Description

Technical Field

[0001] This utility model relates to the technical field of paper boxes, and in particular to a snap-fit ​​paper box. Background Technology

[0002] Folding cartons are a widely used packaging container, typically made of cardboard, corrugated cardboard, or specialty paper, with a thickness between 0.3 mm and 1 mm. Through precise die-cutting and creasing processes, fold lines, interlocking folds, and other structures are formed on the cardboard, allowing for assembly with little or no connection. They are shipped as single, flat pieces of cardboard, saving transportation and storage space. Users can quickly assemble them into boxes using folding and interlocking techniques.

[0003] However, most existing cardboard boxes on the market have a chamber structure, meaning that after the cardboard is folded from a single flat piece of cardboard into a box structure, there is only a single chamber inside for storing items. However, this single-chamber cardboard box has certain limitations in practical use. For example, in the catering industry, it is common to provide bagged or boxed condiments such as soy sauce. Such single-chamber cardboard boxes can only hold food and condiment containers together. This can affect food hygiene and makes it easy to miss the condiment containers. Therefore, to address these shortcomings, this application proposes a snap-fit ​​cardboard box with two chambers. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a snap-fit ​​paper box with two chambers for storing food and condiment boxes respectively.

[0005] The objective of this utility model is achieved through the following technical solution: A snap-fit ​​cardboard box, comprising: The main box has a first inner cavity and a side hole on one outer wall.

[0019] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0020] like Figure 1As shown, a snap-fit ​​paper box 10 includes a main box 100, an inner box 200, and a paper cover 300. The main box 100 has a first inner cavity and a side hole 101 on one side outer wall. The inner box 200 is disposed on the inner side wall of the main box 100 and has a second inner cavity, which communicates with the side hole 101. The paper cover 300 is disposed on one side of the main box 100 and is used to snap-fit ​​to cover the first inner cavity and the second inner cavity.

[0021] It should be noted that when the main box 100 is placed upright, the inner box 200 is located on the left or right inner wall of the first inner cavity of the main box 100, and the paper lid 300 is located on the rear side of the main box 100. Thus, when the paper lid 300 is under force, it can be fastened to the top of the main box 100 to cover the first and second inner cavities. Food can then be placed in the first inner cavity. After the paper lid 300 is fastened and fixed, it is possible to visually observe whether the seasoning box has been placed inside through the side hole 101. If the seasoning box is not placed inside, it can be quickly inserted into the second inner cavity through the side hole 101. Thus, the snap-fit ​​cardboard box 10 of this application has an independent first inner cavity and a second inner cavity, which allows food and seasoning boxes to be stored separately. Secondly, the side hole 101 can quickly determine whether a seasoning box has been left out, and the side hole 101 can quickly insert the seasoning box into the second inner cavity. Compared with the single-chamber cardboard box in the prior art, the snap-fit ​​cardboard box 10 of this application is more convenient to use.

[0022] like Figures 1 to 8 As shown, in one embodiment, the main box 100 includes two longitudinal paper blocks 110, two lateral paper blocks 120, two longitudinal bottom paper blocks 130, and two lateral bottom paper blocks 140. The two longitudinal paper blocks 110 and the two lateral paper blocks 120 are connected in an alternating manner. The two longitudinal bottom paper blocks 130 are respectively disposed on the bottom side edges of the two longitudinal paper blocks 110, and the two lateral bottom paper blocks 140 are respectively disposed on the bottom side edges of the two lateral paper blocks 120. The lateral paper blocks 120 located at the end are used to connect with the longitudinal paper blocks located at the beginning. Blocks 110 are connected so that two longitudinal paper blocks 110 and two lateral paper blocks 120 form a rectangular box. One adjacent longitudinal bottom paper block 130 and one adjacent side bottom paper block 140 are glued to each other, and another adjacent longitudinal bottom paper block 130 and one adjacent side bottom paper block 140 are glued to each other. The two longitudinal bottom paper blocks 130 are interlocked to form the main box 100. The paper cover 300 is provided on the top side of the longitudinal paper block 110 at the first end, and the side hole 101 is opened on the lateral paper block 120 at the end.

[0023] It should be noted that the first vertical paper block 110 is set as the beginning position. The first lateral paper block 120 is connected to the first vertical paper block 110. Then, the second vertical paper block 110 is connected to the first lateral paper block 120, and then the second lateral paper block 120 is connected to the second vertical paper block 110. In this way, the two vertical paper blocks 110 and the two lateral paper blocks 120 are connected alternately. Thus, the first vertical paper block 110 becomes the beginning position, and the last connected second lateral paper block 120 becomes the end position. The second lateral paper block 120 at the end position is connected to the first vertical paper block 110 at the beginning position, so that the two vertical paper blocks 110 and the two lateral paper blocks 120 form an enclosed rectangular box structure. At this time, the two bottom vertical paper blocks 130 and the two bottom side paper blocks 140 are arranged adjacently in sequence. In this embodiment, two adjacent vertical bottom paper blocks 130 and 140 are bonded together, and another adjacent vertical bottom paper block 130 and 140 are bonded together. In this application, the vertical bottom paper block 130 located at the bottom edge of the first vertical paper block 110 and the 140 located at the bottom edge of the last lateral paper block 120 are bonded together. Additionally, the vertical bottom paper block 130 located at the bottom edge of the first vertical paper block 110 (i.e., in the middle position) and the 140 located at the bottom edge of the last lateral paper block 120 are bonded together as an example for illustration. It should be noted that any adjacent vertical paper blocks 110 and lateral paper blocks 120 are perpendicular to each other, while the vertical bottom paper blocks 130 and lateral bottom paper blocks 140 need to jointly form the bottom of the main box 100. Therefore, the vertical bottom paper blocks 130 and lateral bottom paper blocks 140 are glued together and overlapped. At this time, the two vertical bottom paper blocks 130 forming the main box are in a structure facing each other, and the two vertical bottom paper blocks 130 interlock with each other, thus forming a solid bottom structure of the main box 100.

[0024] like Figure 2 As shown, in one embodiment, the vertical bottom paper block 130 includes a main paper block 131 and a folded paper block 132 connected to each other. The main paper block 131 is disposed on the bottom side of the vertical paper block 110, and the folded paper block 132 is used to bond with the side bottom paper block 140.

[0025] It should be noted that the structure of this embodiment is designed to facilitate the folding of the main box 100 into a flat structure. Specifically, the vertical bottom paper block 130 and the side bottom paper block 140, which are glued and fixed to each other, are planar structures. This planar structure would hinder the folding of the vertical paper block 110 and the side paper block 120 at the corresponding positions. Therefore, to avoid this problem, the vertical bottom paper block 130 is designed to be a structure in which the main paper block 131 and the folding paper block 132 are connected to each other. There is a fold line (a crease, indicated by a dashed line in the figure) between the main paper block 131 and the folding paper block 132. Thus, when folding is required, an inward pushing force is applied to the crease between the main paper block 131 and the folding paper block 132, so that the main paper block 131 and the folding paper block 132 fold to each other (since the folding paper block 132 is glued and fixed to the side bottom paper block 140, it can also be described as the main paper block 131 and the side bottom paper block 140 folding to each other), while the vertical paper block 110 and the side paper block 120 fold simultaneously. In this way, the main box 100 can be transformed from a rectangular structure into a parallelogram structure, and finally folded into a flat structure (from a top or bottom view). This foldable design facilitates transportation and storage.

[0026] like Figure 2 , Figure 8 , Figure 9 As shown, in one embodiment, a locking step 1311 is provided on the bottom side of the main paper block 131, and the locking steps 1311 of the two main paper blocks 131 are used to interlock and lock each other.

[0027] It should be noted that, through the locking step 1311, the main paper block 131 is roughly divided into two parts with the locking step 1311 as the dividing line. The part connected to the folded paper block 132 is defined as the exposed part, and the other part not connected to the folded paper block 132 is defined as the internal part. In this way, the two main paper blocks 131 are divided into two exposed parts and two internal parts respectively with the locking step 1311. For ease of description, the parts on one main paper block 131 are defined as exposed part A1 and internal part B1, and the parts on the other main paper block 131 are defined as exposed part A2 and internal part B2. Thus, through the locking step 1311, the internal part B1 overlaps with the inside of the exposed part A2, and the internal part B2 overlaps with the inner wall of the exposed part A1. In this way, the two main paper blocks 131 are locked and fixed by the two locking steps 1311.

[0028] like Figure 1 , Figure 2 As shown, in one embodiment, the main box 100 also includes two side top paper blocks 150, which are respectively disposed on the top side edges of the two side paper blocks 120. When the paper cover 300 is fastened, the paper cover 300 abuts against the two side top paper blocks 150.

[0029] It should be noted that the two side top paper blocks 150 abut against the paper cover 300, which can eliminate the gap between the side paper blocks 120 and the paper cover 300, improve the airtightness of the first inner cavity, and prevent dust and other debris from entering through the gap between the paper cover 300 and the side paper blocks 120.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the paper cover 300 includes a cover block 310 and a fastener 320 connected to each other. The cover block 310 is disposed on the top side of the longitudinal paper block 110 located at the first end, and the fastener 320 is used to engage with the longitudinal paper block 110 located away from the first end.

[0031] It should be noted that the buckle 320 and the cover 310 are folded over each other. The buckle 320 is connected to the top side of one of the two longitudinal paper blocks 110, and the buckle 320 is engaged and fixed with the top side of the other longitudinal paper block 110, so that the paper cover 300 can be stably fastened to the main box 100.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the fastener 320 is provided with a locking protrusion 321, and the longitudinal paper block 110 away from the first end is provided with a locking groove 111. The locking protrusion 321 is used to insert into the locking groove 111 so that the fastener 320 is engaged with the longitudinal paper block 110 away from the first end. In this way, the locking protrusion 321 is inserted into the locking groove 111, and can be locked and fixed, so that the paper cover 300 is fastened and fixed on the main box 100.

[0033] like Figures 1 to 5 As shown, in one embodiment, the inner box 200 includes an inner adhesive paper block 210, a transverse paper block 220, an end adhesive paper block 230, a material-carrying paper block 240, and two inner top paper blocks 250. The inner adhesive paper block 210, the transverse paper block 220, and the end adhesive paper block 230 are connected in sequence, and the inner adhesive paper block 210 is connected to the lateral paper block 120 located at the end. The inner adhesive paper block 210 is used to adhere to the longitudinal paper block 110 located at the beginning, and the end adhesive paper block 230 is used to... The load paper block 240 is bonded to the longitudinal paper block 110 away from the beginning end, and the bottom side of the transverse paper block 220 is connected. When the load paper block 240 is folded at a right angle relative to the transverse paper block 220, a portion of the structure of the load paper block 240 is inserted into the side hole 101. Two inner top paper blocks 250 are connected to the bottom side of the load paper block 240 at intervals. The two inner top paper blocks 250 are used to abut against the lateral paper block 120 located at the end.

[0034] It should be noted that the inner adhesive paper block 210 is connected to the lateral paper block 120 at the end of the main box 100. Thus, the first longitudinal paper block 110, the first lateral paper block 120, the second longitudinal paper block 110, the second lateral paper block 120, the inner adhesive paper block 210, the transverse paper block 220, and the end adhesive paper block 230 are connected sequentially. In this way, the main box 100, the inner box 200, and the paper cover 300 can be cut and shaped from a single support plate, and then creases are pressed along the dotted lines to form a snap-fit ​​paper box 10 with a first inner cavity and a second inner cavity. The inner adhesive paper block 210 is used to adhere and fix it to the longitudinal paper block 110 located at the beginning. The end adhesive paper block 230 is used to adhere and fix it to the longitudinal paper block 110 located at a position other than the beginning. Thus, pressing part of the material-carrying paper block 240 into the side hole 101 forms the second inner cavity. The seasoning box can then be inserted into the second inner cavity through the side hole 101.

[0035] like Figure 1 As shown, in one embodiment, the length of the transverse paper block 220 is the same as the length of the lateral paper block 120.

[0036] In this way, the second inner cavity also forms a rectangular structure (viewed from above or below). Thus, after the material carrier 240 is folded over to overlap with the transverse paper 220, as the main box 100 is folded, the second inner cavity will also change from a rectangle to a parallelogram. Finally, the inner box 200 follows the folding of the main box 100 to form a flat structure.

[0037] like Figure 2 As shown, in one embodiment, a paper-blocking block 102 is respectively provided on the two opposing inner walls of the side hole 101.

[0038] It should be noted that the baffle paper block 102 has a free structure at one end. In this way, by using two baffle paper blocks 102 to block the seasoning box in the second inner cavity, the seasoning box can be stably stored in the second inner cavity and prevented from accidentally sliding out.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products.
