Problems solved by technology

However, these perforated plates are relatively difficult to clean, making it difficult to achieve a sterile environment at the sealing station
Furthermore, there is a risk of product splashed on the plate dripping from the plate onto the package which has not yet been sealed

Embodiment Construction

[0029] Hereinafter, the term (comparable or similar) sterility means that the package, after sterilization, achieves a level of sterility that is commercially defined as sterile.

[0030] exist figure 1In, a packaging machine (not shown in full) for producing filled, final packages in the form of carton bottles of the type originally described herein is shown. The packaging machine comprises a device 1 for the sterilization, filling, sealing and final folding of carton bottles, which cooperates with a device 3 for supplying the device with a clean air stream, more specifically sterile air, According to one embodiment of the invention, the device is also included in the packaging machine. For illustrative purposes, as is apparent from the figure, the device 1 is opened (side wall S partially removed) in the area of ​​interconnection with the device 3 of the invention. For the same reason, in order to be able to see the device 3 , it is opened by partially removing the side wa...

Abstract

The invention relates to a device (3) for providing a flow of cleaned air to an apparatus (1). The device comprises a bent duct (29) having a first end (31) arranged to be positioned outside the apparatus and a second end (33) arranged to be positioned inside the apparatus, and a filter (43). Air from outside of the apparatus is conveyed through the filter for cleaning, through the duct and into the apparatus, and a cross section of the duct orthogonal to a longitudinal centre axis (L) of the same varies. More particularly the cross section at the first end differs from the cross section at the second end in that the cross section at the second end (33) has more corners than the cross section at the first end (31). The device is characterized in that the duct is bent in such a way that a direction of the longitudinal centre axis (L) at the first end (31) is angled in relation to a direction of the longitudinal centre axis at the second end (32), and in that the filter is arranged upstream the bend, relative to the flow of cleaned air.

Description

technical field [0001] The present invention relates to an apparatus for supplying a flow of clean air to a device. The apparatus includes a curved conduit having a first end disposed outside the device and a second end disposed inside the device, and a filter. Air from outside the unit is cleaned by filters and conveyed into the unit by ducts. Background technique [0002] In the food industry, beverages and other products are often packaged in paper- or cardboard-based packaging. Packaging for liquid food products is often made from a packaging laminate having a paper- or cardboard-based core layer and an external liquid-tight layer of thermoplastic material at least on that side of the core layer that will form the inside face of the package . [0003] A common packaging is the so-called carton bottle. Basically, a paper bottle consists of a lower part in the form of a sleeve similar to the above-mentioned packaging laminate, and an upper part in the form of a plastic...
