Description

The group of inventions relates to light industry and can be used in the manufacture of holiday decorations with a spherical surface, in particular Christmas tree decorations - balls.

Recently, holiday decorations have been increasingly used, in particular Christmas toys made of unbreakable materials, such as polymeric ones. However, the known methods of decorating jewelry do not allow a variety of images and colors to be created and, due to decorating materials, can limit the scope, for example, for children under 3 years old.

There is a method of decorating Christmas tree decorations, according to which a heat-shrink film is applied on a spherical base in the form of a section of a sleeve of a cylindrical shape with an image applied to it, and then the workpiece with a heat-shrink film placed on it is subjected to a joint thermal action in a tunnel heater. As a result of thermal exposure, the shrink film fits snugly to the workpiece (base), taking its shape. In this way, a decorated Christmas tree decoration is obtained, consisting of a spherical base and a decorative heat-shrink film attached to it with an image printed on it / application KR 20040077205, A47G 33/08, A47G 33/00, September 4, 2004 /.

The disadvantage of this method is the impossibility of complete shelter of the decorated surface. The disadvantage of jewelry made in a known manner is the presence of undecorated fields based on jewelry, which reduces its consumer properties.

The task of the group of inventions is to create a simple and cheap production of holiday decorations, in particular Christmas toys, which have an extended service life and are decorated with a wide variety of images (patterns, paintings, inscriptions, photographs, etc.) with the ability to satisfy any consumer demand.

The technical result from the use of the proposed method is to ensure 100% completeness of decorating the basis of the decoration.

The problem is solved, and the technical result is achieved due to the fact that in the method of applying a decorative coating on a spherical surface, the first heat-shrink film is applied to a spherical base in the form of a section of a sleeve of a cylindrical shape with an image applied to it, then the base with the heat-shrink film applied to it is subjected to a joint thermal exposure, after which the second heat-shrinkable film is placed in the form on the base with the first heat-shrinkable film in the direction perpendicular to the first e of a section of a sleeve of a cylindrical shape with an image applied to it and re-subjected to thermal action.

It is preferable that the ball obtained by extrusion-blowing method from polystyrene is used as a spherical base, and the thermal effect is produced by hot water with a temperature of 80-90 ° C.

The method is as follows.

On the spherical base (preform), the first heat-shrink film is applied in the form of a section of a sleeve of a cylindrical shape with an image applied to it, then the base with the heat-shrink film placed on it is subjected to a joint thermal action, for example, by dipping in hot water. As a result of thermal exposure, the shrink film fits snugly to the workpiece (base), taking its shape. Then, on the base with the first tight-fitting heat-shrink film in the direction perpendicular to the first, a second heat-shrink film is applied in the form of a section of a sleeve of a cylindrical shape, with the image applied to it and re-exposed to heat, for example by dipping in hot water. As a result of thermal action, the second shrink film also fits snugly both on the base and in places of contact with the first shrink film, taking the form of a base.

An example implementation of the method.

For the manufacture of Christmas tree decorations - decorative balls - as a spherical base use a workpiece obtained by extrusion-blowing method from a polymer "Impact-resistant polystyrene UPM-508 08 (unpainted)". The workpiece is made with a neck. Before inserting the first heat-shrink film onto the preform in the form of a segment of a sleeve of a cylindrical shape with the image applied onto it using a hand press and a stamp fixed in it, a hole for the base of the base is formed in it, then the first heat-shrink film is mounted on the workpiece by threading the base of the base through the hole in the first shrink film, after which the base, together with the shrink film mounted on it, is dipped into water at a temperature of 90 ° C. The process of shrinkage of a decorative film occurs almost instantly. As a result of thermal exposure, the shrink film fits snugly to the workpiece (base), taking its shape. The blank with the first layer of decor applied is taken out of hot water. The resulting product is a ball with a decorating strip passing through the neck of a spherical base. The application of the first shrink film does not allow covering the entire surface of the spherical base intended for decoration. A second heat-shrink film is applied to the cooled base with the first heat-shrink film fixed on it in the direction perpendicular to the first, made in the form of a segment of a sleeve of a cylindrical shape, with the image applied on it so that all previously undecorated fields of the base are covered, and again subjected to thermal action by dipping in hot water with a temperature of 90 ° C. As a result of thermal action, the second shrink film also fits snugly both on the base and in places of contact with the first shrink film, taking the form of a base. Thus, the proposed method of applying a decorative coating on a spherical surface allows you to achieve 100% decoration of the surface of the ball.

The tight fit of the layers of shrink film allows you to get a festive decoration with an increased service life, because violate the integrity of the decor is quite difficult.

The image applied to the shrink film and its color scheme can be very diverse: reproductions of paintings, greeting inscriptions, anniversary and other symbols, photographs, ornaments, etc., and for Christmas decorations, various New Year plots, which makes products manufactured according to the proposed method, especially attractive to consumers.

The proposed method of applying a decorative coating on a spherical surface allows us to ensure 100% completeness of decoration of the basis of decoration using full-color printing, which also leads to an improvement in the consumer properties of holiday decorations.

The decorative product obtained by the proposed method consists of a spherical base equipped with two decorative elements applied to it, the axes of which are mutually perpendicular and used as a shrink film with an image applied to it.

The decorative product may be made of a spherical base, which contains a neck equipped with a spring.

It is preferable that the decorative product with a neck is provided with tinsel decorating the neck.

The group of inventions is illustrated by drawings.

Figure 1 - schematically shows the sequence of technological operations for obtaining a decorative product - a ball with a decorative coating applied to it; figure 2 - the same for decorating a ball with a neck and a spring - Christmas tree decorations.

The decorative product (Fig. 1) consists of a spherical base 1 provided with two decor elements: a first heat-shrink film with an image applied to it 2 and a second heat-shrink film with an image 3 applied to it, while the axes of both heat-shrink films are mutually perpendicular.

The Christmas-tree decoration (Figure 2) consists of a spherical base 1 provided with a first heat-shrink film with the image 2 applied on it and a second heat-shrink film with the image 3 applied on it, while the axes of both heat-shrink films are mutually perpendicular. The spherical base 1 comprises a neck 4 provided with a spring 5. Tinsel can be used to decorate the neck 4 (not shown in FIG. 2).

The surface of the resulting Christmas tree decoration is fully decorated.

A decorative product obtained by the claimed method is inexpensive, has an extended service life and is decorated with a wide variety of images (patterns, paintings, inscriptions, photographs, etc.), a festive decoration that can satisfy any consumer demand.

The spherical base of the decorative product - holiday decoration - can be made of plastic, glass, metal, wood and other materials. However, the use of plastic, in particular polystyrene, is preferred since it is inexpensive and does not break during use.

Thus, the proposed group of inventions allows you to create a simple and cheap production of 100% decorated holiday decorations, in particular Christmas balls with a wide variety of decorative patterns, with the ability to satisfy any consumer demand.
