DE102020004877A1 - Packaging for silo bales with airtight seal - Google Patents

Abstract

Silage bales are usually produced by first pressing the silage, usually consisting of withered meadow grass, into bales with a baling press and then wrapping it with silage film to make it airtight. Instead of being wrapped with silage film, the proposed packaging for silo bales consists of a reusable plastic bag with an airtight seal and a valve for sucking out the air, which is transported and stored in a big pack.

Description

The present invention relates to packaging for silo bales with an airtight seal.

A recyclable packaging is, for example, in a different form from the patent EP000000995353 famous.

It is known that silage bales are produced by first pressing the silage, usually consisting of withered meadow grass, into bales when entering the field using a baling press and then wrapping it several times with plastic film (silage film), creating an air - and waterproof packaging is created. The wrapping with silo film is carried out by a combination device (bale press with wrapping device) or after the bales have been pressed by a separate bale wrapping device. Since the silo bales are wrapped several times, a larger silo bale requires around 1 kg of plastic film. This plastic film represents waste once the silo bale has been used up.

Silo bales must be sealed airtight and watertight so that silage is produced from the withered meadow grass through fermentation.

This object is achieved by the features listed in claims 1 to 6.

The mown grass is placed in a PE film bag with an airtight seal at the top and a valve that allows air to be sucked out after the grass has been filled.

In an embodiment according to claim 2 the airtight closure is achieved with a separate clamp. Such a clamp can either consist of two rectangular metal tubes screwed together with two threaded screws or two rectangular metal tubes with a hinge and opposite threaded screw.

In a further preferred embodiment according to patent claim 3 of the invention, the airtight closure of the plastic bag is achieved by a pressure or clamp closure or an airtight zipper.

In a further embodiment according to patent claims 4 to 6, the plastic bag is packed in a commercially available, reusable and open-topped Big Pak made of resilient fabric. This Big Pak has four loops at the top and four at the bottom. As a result, the actual silo bag is protected and can be better transported and turned upside down. At the bottom of the silo bag there are optional connection points where the silo bale is connected to the outer Big Pak with glue, Velcro or snaps.

The advantages achieved with the invention consist in particular in the fact that the silo bales only have to be pressed and no wrapping device has to be used for the packaging. A cost saving is possible in connection with the reusable bag. The main advantage is the avoidance of unnecessary waste, especially since the silo film is difficult to recycle.

The invention is described below in connection with the drawings. The drawing ( 1 ) shows a schematic representation of an embodiment of the silo bag. In 1 shows the silo bag being packed into a Big Pak (x). There is an airtight seal (1) at the top of the silo bag. This closure is achieved by an airtight compression or clip closure, or separate clip or wrap. There is also an airtight valve (2) on the silo bag through which the air is sucked out. At the lower end of the silo bag there are optional connection points where the silo bale is glued to the Big Pak or connected with Velcro or snap fasteners.

The drawing 2 shows two variants of closing the silo bag using a clamp made of two rectangular metal tubes with two threaded screws (variant 1) and a hinge with a threaded screw (variant 2). In addition, there are options for closing by means of an airtight zipper or zip fastener (not shown in the drawing).

The drawing 3 shows the Big Pak in which the silo bag can be placed. The Big Pak has four loops at the top and bottom.
