CHARLES HAMMER, OF HOLLIS, NEW YORK ASSGNOR [10 AMERICAN METALKCAP COMPANY, OF BROOKIIIZN,Y NEW YORK, A CORPORATON 0F NEW YORK RESEALAELE METAL CAP.

Application filed July 29, 1926. Serialy No. 125,647;

|This invention relates to resealable caps or closures for containers, the object of the invention being to provide an improved cap adapted for use with containers having locking lugs or threads and a shoulder therebelow and particularly adaptedV tor use with glass containers of the construction described.

A further object of the invention is the provision of an improved resealable cap having means for engaging projections or threads of the container to lock the cap on the rotation thereof and spaced integral means for engaging the shoulder of the container, the construction being such that the last holding means may be easily released without an unnecessary waste ot time and labor and which cap is simple `in construction, economical tomanufacture and readily applied, and by means ot' which the ccntainer maybe properly resealed by the user andirby means of which'al'sothe purchaser may readily determine whether the contents havebeen tampered with.

Resealable caps as commonly vconstructed comprise a rotatable cap ,and al separable scalable band engaging the shoulder of the container all around the same. rlhissealing band usually overlaps the skirt ot the cap softhatthis form of reseal closure necessitates-'theuse of twice the amount otmetal at the: skirt of the` cap which makes it ei;- pensivevwhile the resealing band requires timeand considerable laborv to apply. The presenti improvement obviates'the necessity of; providing ya .separate sealing band, thereby reducing the quantity of metal required in the manufacture of. suchy caps and consequently the; expense of production. Furthermorefinthe ordinary reseal capshaving a; separable sealing band 'it is necessary to remove `the band in order to release the cap and. consequently the band can performno function in the resealingl of the container, whereas in the present improvement the shoulder: holdinggportion, even after it has ybeenreleasedto permit the cap to -be usedby the purchaser-,is in such positionlthat it will,

because f of' its resiliency, frictionally engage that, shoulder and assist in holding.A the cap oni the' container even withoutY the l necessity A0J? rotating the. cap. into position. rlhereoreythepresent improved capis not only more economical to manufacturefbut it has be hereinafter explained.

' portion 6 byforcing or projecting the'metal certain advantages over the ordinary reseal cap.- v

V:[n-the drawings accompanying and forming a part of this speciiication, Fig. 1 isan inverted view of this improved cap.- Fig..2 illustrates a portion of the container and a partly sectional view of the cap applied thereto having one form of locking lug. Fig. 3 is a similar view to Fig. 2, but illustrating a dierent form of lockinglug. Fig. 4: illustrates a similar construction to'that shown in Figs. Qand 3 but shows the oa with aditlierent form ot locking projection.

The container is shown in the present instance asa glass container 2, although this improved cap may be used with various forms of containers, and is provided withV a plurality 'of locking threads 3 andl spaced therebelow a shoulder 4. The cap in its preferred form comprises top 5 andadependf ing flange or skirt 6 having at intervals 75 therearound a plurality4 of depending skirt -forming portions 7. The-flange 6 of the cap is shown as relatively shallow with its lower edgey spaced labove the shoulder or" the container as at 8, the purpose of Vwhich will Located between and in alternation witlrthe skirt portions 7 of the cap, the skirt 6 is-'providedwith a plurality of inwardly extending locking projections. rFliese may be ci variousforms.

in Fig. 2 these projections 9 are shown as of wedge shape or thread like form, the

skirt being pressed inwardly to form these projections. In Fig. Sthese projections 10 are formed by slitting the metal of the vskirt at the top of the projections and pressing the metal below the slit inwardly to form the projections; in Fig. el, the projections l1 aretormedat the lower edge ot the skirt otl the skirt inwardly without slitting the skirt. Any of these various forms of locking projections, as well as other torms-there- Y of, may be used if desired, the several` figures being merel intended to illustratesome of the different `orms that may be used successfully. y Before explaining in detail the. present improvement and mode of operation thereot, I'desire to have itA understood that the invention is not limited to. the detailsof construction and arrangement# of parts which are illustratedin the accompanying drawings, since the invention is capable of other einhodnients, and that the phraseology which I eniploy is for the purpose ot description and not ot liaiitatio i In the application of this improved cap to a container `it rotated to bring the locking' lugs into engagement with the holding projections or threads oli' the container and then hun siiitahle inaehhier),Y the lower edges oi the depending shirt portions 7 are span inwardlj1 under the shoulder.` ln those 'aises where it is def-iired to vacnnni seal the container, a suitable liner plate, gasket or other sealing incans as l2, located at the top ot the cap only be used. Then it is desired to renlore the cap from the container, it is merel),`v` necessarjY to insert a sharp instruineni, such as the prong ot a toi-lg in the space il hetween the shoulder and the lower edge oi the shirt portieri (5 oi the capi this apa-cc being' provided especially lor this prirprr-a,` whereupon a dcpcnding shirt portion may he readiljr released and thcronpon the cap inay he quickly rotated oil the contaiinn. .ln resealing the cap, it merelyi necosfairjfto rotate the cap hach into position on to the container. However in tuant7 instances` eren this is not rcijuireih as the incre ajnilication oi the cap to the container without the rotation thereo't will bring the depending shirt portions T into engagement with the shoulder ot the container and owing to the resiliency thereof, the cap will he tristionallj'v held in place. j

'.lrhns, l have provided an improved reseal cap which, owing' to the ainal] anionnt ot metal required tor the inannt'mlftare there o'i' as compared with the ordinariT .rcseal cap requiring' an annular bauch can he econoinically mann'tactnred at nnich .less cost and which, moreover, can he used to reseal the container1 lacing held thereon either hy rotation or lijf friction4` as desired. j In practice, the cap j n'orided with suitable corrngations which not onljY rein'lorce the shirt but 'Facilitate the inannliactnre oitI the cap while :it th, naine tinte they provide a rong'henod snr'lace lor niore readilyT rotating' the cap into and ont ot position and in certain instances, il desired, the lower portions oi the shirt proper niay he headed or strengthened and the lugs or projections formed therefrom or thereaboreD as the case may he.

1n the Atorni ot cap shown it will be observed that the depending shirt forming portions T are ot suhstantiall)7 the saine width cirenln'terentially as are those portions of the shirt proper between the depending portions so that the cap is not onljv sjnnnietrical, but the depending j iortions` T provide relatively long holding surfaces upon the shoulder oi the container.

.it iste be understood that hy describing in detail herein anj1 particular torni, strucn `tnre or arrangeinent`7` it lis not intended to .limit the invention beyond the terms ot the several claims or the requirements olf' the prior art. i j
