Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of patterned cookware such as ladle, ladle, scoop net, patterned pan, and large fork for cooking, which are used for cooking.

[0002]

2. Description of the Related Art Conventional scooping nets used for food cooking are nets such as wire netting and bamboo netting attached to a support frame, and an extended portion of the support frame is attached to a wooden or bamboo handle. It is fixed to the handle by means of winding with a thin wire. Wooden and bamboo patterns tend to absorb moisture and become difficult to dry and become unsanitary, and there is a problem that the wound thin wire is missing and mixed into food. Further, the scooping net is discarded early because it is not relatively durable. However, since both the head and the handle are discarded at the same time, there are uneconomical and environmental problems. In addition, a cooking ladle is known in which a cylindrical wooden handle is inserted and fitted into a tubular connecting portion fixed to the head made of metal, plastic, or the like, and attached with a wood screw or the like through the connecting portion. Have been. The reason why the connecting portion is tubular is that it is easy to manufacture both the head and the handle, and it is easy to connect and insert these components to each other. However, if the connecting portion is a circular tube, the turning force applied in the direction around the axis of the handle when using the tool will be applied to the wood screw,
During use, the wood screws are loosened and sometimes fall off, causing problems such as the wood screws being mixed into the food material and the head falling off. In addition, when cooking foods, it is necessary to detach the head and handle for cleaning because the foods soak into the fittings and leave them unattended, but it is inconvenient to attach and detach the wood screws. On the other hand, there has been a problem that the wood screw does not work effectively and is easily detached when the attachment and detachment are repeated.

[0003]

SUMMARY OF THE INVENTION The present invention facilitates cleaning by making the head and handle easy to attach and detach, and the member for fixing the head and handle drops off during use and is mixed with food. The goal is to improve the durability and hygiene by coating the handle with plastic, and to improve the economic efficiency by allowing only the damaged head or handle to be discarded and replaced. And

[0004]

[Means for Solving the Problems]

According to the present invention, the above-mentioned object is achieved by the following means. That is, the first means is, in a cooker with a handle having a tubular connecting portion for connecting the head and the handle portion, a through hole is provided in the handle portion of the tubular connection portion, the through hole penetrating the cross section thereof, A female cooker with a female screw formed in the through hole, and a bolt corresponding to the female screw and fixing a head and a handle. By this means, washing by separating the handle and the head becomes easy, and the hygiene can be improved. The second means is a handle-equipped cooker having a female screw formed by burying a nut corresponding to a bolt in the through hole, and the third means is a tubular connecting part for connecting the head and the handle. The cross-sectional shape of the cooking utensil is a polygonal or elliptical cross-section, the fourth means is a cooking utensil having a plastic wall around a through hole provided in the handle portion of the tubular connecting portion. The fifth means is a handle-equipped cooker in which a head is made of a net-formed product having an aggregate provided on at least a peripheral portion and / or a bottom surface, and a tubular connecting portion is fixed to a part of the aggregate.

[0006]

According to the first aspect of the present invention, since the head and the handle are connected by a tubular connecting portion, the connection strength is further improved as compared with a conventional wire winding method or a wood screw method. Since it is fixed by using a bolt which can be used repeatedly, its attachment and detachment can be made much easier. Furthermore, since the recess formed as a screw portion in the handle portion is formed as a through hole, the flushing water that has been poured can be discharged as it is, and internal cleaning is facilitated. In addition, since the washing water flows out without collecting, it becomes very sanitary. Also,
According to the second aspect of the present invention, by embedding the nut in the through hole, the fixing force by the bolt is further increased. According to the third aspect of the present invention, since the rotational force of the handle in the direction of the rotation axis can be prevented, the load on the bolt and the nut can be reduced, and if the shape of the connecting portion is the same as the handle, the operation of the handle can be performed. The performance is also improved. Further, in the invention of claim 4, the strength and watertightness of the handle portion in the tubular connecting portion are increased,
In addition, hygiene and durability are improved. According to the fifth aspect of the present invention, unlike a cooking tool whose head is made of a plate-shaped molded product, the bonding strength of the connecting portion is low in a case where the head is made of a net-shaped molded product. If it is fixed, the fixing force between the head and the handle can be increased.
