OIL DISPENSER Filed May 4, 1946 I N V EN TOR:

ATTORNEY Patented Get. 21, 1947 UNITED STATES FATENT OFFICE Claims.

My invention relates to dispensers for oils or other liquids and, more particularly, to receptacles having an opening for the reception of a quantity of liquid and having another opening, preferably a nozzle, for the discharge of the liquid.

Due to the viscidity of the liquid and to other reasons, the discharge is never absolutely complete, a portion of the liquid remaining at the inner surface of the nozzle and of other parts of the receptacle. Later, this remaining liquid is apt to drip from the receptacle and to soil or spoil the place Where the receptacle has been placed. Thereby, also the outer surface of the receptacle may be soiled and the receptacle can. not be handled a second time without soiling the hands. An object of my invention is to avoid these drawbacks and to prevent any drippage of liquid when the receptacle is not used or has been put away.

Another object is to avoid any loss of liquid.

Further objects are to obtain these results reliably and with simple means, and to provide a structure which can be inexpensively made and easily handled.

Still other objects and advantages will appear from the following description of an exemplifying embodiment of my invention, from the appended claims and from the accompanyin drawing in which:

Fig. 1 shows a cross-section of an illustrative embodiment of my invention in that position in which the dispenser is placed when not used, this cross-section being taken along the line ll in Fig. 2.

Fig. 2 shows a cross-section taken along the line 22 in Fig. 1.

Fig. 3 shows a cross-section taken along the line 3-3 in Fig. 1.

Fig. 4 shows a side view of the same embodiment in a position in which the dispenser is used for discharging oil,

Referring to the drawing, numeral 4 lnicates a housing containing a preferably cylindrical main chamber 5 and a drip chamber 6 positioned at one side of the chamber 5 and separated therefrom by a partitioning wall 1 which extends from one longitudinal side line of the housing to another. Preferably, the drip chamber 5 has a lunar cross-section adjacent to an arc of the Wall of the main chamber 5 whereby the entire crosssection of the housing has a slightly elongated and well rounded shape adapted for convenient handling.

The chamber 5 has a Wide opening 8 at the base of the housing 4 or at that side which is at the bottom in Figs. 1 and 2 and which is turned u in the position of use shown in Fig. 4. The opposite side of the housing is closed by an end or top wall H0. The wall I does not reach to the end wall l0, leaving a gap near this end wall.

Another, inner end wall 9 may be arranged at a small distance from the wall Ill. The wall 9 extends from the wall 1 across the main chamber 5. A space H is located between the end walls *9 and ID and communicates with the drip chamber 6.

The wall 9 has an outlet or opening I2, and the wall in has an outlet or opening l3. The openings i2 and [3 are positioned eccentrically at the same side of the receptacle or housing as the drip chamber 6 and about at the center of the are formed by this drip chamber. The edges of the opening 12 are preferably raised or bent in the direction to the chamber H. A pipe I4 is affixed to the wall Ill and around the Opening l3. The pipe may be suitably curved or bent and terminates in a nozzle l5.

In addition to the drip chamber 6, the housing 6 may contain an inner drip chamber It formed by a cylindrical partitioning wall H which projects from the rim of the opening 8 to the inside of the housin and terminates at some distance from the Wall 9.

Preferably, the receptable is charged with a container l8 (Fig. 4) of conventional type which contains the liquid to be dispensed. The container I8 has a cylindrical shape and is completely sealed, one fiat end wall of the container being periorable or tearable. The opening 8 fits the cross-section of the container l8 or is slightly larger than the latter. Preferably, the container 58 is introduced into this opening in sealed condition, the perforable side being inserted first, and this side is opened by means provided in the interior of the chamber 5.

These means may comprise one or several knives or cutters projecting from the wall 9 to the interior of the chamber 5 in a direction to the opening 8. For example, a cutter l9 may be made of a rectangularly bent strip of sheet metal. One arm of the strip i9 runs parallel to and is affixed to the wall 9. The other projects about parallel to the wall 1 and terminates in an edge 28 adapted to out orbreak through the perforable side of the container 18. Another butter 2! may v a p r s mflarly amxed to the ball .9 or to. the adjacent part of the strip 19, may project in an oblique direction and terminates ina cutting edge '22. Preferably, the cutter '2l projects less far than the cutter iii. A third cutter 23 may be affixed to a broad side of the cutter Z! in a position where the broad sides of the cutters 2i and 23 are perpendicular to each other.

Rivets

24 and 25 may be used to connect the cutters with the wall 9. These rivets may pass through the walls 9 and I and may have necks of enlarged diameters positioned between these two walls.

The dispenser is used in a position in which the nozzle 15 points downward. The container I8 is pushed into the opening 8. Hereby, the edge 20 perforates the container It at a spot near the containers cylindrical wall. From then on, the projecting part of the cutter l9 acts as a guide for the further insertion of the container. During this further insertion, the cutters 2| and 23 perforate the central part of the perforable wall of the container l8, creating a Wide opening therein through which the liquid can readily fiow to the opening [2 and farther through the opening l3, the pipe l4 and the nozzle l5.

When the liquid has been dispensed or discharged in this manner, the emptied container i8 is removed. Then, the dispenser can be returned into the position shown in Figs. 1 and 2 and can be placed in this position without any drippage from the opening 8. Any liquid that may have remained in the pipe [4 will run along the walls of this pipe into the drip chamber 6 where it will stay until further use and reversal of the dis- If liquid should enter the chamber H, for example, because the dispenser has been occasionally tilted when handled, this liquid will not pass through the opening l2, but will flow around the raised edge of this opening into the chamber 6.

If, by any chance, liquid should run from the wall 9 down the walls of the chamber 5, this liquid will be intercepted by the drip chamber It. If the dispensed liquid is not substantially viscid or adhesive and if a considerable quantity of this liquid has remained in the pipe 14, this remained liquid may form drops which fall through the opening l3. Such drops will either fall into the drip chamber 6 or, if they pass the opening l2, into the drip chamber l6. Either the wall 1 or the wall I! is positioned at least as far inwardly as the innermost part of the opening l3 whereby no drops falling through this opening can reach the opening 8.

If the wall 1 is positioned sufiiciently inward, or if a sufliciently viscid liquid is dispensed, the chamber I is not absolutely necessary. So, in certain cases, the wall I1 or the chamber l6 may be omitted or may be provided merely as an additional security against drippage.

I desire it understood that my invention is not confined to the particular embodiment shown and described, the same being merely illustrative, and that my invention may be carried out in other ways without departing from the spirit of my invention as it is obvious that the particular embodiment shown and described is only one of the many that may be employed to attain the objects of my invention.
