Hand dispenser for flexible roll material

The invention relates to a handling device for flexible roll material made of a wide variety of materials. For the roll material flow, from the supply roll to the point of use, several adhesion and anti-reverse devices are provided, as well as a holding area with handle recesses on both sides for easier roll material removal. The access recesses provided reduce the adhesive effect and only exist between the handle recesses, thus allowing problem-free initial handling for right- and left-handed people.

Furthermore, a roll material cutting mechanism with automatic opening mechanism is provided, which enables the cutting arm, which is automatically released in the cutting readiness, to be held in the cutting readiness without locking by means of the spring means of the opening mechanism.

It is generally known and customary that when using flexible roll material for paper, plastic and/or cable connections, unwinding devices and unwinding containers are used, which essentially consist of an unwinding holder and a separating device and have found widespread use in a wide variety of designs.

Based on this, the invention aims to further develop such devices in order to improve their handling during and after application and reuse.

This object is achieved according to the invention in that a handling device is proposed in which, in addition to the previously known roll material guides and separating devices, the user is provided with a handling device through an advantageous further development of the invention that can be used without problems and without danger in every application, in particular in that in addition to the specially arranged unwinding guide and adhesive surface protection against external dirt, contamination of the adhesive surface in the holding device, material sticking is also avoided and injuries caused by the separating teeth of the automatically disengaging separating arm cannot occur.

The lock-secure return of the separating arm is also problem-free and safe. In contrast to most roll containers on the market, this version according to the invention can be stored in briefcases, tool bags, school and college folders, writing cases, work coats, suit jackets, in women's handbags (e.g. our small version) and in men's trouser pockets, ready to hand and use at any time.

The container construction, the different, pleasing design, the practical and ready and safe application in any situation, guarantees long-lasting storage and use, in contrast to environmentally harmful disposable mass production, which is on the market with its technical simplicity and equally simple form design.

In the attached drawings, only a few embodiments of the handling device according to the invention can be shown and described as follows:

The handling device according to the invention consists of the base plate (1) and the cover plate (1a). The separating boom (2) is pivotally mounted via a provided centering pin (3) and is pivoted by means of a fitted spring means (8c), after the detent release (4), in the direction of the arranged display limit (7) and is held by spring force in a non-latching and safe manner.

According to Fig. 6, the separating boom ( 2 ) is secured against unintentional release of the locking button ( 4 ) by means of a locking button ( 4 ) in conjunction with the locking catch ( 6 ) and by an additional locking button safety device ( 5 ).

In the middle area of the base plate (1), a central spiral with movable spiral arms (10) is arranged to hold the roll material (13), which is formed in the middle into a bushing (11) to hold the centering and locking pin (12). The cover plate (1a) is stabilized on the base plate (1) by further bushings and pins (3 + 3a).

The central spiral (10) is designed to accommodate different roll inner diameters, and therefore when empty - after the roll has been removed - is larger than the roll inner diameter to be used due to its spring-like expansion. To ensure that the different diameters can be adjusted straight away without much experimentation, the movable spiral wings are rounded inwards at their outer ends (Fig. 5A). Due to this arrangement, when the roll is inserted, the middle area of the spiral wings is first subjected to pressure and the larger end areas of the central spiral are automatically pulled inwards by the pressure exerted.

To use the roll material (13), the roll material is guided from the beginning of the roll over the adhesive supports (14) to the laid-out cutting boom and lightly pressed onto the adhesive and holding tongue (16) located on the inside in order to then cut it to the required length using the cutting teeth (9) provided.

When the closure is returned to the separating arm (2), the inserted roller belt (13) is additionally held in place in the rotation area of the separating arm (16) over the adhesive supports (14) in order to avoid any possible container movements and vibrations, especially in the case of weakly adhering adhesive surfaces.

Another option for preventing the belt from running back is to use spiral booms, which exert more or less pressure on the inner pipe section depending on the inner pipe diameter.

To use the handling device according to the invention, the locking button safety device (5) is returned, then the locking catch (6) is released by lightly pressing the locking button (4). The separating arm thus released is snapped by the clamped spring means (8c) over the centering pin (3) in the direction of the display limit (7) and is held there securely for use by spring tension.

The user is now able to easily pick up the adhesive tape protruding from the adhesive and holding tongue (18) on both sides via the access recesses (17) arranged on both sides of the separating arm, pull it out to the desired length and separate it via the separating teeth ( 9) of the separating arm (2).

After use, the separating arm ( 2 ) is returned to its original position and secured by the locking catch ( 6 ).

To further secure the device during storage, the locking catch ( 4 ) is additionally protected with the catch lock ( 5 ) against unintentional pressure release of the locking catch ( 6 ).

Claims (8)

1. The technical development of a hand-held unwinder for flexible roll material, characterized in that a roll material separating device known per se now swings into readiness for use via a released safety catch in action with a spring means to be arranged and is held securely in place by the spring pressure of the model-dependent spring means in order to be able to separate the required lengths of tape via the separating arm ( 2 ). 2. Device according to claim 1, characterized in that the fuses (5+6) of the separating boom ( 2 ) are to be selected for functional reliability in the different housing shapes and, if necessary, are to be arranged in different functions. 3.
