Description

[Technical Field]

[0001] The present invention relates to a handle that can be inserted into the bottom of an erected cardboard box. [Background technology]

[0002] Previously, in order to carry a cardboard box, one had to lift it by placing one's hands on the corners of the bottom and sides.

[0003] The heavier the goods packed in the cardboard box, the more difficult it becomes to reach the corners of the bottom and sides, which creates a problem in that if the cardboard box is accidentally dropped, the impact becomes stronger, increasing the risk of damaging the goods.

[0006] The invention of Patent Document 1 is a cardboard box with a handle, but it deforms the cardboard and is therefore not practical. Furthermore, the invention of Non-Patent Document 1 involves placing a nylon belt with handles on both ends along the bottom of the cardboard box, passing your hands through the handles, and lifting the cardboard, but the task of placing the belt under the bottom is difficult. The present invention aims to provide a handle that can be inserted into the bottom of an assembled cardboard box, making it easy to lift the assembled cardboard box. [Means for solving the problem]

[0007] (1) The present invention is a handle that can be inserted into the bottom of an assembled cardboard box, characterized in that the handle is L-shaped with sides and a bottom, the tip of the bottom of the handle is at an acute angle, and the side has a hole that serves as a holding portion for inserting the hand, and the tip can be inserted into the bottom of the cardboard box with the underside of the bottom of the handle resting on the ground, making it possible to lift the cardboard box.

[0008] (2) In addition to (1), the present invention is characterized in that a protrusion is provided on the bottom surface of the bottom of the handle where it comes into contact with the bottom surface of the cardboard, so that when the handle is lifted, the protrusion is shaped like a diamond, a wedge, or a triangular pyramid, and further characterized in that the handles are a pair, one on the left and one on the right, with the left handle held in the left hand and the right handle held in the right hand, and the holding portions of each of the left and right handles are inclined so that when inserted into the bottom of an assembled cardboard box, the side of the holding portion facing the body is inclined downward. [Effects of the Invention]

[0009] The handle that can be inserted into the bottom of the assembled cardboard box of the present invention and can be attached and detached has the advantage that the cardboard box can be easily and efficiently transported regardless of the load of the goods packed in it.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The handle 1 of the present invention has a cross section that is approximately L-shaped. That is, as can be seen from FIG. 4, which is a cross section of part B in FIG. 3, the handle 1 is approximately L-shaped. As can be seen from FIG. 6, the upper surface (also called the bottom upper surface) 2 of the bottom portion of the approximately L-shaped surface of the handle 1 is the surface that receives the bottom surface of the cardboard box 12, and the side surface 4 of the approximately L-shaped surface of the handle 1 is the surface that receives the side surface of the cardboard box 12. Therefore, the side surface 4 of the approximately L-shaped surface and the bottom upper surface 2 of the approximately L-shaped surface form an approximately right angle. As can be seen from FIGS. 1 to 7, the lower surface (also called the bottom lower surface) 3 of the bottom portion of the approximately L-shaped surface of the handle 1 intersects with the bottom upper surface 2 of the approximately L-shaped surface at an acute angle, and is shaped to be easily inserted into the bottom of the cardboard box 12 placed on the ground.

[0012] The side portion of the handle 1 (also referred to as the side portion or insertion portion 9) has a hole (also referred to as the holding portion) 5 into which a hand or finger can be inserted (inserted). That is, as shown in FIG. 4, a hand or finger is inserted from the F side of the holding portion 5 and placed on the upper surface 6 of the holding portion (hole) 5 to support the cardboard 12. As mentioned above, the bottom portion of the handle 1 (also referred to as the bottom portion or receiving portion 10 (which receives the bottom of the cardboard 12)) is composed of an upper bottom surface 2 and a lower bottom surface 3, and its tip 11 forms an acute angle. The handle 1 is preferably made of plastic, which is easy to process and mold, but other materials such as wood can also be used. The handle 1 of the present invention shown in FIGS. 1 and 2 is intended for use with the left hand, but there is also a mirror-image handle for use with the right hand, and the handle of the present invention is intended for use with these as a pair.

[0013] The detachable handle 1 shown in Fig. 1 can be inserted into the bottom of a cardboard box. By inserting the bottom surface 3 of the receiving part 10 of the handle 1 into the cardboard box 12 placed on the ground as shown in Fig. 5, and then holding the holding part 5 as shown in Fig. 7, the cardboard box 12 can be lifted. The holding part 5 has a hole for the fingers to fit into.

[0014] As shown in Figure 1, the protrusion 7 attached to the cardboard contact surface (bottom upper surface) 2 of the receiving portion 10 of the handle 1 (which contacts the bottom of the cardboard 12) is a triangular pyramid. This protrusion 7 bites into the bottom surface of the cardboard 12 and tape attached to the bottom surface of the cardboard 12, allowing the cardboard 12 to be held stably. In addition, the protrusion 8 attached to the cardboard contact surface (side of the L-shaped surface) 4 of the insertion portion 9 of the handle 1 (which receives the side of the cardboard 12) is also a triangular pyramid. This protrusion 8 bites into the side of the cardboard 12 and tape attached to the side of the cardboard 12, allowing the cardboard 12 to be held stably. Note that the shapes of the protrusions 7 and 8 may be shapes other than triangular pyramids, such as diamond shapes or wedge shapes, as long as they achieve the above-mentioned purpose.

[0015] As shown in FIG. 2, 3 is the surface (surface forming tip 11) that comes into contact with the ground when inserted and tilts the handle at an angle, and is inclined relative to the cardboard contact surface 2, with tip 11 forming an acute angle. 2, a wedge-shaped receiving portion 10 is formed by the cardboard contact surface (bottom upper surface) 2 and the tip forming surface (bottom lower surface) 3. This allows the handle to be easily inserted into the bottom surface of the cardboard 12.

[0016] As shown in Figure 3, the side of the holding part 5 that faces the body is inclined downward when the cardboard box 12 is lifted. This allows the cardboard box 12 to be pulled towards the body, making it possible to hold the cardboard box 12 stably.

[0017] As shown in the cross-sectional view of Figure 4, the surface 6 of the holding part 5 that comes into contact with the fingers (the upper surface of the holding part 5) is inclined upward toward the cardboard 12. This inclination makes the handle easier to hold.

[0018] As shown in Figure 8, a load (A) acts on the handle, generating a moment load (B) around the holding part 5. This moment load causes the handle to rotate slightly clockwise, causing the cardboard to slide down (C). As this movement occurs, protrusions 7 and 8 bite into the cardboard 12, generating forces (D2) and (D1) respectively, making it possible to hold the cardboard 12 stably.

[0019] As shown in Figure 9, it is possible to hold the cardboard box 12 using the handle 1.

[0020] This invention was produced using a 3D printer (as shown in Figure 9), but the production method can also be realized by pressing metal plates. A handle with surfaces 2, 3, and 4, holding part 5, and protrusions 7 and 8 can be produced that can be inserted into cardboard in the same way. [Industrial Applicability]

[0021] When transporting an assembled cardboard box, not only will it be easier to carry regardless of the weight of the contents, but it is also expected to reduce the strain on the user's lower back.

[0022] Furthermore, by using four handles when lifting one assembled cardboard box, it can be carried by a team of two people, and even if the cardboard box is large or the object packed in it is heavy, it can be carried. [Explanation of symbols]
