Description

The invention relates to a painter's container, preferably with an additional closure function.

From the prior art, painters' containers as buckets for transporting and mixing paints, solvents, liquid plasters or other painting needs are basically known.

In particular, plastic buckets with clip-on plastic lids are known. Particularly disadvantageous here are the high consumption of plastic material, limited impact stability and high environmental pollution during disposal. In the German utility model DE 172 9 131 U For example, a metal bucket is described which can be equipped with disposable paper inlays for mixing colors. These are removed and disposed of after use.
The disadvantage of these buckets is their comparatively high weight and the fact that they are unsuitable for transport without special precautionary measures.

The object of the invention is to show a painter's container which has a high ecological compatibility, a low dead weight, high robustness against transport loads and against loads during mixing processes as well as high tightness and resealability and can be manufactured inexpensively.

The object is achieved by the features listed in claim 1. Preferred developments emerge from the subclaims.

According to the invention, the painters 'container is designed to hold paints, solvents, liquid plasters or other painters' needs, which are referred to below as the content medium.

According to the invention, the painter's container has a base body and an inner layer. The inner layer is arranged in the base body and is preferably removable.

According to the invention, the base body has a cylinder body, a base and a cover. The volume enclosed in the base body can be designed variably. It can preferably be designed for a filling quantity of 0.375 I, 0.5 I, 0.75 I, 1 I, 2.5 I, 5 I, 7.5 I, 12.5 I and 15 I.

According to the invention, the cylinder body is formed from a wrapping paper layer material. As wrapping paper layer material, a material or composite material is understood in the following, which consists of several layers of paper or cardboard. These are preferably generated by winding the paper diagonally in a criss-cross manner. The cylinder body can also be made of several layers of paper or cardboard, which are connected by another method known from the prior art. This is particularly preferably recycling paper.

According to the invention, the bottom is made of sheet metal or cardboard. The sheet metal is made of an easily malleable material with a low weight. The base is preferably made from tinplate. The alternative of being made from sheet metal has the advantage of greater stability and less susceptibility to moisture penetration, which can be relevant, for example, when the painters' container is placed on wet surfaces. The alternative of training from cardboard, on the other hand, has the advantage of better recycling ability.

According to the invention, the base has a cylindrical edge section which is surrounded by a lower end of an inner jacket surface of the cylinder body. In the simplest design, the base is designed as a hollow cylinder closed at one axial end. The so-called sides, which are then the outer circumferential surface of this hollow cylinder, lie against the inner circumferential surface of the cylinder body when it is pushed in.

According to the invention, the cylindrical edge section and the lower end of the cylinder body are positively connected by means of clamping or riveting. Clamping or riveting in the context of the present application is also to be understood as meaning further form-fitting fixations such as crimping or the like. Alternatively, the cylindrical edge section and the lower end of the cylinder body can also be materially connected by gluing. This is particularly useful when the bottom is made of cardboard.

According to the invention, the cover is also made from sheet metal or alternatively from cardboard. The lid is preferably made of the same materials as the base.

According to the invention, the cover has a cylindrical edge section and an oversize with respect to an upper end of the inner lateral surface of the cylinder body.
The hollow-cylindrical design of the cover roughly corresponds to that of the base. In contrast to the bottom, the cylindrical edge section of the cover is oversized in relation to the inner diameter of the upper end of the cylinder body.

According to the invention, the cover is designed to be received in a closed state by an upper end of the cylinder body with the formation of an axial frictional connection.
When the cover is put on, the oversize causes a slight elastic expansion of the cylinder body at its upper end, as a result of which the opposite surface sections of the cover and cylinder body press against one another. An axial frictional connection is thus generated between the inner jacket surface and the inner layer pressed against the inner jacket surface and between the inner layer and the cylindrical edge section. By coating the cylindrical edge section with a foil membrane, the frictional connection can be reinforced and a high degree of tightness can be achieved.

The cover preferably has at least one lifting ring for better handling.

According to the invention, the inner layer is arranged in the base body and designed as a round bottom bag.
The inner layer is designed so that it can be inserted as precisely as possible into the cylinder body. It is preferably made of a flexible organic plastic.

According to the invention, the inner layer is in an adhesive bond with the inner jacket surface of the cylinder body.
The adhesive bond can in particular be produced reversibly by adhesive bonding.

The inner layer covers the inner lateral surface at its upper end and, in the closed state, is in direct pressure contact with the cylindrical edge section of the lid. When the cover is put on, the inner layer at the upper end of the cylinder body is pressed by the cylindrical edge section of the cover against the inner jacket surface and thus fixed axially non-positively and positively in the other degrees of freedom.

According to the invention, the inner layer and the cylindrical edge section form a sealing plane.
By inserting the cover into the cylinder body, the inner layer is clamped between the cylindrical edge section and the inner jacket surface and a sealing plane is formed between the cover and the inner layer along the cylindrical edge section of the cover.
For this purpose, the cylindrical edge section can be coated with a film membrane, which additionally increases the tightness of the painters' container.

The particular ecological compatibility is particularly advantageous. During production, the carbon dioxide balance is significantly more favorable than, for example, during the production of plastic containers as is customary according to the prior art. The manufacture of a 2.5 l painter's container with a lid and bottom made of tinplate produces around 1.53 kilograms of carbon dioxide, a 5 l painter's container with a lid and base made of tinplate produces around 1.75 kg of carbon dioxide and a 12.5 to 15 l painter's container with a cardboard top and bottom, around 0.8 kilograms of carbon dioxide are produced.

In addition, there is an advantage of the painter's container that a high proportion of the material input can be made from recycled material. The inner layer prevents direct contact between the content medium and the cylinder body, so that it does not have to have any particular chemical resistance to the content medium and can therefore be provided in a cost-effective and environmentally friendly manner. At the same time, a high mechanical load-bearing capacity of the cylinder body and of the base body as a whole can also be made available cost-effectively.

One advantage of the painter's container is its low weight. The total weight of the painters' container for 2.5 l of filling is 440 g, while 210 g are allotted to the cylinder body. For a filling quantity of 5 l, the total weight is 560 g, with 320 g being accounted for by the cylinder body. At 12.5 l, the painter's container weighs 800 g with a cylinder body weight of 470 g. The painters' container is therefore particularly suitable for transport including manual handling.

Another advantage of the painter's container is that it has a high level of tightness and can be repeatedly tightly closed even after opening. The painter's container can thus also have an inclined position without the content medium being able to escape. This also results in additional storage and transport options.

Another particular advantage of the painters' container according to the invention is that it can be used for mixing the content medium in commercially available paint mixing / dosing systems. Many designs of such paint mixing / dosing systems generate the stirring effect by subjecting the vessel to high and changing acceleration forces so that the content medium is set in motion. The painter's container according to the invention is so stable that it is not impaired in its structure and function by these forces.

According to an advantageous development, the painter's container has a band-shaped handle on, which is connected to the cylinder body by means of connecting bodies with two handle ends.
The band-shaped handle is preferably flexible, for example made of organic plastic, natural fiber, synthetic fiber or a flexible metal. It is preferably a biodegradable material made from plant fibers. This band is firmly connected at its ends to the cylinder body via connecting bodies.

According to an advantageous development, the connecting bodies each have a first shaped section. The first mold section is designed so that it has recesses or protruding mold elements.

According to an advantageous development, the handle has two spaced rivets, each with a second shaped section, between the two handle ends. The second mold sections are designed such that they have mold elements which can be coupled to those of the first mold sections.

According to an advantageous development, the first and the second molded section are designed to be able to be coupled in a form-fitting manner.
For this purpose, the first mold section engages with a protruding element in a recess in the second mold section or vice versa. The mold sections are coupled in a form-fitting manner. The two mold sections are preferably coupled manually. For this purpose, the respective rivet with the second shaped section is manually coupled to the first shaped section of the connecting body, preferably in the manner of a stable push button.

According to this advantageous development, in a coupled state, the handle spans the cover as a transport lock. In the coupling state, the first mold section is coupled to the second mold section.
Thus, the free area of the handle is shortened and stretches over the cover, whereby it is fixed and mechanically secured against unintentional opening.

In an open state, the handle is designed as a transport handle according to an advantageous development. In the open state, the first mold section and the second mold section are decoupled. Thus, the free area is available through the entire length of the handle between the connecting bodies and a transport handle is formed, which firstly enables comfortable carrying and secondly an opening space for the lid to open the Painter's container releases.

In a modified advantageous development, only one of the two connecting bodies has a first shaped section. Furthermore, there is only one rivet with a second shaped body. Here, too, by coupling the shaped sections, a section of the handle is used as a transport lock that can be opened and closed manually. In addition, the contents of the description for the variant with two first and second shaped bodies and rivets apply accordingly.

1 is a schematic representation of an embodiment of the painter's container in an exploded view.
The painter's container has a basic body 1 and an inner layer 2 on.
The basic body 1 consists of the cylinder body 3 , the floor 4th and the lid 5 together.
This is what the soil is for 4th made of sheet steel in the cylinder body 3 inserted so that the cylindrical edge section 6th on the inner surface 7th is applied. The design of the floor 4th corresponds in this version to a hollow cylinder closed on one side. The floor 4th is positively fixed by clipping. The clips penetrate the cylindrical edge section 6th as well as the cylinder body 3 in the area adjacent to the cylindrical edge section. Then the inner layer 2 through the upper opening of the cylinder body 3 used in which the inner layer 2 a reversible adhesive bond with the inner surface 7th forms. This is what the inner layer 2 an adhesive coating on its side facing the base body. The cylindrical edge section 6th of the lid 5 is slightly conical and with an oversize to the inner diameter of the cylinder body 3 executed.
When inserting the cylindrical edge section presses 6th of the lid 5 the inner layer 2 to the inner surface 7th and generates a frictional connection in the axial direction along the main longitudinal axis of the base body. In addition, a sealing plane is formed between the cylindrical edge section 6th and the inner layer 2 which prevents leakage or evaporation of the content medium.

On the cylinder body 3 are two connecting bodies 9 each with a first mold section 10 arranged. The ends of the handle 8th are by means of the connecting body 9 with the cylinder body 3 firmly connected.
The flexibly designed handle 8th This version also has two rivets 11 each with a second mold section 12th on.

The respective first mold section 10 is formed, the respective second mold section 2 record.
The second mold sections are used for the coupling state 12th in the first mold sections 10 used. This becomes the handle 8th with his between the rivets 11 lying section over the lid 5 tensioned and thus prevents unintentional opening of the lid 5 .
In the open state, the mold sections 10 , 12th decoupled from each other and the handle 8th can be used again in its original function as a transport handle. In the opening state, the opening movement path is through the handle 8th no longer locked and the lid 5 can be opened.

In 2 and 3 the function of the transport lock according to a modified embodiment is shown schematically. Furthermore, the painter's container is assembled in these figures and shown in a partial section. The basic structure corresponds to that of the exemplary embodiment according to 1 . 2 shows the coupling state in which the handle 8th is effective as a transport lock. 3 shows the open state in which access to the lid 5 free is.

The handle 8th has only one rivet in this version 11 with a second mold section 12th on. Here, too, only one of the two connecting bodies has 9 a first mold section 11 .
The coupling state or the opening state is established as in 1 described. By coupling the second mold section 11 on the rivet 11 with the first mold section 10 on the connecting body 9 becomes the free area of the handle 8th to the length between the connecting body 9 which does not have a first mold section and the rivet 11 shortened. This free area now spans the lid 5 and thus acts as a transport lock.

In the 2 and 3 is also the position and design of the two cylindrical side sections 6th shown in more detail. The lid 5 with an oversize to the inside diameter of the cylinder body 3 is slightly conical here. In the closed state, the cylindrical side section presses 6th of the lid 5 the inner layer 2 to the inner surface 7th and thus creates a tight and axially non-positive connection.
