Application May 29, 1939, Serial No. 276,379
2 Claims. (01. 220-97) The present invention generally to cans. More particularly the invention relates to that type of can which is especially designed for the packaging and preservation of food.
t is the main and primary object of the present invention so to construct cans of this type that the same readily may be packed for ship ment, and actually shipped in transportation to their points of use, at a greatly reduced cost to the purchaser or user. Thus, the cans may be placed in the hands of the user, even though the latter may be located at distant points, at figures that are relatively low, but greatly 'reduced as compared with the cost of the cans under former practices.
To the accomplishment of the foregoing ends, the present invention contemplates the provision of an improved form of can possessing generally a conical shape and other features of structure, whereby to enable the same to be nested with like or similar cans, and by which the consumer may obtain the same at the most economical price. At the present, fruit canning industries located far from industrial centers are compelled to choose between two courses, both of which are disadvantageous to them. Either they must pay a very high freight rate on madeup cans, which freight to distant points may amount to as high as 100% of the value of the original cans; or, to save such heavy freight rates, they must install expensive can making machinery at heavy capital expense, with the possibility of having such extra equipment idle for two-thirds of the year, and the resultant expense of interest charges combining to aggregate as much expense as if the extra high freight charges had been paid on the empty cans.
By the present invention the objectionable features above indicated are avoided, and a highly satisfactory type unpacking can is provided.
Other objects of the invention and the various advantages and characteristics of the improved can will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel form, construction and combination of parts hereinafter fully described, illustrated in the accompanying drawing, and finally pointedout in the appended claims.
While the forms of the invention herein shown .and describedare the preferred embodiments struction, and the right is reserved to resort to such changes as lie within thescope of the invention.
In the drawing Fig. 1 is a side elevation of a packing can constructed in accordance with the present invention, the cover thereof being omitted;
8. 2 is a vertical transverse sectional view thereof;
Fig. 3 is a partial transverse sectional view, on an enlarged scale, illustrating one embodiment of the can, and showing themanner in which the cans of that form are packed in nested relation for shipment; and
Figs. 4 and 5 are similarviews illustrating alternative or modified constructions of the can illustrated in Fig. 3.
Referring in detail to the accompanying drawing, the numeral l0 designates the body or side wall of'the hereindescribed can. This is formed of suitable sheet metal designed for the purpose, and its shape is generally tapered from the top to the bottom. The main body portion of the side wall is straight sided, as shown in the drawing, and is uniformly tapered from top to bottom. At its top edge the cup is provided with an outwardly extending horizontally-disposed flange II which encircles the body of the can, and is designed for the purpose of attaching to the body III a suitable cover of the desired construction (not shown). If desired, the flange ll may be omitted, and the upper edge of the side wall of the can permitted to remain free of the flange II, or provided otherwise for the attachment of the cover referred to.
At the lower end of the body III is arranged a bottom II. This may be crimped or otherwise provided with a. suitable formation to impart strength and rigidity thereto.
The lower end of the body I0 is of a reduced diameter so as to permit the application of the bottom l2 to such end in such manner that when the bottom is so applied the outside diameter thereof shall not exceed the external diameter of the body III at a point above such reduced diameter. Preferably, the outside diameter of the bottom l2 should not exceed the diameter of the inside of the body at a point above the tapered portion of the body. The purpose of this will presently appear. In Figs. 3, 4- and 5 of the drawing, differing constructions of the lower ends of the body I! appear. As shown in Fig. 3,
it will be observed that the tapered portion of the body III is in the form of a compound curve 13, in the cross-section of the portion of the body beneath the body ID. The lower end of this tapered portion I3 is truly cylindrical and has a ring-shaped outwardly extending integral horizontal flange M which terminates-in; an upwardly-extending ring-shaped flange l5?! Theflange i4 is received by an outwardly-extending horizontal flange IS on the bottom I2. This flange i6 is of greater width than the flange H connected to the horizontal flange IB by a substantially right angle bend is a substantially verticalflange I! that: embraces or laps the flange IS. The flange ll terminatesv in an inwardly and downwardly bent flange l8 that is received between the upwardly-extending flange l5 and the lower end of the body or side wall of the can. Eventually, the flanges ll, l5, l6, I1 and I8 are tightly crimped together, as by compressing, so as tightly to join the lower end of the body ill to the margin of the bottom l2.
That the Joint between the edges of the bottom l2 and the lower edges of the body l0 may be rendered water-proof, and, therefore, tight against the passage of the liquid contents of the can or admission of air to the interior of the can, a lining I9, preferably in the form of a rub- A paperber paint, is arranged in the joint. washer may be substituted for the rubber paint and serve the same purpose.
In the assembly of a plurality of the cans, as shown in Fig. 3, it will be observed that these are so related or nested that the bottom of each can rests upon the inwardly-extending tapered portion I3 of the can that is immediately adjacent thereto, and disposed immediately therebeneath, as shown in Fig. 3. In this associated relation of the cans the sealed bottom of the super-imposed can rests upon the inwardly-inclined tapered portion l3. In such position the sides of the adjacent cans are separated, as clear- 1y illustrated in Fi 3, so that they do not contact, but are free from engagement with each other, and in such position it is obvious that the innermost can readily may be separated from the can next adjacent thereto when it is desired to separate the several cans from each other.
In the assembled relation of the cans referred to, the positioning of the bottom of each of the innermost cans upon the next adjacent tapered portion I3 ofthe subjacent can, maintain the bottom l2 in separated relation with respect to the bottom of the subjacent can, and this serves also to maintain the free capacity of separation of each of the cans from the next adjacent can on which its bottom rests.
When the cans are assembled in the relation just described, it is important to observe that the bottoms of the several cans do not extend beyond the extreme outer diameter of the body portion of the cans with which the bottoms are assembled. This maintains the stack of the assembled cans in such fashion that there are no projecting portions of the bottoms lying beyond the extreme outside diameters of the can bodies themselves. Thus, the entire stack of cans is maintained in such fashion that no sticking of the respective cans ensues, but there is always perfect freedom for separating the respective cans from the entire stack when this is desired.
In Fig. 4 is disclosed another form of can. As distinguished from the form shown in Fig. 3, the tapered portion has an abrupt shoulder 20, that is, a shoulder having a greater degree of angular inclination than the tapered portion l3 illustrated in the form disclosed in Fig. 3. This affords a more pronounced seat for the lower end of the next innermost can body ID that is arranged in super-imposed relation with the shoulder 20.
The joinder of the bottom I! with the body or side wall of this particular form of can is the same as in the form shown in Fig. 3.
Fig. 5 illustrates another form of the can in which the tapered portion I3 is of greater extent than in the forms shown in Figs. 3 and 4. This tapered portion of the body I. is of less angularity than what is shown in Fig. 4, but the same positions the joint between the bottom I! and the body HI within the outer diameter of the latter so as to position this joint in such fashion as not to extend beyond the sides of the body l0.
The bottom I 2 of the form shown in Fig. 5 likewise is Joined to the body of the can in the same manner as is true of the forms shown in Figs. 3 and 4.
The arrangement of the can bodies in the stacked relation shown and described is such that the conical ends will afford a strong substantial support for the cans above and thereby maintain them in such relationship.
