In the utility model, the left and right and the upper and lower are structural differences and do not represent absolute directions. The positions may not be consistent according to the position adjustment of the packaging box, so they cannot be used as a restriction on the protection scope of the patent.
[0013] By Figures 1 to 3The utility model discloses intelligent temperature sensing environment -friendly cake packaging box, including the bottom box 100 that corrugated paper is folded and the upper cover 200 that buckling is at its opening, the bottom box 100 is cut and folded from a corrugated paper board, including bottom plate 10, the vertical flaps 20 that is set up symmetrically along the bottom plate 10 left and right two side edges extension, the horizontal flaps 30 that is set up symmetrically along bottom plate 10 upper and lower two edges extension, double -deck clamping plate 40 is extended respectively in the horizontal flaps 30 left and right two sides, when the bottom box is folded, the vertical flaps 20 is inserted in the interlayer of double -deck clamping plate 40, the exposed part of vertical flaps 20, horizontal flaps 30 or upper cover 200 is printed with the pattern 300 printed by temperature sensing ink. With the development of science and technology and the improvement of people's living standards, the functional demand of enterprises on paper packaging is higher and higher, in addition to the basic requirements of protection, transportation, sale and the like, packaging with certain anti-counterfeiting function has greater development potential, especially in the field of food and drug packaging. If the regular production factory produces hamburger, pizza and other boxed frozen food purchased from supermarket, the shelf life is marked on the packaging box, but the food in the box appears deterioration, taste change or even odor, which brings unnecessary trouble to consumers and businessmen. The reason is that the temperature of these foods is too high during transportation, storage and sales, resulting in deterioration, taste change and the like within the shelf life, and consumers and businessmen cannot see whether the food is deteriorated from the outer packaging. If temperature-induced color change ink is used, the word "temperature too high" is printed on the outer packaging, when the external temperature exceeds the highest critical value of the food suitable for storage, the warning word will appear, and when the external temperature is within the temperature range suitable for food storage, the word will not appear. In this way, consumers and businessmen can be reminded to store perishable food reasonably, thereby avoiding cost increase and food waste, and the outer packaging of transportation and storage can be reused. The types of cakes on the market are increasing, and animal butter cakes and ice cream cakes become the preferred choice of consumers, and both types of cakes need to be stored at low temperature to ensure the quality and flavor of the cakes. In response to the development of the industry situation. The packaging box designed by the utility model is folded from a paper board, and the four side edges of the bottom box form a multilayer structure due to folding and insertion structure, which can effectively protect the strength of the packaging, and the insertion and clamping structure of the four side edges facilitates assembly and disassembly, and also prevents the use of adhesive glue from polluting and affecting the taste of the food.
[0014] By Figure 2 And Figure 3The utility model discloses a structure optimization design for the transverse folding plate 30 is two folding plates, including the first transverse folding plate 31 and the second transverse folding plate 32 of the extension setting of first transverse folding plate 31 and second transverse folding plate 32 along bottom plate 10 in proper order, and the clamping plate is extended to both sides of first transverse folding plate 31 and second transverse folding plate 32 to constitute double -deck clamping plate 40. First transverse folding plate 31 and second transverse folding plate 32 are equal height and width, and constitute the transverse folding plate 30 of double -deck structure after folding, and the clamping plate of second transverse folding plate 32 setting on both sides is equal height with second transverse folding plate 32, and the non -folding edge is cut into bevel on it, and the clamping plate of first transverse folding plate 31 setting on both sides is slightly lower than the height of first transverse folding plate 31, and the non -folding edge is also cut into bevel on it. For the design of bottom box, the first transverse folding plate 31 and the second transverse folding plate 32 in the scheme constitute the transverse plate of double -deck after folding, improve the anti -impact performance of transverse, and the structure of vertical plate is designed to constitute the structure of multilayer by vertical folding plate and double -deck clamping plate, and also, improve the anti -impact performance of vertical. And the part edge of clamping plate is cut into bevel, mainly convenient for inserting, also to guarantee the regularity of bottom box, and the clamping plate of outside design is short, one aspect makes vertical folding plate can be partially exposed outside, can print ink, and another aspect also convenient for disassembly.
[0015] The temperature-sensitive ink is reversibly temperature-sensitive ink, and the temperature-sensitive microcapsule ink is reversibly temperature-sensitive ink. The interval memory temperature-sensitive paper packaging is a kind of functional packaging, when the temperature reaches a certain range, the color of the paper changes, and when the temperature returns to the initial temperature, the color will also recover. The mutual integration of various disciplines in the material field provides new ideas and methods for the research and preparation of new functional paper. In 1993, DelSo1 company applied reversible temperature-induced color-changing materials to the pulp system and invented interval memory temperature-sensitive paper. Since then, with the mutual integration and development of various disciplines in the material field, its technology has gradually matured. At present, the research and development of this product in the United States, Japan and other countries are in the leading position, and many have been productized, but there are few reports on interval memory temperature-sensitive paper packaging in China. The color-changing temperature of the reversible temperature-induced color-changing ink used in the interval memory temperature-sensitive paper packaging has a decisive effect on the interval memory color-changing temperature of the paper packaging. The reversible temperature-induced color-changing ink belongs to a kind of temperature-sensitive ink, and the temperature-sensitive ink is a kind of special ink whose color changes when the temperature changes. Therefore, the ink has rich dynamic color effect. Temperature-sensitive ink can be roughly divided into two categories: irreversible temperature-sensitive ink and reversible temperature-sensitive ink. Irreversible temperature-sensitive ink refers to ink whose printed text color changes when the material is heated to a certain temperature, and cannot restore to the original color when cooled. Because the color-changing material of irreversible temperature-sensitive ink is mainly heavy metal elements, and the color-changing temperature is high, it does not meet the green environmental protection requirements, so it is gradually replaced by reversible temperature-sensitive ink in the fierce market competition. Reversible temperature-sensitive ink refers to the material that is heated to a certain temperature, and the printed text color changes obviously, and when the temperature returns to the original temperature, it can restore to the original color, and the change process is reversible, and can achieve memory color in a certain temperature interval. At present, reversible temperature-induced color-changing ink is divided into three categories: inorganic reversible temperature-induced color-changing ink, organic reversible temperature-induced color-changing ink and liquid crystal reversible temperature-induced color-changing ink, and their color-changing principles are different. Among the existing three kinds of reversible temperature-induced color-changing inks, the comprehensive color performance of organic type is the best, and it is the most potential temperature-induced color-changing ink at present. It has the advantages of low color-changing temperature, high sensitivity, free color selection, long color life and is widely used in anti-fake printing, decoration, personalized products and promotion in daily life. In addition, with the improvement of the public's environmental protection consciousness and the continuous increase of people's attention to "white pollution", paper packaging accounts for a higher and higher proportion in people's life, and interval memory temperature-sensitive paper packaging with excellent performance has broad development prospects and brings huge social and economic benefits.
[0016] The bottom box 100 and the upper cover of the utility model are all made of E-pit corrugated paperboard, mainly to improve the bearing capacity while minimizing the thickness of the packaging box, facilitating lightness.
[0017] From Figure 4 It is known that the upper cover 200 is also a cutting and folding of an E-pit corrugated paperboard, comprising a cover plate 50, vertical double-layered folding plates 60 symmetrically arranged along the left and right side edges of the cover plate 50, horizontal double-layered folding plates 70 symmetrically arranged along the upper and lower side edges of the cover plate 50, and a plug 71 arranged along the left and right sides of the horizontal double-layered folding plates 70. When the upper cover is folded, the plug 71 is inserted into the interlayer of the vertical double-layered folding plates 60 on both sides. The structure design adopts a plug-in mode for fixation, which is mainly to avoid affecting the quality and taste of food, and is also convenient for assembly and disassembly.
[0018] The above is a further detailed description of the present application in combination with specific preferred embodiments, and the specific implementation of the present application cannot be limited to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, a number of simple deductions or substitutions can be made without departing from the concept of the present application, and all of them should be regarded as falling within the protection scope of the present application.
