A vessel having a dispensing closure; a container engaged with the dispensing closure and having a pair of opposed walls defining a bore for receiving the product and having a relaxed state, the container being repeatedly squeezable to inwardly deflect from its relaxed state to cause the opposed walls to deflect inwardly to displace some of the product from the container into the dispensing closure for dispensing one of the predetermined amounts of product and being flexible to return its relaxed state after squeezing, and a limiting member disposed within the bore for limiting inward deflection of the opposed walls during each squeezing of the container to limit the amount of product displaced from the container into the dispensing closure. The limiting member has an H-shaped cross section substantially along its length.

1. A vessel configured to contain liquid, semi-solid or powder product and to dispense predetermined amounts of the product, the vessel comprising a dispensing closure defining a flow opening;a container engaged with the dispensing closure having a relaxed state, the container being squeezable to inwardly deflect the container from its relaxed state to displace some of the product from the container into the dispensing closure for dispensing through the flow opening one of the predetermined amounts of the product and being flexible to return to its relaxed state after the squeezing, the container thereafter being squeezable to inwardly deflect the container from its relaxed state to displace some more of the product from the container into the dispensing closure for dispensing an other of the predetermined amounts of product through the flow opening and being flexible to return to its relaxed state after the squeezing, the container includes a pair of opposed walls that are squeezable towards each other; anda limiting member for limiting inward deflection of the container during each squeezing of the container to limit the amount of product displaced from the container into the dispensing closure and to enable the same amount of product to be dispensed with each repeated deflection of the container, the limiting member is disposed between the opposed walls and has a length that extends in substantially the same direction as a longitudinal axis of the container, the limiting member has an H-shaped cross section along at least a portion of its length. 2. The vessel of claim 1 wherein the limiting member has the H-shaped cross section substantially along its length. 3. The vessel of claim 1 wherein the limiting member includes a pair of rigid members each having a width that extends between the pair of opposed walls and each having a pair of opposed ends, the ends configured to contact the opposed walls during squeezing of the container to limit the inward deflection of the opposed walls. 4. The vessel of claim 3 wherein the rigid members each have a length that extends in substantially the same direction as a longitudinal axis of the vessel. 5. The vessel of claim 3 wherein the rigid members are substantially parallel to each other and wherein the limiting member further includes an interconnecting member interconnecting the two rigid members. 6. The vessel of claim 5 wherein the interconnecting member has a width extending generally perpendicular to the widths of the rigid members and has a length that extends in substantially the same direction as the longitudinal axis of the container. 7. The vessel of claim 1 wherein the opposed walls are arcuate and are symmetrical to each other about a longitudinal axis of the vessel. 8. The vessel of claim 1 wherein the container defines a bore and the limiting member is disposed within the bore. 9. The vessel of claim 8 wherein the dispensing closure further includes a living hinge secured to the overcap. 10. The vessel of claim 1 wherein the dispensing closure includes an overcap movable between open and closed positions to open and close the flow opening. 11. The vessel of claim 1 wherein the length of the limiting member is substantially the same as a length of the container. 12. The vessel of claim 11 wherein the limiting member extends from a base of the container to adjacent an end of the container. 13. A re-fillable and re-useable vessel configured to contain a liquid, semi-solid or powder product and to dispense predetermined amounts of the product, the vessel comprising a dispensing closure defining a flow opening;a container engaged with the dispensing closure and having a pair of opposed walls defining a bore for receiving the product and having a relaxed state, the container being squeezable to inwardly deflect from its relaxed state to cause the opposed walls to deflect inwardly to displace some of the product from the container into the dispensing closure for dispensing one of the predetermined amounts of product through the flow opening and being flexible to return its relaxed state after squeezing, the container thereafter being squeezable to inwardly deflect from its relaxed state to cause the opposed walls to deflect inwardly to displace some more product from the container into the dispensing closure for dispensing an other of the predetermined amounts of product through the flow opening and being flexible to return its relaxed state after squeezing; anda limiting member disposed within the bore between the opposed walls for limiting inward deflection of the opposed walls during each squeezing of the container to limit the amount of product displaced from the container into the dispensing closure and to enable the same amount of product to be dispensed with each repeated deflection of the container, the limiting member has a length that extends in substantially the same direction as a longitudinal axis of the vessel and has an H-shaped cross section along at least a portion of its length. 14. The vessel of claim 13 wherein the limiting member includes a pair of spaced apart rigid members, each rigid member having a width that extends between the pair of opposed walls and having a pair of opposed ends, the ends configured to contact the opposed walls during squeezing of the containers to limit the inward deflection of the opposed walls, each rigid member having a length that extends in substantially the same direction as a longitudinal axis of the vessel. 15. The vessel of claim 14 wherein the rigid members extend substantially parallel to each other and wherein the limiting member further includes an interconnecting member interconnecting the two rigid members. 16. A vessel configured to contain liquid, semi-solid or powder product and to dispense predetermined amounts of the product, the vessel comprising a dispensing closure defining a flow opening;a container having an end with the dispensing closure coupled thereto, the container having walls that are squeezable to inwardly deflect the container from its relaxed state to displace product from the container into the dispensing closure for dispensing through the flow opening and being flexible to return to its relaxed state after the squeezing,the container having an opposite end coupled to the walls; anda limiting member having a length that extends in substantially the same direction as a longitudinal axis of the container for limiting inward deflection of the container during each repeated squeezing of the container to limit the amount of product displaced from the container into the dispensing closure and to enable the same amount of product to be dispensed with each repeated deflection of the container, the limiting member having first and second parallel rigid members disposed between the opposed walls when the container is in its relaxed state and with a third rigid member joined to each of the first and second parallel rigid members so as to prevent movement of the first and second parallel rigid members with respect to each other during each repeated deflection of the container.
