Stack of bags

Abstract

A stack ( 24 ) of vest-style bags ( 10 ), each bag comprises a front layer and a rear layer of flexible sheet material. The layers define a bag body having a closed base end ( 12 ), closed sides ( 14, 16 ) and an open mouth end ( 18 ) opposite the base end ( 12 ). The front and rear layers each define a tab ( 42 ) extending between handles ( 20, 22 ) of the bag. Each handle part defines an aperture ( 30, 32 ) to receive a pin of a dispenser. A further aperture ( 36 ) is provided to receive a hook pin of the dispenser adjacent the mouth of the bag.

1 . A stack of vest-style bags, each bag comprising a front layer and a rear layer of flexible sheet material, the layers defining a bag body having a closed base end, closed sides and an open mouth end opposite the base end, and two handle parts spaced from each other and extending from the open mouth end, the front layer further defining a front tab extending from the open mouth end from a point between the two handle parts, the rear ply further defining a rear tab extending from the open mouth end from a point between the two handle parts, the rear tab of one bag in the stack being separably attached to the front tab of the subsequent bag in the stack, the handle parts each have an aperture so placed as to receive the pins of a dispensing device, a further aperture is arranged through the walls of the bag adjacent the mouth of the bag to receive a pin or hook form normally associated with a dispensing device or mounting structure.  
   
   
       2 . A stack of bags according to  claim 1  in which the apertures are so formed as to limit the reduction in strength caused by the reduction in width of the handle formation.  
   
   
       3 . A stack of bags according to  claim 1  or  2  in which the handle formation is modified in width and/or form to retain the overall strength as observed without the aperture present.  
   
   
       4 . A stack of bags according to  claim 1 ,  2  or  3  in which the further aperture or apertures may be located equidistant between the handle formations adjacent to the mouth of the bag.  
   
   
       5 . A stack of bags according to any preceding claim in which a non-precipitating slot or cut is provided running from the aperture adjacent to the mouth of the bag.  
   
   
       6 . A stack of vest-style bags, each bag comprising a front layer and a rear layer of flexible sheet material, the layers defining a bag body having a closed base end closed sides and an open mouth end opposite the base end, and two handle parts spaced from each other and extending from the open mouth end, the handle parts each have an aperture so placed as to receive the pins of a dispensing device, a further aperture is arranged through the walls of the bag adjacent the mouth of the bag to receive a pin or hook form normally associated with a dispensing device or mounting structure and a non-precipitating slot formation is provided running from the aperture adjacent the mouth of the bag.  
   
   
       7 . A stack of bags according to  claim 5  or  6  in which the non-precipitating slot is effected by the breaking of a semi-permanent feature created of the body of the bag, between the aperture and a slot.  
   
   
       8 . A stack of bags according to  claim 5 ,  6  or  7  in which a tear non-precipitation formation is provided at an end of the slot spaced from the aperture.  
   
   
       9 . A stack of bags according to any of  claims 1  to  4 , in which the aperture formed adjacent to the mouth of the bag is formed in a position so as to create a thinned area of the wall of the bag so as to provide a means of weakening such an area to become detachable upon manual pulling of the front face of the bag.  
   
   
       10 . A stack of vest-style bags, each bag comprising a front layer and a rear layer of flexible sheet material, the layers defining a bag body having a closed base end, closed sides and an open mouth end opposite the base end, and two handle parts spaced from each other and extending from the open mouth end, the handle parts each have an aperture so placed as to receive the pins of a dispensing device, a further aperture is arranged through the walls of the bag adjacent the mouth of the bag to receive a pin or hook form normally associated with a dispensing device or mounting structure and the aperture adjacent the mouth of the bag is formed in a position to create a thinned area of the wall of the bag so as to provide a means of weakening such an area to become detachable upon manual pulling of the front face of the bag.  
   
   
       11 . A stack of bags according to  claim 9  or  10 , in which the aperture is located off-centre of the bag so as to form a thin wall part and a thick wall part.  
   
   
       12 . A stack of vest-style bags, each bag comprising a front layer and a rear layer of flexible sheet material, the layers defining a bag body having a closed base end, closed sides and an open mouth end opposite the base end and two handle parts spaced from each other and extending from the open mouth end, the front layer further defining a rear tab extending from the open mouth end from a point between the two handle parts, the rear tab of one bag in a stack being separably attached to the front tab of the subsequent bag in the stack, each tab being so formed as to act as an anchor for the placement of the tab on, through or around the hook/pin formation of the supporting dispenser system, or other known dispensing systems, the formation of the tab being formed such as to restrain the tab, through, behind or around the hook/pin of the dispensing system whilst static.
