JP4662553B2 - Wrapping member and assembly type package using the same - Google Patents

Description

  The present invention relates to a packaging member and an assembly-type packaging body using the packaging member, and can be used for packaging, for example, a water heater or a gas stove.

As a technique for packaging an object to be packaged such as a television receiver, the one shown in FIG. 6 (Patent Document 1) is known.
In this case, cushioning materials (11) and (11) having an L-shaped cross section made of polystyrene foam or the like are externally fitted to the upper and lower left and right corners of an object to be packaged (2) such as a television, and in this state, an accessory pad ( The outer case (4) is filled together with the accessory (22) stored in 21). In this case, even if an impact during transportation or the like acts on the package, the shock is absorbed by the cushioning material (11) (11) and is not easily transmitted to the internal package (2). The object (2) is protected and its damage can be prevented.
JP-A-7-187248

However, in the case of the above conventional one, the load receiving surface (contact surface with the bottom surface of the packaged object (2)) of the cushioning material (11) (11) that contacts the bottom surface of the packaged object (2) cannot be increased. However, there is a problem that the packaged object (2) cannot be sufficiently protected.
The above problem will be further described in detail.
The size of the load receiving surface of the cushioning material (11) (11) (the contact surface with the bottom surface of the packaged object (2)) should be wider and excessively compressed when the packaged object (2) is heavy than when it is light. It is necessary to prevent deformation.

However, for example, in order to wrap various pipe connection ports such as gas, water, hot water, etc., as well as a water heater with a water drain plug or power cord protruding from the bottom, a buffer is provided outside the pipe connection port. The materials (11) and (11) are brought into contact with each other, so that it is necessary to avoid interference between the pipe connection port and the buffer materials (11) and (11). Therefore, if the area of the piping connection port is large compared to the bottom area of the water heater, the load receiving surface (contact surface with the water heater bottom surface) of the cushioning material (11) (11) should be sufficient. I can't make it bigger. And if the size of the load receiving surface is insufficient, the stress caused by the water heater is concentrated on the buffer material (11), and if the package is accidentally dropped, the buffer material (11) (11) is large. Compressed. As a result, there is a concern that the pipe connection port or the like protruding from the bottom surface of the water heater as the article to be packaged (2) may collide with the floor surface and be damaged. Therefore, in the case of packaging the packaged object (2) having a structure in which the load receiving surface (contact surface with the bottom surface of the packaged object (2)) cannot be increased, (2) cannot be adequately protected.
Note that when the hardness of the cushioning material (11) (11) is increased in order to solve the above problem, the cushioning property is lowered. Similarly, it cannot be adequately protected.

The present invention has been made in view of such points.
When the contact area with the bottom surface of the article to be packaged (2) cannot be increased in "Packaging material with cushioning material (11) that receives the load from the article to be packaged (2) from below" However, it is an object to provide a packaging member that can exhibit sufficient buffering properties.

[Invention of Claim 1]
The solution means of the invention according to claim 1 for solving the above-mentioned problem is as follows:
`` A frame-shaped plate (30) that is in surface contact with the outer peripheral area of the bottom surface of the article to be packaged (2) and has a larger outer peripheral shape than the bottom surface,
The buffer material (11) is fixed to the lower surface of the frame-like plate (30) so that the frame-like plate (30) can be supported in a substantially horizontal state from below ”.
Here, the frame-like plate (30) is a concept that includes a continuous frame over the entire circumference or a part of the frame-shaped plate (30) that is notched and discontinuous.
According to this solution, the load from the article to be packaged (2) receives the cushioning material (30) that supports the frame-shaped plate (30) via the frame-shaped plate (30) in surface contact with the outer peripheral area of the bottom surface. Received in 11).
In this case, since the frame-shaped plate (30) has a larger outer peripheral shape than the bottom surface of the packaged object (2), the load from the packaged object (2) is dispersed by the frame-shaped plate (30). The damping force acts on each part of the cushioning material (11). Therefore, the load per unit area acting on the cushioning material (11) is smaller than that of the conventional one described above in which the outer periphery of the bottom surface of the package (2) is directly supported by the cushioning material (11).
Therefore, as described above, even if it is not possible to increase the contact area with the bottom surface of the article to be packaged (2), such as a water heater in which various pipe connection ports protrude from the bottom surface, the cushioning material ( 11) Sufficient buffering property can be secured.

[Invention of Claim 2]
In the invention according to claim 1,
`` In the upper surface of the frame-shaped plate (30), an elastic block for positioning that sandwiches the packaged object (2) in the horizontal direction '' is disposed. 2) is sandwiched from the horizontal direction and stabilized.

[Invention of Claim 3]
In the invention according to claim 1 or claim 2,
In "the frame-shaped plate (30) is provided with a pad member that contacts the bottom surface of the packaged object (2)", the frame-shaped plate (30) is hard because the pad member is provided. Even if it is made of a material, the packaged object (2) is hardly damaged. Further, even if there is a slight level difference on the bottom surface of the article to be packaged (2), this is absorbed by the pad member. As a result, it is possible to prevent inconvenience that the article to be packaged (2) is tilted on the packaging member to become unstable, or that an unbalanced load from the article to be packaged (2) acts on the frame plate (30).

[Invention of Claim 4]
The invention which concerns on Claim 4 is related with the assembly-type package body using the packaging member of the said Claims 1-3.
The solution of the invention according to claim 4 is:

[Packaging material (3) (3)]
The pair of upper and lower packaging members (3) and (3) have the same structure in the present embodiment, and are attached to the upper and lower portions of the water heater (20) by turning upside down.
As shown in FIG. 2, the packaging member (3) includes a rectangular frame plate (30) formed of a highly rigid material such as a hard synthetic resin plate or plywood, The inner peripheral shape is set slightly smaller than the outer periphery of the bottom surface of the water heater (20), while the outer peripheral shape of the frame plate (30) is set larger than the outer periphery of the bottom surface of the water heater (20).

  Notches (33) and (33) extend at both ends of the long side (34) of the frame plate (30), and the notches (33) and (33) have a main body case (200) of the water heater (20). ) And a front lid (201) (see FIG. 1), an outer peripheral flange (202) that projects is inserted. Also, the gas and hot water / water pipe connection ports (23) (23) protruding from the bottom surface of the water heater (20) enter the central hole (32) of the frame plate (30). Yes.

  As shown in FIGS. 1 and 2, a front pad (35) is in contact with the lower surface of the front lid (201) of the water heater (20) on the central upper surface of the long side portion (34) on the front side of the frame plate (30). ), The front pad (35) is formed of an elastic material made of polyethylene foam, and protrusions (350) (350) are provided at a predetermined pitch on the outer side thereof. The pad (35) may be made of a material such as expanded polypropylene, expanded urethane, or expanded polystyrene. The same applies to the materials of the side pad (37), the side block (38), and the rear block (39) described later.

The protrusions (350) and (350) are in contact with the inner surface of the front plate (400) constituting the lower case (40), and thereby absorb the forward impact on the water heater (20).
L-shaped side pads (37) and (37) extending to both end regions of the rear long side portion (36) are bonded to the upper surfaces of the pair of short side portions (31) and (31) of the frame-shaped plate (30). Thus, the range from the both sides of the bottom surface of the water heater (20) to the rear part is in contact with the inner peripheral regions (370) and (370) of the side pads (37) and (37).
The side pad (37) is formed of foamed polyethylene in the present embodiment.

  Side blocks (38) and (38) and a rear block (39) for positioning by sandwiching the water heater (20) in the horizontal direction are bonded to the outer periphery of the upper surface of each side pad (37). The side block (38) and the rear block (39) are formed of an elastic material made of polyethylene foam, and the protrusions (380) (380) provided on the outer side of the side block (38) and the rear The protrusion (390) on the rear side of the block (39) protrudes outward from the frame plate (30) in plan view. The protrusion (380) of the side block (38) contacts the inner surface of the side cover (41) loaded along the lateral plate (401) of the lower case (40), and the protrusion of the rear block (39). The part (390) abuts against the inner surface of the rear plate (402) of the lower case (40), thereby absorbing the horizontal impact on the water heater (20).

  The long side portions (34) and (36) and the short side portions (31) and (31) of the frame-shaped plate (30) have cushioning materials (11) and (11) made of a cushioning material such as foamed polystyrene and foamed polyethylene. Is attached, and the frame-like plate (30) can be supported substantially horizontally from below by the cushioning materials (11) and (11). Further, as is apparent from the upper packaging member (3) shown in FIG. 1, each cushioning material (11) has a shape in which convex portions (110) (110) protrude from the surface of a rectangular block at a predetermined interval. have.

[Exterior case]
The outer case (4) includes an upper open rectangular box-shaped lower case (40) that fits on a lower part of the water heater (20) (a packaging member (3) is stacked as described later), and a water heater. A rectangular box-shaped upper case (42) with a lower opening that fits over the upper part of (20) (the packaging member (3) is stacked as will be described later), and the side that protects the side surface of the water heater (20) The lower case (40), the upper case (42), and the side cover (41) are made of plastic cardboard. The reason for using the plastic cardboard is to return the unpacked outer case (4) together with the packaging member (3) to the shipping factory so that it can be reused (returnable).

  As shown in FIG. 3, the side cover (41) includes a bottom plate portion (410) that is superimposed on the bottom plate (403) of the lower case (40) and side plate portions (411) and (411) that are continuous at both ends thereof. A flat ring-shaped handle (43) is fitted in the middle of each side plate portion (411) in the longitudinal direction. Further, as shown in FIG. 1, the side plate (411) of the side cover (41) is compressed and flattened in the thickness direction below and above the handle (43) and the side plate (411). The formed linear folds (412) (412) are provided.

[Packaging work]
Next, the packaging operation of the water heater (20) will be described.
As shown in FIG. 1, the side cover (41) is folded in a U-shape, and the bottom plate (410) is placed at the bottom of the side cover (41) so that the bottom plate (410) overlaps the bottom plate (403) of the lower case (40). Into the lower case (40).
Next, the lower packaging member (3) is dropped into the lower case (40), and the water heater (20) is placed thereon. Then, the outer peripheral flange (202) formed in the fitting part of the main body case (200) of the water heater (20) and the front lid (201) is the inner ends of the long side part (34) of the frame-like plate (30). The lower surface of the front lid (201) is supported in surface contact with the front pad (35) of the packaging member (3). Further, the region extending from both sides to the rear of the bottom surface of the main body case (200) is supported in surface contact with the corresponding side pads (37) and (37). Thereby, since the water heater (20) is supported by the side pad (37) or the like, the hard frame plate (30) does not directly contact the packaged object (2). Therefore, the surface of the water heater (20) is hardly damaged. Further, even if there is a step on the bottom surface of the water heater (2), this is absorbed by the support portions of the front pad (35) and the side pad (37). Accordingly, it is possible to prevent the inconvenience that the water heater (20) is tilted and becomes unstable on the packaging member (3), and further that the unbalanced load acts on the frame plate (30) from the article to be packaged (2).

Also, the water heater (20) is fitted inside the side block (38) and the rear block (39) bonded to the upper surface of the side pads (37) (37). Positioned relative to the member (3).
Further, in the same manner as described above, the upper packaging member (3) (in a posture reversed with respect to the lower packaging member (3)) is placed on top of the water heater (20).

  Next, the side plate portion (411) of the side cover (41) is bent inward at the fold (412) portion above the handle (43), thereby, as shown in FIG. 3, the upper portion of the side plate portion (411) The regions (413) and (413) are placed along the upper surface of the upper packaging member (3). After that, when the upper case (42) is externally fitted on the outside of the upper part of the upper packaging member (3) and the side cover (41) and the entire upper and lower peripheries thereof are fastened by the packing band (51) (51), the water heater The packaging of (20) is completed (state shown in FIG. 3).

  In the packaging completion state shown in FIG. 3, the frame plate (30) constituting the packaging member (3) has a larger outer peripheral shape than the bottom surface of the packaged object (2). Load is distributed over a wide range of the entire frame-like plate (30), and this dispersed small force acts on each part of the cushioning material (11). Therefore, the load per unit area acting on the cushioning material (11) is reduced as compared with the conventional one described above in which the outer periphery of the bottom surface of the packaged article (2) is directly supported by the cushioning material (11).

  Therefore, a large contact area is secured to the bottom surface of the packaged object (2), such as a water heater (20) in which a large number of pipe connection ports (23), (23), etc. such as gas and water protrude from the bottom surface. Even if it is not possible to do so, sufficient cushioning properties by the cushioning material (11) can be obtained.

  Moreover, in the packaging completion state shown in FIG. 3, as described above, it projects sideways from the side block (38) provided on the surface of the frame plate (30) constituting the lower packaging member (3). The protrusion (380) abuts the inner surface of the side plate (411) of the side cover (41), and the protrusion (390) of the rear block (39) corresponds to the rear plate (402) of the lower case (40). The protrusion (350) of the front pad (35) provided on the long side (34) of the frame-shaped plate (30) is in contact with the inner surface, and contacts the front plate (400) of the lower case (40). Touch. Similarly, the protruding portion (380) of the side block (38) provided on the upper packaging member (3) also abuts on the inner peripheral surface of the side cover (41) and the like. Thereby, the impact in the horizontal direction acting on the water heater (20) is absorbed.

Next, an operation for returning the unpacked packaging member (3) and the outer case (4) to the shipping factory will be described.
When the packaging band (51) (51) is removed in the packaging completion state of FIG. 3 and the upper case (42) and the upper packaging member (3) are removed, the water heater (20) can be removed.

  Therefore, after removing the water heater (20), as shown in FIG. 4, the upper packaging member (3) is superimposed on the lower packaging member (3) housed in the lower case (40), The side cover (41) is folded at the folds (412) (412) so as to surround the outer periphery. Thereafter, when the upper case (42) is externally fitted to the lower case (40), as shown in FIG. 4, the entire packaging member according to the present embodiment is packed in a box shape, and this state Then, fasten the packing band (51) and return it to the shipping factory.

  The packaging member according to the present embodiment can be applied to packaging of a hot water heater (20) that is taller than that shown in FIG. When packaging a tall water heater (20), the upper area of the tip from the crease (412) formed above the handle (43) disposed on the side plate (411) of the side cover (41) (413) is erected, and in this state, packaging is performed in the same manner as described above. Then, since the upper area (413) at the tip of the side cover (41) that appears in FIG. 3 rises, the tall water heater (20) is packaged by the vertical dimension of the raised upper area (413). be able to. Even in this case, the distance from the bottom plate (403) of the lower case (40) to the handle (43) is the same as that when the short hot water heater (20) shown in FIG. 3 is packaged. In other words, the height from the floor surface to the handle (43) is not affected by the height of the water heater (20) as the packaged object (2), and can always be set at a position suitable for work and easy to hold.
