Abstract

This invention provides a cardboard box packing aid that allows users to apply adhesive tape and pack boxes independently. [Solution] The cardboard box packaging aid 10 is formed by bending a single spring wire. It has a recess 14 that curves in the center and opens downwards, and downward pressing parts 13 on both sides of the recess 14, and lateral pressing parts 11 at both ends of the downward pressing parts 13. The cardboard box packaging aid 10 is elastic, and when it is unfolded and placed over the top of a cardboard box, its lateral pressing parts 11 are biased inward to press against the sides of the cardboard box, and the downward pressing parts 13 press against the top of the cardboard box 10, allowing the flap 31 to be properly closed.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, as in Patent Document 1, when putting a parcel in a box body 1 and closing a flap 2, the flap 2 does not close firmly, and it has become more common to paste an adhesive tape while having someone hold down the side of the box body 1 and the flap 2.

Means for Solving the Problems

[0005] It is configured as a cardboard box packing aid including a recess that opens downward, downward pressing portions on both sides of this recess, and side pressing portions at both ends of this downward pressing portion. This cardboard box packing aid has elasticity. When this cardboard box packing aid is expanded and placed over the upper part of the cardboard box, its side pressing portions are biased inward to press the side portions of the cardboard box inward, and its downward pressing portions press the upper part of the cardboard box downward. A cardboard box packing aid characterized by this.

[0006] The above cardboard box packing aid is characterized by being composed of a single spring wire.

[0007] A cardboard box packing aid characterized by having a clearance between the downward pressing part and the lateral pressing part of the cardboard box packing aid described above. [Effects of the Invention]

[0008] To solve the above problems, we provide a cardboard box packing aid that allows users to apply adhesive tape and pack boxes independently. [Brief explanation of the drawing]

[0009] [Figure 1] This is a perspective view showing the usage state of the cardboard box packing aid according to the first embodiment. [Figure 2] This is a front view (view A) of the cardboard box packing aid of the first embodiment attached to a large cardboard box. [Figure 3] This is a front view showing the cardboard box packing aid of the first embodiment attached to a small cardboard box. [Figure 4] This is a front view of the free-standing state of the cardboard box packing aid according to the first embodiment. [Figure 5] This is a front view of the free-standing state of the cardboard box packing aid according to the second embodiment. [Figure 6] This is a six-view drawing of the cardboard box packing aid of the first embodiment attached to a small cardboard box. The rear view is shown identically to the front view. The left side view is shown identically to the right side view. [Modes for carrying out the invention]

[0010] Figures 1, 2, 3, and 4 illustrate the first embodiment of the cardboard box packaging aid 10. The cardboard box packaging aid 10 is formed by bending a single spring wire. It has a recess 14 that curves in the center and opens downward, and downward pressing portions 13 on both sides of the recess 14, and lateral pressing portions 11 at both ends thereof. This cardboard box packing aid is elastic, and when it is unfolded and placed over the top of a cardboard box, its lateral pressing portion 11 is biased inward to press against the side of the cardboard box, and its downward pressing portion 13 can press against the flap 31 which is the top of the cardboard box 10.

[0011] The flap 31 of the cardboard box 30 tends to open upward due to the rigidity of the cardboard box 30, but the downward pressing part 13 presses the flap 31 downward, allowing the flap 31 to be closed. Furthermore, when items were placed in the cardboard box 30, the internal pressure pushed the sides of the cardboard box outward, causing the abutment portion 32 of the flap 31 to open. However, the lateral pressing portion 11 presses the sides inward, thereby closing the abutment portion 32.

[0012] Since the cardboard box packing aid 10 is elastic, it can be applied flexibly to both large boxes, as shown in Figure 2, and small boxes, as shown in Figure 3.

[0013] Furthermore, the space between the upper pressing portion 13 and the lateral pressing portion 11 is not made in close contact with the cardboard box 30, but rather a gap is left to create a clearance portion 12. This is to ensure that both the upper pressing portion 13 and the lateral pressing portion 11 can simultaneously make close contact with the cardboard box 30, regardless of whether the box is large or small.

[0014] As shown in Figure 1, the cardboard box packaging aid 10 can be used to securely close the flap 31, and the adhesive tape 20 can be independently applied by passing it through the insertion space 15 in the direction of the arrow. The lateral pressing portion 11 is covered with a cap made of a high-friction material to ensure safety and prevent slippage.

[0015] The second embodiment of the cardboard box packaging aid 10 shown in Figure 2 is a cardboard box packaging aid 10 that has a rotating shaft 16 in the center and is biased by a spring 17. [Industrial applicability]

[0016] The present invention relates to a corrugated box packaging aid, which can be used not only for corrugated boxes but also for boxes made of cardboard or plastic.
