[Embodiment of the invention]

 Hereinafter, an embodiment of a handle of a cooking utensil according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the handle of the present invention, and FIG. 2 is a longitudinal sectional view thereof. The handle 1 of the present invention is entirely made of stainless steel, has a grip portion 2 having an uneven shape on upper and lower surfaces, and has a closed hollow portion 3 provided therein. A connecting portion 4 is provided at one end of the handle 1, and a hooking hole 5 is provided at the other end of the handle 1.

The grip portion 2 is a portion having a function of gripping and holding the handle 1 of the present invention by hand. It is preferable that at least one of the upper and lower surfaces of the handle 1 is provided with an uneven shape, and the holding function is provided. When it is desired to further increase the surface roughness, it is preferable to provide the upper and lower surfaces with uneven shapes. This uneven shape can be used without any particular limitation as long as it is hard to slip when gripped and can hold the handle 1. For example, a shape in which gently shaped unevenness is alternately formed can be suitably used.

The closed hollow portion 3 refers to a sealed portion formed of an air layer formed inside the handle 1 of the present invention, and has a function of making it difficult to transmit heat to the handle 1, and the entire handle 1. This is the part where weight reduction is achieved. In order to simultaneously achieve the object of the present invention of lowering the thermal conductivity of the handle 1 and reducing the weight thereof, the closed hollow portion 3 exists over the entire handle 1 and has a volume as large as possible. Is preferred.

The connecting portion 4 is a portion for fixing a main body such as a frying pan or a pan (hereinafter abbreviated as “main body”) and the handle 1 by welding, and the connecting portion 4 does not pass through other connecting members other than the main body and the handle. It is provided when the body and the handle are directly connected. Therefore, when connecting the handle to the main body via another connecting member, it is not necessary to provide the connecting portion 4 on the handle 1. The connection portion 4 is preferably provided at one end of the handle 1 in consideration of practicality. The shape and size are not particularly limited as long as they do not hinder the welding. For example, the shape may be a substantially T-shaped shape that is substantially orthogonal to the grip portion 2. The size may be appropriately changed according to the size of the handle 1 or the like.

[0010] The hanging hole 5 is a hole to be hooked on a hook when the frying pan or the pan with the handle 1 is stored upright, and is convenient when the frying pan or the pan with the handle 1 is not used. It is provided as necessary in consideration of the above. In consideration of practicality, it is preferable that the hooking hole 5 is provided at one edge of the handle 1. When the hole 5 is provided along with the connecting portion 4, the connecting portion 4 is provided at one edge of the handle 1. It is a preferred embodiment to provide the hooking hole 5 at the other end of the handle 1. The shape of the hooking hole 5 is not particularly limited, but may be, for example, a circle, an ellipse, a square, a rhombus, and the like. The design may be changed and used.

Next, an embodiment of the method for manufacturing a handle of the present invention will be described. The handle 1 is manufactured by welding at least two or more hollow handle members having an opening part to each other. FIG. 3 shows an embodiment using a handle member 6 corresponding to one obtained by vertically dividing the vicinity of the center of the upper and lower surfaces of the substantially bar-shaped handle 1 into two. The handle member 6 has an opening 7 on the division surface and a hollow portion. The handle 1 is manufactured by manufacturing at least two or more divided handle members 6 in advance and welding the openings 7 of the handle members 6 to each other.

Next, a method for manufacturing the handle member 6 will be described. The handle member 6 is made of stainless steel and is manufactured by casting. For this reason, when manufacturing the handle 1, a model having the same shape as the handle 1 is made, and a mold is made using the model. This model is divided and provided for casting. After casting, the cast product extracted from the divided mold constitutes the handle member 6. For example, when the number of divided surfaces is one, two handle members 6 are manufactured and are used for subsequent welding. Here, the handle member 6 is a member formed by being divided along a certain surface of the handle 1 so that the internal cross section of the handle 1 appears. The division surface is not particularly limited. Preferably, when manufacturing the substantially bar-shaped handle 1, as shown in FIG. 3, the handle 1 may be divided along the short direction, or may be divided along the longitudinal direction of the handle 1. No. Although the number of division surfaces is not particularly limited, it is preferable that the number of division surfaces is one in consideration of simplicity of casting. Further, it is preferable that the thickness of the cross section of the handle member 6 is as thin and uniform as possible in order to reduce the weight.

Next, the handle 1 is manufactured by welding the openings 7 of the handle members 6 manufactured as described above to each other. Polishing the surface of the welded portion after welding is preferable in terms of smoothing the welded portion and improving the appearance of the handle 1.

The handle 1 of the present invention manufactured as described above has a conventional stainless steel having no closed hollow portion because the entire surface is made of stainless steel and most of the inner portion is provided with the closed hollow portion 3. The weight can be reduced to a considerable extent as compared with the handle. Further, the closed hollow portion 3 is filled with an air layer, and has a lower thermal conductivity as compared with a conventional solid stainless steel handle, so that a rise in the temperature of the handle portion can be suppressed low.
