Claims
- 1. A pump dispenser comprising:
- (i) a container of oval cross section having a closed and an open end storing a pumpable product;
- (ii) a pump means for drawing the product from the container and dispensing same, the pump means being positioned over the open end of the container and comprising:
- (a) a dip tube with upper and lower ends extending downward into the container for drawing product therefrom;
- (b) a collecting chamber for receiving product drawn upward from the dip tube;
- (c) a means interposed between the upper end of the dip tube and the collecting chamber for introducing air into the container;
- (d) an elastomeric wall at least partially positioned over and communicating with the collecting chamber, the elastomeric wall being resiliently pressable thereby compressing the collecting chamber;
- (e) a dispensing member communicating with the collecting chamber having an exit orifice through which product can flow outward, the dispensing member being shaped as a turret nozzle, the nozzle arranged at an upstream end to pivot through a vertical arc of at least 60.degree. from an outwardly pointing to a downwardly pointing direction; and
- (f) a one-way monitoring valve downstream from the collecting chamber controlling the outward flow through the dispensing member.
- 2. The dispenser according to claim 1 further comprising a check valve to regulate product flow, the check valve being positioned between the upper end of the dip tube and the collecting chamber.
- 3. The dispenser according to claim 2 wherein the means for introducing air and the check valve are lodged within a valve fitment.
- 4. The dispenser according to claim 1 wherein the elastomeric wall is domed.
- 5. The dispenser according to claim 4 wherein the elastomeric wall is of oval shape.
- 6. The dispenser according to claim 1 wherein a cap locking ring holds the elastomeric wall in place over the collecting chamber.
- 7. The dispenser according to claim 1 wherein the one-way monitoring valve is formed of an elastomeric rubber, flow through the valve being regulated by pressure exerted to open a normally closed exit slit.
- 8. A pump dispenser comprising:
- (i) a container for storing a pumpable product having a closed and an open end;
- (ii) a pump means for drawing the product from the container and dispensing same, the pump means positioned over the open end of the container and comprising:
- (a) a dip tube with upper and lower ends extending downward into the container for drawing product therefrom;
- (b) a collecting chamber for receiving product drawn upward from the dip tube;
- (c) a means interposed between the upper end of the dip tube and the collecting chamber for introducing air into the container;
- (d) an elastomeric wall at least partially positioned over and resiliently pressable downwardly thereby compressing the collecting chamber;
- (e) a dispensing member having an exit orifice communicating with the collecting chamber through which product can flow outward, the dispensing member being shaped as a turret nozzle, the nozzle arranged at an upstream end to pivot through a vertical arc of at least 60.degree. from an outwardly pointing to a downwardly pointing direction; and
- (f) a one-way monitoring valve downstream from the collecting chamber controlling the outward flow through the dispensing member.
- 9. A pump dispenser comprising:
- (i) a product container for storing a pumpable product having a closed and an open end;
- (ii) a pump means for drawing the product from the container and dispensing same, the pump means being positioned over the open end of the container and comprising:
- (a) a dip tube with upper and lower ends extending downward into the container for drawing product therefrom;
- (b) a collecting chamber for receiving product drawn upward from the dip tube;
- (c) a means interposed between the upper end of the dip tube and the collecting chamber for introducing air into the container;
- (d) an elastomeric wall at least partially positioned over and communicating with the collecting chamber, the elastomeric wall being resiliently pressable thereby compressing the collecting chamber;
- (e) a dispensing member communicating with the collecting chamber having an exit orifice through which product can flow outward; and
- (f) a one-way monitoring valve downstream from the collecting chamber controlling the outward flow through the dispensing member, the dispensing member being shaped as a turret nozzle, the nozzle arranged at an upstream end to pivot through a vertical arc of at least 60.degree. from an outwardly pointing to a downwardly pointing direction, the monitoring valve comprising an elastomeric rubber, flow therethrough being regulated by a pressure exerted to open a normally closed rubberized exit slit.
