in order to assure a full measure, as is now the According to my present invention, I provide case, to .Ov fi e Container by e amount in the container suitable means for fracturing 5 which would normally adhere to the walls thereof. th n p ckage s it; is inserted therein, Pref- ,5-

A still further object of this invention is to erably, these means comprise aplurality of prongs p v i a dispenser of the type a ove deor spikes l8 secured adjacent the bottom of the scribed means to fracture and shred the cont i r i y w n known ann r, si a tai e a i is being positioned in the dispenser will be appreciated from an inspection of Fig. 1, so that the same cannot be refilled with other oil. the container I0 is only slightly larger than the These and other O je y p s ve oil package l9, there will be no tendency for the tion will become more apparent from a study of oil package to fall away from the spikes or the following description taken in connection prongs. By this construction, once the oil packwith the accompanying drawings in which age is fractured, it will be impossible to use it Fig. 1 is a side elevation of the one form again for refilling purposes so that the package 55 comprises essentially a single use oil package and the danger of having the container refilled with adulterated oil is minimized and, for all practicable purposes, avoided.

In order to insure the complete removal of the oil from the package, I have provided means to collapse the package as it is being removed from the dispenser so that when the package is completely removed, the oil will have been removed therefrom. Referring now more particularly to Figs. 2 and 3, there is shown a frame hinged to the container by hinges 2!, so that when it is desired to use the dispenser, the frame may be swung out of the way of the package being placed therein. After the package has been placed in the dispenser, the frame is swung into the position illustrated in Fig. l. Extending across the open mouth of the container l0 and rigidly secured to the frame at either end is a bar 22 against which the top of the package may be forced by a bar 23 slidably connected at either end to the frame 20. In order to force the slidable bar against the fixed bar, I have provided a plunger 24 pivotally secured to the fixed bar and extending through a guide 25 carried by one end of the frame and, preferably, that end of the frame hinged to the container 10. In order to facilitate the manipulation of the plunger. a conventional push button 26 may be secured thereto. The bar 23 may also be provided with prongs 23 which serve to shred or rip the oil package as it is being withdrawn from the container Ill and thereby prevent. any possible reuse of the package. It will be noted that the relation between the handle I! and the button 26 and the plunger is such that the operator may force the slidable bar against the top of the package positioned there with one hand leaving the other hand free to pull the container be m tween the fixed and movable bars so that the oil in the package l9 will be removed therefrom as the said package is being drawn between the fixed and movable bars.

Referring now to the modification illustrated in Figs. 4 to '7 inclusive, there is shown a dispenser comprising a container 21 provided with a bottom 28, which is preferably tapered so as to direct a flow of the oil toward the dispensing opening 29 to which is connected at flexible hose or tube 30 provided with a conventional form of nozzle 3|. A clip 32 is attached to one wall of the container so as to provide means: for holding the hose 30 in inoperative position, as shown in dotted outline in Fig. 4. As will be appreciated. the hose is swung into the position shown, as indicated in full line in Fig. 4. the nozzle being inserted in the crank case of an internal combustion motor in the well known manner. If desired, the container may be provided with depending members 33, forming legs to support the container in upright position. A handle 34 is also provided and, as was the case in the modification shown in Figs. 1 to 3 inclusive, the handle is secured to the container in such relation to the operating parts of the dispenser that the attendant may fill and operate the dispenser with one hand. Secured to the top of the container is provided a pair of brackets 35 on which is mounted a roller 36. Cooperating with the roller 36 and relatively movable with respect thereto is provided a roller 31 journalled in the free ends of a pair of arms 38 pivotally mounted to the container by studs 39. Secured to one of the arms 38 is a lever 40 provided with a portion forming a handle for manipulation by the thumb of the attendant. The roller 31 is constantly urged toward the roller 36 by means of a spring 4!.

In the operation of the device, the oil package 42 containing oil 43 is dropped into the container l0, which may or may not be slightly larger than the oil package, the limiting feature being that the container I0 is always'larger than the oil package. When the package is dropped into the container, the bottom thereof will contact with a spike or prong 44 positioned adjacent the opening 2| in the bottom of the container and, due to the weight of the oil and the flexibility and thinness of the material from which the oil container was formed, the spike or prong will force itself through the bottom of the oil package. The attendant then releases lever 40 and, due to the force of the spring, the roller 31 will be brought into contact with the oil package, thus squeezing the walls of the oil package together. As the attendant (Fig. 5) draws the oil package between the rollers, the force of the spring 4| will compress the oil package, thereby forcing the oil through the opening formed by the spike or prong 44. In this manner, all of the oil will be removed from the package by the time the said package is finally drawn between the rollers 36 and 31. Prongs similar to prongs 23' may be provided adjacent the top edge of the container 21 and in line with the oil package.

From the above description, it will be appreciated that I have provided an improved form of dispenser particularly adapted for dispensing oil from containers made of flexible material and which are normally not form sustaining in such a manner that not only is all of the oil removed from the container but the attendant dispensing the same will not be required to attempt to dispense the oil from a flexible container. It will also be appreciated that many changes and modifications in mechanical construction may be made without in any way departing from the spirit or scope of the invention. For example, a

plurality of spikes or prongs may be provided in the container for dispensing as illustrated in Figs. 4 to 7 inclusive, without in any way departing from either the spirit or scope of the invention. Similarly, the rollers may be made of any suitable material, such as rubber not affected by oil or other means and the shape of the fixed and movable bars provided in the modification, as shown in Figs. 1 to 3 inclusive. may be varied without in any way departing from the scope of my present invention. It is therefore to be understood that my invention is limited only by the scope of the appended claims which are to be broadly construed.

What I claim as new is:

1. In a dispenser for liquid packages having a container provided with a dispensing opening. means in said container for fracturing said package to open the same. and means for squeezing and collapsing the walls of said package as it is being withdrawn from said container comprising a fixed member and a member movable relative thereto between which said package is withdrawn, means for moving said movable member toward said fixed member to exert a squeezing force on said package. and means for destroying said package sufficiently to prevent its reuse.
