Description

Technical field

The utility model refers to packaging for liquid chemical products such as paints, varnishes, thinners, oils, etc., which is used in everyday life.

BACKGROUND OF THE INVENTION

It is known from US 5316169 metal container for chemical products, in particular for paint, which includes bottom, body and lid.

The bottom is circular, recessed into the volume of the container, along the main edge of which is formed a double bent outer burt, in which the wall of the body is tightly placed.

The body of the box is cylindrical, with a conical transition at the top, extending into a cylindrical throat, with an outwardly curved outer edge forming a closing rim. Embossed projections are formed on the conical transition, in the form of oval rings, one below the other, the first is located beneath the closing crown and the second is located below it, at the transition between the cylindrical part and the conical transition. On the cylindrical part of the body there are mounted grips for carrying the container. The wall of the body is joined to the bottom by a pressed outer bar.

The lid of the container is circular and has a concentric concave portion on its upper surface. At the periphery of the lid there are successively formed concentric U-shaped grooves, respectively, an inner, sealing groove, recessed in the volume of the lid, in contact with the inner surface of the cylindrical neck, and an outer groove forming a bracelet, tightly enclosing the closure. The bracelet ends with an outward concentric ring. The closure of the container is accomplished by the tight adherence of the sealing groove and the bracelet of the lid to the closing rim of the body of the container.

The closure of the container is not sufficiently tight and airtight, which results in a change and deterioration of the properties of the chemical products, especially the paint, which makes the container insufficiently reliable. Moreover, since the body of the boxes is cylindrical, it is not possible to transport them to each other before filling the boxes, which in turn creates inconvenience.

The production of this type of container is labor-intensive and inefficient due to the complex geometric shape of the container, which leads to a more expensive production.

The technical nature of the utility model

The purpose of the utility model is to create a packaging for liquid chemical products, especially for paint, that is practical, functional, convenient for transportation and use, and can ensure the preservation of the qualities of the paint during its storage.

The package for liquid chemical products is a box formed of a thin-walled sheet, consisting of a bottom, a body and a lid.

The bottom is circular, recessed inwards into the volume of the box, along the main edge of which there is a double bent pressed outer bent, formed by the curved walls of the body and the bottom of the box.

The body of the box is in the form of an inverted cone. The upper main edge of the body of the box is double bent outwards and is a closing crown. On the outer surface of the wall of the box, a conical step-shaped transition is formed at its lower end, and in the upper half there are two protruding outward rings, with a triangular cross-section, one above the other. The upper ring is locking and located just below the closing crown, and the lower ring is below it and serves to stabilize the body of the box and to strengthen its strength.

The lid of the box is circular, with a central concentric concave portion of the upper surface, around which there are three concentric grooves, forming three cotton rings, which give greater strength and stability to the lid. On the upper surface at the periphery of the lid, there are shaped U-shaped grooves through oval passages, an inner seal located inside the volume of the box, and an outer one representing a bracelet enclosing the closing ring of the body of the box. On the outer wall of the sealing chute, through a stepped transition, a contouring protrusion protruding outwards is formed, with the flap closed in the clamping ring. The outer main edge of the bracelet is bent inwards, with the inside space between the bracelet walls being filled with plastisol. Since the upper main edge of the box is closed in the plastisol when the lid is closed, the lid is then firmly adhered to the body of the box, which ensures that the lid of the box is sealed. For better secure closure of the body of the box, after placing the lid and exerting some effort on it, the locking board is located in the locking ring.

The advantages of the utility model are that the proposed box is reliable, with a secure and hermetic closure of its lid, which guarantees the quality of the paint. It is also convenient and functional, as the boxes are easily palletized when transported, entering one another.

An extremely advantageous feature is the well-designed lid, with the plastisol applied to it, which, when the box is closed, does not allow access to air in it, while the products stored in it retain their qualities.

The use of the proposed packaging for chemical products, in particular for paint, creates safety and convenience on the market and complies with the requirements for the storage of chemical products.

As shown in the accompanying drawings, the package for liquid chemical products is a box made of thin-walled sheet metal and includes a bottom 1, a body 2 and a lid 4.

The bottom 1 of the box shown in FIG. 1 is circular, along the main edge of which there is an outwardly shaped burt 5, the bottom 1 being recessed inwards into the volume of the box. The outer bar 5 is formed by simultaneously bending the wall of the body 2 together with the wall at the bottom 1, and subsequently the bar 5 is pressed. Above the beam 5, the wall of the body 2 is projected outwards, through a conical passage 6, and flows smoothly into a small conical surface. The body 2 together with the bottom 1 of the box are in the form of an inverted cone. The upper main edge of the body is doubly bent and pressed and forms a closing ring 7. In the upper half, there are two outwardly protruding outer rings, with a triangular cross-section, one above the other, on the outer circumferential surface of the body 2. ring 8, located immediately below the closing ring 7, and the lower ring at a distance below it, is a stabilizing ring 9.

The lid 4 of the box is circular, with a concentric sunken section, on which there are three concentric grooves 12 inside, and three bomb rings are formed between them. On the upper surface along the periphery of the lid 4, there are shaped U-shaped transitions shaped grooves, an inner sealing 11 disposed inwardly in the volume of the box, and an outer groove representing a bracelet 13 having an outer base edge 14 and enclosing the closing rim 7 of the body 2 of the box. On the outer wall of the sealing groove 11 there is a locking edge 10, which is projected outward by a stepped passage, which, with the lid closed, 4 is located in the locking ring 8. The outer main edge 14 of the bracelet 13 is bent inwards and the inner space between the walls of the bracelet 13 is filled with plastisol 3 to ensure leak-tightness when the box is closed.
