A dental powder/liquid material-containing preparation accommodation bag, which suppresses entrainment of air in mixing a powder material and a liquid material for dispensing, is provided. A powder materialis accommodated in a powder material accommodation chamberof a bag body, while a liquid materialdissolving the powder materialand changing into a pasty form, in cooperation with the powder materialis accommodated in a liquid material accommodation chamberpartitioned from the powder material accommodation chamberby a weakened section. The weakened sectionis ruptured by applying a pressing force to the bag body. As a result, the powder material accommodation chamberand the liquid material accommodation chambercommunicate, to feed the liquid material accommodated in the liquid material accommodation chamberinto the powder material accommodation chamber. Then, the powder materialand the liquid materialchanging into the pasty form are pressed within the powder material accommodation chamberfrom the surfaces of the bag bodyfor dispensing.

Dental powder/liquid material-containing preparation accommodation bag and dispensing method for same

[Problems] To fill a container with a material without applying a high pressure to the material that is to be filled. [Means for Solution] An ejection devicecomprises a filling chamberformed in a cylindrical member for containing a material to be filled, a discharge portionhaving a discharge nozzlefor pouring out the filled material to the exterior, and a pistonthat pushes the filled material toward the front end side of the filling chamberto discharge the filled material through the discharge nozzle. In the ejection device, the discharge portionis formed separately from the filling chamberand in a manner to be fitted to an opening on one end side of the cylindrical member, the opening serving as a filling port for filling the material to be filled, and after the material to be filled is poured into the filling chamberthrough the filling port, the discharge portionis coupled to the filling chamber

Ejection device and method of filling the ejection device with a material

[Problems] To provide an ejection container capable of falling a liquid in drops from the container body without relying on the sense of the fingertips and without affected by a change in the temperature. [Means for Solution] A knock-type ejection containerin which an ejection portis provided at one end of a container body, a knock buttonis provided at the other end thereof, a container chamberis provided in the container bodyto contain a liquid, and the liquid contained in the container chamberis ejected from the ejection portbeing interlocked to the operation of the knock button

Knock-type ejection container

A container which is not bulky at the time of shipping and can be stably stood on a suitable place. The container includes a lid member for closing a take-out opening (brittle portion) of the container body. On the lower outer side of the container body, there are formed slits for fitting the lid member to the container body after the container body and the lid member are separated apart, and auxiliary leg portions that protrude outward of the container body. The lid member is forming holding leg portions that protrude outward therefrom. Wing portions of the holding leg portions are inserted in the slits to fit the lid member to the container body, and the erected attitude of the container body is supported by the holding leg portions.
