[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] The embodiments of the present application provide a stretchable day and night box, which solves the problem that the conventional day and night box in the market cannot be quickly opened.

[0037] In order to better understand the above technical scheme, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0038] The embodiments of the present application disclose a stretchable day and night box, such as Figures 1-11As shown, the enclosure includes an outer top box 1, an inner top box 2, and a bottom box 3. The top box consists of two different nested cardboard boxes: an outer top box and an inner top box. The length of the outer top box is approximately three-quarters the length of the inner top box, and its width and height should be slightly longer than the inner top box by a few millimeters. The top box has an internal tensioning structure and a limiting structure. The tensioning structure consists of two grooved tracks located on both sides inside the outer top box. The limiting structure consists of two protruding rectangular limiting strips located on both sides inside the outer top box. After the inner and outer top boxes are nested, the bottom strip of the inner box can be folded to tightly press the inner and outer boxes together, preventing them from easily separating.

[0039] The specific structure is as follows:

[0040] The outer top box 1 and the inner top box 2 are equipped with a tension structure and a limiting structure.

[0041] The tensioning structure is a grooved track, such as Figure 7 As shown, it consists of an outer side 102 of the first side of the outer top box, an inner side 104 of the first side of the outer top box, an outer side 106 of the third side of the outer top box, and an inner side 108 of the third side of the outer top box.

[0042] Specifically, such as Figure 7 As shown, after the outer top box's first side interior 104 is folded, it can form a track extending into the box with the outer side exterior 102 of the outer top box's first side, so that the inner top box's first side exterior 202 and the inner top box's first side interior 204 can be inserted into it after being folded and fitted together.

[0043] Specifically, such as Figure 7 As shown, the inner 106 of the third side of the outer top box and the outer 108 of the third side of the outer top box can also form the same track, so that the outer 206 of the third side of the inner top box and the inner 208 of the third side of the inner top box can be inserted into it after being folded and fitted together;

[0044] Furthermore, the inner top box 2 is inserted into the outer top box 1 along the grooved track. After the inner top box is inserted into the outer top box, the center surface 201 of the inner top box... Figure 2 As shown, it is tightly fitted to the center surface 101 of the outer top box;

[0045] Furthermore, such as Figures 3-4 As shown, the top box can be freely stretched with the help of the track. Users can use the stretching structure to separate the outer top box 1 from the inner top box 2 by a certain distance, thereby increasing the space for removing the ground box and making it easier to take out the ground box.

[0046] Limiting structures, such as Figure 7As shown, the first limiting strip 1041 and the second limiting strip 1081 of the outer layer of the box are used to press the inner layer of the box.

[0047] Specifically, as shown in the figure, Figures 5-6 As shown, after the inner layer of the box 2 is inserted into the outer layer of the box 1, the bottom surface 207 of the inner layer of the box is turned out, and then the first limiting strip 1041 and the second limiting strip 1081 are used to press the inner layer of the box.

[0048] The center surface 201 of the inner layer of the box, and then the first limiting strip 1041 and the second limiting strip 1082 are pressed under the bottom surface 207 of the inner layer of the box to fix them. At this time, after the inner layer of the box 2 is stretched for a distance, the connection between the bottom surface 207 of the inner layer of the box and the center surface 201 of the inner layer of the box will touch the limiting strip 1041 and the limiting strip 1081, so that the box cannot be stretched further, achieving the effect of preventing the user from stretching too much and causing the box to disintegrate.

[0049] When the outer layer of the box is made, as shown in the figure, Figure 10 First, the dashed line part of the connecting surface 1021 should be bent to make the first side surface outside 102 of the outer layer of the box, the third side surface 106 of the outer layer of the box, and the second side surface outside 103 of the outer layer of the box close together, and then the first side surface inside 104 of the outer layer of the box and the third side surface inside 108 of the outer layer of the box are folded to the inside of the outer layer of the box, and then the first side surface inside 105 of the outer layer of the box is folded to press the first insertion tongue 1042 and the second connecting surface 2021, thereby fixing all the side surfaces. After completion, the bottom surface 107 of the outer layer of the box is folded to press the first top pressing tongue 1051, but not to press the first limiting strip 1041 and the second limiting strip 1081. It should be noted that the two limiting strips are fixed after the inner and outer layers of the box are inserted together.

[0050] When the inner layer of the box is made, as shown in the figure, Figure 11 First, the dashed line part of the second connecting surface 2021 should be bent to make the first side surface outside 202 of the inner layer of the box and the second side surface outside 203 of the inner layer of the box close together, and then the first side surface inside 204 of the inner layer of the box and the third side surface inside 208 of the inner layer of the box are folded to the inside of the inner layer of the box, and then the second side surface inside 205 of the inner layer of the box is folded to press the second insertion tongue 2042 and the second connecting surface 2021, thereby fixing all the side surfaces. At this time, the second top pressing tongue 2051 and the side pressing tongue 2041 do not need to be pressed by the bottom surface 207 of the inner layer of the box, as shown in the figure, Figure 8 After the inner layer of the box 2 is inserted into the outer layer of the box 1, the bottom surface 207 of the inner layer of the box is used to press the first limiting strip 1041, the second limiting strip 1081, the second top pressing tongue 2051, and the side pressing tongue 2041, as shown in the figure, Figure 5 to fix the box.

[0051] Further, as shown in the figure,Figures 1-2 As shown, the length of the outer layer is about three quarters of the length of the inner box, and the width and height should be 1-3 mm longer than the inner layer, but the specific length should be determined according to the overall size of the outer layer, so that the inner layer is inserted into the outer layer of the box, but not

[0052] The internal space of the groove type track is too large, so that the two box bodies have good inductance.

[0053] In summary: the stretchable box, by using the stretching structure and the limiting structure, the user can open the box more quickly, the manufacturing is simple, the structure is stable, on the basis of the product function, the user is provided with better use experience, and finally the purpose of improving the consumer's favorability is achieved.

[0054] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the embodiment, for the skilled in the art, it still can modify the technical scheme recorded in each embodiment, or equivalent replacement to part of the technical features, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
