be~een tab3 31, 32 remain~, thus provisling a handle by w~ich ~he
carton ~an be grasped. 'rhi8 ~eature allc~ he carton lt~ be u3ed
for returning empty beverage contaislers.
Referring now to Figures 3 of the drawings there i3 ~ha~
10 a blank la of paperboard or similar foldable ~heet ma~erial in
which like part6 of Figure 1 are de~ignated liXe reference
numerals but with the addition of ~uffix 'a".
The ~nain ~truc ural difference bet:ween ~e carton 'C' of thi8
embodiment and that previously ae~cribed iB ~hat opening~ are
15 provided in each top ~orner of the cartorl (aee Figure 4) ~o that
the contents of 'che carton can be ~een. To achieve lthis feature
the apertures l9a, ~Oa of blas~k la are enlarged as compared with
apertures 19, 20 of blank 1. The aperture l9a ~ut~ in~o panel 3a,

~truction ansl iB ~lo~ed in a ~ashion similar to ~ a0E~cribed
~bove., ~oxeover, it i~ envi~aged that top panel 4a may be

d~3~ribed in relation to carton 'C'.
Referring r~ow to Figure 5 of th~ arawings there i~ shawn
a blan}c lb of paperboard or E~imilar foldabl~ ~heet material in
which like part~ o~ Figure 1 are designated li3ce xeference
10 numerals but with the addition of su~fix "b". The layout of
blank lb also i8 different to that oiE blanks 1 and la previously
.
de~cribe~ in that a part of one ~ide wall panel 5~ hown
inteyral with top wall panel 4b and the rernaining part of side
wall panel 5b is sh~wn integral wit:h bottom wall panel 2b. The
15 effeet of thi~ layout i~ that both the ~ide flap panel~ 15b, 16b
depend from the bottom wall panel prior to glu~3ing the blanX into
its ~leeve_like confiyuration. Thi~ i8 nece~ary . ince ~he
carton of thi~ embodiment i8 not provided wi~h a top wall end
closure panel as in the previous embodime23t~.
H~wever, the carton 'C2 ' ~ a~sembl~d in a ~imilar
ashioII in that fir~t tl e blahk lb i8 bxought into a sleeve-like
~:or~figura~ion by bonding the glue ~rip portiorl 9b of side wall
panel 5b in overlapping relation~hip wi~ the oppo~ite part o~

~ide wall pan~l 5b. After ~he ~arton ~as been end- loaded with
~5 containers as previou31y referred to ~e carton end~ are ~losed.
In the example shown, lthe end flap panels 15b, 16b zlre folded
inwardly acroRs the open end of the eleeve ~bou'c t~eir re3pec-
tive fold line~ 17b, lBbo Thi~ ~olding operat~on cau~es the

provided betw0en ~ottom ~nd clo~ure p~nel llb and each of end
flap panel~ 15b ~nd 16b re~pectively. ~he tuck-in flap 35
will old fl~t ~gain0t the inside face c~f ~s3ttom ~nd closure
panel llb by folaing ~bout oblique ~old line~ 37, 3B ~nd

q~o complete the end clcsure ( ~ee Figure 6~, olding of
the bottom end closure pane~ llb i~ continued ~o a~ to bring it
10 into oYerlapping relation~hip wi~ the end flap panels l5b, 16b
and ~ecure~ ther to. It will be appreciated that the oppo~ite
end of the carrier i.~. bel~w cel~tre line "L-L" iB of ~imilar
c:onqtruction and i~ clo3ed in a fashion ~imilar to that ~u~t
described-. Thu8, the carton end~ are ~losed only at the bottom
15 Election ~o that ~he contents of the carrier ~an be viewed
through the open top portions of the end ~lo~ure~ as best seen
in Figure 6 of the drawings.
The tightneQs of the carton structure wi~h respect to lts
content~ i~ achieved in a manner ~ ilar to that previou~ly
20 described in that ea~h gUQBet panel has side edge~ w~ich are
divergent in a direction away fr~m the bottom panel 2b up to
the point of $nter~e~tion wit~ central ~san Yer8e fold line
28b, 28b' whereafter the gU8Eet panel ~ide edges are convergent
towards the top mo t edges of the respect~ve end flap panel~.
An ade~uate degree of tightne~s i8 par~ieularly important
with regard to the Qarton 'C2' of 'chis embodi~en~ ~n ~hat the
esAd structure i~ part~ally open ~o that ~ecuro retention of 'çhe
beverage container~ i~ de~irable to prevent aceidental
lodg~nent or pilf~rag~.
