Dispensing apparatus for pre-cut wiping materials with loading of pack of material

Abstract

A machine for dispensing pre-cut wipe materials comprises a parallelepiped-shaped housing with a back plate and a cover. A base of the cover is articulated on a connecting pin. A support-container holds a stack of pre-cut material which is in use and can hold a spare stack. A base of the support-container is articulated around the same axis of rotation and the cover internally has a horizontal plate which supports the stack in use after swivelling the cover and support-container to load the spare stack. The support-container fits inside and is dismountably attached to the housing after swivelling into the internal space of the housing, which causes downward displacement of the stack in use, allowing the spare stack to be inserted into the internal space. The stack in use and the spare stack are joined to each other after positioning the spare stack on the other stack.

1 . A machine for dispensing pre-cut wipe materials, comprising a parallelepiped-shaped housing with a back plate and a cover, a base of the cover being articulated on a connecting pin around an axis of rotation and including means of locking, a support-container which holds a stack of pre-cut material which is in use and has capacity to hold a spare stack of material, a base of said support-container being articulated relative to the cover and the housing around the axis of rotation, and the cover internally has, in an upper part, a horizontal plate which constitutes a support base for the stack of material which is in use after swivelling the cover and the support-container to load the spare stack of material, and said support-container is fits inside and is dismountably attached to the housing after swivelling into internal space of the housing, and swivelling of the support-container causes downward displacement of the stack of material which is in use, thereby allowing the spare stack of material to be inserted into the internal space of said support-container, and means for joining the stack of material which is in use and the spare stack of material to each other after positioning the spare stack of material on the stack of material which is in use. 
     
     
         2 . A machine as claimed in  claim 1 , wherein the support-container comprises a front wall which is parallel to the back plate of the housing when the machine is closed, two side walls which fit inside the housing, a bottom base and, above the bottom base, the horizontal plate to support the stack of wipe material during operation. 
     
     
         3 . A machine as claimed in  claim 2 , wherein re-entrant side walls of the support-container are provided with protruding pins for locking in position in openings in side walls of the housing. 
     
     
         4 . A machine as claimed in  claim 2 , wherein an upper part of the support-container has a connecting band located opposite wall facing the back plate of the housing, said band having a cut-out to allow movement of the means of locking and a fixed vertical tab involved in said locking. 
     
     
         5 . A machine as claimed in  claim 1 , wherein an inner face of the cover has a protruding shape which allows pre-cutting and prevents creasing of the material, and an outer face of the front wall of the support-container is provided with a curved shape which fits into a space defined by and concentric with the protruding shape and leaves room for the strip of material to pass through. 
     
     
         6 . A machine as claimed in  claim 5 , wherein the protruding shape surrounds a central cut-out and the curved shape surrounds a cut-out, said cut-outs allowing the strip of material to emerge. 
     
     
         7 . A machine as claimed in  claim 6 , with a lower part comprising, around the cut-outs, opposite-facing positionally adjustable limit stops, said limits stops having a stub to guide pulled material out of the machine and makes it easier to separate a piece of strip starting from ane adjacent perforation line. 
     
     
         8 . A machine as claimed in  claim 1 , wherein, when the spare stack of material is loaded, said spare stack is attached by its exposed fold facing an exposed fold of the stack of material which is in use by at least one partly detachable joining means in order to allow adhesive bonding of the two stacks by their opposite-facing folds. 
     
     
         9 . A machine as claimed in  claim 8 , wherein the joining means comprises double-sided tape with an adhesive-coated part in the form of a pad attached to the opposite-facing face of the exposed fold of the spare stack of material and a protruding, detachable tab of the receiving stack which can be grasped by an operator. 
     
     
         10 . A machine as claimed in  claim 9 , wherein the tab has a part which is attached to the pad and a part which protrudes from the stack that can be grasped, thus allowing removal of said tab by pulling and secure bonding of the opposite-facing folds of the stacks of material 
     
     
         11 . A machine as claimed in  claim 5 , comprising several alternating shapes to allow better control of tension of thick material, said shapes being concentric and nested in each other. 
     
     
         12 . A machine as claimed in  claim 9 , wherein the tab has a bent middle part located opposite its end which protrudes from the stack to be grasped by the operator 
     
     
         13 . A machine as claimed in  claim 9 , wherein a ratio of the length of the tab to the length of the adhesive-coated part is in the range of 1.5 to 2.5.
