Description

Technical Field

[0001] The utility model belongs to the technical field of lunch boxes, and particularly relates to a lunch box in the form of a snap made of corn starch material. Background Art

[0002] A lunch box made of corn starch material is an environmentally friendly lunch box mainly made of a plant-based material, corn starch. Due to its biodegradable characteristics, this lunch box has significant advantages in environmental protection and can effectively reduce environmental pollution. The corn starch material not only has good oil resistance and heat resistance, can safely store various foods, but also can be degraded relatively quickly in the natural environment, making it a more and more popular choice in the takeaway and fast food industries. In the design of a lunch box made of corn starch material, a snap is an important component, mainly used to ensure the tight closure of the lid and the lunch box body. The reason for designing the snap is to make it more convenient and fast to open and close the lunch box, improving the user experience. However, there is often a phenomenon that the snap is not firm in the design of the existing corn starch material lunch boxes. The main reason is that the corn starch material lunch box is prone to slight deformation after being heated, resulting in an insecure snap. The conventional countermeasure is to use higher-quality corn starch materials to improve its toughness and elasticity and enhance the fixing force of the snap. However, the disadvantage of this method is that high-quality materials and optimized designs may lead to an increase in production costs, thus increasing the price of the final product. Therefore, a new structure is proposed to solve the above problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a lunch box in the form of a snap made of corn starch material.

[0004] The utility model is realized through the following technical solutions: A lunch box in the form of a snap made of corn starch material, comprising: a box lid, an adjusting rod, and a clamping groove. A box body is provided below the box lid. A first reinforcing ring is provided below the side surface of the box body, and a second reinforcing ring is provided above the first reinforcing ring;

[0005] A set of connecting bases are respectively provided at the front and rear positions on the right side of the second reinforcing ring. A set of tongue pieces are provided above the two sets of connecting bases. The bottom of each tongue piece is connected to the two sets of connecting bases through hinge columns. An adjusting rod is provided on the left side above each tongue piece;

[0006] A set of sliding grooves are respectively opened inside the front and rear sides of the top of each tongue piece. An adjusting spring is provided on the right side inside each sliding groove. A moving groove is provided through the side of each sliding groove close to the adjusting rod. A set of sliding blocks are respectively provided on the front and rear sides of the adjusting rod. A set of clamping grooves are respectively provided at the front and rear positions on the right side of the top of the box lid.

[0007] As a preferred embodiment, both the first reinforcing ring and the second reinforcing ring are made of stainless steel. The shapes of the first reinforcing ring and the second reinforcing ring both match the shape of the box body, and the top of the second reinforcing ring is fixed to the bottom of the connecting base.

[0008] As a preferred embodiment, the structures on the front and rear sides of the top of the second reinforcing ring are exactly the same and are arranged in mirror symmetry. The structures on the left and right sides of the top of the box cover are exactly the same and are arranged in mirror symmetry. The tongue is an L-shaped structure. In actual use, the first reinforcing ring is sleeved on the lower side of the box body. When the box body undergoes slight deformation, it can reinforce the box body, making the box body structure stable and ensuring the firmness of the box body. The second reinforcing ring is sleeved on the upper side of the box body. On the one hand, it reinforces the upper side of the box body, ensuring the stability of the upper side of the box body. On the other hand, the two connecting bases on the top of the second reinforcing ring are connected to the tongue through two hinge columns, playing a role in supporting the tongue. The final effect is that the first reinforcing ring and the second reinforcing ring can reinforce the side of the box body, increasing the stability of the box body structure.

[0009] As a preferred embodiment, the adjusting rod is fixedly connected to the slider through a connecting rod, and the length, width, and height of the slider match the length, width, and height of the sliding groove.

[0010] As a preferred embodiment, the length of the adjusting rod is greater than the interval length between the two card slots. The card slot is an L-shaped structure, and the height of the card slot is greater than the height of the adjusting rod.

[0011] As a preferred embodiment, the side of the sliding groove away from the slider is fixed to the side of the adjusting spring away from the slider, and the side of the adjusting spring close to the slider is fixedly connected to the slider.

[0012] As a preferred embodiment, both the adjusting rod and the tongue are made of stainless steel. The length of the adjusting rod matches the width of the tongue, and the thickness of the adjusting rod is equal to the thickness of the tongue. During actual use, first, turn the right tongue to the left until it is above the two left slots. Then, pull the adjusting rod to the left, causing the adjusting rod to move to the left. At this time, the two connecting rods move to the left along the two moving slots, simultaneously driving the two sliders to move to the left inside the sliding slots and stretching the two adjusting springs, causing the two adjusting springs to stretch and store energy. Continue to turn the tongue to the left until the bottom of the tongue contacts the top of the lid. Then, release the adjusting rod, allowing the two adjusting springs to rebound freely, and snap the adjusting rod into the two slots. Since the two adjusting springs are always in a stretched state, the adjusting rod is always tightly snapped into the two slots. Even if the lunch box undergoes slight deformation during use, the adjusting spring can ensure that the adjusting rod remains tightly snapped into the slots. Adjust the left tongue according to the above steps to tightly snap the left tongue into the two left slots, thus completing the snapping of the two tongues into the four slots. The final effect is that through the pulling of the two adjusting springs, the two adjusting rods are firmly connected to the four slots.

[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By setting the adjusting rod, the adjusting spring, and the slider, pulling the adjusting rod causes the adjusting rod to move left and right, thereby driving the two sliders to move left and right along the two sliding slots respectively. The adjusting spring is stretched and stores energy under the drive of the slider. Thus, after the adjusting rod is snapped into the two slots, the elastic force of the two adjusting springs causes the adjusting rod to be tightly snapped into the two slots, so that the tongue is firmly snapped into the slot. This not only ensures the tightness of the snap connection but also reduces the production cost. By setting the first reinforcing ring and the second reinforcing ring, the first reinforcing ring reinforces the lower part of the side of the box body, and the second reinforcing ring reinforces the upper part of the side of the box body, thereby reinforcing the entire side of the box body, increasing the stability of the box body, and improving the overall firmness of the lunch box.
