Abstract: A flow control structure such as is commonly referred to as a non-refillable closure which is primarily useful in minimizing the possibility of a bottle being refilled can be constructed so as to utilize two oppositely connected air traps in a passage which preferably also contains a ball-type check valve. The structure is intended to be mounted on the neck of a bottle so that in effect the passage serves as the bottle opening. When the bottle is in its normal upright position both one of the air traps and the check valve serve to prevent liquid from flowing into the interior of the container. When the bottle is in an inverted position in which at least part of the interior of the bottle is above the structure, the check valve is open as a result of the action of gravity and the air traps permit liquid to flow out of the bottle and air to flow into the container, but one of the air traps prevents liquid from flowing into the interior of the bottle.

Abstract: A manually operable dispenser pump construction wherein liquid product is received from a supply container into an axially compressible bellows. A product discharge assembly including a valve is associated therewith and adapted to move between open discharge and closed storage valve positions by collapsing movement of the bellows. In a preferred form of the invention, the bellows includes a trigger mounted to a relatively rigid front wall portion thereof. The bellows of such form is fluid sealingly snap engaged with a housing portion of the product discharge assembly and a pivot area about which the bellows front wall and the trigger move is formed by a thin wall area of the bellows disposed below its connection with the housing.

Abstract: A manually operable dispenser pump construction wherein liquid product is received from a supply container into an axially compressible bellows. The bellows in turn includes product discharge valve means associated therewith and adapted to move between open discharge and closed storage valve positions by movement of the bellows. In one form of the invention the product discharge valve valve includes a gooseneck portion integral with the bellows and which is moved out of closed position by said axial bellows compression. In another form the product discharge valve includes a generally circular gasket axially disposed between the bellows and its actuation means wherein said gasket is adapted to move into and out of sealing contact with a valve seat dependent on the compression of said bellows.
