PAPER-BODY can on REGEPTACLE.
Patented May 16, 1911.
Application filed J u 1 y 5, 1907. Serial No. 382,186.
To all when"; it may concern:
Be it known that I, FRANKLIN RUDOLPH,
a citizen of the United States, residing in .Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Paper-Body Cans or Receptacles, of'which the following is a specification.
I closed or sealed, and in which the body of the package requires to be stifl, strong and rigid against collapse, fle'xure or breakage, and further to provide for the application to the paper body of such can or receptacle of a bail when the receptacle is of such size as to require a bail for convenience of handlingl My invention consists in the means I employ to practically accomplish this object or result as herein shown and described and more particularly set forth in the claims.
In the accompanying drawing forming a part of this specification, Figure 1 is a central vertical sect-ion of a paper body can or receptacle embodying my invention Fig. 2 is a cross section on line 2-2 of Fig. 1. Fig. 3 is an enlarged detail section showing the construction of the paper body and Fig. l is a detail elevation of a portion of the body showing the same before the application of the bail ear thereto. Fig. 5 is a detail sectional view of the bail ear before it is clenched upon the body. Fig. 6 is a diagrammatic view illustrating the method of applying the japanning material to the paper web before it is wound layer upon layer to form the body of the receptacle. Fig. 7 is a central vertical sectional view illustrating a modification. Fig. 8 is an elevation illustrating a further modification.
In the drawing, A represents the paper body of the vessel, the same being of cylindrical or other form in cross section, and composedof straight or spirally wound coils a of paper Wrapped tightly upon each other and impregnated with a baking varnish,
lacquer or japanning material C which hardens upon baking and becomes impervious.
If the paperbody A of the receptacle is composed of paper or strawboard which is somewhat readily absorbent of the japanning material after the paper body of thereceptacle is formed by winding and gluing or cementing the successive layers of the paper together, the paper body is then immersed in the liquid'baking varnish, lacquer or japanning material or coated therewith on one or both. sides, and then subjected to a suitable baking temperature ordinarily from 215 to 500 degrees Fahrenheit for a period of from thirty minutes or such matter to three or four hours or more as may be required according to the kind of j apanning material employed and the use for which the vessel is intended. This operation renders the body impervious to liquids and acids and extremely hard, stiff and rigid, so that it will efl'ectually resist collapse, flexure. or
breakage in any ordinary usage to which the.
can orreceptacle may be subjected. If the paper body A- of the receptacle s composed of paper of such character as not to be readily absorbent of the baking var- I nish, lacquer or japanning material, instead of immersing in after it is formed, I prefer to immerse or otherwise apply to the web or layer of paper before it is wound or coiledlayer upon layer into the receptacle-body the liquid japanning material; this being in Fig. 6 of the drawing, by passing the web of papers through or in contact with the liquid baking varnish, lacquer orjapanning material. In this Way the japanning materialwill also serve to closely and intimately cement and unite all the layers of the body together into one solid homogeneous structure, the japanning material thus lmpregnating the paper body through and through or from inside to outside. After the paper body is thus formed, it is preferably immersed as an entirety in the liquid japanning material before the baking step or op;- eration so as to insure a smooth, continuous glossy japan coating upon the inside and outside of the body and including the extreme end surfaces thereof.
B represents the sheet metal bottom .head of the can or receptacle and D the sheet metal annular top head thereof. The hotthe liquid the paper body done as illustrated a liquid tight end of the tom head B is countersunk and has a countersink wall 6 fitting within the lower end of the paper body and a seaming flange b folded over around and against the lower paper body so as to tightly and snugly clamp the same between the inside fitting countersink wall I) and the curled edge or fold b of the seaming flange b so as to form a liquid tight joint or seam between the sheet metal bottom head and the body, the exterior japan coating 0 at the extreme end of the body and at the peripheral surface of the body at the end thereof serving to give a smooth surface and as a packing for the folded seam or joint to' make the same liquid tight and to protect the paper body from entrance or absorption of liquid at the end of the body between the separate layers composing it.
The annular top head D has a countersink Wall d fitting within the upper end of the body and a seaming flange d which is curled, rolled or folded over and against the extreme upper end of the body so as to tightly embrace the same between the inside fitting countersink wall 03 and the curled edge or fold d of the seaming flange d. The annular top head D also has a depending friction seal wall 0Z surrounding the opening D therein.
F is the friction cap or cover closing the opening in the top head D, the same having a peripheral pry-ofl rim f furnished with a fold f and a depending friction seal wall f tightly and snugly fitting the cooperating friction seal Wall 03 oflthe annular top D and forming a liquid tight closure therewith.
The japanned paper body A is provided with bail ear openings A therein to receive the bail ears G. These bail ear openings A are formed in the paper body A, preferably before the said immersion in the apanning material and before the baking operation so that the edge Walls of these bail ear openings will be covered and protected by the japanning material and thus prevent liquid being absorbed between the layers of the paper body at the bail ear openings and also to aid in securing joint between the bail ears and the paper body.
he bail ears G each comprise an inner closure shell g having a clenching wall 9 and a flange or rim g and an outer shell 9 having an eye to receive the hook h of the bail H. The closure shell 9 of the bail ear fits inside the paper body and its annular clenching flange or boss projects through the bail ear opening in the body with its marginal flange or rim snugly fitting and conforming in shape to the surroundlng wall of the paper body which it engages. Then, the outer shell 9 being applied, the annular clenching flange or Wall 9 is clenched or body is subjected to its final folded down over the rim 99 01, the shell 9 as il'lustrated in Fig.51, of thefdrawing so as to form a flange or fold 9 which, 1n connection with the fiangeor rim 9?. snugly clamps and embraces the wall of the paper body surrounding the bail ear opening therein, thus effecting a liquid tight closure. The japan coating in connection with the slight elasticity thereof and of the paper body embraced between the clenching flanges of the bail ear readily produces a liquid tight joint between the bail ear and the paper body. At the same time, the japan impregnated and baked pa er body is of such extreme hardness, sti ness, firmness, strength and rigidity that though the package may be six, eight,-ten or and height, and filled with comparatively heavy material, such as syrup, cereals or the like, it may be lifted and handled by the bail without any danger ofvtearing or destroying the more inches in diameter the attachment of the bail ears thereto or destroying the tightness of the joint between the bail ears and the paper body.
My improved japan impregnated and baked sesses such firmness, stiffness and rigidity in its paper body that the friction caps or covers' may be seated or forced into the annular tops after the receptacle is filled with the necessary pressure to produce a liquid tight closure without danger of the closing pressure collapsing, cracking, breaking or injuring the body or tending to fracture, weaken or loosen the union between the annular top D and the upper end of the, paper body A which is embraced between the annular seaming flange and the annular countersink wall of said top.
In the modification illustrated in Fig. 7 the bail ears are omitted.
In the modification illustrated in Fig. 8, the paper body is represented as being made of spirally wound paper straw or other board. In this modified construction, the paper or strawboard is wound a long continuous cylinder which is then cut into suitable lengths for separate can bodies, which are then dipped or immersed in the liquid japanning material and then baked.
he japanning material C may be composed of any suitable baking varnish or lacquer mixed with linseed oil or its equivalent and cut with benzin or turpentine or other equivalent and with any desired coloring matter added. By japan or japanning material in the claims, I mean to include any suitable baking varnish, japan or lacquer which, when mixed with linseed oil or its equivalent, dries and hardens when subjected to heat or baking.
Notwithstanding the baking operation to which the japan coated or impregnated paper body is subjected and the high degree spirally into of heat and long time which may be employed if desired in this operation, owing to the elasticity which the linseed oil or other equivalent vegetable oil imparts to the japan material and causes it to retain after baking, I find, in practice, that the operation of double seamingjhe top and bottom sheet metal heads on the japan coated vapor body does not break, crack or injure 'the japan coating, so that liquid tight joints are readily produced by seaming or crimping the metal heads on the japan coated paper or fibrous body.
I claim: 1
1. A receptacle having metallic heads and a paper body composed of a plurality of successive layers of paper coiled one upon another and impregnated through and through and coated with hard baked japanning material and rendered strong, stiff, rigid and impervious to liquids thereby, the
baked japanning material impregnating and uniting the successive layers of the paper body and forming an external elastic coatmg for the outer surfaces of said body and adapting the same to form a tight secure joint with ,a metallic head, substantially as specified.
2. Ina receptacle, a paper body composed of layers of paper impregnated through and through with japannln wmaterial and hardened by baking, the baked japanning mate-.
rial impregnating and uniting the successive layers of the paper body and forming an external elasticcoating for the outer surfaces of said body and adapting the same to form fittinfi in and closing said openings and having anges embracmg the paper body and forming tight joints therewith, the baked j apanning material impregnating and uniting the successive layers of the paper body and forming an external elastic coating for the outer surfaces of said body and adapting the same to form a tight secure joint with a metallic head, substantially as specified.
