A bag in squeeze bottle fluid dispenser capable of dispensing substantially all of the fluid product contained therein. A suitable bag support element is inserted inside the flexible bag to prevent substantial axial movement of the bag in the direction of its discharge orifice and to encourage radial collapse of the bag instead. The internal bag support means, which in a preferred embodiment comprises an extruded plastic helix, has an internal fluid passage formed within the coils of the helix and fluid communication to allow fluid contained within the bag to access the internal fluid passage along substantially the entire length of the internal bag support element. Thus, radial collapse of the flexible bag does not block the passage of fluid remaining in the bag through the discharge orifice in the bag until substantially all of the fluid contained within the bag has been dispensed. In a particularly preferred embodiment, the internal bag support element is inserted into the dispenser through the discharge orifice of the bag to a point substantially coinciding with the opposite end of the flexible bag after the bag has been filled with the fluid to be dispensed.

A dispensing package which automatically relieves residual pressure on a cream product and dispenses this product in incremental doses is disclosed. The package uses a feed screw to drive an elevator which impels the cream product in a unidirectional manner. The drive of the feed screw is superimposed with reciprocatory motion caused by internal cams which retract the elevator. By intermittently retracting the elevator a suitable distance, discrete amounts of the product are dispensed for each cycle and the residual pressure on the product is relieved, preventing it from weeping onto the applicating surface of the dispenser. The dispensing package is well suited to contain and dispense cream deodorants and antiperspirants.

A strong laminate with improved tear resistance properties and excellent delamination resistance is disclosed. The laminate comprises a tear strength reinforcing nonwoven center bonded to outer ply tissues utilizing discontinuous thermoplastic masses with controlled penetration of the thermoplastic into the center ply layer.
