Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packing boxes, in particular to a double-layer hollow packing box. Background Art
[0002] Existing take-out packaging boxes can only meet the function of holding food. They are single-layer structures and still have great technical defects in heat preservation and cold preservation. For example, in a low-temperature environment, some catering pastries or soups are very easily affected by the surrounding environment, causing the food temperature to drop, thereby affecting the taste of the food; and in the hot summer, if people buy some cold drinks through takeout, the temperature can only be maintained by the ice inside the drink. When the ice melts, it will dilute the taste of the drink, thus failing to meet the needs of the purchaser. In addition, the single-layer packaging box mixes all the food together before eating, which is easy to affect the taste.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0027] Reference Figure 1-2 The specific embodiment of the utility model provides a double-layer empty packaging box, including:
[0028] Outer box body 3;
[0029] An inner box body 8, the top side of the inner box body 8 is mounted on the top side of the outer box body 3;
[0030] Cavity 9, a cavity 9 is set between the inner bottom of the inner box body 8 and the inner bottom of the outer box body 3;
[0031] The box cover 1 is installed on the top of the inner box body 8.
[0032] Existing take-out packaging boxes can only meet the function of holding food. They are single-layer structures and still have great technical defects in heat preservation and cold preservation. For example, in a low-temperature environment, some catering pastries or soups are very easily affected by the surrounding environment, causing the food temperature to drop, thereby affecting the taste of the food; and in the hot summer, if people buy some cold drinks through takeout, the temperature can only be maintained by the ice inside the drink. When the ice melts, it will dilute the taste of the drink, thus failing to meet the needs of the purchaser. In addition, the single-layer packaging box mixes all the food together before eating, which is easy to affect the taste. In the present application, an outer box body 3 and an inner box body 8 are provided at the same time, and the inner box body 8 is installed on the outer box body 3, and a cavity 9 is formed between the outer box body 3 and the inner box body 8; when the packing box is held by hand, the temperature inside the packing box can be effectively isolated through the cavity 9 structure, and it can also achieve a certain degree of heat preservation and cold preservation effect; on the other hand, different foods can be placed in the cavity 9 and the inner box body 8 and placed separately, thereby avoiding mutual influence between foods before eating, and can also make full use of the packaging space; on the whole, the present application has a simple structure, which can achieve the effect of heat preservation and cold preservation, and can also hold food separately.
[0033] Further optimization plans also include:
[0034] A third flange 7, which is arranged on the top side of the outer box body 3, and the inner box body 8 is installed on the outer box body 3 through the third flange 7;
[0035] The second flange 6 is arranged on the top side of the inner box body 8 , and the third flange 7 is clamped under the second flange 6 .
[0036] The inner box body 8 is installed on the outer box body 3 by snapping the third flange 7 into the second flange 6. Due to the flange structure, when the inner box body 8 is filled with soup, it can effectively prevent the soup from entering the cavity 9 during transportation, further avoiding affecting the food in the cavity 9.
[0037] Further optimization plans also include:
[0038] The first flange 2 is arranged on the top side of the box cover 1 , and the first flange 2 is clamped on the top of the second flange 6 .
[0039] The box cover 1 is mounted on the second flange 6 of the inner box body 8 through the first flange 2. The connection structure is simple and easy to open or close. It can also effectively prevent the food or soup in the inner box body 8 from spilling.
[0040] Further optimization plans also include:
[0041] The convex ridge pattern 4 is arranged on the bottom peripheral side of the outer box body 3.
[0042] The main function of the ridge pattern 4 is to prevent the bottom of the outer box body 3 from being too smooth, so that the hand can more easily hold the outer box body 3 when holding the packaging box.
[0043] Further optimization plans also include:
[0044] The bowl holder 5 is arranged at the bottom of the outer box body 3 , and the ridge pattern 4 is located on the peripheral side of the bowl holder 5 .
[0045] like Figure 2 As shown, the bowl holder 5 is an annular structure protruding from the bottom of the outer box body 3, which can effectively assist the entire package box to be placed stably on a plane; at the same time, it can also assist the hand to hold the bottom of the package box during eating, making it more stable.
