Description

The invention relates to a method for producing a container of glued together containers with a carrying handle, a device for producing such a container and the container of containers glued together and a carrying handle.

Glued together containers, which are provided with a carrying handle, for example, from DE 10 2011 119 964 B3 and the DE 10 2011 119 966 B3 known. In these containers, the carrying handle is glued to the container.

It is an object of the invention to propose an alternative solution for attaching the handle.

This object is achieved with a method according to claim 1, a device according to claim 6 and a container according to claim 10.

• - Bereitstellen eines Tragegriffs mit zwei Ausnehmungen,
• - Auflegen des Tragegriffs auf zwei Behälter, so dass jeweils eine Ausnehmung einen Behälter umschließt,
• - Schrumpfen der Ausnehmung bis sie am Behälter anliegt.

The inventive method for producing a container with a carrying handle, in which at least two containers are connected by a splice to a container, comprises the following steps:

• Providing a carrying handle with two recesses,
• Placing the carrying handle on two containers, so that in each case a recess encloses a container,
• - Shrinking the recess until it rests against the container.

The carrying handle according to the invention is advantageously made of a shrinkable material, for. As polyethylene (PE), polyvinyl chloride (PVC) and polyolefin (PO). The most strip-shaped carrying handle is provided with two recesses. The recesses are arranged so that they surround two usually adjacent containers after placing the handle. The recesses are usually round. Their centers are at the same distance as the centers of the top or upper ends of the container on which the carrying handle is arranged.

Put simply, the distance between the centers of the recesses is equal to the diameter of a container. The recesses have a diameter which is slightly larger than the diameter of the top or the upper end of the container. The excess of the recess with respect to the diameter is usually 1 mm to 5 mm, preferably 2 mm to 3 mm.

The width of the carrying handle is wider than the recess, at least in the region in which the recess is mounted. The carrying handle may have a taper between the recesses. The thickness of the carrying handle may be up to 2 mm, preferably 0.1 mm to 1 mm. In a central portion of the handle between the recesses is room for a print. The tensile strength of the carrying handle and the tear strength in the region of the recesses are greater than the tensile force exerted on the carrying handle when lifting and carrying the container.

According to a particularly preferred embodiment, the carrying handle is folded so that it unfolds when worn and thereby extended. The container is better to carry on a longer carrying handle. In one embodiment, a central part of the carrying handle between the two recesses is folded on itself and opens at a vertical train, which is applied by the lifting of the container. Typically, the carrying handle according to this embodiment in side view and in longitudinal section shows a Z-shaped design. In another embodiment, in particular, if a longer carrying handle is desired, the carrying handle in Z-shaped folding, an additional third recess or a multiple of the two recesses, for. B. have four or six additional recesses in originally two recesses. The additional recesses advantageously have a larger diameter than the recesses essential for the invention, so that the additional recesses do not rest on the container after shrinking and can be lifted off the tops or top ends when the container is lifted.

The container to which the carrying handle is attached consists of at least two containers, for example cans, bottles, bags or tubes.

The containers may be made of any material, e.g. As plastic, glass, metal or ceramic. Usually a container has more than two containers, for example four, six or more containers. The containers are often arranged in rows, usually two or three rows. The containers are connected by splices. Advantageously, the container of the container before attaching the carrying handle are connected to each other exclusively by splices. The splices are applied at the locations of the circumference of the containers where the containers abut each other. The splices are preferably arranged in the lower half, relative to the longitudinal axis of the containers. This allows a power-saving release of the container, which are usually detected at the top and solved by turning out of the container.

The splices are produced by adhesives or adhesives. All materials or compounds with which an adhesive bond between containers can be made are adhesives and adhesives in the context of this invention. Adhesives are preferably applied in liquid or viscous state and optionally dried, so that they form a self-adhesive adhesive point or an adhesive surface on a first container. Alternatively, plaster-like pads can be applied. If a second container is pressed against the adhesive point or the adhesive surface, an adhesive bond may arise or by entry of energy (light, heat and / or pressure) may arise a splice or adhesive bond that connects the two containers. In particular, UV-curing adhesives are preferred because curing with ultraviolet light is easy to perform. The other containers of the container are interconnected by comparable splices.

Due to the splices, the at least two containers are arranged at a fixed distance from each other. The carrying handle is deposited by means for storing the carrying handle on the two containers, that in each case a recess enclosing a container. The means for depositing may be formed as opposing grippers, which each take a frontal end of the handle and then, based on the container, are moved downwards. The means for depositing also use vacuum or electrostatic charge to fix and move the carrying handles. The means for depositing can be positioned anywhere where the containers have already taken their final orientation in the container. The means for depositing the carrying handle can thus be arranged, for example, where the containers are fixed to form the splice. But you can also immediately before packing the container z. B. on pallets or at any location between these two locations. Preference is given to arranging the means for placing the carrying handle as early as possible. It should be regarded as an advantage of the invention that parallel to the shrinkage of the handle further functions such. B. the monitoring of quality characteristics or the curing of the splices can be done so that neither the period of manufacture of the container is increased nor provide an additional route for the manufacture of the container with handle.

The means for depositing can remove the already isolated carrying handle from a magazine. Alternatively, the depositing means may remove the carrying handle from a roll and then cut or torn off, e.g. B. at a perforation, so that it is separated just before taking off. The removal and separation of strips from a roll is known per se.

The carrying handle is preferred by the means for depositing under a projection, so in an undercut on the container, typically z. As the undercut of a can edge or placed under the collar or guide ring or the closure of a bottle. The projection or the undercut is usually mounted, relative to the longitudinal axis of the container, near the top or at the upper end of the container. The recess is, as described above, each slightly larger than the undercut, the collar or the closure of the container, so that the removal of the carrying handle can be done easily and without effort.

After placing the handle on the at least two containers encloses a recess of the handle each a container. At least two containers are connected by the carrying handle at their upper ends.

In order to prevent removal or stripping of the handle from the two containers when lifting the container, the recesses are shrunk so that they rest against the containers. The shrinkage is usually due to increased temperature, in practice often by hot air blower. Due to the hot air, the carrying handle as a whole can be slightly shrunk. The resulting, usually low tensile stress acting on the container, however, does not prove to be disadvantageous, but it stabilizes the entire container, especially if the splices are mounted only in the lower half of the container. Unlike z. B. when gluing a carrying handle can be effected by applying a moderate tensile force by means of the carrying handle in containers with the carrying handle according to the invention an additional stabilization of the container. In addition, it proves to be advantageous that the carrying handle is positively secured to the container, so that the container next to the splices has a second compound, which is not based on adhesive and which contributes to the stabilization of the container.

The means for shrinking preferably each act on a container, so that there are two parallel means for shrinking, each applying heat to the entire circumference of the recess or the upper end or the top of the container. For this purpose, the means for shrinking are preferably channel-shaped or bell-shaped in order to enclose the upper side or the upper end of a container as far as possible. The means for shrinking can either be designed as movable units which stay a defined distance over the upper ends or upper sides of the containers, to ensure that the recesses fit tightly against the containers. Alternatively, the means of shrinking be designed parallel to the path of the container over a longer distance, which ensures that the recess fits snugly against the container. In this way, in both the moving and the stationary means for shrinking the production speed is not reduced and at the same time other processing steps for the completion of the container can be performed.

The inventive device for attaching a carrying handle having two recesses, to a container having at least two containers connected by a splice, is characterized in that means for depositing the carrying handle are provided with two recesses, so that each recess is a container encloses, with means for shrinking the recesses are provided to the concern of a container. The means for depositing and the means for shrinking have already been explained in detail above in connection with the description of the method according to the invention. The device according to the invention can be used without effort in an existing device for producing containers

To get integrated. It allows the production of containers with a carrying handle, wherein the splices, which were applied for the connection of the container, are additionally secured by a second, separate connection. The close to the containers recesses of the handle create a positive connection, which additionally stabilizes the container.

Advantageously, the device according to the invention comprises means for providing the carrying handle. These means for providing can be designed as storage or magazine for providing individual carrying handles. However, the means for providing can also be configured as a roll, from which successive carrying handles are unrolled and separated. The means for providing are thus designed for dispensing individual or individual carrying handles. The means for hanging cooperate with the means for providing and take the handles z. B. from the magazine or memory as explained above in connection with the description of the method.

Finally, the invention comprises a container of at least two containers, which are connected by a splice and a carrying handle. According to the invention, the carrying handle has at least two recesses which in each case rest against an undercut or a collar of a container. Alternatively, the containers may have more than two splices and the container may comprise a plurality of containers as described above. Preferably, the container of the container by splices in which, based on the longitudinal axis of the container, the lower half connected to each other.
