Abstract

The utility model relates to household items and tableware, in particular, to containers for preparing hot drinks and drinking them. An increase in heat-saving properties is achieved due to the implementation of heat-saving dishes in the form of two truncated cones: external and internal, each of which has a bottom and is made of a multilayer material, and the inner cone is coaxially located in the outer cone with the formation of a space between them and has a lower height and bottom diameter relative the outer cone, the edges of the cones are hermetically connected to each other, and the multilayer material contains a foil coating, cardboard and a polyethylene laminated coating. 3 C.p. f-ly, 4 dwg

Description

The utility model relates to household items and tableware, in particular, to containers for the preparation of hot drinks and their use.

Known heat-saving dishes (glasses), consisting of two truncated cones and a bottom. The cones are made of different heights with different lower and the same upper radii, glued and seamed in the upper part. The cones are made of a multilayer material containing, among other things, a polyethylene laminated coating (US 2015360845, 17.12.2015).

The disadvantage of this product is the loss of heat by the drink during prolonged use.

The technical problem to be solved by the proposed utility model is the creation of thermosaving cookware with improved performance characteristics, which eliminates the above disadvantages.

The technical result achieved by the implementation of the claimed utility model consists in increasing the heat-saving properties of the dishes.

The specified technical result is achieved in thermosaving dishes made in the form of two truncated cones: external and internal, each of which has a bottom and consists of a multilayer material, the inner cone is coaxially located in the outer cone with the formation of a space between them and has a lower height and bottom diameter relative the outer cone, while the edges of the cones are hermetically connected to each other, and the multilayer material contains a foil coating, cardboard and a polyethylene laminated coating.

The tight connection of the edges of the cones can be performed by ultrasonic welding followed by rolling of the upper edge of the product, which allows you to obtain a high-quality sealed seam that is resistant to mechanical stress and increases the heat-saving properties of the dishes.

The cones and their bottom (bottoms) have the following sequence of layers: the outer layer is a polyethylene laminated coating, an intermediate layer of cardboard and the inner layer is a foil coating with which the cones face each other, while, in the case of hermetically sealed layers by means of ultrasonic gluing, on foil coating applied laminated coating, which will increase the strength of the glued products. All this allows you to keep the temperature of hot drinks - tea, coffee, broth, etc., longer, and does not allow you to burn yourself, ensuring the consumer's comfort and protecting him from burns.

Additionally, the cardboard can be made three-layer (275 g / m ² ) in the form of micro-corrugated board or corrugated board.

The declared design of the utility model provides a high degree of heat-saving properties of dishes (glasses, plates, bowls, etc.) while maintaining safety during operation for the consumer due to the manufacture of dishes from two truncated cones of different heights with different lower radius and the same upper radius, rolled together in the upper parts with the formation of a gap between them and of a multilayer material, including a foil coating, additionally covered with a laminated layer, while it does not have a harmful effect on the human body and is capable of repelling about 95% of thermal radiation, retaining heat in the internal space / gap between the cones and the bottoms of the cones and not allowing high temperatures outside) and cardboard with a polyethylene laminated coating (due to its thermal insulation properties, cardboard retains heat well compared to dishes made of polypropylene, polystyrene and is safe for the consumer, and also does not burn hands, and polyethylene laminated coating digging protects against moisture and grease and provides sealing and, as a result, heat retention), which allows you to keep the temperature inside the dishes longer and increases its consumer properties.

The essence of the utility model is illustrated by drawings, where Fig. 1 shows a cutaway with a lid; in fig. 2 - multilayer material; in fig. 3, 4 - making dishes using the example of a glass.

Thermal-saving cookware consists of two truncated cones 1, 2: outer and inner, each of which has its own bottom 3, 4.

Each cone 1, 2 and its bottom 3, 4 is made of a multilayer material: the outer layer 5 is a polyethylene laminated coating, the intermediate layer 6 is made of cardboard, the inner layer 7 is a foil coating on which the laminated coating 8 is applied (for example, a polyethylene layer), which cones 1, 2 are facing each other.

The cones 1, 2 have different heights (the inner cone 2 is smaller than the outer cone 1) and the diameters of the bottoms 3, 4 (the bottom 4 of the inner cone 2 has a smaller diameter than the bottom 3 of the outer cone 1).

The inner cone 2 is coaxially located in the outer cone 1 with the formation of a space 8 between them, the edges of the cones 1, 2 are hermetically connected by ultrasonic welding and subsequent rolling.

For additional tightness, preservation of the warmth of the drink and the safety of the consumer, the dishes are closed with a lid 9.

Manufacturing method:

1. The cardboard is cut into blanks by a hydraulic punching press;

2. The blank for the outer cone is rolled up into a tube in the shape of a truncated cone with the metallized side inside the inner layer (foil coating), fixed with an overlap and glued (Fig. 3);

3. The bottom is glued to the resulting part with the metallized side, on which the laminated coating is applied, upward (Fig. 3);

4. The blank for the inner cone is rolled up into a tube with the metallized side outward and glued similarly to item 2 (Fig. 4);

5. The bottom is glued to the resulting part with the metallized side down (Fig. 4);

6. Both parts are glued together at the top / edges;

7. The upper edges of the product are hermetically connected by ultrasonic welding, followed by rolling of the edges.

Thanks to double walls, double bottom and inner metallized coating, the product keeps the temperature inside longer.

Surface bonding method: ultrasonic bonding (the machine heats up the laminated coating at the joint), due to which the surfaces are hermetically bonded.
