Definitions

• the invention relates to a pouring element, which is fastened on a package, with a base body which has a congruent pouring opening arranged congruent with a severable opening surface of the package, after its severing, with a pivotable lid, through which the pouring opening is attached to the base body is closable, and with an opening that is not severed and extends essentially above this opening means, through which the opening area can be severed, the opening means being able to be pressed into the pack by actuating the cover via an element arranged on the cover, and wherein the support element when the opening is not separated in is held in a position substantially parallel to the opening area.
• Pouring elements of this type are used on packings for flowable substances, but particularly in the case of liquid packaging in connection with cold, cold sterile, hot and aseptic fillings.
• Such packs are often cuboid flat gable packs which are produced from a composite material having a carrier layer made of paper or cardboard, an adhesion promoter layer, a barrier layer, in particular made of aluminum, and a plastic coating on both sides.
• a known pouring element described in German Offenlegungsschrift DE 44 09 947 AI has a base body which can be glued to a package and on which a Lid is pivotally mounted. On the side of the lid assigned to the top of the pack, a cutting edge is formed which is pivoted in the direction of the pack during the first opening movement of the lid and cuts through the opening area.
• the advantage of this known pouring element lies in its simple handling.
• One of its disadvantages, however, is that the known pouring element only releases a relatively small pouring opening.
• Another significant disadvantage arises from the fact that the cutting edge, as part of the lid, is pivoted into the pack each time the pouring element is opened. This entails the risk that the contents of the package become contaminated with contaminants that accumulate on the free top of the lid.
• the opening means is designed as a plate element which is connected in an articulated manner to the edge of the pouring opening and which is arranged in the pouring opening when the opening surface is not separated and rests on the opening surface.
• the cover covers the pouring opening, so that contamination of the pouring opening, the opening element and the opening surface is reliably avoided.
• it is necessary to press the opening element into the package by means of pressure by means of a finger of one hand in such a way that it takes along the correspondingly perforated opening surface. Pressing the opening means in such a way under direct skin contact entails the risk that contaminants adhering to the skin get into the package or in the area stick to the pouring spout and contaminate the contents of the pack when pouring.
• Another pouring element is known from WO 90/14280, in which the opening means can be pressed into the package by actuating the cover via an element rigidly arranged on the cover.
• This known pouring element is disadvantageous in terms of its function and in terms of its hygiene.
• the fact that the element articulated rigidly on the lid for pressing in the opening surface during transport and storage is unprotected, in particular due to the complicated geometric configuration, so that contamination of the contents of the package during the opening process cannot be ruled out.
• contamination of the package contents cannot be ruled out.
• this known pouring element has the disadvantage that the element which is firmly articulated on the lid is deflected almost 180 ° during the opening process. This means that the pack composite part of the opening area must also be bent by 180 °. As a result, restoring forces occur which can lead to the pouring element glued to the pack being detached.
• the object of the invention is to improve a pouring element of the type mentioned at the outset and described in more detail above in such a way that hygienically perfect cutting of the opening area of the pack is possible with simple handling and construction.
• this object is achieved in that the element for actuating the opening means is designed as a support element which, after removal of a holding means, erects itself automatically into the pivoting path of the cover.
• the opening means via a support element, which erects itself automatically after the removal of the holding means. Coupling with the cover only occurs when the cover is moved into its closed position.
• neither the opening means nor the support element have to be touched, so that a hygienically perfect opening of the package is possible with a conceivably simple construction and handling.
• the opening means is arranged in the pouring opening when the opening area is not separated and is connected in an articulated manner to the base body.
• the support element can advantageously be fastened to the opening means and the holding means can be formed by the cover.
• the pouring opening is closed by the lid during storage of the unopened package. At the same time, this holds the support element in its position approximately parallel to the surface of the pack between the opening means and the cover. As soon as the lid is pivoted into its open position, the support element automatically stands up.
• the lid is then pivoted again in the direction of its closed position and thereby hits the support element protruding from the opening element, so that the opening element is carried along with the continued pivoting movement and cuts through the opening surface of the pack. After cutting, the opening element remains in its protruding into the package End position.
• the support element also protrudes into the pack.
• both are hygienically harmless because both the opening means and the support element are covered by the lid and protected from contamination during storage of the unopened package.
• An unhindered pouring out of the medium contained in the package can be ensured in that at least one abutment is formed on the support element, which automatically pivots onto the support element when the support element is inserted into the pouring hole opened by the opening means and which presses completely into the pouring hole Opening means automatically spreads apart such that its free end is supported on the inside of the package and the support element and with it the opening means is held in the position fully pressed into the package.
• obstruction of the pouring by the opening means after opening the package can also be avoided in that the opening means is equipped with a latching element, by means of which it can be latched in its fully depressed position in the package.
• the handling of a pouring element according to the invention can be simplified in a simple manner in that a stop for the support element is formed on the surface of the lid assigned to the opening means.
• This stop can be formed, for example, by a border that surrounds the edge of the lid and seals when the pouring opening is closed.
• the manufacture it is favorable if the support element is connected in one piece to the opening means.
• the support element is attached to the lid.
• the support element is carried by the cover and is arranged between the cover and the opening means or the pack when the package is unopened and the cover is closed until it is opened for the first time.
• the support element straightens up until it protrudes from the lid and is guided into the pouring opening when the lid is swung open again in the direction of its closed position.
• the opening means as explained above for the first alternative embodiment, is arranged in the pouring opening, the support element strikes the opening means in the course of this pivoting movement, so that it is moved into the pack while the closing movement continues, separating the opening area. It remains in this position while the support element is moved out of the pack when the lid is opened.
• the opening means isc 'formed at the free end of the support member. With such a pouring element; Even under unfavorable conditions it is ensured that the opening means for severing the opening surface is guided into the pouring opening via the support element during a closing movement of the lid. This applies in particular if the opening means is designed in the manner of an arrowhead. In view of the low manufacturing costs, it is also advantageous in this connection if the support element is connected in one piece to the cover. After the opening area has been severed, a disturbance of the support means during the pouring out of the material contained in the package can be avoided by the fact that the support element can be locked with the lid.
• the support element after it has been used to cut through the opening surface, can be folded into the underside of the lid assigned to the pouring opening and locked in this non-disturbing position.
• the connection between the cover and the support element can also be designed such that the support element can be detached from the cover. Both measures additionally prevent dirt from collecting on the support element and entering the pack.
• the support element should preferably be rod-shaped.
