Manual unrolling device

Abstract

A manual unrolling device for unrolling and tearing off a rolled up foil or paper web includes (a) a housing in which a winding body can be placed and having at least one web outlet opening; (b) at least one lid cover connected to the housing via a hinge; and at least one cutting element for separating a web section. The cutting element is arranged on a lower side of the lid cover that is directed toward the web outlet opening. A redirecting bar, and at least two pull-off bars across which the web is guided, are arranged parallel to each other at the web outlet opening. Upper edges of at least one pull-off bar are provided with a friction-enhancing coating, and the pull-off bars have a gap between them into which the cutting element dips when the lid cover is closed.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a device for unrolling and tearing off a rolled up foil or paper web, with a housing in which the winding body can be placed and which exhibits at least one foil outlet opening, and with at least one lid cover connected to the housing via a hinge and with at least one cutting element for separating a foil section.[0002]Such a manual unrolling device is known from DE 203 15 295 U1. This device can indeed be used to tear off foil pieces creating a straight separation line. However, the separation is carried out such that the foil is drawn against a toothed bar, which requires a relatively great force. In addition, to withdraw the next section of the foil, the lid cover needs to be opened in order to grasp the foil again at its end and pull it out of the housing.SUMMARY OF THE INVENTION[0003]It is, therefore, the objective of the invention to optimize a manual unrolling device with regard to easier operation.[0004]This o...

Benefits of technology

[0012]The user can grab the cut section and tear it off at the remaining bridge connection. To this end, he pulls at the same time additional portions of the foil web partially out of the manual unrolling device. The tip protruding in this manner from the manual unrolling device is used to easily grip the foil web upon the next use.

[0016]Preferably, this side flap is connected to the housing or the lid cover via a film hinge. In particular, the film hinge is designed as a so-called butterfly hinge, such as is known, for example, from one-piece lid connections on packages for body care products. This design allows for defined closing and opening positions. Random unintentional opening of the side flaps is prevented because force must be used to overcome a dead center between these positions. According to one preferred embodiment, it is provided that when closing the lid cover at least one spring element, which is designed in particular as a leaf spring, is deflected. The spring element should preferably be arranged centrally in the area of the redirecting and pull-off edges. This has the following two effects:

[0018]The spring, which not only pushes the lid cover up but in addition also pushes from underneath against the web located above, lifts it up from the pull-off bars. In this manner, the user can easily pull the web out to the desired length without having to hold the lid cover and having to keep the foil from the friction-reduced coated pull-off bars.

Problems solved by technology

However, the separation is carried out such that the foil is drawn against a toothed bar, which requires a relatively great force.
