Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to a foldable triangular rice ball making mold. Background Technology

[0002] Triangular rice balls, a common portable food, are typically shaped using specialized molds to ensure a uniform shape. Traditional molds are mostly made of hard plastic and have a fixed triangular pyramidal structure, consisting of a top cover, a lower mold, and a pressing rod, among other parts. Rice is placed into the mold cavity and pressed to form the shape. While these molds are structurally stable and suitable for home or restaurant settings, their overall rigid design results in a large size, making them inconvenient to store and carry. Furthermore, some structural features present challenges such as difficulty in demolding and cleaning, failing to meet modern consumers' demands for portability and ease of use.

[0003] Existing triangular rice ball molds are mostly rigid, one-piece structures with a thickness of 20–35 mm. They are not foldable and take up a lot of storage and carrying space, which is not conducive to applications in portable scenarios such as outdoor use and bento boxes. The molds use upper and lower molds or pressing rods for demolding. After the rice ball is formed, it needs to be ejected or knocked to demold. During the operation, the integrity of the rice ball's shape is easily affected. Some structures have grooves and ribs for positioning. After use, there is a lot of rice residue. Cleaning requires the use of a brush, making maintenance cumbersome. Utility Model Content

[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0016] Example Reference Figures 1-3 This is an embodiment of the present invention, which provides a foldable triangular rice ball making mold, comprising: The folding mechanism 100 is composed of a first folding plate 101, a second folding plate 102, and a third folding plate 103 connected in sequence. The first folding plate 101 and the second folding plate 102 are connected by a first crease area 104, and the second folding plate 102 and the third folding plate 103 are connected by a second crease area 105. The free end of the first folding plate 101 is provided with a locking block 106, and the free end of the third folding plate 103 is provided with a locking groove 107 that cooperates with the locking block 106. The locking block 106 can be embedded in the locking groove 107 and locked and fixed by a buckle 108.

[0017] Specifically, the first crease area 104 and the second crease area 105 are thin-walled hinge structures pre-set on the flexible material, which have elastic deformation capabilities.

[0018] The first crease area 104 and the second crease area 105 are pre-designed thin-walled hinge structures on flexible materials, which have elastic deformation capabilities and can maintain structural integrity during repeated folding and unfolding, and are not prone to fatigue fracture. The crease area is formed on silicone or TPU material through a mold forming process, with a thickness less than the main body thickness of the adjacent folding plates, thereby achieving smooth and stable folding action, ensuring that each folding plate can be bent at an angle of 90° to 120° along the crease area, and finally forming a stable regular triangular pyramid rice ball forming cavity.

[0019] Furthermore, the first folding plate 101, the second folding plate 102, and the third folding plate 103 are the same size and are all rectangular plate structures, with their length and width ratios adapted to the shape of a standard triangular rice ball.

[0020] The first folding plate 101, the second folding plate 102, and the third folding plate 103 are all the same size and are rectangular plate structures. Their length and width ratios are adapted to the shape of standard triangular rice balls. The preferred length is 80-120mm and the width is 60-90mm, which can meet the forming requirements of common triangular rice balls. The surface of each folding plate is flat and smooth, without grooves or ribs, to avoid rice residue and facilitate cleaning. At the same time, it can evenly transmit pressure during the compaction process to ensure that the rice balls have consistent density and distinct edges.

[0021] Preferably, the card block 106 is a semi-circular or trapezoidal protrusion structure, which is set on the outer edge of the first folding plate 101, and the card slot 107 is a through hole that matches the shape of the card block 106, located at the corresponding edge of the third folding plate 103.

[0022] The card block 106 is a semi-circular or trapezoidal protrusion structure, which is set on the outer edge of the first folding plate 101. The card slot 107 is a through hole that matches the shape of the card block 106 and is located at the corresponding edge of the third folding plate 103. After the mold is folded and formed, the card block 106 is inserted into the card slot 107 to achieve position alignment and initial fixation, prevent misalignment and sliding during the pressing and forming process, and improve the convenience of operation and the accuracy of rice ball forming.

[0023] It should be noted that the buckle 108 is an auxiliary locking structure set in the mating area of ​​the buckle block 106 and the buckle slot 107, and adopts an elastic snap-fit ​​method to achieve detachable fixation.

[0024] The buckle 108 is an auxiliary locking structure located in the mating area between the card block 106 and the card slot 107. It adopts an elastic snap-fit ​​method to achieve detachable fixation. The buckle 108 can be a micro snap-fit, an elastic arm structure, or an interference fit design. It automatically locks when the card block is embedded in the card slot and can be unlocked by gently prying it with a finger. The operation is simple and reliable. This buckle structure ensures that the mold remains in a stable closed state when compacting rice, and avoids accidental loosening due to external force.

[0025] In use, the user first folds the folding mechanism 100 along the first crease area 104 and the second crease area 105. These crease areas are pre-set thin-walled hinge structures on flexible materials, possessing elastic deformation capabilities. They can maintain structural integrity and are not prone to fatigue fracture during repeated folding and unfolding. Through a molding process, the locally thinned areas formed on the silicone or TPU material are made thinner than the main body thickness of the adjacent folding plates, thereby achieving smooth and stable folding action. This ensures that each folding plate can be bent at an angle of 90° to 120° along the crease area, ultimately forming a stable regular triangular pyramid-shaped rice ball. The forming cavity contains three identical rectangular plate structures: the first folding plate 101, the second folding plate 102, and the third folding plate 103. Their length-to-width ratio is adapted to the standard triangular rice ball shape, preferably with a length of 80-120mm and a width of 60-90mm, meeting the forming requirements of common triangular rice balls. These folding plates have smooth, flat surfaces without grooves or ribs to prevent rice residue and facilitate cleaning. They also ensure even pressure distribution during compaction, guaranteeing consistent rice ball density and sharp edges. When users prepare to make rice balls, they need to insert the clamp 106, a semi-circular or trapezoidal protrusion structure. The block is placed on the outer edge of the first folding plate 101 and inserted into the corresponding slot 107 located on the edge of the third folding plate 103. This slot is a through hole that matches the shape of the block. After the mold is folded and formed, the block is inserted into the slot to achieve position alignment and initial fixation, preventing misalignment and slippage during the pressing and forming process, thus improving operational convenience and rice ball forming accuracy. Subsequently, the buckle 108 serves as an auxiliary locking structure, using an elastic snap-fit ​​method to achieve detachable fixation. This buckle can be a micro-buckle, an elastic arm structure, or an interference fit design. It automatically locks when the block is inserted into the slot and can be easily unlocked by gently prying it with a finger, making operation simple. Reliable, the snap-fit ​​structure ensures that the mold remains stably closed when compacting rice, preventing accidental loosening due to external force. After completing the above steps, the user only needs to put an appropriate amount of rice into the formed regular triangular pyramid rice ball forming cavity, gently press it with the palm of the hand to ensure good rice ball forming quality, and then unfasten the snap-fit ​​108 to unfold the mold, easily completing the rice ball demolding process and obtaining a regular-shaped triangular rice ball with clear edges. The whole process is not only simple and convenient to operate, but also greatly facilitates the user experience due to the special design of the mold, and solves the problems of large size, inconvenience in carrying and difficulty in cleaning existing technologies.

[0026] In summary, by adopting a flexible and foldable structural design, the triangular rice ball mold can be conveniently converted between shaping and flat storage, significantly reducing storage volume, making it easy to carry and transport, and suitable for outdoor and bento scenarios. The first folding plate 101, the second folding plate 102, and the third folding plate 103 are connected by the first fold area 104 and the second fold area 105, and locked by the locking block 106, the slot 107, and the buckle 108, achieving rapid shaping and stable pressing. When demolding, simply loosen the buckle 108 and unfold the mold, and the rice ball can be completely removed, effectively maintaining sharp edges and avoiding rice residue. Cleaning is simple; it can be cleaned by rinsing with water, improving hygiene and user experience.
