Measuring and dispensing cap with internal measuring chambers

摘要

In an apparatus for measuring and dispensing pourable material, a removable cap includes a body, a cylindrical sleeve member sheathing an outer circumference of the body, and a biasing spring engageable between the body and the cylindrical sleeve member for biasing the cylindrical sleeve member toward a predetermined home position. The body can include chambers separated longitudinally from one another by a radial panel defining an arcuate aperture allowing passage of the pourable material between the chambers. The cylindrical sleeve member is rotatable with respect to the body for aligning at least one of a plurality of measuring compartments defined by the cylindrical sleeve member with the arcuate aperture for allowing pourable material flow therethrough. The biasing spring can close access to the plurality of measuring compartments during dispensing of a predetermined amount of the pourable material.

1. In an apparatus for measuring and dispensing pourable material having a removable cap, the improvement of the cap comprising:
a body having a cylindrical sidewall defining a primary axis, a first chamber and a second chamber separated longitudinally from one another by a radial panel extending transversely with respect to the primary axis, the radial panel defining an arcuate aperture allowing passage of the pourable material from the first chamber to the second chamber; a cylindrical sleeve member located coaxial with respect to the primary axis and sheathing an outer circumference of the cylindrical sidewall of the body, the cylindrical sleeve member defining a plurality of measuring compartments defined by dispensing chambers received within the second chamber of the cylindrical sidewall of the body, the cylindrical sleeve member rotatable with respect to the cylindrical sidewall of the body for aligning at least one of the plurality of measuring compartments with the arcuate aperture of the body for allowing pourable material flow therethrough for measuring a predetermined measured amount of the pourable material within measuring compartments aligned in fluid communication therewith; and a biasing spring engageable between the body and the sleeve member for biasing the sleeve member toward a predetermined home position with respect to the body with the radial panel closing access to the plurality of measuring compartments during dispensing of the predetermined measured amount of the pourable material.
