SUBSTANCE APPLICATOR HAVING A CONTROLLABLE SUBSTANCE FLOWRATE

摘要

Various embodiments are directed to an applicator for dispensing a substance according to a desired flow rate. The applicator comprises a flexible card, a substance reservoir attached thereto, and an applicator head secured to the flexible card opposite the substance reservoir. The applicator head comprises a plurality of pores that, when secured to the flexible card, are compressed. In various embodiments, the pores are compressed by physical compression and/or by annealing. Upon flexing the flexible card along a score line, the substance reservoir ruptures and the substance is directed into the applicator head. Upon introduction of the substance to the applicator head, the pores of the applicator head expand and the substance is directed to an applicator surface of the applicator head.

主权项

1. An applicator for storing and dispensing a substance, the applicator comprising:
a substance reservoir configured for storing a substance therein, wherein the substance reservoir comprises a flexible support card having at least one closed score line defining at least one axis of rotation and configured to flex about the at least one axis of rotation between a closed configuration and an activated configuration that opens the at least one score line when flexed; and an applicator head comprising a plurality of pores and coupled to a surface of the flexible support card adjacent the at least one score line, wherein the applicator head is configured to flex with the flexible support card between:
the closed configuration in which at least a portion of the pores are compressed; andthe activated configuration in which at least a portion of the pores become less compressed when the flexible support card is flexed about the axis of rotation.
