  • Patent number: 8142390
    Abstract: A syringe device (1) with an elongate plunger space (2), a receiving chamber (3) for receiving solid medicaments (4), and a hollow needle (5) arranged in the plunger space (2), and also a plunger (7) which is suitable for movement in the plunger space (2) and bears a ram (8) for pushing out the solid medicament (4). For displacement of the plunger (7) there is a plunger rod (9) which acts thereon and, for its use, can be extended telescopically out of the plunger space (2) and relative to the plunger (7) and can be coupled to the plunger by means of a lock (10). The locking of the plunger (7) to the plunger space (2) is opened or released only by complete withdrawal of the plunger rod (9) in its operative position while at the same time the plunger rod (9) is coupled to the plunger (7) in this position in the pushing direction such that the medicament can then be pushed out.

  • Patent number: 5152434
    Abstract: A dispenser has a pump device (4) with two hollow pistons (9, 10) which are displaceable coaxially with respect to each other, and wherein one piston is seated at the pump base while the other piston is seated on an actuating button (30). The button continues into a mouthpiece (29) and is surrounded by a bellows (B) which provides an axial restoring force. The bellows (B) forms a piston ring (K) at a distance (A) from the upper end of the actuating button-side hollow piston (9), and slides on a wall surface (b 9') of the button side hollow piston.

  • Patent number: 5042694
    Abstract: A dispenser for pasty compositions has a delivery tube (3) with lateral passage openings (10) for a second component of a pasty composition developed in the delivery tube (3), and an elastically reformable pump element. The delivery tube (3) is closed by a valve body (19). A piston (33) is moveable through a housing of the dispenser in emptying direction upon reforming of the pump element. The lateral passage openings (10) for the passage of the second component can be closed by the same valve body (19), and the valve body is guided by means of a shaft in the delivery tube (3). In order to obtain in a manner simple to manufacture, a dispenser for pasty composition for possible delivery of pasty composition formed of several components, particularly an esthetically pleasing stripe formation, a stepwise widening of the delivery tube cross section which is developed in the direction of flow at the height of the upper valve-disk closure. Guide ribs for mating with the valve-disk.
