Description

The present invention relates to a ladle for large-scale lunch cooking used for large-scale cooking such as lunch cooking.

The present invention pursues the ease of holding a ladle handle for lunch cooking on the market and the durability of the whole, and has excellent work efficiency without greatly impairing its safety, and has a comfortable use. It relates to ladle.

Lunch cooking utensils are articles that are used in cooking chambers that cook dozens of food at once in large pans, iron plates, etc., and are used for a long period of time in a hot and humid environment and a large amount of food It is.
An article placed under high load conditions.
A cooking utensil used in such a harsh environment is one of the utensils required to develop a product particularly severely in terms of food safety and hygiene, as well as user comfort.

The following literature techniques can be found as related to the present invention.
Japanese Patent Application Laid-Open No. 10-146778 “Tool with Pattern and Pattern Section for Tool with Pattern” JP, 9-164086, A "Tool with a handle" In the above two, it is a tool with a handle which made it possible to remove a container part and a handle part. Considering these and the features of commercial products, we will consider the constituent materials, structural features, and shape features.

First, we will consider the components of conventional products.
Conventional products have been manufactured from various materials such as wood, plastic and metal. Wooden and plastic products are light and easy to handle, but due to long-term use, there is a possibility of damage or melting due to partial strength reduction due to heat or moisture, etc. Some cases have been mixed. At present, such a situation is also received, and there is a tendency in the industry to refrain from using this material product.

On the other hand, metal products have a very strong resistance to such heat and moisture. In particular, stainless steel having excellent rust resistance has no problem even when used for a long period of time. Therefore, it is often used for domestic cooking utensils regardless of business use such as lunch. However, a large-sized meal utensil than that for home use has a disadvantage that the weight is increased and work efficiency cannot be denied.
In addition, compared with wooden and plastic products, metal products have a lower coefficient of friction and are more slippery during work.

Next, the structural features of conventional products will be considered.
As a structural feature of the conventional product, a container part for scooping food and a handle part are directly attached with screws, etc., and a cylindrical wooden handle is inserted into a circular connecting part fixed to the container part. What is attached with a screw etc. and what attached each part by partial welding are known.
A product attached with a screw or the like has a merit that it is simple in structure and does not take time to manufacture, but has a problem that it loosens during use, the screw falls off and mixes into food, and the head falls off. In addition, those using parts such as wooden handles for the connecting part are somewhat complicated in structure, but the overall strength is high, but the ingredients penetrate into the fitting part and become unsanitary. There is a problem that it is necessary to easily remove and clean, and it is inconvenient to attach and remove the screw. Further, when the attachment and removal are repeated, the screw becomes ineffective and easily comes off.

On the other hand, a product with an integrated structure in which each part is welded is welded to each part, so it takes a little time to manufacture, but the durability is outstanding, and parts such as screws are missing and mixed with food Nor. Usually, spot welding or argon welding is performed so that there is no gap, so there is little concern about mixing of food materials into the fitting part, and there is no problem on the satellite side, but the handle part and container part are directly applied. In the case of contact, the contact area that can be contacted is often small, and there is room for improvement in terms of durability.

Next, the shape characteristics of conventional products will be considered.
Regarding the shape of the conventional product, there are various shapes such as the shape of the container portion, the shape of the handle portion, and the like.
In particular, for the handle, there are many cylindrical shapes with a perfect cross-section, but it is easy to hold by hand, but there is no point to support in the direction of rotation around the axis of the handle, and it is in the hand during work. There is a problem that it is difficult to hold at the same position.

The present invention has a high durability to work such as `` boil '', `` fry '', `` bake '', etc. in a hot and humid environment at the time of lunch cooking work, and the possibility of missing parts due to the structure is low. It is an object of the present invention to provide a ladle for lunch cooking that has a strong resistance to the direction of rotation around the axis.

As a concrete issue,
(A) It is made of a material having durability required as a cooking utensil.
(B) Have a safe and hygienic structure that is required as a cooking utensil.
(C) It has characteristics that make it easy to handle as a cooking utensil.
We set out to solve the problem.

In order to solve the above problems, a ladle for lunch cooking of the present invention is a ladle for lunch cooking consisting of a container part 1 or a net (net) part 1, a joint part 2, a handle part 4, and a hanging ring 6 (FIG. 1). ).

(A) In the present invention, all components were manufactured using stainless steel having particularly strong strength and excellent rust resistance among metal materials specialized in heat and water resistance.

(B) In the present invention, in order to eliminate the possibility of missing particularly important parts as cooking utensils, no fine parts such as screws are used, and the container part 1 or the net (net) part 1 and the joining part 2 Only four parts of the handle portion 4 and the hanging ring 6 were adopted, and a ladle having an integral structure in which these were fixed at multiple points by either spot welding, argon welding, plasma welding or a combination thereof was adopted.

(C) In the present invention, in consideration of ease of handling during work, an elliptical column that is easy to adjust to the hand when gripping is adopted for the handle. At this time, the elliptical cylinder is created by pressing a cylinder with a perfect cross section from 15 mm from both ends to the center and pressing both sides with a plate-like object, so that the cross section at both ends of the elliptical cylinder is a perfect circle. Created.
The handle portion was connected to the container portion so that the horizontal angle was 30 degrees.

In the present invention, the overall weight is reduced by making the contents hollow in the handle.
The configurations (a), (b), and (c) correspond to the aforementioned problems (A), (B), and (C), respectively.

  The ladle for lunch cooking of the present invention has the following technical effects by solving the above-mentioned problems.

(A) In the present invention, all components are manufactured using stainless steel specializing in heat resistance, water resistance, and rust resistance. Therefore, the durability is higher than conventional products and the service life is extended. It has become possible. In addition, it is possible to prevent fragments from peeling off due to decay and dissolution, which has occurred in wooden and plastic products. As a result, hygienic problems such as fragment contamination in food materials that have been caused in conventional wooden and plastic products have been solved.

(B) In the present invention, in order to eliminate the possibility of missing parts, no small parts such as screws are used, and only the four parts of the container part 1, the joining part 2, the handle part 4 and the hanging ring 6 are used. By adopting it, we solved the problem of missing fine parts such as conventional fastening screws.
In addition, there are many conventional products in which the container portion and the handle portion are directly welded and those that are directly fastened with screws, but in the present invention, the joining part 2 is provided separately. This drastically increases the weldable area with each part, and because this and the container part 1 and handle part 4 are welded at multiple points, higher durability and strength than conventional products are achieved. .
In addition, since it has an integrated structure as a whole, it is possible to wash the entire body even during cleaning, thereby achieving the standards required for hygiene.

(C) In the present invention, when the handle is gripped from the upper part by making it oval, the pressed surface fits the surface of the palm, realizing higher holding force than the conventional circular product.
At this time, the contact area between the hand and the handle is large, and there is a support for resisting the force to rotate the handle in the axial direction. The nature is low.
The hanging ring adopted at the end of the handle also provides a point to support a part of the hand when grasping, and as a whole, it is easier to hold than conventional products.
In addition, the elliptical column of the handle portion presses the cylinder from about 10 mm from both ends to leave a perfect circle at both ends, thereby realizing easy contact with other parts.

In addition, in the present invention, in order to reduce the weight that becomes a disadvantage in metal cooking utensils, the inside of the handle is made hollow, the overall weight is reduced, and a weight that can be used comfortably even for long hours of work has been realized. .
