Sealable collar vacuum cleaner bag |
摘要 |
Air leakage passageways formed by an elongated sealing finger deflected through a sealable collar of a vacuum cleaner bag are substantially eliminated by the use of straddling tabs or an additonal elastic membrane across the collar opening which assure a total seal between the collar opening and the vacuum cleaner inlet fitting when the latter extends through the opening.
