. l face at the upper part of the receptacle, so that when the punctured container is withdrawn, the
contained liquid will be stripped therefrom.
Such a device may be used to deliver lubricant to a receiver, such as the crankcase of an automobile, and is intended to effect the complete emptying of the container of its entire oil contents including that which would otherwise adhere to the inner walls of said container, or which would be slow in reaching the outlet of said container.
One object of the present invention is to provide a new and improved device of the general type referred to.
Another object is to provide a device of the 25 general type referred to, having means for guarding the puncturing member so as to prevent accidental hand contact therewith and resultant injury to the operator. Another object is to provide puncturing means so for forming a drain opening of large cross-sectional area closely adjacent to or contiguous with the bottom of the container, to insure a faster outflow of liquid from said container, and to prevent the forming of oil retaining pockets in the lower portion of the container.
Still another object is to provide new and improved means for supporting the puncturing member so that said member may be easily taken out of the receptacle for sharpening or replacement.
A further object is to provide a device of the general type referred to, which may be easily assembled or disassembled.
Various other objects, features and advantages of the invention will be apparent from the following particular description and from an inspection of the accompanying drawing. In the drawing- Fig. 1 shows a vertical section of one embodi- 5 ment of the present invention, with the container punctured and ready to be drawn out of the receptacle with accompanying stripping action,

Fig, 6 is a perspective view of a type of flexible container that may be used in conjunction with the present invention, said container being shown in connection with the puncturing member,
Fig. 7 is a section taken on the line 'l-l of Fig. 6, but showing thebag partially collapsed,
Fig. 8 is a section taken through the bottom seam of the container, on the line 8-8 of Fig. 6,
Fig. 9 is a perspective view of the collapsed punctured bag after it has been stripped of its' entire contents.
In Figs. 5-8 is shown a form of flexibly walled oil container l0 which may be used inconjunction with the present invention, and which is more fully disclosed and claimed in a copending application, but it must be understood that any other type of flexibly walled container may be used for the purpose of the present invention. In the form shown, the bag is made from thin flexible sheet material in strip form, which is progressively collapsed and sealed longitudinally at the edges and transversely at spaced points along the length thereof, and which is thentrans versely cut intermediate of the ends of the sealed portion to form the complete hermetically sealed 'collapsed bag Ill.
The bag I0 is formed primarily of impervious flexible sheet material which may be sealed by heat and pressure, or by the use of adhesives or solvents. For instance, it may be material sold under the name of Pliofilm, which is made from a chlorinated rubber compound, and which is thermoplastic and readily vulcanized or sealed at a temperature of approximately 115 C., so that overlapping sections thereof may be sealed together by the application of heat and pressure.
The bag I0 is formed of a sheet ll of Pliofilm or other material referred to, having its side sections l2 heat sealed to the sides of a narrower sheet of Pliofilm I3 along its entire length to form a tube. The sheet II is tucked inwardly from a the sides of the sheet l3 to form a pair-of infolds H on each side of the collapsed bag. These infolds H are narrow so that the inner fold edges of one pair of infolds do not abut or overlap the inner edges of the opposite pair of infolds, 55
Cemented or otherwise secured to the Pliofilm sheet l3 to form a laminated wall therewith, is a reenforcing sheet I! made of paper or other flexible sheet material which will not be iniuriously affected by-the application of sufficient heat and pressure to effect sealing, fusing or vulcanizing of the Pliofilm. In order that the comer of the bag l0 along. the side edges of the sheet I! be strong when in fully charged condition, said sheet it extends beyond the side edges of the Pliofilm sheet i3 to form marginal extensions l3, and portions of the side sections l2 of the Plioflhn sheet II project outwardly beyond the side edges of said sheet l3, and are directly glued or cemented at A to said marginal extensions. Such sealing by adhesive and byattachment of the sheet it directly to the paper sheet i5 at the corners, has a reenforcing effect which will compensate for any weakening resulting from heating and softening of the Pliofilm at the comers.
In the forming of the bag, the continuous tube in collapsed condition is sealed transversely thereacross over an area whichis then transversely severed, so that the portion of the sealed area on one side of the line of severance forms the bottom seal across the entire width of the bag l0 as shown in Fig. 8, while the portion of the sealed area on the other side of the line of severance forms the side seals 2| in the top of the next succeeding bag, the portion of said latter bag between said side seals 2i forming an opening through which the latter bag may be filled.
After the bag has been filled, the opening thereof is permanently sealed by heat-sealing together the facing Pliofilm linings of said opening. The sealing across the tube is eifected by heat and pressure so that all of the superposed layers of Pliofllm are autogenously bonded together and to the sheet l3. The bottom seal 20 will consist of two thicknesses of Pliofilm sealed together at the center, and seven thicknesses of Pliofilm sealed at the side edges.
Since the sealing across the tube is eflected by a single heat-sealing operation, non-uniformity in the number of overlapping Pliofllms across the width of the collapsed tube might, un-
der some circumstances, cause the overheating of the center portion of the tube whereby the overheated section of the Pliofilm sheet ll along said center portion might stick to the platen member forming part of the sealing apparatus. In order to avoid the liability of this happening, a paper sheet 22 may be cemented or otherwise secured tothe Pliofilm sheet I 1 across an area extending slightly beyond the inner edges of the side seals.
The two paper sheets I 5 and 22 on opposite sides of the container serve not only for the purpose referred to but may also serve to carry advertising or other printed notices.
The container of Fig. 6 has a capacity which is greater than the amount of oil stored therein so as to compensate for the change in volume of oil due to changes in the temperature thereof. The air from the head space above the liquid level is exhausted so that the opposite walls of the upper portion of the container may come together as shown in Fig. 6 to form a comparatively long "flap 23.
The containers asshown in Fig. 6 lend themselves to efilcient storage and transportation in trays of the multiple compartment type. If the compartments of these trays be of such size as but are spaced'a substantial distance from said to snugly receive one of said containers, the sediment or other foreign material collecting in the bottom corners of the compartment might, under some circumstances, puncture the container and cause leakage thereof. In order to avoid this possibility, the paper strip 22 extends beyond the cuter edges of the infolds l4, so that when the container is placedin a tray compartment with the paper strip 22 facing downwardly, the marginal extensions 24 of said strip 22 beyond said infolds will fold upwardly along the side walls formed by said infolds i4 and thereby protect the bottom corners of the bag from direct contact with foreign matter which may have collected in the corners of the tray compartment.
In the specific embodiment of the invention shown in Figs. 1-3, there is provided a receptacle which is so designed as to receive a suitable flexibly walled container in upright position. in the specific form shown, the receptacle comprises a tubular'sheli ll of rectangular cross-section having a front wall 32, a rear wall 33 and side walls 34. The bottom of the receptacle may be formed by a plate 35 connected to the tubular shell 3| by any suitable means, as for instance soldering, and having a'substantially horizontal section 31 spaced from the bottom of the tubular member 3|, and an oblique section 38 extending to the front wall 32. This oblique section 38 is provided with an opening 40 and has a discharge nozzle 4! connected thereto in communication with said opening. A flexible hose 42 may be connected to the nozzle 4i, and passes through the front wall 32, and its delivery end is adapted to be inserted in the inlet of a lubricant receiver to be filled. The end of said hose may be provided with a hook (not shown) for engaging a staple 43 connected to the front wall 32 so that said hose may be supported close to the receptacle in non-dripping position when not in use.
The bottom wall 'section 31 slants slightly downwardly towards the nozzle 4i so that the oil collected in the bottom of the receptacle will flow towards said nozzle.
Extending between the side walls 34 f the receptacle and spaced inwardly from the rear wall 33 is a plate 45 servingto form the rear wall of the container receiving chamber 46 of the receptacle and forming with said wall 33 a compartment 41 for receiving at least a portion of the stripper operating mechanism. This plate 45 is detachably secured within the shell 3| in any suitable manner. For instance it may be provided with a pair of side flanges 48 extending along the side walls 34 and having notches 50 at their bottoms for engaging buttons or studs 5| connected to said side walls 34 to hold said plate 45 against lateral movement. At the upper ends these flanges 48 may be connected to the side walls 34 by removable fastening means such as bolts 52. V
The bottom of the plate 45 is provided with an opening 53 to afford free communication between the chamber 45 and the compartment 41, thereby preventing oil from being retained in said latter compartment during container discharging operations.
The puncturing member includes a knife disposed within the lower portion of the container receiving chamber 46 of the receptacle and adjacent to the outlet opening 40. As an important feature of the present invention, this knife is constructed to form a knockout flap 54 in the bottom of the container so as to form a drain opening of substantialarea. For that purpose, this knife is of substantially U-shaped cross-section and is adapted to form a correspondingly shaped slit in the bottom of the con"- tainer. In the specific form shown, this crosssection is somewhat semi-cylindrical and the knife 55 is provided with a pair of cutting edges 56 converging towards a sharp piercing point 51. The bottoms 58 of the cutting edges 56 extend approximately along. the medial plane .of the container receiving chamber 46 of the receptacle so that the knife 55 as it pierces the bottom of the container as shown in Fig. 6, makes a U-shaped slit 60 down to the bottom seam of the container as shown in Fig. 9. This slit 60 defines a drain opening which is of substantial area and which extends to the extreme bottom of the container, so that no liquid retaining pockets are formed in the bottomof the container on opposite sides of said drain opening.
As an important feature of the present invention, the knife 55 is supported on the detachable wall 45 so that said knife can be taken out of the receptacle for sharpening or replacement. For that purpose there is provided a pair of rods 62 soldered or otherwise connected at one end tothe lower section of the knife 55, and having the other ends passing through the wall 45 and forming angular extensions 63 soldered or otherwise connected to said wall. The bottom of the knife 55 rests on the bottom wall 36 of the receptacle to support said knife against the pressure of the bag ill during puncturing operation.
The stripping device comprises a pair of vertically spaced platen members in the formof rods 65 presenting platen surfaces for cooperation with a rotatable pressure roller 66. This pressure roller 66 is normally urged into pressure applying position with respect to the platen rods 65 as shown in Fig. 1, and is angularly movable into inoperative positionshown dotted in Fig. 1 to permit the container ID to be insertedbetween said pressure roller 66 and said platen rods 65. For that purpose, the pressure roller 66 is rotatably carried by a pair of similar lever arms 61 extending closely adjacent to the side walls 34 and pivoted respectively to said side walls at 68. In order to angularly move the lever arms 61 about their pivotal connection 66, each of said arms has an extension arm 10 passing through an opening in the plate 45 and having an elongated slot 1i through which passes the end of a rod 12. Fixed to the central portion of said rod 12 is one end of a lever arm 13, the other end being fixed to a rod 14 journaled in suitable bearings connected to the flanges 48 of the detachable wall plate 45.
The lever 13 is actuated by an operating mechanism in the form of a thumbpiece 16 extending through a slot 11 in the rear wall 33. The de pression of the thumbpiece 16 in a clockwise directionas shown in Fig. 1 into the dotted position shown, causes the, rotation of the rod 14 and the corresponding angular movement of the lever arm 13 so that the lever arm 61 carrying the pressure roller 66 is swung in a counterclockwise direction.
In order to normally maintain the pressure roller 66 in the pressure applying position shown in Fig. 1, there is provided a torsion spring 16 encircling the rod 14 and having one end 19 curved downwardly as shown in Fig. 1 andengaging the detachable wall 45 so that said rod 14 is urged in a counterclockwise direction. Under the action of the torsion spring 16, the stripping device will normally be in the position shown in Fig. 1 and will be locked, so that the movement of the pressure roller 66 away from the platen rods 65 can be effected only by the upwardly towards the receptacle, so that the thumbpiece 16 is conveniently accessible. for operation by the thumb of the hand grasping said handle.
In order to provide resilient yield between the pressure roller 66 and the platen rollers 65 dur ing stripping of the container so that said members may permit the extra thickness of the container, such as that along the bottom seam, to pass therebetween, the platen members 65 are welded or otherwise connected to a pair of spring plates 64 connected at their lower ends to the detachable wall plate 45.
By means of the construction so far described, the entire stripping mechanism and the knife 55 are supported solely on the detachable plate 45 and may be removed from the receptacle as a unit with said plate.
In order that the pressure roller 66 in inoperative position shown in dotted lines in Fig. 1 and the platen members 65 do not interfere with the dropping of a container in the chamber 46, the upper section 86 of the wall 32 and the. upper section 81 of the detachable wall plate 45 are flared upwardly to form recesses to receive these members as shown.
As a feature of the present invention, means are provided for rendering the knife 55 inaccessible for container puncturing operation while the receptacle is not in use, so as to prevent the hand of the operator from coming in contact with said knife and being accidentally injured. In the specific form shown in Fig. 1, this means is in the form of a guard 90 which, when the receptacle is not in use, extends over the open end of the receptacle to prevent a. hand from being inserted in the interior of the receptacle. This guard is formed of a wire having end extensions 9| soldered or otherwise connectedto the lever arms 61 so that said guard 90 is actuated in unison with said lever arms. and having an intermediate U-shaped section 92 so that when this wire guard is in the dotted position shown in Fig. 1, said U-shaped section 92 clears the nozzle retainer 43.
In the construction shown in Fig. 5, the guard serves not only to prevent the insertion of the hand into the receptacle but also serves as a cover for the receptacle so that rain or other foreign matter does not find its way into said receptacle while it is not in use. In this form the guard is in the form of a coverplate 94 pivotally connected to the upper end of the front wall 32 of the receptacle by a hinge 93 and having a sloping section 95 presenting a cam surface which is engaged by the pressure roller 66 as it is moved in a counterclockwise direction. This riding of the pressure roller along the cam section 95 causes the cover plate 94 to swing open ina counterclockwise direction about the hinge 93 so that the upper end of the receptacle is uncovered to permit a container to be dropped therein.
In order to limit the open position of the cover plate 94, said plate has an extension 91 on its hinge section, which engages the oblique wall section 86 of the receptacle in limiting position,
to prevent further counterclockwise rotation of said cover plate 94. In this limiting position the cover plate 94 will be urged into the closed position shown in Fig. 5 by its own weight.
When fllling a crankcase or any other lubricant receiver, it is quite often necessary to empty a number of containers into the. receptacle. order to provide a suitable and conveniently located receptacle for the containers as they 'are emptied, a plate I00 is connected to the bottom of one of the side walls 34 of the receptacle and is shaped to form a receptacle i0l therewith. Connected to this plate I00 and to said last mentioned side wall 34 is a wire frame I02 forming with the receptacle IN a basket. The containers as they are emptied, are dropped into this basket and held therein until the operation of filling the lubricant receiver is completed.
In the operation of the device, in order to move the guard 90 of the construction of Fig. 1, or the guard 94 of the construction of Fig. 5, into position to permit dropping of a container into the receptacle, the thumbpiece I6 is depressed. This operation causes the pressure roller 66 to move into the dotted position shown, and said guards to move away from the upper end of the receptacle- While in this position, the container I0 is dropped into the chamber 48 and the piercing knife 55 forms a substantially semi-circular opening closely adjacent to the bottom seam of the bag as shown in Fig. 9. The pressure on the thumbpiece I8 is then released and the pressure roller'68, under the action of the torsion spring 18, is moved into the position shown in Figs. 1-5.
The receptacle is of such height with respect to the container that when the container I0 is in said receptacle, a substantial portion of the container flap 23 will extend or may be held so that it extends above the platen members 65, so that when the pressure roller 68 returns into pressure applying position shown in Figs. 1 and 5, the upper portion of the container flap 23 will be, caught between said pressure roller and said platen members. The upper portion of the container flap 23 extending above the platen mem-- bers 65 is grasped by the flngers and the container drawn upwardly. The combined drawing action on the container and the pressure action of the roller 86 causes the stripping of the container and the forcing out of its entire contents, to
leave the stripped container in approximately,
the flattened or collapsed condition shown in Fig. 9.
In Fig. 1 the parts are shown in approximately the position which they would occupy after the bottom of the bag has been punctured, a portion of the contents has drained out, and the upper portion of the bag has partially collapsed, but before the stripping action begins. At this period in the operation, some-of the oil may have drained around into the compartment 41 and more will flow into that compartment as the bag is pulled up through the stripping apparatus, but to simplify the illustration no oil is shown in that compartment.
Obviously various changes may be made in the details of construction and the relative positioning of the parts without departing from the scope of my invention.
