Abstract

Abstract A dispensing device for a soluble granular material is disclosed, which device comprises a tube formed of a liquid-impermeable material and of unitary construction, the tube being closed at both ends and having perforations along a portion of its length at or close to one end, and containing a soluble granular material. Preferably the lower end of the tube has a flattened, paddle-like portion, and the perforations are arranged linearly along opposite sides of the tube aligned with the edges of this flattened portion.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 213 words
A dispensing device for a soluble granular material comprising: an elongated cylindrical plastic tube of continuous unitary thin walled plastic construction as found in a straw; said tube having a diameter of between 0.3 and 1.5 centimeters and said tube having a length of between 10 and 20 centimeters; said tube having first and second ends, said first end being heat sealed and formed into a flat paddle, having a transverse extent greater than the diameter and a thickness of substantially twice the wall thickness of said tube and constituting means for stirring a liquid, and said second end being sealed; particulate material within said tube adjacent said first end thereof; said tube having perforations through the side wall thereof in two zones only, the first directly adjacent said first end and the second at diametrically opposite sides of the tube extending longitudinally on the tube and aligned in a plane defined by the paddle to permit fluid engagement with said particulate material when immersed in fluid and prevent leakage of residual fluid from the tube when laid on a horizontal surface after use; whereby said dispenser may be immersed in a cup of hot liquid and said particulate material dispensed into said hot liquid, with said paddle serving to stir said liquid.
