Description
Device for water supplementation
Field of the Invention
The present invention belongs mainly to the field of sport ancillary equipment, and more particularly of endurance sports equipment, although the invention can find application in such diverse fields such as survival equipment, diving equipment or military ancillary equipment. Mountain bikers and cyclists are also potential users of the invention.
Background to the Invention
There are many situations in which a person has to carry a portable supply of water and drink, such as in endurance sports, survival training, climbing, diving, etc. In other situations, it is not desirable to stop an activity for drinking or is more comfortable or convenient to drink without using the hands, such as in long distance running, mountain biking, etc. In these situations, a hands-free drinking equipment can be used. A hands-free drinking equipment normally comprises a contained water supply, attached for example to the person's body, connected to a mouthpiece by a flexible conduit. The person drinks the water by sucking on the mouthpiece as and when desired. In this way, hands do not need to be used to open the water supply and pour water into the mouth.
It is also well know that during intense and prolonged physical activity, it is necessary not only to keep the body sufficiently hydrated, to compensate the fluids lost by sweating and fast breathing, but also to intake other substances 25 that are also lost or consumed during physical activity, such as electrolytes and/or other nutrients, glucose being an example. To this end there are in the market several sport drinks, gels and other supplements.
While it is desirable to drink sport drinks during intense and prolonged exercise, it is not advisable to drink only sports drinks every time that a sports 5 person requires hydration during prolonged exercise, because this could cause an overconsumption of electrolytes and nutrients that can significantly adversely affect the sports person ability to continue exercising at an intense level. Therefore, if using hands-free drinking equipment, it is not advisable to fill the liquid container with sport drinks and it is preferable to fill it with water. This 10 requires the endurance sports person to carry additional sport drinks besides the water supply, or other nutrient supplies such that he/she must use his/her hands to drink the sports drink or consume the other nutrients, in the form of bars, gels, etc., which can consume time, adversely affect the sporting activity or simply cannot be easily done.
There are additional reasons why it is not advisable to use drinking equipment to carry sport drinks and is that, after use, the liquid container of drinking equipment becomes prone to bacterial growth, due to the sports drinks nutrients residue, if this is not exhaustively washed off.
Summary of the Invention
According to a first aspect of the present invention there is provided a device for providing nutrients to a liquid, the device comprising: a receptacle and a nutrient source wherein the receptacle is, in use, in fluid communication with a container containing a liquid, such that a portion of the liquid can pass into the receptacle, the nutrient source being configured to be selectively introduced to the portion of the liquid in the receptacle.
In at least one embodiment of the present invention such a device is a convenient and fast way to consume nutrients at certain time point while carrying a liquid supply without requiring excessive use of the hands or excessively long interruption of a physical activity. In this way, every time a person requires nutrients, all that is needed is to put the device in fluid communication between his/her mouth and the water supply and suck or pressurise the liquid to flow into the receptacle and drink the nutrient enriched liquid. Other way to mobilise the liquid are also possible, such as tipping the liquid container over the receptacle so that liquid falls under gravity This can be done fast and with minimum requirement of the hands compared to other forms of nutrient consumption, such as opening a bottle or can and drinking from it, or unwrapping a nutrient bar and eating it or opening a gel sachet and consuming it.

The main receptacle 32 comprises an inlet 36 and an outlet 38. The inlet 36 is configured to be snugly connected to a flexible conduit of a hands-free portable drinking equipment (not shown) so that no liquid escapes trough the connection. In this example, the inlet 36 comprises a groove 38 to receive an 0-ring (not shown) and a ridge 40 of larger diameter than the inlet 14 for snugly fit with a flexible conduit.
The removable receptacle 34 is hold in place by a movable tab 42 which can be moved by a finger. The removable receptacle 34 contains the nutrient source (not visible).
Figure 4 shows another embodiment of the present invention, indicated 25 by numeral 50. The device 50 comprises a flexible liquid container, i.e. a bladder 52, a flexible conduit 54 in fluid communication with the bladder 52 and an insert 56 in fluid communication with the flexible conduit 54, such that liquid from the bladder 52 can flow through the flexible conduit 54 and the insert 56. The insert 56 is identical to the device 30 of figure 3 and its working principle is like it has been explained in the description of Figure 2B. The bladder can be carried in a backpack.
This insert 56 however has a by-pass and an internal mechanism that allows the user to select whether to drink water or to drink nutrient enriched liquid without having to disconnect the insert 56 from the bladder 52. This will be described in detail below.
Figures 5A and 5B show a removable receptacle 58 and a main receptacle 32 disengaged from each other, respectively. The removable receptacle 58 comprises a handle 57 to facilitate its manipulation and insertion and remotion from the main receptacle 32.
Figure 6 shows a removable receptacle 60 that contains a nutrient source (not visible) and which can be fitted onto a main receptacle, like the one shown in Figure 5B. The removable receptacle comprises a sliding lid 62 that can be slid into two different positions. One position exposes a permeable membrane (not visible) to the liquid through the apertures 63 in the removable receptacle and allows nutrients contained in the removable receptacle 60 to be entrained by the liquid flowing through the main receptacle. The other sliding lid 62 position effectively covers the apertures 63 of the removable receptacle and prevents nutrients to be introduced in the liquid.
The permeable membrane is a 75 micron food grade nylon mesh. The 25 removable receptacle 60 is made of a biodegradable food-grade plastic such that it is able to contain nutrients and to be disposed in the environment safely after use without damaging the environment, of which plant starch material (PSM) could be an option.
Figure 7A shows a sectional and exploded view of the device 30 shown in Figure 3. Same features are represented by same numerals. In this view it can be seen that the main receptacle 32 comprises four recesses 72 in its interior that are there to receive four helical springs (not shown). The helical springs are there to bias the removable receptacle 34 outwardly from the main receptacle 32. The main receptacle comprises a by-pass piece 74. The by-pass piece 74 provides an alternative flowpath 76 to the liquid in which it does not enters in contact with the nutrient source (not shown), so that a user can drink water only. The alternative flowpath is 1 mm in height.
On top of the by-pass piece 74 there is the removable receptacle 34, which formed by two separable pieces, a container 78 and a lid 80. The container 78 comprises an inlet slot 82 and an outlet slot 84, each of 1 mm of height, that allow fluid to flow through the removable receptacle 34, between the removable receptacle base 86 and a permeable membrane (not shown) located across the whole width and length of the removable container at a height of line 88.
The main receptacle inlet 36 and outlet 38 are 4.75 mm in diameter in the narrowest place, but this can be modified accordingly so as to allow smaller or greater flows of liquid.
The device 30 also comprises a movable tab 42 to hold the removable receptacle 34 in place and prevent that the biasing springs expel the removable 25 receptacle 34 from the main receptacle 36. The movable tab 42 can be retracted so as to facilitate insertion of the removable receptacle 34 into the main receptacle 32.
Figure 7B is a sectional view of the assembled device 30 shown in Figure 7A in exploded view.
In this view can be seen that the main receptacle 36 comprises two guiding recesses 92, 94 that receive two guiding protrusions 96, 98 of the bypass piece 74. These recesses 92, 94 guide the outward and inward movement of the by-pass piece 74 and the removable receptacle 34 so that they do not jam easily.
The removable receptacle 34 also comprises a recess 100 that receives part of the tab 42. The recess 100 is wider than the tab 42 width such that the removable receptacle 34 is not completely fixed when it is assembled in the main receptacle 32. The removable receptacle 34 and the by-pass piece can be moved inward and outward even when the tab 42 is deployed into the recess 100 such that when the removable receptacle 34 and the by-pass piece are displaced to its most outward position (the tab 42 in contact with the lower part of the recess 100), then the water can flow through the alternative flowpath 76 and the user can drink water only (See Figure 8A). It will be appreciated that the springs (not shown) in the recesses 72 bias the removable receptacle 34 into this position.
Selectively, the user can depress the removable receptacle 34 until the tab makes contact with the upper part of the recess 100. In this position, the water can flow through the removable receptacle 34 and entrain nutrients contained in it and the user can easily drink water enriched with nutrients, when he/she choose to do so with a simple finger pressure on the removable receptacle 34 (see Figure 8B).
The present invention provides a device for supplying nutrients in liquid form to a person, which is carrying out a physical activity, sport or cannot use the hands much because he is busy with something else. The device also allows such person to drink liquid, eg. Water, without nutrients. The device comprises a receptacle in which a portion of the liquid supply normally carried with the person is allowed to pass and a nutrient source is introduced in the liquid such that the nutrient enriched liquid can be drunk by the person from the receptacle. In some embodiments, the receptacle contains the nutrient, although in other embodiments the nutrient can be contained in another compartment. Some embodiments comprise a by-pass path such that liquid can flow through or adjacent the nutrient source whilst the nutrient source is entrained or carried by the liquid or the liquid can flow separately from the nutrient source and no nutrients are carried by the liquid. In some embodiments a permeable membrane is used to allow the liquid to come into contact with the nutrient source, entrain or carry it and then flow out of the receptacle.
A diverter mechanism can be incorporated to make the liquid flow towards the nutrient source or separate from it. Some embodiments comprise a 5 compartment to carry the liquid supply.
