Definitions

• the invention relates to a device for opening and reclosing containers, in particular flat gable composite packs, with a pouring opening, a pouring spout formed thereon and a base element surrounding the pouring opening for fastening the device to the surface of the container, a lid hinged to the base element and one opening element connected to the lid, the opening element being movably arranged in a guide in the lid such that the opening element is pierced by the opening element through the pouring opening in the base element during the opening process, and the use of such a device with a flat gable composite pack and for application flat gable composite packs prepared for this device.
• Rectangular flat gable composite packages are known in many copies. They are mainly used in the field of liquid packaging in connection with cold, cold sterile, hot and aseptic filling. As a rule, these packages cannot be closed again after opening them once. It has therefore already been proposed in flat gable composite packs of the aforementioned type to arrange a pouring element on the packing gable, which is equipped with a corresponding lid ⁇ EP 0 577 865 AI). In the area of the cardboard layer and outer PE layer of the composite material, a circumferential dividing line is provided for weakening the gable material, into which an opening element connected to the lid and corresponding to the shape of the circumferential dividing line is pressed into the packaging material to open the pack.
• the pouring opening is opened by opening the lid, the opening element and the package composite located thereon being opened together.
• This known device is disadvantageous in that, particularly in the case of fruit juices containing sugar, when the lid is opened on the package opened with the lid, due to the irregular tear edges of the PE film, drops in the contents of the package can get stuck and then drip down onto the table or floor during the pouring process can and thus reduce the functionality of the known device.
• the reclosing of the device due to the irregular tear edge of the PE film and a corresponding jamming in the pouring opening when closing the lid can lead to leaks.
• the torn-out package composite gives the package with the lid open an unsightly appearance.
• the present invention is therefore based on the object of opening and opening the device
• a device which is characterized in that the opening element is designed in two parts and consists of a pressure plate and a piercing ring and that the piercing ring remains in the base element after opening.
• this device can be realized with any flat gable composite packs, but it is particularly expedient for safe handling if the flat gable composite pack, to which the device according to the invention is to be applied, has a weakening line arranged in the area of the later pouring opening and corresponding to the contour of the opening tube is provided.
• a flat gable composite package with a recess in the carrier layer which is arranged in the region of the later pouring opening and corresponds to the contour of the opening tube and is sealed with at least one PE layer
• the pressure plate has at least one circumferential web on its underside for receiving the piercing ring, such a web being able to be arranged both inside and around the outside of the piercing ring.
• a circumferential web on its underside for receiving the piercing ring.
• two concentrically arranged webs are also conceivable, the spacing of which corresponds precisely to the thickness of the piercing ring.
• An alternative teaching of the invention provides that the pressure plate has a circumferential groove on its underside for receiving the piercing ring.
• the cover has at least one stop for limiting the movement of the opening element. In this way it can be reliably ruled out that the opening element leaves the guide of the lid when pressed into the composite material and reaches the inside of the pack. Another stop can fix the opening element in the "transport position", ie in the non-pressed state, in the cover.
• the piercing ring of the opening element has teeth arranged in a ring-like manner as an opening aid.
• teeth arranged in a ring-like manner as an opening aid.
• the push-through ring remains in the region of its open position in the base element and when the cover is opened, the pressure plate separates from the push-through ring, so that the pressure plate then remains in the cover.
• the piercing ring has clamping elements on its outer surface, which can be designed, for example, as projections and / or beads.
• the cover is connected in an articulated manner to the base element, as is already known per se from the prior art mentioned in the introduction to the description.
• the articulated connection has means for locking the lid in its open position. This is particularly expedient since an "automatic closing" of the lid during the pouring-in process can be reliably ruled out and in this way the liquid can flow out freely through the pouring spout of the base element.
• cover and the opening element used therein have a flush surface in the transport position. This type of design offers the consumer an aesthetic impression and avoids dust or dirt accumulated above the opening element.
• the pouring opening and the piercing ring have a round cross section. In this way it is also reliably ensured that when the Opening element by central finger pressure the force used is evenly used to open the Verbundmate ⁇ als.
• the base element, the cover and the opening element are preferably made of plastic.
• the base element and the lid can be produced in one piece using the injection molding process, and the opening element to be inserted into the lid before application with the flat gable composite pack can be manufactured separately in two parts.

• the opening element inserted into the cover 2 in the normal state and designated 3 in the further figures has been dispensed with in FIGS. 1 to 3.
• the base element 1 has a pouring opening 4, and is hingedly connected to the cover 2 by means of a hinge tape 5A injection molded in one piece.
• the articulated connection takes place next to the actual hinge strap 5A by a locking element 5B arranged in the central region of the strap, which is provided for locking the cover 2 in its open position.
• a pouring spout 6 starting from the pouring opening 4 serves as a pouring aid, ie for reliably overcoming the liquid from the packing edge (not shown).
• FIG. 3 clearly shows that when the cover 2 is closed, the pouring spout 6 is completely closed on its upper side, so that transportation or storage can shorten no dust or dirt on the later wetted with the liquid G confusetulle 6 ⁇ addition to the actual Ab ⁇ ichtfunktion in the G confuseo réelle a while.
• Fig. 4 shows in a first exemplary embodiment the complete device according to the invention in cross-section, as it is applied to the packing surface indicated by dash-dotted lines.
• the opening element 3 inserted into the opening of the cover 2 consists of a pressure plate 3A and a piercing ring 3B, which are in two parts manufactured smd and the surface of the pressure plate 3A is flush with the surface of the lid 2.
• the pressure plate 3A is now pressed, for example with a finger, into the lid 2, so that the piercing ring 3B penetrates through the pouring opening 4 into the composite material or the PE film and there, expediently along a prepared weakening line Pieces of the composite support material or the PE film are punched out. It is particularly helpful if the piercing ring is equipped with opening aids. In the exemplary embodiment shown, these are realized as a crown 7 arranged in the manner of a ring. Furthermore, stops 9 formed on the cover 2 are provided to limit the press-in movement of the opening element 3 during the opening process.
• the piercing ring 3B has clamping elements 8 on its outer surface. These serve to hold the piercing ring 3B there after being pushed into the packaging composite material, so that when the lid 2 is raised, the pressure plate 3A of the opening element 3, but not the piercing ring 3B together with the lid 2, is removed from the area of the pouring opening 4, as is the case is shown in Fig. 6.
• the pressure plate 3A and the piercing ring 3B of the opening element 3 are shown again individually in FIGS. 7 and 8.
• the opening element 3 consists of a slightly varied pressure plate 3A 'and a corresponding pressure plate 3B', which differ primarily from the first exemplary embodiment illustrated in that the pressure plate 3A 'has a circumferential web 10 in the interior of the piercing ring 3B' in order to ensure optimal guidance of the piercing ring 3B '.
• a deflection of the piercing ring 3B 1 away from the weakening line (not shown) or a recess in the composite package sealed with PE is reliably excluded, since the piercing ring 3B 'is positively guided between the two webs 10 of the pressure plate 3A'.
• the exact structure of the pressure plate 3A 'and the piercing ring 3B' can also be seen here in FIGS. 12 and 13.
