Composite package, package laminate and package sleeve blank for a composite package

Abstract

A composite package, in particular a beverage carton package for liquid foodstuffs is depicted and described which consists at least partially of a package laminate, having a package base body including package edges, an at least partially angular package base and package gable wherein the package base body defines, in an idealised manner, a package front side, package rear side and at least two lateral package sides attaching to the package rear side as well as a package laminate and a package sleeve blank for manufacturing such a composite package. In order to improve grip and ergonomy for an easy to manufacture package, provision is made for the package front side to have a positive arching at least in sections which in each case passes into a lateral package side for a grip panel to be formed at least in sections in the region of the package rear side.

DESCRIPTION OF THE INVENTION

(11) The embodiment of a composite package P according to the invention depicted in FIG. 1 is formed by a package base body 1, a package base 2 sealing said package base body and a package gable 3 forming the head part of the package. All three parts are shaped by deforming fold processes from one and the same package material. Thus the package base 2 is shaped on a folding mandrel of a package machine via package fold lines 8 and sealed by means of ultrasound (alternatively hot air, adhesive, etc. are for example conceivable). The base-sealed semi-finished package product is then filled via the open head region with a desired filling material and a package gable 3 chamfered forwards towards the package base body 1 is then formed via further package fold lines 8 which seals the package by means of an ultrasonically welded transverse sealing seam 12. The excess package material sections resulting from the shaping of the package gable 3 form package ears 13 which are turned over via foldings on the package base body 1 and are attached to its side wall. Different defined package edges 5 result by the folding and shaping processes on the composite package P. In the embodiment shown, a pouring element 15 is applied on the package gable 3 from which the product can be poured out.

(12) The pouring element is faded out from the depiction of FIG. 2 such that a local weakening 14 of the package material is visible. This serves for easy initial opening of the composite package P and is explained in greater detail further below. The composite package P has four package base corners 21, 22, 23, 24 and four package gable corners 31, 32, 33, 34. Further package fold lines 8 are formed on the package base body 1 which define further package edges 5 on the shaped composite package P.

(13) In order to now describe the composite package P geometrically, projections PJ1, PJ2, PJ3, PJ4 are defined by the corners of the package base 2 and the package gable 3. The package base body defines a package vertical axis PA. The package vertical axis PA and the projections PJ1, PJ2, PJ3, PJ4 are located in the exemplary embodiment shown substantially parallel to each other. Package front side PV, the package rear side PH and two lateral package sides PS can be defined in an idealised manner via surfaces spread out on the projections PJ1, PJ2, PJ3, PJ4. These surfaces are delimited by the packages edges 5 on the package base 2 and package gable 3. Thus, for example, the front side PV is defined by the package edge 5 between the two front package base corners 21, 22 and the curved gable front edge 6 between the two front package gable corners 31, 32. The package ears 13 are attached at the two lateral package sides PS. The package front side PV is positively arched with regard to and along the package vertical axis PA. This positive arching 10 extends almost over the entire height of the package and is continued laterally via the projections PJ1, PJ2 and passes into the lateral package sides PS such that an ergonomic grip and hold of the package is facilitated for the consumer.

(14) FIG. 3 shows the package rear side PH of the finished composite package P with a longitudinal sealing seam 18. The rear projections PJ3, PJ4 are only formed in the region of the package base corners 23, 24 and in the region of the package gable corners 33, 34 as package edges 5. Instead of the package edges 5, grip panels 11 are formed over a relatively wide region. This facilitates an ergonomic grip and hold of the package for the consumer.

(15) FIG. 4 shows the composite package P from below. The package base 2 is designed in the exemplary embodiment as a block base. The grip and hold region of the package formed in the centre of the package is cut along the surface I-I such that the contour of the package material is visible in the cut view of FIG. 5. It shows the two grip panels 11 on the package rear side PH and the positive arching 10 on the package front side PV.

(16) In FIG. 6, the cut structure of the package material is depicted with a carton support layer 16 which is laminated on both sides with a polymer layer 17. The weakening 14 is designed in the exemplary embodiment shown and in this respect preferred as a prelaminated hole. In this case, a hole is punched out of the carton support layer 16 prior to the laminating process such that the local weakening 14 is formed only by the polymer layers 17 in the finished package material.

(17) FIG. 7 shows an interval of the package material provided with creases 7 as a ready-to-use package laminate L for forming a composite package P. The creases 7 predefine the subsequent fold lines 8 for the transport and package manufacture of which some form the subsequent package edges 5. The package laminate L is further printed with a decoration (not depicted) and is initially present as endless material (roll goods).

(18) The upper and lower side of a package sleeve blank M cut to the interval of a composite package P to be made and connected via the longitudinal seam 18 to a pipe can be viewed in FIG. 8a and FIG. 8b. Said package sleeve blank M is laid flat via lateral fold lines for space-saving dispatch (for example in a cardboard box). The package sleeve blank M is lastly supplied to a package machine (operating here in the sleeve process) which shapes, fills and seals the composite package P.
