Technical Field
[0001] The utility model relates to the technical field of blister lunch boxes, in particular to a blister lunch box. Background Art
[0002] Blister boxes, in a broad sense, refer to all blister boxes. In a narrow sense, they are just one type of blister box: a plastic box is formed from sheet material into a box-like shape, with the lid attached to the container. They are mostly made of PS, but some have separate lids and bottoms, and different materials can be used. For example, Japanese fast food boxes use black PS for the bottom and transparent PET for the lid. Blister boxes, in a broad sense, refer to all blister boxes. In a narrow sense, they are just one type of blister box: a plastic box is formed from sheet material into a box-like shape, with the lid attached to the container. They are mostly made of PS, but some have separate lids and bottoms, and different materials can be used. Existing fast food boxes use black PS for the bottom and transparent PET for the lid. Existing blister boxes cannot be tightly sealed after food is placed in them, causing the heat of the food to dissipate quickly. At the same time, tightly closed blister boxes are not only inconvenient to open a second time, but can also easily damage the blister box during the opening process, and may even cause food to spill. Utility Model Content
[0003] In order to solve the above-mentioned problem that the existing blister lunch box cannot be tightly sealed after the food is placed in it, which causes the heat of the food to dissipate quickly, and at the same time, the tightly closed blister lunch box is not only inconvenient to open for the second time, but the opening process can easily damage the blister box body and even cause food to splash out. The above-mentioned purposes of quick and tight sealing, good heat preservation effect, convenient opening operation, prevention of damage to the lunch box and practicality are achieved. The present utility model is achieved through the following technical solutions: a blister lunch box, comprising a box body, an inner surface of the box body is provided with a card slot, the outside of the box body is fixedly connected to a connecting belt, the outside of the connecting belt is fixedly connected to a pressing column, the outside of the box body is fixedly connected to a flexible connecting plate, the outside of the flexible connecting plate is fixedly connected to a box cover, the outside of the box cover is fixedly connected to a clamping ring, and the outer surface of the box cover is provided with a fastening hole.
[0004] Furthermore, the position of the box body and the box cover corresponds to each other and their specifications match each other, the position of the card slot and the card ring corresponds to each other and their specifications match each other, the number of the connecting belts is two, and the two connecting belts are symmetrically distributed on the outside of the box body; the position of the pressing column and the fastening hole correspond to each other and their specifications match each other, the flexible connecting plate has good elasticity and can be deformed arbitrarily as the box cover and the box body are closed, the number of the fastening holes is two, and the two fastening holes are symmetrically distributed on the surface of the box cover.
[0005] The utility model provides a blister lunch box with the following beneficial effects:
[0006] 1. The blister lunch box cooperates with the card slot and the card ring, so that the box body and the box lid are quickly and tightly sealed, which improves the heat preservation and sealing performance of the blister lunch box. At the same time, the movement of the pressing column drives the movement of the connecting belt, and the movement of the pressing column cooperates with the fastening hole, so that the cover of the blister lunch box is more reliable. At the same time, the card slot and the card ring are coordinated, and the pressing column and the fastening hole are coordinated, which makes the secondary opening of the blister lunch box more convenient to operate, prevents the blister lunch box from splashing food and damaging the lunch box when it is opened for the second time, and improves the practicality of the blister lunch box.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0013] The embodiment of this blister lunch box is as follows:
[0014] See also Figure 1 - Figure 4, a blister lunch box, comprising a box body 1, a card slot 2 is opened on the inner surface of the box body 1, a connecting belt 3 is fixedly connected to the outside of the box body 1, a pressing column 4 is fixedly connected to the outside of the connecting belt 3, a soft connecting plate 5 is fixedly connected to the outside of the box body 1, a box cover 6 is fixedly connected to the outside of the soft connecting plate 5, a snap ring 7 is fixedly connected to the outside of the box cover 6, the position of the box body 1 and the box cover 6 correspond to each other and the specifications match, the card slot 2 and the position of the snap ring 7 correspond to each other and the specifications match, the number of connecting belts 3 is two, and the two connecting belts 3 are symmetrically distributed on the outside of the box body 1, a fastening hole 8 is opened on the outer surface of the box cover 6, the position of the pressing column 4 and the fastening hole 8 correspond to each other and the specifications match, the soft connecting plate 5 has a relatively Good elasticity can arbitrarily deform as the box cover 6 and the box body 1 are closed. There are two fastening holes 8, and the two fastening holes 8 are symmetrically distributed on the surface of the box cover 6. The card slot 2 cooperates with the snap ring 7, so that the box body 1 and the box cover 6 are quickly and tightly sealed, thereby improving the heat preservation and sealing properties of the blister lunch box. At the same time, the movement of the pressing column 4 drives the movement of the connecting belt 3, and the movement of the pressing column 4 cooperates with the fastening hole 8, thereby making the closing of the blister lunch box more reliable. At the same time, the card slot 2 and the snap ring 7 are cooperated, and the pressing column 4 cooperates with the fastening hole 8, which makes the secondary opening of the blister lunch box more convenient to operate, prevents the blister lunch box from splashing food and damaging the lunch box due to the secondary opening, and improves the practicality of the blister lunch box.
[0015] Working principle:
[0016] The user puts food into the inner side of the box body 1 and manually drives the box cover 6 to rotate. The rotation of the box cover 6 drives the snap ring 7 to move. The rotation of the box cover 6 causes the flexible connecting plate 5 to deform. The movement of the box cover 6 drives the snap ring 7 to move until it contacts the inner side of the card slot 2 and inserts into its inner side. The box cover 6 cooperates with the box body 1. The user manually picks up the pressing column 4 and moves it. The movement of the pressing column 4 drives the connecting belt 3 to move and deform. The pressing column 4 moves to contact the inner side of the fastening hole 8 on the surface of the box cover 6 and inserts into its inner side, thereby fixing the box body 1 and the box cover 6.
[0017] To open the blister lunch box, the user only needs to manually lift the pressing column 4 and separate it from the fastening hole 8, and at the same time hold the box body 1 and the box cover 6 with both hands respectively and move the box cover 6 to drive the clamping ring 7 to separate from the clamping slot 2, so that the blister lunch box can be easily opened.
[0018] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
