Description

  The present invention relates to a packing body, and more particularly to a returnable type packing body for packing a drop-in stove for a system kitchen, a range, a dishwasher, and the like.

  A conventional package is a so-called disposable one-way type, which is made of a packaging material such as cardboard or polystyrene foam capable of buffering and supporting a packaged object and is discarded after use. From the viewpoint of protecting the natural environment, it is shifting to a recyclable returnable type that is used repeatedly.

  As a returnable type package, a highly durable resin material is used so that it is not easily damaged even when external force is applied during cargo handling work or transportation, and can withstand repeated use for a long period of time. A plurality of resins having different properties can be combined and used in accordance with the material and shape of the object to be packed.

  For example, when packing the glass top plate (21) covered on the upper surface of the outer peripheral flange portion (20) of the upper open portion of the stove body (2) among the packing bodies used when packing the drop-in stove As shown in FIG. 5, the package used for this is a protective plate (10) interposed between the glass top plate (21) and the outer peripheral flange portion (20) of the stove body (2), and a protective plate ( 10) and a cushion member (11) placed on the left and right peripheral edges of the upper surface.

The protective plate (10) is composed of a highly durable polypropylene plate, and the cushion member (11) is composed of a highly cushioning polyethylene sponge. Is provided.
Thus, a storage space surrounded by the cushion member (11) and deeper than the thickness of the glass top plate (21) is formed on the upper surface of the protective plate (10), and the glass top plate (21) is placed in the storage space. By fitting and storing, the glass top plate (21) made of glass is stored in such a manner that it is protected from all directions.

However, in the above-described conventional package, the polypropylene protective plate (10) is integrally bonded with a different type of cushion member (11) made of polyethylene by adhesion or welding. When different types of resin materials are once bonded together by adhesion or welding, there is a problem that they are difficult to separate.
Therefore, when disposing of the combined body of the protective plate (10) and the cushion member (11), it takes time to separate the waste, and even if only the cushion member (11) is damaged, it cannot be partially replaced. Therefore, there is a problem that the entire package is replaced, resulting in high costs.

  The present invention has been made in view of such a point, and “the first packing material and the first packing material are made of different materials and have a cushioning property that absorbs an impact acting on an object to be packed. An object of the present invention is to make it possible to detachably combine the first packing material and the second packing material in the “packaging body formed by combining the packing material”.

(1) The packaging body of the invention according to claim 1 is: "The first packaging material and the second packaging material can be coupled with a detachable fastening member ;
Stepped first and second through holes each having a small diameter portion and a large diameter portion are provided at a plurality of locations facing each other of the first and second packing materials,
The fastening member has a diameter larger than that of the small-diameter portion, a sleeve having a head portion that can be inserted into the large-diameter portion, a shaft portion that can be inserted into the small-diameter portion, and a removable portion in the sleeve from the head side. A rivet pin that is press-fitted into the sleeve and expands the shaft portion of the sleeve,
When the sleeve is inserted from the large diameter portion of one of the first and second through holes, the shaft portion passes through the other small diameter portion of the first or second through hole and continues to it. When the rivet pin reaches the large-diameter portion and the rivet pin is press-fitted in this state, the shaft portion is configured to have a larger diameter than either one of the other small-diameter portions ”.
From the above configuration, the first packing material and the second packing material are overlapped so that the small diameter portions of the first and second through holes formed in both are in direct communication with each other. In this state, when the sleeve as the fastening member is inserted from the second through hole, for example, the head of the sleeve is locked to the stepped portion from the large diameter portion to the small diameter portion of the second through hole. The above insertion is prevented, and the shaft portion passes through the small-diameter portion of the first through hole and reaches the large-diameter portion continuous with the small-diameter portion. In this state, a rivet pin is press-fitted from the head of the sleeve. As a result, the shaft portion has a larger diameter than the small diameter portion in the large diameter portion, and is locked to the stepped portion from the small diameter portion to the large diameter portion of the first through hole in a retaining state. Note that the depth of the large diameter portion of the second through hole is set deeper than the thickness of the head portion of the sleeve. Since the rivet pin is detachable from the sleeve, the sleeve can be extracted from the first and second through holes by extracting the rivet pin from the sleeve and reducing the diameter of the shaft portion.
Thus, the 1st packing material and the 2nd packing material are couple | bonded by the fastening member instead of adhesion | attachment and welding. Since the fastening member is detachable from the first and second packing materials, when the entire packing body is disposed of or when the cushioning property of the second packing material is deteriorated and replacement is required, etc. When the fastening member is removed from the first and second packing materials, the first and second packing materials can be separated from each other.

(2) The packaging body of the invention according to claim 2 is the packaging body according to claim 1, wherein “the fastening member is connectable in a state of being embedded in the first and second packaging materials”. Then, when the first and second packing materials are combined with the fastening member, the fastening member is embedded in the first and second packaging materials as a whole, and a part of the fastening member protrudes outward. There is no.

( 3 ) The packaging body of the invention according to claim 3 is the packaging body according to claim 1 or 2 , wherein “the first packaging material is disposed below the glass top plate and is substantially the same as the glass top plate. In the case of a plate-shaped body made of hard resin having the same size and shape, the second packing material is a cushion member made of a soft resin disposed along the periphery of the upper surface of the plate-shaped body. The plate is supported by a plate-like body made of hard resin as the first packing material so as not to be inadvertently bent, and the impact on the glass top plate from above is made of soft resin as the second packing material. Absorbed by the cushion member. Moreover, after use, it is collected and reused.

As described above, according to the first aspect of the present invention , the first and second packing materials can be fixed simply by press-fitting the rivet pins into the sleeve as the fastening member, and the rivet can be easily removed from the sleeve. Therefore, it becomes easier to combine and separate the first and second packing materials. In addition, a well-known push return rivet can be employ | adopted as a fastening member.
In this way, by removing the fastening member, the first and second packing materials made of different materials can be easily separated, so that it does not take time for the separation work at the time of disposal.
Further, since the second packing material is made of a material having a cushioning property capable of absorbing the impact applied to the packed object, it may be plastically deformed, worn down or damaged by long-term use.

Even in such a case, the first and second packing materials can be separated and only the second packing material can be exchanged.
Therefore, the package can be repaired easily, and the waste of discarding the entire package can be suppressed and maintenance can be performed at low cost.

  Moreover, according to the invention which concerns on Claim 2, since a fastening member does not protrude outside in the state which combined the 1st and 2nd packing material, the coupling | bonding of these 1st and 2nd packing materials When packing an object to be packed with a packing body consisting of a body, the fastening member does not interfere with the packing, and an object or hand is inadvertently part of the protruding fastening member during cargo handling work or transportation There are no inconveniences like getting caught.

Moreover, according to the invention which concerns on Claim 3 , it can be used between a stove main body and a glass top plate as a package at the time of packing the drop-in stove which coat | covers the upper open part of a stove main body with a glass top plate. The glass top plate can be reliably protected by the first packing material made of a hard resin plate-like body and the second packing material made of a soft and highly cushioning cushion member.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  As described above, the glass top plate (21) was stored in a close fitting state in the peripheral wall pad (15) of the top plate storage pad (1) stored in a close fitting state in the storage box (12). In this state, it is housed in such a manner that it is placed on the protective plate (10) via the cushion member (11).

Therefore, the glass top plate (21) does not shift from front to back and left and right in the storage box (12), and the impact from above is absorbed by the cushion member (11). The glass top plate (21) can be reliably protected from external impacts applied during transportation.
The protective plate (10) corresponds to the first packing material in the claims, the cushion member (11) corresponds to the second packing material, and both are formed by the push turn rivet (4) as a fastening member. Fixed.

Next, a structure for joining the protective plate (10) and the cushion member (11) will be described.
As shown in FIG. 2, first and second through holes (30) and (33) are formed at a plurality of locations where the protection plate (10) and the cushion member (11) face each other.

  As described above, the protective plate (10) has a plastic three-layer structure, and the first through hole (30) is formed so as to penetrate all three layers, as shown in FIG. In addition, the small-diameter hole (30a) formed in the uppermost first protective plate (10a) is a large-diameter hole (through the other two second protective plates (10b) located in the lower layer (30a). It has a smaller diameter than 30b).

  Further, an auxiliary sheet (3) made of the same material as the cushion member (11) is bonded to the lower surface of the cushion member (11), and the auxiliary sheet (3) is formed on the cushion member (11). A small diameter hole (33a) formed smaller in diameter than the large diameter part (33b) is opened concentrically with the large diameter part (33b).

That is, the second through hole (33) is configured by a large diameter portion (33b) formed in the cushion member (11) and a small diameter portion (33a) formed in the auxiliary seat (3). The diameter of 33a) is the same as the small diameter hole (30a) of the protective plate (10).
As a result, both the second through hole (33) formed in the cushion member (11) and the first through hole (30) formed in the protection plate (10) have a small diameter portion (the small diameter hole (33a) and the small diameter). Hole (30a)) and a large-diameter portion (corresponding to the large-diameter hole (33b) and large-diameter hole (30b)). 10) is overlapped so that the small diameter portions are directly opposed to and communicate with each other.

  The push turn rivet (4) as a fastening member is made of a hard resin such as polypropylene, and as shown in FIGS. 3 and 4, the small diameter hole (33a) of the auxiliary sheet (3) and the small diameter hole of the protective plate (10). A head having a diameter substantially equal to the diameter of the large-diameter hole (33b) of the second through-hole (33) provided in the cushion member (11) at the upper end of the shaft portion (41) that can be closely inserted into the (30a) A sleeve (40) configured to include a portion (42), and an upper end of a screw shaft portion (44) screwed into a screw hole (43) penetrating the sleeve (40) in the axial direction. 40) and a rivet pin (46) provided with a flat head (45) of a size that can be fitted into a recess (40a) provided in the head (42) of the sleeve (40). In the part (41), a plurality of slits (47) are formed so as to open to the lower end along the axis.

Further, the screw hole (43) is formed at the upper end side from the middle of the slit (47), and the lower end side of the slit (47) has a structure in which the diameter is reduced via the arcuate portion (48). It has become.
In order to connect the protective plate (10) and the cushion member (11) with the push-turn rivet (4), the first and second through holes (30) and (33) formed in the two are communicated with each other. The cushion member (11) is placed at a predetermined position on the upper surface of the first protection plate (10a) of the protection plate (10), and the sleeve (11) is inserted into the second through hole (33) of the cushion member (11). 40) is inserted.
Then, the head (42) is housed in a substantially tight fit in the large-diameter hole (33b) of the second through hole (33), and the lower surface of the head (42) abuts against the auxiliary seat (3). , Is locked in the penetration prevention state.

Then, the shaft portion (41) of the sleeve (40) passes through the small diameter hole (33a) formed in the auxiliary sheet (3) and the small diameter hole (30a) of the first protective plate (10a), and the shaft portion (41 ) Reaches the inside of the large-diameter hole (30b) below.
