Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging, in particular to an aluminum foil sealing structure. Background Art
[0002] With the acceleration of the pace of society and the rise of pre-prepared meals, the food packaging industry is booming. The common milk powder can lids, meat sauce can lids, dace box lids, and wine glass lids on the market are all made of hard iron sheets or stainless steel sheets. However, when opening the lids, the pull rings are often too sharp and cut the hands, which poses a safety hazard. Nowadays, many businesses use plastic films to seal pre-prepared meal boxes and pre-prepared meal bowls. However, since pre-prepared meals belong to an emerging industry, safety supervision is relatively lacking. In order to save costs, many unscrupulous businesses use inferior or food safety-exceeding films as pre-prepared meal box lids or bowl lids, which endanger the health of pre-prepared meal consumers. In addition, the recycling rate of film products is low and not environmentally friendly. As a manufacturer in the food industry, there is an urgent need for a sealing product that is both environmentally friendly, does not hurt the hands, and does not affect the health of consumers. Utility Model Content
[0003] The purpose of the utility model is to provide a vegetable box cover to solve the problems raised in the above background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] An aluminum foil sealing structure comprises a sealing body made of aluminum foil, wherein a circle of adhesive layer matching the shape of a can mouth, a cup mouth, a box mouth or a bowl mouth is arranged on the periphery of the bottom of the sealing body, a tear handle is integrally formed on one side of the sealing body, an arc transition structure is provided between the tear handle and the edge of the sealing body, and the side of the tear handle away from the sealing body is an arc structure.
[0006] Preferably, a fold line is pressed in the middle of the cover body.
[0007] Preferably, a text pattern layer is printed on the upper surface of the cover body.
[0008] Preferably, the tear handle is an isosceles trapezoidal structure.
[0009] Preferably, the adhesive layer is a hot melt adhesive layer or a cold seal adhesive layer.
[0010] The utility model applies a circle of adhesive layer that matches the shape of the mouth of a food container such as a can mouth, a cup mouth, a box mouth or a bowl mouth on the outer periphery of the bottom of the cover body, and the rest of the parts have no other coatings, which not only makes the cover body tightly bonded to the can mouth, cup mouth, box mouth or bowl mouth, protecting the food inside from spilling or leaking, but also ensures the hygiene of the food inside and protects the health of the eater. When the user opens the cover body by tearing the handle, when it opens to the crease line, the opened part can be folded without affecting the use, and the cover body is still adhered to the food container, which is convenient for recycling, improves the recycling rate and also maintains the appearance of the city. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the utility model;
[0012] Figure 2 It is a bottom view of the utility model;
[0013] In the figure: 1. Cover body; 2. Text pattern layer; 3. Tear handle; 31. Arc transition structure; 32. Arc structure; 4. Adhesive layer; 5. Crease line. DETAILED DESCRIPTION
[0014] See also Figure 1-Figure 2 , an aluminum foil cover structure, comprising a cover body 1 made of aluminum foil, a circle of adhesive layer 4 matching the shape of a can mouth, a cup mouth, a box mouth or a bowl mouth is arranged on the periphery of the bottom of the cover body 1, a tear handle 3 is integrally formed on one side of the cover body 1, a circular arc transition structure 31 is provided between the tear handle 3 and the edge of the cover body 1, and the side of the tear handle 3 away from the cover body 1 is a circular arc structure 32. The cover body 1 and the tear handle 3 made of aluminum foil, by utilizing the softness and texture of the aluminum foil, will not cut the hand, and can also improve the grade of the product. Only a circle of adhesive layer 4 matching the shape of the mouth of a food container such as a can mouth, a cup mouth, a box mouth or a bowl mouth is arranged at the bottom of the cover body 1, and there is no other coating on the other parts, which not only makes the cover body 1 tightly bonded to the can mouth, the cup mouth, the box mouth or the bowl mouth, protects the food inside from spilling or leaking, but also ensures the hygiene of the food inside, and protects the health of the eater.
[0015] A crease line 5 is pressed in the middle of the cover body 1. In order to prevent people from throwing away the cover body 1 randomly after tearing it completely, which affects the appearance of the city, a crease line 5 is pressed in the middle of the cover body 1. When the user opens the cover body 1 by tearing the handle 3, the opened part can be folded when it reaches the crease line 5, which does not affect the use. The cover body 1 is still attached to the food container, which is convenient for recycling, improves the recycling rate and maintains the appearance of the city; when used for milk powder cans, it can also play the role of scraping the milk powder spoon.
[0016] The upper surface of the cover body 1 is printed with a text pattern layer 2. The text pattern layer 2 can be business information or product promotion patterns. The tear handle 3 is an isosceles trapezoidal structure. The adhesive layer is a hot melt adhesive layer or a cold seal adhesive layer.
