Tableware with reinforced structure and its process

The invention relates to a tableware and a process thereof, in particular to a tableware made of a ceramic material (such as chopsticks, a knife, a fork), and the tableware includes a reinforcing member to improve the overall hardness of the tableware.

According to the improvement of living standards, people pay more and more attention to the concept of health care. Among them, because tableware is the most frequently used in daily life, it is also the appliance that is most close to people's diet. Therefore, the health caused by tableware Hygiene issues are of concern to people. The main reason is that tableware is usually most in contact with food. Therefore, when tableware itself contains toxic substances, it will cause toxic substances in foods when it comes into contact with some foods, causing people to After eating, the health is damaged. In addition, when the cleaning method of the tableware is not correct, it may cause bacteria on the tableware, which makes it easy to infect the disease of the digestive tract. In view of this, many manufacturers have improved the existing tableware. To provide people with better and safer cutlery.

For example, afterwards, most of China's current eating habits use chopsticks as the main tableware for food picking. Among them, with the evolution of the times and material development, the existing chopsticks are also made in many materials, such as chopsticks made of bamboo or wood. Because it is low in cost and natural and non-toxic, it is widely used by people. However, the above-mentioned bamboo or wood chopsticks must be kept dry, otherwise it is easy to breed bacteria due to moisture. Therefore, for Taiwan, it is rainy and wet. In the season, if people wash chopsticks and do not put the chopsticks in a ventilated place to dry, it will cause bamboo or wood. The chopsticks are moldy and cannot be used. In addition, in addition to the above materials, some companies use copper, iron and other metals as the material of the chopsticks. However, the copper and iron materials may cause rust after long-term use, and the rusted substances after rusting (such as: If you enter the human body together with food, it may cause nausea, vomiting, poisoning, etc., which may endanger people's health. Therefore, in order to solve the above problems, some people will use stainless steel. Chopsticks to avoid people eating harmful rust substances, but stainless steel does not have rust problems, but because of its good thermal conductivity, if the user immerses the stainless steel chopsticks in the hot soup to pick up the hot food, It is easy to make stainless steel chopsticks warm and not easy to hold. In addition, stainless steel chopsticks are only metallic, and cannot change in multiple colors. If other colors of paint are applied to stainless steel chopsticks, the coating may be heated due to high temperature during subsequent use. The release of heavy metal substances affects the quality of food.

Therefore, it can be seen that the materials used for the production of chopsticks, such as bamboo, wood, copper, iron or stainless steel, still have a lack of use, resulting in poor user experience. Therefore, some manufacturers use ceramics as the material for chopsticks. The main reason is that the ceramic itself does not rust, and because of its high density, the surface of the ceramic is free of pores, so the juice of the food does not remain on the ceramic, making the ceramic chopsticks difficult to hide dirt or bacteria, and also It will not have odor or metallic taste, and has high hygienic quality. Moreover, due to the glaze on the surface of ceramic chopsticks, no chemicals or heavy metals will be released at 1200 °C. Therefore, when users use ceramic chopsticks When placed in a hot soup to pick up food, there is no problem that the ceramic chopsticks release toxic substances due to high temperature. Therefore, ceramic chopsticks are gradually favored by people. However, although ceramic chopsticks have the aforementioned advantages, when using ceramics as chopsticks, applicants have found that they generally encounter the following problems. First, due to insufficient structural strength of ceramics, ceramic chopsticks are frequently collided during use. Other utensils are prone to break the ceramic chopsticks into several segments; secondly, because the chopsticks are elongated, Therefore, when the ceramic is subjected to the sintering operation, it is easy to bend or deform during the forming process, and the ceramic chopsticks cannot be used, resulting in a decrease in the production yield, which causes the production cost of the manufacturer to remain high.

In summary, the existing ceramic chopsticks have the aforementioned problems in terms of use or production. Therefore, how to improve the above-mentioned defects is an important problem to be solved by the present invention.

In view of the above-mentioned shortcomings discovered by the applicant in the process of research and development of the tableware, the inventor finally designed the tableware with the reinforced structure of the present invention after years of practical experience and after many experiments and tests. And its process, the period can effectively improve the aforementioned deficiency.

An object of the present invention is to provide a tableware having a reinforced structure, comprising two tableware bodies and two reinforcing elements, wherein the tableware system is a columnar body made of a ceramic material, the top end of which is provided with an opening, and The opening extends inwardly to form a receiving space, the reinforcing member has a hardness greater than the hardness of the table body, and the part or the whole portion thereof can be positioned in the corresponding receiving space, and the periphery of the reinforcing member and the receiving space of the table body The inner wall is provided with an adhesive layer for fixing the reinforcing member, so that by providing a reinforcing member in the table body, the overall stress of the tableware (such as chopsticks, knives, forks, etc.) can be increased, and the When the tableware is in use, it breaks due to the collision.

Another object of the present invention is to provide a tableware process having a reinforced structure, wherein a ceramic material can be formed into a strip shape after the filling operation, and an opening is formed in a central position of the top end of the ceramic material, and The opening extends inward to form a receiving space, and then the ceramic material is sequentially subjected to air drying operation, sintering operation and temperature-removing operation to form a tableware body, Part or the whole of a reinforcing member is placed in the receiving space of the table body, and an adhesive is filled between the periphery of the reinforcing member and the inner wall of the table body to form an adhesive layer.
