Description

The inventive utility model relates to the production of disposable cutlery and can be used as accessories for disposable serving utensils made of plastic for receiving instant food products in disposable utensils, as well as finished products packaged in disposable containers.

A complex serving is known from the technical level, which includes the main part of the device and the handle. The main part includes the service part and the connection part, which is completely formed. Opening is provided at the outer end of the connecting part. Installation of the hole is provided upon opening. The handle is obtained by injection, extrusion, or melting and is rigidly connected to the connecting part [EPO No. 1586257, date publ. 10/19/05, bull. 2005/42].

A disadvantage of the known serving device is the high consumption of material and high cost.

Also known is a cutlery in the form of a spoon, used in combination with a container for yogurt, ice cream and the like. The spoon is made in the form of a longitudinal strip of elastic material and in a free state is curved in cross section so that its cross section lies on an arc of a circle inscribed in a central angle, the value of which lies in the range from 40 ° to 90 °, and the radius of the circle, on the arc of which lies the cross section of the spoon, is in the range from 20 to 30 mm. The ends of the spoon for the safety of its use are rounded. It can be perforated at one end to mix the product. Rigidity

spoon is selected so that it is enough to hold the food product or to mix. But at the same time, the elasticity allows it to be smoothed out, forming a flat strip for the purpose of attaching to the container. The spoon separated from the container under the action of elastic forces returns to its original shape, that is, it acquires the original radius of curvature in the cross section. This ensures the formation of a groove in which the food product will be held firmly [П RU for the invention No. 2290051, date publ. 2006.02.25]. The spoon is made by extrusion of the appropriate plastic materials. This method of manufacturing a spoon is the cheapest and virtually waste-free.

A disadvantage of the known spoon is its narrow functional orientation.

Known spoon for US patent No. 4216875, 12.08.80. The spoon is made in the form of an elongated strip curved in the transverse plane. The spoon is packed under the lid of the food container. For this, the end parts of the spoon are made with a rounded radius equal to the radius of the lid. Since the spoon has a certain curvature in the cross section, that is, it has a certain volume, there should be a place under the container lid for its placement. This leads to excessive consumption of material in the manufacture of the container, and there are also problems with observing the dimensions of the lid and spoon.

The closest set of essential features to the claimed utility model is a cutlery in the form of a monolithic folding plastic spoon of the Tetra Pak company, complete with the Wimm-Bill-Dann company product in the form of yogurt in a plastic container.

The product includes a working part in the form of a scoop of a shallow spoon with a connecting element and a movable handle. The product is folding

along the transverse line of transition of the connecting element to the movable handle. On the front surface of the connecting element along its longitudinal axis of symmetry, a recess is made above the scoop, the dimensions of which correspond to a volume retainer, which makes it possible to fix the spoon in the folded state. The latch is located along the longitudinal axis of symmetry of the spoon at a distance from the fold line equal to the distance from the fold line to the recess in the connecting element. On the wrong side of the spoon, the handle, the connecting element and the upper part of the working body are provided with stiffeners. The handle and the connecting element are seamlessly connected along the transverse connecting line by a thin flexible connection from the surface layer of plastic, which allows the spoon to be bent until the front surfaces of the working part, the connecting element and the handle contact. From the wrong side of the spoon, on the connecting element from above, one of the elements of the fixation unit is made - the fixation socket. For this, a partition is made across the connecting element with a height equal to the height of the stiffeners. On the bend from the wrong side, the handle passes into an additional fixing element in the form of a rectangle elongated along the longitudinal axis of the spoon, the width of which is less than the width of the fixing socket. The latch enters the latch socket from below.

A disadvantage of the known device is the significant cost due to the complexity of the mold for casting.

The objective of the claimed utility model is to expand the arsenal of disposable folding monolithic cutlery made of plastic for ready-made or quick-cooked food in a disposable container.

Technical results that can be achieved using the utility model are:

- the implementation of the appointment of a disposable folding monolithic cutlery made of plastic with a positive result;

- simplification of the manufacture of disposable folding monolithic cutlery;

- reducing the cost of the product.

The solution of this problem and the achievement of the above results was made possible due to the fact that in the well-known disposable folding monolithic tableware made of plastic for ready-made or quick-cooked food in a disposable container that includes a working part that passes along the longitudinal axis of symmetry into a rectangular connecting element, a handle equipped with the connection point with the fixing element monolithic with it and lying in the same plane, the stiffeners and the connecting fixing unit of the fixing and fixing nests, the rectangular connecting element has one common monolithic stiffening rib with the extended end of the handle lying in the same plane next to the working element, while the stiffening rib is bent at an angle at their junction, and the connecting fixing unit includes a through hole made as a fixing socket made in the upper part of the rectangular connecting element at a distance from its upper side, sufficient for the tight installation of a three-dimensional protruding pin, which is made integral with a latch on the side of its lower surface and perpendicular to it, while the latch on the side opposite to the monolithic stiffener is rounded, and the radius of rounding is equal to the distance from the inflection point on the outside of the monolithic stiffener to the point of intersection of the inner side of the composite stiffener with the upper side of the connecting item.

In a particular example of a disposable folding monolithic

the cutlery the working part is made either in the form of a spoon or in the form of a fork, and a slice of a composite stiffener is located above the upper side of the connecting element

The inventive combination of essential features allows you to rationally place the working body, the connecting element, the latch and the handle in one horizontal plane, which means to reduce the size and weight of the injection mold, simplify its design and, ultimately, reduce the cost compared to the prototype. The compact placement of elements of a monolithic cutlery in one plane also provides the smallest possible dimensions during packaging. The simplicity of the connecting fixing node and its reliability due to the tight fit of the volumetric protruding pin of the retainer into the hole of the connecting element allows to ensure reliability and ease of assembly of the final product. Radial rounding of the clamp on the opposite side of the common stiffener provides directional entry of the clamp between the straightened monolithic stiffener and the joined composite stiffener during assembly of the cutlery, while cutting a composite stiffener above the upper side of the connecting element contributes to a more rigid fixation.

The inventive cutlery is illustrated by the following figures.

The device is equipped with a composite stiffener 3, part of which is molded at the same time with the connecting element 2 and has a cut above its upper side 4 (Fig.1, 2), as well as a monolithic stiffener 5. These stiffeners protrude over the surface of the connecting element 2 and the handle 6 both on the front side and on the wrong side of the final product. The monolithic stiffener 5 is bent at an angle that allows the handle 6 to be compactly located in the same plane as the working part 1.

The connecting fixing unit (Fig. 2) consists of a fixing socket in the form of a through hole 7 made in the upper part of the connecting element 2.

The handle 6, from the connection side goes into the latch 8. The latch 8 on the wrong side, i.e. from the side facing the front surface of the working body, it is equipped with a volumetric protruding pin 9, for example of a cylindrical shape, cast at the same time with the lock 8 and perpendicular to it at a distance, ensuring a tight installation of this volumetric protruding pin 9 into the through

hole 7. The side of the latch 8 from the side opposite to the monolithic stiffener 5 is rounded. The radius of rounding is equal to the distance from the inflection point 10 on the outside of the monolithic stiffener 5 to the intersection point 11 of the inner side of the folding stiffener 3 with the upper side 4 of the connecting element 2.

Disposable folding monolithic cutlery is cast with a bent monolithic stiffener 5 in a simple flat mold.
