Mobile foam dispenser

Abstract

A foam dispenser assembly may include a base portion, a flexible-walled vessels for A and B components that may include walls that define a volume and an opening, an insert within the volume to separate the walls and maintain the opening unobstructed when the volume is under a negative pressure, and a dry disconnect coupling connected to the opening. A head portion that may be connected to the base portion and associated with the flexible-walled vessels may include a tank and a nozzle assembly that mixes the A and B components and dispenses a foam product generated thereby. The tank is preferably disposed adjacent to the nozzle assembly and in communication with one of the flexible-walled vessels and the nozzle assembly. The tank may include a warming assembly.

1 . A foam dispenser assembly comprising:
 a base portion including a support, a flexible-walled vessel for each of an A component and a B component disposed on the support, and contents disposed in the respective flexible-walled vessels including the A component and the B component, at least one flexible-walled vessel including walls connected about a perimeter to define a volume and an opening, an insert disposed within the volume to separate the walls and maintain the opening unobstructed when the volume is under a negative pressure, and a dry disconnect coupling connected to the walls about the opening;   a head portion connected to the base portion and associated with each of the flexible-walled vessels, the head portion including a tank and a nozzle assembly that mixes the A component and the B component and dispenses a foam product generated thereby; and   the tank disposed immediately adjacent to the nozzle assembly and in fluidic communication with one of the flexible-walled vessels and the nozzle assembly, the tank including a warming assembly that defines a base of an interior volume of the tank.   
     
     
         2 . The foam dispenser of  claim 1 , wherein the insert has thickness of approximately 0.010 inches to approximately 0.030 inches. 
     
     
         3 . The foam dispenser of  claim 1 , wherein the insert includes a plurality of enlarged portions connected by links. 
     
     
         4 . The foam dispenser of  claim 1 , wherein the insert includes an enlarged portion disposed adjacent the opening. 
     
     
         5 . The foam dispenser of  claim 1 , wherein the insert includes a main link having an enlarged portion disposed at each distal end of the main link, a first arm link connected to and extending from the main link having an enlarged portion disposed at a distal end of the first arm link, and a second arm link connected to and extending from each main link enlarged portion having an enlarged portion disposed at a distal end of each second arm link. 
     
     
         6 . The foam dispenser of  claim 1 , wherein the insert defines a pathway through the volume when the walls are disposed in contact over nearly all of a plan view surface area of the walls as a result of the negative pressure so that nearly 100% of the contents of the flexible-walled vessel are withdrawn through the dry disconnect coupling. 
     
     
         7 . The foam dispenser of  claim 1 , wherein the warming assembly includes a heat sink having a upper side in direct contact with the contents of one of the flexible-walled containers when disposed in the interior volume and a lower side contiguous with a heat source. 
     
     
         8 . The foam dispenser of  claim 7 , wherein the warming assembly includes a baffle disposed in spaced relation to the heat sink to define a warming volume between the baffle and the heat sink such that a remainder of the interior volume is disposed above the baffle, the baffle facilitates movement of the contents from the interior volume to the warming volume and retention of heat generated by the heat source within the warming volume for quicker temperature adjustment of the contents disposed in the warming volume. 
     
     
         9 . A foam component container comprising:
 a flexible-walled vessel including walls connected about a perimeter to define a volume and an opening, an insert disposed within the volume to separate the walls and maintain the opening unobstructed when the volume is under a negative pressure, a dry disconnect coupling connected to the walls about the opening and one of an A component and a B component.   
     
     
         10 . The foam component container of  claim 9 , wherein the insert has thickness of approximately 0.010 inches to approximately 0.030 inches. 
     
     
         11 . The foam component container of  claim 9 , wherein the insert includes a plurality of enlarged portions connected by links. 
     
     
         12 . The foam component container of  claim 9 , wherein the insert includes an enlarged portion disposed adjacent the opening. 
     
     
         13 . The foam component container of  claim 9 , wherein the insert includes a main link having an enlarged portion disposed at each distal end of the main link, a first arm link connected to and extending from the main link having an enlarged portion disposed at a distal end of the first arm link, and a second arm link connected to and extending from each main link enlarged portion having an enlarged portion disposed at a distal end of each second arm link. 
     
     
         14 . The foam component container of  claim 9 , wherein the insert defines a pathway through the volume when the walls are disposed in contact over nearly all of a plan view surface area of the walls as a result of the negative pressure so that nearly 100% of the contents of the flexible-walled vessel are withdrawn through the dry disconnect coupling.
