Description

[Technical Field]

[0001] This invention relates to a cooking ladle used for cooking various dishes. [Background technology]

[0002] In school lunches, employee cafeterias, restaurants, etc., large-capacity ladles are used to prepare soups and other dishes.

[0003] Conventional ladles of this type have been made entirely of stainless steel, which makes the ladles themselves very heavy and difficult to handle, placing a strain on the cook. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made in light of the above circumstances, and its object is to provide a cooking ladle that can reduce the burden on cooks. [Means for solving the problem]

[0005] A cooking ladle according to one embodiment includes a container and a handle welded to an outer surface of the container, the container and the handle being made of titanium.

[0006] For example, the handle is a hollow pipe and the thickness of the container is less than the thickness of the handle.

[0007] Preferably, the thickness of the container and handle is less than 1.0 mm.

[0008] For example, the inner diameter of the upper edge of the container is 150 mm or more, and the length of the handle is 500 mm or more.

[0009] The edge of the container may have a shape including a first portion bent downward and a second portion that curves up from the tip of the first portion into the space between the side of the container and the first portion. [Effects of the Invention]

[0010] According to the present invention, for example, a cooking ladle can be provided that can reduce the burden on cooks. [Brief explanation of the drawings]

[0012] An embodiment of the present invention will be described with reference to the drawings.

[0013] 1, 2, 3 and 4 are respectively a schematic perspective view, a top view, a side view and a rear view of a cooking ladle 1 according to this embodiment.

[0014] As shown in these figures, the cooking ladle 1 comprises a container 2 and a handle 3. The container 2 is, for example, round, and has curved sides 21, a flat bottom 22, and an edge 23 at the upper end of the side 21. Note that the container 2 is not limited to being round, and various shapes may be adopted.

[0015] As shown in Figure 2, the side portion 21, bottom portion 22, and rim portion 23 are circular in top view. The container 2 has an outer diameter φ1, an inner diameter φ2, and a bottom diameter φ3. The outer diameter φ1 corresponds to the diameter of the outer end of the rim portion 23. The inner diameter φ2 corresponds to the diameter of the inner end of the rim portion 23. The bottom diameter φ3 corresponds to the diameter of the bottom portion 22. Furthermore, as shown in Figure 3, the container 2 has a height H.

[0016] As an example, the outer diameter φ1 is 180 mm or more, the inner diameter φ2 is 160 mm or more, the bottom diameter φ3 is 80 mm or more, and the height H is 60 mm or more. (Example 1) φ1: 192mm, φ2: 180mm, φ3: 100mm, H: 86mm (Example 2) φ1: 223mm, φ2: 205mm, φ3: 100mm, H: 95mm (Example 3) φ1: 250mm, φ2: 240mm, φ3: 115mm, H: 110mm It should be noted that various other dimensions can be applied to the container 2 in addition to those exemplified here.

[0017] The handle 3 is, for example, a hollow pipe extending in a long length between a first end 31 and a second end 32. The first end 31 is connected to the container 2. As shown in FIG. 4, a sealing plate 33 is welded to the second end 32. The outer diameter φ4 of the handle 3 is sufficiently smaller than the outer diameter φ1, inner diameter φ2, and bottom diameter φ3 of the container 2. For example, the outer diameter φ4 is 30 mm or less, and in one example, is 25 mm.

[0018] The method for connecting first end 31 and container 2 is not particularly limited, but in one example, welding via a joining plate 4 can be used as shown in Figures 3 and 4. From the perspective of ease of handling of cooking ladle 1, it is preferable that the extension direction of handle 3 is inclined at an acute angle θ with respect to the horizontal plane (a plane parallel to bottom 22), as shown in Figure 3. For example, acute angle θ is 10° or less, and in one example, is 5°.

[0019] The length L of the handle 3 is, for example, 500 mm or more, and in one example, 600 mm. The attachment center of the handle 3 to the container 2 is a distance D from the edge 23. The distance D is, for example, 4 to 6 mm, and in one example, 5 mm. The attachment center corresponds to the intersection of the central axis of the handle 3 and the side 21.

[0020] 5 is a schematic cross-sectional view of edge portion 23. In the example shown in this figure, edge portion 23 has a flat portion 230. Flat portion 230 is connected to the upper end of side portion 21 and is parallel to the horizontal plane (a plane parallel to bottom portion 22).

[0021] Furthermore, the edge 23 has a first portion 231 bent diagonally downward from the flat portion 230, and a second portion 232 that smoothly curves up from the tip of the first portion 231 into the space between the side portion 21 of the container 2 and the first portion 231.

[0022] Providing edge 23 with such a shape can improve the strength of container 2. In addition, in the example of Fig. 5, second portion 232 and side portion 21 are spaced apart from each other. This allows dirt to be easily washed away even if it gets inside edge 23.

[0023] For example, the width Wr of the edge 23 in the radial direction of the container 2 is greater than the width Wz of the edge 23 in the depth direction of the container 2. In one example, the width Wr is 5 mm or more, and the width Wz is 3 mm or less. As a specific example, the width Wr is 6 mm, and the width Wz is 2.5 mm.

[0024] Most of the cooking ladle 1 is made of titanium. Specifically, in this embodiment, the container 2, the handle 3, the sealing plate 33, and the joining plate 4 are all made of pure titanium.

[0025] Conventional cooking ladles are generally made of stainless steel. As a result, the ladles are heavy and difficult to handle, placing a burden on the cook. In particular, in the case of ladles with relatively large containers and handles longer than 500 mm, such as those in Examples 1 to 3 described above, if the entire ladle is made of stainless steel, the burden is extremely large.

[0026] In contrast, the weight of the titanium cooking ladle 1 can be reduced to about half that of a stainless steel ladle of the same shape. As a result, the cooking ladle 1 is easy to handle even for cooks with weak strength, and the burden on them can be significantly reduced.

[0027] Titanium is also stronger than materials such as stainless steel. Therefore, even if the container 2 and handle 3 of the titanium cooking ladle 1 are made thin, they can still achieve strength equal to or greater than that of conventional stainless steel ladle. Furthermore, by making the container 2 and handle 3 thin, the handle 3 is less likely to become hot when scooping hot soup or the like from the container 2.

[0028] When the handle 3 is long, the lighter the container 2 located at the end of the handle 3, the less strain is placed on the user's hand. Therefore, it is preferable that the container 2 be thinner than the handle 3. As an example, the thickness of the container 2 and handle 3 is 1.2 mm or less, preferably 1.0 mm or less. To give more specific numerical values, the container 2 can be 0.5 mm or less, the handle 3 can be 1.0 mm or less, and the sealing plate 33 and joining plate 4 can be 1.2 mm or less.

[0029] As described above, in this embodiment, by using titanium for the container 2 and other components, a thin container 2 can be realized while maintaining strength. However, if the container 2 is as thin as 0.5 mm or less, its edge becomes relatively sharp, posing a risk to the user if the user touches it directly. Furthermore, even if the container 2 is made of titanium, a thickness of 0.5 mm or less may cause distortion. In response to this issue, in this embodiment, as shown in FIG. 5, the edge 23 is curved inward. This prevents the user's fingers from coming into contact with the tip of the edge 23. Furthermore, the strength of the edge 23 is improved, thereby suppressing distortion. Thus, by using titanium for the container 2 and other components and devising the shape of the edge 23, a cooking ladle 1 that is lightweight, strong, and highly safe can be realized.

[0030] In addition to the above, various other advantageous effects can be obtained from this embodiment.

[0031] The configuration of the cooking ladle according to the present invention is not limited to that disclosed in the present embodiment. For example, the specific shapes of the container 2, handle 3, and rim 23, as well as the method of joining the container 2 and handle 3, can be modified in various ways. [Explanation of symbols]
