Description
BACKGROUND
This invention relates to an improved multiple-article carrier.
More particularly, this invention relates to a multiple-article
carrier of the crown-support variety.
Crown-support carriers, of the type shown in U.S. Pat. No.
3,156,358 which was granted Nov. 10, 1964 to B. F. Randrup, are
known in the prior art. These prior art carriers have not, however,
been widely accepted in the industry, principally because they are
not sufficiently rigid for use with the several article sizes
presently on the market and because they do not afford maximum
protection to the articles without the use of additional protective
device such as the netlike sleeves disclosed in the above cited
patent. In this regard, it should be noted that articles carried in
the prior art crown-support type carriers are subject to a rotation
in a lateral plane which causes contact at or near the bottoms
thereof. Moreover, the prior art carriers do not afford maximum
protection against crown damage and pilferage or inherent loss
therefrom since a portion of the crown is exposed in all such
carriers. Further, the prior art carriers have employed a
single-ply handle which is inherently weak, as is readily
apparent.
BRIEF DESCRIPTION OF THE INVENTION
Accordingly, it is an object of this invention to provide an
improved multiple-article carrier of the crown-support type.
Another object of this invention is to provide a multiple-article
carrier which can be prepared from a single blank of sheet
material. Still another object of this invention is to provide a
multiple-article carrier which will lend itself to high-speed
packaging operations. Yet another object of this invention is to
provide a multiple-article carrier of the crown-support type having
improved strength and rigidity. A still further object of this
invention is to provide a multiple-article carrier of the
crown-support type which affords increased protection to the
article crowns. Yet a further object of this invention is to
provide a multiple-article carrier of the crown-support type having
a handle section of increased strength. These and other objects and
advantages will be apparent from the description hereinafter set
forth and the accompanying drawings.
In accordance with the present invention, the foregoing, and other
objects, are accomplished with a carrier which may be erected from
a single sheet of blank material and comprising an article-support
panel having means associated therewith for securing said carrier
to the carried articles, and a top panel, which top panel has means
associated therewith for carrying the erected carrier. The carrier
is most conveniently erected by first securing the support panel to
the articles to be packaged in said carrier and then folding the
top panel into position and securing the carrier as erected. As
will be apparent from the discussion hereinafter, the carrier also
comprises side panels, means for securing the support panel in
place and means for securing the carrier in an erected
configuration.

DETAILED DESCRIPTION
Referring now to FIG. 1, there is shown a unitary sheet of blank
material which is cut and scored so as to define the bounds of the
various panels and other elements on a carrier within the scope of
the present invention. The blank may be prepared from paper,
paperboard, polymeric and other similar materials. The blank, as
shown, comprises two article support panels, 1 and 1', which panels
are disposed on opposite sides of the blank and fashioned in a
manner such that each will support a single row of carried
articles. Each of said article support panels, 1 and 1', have,
pivotally attached thereto, sidewall wall panels, 2 and 2', along
longitudinal scored fold lines, 3 and 3', respectively, and
elevation panels, 4 and 4', along longitudinal scored fold lines, 5
and 5'. As can be seen in the Figure, the sidewall panels are
disposed along the outer edge of said article support panels
whereas the elevation panels are disposed along the inner edge of
said support panels. The elevation panels, 4 and 4', are pivotally
connected to securing panel, 6, respectively, along scored fold
lines, 7 and 7' which securing panel is disposed between said
elevation panels. The sidewall panels, 2 and 2', are pivotally
connected to top panels, 8 and 8', along longitudinally extending
scored fold lines, 9 and 9', respectively.
Article-support panels, 1 and 1', comprise means, 10 and 10', for
securing said support panels to the articles which are packaged in
the carrier of the present invention. As shown, means, 10 and 10',
comprise apertures, 11--11 and 11'--11', which apertures define the
inner boundaries of a series of small, adjacent panels, 12--12 and
13-- 13, respectively. The small, adjacent panels, 12--12 and 13--
13, are further defined, respectively, by starburst cuts, 14--14
and 15--15, and scored fold lines, 16--16 and 17--17, which,
respectively, define the outer boundaries of panels, 12--12 and
13--13. For convenience, the combination of cut and scored lines
which define apertures, 11--11 and 11'--11', and adjacent panels,
12--12 and 13--13, will be referred, herein, as starburst
apertures. It will be appreciated, that although the starburst
apertures, as illustrated, are surrounded by six adjacent panels,
the term as defined is intended to include any number of panels
which may or may not be of uniform size. For example, the number of
panels could easily be reduced to four or increases to 12.
Moreover, the term as herein defined is intended to include
arrangements wherein the various panels are not adjacent in the
blank layout.
The securing panel, 6, is cut and scored so as to define apertures,
18--18, securing tabs, 19--19 and 19'--19', and apertures, 20--20.
Apertures, 18--18, cooperate with apertures and top panels, 8 and
8', to afford means for lifting the carrier when erected. Securing
tabs, 19--19 and 19'--19', are fashioned such that they will rest
atop the article crowns when the carrier is formed into a package
and thereby afford additional support to the securing panel, 6.
Apertures, 20-20, are fashioned so as to receive locking tabs and
cooperate therewith to hold the carrier in an erected position. It
should be noted, that cut lines 21--21 and 21'--21', which define
the outer boundaries of securing tabs, 19--19 and 19'--19', also
define a locking edge in elevation panels, 4 and 4', which edges
may be secured under the crowns of carried articles to afford yet
further support for the securing panel, 6. The top panels, 8 and
8', are cut and scored to define carrier tabs, 22--22 and 22'--22',
which are pivotally connected to said top panels along scored fold
lines, 23--23 and 23'--23', respectively. As will be readily
apparent, the carrier tabs, 22--22 and 22'--22', can be rotated
downwardly through apertures, 18--18, and secured below securing
panel, 6, to afford added rigidity to the handle section when the
carrier is erected and to prevent contact with the raw edges when
the erected carrier is carried. To panel, 8, also is cut to define
locking tabs, 24--24, which tabs are free to pivot about scored
fold lines, 25--25. The locking tabs, 24--24, pass through
apertures, 26--26, which are cut in top panel, 8', and are secured
below the boundaries of apertures, 20--20, to hold the carrier in
an erected position. It will be appreciated, that locking tabs,
24--24, could be secured by the boundaries of apertures, 26--26,
but the carrier thus obtained would not be as rigid as that
obtained by securing these tabs below apertures, 20--20.
In order to better understand the present invention, reference is
now made to FIG. 2, which is a perspective view of a package
embracing said invention. As can be seen in FIG. 2, the blank as
shown in FIG. 1 has been used to package six articles, 27--27. As
can best be been in FIG. 5, the support panels, 1 and 1', are
positioned below the crowns, 28--28 and 29--29, a distance
sufficiently below said crowns so as to enable the inner edges of
the adjacent panels, 12--12 and 13--13, which are defined by
starburst cuts, to engage under said crowns. As can then be seen in
FIG. 2, the side panels, 2 and 2', extend upwardly from said
support panels and are substantially perpendicular thereto when the
carrier is fully erected. The elevation panels, 4 and 4', also
extend upwardly from the article-support panels, 1 and 1', but as
can be seen in the Figure, the elevation panels, 4 and 4', , lie in
a plane which, if extended, would intersect with the plane defined
by the side panels, 2 and 2', so as to enable the locking edges
formed by cut lines, 21--21 and 21'--21', to engage below the
crowns, 28--28 and 29--29 (not shown). Top panel, 8', extends
inwardly from said panel, 2', and lies in a plane substantially
parallel with that formed by support panels, 1 and 1', and overlaps
securing panel, 6. Similarly, top panel, 8, extends inwardly from
side panel, 2, and lies in a plane substantially parallel with that
defined by support panels, 1 and 1', and overlaps securing panel,
6, and a portion of top panel, 8'. As can be seen in the Figure,
locking tabs, 24--24, extend downwardly through apertures, 26--26,
and apertures, 20--20, and are secured there below to hold the
carrier in an erected position. Similarly, carrier tabs, 22--22,
(and 22'--22', not shown) extend downwardly through apertures,
18--18, and are secured below support panel, 6, and thereby afford
additional rigidity to the handle section. It should be noted, that
that portion of the carrier in which the means for carrying same
are provided is three-ply throughout, said three plies comprising
securing panel, 6, and the overlapping portions of top panels, 8
and 8'.
To further illustrate the present invention, reference is now made
to FIGS. 3-5, which show partial end views of a package prepared
with the carrier of the present invention at various stages of
erection of article carrier. FIG. 3 shows the position of
article-support panels, 1 and 1', after said panels have been
forced over the crowns, 28--28 and 29--29, with said crowns
protruding through apertures, 11--11 and 11'--11'. Also as shown in
FIG. 3, the elevation panels, 4 and 4', have been rotated about
scored fold lines, 5 and 5', and extended upwardly and secured in
their finally erected positions. In this regard, it should be noted
that the locking edges created by cut lines, 21--21 and 21'--21',
are positioned below the crowns, 28--28 and 29--29, such that a
portion of said crowns extend through the apertures created by
securing tabs, 19--19 and 19'--19'. It will be appreciated, that
these locking edges as thus positioned will prevent securing panel,
6, from moving upwardly when the carrier is lifted. As can also be
seen in FIG. 3, securing tabs, 19--19 and 19'--9', extend over the
crowns, 28--28 and 29--29. As positioned, these tabs reduce the
tendency of securing panel, 6, to move downwardly when locking
tabs, 24--24 (not shown) and carrier panels, 22--22 and 22'--22',
are secured in the locked position. It should be noted that
elevation panels, 4 and 4', extend upwardly from article-support
panels, 1 and 1', at an angle less than 90.degree. therewith to
enable the edges formed by cut lines, 21--21 and 21'--21', to lock
beneath the inner edges or crowns, 28--28 and 29--29. It will be
appreciated, that a useful carrier could be constructed by allowing
the elevation panels, 4 and 4', to extend upwardly in a plane
substantially perpendicular with that containing the
article-support panels, 1 and 1', but such a carrier would be less
rigid. Similarly, securing tabs, 19--19 and 19'--19', could be
omitted, but some handle and stacking strength would be sacrificed
thereby. With the article-supported panels, 1 and 1', and the
elevation panels, 4 and 4', positioned as shown in FIG. 3, it is
then possible to rotate side panels, 2 and 2', respectively, about
scored fold lines, 3 and 3', and at the same time to rotate top
panels, 8 and 8', about scored fold lines, 9 and 9', in the manner
shown.
Top panel, 8', can then be moved to its erected position as shown
in FIG. 4. The top panel, 8', may be held in this position by
inserting carrier tabs, 22'--22', through apertures, 18--18 (not
shown), and top panel, 8, then rotated and secured in position as
shown in FIG. 5. It should be noted, that top panel, 8, is held in
place, principally, by rotating locking tabs, 24--24, downwardly
through apertures, 26--26 and 20--20, and securing same below
securing panel, 6. This locking procedure will be reinforced by
rotating carrier tabs, 22--22, downwardly through apertures,
18--18, and securing same below securing panel, 6. It will be
appreciated, that when the assembled package is lifted, carrier
tabs, 22--22 and 22'--22', will be rotated inwardly and will
prevent direct contact with raw edges of carrier material.
In general, the multiple-article carrier of the present invention
may be used to package any number of articles, it will be
appreciated, however, that for practical reasons, the carrier of
the present invention will be most suited for the packaging of from
two to about 12 articles. Moreover, it should be noted that
although the carrier of the present invention has been illustrated
by reference to a carrier designed for packaging six articles in a
two by three arrangement, the carrier of the present invention
could, through only slight modification, be made suitable for use
with a single row of articles or with more than two rows of
articles. For example, it is contemplate that the carrier, as
illustrated, could be easily modified to facilitate packaging of 12
articles in a four by three arrangement.
Further, the carrier of the present invention may be used to
package any article having a crown or other projection which
extends outwardly from the article a sufficient distance to enable
the panels to be secured in the manner herein described. In this
regard, it should be noted that the carrier of the present
invention could be used to package any articles having a protrusion
in the upper portion thereof; e.g., a neck flange, which extends
outwardly from said articles a sufficient distance to permit the
various panels to be locked in a manner herein described. Moreover,
it should be noted that the article-support panels of the carrier
of the present invention could be positioned prior to placing the
crown on said articles. Further, it should be noted that
substantially any method, known in the prior art, could be used to
lock the carrier in an erected position. In this regard, it should
be noted that the method of locking, as herein described and
illustrated, is, however, particularly preferred.
PREFERRED EMBODIMENT
In a preferred embodiment of the present invention, the blank as
shown in FIG. 1, is cut from paperboard. The carrier is used to
package six or eight containers such as those described in U.S.
Pat. No. 3,372,826, which issued to Richard A. Heaton on Mar. 12,
1966, which containers comprise an upper portion of glass and a
lower portion of a less frangible material, such as low or medium
molecular weight polyethylene. Packaging in a two by three or two
by four arrangement is preferred and packaging in a two by three
arrangement is particularly preferred. Further, in a preferred
embodiment of the present invention, the carrier will comprise
locking tabs such as those illustrated in FIGS. 1-5 and designated,
24--24 and 22--22. Moreover, the carrier will comprise securing
tabs such as those shown FIGS. 1-5 and designed as 19--19 and
19'--19'and the elevation panels, 4 and 4', will be fashioned with
locking edges which will engage below the inner edges of the
crowns, 28--28 and 29--29.
Although the present invention has been described and illustrated
by reference to particular embodiments, it will be readily apparent
that the present invention lends itself to various modifications
which will be obvious to those skilled in the art. Accordingly,
reference should be made solely to the appended claims to determine
the scope the invention.
