Description

Technical Field

[0001] The utility model relates to a fresh-keeping box for daily life, in particular to an improved technology for the cover structure of a glass fresh-keeping box. Background Art

[0002] Glass fresh-keeping boxes are commonly used daily necessities. Some of them are also very heat-resistant and can be used in microwave ovens and refrigerators. The surface of glass fresh-keeping boxes is smooth without burrs, shiny and beautiful. Suitable for low and high temperatures.

[0003] The existing glass fresh-keeping box lid is made of glass or plastic, which is relatively hard. When the items are high or hard and the height exceeds the upper surface of the glass fresh-keeping box body, the lid cannot be closed tightly, the ear buckles of the lid cannot be buckled, and the fresh-keeping box cannot be sealed.

[0004] CN216165748U discloses a glass lunch box which is drip-free and easy to clean. The patented cover is connected with connecting shafts on all sides, and the connecting shafts are movably connected with buckles. A silicone top is fixedly installed on the bottom surface of the cover, and a sealing ring is bonded to the outer side of the silicone top. By setting an arc-shaped silicone top, condensation in the box can flow down to both sides along the silicone top. The seamless connection between the silicone top and the sealing ring can effectively avoid the phenomenon of food residues getting stuck, and there is no difficult-to-clean position during cleaning.

[0005] The silicone top of the above patent is arranged in the flat cover body. When the items on the upper surface of the box body are arranged in the cover body, the cover cannot be closed. Summary of the invention

[0006] The utility model provides a glass fresh-keeping box with a silicone surface, which solves the problem that when the items in the existing glass fresh-keeping box are higher than the upper surface of the glass fresh-keeping box body, the lid cannot be tightly closed, the ear buckles of the lid cannot be fastened, and the fresh-keeping box cannot be sealed.

[0007] To solve the above problems, the utility model adopts the following technical solutions: a silicone-surface glass fresh-keeping box, comprising a glass box body 1 and a lid frame 2, the lid frame 2 being a frame-shaped structure, and a hollow structure 21 being provided in the middle of the lid frame 2; further comprising a silicone pad 3, the silicone pad 3 being arranged below the lid frame 2 and covering the hollow structure 21 of the lid frame 2, the periphery of the silicone pad 3 being fitted to the lower surface of the lid frame 2, a protrusion 31 being arranged above the silicone pad 3, and the protrusion 31 surrounding the periphery of the silicone pad 3; an annular recess 22 being arranged below the lid frame 2, the protrusion 31 being embedded in the recess 22 to connect the silicone pad 3 and the lid frame 2 together.

[0008] Furthermore, the silicone-surface glass fresh-keeping box of the utility model has the following characteristics: the edge of the silicone pad 3 is pressed tightly between the outer frame 2 of the box cover and the upper edge of the glass box body 1 to seal the fresh-keeping box.

[0009] Advantages of this utility model:

[0010] 1. A silicone pad is used to cover the hollow structure of the outer frame of the box lid to form a soft cover surface. The soft cover surface can be pushed upward to increase the product volume. When the glass box is loaded higher than the upper surface of the glass fresh-keeping box body, the elastic silicone pad is pushed up and the ear buckles of the box lid can be fastened to achieve the sealing of the box lid.

[0011] 2. The soft cover can also be pressed down to expel the air. When the lid is closed tightly, the container can be in a vacuum, which increases the shelf life of food.

[0012] 3. Press the edge of the silicone pad between the outer frame of the box lid and the upper edge of the glass box body to ensure the sealing of the fresh-keeping box.

[0013] 4. Because the edge of the silicone pad is pressed between the outer frame of the box cover and the upper edge of the glass box body, even when there are many items in the box and the pressure on the silicone pad is high, the silicone pad will not separate from the outer frame of the box cover, ensuring sealing.

[0014] 5. The overall structure is simple and easy to use. The silicone pad has multiple functions such as sealing, increasing the height of items, and achieving vacuum. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is described in detail with reference to the best embodiment below.

[0027] like Figure 1-10 As shown, a silicone surface glass fresh-keeping box includes a glass box body 1 and a lid frame 2, wherein ear buckles are respectively arranged on the four sides of the lid frame 2, and the ear buckles fasten the lid frame 2 to the opening position on the glass box body 1; the lid frame 2 is a frame-shaped structure, and the middle part of the lid frame 2 is a hollow structure 21; it also includes a silicone pad 3, which is arranged below the lid frame 2 and covers the hollow structure 21 of the lid frame 2, and the periphery of the silicone pad 3 is attached to the lower surface of the lid frame 2, and a protrusion 31 is arranged above the silicone pad 3, and the protrusion 31 surrounds the periphery of the silicone pad 3; an annular concave channel 22 is arranged below the lid frame 2, and the protrusion 31 is embedded in the concave channel 22 to connect the silicone pad 3 and the lid frame 2 together. When the lid frame 2 is fastened to the opening position of the glass box body 1, the edge of the silicone pad 3 is pressed between the lid frame 2 and the upper edge of the glass box body 1 to seal the fresh-keeping box.

[0028] The silicone pad 3 is made of silicone, which is an elastomeric material commonly used to make sealing materials, insulation materials, medical equipment, food molds, etc. Silicone has good high temperature resistance and is widely used due to its excellent high temperature resistance. It can maintain its elasticity and physical properties at extremely high temperatures and can usually work between -60 degrees Celsius and 200 degrees Celsius. The utility model uses food-grade silicone, which meets food-grade standards and can be used to make food containers, baking tools, etc. This silicone is non-toxic, tasteless, and safe for the human body.

[0029] The glass box is made of high borosilicate glass, and the lid is made of hard food-grade plastic plus silicone material.

[0030] Manufacturing process: The lid frame and the lid ear buckle are processed by injection molding machine, and the silicone pad is embedded in the recess of the frame-shaped lid to fix it, and at the same time, it has a waterproof effect of tightly fitting with the glass box body. The silicone pad is removable and cleanable. The ear buckle is connected to the lid frame, and the ear buckle is buckled with the outer edge of the glass box body to form a connection and fixation.

[0031] The utility model is used for containers that can directly store food, can be used in microwave ovens, and are resistant to high and low temperatures. The traditional hard-surface fresh-keeping box lid is changed to a silicone material, and the soft lid can be pushed upward to increase the product volume. The soft lid can also be pressed down to discharge air, and the container is in a vacuum state after the lid is tightly closed, which increases the food storage time.
