CAN-CLOSURE, V v
srncrnrcn'rron forming part of Letters Patent No. 751,318, dated Feb ruar 2 19 W Application filed August 12, 1903. Serial No. 169,166. (No model.)
' the following is a complete specification;
- My invention relates to improvements in the class of cans which are commonly formed of sheet metal and are adapted to hold liquids by rendering liquid --tight their closure through the medium of their cover.
My invention relates particularly to the construction of that portion of the can having the opening therein through which access is obtained to the interior thereof and to the covering for such opening'and the object of my invention is to provide a simple but novel construction whichshall not only accomplish the desired eifect of rendering the can-closure perfectly liquid-tight, but produce such tightness of closure by causing a simultaneous contact between various portions of the cover and can that if for, any reason one closure proves ineifective one orthebalance thereof will serve to prevent the escape of the con-- tents of the can and also that such engaging portions may be formed. with such evenness as to prevent air-spaces by insuring perfect.
contact and yet permit the ready removal of the cover of the can when desired.
To the accomplishment of the aforesaid objects my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described, reference being had to the accompanying drawings, forming a part hereof.
In the accompanying drawings, in which similar reference-numeralslindicate like parts in the different figures, Figure 1 is a section through the center of a can, showing the means by which the cover is retained thereon; Fig. 2, an enlarged view of the joint between the cover and'the can. Fig. 3 is a view similar to Fig. 1 of acan-cover having flattened upper portions, and Fig. 4 a simi' lar View with the cover partially removed.
, In the drawings, 1 represents a can which is preferably made of sheet metal, near the upper end of which is an inturnedshoulder 2, from which rises a conical portion 3', the
upper end of which is inwardly turned and curved or flattened at a point 4. and then projects downwardly with an outwardly-conical ishape. the inclination of which is toward" the vertical center of the Can; Adapted to fit over this portion of the can and complete a closure thereof is acap 5, having a centrally-depressed center 6 the sides or walls of which rise-With an inclination directed to-- ward thevertical center of the can and are then rounded or flattened a little larger than the top of the curved portion 4 of the can.
In manufacturing the turn Lin the top of the can it may be made with a perfectly circular form, as shown in Figs. 1 and 2, or with a flattened top and with its edges slightly to the point 7 when it is abruptly turned outward and then rounded, with its under or outer edge directed inward at the point 8; Within this inturned portion 8 of the cover is embraced a washer 9, of suitable material.
In order to effect a complete and absolutely certain joint between the cover and the can, I customarily place a washer or thin layer of cement 10 in the hollow portion of the cover, into which} the curved or flattened end 4: ofthe can projects.
It will be seen that when the canis properl'yfilled ready for closing and the cover 5 is placed thereon there will be five points of contact between the cover and can proper. These five points of contact are, first, the joint between the inner wall of the depressed portion 6 of the cover against the downwardlyinturned edge of the can; This point in Fig. 2 is marked 11. A second joint is between the upper curved ends of the cover and can,
the space between which is filled by a ement' or a washer 10. This joint is numbered 12. A third joint is between the outer wall of the cover and the outside of the upright inclined portion 3 of the can, which point isnumbered 13'. In placing this cover 5 on top of the cantop the washer 9 is slightly smaller in internal diameter than the greatest diameter of the upright portion 3 of the can, so that as the lid is forced downward contact is obtained between the washer 9 and the outside upwardlyturned portion 3. which constitutes the fourth point of contact or closure between the cap and the jar. WV hen this cap 5 has been pushed down snugly upon the jar-top, the under face of the washer 9 presses upon the shoulder 2 of the jar, forming the fifth point of contact between the cover and the jar. It is intended that all these points of contact shall subserve the common purpose of forming a tight contact between the cover and the can.
It is obvious that in the drawings the amount of inclination of the upright portion of both the cap 5 and can 1 are inclined at an angle considerably in excess of what they will be in actual practice, with a view to more fully illustrate the frictional engagement between the cover and the can. This amount of inclination in actual practice may be comparatively slight in order to effect an absolutely tight joint between the two; but in order to more readily illustrate the application of these inclined faces they are to a certain extent exaggerated in the drawings, with this object in View.
Both of the washers 9 and 10 may be of any material suitable for this purpose and are preferably made of material not affected by the contents of the can.
In order to remove the cover from the can, a knife-blade or its equivalent is inserted between the shoulder 52 and the inturned part 8 of the cover, and the cover is readily pried from its seat, permitting access to the contents of the can.
In the use of this can-closure by manufacturers desiring to ship or place on the market a liquid preparation the cover 5 is forced down, as shown in Figs. 1, 2, and 3, which causes the five points of contact to coact, the results of which will be that the outside of the inner wall of the depressed portion of the cover will force outwardly the top 4 of the cantop against the outer wall of the cover,making a tight joint with the upright portion 3 of the can. This in itself will make a substantially air and liquid tight joint and serve to keep atmospheric air from coming in contact with the washer or coating of cement 10, thereby preserving its quality as an excluder of air and a preventive against the escape of the contents of the can and serving to preserve the lasting qualities of this washer indefinitely. WVhen the can reaches the consumer, the lid or cover 5 is raised, allowing free access to the contents of the can, and as it frequently happens in the use of certain kinds of liquids, particularly where a brush is used, the interior of the downward-turned portion of the can-top becomes to a certain extent coated with the contents of the can, thereby preventing the return of the cover to its former position, by reason of the fact that the inner wall of the centrally-depressed portion 6 of the lid cannot enter the downwardly-inclined portion of the can. This objection is frequently met with in a large number of the cans now in use, and Lo overcome this objection my cover is made both an outside-sealing and an inside-sealing one. Hence when the consumer has used a portion of the contents of the can and desires to exclude the air therefrom all that is necessary to do is to press the cover down upon the can-top to about the extent shown in Fig. 4: and the can will be sealed.
It rarely happens that in removing liquids froma can the outside of the portion 3 of the can becomes coated by the contents of the can, and hence this joint is substantially at all times capable of use and insures a .0.1- fect seal for the can. This is aided by the fact that the washer 9 will likewise press against the outside of the upright portion 3 of the can and afford an additional safeguard against the admission of air or the escape of the contents of the can. From this it will be seen that after the can has been opened the first time it may still be used at intervals as required, notwithstanding the fact that the interior of the downwardly-turned portion of the can-top becomes coated with the liquid of the can, as it will be seen by reference to Fig. 4: that the depressed portion 6 of the cover does not reach down far enough to have its inner wall come in contact with the can itself.
What I claim, and desire to secure by Letters Patent, is
1. The combination with a can provided at its upper portion with a slightly inwardly inclined top having a reflected downwardlyturned inner edge, a cover for said can having a depressed central portion surrounded by an upturned groove composed of inner and outer walls, the inner wall to engage said downwardly-reflected edge of said can, said. outer wall to bear against the outer face of IIO said inwardly-inclined portion of the can, said 2. The combination with a can provided with an .inturned shoulder slightly inclined from' which projects an inwardly-inclined portion having a reflected downwardly-turned inner edge, a cover for said can having a depressed central portion surrounded by an upturned groove composed of an inner and outer wall, the inner wall to engage said downwardly-reflected edge of said can, said outer wall of said cover of approximately greater width than the inner wall and having its lower portion abruptly turned upward in substantially areflected end of said can, an outer rim to bear against the outer face of-said upwardly-inclined portion and means at the bottom of said cover to retain a washer, and a washer so retained capable of frictional engagement with the outside of said upwardly-inclined portion and said inclined shoulder.
4. The combination with a can provided at its upper portion with a slightly inwardly inclined top having a reflected downwardlyturned inner edge, a cover for said can having a depressed central portion to engage said downwardly-reflected edge of said can, the greatest diameter of said depressed portion of said cover which is arranged to enter the upper end of said can being equal to or slightly exceeding the opening bounded by the downwardly-reflected inner. edge of said can, an outer rim or wall on said cover to bear against the outer face of said inwardly-inclined portion of said can and-means at the bottom of said outer wall of said cover to retain a washer and a washer so retained capable of frictional engagement with the outside of said inwardlyinclined portion and said inclined shoulder.
In testimony that I claim the above I hereunto set my hand in the presence of two subscribing witnesses.
