An assembly method of an apparatus suitable for pressurized liquid transfusion is disclosed. In one step, a nozzle is to be inserted into the through hole of an elastomeric ring. Because the dimension of the nozzle is larger than the through hole, the internal wall of the elastomeric ring is tensioned and deformed so as to fit the nozzle. In one step, the elastomeric ring along with the nozzle is inserted into a receptacle. The dimension of the outer contour of the elastomeric ring needs to be decreased so as to be accommodated by the receptacle. Due to the flexibility of the elastomeric ring, it resumes at least partially to its original shape. Therefore, proper seal is created and maintained between the elastomeric ring and the nozzle such that leakage and pressure loss may be prevented. The foregoing is capable of working under high-pressured environment for prolonged use.

A reservoir for a nebulizer includes: a tank or bag containing multiple doses of a fluid to be nebulized, and an indicator device for counting or indicating a number of uses performed or still possible with the reservoir, where at least one of: the reservoir includes a connector for fluidically connecting the tank or bag with the nebulizer, the indicator device is actuated by moving the connector relative to the tank or bag, and the reservoir includes or forms an eccentrical linear guidance for a driving part for driving the indicator device.

An elastic member for a pump assembly is provided. The elastic member may include an upper support; a lower support provided under the upper support; and a connection part which connects the upper support and the lower support, and in which peaks and valleys are repeatedly formed in an outward direction to be bent when the elastic member is pressurized.

An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.

A dispenser for dispensing flowable masses has a reservoir and a modular dispenser pump with an input channel, an output channel and a pump chamber. A head piece is provided and has a dispensing opening and a dispensing channel. The dispenser pump can be inserted into the reservoir and can be connected to the reservoir by a locking connection. The pump chamber is formed by a piston and a cup part. The piston is slidably accommodated in the cup part. The cup part has fastening formations for fastening interaction with an inner wall of the reservoir. The locking connection is provided by two radially outwardly protruding locking beads, which are spaced apart from one another in the vertical direction. The locking beads are designed with an insertion rounding on the reservoir side and with a substantially horizontal contact surface with respect to the longitudinal section on the head piece side.

A dispensing device (100) according to the invention comprises a reservoir (4) for a liquid or semi-liquid substance to be dispensed and a pumping mechanism (5) for dispensing the substance. The device is characterized in that it includes a housing (1), in which an upper body (2) and a lower body (3) are located, wherein a deformable reservoir (4) is located on or around the lower body (3) and the pumping mechanism (5) is located in the upper body (2). A supply valve (6) and a dispensing valve (8) are located in the lower body (3), and the supply valve (6) is connected by means of a lower channel (7) with the reservoir (4), and a dispensing valve (8) is connected by means of an upper channel (9) with the pumping mechanism (5).

A dispensing container for discharging different types of contents includes a first container, a second container, a first pump module coupled to the first container, and a second pump module coupled to the second container. The first container includes an insertion space and a first interior space separated from the insertion space by a partition wall. The second container is inserted into the insertion space and includes a second interior space. The first pump discharges a first content filled in the first interior space, and the second pump module is inserted into the second interior space when the second container is inserted into the insertion space. The second pump module also discharges a second content filled in the second interior space.

The present disclosure relates to a spring for a pumping-type container having a first helical part and a second helical part, and a pumping-type container including the same, and has been made to solve a problem caused by independent elastic deformation of the first helical part and the second helical part.

The present disclosure relates to a pumping-type container, and is to solve the problem of a discharge opening/closing part in which the force of pressing a button toward a cylinder is great and the assembly operation thereof is difficult. To this end, a discharge opening/closing part may be configured to have an elastic deformation opening/closing part which is made of an elastic material and has an opening/closing cutting line thereon, and is detachably coupled to the button such that the elastic deformation opening/closing part closes the end of the button discharge channel part.
