Abstract
A dispensing bag for particulate matter is closed at one end by a two layer closure formed by an openable outer closure, and an inner dispersion panel with apertures of suitable size therethrough. Opening the outer closure exposes the apertures in the dispersion panel and permits particulate matter to be dispensed therethrough. The bags may be conveniently mass produced from sheet material, such as flexible plastic, in the form of a continuous strip or flattened tube, by appropriate cutting, folding, and joining operations. The invention provides an inexpensive container from which particulate matter may be conveniently dispensed in controlled fashion, and which resists accidental opening and spillage.
Claims8
A bag for packaging and dispensing particulate matter, comprising:
- flexible front and back sections joined together along the side edges thereof and a flexible double end closure, the double end closure comprising an openable outer closure and a flexible inner gusset having a plurality of apertures therethrough, wherein the outer closure may be opened, to expose the apertures of the inner gusset and to permit dispensing of particulate matter therethrough,
- wherein the front and back sections and double end closure are integral portions of the same section of flexible sheet material, the double end closure being the central portion and the front and back sections being folded over and superimposed end portions having folded end edges,
- wherein the inner gusset of the double end closure comprises an inwardly folded middle portion of the double end closure joined to the insides of the front and back sections along joining lines generally parallel to and approximately equidistant from the folded end edges of the front and back sections, and
- wherein the outer closure comprises portions of the double end closure adjacent the folded end edges of the front and back sections, which are sealed together and also sealed to the front and back sections along a sealing line generally parallel to the folded end edges of the front and back sections and remote from the joining lines of the inner gusset, whereby the outer closure is openable by severing the outer closure along a line between the sealing line and the joining lines of the inner gusset.
A dispensing bag for particulate matter, comprising:
- flexible front and back sections joined together along the side edges thereof;
- and
- a flexible double end closure connecting said front and back sections;
- said double end closure comprising an openable outer closure and an inner closure gusset having a plurality of apertures therethrough, said gusset being contained within the bag when the outer closure is closed;
- wherein said openable outer closure may be opened, thereby exposing said apertures and permitting particulate matter within said bag to be dispensed from said bag through said apertures,
- wherein the inner gusset is joined to the insides of the front and back sections along lines parallel to and remote from the end edges of the front and back sections closest to the double end closure;
- and
- wherein the openable outer closure comprises portions of the double end closure adjacent the end edges of the front and back sections which are sealed together and also to the front and back sections along a line generally parallel to but remote from the lines joining the gusset to the front and back sections.
