Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of Chinese Patent Application No. 202021538976.1, filed on July 29, 2020, which is incorporated herein by reference in its entirety.

[0002] FIELD OF THE INVENTION The present invention relates to a packing box, and more particularly to a packing box suitable for storing various types of blocks. [Background technology]

[0003] As living standards continue to improve, people have higher packaging requirements for certain block-shaped foods or drugs (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 cube, a sphere, an oval, and a ring, or may be pellets with an irregular shape. The surface of the block may be smooth or uneven, for example, the surface may have granules such as sugar. In addition, the block may be a hard block (e.g., a chocolate block) or a soft block (e.g., a soft candy).

[0004] Currently, commercially available packing boxes for containing blocks, such as packing boxes for chewing gum, have a relatively simple design. Such packing boxes generally employ a box body with a single cavity, and the box body is provided with a single exit for accessing the blocks. However, as an example, confectionery products are available in various types, and each type of confectionery product generally has a different flavor. If the packing box is configured with a single cavity and a single exit, if a consumer wants to taste different types of confectionery products or confectionery products with different flavors, the consumer would need to purchase multiple boxes of the confectionery products, which would cause inconvenience to the consumer. Furthermore, since a large number of products are purchased, it may be difficult to fully consume the products in a short period of time, and the products will expire.

[0005] On the other hand, with regard to existing packaging boxes for confectionery products, it is generally difficult for consumers to access the confectionery products by manipulating the packaging box with one hand, and furthermore, it is difficult to control the number of confectionery products accessed at one time, which is particularly problematic for consumers in some usage scenarios (such as while driving).

[0006] Therefore, to solve the above-mentioned problems, it is necessary to provide a suitable packaging box for storing various types of blocks and for facilitating access to the blocks. Summary of the Invention [Means for solving the problem]

[0034] As shown in FIGS. 1 and 2 , a packaging box 1 according to one embodiment of the present invention includes an upper cover 11 and a lower cover 12. The upper cover 11 and the lower cover 12 can be combined to form an internal packaging space for accommodating blocks therein. The packaging box 1 further includes at least one spacer 13 provided inside at least one of the upper cover 11 and the lower cover 12. When the upper cover 11 and the lower cover 12 are combined, the spacer 13 can divide the internal packaging space into at least a left cavity and a right cavity. In the embodiment shown in FIGS. 4 and 5 , a spacer is provided inside each of the upper cover 11 and the lower cover 12, i.e., a spacer 131 is provided inside the upper cover 11, and a spacer 132 is provided inside the lower cover 12. However, those skilled in the art will understand that the spacer may be provided only in the upper cover or only in the lower cover as long as it can divide the internal packaging space, and the present invention is not limited thereto.

[0035] In this embodiment, the left and right cavities have left and right outlets, respectively, and at least one of the top cover 11 and the bottom cover 12 is provided with at least one flip cover 14. The at least one flip cover 14 can be flipped vertically to close or open the left and / or right outlets. As shown in FIG. 5 , in this embodiment, the at least one flip cover 14 includes two flip covers. The two flip covers are a left flip cover 141 and a right flip cover 142. The left flip cover 141 and the right flip cover 142 are used to close or open the left and right outlets, respectively, and the left flip cover 141 and the right flip cover 142 are provided on the bottom cover 12. Similarly, those skilled in the art will understand that both the left flip cover 141 and the right flip cover 142 may be provided on the upper cover 11, or the left flip cover 141 and the right flip cover 142 may be provided on the upper cover 11 and the lower cover 12, respectively, as long as the left and right exits can be closed or opened, and the present invention is not limited thereto. In other embodiments not illustrated in the present invention, the at least one flip cover 14 may be one flip cover, and one flip cover may be provided on the upper cover 11 or the lower cover 12, and may close or open the left and right exits simultaneously.

[0036] It should be noted that in this embodiment, the left flip cover 141 and the right flip cover 142 are connected to the bottom cover 12 by hinges. However, the present invention is not limited thereto, and any suitable connection method capable of implementing the connection between the flip covers falls within the scope of protection of the present invention. In addition, in this embodiment, the description is provided based on the left flip cover 141 and the right flip cover 142 having almost the same configuration. However, those skilled in the art will understand that the left flip cover 141 and the right flip cover 142 may have slightly different configurations, and the present invention is not limited thereto.

[0037] In the embodiment shown in FIGS. 1 and 2, the packaging box 1 is depicted as a flat rectangular box. Specifically, as shown in FIGS. 3 and 4, the upper cover 11 has a pair of parallel long edges 111 and 112 and a pair of parallel short edges 113 and 114 perpendicular to the pair of parallel long edges 111 and 112. As shown in FIGS. 5 and 6, the lower cover 12 has a pair of parallel long edges 121 and 122 and a pair of parallel short edges 123 and 124 perpendicular to the pair of parallel long edges 121 and 122. Certainly, those skilled in the art will understand that the specific implementation of the packaging box can be adjusted according to actual requirements. For example, the packaging box may have other suitable shapes, including, but not limited to, a circular box, an oval box, a cylindrical box, etc., and the packaging box may be non-flat, and the present invention is not limited thereto.

[0038] Continuing to refer to FIGS. 3 to 6 , in this embodiment, spacer 131 is shown as a linear ridge parallel to short edges 113 and 114 and is provided at a central position inside upper cover 11. Spacer 132 is shown as a linear ridge parallel to short edges 123 and 124 and is provided at a central position inside lower cover 12. When upper cover 11 and lower cover 12 are combined, spacer 131 and spacer 132 are combined together to divide the internal packaging space into a left cavity and a right cavity having the same size. Similarly, those skilled in the art will understand that the shape and position of the spacers can be flexibly configured according to actual requirements. In other embodiments not illustrated in this utility model, the spacer may be a curved ridge or a spacer part having a reinforcing structure, etc., and this utility model is not limited thereto. In addition, in other embodiments not illustrated in this utility model, the spacer may not be positioned at the middle position so that the internal packaging space of the packaging box can be divided into left and right cavities having different sizes. In this case, the manufacturer can pre-configure the sizes of the left and right cavities according to the consumer's purchasing preferences. The relatively larger cavities can be used to accommodate products frequently purchased by consumers, and the relatively smaller cavities can be used to accommodate products less frequently purchased by consumers or samples of new products to be used, thereby further improving the consumer's user experience.

[0039] In the embodiment of the present invention, as shown in Figures 3 and 4, an upper notch is provided in a portion of the long edge 111 of the side of the upper cover 11, including the end of the spacer 131. As shown in Figure 5, a lower notch is provided in a portion of the long edge 121 of the side of the lower cover 12, including the end of the spacer 132, and the position of the upper notch corresponds to the position of the lower notch. When the upper cover 11 and the lower cover 12 are combined, the upper notch of the upper cover 11, the lower notch of the lower cover 12, the spacer 131, and the spacer 132 together form a left outlet of the left cavity and a right outlet of the right cavity. In other embodiments not illustrated in the present invention, the spacers may not play a role as part of forming the left and right outlets. That is, the upper cover 11 may be provided with a first upper notch at the position of the left long edges 111 and 112 or short edge 113 of the spacer 131, and the lower cover 12 may be provided with a first lower notch at the position of the left long edges 121 and 122 or short edge 123 of the spacer 132, the position of the first upper notch corresponding to the position of the first lower notch. Similarly, the upper cover 11 may be provided with a second upper notch at the position of the right long edges 111 and 112 or short edge 114 of the spacer 131, and the lower cover 12 may be provided with a second lower notch at the position of the right long edges 121 and 122 or short edge 124 of the spacer 132, the position of the second upper notch corresponding to the position of the second lower notch. When the upper cover 11 and the lower cover 12 are combined, the first upper notch of the upper cover 11 and the first lower notch of the lower cover 12 form a left outlet for the left cavity, and the second upper notch of the upper cover 11 and the second lower notch of the lower cover 12 form a right outlet for the right cavity.

[0040] In the embodiment shown in FIGS. 1 to 6, the description is provided based on the assumption that the left and right outlets have the same shape and size. However, those skilled in the art will understand that the shape of the left outlet may differ from the shape of the right outlet, the size of the left outlet may differ from the size of the right outlet, and the shape and size of the outlets can be flexibly configured according to the specific shape and size of the block to be housed therein, and that the present utility model is not limited thereto. In the embodiment shown in FIGS. 1 to 6, the left and right outlets are provided on the same side of the packaging box and are adjacent to each other so that a consumer can easily open and close the left and right outlets by holding the packaging box with one hand. Preferably, the distance between the left and right outlets is 1 / 10 or less of the length of the long edge of the packaging box. More preferably, the distance between the left and right outlets is 1 / 20 or less of the length of the long edge of the packaging box. However, the present utility model is not limited thereto. In other embodiments not illustrated in this utility model, for example in technical solutions in which the spacer does not serve as part of forming the left and right outlets, the left and right outlets may be provided on different sides of the packaging box or may not be adjacent to each other.

[0041] According to an embodiment of the present invention, as shown in Fig. 5, the free end of the left flip cover 141 has a protruding portion 1411, and the free end of the right flip cover 142 has a protruding portion 1421. As shown in Fig. 3, a recess 115 is provided on the outer surface of the top cover 11 corresponding to the upper notch, and the recess 115 has a length substantially equal to that of the upper notch. When the left flip cover 141 and the right flip cover 142 are closed, the protruding portion 1411 and the protruding portion 1421 can engage with the side surfaces of the recess 115 to form an appearance substantially matching the appearance of the side wall portions of the packaging box. The width of the recess 115 can be designed to allow fingers to easily apply force to open the flip covers.

[0042] In this embodiment of the present invention, the left cavity is preferably further provided with a gradually inclined left guide rail extending from the left edge of the left outlet to the left short edge of one of the upper and lower covers, and the right cavity is further provided with a gradually inclined right guide rail extending from the right edge of the right outlet to the right short edge of one of the upper and lower covers. The left and right guide rails are used to guide the blocks stored therein to the left and right outlets, respectively, to facilitate access to the blocks. As shown in FIG. 5 , in this embodiment, the left cavity is provided with a gradually inclined left guide rail 151 extending from the left edge of the left outlet to the short edge 123 of the lower cover 12, and the right cavity is provided with a gradually inclined right guide rail 152 extending from the right edge of the right outlet to the short edge 124 of the lower cover 12. In other embodiments not illustrated in this utility model, the left guide rail or the right guide rail may also be provided on the upper cover, and this utility model is not limited thereto. In addition, in the embodiment shown in Fig. 5, the illustration and explanation are based on the left guide rail and the right guide rail being in the form of a ridge. However, those skilled in the art will understand that the left guide rail and the right guide rail may also be configured with other structures or forms, for example, the left guide rail and the right guide rail may have a structure with a hollow / solid portion, as long as the block can be guided by its outer edge, and this utility model is not limited thereto.

As shown in FIG. 7, the radius of the lower rounded corners is larger than the radius of the upper rounded corners, and the rounded corners of the lower cover 12 are larger than the rounded corners of the upper cover 11, thereby further improving comfort for the user during holding. In some embodiments, the lower cover 12 may have a height substantially equal to the radius of the lower rounded corners, and the upper cover 11 may have a height substantially equal to the radius of the upper rounded corners. In the embodiment shown in this utility model, the description is provided based on the fact that both the side surfaces of the upper cover and the lower cover have rounded corners. However, those skilled in the art will understand that the side surfaces of the lower cover may have rounded corners, but the side surfaces of the upper cover may not have rounded corners (e.g., may have square corners), and that this utility model is not limited thereto.

[0046] According to an embodiment of the present invention, as shown in FIG. 7 , an upper dovetail structure 116 is formed on a side edge of the upper cover 11 other than the upper notch. A lower dovetail structure 125 is formed on a side edge of the lower cover 12 other than the lower notch. The upper dovetail structure 116 is shown as a protruding dovetail structure, and the lower dovetail structure 125 is shown as a recessed dovetail structure. The upper dovetail structure 116 and the lower dovetail structure 125 are configured to be engageable with each other so as to mate the upper cover 11 with the lower cover 12. This method of assembly is convenient and facilitates a firm connection. Certainly, those skilled in the art will understand that the assembly of the upper cover with the lower cover is not limited to using a dovetail structure, and any other suitable method for assembling the upper cover with the lower cover falls within the scope of protection of the present invention.

[0047] In the technical solution of this utility model, a spacer is provided within the packaging box to divide the internal packaging space into multiple cavities, thereby allowing various types of blocks to be stored in one packaging box and greatly improving the consumer user experience. Furthermore, the rounded corners of the lower cover of the packaging box are configured to be larger than the rounded corners of the upper cover of the packaging box so that consumers can easily hold the packaging box with one hand. Furthermore, the design allows the flip cover to be flipped vertically, allowing consumers to easily access the products in the packaging box with one hand, thereby expanding the use scenarios of the packaging box.
