mann~r. E~ch c~ing l1 is made by folding a sheet o~
t.r~nspa~ent. plastie~ material to fo~m ~ re~t~n~ular box, and has in its top wall 9 a sl;t openin~ 15 which is to be formed by a user by piercing open a perforated line 16.

.
The roll 12 of ba~s 13 is foxmed by a continuous ~l~t plastics sleeve 17 h~vin~ a plurality of ~ran~verse se~l lines 18 at re~ul~r int~r~ls along its length. A
transvers~ lin~ of pe~for~tion~ l9 i~ provided i~ the sleeve l7 between adj~ent bag3 l3 olose to the cor~espo~ding seal line 18, there~y forming t~o distinct bags~ ~n other words, each seal line 18, exc~p~ the very last one inside th~ roll 12, i~ sccompanied by a corresponding per~or~ted line l9. It will be appreçi~ed that the se~l lines l$ and per~orated lines l9 define the closed and open ends of the bags 13, respec~i~e~y.

configuratio~.

The ~leeve l7 is pr~ided with a string 20 whi~ is placed withi~ the pleat ~lon~ o~e longitudinal edge, as ~ore cle~rly shown in Fi~u~e ~. The ~tring 20 i~ cu~ ~r partially sever~d in~o ~epa~ate len~ths by the perforate~

lines l9, and i~ ~ollecl up with the ~ ev~ 17 thereby being retained within the rc,ll 12.

I~ use, the outer end of the sleeve 17 is firstly pulled ouk tnrou~h the opening 1~ by a user until the first bag 13 is completely exposed so th~t it can be torn ~ fo~ uae.
It will be appreciate that the associated length of st~ing 20 is also retrieved at the s:ELme time with the b~Lg 13 and is then available f<:r la~er use for -tyin~ closed the open end of the bag 1~. Immedi~tely upon tearing off of the first bag 13, the end of the next bag 1~ is exposed out~ide the casing 11 th~ough the opes~ing 15 ready for ~uture u~3e.

Figure 3 is no~ also refe~ed to, which shows a di-Eferent sleeve 17A ~3uitable for replacing the e~rlier ~leeve 17.
Th~ sleeve 17A is folded c~nce lor~gitudinally about its 1~ centre lir~e to reduce its e~fect~ve width. The slee~e 17A
i~ no i: provided ~ith a separa~te strin but: instead an inte~ral ti~ 20A which is for~ed by one longitudix~al edge portion or strip 17A' o~ the E3leeve 17A. The adge portion ~ 7A ' is ~rranged to be torn away from the body of the ~ eve l7A ~long a perforat:ed ~ jne~ 21 imme~i;atel~ behind I . .
~hich the sleeve 17A is closed ~y a se~l line ~

As ic shown, the edge portion 17At ~nd the tie 20A are also partiaIly cut ~y trans~rerse perforated lines l9A in the slee~e 17A suc:h that ~he same length ~ill be torn off with an a~3~0ciated bag 13A from the ~;l~cve l~A. The tie 20A m~y ~ SlJlBSTlT~ S~E~

Th~ roll of bags 13A ~ormed by t~e sleeve 17A ~s llot only relstively simpler to manufacture ~u~ iLlso has the aàvant~e that the tie 20.4 does nc~t ;Ldd 8ny ~-hickne~;s to th~: roll and will ~ot get lost or mis-placed but ig imrnediately ~ ble for use when needed.

In either sle~ve 17 or 17A, the string 20 or tie 20A is roloured or has a oolo~r different ~om that of th~ sleeve 17 or the rest o~ the sleeve 17A for easy ldentification.

Refel~rin~ now to Fi~ure 4 which shows a box-like waste receptacle or bin ~O embodying the in~ention, the bag supply unit 10 i~ incorpQrated at the bottom. ~he first or ~ut.ermost bag 13 is opened up with its open end dispos~d S arou~d a ~im 31 o~ the ope~ top end of the bin 30 for receiving waste collected in the bin 30, At an appropriate time u~ually when the bag i~ ~ull, the bag 13 in us~ is lifted up from the bin 30 ~nd then torn of~ for disposal.
For h~gieni~ purpose or tidiness, the open end of the ba$
13 is to be tied ~losed before ~isposal. Xt will be appreciatsd that when o~e ~oll 12 of b~gs 13 is used up, an adj~cerl~ ~oll 12 may then be used.
