description

The invention relates to a pouring system for a packaging system comprising an inner bag, a sturdy casing and a spout.

In the present invention is a special Ausgusssystem for z. As in the German patent application no. DE 1 0 201 0 01 1 208.9 (PCT / EP201 1/001 1 52) described packaging system. This consists of an inner bag, a sheath of a stable envelope (eg., Carton) and a spout that protrudes through the outer sheath through. In this system, the bag is completely closed and can therefore be filled aseptically. Thus, a mechanism is needed that opens the bag, at the point provided in the spout, just before consumption and releases the contents. To bag production also very simple materials such. As so-called PE, PET or OPP to use films that are often very elastic, the slicing or opening of the bag, as the prior art claims it would require a lot of power and a controlled due to the often very tough structure of the films Opening would not be guaranteed. So z. B. only a part of the cut opening, release the contents or it could even fall in part of the film in the medium. Therefore, there is a high interest in this invention to circumvent this problem.

The object of the present invention is to overcome the disadvantages of the prior art. The object underlying the invention is achieved in a first embodiment by a pouring system for a packaging system comprising an inner bag, a sturdy casing and a spout, characterized in that the base of the spout and the inner part of the spout are connected to the bag , An advantage of the present invention is that not only the base of the spout is connected to the bag (for example, welded, glued), but also at the same time the consumer to be removed or openable part of the closure, such. B. a pull ring (pull ring) but also a tear-off or rotating system, separately connected to the bag (for example, welded or glued), so that when removing the opening on the spout also the intended, preferably pre-perforated part of the film is removed with ,

Preferably, the inner part of the spout on its side facing the film of the bag to at least 70%, most preferably at least 90% of the surface, in particular completely, is materially or non-positively connected to the film of the bag. Particularly preferably, the inner part of the spout is glued to the Fol ie the bag, in particular glued over the entire surface. This can be particularly effectively prevented that a part of the film of the bag falls into the contents. The spout preferably has an outstanding part, which is in particular a spout.

The inner part of the spout is preferably inside of the projecting part of the spout, in particular the spout. The inner part is formed flat on the side facing the film of the bag. So you can connect the inner part of the spout better with the film of the bag.

The spout has on its outer wall a thread which engages in particular in a mating thread of the spout cover.

Preferably, the base of the spout is positively or positively connected to the enclosure. This connection is preferably a deadlock. Most preferably, an integrally formed on the base or the envelope projection is jammed with a recess in the enclosure or the base. The connection is preferably circular. Alternatively, the compound can also be cross-shaped, serrated, angular or round, depending on which film is used and what are the requirements for the connection of the inner bag with the outer casing.

The inner part of the spout preferably has a pull ring or pull ring, the pull ring particularly preferably having an outer diameter of at most 98%, in particular at most 90%, of the inner diameter of the protruding part of the spout, in particular of the spout. So you can introduce a welding tool such as a welding tube or a welding punch between the pull ring and the inner wall of the spout to weld the inner part of the spout to the film of the bag and / or produce a predetermined breaking point between the inner part of the spout and the base or Ausgußstutzen.

Namely, a predetermined breaking point is preferably provided between the inner part of the spout and the base or pouring spout. At the predetermined breaking point, the material is either less thick and / or degraded, for example, by the effect of heat. Through this breaking point, the connected to the inner part of the spout Fol ie the bag can be removed and the contents can be distributed from the packaging. The pull ring or pull ring is usually arranged on the side facing away from the film of the bag side of the inner part of the spout.

At the spout and in particular at the protruding part of the spout, a spout is preferably arranged. Preferably, on the spout cover also a, attached at 1 to 1,000 points, mounted press ring, which engages, for example, when attaching the lid in a notch, or is connected in any other way. Preferably, the sheath is clamped between the spout base, which is preferably provided with small protruding pyramids, and the pressing ring. As soon as the lid is screwed on, the connection between press ring and lid breaks off. The press ring thus continues to ensure the jamming of the envelope.

From the prior art spouts with cutting mechanisms or Aufreißmechanismen are known which are usually ien or other additional material, composite material or thicker foils connected. The disadvantage of these systems is that often higher costs are incurred, that recycling is not easy, or even impossible, and that aseptic filling is thus not possible.

With the present invention preferably simple elastic films such as PE, PET or OPP can be used for bag production.

Typically, these films require in the prior art much force when opening the packaging, the opening, for example, runs uncontrollably, so that when pouring the discharge of the contents is very difficult to control or possibly parts or remnants of the Fol can fall into the medium.

The targeted connection of the bag, which preferably also has a pre-perforation at the outlet level, with a preferably herauszubrechenden inner part of the spout base, such as a known in the industry as pull ring system part, or one to be removed by turning mechanism inner part is targeted only the part of the bag with removed, which corresponds to the inner part of the spout or the opening mechanism.

After preferably welding the film to the base, filling and closing the bag, it can be placed in the stable wrapper (e.g., carton). The upper flaps of the enclosure are preferably folded and the recesses in the middle of each flap allow the spout to protrude. Subsequently, the base cover is preferably turned up with a robot. This lid preferably has a pressing ring which presses the tabs of the envelope against the base bottom. Preferably, protruding pyramids are arranged on the upper side of the base, which reinforce the support of the base to the enclosure and absorb the torque when turning the lid. If the lid is then opened, the pressing ring preferably remains on the base and further compresses the envelope with the base, so that a sliding down of the spout is prevented with the bag down and the spout continues to protrude through the enclosure.

This spout system saves material costs, allows the recycling of all components of the packaging and aseptic filling. The wrapper may be a carton.

The inner part of the spout may have a pull ring, a tear-off tab and / or a rotation system, which is removed or opened by the consumer, for example.

Upon removal or opening of the interior of the spout (eg, a pull ring, a trailing tab, or a rotation system), the bag is preferably opened at the desired location of the spout to release the contents.

Preferably, the bag is pre-perforated at the point of the spout.

Preferably, contents can be filled aseptically. The spout cover is preferably equipped with a press ring fixed to, for example, 1 to 1000 points. Preferably, this connects or presses, after snapping, or other mechanism, the spout base and the enclosure firmly together, so that even after opening the spout cover, the spout base and the enclosure remain firmly connected.

The spout base is preferably provided with small protruding pyramids that receive the torque when the lid is rotated.

Preferably, the pyramids are arranged on the surface of the spout base facing the casing.

On the spout cover is preferably on the inside of a driving element, more preferably a mandrel or hook, arranged, which interacts with the inner part of the spout, particularly preferably the pull ring, and at least partially removes the inner part of the spout upon rotation of the spout. This has the advantage that the bag when turning the lid by the removal of the inner part of the

Can open spout. This only works if the bag is connected to the inside part of the spout.

The driving element can also be preferably connected to the inner part of the spout. This can be realized via a web.

But particularly preferably, a pull ring is formed on the inner part of the spout, which is also connected to the inside of the spout cover. The connection of the pull ring with the inside of the spout cover is preferably a predetermined breaking point. This predetermined breaking point between the outlet cover and the pull ring is preferably somewhat weaker than the predetermined breaking point between the inner part of the spout connected to the bag and the base or pouring spout. As a result, the inner part of the spout connected to the bag film can still be removed by hand if the rotation of the cover has not been sufficient, since, for example, the pull ring loosens more easily from the cover than the inner part of the spout from the base or spout.
