Description

Technical Field

[0001] This utility model belongs to the field of tableware technology, specifically relating to a ceramic bowl. Background Technology

[0002] In the prior art, bowls that can be stacked and kept warm are generally made of stainless steel. In order to achieve heat preservation after stacking, the outer wall of the bowl is provided with a ring-shaped baffle. The inner side of the ring-shaped baffle is used to connect with the bowl body and has a groove for installing a sealing ring. When two bowls are stacked, the sealing ring can play a sealing role to prevent heat from leaking out and achieve a certain heat preservation effect.

[0003] However, this structure is only easy to process on stainless steel bowls, while ceramic bowls with better heat retention cannot be processed again after molding. Therefore, it is necessary to design a ceramic bowl that also has good heat retention and is easy to demold. Utility Model Content

[0004] This invention addresses the aforementioned problems in the existing technology by proposing a ceramic bowl with good heat retention and easy demolding.

[0005] This utility model can be achieved through the following technical solutions:

[0006] A ceramic bowl, comprising:

[0007] The bowl's body, with its upper rim forming the rim;

[0008] An annular retaining edge is provided on the outer wall of the bowl near the upper edge, and the lower edge of the annular retaining edge is connected to the outer wall of the bowl, forming an angle between them.

[0009] As a further improvement of this utility model, the inner wall of the bowl is provided with an outwardly flared arc-shaped surface at least near the upper edge.

[0010] As a further improvement of this utility model, the closer the arc-shaped surface is to the upper edge of the bowl, the greater the slope at that location.

[0011] As a further improvement of this utility model, the curve length of the arc surface is between 0.5cm and 7cm.

[0012] As a further improvement of this utility model, the upper edge of the bowl body and the annular retaining edge are connected by an arc surface transition.

[0013] As a further improvement of this utility model, the thickness of the annular retaining edge is between 0.1cm and 0.45cm, and the distance between the outermost edge of the lower edge of the annular retaining edge and the bowl body is between 0.1cm and 1cm.

[0014] As a further improvement of this utility model, the wall thickness of the bowl body is between 0.1cm and 0.45cm.

[0015] As a further improvement of this utility model, the inner diameter of the bottom of the bowl is smaller than the inner diameter of its upper edge.

[0016] As a further improvement of this utility model, the bottom of the bowl is provided with a downward-protruding annular protrusion, the height of which is between 0.05cm and 0.4cm.

[0017] As a further improvement of this utility model, the height of the bottom of the bowl located inside the annular protrusion is higher than the height located outside the annular protrusion.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The design of the lower edge of the ring-shaped retaining edge being directly connected to the bowl body makes it easier to demold the ceramic bowl, while also ensuring the stability and good sealing effect after the sealing ring is installed;

[0020] 2. The inner wall of the bowl is designed with an outwardly flared arc surface at least near the top edge. The outwardly flared arc surface can reduce the friction between the bowl and the mold, making the demolding process easier. In particular, when the bowl is removed from the mold, this design can reduce resistance and reduce the risk of damage to the bowl.

[0021] 3. The bottom of the bowl has a downward-protruding ring that provides support when the bowl is placed. The height of the bottom of the bowl inside the ring is higher than that of the bottom outside the ring, making the weight distribution of the bowl more reasonable and allowing it to be placed more stably. Attached Figure Description

[0022] Figure 1 This is a cross-sectional view of the ceramic bowl of this utility model;

[0023] Figure 2 This is a schematic diagram of the structure of the ceramic bowl of this utility model.

[0024] In the diagram, 100 is the bowl body; 110 is the annular retaining edge; 120 is the sealing ring installation area; 130 is the arc-shaped surface; 131 is the position of maximum slope; 132 is the position of minimum slope; 140 is the thickened part; and 150 is the annular protrusion. Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0026] like Figure 1-2 As shown, this utility model provides a ceramic bowl, comprising:

[0027] The bowl body is 100mm, with its upper edge marking the rim.

[0028] An annular baffle 110 is located on the outer wall of the bowl 100 near the upper edge. The lower edge of the annular baffle 110 is connected to the outer wall of the bowl 100, and the two form an angle. At this time, the bottom of the annular baffle 110 forms a sealing ring installation area 120 for installing the sealing ring. Thus, when multiple bowls 100 are stacked, the sealing ring of the upper bowl 100 can abut against the annular baffle 110 of the lower bowl 100. At this time, the upper and lower sides of the sealing ring abut against the annular baffle 110 of the two bowls 100 respectively, which can prevent the heat from leaking out of the lower bowl 100 and achieve the effect of heat preservation.

[0029] Furthermore, since the bowl 100 provided in this embodiment is a ceramic bowl, ceramic has a good heat preservation effect, and the design of the lower edge of the annular baffle 110 being directly connected to the bowl 100 makes it easier to demold the ceramic bowl, while also ensuring the stability and good sealing effect after the sealing ring is installed.

[0030] Preferably, the inner wall of the bowl 100 is provided with an outwardly flared arc surface 130 at least near the upper edge. The outwardly flared arc surface 130 can reduce the friction between the bowl 100 and the mold, making the demolding process easier. Especially when the bowl 100 is removed from the mold, this design can reduce resistance and reduce the risk of damage to the bowl 100.

[0031] In addition, the curved surface 130 design makes the lines of the bowl 100 smoother and more beautiful, improving the product's appearance quality.

[0032] Specifically, the outwardly flared arc-shaped surface 130 refers to the fact that the closer the arc-shaped surface 130 is to the upper edge of the bowl body 100, the greater the slope at that point. This allows for better stress dispersion during demolding, reducing localized stress concentration and thus lowering the risk of cracks or damage to the bowl body 100. For example, in... Figure 1 In the middle, the arc surface 130 has a maximum slope position 131 and a minimum slope position 132. As the arc surface moves from the minimum slope position 132 to the maximum slope position 131, its slope gradually increases.

[0033] Preferably, the curve length of the arc surface 130 is between 0.5cm and 7cm, which maximizes the smoothness of the demolding process.

[0034] Preferably, the thickness of the annular retaining edge 110 is between 0.1cm and 0.45cm, and the distance between the outermost edge of the lower edge of the annular retaining edge 110 and the bowl body 100 is between 0.1cm and 1cm. This design allows the annular retaining edge 110 to have sufficient weight and width. When the two bowl bodies 100 are stacked, the annular retaining edges 110 of the two bowl bodies 100 can ensure the tightness and sealing between themselves and the sealing ring by their own weight.

[0035] Preferably, the wall thickness of the bowl body 100 is between 0.1cm and 0.45cm, which can ensure good heat preservation while ensuring that the bowl body 100 has sufficient structural strength.

[0036] Preferably, the inner diameter of the bottom of the bowl 100 is smaller than the inner diameter of its upper edge.

[0037] Preferably, the bottom of the bowl 100 is provided with a downward-protruding annular protrusion 150, the height of which is between 0.05cm and 0.4cm, which serves as a support when the bowl 100 is placed.

[0038] Preferably, the height of the bottom of the bowl 100 located inside the annular protrusion 150 is higher than the height located outside the annular protrusion 150, which makes the weight distribution of the entire bowl 100 more reasonable and allows it to be placed more stably.

The above are specific embodiments of this utility model.
