' Application filed November 1, 1921. Serial No. 512,154.

To all whom it may concern:

Be it known that I, ROBERT STANLEY Bnownfof 39, Victoria Street, London,\S. W., England, a subject of the King of Great 5 Britain and Ireland, have invented certain new. and useful Improvements in and Relating t Closures for Bottles, Tins, J ars, Containers, and Receptacles, of which the following is a specification.

' Wherever I herein use or refer to any of the four words: lid, lids, lids lids, I refer to and include any and all herein (as well as now) mentioned or described caps, lids, capsules, covers and the like and any of their kinds.

Wherever I herein use or refer to any of the four words: receptacle, receptacles, receptacles, receptacles, I refer to and include any and all herein (as well as now) mentioned or described bottles, tins, jars, containers and receptacles and any of their kinds.

Wherever I herein use or refer to any of the four words: rim, rims, rims, rims, I refer to and include any andall herein (as well as now) mentioned or described rims, dependent flanging, skirting, bands, or rim-like formations, and any of their kinds, whether integral. or non-integral with a lid, used in any suitable manner in one piece or suitably joined pieces, or interruptedly formed.

Wherever I herein use or refer to any of the four words: lock, locks, locks, locks, I refer to and include. any one (or any greater number) of any and all of the herein mentioned or described manners, forms types, and classes of rim provisions (and rim attachments and means) whereby a rim engages a receptacle (or its attachment or attachments) to obtain a hold thereon.

lVherever I herein use or refer to any of the four pairs'of conjointly used words: receptacles grip, receptacles grips, receptacles grips, receptacles grips, I refer to and include any one (or greater number) of any and all of the herein described, or stated receptacles portions or provisions for engaging the said lock or locks.

The invention relates to means for closing receptacles with a lid or cover provided with 'a rim whose locks are adapted to be applied to engage suitably disposed receptacles grips; sealing media, or medium, or

so formed that external pressure applied to' its periphery deforms it in a manner so as to cause its lock or looks to move substan-' tially disengagingly clear of the receptacle and thus become disengaged, and preferably for frequent. on and oil use, which use the invention obviously suits.

This invention mainly relates to rims, 0f innumerable shapings, being for example applicable to inkwells, pepperettes, holed lids, with or without hinging or like provision), in fact to any closure rim formation or flanging capable of use with a receptacle shaped externally in the immediate vicinity of its orifice in accordance with the requirements apparent from the following description, whether such vicinity be oval, round, rectangular, or other geometrical or irregular shape.

I use a receptacle. which has in one or more suitable positions any indentations or projections or shaping or provision which would obviously provide a receptacle grip (for rim locks) of the nature already herein set forth, as, for example, external grooving, flanging, beading, recessing, bosses, folds, seams, corrugations, false or full wiring, or combinations thereof, (roughened if desired), selected and shaped as suits. the receptacles construction or material.

' I may use any suitable sealing medium,

media, or packing in ring, disc, laminated,

or any other suita le form, shape, or cross section, whether loose, held by adhesion, or any other suitable means, in varying position, and whether placed, folded, cr'imped, seamed, or applied in plastic or fluid or solid condition into any suitable grooving or any other suitable position in (or on) the lid, rim, or (or as well as) the receptacle. For example I may use cork, fibre, paper, papier mach, though for most purposes I prefer to use dependably impervious material, such as rubber, balata, rubber compositions, impregnated cork (or paper), and dispose sealing media between the lid or rim and the receptacle.

Tocarry this invention into effect, a lid or rim is so shaped withrespect to its mating receptacle that when in an on position,

one or more clearancc portions of the rim in any suitable position and manner are caused to be sufficiently far away from the rcccptacles external periphery that external pressure applied to the rim in the neighbourhood of the said portion or portions (by hand or suitable appliance) can cause the rims material to yield inwardly with resulting alteration of the rims contour (as well as thereby unscaling a vacuum closure if so desired, as a. pronounced lifting action of the rim usually occurs). A dominant feature of this invention is that I practically ignore in lock design and the closures general arrangement the making of provision or allowance for such lifting action to occur thus obtaining a rim of customary economical depth though obviously I can and may make such provision and am aware of its releasing value with some forms of locks. The rim is made of suitably springy material, and with suflicient degree of continuity that. in consequence of the said inward yield, other portion or portions of the rims periphery will tend to recede from the receptacle; and the locality of these latter receding portions is where I arrange a rim lock or locks to engage with receptacles grip or grips, in order that the rims recession here may free such engagement to substantially a fully disengaged extent. To obtain these said clearance portions (or positions) I may use any suitable means, as for example :-all round rim edge clearance, by forming bulges outwardly (or inwardly or both) on the rim, or by providing the receptaclc with one or more recessed or raised portions where the rim covers it. The latter suitably disposed may restrain the rim from transit disturbances and assist in controlling the extent of the said recession -ac tion and more especially if such portions have vertical narrow channelling in which the rim edge rides (or nests).

I may therefore in some receptacles for preventing transit disturbances apply the rim so that it has to be rotated to reach its operative clearance position for release, or to meet one or moresuitably disposed receptacle excrescences intended to impart releasing pressure frictionally to the rims exterior clearance portion (or interior against the rim lock). AlternativelyI may use a guard rim having indents which on rotation of the guard rim similarly apply frictional rim releasing pressure.

Hereafter I use the following numbers as a reference to the features or conditions they indicate. This invention may be used for closures of (1) hermetic, (2) pressure resisting, (3) hermeticvacuum, (4) automatic vacuum types; each with (5) such regulatable automatically re-seating safety valve action as is desired; and by this inventions constructions and application method, excepting where I state otherwise, the foregoing five closures can (6) fulfil their duties without damage or permanent displacement of locks,

(7) have sealing (and rescaling) compression applied and retained to any desired degree, (and beyond atmospheric pressure).

(8) be re-applied in the true original, or a new, or more than one, ontposition on the receptacle, taking up variations in sealing media,

(9) optionallyentail initial destructible removal to prevent fraud,

(10) be instantly and frequently re-applied by springing on, and instantly removed by either pressing on or squeezing the rim at its clearance position (or positions),

(11) have the positions stated in clause (10) very closely defined and not diametrically opposite, thus assisting feature (14),

(12) ensure less risk than heretofore of receptacle damage when applying despite their usual inaccuracies,

(13) be applied without turning the lid, thus preventing disturbance or injury of sealing media,

(14) resist transit disturbance better than any known instantly removed and re-applied lid,

(15) be adapted to retain sealing media when a lid is removed,

(16) have exceptionally liberal amount of locking or pressure locking hold without interference With its on and off features,

(l7) automatically tend to draw the locks inwards as the internal receptacle pressure rises,

(18) "retain indefinitely cold pressures, and without structural alteration still relates (if so desired) identical pressures under high internal temperatures,

(19) automatically adapt itself to the many processing methods used for foods, and whether wholly or partially cooked in the receptacle after closing,

(20) be applied to most existing receptacles either with or without tools, or having to register the rim rotationably to the receptacle,

(21) be made in one press tool operation,

(22) fulfil such conditions as I mention economically, without deeper or thicker rims than is usual.

Four noticeable and ususual features which I have discovered and make use of in this invention (proved by my exhausivc tests and research) are (23) that rim release as described is not materially prejudiced by having to hold and meet the opposing reaction against such r'rlease of light or heavy compression of a seal- 111g medium directly interposed between the 11d (or run) and the receptacle,

(124) that such release as at (23) is possib e on both shallow and deep rims,

(25) that by numerous constructional variations I can control and direct, and augment, and graduate pressure of release and resulting movement of the locks, and in combination with (23-) and (24), and wlthout structed in. accordance with this invention ives a powerful closure, and with well de fined on positions or position.

I may use a rim (or lid) or receptacle of the kind having therein, or thereon, or attached thereto, any suitable of the innumerable obvious forms of suitabl disposed engagements or engaging mem ers (or provision) applicable to this invention (and its distortion manner of release) to serve respectively as looks or receptacles grips. Suchv suitable engagements (or. engaging members) could be for example of like types to the following :--snap on, snap in, indentations into recesses, pips, hooks, bosses, claws, shouldering types, thread or bayonet like, tongues and scallops; making no claim, however, to any of those known closures, combinations having thread-like engagement adapted solely to rotational removal. In further describing suitable locking arrangements I wish it to be understood the form of my proposed locks are in most instances of commonly known patterns, and further that it is not novel (in fact, proprietary) to provide for example, a rounded bead at the lower edge of a caps flange flattened at intervals to provide locking projections, as also to so curl a covers free edge as to lie enveloped within such coil and collapsing the latter at intervals to provide instruck looking projections, as also such enveloped edge construction in certain other combinations with locking projections and other indented constructions, as for example inventions such as fully described in specification Nos.

13,973/ and 1,079,238.

In order to collectively meet features hereinbefore numbered 1, 2, 3, 4, 5, 6, 7, 8, 10, 14, 18, 19, 22, 26, and in any combination,

' the design of the rims locks in combination atin or crim in or rou henin any suitgble o f these fear further trengt h or grip, and optionally (before or after or both before or after a receptacles processing or filling) employing rim denture tools toforce suitable of these dependable lock formations or suitable others at any desirable position (pre-formed if so desired) on or into engagement with one or more suitably disposed receptacles grips. Most of these de pendable locks embody feature 21. Another type of dependable lock I' prefer is an upturned internal rim edging, optionally crimped or corrugated.

A closure for features 4, 5, 6,18, '19 in this" invention is constructively proportioned as though the receptacles internal pressure was a load and the lid or rim the load support, whose span (lock spacing), strength, and stiffness have been scientifically proportioned by static considerations and conditions to get a recoverable specific deflection of the lid or rim between the locks to obtain pressure release 'under'such load with due compensation for (and consideration of) the following factors (when present) :the extent to which the sealing medium is compressed to allow for receptacle inaccuracies together with its initial and ultimate sealing compression desired; temperatures expansion efi'ects; processing time, temperature, and method; therecoverable yield, spring, and strength properties of the look.

I can obtain all the stated 26 features without having to necessarily resort tolid and rim strengthening or weakening formations of a nature now to be described, but such formations produce a closure incomparably better as regards features 2, 3, 4, 5, 6, 7, 11, 14, 16, 17, 18, 19, 22, 23, 24, and 26. Such formations are ones which locally and preferentially (or as well as generally) provide rigidity (or reduced rigidity) at varying portions of the lid or rim (or both). I may use any suitable such formations, as for example any suitable one or more or combination of the said dependable lock formations, (or recesses, dishings, holes, cuts, scallops). some obviously su table to a rim edge, others obviously applicable to any portion of a lids top, rim, or both.

Wherever I herein refer to strengthening or stiffening or weakening a rim, or lid, or lids-top, or rims edge for any purpose I may use any suitable of such formations in any number, and in any suitable manner, as these stated and other equivalent ones are used universally in the working of sheet metal for such purposes and in countless forms and combinations and variations such as :shape outlines, length, height, depth, position, contour, and in many direct ons such as:straight, waved, curved, spiral, angular, sinuous and combinations of these.

To better obtain features 4, 5, 17, 18, 19,

&

22, (complying if desired with feature 21) I may use any suitable lid top or rim strengthening or weakening formation as above described, a few of such being later described in the reference to the drawings herewith. Corrugating the rims periphery at the lock portions appreciably strengthens the rim at these parts, while scalloping or relieving or reducing the rims metal between the locks provides further yield at these latter places. Similarly, and for like features, corrugations or dishings may be suitably disposed on the lid top-to coact with the rim and rims formations.

In like manner as described in the last three paragraphs further use ismade of weakening and strengthening formations for perfecting features. 11, and 25 (and consequently features 10, 14, and 16). For example :--stifl'ening the clearance portions of the rim, makes them offer more resistance, and prevents permanent deflection of the rim (or its bulge) thus permitting of a small bulge with consequent metal saving, and more effective release. as when such portions are pressed inwardly their yield towards the centre line of the receptacle tends to lessen and the yield of the rim consequently tending to increase towards the locks. I further perfect these features (with still further economy of material) by directing the releasing motion (due to rim squeezing or pressure) definitely towards a speclfic direction (or lock) by strengthening locally those portions of the rim where I do not want the latter motion to occur (or' weakening the positions where I do, pr both of such means) one simple method being to use both long and short locks optionally combined with rim bulges which (preferably) gradually merge into the normal rims periphery at the short lock. Such constructions are exceptionally valuable when applied to slip lids and friction holding locks, since strengthening and weakening formations of the types described produce a strongly gripping slip lid which can deform appreciably without similarly de-' forming springy receptacles (thus avoiding a prejudicial clinging action), and further perfects this type of lid in features 10, 11, 13, 14, 15, 16, 20, 21, 22, 23, 24, (25 last section) and more so still when used with other means herein stated for preventing accidental disturbance.

For feature 14 rims may be made so difficult to release (or apply) as to require mechanical advantage appliances to supply the necessary releasing deformation pressure thereto, and I may use any such suitable appliances as may obviously be mounted on the rim, lid, or receptacle, as for example pivoted wire lever like formations.

By dishing a lids top, I may make my rims as deep as I choose, and consequently efiiciently apply the invention no matter how near the receptacles grip is to the level of the reeeptacles top.

To prevent accidental release, lateral rim play, and act as lid registers, I may further use shapes, indentations, bosses, or looks, or

any other suitable means on a lid (or rim) or receptacle or both, so shaped and disposed as would obviously meet these requirements, as for example :rim indents or locks touching a receptacles throat serve these three objects; external receptacle or rim protuberances can shield the rims clearance positions from blows; projection or locks thereon may be caused to too deeply engage the receptacle to be released by the external rims pressure deformation to act as transit locks for violent handling, or indicate tampering, such being freed by attached loops, or tongues, or prising outwards; spot soldering of the rim to a metallic receptacle or grip may be alternatively used, or such receptacle arranged to be initially pressed inwards at a lock posit-ion. External bulging on a lids top near a lock may be used to assist the deformation and initial release of a rim, as depressing such bulging causes outward movement of the rim (particularly scalloped rims), and if made non-recoverable to such depression and essentially having to coact with rim pressure for initially opening a closure it will indicate tampering, said bulging for protection being preferably less prominent vertically than other part or parts of the lids top, and obviously (if recoverably formed) may assist the lids application and removal.

Suitably placed rim indents or grooving or lid dishing may when desired also retain sealing media.

In releasing bulged and strengthened rims the operative rim release pressure applied to the rim clearance portions need not necessarily be applied normal thereto, but often even vertically thereto, and use may be made of many forms of rim pressing dies or channels to apply or release the stiffer order of rims.

I may use wire and skeleton like forms of rims in accordance with this invention, or lids having wire folded in or suitably attached thereto, in place of. but virtually fulfilling the described functions of the rim or its parts.

The rim or lid may be made of any suitable material, or materials, or any suitable combinations of materials, as for example iron, brass, tinplate, aluminium, duralumin. tagger sheet, carton like covers held by (or attached to) a metallic rim.

The lid and rim and receptacle are of any kind which is of a suitable shape or type to conform to the requirements of the invention, which requirements are readily understood from the description and drawings amines here provided, it being obvious that many unstated. innumerable combinations of my herein stated constructive features can be effected without departing from the spirit of this invention. This invention can obviously be used non-hermetically, or as a stopper retainer.

Locks and receptacles grips (or both) for features 7 and 8 may be placed or formed at varying level or series of levels in a-closure, the latter being also most adaptable to pierced or holed closures orifices which are throttled and opened without completely removing the closure, as for example closures which so operate on turning or partially withdrawing. In one closure I may vary the number, length, position, level, depth of engagement, size, type of locks, or receptacles grips (or both) often by such. means improving features such as 2, 4, 5, 6, 7, 9, 10, 11, 14, 16, 17, 18, 19, and 25, and for feature 5 sometimes employ one or more weak locks, intended to deform even non-recoverably.

Referring to the drawings filed herewith Figure 1, is a perspective view of one form of closure in accordance with this invention, shown partly in section.

Figure 2, is a perspective and part section view'of a form of the invention.

In all drawings, the locks are presumed to have been proportioned or spaced oommensurate with the pressure of sealing, rim strength, and extent of lid or rim yield for condition or feature 5.

Figure 1, shows a. sheet metal lid, the unseen side being of the same form as the side illustrated; the lock is beginning at k and extending round the rim edge to k", is slightly longer than the opposite lock is, and by being suffer and longer concentrates release motion towards o, the lock in having some recoverable yield for feature 5. d, p, g and to, m' are indents, the latter forming an auxiliary engagement. m'" and 'm' are cuts. d, d, j, m, n, p" and g and the embossed arrows and words are optionally raised or recessed metal. [2. is optional. The receptacles body is shown projecting be 0nd the closure for feature 14, and as a fu crum assists prising out of a lock. The remaining function of Z, Z, Z", Z" is already described. This closure suits features 1 to 26 inclusive, except 21 on account of the in dents. The separately marked grips on the receptacle are not screw threads, but reentrant flanging arranged in tiers.

Figure 2, is a cheap form of the invention applied to a circular tin, the lid being a circular blank, drawn down and half false wired all round! the rim edge, and flattened by press operation between the points w and w and w" and 'w and thus providing the clearance portions; the two unequal length locks being the un-fiattened parts of the half false wire. f is an externally and abruptly formed circular channelling made by, and during the same press operation which formed the internal all round false wireat e. h is a circular d-isc. This closure suits features :--1, 2, 3, 4, 5, 6, 7, (8 and latter part of 8 on suitable receptacle) 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, (20 partially) 21, 22, 23, 24, 25, and 26.

Figures 3 and 4 show a form of this invention applied to a beer bottle, the lid being a pressing dished concavely at t to compress it firmly on to es inner edge. The locks, for frequent on and off application and to withstand high internal receptacles pressure, have recessed or raised groovings at d. a The locks being V formed as shown and the V formation is flattened at and 26.

Figure 5, shows the invention applied to a square tin box, the locks being small false wiring, flattened at the clearance portions 8, 8' two opposite bulge formations on the rim Optionally the clearance portions may be obtained in like manner as illustrated and described for Figure 2, or to better obtain feature l t the bulge is made more pronounced and the false wiring only slightly flattened. h .in this casewas run into qs I grooving when fluid. The grips f, f being an all round internal channelling which may be optionally interrupted at the clearance portions .9, 8 This closure suits features as mentioned for Figure 2.

Figure 6, is a type of closure found su table for general use; A: and 7c are upturned rim edge locks preferably crimped as shown by the wavy dotted line. This closure can be made by one press operation and is suitable for features 1 to 26 inclusive (except 8).

Figure 7, shows a form of closure in accordance with this invention, in which it is disposed on the side of the receptacle bedding on the formation t. k and is being large three quarter false wiring, off set as shown, and of the lengths indicated by the arrows. The clearance portions 8, s are obtained by the shaping of the cut blank so that the false wiring is only barely half formed at these port1ons,-as shown at 2, k, and is being by their liberal formation and off set, springy and of a recoverably yielding nature.

Figure 8 is a closure generally as in Fig- ,ure 6 but with the metal removed at the clearance portions 8 s and a pivoted wire loop substituted as shown. To receive the wires ends, the locks in and k are full false wires. To release the closure the loops are brought down to the dotted position and pressed inwards at 7", r'. The bottle projection :29 on either side of a is formed so that the wires 3 and y when brought down can snap over an and thus function as the well known processing clips for automatic vacuum closures. In further reference to Figures 2 and 5 the flattening of the upturned rim edge is not my manner of providing the locking projections. these being already provided before flattening takes place, but on the contrary said flattening is to provide clearances and to eradicate unrequired already formed locking projections, overformed merely for the convenience of employing circular initial sheet metal blanks.

Reference to all figures will show that sufficient squeezing of the rim edge at the two clearance positions substantially frees both locks simultaneously. 1 point this out specially because the arrow lines in the direction '0 might show an intent to merely free but one lock, whereas, as previously stated features 11 and 16 are features which are being improved by the unequal length of locks illustrated.
