Abstract
The straw designed for the intake of water based drink from a container. In the lower part of the flexible straw there are holes that are connected to the main tube of the straw. Above the holes and attached to the straw, there is a floating device which allows for the intake of the drink from the container only from fixed depth ranges, preferably from 5-15 mm from the surface of the water. The straw allows for the protection of the organism of the user from negative effects of the drink on the body's cells.
Claims22
A drinking straw arrangement floating on a top surface of a drink, comprising:
- a straw having a side wall, said straw extending between a proximal and a closed distal end thereof, at least one intake opening provided within said side wall and spaced from said closed distal end;
- a flotation device having a core portion defined by a top wall and a bottom wall with a hollow space formed therebetween;
- said straw passing through the top, bottom walls and the hollow space, the distal end of the straw extends outwardly from the flotation device, so that the at least one intake opening is located at and submerged into the drink an optimal predetermined distance from the bottom wall of the flotation device, the flotation device supports the straw floating in an upright position on the top surface of the drink.
A drinking straw arrangement for extracting a drink from predetermined depth thereof, comprising:
- a straw having a sidewall defining a central longitudinal passage, said straw extending between a proximal end and a closed distal end thereof, a system consisting of a plurality of intake openings provided within said side wall at said distal end;
- a disc-shaped flotation device having a core portion defined by a top wall and a bottom wall with a hollow space formed therebetween;
- said straw passing through the top, bottom walls and the hollow space, the distal end of the straw extends outwardly from the flotation device, so that the system of intake openings is located at and submerged into the drink an optimal predetermined distance from the bottom wall of the flotation device, the flotation device supports the straw floating in an upright position on the top surface of the drink;
- wherein a combined total area of cross-sections of the intake openings of the system is greater than a cross-section of the central passage of the straw, to allow an intake flow of the drink to be laminar, so as to prevent formation of a turbulent flow bringing the drink from outside of the optimum predetermined depth into the intake openings.
