【発明の名称】虫駆散薬パッチを収容して提供するためのパッケージ
Document Type and Number:
Japanese Patent JPH10512246
Kind Code:
A
Abstract:
A pouch package, containing a volatile solution-impregnated patch, is made of a peelable barrier film. The pouch envelops an absorbent substrate saturated preferably with bug repellent fluid. A PSA (pressure sensitive adhesive) coated backing film is laminated to the absorbent substrate. The backing film has a connecting portion which is peelably sealed to the inside of the pouch. When the pouch is peeled open, the PSA coated backing film is exposed and placed against a target surface, such as a patch wearer's clothing. Finally, the side of the pouch facing the absorbent substrate is peeled off the backing film connecting portion to expose the absorbent substrate. A key to functionality of the pouch package is differential adhesion. First, the pouch barrier film must be peelable from itself, yet it must not adhere to the pressure sensitive adhesive on the backing film. A release paper may be used to cover the PSA when peeling the pouch open. Second, the pouch film must be peelable from the backing film connecting portion without disturbing the bond between the fastening surface and the target surface. Third, the backing film must be laminated to the absorbent substrate more strongly than the PSA adheres to the backing film, so that when the patch is removed from the target surface, the PSA stays with the patch.
