Abstract

The method involves interconnecting cover films (41) or cover film segments bounding the receiving area (12) and forming edge region (11). An aperture is introduced in the edge region. The cover films or cover film segments are provided with a channel system (56) having one channel (45). The channel system crosses the portion of cover film or cover film segment covering the receiving area. Each channel at one end is provided with a branch (44) passed into two channel branches (42,43). A slit is arranged between two channel branches, interrupting the peripheral edge of bag packaging. An independent claim is included for high density sealing bag packaging.

Description

The invention relates to a method for producing a high-density pouch packaging and a high-density pouch packaging having at least one opening and with a receiving area surrounded by a plate-shaped edge region for inert packaging of an active ingredient-containing product, wherein the pouch packaging comprises cover areas or covering foil sections delimiting the receiving area and forming the edge area.

From the DE 10 2009 008 027 A1 Such a bag packaging is known. The single closed pouch packaging is torn from the stack along a perforation. Thereafter, the bag package is opened by pulling the base and cover sheets apart at two tabs.

The present invention is based on the problem to develop a stackable high density bag packaging that is easy to open and fast. In addition, the original presence and configuration of all individual bag packages should be recognizable in the stack.

This problem is solved with the features of the main claim. For this purpose, the cover films or cover film sections each have a channel system with at least one channel. The gutter system traverses the portion of the cover foil or covering foil section which covers the receiving region. Each channel has at one end a branch into two gutter branches. In addition, a circumferential edge of the bag packaging interrupting incision is disposed between two gutter branches.

In the production of the high-density pouch packaging, the gutter system is introduced by means of a laser in the cover foils or covering foil sections.

The FIGS. 1 to 3 show a bag package (10) for a drug-containing product (5). Such pouches (10) are presented in stacks, each individual pouch (10) containing a dose of the active ingredient (5). If, for example, one dose per day of the active substance-containing product (5) must be taken, a stack contains, for example, seven pouches (10) for one week's bathing requirement.

The individual bag packages (10) of a stack are identical to one another, for example. In the plan view of FIG. 1 the bag package (10) has a rectangular base. The length is eg 15% larger than the width. Also oval, round, polygonal, etc. bases are conceivable.

The bag package (10) consists in the embodiment of two cover films (41, 61) which are glued or welded together in a peripheral edge region (11). The individual cover film (41; 61) is constructed, for example, as a multilayer laminate and has an inner metal layer, e.g. an aluminum layer having a thickness greater than 9 microns, e.g. the thickness is between 12 and 25 microns. The bag package (10) is thus highly sealed. The cover sheets (41, 61) may be made of different materials and have different strength values. The one of these here as cover films (41, 61) designated films may be formed as a base film (41, 61). Also, e.g. one cover sheet (41, 61) transparent and the other non-transparent. The bag package (10) may also be made from a single folded cover sheet (41; 61) whose two cover sheet sections are then joined together.

The edge region (11) is formed, for example, plate-shaped. Its minimum width in the embodiment is 10% of the width of the bag package (10). It surrounds a receiving area (12). The on the drawing level of the FIG. 1 projected area of the receiving area (12) is 46% of the projected footprint of the bag package (10). The projected area of the receiving area (12) is thus between 40% and 60% of the projected footprint of the bag package (10).

In the presentation of the FIGS. 1 and 3 is in the airtight and moisture-tight closed receiving area (12) the active ingredient Product (5) arranged inert. The on the drawing level of the FIG. 1 projected area of the active substance-containing product (5) is smaller than the projected to this plane surface of the receiving area (12). The receiving region (12) thus comprises a strip (13) which surrounds the active substance-containing product (5).

The receiving area (12) has in the representation of FIG. 1 at least approximately the shape of a rectangle with rounded corners. The lower roundings (14, 15) in this illustration, for example, have the same radius. The right upper rounding (16) is oriented in the direction of the receiving area (12). The left upper rounding (17) has, for example, a radius which corresponds to one quarter of the width of the bag package (10). The boundary (18) connecting this rounding (17) to the left lower rounding (14), for example, makes an angle of 5 degrees with the outer edge (26) of the pouch packaging. This angle may for example be between two degrees and 30 degrees, wherein the width of the edge region in the representation of FIG. 1 increases from bottom to top.

In the edge region (11) are - the receiving area (12) facing away from and spaced therefrom - two openings (19). The bag package (10), for example, by means of rivets, which penetrate these openings (19), inextricably mounted in the stack.

On one of the long sides (21) carries in the representation of FIG. 1 the bag package (10) outside the receiving area (12) has a mark (22). For example, the can number, a production number or another identification number may be engraved here, for example.

The edge region (11) has in the embodiment of FIG. 1 a few millimeters below the upper end of the receiving area (12) an incision (23). The length of the incision (23) is for example 60% of the edge width in this area. In this illustration, two channel branches (42, 43, 62, 63) are arranged symmetrically to the incision (23) in each of the cover films (41, 61) or covering film sections. These are channel-shaped, uninterrupted recesses of the cover films (41, 61) or covering film sections. They have a constant, for example, U-shaped cross-section in the embodiment. For the incision-side longitudinal edge (24) of the pouch packaging (10), all gutter branches (42, 43, 62, 63) have, for example, a distance of one millimeter.

The two channel branches (42, 43, 62, 63) of a cover film (41, 61) or of a cover film section unite in a branch (44, 64), which in the exemplary embodiment is arranged at the transition of the rounding (16) to the receiving region (12) , Both channel branches (42, 43, 62, 63) pass tangentially into a channel (45, 65). The respective groove (45; 65) has, for example, the same cross-section as the gutter branches (42, 43; 62, 63). In the presentation of the FIG. 3 the single channel (45, 65) has a U-shaped channel bottom (46, 66) and walls (47, 67) opening from the inside to the outside. In this embodiment, the gutter system (56) of the cover sheet (41) and the gutter system (76) of the cover sheet (61) each comprise a groove (45; 65).

In the exemplary embodiment, the individual channel (45; 65) extends in the direction of the active substance-containing product (5) offset parallel to the edge (25) of the receiving region (12). For this example, it has a distance of one millimeter. It thus crosses the part of the cover film (41, 61) covering the receiving region (12) or the cover film section. In the in the Figures 1 - 3 The pouches (45, 65) are arranged, for example, in the outer surfaces (48, 68) of the cover foils (41, 61) in the region in which the inner surfaces (49, 69) are shown. Cover the strip (13).

The channel (45, 65) runs along the edge (25) of the receiving area (12) to the lower rounding (14). It thus covers a segment of the recording area (12) of 90 degrees. The segment traversed by the channel (45; 65) may have an opening angle between 75 degrees and 90 degrees. The chord of the channel (45; 65) in the receiving area (12) is longer than the largest dimension of the active substance-containing product (5). The radius of the bent portion of the channel (45; 65) is for example 20 millimeters. This radius is eg greater than 10 millimeters. The arc of the channel (45; 65) covers, for example, a sector of, for example, 85 degrees. The sector angle can be between 85-90 degrees. From the lower rounding (14), the channel (45; 65) runs in the illustration of FIG. 1 a right arc to the left outer edge (26), which it touches in the end point (51). However, the individual groove (45; 65) can also end in the edge region (11) between the receiving region (12) and the longitudinal edge (26).

If the groove (45) on a in the plane of the FIG. 1 If the transverse direction (27) is the abscissa and the longitudinal direction (28) the ordinate, the curve in the region between the end point (51) and the branch (44) gives a monotone, continuously differentiable curve. Each value in the transverse direction (27) is associated with exactly one value in the longitudinal direction (28) of the pouch packaging (10).

In the exemplary embodiment, the grooves (45, 65) of both cover films (41, 61) or both cover film sections are congruent to one another. The depth of the individual channel (45, 65) corresponds to a maximum of 90% of the thickness of the cover film (41, 61) or the cover film section. Instead of the described cross-section, the single channel (45, 65) may also have a rectangular, V-shaped, etc. cross-section.

In the production of the bag packages (10), for example, the grooves (45, 65) are introduced into the cover sheets (41, 61). This is done e.g. by means of a so-called laser scoring. In this case, individual areas of the surface of the cover film (41, 61) are removed by means of a laser. Due to the relative movement of the cover film (41, 61) and the laser to each other, the removal takes place along a line. In this case, the metal layer of the cover film (41, 61) are weakened, but this metal layer remains closed. For example, the channel system (56, 76) is introduced to a depth of 90% of the metal layer. The groove (45; 65) does not penetrate the metal layer, nor is the metal layer perforated. This ensures the tightness of the individual pouch packaging (10). After the first channel (45; 65) including a gutter branch (42; 43; 62; 63) is made, for example, the second channel branch (43; 42; 63; 62) is introduced from the branch (44; 64). In parallel with this, e.g. generates the mark (22).

The introduction of the gutter system (56, 76) can take place before or after the production of the pouch packaging (10) and the introduction of the active substance-containing product (5).

If the channel system (56, 76) is introduced into the individual cover films (41, 61), for example, before welding, the cover films (41, 61) including the active ingredient-containing

Products (5) superimposed and flavored with each other. This connection takes place, for example, over the entire area in the edge region (11) of the pouch packaging (10).

The finished pouch packaging (10) is stacked and riveted. It can now be handed to the user in the stack, e.g. in a so-called calendar pack, be presented. Each single dose is high density and inert packed. The single dose is thus gas-, aroma- and moisture-proof protected against the environment.

For removal, the user holds the stack with his left hand, for example, and grabs the pouch packaging (10) with two fingers of his right hand, for example. Here, for example, the thumb lies on the receiving area (12) and the index finger supports the back of the receiving area (12). If the right hand is now moved to the left, the bag package (10) tears at the incision (23). The crack continues - with increasing resistance - on both cover sheets (41, 61), for example up to the branches (44, 64). If the crack from the incision (23) not obliquely, but obliquely continues, he encounters the upper gutter branches (42, 62) or the lower gutter branches (43, 63). There, the crack is diverted into the gutter branches (42, 43, 62, 63). Along the gutter branches (42, 43, 62, 63), which have a smaller material thickness than the surrounding cover foil (41, 61), the tear continues in the two cover foils (41, 61) in the direction of the branches (44, 64) , At least from the branches (44, 64), the crack follows the troughs on further tearing (45, 65). Moving the right hand further to the left, cf. FIG. 1 , there is an increasing crack growth to the left. Due to the described geometry of the channel (45, 65), the opening of the bag package (10) can be done in a single train. Since the course of the channel (45; 65) has a component in the transverse direction (27) greater than zero along the entire channel length in every increment, The tearing is not hindered or blocked. The user does not need to change his train direction. The receiving area (12) is opened outside the active substance-containing product (5). At the same time, a bag-shaped part (29) is torn off with the active substance-containing product (5), cf. FIG. 4 , The active substance-containing product (5) in this case remains in the bag-shaped part (29) of the bag package (10), which the user holds with the opening (31) up in the hand. Due to the large opening (31) of the bag (29), the active substance-containing product (5) can now be removed without difficulty.

The opening procedure described here is suitable for right-handed people who pull with their right hand. However, the same pouch packaging (10) can also be used for left-handers. For this purpose, the back (32) is directed upward, see. FIG. 2 , The opening process is now analogous, as described above. Even with this pouch packaging (10), a single hand movement is enough to open.

After tearing off the bag (29) with the active substance-containing product (5), the upper and left edge region (33), for example, of the bag packaging (10) remains in the stack. The mark (22) is in this part (33) of the edge region (11). Thus, the user or a third person can easily check whether, for example, the intended for the day dose of active ingredient-containing product (5) is already taken. In addition, even after the removal of a bag packaging (10) the original position and the configuration of all individual bag packages (10) can be recognized without any problem. Even if all bag packages (10) of the stack have already been removed, proof of the original arrangement of the individual cans in the calendar packaging is thus possible.

The gutters (45, 65) and trough branches (42, 43, 62, 63) may also be formed by other than the described method, e.g. Etching, engraving, etc. are introduced into the cover sheets (45, 65) or in the cover film sections.

The grooves (45, 65) of both cover films (42, 43, 62, 63) or cover film sections can also be arranged offset from each other in regions. For example, then results in an oblique crack along the bag packaging (10). The resulting tear edge (34) can be arranged, for example, so that the cover film (41, 61) facing the user is cut deeper than the cover film (61, 41) facing away from the user.

The grooves (45, 65) and / or the gutter branches (42, 43, 62, 63) can also be arranged on the inner surfaces (49, 69) of the cover foils (41, 61) or the cover foil sections. It is also conceivable to insert the grooves (45, 65) of a cover film (41, 61) in the inner surface (49) and the groove (65, 45) of the other cover film (61, 41) into the outer surface (48, 68) , Also, one or both ring branches (42, 43, 62, 63) may be incorporated in another surface (48, 49) than the groove (45, 65).

In the exemplary embodiment, the channel (45, 65) is linear. However, the channel (45, 65) may also have a corrugated shape, it may have side channels, etc. The bag package (10) may also include channel systems (56, 76) with a plurality of channels (45, 52, 65), cf. FIG. 5 , In this FIG. 5 For example, a bag package (10) is shown, which is torn open from left to right. The single channel (45, 65) terminates in the cover sheet (41, 61). A subsequent channel (52) then has two Rinennzweige (53, 54), which lie on both sides of the channel end (55) of the first channel (45). When one-handed rupture arise - starting from the incision (23) - so short zones of increased resistance. This can be difficult, for example, accidental tearing of the bag packaging (10).

Of course, it is also conceivable to combine the various embodiments mentioned with each other.
