Adhesive packaging system

Abstract

A two part adhesive packaging system is provided. The packaging system includes two containers for holding a two-part adhesive. The packaging system further includes a connector having two ports for communicating with the containers. A membrane is adhered overtop the ports to prevent the two-part adhesive from draining from the containers. The membrane is configured to break upon application of a sufficient force thereon, such as by pumping or pushing the two-part adhesive from the containers.

The following is claimed: 
     
         1 . A package system comprising:
 a first container that defines a first space;   a second container that defines a second space, the second container connected to the first container;   a connector connected to an outer surface of the first container and an outer surface of the second container, wherein the connector has an outer surface, a side surface, and a connection feature disposed on the side surface;   a first port disposed in the outer surface of the connector and in communication with the first space;   a second port disposed in the outer surface of the connector and in communication with the second space; and   a membrane adhered to the outer surface of the connector, wherein the membrane covers the first port and the second port.   
     
     
         2 . The package system of  claim 1  further comprising a cap removably attached to the connector by the connection feature, wherein the cap contacts the membrane. 
     
     
         3 . The package system of  claim 1  further comprising a mixing nozzle removably attached to the connector by the connection feature, wherein the mixing nozzle is disposed overtop the membrane. 
     
     
         4 . The package system of  claim 3  wherein the connection feature includes threads. 
     
     
         5 . The package system of  claim 4  wherein the connector is fixedly connected to the first and second containers. 
     
     
         6 . The package system of  claim 5  further comprising a polyol disposed within the first space and an isocyanate disposed within the second space, and wherein the polyol and the isocyanate are mixed by the mixing nozzle to form a urethane adhesive. 
     
     
         7 . The package system of  claim 6  further comprising a first piston disposed in the first space and a second piston disposed in the second space, and wherein the pistons move to push the polyol and the isocyanate out through the ports to break the membrane and enter the mixing nozzle. 
     
     
         8 . The package system of  claim 7  wherein the first piston is in contact with the polyol and the second piston is in contact with the isocyanate. 
     
     
         9 . The package system of  claim 1  wherein the outer surface of the connector is planar. 
     
     
         10 . The package system of  claim 1  wherein the connector includes a peripheral flange disposed along an outer circumference of the connector and a linear flange disposed on the outer surface between the first port and the second port, and wherein the membrane is adhered to the peripheral flange and the linear flange. 
     
     
         11 . A package system comprising:
 a first container that defines a first space;   a second container that defines a second space, the second container connected to the first container;   a connector connected to a outer surface of the first container and an outer surface of the second container, wherein the connector has a planar outer surface, a side surface, and a connection feature disposed on the side surface;   a first port disposed in the planar outer surface of the connector and in communication with the first space;   a second port disposed in the planar outer surface of the connector and in communication with the second space; and   a membrane adhered to the outer surface of the connector, wherein the membrane covers the first port and the second port.   
     
     
         12 . The package system of  claim 11  further comprising a cap removably attached to the connector by the connection feature, wherein the cap contacts the membrane. 
     
     
         13 . The package system of  claim 11  further comprising a mixing nozzle removably attached to the connector by the connection feature, wherein the mixing nozzle is disposed overtop the membrane. 
     
     
         14 . The package system of  claim 13  wherein the connection feature includes threads. 
     
     
         15 . The package system of  claim 14  wherein the connector is fixedly connected to the first and second containers. 
     
     
         16 . The package system of  claim 15  further comprising a polyol disposed within the first space and an isocyanate disposed within the second space, and wherein the polyol and the isocyanate are mixed by the mixing nozzle to form a urethane adhesive. 
     
     
         17 . The package system of  claim 16  further comprising a first piston disposed in the first space and a second piston disposed in the second space, and wherein the pistons move to push the polyol and the isocyanate out through the ports to break the membrane and enter the mixing nozzle. 
     
     
         18 . The package system of  claim 17  wherein the first piston is in contact with the polyol and the second piston is in contact with the isocyanate. 
     
     
         19 . A package system comprising:
 a first container that defines a first space;   a second container that defines a second space, the second container connected to the first container;   a connector connected to an outer surface of the first container and an outer surface of the second container, wherein the connector has an outer surface, a peripheral flange disposed along an outer circumference of the outer surface of the connector and a linear flange disposed radially on the outer surface of the connector;   a first port disposed in the outer surface of the connector and in communication with the first space;   a second port disposed in the outer surface of the connector and in communication with the second space, wherein the second port is located on an opposite side of the linear flange than the first port; and   a membrane adhered to the peripheral flange and the linear flange of the connector, wherein the membrane covers the first port and the second port.   
     
     
         20 . The package system of  claim 19  further comprising a mixing nozzle removably attached to the connector by the connection feature, wherein the mixing nozzle is disposed overtop the membrane.
