A device for delivering a medicated product or the like to a bodily cavity is provided. The device includes a barrel member having a distal end. The barrel member is sized to contain the medicated product. The device includes a plunger sized to extend into the barrel member. A cap is adapted to move between a sealing position, in which the cap is positioned adjacent to the barrel member and seals the distal end of the barrel member, and a dispensing position, in which the cap is moved in a direction away from the barrel member. The cap includes at least one opening sized to allow the medicated product to flow through the cap when the cap is in the dispensing position. A retainer mechanism is provided for retaining the cap on the barrel when the cap is in the dispensing position.本發明提供一種用以輸送含藥產品或類似物至體腔之裝置。此裝置包含具有末端之圓筒構件。圓筒構件之尺寸係被製造成包含含藥產品。此裝置包含柱塞,其尺寸被製造成延伸進入圓筒構件中。一蓋體係適合於在密封位置與分配位置之間移動,於密封位置中,蓋體係被安置成與圓筒構件鄰接並密封圓筒構件之末端,於分配位置中,蓋體係朝遠離圓筒構件之方向移動。蓋體包含至少一開口部,其尺寸被製造成允許含藥產品在蓋體處於分配位置時流經蓋體。當蓋體處於分配位置時,維持機構係提供作為將蓋體維持在圓筒上。10‧‧‧施配器12‧‧‧圓筒構件14‧‧‧螺旋蓋16‧‧‧柱塞18‧‧‧活塞20‧‧‧通道22‧‧‧壁面24‧‧‧近端部26‧‧‧遠端部28‧‧‧中間部30‧‧‧開放端32‧‧‧(帶肋之)表面34‧‧‧近端36‧‧‧末端38‧‧‧第一(環狀)定位環40‧‧‧第二(環狀)定位環42‧‧‧內螺紋44‧‧‧插入端46‧‧‧開放端48‧‧‧外壁50‧‧‧開口部52‧‧‧凹槽58‧‧‧內樁68‧‧‧(帶肋之)軸70‧‧‧拇指平台72‧‧‧近端74‧‧‧接觸平台76‧‧‧末端78‧‧‧(推拔)尖端80‧‧‧環狀部分82‧‧‧封閉推拔部分
