RU169674U1 - FOLDING SPOON - Google Patents

Abstract

The utility model relates to cutlery, namely to folding disposable environmentally friendly spoons, intended for the use of finished or quickly cooked foods. The folding spoon in the initial state is a flat pattern consisting of a head part, which forms a spoon cup when folding, and an elongated part with fold lines forming a spoon handle when folding. The elongated part has three fold lines directed from the outer edge of the elongated part toward the center of the head part in the form of a triangle, divided into two triangular sections, forming a spoon handle with a stiffening rib when folding. An adhesive layer is applied to the surface of one of the triangular sections, fixing the spoon in the assembled state. The proposed folding spoon is characterized by increased structural rigidity due to the presence of a stiffener and improved reliability of the retention of the shape of the device during use due to the presence of an adhesive layer. 11 s.p. f-ly, 5 ill.

Description

The utility model relates to the field of satisfying human needs and can be used, in particular, as cutlery, medical equipment, a device for dispensing bulk products, a device for mixing various substances.

Known cardboard lid of the container, which is transformed into a spoon (US patent No. 3931925, B65D 3/16, 01/13/1976), which is in the initial state a flat blank with cut out fold lines that allow after opening the container to transform the lid into a cutlery that performs the function spoons.

Due to contact with the product, this device loses its original operational characteristics and, when used, has low reliability due to the inability to hold the spoon in assembled form, as well as insufficient rigidity that does not allow the device to be used for solid products.

The closest analogue to the claimed device is a template for the construction of dishes (US patent No. 9131793, A47G 21/04, 09/19/2015), which is a paper blank on the surface of which symmetrical grooves are applied. When folding along the furrows, an object of dishes forms, which can be used as a spoon.

The disadvantage of this design is primarily low structural rigidity, which does not allow the use of the device for solid products. Since in the assembled state the device does not have a distinct bowl and handle of a spoon and is a paper scraper, this design limits the use of the device, for example, for liquid products. In addition, the disadvantages of this design include the impossibility of retaining the shape of the device during its temporary non-use, which leads to the need to use a new similar device.

The objective of this utility model is to eliminate these shortcomings and create a folding disposable tableware with improved performance.

The technical result achieved by the implementation of this utility model is to increase the rigidity of the structure due to the presence of stiffeners and improve the reliability of the retention of the shape of the device during use due to the presence of an adhesive layer.

The specified technical result is achieved due to the fact that the spoon is folding, in the initial state it is a flat pattern consisting of a head part, which forms a spoon cup when folding, and an elongated part with fold lines forming a spoon handle when folding, according to a utility model, the elongated part has three fold lines directed from the outer edge of the elongated part toward the center of the head in the form of a triangle divided into two triangular sections, forming a spoon handle with a rib when folding stiffness, while on the surface of one of the triangular sections applied adhesive layer fixing the spoon in the assembled state.

In a preferred embodiment, the device further comprises a protective element deposited on the adhesive layer, the stiffener is directed deep into the device, and the elongated part is a rectangle, the outer edge of which is made concave.

A folding spoon can be made of food cardboard, laminated cardboard, coated paper, litmus paper, edible bioplastics, polyvinyl chloride, any transparent plastic or cold rolled annealed sheet steel.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a folding spoon pattern, visas at the back, in FIG. 2 - an intermediate stage of folding the spoon, rear view; in FIG. 3 - a spoon when folded; in FIG. 4 is the same, rear view, in FIG. 5 - a pattern of a folding spoon with a protective element, rear view.

A folding spoon is arranged as follows.

Flat pattern 1 (Fig. 1) consists of a head part 2, which is preferably a semicircle, and an elongated part 3, representing a rectangle with three fold lines 5, 6 and 7. In a preferred embodiment, the outer short edge of the rectangle is made concave.

The bend lines 5 and 7 from the outer short edge of the rectangle are directed toward the center of the head part 2 and form a triangle 9 with a vertex 10. The bend line 6 divides the triangle 9 into two triangular sections 11 and 12.

The fold lines are cut in such a way that when folding the flat pattern, the fold line 6 (Fig. 2) rises above the flat pattern 1, and the fold line 11 is aligned with the fold line 12, thereby forming a stiffener 13 directed inside the structure (Fig. 3) and located along the entire length of the handle.

After these manipulations with a flat pattern from the head part 2, a bowl 14 of the spoon is formed, and from the elongated part, the handle 15 of the spoon with a stiffener 13.

To prevent decay of the structure during the non-use of the spoon, an adhesive layer 16 is applied to one of the two triangular sections 11 and 12 from the back of the flat pattern (Fig. 5).

In a preferred embodiment, the device has a protective element 17 that prevents premature bonding of two triangular sections with each other. As a protective element, waxed paper can be used. The shape of the protective element corresponds to the shape of a triangular section on which the protective layer is applied.

However, the protective element may not be. In this case, the adhesive layer is activated by wetting.

As the materials from which the spoon is made, materials such as food cardboard, laminated cardboard, coated paper, litmus paper, edible bioplastics, polyvinyl chloride, any transparent plastic or cold rolled annealed sheet steel can be used.

The production of folding spoons is very simple and requires a minimum of resources. The main steps are as follows:

preparation of cardboard, paper, bioplastics, polyvinyl chloride, plastic or sheet steel;

printing, for example, by offset method or flexographic printing (if necessary);

applying a laminated coating (if necessary);

die cutting of a flat pattern (blank);

felling of fold lines;

applying an adhesive layer to the necessary areas and applying a protective element to the adhesive layer.

In this way, an easy and technologically advanced manufacturing of a flat workpiece for a spoon is provided, which makes it possible to quickly and conveniently fold the workpiece into a spoon, characterized by improved performance characteristics. Thus, the proposed design provides the required rigidity of the spoon, allowing you to use the device for products of different hardness. When folded, the proposed spoon has a bowl and a handle, which allows the device to be used for various products, both solid and liquid. Short-term non-use of a spoon does not lead to structural decay, which is achieved through the use of a fixing (adhesive) layer, which, in turn, increases the reliability of the device.
