ABSTRACT:
SPECIFICATION
The invention relates to a hinge-lid packet made of (thin) cardboard, comprising a packet portion and a lid which is connected by a hinge in the region of a lid rear wall via a line joint to a packet rear wall, a collar being arranged in the packet portion and attached with lower fastening surfaces in the region of the collar front wall and collar side flaps to the inner side of a packet front wall or packet side walls and of which the region protruding from the packet portion forms free visible surfaces. In addition, the invention relates to a method and device for manufacturing hinge-lid packets of this type.
The standard design of hinge-lid packets is such that a collar is arranged in the packet portion, a partial region of which collar protrudes from the packet portion. This upper portion of the collar is enclosed by the lid when the packet is closed. The collar consists of a separate blank, likewise made of (thin) cardboard, but can also be connected as one piece to the (main) blank for packet portion and lid. The entire hinge-lid packet consists in this case of one single blank.
On the previously usual hinge-lid packets, the collar is always configured continuously in white or in natural colours—corresponding to the colour of the material used for the collar. The hinge-lid packet itself, on the other hand, is covered externally on all sides in the region of the packet portion and the lid with coloured printing.
The object underlying the invention is further to develop and improve hinge-lid packets in respect of their design.
In achieving this object, the hinge-lid packet according to the invention is characterised by the following features:
a) the free visible surfaces of the collar front wall and/or collar side flaps protruding from the packet portion are covered with printing, namely with a printed colour layer applied to the visible surfaces,
b) the printing in the region of the collar front wall and/or collar side flaps is covered by a protective layer, especially a coat of lacquer or varnish,
c) the protective layer, or coat of lacquer or varnish extends over the whole region of the visible surfaces of the collar front wall and/or the collar side flaps and ends in the region of an upper front closing edge formed by the packet front wall, or in the region of upper side closing edges formed by the packet side walls, in such a way that the fastening surfaces of the collar front wall and/or collar side flaps are free of any protective layer or coat of lacquer or varnish.
Due to the invention it is possible to print the collar in a way that is perfect in respect of packaging technology. Preferably, only the regions of the collar protruding from the packet portion are provided with printing of this kind as the remaining regions are covered. In this preferred embodiment, an outer protective layer of lacquer or varnish such as is usual with this kind of printing is likewise only provided in the region of the surfaces of the collar protruding from the packet portion. According to the further ideas of the invention, this makes possible adequate or technically perfect fastening of the collar inside the packet portion by gluing. The surfaces to be provided with glue, namely the fastening surfaces of the collar, are thus, according to the invention, free of any printing and also free of any protective layers.
The invention can also be used especially advantageously with one-piece (total) blanks for hinge-lid packets. On this type of packet, the collar is expediently connected via flaps or webs folded in a Z-shape to the packet portion, especially the packet front wall.
On traditional hinge-lid packets with a collar made from a separate blank, the different surfaces of the collar, namely the printed visible surfaces and/or those provided with a protective layer on the one hand and the fastening surfaces without any printing and/or protective layer, are expediently applied in the region of a continuous web of material for the production of blanks for collars. The cuts or perforations for separating the collar and corresponding to the shape of the collar are then—controlled by print marks—realised in the region between successive visible surfaces and fastening surfaces of adjacent collars.
A further special characteristic is a device configured according to the invention for producing individual planks for collars. Here a pre-printed material web consisting of in particular thin cardboard is led through a cutting device with at least one cutting cylinder, on the circumference of which a number of (cutting) blades is arranged corresponding to the contour of the collars. The distance of the blades from one another is slightly larger than the corresponding dimensions of a collar in order to compensate for movement differences between the material web and cutting cylinder or cutter wheel.
Further details of the invention are explained in greater detail below with the aid of embodiments, given by way of example. The diagrams show:
