A primary object of_ the invention is the pro a closure of the construction illustrated in Fig. 1 secured thereto; Fig. 6 is a sectional elevation corresponding to Fig. 5 and showing the relationship of the closure and container after the former has been detached 5 'from the latter as in process of being removed or stopper, of tamper-proof character, in that the from or replaced on the container; and Fig. '1 is a sectional elevation of a modified form stopper or closure cannot be removed without vision of a package having a removable closure showing plainly that it has been, and certain fea i) tures of the closure are permanently destroyed incident to lts'remeval, thereby preventing its re-use in the original condition, although per mitting the continued use of the closure as an effective stopper for the container. Another object is the provision of such a closure which will form an hermetic seal on an appro priate container, and which is not subject to 20' of closure embodying the invention. For the packaging of liquors or other commod- 10 ities it is frequently desirable to employ a pack age of such character that it may be immediately ascertained whether or not it has been opened. It is quite desirable that the closure or stopper for the container be of such character that it may 15 be continued in use, after its initial removal, to form an eiîective closure for the container, and deterioration with age or from contact with the that it be susceptible of subsequent re-application packaged material. and removal to permit dispensing of portions of Yet another object is the provision of such a closure which may be manufactured economi cally, applied to the container with facility, and removedv without requiring the use of a special the packaged contents from time to time. Here tofore various devices _intended to serve this pur pose have been provided, same including a stop implement. velops the cork and is secured to the container, lYet another object is the provision of such a closure which is neat and ornamental in appear ance and which may bemanipulated with facility such sheath being severable more or less readily 25 ' in removing it from and re-applying it to the container. Other and further objects will be pointedV out or indicated hereinafter, or will be apparent upon an understanding _of the invention òr its employ ment in use. ` per, of cork or the like, and a sheath which en to permit access to the stopper for removal there of. Such devices do not adequately fulfill their `~ purpose due to the fact that the sheaths are of ' relatively simple character and separable from the stopper, thus permitting the package to be 30 restored to its original and unopened appearance simply by the application of a new sheath to the container and the original stopper. The present invention provides a closure in which the sealing element is of distinctive char- 35 acter and is permanently a part of the sheath For the purpose of making clear the nature of the invention, I showin the accompanying draw ing forming a part of this specification, and here inafter describe, one form of closure cap embody , which has to be mutilated in the opening of_ the ing the invention, but it is to be understood,`how- package in the first instance. Thus the closure ever. that this is presented merely for purpose is entirely incapacitated for re-application to the container in simulation of the original unopened 40 40 of illustration and that the invention may be availed of in other and modified forms Without condition of the package, although it may be con departing from the scope of the appended claims. tinued in use as an effective closure Afor the con In said drawing tainer. « Fig. l is an elevational view, partly in section, The nature of the invention will be more fully illustrating a closure cap adapted for use on a. ascertained from a. detailed understanding of the 45 bottle or the like; Fig. 2 is a bottom view of same; _ Fig. 3 is anA elevational view, partly in section, of la sealing cap'constituting an element of the structure illustrated inFig. l; Fig. 4 is a bottom view of a, holding member constituting'an element of the structure illus trated in Fig. l; ‘ Fig. 5 is a sectional elevation of the upper por tion of a package comprising a container with embodiment illustrated in the drawing,4 which will lnow be described. As seen in Fig. 1, the closure comprises a sheath member l0, a sealing closure I|._having a sleeve gasket I2 therein, and a holding member 50 i4. The sealing closure, which is illustrated in Fig. 3, comprises a cap or shell formedof a suit ably strong resilient sheet metal having an inte rior coating of a suitable lacquer or other mate rial -which will effectively resist the action of the 56 A 2,1 16,935 2 material which is to be packaged. This shell has a top pmel I5, which is domed upwardly in its central part, and a peripheral skirt or flange por tion depending from the top panel, the lower portion I6 of said skirt or ñange ñaring outwardly and the upper portion I1 belngsubstantially cy tion to an appropriate container, to form the lindrical or otherwise formed on a smaller diam a diameter somewhat smaller than the internal' diameter of the holding portion I1 and the flange eter than the flaring portion I6. The lower mar glnal portion of the skirt is turned inwardly to 10 form a, flange I8 which covers the lower edge of the gasket I2. The gasket I2 is of sleeve form and is made of a suitable soft but strongly elastic material, such as rubber. It is held under circumferential con striction or compression by the skirt of the shell, so that it conforms to the contour thereof in the The container 29, which may be a bottle or other suitable vessel, has at its mouth a rigid annular wall formed with a substantially cylin drical peripheral sealing surface 30 which is ofV I8 of the sealing closure and the lower margin of the gasket I2, but substantially larger than the 10 internal diameter of the balance of the constrict ’ed gasket I2. The container is also provided with a peripheral ledge 3| which is of a diameter such-as to ñt within the lower cylindrical portion 23 of the closure sheath. This ledge 3| is spaced 15 from the mouth rim of the container by a dis flaring portion IB, extending somewhat above the tance which slightly exceeds the depth of the seal lower limit ofthe holding portion I1 but having ing closure skirt. lts upper margin spaced from .the top panel I5. 'I'he sheath I0 is formed of a softer or more readily severable material such as light sheet aluminum. vIt is considerably deeper than the 25 complete' package. shell of the sealing closure I I and is of internal diameter such as to receive the same sn'ugly. It has a top portion 20 from which depends an an nular skirt, said skirt being formed with -flutes 2| which extend for theÍ greater portion of its depth from-the top portion, leaving the lower portion 23 in cylindrical form. The inwardly 30 offset portions of said flutes terminate at sloping surfaces 22'which are inclined inwardly and up wardly at the same angle as the flaring portion IG of the sealing closure. _ After the container has received its contents the-closure is placed upon its mouth, the mouth 20 rim entering slightly within the lowermost flaring portion of the gasket I2. Downward pressure is , then applied to the top of the closure, forcing it to seated positionl on the container, in which position the lower limit of thc sealing closure 25 shell is slightly above the ledge 3| and the top panel I5 is in contact with the mouth rim of the container, as seen in Fig. 5. In this forcing of the closure to seated position, the- pressure ap plied to the top of the sheath is transmitted di 30 rectly to the top of the sealing closure shell, and also, through the medium of the flutes 2|, to the flaring portion I 6 of the sealing closure shell. size such as to be received within the sheath I0, The downward movement of the closure relative to the container causes a wedging action to be 35 exerted upon the elastic gasket, causing it to be and is provided with projections 24 adapted to interengage with portions of the ñutes 2|, where by the member I4 is held against rotation within the sheath. Preliminary to insertion of the hold elongated upwardly along the holding portion I1 and placing it under high compression be tween said portion and the sealing surface 3l of the container. Thus a strong hermetic seal is 40 lng member into the sheath, a drop of solder 25 is applied to the central portion of its under surface. In assembling the closure from the parts above formed between the container and the closure. Such seating of the closure upon the container brings the lower margin of the sheath skirt to a described, the sheath is placed in >inverted posi and the lower portion of the sheath skirt is then 45 spun or flanged inwardly under the ledge, thus The holding member I4 is in the form of a ñat metal plate of generally circular outline and of tion, the holding member I4 is inserted into the sheath so that it comes to rest against the inner surface of the sheath top, and the sealing closure II is then inserted into the sheath until its domed top portion comes into contact with the drop of solder 25. Heat is then applied to the domed portion over the drop of solder, fusing the latter and soldering the sealing closure shell to the holding member I4. The sheath is then subjected to a punching or slotting operation by which portions of its skirt adjacent the marginal flange I8 of the. sealing position somewhat 'below the peripheral ledge 3|, locking the closure to the container. The pack age is thus hermetically sealed and cannot be opened without obvious mutilation. In order to open the package,. the narrow strands 28 are severed, as with a knife or other thin object, Since these strands occupy a posi tion between flange I8 and the ledge 3|, the sev ering of them is easily accomplished by inward pressure, and the severed margins are bent in wardly against the upper surface of the ledge 3| _ and the lower surface of the ñange I8, as seen closure shell are partially severed and bent in lin Fig. 6. After the strands 28 are severed, the wardly against and across said ñange I8, form package may be opened by giving the closure a (Ei) ing retaining elements 26 which serve to clamp rotary and upward movement. The removal the sealing closure securely and permanently in may be assisted, if need be, by prying upwardly ‘ the sheathing member, with the flaring portion on the flange I8, using the ledge 3| as a fulcrum I8 ln abutment with the sloping portions 22 and for the prying object. u the holding member I4 in abutment with the sheath top 20. After having been thus removed, the sealing 'I‘his forms in the skirt of the sheath a series4 'closure remains permanently'connected with the of apertures 21 running circumferentially thereof sheath, and may be re-applied by pressing it down at an appropriate distance above its lower mar gin. Said apertures are separated by narrow strands 28 of the sheath metal, which strands con stitute the sole remaining connection between the cylindrical lower portion of the sheath skirt and the ñuted upper portion in which the sealing closure is ipermanently secured. The closure is thus in condition for applica ' onto the mouth of the container, where the com pression of the gasket holds it securely in place. Re-application and subsequent removal of the closure are facilitated by giving it a rotary move ment, and this manipulation is facilitated by the depth and iluting of the sheath. In such opera tion the sealing closure is positively held against rotation in the sheath due to the interengagement 65 2,116,938 of the holding member I 4 with the flutes of the latter. ‘ - In the modiñed form of closure shown in Fig. 7 the sheath is designated generally by the refer ence numeral I0'. The sheath skirt is originally formed with two outside diameters, the upper portion of the sheath skirt being formed with the inwardly oifset ilutings 2l' as above described, and the lower portion originally being on a K10 larger radius as shown in dotted lines at 23' and being united with the upper portion by an annu 3 engaging the skirt of the sealing cap to retain the latter permanently in the sheath, said sheath skirt also being formed with inwardly oiïset flut ings extending from its top portion downwardly into overlying engagement with the outwardly extending portion of the cap skirt, the .lower portion of the sheath skirt being adapted to be telescoped onto and bent into retentive engage ment with a container, said lower portion of the sheath skirt being connected with the balance 10 thereof by narrow readily severable portions lar oiîset portion 3|. At its lower margin the skirt of thesealing cap is formed with an‘out wardly extending fold 32 of a diameter such as to 15 be received within the lower portion 23' of the spaced from one another circumferentially of the sheath. Ill aligns with the upper skirt portion Ila of the sealing cap, forming a strut through which down Ward pressure may be transmitted from the top of the sheath to the sealing cap.v The iiange l0 is provided with the outwardly extending pro jections 24' which engage between the flutingsv 2| of the sheath, for the purpose above described, narrow severable portions spaced from one an other circumferentially of the sheath, and a hold ing member iixedly connected with the sealing 2.

After the sealing cap has thus been positioned in the sheath, the lower portion 23' of the latter is bent inwardly under the outwardly extending fold 32 of the sealing cap to clamp the foldv against the offset portion 3i. The lower portion 23' of the sheath is retained in cylindrical form, as shown in the full line position in Fig. 7, and is a. punched at intervals, as above described, to form the retaining elements 26' which are bent inward ly into contact with the marginal flange I8’ of the sealing cap. Such punching forms the nar row severable elements as above described. This 0 modi?ed form of closure .is applied and añixed to the container as above described, and is operable for removal and re-application in the manner above described. ' ' What I claim js: 1.
