Infusion bag squeezing assembly

Abstract

A filter bag has at least one thread forming a pair of spaced apart first and second loops extending between a bottom and top region of the filter bag. The filter bag further has a support traversed by the thread, which forms a loop above the support. The loop is sized so a user can pull the thread and the bag upward toward the support to a squeezing position of the filter bag, wherein the bottom region thereof is lifted toward the top region.

What is claimed is:  
     
         1 . A squeezing device comprising: 
 a bag containing infusible product and having a bottom and top region;    a support having an inner surface facing the top region of the bag; and    at least one filament having a lower stretch looping around the bottom region of the bag and an upper stretch extending through the support, the bag and the support being displaceable relative to one another upon applying a lifting force to the upper stretch of the one filament so as to bring the bag in a squeezing position, wherein the bottom region of the bag is displaced towards the upper region which urges against the inner surface of the support.    
     
     
         2 . The device defined in  claim 1  wherein the one filament has one of opposite ends thereof threaded through the bottom region, so as to form a first loop on the bag upon threading the ends of the thread through the top region, the ends further traversing the support and being sequentially threaded through the top and the bottom region of the bag, thereby forming a second loop on the bag spaced apart from the first loop upon attaching the ends together.  
     
     
         3 . The device defined in  claim 1 , further comprising a lifting element receiving the upper stretch of the one filament and adapted to be held by a user.  
     
     
         4 . The device defined in  claim 3  wherein the lifting element includes two spaced apart flat surfaces bridged by a C-shape intermediate surface.  
     
     
         5 . The device defined in  claim 1  wherein the support has a C cross-section and extends at least along a substantial portion of the top region of the bag.  
     
     
         6 . The device defined in  claim 1  wherein the support has at least one thoroughgoing hole traversed by the upper stretch of the one filament and an outer surface formed with a formation which extends upwardly from the support, the hole including a first region having a diameter at least equal to a width of the filament and a second region having a diameter less than the width, so that displacement of the filament and the support relative each other can be arrested upon displacing the filament into the second region.  
     
     
         7 . The device defined in  claim 1  wherein the inner surface of the support is flat, the support further being formed with a lateral extension adapted to be pressed upon by a user.  
     
     
         8 . The device defined in  claim 1 , further comprising another filament having a lower and upper stretch, the upper stretches of the one and other filaments being connected to one another above the support, and the lower stretches extending peripherally along an exterior of the filter bag under the bottom region and toward the top region to form two spaced apart loops on the bag.  
     
     
         9 . The device defined in  claim 8  wherein the lower stretches of one and other filaments are parallel to one another and form three rectangular regions on the bag.  
     
     
         10 . The device defined in  claim 8  wherein lower stretches are inclined toward one another to form two spaced trapezoidal regions and a triangular region.  
     
     
         11 . The device defined in  claim 1  wherein the support has a pair of resilient flaps formed substantially in a central region of the support and displaceable upward and away from another upon moving the bag towards the squeezing position, the flaps preventing rearward displacement of the bag.  
     
     
         13 . The device defined in  claim 1  wherein the bag has a cross-section selected from the group consisting of pyramidal and annular cross section.  
     
     
         14 . The device defined in  claim 14  wherein the bag having the circular cross-section is formed with a peripheral annular edge receiving the lower stretch of one filament.  
     
     
         15 . The device defined in  claim 1 , further comprising a tag connected to the upper stretch of the filament and having a side covered by an adhesive.  
     
     
         16 . The device defined in  claim 1 , further comprising an outer bag receiving the support and having a pocket which has a shape similar to a shape of the bag.  
     
     
         17 . The device defined in  claim 17  wherein the shape of the pocket is selected from the group consisting of semicircular, pyramidal and polygonal shape.  
     
     
         18 . A squeezing device comprising: 
 a filter bag containing infusible product and having a bottom and top region;    a support having an inner surface facing the top region of the bag; and    a single filament forming a pair of spaced apart loops extending between the bottom and top regions of the filter bag and an upper stretch connecting the loops and extending through the support, the bag and the support being displaceable relative to one another upon applying a lifting force to the upper stretch of the filament, so as to bring the bag in a squeezing position, wherein the bottom region of the bag is displaced towards its upper region which, in turn, urges against the inner surface of the support.    
     
     
         19 . A method of manufacturing a filter bag containing infusible product, the method comprising the steps of: 
 forming a first loop of at least one thread extending between a bottom and top region of the filter bag;    extending ends of the one thread through a support facing the upper region of the filter bag;    forming a second loop of the one thread spaced from the first one on the peripheral wall of the filter bag; and    upwardly displacing an upper stretch of the one thread formed above the support in a squeezing position, wherein the upper region of the bag is in contact with the support so as to enable the first and second loops to vertically squeeze and displace the bottom region toward the upper region.    
     
     
         20 . A squeezing device comprising: 
 a filter bag containing infusible product and having a bottom and top;    a support facing the top of the bag; and    at least one continuous filament extending between the bottom and the support to provide displacement of the bag relative to the support upon applying a lifting force to the filament, so as to bring the bag in a squeezing position, wherein the bottom of the bag is displaced towards its top.    
     
     
         21 . A squeezing device comprising: 
 a filter bag containing infusible product and having a bottom and top; and    at least one continuous filament extending between the bottom and the support to provide displacement of the bag relative to the support upon applying a lifting force to the filament, so as to bring the bag in a squeezing position, wherein the bottom of the bag is displaced towards its top.    
     
     
         22 . The squeezing device defined in  claim 21  wherein the top has a pocket opening towards and receiving the bottom of the filter bag in the squeezing position, said pocket being shaped to arrest upward displacement of the bottom upon applying the lifting force.
