Description of the invention

The technical field to which the invention relates

The present invention is a method of manufacturing a vessel with a heat-insulating coating and products based on this method, in particular a technology that uses complex coatings mixed from a liquid binder and heat-foaming granular powders with the addition of paint, while such complex coatings are applied on the outer surface of the object, lies a foam layer, which binds to it in one piece under the influence of heating. In addition, such complex coatings can be applied according to the pattern model on the surface of the vessels, and three-dimensional patterns are formed, which creates numerous useful effects, in particular aesthetics, thermal protection, thermal insulation and protection against burns.

Former technology

Conventional vessels are mostly made of paper or plastic, taking into account their cost and purpose, for example: glasses, cups, plates, as well as packaging vessels made from these materials, heat-proof vessels, convenient containers, etc. These solutions are well known, while the technical solution described in the patent for the industrial design of the Republic of Taiwan No. 590114 was chosen as the closest analogue.

I Content of the invention

Solved problems

1. Such ordinary vessels described above are only single-layer, do not create heat-shielding and heat-insulating effects. If they were made folding two-layer or with an interval and at the same time were intended for single use, the cost would increase, which does not meet the requirement of minimum cost and maximum efficiency.

2. Conventional vessels are only single-layer and do not create heat-shielding and heat-insulating effects.

3. On ordinary paper or plastic vessels, the effect of three-dimensional embossed patterns for an aesthetic appearance can be achieved only by printing.

4. Currently, plastic cup holders are additionally used along with paper cups to protect against burns, for example, as a tray for a paper cup. This, of course, creates a burn protection effect for the person who holds the vessel, but it is inconvenient for the user due to the additional tray, in addition, such cup holders must be stored somewhere else, which also creates additional inconvenience.

II Means for solving these problems

1. The present invention is that

heat-foaming granular powders are added to the liquid binder and mixed, then these complex coatings are applied to the designated area of the rotating roll paper or to the surface of various formed vessels; then this roll paper or vessels are heated, and a foaming effect with the help of foaming grains takes place on their surface, at the same time this liquid bundle adheres to the surface of the vessels and a foam layer forms on the surface; then, parts are painted and vessels are made according to the applied paint templates, complex coatings can still be applied to the surface of vessels, for example paper and plastic vessels, which creates the effect of thermal insulation. Such vessels, when taking high-temperature substances, do not create a feeling of hot for the person who holds the vessel, have a heat-shielding effect and at the same time bring numerous beneficial effects: aesthetics, thermal protection, thermal insulation, protection against burns.

2. In addition, you can still draw drawings on the surface, that is, add paint to the specified complex coatings, apply them with a spray gun or using a rotating wheel device on the surface of the vessels. Coatings applied to parts with drawings, under the influence of heating, produce a foaming effect and form colored relief three-dimensional drawings, or after the formation of three-dimensional drawings, color printing can be performed to obtain a variety of beautiful visual effects. Such a surface layer has a heat-insulating function for the person who holds the vessel, and at the same time creates numerous beneficial effects: aesthetics, thermal protection, thermal insulation, protection against burns.

3. The present invention can be applied to the surfaces of different paper and plastic vessels, using the pattern model to form a variety of three-dimensional patterns, while achieving an aesthetic appearance and creating the effect of protection against burns, when a person holds the vessel for a place with embossed patterns.

4. The convexity of these relief patterns is determined by the thickness of the applied complex coatings, while the heating temperature is controlled within 80-160 ° C to meet the requirements of the relief patterns.

Method of implementation

For further acquaintance with the technical content of the invention, it is described below in more detail with one practical example of implementation.

As shown in FIG. 1, a method of implementing the present invention is that a liquid binder 2 is added to the heat-foaming granular powders 1, and after mixing 3 complex coatings 4 are formed, then coating is applied, for example, using a spraying unit 5, 5 'rotating device, 5' 'color printing, etc. These complex coatings 4 are applied to the surface of semi-finished products 6 (as shown in FIG. 2A) or vessels 7, 7 '(as shown in FIG. 2 B, C and FIG. 3 A-C), then the vessels 7, 7' are heated by means of a heating device 8, in this case a foaming effect occurs with the help of thermo-foaming granular powders 2, at the same time the liquid binder 1 adheres to the surface of the vessels 7, 7 'and a foam layer 9 forms on their surface (as shown in Fig. 4A), which has a strengthening effect and gives the effects of thermal insulation and heat Ita.

The above ligament 1 may be water or oil, both of these lubricants equally have the effect of hardening and adhesion.

As shown in FIG. 1 and FIG. 2, it is possible to directly establish a pattern on the drum 51 ′ of the rotary device 5 ′. Using the pattern model on the drum 51 ′ of the rotary device 5 ′, complex coatings 4 are applied onto the continuously produced paper P from the continuously unwound roll of paper P ′, then the prefabricated vessel 6 (as shown in FIG. 2A) can be cut out from the vessel 7 and the vessels can be made (the process of manufacturing vessels is not the subject of the present invention and therefore is not described in detail here); then the vessel 7 (7 ') is heated and a foam layer 9 is formed on its surface.

As shown in FIG. 1, FIG. 2, FIG. 4, using the above method, complex coatings are applied to the surface of a paper vessel 7 or a preformed plastic vessel 7 ′ and give a heat-insulating effect so that the person who holds the vessel does not experience a burn sensation when a substance with a high temperature is in the vessel, and at the same time creates a heat-shielding effect. In addition, as shown in FIG. 3 A-C, patterns of patterns for spraying or applying by means of a rotating device (Scheme 1, 2) of the above coatings on the surface can also be applied. In this case, complex coatings 4 applied to parts with patterns, after heating by the heating device, produce a foaming effect, forming convex three-dimensional patterns 9. These patterns have a heat-insulating effect for the person who holds the vessel, and at the same time create numerous useful effects, namely aesthetics, thermal insulation , heat and burn protection.

As shown in FIG. 1, FIG. 2 A-C, FIG. 3 AC, FIG. 4 AC, it is possible to apply complex coatings 4 to any places for holding and parts of vessels 7 (7 ') partially, and not completely; it is also possible to make cavities 71 (71 ') when forming the vessels (see Fig. 4C), apply complex coatings 4 to the corresponding cavities 71 (71'). Complex coatings 4 after heating and foaming will fill these hollows of the vessels 71 (71 '), restoring the smooth state of their outer surfaces and thereby creating a burn protection effect. At the same time, the cost of production is reduced.

As shown in FIG. 1, FIG. 3 A-C, and FIG. 4 A-C, paint 11 can be added to the above coatings 4, with multicolor patterns appearing at the place of foaming; you can still apply complex coatings 4 on the surface of the vessels 7 (7 '), after foaming and bonding to produce color printing 5' ', while on the foaming place (pigv) C foam layer 9 or on the entire surface of the foam layer 9 (Fig .4A) color patterns appear.

The convexity of the above three-dimensional patterns is determined by the desired thickness of the relief after foaming at a heating temperature of 80-160 ° C.

These practical examples of the application of the present invention, including applications for various paper or plastic vessels, for example glasses, cups, plates and other packaging vessels, as well as their effects - thermal insulation, thermal protection, protection against burns and the effect of strengthening, are presented only for illustration and do not limit the scope of the present invention, which is determined by the attached claims.
