[0002] Traditionally, when baking bread, pastries, and other baked goods in an oven, a container with a rectangular shape when viewed from above is used, such as a baking pan (also called a tray). Generally speaking, there are two types of baking pans: Japanese standard baking pans and European standard baking pans, and they are available in a variety of materials and surface finishes.

[0003] Furthermore, since baking pans are reused, a baking pan with high thermal conductivity and lightweight is sought, taking into account factors such as work efficiency and durability.

[0004] Patent Document 1 discloses a baking pan made of aluminum that can bake delicious bread with good browning and elasticity in a short time. In this baking pan, the baking pan is also reinforced by attaching reinforcing materials such as iron bars to the folded-back inner side to prevent deformation caused by impact.

[0005] Patent document 2 discloses a sturdy and non-deformable baking pan for bread baking using steel plates. The purpose of this baking pan is to prevent rust and debris accumulated in the flange from being thrown out, and to prevent deformation such as bending of the flange caused by use, by bending the flange of the baking pan to enclose a reinforcing iron core, and spot welding the front end face of the bend and the side plate of the baking pan in a desired number.

[0010] Problems to be solved by utility models

[0011] As mentioned above, baking pans are designed for repeated use. However, due to repeated use, there is a risk of dirt, rust, and deformation due to years of deterioration caused by the accumulation of baking residue or fine debris, or the introduction of foreign matter. This problem is particularly pronounced near the flange and side panels, posing hygiene concerns.

[0012] The patent document 1 discloses a design to prevent the baking pan from deforming. However, it makes no mention of countermeasures for dirt and rust on the flange portion (reinforced edge).

[0013] The patent document disclosed in Patent Document 2 includes a design to prevent deformation such as bending of the flange portion and the ejection of rust and debris accumulated within the flange. However, the front end face of the flange portion and the side plate of the baking tray are only spot-welded in a few places, posing a risk that accumulated rust and debris may inadvertently scatter.

[0014] This utility model was made in consideration of the above-mentioned circumstances, and its purpose is to provide a bread baking pan and a method for manufacturing the bread baking pan that are sturdy, not easily deformed, prevent foreign objects from entering, and have advantages in hygiene.

[0039] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0040] The bread baking pan (hereinafter referred to as "baking pan") 10 of this embodiment is called a six-cavity baking pan and is composed of the following components: a bottom part 12 that is quadrilateral in plan view, which is obtained by forming a metal substrate (B) into a predetermined shape; a side plate part 14, which is formed by raising the periphery of the bottom part 12; a flange part 16, which is formed in an outward direction on the periphery 14a of the side plate part 14, and its outer periphery 16a is bent to abut against the outer periphery 14b of the side plate part 14; and a metal reinforcing member 18, which is arranged to be located on the outer periphery 14b of the side plate part 14 in a closed state by utilizing the flange part 16 and the outer periphery 14b of the side plate part 14, and is enclosed within the flange part 16.

[0041] The substrate material can be made of metal, such as iron plate, aluminized steel plate, or tin-plated steel plate, but is not limited to these. It goes without saying that other metal substrates can be appropriately changed. In addition, the plate thickness is, for example, 1.0 mm, preferably 0.7 mm to 1.5 mm. However, it is not limited to this.

[0042] In addition, a coating layer 20, for example made of silicone resin or fluororesin, is provided on the surfaces of the bottom part 12, the side plate part 14 and the flange part 16.

[0043] In addition, the bottom part 12 is quadrilateral in shape when viewed from above, with dimensions of 530mm × 380mm.

[0044] The side plate portion 14 is formed to stand approximately vertically relative to the bottom portion 12, and its height (H) is 15mm to 45mm.

[0045] The flange portion 16 is formed on the periphery portion 14a of the side plate portion 14 in an outward direction, and its outer periphery portion 16a is bent into a curled shape in an inward direction. The front end portion 16b of the outer periphery portion 16a abuts against the outer periphery portion 14b of the side plate portion 14. Moreover, the inner side of the curled portion is formed into a hollow structure for the placement of the reinforcing member 18.

[0046] The reinforcing member 18 is, for example, a core rod made of iron, aluminum-plated metal, or tin-plated metal with a maximum diameter of 3 mm to 6 mm. Its cross-sectional shape can be circular, square, or a combination of these shapes. In this embodiment, a pentagonal cross-sectional shape, such as a trapezoidal partial defect, is used to simplify the manufacturing process.

[0047] Regarding the above structure, the manufacturing method of baking pan 10 is described below.

[0048] First, a bottom portion 12, a side plate portion 14 formed by vertically raising the periphery of the bottom portion 12, and a flange portion 16 pointing outward from the periphery 14a of the side plate portion 14 are formed by stamping and deep drawing a metal substrate. (See reference) Figure 4 Step S402 (Figures 5(a) and 5(b)). Here, the metal substrate used in this embodiment is preferably 1 mm to 3 mm larger in size than conventional substrates, i.e., compared to conventional substrates used in manufacturing, for example, six-cavity or eight-cavity baking pans.

[0049] in addition, Figures 5(b) to 9(b) The longitudinal section front view shows the bottom surface in an upward position.

[0050] Next, the useless edge portion in the flange portion 16 is trimmed (refer to step S404, FIG6(a), FIG6(b)).

[0051] Next, the outer peripheral edge 16a of the flange 16 is shaped to stand upright at a predetermined angle, for example, vertically (see step S406, FIG7(a), FIG7(b)).

[0052] Furthermore, the reinforcing member 18 is positioned on the flange portion 16 at the outer periphery 14b of the side plate portion 14. The outer periphery 16a (front end 16b) of the raised flange portion 16 is bent into a coiled shape, abutting against the outer periphery 14b of the side plate portion 14 while containing the reinforcing member 18 (see step S408, Figures 8(a) and 8(b)). Here, the inner diameter of the coiled portion is 6mm to 8mm.

[0053] Finally, the outer peripheral edge 16a (inner side) of the flange 16, which is bent into a curled shape in a manner that abuts against the outer peripheral edge 14b of the side plate portion 14, is processed to make it in surface contact with the reinforcing member 18 (see step S410, FIG9(a), FIG9(b)).

[0054] Furthermore, the coating layer 20 can be applied to the metal substrate beforehand or applied after the final process. In this embodiment, the coating layer 20 is applied to at least one surface of the bottom portion 12 and one surface of the side plate portion 14, but it is not limited to this. Moreover, it goes without saying that the coating layer 20 can be applied to all surfaces, including the flange portion 16.

[0055] The baking pan 10 thus completed has the outer peripheral edge 16a of the flange 16 formed into a curled shape. The outer peripheral edge 16a abuts against the outer peripheral edge 14b of the side plate 14 by means of an inner reinforcing member 18. Therefore, compared with the previous product, the strength is increased, it will not deform due to years of use, and the durability is increased, which is useful in practice.

[0056] Furthermore, since the reinforcing member 18 is disposed in a sealed space, it can reliably prevent the ingress of foreign objects, thus solving many problems caused by the ingress of foreign objects in conventional products where the reinforcing member is not sealed, such as the spread of foreign objects into the food manufacturing production line and corrosion caused by rust, which has advantages in terms of hygiene.

[0057] Generally, baking pans require maintenance after a certain period of time, such as removing burnt residue and correcting warping. In conventional products, because the reinforcing components are not sealed, dirt and rust adhering to or near the reinforcing components cannot be completely removed, posing hygiene and durability issues. However, this problem does not occur with the baking pan 10 of this embodiment, making it extremely effective in practical use.

[0058] Furthermore, the baking tray 10 of this embodiment can be achieved without making significant changes to the conventional baking tray manufacturing process, thus reducing environmental impact and achieving excellent results in terms of productivity, economy, and environment.

[0059] Furthermore, this utility model is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the main idea.
