Abstract
ABSTRACT OF THE DISCLOSURE
A stackable package for protecting edible food product contents is formed by a flexible bag attached inside a relatively rigid box. The box is open on only one side, through which extends a reclosable end of the flexible bag. The reclosable end begins to taper just above the open box edge, so that the box does not impede opening. The package, when placed on its side, is stackable in that it can support other boxes on a side opposing that side upon which the box rests. The flexible bag may be foil-lined to act as a moisture barrier to protect fresh-ness.

There 1~ no dlsclosure, however, of an lnner bag attached only at the upper contalner lnterlor walls, nor ls there disclosure of a contalner having a relatlvely rlgld bottom.
SUMMARY OF THE INVENTION
It is accordingly one object o~ the present lnventlon to provlde an lmproved package which ls lnexpenslve to rabrlcate, requires no extraordlnary equlpment in the fabrlcation thereof, and that ls formed of readlly avallable materlals that can be manufactured by persons skllled ln the package art.
Another ob~ect of the inventlon ls to provide an improved package whlch can be easlly ~tacked on A supermarket shelf eo . . .
a~ to conserve valuable ~rocer shelf space.
Another ob~ect of the present lnventlon ls to provlde an improved package whlch can be shlpped ln flat or folded con-l dltion, and whlch can be fllled wlth bakery products, cookles, ; crackers or the llke.
A ~urther ob~ect Or the present lnventlon ls to provlde an improved packa~e which lncludes a fastenlng means located be-tween an lnner flexlble bag and an outer, relatlvely rlgldl caslng whlch 18 economlcal tQ apply and whlch ls so located as ~24SS~g to be inconspicuous during normal usage by the ultimate consumer.
A still further object of the present invention is to provide an improved package having a relatively flexible bag-like member retained within and supported by a relatively rigid outer box member so as to permit stacking of the container in vertical columns on a grocer's shelE, within larger shipping containers, or within a purchaser's cupboard.
Another further object of the present invention is to provide an improved container formed of a flexible bag member attached by only a single attaching point within a relatively rigid outer container so that ease of assembly results as well as economy of production.
A still further object of the present invention is to provide an improved package having a box-like, relatively rigid member which can be folded from a blank and which can receive and be attached to a flexible bag-like member for the support of frangible, fragile food products such as crackers, laminated cookies, and the like.
The invention is directed to a stackable soft-top package having a rigid container with a flexible bag located therein, said container and said bag having adjacent sealed ends, characterized in that the rigid container has an open end opposite said sealed end and said bag has a recloseable end opposite said sealed end, wherein said recloseable end of said bag extends beyond said open end of said container, said bag tapering from said open end of said container to said recloseable end of said bag, whereby opening and closing of the bag is not impeded by the container, said package being further ~29~S5~9 characterized in that said bag is permanently Eixed to said container by an adhesive material connecting a portion of an outer surface of said bag to an inner surface of said container.

DETAILED DESC~IPTION OF THE INVENTION
A stackable, soft-top package 1~ shown in perspectlve ln flgure 1. As can be seen, a flexlble bag havlng a front slde lO is retalned wlthln a relatlvely rlgld contalner having up-standlng slde walls. A label 5 19 shown attached to the front wall 8 of the box member. The lower box member ls formed o~
sheet material whlch may comprlse any of the usual or preferred contalner-formlng materlal~, but preferably may comprlse a sheet o~ cardboard, stlf~ paper, plastlc, or other relatlvely strong sheet materials and the lnner bag structure may be con-structed of relatlvely flexlble materlals used ln the food product packaglng art, such as a lamlnated foll-paper ~tructure for preservlng fre~hnes3. However, any materlals may be used havlng the requlred relative stlffness or flexlblllty. For ex-ample, the bag~ may be formed of cellophane, flexlble plastlc, brown paper, paper, wlre mesh, foll, cloth, or any other flex-lble materlal.
The box member may be constructed of cardboard ln a pre-rerred embodlment; however, any other packaglng materlal may be used that 1~ surflclently ~strong to permlt stacklng of the con-talner~ ln a vertlcal colum~. For example, the followlng ma-~z~s~
terlals may advantageously be used for the box member materl-als: stifr cardboard, plastlc, ~heet plastlc having llving hinges to serve to connect the sldes, ~heet metal, wood, foamed plastlc, and the llke. The bag-like member tapers ~ust above the box-llke member, ~o that opening Or the bag-like member 18 not lmpeded by the box-like member.
The box member ls formed by lert-hand ~lde wall 2, front wall 8, rlght-hand slde wall 7, rear wall 13j and bottom 6.
The box memb~er may be formed by foldlng from a blank, moldlng operatlons, or the llke. A label 5 may be attached to any surface, or plural labels may be applied to a plurallty of ~urraces Or the box member. If the box member has been formed from a blank, the bottom 6 wlll be composed of glued or other-wise sealed flap members a~ shown ln r1 gure 8. The box member need not have the up~tanding walls arranged ln a rectangular cross-section, but may be formed lnto any conflguratlon o~
wall~ havlng at least two parallel space opposlng walls such as a hexa~on, octagon, or the llke. In any case, the bag-like member tapers ~ust above the box-llke member, 80 that opening of the bag-llke member is not lmpeded by the box-like member.
Flgure 2 shows a front vlew Or the contalner of the pres-ent lnventlon. The front wall of the bag member ls shown wlth only the top portlon vlsible above openlng 9 Or the box member.

Fold 15 is at-tached to reclosable end portion 4 of the bag member and serves to ~ubstantially prevent passage of gas, alr, or vapor throu~h the opening o~ the bag member and is conventlonal in the bag package art. Adheslve 16 ls shown ln dotted outllne, and se-cures side 14 of the bag member to rear wall 13 of the box member.
Flgure 4 shows the rear of the container of the present i lnventlon, and clearly shows deformable bag fastener elements 12 at each slde of the reclosable end portlon 4 of the bag mem-ber. The deformable bag fastener el-ements 12 are well-known in the art, and may be formed of lamlnated plastlc or paper havlng two reinforcing wlres wlthln for closing and openlng the bag member and retalnlng the ~olded over portlon 4,5 ln closed po-sltlon. The adheslve, which may be anlmal glue, hot melt adheslve, wood glue, rubber cement, pressure-sensltlve adhe~lve, or any adheslve or bonding materlal or element sultable for the materials used, ls shown ln dotted outllne as adheslve 16 ln flgure 4. The shape of the adheslve 16 formlng a bond or connectlon between the rear slde 14 of the bag member and the rear wall 13 of the box member need not be of clrcular or oval shape, but may be of any shape or cluster Or smaller bonds that ls economical to apply and yet retalns the ba~
member wall agalnst the adjacent box member wall. Here al~o, the bag member ls shown both ln upper solld outllne and lower dotted outllne for clarlty.
Fig~re 5 is an enlarged, partlal sectlonal vlew of the adheslve Joint formed betwee~ the bag member and the box mem-~Z~55~7~
ber. Box wall 13 ls shown ln cros~-sectlon rlxedly attached by adheslve 16 shown ln cro~s-sectlon to bag wall 14, also shown ln cross-sectlon. The thlckness of adheslve 16 18 exaggerated ln Figure 5 ~or clarlty. The lnterlor wall of the bag member is seen ln thls ~igure, as well as the lnterior portlon of rlght slde wall 7 of the box member.
Flgure 6 i8 a cut-away perspectlve vlew showing the ar-rangement of bottom flaps that form bottom 6 in the preferred embodlrnent of the present lnvent;ion. Short, slde flAps 2,7 overlie wlder bottom flap 8, whlch ln turn overlles wlde bottom flap 6. Preferably, flap 6 and flap 8 are bonded to one an-other by glue, hot melt adhesive, pressure-sensitive adhesive, ultasonlc weldlng in the case of plastic or metal, or any other known bondlng or fa3tenlng method. Flap 4 and flap 7 may be slmilarly adhered to flap 8 or flap 13 although thls ls not necessary and may be omitted. The flaps may be of any deslred cross-sectlonal shape or conflguratlon, and may advantageously be varled in the case of a contalner havlng slde walls in a hexagonal, octagonal, or the like conflguration. The wall thicknesses have been exaggerated for clarlty.
