Definitions

• the invention relates to a tube packaging which is particularly suitable for food in lumpy or portioned form and which contains the respective product in a welded-on plastic tube.
• Hose packaging is widely used for packaging food and luxury foods. This applies in particular to foodstuffs in lumpy or small-part form which are intended to be consumed in portions, whether as a staple food, an ingredient for the preparation of dishes or as a snack for direct consumption.
• Tubular packaging is easy to manufacture and fill, easy to store and handle, good protection for the food packaged in it, and allows food to be labeled either directly on the tubular film or with stickers. The hygienic requirements are fully taken into account.
• Hose packaging usually consists of a film tube, the two ends of which are sealed by gluing or welding. In this way, the goods are optimally protected against environmental influences. To remove the goods, the packaging must be torn open or cut open. If no scissors are at hand, all that remains is tearing open, which is usually done from one of the welded sides. In many cases, tear-open aids are available, for example in the form of an incorporated tear-open thread or a notch which serves as a starting point for the tear-open process. But even then the tearing process is often not controllable, so that the hose packaging is uncontrolled over more than the desired length tears open. It can be assumed that in many, if not the majority of cases, the tearing process does not lead to an opening which is of the desired size. The consequences can be uncomfortable, especially with liquid content.
• Tear-open guides in the form of a ruler integrated in the packaging have been proposed for plastic bags. However, this does not enable a controlled breakdown; rather the crack migrates.
• a relatively small opening is required here, which is aligned with the size of the package contents. Such an opening of a coordinated size is also desirable from a hygienic point of view. On the other hand, the opening must not be too small for handling reasons.
• the object of the invention is therefore to provide a tubular packaging which enables the production of an opening which is defined and to the piece size of the food packaged therein.
• the opening should be able to be made reliably by hand by tearing it open without external aids and should leave the packaging in tact so far that the remaining amount of products contained therein can be stored without further ado.
• a packaging of the type mentioned at the outset which has a tear-open aid in the region of a weld seam and is provided with a sticker, the side of which facing the weld seam is designed as a curved tear-off edge which is suitable for a tear which starts from the tear-open aid to catch and lead to the edge of the packaging.
• the hose packaging according to the invention is particularly suitable for foods which are intended for consumption on the go. These are, for example
• chocolate, muesli, vegetable or fruit bars which serve as a "small meal” for travel, as a snack in school or as an "energy supplier” Exams, meetings or generally as a snack at work are valued.
• conventional snacks such as nuts, peanuts, chips, flips, pastries, sweets and the like, are also suitable, which are intended to be consumed in small portions or quantities, the rest of which should be reliably retained in the already opened packaging.
• the tear-open aid is also suitable for packaging with liquids or consumables. It is by no means only suitable for the food sector.
• the packaging according to the invention is particularly suitable in combination for a packaging according to DE-GM 297 15 892, which is intended to be attached to or in an object by means of a fastening means.
• the hose packaging according to the invention is a specially designed, conventional packaging in which the two hose ends are sealed by means of a welded or glued seam.
• a sticker is now provided which has a curved tear-off edge on one of its sides facing the weld seam.
• the sticker consists of a sufficiently crack-resistant material, in particular plastic or paper. So that this tear-off edge can perform its intended function, there is a tear-open aid on the packaging in the area of the weld seam in an area directly adjacent to and running towards the tear-off edge, for example in the form of a notch or an incision. Naturally, this tear-open aid does not extend into the inside of the packaging, but ends in the sealed area.
• Many hose packages have teeth or corrugations in the area of their sealing seams, which can easily serve as a tear aid. In this case it is advisable to color-code a suitable starting point.
• the tear-open aid is located with the packaging held upright - with the weld seam at the upper end - above the curved tear-off edge of the
• the sticker is arranged at a relatively short distance from the weld seam, for example at a distance of 0.2 to 5 cm. The distance depends on the size of the packaging and the sticker and on the length of the tear-off edge and the size of the opening to be made in the packaging.
• the tear-off edge takes a curved course and is suitable for catching a tear originating from the tear-open aid and leading it to the edge of the packaging.
• the tear-off edge leads the tear perpendicular to the edge.
• the curved course ensures that the tear-off edge and crack course are always at a favorable acute angle to one another. Emigration of the crack from the intended course does not occur.
• the sticker can be guided around the edge of the packaging, it being expedient that it runs congruently on the back of it with the front.
• This variant is particularly useful for packaging with side folds.
• the tear-off edge expediently has an S-shaped and preferably a sinusoidal curve, the curve being in the upper region, ie. H. nestles against the edge of the sticker in the area adjacent to the weld seam and runs with the other end towards an adjacent side edge of the sticker.
• the amplitude of such a sinusoidal configuration of the tear-off edge suitably corresponds to 10 to 20% of the length of the curve.
• the curve runs in particular around an axis that intersects the edges of the sticker at an angle ⁇ of 120 to 150 °, in particular 135 °.
• An intersection angle of 135 ° with both sticker edges defines an isosceles triangle in relation to the triangle formed by the axis and the dropped legs of the sticker.
• the S-shaped curve which is located at the upper edge or that of The side of the sticker that faces the weld seam hugs and ends on the adjacent side at approximately a right angle to the edge.
• the tear-off edge is formed by an approximately quarter-circular cutout in the corner region of the sticker.
• the sticker may well be a conventional label that has the appropriate design on the edge facing the tear-open side. Alternatively, however, it can also be a correspondingly curved strip of paper or plastic, which has no other functions. When using transparent plastic film, the sticker on the packaging itself is hardly noticeable. Printing is also possible.
• the tear-open aid is, for example, a notch in the weld seam. This can also involve a large number of notches, such as can be found as a serrated edge in such tubular film packaging. In this case, it can be useful to mark a notch that is particularly favorable to the tear-off edge, for example by means of a color design. Welded-in usual tear threads are also suitable.
• the invention relates to a sticker or a label which can assume the function of a tear-open edge for the hose packaging described above and which corresponds to the above definitions.
• the invention also relates to tubular packagings of this type with goods therein, which may also be those which are not intended for the food sector, for example fertilizer tablets, detergent tablets or detergent tablets or tablets.
• Figure 1 is a hose packaging according to the invention with tear aid and sticker.
• Fig. 2 variants of strip-shaped stickers;
• FIG. 1 shows a preferred embodiment of a hose packaging according to the invention with a label arranged thereon.
• the tube packaging 1 itself consists of a film tube which is sealed at both ends by means of weld seams or adhesive seams 2.
• weld seam used here is also to be understood as meaning other types of seals, for example adhesive seams.
• the label 3 On the tube packaging is the label 3, which has an upper edge 5 in the area of the weld seam 2 and a side edge 6 adjoining it.
• the tear-off edge 4 which first bends inwards from the upper edge 5 and then converges towards the edge 6 of the label, on which it impinges essentially at right angles.
• the S-shaped tear-off edge 4 has a substantially sinusoidal course about the axis 8, which cuts the label edges 5 and 6 at an angle of 135 ° and thus defines an isosceles triangle with the omitted corner area of the label.
• notches 7 which are intended as a tear-open aid.
• the notches which are located in relation to the longitudinal direction of the hose packaging, above the tear-off edge 4, lead to a tear when torn, which strikes the tear-off edge 4 as it passes through the foils and from there towards the point D on the lateral edge 9 of the Packing 1 is performed.
• the opening achieved according to the invention with the hose packaging according to the invention thus runs from the tear-open point 7 above the tear-off edge 4 to this and further to the end point D on the package 1 and from there on the back to the tear-off point 7, and thus results in a well-defined opening of a predetermined extent .
• FIG. 2 shows various stickers 3 in the form of strips, the edge 4 of which faces the tear-open side of the packaging and guides the tear ensuring curvature.
• the variants a, c and e have an elongated S-shaped course, the variants b and d have a simple curvature pointing towards the tear-open side.
• Variants c to e are intended to be applied around the packaging side edge on the front and back.
• Variant e is intended for side-folded packaging.
• the number 6 designates the side edge of the sticker, the numbers 10 and 11 folds to adapt to the edge and corresponding folds on packaging bags.
• FIG. 3 shows a side-folded bag 1 equipped according to the invention with upper and lower seals 2 and a tear-open aid 7.
• the sticker 3 is provided with a tear-off edge 4 pointing towards the top edge of the bag and is guided around the side edge 9 of the bag with an additional fold 12.
• the Appiikat 3 is congruently arranged on the two sides of the bag.
• the sticker according to the invention with the curved tear-off edge can be applied to a tubular film packaging both on one side and on both sides. It can be applied so that essentially the entire side of the package is opened, or only a section.
• a sealing strip equipped with self-adhesive strips which for example can also be equipped with a grip tab, is readily possible. Such a closure can then be glued around the open end of the packaging on the back.
