Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a packaging device for packaging objects such as air conditioners, and in particular, the present invention relates to a packaging device for packaging objects such as air conditioners. The present invention relates to a packaging device in which a reinforcing member can be easily and firmly attached and prevented from moving without using separate parts.

[Technical background of the invention and its problems] Generally, when transporting an air conditioner etc. from an assembly factory, the air conditioner is packed using a packaging device that assembles packaging materials such as cardboard into a rectangular shape. ing.

By the way, since there are cases where items are accidentally dropped during cargo handling and transportation, in order to prevent deformation of the packaging device and damage to the air conditioner, which is the packaged item, from this impact force, it is necessary to apply a particularly concentrated load. For example, reinforcing members made of metal are provided at the corners of the packaging device.

Here, a conventional packaging device will be explained based on FIGS. 1 and 2. As shown in the figure, this packaging device is constructed by assembling packaging members 1 such as cardboard boxes into a rectangular shape, and the inner bottom corners 2 A hollow pyramid-shaped reinforcing member 3 is provided in close contact with the reinforcing member 3, and
A flat lower cushion 5 is inserted from above the lower surface 4 of the reinforcing member 3 to restrict movement of the reinforcing member 3.

However, in the case of the conventional packaging device, the lower cushion 5, which is a separate component, is required to restrict the movement of the reinforcing member 3, which not only increases manufacturing costs but also causes a decrease in work efficiency.

[Purpose of the invention] The present invention has been devised to focus on the above-mentioned problems and to effectively solve them.

The purpose of the present invention is to easily and firmly mount and prevent movement of reinforcing members provided at the inner corners of a rectangular packaging device without using separate parts;
Moreover, it is an object of the present invention to provide a packaging device that can improve assembly work efficiency.

[Summary of the invention] The present invention involves assembling and forming packaging members such as cardboard into a box shape, in order to package items such as air conditioners, and forming a corner part consisting of a bottom and side parts of the packaging member. In the packaging device, a reinforcing member is provided at the lower end of the packaging member, and a bottom flap is provided at the lower end of the packaging member to form a bottom portion by being folded inward at a substantially right angle, and a locking flap is provided at the end of the bottom flap so as to be able to be folded back. The reinforcing member is sandwiched between the locking flap and the bottom flap, thereby achieving the above object.

[Embodiment of the invention] A preferred embodiment of the invention will be described below in detail with reference to the accompanying drawings.

First, FIG. 3 is a perspective view showing a corner of the packaging device according to the present invention, and FIG. 4 is a partially exploded view of the packaging device.

As shown in the figure, this packaging device is for packaging a substantially rectangular packaged object such as an air conditioner (not shown), and is entirely composed of a packaging member 1 such as cardboard, for example. By folding and assembling this, an outer box can be formed. Therefore, as shown in the exploded view of FIG. 4, the portion corresponding to the side portion 6 of the outer box is formed into a horizontally long rectangular shape, and a bending line 7 is formed in the vertical direction in the middle thereof. In the illustrated example, the side portion 6 is
Only the side is described, and the others are omitted because they are the same.

Further, two through holes 8 are formed in the side portion 6 so as to pass through the packaging member 1, and these form a handle portion 9. A glue allowance 10 is provided on one side of the side portion 6 so as to be bendable along the vertical direction.

Further, above this side part 6, that is, at the upper end of the packaging member 1, a rectangular top lid flap 12 is separated by a folding line 11 at a portion corresponding to the folding line 7 formed on the side part 6. Each is provided.

Similarly, a rectangular bottom flap 14 is formed below the side part 6, that is, at the lower end of the packaging member 1, via a bending line 13, and can be folded inward at almost right angles during assembly. ing. This bottom flap 14 is separated into left and right parts at a portion corresponding to the bending line 7 formed on the side part 6, and one side (the right side in the illustrated example) constitutes the bottom inner flap 14a, and the other side (in the illustrated example) constitutes the bottom inner flap 14a. the left side) constitutes the bottom outer flap 14b,
During assembly, these are bent so that the bottom outer flap 14b is located at the bottom as shown in FIG. It goes without saying that the bottom outer flap 14b and the bottom inner flap 14a may be provided in opposite directions. And these both bottom flaps 14
There is a bend line 1 along the longitudinal direction at the end of the
5, rectangular locking flaps 16, 16 are provided so as to be foldable. As shown in the figure, this locking flap 16 is a hollow triangular pyramid-shaped metal reinforcing member 3 that is brought into close contact with the corner 2 of the outer box during assembly.
It is for locking.

Next, the operation of the present invention will be described.

First, each side portion 6,
6 is bent at a substantially right angle and the ends are joined together with a glue allowance 10 to form an exterior box with an open top and bottom. Then, the bottom inner flap 14a provided at the lower end of the packaging member 1 is first bent inward at a substantially right angle, and then the bottom outer flap 14b is similarly bent inward at a substantially right angle. Overlap them vertically at corner 2.

Then, a hollow triangular pyramid-shaped reinforcing member 3 is installed in close contact with the corner 2 so that its apex is pressed, and the locking flap 16 provided at the end of the bottom inner flap 14a is directed toward the reinforcing member 3. hand
Fold it back 180 degrees and lock it from above the lower surface 4 of the reinforcing member 3. As a result, the reinforcing member 3 is attached to the locking flap 1.
6 is pressed against the corner 2 of the outer box, and this movement can be reliably regulated. The object to be packaged is then housed in the outer box assembled in this way.

In the illustrated example, only one corner is shown, but it goes without saying that the reinforcing member 3 can be similarly attached to other corners.

Further, in the illustrated example, the entire locking flap 16 is bent, but the invention is not limited to this. For example, a cutting line may be provided at a portion appropriately spaced from the top 17 of the flap, and only the end portion of the flap may be bent. may be folded back.

In this way, by folding back the locking flap 16, the bottom of the outer box is made up of three layers of cardboard, creating a lower cushion effect.

Furthermore, the lower cushion required in the conventional example for fixing the reinforcing member is no longer required.
Since no separate parts are used, it not only improves work efficiency but also reduces material costs.

Next, a buffer member used in a packaging device will be described as a technology related to the above embodiment.

This cushioning member is intended to prevent damage to the front plastic panel of an air conditioner or the like due to impact force if the item is dropped during cargo handling and transportation.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects can be achieved.

(1) Since the reinforcing member can be fixed simply by folding back a part of the packaging member, separate parts that were conventionally required can be eliminated, and work efficiency can be improved.

(2) By eliminating the need for separate parts, material costs can be significantly reduced.

(3) Since the structure is simple, it is easy to manufacture and can be provided at low cost.

(4) By folding back the locking flap, the bottom of the outer box is made up of three layers of cardboard, creating a lower cushion effect using just the cardboard.
