Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective member for a package, which is used for saving resources of a solid object having a certain shape such as gas-fired equipment or electric equipment as an object to be packaged, and its protective member. In particular, the present invention is suitably applied to a packaged object having a liquid flow path inside a water heater, a hot water heater, a water purifier, or the like.

[0002]

2. Description of the Related Art Conventionally, as a package protection member and a package, a combination of a cushioning member made of polystyrene foam (polystyrene foam) and a rectangular packing box made of cardboard has been generally known. In this apparatus, a cushioning material prepared so as to have an inner surface shape corresponding to the outer shape of the packaged object and an outer surface shape corresponding to the inner shape of the packing box is prepared, and the cushioning material is covered with the above-mentioned cushioning material. The package is housed in the packing box in a state of being fitted to the outside.

[0003]

However, in the above-mentioned conventional protective member for a package and the package, after the package is shipped from the manufacturing plant of the packaged product in the state of the package and the user unpacks the package, Both the cushioning material and the packing box are discarded as waste, which generates a large amount of garbage and may cause garbage pollution when processing the garbage. In addition, the cushioning material and the packing box are disposable because they are used only once as a package and are discarded, which presents a situation contrary to resource saving.

On the other hand, when the solid object as described above is used as the object to be packaged, it is not sufficient to cover the outer surface only with a covering material such as cardboard, and a cushioning material is used to provide a cushioning function against an external collision or the like. Because it is necessary to protect the packaged items,
In particular, there is a situation that the buffer material cannot be omitted even if it takes time to process the dust. On top of that, if the packaged object has a liquid flow path inside such as a water heater, for example, and it is necessary to circulate the liquid and perform a trial run before shipping from the factory, If the liquid is packaged with the liquid remaining and tilted in the distribution process from the factory to the user, the residual liquid may leak to the outside. In the case of leakage, the liquid may damage the packaging box due to the liquid, or impair the appearance.

[0005] The present invention has been made in view of such circumstances, and an object of the present invention is to omit a cushioning material, a packing box made of corrugated cardboard, and the like, and to make it possible to reuse as many times as a protective member. A protective member for a package and a package are provided. In addition, there is a problem that leakage does not cause any inconvenience.

[0006]

In order to achieve the above-mentioned object, the present invention forms the protective member as a synthetic resin molded body while having both a function of buffering the object to be packaged and a function of fixing the position of the object to be packaged. By doing so, the conventional cushioning material and packing box are omitted, and repeated use is possible while satisfying the function of protecting the packaged object and the measure against leakage of the residual liquid.

[0007] Specifically, the first member relating to the protective member for a package body.
The invention of the present invention is directed to a tray-shaped package protection member externally fitted from below to at least the bottom of a package having a flow path through which a liquid flows and a connection end to the flow path, and Items are added. That is,
A bottom wall, a peripheral wall surrounding the periphery of the bottom wall, an upward surface supporting the bottom surface of the bottom at a position above the lowest position of the bottom wall, and an outer peripheral surface of the bottom at a position inward of the peripheral wall And a horizontal surface portion for supporting the horizontal direction in a state where relative movement is restricted is formed of synthetic resin. And it is a specific matter that the upward surface portion and the horizontal surface portion are formed by a thin wall continuous from the bottom wall and the peripheral wall, respectively, with a space between the bottom wall and the peripheral wall.

In the case of the first invention, since the protective member is formed of a synthetic resin in the shape of a tray, even if the residual liquid leaks from the inside of the packaged object, the protective member is damaged or the appearance is reduced. There is no inconvenience that the appearance of the camera is impaired. In addition, the bottom surface of the bottom of the packaged object floats from the floor surface with a space between the bottom surface supported by the upwardly facing surface portion and the bottom wall contacting the floor surface, while the outer peripheral surface of the bottom portion of the packaged object. Is supported by the lateral surface portion and is supported with a space between the peripheral wall at the outer peripheral position thereof,
Prohibit the relative movement between the protective member and the packaged object while sufficiently protecting against external forces such as collision force from the floor surface and the outer peripheral side, and sufficiently fulfill the position fixing function of the packaged item. become. In addition, since the upward surface portion and the horizontal surface portion are formed of thin walls made of synthetic resin, the external force such as the above-mentioned collision force is elastically absorbed, and a sufficient cushioning function is also exerted. And it is possible to reuse not only once but also many times, which can greatly contribute to resource saving.

In the first aspect of the present invention, if a discharge hole is formed at an appropriate position on the bottom wall, even if the residual liquid leaks, the leaked liquid is discharged to the outside. It becomes possible. If the bottom of the package has a shape that is asymmetrical in the front-rear direction, the upward surface and the horizontal surface are disposed at asymmetric positions in the front-rear direction corresponding to the asymmetric shape, and the front and rear sides are identified with respect to the bottom wall. May be formed to have a shape corresponding to the identification symbol to be used. This makes it possible to easily recognize (discriminate) the front and rear of the protective member at a glance at the time of discharging the leaked liquid and fitting the protective member to the package. Examples of the above “identification symbol” include characters such as an arrow mark, “before” and “after”, and “Front”.

Further, in the first aspect of the present invention, a closing cap body for detachably closing the connection end of the article to be packaged may be provided. In this case, a holding portion for detachably holding the closing cap body is integrally formed on the bottom wall, and an engaging portion for detachably engaging with the holding portion is integrally formed on the closing cap body. It may be formed. In this way, the leakage of the residual liquid can be reliably prevented, and when the user unpacks the package and performs the installation work and the connection work with various pipes, the closing cap body is separated from the holding portion and the packaged object is separated. It is possible to carry out the work while keeping it closed at the connection end on the side.

The "synthetic resin" includes, for example, polyethylene (PE) or polypropylene (PP), or a foam thereof.

In a second aspect of the present invention, the package is formed in a tray shape from a bottom wall and a peripheral wall surrounding the bottom wall, and each of the ends is externally fitted to each end on both sides in one direction of the article to be packaged. With a pair of protection members for protecting the portion, for a package that is held integrally with the packaged object in a state where the pair of protection members are fitted to the respective ends of the packaged object, The following specific items are added. That is, as each of the protection members, a one-way support surface portion that supports the end surface of each of the end portions at a position inward of the bottom wall at the one-way outermost end position in the outer-fit state, and in the outer-fit state. The orthogonal direction supporting surface portion that supports the outer peripheral surface of each end portion in a state where the relative movement in the orthogonal direction is regulated at a position inward of the peripheral wall at the outermost end position in the direction orthogonal to the one direction is combined. It shall be formed of resin. In addition, it is a specific matter that the one-way support surface portion and the orthogonal direction support surface portion are formed by a thin wall continuous from the bottom wall and the peripheral wall, respectively, with a space between the bottom wall and the peripheral wall. Things.

The above-mentioned "one direction" is a direction which is determined according to circumstances such as the shape of the article to be packaged, such as a vertical direction or a horizontal direction. Each of the protection members is externally fitted. In the case of the horizontal direction, the protection members are externally fitted to, for example, both left and right end portions of the packaged object. In the case of the above-described vertical direction, the “one-way support surface portion” of the lower protection member is the first direction.
The “upward surface portion” in the invention of the first aspect, and the “orthogonal support surface portion” becomes the “lateral surface portion” in the first aspect.

In the case of the second aspect of the invention, for example, an example in which the above "one direction" is defined as a vertical direction will be described. On the lower protective member side, the lower surface (bottom) of the lower end (bottom) of the packaged object The bottom surface) is supported by the one-way support surface portion and floats from the floor surface with a space between the bottom wall and the bottom wall contacting the floor surface, while the outer peripheral surface of the lower end portion of the packaged object is supported in the orthogonal direction. It is supported by the surface portion and is supported with a space between it and the peripheral wall at the outer peripheral position. Also on the side of the upper protection member, the upper surface (top surface) of the upper end of the packaged object is supported by the one-way support surface portion and is covered by the bottom wall at an upper position with a space therebetween, The outer peripheral surface of the upper end portion of the packaged object is supported by the orthogonal support surface portion, and is supported with a space between the outer peripheral surface and the peripheral wall at the outer peripheral position. As a result, the relative movement between each protective member and the packaged object is prohibited while being sufficiently protected against external forces such as collision forces from the floor side, the upper side, and the outer peripheral side, and the position of the packaged object is prevented. It will fulfill the fixed function sufficiently.
In addition, since the one-way support surface portion and the orthogonal direction support surface portion are formed by thin walls made of synthetic resin, the elastic member can elastically absorb the external force such as the above-described collision force and also exhibit a sufficient cushioning function. Become. Moreover, similar to the first invention, repeated use (returnable) is possible not only once but also as many times as possible, resulting in remarkable resource saving as compared with the conventional disposable case.

[0015] In the second aspect of the present invention, it is preferable that the peripheral wall of each protective member is formed so as to be inclined obliquely outward with respect to one direction so as to be separated from the object to be packaged toward the outer periphery. This allows
The distance between the packaged object and the tip of the peripheral wall becomes larger,
The space width between the support member and the orthogonal direction supporting surface is also larger. For this reason, even at the time of collision with another object, the tip of the peripheral wall comes into contact first, and the buffering function by the space and the buffering function by elastic absorption are both enhanced.

The above-mentioned "pair of protective members" are preferably formed to have the same shape as each other and to be overlapped with each other. To do this, for example,
Among the surfaces constituting the protection member, a surface extending in one direction may be inclined so as to expand toward the opening. Thereby, after the package is delivered and the user unpacks the package, it can be compactly stacked when the package is collected at a manufacturing factory or the like for reuse.

In addition, of the above “a pair of protective members”,
It is preferable that at least one of the protective members is formed with a handle portion for transportation. Thus, even if the packaged object is relatively heavy (for example, 10 to 25 kg), it can be laterally held (slightly moved) in a packaging line of a manufacturing factory, stored, and loaded / unloaded during transportation by a transportation vehicle. In such cases, it can be easily handled by one worker. As the above-mentioned "concave handle part", for example, a recess or a through hole for inserting an operator's hand is formed in a part of the peripheral wall, or a part of an edge of the peripheral wall is cut away. What is necessary is just to form it in a shape. In addition, you may form the convex part for hanging a hand.

In order for the pair of protective members to be held integrally with the packaged object in a state where the pair of protective members are fitted to the respective ends of the packaged object, shrink packaging technology is applied. For example, heat shrink in a state of covering at least both protective members by tying them with a heat shrinkable film and closely contact the two protective members, tying around the two protective members with a tying string, or a heat shrinkable film and What is necessary is just to use together with the binding with a binding string. When using the above heat-shrinkable film, the pair of protective members are externally fitted to each end of the article to be packaged, and are entirely covered with a tubular, bag-like or sheet-like heat-shrinkable film. What is necessary is just to heat-shrink the heat-shrinkable film so that the heat-shrinkable film is brought into close contact with the outer surfaces of the pair of protective members. In the case of using the above-described binding strap, a PP band (polypropylene band) is used so that each of the protective members is pressed against the object to be packaged in a state where the pair of protective members are fitted to the respective ends of the object to be packaged. ) And the like. Further, when the heat-shrinkable film and the tying string are used together, they are first tied as described above with the tying string, covered with the heat-shrinkable film as described above so as to include the tied tying string, and thermally shrunk. I just need.

When the protective member is covered with the heat-shrinkable film, the inner wall of the heat-shrinkable film stretched between the two protective members is formed by inclining the peripheral wall of the protective member outwardly as described above. It is possible to further increase the interval of the gap formed between the outer surface of the intermediate portion of the package and the outer surface of the package. As a result, even if an external collision or the like occurs, a large deformation margin is secured in the film by the amount of the gap, and a protective function / buffer for preventing scratches and dents in the intermediate portion of the packaged object. The function can be more reliably improved.

The above-mentioned "heat-shrinkable film" may be any film as long as it exhibits shrinkage by heating or cooling after heating, and preferably has flexibility even after heat-shrinking. For example, those mainly composed of polyolefins, and more specifically, low-density polyethylene,
A laminated film in which any one kind of a single layer or plural kinds of polypropylene, ethylene, vinyl acetate copolymer and the like are laminated, or a film composed of these resin compositions is exemplified. The film may be opaque, but is preferably translucent or transparent so that the contents to be packaged can be visually confirmed.

Further, in order to hold only the heat-shrinkable film without using the tying string, the tensile strength of the film in the direction connecting the pair of protective members must be equal to or greater than the own weight of the packaged object. Just set it. Thereby, even when the object to be packaged is heavy even when the object is transported by holding the lower end portion of the upper protective member, the weight of the object to be packaged is securely supported by the film, and the material is transported. Work can be performed reliably. For example, when a low-density polyethylene film material is used as the heat-shrinkable film, if the instantaneous water heater with its own weight of 20 kg is to be packaged, the safety factor is expected if the film thickness before heat shrinkage is about 80 μm or more. However, the object to be packaged can be sufficiently held. In the case of using a tying strap together, it is possible to reduce the film thickness of the film by the withstand load that the tying strap bears. Since the film is thermally contracted and adhered in a state where the tying string is included, the gap between the above-described inner surface of the film and the outer surface of the intermediate portion of the packaged object is wider than that without the tying string, thereby providing a protection function. -The buffer function can be further improved.

Furthermore, in a case where the holding member is held only by the heat-shrinkable film without using the binding strap, a pair of protection members are fitted to both ends in the horizontal direction such as left and right sides or front and rear sides of the article to be packaged. In this case, since the weight of the packaged object is supported by both holding members, the function of the film is that the pair of protection members and the packaged object only have to be integrally held so as not to come off. . For this reason, the film thickness does not require a tensile strength that can withstand the weight of the packaged object as in the case of disposing the pair of protective members above and below, and a thinner film is sufficient.

In the case where the above-mentioned means for integrally holding the pair of protective members and the packaged object is adopted, one or more of the following various specific items are selectively or additionally added. You may do so.

That is, the first specific matter is to form a step-shaped regulating portion for preventing the heat-shrinkable film from shifting in one direction in the protective member. This effectively prevents the film from being shifted in one direction after the heat shrinkage, and in addition to the protective coating function of the package by the film, supports the packaged product particularly when a pair of protective members are arranged vertically. Can be performed reliably. As the above-mentioned "step-shaped regulating portion", a step-shaped uneven portion, a simple projection, a convex portion having a corner, or
A concave or convex step may be used. Further, the formation position may be any position of the bottom wall and the peripheral wall, but the bottom wall position near the corner edge transitioning from the bottom wall to the peripheral wall is preferable, and particularly the vicinity of the corner edge and the four corner positions of the bottom wall Is more preferred.

As a second specific matter, in the case where the protective member is covered with the heat-shrinkable film, the corners of the protective member, which are located on the side in contact with the floor surface, are separated from the floor surface and are not separated from the floor surface. That is, a non-contact portion having a shape that makes contact. Thereby, when covered with a heat-shrinkable film and adhered by heat shrinkage, the film in close contact with the non-contact portion is prevented from being in contact with or rubbing with the floor surface, and the film caused by rubbing or the like is prevented. The occurrence of damage such as tearing can be reliably avoided. Since the non-contact portion is formed at a corner where the influence of rubbing or the like is particularly concentrated, the occurrence of the damage can be effectively avoided. Therefore, the above-mentioned non-contact portion may be formed not only on the corner but also on the entire periphery of the corner on the side in contact with the floor surface of the protective member. The “non-contact portion” may have a concave shape, a convex round shape or a concave round shape.

As a third specific matter, a position holding portion for restricting movement of the binding strap in a direction perpendicular to the longitudinal direction is formed on at least a part of a portion of the protection member which comes into contact with the binding strap. . This prevents the bound strap from being displaced from its bound state, and can maintain a secure bound state. As the above-mentioned "position holding portion", a restriction wall for preventing movement of the binding strap may be formed at a position adjacent to the binding strap in the direction perpendicular to the binding strap. What is necessary is just to form a concave groove or a through-hole which lets a binding string pass. In the case of a concave portion or a concave groove, the cross section may be formed in a C-shape to ensure prevention of detachment. Alternatively, the above-mentioned regulating wall may be formed by a convex portion or a convex ridge.

A fourth specific matter is that a groove is formed in a portion of the protective member on the side in contact with the floor surface along a portion where the tying string extends so that the tying string can be immersed in the entire length. It is. Thereby, even when the package is installed on the floor via the protection member, the binding strap is prevented from coming into contact with the floor, and the package is dragged along the floor. It is possible to reliably avoid the occurrence of damage to the tying string due to friction with the floor surface, etc., and to maintain a reliable tying state.

[0028]

As described above, according to the first aspect of the present invention relating to the protective member for a package or the second aspect of the present invention relating to the package, the conventional cushioning material and the packaging box are both omitted to provide one package. The protective member can exert all of the functions of buffering, protecting, and maintaining the position of the packaged object. In addition, after the conventional disposables are discarded and the packaging is unpacked, if they are collected, they can be used again and again as many times as possible, and remarkable resource saving and efficiency can be achieved. In addition, even if the packaged object has a possibility of leakage of the residual liquid in the delivery process, it is possible to avoid inconvenience caused by the leakage and to reliably maintain the above functions.
