Description

The present invention relates to a bag at least one reclosable opening for Inside of the bag.

Such known bags often consist of Plastic and have a top reclosable opening such that a across the entire width of the opening of the bag extending bead made of plastic is provided, the in a corresponding, on the other side of the Groove pressed into the opening of the bag can be, creating a tight connection results; the bag is thus complete resealable.

Such conventional bags have the disadvantage that it is not visible on the bag itself, when part of the content is removed. Hereby the possible uses of such are conditional Bags limited, that is, they are suitable especially not for sale in the filled Condition with, for example, pourable goods; it only the sale remains for personal use unfilled condition, such as a pouch for freezing of food.

Based on the disadvantages discussed above and shortcomings of conventional bags is the object of the present invention based on a bag of the type mentioned above to further develop that he also as a packaged product from selling goods, that means also in the filled Condition can be used.

• mindestens eine längs einer vorzugsweise in sich geschlossenen Stanzlinie vorgestanzte, außenliegende, vorzugsweise streifenförmig ausgebildete Abreißlasche und
• mindestens einen unter der Abreißlasche angeordneten Kunststoffstreifen, der von innen außerhalb des Bereichs der Abreißlasche um die Stanzlinie herum mit der Innenseite des Beutels verbunden ist und der mit einem an sich bekannten Wiederverschluß versehen ist, aufweist,
  wobei der Beutel als Blockbodenbeutel bzw. Klotzbodenbeutel oder Kreuzbodenbeutel ausgebildet ist.

This object is achieved in a bag of the type mentioned in the teaching of the present invention in that the bag

• at least one outside, preferably strip-shaped tear-off tab pre-punched along a preferably self-contained punching line and
• at least one plastic strip arranged under the tear-off tab, which is connected from the inside outside the area of the tear-off tab around the punching line to the inside of the bag and which is provided with a reclosure which is known per se,
  wherein the bag is designed as a block bottom bag or block bottom bag or cross bottom bag.

With the bag designed according to the invention So the advantages of a known filled Bags as a sales package due to the advantages of those Pouch combined with reclosure. The End users have to open the bag Tear off the tear-off tab or tear it off completely; behind it is the one provided according to the invention Plastic strips with the resealable Opening whose width is roughly the length of the Tear-off tab corresponds, arranged; through this Then the end user can open the product Remove in portions and after removal using close the reclosure.

Furthermore, the for sale, for example in a retail store offered bags filled with the product recognizable whether this product packaging has ever been was open.

Now there is a bag with one reclosable opening to the inside of the bag known, the one along a self-contained Punching line pre-punched, external, preferably strip-shaped tear-off tab and one arranged under the tear tab Plastic strip that is inside the outside of the Area of the tear-off tab around the punch line is connected to the inside of the bag and the with a known resealable is provided.

However, this known bag (cf. US 5 601 368) filling as a problem in that the bag at both its head end and on at the foot of each with a sealed seam is sealed so that the well-known bag especially for large volume content that is not on once, but can be removed over time (corresponding to the possibility of Reclosing), more or less unsuitable is.

The well-known bag also has due to its Sealed seam in the bottom area no possibility of Parking or putting up, that is, the sensible Storage on what is just at reclosable bags of increased Meaning, which is about the (still) part of the bag content that is not required (tip) safely to keep.

For this reason, the feature of the present Invention that the bag as a block bottom bag or Block bottom bags or cross bottom bags is of particular importance to the invention, because this allows the (not) needed part the pourable goods are stable in the bag remain, with no risk that the Pouch tips over.

In other words, the present combines Invention the advantages of a known Blockbodenbeutels or Klotzbodenbeutels or Kreuzbodenbeutels with the advantages of resealable to surprising, for the Expert in unpredictable ways, the Functionality is particularly convincing if the Bags expediently to form the reclosable opening on one part at least one bead and on its other part has at least one groove adapted to the bead. In this context, the bead and the groove on opposite parts of the Be arranged plastic strip.

According to a preferred embodiment of the The present invention is the die cut line in shape formed at least one perforation line. On this way is a particularly smooth and reliable tearing or tearing of the Tear tab possible, the rest of the area reclosable opening of the bag Damage, for example due to unwanted Tear down, is safely protected.

To a variety of uses and Filling options with pourable goods too can ensure the wall of the bag expediently on its outside advantageously printable paper and on it Have plastic on the inside.

In particular, the provision enables at least one Plastic layer on the inside of the wall of the Bag that the plastic strip with the Inside of the wall of the bag in essential to the invention connected by sealing can be. Alternatively (or in addition) to this the plastic strip on the inside of the wall of the bag can also be glued on.

According to a particularly essential to the invention Further development of the present bag shows the preferably paper wall of the bag at least one outer layer and at least one Inner layer on. Here, the inside of the Expediently have an outer layer of paper and / or the outside of the outer layer with plastic be coated. Alternatively or in addition to this may have paper on the outside of the inner layer and / or the inside of the inner layer with plastic be coated.

In particular, the provision enables at least one Plastic layer on the inside of the inner layer of the bag that the plastic strip with the Inside of the inner layer of the bag in essential to the invention connected by sealing can be. Alternatively (or in addition) to this the plastic strip on the inside of the The inner layer of the bag can also be glued on.

According to a particularly advantageous development of the present invention are the at least two layers to hoses lying one inside the other, preferably to Square, rectangular or corrugated hoses, trained, preferably at least one Have longitudinal seam along which the at least two Layers at least in sections by gluing are interconnected.

In a preferred embodiment of the present invention has the bottom view of ground edges opposite each other in pairs formed flat bottom of the bag two towards each other and around two opposite floor edges folded bottom flaps that form a outer bottom flap and an inner bottom flap placed on top of one another and forming the Are glued to the floor.

If the present bag in particular to be developed in an inventive manner, so an embodiment is recommended in which the External location in the area of bonding the minimum two layers in at least one from the outside facing away inner part at least has at least one recess in places, in the the inside of the outer layer and / or the The inside of the inner layer is preferably direct rests on the outside of the inner layer.

By the at least one recess that the Outer layer of the bag in at least one of them Outside facing away from the inner part at least can have in places, the at least a recess in the area of the adhesive at least two layers (= outer layer and inner layer and optionally at least one between Outer layer and inner layer arranged intermediate layer; see. below), the inside of the Outer layer and / or the inside of the inner layer directly on the outside of the inner layer.

Since now both the inside of the outer layer as well each have paper on the outside of the inner layer can or can consist of paper ensures that when forming a longitudinal seam of the bag and / or in the formation of the bottom of the Bag not a direct concern of a paper having side of a layer of the bag on a with plastic coated side of a layer of Bag is done.

Thus, by laying paper on top of each other Paper the glue in between especially in the area of the longitudinal seams and / or the Bottom of the bag their unrestricted effect in unfold full temperature range, which a bag when storing or transporting for example of food or of Building materials may be exposed.

This will be the user of the Bag according to the present invention all the more appreciate than just the seams and the bottom, especially the latter, not infrequently due to being too heavy Contents are damaged, which mostly not only Uselessness of the bag, but also the loss of the goods to be stored or transported has the consequence. Such damage can be caused by the present bag reliably excluded become.

Regardless of this, it turns out to be pronounced useful if the inner layer in the area of Gluing both on the outside and on glued to the inside with the adjacent layers is because then it is a particularly firm and stable Formation of the longitudinal seams and / or the bottom of the Bag according to the present invention guaranteed.

In those known from the prior art Block bottom bags or block bottom bags or Kreuzbodenbeuteln is next to the longitudinal seams especially the formation of the soil, in particular the connection of the two bottom plates using Adhesive, with considerable problems been. Adequate progress in this regard To achieve, the inner layer of the outer Bottom bracket according to a particularly inventive Further training of the present bag at least a recess that at least partially with the recess in the outer layer of the inner Bottom bracket covers when the outer bottom bracket and the inner bottom flap to form the bottom are laid on top of each other.

This creates a direct contact between the Inside of the outer layer and the outside of the Inner layer accomplished, both the inside the outer layer as well as the outside of the inner layer can each have paper or even made of paper can exist, so that the provided in between Gluing in the form of an adhesive layer its full Can have an effect, making a convincing Stabilization of the state of the art vulnerable bottom area of the bag.

If you want a particularly good bonding of the outer Realize the bottom bracket with the inner bottom bracket, an embodiment is recommended in which the recess in the inner layer of the outer Bottom bracket not only partially, but also entirely the recess in the outer layer of the inner Bottom bracket covers when the outer bottom bracket and the inner bottom flap to form the bottom are laid on top of each other.

As stated above, the bags are according to the present invention often two layers, that is, with an outer layer and with an inner layer executed. Special applications where the Pouch to be transported is something special high weight or a particularly high Moisture content, but can Require bags with three or more layers.

This is the case with the bag according to the present invention in a preferred embodiment between the Outer layer and the inner layer at least one Intermediate layer arranged, expediently a Variant with exactly one intermediate layer between The outer layer and inner layer can be selected.

If this liner expediently completely is made of paper, it is recommended for Achieving particularly high stability and Tear resistance of the bag, the intermediate layer in the Area of gluing both on their outside as well as on the inside with the adjacent ones Layers to glue, as this will result in the adhesive the "paper on paper" edition is fully effective can unfold.

If you want the present invention in equivalent Way with the preferred embodiment realize one or more intermediate layers, so a configuration is recommended in which the Liner has at least one recess that yourself at least partially, preferably entirely of the recess in the outer layer. In addition this can also be provided that the Recess in the intermediate layer at least partially, preferably entirely with the recess in the Inner layer covers.

For the design of the recesses in principle, a multitude of possible forms are conceivable, these forms differ according to the intended use the type of adhesive application and according to Available space. In preferably at least one of the Recesses of round, oval, elliptical, square, rectangular and / or triangular Shape.

The same reference numerals in Figures 1 to 7C denote identical or similar components or Characteristics.

The bag 50 according to that in FIGS. 1 to 7C illustrated four embodiments of the present invention is a block bottom bag or Block bottom bag or cross bottom bag.

In its upper area, the bag 50 is one self-contained punching line 60 in the form of a Perforation line provided that an external, removable and strip-shaped Tear-off tab 70 forms (see FIGS. 1, 2, 3, 4A, 4B, 5, 6 and 7A).

After tear-off tab 70 (see FIG. 3) a plastic strip 80 is visible (see Figures 2 and 3), the inside of the outside Region of the tear-off tab 70 around the punching line 60 around with the inside 90i (see FIG. 2) of the Bag 50 is connected.

Furthermore, a known one is shown in FIG Reclosure of the plastic strip 80 shown. The reclosure has a bead 140 on a part 130 of the plastic strip 80, the one in a correspondingly shaped groove 160 on the other, part 150 of part 150 of the Plastic strip 80 used and there is held positively. By light pressure or by pulling lightly on this bead-groove connection this opens so that there is something in the bag 50 Well removed and the bag 50 after removal can be securely closed again.

In any case it can be seen on the bag 50 if this was already open, because in this The tear-off tab 70 is torn open (see FIG 3) or completely torn off so that the tear tab 70 is no longer available at least in some areas.

To a variety of uses and Filling options with pourable goods too ensure, the wall 90 of the bag 50th printable on its outside 90a (see FIG. 2) Paper and on its inside 90i (see FIG. 2) Plastic on. The provision of the Plastic layer on the inside 90i of the wall 90 of the bag 50 that the plastic strip 80 with the inside 90i of the wall 90 of the bag 50 by sealing (-> sealing seams 110; see FIG. 2) connected is.

Figure 4A shows a second embodiment of a Bag 50, the block or block bottom 120 still is not educated and one with itself closed punching line 60 in the form of a Perforation line is provided, the one external, removable and strip-shaped trained tear-off tab 70 forms.

The tear-off tab 70 hides a plastic strip 80 (cf. the above explanations on the Figures 2 and 3), the inside of the outside Region of the tear-off tab 70 around the punching line 60 around with the inside 901 (cf. The above explanations for FIG. 2) of the bag 50 connected is.

The bag 50 is constructed in two layers, that is Bag 50 has an outer layer 10 on the Laminated on the outside 10a a plastic layer and whose inside 10i is made of paper, and an inner layer 20, the outside 20a of paper has and the inside 20i with plastic is coated.

The outer layer 10 and the inner layer 20 are closed nested hoses formed like this not from the illustration in FIG. 4A, however from the representation of FIG. 7B for a comparable embodiment emerges (cf. in this connection also the explanations to Figure 7B below).

In the bottom view of FIG. 4A, the area of the according to Figures 5 and 6 to be formed flat floor by opposing each other in pairs Bottom edges 1202, 1204, 1206, 1208 limited, where along the two opposite one another Bottom edges 1202, 1204 folded bottom flaps 122, 124 that extend to their respective free End in sections along two at a time Fold in folding edges 1222, 1224, 1242, 1244.

Through a continuous dash-dotted line 4A is further a U-shaped area 30 marked, including the floor area of the two folded bottom flaps 122, 124 with one Adhesive layer is provided, which is a Floor glue for gluing the bottom flaps 122, 124 acts.

FIG. 4B shows a third exemplary embodiment of a Bag 50 shown, the block or block bottom is not yet formed and that is from the second Embodiment of Figure 4A essentially differs in that the inner layer 20 of the Bottom flap 122 in its central area Has recess 25 in the form of a punched out, the roughly the shape apart from a segment of a circle. The function of this recess 25 will be explained below.

FIG. 5 shows the bag 50 from FIG. 4B, wherein whose block or block bottom is partially formed.

Here, the bottom flap 124 is around the bottom edge 1204 folded, which shows that the Outer layer 10 of the bottom flap 124 in its central Area has a recess 15, which is also in Form a punched out and a similar shape to that described in Figure 4B Has recess 25.

In Figure 6, the bag 50 is from Figure 4B shown, the block or block bottom 120th is now fully formed.

For this purpose, the bottom flap 122 is around the bottom edge 1202 folded onto the bottom flap 124 so that the Bottom bracket 122 an outer bottom bracket and the Bottom flap 124 represents an inner bottom flap, glued together to form the bottom 120 are.

It is to be regarded as essential to the invention that by providing the recess 15 in the outer layer 10 of the inner bottom flap 124 and by the provision the recess 25 in the inner layer 20 of the outer Bottom flap 122 the inside 10i of the outer layer 10 directly on the outside 20a of the inner layer 20 is present since the recess 25 apart from the two segments of the circle almost entirely with the Recess 15 covers when the outer bottom tab 122 and the inner bottom flap 124 to form the Bottom 120 are stacked, as shown in Figure 6 is shown.

Since both the inside 10i of the outer layer 10 and also the outside 20a of the inner layer 20 in each case Exist paper, it is guaranteed that at the Formation of the bottom 120 of the bag 50 is not a direct one Concern of a page made of paper Layer 10, 20 of the bag 50 on the with plastic coated outer side 10a of an outer layer 10 of the Bag 50 is done.

At this point it should be noted that at the second shown in Figure 4A Embodiment of a bag 50 that the Recess 25 does not have, by the provision of Recess 15 in the outer layer 10 of the inner Bottom flap 124 the inside 20i of the inner layer 20 directly on the outside 20a of the inner layer 20 abuts when the outer bottom tab 122 and the inner bottom flap 124 to form the bottom 120 are placed one on top of the other, as shown in FIG. 6 is shown.

Figure 7A shows a side view of a fourth Embodiment of a bag 50 with a self-contained punching line 60 in the form of a Perforation line is provided, the one external, removable and strip-shaped trained tear-off tab 70 forms.

The tear-off tab 70 hides a plastic strip 80 (cf. the above explanations on the Figures 2 and 3), the inside of the outside Region of the tear-off tab 70 around the punching line 60 around with the inside 90i (cf. The above explanations for FIG. 2) of the bag 50 connected is.

The bag 50 is constructed in two layers, that is Bag 50 has an outer layer 10 on the Laminated on the outside 10a a plastic layer and whose inside 10i is made of paper, and an inner layer 20, the outside 20a of paper has and the inside 20i with plastic is coated.

The outer layer 10 and the inner layer 20 are closed nested hoses formed like this 7B shows a cross-sectional view shows along the section line A - A of Figure 7A. There it is the hoses shown in Figure 7B so-called corrugated hoses, these have each have a longitudinal seam 10l, 20l, along which the Outer layer 10 and the inner layer 20 by gluing are interconnected.

It is essential to the invention that the outer layer 10 in the area of the bond 30 (see FIG. 7C, the an enlarged cross-sectional view of the in Figure 7B circled area) of the two layers 10, 20 in one facing away from its outside 10a internal part has a plurality of recesses 17, in which the inside 10i of the outer layer 10 directly abuts on the outside 20a of the inner layer 20, wherein the inner layer 20 in the area of the adhesive 30 both on its outside 20a as well as on hers Inside 20i with the adjacent layers is glued. 7A shows that those trained in the form of die cuts Recesses 17 are of round shape.

Since both the inside 10i of the outer layer 10 and also the outside 20a of the inner layer 20 in each case Exist paper, it is guaranteed that at the Formation of the longitudinal seams 10l, 20l of the bag 50 no direct application of a page made of paper a layer 10, 20 of the bag 50 on the with Plastic coated outside 10a one Outer layer 10 of the bag 50 takes place.

Thus, by laying paper on top of each other Paper the intermediate adhesive 30 in Area of the interconnected longitudinal seams 10l, 20l of the bag 50 their unrestricted effect in unfold the full temperature range to which the bag 50 when storing or transporting for example of food or of Building materials may be exposed.

This will be the user of the Bag 50 appreciate all the more than with the The longitudinal seams 10l, 20l did not use conventional bags rarely been damaged by heavy content, which is mostly not just the uselessness of the Bag, but also the loss of the good to be kept or transported Episode. Such damage can be caused by the Bags 50 can be reliably excluded.

Finally, it should be noted that according to the present invention also a combination of the Refinements, features and advantages of the Figures 1 through 7C set forth four Embodiments can be provided in which Then drop the bag 50 both in terms of Bottom 120 as well as with regard to the longitudinal seams 10l, 20l of the inventive presented above Principle benefits.
