aperture section as described previously. However, as also
shown in FIG. 8 such aperture section 5-7 at a point spaced
-from the margin of top intermediate panel 19 is of a 15
somewhat smaller dimension than the upper diameter
of the closure cap. This results in a container cap being
inserted through such aperture section with a secure snap
ping action which may temporarily deform part of the car
rier extension panel 44 or 46. However, because the 20
carrier desirably is formed from paperboard or like
?exible material no damage thereto is done thereby. Fol~
lowing insertion of a carrier cap through an enlarged aper
ture section 57, the bottle neck 4 is snugly and securely
engaged in the smaller aperture section 56 as shown in 25
FIGS. 9 and 11.
When a top extension panel is pivoted downwardly to
the closed position, sufficient clearance exists in each en
larged aperture section 57 so that such panel may clear
the respective container closure caps and be moved to
the solid line position shown to the right of FIGS. 8 and
9 in which such panel is snugly engaged with the down
wardly and outwardly sloping shoulder 3 of each con
tainer positioned in the carrier. This engagement of an
extension panel with the container shoulder 3 is of a very 35
secure nature which may result in some outward bowing
of the extension panel as seen in FIG. 10. Such a condi
tion is desirable in that it urges the container fully into
the carrier and insures snug engagement of the container
40
neck in aperture section 56.
As FIGS. 8, 1-0 and 11 illustrate, the lower peripheral
edge 11 of each container cap is directly engaged with the
top surface of top intermediate panel 19. As a result
of such direct engagement, when a carrier is picked up by
a consumer inserting his ?ngers through the carrying holes 45 .
provided by top tabs 61 and 62, the direct engagement of
the container caps with the carrier top results in a sub
stantial portion of the weight of the respective bottles being
borne directly by the carrier top. That is, all of the
container weight is not supported solely by the carrier
bottom as is true of many prior art carrier constructions.
As a result of the novel arrangement described, dropping
of bottles during handling should the carrier bottom be
weakened by moisture or the like is precluded because of
the secure engagement of the container vcaps with the car 55
rier top intermediate panel 19.
A further advantage of the direct engagement of the
container caps 6 with the carrier top is illustrated by
reference to FIG. 7. From this ?gure it should be noted
that because no'portion of the inner periphery of the
lower edges of the respective container caps 6 projects
above the carrier top, a person’s ?ngers may not be in
serted therebeneath or scratched thereby when ?ngers are
engaged with the carrying holes provided by top tabs 61
65
and 62.
From the foregoing it should be understood that the
subject invention involves the provision of a novel con
tainer carrier which is usable to provide a particular pack
age constmction well adapted for enclosing a quantity
of containers. The invention also involves the novel 70
method of setting up and ?lling such a carrier with con
tainers in the expeditious manner heretofore described.
While the subject carrier is intended primarily for the
packaging of beverages such as beer or soft drinks, ob
viously containers ?lled with other products could be 75
