Claims
- 1. A user closable collar for a vacuum cleaner bag, comprising:a collar body formed from a single blank of relatively rigid material which is folded to define three generally overlapping and planar panels, said collar body further comprising: a partial inner panel which is adhesively secured to a first full outer panel and a second full outer panel; an occlusion element attached to said inner panel by weak retention bands of collar blank material, said occlusion element further containing a detachable pivot therein; and an aperture portion on said first outer panel and an apertured portion on said second outer panel, wherein said partial aperture of the occlusion element is aligned with the apertures of the middle panel and the second outer panel, whereby the occlusion element pivots on said detachable pivot from an open position to a closed position, occluding the apertures on the first and second outer panels.
- 2. The collar of claim 1 further comprising means for severing said weak retention bands and separating said occlusion element from said middle panel and said pivot from said occlusion element.
- 3. The collar of claim 1 further comprising a partial aperture cutout on said occlusion element.
- 4. The collar of claim 1 further comprising a resilient membrane intermediate to said middle panel and one of said first or second outer panels and defining an aperture therethrough aligned with said apertures of said outer panels.
- 5. The collar of claim 1 wherein the detachable pivot point is attached to said occlusion element by weak retention bands and is adhesively secured to said first and second outer panels.
- 6. A user closable collar for a vacuum cleaner bag, comprising:a collar body formed from a single blank of relatively rigid material which is folded to define three generally overlapping and planar panels, said collar body further comprising: a partial inner panel which is adhesively secured to a first full outer panel and a second full outer panel; an occlusion element attached to said inner panel by weak retention bands of collar blank material, said occlusion element further containing a detachable pivot therein and a partial aperture cut-out; an aperture portion on said first outer panel and an apertured portion on said second outer panel, wherein said partial aperture of the occlusion element is aligned with the apertures of the middle panel and the second outer panel; and a resilient membrane intermediate to said middle panel and one of said first or second outer panels and defining an aperture therethrough aligned with said apertures of said outer panels and with the partial aperture cutout of said occlusion element, whereby the occlusion element pivots on said detachable pivot from an open position to a closed position, occluding the apertures on the first and second outer panels.
- 7. A method of making a user closable collar for a vacuum cleaner bag, comprising the steps of:(a) folding a single blank of relatively rigid material to define three overlapping and generally planar panels, said panels defined by a first outer panel, a second outer panel each having apertured therein, and a partial inner panel having a top and bottom portions and occlusion element attached thereto by weak retention bands of collar material and further containing a detachable pivot point therein and a partial aperture cutout; and (b) adhesively securing the top and bottom portions of said middle panel and the detachable pivot point to said first and second outer panels, whereby in a closed position the partial aperture of the occlusion element and the apertures of the outer panels are in alignment and said apertures of the first and second outer panels are occluded when the user breaks the weak retention bands and pivots the occlusion element upon said pivot point to an open position.
- 8. The method of claim 7 further comprising the additional step of interposing a resilient membrane intermediate between one of said outer panels and said middle panel, the resilient membrane defining aperture aligned with the apertures of said outer panels.
