Definitions
- the invention relates to a pouring spout for film bags, comprising a pouring channel, the channel wall of the pouring channel being designed as a pouring spout at the first end area and the channel wall being surrounded by a welding area at the second end area, the welding area having two welding arms which extend in opposite directions to the channel axis of the Pouring channel extending in perpendicular directions to a respective welding arm end, in particular extending away from the channel wall in the second end region and each welding arm has a plurality of rib elements which are connected to the channel wall of the second end region and are spaced apart from one another in the direction of the channel axis and each rib element on a first Welding side has a first edge region extending between the channel wall and the end of the welding arm and, on a second welding side, has a second edge region extending between the channel wall and the end of the welding arm, wob ei the first and second edge regions form first and second welding zones.
- the edge areas/welding zones can be at least partially straight.
- Such spouts are known in the prior art, for example from publication DE 102017 009693 A1 from the same applicant.
- the spouts are intended to be welded between two layers of foil of a foil bag, e.g. a foodstuff, in particular a free-flowing foodstuff. Due to the converging shape of the edge areas forming the welding zones in both welding arms, the welding area has a shape that tapers from the axis of the channel towards the ends of the welding arm, in particular which is often also referred to as boat-shaped, with the tapering taking place in a plane perpendicular to the axis of the channel .
- the welding can be done thermally, for example, or inductively or by means of ultrasound, as well as other suitable welding processes.
- the welding sides are thus two opposite sides at the welding area.
- the weld sides lie on either side of a plane that includes the channel axis and both ends of the weld arm.
- the channel axis is the longitudinal axis of the pouring channel, which leads through the spout.
- This plane can also be referred to as a frontal plane and corresponds to a plane that lies parallel to the film layers of the film bag, in particular an unfilled film bag. The viewer actually sees the frontal plane when looking at the foil bag from the front.
- a removable closure e.g. a cap, is typically arranged on one end area, which in use with an upright film bag forms the upper end area in its function as a pouring spout, which is preferably attached or attachable and removable to the pouring spout with a threaded connection.
- the second end area forming the welding area is in the aforesaid Use the bottom end of the spout.
- a radially protruding collar can be arranged around the channel wall between the pouring spout and the welding area. This can serve as a stop for a cap and/or comprise functional components of a so-called originality, with which it can be indicated whether the cap has already been opened once, or at least whether it has been moved out of the originally closed position.
- the rib elements are preferably designed as flat elements.
- the thickness of such a surface element can be the same everywhere, but this is not mandatory for the invention. The thickness can also vary locally.
- the rib elements form the welding zones mentioned above, which run parallel to the upper edge of a film bag and thus ensure after welding that the film bag has several linear fastenings and seals on this upper edge along the welded-in welding area.
- the rib elements are subjected to forces acting parallel to the rib plane.
- a wall which connects all the rib elements, preferably with the wall around the aforementioned plane or Frontal plane is arranged around.
- the wall runs through the middle and perpendicularly to the rib elements, which results in two free spaces between each two adjacent rib elements, which are arranged on both sides of the partition wall.
- a pouring spout of the type mentioned at the outset which is also easy to produce using the injection molding process, in particular is easy to demould and which, with no or only insignificantly increased material costs, provides an increase in the area that can be used for welding in the welding area, in particular with at the same time sufficient stability of the required welding surfaces against the forces acting during the welding process.
- this object is achieved in that a single free space is formed in each welding arm between two adjacent rib elements, and each free space is open on one of the two welding sides, in particular open to the outside, and is closed with a welding surface on the other of the two welding sides .
- such an embodiment has at least two free spaces in each welding arm that are adjacent, in particular adjacent to one another, in particular if a respective welding arm has at least three rib elements that are arranged at a distance from one another.
- a preferred embodiment can provide that each welding arm has exactly three rib elements and this results in exactly two free spaces in each welding arm.
- the stabilizing wall described above which is central to the rib elements, is omitted. Instead of this a stabilization of two adjacent rib elements is achieved in that their welding zones, ie their edge areas, in the
- Channel extension direction are at least substantially one above the other, are connected by a weld surface.
- a welding surface thus extends between the welding zones of those two rib elements which surround the free space and, in addition to the stabilizing function, increases the total surface area available for welding. Compared to the previous line connection, this gives the weld greater resilience while at the same time ensuring the stability of the rib elements.
- the essential advantage of the invention is that, compared to the prior art, the entire welding surface is enlarged, preferably without having to use more or at least not significantly more plastic material in the injection molding process.
- the design according to the invention can be interpreted structurally in such a way that the originally existing wall described at the beginning was shifted from the middle between the previous welding zones partly in the direction of the first welding side and partly in the direction of the second welding side and the shifted wall area then forms a welding surface in each case.
- the welding surfaces can thus preferably be formed from the proportion of material that was occupied by the wall described in the prior art.
- each welding arm has at least one free space, in particular exactly one single free space, which is open on the first welding side and closed on the second welding side and has at least one free space, in particular exactly one single free space, which is closed on the first welding side and open on the second welding side.
- the at least one, preferably exactly one, welding surface closing a free space on the first side is offset in height (viewed in the direction of channel extension) to the at least one, preferably exactly one, welding surface on the other welding side.
- such an offset also occurs with the at least one opening of the free spaces on the welding sides mentioned, in particular via which the free spaces are open to the outside. Such an opening is later covered in use by a sheet of foil attached around the opening at the weld area.
- This design also ensures good demouldability during injection molding, because the mold projections on the injection mold that define the free spaces can be moved in a direction perpendicular to the aforementioned frontal plane when the injection mold is opened and closed.
- the invention can provide that the two welding arms are designed to be the same or identical in their respective geometry, in particular the relative arrangement of open spaces and closed spaces to one another on one and the same welding side, i.e. in particular they only differ on different welding sides.
- the invention can preferably provide that free spaces lying adjacent in the direction of the channel axis, in particular adjacent to one another, are alternately closed or open to the first and to the second welding side.
- this preferably results in the rib elements and the welding surfaces closing a free space having a meandering course.
- the direction of the spacing of the The sectional plane perpendicular to the welding arm ends is preferably at a distance from the channel axis, in particular such that the sectional plane lies outside the pouring channel. This results in an overall very stable construction with an enlarged welding area.
- the welding surface which closes a free space between the rib elements on one or alternatively on the other welding side, is arranged in such a way that its outward-facing surface, i.e. which comes into contact with the film layer to be welded, is flush with the edge areas of the welding zones forming the rib elements. This ensures that the welding surface and the welding zones of the edge regions adjoining it on both sides combine to form a jointly acting surface that is available for welding.
- a free space thus preferably extends, e.g. from the opening on one of the welding sides, which is bounded by the edge regions of the rib elements at the top and bottom, in a direction perpendicular to the frontal plane into the welding arm up to the inner surface of the welding surface on the opposite welding side.
- the opening can be delimited by a thickened area which extends in the direction of the axis of the channel and which is arranged on the inside on the opposite welding surface.
- the welding zones of the rib elements, the at least one welding surface closing a free space, and in particular also the above-mentioned thickening are preferably located on one welding side in the same plane, a welding plane in which the welding takes place.
- This plane may or may not be parallel to the channel axis. In a possible non-parallel design, the welding plane can move downwards away from the channel axis or closer to it.
- the invention can provide that the surface areas which come into contact with a foil layer during welding can have different surface finishes, in particular depending on the welding method used.
- the contacting surfaces are preferably at least the surfaces of the edge regions or welding zones, the welding surfaces closing the free space and a lateral surface area which surrounds the channel axis and connects the surface areas of the welding arms.
- These contacting surfaces can, for example, be smooth, in particular without structuring, preferably in the case of a conductive introduction of welding energy.
- these contacting surfaces can also have a rough design, in particular with a structure, preferably one that provides initial points for the melting due to the structure, such as projections, preferably in the case of ultrasonic welding.
- a structuring can be arranged e.g. in a certain dimension range, in particular from 0.02-0.05 mm, raised on the contacting surface.
- An expansion of the free space in the direction of the spacing of the ends of the welding arms can preferably already be present in that the welding arms taper in the direction of the ends of the welding arms.
- a preferred embodiment can provide for each of the rib elements to be arranged around a transverse plane which is perpendicular to the channel axis.
- the transverse plane and the frontal plane mentioned at the outset are preferably perpendicular to one another.
- the transverse planes of different rib elements are thus spaced apart from one another.
- the surface of a rib element pointing into the free space is inclined to the transverse plane around which the rib element is arranged. Fliering can achieve the above-mentioned expansion of the free space in the direction of its open side, and demouldability can be facilitated.
- a further preferred embodiment can provide that on the rib element closest to the second end of the pouring channel, in particular the bottom rib element, a collar pointing away from the rib element and enlarging the welding zones/edge areas of this rib element is formed. Since the bottom rib element has no further adjacent rib element below, its welding zone would be limited to the thickness of its edge area.
- the molded collar extends downward in line with the sweat zone.
- the welding zone of the ribbed element is preferably enlarged at least essentially by the height of the collar, ie in particular the ribbed element is thickened at the edge towards the bottom. This leads to an improved resilience of the welded connection between the welding area and the film layer, precisely at the point where there is the greatest movement between the film layer and the welding area in the application.
- the collar can form an elastically compliant area which can prevent stretching of the film in this area during welding. It is particularly preferred if the collar has a chamfer on its lower edge pointing outwards or is rounded with a radius. This can also keep stress away from the film.
- the thickness of at least one rib element, preferably of all rib elements, viewed in the direction of the channel axis increases in the direction towards the end of the welding arm and/or in the direction of the channel axis considered fleas of a free space between two rib elements is decreasing.
- Equally arranged free spaces on the same welding side are preferably closed or open in both welding arms with respect to their position relative to the channel axis as viewed in the direction of the channel axis.
- two identically arranged free spaces can be connected by means of a groove via the lateral surface area of the second end area, which extends between the two welding arms.
- their fleas measured in the direction of the channel axis correspond to the fleas of the free spaces in the same direction.
- this lateral surface area is designed without a groove, in particular the lateral surface area on which there are two free spaces in the different arms has a curved surface profile which corresponds to the surface profile between the welding surfaces of both welding arms closing the free spaces on the same welding side.
- a design that is also preferred in terms of construction provides that in the welding area of the pouring channel there are two planar/flat channel wall areas which are parallel to one another and lie opposite one another around the channel axis and to which the rib elements of the two welding arms (3a, 3a) are connected.
- the planar, planar shape is therefore at least on the side of the duct wall on which the rib elements adjoin.
- the planar, flat surface of the duct wall thus points into a free space. Demoulding during injection molding preferably takes place in a direction parallel to this surface.
- the duct wall can also be different radially inward to the duct axis be designed as planar, although it is preferably designed there as well.
- the pouring channel can preferably have several stiffening ribs in the welding area between the two mutually parallel, opposite channel wall areas, which extend radially inwards from the inner surface of the channel wall.
- the inner surface of the channel wall between the parallel, planar channel wall areas can be curved, in particular with a fixed radius to the channel axis.
- the welding surfaces closing a free space are arranged projecting outwards in relation to at least one bordering area, preferably in relation to the two bordering areas of the rib elements.
- Such a protruding welding surface is preferably flat at least in regions, in particular at least in the region extending from the lateral surface region of the second end region to the end of the welding arm, or has a curvature running in the direction of the spacing of the edge regions, in particular a curvature that bulges outwards.
- Such protruding welding surfaces can, for example, form a supply of welding material that is pressed during welding, in particular up to the edge areas.
- An embodiment can also provide that the welding surfaces closing a free space are arranged in alignment with at least one bordering area, preferably with the two bordering areas of the rib elements.
- the welding surfaces and/or edge regions are flat, at least in the region extending from the lateral surface region of the second end region to the end of the welding arm, or in a direction perpendicular to the channel axis Have level running curvature.
- Such a curvature can be designed in such a way that the welding surfaces and edge regions are designed to be outwardly concave or outwardly convex in the plane considered.
- FIGS. 1 to 4 show a first preferred embodiment which, apart from the differences mentioned later, has features in common with all other embodiments of the figures, which are then not described again in the later figures.
- the figures show the features according to the invention in different views.
- the spout shown has a pouring channel 1, which has a longitudinal extension direction according to the channel axis 1b and its Channel wall 1a is formed in an upper end region 2a at least substantially with a circular-cylindrical cross-section and forms a pouring spout.
- the channel wall 1a has an external thread on the outside, which interacts with a cap with a corresponding internal thread, which is not shown here and is immaterial to the invention, so that the pouring spout can be optionally closed or opened.
- the pouring spout is the area that can be covered by the cap and from which the contents of a foil bag (not shown here) can be removed.
- the channel wall 1a is surrounded by a welding area 3, which comprises two welding arms.
- the surrounding channel wall does not have to correspond to the circular-cylindrical shape that can be seen in the upper area.
- the welding area 3 comprises two welding arms 3a and 3b, which are arranged diametrically opposite one another around the duct wall/the duct axis and extend in opposite directions away from the duct axis 1b/the duct wall 1a.
- a film layer of a film bag is welded to the welding arms 3a and 3b on two opposite sides 6a and 6b, so that the welding area is enclosed between the film layers.
- the welding sides 6a and 6b lie on both sides of an imaginary frontal plane which includes the channel axis 1b and both welding arm ends 4a, 4b. The frontal plane is thus in the center of the spout and is parallel to the film layers of a film bag (not shown).
- each welding arm 3a, 3b comprises several, here three, rib elements 5a, 5b, 5c.
- the possible designs are not limited to the three rib elements shown. In particular, more than three rib elements can also be provided, which only analogously lengthens the design downwards.
- the rib elements are preferably designed as flat elements and each extend around a transverse plane 10a, 10b, 10c is perpendicular to the channel axis 1b.
- the rib elements 5a, 5b, 5c or their transverse planes 10a, 10b, 10c are spaced apart in the direction of the channel axis 1b.
- every two adjacent rib elements 5a and 5b or 5b and 5c enclose a free space 8a and 8b.
- This respective free space 8a, 8b occupies the space between the mutually facing surfaces of the rib elements 5a, 5b, 5c, so in particular the respective free space is in the interior of each welding arm 3a, 3b.
- the free spaces 8a, 8b occupies the space between the mutually facing surfaces of the rib elements 5a, 5b, 5c, so in particular the respective free space is in the interior of each welding arm 3a, 3b.
- each rib element 5a, 5b, 5c has an edge region 7a or 7b on both welding sides 6a, 6b.
- the edge region 7a, 7b extends at the outer edge essentially over the height (viewed in the direction of the channel axis 1b) of the rib element 5a, 5b, 5c.
- This edge region 7a, 7b in particular its end face pointing outwards, forms a welding zone which is used alone or with enlarged areas for welding to a foil layer.
- the perspective view of FIG. 1 makes it clear that the edge areas 7a, 7b or the welding zones converge towards the end of the welding arm. In particular, this results in a boat-like shape of the welding area.
- FIG. 4 makes it clear that the rib elements 5a, 5b, 5c are connected in one piece to the channel wall 1c in the lower end region 2b.
- each of the two adjacent free spaces 8a, 8b lying one above the other is open only to exactly one of the two welding sides 6a, 6b and is closed to the other with a welding surface 9 which covers the ones lying one above the other Connects edge areas and enlarges their welding zones.
- the upper free space 8a in both welding arms 3a, 3b is open towards the welding side 6b and is closed with a welding surface 9 towards the welding side 6a.
- the lower free space 8b is open to the welding side 6a and is closed with a welding surface 9 to the welding side 6b.
- the design in both welding arms is therefore identical on the same welding side. If there are more than two free spaces one below the other, these are preferably closed or open alternately in the direction of the channel axis to one welding side and the other.
- the welding area 3 is therefore not mirror-symmetrical about the frontal plane.
- a shaped projection for forming the free spaces 8a, 8b therefore dips into the spout during injection molding with reference to Figure 2 for the upper free space 8a from the welding side 6b in the direction of the welding side 6a up to the inner wall of the upper welding surface 9 and for the lower free space 8b from the welding side 6a towards the welding side 6b up to the inner wall of the upper welding surface 9 into the spout.
- the demoulding can thus take place perpendicularly to the direction in which the welding arm ends 4a, 4b are spaced apart.
- the respective free space 8a, 8b is continuous on the inside from the welding surface 9 to the opposite opening and preferably it widens in this direction.
- the thickness of a welding surface 9, viewed perpendicularly to the frontal plane, is preferably smaller than the thickness of the thickest rib element 5a, 5b, 5c, viewed in the direction of the channel axis 1b.
- the term "weld surface” is preferably used not only for the Welding understood functional surface, but the wall element with this functional surface.
- FIG. 3 shows a meandering course in the sequence of rib elements 5a, 5b, 5c and welding surfaces 9 resulting from the offset of the welding surfaces 9 or the openings of the free spaces 8a, 8b the meandering course continues.
- the radially projecting collar shown is preferably arranged around the channel wall 1a, which can serve as a stop for a cap and carries functional elements of an original nature.
- the free spaces 8a, 8b in the plane of the opening to the outside preferably have the same fleas everywhere.
- the lowermost rib element has a downwardly projecting collar 11, in particular which also serves as a downward enlargement of the weld zone and/or dissipates load stress from the film at this point due to increased compliance.
- a collar can also be omitted in other designs.
- FIGS. 5 and 6 show, with otherwise identical features, a second embodiment according to the invention in which this groove 13 is missing.
- the lateral surface area 12 has the same curved course at the level of the openings of the free spaces as at the level of the welding surfaces, which close the other free spaces on the same welding side.
- FIGS Clearances 8a, 8b decreases in the direction of the welding arm ends 4a, 4b.
- Figure 8 in particular shows that in this embodiment the area effectively available for welding increases in the direction of the welding arm ends 4a, 4b, in particular as a result of which, in the projection perpendicular to the frontal plane, there is an increased overlap 14 of the welding sides 6a, 6b opposite welding surfaces 9 results in comparison to the other versions.
- Figure 9 shows a bottom view of the spout common to the previous versions with collar 11, which shows that the channel wall of the pouring channel in the lower end area 2b has two parallel, opposite, planar/even walls 1c, to which the rib elements are connected, of which here the bottom 5c is visible.
- stiffening ribs 14 run radially inwards towards the duct axis 1b.
- the pouring channel 1 transitions from a cylindrical inner shape to the shape with the planar, parallel walls 1c at a step 1d, which is at the level of the collar with the originality function.
- the invention is not limited to the shown inner shape of the pouring channel 1 in all possible embodiments.
- Figures 10 and 11 show views of an embodiment in which the collar 11 described above is not present.
- the welding area 3 ends downwards with the lower surface of the lowermost rib element 5c. Otherwise, all the other features described above can also be realized in this embodiment, in particular with groove 13, as shown here, but also or without groove 13.
- All figures show designs in which the edge regions 7a, 7b of the rib elements 5a, 5b serving as welding zones and/or the welding surfaces 9, which close the free spaces 8a, are preferably arranged flush with one another, in the extension to the end of the welding arm 4a, 4b, at least in certain areas are extended in a straight line, in particular between the respective arm end 4a, 4b and the curved lateral surface area 12.
- the welding zones In the area between the connections of the rib elements 5a, 5b to the two channel walls 1c of the second end area 2b, the welding zones, possibly enlarged by the welding surfaces 9 closing the free space, merge into one another, preferably continuously, by means of the convexly curved outer surface area 12 mentioned.
- the invention can also provide for all shown and generally for all possible non-shown embodiments according to the invention that the edge regions 7a, 7b, in particular including the welding surfaces 9 that close the free space, are designed with a curved course, in particular between the welding arm ends 4a, 4b and the lateral surface areas convexly curved outwards 12.
