Title: Opening and closing device for bag evacuation opening
Inventor: FUKUNISHI MASAHIRO
IPC: B65D85/07
Filed: 1990-11-22
Abstract: PURPOSE:To reduce the number of parts and permit evacuating operation to be performed rapidly by forming the structure to press a valve body without using any spring. CONSTITUTION:After bedquilt or other contents are received in a bag 17, a closing lid 5 is disengaged from the bag, a suction opening 19 of a vacuum cleaner is connected with a holding part 3 and the vacuum cleaner is operated for the bag evacuation. A valve body 2 is then raised to define an air space between itself and a seating part 1 and air in the bag 17 is sucked out by the vacuum cleaner. At the time of suction, since the air in the bag 17 reaches a ventilation hole 7 through a ventilation window 13 of an underlying cap 4, a smooth air suction can be effected, without the bedquilt or the like received in the bag 17 blocking the ventilation hole 7. Upon disconnection of the suction opening 19 at the end of evacuation, since the inner pressure of the bag 17 is low, the air space produced between the valve body 2 and the seating part 1 placed automatically in contact with each other is closed. When the closing lid 5 is put back in place, the valve body 2 is pressed by the closing lid 5 in the closing direction to keep an evacuation opening closed.
