Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended for use in home air conditioners, air conditioner cooling devices, hot air heaters, oil stoves, and other air conditioning-related products, televisions, stereos, refrigerators, washing machines, Among durable consumer materials including electric appliances such as dryers (laundry) and microwave ovens, industrial equipment such as various motors and pumps, sanitary ware products such as toilet bowls, wash water tanks, washbasins, etc. TECHNICAL FIELD The present invention relates to a pulp molding packaging material suitable for packaging of a deformed product that has been held.

[Conventional technology]

Air-conditioning related products, electrical products, industrial equipment products, and sanitary ware products are packaged at the factory shipment stage to prevent surface flaws and damage during the distribution process. For example, since a flush toilet and the like have a complicated shape and are bulky, generally, a plurality of corrugated cardboard pieces and the like are used to cover almost the entire product.

FIG. 6 shows a packaging state of the product A to be packaged by the conventional method. In this packaging form, a plurality of corrugated cardboards 50 are placed on the upper and lower surfaces of the product A to be packaged, and the periphery thereof is covered with a resin band.
51 united. Further, in order to reduce the impact in the distribution process, between the corrugated board 50 and the product A to be packaged,
In particular, it is common practice to replenish the corrugated cardboard cushioning pieces 52 mainly at the corners and the like.

[Problems to be solved by the invention]

However, since a plurality of corrugated boards 50 are set on the product A to be packaged, it takes time to perform setup before the binding process and to set the position of the corrugated boards 50. Further, in order to bind and fix a plurality of corrugated cardboards 50 around the product A to be packaged, the number of the resin bands 51 to be wound increases.

Therefore, there is a limit to shortening the packaging time for each product, and since multiple corrugated cardboard 50 sets rely on manual work by the operator, it is not possible to accurately grasp the working time and the throughput, and the management is difficult. It was also a hindrance.

Further, due to the expansion of product specifications, the shape and the number of the corrugated board 50 to be prepared are changed in a complicated manner, and as a result, full automatic packaging cannot be realized. Also,
Due to the complicated and diversified shape and number of the corrugated board 50, the efficiency in terms of handling at the work site has been impaired, which has been an obstacle to improving productivity.

In addition, after packaging, the packaged items are stacked on top of each other or stored or transported side by side, so that adjacent packaged items interfere with each other. For this reason, in the case of a heavy article such as sanitary ware, there is a possibility that the upper and lower surfaces of the product to which the load is applied and the upper and lower surfaces of the side surface may be damaged. To prevent this, for example, it is effective to apply an auxiliary cushioning material that covers the corners of products that are prone to chipping, but if this work is included, the efficiency of the packaging process will be considerably reduced and the automatic packaging line will It cannot be applied to. In the case of cardboard packaging, since the material itself has a low cushioning property, insufficient protection of the product remains, and often the product surface is damaged.

The problem to be solved in the present invention is to provide a pulp-molded packaging material which has a high cushioning property to prevent the product surface from being damaged during storage and transportation and at the same time can be applied to an automatic packaging line. It is in.

[Means for solving problems]

The present invention is a packaging material integrally formed by pulp molding in a trough shape with a main cover portion covering one surface of a product to be packaged and a side plate bent from an edge portion of the main cover portion. The part has a concavo-convex cross-sectional shape with a banding groove for hanging a band for bundling and a reinforcing groove dispersed in almost the entire region and having a bottom portion of the groove as a buffer convex surface for contacting the surface of the packaged product. , A rim shape projecting outward is provided on the entire circumference of the end edge portion of the side plate, and the side plate further includes a side reinforcing groove continuous with the reinforcing groove and a side band engaging groove continuous with the band engaging groove. Each is extended to the vicinity of the rim-shaped portion.

〔Example〕

The features of the present invention will be specifically described below with reference to embodiments.

The pulp molding packaging material 1a of the present invention, as shown in FIGS. 1 to 3 (a) and (b), includes a flush toilet bowl as a packaged product 11
Is formed so as to cover the upper part thereof.

The pulp molding packaging material 1a is a pulp mode molded product containing pulp as a main raw material, and is obtained by heat molding with a molding hot press after processing with a molding machine in a paper mill. This pulp molding packaging material 1a is a product to be packaged 11
Is formed in a trough shape composed of a main cover portion 2 that comes into contact with the upper surface of the side plate, and a side plate 3 that is integrally connected to the outer periphery of the main cover portion 2 in a semi-open manner.
Further, the pulp molding packaging material 1a is assumed to have a uniform wall thickness capable of elastically deforming the whole, so that the flexibility of the material and the elastic deformation can be used to protect the packaged product 11. .

The main cover portion 2 is provided with a band-engaging groove 4 that intersects so that the band 10 can be easily worn. The back surfaces of these recessed and crossed band hanging grooves 4 and reinforcing grooves 8 are
As shown in the figure, the cushioning convex surface 6 that contacts the packaged product 11 is formed.

Further, the side plate 3 is provided with a side reinforcing groove 9 independently or by connecting to the reinforcing groove 8 provided in the main cover portion 2. As shown in FIG. 1, the reinforcing groove 8 is provided in a region along the edge of the main cover portion 2, and all of them have a shape in which the surface of the main cover portion 2 that bends toward the side plate 3 is open. That is, the main cover portion 2 has a shape that is carved from the edge portion of the main cover portion 2 toward the center side thereof with a substantially uniform depth, and the edge portion of the main cover portion 2 has a recess like the band hanging groove 4.

When the reinforcing groove 8 and the band-hanging groove 4 are provided in a recessed manner in this way, when the pulp molding packaging materials 1a or 1b are stacked and stored, the recesses of the reinforcing groove 8 and the band-hanging groove 4 are formed. By utilizing the shape, it is possible to stack the upper and lower pulp molding packaging materials 1a or 1b in a state where they are positioned, and it is possible to carry them mechanically into an automatic packaging line.

As shown in FIG. 1, it is preferable that the side plate 3 is provided with display portions 7a and 7b for printing or attaching labels or the like.

Further, the side plate 3 is provided with a side band hooking groove 5 which is connected to the band hooking groove 4 of the main cover portion 2. The side band hanging groove 5 reinforces the side plate 3 together with the side reinforcing groove 9,
Improves overall shape retention. Then, the cushion convex surface 6 acts in the same manner as when it is expanded laterally, and buffers the impact to the packaged product 11 against the external force from the side and protects the packaged product 11.

The side band hooking groove 5 acts as a band hooking guide, and the band 10 is better hooked than in the case where only the band hooking groove 4 intersecting with the main cover portion 2 is recessed, and the band 10 is positioned and displaced. It has a preventive effect. The side band hooking groove 5 is formed from a point where the side plate 3 is bent as shown in the drawing toward the end side thereof, and is provided so as to define the recessed region while leaving the end part of the side plate 3. That is, the side band hooking groove 5 is formed so as to be continuous with the band hooking groove 4 of the main cover portion 2,
As shown in the figure, the end portion of the side plate 3 has a rim shape slightly protruding outward so that a recessed region is formed at the end portion of the side plate 3 so as to have a closed groove space.

With such a shape of the side band hooking groove 5, even if it is a general pulp-molded product which is easily deformed, when the band 10 is tightened when it is hooked, the end of the side plate 3 is not a groove. Since the meat is left as if it had been trimmed, the deformation is suppressed. That is, the edge portion of the side plate is formed in a rim shape protruding outward so as to suppress the deformation of the edge portion, and the end of the side band hooking groove 5 is near this rim portion. Therefore, even when the band 10 is hooked, Side plate 3
It will not be deformed unnecessarily.

On the other hand, since the side reinforcing groove 9 also extends to the vicinity of the rim at the edge of the side plate 3, the side reinforcing groove 9 can also be used for reinforcing the rim portion. Therefore, if the side reinforcing groove 9 is provided along the side band hooking groove 9, it is effective to suppress the deformation of the rim portion when the band 10 is tightened.

In this way, the easiness of deformation of the pulp-molded product can be used to perform packaging conforming to the outer contour of the product 11 to be packaged, and at the same time, the shape retention of the tightened portion of the band 10 to which the most external force is applied is maintained. , Can be shipped as a well-packaged product.

1 and 3 (a) and (b), 1b covers the lower part of the product 11 to be packaged, so that it is molded so as to fit the outer surface thereof and has the same characteristics as the pulp molding packaging material 1a. It is a pulp molding packaging material.

FIGS. 4, 5 (a) and 5 (b) show an example in which a triangular cornered low tank provided in a corner of a toilet is packaged as the product 11 to be packaged. In these figures, members similar to those shown in FIGS. 1 to 3 are designated by common reference numerals, and detailed description thereof is omitted.

Pulp molding packaging material 1a, 1b has a shape respectively adapted to the outer shape of the upper and lower parts of the product 11 to be packaged, as in the case of the above embodiment, the upper and lower parts of the product 11 to be packaged pulp molding packaging material. It can be wrapped with 1a and 1b, respectively.

Since the pulp molding packaging materials 1a and 1b are both flat container shapes, the action of placing the packaged product 11 on the lower molding packaging material 1b and the work of covering the upper pulp molding packaging material 1a on the packaging product 11 are easy. Is. In other words, compared to the case where a plurality of corrugated board and cushioning material are set around the packaged product 11 as in the conventional case, only two pulp molding packaging materials 1a and 1b need to be handled, so the work load is significantly smaller. Become. Further, the flat container-like shape of the pulp molding packaging materials 1a and 1b allows easy positioning with respect to the product 11 to be packaged, and the skill required for the conventional work of applying corrugated cardboard to the surroundings is unnecessary.

By the way, in the packaged state of the packaged product 11, the cushioning convex surface 6 constituted by the banding groove 4 and the like of the pulp molding packaging materials 1a and 1b intersects the surface including the upper and lower corners of the packaged product 11. Therefore, it is possible to provide a buffer against external force. That is, the panel-shaped packaging material cannot protect the product unless the cushioning material is replenished, but an effective cushioning ability is obtained. As a result, it is not necessary to replenish the cushioning material, and when the cushioning material deviates from a predetermined position, the inconveniently inconvenient aspect that the cushioning function does not work is solved. Therefore, in addition to the simplification of the packing work and the work on the automatic packing line, the packing form including the protection of the product can be obtained.

[Effect of device]

In the present invention, the strength of the main cover portion is secured by the banding groove and the reinforcing groove provided in the main cover portion, the deformation of the packaging material is prevented, and the bulk of the reinforcing groove and the flexibility of the pulp mold material are secured. By utilizing, it is possible to obtain a sufficient cushioning effect during storage and transportation of the upper and lower parts of the packaged product. In addition, by integrating the main cover portion and the side plate and ensuring the shape retention, mounting on the product to be packaged becomes extremely easy, and processing by automatic packaging becomes possible.

In addition, since the band hooking groove and the reinforcing groove are formed continuously from the main cover part to the side plate, the strength and shape retention of the packaging material are ensured, and the side band hooking groove and the side part are secured. The rim-shaped portion of the side edge of the reinforcing groove The side edge is reinforced by the step and the rim-shaped portion of the side edge, and together with the effective use of the elasticity of the pulp mold material, the surrounding products, etc. The impact due to contact with can be sufficiently absorbed and the product can be prevented from being damaged during transportation.

Further, the reinforced side plate edge prevents the breakage or damage of the packaging material during banding or during the distribution process even if the material is pulp that is relatively easily broken. Therefore, it is possible to maintain an appropriate packing form, suppress buffering with surrounding products and the like, and prevent scratches and defects of the packaged product due to breakage or damage of the packaging material.
