3 Claims.

This invention relates to improvements in the art of packaging and dispensing fluent commodities.

A general object of the present invention is 5 to provide an improved method of and means for packaging a fluent commodity in a sealed container and in subsequently providinga discharge opening in the container and manipulating the container in a manner so as to forcibly discharge some of the commodity directly therefrom through the opening in'the form of a spray or stream.

A further object of the invention is to provide a method of and means for packaging a fluent commodity in a telescopic containerand then subsequently so operating the container, after an opening has been formed therein, to cause some of the commodity to be pumped therefrom, the original container serving as the impelling means.

A further object of the invention is to provide a container, generally of paper board construction, which may be readily initially filled or loaded with a fluent commodity and thereafter be subjected to a certain manipulation so as to forcibly eject -material directly from the container in the form of a spray or stream, the container'being of a character so as to preclude its being refilled, and furthermore being very inexpensive so that it may be discarded after the contents have been discharged therefrom.

As a more specific aspect of the invention, itis contemplated that the present method and container per se are especially adaptable for use in connection with the vending of oil. Recently, oil companies have found it very desirable to vend oil in containers formed of paper board. It is desirable that the paper board container for this purpose have metallic ends, one of which is opened or mutilated for dispensing purposes. Paper board containers of this general type are very advantageous because they are non-refillable and therefore cannot be re-used with a substitute or inferior commodity, are easily disposed of, are cheap, and arelight. The major objections, heretofore, to this type of an oil container reside in the fact that oil is very diflicult to pack and store because it has great seeping and leaking tendencies, and in this general class of containers, when used for oil, the walls of the con- 55 body. In addition, due to the fact that the ends tainers have been marred and rendered unsightly PATENT OFFICE of the bodyof these containers are closed by metal caps which are crimped or-clamped intoplace, the packer must of necessity have special cap applying machinery, which is a draw-back and disadvantage. 1

With reference to the'present invention, it is a more specific object to provide a paper board container especially adapted for the packaging of oil, and overcoming the above objections by virtue of constructionalfeatures which eliminate 0 the possibility of oil leakage or seepage, the container furthermore being of'such a character that the manufacturerv can originally apply the metal caps to the ends ofthe body portions, and the packer is only required to fill the con- 15 tainer and to seal it or close it ina very convenient manner without the necessity of having special equipment or machinery for this purpose.

A further object of the invention is to provide a paper board containerespecially adapted for 20 the packaging of oil, which meets all of the requirements as to being light, durable, nonrefillable, and inexpensive. r 7

A further object of the invention is to provide a paper board container of the character de- 25 scribed, which after being opened for dispensing purposes may be used in the nature of a pump so as to forcibly eject oil therefrom whereby the contents of the container may be easily and rapidly exhausted.

.A further object of the invention is to provide a paper board lubricant container which. may have interchangeable fittings applied to the discharge end. thereof to adapt the container to the forceful dispensing of various types of lubricant directly into the various portions of a motor vehicle, such as the crank case, transmission, o'r the differential. I

A further object of the invention is to provide a method of and means for packaging and dispensing a fluent commodity which is very simple, which is inexpensive and expeditious, and which is well adapted for the purposes set forth.

With the above and. other objects in view, the invention consists of the improved method of 45 and means for packaging and dispensing fluent commodities, and its parts, combinations, and steps, as set forth in the claims and all equivalents thereof. v r 1 In the accompanying drawings in which the same reference characters indicate the same parts in 'all of the views:

' Fig. 10 is a vertical sectional view of thecontainer of Fig. 8,'only showing the telescopic move} mentof the container'sections toj effect pump action for the discharge of the contents Referring now more particularly to the form of the invention shown in Figs. 1 to 6 inclu sive, it

will appear that the improved container comprises a pair of complementary telescopic sections including an outer section l5 and an inner section [6; both of which are of cylindrical formation with the cylindrical bodyportionsof the same being formed of plied paper board or other suitable fibrous material. The outerend of the scctionlS is sealed and closed by means of a dished metallic cap I! best shown in' Fig s.,2 and 4. The end wall portion of the tubular section IE to which thecap I1 is applied, has crimped there-about a .U-shapedband or collar I. ii,,and when the cap I! is applied to said end portion of the body section IS, the peripheral. flange IQ of said cap is bent tightly about and into engage; ment with the collar l8, tightly clamping and embracing the end portion ofthesection I5. If'desired, a soldered connection may be effected between contacting portions of the collar 18 and the cap flange l9. r

The outer surface of the cylindrical body of the. inner container section l6 has a coating thereon as indicated at 2!] in Fig. 4. Said coating is of a character so as to render the wall of the member I6 impervious. .The outermost end of the container section I6 is surrounded by a fibrousmaterial collar 2| which is positioned relative to the end of the body section l6 so as to extend somewhat beyond the said end and thereby provide an internal annular shoulder. The end portion of the body section It under consideration is tightly embraced by a U-shaped metallic element 22, and the inwardly oiTset face of a. metallic end cap 23 seats firmly against'said embracing element 22 and has its peripheral flange 24 bent over and clinched to the projecting end portion'of the collar 2| so as to tightly embrace said projecting end portion of the collar. It will thus be noted that said end of the inner telescopic section 16 is thus closed by the metallic cap 23 which is seated on the metal enshoulder of the collar 2|.

cased shoulder, and the union can be additionally strengthened by a soldered joint, if desired.

The form of container under consideration is especially suited for the packaging and dispens packer merely has to separate the sections I5 and IBand fill the inner section 16 with the oil or othertfluent commodity. Thereafter the container is closed by moving the section 15 onto the section I5 and sliding it lengthwise thereof in a telescopic manner until the uncapped end of the section I 5 contacts the inner peripheral It should also be observed that the container sections 15 and lfi are "so proportionedthat when the container is thus closed, 'theinnerinost end of thesecnosl6 will abut tightly against the inset wall of the endfcap l uin thegmanner shown in' Fig.12. When the container is' thus closed; it 'may be sealed in this condition bythe application of a sealingmedium to theQcreVice'orjointbetween the open end of the section j 5 and the inner periphery of the collar 2'l ,-"a s 'indica ted at 25 in Fig. 2l It is also ob- "viou's that the container joint may be sealed or closed byany other convenient means such {as tape or the like;

"geous 'for the holding and storing of a commodity such as "OiL E BBQaUSQ of the two-sectional construction of the container there are a multiplicity of plies throughwhich material would have to seep i'fjleakage through the major wall portion should occur, andthe characteristicsof the walls and hee mber of P ies forming l g amen e eludes this possibility. In addition if the tubular Wa a rme ltwi i l n a seams e outermost section covers 7 and protects .the seam of the inner section. In addition to this the innermost'section has the coating or impregnation 20 which guards. against leakage or seepage, Leakage. or seepage at the ends of .the container is protected against by virtue of the constructions of said ends and the manner in which the end caps I'l and 23 are'applied. The cap i1. is clinched aboutv the metallic element I8 and the end 'of' the body member J5 is tightly embraced and clamped therein, and'inrclosed condition the end of the inner section l6 tightly abuts against the capll and element I8 and forms agasket or washer. The same is.1ikewise true-of theother endof the container. In this instance the metal cap. 23 is appliedto the. peripheral portionof the collar 2| but. it seats on and abuts against the metallic'element 22 which in turn clinches the end of the inner section. |6.. i

so instruct the attendant, and the proper se 23 of the 'container'will be ruptured or cut out to provide an opening 26 therein, as in Fig. 3,

and the seal orsecuring means between the collar 2i and section 15 will be broken. A special appliance 2'7 (see Fig. 5) with which the attendant is provided, will then be forced over the ruptured end of the section l6, and said appliance 21 includes a cupped portion 28 with overhanging sides which tightly and frictionally embraces outer portions of the collar 2|. The outer wall of the cupped member 28 has an opening 29 therein from which extends a section of flexible tubing 30 which carries a nozzle or spout 3| at its outermost end. A funnel structure 32 may be incorporated within the cupped member 28 with its reduced end registering with the opening 29 and the inner end of the flexible tubing 30. V

When the appliance 21 is thus positioned on the proper end of the container and the seal is broken, the end of the tubing 30 is introduced.

into the crank case inlet opening of the vehicle and then the operator holds the container with the section IS in one hand and the other section l5 in the other hand and reciprocates said sections back and forth telescopically in the manner of a pump and thereby forcibly and quickly ejects all of the contents of the container into the crank case via the tubular connection 30. After the container has been thus emptied, the appliance 21 is removed so as to be subsequently used with other containers, but the emptied container is then discarded and may be readily destroyed. It cannot be refilled or re-used because the metallic end thereof has been ruptured and opened for dispensing purposes.

In Fig. 6 a slightly modified form of appliance 21 is illustrated in its application to the discharge end of the container. This appliance 21' is especially adapted for use in connection with introducing the contents of the container into the differential or a like portion of a vehicle. The appliance 2'! has a cupped portion 28' which is frictionally fit onto and over the opened end portion of the container, as shown in Fig. 6. The fiat end wall of the appliance 21' has a central discharge opening therein, from which a tubular stub 30' projects outwardly. The outer end of the stub 30' is externally threaded as at 32 to receive the internally threaded inner end of a hook shaped discharge nozzle 3|. In use said nozzle 3| is introduced into the opening into which lubricant is to be forced, and the container is reciprocated back and forth telescopically to pump out the contents through the stub 30' and nozzle 3|. If desired the appliance 21' may be equipped with an air vent 33 which will be located over the rupture 26 in the container end. The orifice 34 in said vent 33 is normally closed by a ball valve 35 to prevent the fio'w of lubricant therethrough, but said ball valve can move away from the orifice 34 to admit air to facilitate the pumping operations.

A modified form of container is shown in Figs. '7 to 10 inclusive. This form of container is especially adapted for the packaging of fluent commodities of a granular nature wherein'the concern regarding leakage and seepage is not acute. Said form of container comprises an outer cylindrical section l5 closed at its outer end by a metallic cap I1 and an inner cylindrical section l6 having its outer end portion surrounded by a collar 2|, the outer end of which has clinched thereto a metallic end cap 23 whose inner peripheral portion seats against the shoulder formed at the end of thetubular section IS. The sections l5'fand l6 are'formed of paper board or similar fibrous material, and the cap 23', which forms the dischargeend of the container, is provided with an outer circle of relatively small discharge orifices 36 and a central orifice 37 through which air may beadmitted.

In use the discharge end 23 0f the inner-section I6 is covered by a temporary and removable cap 38 (see Fig. 8). The section I6 is then filled with the fluent commodity through its openend, and the package is next closed by inserting the section l5 onto and over the section l6 until the condition shown in Fig. 8 isattained. The joint or crevice betweentheend of the section I5 and the end of the collar 2| may be sealed and closed by a strip of tape 39, or other suitable sealing medium applied thereto as shown.

The package as thus filled and sealed is in condition for vending, and it is especially suited for holding commodities such as lawn seed, pulverized fertilizer, sand, insecticide, disinfectant or the like, or in fact any powdered or granular commodity which it is desirable to spread over a given area by means of a spraying operation. In use the sealing medium 39 is removed as is the cap 38 which temporarily closes the discharge apertures 36, and then the container is operated in the manner of a'pump to discharge the contents in spray form, in the manner shown in Fig. 7;

From the foregoing description it will be seen that with the present invention a suitable commodity can be originally packed in the container in a very convenient and expeditious manner without the necessity of special tools, equipment or appliances. When the commodity is thus packaged it is presented to the consumer in an attractive sealed manner, and the package is of such a nature that re-use or refilling of the same With an inferioror substitute commodity is pre- .While the particular embodiments of the invention have been set forth for the purpose of description, it is not intended that they invention be limited precisely thereto, and all changes and modifications as are withinthe scope of the annexed claims are contemplated.
