本发明系关于分配器，详言之，系关于用于自一物质源分配一剂量之一气态、气体媒介或液滴物质之分配器及包含剂量计数器之分配器。;本发明因此提供一种用于自一物质源分配一剂量之一气态、气体媒介或液滴物质之分配器，该分配器包含：一本体，其用于收纳一物质源，该本体具有一吹嘴；一接合构件，其可滑动地配置于该本体中，用于在该本体之一纵向轴线上移动以自一物质源释放一剂量之一物质，该接合构件将一物质源之一喷口收纳于一插口中；及一分配器驱动器，其用于在该本体之该纵向轴线上移动该接合构件以自一物质源释放一剂量之一物质。一凸轮从动件可滑动地配置于该本体内，该凸轮从动件具有自一基底突出之刚性突起，且该突起配置于该分配器驱动器与该接合构件之间，使得由该分配器驱动器之凸轮施加至该突起的一力使该凸轮从动件可滑动地在该本体之该纵向轴线上移动且将一力施加至该接合构件以便自一物质源释放一剂量之一物质。该分配器亦包含一分配器帽，该分配器帽包含一中空本体，该中空本体具有可与该本体啮合之一下部开放端及一上部开放端，该上部开放端用于收纳一帽闭合装置以用于闭合该上部开放端。该分配器亦包含一剂量计数器，该剂量计数器用于指示对应于自一物质源分配的剂量之一数目的该分配器之一致动次数，或一物质源中剩余的剂量之一数目，该剂量计数器包含：一第一环构件，其具有一第一标志且可按增量围绕该纵向轴线旋转，该第一标志指示一计数；及一限制构件，其包含一限制机构，其中该限制机构包含一啮合部分，该啮合部分经配置以关于该第一环构件径向作用以接触该第一环构件以限制该第一环构件围绕该轴线相对于该限制构件之自由旋转。;The present invention therefore provides a dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source, the dispenser comprising: a body for receiving a substance source, the body having a mouthpiece; a junction member slideably arranged in the body for movement in a longitudinal axis of the body to release a dose of a substance from a substance source, the junction member receiving a spout of a substance source in a socket; and a dispenser driver for moving the junction member in the longitudinal axis of the body to release a dose of a substance from a substance source. A cam follower is slideably arranged within the body having rigid protrusions projecting from a base and the protrusion being arranged between the dispenser driver and the junction member such that a force applied by the cam of the dispenser driver to the protrusion causes the cam follower to slideably move in the longitudinal axis of the body and apply a force to the junction member so as to release a dose of a substance from a substance source. The dispenser also comprises a dispenser cap comprising a hollow body having a lower open end engageable with the body, and an upper open end for receiving a cap closure device for closing the upper open end. The dispenser also comprises a dose counter for indicating a number of actuations of the dispenser corresponding to a number of doses dispensed from a substance source, or a number of doses remaining in a substance source, the dose counter comprising: a first ring member having a first indicia and being rotatable in increments about the longitudinal axis, the first indicia indicating a count; and a limiting member comprising a limiting mechanism, wherein the limiting mechanism comprises an engaging portion arranged to act radially with respect to the first ring member to contact the first ring member to limit free rotation of the first ring member relative to the limiting member about the axis. |
