Description

 The invention relates to the food industry and is intended for the storage of transparent liquids, mainly carbonated drinks.

 Glass bottles are known for storing food liquids (GOST 10117-91).

 The disadvantage of these bottles is that they can only be used for their intended purpose - to store liquid.

 From optics magnifiers are known. A magnifying glass is an optical system consisting of a lens or several lenses designed to observe objects located at a finite distance (N.P. Zakaznov and other Theory of Optical Systems. M.: Mechanical Engineering, 1992, p. 190). They are also used for the concentration of sunlight.

 The task to which the invention is directed is to improve the consumer qualities of the bottle and give it new functionality.

 The technical result of the invention is to give the bottle the properties of a magnifier.

 The aforementioned task is achieved by the fact that the walls of the bottle body are made of transparent material by axisymmetric optical refractive surfaces (for example, second and higher order spherical surfaces, as well as flat), so that the symmetry axes of the refracting surfaces lie on one imaginary straight line, the so-called optical axis . When performing refracting the external and internal surfaces of the walls of the housing, i.e. when executed in the form of two separate lenses, they, together with the liquid contained in the bottle, form a complex optical system, the so-called collective lens. When only the external surfaces of the body walls are made optical, the refractive index of the material from which they are made must be equal to the refractive index of the liquid contained in the bottle (their optical density must be the same), and then the internal surfaces in contact with the liquid can have an arbitrary shape. In this case, the walls of the bottle body (or rather their outer surfaces) together with the liquid contained in it form a simple lens.

 The technical result of the invention can be achieved only by forming the bottle body in the form of a lens, when the walls of the body together with the liquid contained in the bottle (or only their outer surfaces) form a magnifying glass.

 In the case of optical performance of the external and internal surfaces of the walls of the body (in the form of two lenses), the technical result of the invention can be saved even after emptying the bottle. In this case, the optical power of the lens will change slightly.

 When the walls of the casing of a bottle-magnifier are made of an elastic material (for example, polymeric) with the ability to elastically deform, it becomes possible to change the optical power of the magnifier by changing the geometric dimensions of the bottle, for example, by pushing one wall of the body inward along the optical axis. The flattening of the bottle and the change in the curvature of the walls of the casing occur, which causes a change in the optical properties of the bottle-magnifier.

 Since obtaining a high-quality enlarged image using large-sized loops is problematic (and in this case, the relatively large size of the bottle-magnifier is due to the need to ensure a sufficient amount of its contents), the author believes that the present invention will receive the main application as a concentrator of sunlight for kindling combustible materials ( for example, a bonfire in the field).

 The essence of the invention is illustrated in figures 1-3.

 Figure 1 presents a bottle-magnifier, consisting of a housing 1 and connected with a threaded connection of the cover 2, containing liquid 3 and a certain amount of gas 4. The walls 5 and 6 of the bottle body 1 are made of a transparent material having a refractive index equal to the refractive index liquids 3. The inner surfaces of the walls 5 and 6 have an arbitrary shape, and the outer surfaces are made spherical, the symmetry axis of these surfaces coincide, forming the optical axis 7.

 This bottle magnifier operates as follows.

 The bottle is oriented in space so that the wall 5 of the housing 1 is facing the sun. Parallel sun rays 8 and 9 are refracted on the outer surface of the wall 5, pass the liquid 3 contained in the bottle and, once again refracted on the outer surface of the wall 6, intersect at the back focus 10, where a high temperature zone is formed. Focusable 10 combustibles ignite.

 Figure 2 presents a bottle-magnifier, consisting of a housing 1 and connected to it by a threaded connection of the cap 2, containing liquid 3 and a certain amount of gas 4. The walls 5 and 6 of the bottle body 1 are made of transparent material, their inner and outer surfaces are made spherical , the symmetry axis of these surfaces coincide, forming the optical axis 7.

 This bottle-magnifier acts like a bottle shown in figure 1, except that the rays 8 and 9 are refracted not only on the outer, but also on the inner surfaces of the walls 5 and 6.

 Figure 3 presents a bottle-magnifier, consisting of a housing 1 and connected to it by a threaded connection of the cap 2, containing a liquid 3 and a certain amount of gas 4. The walls 5 and 6 of the bottle body 1 are made of a transparent transparent material that can elastically deform, internal and the outer surfaces of the walls 5 and 6 are made spherical, the axis of symmetry of these surfaces coincide, forming the optical axis 7. The wall 6 is shown dented into the body 1.

 This bottle magnifier acts as well as the bottles shown in FIG. 1 and 2, but, in addition, has the ability to change its optical characteristics (focal length and optical power). This is achieved due to the indentation of the wall 6 of the housing 1 with the lid open 2. The flattening of the bottle and the change in the curvature of the wall 6 occur in this case cause a change in the focal length and optical power. Closing the lid 2, fixing the internal volume of the bottle, prevents the restoration of the original shape of the wall 6.

 The possibility of industrial application of the invention does not cause doubt in the author.
