Description

The This invention relates to a blank for forming a packaging means with a window element, in particular for free-flowing Goods such as detergents and / or cleaners.

State of the art

For the packaging of a variety of liquid, gelatinous, solid and / or free-flowing products such as from the group of laundry detergents, dishwashing detergents, Pharmaceuticals, Personal care products, Agricultural aids, Building materials, Dyes, Adhesives or food, it is common today to carton packaging to use.

Out The prior art is a variety of cardboard for the purpose the storage and transport of free-flowing goods known, including those in a wall of cardboard packaging Viewing windows have been let in, leaving the contents of the cardboard box is visible from the outside.

These Viewing windows are made by corresponding punched in the folding blanks formed, with the viewing openings thus formed then with a transparent plastic film covering the viewing opening spans the cardboard wall and back with the cardboard is glued surface.

By the punching and material removal in the folding blanks is however, the stability of such with a viewing window provided folded folding blank, so that the size Such window for stability reasons is regularly limited.

It is therefore regularly desirable, a the largest possible effective visible area with the least possible stability impairment to achieve the packaging means formed from the blank.

Further the walls of such packaging are regular printed with product descriptions, and / or advertising messages, the View window occupy as little as possible of this pressure surface should.

Usually The blanks are connected in such a way that one Upper and lower open fuselage arises. Because these blanks space as possible need to be transported to bottling, it makes sense not to put the hull in an upright position, but rather folded flat to transport.

today It is widely used, partially glued, flat-lying foldable Boxes with less prefabrication the packing operation to deliver as a flat blank, with the forming of the box to the hollow body on a packaging machine. To the Filling such a carton is set up again and glued on the bottom side. After the filling process can also the lid are glued.

The Hull-bonded folding blanks are used for transport along Weakening or folding lines folded flat and stacked flush on top of each other. Often is a predetermined number of flat-folded and one above the other stacked folding blanks with one or more bands against each other fixed and lashed.

Object of the invention

task The invention therefore provides a blank for forming a packaging means to create the type described above, which from the state overcomes the technology known disadvantages and the largest possible effective visible area with the least possible reduction the stability of the packaging material formed from the blank provides.

A Another object of the invention is to design the blank in such a way that the viewing window element during transport in lying flat, folded condition of the blank not damaged becomes.

These Tasks are inventively by a folding blank according to the generic term and with the characterizing ones Characteristics of claim 1 solved.

Advantages of the invention

The Invention allowed by the hull inside bulging of the window element an increase in the effective viewing area of the window element, as compared to a planar window element a larger surface and thus one larger effective visible area at the same Punching is provided from the blank. Thus, at same punching and thus the same stability properties of the packaging means formed by the blank by the hull inside Bulge of the window element an enlargement of the effective visual surface causes.

As a result, the still comparatively simple viewing window in cardboard boxes can also be made more appealing and conspicuous, for example as a concave lens, a three-dimensional figurative or floral element. This makes it possible to provide a greater variety of aesthetic attractions with regard to the packaged products, what with can be critical to the commercial success of a product. In particular, by using a projecting in a cubic cardboard concave, lens-like Sichtfensterausformung can be awakened in a detergent contract at the customer an association with a washing machine, which also has a similarly designed glass door.

Further can the rigidity of a cardboard wall against buckling and Bending through the use of an inventive Window element can be increased, as by the inside arched window element an enlargement the area moment of inertia of the corresponding Carton wall is effected.

window element

The Window element can bulge any hull inside Have shape. Rumpfinnenseitig bulges means that the window element from the plane of the wall in which it is located, out and inside protrudes into the hull of the formed packaging means.

The Window element is preferably made of a dimensionally stable, thermoformable, molded plastic.

In Another embodiment of the invention is the window element multi-layered. The window element may in particular consist of a carrier film, which partially from an opaque or in whole or in part of a transparent or semi-transparent Material is coated. This material may be preferably a color change film act. In particular, the material can be die-cut to a section overlap to achieve the retardation film.

The Window element can on the blank in particular by a cohesive Be fixed connection.

spacer

By the stacking of Faltzuschnitte can on the such designed window elements such a large stacking pressure arise that these are damaged by the stack pressure become. The damage can not only be optical, z. B. in the form of dents, dents or scratches, but includes also structural damage such as cracks, fractures or holes through the later in the cardboard box stored product may inadvertently enter the environment. The risk of damage from the inventively molded Viewing windows increase even more through the use of lashing straps for mutual fixation of stacked folding blanks as well as by the occurrence of additional transverse and shear forces during transportation.

Around Damage to the window element during transport of the window flattened folding blank with already glued hull can be avoided be advantageous in the first, flat position of the Blank at least one spacer, the stacking compressive strength greater than the stacking strength of the window element, with a height at least equal to the depth of the window element in such hull inside to arrange and configure that a Damage to the window element by stacking the flat lying Blanks is substantially prevented.

The Spacer may be an integral part of the blank. So For example, it is conceivable that the spacer element as a formed on the blank tab is formed on the inside of the fuselage is foldable. The tab can reach the necessary height also be folded several times.

In Another embodiment of the invention is the spacer element from the punched out, the cut to the use of the window element is formed, shaped. The punching can do this completely be removed from the blank or over a material bridge remain connected to the blank, the punching then just around the material bridge is pivoted around on the inside of the hull of the blank. This has the advantage that the punching is not considered waste in the production process incurred, but as a functional element in the blank formed packaging is used.

Further The spacer may also be a separate part from the blank be educated. The spacer element can therefore also be made of a plastic, a blank of cardboard or cardboard, wood, or metal be prepared.

Prefers is the spacer element by a positive connection, such as gluing, on the inside of the hull of the blank fixed.

Around the action of stacking forces on the window element is to prevent at the lowest possible cost of materials, is It is advantageous that the spacer element in the immediate vicinity positioned to the window member receiving punch is, so that a bend of the wall, which is the window element absorbs as little or as completely prevented is.
