Description

FIELD OF THE INVENTION

The invention relates to an applicator for applying fluids such as liquid adhesives to a particular flat article and a closure for a fluid container according to the preamble of claim 1 or 11.

TECHNOLOGICAL BACKGROUND

For applying fluids such as liquid adhesives, paints, cosmetics, water o. The like. From a fluid container integrated applicators are known in the prior art in the closure of the fluid container, which allow a change in the order cross section, for example, from a punctual to a flat application of the fluid ,

However, the known applicators are disadvantageous in many respects. Thus, they sometimes have a complex and therefore expensive mechanical structure, tend to stick, have a limited longevity, are not easy and intuitive to use, have stiff actuators or can not be attractively integrated into the closure of the fluid container.

PRESENTATION OF THE INVENTION

The invention is therefore an object of the invention to provide an applicator for applying fluids such as liquid adhesives on a particular flat object and a closure for a fluid container according to the preamble of claim 1 and 11, the simple and inexpensive to produce, durable, smooth and easy are easy and intuitive to use and do not tend to stick.

This object is achieved according to the features of claims 1 and 11, respectively.

Accordingly, an applicator for applying fluids such as liquid adhesives, paints, cosmetics, water or the like to a particular sheet article such as paper or human skin, comprising a Fluidzuführkanal with a job mouth and a surface application element, which via an adjustment mechanism from a rest position in an applicator position increasing the order cross section of the applicator is provided, wherein the adjusting mechanism comprises a sliding with the surface application element slider for converting a thrust movement of the slider along a spatial axis in a pushing movement of the surface application element along another spatial axis between the rest position and the order position.

The applicator has a small application cross section in the rest position of the surface application element. Thus, a punctual order of the fluid can be made directly from the order mouth. For this purpose, the order mouth can be formed by the free end of a fluid channel. The small order cross-section can also be flat, z. B. an application surface arbitrary cross-section (eg., Round, circular, oval, rectangular, polygonal, etc.) for a flat order. For this purpose, the order mouth can be dimensioned larger and / or surrounded by a fluid application surface.

The applicator allows the change from the small job cross section to a larger job cross section by adjusting the surface application element from the rest position to the order position. Then, the fluid is applied to the object by the surface application element. The order cross section of the surface application element can be arbitrary, such as circular, oval, rectangular, hexagonal, square, etc.

To change between the job cross sections, an adjustment mechanism is provided which adjusts the surface application element from a rest position, in which the surface application element does not contribute to the fluid application, in an order position in which the fluid is applied via the surface application element. In this case, the adjusting mechanism converts a simple linear pushing movement of a slide along, in particular, the horizontal spatial axis into a forward and / or backward movement of the surface application element along, in particular, the vertical spatial axis. Such an operation is immediately apparent to the user and is therefore intuitive. In addition, the operation of the slider by pressing with the thumb in the slider longitudinal direction is possible by grasping or holding the fluid container by hand, so that a relatively high thrust force can be easily applied. The adjustment is easy even with small hands and there may be any blockages, z. As by fluid residues in the adjustment mechanism or drying or sticking to the applicator, are easily overcome, at least easier than a rotary motion, especially since slippage of the fingers is excluded in the thrust movement according to the invention.

To implement the pushing movement of the slide along any spatial axis in a pushing movement of the surface application element along any other spatial axis between the rest position and the order position, the adjusting mechanism has a bevel engagement. An element of the slider and an element of the surface application element slide in an oblique engagement past each other under relative displacement of the slider and the surface application element to each other. Such oblique engagement is mechanically simple and inexpensive to produce, durable and smooth. The degree of skew is also easily adaptable to the desired stroke of the surface application element, the desired thrust and the relative arrangement of the spatial axes. The degree of skew is preferably about 40 ° to 50 °, or shallower, e.g. B. by 30 °, when a lower actuation force is desired.

The oblique engagement may comprise a tongue and groove connection, wherein expediently the spring is arranged on the slider and engages in a groove on the surface application element (or vice versa). Such a configuration is particularly easy to manufacture and mechanically strong.

It is advantageously sufficient to design the spring as a pin and / or the groove as an obliquely placed slot. The pin can be made short with a small cross-section, whereby the mechanical stability is increased and a break is prevented even at high loads. The spring or pin can slide along an inner boundary surface of the groove or slot and in an opposite thrust direction along the opposite inner boundary surface of the groove or slot along a thrust direction, thus providing a downward or upward thrust on the surface actuator exercise.

The groove preferably has an end-side detent eye for the rest position of the surface application element and / or an end-side detent eye for the application position of the surface application element. As a result, the slider engages noticeably in its end position and even when applying the fluid can not slip out of the order position when the applicator is pressed with force on the object.

Instead of a tongue and groove connection or in addition, the oblique engagement may have an inclined shoulder on the slider or on the surface application element, which slides on a counter element such as a pin or another shoulder on the surface application element or on the slide along. As a result, an increased mechanical stability is created.

In order to prevent tilting of the surface application element during extension and / or retraction, two oblique engagements may be provided. Preferably, the oblique engagement are spaced from each other and expediently provided on both sides of the center of the surface application element. There may also be more than two oblique engagements.

The slider is preferably displaceable along a substantially horizontal spatial axis and the surface application element along a substantially vertical spatial axis. The spatial axes are thus arranged relative to each other preferably at an angle of about 90 °. But you can also form an angle of about 80 °, 70 °, 60 °, 45 °, 30 ° to each other. The angle can also be selected in the range between 80 ° and 100 °, 85 ° and 95 °, 60 ° and 90 °, 60 ° and 80 °, 45 ° and 60 °.

Appropriately, the order cross section of the surface application element in the order position surrounds the order mouth of the fluid supply channel. Thus, the fluid is supplied in particular centrally to the surface application element and can be distributed uniformly over the order cross-section. The surface application element preferably has an encircling, for example, bead-shaped embossment which delimits a recessed inner region into which fluid to be applied is introduced via the fluid supply channel.

For fixing the adjusting mechanism to a closure for a fluid container and for guiding the pushing movement of the applicator element and of the slide, a cap encompassing the slide and the surface applicator element can also be provided, which has a fastener element for fastening to the closure on the slider end and fluid container side. This is an existing only three mechanical components (slider, surface application element, cap) existing applicator on a closure, for. As a screw, with Fluidzuführkanal possibly subsequently attachable.

The fluid supply channel expediently extends in particular centrally through the slide and the surface application element.

The cap, the slide and / or the surface application element are preferably each formed in one piece from in particular plastic. A multi-part or modular design is also conceivable.

The invention further provides a closure for a fluid container, in particular for a liquid adhesive bottle, with a screw cap o. The like. And an applicator according to the invention.

Further details, features and advantages of the subject matter of the invention will become apparent from the subclaims, as well as from the following description and the accompanying figures. Individual features of the claims or the Embodiments may be combined with other features of other claims and embodiments.
