Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-temperature resistant PET food box technology, and in particular to a high-temperature resistant PET food box that is easy to seal. Background Technology
[0002] PET (polyethylene terephthalate) is widely used in food packaging due to its lightweight, transparency, and recyclability. However, ordinary PET has poor heat resistance (around 70°C), while high-temperature resistant PET food boxes, through material modification or structural optimization, can withstand higher temperatures (100~120°C) and are suitable for microwave heating, cooking, and other applications.
[0003] A utility model patent with patent authorization announcement number CN219858081U discloses a high-temperature resistant and heat-proof food packaging box, including a packaging box body and a lid, with the lid positioned on top of the packaging box body. It incorporates an inner cavity and a first heat-insulating cotton installed at the bottom of the inner cavity.
[0004] However, existing high-temperature resistant and easy-to-seal PET food boxes also have certain shortcomings. Most existing high-temperature resistant and easy-to-seal PET food boxes use elastic buckles to seal the lid and the box body. Due to the thinness of the end face of the elastic buckle and the limitations of its own material, it is prone to elastic fatigue after long-term use, resulting in the breakage of the elastic buckle and poor durability. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature resistant and easy-to-seal PET food box.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature resistant and easy-to-seal PET food box includes a PET food box body, an insulation sheet one fixedly connected to the inner wall of the PET food box body, an insulation board fixedly connected to the lower end of the insulation sheet one, the insulation board being in contact with the PET food box body, an insulation sheet two fixedly connected to the inner wall of the PET food box body, an insulation shell fixedly connected to the inner wall of the insulation sheet two, and a partition fixedly connected to the inner wall of the insulation shell. The outer side of the PET food box body is fixedly fitted with an edge one. The upper end of the PET food box body contacts the PET food box lid, which contacts the insulation shell. The outer side of the PET food box lid is fixedly fitted with an edge two, which contacts edge one. The lower end of the PET food box lid is fixedly connected with an insert rod, which is slidably connected to the PET food box body. A locking hole is provided on the side of the insert rod. An elastic locking ball is fixedly connected to the inner wall of the PET food box body, and the elastic locking ball is slidably connected to the locking hole. Through the combined use of the insert rod, locking hole, elastic locking ball, and other structures, the PET food box lid can be limited in position, ensuring that the PET food box lid is in a stable sealing state.
[0007] In addition, a preferred structure is that handles are fixedly connected to both the left and right ends of the PET food box body. The handles are made of silicone. The handles facilitate the use of the PET food box, avoid the problem of burns, and the silicone material has a good feel when used.
[0008] Furthermore, the preferred structure is that the first insulation sheet is rectangular in shape, and the second insulation sheet is U-shaped. Both the first and second insulation sheets are made of insulating foam material. By using insulating foam material, the first and second insulation sheets can have good insulation properties.
[0009] In addition, a preferred structure is that a sealing strip is fixedly connected to the lower end of the second edge, and the sealing strip is slidably connected to the first edge. By setting the sealing strip, the second edge can be sealed.
[0010] Furthermore, in a preferred configuration, two insert rods are provided, symmetrically distributed on the PET food box lid. The insert rods can be used to restrict and limit the position of the PET food box lid.
[0011] In addition, a preferred structure is that the lower end of the insert is provided with a rounded corner, which contacts the PET food box body. The rounded corner allows the elastic ball to be squeezed.
[0012] The beneficial effects of this utility model are as follows: by pushing the PET food box lid into contact with the PET food box body, the sealing strip is submerged in the edge, thus ensuring the sealing performance of the PET food box. It also allows the insert rod to be inserted into the PET food box body. Under the snapping action of the snap hole, elastic snap ball and other structures, the PET food box lid is stable, which facilitates quick sealing and use by operators and ensures the durability of the sealing. This avoids the problems of easy breakage and poor durability caused by plastic buckles in the prior art. Attached Figure Description
