Description

SPILLING ELEMENT THAT CAN BE CLOSED AND YET! - PACKAGING COMPOSED WITH TOP OF GABLETE PLANO, OR ^ E PROVIDED WITH THE SAME 'U') DESCRIPTION OF THE INVENTION The invention relates to a reclosable pouring element with a base member and a closure cap which at the same time serves as an opening means, wherein a flange surrounding the opening surface of the cover The pouring element is connected in a fixed manner to the composite container with flat gable upper part, and wherein the closing lid has lateral support points which are supported in corresponding recesses of the base member, and also relates to a composite container with flat gable top that is provided with such pouring element. Composite containers with a flat gable top part in the form of a parallelepiped are known in several modalities. They are mainly used in the field of packaging of liquids in relation to filled with cold materials, sterilized in cold, hot and aseptic. These containers generally can not be closed again > ~ Once they have opened. Accordingly, it has been proposed that flat gable top composite containers of the aforementioned kind contain a pouring element within the gable of the packaging which is provided with a corresponding closure cap and by which the container also opens before being used for the first time (DE 38 08 303 Al). In this regard, in the area of the paperboard layer and the outer PE layer, a circumferential separation line for weakening the gable material is provided within which a tube is pressed, connected as a unitary part of the cover closing and matching the shape of the circumferential separation line, within the packaging material to open the package. To improve the separation of the weakened separation line, the lower edge of the tube is provided for this purpose with a suitable mechanical opening means such as cutting edges, etc. Another reclosable pouring element is known from DE 44 09 947 C2 of the applicant. In order to provide in this design a secure connection between the pouring element and the flat gable top container, the pouring element which is used in this design is formed so that the rim portion of the pouring element is oriented towards the gable seams and extends towards the gable seam and approximately within the area of the flexure edge of the packing lug and is fixed between the packaging surface and the gabled seam folded on itself. Not only is this disadvantageous with respect to the use of material and expense during the injection molding of the pouring element, but, in addition, the pouring element can be arranged only on that side of the surface of the container to which it is folded the gable seam A disadvantage of this known reclosable spill element is the connection between the base member and the closure cap.
Since the closure cap is held with its lateral support tips from the top inside the base member, it can not be reliably excluded that, during the opening movement, the closure cap is levered out of its elements of safety by means of the resistance of the composite material. It is readily understood that the recesses for receiving the support tips will be deformed by several passes of the support tips when they press the closure cap inwardly and outwardly from the base member so as to impair the functional reliability during opening and closing. subsequent of the open container. Furthermore, from document DE 196 35 087 Cl, a reclosable pouring element with a closing lid and an opening element for penetrating the container wall in a prepared weakened area is known., in which the opening element as well as the lid are supported to be pivotable about a respective axis of the base member of the pouring element and are operatively connected together so that the actuation of the opening element at the same time results in the fact that the lid is opened by folding. The support points necessary to support the opening element and the lid are inserted from the side of the container into longitudinal grooves in the base member of the pouring element. In order to carry out the opening by simultaneous bending of the lid by actuating the opening element, a relatively complex connection between the lid and the opening element is required which makes the working of the pouring element more difficult. Finally, from document DE 38 08 303 A1, a reclosable pouring element is known whose lid, in a transport position, is connected to the base element by a safety ring with a pull tab. The security ring surrounds the circumference of the lid and must be removed before the initial opening of the container by means of the pull tab so that in advance, during the first stage of opening of the container, a part is obtained that is eliminated which can be discarded separately. The present invention has the aim of improving in its entirety the reclosable pouring element, known and described above, and providing a particularly secure connection between the base member and the closure cap. In addition, it is desirable to obtain an improvement in handling and a reliable opening / closing function of the flat gable container. This object is solved by a pouring element according to the preamble of claim 1, wherein the recesses in the base member are arranged on the packaging side so that the closure cap can be held in the recesses of the member. of base for receiving the support tips from the side of the container and wherein, between the base member and the closure lid, a positive locking connection is provided which is destroyed when the closure lid is operated for the first time. Although the fastening of the closure element within the base member according to DE 44 09 947 C2 is carried out from the foregoing, the solution according to the invention has the advantage of too strong a loading of the closure cap not resulting in the detachment thereof from the base member, as may sometimes be the case with the pouring element known from the prior art. In this way an undesirable "leverage" of the closure cap is reliably excluded. The positive locking connection between the base member and the lid element, which is destroyed when the closure lid is used for the first time, forms a "tamper-proof closure" for the pouring element. Such tamper proof closure makes it possible for the consumer to detect immediately in a container with flat gable top that is provided with a reclosable pouring element, if it has already been opened once or not. This is a welcome solution with regard to hygiene reasons, but also with regard to safety considerations since, in recent years, unfortunately poisoned food products have been detected more frequently. In an advantageous embodiment, the pouring element according to the invention further has a circumferential seal which can be arranged on the base member and / or on the closure cap. By means of such seal, it is ensured that the container, once opened, can be agitated, with the pouring element that is closed, to mix the contained product without the product spilling from the container. The circumferential seal may also be formed by corresponding ridges which are produced as monolithic parts of the base member and / or the closure cap. Preferably, the base member and the closing lid are immobilized by a hook, etc., in the closed position in order to avoid accidental openings. An immobilization action which is considered adequate and which preferably could work provides the consumer with an improved feeling of "safety" during use. According to a further teaching of the invention, the pouring element is closed before use for the first time, at least in the area of its product guide parts, so that they are airtight to dust. For this purpose, the base member can be provided with a pull cap, which is formed as a unitary part of the base member via connection elements that serve as a specified break point and detachably connects to the front part of the base member. the closing lid placed in the closed position. As an alternative, the base member can also be provided with a self-adhesive cover sheet that is removable before use for the first time. This reliably prevents fouling of the parts that are in contact with the product during the pour. This is especially important in the context of aseptic packaging because they are subjected to environmental influences over a long period of time as a result of their extended shelf life. In addition, this pulling step may also be constituted so as to provide a tamper-proof closure at the same time. In a further embodiment of the invention, the base member comprises at least one support that joins the area of its pouring opening. Such a support not only serves to make the pouring element stiffer but also as a stop in order to limit the pivotal movement of the closure cap at an angle of approximately 90 ° during the operation of the container. In this way, it will be evident, even for a consumer who has never used such a pouring element before, that the opening process is completed due to the resistance that results from reaching the top. The invention also relates to a flat gable top composite container wherein the composite part has at least one paper or cardboard backing layer and, on both sides, a polyethylene (PE) plastic coating with a surface of opening provided within the gable of the container which, after separation, provides a pour opening and is advantageously provided especially with a pouring element according to the invention. It is easily understood that in this context, not only such containers with gabled seams folded on themselves, are suitable for receiving the pouring element according to the invention, but that the pouring element according to the invention can be applied to all kinds of packaging for liquids.
In the following, the invention will be explained in more detail with the aid of preferred embodiments depicted in the drawings. In the drawings: Figure 1 shows a reclosable pouring element, according to the present invention, in a perspective view, applied to a container composed of flat gable top part; Figure 2 shows the pouring element of figure 1, in a plan view; Figure 3 shows the pouring element of figure 1 in a longitudinal section; Figure 4 shows the pouring element of figure 1 in a longitudinal section, in the open position; Figure 5 is a further embodiment of the pouring element according to the invention (without the closure cap inserted), in a plan view; and Figure 6 shows the pouring element of Figure 5, in a perspective representation. In figure 1, the pouring element 1, according to the invention, is illustrated in a perspective view. The pouring element 1 has a member 2 which is applied to a container P composed of flat gable upper part, which is shown only partially, and a closing lid 3 for penetrating the container wall in a weakened area prepared from the container P and for the subsequent closure of the pouring element 1. As can be seen especially in FIGS. 2 and 3, the closure cap 3 is held so as to be pivotable about an unidentified axis in the base member 2 and the pouring element 1. The holder of the closure cap 3 on the base member 2 of the pouring element 1 according to the invention is characterized in that the lateral support tips 4 can be held from the bottom, that is, from a packaging side ( rear) within the recesses 5 that are provided in the base member 2 of the pouring element 1. In this manner, an accidental "leverage" of the closure cap 3 from the base member 2 of the pouring element 1 can be reliably avoided. A support 8 provides a stop for the closure cap 3 in its open position. Figure 3 shows that the closure cap 3 is preferably provided with a circumferential seal 6 which, formed as a circumferential unitary rim, provides a reliable sealing action between the closure cap 3 and the base member 2 in the closed position . Since the reclosable pouring elements 1 of this kind are usually of a two-part construction, it is provided according to the invention that between the base member 2 and the closure cap 3 a connection is provided. positive immobilization which is destroyed before the first actuation of the closing cover 3. In the illustrated and consequently preferred embodiment, the base member 2 has a tip 7 for this purpose which, after assembly of the base member 2 and the closure cap 3, is preferably deformed by application of heat and / or connects with the closure cap 3 placed in the closed position and forms in this area a specified breaking point. In this way, the user of a flat gable lid package designed accordingly can immediately detect by means of a specified break point intact ("tamper-proof closure") that the container and therefore the product contained they have not been used improperly. In figure 4, the pouring element described according to the invention is presented in the open position in the longitudinal section.
Figure 5 shows a further embodiment of the pouring element 1 ', according to the invention. It differs from the pouring element 1 previously described in that the front part in the area of the unidentified pouring lip, a pulling lid 10 is held by means of a connecting element 9 which is formed by narrow supports, wherein the lid of pulled, after the insertion of the 3 'closing cap, it is folded over the closing lid in the closed state in order to seal in a dust-tight manner the front part of the base member 2 ', which comes into contact with the product when the pour is made. Conveniently, this pull-on lid is joined with one or more welding spots 11 in the area before the support 8 is formed and the end of the pull member 10 is formed as a tab 12, allowing easy removal of the lid 10. of pulled. It is understood that the connecting elements as well as the welding points 11 are dimensioned in a manner that reliably ensures easy removal of the pulling cap 10. Figure 6 finally shows the pouring element 1 'in its state applied to the container P'.
