Abstract

The lid (10) has a catch by which the lid is fixed into the top part (14) of the canister. The lid has a closure segment (32) on an inner edge of the lid-opening and forms a water-tight seal at least in part of it. A pourer element adjoins the seal-segment which covers more than a third of the periphery of the inner edge of the lid opening.

Description

The invention relates to an attachment for a fluid medium Can.

In such a, a fluid medium, such as paint or similar fluids Media-containing cans with a removable lid are due the shape of the cans, which is due to their stackability, the Problem that pouring out the fluid medium always leads to the fact that this the can runs over a can jacket and contaminates it.

The invention is therefore based on the object of creating an essay with which a pouring of the fluid medium out of the can without contamination the same is possible.

This invention is characterized by an essay with the features of claim 1 solved.

The advantage of this solution is that it is fluid-tight Completion of the end segment at the inner edge of the lid opening and that pouring element connected to the end segment the possibility was created, the soiling of the retaining ring of the can pour out fluid medium, the pouring element also being a has drip-free detachment of the fluid medium causing drip edge, which prevents paint from running out after pouring is complete.

With regard to the formation of the final segment, the most varied Variants conceivable.

For example, it would be sufficient to design the closing segment that it is over more than a third of the circumference of the inner edge of the lid opening bears against this fluid-tight, since already pouring out the fluid medium would be possible, but then be careful must be that the fluid medium only when pouring over the end segment flows.

It is even more advantageous if the end segment is at least approximately half of the circumference of the inner edge of the lid opening on this is fluid-tight.

A particularly favorable solution provides that the end segment along the the entire inner edge of the lid opening is fluid-tight, since this can create the possibility of any unwanted leakage to prevent the fluid medium next to the end segment.

With regard to the fluid-tight closure of the closure segment on the whole No details have yet been given on the inner edge of the lid opening made. Such a fluid-tight seal can be used, for example sufficiently high elasticity of the plastic material of the end segment to reach.

However, the inner ring of the lid opening varies depending on the type Cans, it is particularly advantageous if the end segment is conical in Has wall surfaces running towards the inside of the can.

The cone angle is preferably so small that the end segment self-locking fluid-tight on the entire inner edge of the lid opening is finally fixable.

A particularly favorable angle between a central axis of the can and one Wall area of the end segment is less than 7 °.

With regard to the design of the pouring element, the most varied Solutions conceivable.

It is preferably provided that the pouring element is a fluid Has medium-leading wall, which ends at a drip edge. The the fluid medium performing wall can be in the same way as that Termination segment only over a certain area along the Extend circumference of the lid opening or in the same way as that Wrap the end segment around the lid opening.

Preferably, the wall of the pouring element guiding the fluid medium can parallel to the wall of the end segment, especially in continuation the same, run, and in particular parallel to the central axis extend the can or conical to the central axis of the can expand away from the closing segment.

It is particularly favorable if the wall of the pouring element contains the fluid When the can is standing, the medium is designed to lead back into the interior of the can is, so that the fluid medium always has the tendency in the standing can To run back inside the can and not in the area of the wall of the pouring element to stop.

The pouring element preferably extends in relation to the central axis the can over an angular range of at least 120 ° around the central axis the can, even better by an angular range of at least 180 ° around the Central axis of the can.

In all cases is the angular range over which the pouring element is located extends in a first approximation regardless of the angular range which the closing segment extends.

The handling of the can when pouring is particularly easy facilitate that the pouring element extends over the largest possible angular range, and especially if possible over the same angular range as that Closing element extends.

In order not only to pour out with the attachment according to the invention facilitate, but also the removal of the fluid medium by means of a Brush and the stripping of the brush, it is preferably provided that the Attachment opens an access opening for the inside of the can, its size corresponds approximately to the size of the lid opening of the can, that is is preferably only reduced by the wall thickness of the stripping element.

It is also preferably provided that the attachment with a scraper for the fluid medium is provided.

The scraper can basically through a lower edge of the end segment be educated.

A particularly expedient separate scraper makes it particularly easy Wipe off excess fluid medium with a brush.

It is particularly advantageous if the scraper extends across the Access opening extends.

The scraper could extend in the middle over the access opening. However, this would make access to the inside of the can more difficult.

For this reason, it is preferably provided that the stripper Access opening divided into two parts, one larger than that other.

It is particularly favorable if one part is at least three times the size of the other part, in order for the brush to have the largest possible access opening to get for the inside of the can.

In order to make the can, once provided with an attachment, as simple as possible To be able to store, it is preferably provided that the essay by a lid can be closed.

Such a lid could be put on in many different ways. For example, can be placed so that he the access opening in the area of Closing element closes.

A particularly simple solution, however, provides that the lid Pouring element closes, and preferably on the drip edge of the Pouring element can be placed sealingly.

A particularly inexpensive embodiment of the invention Essay provides that this is designed as a one-piece part.

The attachment can basically be made from a variety of materials his.

An inexpensive solution provides that the attachment made of plastic is made.

The plastic is preferably one on which the fluid medium, for example color, does not adhere permanently and therefore, for example in dried state, is easily removable.
