A blister package (1) with a bottom part (2) with at least one depression (3) and a cover film (6) that is fastened to the bottom part (2), covers the depressions (3) and can be forced through, the depressions (3) containing a product to be withdrawn. A cover layer (7) covers the cover film (6) and contains sections that can be forced through and others that cannot be forced through. The depression (3), in the rest position of the blister package (1), is located at least partially or completely above a section of the cover layer (7) that cannot be forced through. In order to expose the product to be withdrawn, the depression is displaced across a section (8) in the cover layer (7) that can be forced through by way of a lateral movement with respect to the cover layer (7). The product to be withdrawn can then be forced through the cover film (6) and the cover layer (7).

The method of operation in cycles of a lubricant injector comprising a body having an inlet for lubricant under pressure, an outlet, a measuring chamber for receiving lubricant from the inlet, a piston movable through a stroke in the measuring chamber for the discharge of a measured volume of lubricant from the measuring chamber and thence through the outlet, and a valve responsive to pressure conditions in the inlet, each cycle starting with the injector in a state of repose wherein the pressure of lubricant in the inlet is relieved and the measuring chamber is charged with lubricant, increasing the pressure in the inlet for actuating the valve placing the injector in a state for the discharge, and ending with relieving pressure in the inlet placing the injector in a state for venting the injector to effect recharging of the measuring chamber involving the transmission of lubricant from the inlet to the measuring chamber. 7. The method of claim 6 wherein the valve is at a first position during said state of repose and a second position during said discharge, and wherein said method further comprises configuring the valve so that it is urged from said second position back toward said first position by back pressure of lubricant in the outlet. 8. A lubricant injector comprising a body having an inlet for lubricant under pressure from a supply, an outlet, a measuring chamber for receiving lubricant from the inlet, a piston movable through a stroke in the measuring chamber for discharging a measured volume of lubricant therefrom, said injector having passaging for transmission of lubricant from the inlet to the measuring chamber and transmission of lubricant from the measuring chamber to the outlet, a valve movable between a first position for the transmission of lubricant from the inlet to the measuring chamber and blocking the transmission of lubricant from the measuring chamber to the outlet and a second position for blocking the transmission of lubricant from the inlet to the measuring chamber and for the transmission of lubricant from the measuring chamber to the outlet, said valve being biased to move from its second to its first position and responsive to certain pressure of lubricant in the inlet to overcome the bias and move from its first to its second position, said injector being operable in cycles each of which involves the injector initially being in a first state due to relief of pressure in the inlet, in which state the valve is in first position and the measuring chamber is charged with lubricant, the injector progressing to a second state on increase of pressure in the inlet sufficient to overcome the bias and move the valve to its second position, then progressing to a third state upon further increase in pressure in the inlet for discharging said volume, and finally a fourth state upon drop of pressure in the inlet wherein the valve is in its first position for venting the injector to effect recharging of the measuring chamber involving the transmission of lubricant from the inlet to the measuring chamber. 9. A lubricant injector as set forth in claim 8 wherein the valve is at a first position during said state of repose and a second position during said discharge, said injector comprising at least one spring for biasing the valve toward said first position, said valve further being configured to be urged from said second position back toward said first position by back pressure of lubricant in the outlet. 10. The method of operation in cycles of a lubricant injector which comprises a body having an inlet for lubricant under pressure from a supply, an outlet, a measuring chamber for receiving lubricant from the inlet, a piston movable through a stroke in the measuring chamber for discharging a measured volume of lubricant therefrom, said injector having passaging for transmission of lubricant from the inlet to the measuring chamber and transmission of lubricant from the measuring cha
