Description

The invention relates to a resealable drain element for packaging, in particular a combined packaging for liquid food products, with a base containing a drain neck and a flange with surfaces in the form of a polyhedron for connection to the packaging body, and a mandrel of a rotating reference wheel of the packaging machine having a free end to accommodate the corresponding drain element. In addition, the invention also relates to a combination of a resealable packaging drain member and serving in the packaging manufacturing process to form a geometrical closure with a mandrel drain member of a rotating reference wheel of a packaging machine.

By re-corking "drain elements" below, we mean, as a rule, combined "uncorking and drain elements" that are located on combined packaging with drinks to open them, facilitate the pouring process and re-cork them to prevent aromatics contained in them substances, etc.

Re-corkable drain elements for packaging, in particular combination packaging for liquid food products, are known from practice in numerous ways. Combined packages should be understood as packages made of packaging material consisting of several materials interconnected by the entire surface, for example cardboard and plastic. For liquid foods, for example, drinks, soups, yogurt, etc.

A generic re-corked drain element is known from an earlier publication DE 102010048415 A1 of the same applicant. It describes a drain element according to the preamble of claim 1, which, for connection with the corresponding packaging body, is clamped onto the upper side of the mandrel of the mandrel of the heat sealing machine having a corresponding shape before the packaging body is put on the mandrel and both elements are heat-welded to each other. For clamping with a mandrel, the known drain element has several protrusions that fit into the corresponding grooves of the mandrel. To achieve a strong connection, the protrusions inside the flange of the drain element protrude relatively far, and the corresponding grooves in the mandrel are made relatively deep.

This is a disadvantage because of the relatively deep recesses in the mandrel when separating the heat-sealed drain elements from the packaging body by removing from the mandrel problems have arisen. Also, reducing the depth of the recesses did not lead to a satisfactory solution, since the reliable location of the drain element on the mandrel was not always possible. In addition, reliable cleaning of these cavities is possible only at relatively high cost. However, complete cleaning is required here, since the protrusions in the drain element come into contact inside the package with the product filled in it, and the dirt, bacteria, etc. present there. would contaminate the contents of the package.

Another publication DE 102010050502 A1 of the same applicant describes a method for manufacturing a combination package with a generic drain element using a heat seal mandrel with a package body. It shows how the drain elements are placed on the mandrel.

From JP 2009-039980 (A), it is known to connect the drainage elements of circular cross section temporarily with a geometric / frictional closure with a mandrel in the manufacture of packages, and the round landing element on the mandrel has several recesses evenly distributed around its circumference to reduce forces when connecting and separating the drain element on mandrel.

In addition, from WO 2010/106327 A1, it is known to temporarily fix a drain element on a mandrel before heat sealing with packaging. For this purpose, the mandrel has an envelope rib approximately corresponding to the inner diameter of the drain element, which interacts with several protrusions in the form of ribs enveloping the inner surface of the drain element, so that the axial donning of the drain element to the mandrel results in a geometric connection. This solution is complex because each drain element must be equipped with corresponding clamping elements.

The invention is based on the task of creating and improving the re-sealed drain element and the corresponding mandrel described above, ensuring reliable connection of the re-sealed drain element during heat sealing with the packaging body on the mandrel wheel mandrel up to the actual heat sealing and subsequent simple removal from the mandrel, as well as the possibility of good cleaning mandrels.

This problem is solved in part re-corked drain element according to the restrictive part of paragraph 1 of the claims due to the fact that the drain element contains an envelope holding element inside the base for interacting with a geometric closure with the mandrel of the packaging machine.

In accordance with this, the mandrel according to the restrictive part of paragraph 10 of the claims is made in the area of placement of the drain element in the form of a polyhedron and contains an envelope holding element for interacting with a geometric circuit with the drain element.

As regards the combination of a resealable drainage element for packaging according to the restrictive part of claim 15 of the claims and the corresponding mandrel mandrel, the problem is solved due to the fact that interacting enveloping holding elements are provided for connecting the drain element and the mandrel with a geometric closure.

Thus, in the manufacture of a combined package of a drain element and a package body, the drain element is firmly coupled to a geometrical closure with a mandrel so that it can be moved to the put on position of the package body.

Unexpectedly, it turned out that the envelope holding element also provides reliable and definite temporary holding and removal without problems with the mandrel. Due to the noticeable lengthening of the contact zone between the drain element and the mandrel, a sufficiently small depth of the retaining element, thereby also reducing the cost of cleaning the mandrel.

In another embodiment, it is provided that the envelope holding element extends in the region of the lower edge of the inner side of the flange. It is preferable both for the manufacture of the drain element in the injection mold, and for processing the mandrel.

According to another embodiment, the envelope holding element of the flange is made in the form of a protrusion. Alternatively, it is also possible that the retaining element of the flange was made in the form of a groove.

In another preferred embodiment of the drain element, the base has a square panel, the flange of which is made in the form of a truncated pyramid. This makes it possible to achieve a particularly uniform distribution of forces between the package body and the drain element.

According to another embodiment, the base under the drain neck is closed by a support wall and has an envelope weakened zone. Due to this, the opening process by means of the opening element located in the drain neck (for example, the ring to be pulled, or the cutting element, both are known per se) can occur with little effort.

However, in the framework of the invention, as an alternative, it is also possible for the base to have a concentric drain hole.

In any case, according to another embodiment, it is preferable if the base under the support wall or hole has a barrier film. Due to this, also in the area of the drain element the oxygen barrier of the package is achieved.

In other suitable embodiments, it is provided that also the envelope holding element of the mandrel is made in the form of a groove or, alternatively, in the form of a protrusion.

In another embodiment, it is provided that the mandrel in the area of the discharge element is made in the form of a truncated cone. Moreover, the named geometric shape preferably corresponds to the flange shape of the processed drain elements.

If the drain element is provided with a barrier film under the support wall of the base, it is advisable if the mandrel has a recess large enough to accommodate the barrier film. Due to this, in the process of heat sealing of the package body, sufficient protection of the barrier film from thermal or mechanical damage is provided.

In the proposed combination of a resealable drain element and a corresponding mandrel, the envelope holding elements preferably extend in the shape of a polygon, but it is also possible that they extend in the shape of a circle. Also in this case, the exact shape of the holding elements depends on the geometric design of the processed drain elements.

The invention is explained in more detail below on a preferred example of its implementation with reference to the drawings, which depict:

- FIG. 1 - re-corked drain element in perspective view from above;

- FIG. 2 - re-corked drain element from FIG. 1 in perspective view from below;

- FIG. 3 - the upper part of the mandrel of the rotating mandrel wheel to accommodate re-corked drain element in perspective in a top view;

- FIG. 4 is a resealable drain member of FIG. 1 in cross section (without cutting element);

- FIG. 5 - the mandrel of FIG. 3 in section.

In FIG. 1 shows a preferred embodiment of a drain element in perspective obliquely from above. The drain element contains a base 1 and a threaded cover 2. The latter sits on the drain neck 3 (shown only in Figs. 2 and 4). The base 1 contains an envelope flange 4 in the form of a truncated pyramid. The shape of the flange 4 corresponds mainly to the shape and, in particular, to the angle of inclination of the gable portion of the heat sealable with the drain element of the package body.

The bent surfaces of the flange 4 have ribs 5, which, on the one hand, mechanically reinforce it, and on the other hand, should provide better connection of the gable surfaces of the packaging case when heat sealing with the flange 4. Also, the legs 6 serve to improve the connection between the gable part of the packaging case and flange 4 of the drain element.

At the drain element in FIG. 1 indicating the integrity of the package, the tongue 7 connects the material 1 (not shown) made by the jumpers of material (not shown) with the threaded cover 2. At the first opening, the material jumpers are destroyed, as a result of which the consumer can easily detect whether the one equipped with this drain element has already been opened once. packaging.

In FIG. 2, the drain element is depicted in perspective perspective obliquely from below. It can be seen that in the area of the lower edge of the inner side of the flange 4 passes the envelope holding element 8. It serves for reliable connection with geometric closure with the free end of the mandrel of the mandrel wheel in the manufacturing process of the package. In addition, it is seen that the lower side of the drain neck 3 is closed by a supporting wall 9, made in one piece with the base 1.

The base 1 also has a weakened strength zone 3 extending concentrically to the drain neck 3, which noticeably facilitates piercing and cutting with a cutting element (not shown) inside the drain neck 3 due to the corresponding weakening of the material. In more detail, the implementation of the zone 10 of weakened strength is shown in section of the drain element in FIG. four.

The barrier film 11 under the base 1 in the subsequent opening zone provides sufficient safety for the filled product and its aroma.

In FIG. 3-5 shows the upper part of the mandrel 12 interacting with the drain element described above. The envelope groove 13 is clearly visible as a pair for the envelope protrusion 8 of the drain element. As already mentioned, although not shown, the proposed solution also includes a mandrel, the holding element of which is made in the form of an envelope protrusion, interacting with the drain element with a groove as the envelope of the holding element.

Finally, from FIG. 3 and 5, it also follows that a recess 14 is provided on the flattened upper side of the mandrel 12 to accommodate the barrier film 11, which protects it from damage during heat sealing.
