DE9013390U1 - Container with a lid - Google Patents

Description

The invention relates to a container provided with a lid for holding paint, which is fed into a spray gun for application using the so-called "air brush" technique. In the aforementioned air brush technique, the paint is applied in a fine mist using the spray gun under air pressure, particularly in model making, where the application can be carried out on scaled-down replicas of vehicles, aircraft, etc. This air brush technique is used by people such as children, young people, hobbyists, or lovers of model replicas.

With the containers of this type that were previously used, the lid had to be unscrewed in order to be able to pour the appropriate amount of paint from the container into the spray gun or its paint chamber. Unscrewing and re-screwing the lid is cumbersome and time-consuming. When handling the open container, the lid can get lost or fall off the work table. Furthermore, paint can spill out of the container.

, 1 can be spilled from the container and soil the person's clothing or the work table. The exact dosage of the amount of paint that is dispensed from the container into the spray gun is problematic. In addition, the paint containers are open for a long time, which leads to a detrimental evaporation of the solvent.

The aim of the invention is to improve the function and usability of such a container compared to the prior art.

To solve this problem, based on the generic term of claim 1 cited at the beginning, the feature arrangement according to the characterizing part of claim 1 is provided. In order to dispense paint into the spray gun, such a container is simply held with its lid end pointing downwards so that the paint enters the outlet opening. The area mentioned is then activated by pressing with the finger. This increases the internal pressure in the container and thus causes paint to exit from the outlet opening. The dosage can be so fine that only individual drops are dispensed. This is important for carrying out the air brush technique, for example if you want to nuance a color very finely or mix it with other colors. The person can have several such containers filled with paint on the table, each container containing a different color, in order to mix the right color combination in the spray gun. The lids remain on the container at all times. The

The disadvantages described in the technology are avoided.

A preferred embodiment of the invention is the subject

of claim 2. Such a section in the form of a hollow sphere-like part can be easily operated by finger pressure, whereby the person has the possibility of more or

,1 by pressing the wall of this section a little deeply, the amount of paint that comes out can be adjusted. The internal volume of this hollow sphere-like section is relatively large, whereby the wall of the hollow sphere-like section can be kept relatively thin. This means that enough paint can be dispensed even if the finger strength is not too great.

The features of claim 3 facilitate handling and, above all, the introduction of paint into the spray gun.

Claim 4 prevents evaporation of the dye solvents when not in use, with claims 5 and 6 representing advantageous embodiments of a closure according to claim 4.

Further advantages and details of the invention can be found in the following description and the associated drawing of possible embodiments according to the invention. The drawing shows:

Fig. 1: a plan view of an embodiment according to the invention,

Fig. 2: a longitudinal section along the line II-II in

Fig. 3: a further embodiment of the invention for _the design of the paint outlet opening.

A container 1, e.g. made of glass or plastic, holds the paint 14 and has an external thread 4 onto which the internal thread 3 of a lid 1 can be screwed.

.- 1 The lid 1 is provided on its top with a circumferential collar IO, in which an area is provided which can be pressed against the spring action in the direction of the arrow towards the inside of the container. If this pressure force is removed, the area returns to its original position due to the springy elasticity. According to the preferred embodiment shown in the drawing, this area consists of a part with corresponding inherent elasticity, e.g. a part made of rubber, which here is designed in the form of a section 11 of a part of a hollow sphere or a section of a similarly shaped hollow body. On the underside, the section 11 can also have bends, between which an air passage 12 is provided, which continues in an air passage 13 in the lid material, so that the air inside the section 11 reaches the inside of the container when pressed in the direction of the arrow. The section 11 is attached to the cover 1 in such a way that it has a sealing effect, e.g. by gluing, that no air can escape from it when the section 11 is compressed as described above. Furthermore, an outlet opening 15 is provided, which passes through a nozzle 5, which is filled with the material of the cap, e.g.

a plastic, is in one piece and can be locked on the top by a closure 7.

During operation, the arrangement is as shown in Fig.

2 is rotated so that the lid area is lower than the bottom of the container, so that the paint 14 at least reaches the opening 15. If the section 11 is then pressed in the direction of the arrow, this results in a reduction in the internal volume of the container, whereby part of the paint is caused to exit from the opening 15. Since the section 11 is made of an elastic material, it decreases after the pressure force is removed (see

gg arrow) returns to its original position shown in Fig. 2

, 1 form automatically. Such a resilient restoring force could also be achieved in other ways, e.g. by a spring, which is compressed when the pressure force is exerted according to the arrow and a flexible area is pressed in and, after the pressure force is removed, restores the initial position of the flexible area. Due to its structural simplicity and robustness, however, the design shown in Fig. 1 and 2 is the preferred embodiment of the invention.

The outlet opening 15 and the nozzle 5 surrounding it protrude from the lid, preferably in the longitudinal direction of the container, so that even inconveniently located paint intake areas of the spray gun can be reached.

Fig. 3 shows a preferred embodiment of the removable closure 7 of the outlet opening. It consists in a design of the nozzle 5 such that it continues into a relatively thin neck 6, which ends in a closure part 7' with a closure mandrel 8 located centrally on the inside. The passage opening 15 is closed off by this until shipping. When first used, the neck 6 is cut off along the line A-B. The cut-off part can then be used as a closure, with the mandrel 8 fitting into the mouth of the outlet opening 15 and the annular space 16 between the mandrel 8 and the closure outer ring engaging over the frontal projection 5' of the nozzle 5 with a snug fit.

3Q All features shown and/or described, as well as their combinations with one another, are essential to the invention.
