Background of the invention

1. Field of the invention

The present invention relates to composite cutlery elements, such as. Soup spoon, Forks, knives, bottle opener etc.

2. Description of the state of the technique

cutlery is a daily one Need for modern People; it does not just serve as an elemental tool when taking daily Meals, but enhanced by its good appearance also the state of mind when taking meals. Heartfelt family gatherings for dinners, successful business Lottery companies or happy parties with friends are often through the use of cutlery with a select design more attractive. Bad designed or manufactured cutlery, however, can take the make meals unpleasant, but may also cause e.g. Dirt is bad to remove, or that forks due to insufficient Strength break.

In order to produce special cutlery elements of selected beauty, the manufacturers forge have made investigations. Some improve the functions of the cutlery through special structures, some select selected designs as a feature and others even highlight colors or materials. However, in a nutshell, the manufacture of traditional cutlery can essentially be divided into two types of measures:
The first uses only one type of metal and sets the cutlery main elements according to 4 made in one piece by metal casting and forging. By using only one type of material, the articles have fewer variations. Due to the fact that metal materials have a higher density, articles made therefrom are heavier, which often makes the use more cumbersome and inconvenient. Furthermore, due to the metal material, it should be processed in a certain way during manufacture, usually by metal casting and forging. The cost of the entire process and equipment for manufacturing is extremely high, which makes the price of products made of metal material excessively high and poorly accepted by buyers.

at The second production method will be different types of materials used for the production of the cutlery main element. Generally be due of comfort when cutting and taking meals of the dining section the spoon and the fork section of forks are all made of metal. Around Cutlery more diverse To design, the handle elements of the cutlery are mainly made made of other materials, e.g. Wood, plastic or acrylic.

Connection structure and form of an embodiment conventional cutlery are in 5 shown. Here, the connecting part of the cutlery used has an elongated element A with a projection A1 and a recess 2, wherein the connecting portion of a handle B of the cutlery is provided with a hollow chamber B1 for inserting the extended element A. When bonding, the hollow chamber B1 is filled with adhesive or heated to be tightly closed, and then force is applied to insert the elongated member A into the hollow chamber B1. The projection A1 of the elongated member A then engages the hollow chamber B1 while the adhesive in the recess A2 reinforces the bonding force.

Connection structure and form of another embodiment conventional cutlery are in 6 shown. Here, the connection part of the cutlery used for eating is provided with an elongated element C and the connection part of a handle E of the cutlery has a hollow chamber E1 which is formed for the heated introduction of the elongated element C into the hollow chamber E1 under the action of heat ; the hollow chamber E1 is filled with adhesive and coupled to a surrounding frame D. By applying force, the elongated element C is then pressed into the hollow chamber E1, the elongated element C pressing into the adhesive in the hollow chamber E1 to completely fill it with the adhesive.

So the chamber and the elongated element C join together tightly and increase hence the strength the connection of the cutlery.

The connection modes of the two types of cutlery each have the part used for use with a protruding from this extended element. A force is exerted to introduce the elongated member by pressure into the hollow chamber and a handle. With adhesive filled into the hollow chamber of the elongated member, an object with a firm connection is achieved. In this compound obtained by pressure, however, the two parts are joined together with an external force. As a result, the connection area of the two parts can easily break, since there is concentrated pressure in this area. After the cutlery has been used for a while, the working area and the handle can easily become loose. Also, in this connection can be accumulating dirt and it is difficult to obtain both cleanliness from beauty and hygiene when in use.

Out the copyrights JP-A-01086908 or FR-A-2057106 is a method for producing a handle for a kitchen appliance known, in which a handle body with several through holes placed in a metal mold, whereupon a synthetic resin material is injected into the mold, through which the handle body to form a kitchen utensil handle integral with the synthetic resin is poured.

The TW-Y569738 and US-B-6607225 show a structure made of stainless steel made composite chopstick, wherein a stainless steel metal sleeve part with a handle body produced by injection molding.

Of the Handle connecting part has the shape of a truncated cone formed hollow cylinder, one end of which is close to the main body of the device a smaller area while, while the other is outward extending end has a larger area.
