Description

Technical Field

[0001] The utility model relates to the field of fresh-keeping boxes, in particular to a fresh-keeping box with a novel sealing structure. Background Art

[0002] Fresh-keeping boxes can store food in different categories. They can prevent moisture from escaping, seal the food, prevent the food from losing its original flavor during storage, isolate the air, and prevent food from oxidation (infection).

[0003] However, the prior art has the following defects:

[0004] Most existing fresh-keeping boxes form a sealing structure with the box body through the sealing ring around the box lid to seal and preserve the food. However, the existing sealing structure is simple, resulting in a loose connection between the box body and the box lid, poor sealing effect, and a gap, which allows air to easily enter the box body, resulting in a short storage time of food and easy deterioration. Utility Model Content

[0005] The purpose of the utility model is to provide a fresh-keeping box with a novel sealing structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fresh-keeping box with a novel sealing structure, comprising a fresh-keeping box body and a box cover, the fresh-keeping box body being provided with a cavity inside, the top outer wall of the fresh-keeping box body being fixedly mounted with a first skirt, the bottom of the box cover being fixedly mounted with a protrusion, the protrusion being snap-fitted into the inside of the top of the fresh-keeping box body, the top outer wall of the box cover being fixedly mounted with a second skirt, the bottom of the second skirt being tightly in contact with the top of the first skirt, the bottom of the protrusion being provided with a plurality of air holes, and a blocking piece being provided in the middle of the top of the box cover.

[0007] By adopting the above technical solution, the cavity is convenient for storing food, and the protrusion is snap-fitted inside the cavity to squeeze out the air, and the box cover and the box body have overlapping parts to prevent the existence of a gap between the two. The blocking piece is pressed down to enhance the sealing performance of the fresh-keeping box.

[0008] The inner wall in the middle of the cavity is provided with a step, and the step divides the fresh-keeping box body into an upper half of the fresh-keeping box and a lower half of the fresh-keeping box, and the size of the lower half of the fresh-keeping box is smaller than that of the upper half of the fresh-keeping box.

[0009] By adopting the above technical solution, the step of the solution makes the upper part and the lower part of the fresh-keeping box different in volume, thus playing a role of separation.

[0010] The cross-sectional shapes of the fresh-keeping box body and the box cover are both hexagonal, the corners of the fresh-keeping box body and the box cover are chamfered, and the outer wall of the protrusion is tightly in contact with the inner wall of the top of the cavity.

[0011] The above technical solution is adopted. The box cover is consistent in shape with the fresh-keeping box body, which is convenient for connecting the two. The corners are chamfered to prevent sharp corners from causing damage to the user. The protrusion is tightly in contact with the inner wall of the upper half of the fresh-keeping box to ensure the sealing performance of the fresh-keeping box.

[0012] A handle is fixedly installed in the middle of one side of the second skirt, and the second skirt and the handle are both made of rubber.

[0013] The above technical solution is adopted, which makes it easy to hold the handle to open the box cover. The rubber material is soft and tough, and can be pulled, so it is convenient to remove the box cover.

[0014] A second groove is provided in the middle of the top of the box cover, and the second groove protrudes toward the bottom of the box cover to form a convex block. A top cover is fixedly installed on the inner wall of the top of the second groove, and the top cover is made of transparent PP plastic. A sealing gasket is bonded to the outer wall of the convex block.

[0015] By adopting the above technical solution, the top cover of the solution serves to close the second groove, the box cover is made of transparent material, which is easy to observe, and the sealing gasket further ensures the sealing performance of the connection between the box cover and the fresh-keeping box body, which can extend the shelf life of food.

[0016] A first groove is provided in the middle of the top of the top cover, a notch is provided on one side of the first groove, a through hole is provided in the middle of the bottom of the first groove, a plug is fixedly installed in the middle of the bottom of the blocking member, and the plug at the bottom of the blocking member is snap-fitted into the through hole at the bottom of the first groove.

[0017] By adopting the above technical solution, the first groove of the solution is convenient for installing and placing the blocking piece, and the notch is convenient for pulling the blocking piece upwards, and the gas enters the interior of the fresh-keeping box body from the through hole and the air vent, making it easy to separate the box cover and the fresh-keeping box body.

[0018] The ventilation holes are arranged in hexagonal increments at the bottom of the protrusion, and the material of the fresh-keeping box body and the protrusion are both stainless steel.

[0019] By adopting the above technical solution, the ventilation holes are evenly distributed at the bottom of the protrusion, and the stainless steel fresh-keeping box can be used for heating in an induction cooker or an electric wave oven, and refrigerated in a refrigerator, so as to keep the original flavor of the ingredients and be healthier.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The convex block at the bottom of the box cover of the utility model is tightly engaged with the inner wall of the top of the cavity, and a sealing gasket is connected to the outside of the convex block, so that the box cover can be sealed and connected to the top of the fresh-keeping box body, thereby sealing the fresh-keeping box. A plugging piece and an air hole are provided on the top of the box cover, so that the air pressure in the box can be adjusted at any time. BRIEF DESCRIPTION OF THE DRAWINGS
