4 Claims. (Cl. 220-67) This invention relates to cans of the type comprising a body section and a conical neck section which are secured together by a double lock' Seam.
One of the objects of the invention is to pro-v vide a can of this type which presents-nofappreclable interior shoulder at the joint between the body section and neck section.
A further object of the invention is to provide a can of this type in which the double lock seam is so formed that the can presents no upstanding. rib on its exterior at the joint between the neck section and body section.
A further object of the invention is to provide a can of this type in which the double lock seam is reenforced by means of a reenforcing fold formed in the neck section, and a further object is to provide a can of this type in which the conical neck section is strengthened or reenforced by forming therein ribs extending from the base toward the top.
Some cans of this type are provided at the top of the neck section with an external bead to which a sealing cap is crimped for sealing the can. and a further object of the invention is to provide a can of this type which will Withstand the pressure to which it is subjected when the sealing cap is being crimped thereto without danger of giving or buckling at the joint between the neck section and body section.
Other objects of this invention are to'improve cans of this type in the various particulars hereinafter set forth.
In the drawing wherein I have illustrated some selected embodiments of my invention;
Fig. 1 is a sectional view showing the body section and neck section of a can assembled ready for the formation of the double lock seam by which they are connected, said section being on the line I-I, Fig. 3.
Fig. 2 is a fragmentary sectional view showing the double lock seam completed and illustrating the reenforcing fold in the neck section, said section also being on the line I-I, Fig. 3, but
with the chuck and can having a different angu,
lar position from that shown in Fig. 1.
Fig. 3 is a fragmentary plan view of the seaming roll and a portion of the can being acted on.
Fig. 4 shows a different way of supporting the ,seaming chuck than that illustrated in Figs. 1
and 2.
Fig. 5 is a fragmentary view showing a different embodiment of the invention.
Fig. 6 is a fragmentary section through the neck portion of the can on the line 6--6, Fig. 3.
The can herein shown comprises the body section I and the conical neck section 2 which are I secured together by the double lock seam ndicated generally at 3. The neck section I is'provided at its lower edge with a depending fold 4 which is of a shape and size to fit within the upper end of the body section I. The inner ply of the fold 4 constitutes a depending substantially cylindical vertical rim portion depending from the lower edge of the conical portion 2 of the neck section. The fold 4 is made by folding the material of the wall of the neck section back on itself as illustrated. The above described construction provides a can which presents no upwardly opening pocket on its interior at the joint between the neck section'and the body section. In the construction shown in Fig. 2 the neck section is also formed with a. second fold 5 which is'in the nature of a reenforcing fold and which is located on the exterior of the neck section immediately above the double lock seam 3, said reenforcing fold 5 lying flatly against the wall of the neck section.
In the preferred embodiment of the invention the wall of the neck section is provided with an annular indentation 6 to receive the reenforcing fold 5 so that the outer face of said fold 5 comes ilush with the outer face of the neck section 2. e
In making the can having this construction the body section I is first formed in the usual way as a cylindrical member open at both ends and having a seaming flange I extending loutwardly from its upper end. The neck section 2 is then formed with its conical-wall and the lower edge of the Wall is folded back on itself to form the annular depending fold 4 which, as stated above, is of a size and shape to fit within the upper end of the body section I. The neck section may also be formed to present an upstanding annular fold 5, as shown in Fig. 1, o which encircles its base, and the edge of the neck section is deformed to present the outwardly-extending seaming flange 8.
In connecting the body section and neck section, these parts will be assembled as shown in Fig. 1 with the depending fold 4 of the neck section fitting within the upper end of the body section and with the two seaming flanges 'I and 8 in mating relation. These seaming ilanges are then rolled into the double lock seam, and at the same' time the upstanding fold 5 is bent over into contact withl the exterior of the neck section. These Ioperations can be conveniently formed through the medium of a seaming chuck 9 adapted to be inserted into the interior of the body section I and neck section 2, and a seaming roll I constructed to act on the mating seaming anges 'I and 8 and roll them into the double lock seam, the chuck forming the necessary backing for the body section and neck section during the seaming operation.
If desired the neck section may be formed initially with the sunken or depressed annular portion 6 immediately above the fold 4 and into which the reenforcing fold is forced by the seaming roll so that when completed the exterior face of the fold will be ush with the exterior conical surface r the neck section 2.
The chuck 9 is shown as supported on a rotating spindle II andl in the construction shown in Fig. 1 it has the cylindrical body portion which ts the interior of the can body and the conical upper portion which fits the interior of the cone-shaped neck section. The chuck has associated therewith a supporting ange I2 on which the lower edge of the body I rests during the seaming operation. A suitable bearing is provided for the upper conical end of the chuck for the purpose of assisting the chuck to resist any transverse pressure due to the operation of the seaming roll. In the construction shown in Fig. 1 the upper end of the chuck is provided with a recess I3 in which is received the end I4 seaming roll I9 hasa general conical shape a'nd is provided in its periphery with a curling groove 20 arranged to engage the edges of the seaming flanges I and 8 and to roll them into the double lock seam during the rolling of the seaming roll around the can as usual in the making of a double lock seam. y During this seaming operation the conical faceA 2I of the seaming roll engages the upstanding fold 5 and forces the same inwardly into contact with the exterior wall of the neck section, and if the neck section is formed with the annular recess 6 then this fold 5 will be folded into the recess so as to be flush with the exterior Wall of the neck section.
I will preferably deform the wall of the body section I, as shown at 22, so that the interior diameter of the body section at this point will be the same as that of the interior diameter of the folded portion 4. 'Ihere will thus be provided a cylindrical chuck-engaging surface composed of the deformed portion 22 of the body and the depending fold 4 which is backed by the chuck 9 during the seaming operation. 'Ihis deforming of the body section can be accomplished by reducing its radial dimension at the point 22 by an amount equal to the thickness of the fold 4.
It will be understood that either the seaming roll I0 'or the chuck 9 or both will be positively driven during the operation of rolling the seaming fianges I and 8 into the double lock seam 3v. In Fig. 5 there is shown a can which is similar to that illustrated in Fig. 2 except that the reenforcing flange 5 is omitted, the neck section being provided simply with the depending fold 4 and with the seaming flange 1.
The can herein illustrated is provided with a substantially vertical throat extending upwardly from the conical portion of the neck section 2, said throat having an exterior bead 25 at its upper end to which any usual sealing cap may be crimped. At the upper end of the throat the can is provided with a central opening through whichthe contents thereof may be discharged. Surrounding said opening and Within the annular bead 25 is a substantially horizontal annular strip of metal which constitutes a sealing lip.
In a can embodying the present invention the lower end of the conical neck section 2 has substantially the same diameter as the body section and the can presents no f appreciable interior shoulder at the joint between the neck section and body section. This construction is of special advantage when the can is used for putting up beer or any other similar beverage which foams or effervesces when poured out. The presence of an appreciable shoulder at the junction of the body section and neck section forms a sort of baie over which the liquid has to flowwhen the can is being emptied and the presence of such a baffle causes undesirable foaming or eiervescing in the case of beer or similar beverage.
My improved can provides a relatively smooth interior surface over which the liquid may ow freely without being agitated when the can is emptied.
The operation of applying and crimping a sealing cap to a. can of thisltype involves the application of considerable downward pressure on the neck. The construction of my improved can is such that it admirably resists such downward pressure without any tendency to buckle. Since the base of the conical neck has approximately the same diameter as the can body the downward pressure to which the can is subjected when the sealing 'cap is being crimped thereto is conveyed through the neck section directly to the walls of the body section through the fold 4, and thereby the tendency of the neck section to buckle is prevented.
The presence of the reenforcing fold 5 also stiens the can at the joint between the neck section and body section and adds further strength at this point. n
Furthermore, my improved can presents a relatively smooth exterior surface at the junction of the neck section and body section which is free from any upstanding ridge or shoulder that forms an annular pocket in which dirt and dust are apt to gather. The exterior surface of my improved can is relatively smooth except for the double lock seam 3 and in practise this forms a relatively thin rib, said double lock seam being shown exaggerated in .size in the drawing in order to make the construction clear.
The conical neck section is also shown as having ribs formed therein extending from the base toward the top. Such ribs are indicated at 26 and they are in the form of internal ribs made by deforming the neck section to produce the external elongated indentations. The chuck 9 has the annular groove 21 situated to receive these indentations 26 during the seaming operation.
The conical shape of the seaming roll preferably corresponds to that of theneck section 2, and during the action of the seaming roll on the seaming flanges for theiproduction of the double lock seam the conical portion of the seam-v ing roll above the curling groove serves to prevent the seeming flanges from buckling upwardly unduly and thereby assists in rolling the flanges into the double lock seam. When the seam is completed the conical face of the seaming roll will be resting against the conical Vface of the neck section as shown in Fig. 2.
I claim:
