Description

Technical Field

[0001] This utility model relates to the field of tableware technology, specifically to a folding container. Background Technology

[0002] Traditional tableware is mostly made by firing, stamping, or injection molding, such as the common porcelain bowls, glass bowls, stainless steel bowls, aluminum bowls, and plastic bowls on the market. These tableware pieces have fixed shapes, and even bowls made of metal or plastic are prone to breakage. Once broken or deformed, they become unusable. Furthermore, the various shapes and sizes of tableware make storage space-consuming and inconvenient.

[0003] Chinese patent CN202619144U discloses a silicone folding bowl. The folding bowl is integrally molded from silicone through injection molding. The bowl wall is composed of alternating protrusions and connecting parts to form a telescopic structure. The connecting part is a groove with a thickness less than that of the protrusions. A detachable bowl rim frame made of a rigid material is movably connected to the edge of the folding bowl.

[0004] The aforementioned existing technology creates grooves by reducing the thickness of the connecting parts to allow the bowl wall to extend and fold. However, this results in an uneven surface on both the inner and outer sides of the bowl wall, leading to insufficient structural stability in practical use. A rigid frame is required at the rim to ensure proper operation, resulting in a poor user experience. Therefore, the existing technology requires further improvement and development. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a foldable container with a reasonable structure, stable folding, and good user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The present invention discloses a folding container, comprising a base and a container wall. The container wall is arranged around the base and is composed of N layers of folded segments arranged sequentially from top to bottom. The diameter of the N layers of folded segments decreases from top to bottom, where N is an odd number and N≥3. Two adjacent layers of folded segments are connected by annular creases located on the inner side of the container wall, and the outer side of the container wall corresponding to the annular creases is a smooth surface. The uppermost folded segment forms the opening of the container wall, and the lowermost folded segment forms the base of the container wall, which is integrally connected to the base.

[0008] According to the above scheme, when N=3, the folded segment includes a first sidewall ring, a second sidewall ring and a third sidewall ring. The first sidewall ring forms the opening of the container wall and the third sidewall ring forms the bottom of the container wall. The second sidewall ring is located between the first sidewall ring and the second sidewall ring, and the first sidewall ring, the second sidewall ring and the third sidewall ring are connected from top to bottom through annular creases.

[0009] According to the above scheme, when N>3, the folded segment includes a first sidewall ring, a second sidewall ring, a third sidewall ring, and a reinforced sidewall ring. The first sidewall ring forms the opening of the container wall, and the third sidewall ring forms the bottom of the container wall. At least two layers of second sidewall rings are provided between the first sidewall ring and the third sidewall ring. The first sidewall ring and the third sidewall ring are respectively connected to the adjacent second sidewall rings through annular creases. A reinforced sidewall ring is provided between two adjacent layers of second sidewall rings. The reinforced sidewall ring and the second sidewall ring are connected through annular creases.

[0010] According to the above scheme, the thickness of the first sidewall ring is L1, the thickness of the second sidewall ring is L2, and the thickness of the third sidewall ring is L3. Therefore, L1 > L2 and L3 > L2.

[0011] According to the above scheme, L1 > L3 > L2.

[0012] According to the above scheme, the thickness of the reinforced sidewall ring is L4, and 1.5×L2≤L4≤2.5×L2.

[0013] According to the above scheme, the diameter of the lower port of the first sidewall ring is S1, and the diameter of the upper port of the third sidewall ring is S3. Then S1-S3≥2×L2.

[0014] According to the above scheme, the outer side of the mouth is provided with a convex lip, which is a ring structure formed by extending the outer wall of the upper end of the first side wall ring outward; an anti-overflow fold is provided between the convex lip and the outer wall of the mouth.

[0015] According to the above scheme, the inner side of the mouth is provided with a lip edge fitting surface, which is a transition curved surface between the upper end surface of the first side wall ring and the inner wall of the mouth, so that the wall thickness of the mouth gradually decreases from bottom to top.

[0016] According to the above scheme, the edge of the base is provided with an extended protrusion, and a gripping groove is formed between the extended protrusion and the outer wall of the third side wall ring; the contour trajectory of the gripping groove on the vertical section is a composite curvature, the composite curvature includes curvature R1 and curvature R2, and R1≤R2.

[0017] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure, the outer surface of the container wall is smooth and not easy to accumulate dirt, the folding sections are connected by annular creases so that the container wall can be folded and has strong support. After food is put in, the pressure applied to the container wall by a person's hand (especially the thumb) will not easily cause the structure to collapse. It has good stability and is convenient to use. Attached Figure Description

[0026] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-6As shown, the folding container of this utility model includes a base 1 and a container wall 2. The container wall 2 is arranged around the base 1 and is composed of N layers of folded segments arranged sequentially from top to bottom. The diameter of the N layers of folded segments decreases from top to bottom, where N is an odd number and N≥3. Adjacent layers of folded segments are connected by annular creases 25 located on the inner side of the container wall 2, with the corresponding outer side of the container wall 2 being a smooth surface. The uppermost folded segment forms the opening 20 of the container wall 2, and the lowermost folded segment forms the base of the container wall 2, which is integrally connected to the base 1. It is understood that this utility model is made entirely of silicone, a material that combines flexibility and plasticity, making the structure of the container wall 2 stable enough to hold food. Specifically, the container wall 2 is composed of multiple folded segments, which can be folded sequentially through the annular creases 25 for easy storage and carrying. Furthermore, the annular crease 25 is provided on the inner side of the container wall 2, making the outer side of the container wall 2 smooth overall, with a better feel and less prone to accumulating dirt.

[0028] Furthermore, the annular crease 25 is located on the inner side of the container wall 2. When liquids or other food are filled in, the internal food compression will cause the crease to expand, stretching the crease and preventing the container wall 2 from collapsing. In particular, the pressure applied by the thumb to the container wall is less likely to cause the container wall 2 to collapse, and the gripping force of the hand can counteract the squeezing force on the inner side of the container wall 2, making the overall structure of the container more stable and providing a better user experience.

[0029] Example 1

[0030] like Figure 1-3 As shown, in this embodiment, N=3. The folded segment includes a first sidewall ring 21, a second sidewall ring 22, and a third sidewall ring 23. The first sidewall ring 21 forms the opening 20 of the container wall 2, and the third sidewall ring 23 forms the bottom portion of the container wall 2. The second sidewall ring 22 is disposed between the first sidewall ring 21 and the second sidewall ring 22, and the first sidewall ring 21, the second sidewall ring 22, and the third sidewall ring 23 are connected sequentially from top to bottom by annular creases 25. In this embodiment, the first sidewall ring 21, the second sidewall ring 22, and the third sidewall ring 23 form the container wall 2, and the first sidewall ring 21, the second sidewall ring 22, and the third sidewall ring 23 can be folded relative to each other through annular creases 25, thereby reducing the overall height and volume.

[0031] The thickness of the first sidewall ring 21 is L1, the thickness of the second sidewall ring 22 is L2, and the thickness of the third sidewall ring 23 is L3, so L1 > L2 and L3 > L2. Specifically, the first sidewall ring 21 serves as the opening 20 of the container wall 2, and the third sidewall ring 23 serves as the bottom part of the container wall 2 connected to the bottom plate 11. Therefore, the first sidewall ring 21 and the third sidewall ring 23 need to have a large thickness to ensure the overall stability and structural strength of the container wall 2, so as to provide sufficient support to realize the holding function.

[0032] It is understood that the folded segments are connected by annular creases 25, which are equivalent to forming annular thinning areas on the container wall 2 to make it foldable. Accordingly, the thickness of the container wall 2 (including the folded segments) will affect the folding performance, that is, each folded segment itself can also be deformed.

[0033] Furthermore, the second sidewall ring 22 is disposed between the first sidewall ring 21 and the third sidewall ring 22. The thickness L2 of the second sidewall ring 22 is smaller, which reduces its strength but enhances its deformation capacity. Consequently, when the container wall 2 is folded, the deformation of the first sidewall ring 21 and the third sidewall ring 22 is smaller, and the deformation of the second sidewall ring 22 allows them to relatively come together (i.e., fold). The smaller thickness of the second sidewall ring 22 allows the container wall 2 to deform, and in conjunction with the annular creases 25 at its upper and lower ends, the folding action of the container wall 2 is made smoother.

[0034] Preferably, the thickness of the first sidewall ring 21 is L1, the thickness of the second sidewall ring 22 is L2, and the thickness of the third sidewall ring 23 is L3, with L1 > L3 > L2. The third sidewall ring 23 is connected to the base 1, and the base 1 can provide structural support, so that L3 can be less than L1, which can also ensure the structural stability of the container wall 2 and reduce the overall material cost.

[0035] The diameter of the lower port of the first sidewall ring 21 is S1, and the diameter of the upper port of the third sidewall ring 23 is S3, so S1-S3≥2×L2. The overall diameter of the container wall 2 gradually decreases from top to bottom. During the folding process, the second sidewall ring 22 will partially overlap, and S1-S3≥2×L2 makes the container wall 2 easier to fold.

[0036] The upper end of the first sidewall ring 21 forms an opening 20, and a lip 201 is provided on the outer side of the opening 20. The lip 201 is an annular structure formed by extending the outer wall of the upper end of the first sidewall ring 21 outward. The lip 201 extends outward from the opening 20, which can improve the strength of the upper opening of the first sidewall ring 21. At the same time, when the user drinks soup, the lip 201 can fit the lower lip to prevent leakage.

[0037] An anti-overflow fold 202 is provided between the convex lip 201 and the outer wall of the mouth 20. As mentioned above, the convex lip 201 extends outward from the mouth 20. The anti-overflow fold 202 is equivalent to establishing a transition plane / curved surface between the convex lip 201 and the first side wall ring 21, which not only ensures that the convex lip 201 can fit the lower lip, but also improves the strength of the convex lip 201 and prevents deformation.

[0038] Furthermore, the inner side of the mouth 20 is provided with a lip-edge fitting surface 203, which is a transitional curved surface between the upper end face of the first sidewall ring 21 and the inner wall of the mouth 20, thereby making the wall thickness of the mouth 20 gradually decrease from bottom to top. When the user uses it, the mouth 20 is located between the upper and lower lips, and the convex lip 201 fits the lower lip to prevent overflow. It can be understood that the lip-edge fitting surface 203 is equivalent to eliminating part of the solid inside the mouth 20 and connecting the convex lip 201 in the contour, so that the wall thickness of the mouth 20 gradually decreases from bottom to top. That is, the lip-edge fitting surface 203 is equivalent to thinning the mouth 20. When the user drinks, the thin-walled area inside the mouth 20 formed by the lip-edge fitting surface 203 can adaptively fit the shape of the lips, reducing the foreign body sensation of hard edges.

[0039] The base 1 has an extended protrusion 11 on its edge, forming a gripping groove 12 between the extended protrusion 11 and the outer wall of the third sidewall ring 23. The contour trajectory of the gripping groove 12 on the vertical section is a composite curvature, which includes curvature R1 and curvature R2, and R1≤R2. Preferably, the extended protrusion 11 firstly increases the bottom area of ​​the base 1, making the overall placement more stable, and also improves the strength of the base 1 and the third sidewall ring 23. Furthermore, the gripping groove 12 is used to establish a continuous transition between the outer side of the container wall 2 and the base 1, improving the consistency of the appearance. Even further, R1 at the extended protrusion 11 is used to contact the hand; the smaller contact surface prevents slippage and makes it convenient for the user to grip the lower end of the bowl, while the larger contact surface at R2 makes the user's grip more comfortable.

[0040] The third sidewall ring 23 is integrally connected to the base 1. Meanwhile, the wall thicknesses L1 and L3 of the first sidewall ring 21 and the third sidewall ring 23 are both greater than the wall thickness L2 of the second sidewall ring 22, making the strength of the first sidewall ring 21 and the third sidewall ring 23 greater than that of the second sidewall ring 22. The container wall 2 can be folded into a fixed shape by striking it up and down with both hands. Figure 3 The state.

[0041] Example 2

[0042] like Figure 4-6As shown, the only difference between this embodiment and Embodiment 1 is that N > 3. The folded segment includes a first sidewall ring 21, a second sidewall ring 22, a third sidewall ring 23, and a reinforced sidewall ring 24. The first sidewall ring 21 forms the opening 20 of the container wall 2, and the third sidewall ring 23 forms the bottom of the container wall 2. At least two layers of second sidewall rings 22 are provided between the first sidewall ring 21 and the third sidewall ring 23. The first sidewall ring 21 and the third sidewall ring 23 are respectively connected to the adjacent second sidewall rings 22 through annular creases 25. A reinforced sidewall ring 24 is provided between two adjacent layers of second sidewall rings 22. The reinforced sidewall ring 24 and the second sidewall ring 22 are connected through annular creases 25.

[0043] When N > 3, the container wall 2 in this embodiment can have 5, 7, 9... folded segments. For ease of understanding, N = 5 is used as an example for specific explanation. The layering and function of the first sidewall ring 21 and the third sidewall ring 23 on the container wall 2 are the same as in Embodiment 1, so they will not be repeated. Among them, two layers of second sidewall rings 22 are provided between the first sidewall ring 21 and the third sidewall ring 23, and a reinforcing sidewall ring 24 is provided between the two layers of second sidewall rings 22. That is, the first sidewall ring 21 and the reinforcing sidewall ring 24 can be folded together through the second sidewall rings 22, and the reinforcing sidewall ring 24 and the third sidewall ring 23 can be folded together through the second sidewall rings 22, thereby folding the container wall 2 with 5 folded segments to reduce the overall height and volume.

[0044] As described above, the thickness of the first sidewall ring 21 is L1, the thickness of the second sidewall ring 22 is L2, and the thickness of the third sidewall ring 23 is L3, so L1 > L2 and L3 > L2. The first sidewall ring 21 serves as the opening 20 of the container wall 2, and the third sidewall ring 23 serves as the bottom part of the container wall 2, connected to the bottom plate 11. Therefore, the first sidewall ring 21 and the third sidewall ring 23 need to have a large thickness to ensure the overall stability and structural strength of the container wall 2, so as to provide sufficient support to realize the holding function.

[0045] It is understood that the folded segments are connected by annular creases 25, which are equivalent to forming annular thinning areas on the container wall 2 to make it foldable. Accordingly, the thickness of the container wall 2 (including the folded segments) will affect the folding performance, that is, each folded segment itself can also be deformed.

[0046] Furthermore, the second sidewall ring 22 is disposed between the first sidewall ring 21 and the third sidewall ring 22. The thickness L2 of the second sidewall ring 22 is smaller, which reduces its strength but enhances its deformation capacity. Consequently, when the container wall 2 is folded, the deformation of the first sidewall ring 21 and the third sidewall ring 22 is smaller, and the deformation of the second sidewall ring 22 allows them to relatively come together (i.e., fold). The smaller thickness of the second sidewall ring 22 allows the container wall 2 to deform, and in conjunction with the annular creases 25 at its upper and lower ends, the folding action of the container wall 2 is made smoother.

[0047] Furthermore, in this embodiment, two layers of second sidewall rings 22 are provided between the first sidewall ring 21 and the third sidewall ring 23, and a reinforced sidewall ring 24 is provided between the two layers of second sidewall rings 22, so that the folding action is smooth, stable and controllable.

[0048] Furthermore, the thickness of the reinforcing sidewall ring 24 is L4, where 1.5×L2≤L4≤2.5×L2. The thickness L4 of the reinforcing sidewall ring 24 falls within the aforementioned range, ensuring both the structural strength of the container wall 2 and the feasibility of folding. The container wall 2 can be folded into its original shape simply by tapping it up and down with both hands. Figure 6 The state.

[0049] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
