Description

The utility model relates to the field of glass industry and can be used in the manufacture of glass containers, in particular, bottles for various drinks.

Known art and design solution "Bottle" according to the patent of the Russian Federation for industrial design No. 45811, class MKPO 9-01 declared on 08.21.97, published on 07.16.99, Bull. PMPO No. 7, p.92, patent holder of CJSC “Fora Trading”, author Volke Horn (DE).

This bottle is characterized by: - the composition of the composite elements: corolla, neck, body; - a cylindrical body with rounded shoulders, decorated with relief elements:

- the presence on the neck of a curly thickening; - the execution of a whisk under the screw plug.

The bottle is distinguished by: - the conical shape of the neckline expanded; -in the implementation of the shoulders of a spherical shape, extending beyond the vertical contour of the bottle; - development of a decor on the shoulders in the form of longitudinal recesses of strips dividing the shoulders into four sectors and turning into a transverse wide flat groove with the relief inscription "Dynasty" symmetrically located on two opposite sides; - conically rounded completion of the shoulders with the transition to a deep annular strip along the surface of the body; - the presence in the lower part of the body of a deepened strip with a cone-shaped base protruding beyond the vertical outline of the body, with a smooth transition to the bottom; - the execution of the bottom concave with corrugation along the edge.

The closest claimed utility model is an art-design solution according to the RF patent for an industrial design “Set of bottles (two options)” No. 51002, class MKPO 9-01, declared September 16, 2002, Bull. PO No. 9, p.113, authors Grideva I.V. and Petrashchuk L.V.

This set of bottles is characterized by: - the composition of the composite elements: whisk, neck, coat hanger, body and bottom; - a typesetting solution of three bottles made in a single style key and differing in proportional sizes, volume and decoration; - plastic study of the shape of each bottle: with a conically tapered body down and a neck - conical in the upper part; - decorating the bottom of the bottle body with faces;

Each of the bottles differs from the closest analogue: - plastic processing of the shape of the neck with a smooth thickening in the bottom

parts tapering down; - the presence of an annular convex girdle located between the neck and shoulders of the bottle; - the presence in the lower part of the case of a cone-shaped base, expanded from bottom to bottom, gradually turning into the bottom; - development of decor in the form of fourteen flat faces contacting each other with their sides, bounded above and below by radial concave curves and placed above the base; - the implementation of the corolla conical shape with a screw thread.

The second version of the set of bottles is characterized by the presence on the shoulders of the decor, designed in the form of a small indentation of a rectangular shape with rounded corners, in which the numbers "1922" are placed; - the execution of the bottom of the direct groove located on the side of the digital decor.

This artistic design decision is taken as a prototype.

The disadvantage of the prototype is the low mechanical strength of the bottle due to the occurrence of significant internal stresses in the zones:

- transition of the conical part of the neck to its smooth thickening in the lower part;

- transition of the thickened lower part of the neck into the annular girdle;

- pairing the bottom of the annular belt with the shoulders of the bottle;

- pairing the bottom of the bottle body, decorated with flat faces, with the base.

The problem solved by the utility model is to increase the mechanical strength of the bottle by reducing internal stresses in the mating zones of its composite elements.

The task is carried out by the fact that in a bottle including a whisk for a screw plug, a throat widened downward with a smooth thickening in the lower part, tapering to an annular convex girdle located between the throat and rounded shoulders, a body made in the form of a truncated cone, narrowed downwards, and the base expanded from top to bottom and smoothly passing to the bottom, the neck is made along a curved convex generatrix, the zones of conjugation of the annular belt with shoulders are made along the forming arcs of circles whose radii selected from the relation

R ₁ / R ₂ = 1.8 ... 2.2, where R ₁ is the radius of the circle whose arc is the generatrix of the mating zone of the annular belt with the shoulders of the bottle, R ₂ is the radius of the circle whose arc is the generatrix of the mating zone of the annular belt with the neck of the bottle,

and the interface between the bottle body and the base is made along a generatrix, the radius of which is chosen equal to the radius of the generatrix of the base expansion zone

R ₃ = R ₄ , where R ₃ is the radius of the circle whose arc is the generatrix of the interface zone of the bottle body with the base, R ₄ is the radius of the circle whose arc is the generatrix of the base expansion zone.

New significant features of the utility model are:

- execution of the neck along a curved convex generatrix;

- the implementation of the zones of conjugation of the annular convex girdle with shoulders and neck along the generatric arcs of circles whose radii are selected from the ratio R ₁ / R ₂ = 1.8 ... 2.2;

- the implementation of the zone of pairing of the bottle body with the base along a generatrix of a circle whose radius is chosen equal to the radius of the generatrix of the base expansion zone R ₃ = R ₄ . The execution of the neck along a curved convex generatrix allows to reduce the internal stresses arising in the zone of transition of the conical upper part of the neck to the bulge during the manufacture of the bottle according to the prototype, because the tapering of the upper part of the neck is practically eliminated and, as a result, the line of transition of the cone to the bulge, which is a stress concentrator, is eliminated there is no smooth pairing of neck elements.

Fulfillment of the zones of conjugation of the annular convex girdle with the shoulders and the neck of the bottle along the forming arcs of circles, the radii of which are selected from the ratio R ₁ / R ₂ = 1.8 ... 2.2 allows you to reduce internal stresses in these zones, at the same time allows you to strengthen the mating zone of the girdle with shoulders due to creating a smoother transition of the ring band into the shoulders of the bottle.

The fulfillment of the ratio R ₁ / R ₂ less than 1.8 at a given value of R ₁ increases R ₂ - the radius of the arc of the interface of the neck with the girdle, which will not allow to obtain the necessary pairing, will violate the design of the bottle.

The fulfillment of the ratio R ₁ / R ₂ more than 2.2 reduces R ₂ at a given value of R ₁ , which also affects the design of the product.

The implementation of the interface between the bottle body and the base and the zone of expansion of the base with arcs of the same radius ensures a smooth transition of one structural element to another, eliminates the dividing line and reduces local internal stresses in the finished product in this zone.

The effect of reducing local stresses in the material with increasing radius of the arc at the junction of different surfaces

known from the theory of resistance of materials, for example, from the course of N.M. Belyaeva “Resistance of materials”, GITTL, M. - L., 1950, pp. 6393-700.
