Description

Technical Field

[0001] This utility model relates to the field of lunch box technology, and more specifically, to a glass lunch box with a metal lid. Background Technology

[0002] Lunch boxes, as a traditional utensil for holding, storing, and carrying food, are widely used in daily life, schools, offices, food delivery, and outdoor activities. With the development of the social economy, changes in people's lifestyles, and the enhancement of environmental awareness, the functional requirements and material selection of lunch boxes have also evolved from simple to diverse, and from practical to environmentally friendly.

[0003] Existing glass lunch box products, such as food storage glass lunch boxes, microwave-safe glass lunch boxes, and storage glass lunch boxes, almost all have plastic lids with silicone lining. They are fastened to the glass lunch box with clips. However, plastic lunch box lids are relatively weak, especially in winter when they harden and become brittle. They are prone to breakage at the joints during frequent use. Furthermore, the quality of plastic materials varies greatly. Better quality ones meet food-grade standards, while poor quality ones may leach harmful substances during long-term use, affecting human health. Some customers who are sensitive to smells may also find the smell of plastic lunch box lids unacceptable.

[0004] In view of this, we have studied and improved upon the existing problems to provide a glass lunch box with a metal lid. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 5 This utility model provides a specific technical implementation scheme for a glass lunch box with a metal lid:

[0027] A glass lunchbox with a metal lid includes: a lunchbox body 1, a slot 101, a lunchbox lid 2, a lid body 21, a receiving groove 201, a rolled edge 22, a sealing ring 3, a pivot 4, a buckle 5, a hook plate 51, a buckle plate 52, and a locking plate 53.

[0028] The main body of the lunchbox 1 is made of glass, and a slot 101 is provided on the bottom side of the main body of the lunchbox 1 for fixing the lunchbox lid 2.

[0029] The lunch box lid 2 is made of food-grade stainless steel, which has advantages such as high structural strength, excellent high temperature resistance, and strong corrosion resistance, and will not produce odor. The lunch box lid 2 includes a lid body 21 and a rolled edge 22. The lid body 21 is fastened to the top side of the lunch box body 1. The rolled edge 22 is set at the edge of the lid body 21 and is bent towards the lunch box body 1. The edge of the lid body 21 is designed to prevent scratching hands.

[0030] The sealing ring 3 is placed between the lunch box lid 2 and the lunch box body 1 to provide a seal and enhance the overall sealing performance.

[0031] Specifically, the cover 21 is provided with a groove 201, and the sealing ring 3 is provided in the groove 201. The bottom of the sealing ring 3 abuts against the rolled edge 22, and the rolled edge 22 supports the sealing ring 3 to prevent the sealing ring 3 from falling off.

[0032] The rotating shaft 4 is fixedly installed on the top side of the cover 21. The rotating shaft 4 is made of food-grade stainless steel. The two are connected by laser welding. In order to ensure the firmness of the two, the rotating shaft 4 is provided at one point around the cover 21. One end of the buckle 5 is rotatably installed on the rotating shaft 4, and the other end of the buckle 5 is engaged with the lunch box body 1.

[0033] Buckle 5 is made of food-grade plastic and has high structural strength.

[0034] Specifically, the buckle 5 is capable of withstanding high tensile force and includes a hook plate 51, a buckle plate 52, and a locking plate 53. One end of the hook plate 51 is rotatably mounted on the rotating shaft 4; the buckle plate 52 is fixedly mounted on the other end of the hook plate 51; and the locking plate 53 is fixedly mounted on the buckle plate 52. The locking plate 53 engages with the locking groove 101, and the perpendicular line from the axis of the rotating shaft 4 to the perpendicular line from the center of the locking groove 101 is on the same plane. After the locking plate 53 engages with the locking groove 101, it has strong firmness and stability, is not easy to detach, has good tightening effect, and good compatibility.

[0035] Specific implementation steps:

[0036] When in use, pull the buckle plate 52 outward to rotate the hook plate 51, so that the buckle 53 disengages from the slot 101. Then remove the lunch box lid 2, put the food into the lunch box body 1, and after placing the food, put the lunch box lid 2 on the lunch box body 1 and press down the buckle plate 52 so that the buckle plate 53 engages with the slot 101 to complete the seal.

[0037] In summary, this metal-lid glass lunchbox, with both the lid and the hinge made of food-grade stainless steel, boasts advantages such as high structural strength, excellent high-temperature resistance, and strong corrosion resistance, while also being odorless. The rolled edge, located at the edge of the lid and curved towards the main body of the lunchbox, prevents scratching hands and facilitates the fixing of the sealing ring. Furthermore, the bottom side of the lunchbox body features a slot with a locking plate that engages with it. The perpendicular line from the hinge axis to the perpendicular line from the center of the slot lies on the same plane, ensuring strong and stable engagement, preventing detachment, providing good tension, and offering good compatibility. This improvement in the metal-lid glass lunchbox design results in a rationally designed lunchbox with a high-strength, high-temperature-resistant, and corrosion-resistant metal lid, effectively addressing the problems and shortcomings of existing technologies and equipment.
