Description

Technical Field

[0001] This invention relates to the field of cooking utensil technology, and in particular to a pot rim and a pot rim production blank. Background Technology

[0002] Existing composite cookware features a three-layer edging structure. This typically involves cutting away the end of a stainless steel layer and part or all of the corresponding aluminum layer, then bending and covering the cut with the remaining stainless steel. However, this edging structure always creates gaps and protrusions at the edging location. These protrusions affect aesthetics, easily trap dirt, and allow moisture to seep into the gaps, causing the aluminum layer at the edging location to gradually oxidize and rust, resulting in bulges. Summary of the Invention

[0003] The main objective of this invention is to provide a pot edge and a pot edge production blank, which aims to prevent water from entering and oxidizing the pot edge, improve the sealing and waterproof properties of the pot edge, and thus make the cookware more durable.

[0004] To achieve the above objectives, the present invention proposes a pot edge comprising a first layer, a second layer and a third layer stacked sequentially, wherein the second layer is provided with a receiving cavity, and the ends of the first layer adjacent to the receiving cavity and the ends of the third layer adjacent to the receiving cavity approach each other and abut against each other to form a rim structure, and the rim structure is accommodated within the receiving cavity.

[0005] In one embodiment, the edge-binding structure includes:

[0006] A first edge portion is formed by winding the first layer from one end adjacent to the receiving cavity toward the receiving cavity; and

[0007] The second edge portion is formed by bending one end of the third layer adjacent to the receiving cavity toward the receiving cavity; and the second edge portion is fitted to the first edge portion.

[0008] In one embodiment, the second edge portion and the first edge portion are arranged symmetrically vertically within the receiving cavity.

[0009] In one embodiment, the bent end of the first edge portion and the bent end of the second edge portion are arranged in an arc shape.

[0010] In one embodiment, both the first edge portion and the second edge portion are made of stainless steel.

[0011] The present invention also proposes a production blank for the edge of a pot as described above, the production blank comprising a first blank layer, a second blank layer and a third blank layer stacked in sequence, wherein the outer end face of the second blank layer is provided with a groove.

[0012] In one embodiment, the groove is a U-shaped groove.

[0013] In one embodiment, the inner wall surface of the groove is an arc-shaped surface.

[0014] In one embodiment, the first germ layer includes a first bent segment and a first non-bent segment connected in sequence, wherein the thickness of the first non-bent segment is greater than the thickness of the first bent segment;

[0015] And / or, the third germ layer includes a second bent segment and a second non-bent segment connected in sequence, wherein the thickness of the second non-bent segment is greater than the thickness of the second bent segment.

[0016] In one embodiment, the first germ layer and the third germ layer each have a plurality of concave notches on the side opposite to the groove, and the plurality of concave notches are arranged at intervals.

[0017] The pot rim of the present invention comprises a first layer, a second layer, and a third layer stacked sequentially. The second layer has a receiving cavity. The ends of the first layer adjacent to the receiving cavity and the ends of the third layer adjacent to the receiving cavity approach each other to form a rim-covering structure, which is housed within the receiving cavity. With this arrangement, the rim-covering structure formed after abutting against each other is tightly sealed without gaps, and the rim-covering structure is wrapped by the cavity wall, preventing external moisture and dust from entering the rim-covering structure, thereby improving the sealing and waterproofing of the pot rim and making the pot more durable.

[0032] Traditional composite cookware has a three-layer edging structure, with the top and bottom layers made of stainless steel and the middle layer of aluminum. The edging structure typically involves cutting away part or all of the aluminum layer at the end of a stainless steel layer, and then bending and covering the cut edges with the remaining stainless steel layer. However, this edging structure always creates gaps and protrusions at the edging location. These protrusions easily trap dirt, and moisture can easily seep into the gaps, causing the edging structure 14 to gradually oxidize and rust at the edging location, forming bulges.

[0033] Therefore, the present invention proposes a pot edge 10.

[0034] In this embodiment of the invention, reference is made to Figures 1 to 3 The pot edge 10 includes a first layer 11, a second layer 12 and a third layer 13 stacked in sequence. The second layer 12 is provided with a receiving cavity. The ends of the first layer 11 adjacent to the receiving cavity and the ends of the third layer 13 adjacent to the receiving cavity approach each other to form a edging structure 14, and the edging structure 14 is accommodated in the receiving cavity.

[0035] The pot rim 10 is specifically applied to the edge of the pot's rim. The first layer 11, the second layer 12, and the third layer 13 are all made of metal. The first layer 11 is the top layer, and the third layer 13 is the bottom layer. The metal material used in the second layer 12 is less hard than the metal materials used in the first layer 11 and the third layer 13, making it easier to cut and form a receiving cavity in the second layer 12. The end of the first layer 11 adjacent to the receiving cavity is the first end, and the end of the third layer 13 adjacent to the receiving cavity is the second end.

[0036] First, a receiving cavity is cut at one end of the second layer 12 using a cutting device. Then, a bending device is used to push the first end of the first layer 11 closer to the second end of the third layer 13, or to push the second end of the third layer 13 closer to the first end of the first layer 11, so that the first end and the second end move closer to each other until they abut. This abuts the first end and the second end, forming the edging structure 14. Finally, the bending device is used to push the edging structure 14 into the receiving cavity. With this configuration, the edging structure 14 formed after abutting is tightly sealed without gaps, and the edging structure 14 is wrapped by the cavity wall, preventing external moisture and dust from entering the edging structure 14, thereby improving the sealing and waterproofing of the pot edge 10, making the pot more durable.

[0037] In one embodiment, reference is made to Figures 1 to 3 The edge-binding structure 14 includes a first edge-binding portion 141 and a second edge-binding portion 142. The first edge-binding portion 141 is formed by rolling one end of the first layer 11 toward the direction close to the receiving cavity; the second edge-binding portion 142 is formed by bending one end of the third layer 13 toward the direction close to the receiving cavity; and the second edge-binding portion 142 is fitted to the first edge-binding portion 141.

[0038] Specifically, one end of the first layer 11 is pushed towards the receiving cavity using a bending device. Since the first layer 11 is a strip-shaped component, the end of the first layer 11 adjacent to the receiving cavity gradually bends and enters the receiving cavity during the pushing process. The end of the first layer 11 adjacent to the receiving cavity gradually becomes curved during the pushing process until the curved end of the first layer 11 fills half of the receiving cavity. Similarly, one end of the third layer 13 is pushed towards the receiving cavity using a bending device. Since the third layer 13 is a strip-shaped component, the end of the third layer 13 adjacent to the receiving cavity gradually bends and enters the receiving cavity during the pushing process. The end of the third layer 13 adjacent to the receiving cavity gradually becomes curved during the pushing process until the curved end of the third layer 13 fills the other half of the receiving cavity. The ends of the first edge portion 141 and the second edge portion 142 completely fill the receiving cavity. With the ends of the first edge portion 141 and the second edge portion 142 positioned within the cavity wall, the first edge portion 141 and the second edge portion 142 press against each other within the receiving cavity, thereby making the first edge portion 141 and the second edge portion 142 fit more tightly, thus improving the sealing performance of the edge structure 14.

[0039] In one embodiment, reference is made to Figures 1 to 3 The second edge-wrapping portion 142 and the first edge-wrapping portion 141 are arranged symmetrically in the receiving cavity. In this way, the first edge-wrapping portion 141 and the second edge-wrapping portion 142 can be pushed together with the same force during the processing, so that the first edge-wrapping portion 141 and the second edge-wrapping portion 142 abut more evenly. On the one hand, it improves the connection stability of the edge-wrapping structure 14, and on the other hand, it simplifies the processing steps of the edge-wrapping structure 14.

[0040] In another implementation, refer to Figures 1 to 3 The second edge portion 142 and the first edge portion 141 are arranged asymmetrically in the receiving cavity. That is, the first edge portion 141 and the second edge portion 142 are pushed together with different forces during processing, so that one of the first edge portion 141 and the second edge portion 142 is more tightly abutted against the other of the first edge portion 141 and the second edge portion 142, thereby improving the connection stability of the edge structure 14.

[0041] In one embodiment, reference is made to Figures 1 to 3The first edge portion 141 and the second edge portion 142 are both bent at one end and the other end, respectively, in an arc shape. This arrangement means that the bent end of the first edge portion 141 is formed by being pushed forward by the bending device, and the bent end of the second edge portion 142 is also formed by being pushed forward by the bending device. Both ends of the first edge portion 141 and the second edge portion 142 will protrude outside the receiving cavity. Making the bent ends of the first edge portion 141 and the second edge portion 142 arc-shaped serves two purposes: firstly, to prevent scratching the user's fingers, and secondly, to make the edge structure 14 more aesthetically pleasing and complete.

[0042] In another embodiment, one end of the first edge portion 141 and one end of the second edge portion 142 may be bent into a rectangular or trapezoidal shape.

[0043] In one embodiment, reference is made to Figures 1 to 3 Both the first edge banding portion 141 and the second edge banding portion 142 are made of stainless steel. Thus, after the first edge banding portion 141 and the second edge banding portion 142 are pushed forward by the bending device to form the edge banding structure 14, the edge banding structure 14 is not easily deformed, and the first edge banding portion 141 and the second edge banding portion 142 are not easily rusted or corroded after contact with moisture, further improving the stability of the edge banding structure 14.

[0044] The first layer 11 and the third layer 13 are made of stainless steel, while the second layer 12 is made of aluminum. The aluminum second layer 12 has better deformation capacity, making it easier to cut.

[0045] Reference Figure 1 , Figures 4 to 7 The present invention also proposes a production blank 20 for the pot edge 10 as described above. The production blank 20 includes a first blank layer 21, a second blank layer 22 and a third blank layer 23 stacked in sequence. The outer end face of the second blank layer 22 is provided with a groove 22a. The specific structure of the pot edge 10 is as described in the above embodiments. Since the production blank 20 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] Specifically, the production blank 20 adopts a composite layered structure of a first blank layer 21, a second blank layer 22, and a third blank layer 23 stacked sequentially. A groove 22a is cut into one end face of the second blank layer 22. After the groove 22a is cut into the second blank layer 22, the first blank layer 21 and the third blank layer 23 form a strip structure. One end of the first blank layer 21 and one end of the third blank layer 23 are easier to be bent by the bending equipment. After bending, the first blank layer 21 and the third blank layer 23 are pushed into the groove 22a. The groove wall of the groove 22a limits the bending movement path of the first blank layer 21 and the third blank layer 23, making it easier for the first blank layer 21 and the third blank layer 23 to bend into a rolled end. This makes it easier for the ends of the first blank layer 21 and the third blank layer 23 to fill the groove 22a, making the edge-sealing structure 14 of the pot edge 10 more tightly connected and having better sealing performance.

[0047] Furthermore, referring to Figure 1 , Figures 4 to 7 The groove 22a is a U-shaped groove 22a. When processing the blank 20, only one groove 22a is cut on the outer end face of the second layer 12, and the groove 22a is a U-shaped groove 22a. That is, the groove 22a has a larger groove depth than the conventional groove. In this way, the space of the groove 22a is larger, and the space for the first blank layer 21 or the third blank layer 23 to enter the groove 22a is also larger. This results in a larger contact area between the first blank layer 21 and the third blank layer 23, thus making the connection between the first blank layer 21 and the third blank layer 23 tighter.

[0048] Furthermore, referring to Figure 1 , Figures 4 to 7 The inner wall of the groove 22a is an arc-shaped surface. Specifically, the bottom wall of the groove 22a is set as an arc-shaped surface. In this way, when the first preform 21 and the third preform 23 are pushed forward by the bending device, the arc-shaped surface has an inward bending guiding force on the first preform 21 and the third preform 23, making it easier to process the first preform 21 and the third preform 23 into the edge-sealing structure 14.

[0049] Furthermore, the section of the first blank layer 21 that needs to be bent into the groove 22a is designated as the first bending section 211, and the section of the third blank layer 23 that needs to be bent into the groove 22a is designated as the second bending section 231. The side of the first bending section 211 adjacent to the groove 22a and the side of the second bending section 231 adjacent to the groove 22a are also set as arc-shaped surfaces. That is, the side of the first blank layer 21 adjacent to the groove 22a connects with the groove wall of the groove 22a to form an arc-shaped inner wall surface, and the side of the third blank layer 23 adjacent to the groove 22a also connects with the groove wall of the groove 22a to form an arc-shaped inner wall surface. In this way, the first blank layer 21 and the third blank layer 23 have a stronger inward bending guiding force, thereby accelerating the processing speed of the first blank layer 21 and the third blank layer 23.

[0050] In one embodiment, reference is made to Figure 1 , Figures 4 to 7 The first preform 21 includes a first bent segment 211 and a first non-bent segment 212 connected in sequence, the thickness of the first non-bent segment 212 being greater than the thickness of the first bent segment 211; and / or, the third preform 23 includes a second bent segment 231 and a second non-bent segment 232 connected in sequence, the thickness of the second non-bent segment 232 being greater than the thickness of the second bent segment 231. Thus, through the above arrangement, the first bent segment 211 and the second bent segment 231 are made thinner and lighter, reducing the bending force required for the first bent segment 211 and the second bent segment 231, thereby making the first bent segment 211 and the second bent segment 231 easier to bend, thereby accelerating the processing speed of the first preform 21 and the third preform 23.

[0051] Furthermore, the length of the first bending segment 211 is greater than the sum of the thicknesses of the first preform layer 21, the second preform layer 22, and the third preform layer 23, and the length of the second bending segment 231 is greater than the sum of the thicknesses of the first preform layer 21, the second preform layer 22, and the third preform layer 23. Thus, when the first bending segment 211 and the second bending segment 231 are bent by the bending device, the entire first bending segment 211 and the second bending segment 231 can be bent and rolled into the groove 22a, thereby ensuring the integrity of the edging structure 14 and making the edging structure 14 stronger and less prone to deformation within the groove 22a.

[0052] In one embodiment, reference is made to Figures 4 to 7 The first embryo layer 21 and the third embryo layer 23 each have multiple concave notches on the side opposite to the groove 22a, and the multiple concave notches are arranged at intervals.

[0053] Specifically, multiple concave notches are provided on one side of the first bending segment 211 adjacent to the groove 22a and on one side of the second bending segment 231 adjacent to the groove 22a, thereby further reducing the thickness of the first bending segment 211 and the second bending segment 231, making the first bending segment 211 and the second bending segment 231 easier to bend.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
