6Claims.

This invention relates to improvements in containers.

The objects of this invention are:

First, to provide a container formed mainlyof fibrous material which is suitable for use in the dispensing of oils and greases.

Second, to provide a leak-proof container formed mainly of fibrous material in which the imperfections of material, such as "pin-holes" common in paper and materials formed of fiber and resulting from manufacturing conditions, seemingly impossible to eradicate, are rendered unimportant.

Third, to provide a container adapted for the uses stated and having the advantages stated which may be produced economically and on a large scale.

Objects pertaining to details and economies of the invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of our invention is clearly illustrated in the accompanying drawing in which:

Fig. 1 is a perspective view of a sealed container embodying the features of our invention.

Fig. 2 is a fragmentary longitudinal section.

Fig. 3 is an enlarged detail section on line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail section on a line corresponding to line 4 4 of Fig. 1.

Fig. 5 is an enlarged detail section taken on a line corresponding to line 5-5 of Fig. 1.

Fig. 6 is an inverted view.

Our container is especially designed for use in dispensing oils such as lubricating oils and greases such as lubricating greases, lard and the like. It is now quite common practice to dispense lubricating oils from original containers as a means of insuring to the customer that he is receiving the kind and quality of lubricant desired. The containers are destroyed or rendered useless in the dispensing so it is highly desirable to provide a container which may be economically produced and at the same time is effective in retaining oils and greases which penetrate the ordinary fibrous containers.

In the accompanying drawing we have illustrated an embodiment of our invention as adapted for the dispensing of lubricant. Our container comprises a tubular side wall I of fibrous material preferably formed on a spiral wind tube forming machine. The details of the wall structure are not illustrated as spiral wind tube forming machines are well known in the art. The side wall, however, should be continuous from end to end.

We provide a lining consisting of

superimposed layers

2 and 3 of grease-proof paper, these being adhesively secured together throughout by an adhesive conventionally indicated at 4. The multi-ply lining is adhesively secured throughout by a layer of glue indicated at 5. We have found that certain dextrin glues are satisfactory for this purpose.

The lining is preferably formed by spirally winding the lining layers together with their joints overlapping as indicated at 6, Fig. 4. The lining may be applied as the side wall is formed in the event the side wall is formed on a tube machine. The lining is continuous from end to end of the side wall and by forming it of multiply paper any pin-holes or slight, fractures which commonly'occur in the manufacture of paper are sealed, and the likelihood of the pin-holes or slight fractures registering is extremely remote. Should such a thing occur the double layer of adhesive seals the same.

In the embodiment illustrated the container is provided with a tin cover 1 having a peripheral flange 8 seamed and clamped over the upper edge of the container side wall, this being commonly? applied by machinery, and the reverseiy turned outer portion 9 of the cover is clamped upon the wall with its edge i0 slightly embedded therein. This retains the cover for handling and also provides an effective seal, the flange of thecover being in compressing sealing engagement with the wall.

The other end of the container is closed by an inner end member ll of fibrous material having a downturned flange i2 telescoped within the side wall member. This inner end member is provided with a lining consisting of superimposed layers i3 and ll of grease-proof material adhesively secured together throughout as indicated at |5 and secured to the lining as indicated at i6. These inner end member linings extend over the flange i2 and they are adhesively secured to the wall lining at H. The end i8 of the side wall member is folded inwardly upon the inner side of the flange I2 and adhesively secured thereto at i9. The outer disk-like end member 20 is forced into this inturned portion l8 of the side wall member so that its edges are in clamping engagement therewith as indicated at 2| with the outer end member in supporting engagement with the inner end member. The outer end member is preferably of stock corresponding to that of the side walls and as indicated may, with advantage, be slightly thicker than the side wall stock.

With this arrangement of parts the joint between the side walls and the end members is effectively sealed so that liquid or oil cannot escape therethrough. One of the advantages of our invention is that the arrangement of parts permits production of the container at high speed or in large quantities with uniform results and with little likelihood of the containers leaking or permitting the escape of oils or greases.

In the embodiment illustrated, in which the top of the container is formed of tin, so that it may be pierced by the dispensing spout now quite commonly used in the dispensing of lubricant by service stations, we preferably provide the outer end member with a vent break-out portion 22 which is partially severed by an annular series of slits or perforations 23 so that, after the dispensing spout has been inserted in the turn cover.

I and the container inverted or in discharging position, the knock-out vent can be easily knocked out or broken to permit the free entranceof air. This also has the advantage of preventing re-use of the container, which is one desired feature in the dispending of fluids, lubricants for example.

We have illustrated and described our invention in an embodiment which we have found very satisfactory. We have not attempted to show various adaptations and modifications in structural detail which we contemplate as we believe this disclosure will enable those skilled in the art to embody or'adapt our invention as may be desired.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:
