Description:
A shaker bottle

FIELD

The present invention relates to a shaker bottle. More particularly, the present invention relates to a shaker bottle for mixing and storing powdered material such as protein powder with a fluid.

BACKGROUND

Specialist sports drinks are becoming increasingly popular for athletes and other individuals who require or desire specialist nutrition either before or after training, or both.

One of the most common drinks is known generally as a protein shake, created from a dry protein powder usually mixed with water or milk and then drunk. There are many different types of protein powder available, but generally these are intended to increase an individual's protein uptake directly following exercise, or through their recovery period, while minimising their intake of undesirable secondary elements such as refined sugars and saturated fat. Variations include specialist drinks to maximise energy or blood glucose levels before training, and similar.

One common element to many of these drinks is that they are provided in powder form (usually in bulk), with a user mixing these with fluid as required. Specialist containers known as 'shaker bottles' are available to allow a user to transport either a pre-mixed drink to the required location, or to allow a user to easily mix a drink on-site away from normal kitchen facilities. A user will add powder and fluid to the container (shaker bottle) and then shake the closed container to agitate and mix the contents

It is common for the powders to only partially dissolve, or for a user to experience difficulties getting the entirety of the powder to dissolve in the fluid. Clumps of 'dry' or undissolved powder frequently end up sticking to the bottom and sides of the container, and in particular in the corners between the base and the side wall. This can be irritating to a user. They may not be able to easily break these up and mix/add them to the main bulk of their drink, and therefore miss out on ingesting part of what is usually a carefully-measured

l dose, or they may need to spend time and effort breaking these up with an implement such as a fork in order to get them to mix properly.

A number of previously-published application address this problem or similar:

US2013/008988 describes and shows a grinding device, comprising a body configured as a hollow barrel having an opening, and a first fixing element positioned close to the opening; an inner cap configured to mount to an inner wall of an end close to the opening of the body having a second fixing element corresponding to the first fixing element, and; wherein an aperture is provided on the inner cap, and a first leak-proof seal is configured to surround the aperture; an outer cover having a second leak-proof seal, wherein the second leak-proof seal is made joint with the first leak-proof seal for leak-proofing; and a grinding element positioned inside the body and capable of moving therein freely; wherein an area of any cross section of the grinding element is bigger than the aperture of the inner cap.

JP3179398 describes and shows a container for mixing liquid and solid foodstuffs having a container with a removable lid with a top opening. The inside perimeter wall of the container has spiral grooves formed into it which are V or 'U'-shaped in cross-section. These assist with swirling the liquid in the container and mixing it with the powder.

US4858759 describes and shows a cartridge for dispensing a two-component mass formed by two interconnected containers so that different combinations of the components can be provided along with different mixture ratios. Initially, the containers are separate with partitions located in their interconnecting regions. The partitions can be removed either before or after the containers are connected together. After removal of the partitions, the components of the mass can be mixed. Following the mixing operation, a piston within the cartridge can press out or dispense the mass through an outlet nozzle formed on one of the containers.

In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.

SUMMARY

It is an object of the present invention to provide a shaker bottle which goes some way to overcoming the abovementioned disadvantages or which at least provides the public or industry with a useful choice.

The term "comprising" as used in this specification and indicative independent claims means "consisting at least in part of. When interpreting each statement in this specification and indicative independent claims that includes the term "comprising", features other than that or those prefaced by the term may also be present. Related terms such as "comprise" and "comprises" are to be interpreted in the same manner.

As used herein the term "and/or" means "and" or "or", or both.

As used herein "(s)" following a noun means the plural and/or singular forms of the noun.

Accordingly, in an aspect the present invention may broadly be said to consist in a shaker bottle for mixing and transporting drinks formed from a separate powder and liquid, comprising: a container configured to hold a volume of fluid and powder for mixing, the container having an at least partly open top; a container lid, the open top and container lid configured for connection so that the container lid can releasably connect with the open top to close the open top, and where the base of the container is configured externally to allow the container to stand on a surface unaided, and configured internally so that the inner surface at the base is rounded. The rounded base helps to prevent powders sticking or clumping in the corners of the container between the base and the side wall when liquid is added to powder in the container, and assists with ensuring the powder and the liquid are fully mixed when a user agitates the bottle to mix the powder and liquid.

In an embodiment, the shaker bottle further comprises a coil mixer having a body at least partly formed from a spaced spiral member, configured to locate within the container and movable within the container to assist with mixing the powder and fluid. The coil mixer moves within the container with the powder and fluid moving through the and across the coil or coils of the mixer so that the mixer helps to fully mix the powder and liquid in the container when the container is agitated

In an embodiment, the coil mixer has at least a portion that substantially follows the curved internal surface of the base. The portion that follows the base helps to ensure that any clumps of powder adhering to the inner surface around the base are broken up and mixed with fluid.

In an embodiment, the shaker bottle further comprises a sieve configured to locate across the open top of the container and strain powder poured into the container therethrough. In use a user pours powder into the container through the sieve, which helps to ensure that the powder is prepared in order to receive the fluid and will mix more readily, and as part of this process helps to ensure that any powder clumps are broken up.

In an embodiment, the container lid comprises a screw-top cap. A screw-top cap provided a more secure seal than a friction or pop-top lid.

In an embodiment, the container lid comprises a main portion configured to close the at least partly open top and a spout portion that extends from the lid and which comprises a separate spout lid. This allows the container to have a larger opening that can be used for filling or cleaning the container, or similar, and for a user to keep the larger opening closed but still access the contents via the spout for drinking, pouring etc, which can be more convenient where the contents is accessed while moving, driving, on public transport, while in a public area, etc.

In an embodiment, at least part of the outer side wall further comprises a slip- resisting means. This assists a user with gripping the container, especially if they have sweaty or wet hands.

In an embodiment, the slip resisting means comprises a separate band configured to extend at least partly around the side of the container. This provides a simple, inexpensive and effective way to provide slip resistance. In an embodiment, the container and band further comprise a plurality of mutually engaging tags and apertures. This helps to connect the band to the container and to ensure the band remains in the required position. In an embodiment, the slip-resisting means is formed from a rubber compound. This allows the band to flex and to contract on to the container while providing excellent gripping properties.

In an embodiment, the lid and band are the same colour. This helps to prevent mix-ups between bottles or cross-contamination between flavours.

In an embodiment, the shaker bottle further comprises a spacing breather formed as a detachable ring that attaches in use between the spout and spout lid and which is configured such that when in position the spout lid is spaced above and away from the spout and air can circulate into and out of the container through the spout. This allows a user to wash the bottle and to leave the interior unsealed or open to atmosphere, which allows air to circulate within the container and helps to prevent the bottle becoming musty-smelling between uses.

In an embodiment, the spacing breather comprises a plurality of apertures sized to allow air to circulate but to prevent ingress of insects or similar into the container via the spout. This helps to allow the bottle to air without allowing unwanted contents to inadvertently enter the bottle while it is airing.

In an embodiment, the container has a coloured side wall. This provides a convenient visual indicator for a user who may have several bottle for use over the course of a day, each with differing contents.

In an embodiment, the side wall of the container is at least partly transparent or translucent. This allows a user to easily visually track the contents level.

In an embodiment, the container side wall has a pair of flattened areas on mutually opposed sides of the container configured to receive the fingers of a user holding the container in their hand. This assists a user with gripping the container in their hand.

With respect to the above description then, it is to be realised that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. This invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more said parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which this invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

An embodiment of the shaker bottle of the present invention will now be described with reference to the figures. The shaker bottle is intended primarily for mixing and transporting drinks formed from a separate powder and liquid, such as for example a protein powder, and a fluid such as water or milk.

The shaker bottle 1 is formed from two main parts: a container 2 and a lid 3.

The container 2 has an elongate generally cylindrical body with an open top. The container has a base 4. Internally, the inner surface of the base 4 is rounded or curved so that in cross-section it appears U-shaped, with a profile similar to that of the base of a test tube. The rounded base helps to prevent powders sticking or clumping in the corners of the container between the base and the side wall when liquid is added to powder in the container, and assists with ensuring the powder and the liquid are fully mixed when a user agitates the bottle to mix the powder and liquid. The container base 4 is configured externally to allow the container to stand on a surface unaided, the side wall at the base 4 diverging to form the curved inner portion and also having a continuation portion 5 that forms a continuation of the main, straight, wall portion above, and which is formed so that the lower part or edge of the continuation portion 5 is incident on a plane. This plane can be the horizontal surface of a table or workbench or similar in use so that the lower edge of the continuation part 5 will rest on the table and support the container, with the main axis of the container 2 extending upwards substantially vertically. The rounded portion and the continuation portion 5 are connected by a series of buttress fins 6 that extend radially therebetween.

The container in this embodiment has a coloured side wall and is translucent. The colour provides a convenient visual indicator for a user who may use several bottles over the course of a day, each with differing contents - for example a pre-workout drink, a post-workout drink, a meal replacement drink, etc. The translucent wall allows a user to easily visually track the contents level.

The container side wall is generally circular in plan view but has a pair of flattened areas on mutually opposed sides of the container 2, which in use allow a user to more easily grip the container in their hand. The container lid 3 and the open top of the container 2 connect via a screw fit. A screw-top lid provides a more secure seal than a friction or pop-top lid, and helps to prevent leaking when the shaker bottle 1 is being transported - for example in a gym bag or similar. The container lid 3 has a spout 7 that extends upwards from the main portion of the container lid 3, towards one side of the container lid 3. The spout 7 has a separate spout lid 8. The spout allows a user to drink or pour the contents of the container 2 through a smaller more convenient opening that lessens the chances of spillage around the sides of the container and/or the corners of the user's mouth. This can be more convenient where the contents is accessed while moving, driving, on public transport, while in a public area, etc, where a user may be moving, or may be knocked or pushed, and where an open container makes spillage more likely. The container lid 3 can be removed when a larger aperture is required, for example for filling or cleaning when a larger opening makes accessing the interior of the container easier.

The shaker bottle is provided with a removable spacing breather 1 formed as a detachable ring that attaches in use between the edge of the spout 7 and the edge of the spout lid 8. The body of the breather 11 is configured such that when in position the spout lid 8 is spaced above and away from the spout 7 by the breather 11. A plurality of apertures are formed into the side wall of the breather 11 , sized to allow air to circulate into the container 2 via the spout 7, but to prevent ingress of insects or similar into the container 2. This helps to allow the bottle to air without a user having to clean or dispose of unwanted contents such as insect bodies. This allows a user to wash the bottle and to leave the interior unsealed or open to atmosphere, which allows air to circulate within the container and helps to prevent the bottle becoming musty-smelling between uses.

The shaker bottle 1 is provided with a sieve 13 that can be removably emplaced to extend across the open top of the container so that the whole of the open top is covered by the sieve when the lid 2 is removed. The sieve helps mix the powder together when the powder and liquid are combined, and helps to break up any additional lumps.

A coil mixer 9 is provided as part of the shaker bottle 1. The coil mixer 9 has a body at least partly formed from a spaced spiral member, in this case from a wire spiralled so that it has a generally spherical outer form. The coil mixer is placed in the container 2 in use, and is sized and shaped so that it conforms with and follows the rounded internal surface of the base portion 4. The coil mixer 9 moves within the container 2 in use, for example when a user shakes or otherwise agitates the shaker bottle 1 with powder and fluid present to mix the powder and fluid, these moving through and across the coil or coils of the mixer so that the mixer helps them to fully mix The portion of the coil mixer that follows the base 4 helps to ensure that any clumps of powder adhering to the inner surface around the base are broken up and mixed with fluid - the coil breaks down any clumping around the base, on the walls or within the main body of the fluid in the bottle 1.

The outer surface of the container 2 is fitted with a slip-resistant band 10 that extends around the container 2. This assists a user with gripping the container 2, especially if they have sweaty or wet hands. A number of tags 12 are formed to extend from the side wall of the container 2. In use these pass through apertures in the band to engage with the band 10. This helps to ensure the band 10 remains in the required position, and will not slip away from it's position. The band 10 is formed from silicone rubber or similar.

The shaker bottle can be fitted with multiple bands in parallel at different heights on the bottle, these can be used for different information, for example a main or global brand in the centre and local contact information or similar on an upper or lower band above or below this.

The advantages of the shaker bottle as described above include but are not limited to: · The bottle is easy to clean and dishwasher friendly.

• There is no need for additional containers or secret compartments.

• The different colours of bottles allow different bottles to be easily

identifiable, this helps to prevent different flavours from becoming mixed up (for example, chocolate flavoured workout, orange flavoured recovery, etc. Mixing taints both bottle flavours. By using colours it helps a user to keep flavours clean or swap sections with friends or partners. The lid, bands, cap and spacer for a single unit can all be one colour, to help prevent mix-ups between bottles or cross- contamination between flavours.

Information such as "pre workout", "workout" "post workout/recovery" or meal replacement can be labelled on the band 10.

The bands around the bottle can be customised for different brands. For example, the central band can be screen printed with the company's logo/brand.
