Abstract

The dispenser-nozzle (1) has a base part (2) and a slit-shaped discharge or an application opening (5) which is formed by two even longitudinal edges (5a, 5b) and two transverse edges that form narrow sides of the slit and stand transverse to the longitudinal edges. The opening forms an end of a spout (4), which is continuously tapered by a bundle-sided base surface (3) of the base part to the opening, where the opening is eccentrically positioned with respect to the base surface.

Description

The present invention relates to a dispenser nozzle, a cap adapted thereto, dispensers and application packages containing this dispenser nozzle, and the use of such devices and pastes adapted for use with such devices.

Wide jet nozzles are already known. WO2005 / 011875 discloses such a nozzle provided with a blade for distributing the paste. However, the nozzle disclosed there leads to an uneven distribution of the paste. This nozzle of the prior art is thus not suitable for the direct application of, for example, spreads.

The object of the present invention was therefore to provide a broad-jet nozzle, which u.a. is suitable for applying spreads to a slice of bread in such a way that no subsequent distribution, e.g. by means of a knife, more is necessary.

This object is achieved by providing a dispenser nozzle according to claim 1. Advantageous embodiments are given in the dependent claims and the description. Further aspects of the invention can be taken from the independent claims and the description.

The invention therefore relates, in a first aspect, to a dispenser nozzle which has a slot-shaped outlet or application opening which forms the one end of a channel ("a beak") which continuously tapers from the base surface of a base part of the nozzle (inlet opening) to the outlet opening. In terms of footprint, the outlet can be be positioned centric or eccentric, with eccentric positioning is preferred. Such a dispenser nozzle allows a uniformly thin or shaped (eg wavy) layer of a viscous, spreadable material ("paste") to be applied to a substrate surface (such as bread or biscuits).

In an advantageous embodiment, an edge of the beak, resp. the outlet from the base slightly higher, e.g. by at least 0.1 mm, but usually not more than about 5mm. With an eccentric spout opening, this edge is preferably the center nearer edge. Experiments have found that these measures have a very positive effect on the coating effect.

In a further advantageous embodiment, the substrate-side edge is the peripheral edge; this is advantageous inclined with respect to the base of the outlet opening sloping, with an angle in the range of 15 ± 1 °, preferably 15 ° has been found to be well suited. The inclination of the edge can be realized by the material thickness of the beak.

The design of the narrow sides of the spout and the shape of the Ausgusschnabels is relatively uncritical. The narrow sides can be perpendicular or angled to the base, always with the proviso that the beak tapers towards the spout opening. The shape of the spout may be symmetrical or asymmetrical, preferably asymmetrical, relative to the longitudinal axis of the outlet. Furthermore, the usgussschnabel with radii or straight surfaces, preferably with radii, be designed.

Further advantageous dimensions of the dispenser nozzle are given below: For a good application thickness for spreads, an outlet opening with a diameter transverse to the longitudinal direction, ie a slot width of> 0.2 mm proven, usually from 0.2 to 12 mm, in particular from 0.5 to 1.5 mm, more preferably from about 1 mm. The area around the upper limit of about 12 mm is primarily suitable for products with thick consistency, such as spreads with meat, cheese, etc. In order for an acceptable order is possible, the outlet should be at least 5 mm above the base, preferably 20-25 mm. The extent of the outlet opening in the longitudinal direction is not critical, but in general it will be at least 20 mm, preferably 20 to 40 mm, particularly preferably 25-35 mm. The size of the opening of the beak in the base is not critical, but it should be at least 5-15 times larger (diameter transverse to the longitudinal direction of the outlet opening) than the corresponding extent of the outlet opening.

In the following, advantageous embodiments of the base part are given: A dispenser nozzle according to the invention is provided on the side of the base surface facing away from the beak with a base part which can be placed on a container and can be detachably or non-detachably connected thereto. In an advantageous embodiment, the base part has a thread or a design for bouncing. The base member may have a socket with integral fastener or, in the case of an asymmetric positioning aid or when used on e.g. a tube - a pedestal and a mounting base, e.g. a threaded socket consist.

In a further advantageous embodiment, the base part is designed so that it forms a storage space for the paste to be applied. Thus, the dispenser nozzle 1 can be equipped with a base 2, which has an adapter base 2c in addition to a threaded base 2b. The adapter base 2c forms a reservoir, which ensures that in use the entire beak 4 is filled with material to be applied, so that uniform application takes place from the application opening 5.

In a further aspect, the invention relates to a closure cap , which is adapted to the dispenser nozzle described above, and a dispenser nozzle which is closed with a Verschluskappe. In principle, such closure caps may be connected to the dispenser nozzle or be removable. While a hinged closure cap connected to the dispenser nozzle is possible, a removable closure cap is preferred. Hinged caps, which can be folded back so far that they are far enough away from the outlet to allow undisturbed order, are difficult to realize. Therefore, removable caps are currently preferred, despite the risk of losing them associated with such caps.

So that the cap easily put back on the nozzle resp. can be pressed, it is preferred that these and the base surface containing base part are designed asymmetric, so that the correct positioning of the cap is readily recognizable. Preferably, the closure cap is guided at at least two places and has on its inner side at the top an engaging into the outlet opening and this additionally closing rib.

In an alternative embodiment, the nozzle according to the invention and the closure cap are each equipped with one of the intermeshing parts of a thread, wherein a thread which requires only a minimum rotation, eg 90 °, is preferred. Positioning aids can be dispensed with in this embodiment. Instead of engaging in the outlet opening rib, for example, a sealing insert can be provided.

In an advantageous embodiment, the closure cap 10 is constructed so that the top surface 12 forms a base for the dispenser or the application packaging. This measure ensures that the filling material can flow regularly to the outlet opening and thus an easy handling is favored.

The invention further relates to a dispenser nozzle (" dispenser ") provided with a container. The container may have any shape, as long as it is suitable for the desired application. Preferably, the container is designed so that it can be easily grasped and held by hand and automatically taken by the user in the hand so that the nozzle comes in the correct position for the order. The container can, with sufficient flowability of the contents, be relatively rigid, but is preferably a flexible container, which can be additionally emptied by applying pressure.

To make dispensers more appealing, the dispenser nozzle can be provided with an adapter wall 17, e.g. creates a symmetrical, stepless connection to the tube body.

A dispenser according to the invention may contain one or more pastes, the container being filled with several pastes by means of e.g. Coextrusion is filled. In another embodiment, the container is a multi-chamber container, which is connected to an application nozzle as described above, or an application nozzle as described above is provided with partitions which form the continuation of the walls separating the chambers of the multi-chamber container and against the and preferably to the outlet opening extend.

In another aspect, the invention relates to pastes comprising a dispenser as above described in substantially homogeneous layer can be applied.
