Description

CONTAINER FOR FLUIDS USED IN PAINTING OPERATIONS

Techical Field

The subject of the invention is a multipurpose vessel that has the special form enabling the use of the same as the permanent returnable packing container for storage and transport of coatings, and which in performing house painting, decorator's and varnishing works may be used as the receptacle for paint and rack for hand tools as e.g. paint brushes, rollers and scrapers.

According to the internatinal classification, the invention belongs to the following field of technique:

• B44D-003/12 - Containers for Colour; Racks for Paint Brushes; Receptacles for Keeping the Rests of Colour,

• B05C-011/11 - Drums or other Containers for Fluids or other Fluid Material. Background Art

The modern solid or semisolid packing vessels for coatings have been mainly used as the containers for their storage and transport. These vessels have the shape of a mantle of truncated, hollow upright cone with equal wall thickness and small angle of the side inclination towards the central axis. The smaller lower basis of the cone is closed with the bottom and the larger upper open basis is closed with the cover. The bases of the container have the shape of a circle or ellipse. The volume of these containers amounts from two to twenty liters. In the practice, these containers are often used also as vessels out of which fluid coatings are laid manually on the surfaces in the way that in them the coating for laying is prepared and requisites for laying are soaking. Using these containers as vessels for house painting, decorator's and varnishing works has many shortages because formatively and functionally they are not constructed for this purpose. Excess paint is removed from rollers and brushes on the grill inserted in the container with coating. Temporary putting down rollers, brushes and scrapers during the work should be done on other places out of the containers which results in scattering the coating about and dirtying the space with scattered coating. The vessel according to the invention solves the technical problem of construction of one multipurpose product that meets the purpose of economical and permanent returnable container for storage and transport of fluid coatings, as well as the purpose of economical and permanent container and rack for manual laying fluid coatings. In addition to the packing containers for fluid coatings that are used also as containers for laying fluid coatings, there are also containers, made for a special purpose, used exclusively as vessels for preparation and manual laying of coatings. These containers of a simple pyramidal shape are used exclusively as containers for keeping and carrying the coating during laying without the possibility of putting down the hand requisites. The patent US 5341969 describes the container used for keeping and carrying the coating, as well as removing excess paint from brushes and rollers and temporary putting down the hand requisites during laying fluid coatings. The described container has the shape of a mantle of reverse hollow truncated pyramid on which inner lateral rear side the plane ribbed surface for removing excess coating from requisites for laying is made and on the former lateral side there is a small vessel for temporary putting down the requisites for laying coating. This container unites the role of container and rack for putting down the requisites during laying the fluid coatings. The exclusive purpose of the described container is preparation and manual laying fluid coatings. Because of a complex nine-angular shape of the opening the impermeable closing of the container was not solved and therefore it could not be used as the container for storage and transport of fluid coatings, nor for keeping the rest of coating for the next use. In case of pouring the fluid coating out of the container over the front edge of the opening, the coating is poured from the large vessel into the small one and then from the small vessel it runs out, which makes more difficult the discharge of the vessel. The arrangement and shape of the small vessel give to this container a complex form, which results in more expensive production of the whole container. Disclosure of the Invention The vessel according to the invention solves the technical problem of construction of attractive, simple and economic container for storage and transport of fluid coatings and the vessel for preparation and manual laying fluid coatings. In the factory, coating is packed in the container, which is upon completed filling impermeably closed with the cover and transported to the place for laying. The preparation of coating for laying is made in the way, that a part of the coating is poured from the vessel in order to dilute the rest of the coating with the diluent and binder and to decrease its level in the container. The prepared coating may be carried during laying in a closed or open container. In the course of laying, in the vessel the requisites are soaked, excess coating is removed from the requisites and the requisites may be temporary put away. Upon completed laying, the rest of the coating is impermeably closed in the container till the next use.

The container has the shape of a mantle of five-sided reverse hollow truncated pyramid with equal thickness of walls, which is on the upper larger base open and on the lower smaller base closed with the bottom. On the inner lateral surface of the rear side of the vessel, there is a plane ribbed surface for removing excess coating from the requisites for laying. In the inner front lateral angles of the container there are two compartments with slots for temporary putting down the requisites for laying the coating. The central front angle of pentagonal opening of the vessel is free and used for pouring the coating out of the vessel. The pentagonal opening of the vessel is strengthened by the bended collar entering into the groove of the cover. The connection of the collar of the vessel's opening and the groove of thecover, make the airtight disassembling assembling joint not allowing the leakage of the coating from the closed vessel.

With the container resp. vessel according to the invention, the problems of airtight closing the vessel and leakage of the coating from the vessel during the transport and laying the coating, are solved. The space for temporary putting down the requisites for layong the coating, is increased for two spaces. The simplified shape of the whole vessel and particularly of its opening, enables simplier and cost effective manufacture. This constructional and formative properties if the vessel enable its application as a permanent returnable packing container for storage and transport of coating, as well as the vessel for paint and rack for hand tools in carrying out the house painting, decorator's and varnishing works. The container according to the invention is described by the drawings 1 to 4A. Fig. 1 is the perspective view of the open vessel. Fig. 1 A is the perspective view of the cover of the vessel. Fig. 2 is the layout of the vessel. Fig. 3 is the side-view of the vessel with partial cross-section B-B from the Fig. 2. Fig. 3 A is the side-wiew of the cover with partial cross-section B-B from the Fig. 2. Fig. 4 is the front- view of the vessel. Fig. 4A is the front- view of the cover.

The container resp. vessel 1 has essentially the shape of a mantle of five-sided pyramid with the walls of equal thickness. The lower smaller base of this mantle is closed by the bottom of the vessel and the upper larger base of this mantle is oopen and ends in the plane five-sided opening with the collar bended outwards. Lateral sides of the vessel have the shapes of a trapezoid widening a bit from the bottom towards the opening of the vessel, so that their inclination towards vertical lines piercing them, is very small. The side edges of the vessel are conically rounded. The vessel is symmetrical with reference to the vertical longitudinal plane

100 of the symmetry S .

The plane opening of the vessel 1 is airtightly closed with the five-sided plane cover 2 having the shape of a five-sided opening of the vessel 1. The seat of the vessel 1 and the cover 2 is achieved through the assembling disassembling joint between the bended collar 3 of the vessel 1 and the groove 4 on the edge of the cover 2. The airtightness of the joint is ensured

105 by the seat of the surface 5 of the groove 4 to the inner surface 6 of the collar 3 in the way, that by even pressing, the cover 2 is pressed on the vessel 1, till the collar 7 in the groove 4 comes under the elastic lower edge 8 of the collar 3. The elastic joint of the collar 7 and the edge 8 ensures the permanent joint of the vessel 1 and the cover 2, resp. airtight seat between the surface 5 on the cover 2 and the surface 6 on the vessel 1. This joint enables the use of the

110 vessel as the packing container for permanent packing of the coating and temporary putting down the surplus of coating. The vessel is opened by pulling the cover 2 upwards, till loosening the elastic joint of the collar 7 and the edge 8.

In the vessels, there are factory-packed basic components of multicomponent coatings or undiluted components of single-component coatings to be diluted with water. Factory-packed

1 15 basic components of coatings should be prepared for laying by mixing with other components or diluting with water. In order to be able to prepare the coating in the vessel 1, a part of the basic component of the coating should be poured from the vessel 1 into another vessel, so that the rest of the coating in the vessel 1, could be diluted and/or other components of the coating added, so that the composition of the prepared coating would correspond to the composition

120 necessary for laying.

The coating prepared for laying is mostly manually layed on larger plane surfaces by means of rollers and on smaller plane and angular surfaces by means of brushes. Laying is performed in the way, that rollers and brushes are plunged into the coating. In order that the coating would be evenly distributed on the plunged roller or brush, it is necessary to remove the

125 excess coating and to distribute the remaining coating evenly. This is achieved by rolling the plunged roller or pulling the plunged brush on the rough or porous surface, whereby the excess of coating shall be strained and the rest of coating shall be evenly distributed on the plunged laying requisite.

In order that the vessel 1 may be used also as a vessel for paint and rack for hand tools in

130 performing house painting, decorator's and varnishing works, the basic shape of the vessel as a mantle of five-sided truncated pyramid with equal wall thickness, was changed. The first change of the basic shape refers to the rear lateral side 9 which larger central plane part 10 is pressed in the vessel 1 in the way, that it is turned around from the collar 3 of the opening towards the inside of the vessel 1 under the angle exceedidng the angle of the

135 inclination of the side 9. On the inner surface 11 of the plane part 10 the plane ribbed plane 12, used for straining and distribution of the coating on the plunged laying requisites, is made. The width of the ribbed surface is equal to or a bit larger than the height of the largest roller and its length is larger than double periphery of the outer diameter of the largest roller. The second change of the basic shape refers to two side front edges of the vessel 1. The lower

140 parts of the front side edges of the vessel 1 are formed by prismatic incursions forming two equal recesses 13 forming in the mantle of the vessel 1 two equal step-like surfaces 14. Above the recesses 13 resp. step-like surfaces 14 in the inside of the vessel 1 there are two equal L- shaped compartments 15. One end of each compartment 15 is linked to the lateral and the second to the front side of the vessel 1. In one of the arms of each compartment 15 the

145 longitudinal slit 16 is made. Each compartment together with lateral and front side to which its ends are connected and the surface 14 on which it is located, makes the inside vessl 17. Bottoms of the inside vessels 17 are approximately on the half of the height of the vessel 1. The inside vessels 17 are used for temporary putting down rollers and brushes in course of laying the coating.

150 In such a way performed changes of the basic shape of the vessel 1 enable its manufacture by technology of pressure injection out of polymer materials as one-piece product manufactured in one tool with simple kinematics.

When the vessel 1 is used as the packing container for packing and transport, almost the whole internal hollow together with internal vessels 17 is filled up with the coatmg, up to the

155 collar 3 resp. cover 2.

When the vessel 1 is used as the vessel for laying the coating and rack for hand tools in performing the house painting, decorator's and varnishing works, the inicital highest level R of the coating prepared for laying in the vessel 1 should be beneath the bottom of internal vessels 17. A part of the internal hollow of the vessel 1 beneath the bottom of internal vessels

160 17 is used as the container for coating and a part above the bottom of internal vessels 17 is used as a rack for temporary putting down hand tools for laying the coating. On the upper part of the ribbed surface 12 placed above the level R of the coating P, removing of the excess and distribution of coating by rolling the plunged roller on the upper part of the ribbed surface 12, is performed. The rollers are temporary put down in the way that with their free end they are

165 sticked over the collar 3 in the vessel 1, so that the rest of coating may strain in the vessel 1. The coating on plunged brushes is also distributed by pulling on the ribbed surface 12. Temporary putting down the brushes is made by inserting in the inside of the vessel 17. The rest of the coating that remained on the inserted brushes is strained through slits 16 into the vessel 1.

170 Carrying the vessel 1 is made in the known manner by means of arc-bended grip, which ends are pushed in the openings 18 on carriers 19, placed beneath the collar 3 in the middle of lateral sides of the container 1.

Pouring the coating from the vessel 1 through the collar 3 above the front edge 20 of the opening is performed in the way, that the vessel is held with one hand for the grip and lifted

175 above the vessel into which the coating should be poured and fmger tips of the other hand are put in the recess 21 in the bottom of the vessel 1. By inclining the vessel 1. whereby the vessel rotates round the ends of the grip, the coating is poured out from the vessel 1 and over the front edge 20 of the opening of the vessel 1. From the description of the embodyment it results that the vessel 1 with the cover 2 is the

180 practical and economical multipurpose product. It may be used as a durable, reusable packing container for packing and transport of fluid coatings, as wellas durable usable vessel for preparing and laying the coating and the rack for temporary putting down the hand tools in the course of laying the coating.
