Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details of the embodiments of the present disclosure will be described with reference to the accompanying drawings.

The terminology used in the description of the embodiments of the disclosure is for the purpose of describing the embodiments of the disclosure only and is not intended to be limiting of the disclosure. Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The terms "first," "second," "third," and the like in the description and in the claims, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The word "comprising" or "comprises", and the like, is intended to mean that elements or items that are present in front of "comprising" or "comprising" are included in the word "comprising" or "comprising", and equivalents thereof, without excluding other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to denote relative positional relationships, which may also change accordingly when the absolute position of the object to be described changes.

Along with the acceleration of the life rhythm, the demands of people on takeouts are also increased, so that the workload of takeouts is improved.

During the peak period of takeaway delivery, the delivery volume of takeaway is great, but because the volume of takeaway case is less for takeaway quantity that takeaway single delivery was less, thereby reduced takeaway's work efficiency. However, if the takeout is using a larger delivery box, the takeout is delivering less volume during the off-peak period of takeout delivery, which results in waste of the interior space of the delivery box, and the delivery box with larger volume is cumbersome.

In view of the above-described technical problems, the present disclosure provides a dispenser box, as shown in fig. 1, having a large capacity state and a small capacity state, the dispenser box including a box body 1 and a cover 2. The cover body 2 comprises a capacity expansion box body 21 and a box cover 22, the box cover 22 is connected with the side wall of the capacity expansion box body 21, and the capacity expansion box body 21 is foldable. In the large capacity state, the expansion tank body 21 is unfolded, the bottom end of the expansion tank body 21 is communicated with the top end of the tank body 1, the tank body 1 and the expansion tank body 21 are used for accommodating cargoes, and the tank cover 22 is used for closing an opening at the top end of the expansion tank body 21. In the small-capacity state, the expansion tank body 21 is folded, the tank body 1 is used for accommodating goods, and the expansion tank body 21 and the tank cover 22 jointly seal the opening at the top end of the tank body 1.

The distribution box can also be called a take-out box, and the material of the box body 1 can be EPP (Expanded polypropylene, polypropylene plastic foaming material), and the EPP has good heat preservation effect. The outside of case body 1 has the heat preservation, and the heat preservation can be through the magic parcel outside at case body 1.

In a small capacity state, when it is necessary to take and put articles from the case body 1, the expansion case 21 and the case cover 22 are lifted together. In the high capacity state, the case body 1 is communicated with the expansion case 21, and when the articles need to be taken and placed from the case body 1 and the expansion case, the case cover 22 is only required to be opened.

As shown in fig. 2 and 3, in the large capacity state, the user can adjust the expansion degree of the expansion tank 21 according to the required volume, and the larger the expansion degree of the expansion tank 21, the larger the volume of the expansion tank 21. The expansion tank 21 in fig. 2 is unfolded to a greater extent than the expansion tank 21 in fig. 3, so that the volume of the expansion tank 21 in fig. 2 is greater than the volume of the expansion tank 21 in fig. 3.

According to the technical scheme provided by the embodiment of the disclosure, when the delivery amount of the takeout is large, the expansion box body 21 is unfolded, so that the delivery box is in a large-capacity state, more takeouts can be contained in the delivery box, the delivery times of the takeout are reduced, and the working efficiency of the takeout is improved. When the delivery amount of the takeout is small, the expansion tank 21 is folded so that the delivery tank is in a small capacity state, thereby making the space occupied by the delivery tank small.
