Description

Technical Field

[0001] This utility model relates to the field of bowls, specifically to a silicone bowl. Background Technology

[0002] Currently, there is a type of metal bowl on the market where the sidewalls extend upwards from the bottom edge to form a closed rim, with the ends of the sidewalls curling outwards to form a rolled edge that fits snugly against the bowl's surface. This type of metal bowl with a rolled edge is more aesthetically pleasing than ordinary metal bowls without one. Based on this type of bowl, a silicone bowl can be made by using a molding process to coat the outer wall and the entire bottom wall of the bowl with a non-slip, impact-resistant silicone layer. During the molding process, solid silicone material melts into a viscous flow state, gradually flowing from the bottom wall of the metal bowl to the outer wall. After the viscous flow solidifies, it shrinks and coats the metal bowl to form a silicone layer. Because the molding mold is under high pressure, after the silicone layer is formed, flash will inevitably form at the parting line of the mold, requiring manual removal after demolding. To avoid damaging the outer surface of the silicone layer and affecting its appearance when removing flash, the parting line (adjusting the parting line is a common technique in the mold making industry) is consciously set at the edge of the silicone layer during the molding process. In this way, the flash will be concentrated along the edge of the silicone layer and form outward from the edge of the silicone layer. After demolding, the flash can be removed by simply cutting around the edge of the silicone layer without damaging the outer surface of the silicone layer. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a silicone bowl that requires less manual removal of burrs, or even no manual removal of burrs at all, and has higher production efficiency.

[0004] To solve the above problems, this utility model provides a silicone bowl, wherein the bowl body forms a side wall from the bottom edge upwards, the end of the side wall is rolled outwards to form a rolled edge, the outer side wall of the bowl body is covered with a silicone layer, and a gap is left between the rolled edge and the end of the side wall for the edge of the silicone layer to be filled and accommodated.

[0005] Furthermore, the top of the bowl sidewall is folded outward radially to form a flange, and the outermost end of the flange is the end.

[0006] Furthermore, the flanged part is horizontal.

[0007] Furthermore, the beginning of the silicone layer covers the bottom wall of the bowl, and the end of the silicone layer extends along the outer wall of the bowl to the notch, hidden between the rolled edge and the end of the bowl's side wall.

[0008] Furthermore, the end of the silicone layer specifically extends sequentially along the outer wall of the bowl and the lower side wall of the flange to the notch.

[0009] Furthermore, the beginning of the silicone layer covers the entire outer bottom wall of the bowl.

[0010] Furthermore, the bottom of the silicone layer is provided with a downward-facing suction cup.

[0011] Furthermore, the bottom of the silicone layer extends downwards in a partial manner to form the suction cup.

[0012] Furthermore, there are three suction cups, arranged at intervals around the vertical axis of the bowl.

[0013] Beneficial effects: The silicone bowl provided by this utility model has a gap between the rolled edge and the end of the bowl side wall. The burrs on the edge of the silicone layer can be filled into the gap and accommodated, and are not easily exposed outside the bowl. As with the prior art, there are fewer burrs that need to be manually removed, or even no burrs need to be manually removed, resulting in higher production efficiency. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments.

[0024] See Figure 2 , Figure 3 and Figure 4 The silicone bowl body 1 forms a bowl sidewall 11 from the bottom edge upwards. The top 111 of the bowl sidewall 11 forms the bowl rim, and folds radially outwards to form a horizontal flange 12. The outermost end of the flange 12 is the end 112 of the bowl sidewall 11, which curls outwards and downwards to form a rolled edge 13. The rolled edge 13 is not tightly attached to the end 112 of the bowl sidewall 11, but leaves a gap 14. See Figure 1 A silicone layer 2 is wrapped around the outside of the silicone bowl body 1, and the beginning 21 of the silicone layer 2 is shown. Figure 7 The silicone layer 2 covers the entire outer bottom wall 15 of the bowl body 1, with three suction cups 23 extending downwards from the bottom, arranged at intervals around the vertical axis of the bowl body 1; the end 22 of the silicone layer 2 is shown in the figure. Figure 4 and Figure 5 It extends sequentially along the outer side wall 113 of the bowl body 1 and the lower side wall of the flanged edge 12 to the notch 14, and is hidden between the rolled edge 13 and the end 112 of the bowl side wall 11.

[0025] The silicone layer 2 is applied to the bowl 1 using a compression molding process. During compression molding, the solid silicone material inside the mold cavity (not shown in the figure) melts and becomes a viscous flow, gradually flowing from the bottom wall 15 of the bowl 1 to the outer wall 113. After the viscous flow silicone material solidifies, it shrinks and covers the bowl 1 to form the silicone layer 2. Because the mold cavity is under high pressure during compression molding, flash will inevitably form at the parting line of the mold corresponding to the silicone layer 2 after molding. In this embodiment, the parting line of the mold is designed to be located at the notch 14 of the bowl 1 (designing the parting line position is a conventional technique in the mold field). This way, the flash will be concentrated along the end 22 of the silicone layer 2, radially outward from the edge of the end 22, and filled into the notch 14, making it less likely to be exposed outside the bowl 1. Therefore, as in the prior art, there is less flash that needs to be manually removed, or even no flash removal at all, resulting in higher production efficiency. In other embodiments, the parting line of the mold can be relocated to... Figure 6 At the X position of the dotted line, in this case, most of the flash will still be filled into the notch 14, but a small part will be at the parting line. Figure 6 The dotted line (X) is formed, and these are at the parting line ( Figure 6 The burr formed by the dotted line X) is covered by the outer rolled edge 13 and is not easily exposed (it will not affect the appearance of the silicone bowl), so it does not need to be removed manually. Since the burr formed by the silicone layer 2 is filled into the notch 14, some of the burr will stick tightly to the inner wall of the notch 14. There is friction between these burrs and the inner wall, and the burrs are not easy to come out of the notch 14. Therefore, the silicone layer 2 is not easy to fall off the bowl body 1.

[0026] In this embodiment, the top end 111 of the bowl sidewall 11 is radially folded outward to form a horizontal flange 12. The outermost end of the flange 12 is the end 112 of the bowl sidewall 11, which is rolled outward and downward to form a rolled edge 13. In other embodiments, the flange 12 can be changed to be inclined upward, inclined downward, or arc-shaped. In fact, the flange 12 can be omitted, and the top end 111 of the bowl sidewall 11 can be used as the end 112 of the bowl sidewall 11 to directly roll outward to form the rolled edge 13.

[0027] In this embodiment, the entire outer wall 113 of the bowl body 1 is covered with a silicone layer 2, and the entire outer bottom wall 15 is also covered with a silicone layer 2. In other embodiments, the silicone layer 2 may be changed to cover only part of the outer bottom wall 15.

[0028] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
