Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Chinese Application No. 202021538976.1, filed on Jul. 29, 2020, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present utility model relates to a packaging box, and in particular relates to a packaging box suitable for accommodating various types of blocks.

BACKGROUND

As the standard of living has continued to increase, people have higher packaging requirements for certain block-shaped food products or medicines (referred to as “blocks”) that need to be consumed regularly. Various types of blocks are commercially available, and these blocks may have any shape, such as a cuboid shape, a spherical shape, an ellipsoidal shape, and an annular shape, or may be pellets having irregular shapes. A surface of the block may be smooth or non-smooth, for example, the surface has granules such as sugar. In addition, the block may be a hard block (for example, a chocolate block) or a soft block (for example, a soft candy).

Currently, commercially available packaging boxes for accommodating blocks, such as chewing gum packaging boxes, are relatively simple in design. Such a packaging box generally adopts a box body having a single cavity, and the box body is provided with a single outlet for accessing blocks. However, as an example, confectionery products are available in various types, and each type of confectionery products generally has a different flavor. If the packaging box is configured with a single cavity and a single outlet, if a consumer wants to taste different types of confectionery products or confectionery products having different flavors, the consumer needs to purchase multiple boxes of confectionery products, thereby resulting in inconvenience to the consumer. Furthermore, since a large number of products are purchased, it may be difficult to completely consume the products in a short time, and the products are prone to expire.

On the other hand, with regard to an existing packaging box for a confectionery product, it is generally difficult for a consumer to access the confectionery product by performing an operation on the packaging box with one hand, and it is also difficult to control the number of the confectionery products being accessed at a time. This is particularly troublesome for consumers in some use scenarios (such as during driving).

Therefore, it is necessary to provide a packaging box suitable for accommodating various types of blocks and facilitating access to the blocks so as to solve the above-mentioned problems.
