Stack of bags including front and rear tabs

Abstract

In a stack of vest-style carrier bags S, each bag comprises a front layer and a rear layer of flexible plastics material joined at the base and sides and defining an open mouth end. Handles extend from the open mouth end. A tab extends from each ply of material between the handles. An attachment block is provided between the handles and the handles are separably attached to the block by perforated lines of weakening. Front and rear tabs are separably attached to the attachment block. The rear tab of one bag is also separably attached to the front tab of the next bag in the stack so as to effect pulling of the front tab of the next bag from the stack. A container C is also provided for the stack with an opening 0 for allowing the bag to be removed and the subsequent front tab to protrude therethrough.

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 handles 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.  
   
   
       2 . A stack of vest-style bags according to  claim 1  in which each bag is made from an elongate tube, sealed along the base and cut to define handles, a mouth and the tabs.  
   
   
       3 . A stack of vest-style bags according to  claim 1  in which each bag comprises two plys of material, sealed along the base and the side edges and cut to define the handles, a mouth and the tabs.  
   
   
       4 . A stack of vest-style bags according to  claim 1  in which the attachment between the rear and subsequent front tabs is effected by means of an adhesive.  
   
   
       5 . A stack of vest-style bags according to  claim 1  in which the tabs can be locally deformed so that the material of the rear tab is pushed into a depression formed in the front tab of the next bag.  
   
   
       6 . A stack of vest-style bags according to  claim 5  in which one or both of the rear surface of the rear tab and the front surface of the front tab are treated to enhance the adhesion of the tabs together when locally deformed.  
   
   
       7 . A stack of vest-style bags according to  claim 6  in which the treatment is an electrostatic discharge treatment, known as a “Corona” treatment.  
   
   
       8 . A stack of vest-style bags according to  claim 1  in which the front tab of each bag includes a marking or markings indicating that the user should pull the tab to remove the bag from the stack.  
   
   
       9 . A stack of vest-style bags according to  claim 1  in which the front and rear tabs, when tied together, close the mouth of the bag.
