Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box processing technology, specifically to a small box with an automatically formed inner grid. Background Technology
[0002] Paper boxes are a widely used packaging medium in modern life, and their sizes range from large transport packaging to micro pharmaceutical packaging.
[0003] Among existing packaging boxes, there is a type of box with an inner grid, which is formed by folding and pasting a whole sheet of paper. In the forming process of this type of box, since the inner grid cannot be automatically stretched and formed, a secondary operation is required, either manually or by machine, to complete the forming of the inner grid, resulting in low production efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a small box with an automatically formed internal grid, which can directly stretch and form the grid strips of the paper box.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:
[0006] A small box with an automatically formed inner grid includes cardboard for folding and pasting to form the box. The cardboard includes an outer box surface for forming the outer box body and an inner box surface for forming the inner grid. The inner box surface includes an inner left box surface, an inner main box surface, an inner right box surface, an inner rear box surface, a partition surface, and an adhesive surface. The cardboard has an opening that spans the inner rear box surface and the partition surface. The opening includes a first opening on the inner rear box surface and a second opening on the partition surface. The area directly above the opening is a grid strip. A first adhesive section is provided between the grid strip and the adhesive surface. A slit connected to the opening is provided below the first adhesive section. The surface on the cardboard between the first adhesive sections is the front side. The back side of the cardboard has a second adhesive section below the first opening. The first adhesive section and the adhesive surface are adhered to the front side of the inner main box surface, and the second adhesive section is adhered to the front side of the outer main box surface. Its function is to bond and fix the two ends of the grid strip by setting the first adhesive section and the second adhesive section respectively, so that when the cardboard box is stretched open, the grid strip can be formed into place to separate the space enclosed by the partition plate, the inner main box surface, the inner right box surface and the inner rear box surface.
[0007] Furthermore, the outer box surface includes an outer left box surface, an outer main box surface, an outer right box surface, and an outer rear box surface. The cardboard includes an outer left box surface, an outer main box surface, an outer right box surface, an outer rear box surface, an inner left box surface, an inner main box surface, an inner right box surface, an inner rear box surface, a dividing surface, and an adhesive surface, which are sequentially separated along the width direction of the cardboard by fold lines. Its function is that, by setting the fold lines, each surface is divided along the fold lines before the pasting step, so that the entire small box can be formed by relying on the pre-folded marks along the fold lines during the stretching step.
[0008] Furthermore, fold lines are provided between the grid strip and the inner rear box surface, as well as between the grid strip and the partition surface. The purpose of these fold lines is to facilitate the stretching and shaping of the grid strip.
[0009] Furthermore, the width a1 of the outer left box surface and the width a2 of the outer right box surface are equal, and the width a3 of the inner left box surface and the width a4 of the inner right box surface are equal, with the width a1 of the outer left box surface being greater than the width a3 of the inner left box surface. This arrangement ensures that the dimensional relationship between the outer and inner left box surfaces provides sufficient space for accommodating the product within the cavities formed by the outer and inner box surfaces.
[0010] Furthermore, the width a5 of the grid strip is equal to the width a4 of the inner right box surface, and the width a6 of the first adhesive section is equal to the width a7 of the first opening. This design ensures that the stretched grid is parallel to both the dividing surface and the inner right box surface, through the dimensional relationship between the grid strip and the inner left box surface, and between the first adhesive section and the first opening.
[0011] Furthermore, at least one left-side adhesive area is provided between the back of the inner left box surface and the inner layer of the outer left box surface, and at least one right-side adhesive area is provided between the back of the inner right box surface and the front of the outer right box surface. This serves to securely connect the left and right sides of the inner and outer boxes through the provision of the left and right adhesive areas.
[0012] Furthermore, the width a8 of the inner main box surface is greater than the sum of the width a9 of the inner rear box surface and the width a10 of the adhesive surface. This design ensures that the adhesive surface can be completely bonded within the inner main box surface through the dimensional relationship between the inner main box surface, the inner rear box surface, and the adhesive surface.
[0013] Furthermore, a front adhesive area is provided between the front surface of the inner main box and the adhesive surface. After the inner box is folded and pasted, the first adhesive section is located on the side of the inner main box away from the inner left box.
[0014] Furthermore, the bottom height of the inner left box surface gradually increases in the direction away from the outer rear box surface. This design prevents the inner left box surface from pressing against the bottom surface of the small box during its molding process.
[0015] Furthermore, the bottom height of the inner right box surface gradually increases in the direction away from the inner main box surface. This design prevents the inner right box surface from pressing against the bottom surface of the small box during its molding process.
[0016] The beneficial effects of this utility model are:
[0017] 1. By setting the first and second adhesive sections, the two ends of the grid strip can be glued and fixed respectively. When the cardboard box is stretched open, the grid strip can be directly formed into place to separate the space enclosed by the partition plate, the inner main box surface, the inner right box surface, and the inner rear box surface.
[0018] 2. By setting fold lines, the various surfaces are divided by folding along the fold lines before the pasting step, so that the whole box can be formed by relying on the pre-folded marks along the fold lines during the stretching step. Attached Figure Description

[0026] Example 1
[0027] A small box with an internal grid that is automatically formed, such as Figure 1 As shown, the cardboard includes cardboard for folding and pasting to form a paper box. The cardboard includes an outer box surface for forming the outer box body and an inner box surface for forming the inner cardboard grid. The inner box surface includes an inner left box surface 1, an inner main box surface 2, an inner right box surface 3, an inner rear box surface 4, a partition surface 5, and an adhesive surface 6. The cardboard has an opening 7 spanning the inner rear box surface 4 and the partition surface 5. The opening 7 includes a first opening 701 located on the inner rear box surface 4 and a second opening 702 located within the partition surface 5. The area directly above the opening 7 is a grid strip 8. A first adhesive section 9 is provided between the grid strip 8 and the adhesive surface 6. Below the first adhesive section 9 is a slit 10 communicating with the opening 7. The surface of the cardboard between the first adhesive sections 9 is the front side. Figure 2 As shown, a second adhesive section 11 is provided on the back of the cardboard below the first opening 701. The first adhesive section 9 and the adhesive surface 6 are adhered to the front of the inner main box surface 2, and the second adhesive section 11 is adhered to the front of the outer main box surface 13. Its function is that, through the setting of the first adhesive section 9 and the second adhesive section 11, the two ends of the grid strip 8 can be glued and fixed respectively. When the cardboard box is stretched open, the grid strip 8 can be directly formed into place to separate the space enclosed by the partition plate, the inner main box surface 2, the inner right box surface 3, and the inner rear box surface 4.
[0028] Specifically, such as Figure 1 As shown, the outer box surface includes an outer left box surface 12, an outer main box surface 13, an outer right box surface 14, and an outer rear box surface 15. The cardboard includes an outer left box surface 12, an outer main box surface 13, an outer right box surface 14, an outer rear box surface 15, an inner left box surface 1, an inner main box surface 2, an inner right box surface 3, an inner rear box surface 4, a dividing surface 5, and an adhesive surface 6, which are sequentially separated along the folding lines 16 before the pasting step. Its function is that, by setting the folding lines 16, the various surfaces are folded and divided along the folding lines 16 before the pasting step, so that the entire small box can be formed by relying on the pre-folded marks along the folding lines 16 during the stretching step.
[0029] Specifically, such as Figure 1As shown, fold lines 16 are provided between the grid strip 8 and the inner rear box surface 4, and between the grid strip 8 and the partition surface 5. The function of these fold lines 16 is to facilitate the stretching and shaping of the grid strip 8.
[0030] Specifically, such as Figure 1 As shown, the width a1 of the outer left box surface 12 and the width a2 of the outer right box surface 14 are equal, and the width a3 of the inner left box surface 1 and the width a4 of the inner right box surface 3 are equal. The width a1 of the outer left box surface 12 is greater than the width a3 of the inner left box surface 1. This arrangement ensures that the dimensional relationship between the outer left box surface 12 and the inner left box surface 1 provides a gap for accommodating the product within the cavity formed by the outer and inner box surfaces.
[0031] Specifically, such as Figure 1 As shown, the width a5 of the grid strip 8 is equal to the width a4 of the inner right box surface 3, and the width a6 of the first adhesive section 9 is equal to the width a7 of the first opening 701. Its function is to ensure that, through the design of the dimensional relationship between the grid strip 8 and the inner left box surface 1, and the dimensional relationship between the first adhesive section 9 and the first opening 701, the stretched grid is parallel to both the partition surface 5 and the inner right box surface 3.
[0032] Specifically, such as Figure 2 As shown, at least one left-side adhesive area 17 is provided between the back of the inner left box surface 1 and the inner layer of the outer left box surface 12, and at least one right-side adhesive area 18 is provided between the back of the inner right box surface 3 and the front of the outer right box surface 14. The back of the inner left box surface 1 has two left-side adhesive areas 17, and the back of the inner right box surface 3 has two right-side adhesive areas 18. Their function is to securely connect the left and right sides of the inner and outer boxes through the provision of the left-side adhesive areas 17 and right-side adhesive areas 18.
[0033] Specifically, such as Figure 1 As shown, the width a8 of the inner main box surface 2 is greater than the sum of the width a9 of the inner rear box surface 4 and the width a10 of the adhesive surface 6. Its function is that, through the design of the dimensional relationship between the inner main box surface 2, the inner rear box surface 4, and the adhesive surface 6, the adhesive surface 6 can be completely bonded to the inner main box surface 2.
[0034] Specifically, such as Figure 1 As shown, a front adhesive area 19 is provided between the front surface of the inner main box 2 and the adhesive surface 6. When the inner box is folded and pasted, the first adhesive segment 9 is located on the side of the inner main box 2 away from the inner left box 1. The front surface of the main box is provided with a front adhesive area 19.
[0035] Specifically, such as Figure 1As shown, the bottom height of the inner left box surface 1 gradually increases in the direction away from the outer rear box surface 15. Its function is to prevent the inner left box surface 1 from pressing against the bottom surface of the small box during the forming of the small box by designing the bottom shape of the bottom of the inner left box surface 1.
[0036] Specifically, such as Figure 1 As shown, the bottom height of the inner right box surface 3 gradually increases in the direction away from the inner main box surface 2. Its function is to prevent the inner right box surface 3 from pressing against the bottom surface of the small box during the forming of the small box through the design of the bottom shape of the bottom shape of the inner right box surface 3.
[0037] The working principle of this embodiment is explained as follows: First, the cardboard is pre-folded along each fold line 16. Then, glue is applied to the bonding surface 6, the first bonding section 9, the second bonding section 11, the left bonding area 17, the right bonding area 18, and the front bonding area 19. After that, the cardboard is folded and pasted along each fold line 16 into a flat shape.
[0038] In this state, the outer left box surface 12 and the outer rear box surface 15 are located in the first layer, the inner left box surface 1, the inner rear box surface 4, the grid strip 8, the partition surface 5, and the adhesive surface 6 are located in the second layer, the inner main box surface 2 and the inner right box surface 3 are located in the third layer, and the outer main box surface 13 and the outer right box surface 14 are located in the fourth layer.
[0039] Then, the small box is directly stretched and unfolded. Due to the fixation of the left end of the grid strip 8 by the first adhesive section 9 and the fixation of the inner rear box surface 4 near the first opening 701 by the second adhesive section 11, the second grid strip 8 can be directly stretched and formed.
[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
