Description

Scope - social sphere, life, household, education and services, catering.

Known serving bowl having a cavity for garbage (patent WO 99/01059 from 01/14/1999, class A47C 23/08), consisting of the upper part, with a spacious place for nuts, berries, wrapped in wrappers of little things, etc. ., and the lower part, which is a garbage container).

The disadvantages of this device are violations of hygiene requirements - both food and garbage, as well as its significant size, are placed in the same design. Desktop items for garbage collection should not be so large, they should not stand out, dominate the table. Thus, the rule of anthropometric compatibility is violated.

Also known is a desktop trash can (US patent 3,984,941 dated 10/10/1976, class A47G 19/30), which is a combined flower vase and a waste container. The disadvantages of the known device are inconvenience in operation due to its non-ergonomic nature, significant size and weight.

The closest device of the same purpose to the claimed utility model in terms of all the essential features is a garbage container (GB patent 2242349 dated 02.10.1991), which is the base container into which a disposable plastic cup is inserted, which is replaced as it is filled up with garbage. The disadvantages of this container are the requirement for additional maintenance - washing, care, purchase of spare liners, which negatively affects its cost and ease of use.

The essence of the utility model is the creation of a disposable desktop simple form with a variable volume for the collection of small garbage in the home, in the social sphere.

Structurally, the container is a container with corrugated walls and a bottom. Corrugated walls with corrugation waves are perpendicular to the vertical axis of the container. The bottom may be flat or concave inward.

On the horizontal plane, the section of the structure has the form of different polygons: a triangle, a quadrangle, a pentagon, a hexagon and then up to a round shape (bellows).

Figure 1 shows a General view of the utility model in the form of a quadrangular 4-sided shape with corners (in all figures, for simplicity, the bends of the shape from the inside of the structures are not shown).

Figure 2 shows a General view of the hexagonal shape of the utility model with angles.

Figure 3 shows the shape of a utility model with a circular horizontal cross-section, similar to a flat-bottom bellows. The shape of the utility model with a circular cross section can be made with both acute-angled corrugations and wave-shaped corrugations.

The horizontal cross section of the device may be of another shape, for example, a rhombus, a star and other, more complex shapes than those shown in Fig.1-3 or Fig.5-9. In particular, the horizontal section may be non-axisymmetric shapes, shapes with section boundaries representing straight and curved sections, including concave sections, as shown in Fig. 14.

Effectively produce scalloped containers with a lid, as shown in FIG. 13. In this case, the specified cover is a continuation of the pattern shown in Fig.4. The container can be made with a lid as a separate element, including a removable one. In the case where the upper part ends with a hole, from the point of view of ergonomics, it is advisable to make a hole in a shape that repeats the horizontal shape of the main section of the utility model, but can be made round or other shape. The container opening can be of a more complex shape - from rectangular and ellipsoidal to round and star-shaped, moon-shaped.

A utility model can be implemented in several ways. Figure 4 shows one of the schemes for assembling different-angled shapes of a utility model with corners from a rectangular sheet of material used. On figa - the width of the half-hemisphere (half-wave), N is the number of half-hemispheres (half-waves), corrugated structure. The height of the maximum open structure will be A * N. B is the width of the face of the structure, M is the number of faces of the corrugated structure: for the triangular shape of the structure M = 3, for the quadrangular shape M = 4, for the pentahedron M = 5, for the hexagon M = 6. In the diagram, the lines show the fold points of a flat workpiece. If we count from above, then each odd line is an internal inflection of the corrugation, the even line is the external (curved outward). Inclined bends with an angle α are always internal bends, but the segment of the internal horizontal bend between the inclined bends is external. The value of the angle α changes in such a way that for a rectangular structure α is about 45 degrees, and with an increase in M, α increases. On the left, the diagram shows a vertical strip for connecting (gluing) the left and right sides of the workpiece, it can be of arbitrary width.

The most functional forms of construction are 4-sided and 6-sided. The production of such forms is possible from paper, plastic, paper with plastic. Technologically, it is possible to sequentially implement the design formation procedure on special machines with subsequent attachment of the bottom of the mold. But more productive is the one-time (in one technological step) blowing of a plastic blank (plastic, or plastic with paper, or other technologically suitable materials). This blowing is possible in a mold repeating the given shape of the structure immediately with the bottom. In this case, plastic is understood as the entire set of plastic masses in the form of films with sufficient elasticity.

The utility model formula also includes polygonal designs with rounded corners. In Fig.5 shows a shape with a triangular profile in the horizontal plane, Fig.6 - with a quadrangular profile in the horizontal plane. Polygonal constructions in the horizontal plane with rounded corners with a large number of faces are possible: 5, 6, 7, and so on up to an absolutely round section. Perhaps more complex forms - a star, an ellipse, a rhombus, and so on in a horizontal section.

A set of utility model forms with rounded corners is more technologically advanced for single-use molding with the bottom on the machine when using different types of plastic or plastic with paper as material.

The utility model formula also includes horizontally corrugated “barrel”, “cone”, “hourglass” shapes with extension or contraction along the vertical axis. Such shapes can be axisymmetric (with a circle in horizontal sections) and not axisymmetric polygons with sections with 3, 4, 5, 6 or more faces. 7-9, these structural shapes are shown taking into account axial symmetry. On Fig shows a shape in the form of a barrel, in Fig.9 shows a shape in the form of a truncated cone, Fig.7 shows a shape in the form of an hourglass.

All the above-described structural forms of the utility model are distinguished by the functional ease of changing the volume. As extreme forms of equilibrium, they have three positions. The state of "mini" - the maximum compression of the corrugations (Figure 10), the state of "midi" - half-opening (Figure 11), when the form is freely placed on a flat surface, the state is "maxi" (Figure 12), when the form is maximally filled. When measuring the shape volume of the utility model on completed product samples, it turned out that the shape volume varies quite significantly (from 10 to 30 times) in comparison with the “mini” situation and the “maxi” situation.

The advantage of the design is sufficient rigidity, due to its shape (stiffeners - corrugations).

Note that the mechanical stresses in the corners of the structural forms (FIG. 1, FIG. 5) are the higher, the smaller the number of faces of the structural forms, especially with angular shapes. An increase in stress in the corners due to a decrease in the number of faces does not mean anything for the operational characteristics of the utility model, since the products are supposed to be mostly disposable, but can make production a little more expensive due to the need to use more elastic materials and somewhat more complex equipment. At the same time, structural shapes with corners are more ergonomic.

The optimal volume of the proposed utility model is from 0.2 to 2.0 liters.

The technical result is the expansion of the arsenal for the collection of household trash desktop execution with a variable volume. The technical result also lies in the fact that the proposed utility model is very ergonomic for the scope of its application. In particular, it qualitatively changes the volume during operation, takes up very little space when folded, little space when unpacked, and significantly, up to 30 times increases the volume when fully filled.

An important technical result is also the simplicity of form and production, which makes it possible to realize the principle of disposability due to the low cost of production.

The technical result is also that hygiene requirements are observed to a large extent due to the principle of disposability.

The technical result in the performance of a utility model with the upper part folded in the form of a scallop lid is to reduce the likelihood of spilling out of the contents, preventing the spread of odors, dust, splashes and other undesirable consequences of storage.

The utility model is applicable and feasible, because can be manufactured on any known technological equipment, both in mass production and in small batches, and used in various sectors of the economy and society.
