Embodiment Construction

[0042]Referring to the drawings, the invention provides a drinking straw 1 for progressively adding an active ingredient to a carrier liquid as the liquid is drawn through the straw. It will be appreciated that FIGS. 1, 2A and 2B show the straw as being of indefinite length.

[0043]Typically, the carrier liquid is a plain beverage such as milk or water, and the active ingredient is a flavouring and / or colouring agent. It should be appreciated, however, that other active ingredients, such as pharmaceuticals, vitamin and mineral supplements, antioxidants, herbal remedies or probiotics, and other carrier liquids, may additionally or alternatively be used.

[0044]As can be seen in FIG. 1, the straw 1 includes a generally elongate tubular body 2 having an internal bore 3 and a sidewall 4, adapted for use as a straw. The tube 2 includes first and second filters 5 and 6 disposed at respective first and second ends 7 and 8, of the tube. Together, the first and second filters retain a predetermi...

Abstract

A drinking straw (1) for progressively adding an active ingredient to a carrier liquid as the liquid is drawn through the straw. The straw (1) includes a generally elongate tubular body (2) having an internal bore (3) and a sidewall (4). The tube (2) includes first and second filters (5) and (6) disposed at respective first and second ends (7) and (8), of the tube. Together, the first and second filters retain a predetermined measure of soluble active ingredients within the bore of the tube (2), while allowing a carrier liquid to be drawn through the straw, by oral suction. The active ingredient, takes the form of a plurality of solid pellets (9). Each filter is formed by blocking, closing or constricting the tube at or adjacent the corresponding end and providing at least one aperture sized to be sufficiently small to retain the pellets within the tube whilst sufficiently large to allow passage of liquid.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to a method and apparatus for the addition of soluble agents or ingredients to a carrier liquid, at the point of consumption, for oral administration through a straw.[0002]The invention has been developed primarily for use in relation to the flavouring of pre-packaged or bottled beverages such as milk, and will be described with reference to this application. It will be appreciated, however, that the invention is not limited to this particular use and may be also used to provide flavouring or colouring to other beverages, or for the oral administration of soluble nutritional, pharmaceutical, health or energy enhancing agents.BACKGROUND OF THE INVENTION[0003]The following discussion of the prior art is provided as technical background, to enable the features and benefits of the invention to be fully appreciated in an appropriate technical context. However, any reference to the prior art should not be taken as an expr...
