DOSING PACKAGE Russian patent published in 2003 - IPC

FIELD: creme composition dispensing equipment. SUBSTANCE: dosing package has casing equipped with creme composition storage chamber, creme composition dispensing opening, fixed cam arranged opposite said opening and provided with teeth extending tangentially to longitudinal axis, rotating ratchet mounted on cam for reciprocation and provided with ratchet teeth engageable with cam teeth. Ratchet is provided with outer peripheral teeth oriented in parallel with longitudinal axis. Drive screw is extending along central longitudinal axis between ratchet and opening and is fixed on ratchet for combined rotation therewith. Lifter is mounted on drive screw for movement between ratchet and opening to dispense said composition. Catch is positioned crosswise of longitudinal axis for engagement with peripheral cams and for rotating ratchet and drive screw on fixed cam. Control button is attached to catch for pressing it to peripheral cam. Control button is positioned in lower part of container by means of spring and mounting member. Immovable cam is mounted in lower part of container. Pressing of control button causes ratchet and drive screw to reciprocate relative to immovable cam, with reciprocal motion being transmitted to lifter through drive screw. Spring mounted between ratchet and lifter is adapted for pressing ratchet to immovable cam. Such construction provides quick pressure relief from package contents and, accordingly, prevents creme composition from penetration onto surface of applicator, which otherwise results in loss of product and contamination of applicator. Also, it eliminates penetration and leakage of creme composition through different parts of container and does not need the use of both hands during handling of package. EFFECT: simplified construction and increased convenience. 10 cl, 5 dwg
