Definitions
- the invention relates to a stand-up pouch made of a heat-sealable or weldable plastic film for holding liquid or pasty material with two side walls and a pouring element which can be brought from a basic position into an overturned pouring position.
- Such a bag is already known from EP 0 010 357.
- the known bag also has two side walls and a bottom and a top part, a pouring element being inserted between the top part and the side wall.
- the pouring element can be tipped forward to pour out the filling material and has means for stabilizing and holding the closure element in the forward-tipped position. From the folded position, liquid can be poured out safely and easily through the closure element even with very full bags, without the bag having to be tilted too much.
- such bags have the disadvantage that, when the pouring element is in its basic position, e.g. in its upright position and the bag e.g. to open the pouring element is firmly gripped by one hand, liquid unintentionally emerges from the pouring element and is spilled.
- the object of the present invention is to provide a stand-up pouch which is improved in terms of handling and to prevent liquid from inadvertently escaping from the open stand-up pouch.
- this object is achieved by a closure film which is fastened to the pouring element between the side walls and projects into the interior of the bag such that it lies against a side wall in the basic position of the pouring element and thus closes the inlet to the pouring element and in a tilted pouring position of the pouring element from the Side wall protrudes and releases the inlet to the pouring element. Due to the fact that the sealing film is in the basic position, for example the upright position, of the pouring element on a side wall and thus closes the inlet to the pouring element, for example, when a stand-up pouch is opened and firmly enclosed by one hand, no more liquid can be inside the pouch pushed up and spilled through the pouring element.
- the sealing film in the upper region corresponds at least to the width of the pouring element, so that the inlet to the pouring element can be closed well by the sealing film.
- the material of the sealing film preferably corresponds to the material of the inner film of the multi-layer plastic film. This has the advantage that the sealing film lies better on the side wall. Because the sealing film protrudes into the inside of the bag, i.e. can also come into contact with the filling material if it has the same properties as e.g. Have temperature resistance, food compatibility etc. as the inner film of the stand-up pouch. ,
- the sealing film is preferably a monofilm made of polyethylene and has a thickness in a range from 150 ⁇ m to 300 ⁇ m, preferably about 200 ⁇ m.
- the sealing film has at least one surface-treated roughened surface, which e.g. has undergone corona treatment.
- a surface treated in this way lies even closer to the side wall.
- the two side walls are connected to one another at their longitudinal edges, a foldable bottom part, which serves as a stand, and which is located between the side walls, is arranged at the lower end of the stand between the lower transverse edges and a foldable cover part is located at the top end of the stand between the side walls , and the pouring element is inserted between a first side wall and the ceiling part.
- the length of the first side wall can be greater than the length of the second side wall, so that the pouring element comes to lie above the lower transverse edge of the second side wall.
- the sealing film is advantageously welded between the pouring element and the ceiling part.
- the sealing film can also be welded between the ceiling part and the first side wall, preferably along the outer sealing seams. This has the advantage that the sealing film can simply be inserted and welded in without welding during the welding of the ceiling part and the first side wall.
- the sealing film is rounded in the lower area. In this way, the sealing film can fit particularly well and close to the corresponding side wall.
- FIG. 1 shows the components of the stand-up pouch according to the invention in an exploded perspective view according to a preferred exemplary embodiment of the present invention
- FIG. 2 shows the front view of the stand-up pouch shown in FIG. 1,
- FIG. 3 is a sectional illustration along the line III-III of FIG. 1,
- FIG. 4 shows a side view of the stand-up pouch cut longitudinally along the line IV-IV in FIG. 1,
- FIG. 5 shows a plan view of a container cut along the line V - V of FIG. 2 in the form in which it is filled when it is filled,
- FIG. 6a shows a schematic side view of the filled bag shown in FIG. 2, the pouring element of which is in a basic position
- FIG. 6b shows the stand-up pouch shown in FIG. 6a, the pouring element of which is in an overturned pouring position
- FIG. 6a shows a schematic side view of the filled bag shown in FIG. 2, the pouring element of which is in a basic position
- FIG. 6b shows the stand-up pouch shown in FIG. 6a, the pouring element of which is in an overturned pouring position
- FIG. 7 shows the components of the stand-up pouch according to the invention in a perspective exploded view according to a further exemplary embodiment of the present invention.
- the stand-up pouch comprises a first side wall 2, a further side wall 3, a base part 10 serving as a stand base and a cover part 11.
- the bottom and cover part comes to lie within the contour of the side walls when the bag is connected. These parts then unfold accordingly when the container is filled.
- a ceiling part tab 15 is formed here.
- the side wall flap 14 is likewise formed in one piece with the side wall 2 and that corresponds to the ceiling part flap 15.
- the heights of the side walls 23 are the same in this exemplary embodiment, but the height of the side wall 3 can be smaller than the height of the side wall 2.
- the stand-up pouch also has a closure film 25 and a pouring element 20.
- the pouring element 20 can be closed, for example, via a screw closure, not shown.
- the bag can thus easily be closed again if it has not been completely emptied after use.
- the individual parts are connected to one another to produce the bag.
- the longitudinal edges 4 and 5 of the side wall 3 are sealed with the longitudinal edges 6 and 7 of the side wall 2 along the areas shown in dashed lines.
- the base part 10 is welded across the hatched four corner areas 10a, b, c) to the four corner areas 3c, 2a, 2b of the side walls 2 and 3, for example in the manner of a triangle and at the corresponding hatched transverse edges.
- the cover part is sealed with the respective side wall 3 via sealing seams 30, which extend from both ends of the longitudinal edges 4, 7 obliquely to the removal opening 12 into which the pouring element 20 is inserted, or obliquely to the transverse edge 31 of the second side wall 3, 2 connected.
- the oblique edges 30a of the side wall 3 are sealed to the oblique edges of the ceiling part 30b and the upper transverse edge 22 of the ceiling part 11 is welded to the upper transverse edge 31 of the side wall.
- the cover part 11 can also be formed in one piece with the second side wall 3.
- the inclined edges 30c of the cover part 11 are welded to the inclined edges 30d of the first side wall 2 and the intermediate edge 25a of the closure film 25 and thus form the outer sealing seam 30. Between the flap 15 of the cover part 11 of the flap 33 and formed in the closure film 25 the tab 14 of the first side wall 2, the closure element 20 is sealed.
- the side walls 2 and 3 are provided with spaced-apart, outwardly directed longitudinal embossments 21, which cause the filled bag to take a shape in plan view, cut along the line V - V in FIG. 2, as shown in FIG. 5. Furthermore, in a region below the pouring element, the bag has a device for stabilizing and holding the pouring element in the upturned pouring position, here in the form of an embossing 40.
- the embossing 40 is, however, not absolutely necessary for the present invention, since the closure film also stabilizes the position of the pouring element in the upturned pouring position. This embossing is not shown in FIGS. 2 and 6.
- Figures 3 and 4 accordingly show the longitudinally cut shapes of the stand-up pouch.
- the closure film 25 is aligned essentially parallel to the side walls 2 and 3.
- the closure film 25 is welded along the oblique side edges 25a and the longitudinal edges of the tab 33 of the closure film 25 between the corresponding oblique edges 30c and 30d of the ceiling part and the first side wall 2 and the respective longitudinal edges of the tabs 15 and 14. This is advantageous since no separate process step for inserting the closure film 25 is necessary.
- the longitudinal edges 25b of the closure film 25 are not welded to the bag, but can also be welded in between the longitudinal edges 4 and 6 of the side walls.
- the sealing film 25 is connected to the pouring element 20, it can follow the tilting movement of the pouring element 20, so that the lower transverse edge 25c moves at least in the central region in the direction of the arrow R, i.e. away from the first side wall 2 when that Pouring element 20 is moved forward into a tilted pouring position.
- the sealing film 25 is spaced further apart from the second side wall 3 than from the first side wall 2.
- closure film 25 projects with its lower transverse edge 25c at least 20% and preferably at least 35% of the bag height into the inside of the bag, the distance between the lower bag edge 8, 9 and the upper edge 16 of the pouring element being considered as the bag height.
- the sealing film of a 1 liter bag protrudes at least 8 cm into the inside of the bag.
- the basic position is understood to mean the position of the pouring element 20 in which no filling material is to be poured from the stand-up pouch and in which e.g. the longitudinal axis L of the pouring element runs essentially parallel to the longitudinal axis I of the stand-up pouch 1.
- the basic position can also be understood to mean a position in which the longitudinal axis I of the pouring element 20 is oriented at a small angle, for example ⁇ 45 ° to the longitudinal axis I of the stand-up pouch 1 to the side walls 2, 3.
- the closure film 25 projects into the inside of the bag in the basic position.
- the pouring element 20 is then tilted into a pouring position in the direction of arrow D, as shown in FIG. 6b, in which the longitudinal axis I of the pouring element 20 at an angle of approximately 70 to 100 °, preferably 90 °, to the longitudinal axis I of the stand-up pouch in the direction is inclined to the first side wall 2, the sealing film 25 simultaneously moves in the direction of the arrow R, ie away from the front side wall 2, and exposes the inlet Z to the pouring element 20. This means that filling material can run out of the inside of the bag through the pouring element.
- the plastic film used for the side walls 2, 3, the top part 11 and the bottom part 10 is preferably a multi-layer film, in this exemplary embodiment, for example, a three-layer film, the outer film of which faces outwards, e.g. a PET film with a thickness of e.g. 12 microns, the middle film is a PA film with a thickness of z. B. 15 microns and the inner film is a PE film with a thickness of about 180 to 200 microns.
- the material of the sealing film 25 is selected in accordance with the material of the inner film, i.e. that in this exemplary embodiment the sealing film 25 is also a PE film and has a thickness of 150 to 300 ⁇ m.
- At least the side of the closure film 25 which faces the first side wall 2 has been subjected to a surface treatment, for example a corona treatment, in order to roughen the surface and thus to improve the adhesiveness of the closure film 25 to the side wall surface 2.
- FIG. 7 shows a further embodiment of the present invention, which corresponds to the exemplary embodiment shown in FIGS. 1 to 6, with the exception that the closure film 25 is rounded at its lower end, which faces the bag bottom.
- the lower transverse edge 25c runs from the two side edges 25a, not parallel as in FIG. 1, but has a rounded shape, e.g. a semi-oval shape. Such a rounded transverse edge allows the sealing film 25 to lie even better against the corresponding side wall.
