Definitions
- the invention lies in the field of packaging technology and relates to a method for the production of sample bags according to the generic term of the first, independent claim and a device for performing the Process and sample bags produced by the process.
- the manufactured Sample bags contain fluid or solid samples and are special suitable for automated further processing with high processing speed, for example for attachment to or insertion in printed products.
- the additional steps for shape stabilization are such in the manufacturing process the bag integrates that hardly any additional work arises. As a rule, the shape stabilization at the No loss of speed will be accepted. On the tool side there is possibly one, measured on the achieved Advantages, but little additional effort required.
- sample bags produced by the process according to the invention are isolated or on the strand much easier to handle than known sample bags, since it is a stabilized one, that means only when handling still have an insignificantly changing shape. Man For this reason, it can be easily made into rods using known means line up, grip individually and process further, especially with high ones Processing speeds.
- Figure 1 shows in a very schematic manner a system for packaging sample products in bags, as used in the prior art.
- the principle of how the packaging process essentially works is known: From rolls 1, film webs 1 'with, for example, a heat-fusible coating via deflection rollers 3 into a system part 10 for receiving the sample product become arrow direction z (small z indicates the process direction of the product) 2 pulled.
- the film webs are closed into bags by forming continuous longitudinal seams and equidistant transverse seams 6, the resulting bags being filled with a solid object 2, for example, between the creation of successive transverse seams 6.
- the finished sample bags 12 are typically pillow-shaped.
- FIG. 2 and 2a show an exemplary variant of the method according to the invention and the corresponding product.
- the sample bags are reshaped after they have been closed, if they still form a quasi-endless bag strand, by rolling or folding and pressing the longitudinal edges of this bag strand.
- FIG. 6 again shows a very schematically illustrated plant part, which has a pair of rollers 30 for producing the longitudinal seams 6 ′ and the transverse seams 6.
- the longitudinal seams 6 ' are not placed extremely on the film edges but spaced from them or have a correspondingly increased width.
- the longitudinal edges are rolled or folded in there by corresponding guide elements (not shown) and then pressed in such a position, for example by a further pair of rollers 31, possibly welded and thereby stabilized in this position.
- the rolled-up or folded-in longitudinal edges 32 of the bag strand can also be stabilized in another way, for example by appropriately introducing an adhesive before rolling in and by pressing after rolling in.
- FIG. 2a shows a sample bag produced in the system according to FIG. 2 in a section parallel to the transverse seams 6.
- the FIGURE shows further, identical sample bags with dash-dotted lines as they are arranged in a stack.
- the longitudinal edge regions 32 of the sample bag which have arisen as a result of the rolling in or folding in and are stabilized by the pressing, welding and / or gluing act as support webs by means of which the shape effect of the still essentially pillow-shaped bag middle region is canceled.
- the edge regions 32 also have a shape-stabilizing effect due to their increased rigidity.
- FIGS. 3 and 3a to 3c show a further, exemplary variant of the method according to the invention, which variant in turn has an additional, shaping method step compared to the manufacturing method according to the prior art.
- a roof ridge-shaped fold 70 that is to say three fold lines each with an alternating folding direction, is produced on one (1 ") of the film webs (FIG. 3a) prior to the production of the longitudinal seams 6 'parallel to the longitudinal edges of the film web with a corresponding folding tool (not shown)
- the film web 1 "with the folds 70 is then continued in such a way that the folds are given the desired height by correspondingly reducing the film width (FIG. 3b).
- the film web 1 "is brought together with the other film web 1 'and 70 double seams (represented by two dash-dotted lines) are created as longitudinal seams on both sides of the folds.
- the bags are then filled and the transverse seams 6 are created.
- a cut is made parallel to the cross seams through a finished sample bag shown in Figure 3c. It is obvious that through the double longitudinal seams 6 'fixed folds 70 perform the same function as that by rolling or folding in thickened edge areas of the bags according to FIG. 2a.
- a possibly significant difference to the embodiment according to Figure 2a is that the folds 70 after the manipulation they as a form-stabilizing agent facilitate or only make it easy again can be compressed and then only in a very small amount Mass thicken.
- that means according to sample bags Figure 3c can easily and safely even at high processing speeds for example, introduced into printed products.
- the folds 70 can simply be fixed in or on the printed product or later be flattened by pressing, creating the pouch in the printed product certainly only applies a minimum.
- Variants of the method according to FIGS. 3 and 3a to 3c can consist in that one or two folds are created on each film web and in that the folds are not ridge-shaped (a triangular cross-section have) but, for example, a segment of a circle or have a trapezoidal cross section.
- the initial width of the two Foil sheets can be the same size or matched to one another in such a way that the longitudinal edges of the two sheets lie on top of one another in the finished bag.
- FIGS. 4 and 4a show a further, exemplary variant of the method according to the invention and the product produced with it.
- the bags produced according to this process variant are stabilized by an additional shaped element.
- the shaped elements are frames 33, which are introduced as quasi-endless frame webs 33 'between the film webs 1' and 1 ", are connected to the film webs when the longitudinal and transverse seams are created and are separated from one another together with the bags.
- the frames 33 consist for example of plastic (solid or foamed) and are for example 0.5 to 1mm thick.
- FIG. 4a shows a sample bag with a frame 33 on average parallel to the transverse seams. The figure also shows that peelable film area 34 in closed and in open (34 ') position.
- FIG. 5 illustrates a further, exemplary process variant of the process according to the invention and the product produced with it.
- the starting products are in turn two film webs 1 'and a frame web 33', the frame web not being fed between the film webs but next to them, as in the method according to FIG. 4.
- the frames 33 can have gaps at a corner, for example 35 have.
- the film webs 1 'of the sample bags are, for example Provide tearing notches at the appropriate points during the cutting process. Instead of the gaps 35 shown and the corresponding tear notches can for an easy opening of the sample bag according to Figure 5 analog 4, the film web facing away from the frame web 33 ' 1 'can be chosen somewhat wider and one with the other film web Incoming peelable connection, making opening analogous to opening of the sample bag according to FIG. 4a.
- FIG. 6 illustrates a further, exemplary variant of the method according to the invention and the product produced with it.
- two strips 40 are introduced into the process as additional shaped elements, which strips are connected, for example welded or glued, to one of the film webs 1 'or to the bag strand in the region of the longitudinal seams.
- Direct extrusion of a suitable plastic onto one of the film webs 1 'or onto the bag strand for the production of the strips 40 is also conceivable.
- the strips 40 can also be introduced analogously to the method described in connection with FIGS. 4 and 4a before the seams are made between the two film webs 1 '.
- the strips 40 can in terms of material and material structure and in terms of Cross section within wide limits on the film webs used, on the Contents of the bags and / or to be adjusted to manufacturing parameters. It are strips of cardboard, paper or plastic (solid or foamed) with any hollow or compact cross sections imaginable.
