Pastry Bag Having Discharge Valve

Abstract

A pastry bag package comprises a dispensing tip assembly including a self-sealing dispensing valve having resiliently deflectable valve flaps that open when pressure is applied to allow product to pass through a valve orifice and close when pressure is removed to cleanly cut off a dispensed ribbon of topping, icing, or other fluid product. One or more of the valve flaps may be provided with a respective protrusion on a front side of the valve flap facing the direction of applied pressure, wherein the protrusion extends into the flow path of fluid product passing through the valve orifice to form a decorative longitudinal ridge along a dispensed ribbon of product.

1 . A dispensing package for fluid products comprising:
 a bag for receiving fluid product, the bag having a wide end and a narrow end; and   a dispensing tip assembly extending through the narrow end of the bag, the dispensing tip assembly including a dispensing tip having a discharge passage through which fluid product is discharged from the bag, and a dispensing valve arranged to control flow of fluid product through the discharge passage, the dispensing valve including a plurality of valve flaps and a valve orifice covered by the plurality of valve flaps when the dispensing valve is closed, the plurality of valve flaps deflecting in response to a predetermined discharge pressure to open the dispensing valve to permit fluid product to pass through the valve orifice, and the plurality of valve flaps returning to cover the valve orifice upon removal of the predetermined discharge pressure.   
   
   
       2 . The dispensing package according to  claim 1 , wherein at least one of the plurality of valve flaps includes a protrusion on a side thereof facing the wide end of the bag, and the protrusion extends into a flow path of fluid product passing through the valve orifice when the dispensing valve is opened. 
   
   
       3 . The dispensing package according to  claim 2 , wherein each of the plurality of flaps includes a respective protrusion on a side thereof facing the wide end of the bag, and the protrusions extend into the flow path of fluid product passing through the valve orifice when the dispensing valve is opened. 
   
   
       4 . The dispensing package according to  claim 1 , wherein the dispensing valve is removably secured in the dispensing tip. 
   
   
       5 . The dispensing package according to  claim 4 , wherein the dispensing tip assembly further includes a retainer ring for removably securing the dispensing valve in the dispensing tip. 
   
   
       6 . A dispensing valve for controlling flow of fluid product through a passage, the dispensing valve comprising:
 a valve head having a valve orifice therethrough; and   a plurality of valve flaps covering the valve orifice when the dispensing valve is closed, the plurality of valve flaps deflecting in response to a predetermined positive pressure applied to a front side of the valve flaps to open the dispensing valve and permit fluid product to pass through the valve orifice, and the plurality of valve flaps returning to cover the valve orifice upon removal of the predetermined positive pressure;   wherein at least one of the plurality of valve flaps includes a protrusion on the front side thereof, and the protrusion extends into a flow path of fluid product passing through the valve orifice when the dispensing valve is opened.   
   
   
       7 . The dispensing valve according to  claim 6 , wherein each of the plurality of flaps includes a respective protrusion on a front side thereof, and the protrusions extend into the flow path of fluid product passing through the valve orifice when the dispensing valve is opened. 
   
   
       8 . In a dispensing valve having a plurality of resiliently deflectable valve flaps that deflect under applied pressure to open a valve orifice of the valve, the improvement comprising:
 at least one of the plurality of valve flaps including a protrusion on a side of the valve flap against which pressure is applied.
