CLOSURE FOR JARS Filed Aug. 28. 1928 Patented Dec. 24, 1929 NET STATES THOMAS L. TALIAFERRO, OF CHICAGO, ILLINOIS CLOSURE FOR JARS Application filed August 28, 1928.
The, invention relates to new and useful improvements in a closure for jars, and more particularly to a closure for a jar having a smooth outer wall with which the closure has frictional gripping engagement.
An object of the invention is to provide a closure of the above type including a cover portion and a securing band which frictionally grips the side wall of the j arfor retaining the cover on the jar, wherein said band is divided and the ends thereof are firmly but detachably secured together so that the closure may be readily removed from the jar without the use. of special tools.
A further object of the invention is to provide a closure of the above type wherein the ends of the band are secured together by a reinforced holding lug and a reinforced opening tongue.
A still further object of the invention is to provide a closure of the above type wherein said securing band is formed with inwardly extending spaced ribs having the inner faces thereof spaced diametrically across the band a slightly less distance than the outer diameter of the standard jar with which said closure is to be used, when the band is expanded to the maximum diameter permitted y the securing means which joins the ends thereof.
These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.
In the drawings which show by way of illustration one embodiment of the invention:
Figure 1 is a top plan view of a portion of a jar having the improved closure applied thereto.
Fig. 2 is a view partly in side elevation and partly in section of the same.
Fig. 3 is an enlarged section on the line 33 of Fig. 2.
The invention is directed to a closure for jars, and more particularly to a jar having a smooth outer wall which is substantially vertical. The closure includes a cover portion having a channel adjacent the outer edge thereof in which a sealing composition is placed, forming a gasket which adheres to the cover portion and forming a unit struc- Serial No. 302,619.
ture therewith. The sealing gasket engage the lip of the when the cover is placed thereon. The closure also includes a holdin band which is divided and the ends of the band are secured together by a reinforced locking lug passing through a slot in a reinforced opening tongue. The locking lug is folded back against the face of the tongue so that the ends of the band are firmly joined and held to a maximum diameter. This holding band is provided with a port-ion which overlies the cover, and a depending skirt or flange. After the ends are joined the cover is placed in the formed band and then the skirt or flange of the band is provided with inwardly projecting ribs. These ribs are located immediately below the outer edge of the cover portions and SGIXQ to hold the cover portions in the band so that they may be handled as a unit structure when being applied to the jar.
The lower edge of the band is also turned preferably inwardly for reinforcing the lower edge of the band and concealin the raw edge of the metal. This portion or the band may be turned outwardly for reinforcing the edge.
Referring more in detail to the drawings, the improved closure is shown as applied to a jar 1. The outer wall of the ar adjacent the upper end thereof is substantially vertical, as indicated at 1. The closure includes a top portion 2 which is centrally depressed and otherwise shaped so as to form a channel portion 3. On the under face of the channel portion 3 there is a sealing material which is preferably applied so as to form a sealing gasket of substantial thickness. lVhen the cover is placed on the jar this sealing material engages the lip of the jar and forms a sufficient sealing means for the jar.
The closure also includes a holding band 5 which is provided with a portion 6 adapted to overlie the cover portion of the closure. It is also provided with a depending skirt or flange 7. The band is divided. The dividing line across the horizontal portion of the band is indicated at 8 in Fig. 1 of the drawings, and the line of division through the skirt or flange is indicated at 9. Formed integral with one end of this band is an opening tongue 10 reinforced about the edge thereof, as indicated at 11. This tongue 10 is provided with an opening therethrough which is indicated in dotted lines at 10 of the drawings. The other end portion of the band is provided with a holding lug 13. This holding lug is provided with a central rib 13 which reinforces the holding lug and strengthens the same. he holding lug is passed through the slot 10 and is then folded down against the opening tongue in the well known way. This forms a very rigid means for joining the ends of the band, and the band can be very readily opened at any time by raising the tongue 10. This can be accomplished .without the use of any special tools.
The band is expanded to the maximum diameter permitted by the joined ends, and while thus expanded the skirt or flange 7 is indented so as to provide holding ribs 17. The band is held expanded preferably by an expansible chuck or inner die, and the indentations are forced inwardly so that when the band is thus held at its maximum expansion permitted by'the holding means, the distance from the inner face of one formed inuentation diametrically across to the opposed formed indentation is just slightly less than the diameter of the outer wall of the standard- 'jarwith which the closure is intended to be used. Thus it is that when the closure is placed on the jar, the band, while more or less loosely joined at its meeting ends, will be expanded to its maximum diameter where it will be firmly held and then the indented portions will be forced onto the jar and firmly grip the outer wall thereof. It is well understood thatwhere indentations are used forsecuringa closure to a jar through the frictional grip of the indentations on the wall of the jar, when the grip is a very firm grip, considerable difficulty is experienced in removing the closure. y the present construction it will be apparent, however, that the indentations may be so proportioned that the jar will be very firmly gripped by the'holding band and at the same time the band may be readily removed by lifting the locking tongue and thus separating the ends of the band.
The lower edge of the skirt is preferably turned inwardly as indicated at 16 for the purpose of reinforcing the skirt and also for the purpose of concealing the raw edge of the metal. It will be understood, however,
that this skirt may be rolled outwardly at the lower edge for r inforcing purposes.
' The essential feature of the invention resides in the provision of a band wherein the ends thereof are detachably but firmly secured together with the indented portions formed between the upper and lower edges of the band, which indented portions firmly grip the outer wall of the ar for holding the-band thereon, and these indentations also serve to hold the band and the cover portion assembled as a unit for the handling of the parts during the applying of the closure to the jar.
As noted above, the indentations in the skirt of the holding band secure the top portions to the band, but the indentations are so positioned that there is some freedom of movement of the top portion relative to the band. This is quite essential as it is desirable, when applying the closure to a container having a boiling temperature, to permit the top portion to move into sealing contact with the jar after the product cools so that the top portion will be held to the jar by the vacuuni created therein. The band holds the top portion on the jar and prevents it being separated therefrom until the band is removed, but the top portion will be drawn into tight contact with the jar without requiring any further movement of the holding band which grips the side wall of the jar.
lVhile the indentations 17 are shown in the drawings as of considerable length, it will be obvious, of course, that these may be otherwise formed. It is desirable, however, that the gripping surface shall consist of spaced projections as a better grippinghold is obtained upon the jar wall.
It will be obvious that minor changes in the details of construction and arrangements of parts may be made without departing from the spirit of the invention as set forth in the appended claims.
WVhat I claim as new and desire to secure by Letters Patent is: l
1. A closure for jaws having an outer' smooth substantially vertical wall comprisinga cover portion having a sealing gasket attached thereto, a divided holding band having its ends firmly secured together by an easy opening holding means, said holding band having a horizontal portion overlying the cover and a depending skirt, said depending skirt being provided with spaced inwardly projecting portions for securing the cover to the holding band and for gripping the vertical wall of the jar for securing the closure to the jar;
2. A closure for jars having an outer smooth substantially vertical wall comprising a cover portion having a sealing gasket attached thereto, a divided holding band having its ends firmly secured together by a reinforced holding lug and an opening tongue, said holding band having a horizontal portion overlying the cover and a depending skirt, said depending skirt being provided with spaced inwardly projecting portions for securing the cover to the holding band and for gripping the vertical wall of the jar for securing the closure to the jar.
3. A closure for jars having an outer smooth substantially vertical wall comprising a cover portion havinga sealing. gasket attached thereto, a divided holding band having the ends thereof firmly secured together by a reinforced holding lug and an opening tongue, said holding band having a horizontal portion overlying the cover and a depending skirt said depending skirt being provided with spaced inwardly projecting portions for securing the cover to the holding band and for gripping the vertical Wall of the jar for securing the closure to the jar, the distance between the inner face of opposed projecting portions being slightly less than the maximum diameter of the jar to Which the closure is to be applied when said holding band is of the maximum diameter permitted by the holding lug securing the ends together.
In testimony whereof, I aiiiX my signature.
