Adhesive dispenser system
View Patent ↗A dispenser system employs a packaging module for use with moisture sensitive materials. The packaging module comprises an outer carton and an inner bladder, which is substantially impermeable to moisture and is filled with one part of an adhesive. The carton is loaded on a mobile cart and the one part adhesive is supplied to a pump/mixer without exposure to moisture in the atmosphere. The packaging and dispensing system can be used in conjunction with mechanized adhesive application equipment for the construction trades.
1. A dispensing system for a two-part adhesive comprising:
a cart having a tray defining first and second tray apertures and mounting a pump assembly having a pair of inlets and a pair of outlets, each outlet communicating with a hose communicating with a common dispenser;
a first package enclosing an inner enclosure containing a first adhesive component of said two-part adhesive;
a second package enclosing an inner enclosure containing a second adhesive component of said two-part adhesive;
a first cap with a fitting mounted to said first enclosure;
a second cap with a fitting mounted to said second enclosure;
said first and second enclosures each being disposed above and supported by said tray so that said first and second fittings extend through said first and second apertures, respectively;
a first conduit communicating via a first valved connector assembly between the first enclosure and one said inlet; and
a second conduit communicating via a second valved connector assembly between the second enclosure and a second said inlet, wherein said first and second adhesive components are pumped by said pump assembly and traverse through said first and second tray apertures to said hoses, are mixed and are dispensed as two-part adhesive through said dispenser.
2. The dispensing system of claim 1 wherein each said package has a rectilinear corrugated configuration.
3. The dispensing system of claim 1 wherein said tray includes a retention flange surrounding said enclosures and said first enclosure and said second enclosure are disposed in generally aligned adjacent side disposition on said tray.
4. The dispensing system of claim 1 wherein at least one connector assembly does not permit exposure of the component in the enclosure to the atmosphere upon connection of the conduit.
5. The dispensing system of claim 4 wherein said connector assembly comprises a poppet valve and a snap fit type connection.
6. The dispensing system of claim 1 wherein at least one conduit has a snap-fit type engagement connector assembly which closes off the corresponding opening upon disconnecting said associated conduit from an associated opening.
7. The dispensing system of claim 1 wherein each said hose is transparent.
8. The dispensing system of claim 1 wherein each said enclosure includes a spout adjacent to a said opening.
9. A dispensing system for a two-part adhesive comprising:
a cart having a tray defining first and second tray apertures and mounting a pump assembly having a pair of inlets and a pair of outlets, each outlet communicating with a hose communicating with a common dispenser;
a first package enclosing an inner enclosure defining a first opening and containing a first adhesive component of said two-part adhesive;
a second package enclosing an inner enclosure defining a second opening and containing a second adhesive component of said two-part adhesive;
a first cap having a valved fitting and mounted to said first enclosure at said first opening;
a second cap having a valved fitting and mounted to said second enclosure at said second opening;
said first and second enclosures each being disposed above and supported by said tray and said first and second caps being received in said first and second apertures, respectively;
a first conduit communicating via a first valved connector assembly between the first opening and one said inlet; and
a second conduit communicating via a second valved connector assembly between the second opening and a second said inlet, wherein said first and second adhesive components are pumped by said pump assembly and traverse through said first and second tray apertures to said hoses, are mixed and are dispensed as two-part adhesive through said dispenser.
10. The dispensing system of claim 9 wherein at least one said package has a rectilinear corrugated configuration.
11. The dispensing system of claim 9 wherein said tray includes a retention flange surrounding said enclosures and said first enclosure and said second enclosure are disposed in generally aligned adjacent disposition.
12. The dispensing system of claim 11 wherein at least one connector assembly does not permit exposure of the component in the enclosure to the atmosphere upon connection of the conduit.
13. The dispensing system of claim 12 wherein said connector assembly comprises a poppet valve and a snap fit type connection.
14. The dispensing system of claim 9 wherein at least one conduit has a snap-fit type engagement connector assembly which closes off the corresponding opening upon disconnecting said associated conduit from an associated opening.
15. A dispensing system for a two-part adhesive comprising:
a first package enclosing an inner enclosure with a first opening and containing a first adhesive component of said two-part adhesive;
a second package enclosing an inner enclosure with a second opening and containing a second adhesive component of said two-part adhesive, said first package and second package being substantially identical;
a first cap having a first valved fitting and mounted to said first enclosure at said first opening;
a second cap having a second valved fitting and mounted to said second enclosure at said second opening;
a cart having a tray defining first and second tray apertures and mounting a pump assembly having a pair of inlets and a pair of outlets, each outlet communicating with a hose communicating with a common dispenser;
said first and second enclosures each being disposed above and supported by said tray wherein said first and second caps are received in said first and second apertures, respectively, and each said valved fitting extends beyond said tray;
a first conduit connecting said first fitting and communicating via a first valved connector assembly between the first opening and one said inlet; and
a second conduit connecting said second fitting and communicating via a second valved connector assembly between the second opening and a second said inlet, wherein said first and second adhesive components are pumped by said pump assembly and traverse through said first and second tray apertures to said hoses, are mixed and are dispensed as two-part adhesive through said dispenser.
16. The dispensing system of claim 15 wherein each said package has a rectilinear corrugated configuration.
17. The dispensing system in claim 15 wherein said tray includes a retention flange surrounding said enclosures and said first enclosure and said second enclosure are disposed in generally aligned adjacent side disposition.
18. The dispensing system of claim 15 wherein at least one connector assembly does not permit exposure of the component in the enclosure to the atmosphere upon connection of the conduit.
19. The dispensing system of claim 18 wherein said connector assembly comprises a poppet valve and a snap fit type connection.
20. The dispensing system of claim 15 wherein at least one conduit has a snap-fit type engagement connector assembly which closes off the corresponding opening upon disconnecting said associated conduit from an associated opening.
