Description

Packing shock absorber for corrugated cardboard {packing shocking absorber for corrugated cardboard}

The present invention relates to an environmentally friendly packaging buffer for corrugated cardboard while safely and collectively transporting and storing a plate-shaped panel product, and more particularly, to a cardboard packaging buffer having a space in which the storage side of the panel does not touch the whole.

As a conventional packaging cushioning material for corrugated cardboard, for example, the one disclosed in Korean Registered Utility Model Publication (No. 20-210376) has been proposed.

1 is a perspective view folds one side of the conventional packaging cushioning for cardboard, Figure 2 is a perspective view showing a state completed by folding the other side in the state of Figure 1 even.

As shown in Fig. 1 and Fig. 2, the conventional packaging buffer 10 is composed of a pair of support plates (1) (1a), the base (2), the receiving opening (3) and the corrugated panel (4). The support plate (1) (1a) is composed of a corrugated cardboard of the buffer type that is integrally laminated by cutting the corrugated cardboard in order to effectively cushion or disperse external moisture or foreign matter and impact.

Each support plate (1) (1a) is located at the left / right end with a certain distance from each other, this separation distance is calculated by the distance corresponding to the corresponding distance in consideration of the size (length) of each extension surface (2a). On the surface of each position-fixed support plate (1) (1a), the plate-shaped corrugated paper is integrated by adhesively fixing in the longitudinal direction with the base (2), the front and rear of each support plate (1) (1a) In the upper direction is formed to extend the folding surface (2a), the intermediate position of the support plate (1) (1a) facing each other is also spaced apart so that the extension surface (2a) in each direction can be formed Extension surfaces 2a are formed in a collapsible size.

In addition, the left and right sides of the support plate (1) (1a) to extend the side surface of the base (2) to a size corresponding to the length thereof so that the wing surface (2b) can be formed to be folded upward also the base (2) ) Will be fixed by cutting.

Thereafter, the receiving opening 3 is tightly fixed to the straight upper base 2 of the supporting plate 1, 1a. The receiving opening 3 has a plurality of cut pieces of corrugated cardboard, the upper and rear ends of which are respectively opened. It is bent in the U-shaped longitudinal direction so that the slots 3a in the longitudinal direction are formed and then connected to each other so as to be located on the inner side of the above-described wing surface 2b. The liquid crystal display panel and the like are fitted to be accommodated. Each of the extension surface 2a and the wing surface 2b is provided to protect the product thus stored by being folded at both front and rear ends and left and right sides. For this purpose, the extension surface 2a and the wing surface 2b are provided. The buffered corrugated panel 4, which is also cut and integrated with a plurality of corrugated cardboards, is fixed on the surface of the surface, thereby enabling close protection in each direction. As shown in FIG. 1 and FIG. By folding the device, it is possible to effectively fold the product stored in the base (2) storage port (3) of the left / right ends to be stored in the packing box or sealed.

However, the conventional storage port 3 is formed by bending a plurality of corrugated cardboard cut in the longitudinal direction of the U-shape to form a slot (3a) in the longitudinal direction and then connected to each other to the inner surface of the wing surface (2b) described above. Since it is formed to be bonded to position, there is a need to adhere the support plate (1) (1a) to the straight upper base (2) to further mitigate the impact.

In addition, since the extended surface (cover) 2a is placed on the upper end of the storage opening 3, the corrugated cardboard forming the plurality of slots 3 may swing back and forth. Thus, the panels can also move together to hinder the packaging stability of the product.

In addition, when the panel is housed, since the entire side of the panel touches the side of the slot 3a, the external shock is transmitted to the entire side of the panel as it is, which may adversely affect the precision electronics.

In addition, since the opening 3 is adhered to and fixed on the wing surface 2b, there is no deformation (fluidity). The cushioning function may be impaired.

The present invention has been made to solve the above-described problem, and an object thereof is to provide a packaging cushioning material for corrugated cardboard which is convenient for storing by allowing a storage error even though the storage size is slightly different while significantly canceling the external impact.

In order to solve the above problems, the packaging cushioning material for cardboard according to claim 1 of the present invention,

Claims [1] A cardboard cushioning material for corrugated cardboard disposed on left and right sides of a packaging box for receiving a plate-shaped product, the lower plate; A side plate bent vertically extending from one side of the lower plate; It includes a plurality of storage compartment plate is provided on the inner side of the side plate to form a plurality of storage compartment,

The upper side portion and the lower side portion of the side plate are thicker than the central side portion of the side plate.

According to this configuration, even if the storage size is slightly different while significantly canceling the external impact, the difference in thickness allows the storage error, and the storage is convenient.

Corrugated cardboard packaging buffer according to claim 2 of the present invention,

The lower plate is a lower lower plate extending in a horizontal direction from the lower end of the side plate inward, an upper lower plate bent upward from the free end of the lower lower plate, and the upper lower plate to support the lower side of the plurality of storage compartment plate An upper lower plate bent in a horizontal direction from the end to the outer side, and a honeycomb lower plate interposed between the upper upper plate and the lower lower plate; An upper side plate bent upward from a free end of the upper lower plate, a horizontal side plate bent horizontally from the free end of the upper side plate toward the side plate, and between the horizontal side plate and the honeycomb steel plate A honeycomb side reinforcing plate interposed therebetween is further installed; An upper honeycomb side reinforcing plate and an upper side corrugated board are further formed on the side plate of the upper part, and one end of the storage compartment plate is preferably provided with a protruding end to be fitted between the upper part and the lower part of the side plate.

As is apparent from the above description, the embodiment of the present invention has the following effects.

The upper side and the lower side of the side plate are formed thicker than the center side of the side plate, so that even if the panel is longer than the storage size (i.e. both lengths), even if the entire side of the panel is not touched and is not subjected to an external impact as a whole, The space that is pushed out under pressure allows for storage without damaging the packing material.

In addition, since the upper and lower projecting end portions of the storage compartment plate fit the bottom surface of the side plate upper portion and the top surface of the side plate lower portion, they serve to support the upper side of the side plate.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a front perspective view showing a packaging cushioning material for a corrugated cardboard according to a preferred embodiment of the present invention, Figure 2 is a front perspective view showing a plurality of storage compartment of Figure 1, Figure 3 is a side view covering the top plate of Figure 1 4 is a perspective view showing a state of use before being inserted into a packaging box, and FIG. 5 is a cross-sectional view taken along line 5-5 of FIG. 4.

As shown in Figures 1 to 5, the packaging buffer 100 according to an embodiment of the present invention is a lower plate 110, and the side plate 120 which is bent vertically extending at one end of the lower plate 110, The upper plate 130 is bent at the upper end of the side plate 120, and the plurality of storage compartments 150 are provided on the inner surface of the side plate 120 to form a plurality of storage spaces (150a).

A plurality of fitting grooves 155b are formed on a lower surface of the upper plate 130, and fitting protrusions 155a are formed at upper ends of the storage compartment plates 150, respectively. The term fitting groove 155b in the detailed description and claims of this embodiment includes not only the groove but the concept of a through hole.

When the upper plate 130 covers the upper end of the storage compartment plate 150, since the fitting groove 155b is fitted into the fitting protrusion 155a, the respective storage compartment plates 150 are prevented from hitting each other back and forth to prevent them from hitting each other. The protection function of panel products can be further increased.

In addition, the upper plate 130 is an upper upper plate 131 which is bent and extended from the upper end of the side plate 120, a lower upper plate 133 that extends bent downward from the free end of the upper upper plate 131, and the lower upper plate 133 It is composed of a corrugated cardboard of the lower upper plate 135 which is bent and extended from the free end of the upper upper plate 131 to face.

In addition, it is preferable that the honeycomb upper reinforcing plate 137 interposed between the upper upper plate 131 and the lower upper plate 135 is further installed on the upper plate 130.

Honeycomb top reinforcing plate 137 is thicker than corrugated cardboard, but has a light and heavy load-bearing property is very useful when laminating up and down the packaging box (PB) packing a large product.

Meanwhile, as shown in FIG. 3, the thickness T of the upper portion 120U and the lower portion 120L of the side plate 120 is greater than the central side thickness T of the side plate 120 (that is, the thickness of the side plate). It is preferable to form thickly.

That is, the upper side portion 120U of the side plate 120 is a portion in which the honeycomb side reinforcement plate 125U and the side corrugated cardboard plate 121U are further stacked.

The lower side 120L of the side plate 120 has an upper side plate 121L bent upward from the free end of the upper lower plate 115 and a horizontal side bent toward the side plate 120 from the free end of the upper side plate 121L. The horizontal side plate 127L and the honeycomb side reinforcing plate 125L interposed between the horizontal side plate 127L and the honeycomb reinforcing plate 117 are comprised.

As shown in FIGS. 4 and 5, the horizontal side plate 127L is preferably provided with a fitting protrusion 159a fitted to the fitting slit 159b formed in the side plate 120.

Of course, it is good to implement so that the storage compartment plate 150 does not fall by applying the adhesive around the fitting slot fitted with the fitting protrusion.

Due to this difference in thickness d, when the side surface of the panel is accommodated in the storage space 150a, only the corrugated board 121U of the upper part 120U and the corrugated board 121L of the lower part 120L are contacted. External shocks are not transmitted to the entire panel.

In addition, even if the left and right length of the panel is slightly longer than the left and right packaging buffer 100, the upper portion 120U and the lower portion 120L is allowed to be pushed toward the center side by the pressure of the panel when inserted from the top to the bottom, so that the panel does not enter. It can be prevented from being damaged or torn when inserted forcibly.

2, the fitting protrusion 155a is formed at the upper end of the storage compartment 150, and the fitting protrusion 157a is fitted at the fitting slot 157b formed at the upper lower plate 115 at the lower end thereof. Constrained by the upper lower plate 115 and the lower upper plate 135 to be described later it is good to prevent the shaking back and forth.

In addition, the fitting protrusion 153a fitted to the fitting slot 153b formed on the side plate 120 protrudes in a horizontal direction at one end of the storage compartment plate 150, and is almost entirely vertically in one end side of the storage compartment plate 150. Restraint can be more firmly prevented from shaking back and forth.

In addition, it is preferable that the fitting protrusion 154a fitted to the fitting slot 154b formed on the top plate side plate 121L is formed in the storage compartment plate 150.

In addition, the upper and lower projecting end 151 is formed in the storage compartment plate 150. The upper and lower projecting end portions 151 are fitted between the bottom surface 127U of the upper portion 120U and the upper surface 127L of the lower portion 120L when the fitting protrusion 153a is fitted into the fitting slot 153b. It serves as a pedestal for the upper side 120U.

In addition, the storage compartment plate 150 is a corrugated cardboard having a corrugated core (C) of the corrugation, it is preferable that the corrugated corrugated core (C) of the corrugation is arranged on the upper and lower surfaces rather than the left and right.

This vertically arranged corrugated corrugated core (C) is like a role of a pillar, the resistance to the pressing force from the top is much greater than the left and right.

It is preferable that the honeycomb left and right reinforcing plates 160 are attached to both front and rear sides of the storage compartment plate 150.

On the other hand, the upper top plate 131 is preferably implemented by the first upper side plate 131a and the second upper side plate 131b.

The first upper upper plate 131a is hung over the upper end surface of the side plate upper side 120U, and the second upper upper plate 131b functions to cover the upper end of the storage compartment plate 150.

That is, the upper end surface of the side plate upper part 120U is at a position h higher than the fitting protrusion 155a of the storage compartment plate 150, so that when the upper plate 130 is covered, the upper end surface of the side plate upper part 120U is It acts as a stopper to prevent damage by being inserted into the fitting protrusion 155a by force.

In addition, since the second upper plate 131b is foldable with respect to the first upper plate 131a, when the upper plate 130 is not covered, the second upper plate 131b may be folded backward as shown in FIG. 1, thereby reducing the storage height.

As described above, although described with reference to a preferred embodiment of the present invention, the present invention can be variously modified or modified without departing from the spirit and scope of the present invention described in the claims Those skilled in the art will appreciate.

The present invention can be applied to any cardboard packaging buffer having a storage space in the form of a storage compartment.
