Application November 10, 1930 Serial No. 494,655
3 Claims. (Cl. 22065) This invention relates particularly to the containers for shipping paints, varnishes, lacquers, etc., by the manufacturer or wholesaler. Containers of that class customarily are returned by the customer to the manufacturer, wholesaler,
or owner, after the contents have been removed, and must then be thoroughly cleaned on the inside, at considerable-expense before being again filled and shipped.
The main object of this invention is to materially decrease the expense by avoiding the necessity of removing the paint, etc., which under the old practice adheres to the inside of the walls of the container, so as to prepare it for refilling, after its return to ihemanufacturer or wholesaler of the paints, etc.
v To this end I provide a suitable lining which is made of paper or other comparatively inexpensive material and so formed as to avoid the likelihood of accidental breaking or tearing, in such manner as to permit the contenis to run through and against the inside of the walls of the container, which under the present practice is usually a metal drum.
The lining is secured to the drum at the part immediately surrounding the bung opening, where the contents are to be discharged, and is also secured at the part immediately surrounding the vent which is'usually provided in the head or cover of the drum or at or near onelend of the drum or other container.
The objects of this invention areaccomplished by the method hereinafter described, and by the construction illustrated in the accompanying drawing, in which:
Figure 1 is a paper bag and cover, shown partly in section, and partly broken away.
Fig. 2 is a metal drum or shipping container.
and cover, partly in section, and partly. broken away, and showing the cover removed from the 'body of the drum.
Fig. 3 shows the container or drum with the cover altached by means of a clamp, the drum being shown in a position difiering from that of Fig. 2, so that the bung opening is at the side,
and showing also the bag or lining secured within the drum. In this figure the parts are also shown in section and partly broken away.
Fig. 4 is an enlarged view of the upper left-hand 5 0 part of Fig. 3.
Fig. 5 is a view partly broken away and partly in section, of a bag or lining with the cover in the closed position, and in which the body of the lining is made with a seam or overlap on the side,
5 formed with the overlapping edges of the macloses the bung opening and vent, and returns terial pasted together, as is common in the manufacture of paper bags.
In the prac.ice of this invention, the body 1 of the lining maybe made of paper or other comparatively cheap material, either in one piece as shown in'Fig. 1 or with an overlap on the side,
as shown at 2 in Fig. 5, or may be made in any other suitable manner so that the bag or lining will fit snugly against the walls of the container, and thus avoid liklihood of tearing after being filled with the paint or other material to be shipped.
Before placing the bag within the container 2, glue or other suitable adhesive material is applied at 3 around the bung opening 4, and is also applied at 5, around the vent opening 6. The bag or lining is flanged at 'lso that its flange 7 will lie over the upper edge or flange 8 of the tank. Before the lining is inserted, the bung opening 4 is closed by a plug or suitable closure device 11, and the vent opening 6 is closed as by a plug or suitable closure device 12. The lining is then pressed against the adhesive surrounding the bung opening 4 so as to form a closure around the bung, and so as to permit the paper to be subsequently punctured at the bung, and avoid any of the contents running in between the lining and the wall of the drum at any place around the bung.
The disk or cover 9 of the bag or lining is placed in position against the inside of the metal cover 10, and is pressed against the adhesive with which the vent opening has been surrounded at 5. This is done so that the lining may be punctured at the vent in like manner, as has been described in regard to the bung opening. The paint or other material to be shipped is then filled into the bag or lining. The drum cover 10 is placed in position upon the top of the drum so as to overlap the flange 7 of the bag and the flange 8 of the drum. The cover is then snugly secured upon the tank by means of a clamping ring 13-which is at first spread so as to be readily fitted over the flange 8 of the drum body. The ends of the ring are then drawn together by means of a screw-threaded bolt 14 seated in the lips 15 and 16 which are fixed on the ends of the clamping ring 13. The container is then ready for shipment.
' To remove the contents, the customer opens the bung holeor closure at 4 and also opens the vent or closure at '6, and punctures thelining at each of these places. After removing the contents at the bung opening 4, the customer then the container to the manufacturer, wholesaler, or owner, who then, after removing the cover and turning the container on its side in position with the bung opening upward, makes a cut or tear in the bag or lining, around the bung opening or otherwise loosens the main part of the body of the bag from the wall of the drum at 31, and then removes the body of the bag. The cover 9 of the bag or lining is likewise cut away or loosened from its attachment to the cover 10, at 5. Thus the only parts of the container that require cleaning are those immediately at and around the bung and vent closures.
The outlet closure as well as the vent-closure may be located at positions other than shown in the drawing and might both be in the cover of the container or suitably positioned in the body as is now done in a variety of ways in containers adapted for storage or shipment of liquid or semi-liquid materials.
Although but one embodiment of the invention has been herein shown and described, it will be understood that some of the details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
1. A shipping drum for paints and the like having a removable sealing cover, the drum body and said cover having a bung and a vent respectively, a-bag lining for said body and a disc lining for .said cover, said linings having their edges clamped together by said cover about the rim of said drum, said linings being adhesively secured to said body and cover immediately about said eeaoae contents, and adapted to seal against the admission of paint between the lining and drum when part of the lining spanning the bung and vent is ruptured. b
2. A shipping drum for paints and the like, one end of the drum having a removable sealing cover, a removable bung in the wall of 'the drum, a bag lining removable through the end of the drum, said bag lining covering the interior of the bung hole, said lining provided with means functionally related to it and the surrounding wall of the bung hole to seal against the admission of paint between the liner and drum when the disk-likeportion of the seal spanning the bung hole, is ruptured.
3. A receptacle comprising a rigid shell having an end-opening and a closure therefor, a wallopening and a closure therefor, in combination with a removable bag-like lining removable through said end-opening, the main body of which lies unattached against the shell-wall, the lining adjacent said wall-opening being adhesively secured to said shell surrounding said wallopening to seal against the admission of any part of the contents of the receptacle between the lining and shell when a portion of the lining spanning said wall-opening is ruptured.
