinbelow, bottom 22 may be snap-attachable into flexible ring 33 of open-ended canister 20, thereby to provide a sealed bottom to container 12.
Flexible cap 24 may be formed of any suitable soft and/or flexible material, such as rubber, silicon, TPR (ThermoPlastic Rubber), and may be integrally formed of a conic top 40 sitting within a crown 42. Flexible cap 24 may also have a ring-shaped indentation 45 toward the bottom of crown 42 which may provide a snap connection and upper seal to open-ended canister 20.
Reference is now made to
Once the open container is sufficiently filled (
When the user presses flexible cap 24 into open-ended canister 20, thereby to close canister 20, ball-shaped indentation 46 may snap onto ball 36, thereby to hold it, and rod 34, in place. At generally the same time, ring-shaped indentation 45 may snap onto inwardly-protruding neck ring 48, thereby to provide an upper seal to open-ended canister 20, as shown in
Reference is now made to
It will be appreciated that, in this state, powder 50 may be sealably stored within container 12 even though container 12 may be surrounded by liquid 60. Moreover, despite the fact that container 12 may enclose the opening of bottle 10, liquid 60 may still flow to and from nipple 14, as shown in
As shown in
The user may then shake bottle 10 to mix liquid 60 and powder 50, as is generally known, before providing bottle 10 to a child to drink. The released elements of container 20, which may move around during shaking, may help powder 50 to dissolve into liquid 60.
The child may tip the bottle, as shown in
It will be appreciated that the present invention may provide a removable container for powder or liquid that may keep the powder or liquid fresh until it needs to be used. Moreover, mixing the powder or liquid is simple and straightforward, even in awkward situations.
Removable container 20 may fit onto multiple types of bottles since it has no threading to attach to bottle 10; instead, it merely hangs within bottle 10, storing powder 50 (or a liquid) but keeping it sealed from precursor liquid 60 within bottle 10. Despite the fact that container 20 may occupy the mouth of bottle 10, container 20 may include bypass elements to provide liquid 60 out of bottle 10 without mixing with stored powder 50. And container 20 may also include a release element to provide an exit path for steam which may be generated if hot water is placed into bottle 10 and circulation elements to help liquid 60 to mix well with powder 50 so that no chunks of powder remain after mixing. The circulation elements may include holes 32 and the actions of rod 34, base 38 and flexible cap 24 which fall into bottle 10 as well as the fact that powder 50 falls into bottle 10 from generally its top area. Rod 34, base 38 and flexible cap 24 are thus free to move around in bottle 10 and aid in pushing powder 50 out of container 20, as well as in circulating powder 50 and in helping it to dissolve into liquid 60.
It will be appreciated that removable container 20 may also comprise a spilling mechanism, which may comprise flexible cap 24 and other elements, to enable powder 50 to spill out of the housing and into liquid 60. Spilling mechanism may operate through nipple 14, such that the user may press down on flexible cap 24 through nipple 14. Reference is now made to
Ring 124 may have similar elements to the upper section of open-ended canister 20 of the previous embodiment. Thus, ring 124 may comprise upper lip 30, holes 32 and inwardly-protruding neck ring 48. In addition, ring 124 may comprise a ring-shaped indentation 132 on its outer surface.
Canister 120 may snap-connect to ring 124 (via an inwardly-protruding tip 131 on canister 120 and ring-shaped indentation 132 on the outer surface of ring 124,), thereby to produce a canister to receive flexible cap 24 and to sit on rim 16 of bottle 10. The resultant canister may be sealed with inwardly-protruding ring 130, formed of an elastic material such as rubber or silicon), as shown in
Piston 122 may comprise rod 34, ball 36 and a base 138 and may be placed inside of canister 120, as shown in
With piston 122 inside of canister 120, powder 50 may be added and flexible cap 24 may be placed onto the canister-ring combination. As in the previous embodiment and as shown in
Since canister 120 is closed, the powder isn't released from the bottom of container 112. Instead, as shown in
Reference is now made to
In this embodiment, the powder container, labeled 212 in the expanded view of
Open-ended canister 220 may include a protruding ring 234 at the bottom thereof, onto which sealing rings 232 may rest (as shown in
The remaining elements of powder container 212 may be similar to those of the first embodiment of
Reference is now briefly made to
In this embodiment, base 228 may be connectable to the bottom of open-ended canister 220, as in the previous embodiment. However, in this embodiment, powder 50 may provide the connection between cap 224 and base 228, rather than rod 34, and therefore, when cap 224 is pushed into canister 220, powder 50 may push base 228 out of canister 220, thereby releasing powder 50.
Reference is now made to
Caps 324 and 424 may be flat, rather than conic, so as to fit within a bottle which has a flat cover. When the user may want to mix the powder with the liquid in the bottle, the user may remove the cover of the bottle and may push down flat cap 324/424 into its canister 20/120/220.
In an alternative embodiment, the cap may be formed of a hard material, rather than a flexible one. In this embodiment, canister 20/120/220 may include a ring of flexible material into which the hard cap may be inserted, so as to provide a strong seal therebetween.
In a further alternative embodiment, the spilling mechanism may be any suitable mechanism which will cause powder 50 to spill out. For example, the connection between cap 24 (whether hard or flexible) and rod 34 may be through any suitable snap arrangement rather than via ball 36, or rod 34 may have a flat surface touching cap 24 or any other mechanism.
It will be appreciated that the present invention stores powder or liquid in a removable container which may sit inside bottle 10 and may be sealed from liquid 60 within bottle 10. The removable container may comprise multiple elements which are releasably connected to form the container and a release mechanism to release the connections when pushed by the cap, thereby releasing the powder into the bottle.
While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
