Description

Background of the Invention


1. Field of the Invention



[0001] The present invention is related to composite tableware like table spoons, forks, knives and bottle cap openers etc.

2. Description of the Prior Art



[0002] Tableware is a daily necessity for modem people; it not only acts as basic tools for use in daily meals, but also gives good appearances to increase the mood in having meals. Sweet family gathering for dinners, successful commercial fellowship parties or joyful parties of friends often are endued with much attractiveness by using tableware of outstanding design. On the contrary, tableware from bad design or bad manufacturing may render displeasing in having meals, for example, it may have the result such as of dirt that is hard to clean or of breakage of forks being due to insufficient strength.

[0003] In order to manufacture a piece of beautiful and outstanding tableware, manufacturing smiths have paid efforts in hard study, some increase the functions of the tableware with special structures, some make outstanding appearances as their features, and some even emphasize colors and materials, however summarily, manufacturing of conventional tableware basically is divided into two kind of measures:

[0004] The first one uses only one kind of material of metal to integrally shape by founding and forging to make the main bodies of tableware, such as is shown in Fig. 4. Using only one kind of material renders the articles to have less variation. Because the virtue that metallic material has larger density, the article made thereof is heavier, and thereby this often renders a user more cumbersome and inconvenient in use. And more, by the feature of the metallic material, in manufacturing, it should be processed by a specific way, normally it is manufactured by founding and forging; the cost for the entire process and equipment for manufacturing is extremely high, thereby the price of the product made of metallic material is overly high and is hard to be accepted by consumers.

[0005] The second one uses different kinds of materials to make the main bodies of tableware. Generally, for the convenience of cutting and taking foods in meal times, the parts of spoons and the forked parts of forks, are all made of metal. In order to render tableware more abundant in variation, the handle parts of the tableware are mostly made of other materials such as wood, plastic or acryl.

[0006] The connecting structure and mode of a kind of conventional tableware is shown in Fig. 5, the connecting portion of the part used of the tableware is provided with a prolonged member A having a protrusion A1 and a recess 2, the connecting portion of a handle B of the tableware is provided with a hollow chamber B1 for insertion of the prolonged member A. When in connecting, the hollow chamber B1 is injected therein with adhesive or is heated to get tight closed, and then a force is exerted to forcedly insert the prolonged member A into the hollow chamber B1; the protrusion A1 of the prolonged member A then engages with the hollow chamber B1, while the adhesive in the recess A2 increases the connecting strength.

[0007] The connecting structure and mode of another kind of conventional tableware is shown in Fig. 6, the connecting portion of the part being used of the tableware is provided with a prolonged member C, the connecting portion of a handle E of the tableware is provided with a hollow chamber E1 adapted for heating insertion of the prolonged member C into the hollow chamber E1; the hollow chamber E1 is injected therein with adhesive and is coupled with a surrounding frame D, and then a force is exerted to forcedly insert the prolonged member C into the hollow chamber E1, the prolonged member C presses the adhesive in the hollow chamber E1 to fully fill the latter with the adhesive to tightly connect with the prolonged member C, to thereby increase the connecting strength of the tableware.

[0008] The connecting modes of parts of the both two kinds of tableware each have a utility portion with a prolonged member extending therefrom, a force is exerted to forcedly insert the prolonged member into the hollow chamber and a handle, and with adhesive filed in the hollow chamber of the prolonged member to get an object of tight connecting. However, this mode of connecting forcedly connects the two parts with an external force, and renders the connecting area of the two parts to be subjected to breaking by concentrated stress at this area, after using for a period of time, the utility portion and the handle are subjected to loosening; on the other hand, this connecting area is subjected to have dirt accumulated here, and it is hard to maintain neatness and beauty as well as sanitation in use.

[0009] From JP-A-01086908 or FR-A-2057106 a method for production a handle of a kitchen utensil is known wherein a handle body with various through-holes are placed in a metal mold whereafter a synthetic resin material is injected into the mold space by which the handle body is integrally molded with the synthetic resin to from a handle of the kitchen utensil.

[0010] TW-Y569738 resp. US-B-6607225 shows a structure of a stainless composite chopstick defining a stainless steel metallic sleeve portion combined with a handle body by injection molding.

[0011] The handle-connecting portion has the form of a hollow barrel designed as a truncated cone of which an end near the main part of the utensil has a smaller area, while the other end extending outwardly has a larger area.

[0012] However, that known structure is not designed for tableware like knifes, forks or spoons which have to withstand severe side forces.

[0013] In view of the above defects to be solved for providing a novel piece of composite tableware the inventor provides the present invention based on his professional experience of years in repeated experiments and improvement.

Summary of the invention



[0014] The primary object of the present invention is to provide a piece of a composite tableware, consisting of different materials, having good appearance, durability and good connecting strength and which can be produced with reasonable cost of production.

[0015] The components of the present invention include a main part of a utensil and a handle; said main part of said utensil is integrally shaped and is made of metal and is formed by punch pressing. One end thereof has a utility portion, designed as a spoon, a fork or a bottle cap opener. A handle-connecting portion extends to a direction away from said utility portion, said handle-connecting portion being in the form of a hollow barrel and at least having a fixing hole. An opening being provided on an outer end of said handle-connection portion. Said handle is formed by injection shaping, extruding as well as melting, and is tightly connected to the interior of said handle-connecting portion through said opening and extending outwardly to complete said handle for holding by a hand and integrally connecting with said main part of said utensil.

[0016] The present invention will be apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
