Application filed October 19, 1912. Serial No. 726,599.

To all whom it may concern:

Be it known that we, Go'r'rFRInD BliHR and HAns DOBESOI-I, both citizens of Germany, residing at Schramberg and Stuttgart, Germany, respectively have invented certain new and useful Improvements in Containers Having Appliances for Discharging the Contents Thereof, of which the following is a specification.

This invention relates to containers such as cruets, more particularly mustard containers of the type in which the contents are forced out by means of a piston or plunger. In the mustard containers of this type heretofore designed, in which the plunger, after being depressed to discharge the mustard, is raised again by a spring and ascent sucks the mustard back from the discharge orifice, the plunger always returns to the same position. If this normal position of the plunger is above the level of the mustard the plunger is liable to discharge too much mustard while the container is well filled, and too little when the container is less full. If the'normal position of the plunger is in the mustard, and the plunger is arranged so that the length of its stroke does not vary, air penetrates to the space above the mustard, and causes the same to deteriorate.

The object of the present invention is to remove these disadvantages and to provide a mustard container wherein the extruding plunger always lies above the mustard but is, after each extrusion, only withdrawn to an extent suflicient to suck the mustard away from the discharge orifice.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical section showing one embodiment thereof. Fig. 2 is a vertical section showing another embodiment, and Fig. 3 shows a detail thereof in another position. Figs. 4 and 5 are views corresponding to Figs. 2 and 3 showing a modification.

Referring in the first place to Fig. 1, a is the container, which has a discharge-orifice b, and is closed at the top by a screw cover a; (Z is the piston or plunger attached to the rod 6. The latter is screwed at its upper end to a knob 9 against which bears a spring h coiled upon the rod 6. The lower end of the coiled spring abuts against a shoulder inside a sleeve 2', in which the rod 6 is slidable and rotatable. The sleeve 2' is slidable in a boss 70 on the cover 0, but is embraced and gripped by a spring ring on which is arranged in a groove inside the said boss 72. The sleeve 2' is of such length that a short depression of the knob 9 causes the latter to abut against the upper edge of the sleeve. When the knob g and the plunger are depressed for the purpose of discharging mustard, the spring I). is compressed. If the pressure transmitted by the spring h to the sleeve 73 exceeds the force with which the ring m grips the sleeve or if the knob. g is thrust down sufliciently to abut against the upper end of the sleeve and depress the same, the sleeve takes part in the latter portion of thedownward move ment of the plunger. When the knob g is then released, the sleeve 2' remains stationary, whereas the plunger is raised by the spring it until it abuts against the lower edge of the sleeve 2'. By this slight upward movement of the plunger d, the mustard is sucked away from the orifice b. It will be seen that each return stroke of the plunger after discharging mustard, is somewhat shorter than the previous downward stroke. Accordingly, the plunger follows the descending level of the mustard in the container. In stead of being at the bottom of the container, the discharge orifice may be at the side.

In the construction shown in Figs. 2 and 3, the plunger (Z in the container 64 has a rod 0 extending upward through a hole in the boss 79 on the cover 0 the arrangement of these parts being exactly similar to that of the corresponding parts shown in Fig, l. The rod 6 however, has a screw thread 1 of very coarse pitch at its upper part, and has a crank 2 fixed to its upper end, this crank being connected by a coiled spring hi to the sleeve '5 The latter is in part internally screwed, to engage with the screw 1, and is also externally screwed, to engage with the tapped boss 7: The plunger 01 is normally held against the lower end of the sleeve 2' by the action of the spring [2, which tends to screw the rod 6 upward in the sleeve. When the crank 2 is turned against the action of the spring h the plunger rod 0 descends inside the sleeve i until the spring 72. has been fully compressed, as shown in Fig. 3, whereupon further rotation of the crank rotates the sleeve 2' and causes it to screw downward through the cover When the crank 2 is released, after the dis charge of the required amount of mustard, the sleeve 2' remains stationary whereas the rod 0 with the plunger d is screwed upward by the action of the spring k until the plunger abuts against the lower edge of the sleeve.

The device shown in Figs. 4, and 5 is similar to that shown in Figs. 2 and 3, except that a coiled plate spring it is substituted for the wire spring N.

The container may be made of china, glass, "celluloid or the like, and the plunger of cork or other suitable material. The springs and the ring m are preferably made of steel.

V \Vhat we claim as our invention and desire to secure by Letters Patent of the United States is 1. The combination, with a container having a discharge orifice, of a plunger movable in said container toward and from said orifrom said orifice, an abutment movably engaged with said container in the path of said plunger from 'said orifice, and means whereby movement of said plunger toward said orifice imparts movement to said abutment after said plunger has traversed part of its path.

2. The combination, with a container having a discharge orifice, of a plunger movable in said container toward and from said orifice, a plunger rod extending out of said container, a movable sleeve embracing part of said rod and frictionally engaged with said container, and a spring engaged with said sleeve and said rod, allowing limited movement of the latter in said sleeve and tending to move said plunger from said orifice.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
