SPECIFICATION forming part of Letters Patent No. 731,792, dated. June 23, 1903. Application filed October 6,1962, Serial No. l26,17 7. (No model.)
T aZZwhom it may concern: Be it knownthat I, JOHN KUNKEL, a citizen of the United States, residing at Lazearville, in the county of Brooke and State of .West Virginia, have invented certain new and useful Improvements in J ar-Olosures, of which the following is a specification.
This invention relates to new and useful improvements in closures for bottles, jars, or any other analogous receptacle, and essentially aims to combine a simplicity and cheapness of structure which has not heretofore been attained in the art.
The form of closure embodied by my invention and which is hereinafter more fully described and finally claimed. is of the type utilizing spring-clamp means for securing the same to the jar or other receptacle to which the same is applied. y For a full description of the invention and the merits thereof and also to acquire a closure alone.
knowledge of the details of construction of the means for effecting the result reference is to be had to the following drawings hereto attached.
While the essential and charcteristic features of the invention are susceptible of modification, .still the preferred embodiment of the accompadescription and nying drawings, in whicll- Figure l is a portion of a jar with the invention applied thereto.
Fig. 2 is a perspective view of the Fig. dis a sectional view about on the line X X of Fig." 1. Fig. 4is a side elevation of the clamp alone. Fig. 5 is a top plan view showing a modified form of jar.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Describing the invention in detail, 1 designates the body portion of a jar, a jar being shown merely to illustrate the application of the idea, it being understood that any other receptacleof a jar or bottle nature may be employed, if desirable. ,The mouth of the jar shows the rim 2 of flaring form, an annular groove being formed upon the said rim. The inner edge of the rim 2 is approximately below the plane of the outer edge, as
perspective view of the upper will be readily noted upon reference to the drawings.
The closure comprises a body at, flanged at the upper part thereof, said flange being numbered 5, and a clamp member 6. A raised portion constituting abutton 7 is formedupon the upper surface of the body 4 of the closure, and this portion is undercut at diametrically opposite points in the sides thereof, as indicated at 8. N otches 9 are located upon the surface of the raised portion 7, which notches and same communicate in their cut-away extent with the undercut portions 8.
The remaining elementof the closure is the spring-clamp piece 6. This member 6 when operatively connected to the closure 4 is affixed thereto in such a manner that accidental displacement therefrom is impossible, this feature presenting in itself a very essential advantage. The clamp consists of a strip of spring sheet metal or the like and is bent l11' termediate its end portions at 10 to form a raised part 11. The portions 10 are bent at an angle to the part 11, in fact, forming in the preferred embodiment of the device an acute angle with the plane thereof. The end portions of the strip or clamp-piece extend from the bent portions 10 for a short distance in.
parallel relation to the part 11, and the extremities are downwardly bent to form hooks -12, which snap over the sides of the rim 2 of the jar. One of the hooks 12 preferably turns slightly outward, so as tomore readily ride over the rim when the fastener is snapped inplace. The bent portions 10 ofthe clamp extend into the undercut portions 8 of the button 7, also engaging the notches 9, and lock the fastener thereto in such a manner that all danger of accidental displacement is avoided. It will be seen, however, that the saidclamp-piece G is adapted to beremoved when desircd for instance, in cleaning the closurebeing sprung back into place when again assembling the parts.
A rubber gasket 13 is placed upon the rim, lying over the groove therein and about flush with the outer edge thereof. An annular bead 14, provided upon the under side of the flanged portion 5 of the closure, cooperates inapplying same to force the gasket into the groove, thereby rendering the closure abso- ILO lutely air-tight-another desideratum not found 1 in the 1 ordinary closure.
In the modification Fig. 5 cam or inclined riding surfaces are formed upon the outer side of the rim of the bottle-mouth, and these serve, in conjunction with the engaging hooks of the clamp member 6, to force the closure into the mouth of the bottle upon a circumferential movement of the closure giving a maximum amout of pressure thereon. The raised portion or button 7 may be used in turning the closure, affording a means for gripping same which greatly facilitates the action.
The clamp-piece 6 will turn with the closure,
owing to the connection therewith which has been above described.
I am not to be restricted to the exact construction illustrated in the drawings, but reserve the privilege of modifying the details thereof according to the broad spirit of invention in accordance with the scope of the appended claims.
Having thus described the invention, what is claimed as new is 1. In a device of the character described, a jar or like receptacle, a closure of approximately disk form adapted to be seated in the mouth of said receptacle and provided upon the upper surface .thereof with a central raised portion, a clamp member adapted to make spring interlocking connection with the edges of the aforesaid raised portion of the closure, the end portions of the said member being bent to form hooks, said hooks engaging overthe rim of the receptable when applying the closure thereto, substantially as described.
2. In a device of the character described, a jar having a grooved rim at the mouth thereof, a disk closure having an annular flange at the upper portion, said flange partially overlapping the rim of the jar, araised portion or button centrally formed upon the upper surface of the closure, a clamp piece bent intermediate its ends to form spring engaging parts cooperating with the aforesaid.
button to hold the clamp upon the closure, the ends of the clamp-piece being bent to form hooks to spring over the rim of the jar to secure the closure thereto, substantially as described.
3. In a device of the character described, a jar or like receptacle providedwith a grooved rim and a gasket adapted to be seated in the rim over the said groove, a disk closure having an annular flange adapted to partially extend over the rim of the jar, an annular rib or bead located upon the under surface of said flange and adapted to force the gasket hard against the grooved portion of the rim, a button centrally disposed upon the closure and having undercut portions at diametrically opposite points thereon, a springclamp fastener bent intermediate its ends to provide engaging portions adapted to spring into the undercut portions of the button to hold the clamp-piece thereto, the ends of the clamp-piece being bent to form hooks to engage over the rim of the jar to secure the closure thereto, substantially as set forth.
4. In a device of the character described,
a jar provided with agrooved rim at the mouth thereof, inclined surfaces formed at approximately opposite points on the sides of said rim, a disk closure provided with an annular flange adapted (annularly flanged) to partially overlap the said rim, an annular rib upon the under surface of the flange aforementioned, a gasket seated in the rim above the groove therein, a button centrally disposed upon the closure, undercut portions located at diametrically opposite points on the said button and notches upon the surface of same and communicating in their cut-away extent with the undercut portions thereof, a spring-clamp piece bent at points intermediate its ends to provide spring-arms to engage with the undercut portions of the button and also bent at the extremities to form hooks to engage the sides of the rim, said hooks being adapted upon an approximately circular movement of the closure to ride upon the inclined surfaces of the rim and firmly secure the closure in position, substantially as described.
, In testimony whereof I affix my signature in presence of two witnesses.
