UA10569U - Container for food products, tempered with liquid, with a lid of a flexible material - Google Patents

Abstract

A container for food products tempered by liquid contains a lid of a flexible sheet material and a hollow body with the bottom. The body is formed by two layers of the sheet material, connected between each other forming a hollow truncated cone, at least the internal of which is made of a material on the basis of cellulose, preferably of dressed paper. The height of evolvement of the internal layer exceeds the height of evolvement of the outer one at least for a sum of the value of the length of an arch of the cross-section of a shoulder, formed by bending the internal layer in the upper part of the body outside lapped onto the outer layer, and the values of an internal bend of the lower part of the internal layer lapped onto a bend to the lower part of the body, made along the perimeter, forming a tight interlock joint of the bottom and the body. The junction of the joint of the internal layer of the sheet material and the junction of the joint of the outer layer of the sheet material are shifted one relative the other along the length of the circumference of the body no less than for a 1/15 of the length of the perimeter of upper part thereof. A ratio of the upper and lower diameters of the hollow body is (139±0,5):(103,4±0,5) correspondingly, and a truncated cone of the body is made at angle of (7,95±0,5)°.

Known designs of disposable containers do not have sufficient rigidity and reliability in operation when using them as a container for cooking liquid hot foods, for example, soups, and, in addition, do not provide sufficient protection for the consumer from burns from the bottom or walls of the container.

The task of this technical solution is to increase the rigidity and reliability of operation when using a container for cooking liquid hot food products, for example, soups, while ensuring consumer protection from burns from the bottom or walls of the container. c This is achieved by a container for liquid-sealed food products with a lid made of flexible sheet material, including a hollow body with a bottom formed by two layers of sheet material interconnected to form a hollow truncated cone, at least the inner one of which is made of material on based on cellulose, preferably treated paper, while the height of the sweep of the inner layer by 75 exceeds the height of the sweep of the outer, at least by the sum of the length of the arc of the cross section of the shoulder, formed by bending outwards of the inner layer in the upper part of the body against the outer layer, (ав) and the value of the inner bend of the lower part of the inner layer against the bend made along the perimeter of the bottom to the lower part of the case, which forms a hermetic lock connection of the bottom and the case, and the joint of the joint of the inner layer of sheet material and the joint of the joint of the outer layer of sheet material (Ge ) 50 shifted relative to each other along the length of approx the difference of the body is not less than 1/15 of the length of the perimeter of its upper part, in which the ratio of the upper and lower diameters of the hollow body is (139--0.5):(103.4--0.5), respectively, and the truncated cone of the body made at an angle (7.95--0.5)2.

In Fig. the general view-sectional view of a container for liquid-sealed food products with vv / Lid made of flexible sheet material is shown.

The container for liquid-sealed food products includes a hollow body 1 with a bottom 2. The body 1 is formed by two layers connected to each other to form a hollow truncated cone, inner C and outer 4 layers of sheet material, at least the inner C of which is made of cellulose-based material , mostly decorated paper. At the same time, the height of the sweep (sheet of the blank) of the inner C layer exceeds the height of the sweep of the outer 4, at least by the sum of the length of the arc of the cross section of the shoulder 5, formed by the outward bending of the inner C layer in the upper part of the body 1 towards the outer 4 layer, and the value of the inner the bend of the lower part of the inner layer 4 in the direction of the bend 6 made along the perimeter of the bottom 2 to the lower part of the case, forming a hermetic lock connection 7 of the bottom 2 and the case 1. Joint 8 of the joint of the inner Z layer of sheet material (joint line from the inside) and joint 9 of the connection of the outer layer of the sheet material (joint line from the outside) are offset relative to each other by b5 length of the circumference of the body 1 not less than 1/15 of the length of the perimeter of its upper part (this ensures the reliability and tightness of the connection). Cover 10 of flexible sheet material has a tab for its removal.

The hermetic lock connection of the bends b of the bottom 2 and the body 1 is made at a height that exceeds the diameter of the cross section of the shoulder 5 by no less than three times, which ensures the necessary ratio of stiffnesses of the upper and lower contours of the container when hot liquid is placed in it, and also excludes the contact of the hot bottom with the base on which the body 1 is installed. This is also facilitated by the fact that the lock joint (in the form of a fold) is pressed with the formation of embossing (corrugations) on the inner perimeter, preferably in two levels along the height of the lock joint, which increases the tightness and rigidity of the connection. At the same time, the truncated cone of the housing 1 is made at an angle of 11, equal to (7.95--0.5)2. The ratio of the upper (a 4) 7/0 diameter 12 of body 1 and the lower (d") diameter 13 of body 1 is (139:0.5): (103.4 0.5), respectively.

During the tests, it was established that the execution of the truncated cone of the housing at the specified angle and the above-mentioned ratio of diameters ensure an increase in the rigidity of the upper and lower contours of the container by an average of (5-9)95, as well as a decrease in the pushing of the housing, especially in its middle, in the places of capture by the consumer's hand at the moment when the container is filled with hot liquid.
