INFUSION PACKAGES AND METHODS FOR THEIR MANUFACTURE

摘要

An infusion package has two pairs of drawstrings (4) which extend in opposite senses from respective anchoring points (5) in tabs (14) across the infusion containing compartment to generally opposed locations on the peripheral margin of the package where the drawstrings slidably engage and extend from the package. The free ends of the drawstrings are attached to tags (7, 8). In use, after infusion the tags are pulled in opposite directions away from the package. This causes the opposing side edges of the package to move towards each other, thereby compressing the package and expressing residual liquid therefrom. Methods and apparatus for manufacturing the infusion packages are also described.
