"Closure for glue container"

The invention relates to a closure for adhesive containers, in particular tubes for solvent adhesive, which consists of the container neck with the removal opening of a closure cap and a spreading element made of porous material consists.

Closures of this type are known. They usually have a sponge-like distribution body, which with the Container neck is firmly connected. The product to be applied is first pressed out of the tube into the distributor body, absorbed by this and finally again during contact with the flat object to be coated submitted. The use of these known closures is for the application of glue, especially solvent glue, not possible in practice, at least not satisfactorily. The reason for this lies in the fact that Every adhesive naturally tends to become encrusted and, after a short time, the distribution body soaked with it its flexibility and thus loses its suitability as a spreading organ. The user is therefore then free to use up the entire contents of the tube forced to remove the spongy distribution body and apply the adhesive with another instrument, In the case of solvent-based adhesive, advantage bodies made of rubber, felt or the like would also be affected by the action of the solvent become unusable in a short time. rubber

is known to be destroyed by the influence of solvents, while felt tends to soak up the adhesive, which leads to encrustation of the spotting organ. In addition, it is This type of closure is not possible without cumbersome manipulation, if necessary the adhesive can also be applied point-wise. or to be applied in lines.

This is where the invention, which was based on the object, for the application of adhesive, in particular solvent adhesive, the container closures known per se with sponge ' to improve like distribution bodies so that on the one hand either a flat application and a point or linear application is possible. On the other hand, it must be ensured here that the sponge-like distribution body does not becomes unusable due to encrustation.

As a solution to this problem, a closure for adhesive containers, in particular tubes for solvent-based adhesive, is proposed, which consists of the injection-point-like shaped and Container neck made of polyethylene with a removal opening, a spreader element made of porous foam which is attached to a holder that can be screwed onto the container neck and is preferably made of plastic, and a cap. The closure according to the invention is characterized in that the one surrounding the container neck is made of Polyethylene or neoprene foam existing spreader when screwed on the container neck only to one small part protrudes and that it is on the holder by molded on this and through the container neck outwards into the Aufstreichorgan is fixed into bendable claws.

Due to the essentially two-part design of the closure according to the invention, it is possible to have both a flat as well as a linear adhesive application. in the

In the former case, only the closure cap needs to be removed, which then causes the spreading element, which the container neck only a small part towers above, is exposed. The glue squeezed out of the mouth of the neck of the container then occurs through the opening in the spreader on the object to be coated, where it is now by means of the spreader can be distributed over a large area.

The size of the opening of the spreader corresponds to the part of the holder that encompasses the container neck, which in turn molded claws that can be bent outward through the container neck into the spreading element.

So-called closed-cell material is used as the material for the spreading organ Polyethylene or neoprene foam in question. This Material is particularly suitable because it is practically impossible to absorb and thus become encrusted and unusable tends to occur due to the solvent-based adhesive.

The closure cap, like the spreader holder, is preferably made of plastic. If, on the other hand, a point or linear application of adhesive is desired, then unscrew the spreader holder together with the sealing cap. As a result, the removal opening, which is shaped like an injection tip, is then created completely exposed for immediate use.

It is useful that the holder with a cylindrical collar is surrounded, which, like the diameter of the cylindrical closure cap, is the same as the tube diameter Has outer diameter. With this configuration, easier handling of the closure is achieved by, for example the holder grasped with one hand and then the cap can be unscrewed with the other hand. Possibly the bracket would only have to be grasped and unscrewed if point-

or linear adhesive application should take place. The cap then remains on the spreader holder.

The closure cap has a coaxial approach that is screwed on Cap seals the container mouth and thus prevents crust formation. The cap is also shaped such that together with the cylindrical collar of the holder, it surrounds the spreading element on all sides.

The advantages of the container closure according to the invention are on the one hand, as explained, the possibility of, in particular, solvent-based Adhesive can be applied either flat or in dots or lines without getting the hands dirty, in the former case also the annoying, so-called thread spinning of the adhesive is greatly reduced, so that this annoying circumstance no longer appears disturbing in practice. More important, however, is the advantage that additional and therefore easy-to-lose application instruments, such as tooth combs and the like, can be omitted, a circumstance which is particularly important for handicraft purposes. Apart from that, it would also be made of tissue paper or similar material existing objects are easily damaged when using hard string instruments.

The closure according to the invention is shown by way of example in the following figures.

Figure 3 tube mouth without closure (ready for point or Line order).

The tube 1 (see FIG. 1) has the neck 2 with thread 3, which is surrounded by the holder 4 with the spreading element 5 is. The holder 4 in turn has a surrounding cylindrical collar 6 which, like the closure cap has an outer diameter equal to the diameter of the tube 1. This enables easy handling of the closure parts achieved. The Aufstreichorgan 5 consists of closed-cell non-absorbent foam, preferably made of polyethylene or neoprene foam.

The one-piece closure cap 7 has the coaxial extension 8, which seals the tube mouth. The cap 7 surrounds together with the collar 6 of the holder 4, the spreading element 5 on all sides.

After unscrewing the cap 7, the tube 1 is available for a flat application of adhesive. The glue then comes out the tube mouth through the opening 9 of the spreader 5, to be distributed with its end face 10 on the object to be provided with adhesive. If, on the other hand, the bracket is unscrewed, the tube neck 2, which is shaped like an injection tip, is exposed and allows a point or line shape Glue application.

To fix the Aufstreichorgan 5 on the holder 4 are on the hub-like projection 12 of the holder 4, which the container neck 2 includes, claws 11 formed. The claws 11 are

bent through the container neck 2 outwards into the spreading organ 5 and thereby prevent the organ from slipping off 5 from projection 12.
