Chopsticks are China and the used a kind of prevailing tableware of Asia part country's catering trade, and are especially true in China, we can say that the three meals in a day people be unable to do without it.From ancient times to the present, our chopsticks of use mainly contain bamboo matter, wooden chopsticks.In recent years, have again plastics chopsticks, resemble bud chopsticks, metal chopstick.But their common feature is to be solid.Though bamboo matter, wooden chopsticks cost of manufacture are not high, have following deficiency: the one, rough surface, rough is easily hidden dirt, and sanitation performance is poor; The 2nd, yielding after the high-temperature sterilization, variable color had both influenced the function of the normal holding foods of chopsticks, had brought inconvenience to the user again, and gave a kind of antihygienic sensation of people, influenced appetite of people; The 3rd, of low grade, bamboo matter, wooden chopsticks only are applicable to general family and common restaurant, are not suitable for dinner party and high-grade hotel and use; The 4th,, waste a large amount of bamboos and timber, be unfavorable for protecting the environment and the ecological balance.Plastics chopsticks have easily to be faded, easily moves back bright, aging fast, the life-span short after the high-temperature sterilization, and can produce harmful substance, now withdraws from the market substantially.Metal chopstick because of being solid, is not only wasted a large amount of non-ferrous metals, but also have heat transfer rate fast, scald one's hand, scald mouth, deficiency that weight is big.As aluminium matter chopsticks, except that the general character with solid metal chopsticks, also the easy oxidation blackout in tool surface is not attractive in appearance, simultaneously also easily by acid, alkali, salt corrosion, generates harmful substance.Resemble bud chopsticks,, can not generally use though the class height because of being cost by sacrificing elephant, can only be used as handicraft.

The purpose of this utility model is, provides a kind of attractive in appearance, indeformable, any surface finish, easy cleaning, heat transfer rate is slow, weight is moderate, helps protecting environment and the healthy metal chopstick of people.

The purpose of this utility model reaches by the following technical programs.This metal chopstick is made up of chopsticks body 1, and its special character is that described chopsticks body 1 is hollow, and the length of its hollow parts accounts for 1/2nd of chopsticks body total length at least.Here used metal should have that nontoxic, intensity is big, good stability, not oxidation, the characteristics of not corroded by materials such as acid, alkali, salt, and also the low metal of thermal conductivity factor is better.As the 1Cr13Ni9Ti stainless steel of international popular, and metal, alloy material with above characteristics.The shape of chopsticks body 1 can be thick cylindric of upper and lower grade, also can be upper and lowerly not wait slightly like cone-shaped, can also be, middle epimere is many ribs shape, and hypomere is cylindric, and the centre is the shape of round table-like changeover portion.

Described chopsticks body 1 be hollow all.

The length of described chopsticks body 1 hollow parts accounts for 4/5ths of its total degree.

The wall thickness of described chopsticks body 1 is 0.3～0.5mm.

Because the utility model is designed to hollow shape with chopsticks body 1, make the weight of metal chopstick moderate, and heat transfer rate is slow, the speed of its heat transfer rate and bamboo matter, wooden chopsticks is suitable, non-scald on hand, do not scald mouth, but also have attractive in appearance, indeformable, nondiscolouring, bright and clean, easy cleaning, the easy characteristics of sterilization.Both improve the class of chopsticks, and can save a large amount of metals again, can also reduce the consumption of bamboo, timber in a large number, helped environmental protection.

The explanation of accompanying drawing drawing:

The structural representation of the another kind of chopsticks of Fig. 3---the utility model

The A-A profile of Fig. 4---Fig. 3

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.Embodiment 1, with reference to figure 1, Fig. 2, this is that a middle epimere is that four rib shapes, hypomere are cylindric, the middle metal chopstick of round table-like changeover portion that is, be to be the hollow chopsticks of stainless steel of 0.5mm with the wall thickness that the 1Cr13Ni9Ti stainless steel is made, the length of its hollow parts equals the length that chopsticks body 1 length deducts its two ends wall thickness.Product draws high-pressure molding through special equipment, forms through glossing.

Embodiment 2, with reference to figure 3, Fig. 4, this be chopsticks body 1 epimere for slightly cylindric, hypomere is for carefully cylindric, the middle part is with the metal chopstick of round table-like changeover portion, promptly like cone-shaped metal chopstick.Be to be the hollow chopsticks of stainless steel of 0.3mm with the wall thickness that the 1Cr13Ni9Ti stainless steel is made.But it is solid that its hypomere head accounts for the part of chopsticks body 1 total length 1/5, and all the other 4/5 parts are hollow.Process is substantially the same manner as Example 1.

In like manner, according to the technical solution that the utility model provides, can also provide the hollow parts made from stainless steel or metalloid material and account for chopsticks body total length 1/2 to whole, its wall thickness is the metal hollow chopsticks between 0.3～0.5mm.What of metal hollow chopsticks parts, both relevant, also relevant with the wall thickness of chopsticks body with the density of metal material.Ordinary circumstance, the density metal height, hollow parts is many, and is whole until the chopsticks body, on the contrary, density metal is low, hollow parts is few, but minimum be 1/2 of chopsticks body total length.In like manner, for using the metal chopstick made from a kind of metal material, the chopsticks body wall is thick, and hollow parts is many, and is whole until the chopsticks body.The chopsticks body wall is thin, and hollow parts is few, but minimum be 1/2 of chopsticks body total length.
