Description

Technical Field

[0001] This invention belongs to the field of corrugated cardboard boxes, and particularly relates to a corrugated cardboard box. Background Technology

[0002] Nutritional supplements are mostly in powder form. Currently, they are packaged in plastic bottles and cardboard boxes. Some powdered nutritional supplements need to be mixed with other powdered nutritional supplements or seasonings and diluted with water. Different powdered nutritional supplements are packaged separately and need to be poured into the same cup, diluted with water, and stirred evenly with a tool, which is inconvenient to use.

[0003] In addition, the direction of the corrugated corrugations in corrugated cardboard boxes used for packaging is related to the use of the corrugated cardboard boxes. Generally, the corrugated cardboard used for corrugated cardboard boxes is bent along the corrugations, which makes it easier to bend into a box. Conventional corrugated cardboard boxes are placed vertically, with the vertical direction aligned with the length of the corrugations. This makes the cardboard box less prone to deformation when placed vertically. Therefore, when designing corrugated cardboard boxes, it is necessary to consider the correspondence between the direction of the corrugations and the orientation of the box.

[0004] This invention designs a corrugated cardboard box that can dispense two powdered nutritional products while simultaneously controlling the amount of powder dispensed, the powder dispensing ratio, and the degree of premixing of the two nutritional products. Furthermore, the design of the spatial layout of this invention fully considers the efficient use of space. Summary of the Invention

[0005] To address the aforementioned deficiencies in the prior art, this invention discloses a corrugated cardboard box, which is implemented using the following technical solution.

[0006] A corrugated cardboard box for the outer packaging of powdered nutritional products includes a box body and two vertically distributed mixing mechanisms inside the box body. The box body is characterized in that: the box body is formed by folding and bonding corrugated cardboard with a five-layer structure; two pairs of large boards and two pairs of small boards of the box body are located on two side walls; the top view of the corrugated structure in the two pairs of large boards and two side boards of the box body is wavy.

[0007] The cardboard includes sideboards, middleboards, and corrugated paper, wherein the middleboard is located between two surface sideboards, and corrugated paper is bonded between each sideboard and the middleboard; the bonding strength of the corrugations in the corrugated paper with the sideboards and the middleboard is distributed in a strong-weak-weak-strong-weak-weak pattern.

[0008] The mixing mechanism includes a powder box, a discharge pipe A, a guide sleeve, a connecting pipe, a discharge pipe B, a slide plug, and a return spring. Two connecting pipes connected to the guide sleeve are sealed and nested with the lower discharge pipes A of two powder boxes symmetrically spaced horizontally. The lower end of the guide sleeve has a discharge pipe B connected to it. A slide plug is slidably sealed inside the guide sleeve along the distribution direction of the two powder boxes, and two return springs are installed to reset the slide plug. The slide plug has a structure that allows the two connecting pipes to alternately connect with the discharge pipe B manually and can simultaneously close both connecting pipes.

[0009] As a further improvement to this technology, a lever is installed on the slide plug. The lever slides in the groove on the side wall of the guide sleeve and is located in the space between the two corresponding powder boxes. The lever corresponds to the operating port on the top or bottom plate of the box body for easy operation.

[0010] As a further improvement to this technology, a sealing paper A is installed at the operating opening on the top or bottom plate of the box by adhesive bonding.

[0011] As a further improvement to this technology, the discharge pipe B is located in the space between the two powder boxes in the relative mixing mechanism and is opposite to the discharge port A on the top or bottom plate of the box.

[0012] As a further improvement to this technology, a sealing paper B is installed at the discharge port A on the top or bottom plate of the box by adhesive bonding.

[0013] As a further improvement to this technology, a cap is installed at the end of the discharge pipe B.

[0014] As a further improvement to this technology, the powder box is made of paper with an inner lining.

[0015] As a further improvement to this technology, the discharge pipe A and the connecting pipe are nested and sealed together by adhesive bonding.

[0016] As a further improvement to this technology, the connecting pipe and the corresponding powder box are connected by a sloped transition that facilitates the falling of powder.

[0017] As a further improvement to this technology, the guide sleeve, connecting tube, and discharge tube B are made of polymer plastic.

[0018] The side adhesive strips of the cardboard that is folded to form the box body are connected to the side panels of the box body by adhesive.

[0019] Compared to traditional corrugated cardboard boxes, the five-layer structure within the cardboard forming the box body in this invention includes two layers of corrugated paper, with the corrugated paper positioned vertically along its fold lines, thus ensuring sufficient strength when the box body is vertical. Simultaneously, the bonding method of the two corrugated paper layers within the five-layer cardboard structure allows the cardboard to be effectively bent along fold lines perpendicular to the corrugated paper's fold lines, enabling the cardboard to be folded around a horizontal fold centerline to form the two side panels, top panel, and bottom panel of the box.

[0020] The two mixing mechanisms in this invention are symmetrically distributed along the upper and lower axes, effectively utilizing the space inside the box to hold a sufficient amount of finished powdered nutritional products.

[0021] In this invention, each mixing mechanism can simultaneously pour two powdered nutrients into a cup at the required mixing ratio, thereby improving the mixing efficiency of different powdered nutrients.

[0022] This invention has a simple structure and good performance. Attached Figure Description

Detailed Implementation

[0035] The accompanying drawings are schematic diagrams illustrating embodiments of the present invention to facilitate understanding of the structural operating principle. Specific product structures and dimensions can be determined based on the usage environment and conventional technologies.

[0036] like Figure 1 , 2 As shown, this embodiment of the invention provides a corrugated cardboard box for the outer packaging of powdered nutritional products. It includes a box body 100 and two vertically distributed mixing mechanisms 200 within the box body 100. Figure 9 , 10 As shown, the box body 100 is formed by folding and bonding corrugated cardboard with a five-layer structure; the two pairs of large panels 108 and two pairs of small panels 107 of the box body 100 are located on the two side walls; the top view of the corrugated structure in the two pairs of large panels 108 and the two side panels 101 of the box body 100 is wavy. Figure 11 As shown, the structure of box 100 can effectively improve its strength.

[0037] like Figure 11 As shown, the cardboard includes side panels 109, a middle panel 110, and corrugated paper 111. The middle panel 110 is located between the two surface side panels 109. Corrugated paper 111 is bonded between each side panel 109 and the middle panel 110. The bonding strength of the corrugations in the corrugated paper 111 to the side panels 109 and the middle panel 110 at the bonding points 112 follows a pattern of strong, weak, weak, strong, weak, weak. The cardboard structure effectively improves the strength of the box 100 and facilitates effective bending when the cardboard is folded into the box 100.

[0038] like Figure 5 As shown, the mixing mechanism 200 includes a powder box 201, a discharge pipe A 202, a guide sleeve 203, a connecting pipe 204, a discharge pipe B 206, a sliding plug 208, and a return spring 210, wherein... Figure 3 , 6As shown in Figure 7, the two connecting pipes 204 on the guide sleeve 203 are connected to the lower discharge pipes A202 of the two powder boxes 201 that are symmetrically spaced along the horizontal direction and are sealed and nested together; the lower end of the guide sleeve 203 has a discharge pipe B206 connected to it; as shown in Figure 7. Figure 3 , 4 As shown in Figure 8, a sliding plug 208 is sealed and slidable inside the guide sleeve 203 along the distribution direction of the two powder boxes 201, and two reset springs 210 are installed to reset the sliding plug 208; the sliding plug 208 has a structure that allows the two connecting pipes 204 to be alternately connected to the discharge pipe B206 by manual means and can simultaneously close the two connecting pipes 204.

[0039] In one embodiment, such as Figure 3 , 4 As shown in Figure 8, a lever 211 is installed on the slide plug 208. The lever 211 slides in the groove 205 on the side wall of the guide sleeve 203 and is located in the space between the two powder boxes 201. The lever 211 corresponds to the operation port 105 on the top plate 102 or bottom plate 106 of the box body 100, which facilitates the operation of the lever 211.

[0040] In one embodiment, such as Figure 1 , 9 As shown, a sealing paper A113 is installed at the operation port 105 on the top plate 102 or bottom plate 106 of the box body 100 by adhesive.

[0041] In one embodiment, such as Figure 2 , 3 As shown, the discharge pipe B206 is located in the space between the two powder boxes 201 in the relative mixing mechanism 200 and is opposite to the discharge port A104 on the top plate 102 or bottom plate 106 of the box body 100.

[0042] In one embodiment, such as Figure 1 , 9 As shown, a sealing paper B114 is installed at the discharge port A104 on the top plate 102 or bottom plate 106 of the box body 100 by adhesive.

[0043] In one embodiment, such as Figure 3 As shown, a cap 207 is installed at the end of the discharge pipe B206.

[0044] In one embodiment, such as Figure 5 As shown, the powder box 201 is made of paper with an inner lining.

[0045] In one embodiment, such as Figure 3 As shown, the discharge pipe A202 and the connecting pipe 204 are nested and sealed together by adhesive.

[0046] In one embodiment, such as Figure 6 As shown, the connecting pipe 204 and the corresponding powder box 201 are connected by a slope that facilitates the falling of powder.

[0047] In one embodiment, such as Figure 7 As shown, the guide sleeve 203, connecting pipe 204 and discharge pipe B206 are made of polymer plastic.

[0048] In this invention, the side end adhesive strip 103 of the cardboard used to fold and form the box body 100 is connected to the side plate 101 of the box body 100 by adhesive.

[0049] In this invention, each of the two powder boxes 201 in each mixing mechanism 200 can be filled with two kinds of powdered nutrients that need to be mixed or discharged separately. That is, the four powder boxes 201 in the two mixing mechanisms 200 can be filled with four kinds of powdered nutrients. The two kinds of powdered nutrients in the two powder boxes 201 in each mixing mechanism 200 can be poured out according to the required ratio.

[0050] In this invention, the two powder boxes 201 in each mixing mechanism 200 are glued to the top plate 102 or bottom plate 106 of the box body 100.

[0051] The working process of the present invention is as follows: In the initial state, the slide plug 208 in each mixing mechanism 200 closes the discharge pipe A202 at the bottom of the corresponding two powder boxes 201, the corresponding two return springs 210 are in a compressed state, and the two discharge ports B209 on the slide plug 208 are located between the corresponding two connecting pipes 204.

[0052] When it is necessary to use the present invention to pour two powdered nutrients into a cup in the required proportion, first place the discharge port A104 on the bottom plate 106 or top plate 102 corresponding to the mixing mechanism 200 of the two powdered nutrients to be poured out at the bottom and use two supports to suspend the box 100 so that the cup can be placed directly below the discharge port A104.

[0053] Then, remove the sealing paper B114 at the bottom outlet A104 and remove the cap 207 at the end of the outlet pipe B206.

[0054] Next, remove the sealing paper A113 at the top operating port 105.

[0055] Then, the lever 211 is moved back and forth from the operating port 105 according to the required ratio of the two nutrients. The lever 211 drives the slide plug 208 to move back and forth, so that the two discharge ports B209 on the slide plug 208 switch the discharge pipes A202 at the bottom of the two powder boxes 201 back and forth. At the same time, the two return springs 210 deform back and forth.

[0056] When one outlet B209 on the slide stopper 208 is opposite to the bottom outlet pipe A202 of a powder box 201, the nutrients in the corresponding powder box 201 are discharged into the cup through the outlet pipe A202, outlet B209 and outlet pipe B206. At the same time, the outlet pipe A202 on the slide stopper 208 that is opposite to the bottom of another powder box 201 is closed.

[0057] In summary, the beneficial effects of the present invention are as follows: the five-layer structure within the cardboard forming the box body 100 of the present invention includes two layers of corrugated paper 111, and the corrugated paper 111 is in a vertical state along its fold line, thereby ensuring that the box body 100 has sufficient strength when vertical. At the same time, the bonding method of the two layers of corrugated paper 111 within the five-layer structure cardboard forming the box body 100 allows the cardboard to be effectively bent along a fold line perpendicular to the fold line of the corrugated paper 111, thereby folding the cardboard around the horizontal fold center line to form the two side panels 101, top panel 102, and bottom panel 106 of the carton.

[0058] The two mixing mechanisms 200 in this invention are symmetrically distributed along the upper and lower axes, effectively utilizing the internal space of the box 100 to hold a sufficient amount of finished powdered nutritional products.

[0059] In this invention, each mixing mechanism 200 can simultaneously pour two powdered nutrients into a cup at the required mixing ratio, thereby improving the mixing efficiency of different powdered nutrients.
