In Great Britain May 28, 1930 3 Claims. (Cl. 2220-65) This invention relates to. sanitary receptacles;

for dust and refuse and particularly to paper and/or fabric bags adapted to be inserted in such receptacles to receive the dust and refuse 8' and subsequently to be removed. from the recep-- tacles whilst closed upon their contents, and the invention has for its object to provide improved forms of bags for the purpose.

According to the present invention the im-, 10' proved bag which is adapted to be inserted as a lining in a domestic metal or other refuse receptacle or dustbin is formed, as a manua factured article ready for insertion intothe dustbin, with a bottom adapted to rest upon the bottom of the dustbin or upon a false bottom therein, with a tubular portion of substantiallyuniform cross-section and of length not greater than the internal height of the dustbin and essentially with a further tubular portion preferably at the upper end of the bag which portion is doubled-back or pleated or otherwise folded such that the upper edge of the bag will not normally project above the -dustbin' and will not be liable todamage, and'such that the 25, bag can be readily extended upwards or length ened to permit the closure and the sealing of the bag even if the dustbin be substantially completely full of dust or refuse.

In a modified form of bag which is otherwise the same as that above set forth, the extensibility is provided by the further portion being slit downwards in several places and reinforcing patches being provided at the lower ends of the slits to prevent them extending, such slit portion either being folded as above set forth or being left so that it can be folded outwardly downwards over the edge of the dustbin after insertion of the bag therein. In the latter case the fold may be protected from damage by means of a ring such as of metal which is adapted to be fitted upon the top of the dustbin.

The bag preferably consists of paper and/or fabric of one or more thicknesses impregnated so as to be waterproof or otherwise rendered substantially waterproof and preferably also impregnated with disinfectant if the waterproofing material is. not a disinfectant. No claim is herein made per se to waterproofing the bag or to impregnating it with a disinfectant.

The doubling back or pleating or folding of the upper portion of the bag to provide the extensibility may be of the accordian type but preferably comprises a fold outwards and downewards followed by a fold upwards, or a fold outwardsand downwards, a longer fold upwards, a further fold: inwards and downwards and finally a fold upwards. Alternatively the bag maybe formed with a single and relatively long fold inwards or outwards, and downwards.

The'bag may be made of flaring shape at the mouth to permit the doubling back or pleatingor folding aforesaid. Such flaring maybe produced for example by forming one or more slits and gumming, stitching, or otherwise applying insertions. '7

The invention also comprises the combination with a manufactured bagas above set forth of one or more fasteners secured in or near the upper end thereof whereby when the bag is extended it may be readily and quickly sealed by the dustman. Such a fastener may assume a variety of forms. In one form the fastener may be a spring or resilient clip or several spring clips secured to the edge of the bag, and adapted to close the latter when extended and the upper end folded over; such clip maybe, similar to the well known paper clip such as'that sometimes known as a slider or the pronged type adapted to perforate thepaperand be bent over. The clip may be secured to the bag by means of a pivotv or rivet. Such clip or clips may be so formed or arranged that they serve for supporting the bag within the dustbin such as by hooking over its edge, and also if desired for assisting in extending the upper end of the bag prior to closing it by means of said clips.

Alternatively the upper edge of the extensible portionof the bag may be eyeletted and. threaded with a string or wire or cord which may first be pulled for extending or lengthening the bag and then by further pulling used to bunch and close or seal the bag.

When av protecting ring is used as aforesaid it may have a relatively narrow'flange portion adapted to fit upon the top edge, of the dust- 10in, and a skirtv portion extending downwardly inside. or outside for instance a distance corresponding to the extensible portion of the bag. Such protecting ring may be split. at. one place or otherwise constructed so that it can be read ily applied to the dustbin.

To enable the invention to be clearly understood and carried into effect it will be described with reference to the accompanying drawing in Which Fig. 1 is a sectional elevation of a. dustbin showing therein one form of a'bag in accordance with the invention.

Fig. 2 is. a sectional elevation of one; of the no edge of a bag having secured thereto another form of fastening and Fig. '7 is a sectional elevation" of'a dustbinhaving a bag therein folded outwards over the V edge of the dustbin and protected against damage. Y

Referring to Fig. 1 of the drawing, 1 is the main portion of the dustbin and 2 the lid, and 3*is thelo'ag or liner which may be formed of material such as. hereinbefore set forth and which isprovided at its upper edge as indicated at 4- with a double fold arranged so that normally the upper edge of the bag does not pro-. ject at the upper edge of'the dustbin, but permits the bag to be extended beyond the edge of the dustbin and closed upon the-contents of the bag in any convenient -manner, such for example as by the means hereinafter described.

It willbe understood that instead of there being a double fold, as shown at 4. in Fig. 1, there may be only a single fold, extending q upon the outside of the bag such a distance as will permit the bag to be closed upon its contents after being extended. iThe extreme edge of the bag is preferably permanently folded,

as indicatedat 5, and .gummed or stitched or stapled.

In the modification shown at Fig. 2,,the upper edge of the bag is rendered extensible by being folded first; outwards and downwards as indicated at 6, then upwards as-indicated at 7, next inwards and downwards as indicated at 8, and then upwards as indicated at 9. The refuse, bag as above described'may be manufactured by'forming from a paper and/or fabric band of appropriate width, a substantially cylindrical tube or a tube of rectangular section, by securing 'the edges of said band with a substantially waterproof adhesive and/or with stitches or staples or other fastenin'gs of .wire or thread or the like, said tube towards its upper end being flared to permit of the provision of theaforesaid pleating or folding essentially necessary to enable the bag to be sufficiently protected against damage by the insertion into the bin of refuse and'the replacement of the lidof the bin,'whilst permitting-the bag to be subsequently elongated sufiiciently. to be properly olosedon its contents. Thus a'machine for mak ing such bags may be of a generally known kind comprising in combination means for feeding from a roll of paper and/or fabric of appropriate width to an approximately cylindrical or rectangular former or guide which" however is expanded .or. flared slightly at the delivery end for the-purpose above mentioned, with known means for mechanically gumrning. the adjaCenaedges tof rm the tube, and means forgcutting oif'lengths of tube sufiicie'nt to pro vide for the formation .firstly of. the bottom of the bag and. secondlyof the pleating or.fo1ding of the upper end to permit the extension thereof as aforesaid.

The closing of the bottom of the bag may be effected by forming slits and/0r folds of appropriate length and shape at the one end of the paper and/or fabric and then applying gum, cement or other adhesive and finally folding over against a mandrel so as to form the substantially fiatbottom to the bag, stitches of thread or wire or staples being used if necessary.

The pleating or folding of the top of the bag Imay be effected by a hand operation such as by the. use of a suitable jig as permitted by the flaring of the end of the paper cylinder.

The necessary pleating or folding may be effected when the paper and/or fabric coming from the roll is still in the flat or plane state, namely, by means of appropriately mutually moving folding or pleating members after whichthe paper is preferably subjected to a pressing or creasing operation such as between the feeding rollersor by other pressing means.

In the alternative method illustrated by Fig. 3

the flaring of the upperend-of thebag 3 may be effected by providing a plurality of longitudinal slits 10, for instance four slits and then flaring the bag, as clearly shown, by applying insertions 11 by gumming, stitching or otherwise. The invention also includes a bag having slits such as 10 (Fig. 3) without the insertions 11, provided the ends of the slits are prevented as shown in Fig. 3 from extending by tearing by means of reinforcing patches 12 of paper, fabric, canvas, or other convenient material, which may be applied by gumming, stitching or stapling for example.

I propose creosote as a convenient material for both waterproofing and disinfecting the paper but I do not limit myself to the use of creosote for the purpose.

Referring next to Figs. 4 and 5 of the accompanying drawing, one convenient form of clip 13 for closing the bag upon its contents after extension may comprise a wire 13 bent to the shape shown in Fig. 4, having downwardly extending clip portions 14 adapted to slide over the folded'upper edge of the bag as indicated at 15 in Fig. 5. The wire has extension 16 bent downwardly and terminating in an eye 1'7 which may be secured to the edge of the bag by means of an eyelet or rivet, so as to permit the wire clip 13 being turned upwards and then downwards again to secure the folded edge of the bag, The clip 13 may be engaged upon the edge of the dustbin to support the bag thereon.

Instead of the slider type of clip shown in Figs. 4 and 5, a clip of the pronged paper fastener type may be used, adapted to perforate the material of the bag and then be bent or spread outwards. Such arrangement is illustrated at Fig. 6, wherein the fastening clip comprises a strip of metal with pointed ends and bent to the shape clearly shown so as to have a head portion 18, retaining portions 19 and prong portions 20, the latter being bent as shown sideways until required for fastening the bag, when they may be bent outwards at right angles to the head 18, forcedthrough the opposite side ofthe bag and bent outwards oppositely to seal the bag.

Referring finally to Fig. 7, the upper end of the bag 3 may be formed as previously herein described, with simple longitudinal slits and then when inserted in the dustbin Said edges may bebentxoutwards around theupper edge of the bin, as shown at 21 in Fig. '7. The fold of the bag and the portion 21 thereof may be protected against damage by means of a protecting ring 22 comprising a portion adapted to fit upon the top edge of the dustbin and an external skirt portion 23 adapted to lie outside the dustbin. The ring 22 and outer portion 23 may be split as indicated at 24 to permit the ring to be readily applied to the dustbin, the ring being advantageously made resilient. In some cases, if desired, the ring 22 may be provided with an upstanding tongue (not shown) or the equivalent which may be used in a manner otherwise well known to permit the dustbin lid being tilted about said tongue or the equivalent, which acts as a fulcrum. In cases where the extensible portion of the bag is formed to be disposed within the bin, the skirt portion 23 of the ring may be arranged to extend inside the bin toprotect said extensible portion. Instead of the above described ring, a plurality of clips may be used distributed around the rim of the bin.

It will be understood that various modifications may be made without departing from the scope of the invention. Thus for example the bag may be constructed in the form of a tube and a separate bottom applied thereto and gumined and/0r stitched or stapled in position. 01' the bottom of the bag may be made of usual form, then blocked to the required shape on a mandrel or former, whilst gum or stitches or staples may be added if desired.

In order to prevent the bag being retained by suction in the bin, the latter may be formed with a plurality of holes such as indicated at 25 in Fig. 1, or alternatively, holes may be similarly provided in the bag itself.

An alternative way of closing the bag upon its contents may be by applying staples by means of a hand-operated stapling device which may be carried by the dustman.
