Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ice-

The present invention relates to a paper box for storing ice cream which can store products. More particularly, the present invention relates to a paper box for storing ice cream, which can store a cooling pocket for accommodating and moving and loading products.

The packaging box is used to store the product to prevent damage, and to decorate the product. As the industry develops, various kinds of packaging boxes are being manufactured as various products are produced.

In general, a box for ice cream cakes used in ice cream specialty stores or bakeries is made of a foam material having a high thermal insulation effect so that the ice cream cake does not melt.

Particularly, the ice cream cake must be secured together with dry ice for providing cold air for maintaining the temperature, and it is difficult to form a separate fixing member or a storage device for storing the dry ice in the styrofoam packing box. Therefore, at the time of selling ice cream cake, shop staff puts the ice cream cake in the packing box with adhesive tape by using the pockets containing the dry ice. However, the adhesive tape has a low adhesive force to the foam material, so that the dry ice pockets are easily separated from the packaging box, and the ice cream cake may be damaged by the dry ice pockets separated during transportation. In addition, when the dry ice pockets are fixed by using the adhesive tape, the shop staff must cut the adhesive tape one by one to fix the dry ice pockets, thereby lowering the working efficiency.

In addition, since the styrofoam packing box can not separate the internal storage space, accessories such as cake knives and candles can not be stored in the internal storage space. These accessories are put in a separate envelope, A packaging method for attaching the packaging material to the packaging material is mainly used.

Moreover, since the Styrofoam packing box can not be stored in a folded state, it is difficult to store it and also takes up a lot of storage space. In addition, since the packing box made of Styrofoam can not have a handle for gripping, a separate strap should be wrapped in a packing box for gripping during packaging. As a result, the working efficiency is lowered and the packaging time is increased.
