Abstract

A flavoring receptacle contains a predetermined portion of flavoring agent for sale and use in conjunction with a compatible pre-packaged unflavored beverage of appropriate relative volume. The flavoring receptacle is generally elongate and tubular in shape and contains end caps. The flavoring receptacle is thereby adapted for use as a straw. Passage of the unflavored beverage through the flavoring receptacle provides for mixing with the flavoring agent to produce a flavored beverage.

Claims

1. A flavouring receptacle intended to be used as a straw including an elongate tubular body, a predetermined measure of flavouring agent in granular form contained within said elongate tubular body, and a pair of end caps disposed at and in opposite ends of the elongate tubular body, the caps including perforations dimensioned to be sufficiently small to retain the granules within the elongate tubular body and sufficiently large to allow relatively unimpeded passage of liquid therethrough, the end caps being generally conical in shape so as to provide an increase in surface area for the perforations relative to flat end caps of corresponding comparable diameter so as to increase the effective cross-sectional flow area for liquid to pass through, reach end cap further including a cylindrical portion extending longitudinally with respect to the axis of the tubular body and engaging the bore of the tubular body, the receptacle being adapted for use as a drinking straw in conjunction with a compatible unflavoured beverage, whereby the flavouring agent is progressively added to the beverage upon passing over the granules, through the straw.

2. A flavouring receptacle according to claim 1, wherein the tubular body contains a predetermined portion of the flavouring agent adapted for sale and use in conjunction with a compatible pre-packaged unflavoured beverage in a container of appropriate relative volume, thereby permitting a consumer to select and mix the flavouring agent and the unflavoured beverage at a point of sale for immediate consumption.

3. A flavouring receptacle according to claim 1, wherein the intensity of flavouring delivered to the beverage can be controlled by the consumer according to the rate at which the liquid is drawn through, and hence the dwell time within, the straw.

4. A flavouring receptacle according to claim 1, wherein said end caps are retained in the ends of the straw by means selected from the group consisting of an interference fit, peripheral locating ribs, heat shrinkage, thermal plastic welding and ultrasonic welding.

5. A flavouring receptacle according to claim 4, wherein said end caps are retained in the ends of the straw by means of peripheral locating ribs.

6. A flavouring receptacle according to claim 4, wherein said end caps are retained in the ends of the straw by means of heat shrinkage.

7. A flavouring receptacle according to claim 4, wherein said end caps are retained in the ends of the straw by means of thermal plastic welding.

8. A flavouring receptacle according to claim 4, wherein said end caps are retained in the ends of the straw by means of ultrasonic welding.

9. A flavouring receptacle according to claim 4, wherein said retention means is an interference fit.

10. A flavouring receptacle according to claim 1, wherein an internal region of the straw is not filled entirely with flavouring, whereby a residual free space facilitates agitation of the granules and thereby enhances mixing of the flavouring with the plain beverage passing through the straw.

11. A flavouring receptacle according to claim 1, wherein the flavouring agent is selected from the group consisting of chocolate, strawberry, vanilla, malt, banana, caramel, and coffee flavouring, and is adapted for use in conjunction with unflavoured milk.

12. A flavouring receptacle according to claim 1, wherein the flavouring agent includes a vitamin supplement.

13. A flavouring receptacle according to claim 1, wherein the flavouring agent includes a pharmaceutical adapted for oral administration.

14. A flavouring receptacle according to claim 1, wherein the tubular body is formed substantially from a wax coated paper.

15. A flavouring receptacle according to claim 1, wherein the tubular body is formed substantially from a plastics material.

16. A flavouring receptacle according to claim 1, wherein the height of the tubular receptacle is greater than the height of the beverage container, thereby to avoid inadvertent loss of the straw within the container.

17. A flavouring receptacle according to claim 1, being hygienically sealed in an outer wrapper adapted for removal by a consumer immediately prior to use.

18. A flavouring receptacle according to claim 1, the conical portion of at least one of the end caps extends inwardly along a longitudinal axis toward an interior region of the straw.
