Claims
- 1. The method for assembling a dispenser with liquid product, said dispenser comprising a cylindrical drum and a distributor pump assembly, said drum having a wall, said wall having an upper part and an internal bearing surface, and said assembly comprising a sealing sleeve, said sealing sleeve housing a pump, said pump having a normally closed intake valve, said method comprising the steps of:
- providing said upper part of said drum wall with an air escape passage (1c);
- filling the drum with liquid product to a predetermined level;
- inserting said assembly into the drum with an outer bearing face (4c) of said assembly slideably engaging said upper part and forcing a first portion of air out of said drum via said escape passage (1c) during said insertion; and
- moving said assembly further into the drum, with said outer bearing face (4c) forming a seal with said internal bearing surface (1b) of said drum wall, and until a lower face (4a) of said assembly contacts a surface of said liquid product; and
- forcing open said intake valve by continuing the moving of said assembly into said drum and moving said lower face (4c) into said liquid product to force a second portion of air and a quantity of liquid product into said pump.
- 2. The method for assembling a dispenser with liquid product, said dispenser comprising a cylindrical drum and a distributor pump assembly, said drum having a wall, said wall having an upper part and an internal bearing surface, said assembly comprising a pump and a sealing sleeve, said pump having a normally closed intake valve, said method comprising the steps of:
- providing said assembly with a flexible skirt (4c);
- filling the drum with liquid product to a predetermined level; and
- inserting said assembly into the drum with said flexible skirt slideably engaging said wall until a lower face (4a) of said assembly comes into contact with a surface of said liquid product and then moves into said liquid product to force air and then a portion of liquid product contained in said drum past said flexible skirt.
- 3. The method for assembling a dispenser with liquid product, said dispenser comprising a cylindrical drum and a distributor pump assembly, said drum having a wall, said wall having an upper part and an internal bearing surface, said assembly comprising a pump and a sealing sleeve, said pump having a normally closed intake valve, said method comprising the steps of:
- providing said assembly with a flexible skirt (4c);
- filling the drum with liquid product to a predetermined level; and
- inserting said assembly into the drum with said flexible skirt slideably engaging said wall until a lower face (4a) of said assembly comes into contact with a surface of said liquid product and then moves into said liquid product to force air and then a portion of liquid product contained in said drum between said flexible skirt and said wall; and
- sealing the dispenser with a reduction ring member; and
- moving said air and said portion of liquid product into an intermediate dead space between said assembly and said upper part.
- 4. The method for assembling a dispenser with liquid product, said dispenser comprising a cylindrical drum and a distributor pump assembly, said drum having a wall, said wall having an upper part, and said assembly comprising a sealing sleeve and a pump, said pump having a normally closed intake valve, said method comprising the steps of:
- providing at least one of said upper part of said drum and said assembly with an air escape passage;
- filling the drum with liquid product to a predetermined level;
- inserting said assembly into the drum with said assembly slideably engaging said upper part and forcing air out of said drum via said escape passage during said insertion;
- moving said assembly further into the drum until a lower face of said assembly contacts a surface of said liquid product; and
- forcing open said intake valve by continuing the moving of said assembly into said drum and moving said lower face into said liquid product to force a quantity of liquid product into said pump.
- 5. The method for assembling a dispenser with liquid product, said dispenser comprising a drum and a distributor pump assembly, said drum having a wall, said wall having an upper part, and said assembly comprising a sealing sleeve and a pump, said pump having a normally closed intake valve, said method comprising the steps of:
- providing at least one of said upper part of said drum and said assembly with an escape passage;
- filling the drum with liquid product to a predetermined level;
- inserting said assembly into the drum with said assembly slideably engaging said upper part and forcing a first portion of air out of said drum via said escape passage;
- moving said assembly further into the drum until a lower face of said assembly contacts a surface of said liquid product;
- moving said assembly still further into said liquid product to force a first quantity of said liquid product above said lower face into a space along an external bearing face of said sealing sleeve; and
- forcing open said intake valve by continuing the moving of said assembly into said drum and moving said lower face into said liquid product to force a second portion of air and then a second quantity of liquid product into said pump.
- 6. The method of claim 5 comprising the further step of:
- fitting one end of said drum with a movable base, said base being slideably engaged to said wall and arranged to move in an axial direction along said wall in a direction away from said one end,
- said movable base being fitted before the step of filling said drum with said liquid product to said predetermined level.
- 7. The method of claim 5 wherein said first quantity of liquid is sealed in an intermediate dead space between said sleeve and said wall.
