OPENING/CLOSING PART OF BAG WITH THIN ADHESIVE MAGNETIC FILM CHARACTERIZED BY ITS PERMANENT MAGNET PROPERTY THEREON ENABLING ONE-HAND OPENING AND CLOSING WITH ITS MAGNETIC FORCE

摘要

PROBLEM TO BE SOLVED: To solve the problem that a conventional zipper bag of synthetic resin with an openable and closable mouth having a storage zipper or a male-female engagement keeps the opening and closing part hard to be structured to need both hands and causes inconvenience for those who can use only one hand and also causes inconvenience due to its bulkiness when hand-carried.;SOLUTION: A magnetic film of ferrite compound powder mixed with high polymer material powder is processed into a thin tape and is given adhesion before pasted onto a bag body. The thin tape magnetic film provided on the opening and closing part of the bag enables the bag to open and close using its magnetic property. To open the bag, the opening and closing part thereof is misaligned by one hand so that the positions of the facing magnets change and poles thereof become the same and cause repelling therebetween. When the positions come back to the original, attraction of the magnets of different polarity enables closing. The bag is openable and closable by one hand, secure, compact and conveniently portable, so is usable as a storage bag for daily medicine.;COPYRIGHT: (C)2012,JPO&INPIT
