CLOSURE FOR PACKING AND STORING VESSELS.

SPECIFICATION forming part of Letters Patent NO. 689,896, dated December 31, v1901.

Application filed May 25.1901. Serial No. 61,830. (No model.)

T0 all whom, t may concern:

Be it known that I, GEORGE MANIERRE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Closures for Packing and Storing Vessels, of which the following is a full, clear, and exact specification.

This invention relates to closures for cans and other vessels and more particularly to that class which employ a screw-cap and a compressible gasket; and it has for its primary object to provide an improved closure in which a common rubber band of commerce may be employed as a gasket without danger of entangling the band with the screw-threads, resulting in not only destroying the band but preventing the closure from forming a perfect or hermetic seal.

Another object of the invention is to have the faces of the parts which engage the band of such formation that a band of any shape in cross section may be employed, or the twisting of a dat or irregularly-shaped band will not prevent the parts from forming a tight joint therewith.

A further object of the invention is to so form the parts that the rubber band or gasket will be hermetically sealed by the parts between which it is compressed, and thus shielded from the deterioratinginfluences of the atmosphere.

Vith these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangements of parts by which the said objects and certain other Objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure l is a vertical sectional view of my improved closure, taken on a line l l, Fig. 2, showing the parts tightened up. Fig. 2 is a similar section taken on theline 2 2, Fig. l, showing the cap backed off from the neck.

lis a part of the body of the can or other receptacle upon which the neck 2 of my improved closure may be formed or otherwise secured. This neck 2 is threaded at its inner end, as shown at 3, and throughout the threaded portion it is substantially cylindrical or of a uniform diameter from end to end. At the upper end of the threaded portion 3 the neck is flared outwardly, as shown at 4, to give it a slightly-greater diameter than .the maximum diameter of the threaded portion, and from this outwardly-'daring turn 4 it is carried upwardly to the point 5 in a substantially perpendicular or cylindrical form,where it again begins to turn outwardly to form a wide flaring mouth 6, having an unfinished or feather edge 7, which is more or less flexible, for a purpose which will be presently described.

The cap which engages with the threaded neck described for closing the latter is struck up from a sheet of thin metal or other suitable material, as clearly shown in the drawings, in a hollow form, open at top, but having a closed bottom 8. The lower or inner end of the body portion of the cap is threaded, as shown at 9, throughout that portion thereof which is within the threaded portion 3 of the neck, and from the point 10, which is above the top thread and substantially opposite the outward flare or curve 4 of the neck, the body portion of the cap dares outwardly at a less angle than the flare 4, but at a greater angle than that portion of the neck between the points 4 5, so that there will be constituted on the body portion of the cap a plain surface between the point l0 and apoint 1l above the point 5 when the parts are together and a plain ungrooved tapering surface which gradually inclines toward or converges with the cylindrical part of the neck between Ithe points 4 5. From the point 11 upwardly the plain surface of the body part of the cap rounds outwardly into a greater flare than the angle of flare between the points l0 11, thus forming a concavity l2 around the upper end of the body part of the cap, which concavity 12 is of sharper curve than the curve of dare G, so that when the parts are screwed together in the manner shown in Fig. 1 the featheredge 7 of the neck may touch the cap and. the shoulder on the neck formed by the outward bend or curve at the point 5 may come into close propinquity to the cap, while a considerable space will be left between the cap and neck from the point 5 to the point '7 for the reception of a rubber band 13, which may be a common strap of commerce without regard to the shape of its cross-section.

In the use of the device the rubber bandl will be stretched over the body part of the cap and pushed down approximately onto the plain ungrooved surface thereof lying between the points 10 11, the object being to place it approximately in the concavity12; but with the class of labor ordinarily employed for such work it is practically impossible to Adepend upon the band being left at any particular point on the plain surface, and hence it is necessary to count on the band being found at various points between the point.10 and the concavity 12 when the cap is taken up to be screwed into the neck. It is for the purpose of guarding against damage to the band and causing the band to automatically find its seat in the concavity l2 that the neck between the points 4 5 and the cap between the point 11 and the top thread are given the peculiar relative angles and formation. Assuming, for example, that the band is left on the plainsurface of the cap in the position shown in dotted lines in Fig. 2, it will be seen that as the cap is screwed into the neck the shoulder of the neck at the point 5 will engage the band and crowd it upwardly on the cap to its proper seat in the concavity 12, as shown in Fig. 1, without permitting the screw-threads to engage and cut the band or the band to become entangled with the screw-threadsin such manner as to prevent the formation of a perfect seal. It will also be seen that owing to the dierence in flare or angle of the concavity 12 of the cap and the flaring mouth of the neck the upper or outer edge of the concavity 1 2 will impinge firmly against the feather-edge 7 of the mout-h of the neck and completely inclose the band 13, and the edge 7 being more or less iiexible will readily conform to the cap where it touches the latter and permitk of much more intimate contact between the parts than would be possible if` said edge 7 were K beaded or finished.

From the upper or outer edge of the curve or concavity 12 the material of the cap is carried outwardly and slightly downwardly in a gradual curve 14, forming with the curve 12 a compound curve, which coperates with the feather-edge 7 in constituting a seal for the band, and from the outer end of curve 14 thev cap rounds downwardly and upwardly, constitutinga gripping flange or knob 15, whose upper edge is turned inwardly, as shown at 16, to strengthen and stiffen it. The flange 15 16 when thus constructed is of sufficient rigidity to make it feasible to provide wrench A sockets or notches 17 in diametrically oppoat the outer end of said cylindrical part,a cap having a body portion threadedv at its inner end and a plain ungrooved slightly-conical portion at its outer end flaring out above said neck into the form ofalateral extended flange, said plain portions being adapted to come opposite each other when the cap is screwed into place, and a rubber band surrounding said plain portion of the cap', `substantially as set forth.

2. In a closure, the combination of a neck having a thread ed part at its inner end and a plain ungrooved flaring part at its outer end of larger diameter than said threaded part, a cap having a body portion threaded at its inner end and fitting the threads of said neck and provided at its outer end with a plain ungrooved part located opposite said plain part of the neck and being considerably less in diameter at its lowest part than said plain part ot' the neck whereby a space will be left between said plain parts, the plain part of the body of the cap being flared or turned toward the flaring part of the neck, and a rubber band surrounding said plain part of the body ofthe cap, substantially as set forth.

3. In a closure, the combination of a neck threaded at its inner end and having a plain ungrooved flaring mouth at its outer end, a cap having the body part threaded at its inner end and provided at its outer end with a plain ungrooved flaring part of smaller diameter than said mouth and curved toward so as to touch the extreme outer edge of said mouth when the cap is screwed into place, and a rubber band surrounding the plain part of said cap, substantially as set forth.

4. In a closure, the combination of a neck having screw-threads at its inner end, and a plain ungrooved flaring mouth provided with the flexible edge 7, a cap threaded at its inner end in said neck and having a plain part opposite the plain part of said neck and a flaring flange pressing said flexible edge 7 when the cap is screwed into-place, and a rubber band surrounding the plain part of the said cap, substantially as set forth.
