Description

  The present invention relates to a protective member for a packaging body used to save resources by using a solid object having a certain shape such as gas combustion equipment or electric equipment as a packaged article, and a packaging body using the protective member, In particular, the present invention is suitably applied to an article to be packaged having a liquid flow path inside a water heater, a hot water heater or a water purifier.

  2. Description of the Related Art Conventionally, as a protective member for a packaging body and a packaging body, a combination of a foamed polystyrene (polystyrene foam) cushioning material and a corrugated rectangular packaging box is generally known. In this case, a cushioning material prepared so as to have an inner surface shape corresponding to the outer surface shape of the package and an outer surface shape corresponding to the inner surface shape of the packaging box is prepared. It is made to store in the said packaging box in the state externally fitted with respect to the package.

  However, in the above-described conventional protective member for a package and package, after the package is shipped from the manufacturing plant of the packaged goods and the packaging is unpacked by the user, both the cushioning material and the packaging box are unnecessary. As a result, a large amount of trash is generated, and there is a risk of causing trash pollution when processing the trash. In addition, since the cushioning material and the packing box are used only once as a package and are discarded, the situation is contrary to resource saving.

  On the other hand, when a solid object as described above is to be packaged, it is not sufficient to cover the outer surface with a coating material such as cardboard, etc., and the buffered material is used to provide a buffering function against collisions from outside and the like. Therefore, there is a circumstance that the cushioning material cannot be omitted even if it takes time to dispose of dust. In addition, if the article to be packaged has a liquid flow passage inside, such as a water heater, and it is necessary to perform a trial run by circulating the liquid before shipment from the factory, If the liquid is packaged with the liquid remaining in the container and tilted in the distribution process from the factory to the user, the residual liquid may leak to the outside. And when it leaks out, the packaging box will get wet and be damaged by the liquid, and the appearance will be impaired.

  The present invention has been made in view of such circumstances, and its purpose is for a packaging body that can be reused as many times as a protective member by omitting a cushioning material, a cardboard packaging box, and the like. It is providing a protection member and a package. In addition, there is no inconvenience even if the residual liquid leaks out.

  In order to achieve the above-mentioned object, the present invention forms a protective member as a synthetic resin molded body, while having a buffer function for a package and a function for fixing the position of the package together. The material and the packaging box are omitted, and the repetitive use is made possible while satisfying the protection function for the package and the countermeasure for leakage of the residual liquid.

  Specifically, the first invention relating to the protective member for a package body is a tray that is externally fitted from the bottom to at least the bottom of a packaged article having a flow passage through which a liquid flows and a connection end to the flow passage. The following specific items are added to the protective member for the package. That is, a bottom wall, a peripheral wall surrounding the periphery of the bottom wall, an upward surface portion that supports the bottom surface of the bottom portion at a position above the lowest position of the bottom wall, and a position of the bottom portion at an inner side position than the peripheral wall. A laterally facing portion that supports the outer peripheral surface in a state in which relative movement in the horizontal direction is restricted is formed of a synthetic resin. And it makes it a specific matter to shape | mold the said upward surface part and a horizontal surface part in the state which left the space between the said bottom wall and the surrounding wall by the thin wall which continues from the said bottom wall and the surrounding wall, respectively.

  In the case of the first invention, since the protective member is formed in a tray shape from the synthetic resin, even if the residual liquid leaks from the inside of the package, the protective member may be damaged or the appearance may be improved. There will be no inconvenience of damage. Moreover, the bottom surface of the bottom of the packaged object is supported by the upward surface part and is in a state of floating from the floor with a space between the bottom wall and the bottom wall contacting the floor, while the outer peripheral surface of the bottom of the packaged object Is supported by a laterally facing surface part with a space between it and the peripheral wall at the outer peripheral side position, and is sufficiently protected against external forces such as a collision force from the floor side and the outer peripheral side. Thus, the relative movement between the protective member and the packaged object is prohibited, and the position fixing function of the packaged object is sufficiently achieved. In addition, since the upward surface portion and the lateral surface portion are formed of a thin wall made of synthetic resin, an external force such as the collision force is elastically absorbed to exhibit a sufficient buffer function. In addition, it can be reused not only once but also many times, which can greatly contribute to resource saving.

  In the first aspect of the invention, if a discharge hole is formed at an appropriate position on the bottom wall, the leaked liquid can be discharged to the outside even if the residual liquid leaks. become. If the bottom of the package has an asymmetric shape in the front-rear direction, the upward surface and the lateral surface are arranged at an asymmetric position in the front-rear direction corresponding to the asymmetric shape, and the front and back are identified. You may make it form the through-hole of the shape corresponding to the identification symbol for doing. Thereby, the discharge | emission of said leakage liquid and the identification (discrimination) before and behind a protection member at the time of the operation | work which externally fits a protection member to a to-be-packaged object are attained easily. Examples of the “identification symbol” include arrows, characters such as “front”, “rear”, and “Front”.

  Furthermore, in the said 1st invention, you may make it have a closing cap body which detachably closes the connection edge part of a to-be-packaged item. In this case, a holding portion for detachably holding the closing cap body is integrally formed on the bottom wall, while an engaging portion that is detachably engaged with the holding portion is integrally formed on the closing cap body. What is necessary is just to form. As a result, leakage of residual liquid can be surely prevented, and when the user unpacks and performs installation work and connection work with various pipes, the closure cap body is separated from the holding part to be packaged. It is possible to work with the connection end portion on the side being closed.

  Examples of the “synthetic resin” include polyethylene (PE) or polypropylene (PP), or foams thereof.

  The second invention according to the packaging body is formed in a tray shape from the bottom wall and the peripheral wall surrounding the periphery of the bottom wall, and is externally fitted to each end portion on one side of the package to protect each end portion. For a package body that is held integrally with the package object in a state in which the pair of protection members are fitted around the end portions of the package object, the following specification is provided. Items are added. That is, as each of the protective members, in the outer fitting state, in the outer fitting state, the one-way support surface portion that supports the end surface of each end portion at a position on the inner side of the bottom wall of the one-way outermost end position; Combined with the orthogonal support surface portion that supports the outer peripheral surface of each end portion in a state in which relative movement in the orthogonal direction is restricted at a position on the inner side of the peripheral wall of the outermost end position in the direction orthogonal to the one direction. It shall be formed of resin. In addition, it is a specific matter to form the unidirectional support surface portion and the orthogonal support surface portion 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. Is.

  The above "one direction" is a direction determined according to circumstances such as the shape of the package in the vertical direction or the horizontal direction, and in the case of the vertical direction, protective members are respectively provided on the upper and lower ends of the package. In the case of the horizontal direction, for example, the protective members are respectively fitted to the left and right ends of the package. In the case of the above vertical direction, the “one-directional support surface portion” of the lower protective member becomes the “upward surface portion” in the first invention, and the “orthogonal support surface portion” is the “laterally-oriented surface portion” in the first invention. Become.

  In the case of the second invention, for example, an example in which the above-mentioned “one direction” is the vertical direction will be described. On the lower protection member side, the lower surface (bottom surface) of the lower end portion (bottom portion) of the package is While being supported by the unidirectional support surface and spaced from the floor contacting the floor, the outer peripheral surface of the lower end of the package is supported by the orthogonal support surface. Thus, it is supported with a space between it and the peripheral wall at the outer peripheral side position. On the side of the upper protective member, the upper surface (top surface) of the upper end portion of the package is supported by the unidirectional 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 article to be packaged is supported by the orthogonal support surface portion and is supported with a space between the peripheral wall at the outer peripheral side 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 a collision force from the floor side, the upper side and the outer circumferential side, and the position of the packaged object is prohibited. It will perform the fixed function sufficiently. In addition, since the one-directional support surface portion and the orthogonal-direction support surface portion are formed of a thin wall made of synthetic resin, the external force such as the collision force is elastically absorbed to exhibit a sufficient buffer function. Become. In addition, as in the first aspect of the invention, it is possible to repeatedly use (returnable) until it is broken not only once but also many times, and the resource can be saved significantly compared to the conventional disposable case.

  In the second aspect of the invention, it is preferable that the peripheral wall of each protection member is formed so as to be inclined obliquely outward with respect to one direction and away from the packaged object toward the outer peripheral side. Thereby, the space | interval of the to-be-packaged object and the front-end | tip position of a surrounding wall becomes larger, and the space width between orthogonal direction support surface parts also becomes larger. For this reason, the tip of the peripheral wall comes first in the event of a collision with another object, and the buffer function by the space and the buffer function by elastic absorption are both enhanced.

  The “pair of protective members” is preferably formed in the same shape as each other and can be overlapped with each other. In order to do this, for example, a surface extending in one direction among the surfaces constituting the protective member may be inclined so as to expand toward the opening side. Thus, after the package is delivered and the user unpacks the package, it can be compactly stacked when collected in a manufacturing factory or the like for reuse.

  In addition, it is preferable to form a carrying handle for at least one of the “a pair of protective members”. As a result, even if the packaged item is relatively heavy (for example, 10 to 25 kg), it can be held sideways (slightly moved) in the packaging line of the manufacturing plant, stored, and loaded and unloaded during transport by a transport vehicle. Thus, it can be easily handled by one worker. As the above-mentioned “concave handle”, 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 the edge of the peripheral wall is notched What is necessary is just to make it form in a shape. In addition, you may form the convex part for putting a hand.

  In order to make the above-mentioned “a pair of protective members are held integrally with the packaged object in a state of being fitted around the ends of the packaged object”, for example, by applying shrink wrapping technology, Heat-shrink in a state of covering at least both protective members with a shrinkable film so that they are in close contact with the two protective members, bind around the two protective members with a binding string, or with a heat-shrinkable film and a binding string What is necessary is just to perform together with unity. When using the above heat-shrinkable film, the whole is covered with a tubular, bag-like, or sheet-like heat-shrinkable film in a state in which a pair of protective members are externally fitted to each end of the package, The heat-shrinkable film may be heat-shrinked so as to be in close contact with the outer surfaces of the pair of protective members. Further, when the above-described binding string is used, a PP band (polypropylene band) is provided so that each protective member is pressed against the package in a state in which the pair of protective members are externally fitted to each end of the package. ) Or the like may be stretched and bound. Furthermore, when using a heat-shrinkable film and a binding string in combination, first, the bundled string is bound as described above, and the heat-shrinkable film is covered and heat-shrinked as described above so as to enclose the bundled binding string. That's fine.

  And when covering with a heat-shrinkable film, the inner wall of the film after heat-shrinking spanned between the two protective members and the packaged object are inclined by inclining the peripheral wall of the protective member outward as described above. It is possible to further increase the gap formed between the outer surface of the intermediate portion and being separated from each other. As a result, even if a collision from the outside occurs, a large deformation margin for the gap is secured on the film, and a protective function / buffer that prevents scratches, dents, etc. in the intermediate portion of the package The function can be improved more reliably.

  The “heat-shrinkable film” is not particularly limited as long as it exhibits shrinkability by heating or cooling after heating, and preferably has flexibility even after heat shrinkage. For example, those based mainly on polyolefins are mentioned, more specifically, a laminated film in which one kind of single layer or plural kinds of low density polyethylene, polypropylene, ethylene, vinyl acetate copolymer, etc. are laminated, Or the film which consists of these resin compositions is mentioned. The film may be opaque, but is preferably translucent or transparent so that the contents to be packaged can be visually confirmed.

  Moreover, in order to hold only with a heat-shrinkable film without using a binding string, if the tensile strength of the film in the direction of tying a pair of protective members is set to have a value equal to or greater than the weight of the article to be wrapped. Good. Thereby, when carrying and carrying the hand to the lower end part of the upper protection member, even if the article to be packaged is a heavy article, the weight of the article to be packaged is reliably supported by the film and carried. It is possible to reliably perform the work. For example, when a low-density polyethylene film material is used as a heat-shrinkable film, a safety factor is expected if the film thickness before heat-shrinkage is about 80 μm or more if an instantaneous water heater with a self-weight of 20 kg is used as the package. However, the packaged item can be sufficiently held. When using a cable tie together, it is possible to reduce the film thickness by the load resistance of the cable tie, reducing the cost of the film material, Since the film is heat-shrinked in a state of containing the binding string, the gap between the inner surface of the film and the outer surface of the intermediate part of the package is wider than that without the binding string, and a protective function. -The buffer function can be further improved.

  Furthermore, in the case of holding only with a heat-shrinkable film without using a binding string, and when a pair of protective members are externally fitted to the left and right sides or both front and rear side ends of the package, etc. In other words, since the weight of the article to be packaged is supported by both holding members, the function of the film is only to be able to hold the pair of protective members and the article to be packaged together so that the pair of protection members and the article to be packaged do not come off. For this reason, the film thickness of the film does not require a tensile strength that can counter the weight of the packaged object as in the case where the pair of protective members are arranged above and below, and a thinner film is sufficient.

  When adopting a means for integrally holding the pair of protective members and the article to be packaged, one or more of various specific items shown below may be selectively added or all of them may be added. Also good.

  That is, the first specific matter is to form a step-shaped restricting portion that prevents the heat-shrinkable film from shifting in one direction with respect to the protective member. This effectively prevents the film from shrinking in one direction after heat shrinkage, and in addition to the protective covering function of the object to be packaged by the film, in particular, support of the object to be packaged when a pair of protective members are arranged vertically. Can be performed reliably. As the above “step-shaped restricting portion”, a step-shaped uneven portion, a simple protrusion, a convex portion having a corner, a concave or convex step portion, or the like may be adopted. In addition, the formation position may be any position of the bottom wall and the peripheral wall, but the bottom wall position in the vicinity of the corner edge transitioning from the bottom wall to the peripheral wall is preferable, and particularly in the vicinity of the corner edge and the four corner positions of the bottom wall. Is more preferable.

  As a 2nd specific matter, when covering with a heat-shrinkable film, the corner | angular part which exists in the site | part of the corner | angular part of a protective member and which contacts a floor surface leaves | separates from the said floor surface, and becomes non-contact. The shape is a non-contact portion. As a result, when the film is covered with a heat-shrinkable film and adhered by heat shrinkage, the film adhered to the non-contacting portion is prevented from coming into contact with or rubbing against the floor surface. The occurrence of damage such as tearing can be reliably avoided. Since the non-contact portion is formed at the corner portion where the influence of rubbing or the like is particularly concentrated, the occurrence of the damage can be effectively avoided. Therefore, you may form said non-contact part not only a corner | angular part but the perimeter of the corner | angular edge part of the side which contacts the floor surface of a protection member. The “non-contact portion” may be a concave shape or a convex or concave curved surface shape.

  A third specific matter is to form a position holding portion that restricts movement of the protective member in the direction orthogonal to the longitudinal direction of the binding member at least at a part of the portion of the protective member that contacts the binding cord. Thereby, it is prevented that the bundled binding string is displaced from the binding state, and a reliable binding state can be maintained. As the “position holding portion”, it is only necessary to form a regulating wall that prevents the binding string from moving at a position adjacent to the binding string in the orthogonal direction. What is necessary is just to form a through-hole which lets a ditch | groove or a binding string pass. In the case of a recess or groove, the cross-sectional shape may be C-shaped to ensure prevention of disengagement. Or you may make it form said regulation wall by a convex part or a protruding item | line.

  As a fourth specific matter, a concave groove having a depth capable of immersing the binding string is formed over the entire length, along a part where the binding string extends, in a part of the protective member that contacts the floor surface. Thereby, even if it is a case where a packaging body is installed in a floor surface via the said protection member, it is avoided that a binding string contacts the said floor surface, and a packaging body is twisted along a floor surface. Thus, it is possible to reliably avoid the occurrence of damage to the binding string due to rubbing with the floor surface, etc., and to maintain a reliable binding state.

  As described above, according to the first invention relating to the protective member for a packaging body or the second invention relating to the packaging body, the conventional cushioning material and the packaging box are both omitted, and packaging is performed with one protective member. All of the buffering function, the protection function, the position holding function and the like for the object can be exhibited. In addition, after the conventional disposable is discarded and the packaging is unwound, it can be reused any number of times and can be remarkably resource-saving and efficient. Moreover, even if the packaged item has a risk of leakage of the residual liquid during the delivery process, it is possible to avoid the inconvenience due to the leakage and to reliably maintain the above functions.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
FIG. 1 shows a protective member and a package according to a first embodiment of the present invention, where 1 is a product as a packaged object, and 2 and 2 are externally fitted to the upper and lower ends with the vertical direction of the product 1 as one direction. Protective trays made of synthetic resin as a pair of protective members, PP bands 3 and 3 as binding strings, and 4 a film after heat shrinking using a heat shrinkable film. In the drawings shown below, the thickness of the film 4 is exaggerated from the actual thickness because of the illustrated relationship.

  The product 1 is an instantaneous water heater, in which a device main body is housed in a metal casing 11 which is vertically long as shown in FIG. Accordingly, the protective members 2 are externally fitted to the upper and lower ends of the housing 11 from the vertical direction. Although the apparatus main body is not shown, a heat exchanger, a combustor for heating the heat exchanger, a water inlet pipe for supplying tap water to the heat exchanger, and hot water heated by the heat exchanger are provided. The main element is the tapping pipe that drains the hot water. In FIG. 2, 12 is a joint flange of the housing 11, 13 is an exhaust port, 14 is a connection end of the water intake pipe, 15 is a connection end of the hot water discharge pipe, and 16 is a connection end of a gas supply pipe to the combustor. The connection end portions 14, 15, and 16 protrude from the lower surface of the housing 11 to the outside.

  The protective trays 2 and 2 are formed in the same shape. As shown in FIGS. 3 to 5 in addition to FIG. 1, each protection tray 2 opens to one side (upward in the illustrated example), and has a substantially rectangular bottom wall 21 and a diagonally outward from the periphery of the bottom wall 21. The peripheral wall 22 rising in an inclined state so as to gradually expand is integrally formed by synthetic resin molding. The bottom wall 21 is substantially similar to the planar shape (the shape of the lower surface and the upper surface) of the product 1 and has a rectangular shape that is larger by a predetermined amount. The peripheral wall 22 has relatively long side walls 23, 23 and a relatively short side wall 24. , 24. Each corner 25 connecting the adjacent side walls 23 and 24 is formed by a curved surface having a predetermined radius of curvature. Both the bottom wall 21 and the peripheral wall 22 are formed of a predetermined thin wall.

  On opposite side walls 23, 23 (see FIGS. 3 and 4), a portion near the corner 25 is recessed inward to form recesses 26, 26 on the outer surface side, while on the inner surface side. A stepped step portion is formed to form a vertical support surface portion 27a as a unidirectional support surface portion or an upward surface portion, and a horizontal support surface portion 27b as an orthogonal support surface portion or a lateral surface portion. In addition, a concave groove portion 28 into which the joining flange 12 of the product 1 enters is also formed in the vertical support surface portion 27a on the front side wall 23 side. In addition, passage portions 29 and 29 as position holding portions of the PP band 3 are respectively formed on the front end edges of the both side walls 23 and 23 while being recessed inward and recessed toward the bottom wall 21. The bottom wall 21 is formed with inward grooves 30 and 30 as concave grooves through which the PP band 3 passes.

  Further, in the opposite side walls 24, 24 (see FIGS. 3 and 5), the central portion is recessed inward and a recess 31 is formed on the outer surface, respectively, A vertical support surface portion 32a as a unidirectional support surface portion or an upward surface portion and a horizontal support surface portion 32b as an orthogonal direction support surface portion or a lateral surface portion are formed on the side. In addition, a concave carrying handle 33 is formed at the front edge of the side walls 24, 24.

  Furthermore, a through hole 34 having the same shape as an arrow symbol as an identification symbol indicating the front-rear direction of the protective member 2 is formed in the bottom wall 21, and the side indicated by the arrow is the front side where the concave groove portion 28 into which the joining flange 12 enters is provided. It is to be identified. In addition, both side portions including the two corners of the bottom wall 21 (see FIG. 1) are formed with a step on the inner side with respect to the flat surface 21b of the central portion, and non-contact portions 21a, 21a In the lower protection tray 2, the film 4 covering each non-contact portion 21a is not in contact with the floor surface G (see FIG. 4).

  Each of the above protection trays 2 is formed such that the surfaces extending in the vertical direction are slightly inclined, and can be stacked in a state of being compactly stacked in the vertical direction.

  In the package having the above structure, the lower end portion of the product 1 is fitted into the vertical support surface portions 27a and 32a and the horizontal support surface portions 27b and 32b of the lower protection tray 2 from above, and the upper end of the product 1 in this state. The upper protection tray 2 is similarly externally fitted with the top and bottom reversed. In this state, the two PP bands 3 and 3 are respectively passed through the passage groove 30 and the passage portions 29 and 29 of the lower protection tray 2, and the passage groove 30 and the passage portions 29 are similarly applied to the upper protection tray 2. , 29, respectively, and fastening by fasteners or fastening by welding is performed. Thereafter, the tubular heat-shrinkable film material is passed in the vertical direction to cover the whole and heat-shrink. Thereby, the shrink opening 41 of the film 4 is formed at the center position of the flat surface 21b of each of the upper and lower protection trays 2, and the film 4 between the upper and lower protection trays 2 and 2 is formed between the outer surface of the intermediate portion 17 of the product 1 and the film. 4 is contracted in a state where a gap 42 (see FIG. 4) and a gap 43 (see FIG. 5) remain between the inner surfaces of the four.

  In such a package, the upper and lower ends of the product 1 are supported by the vertical support surface portions 27a and 32a of the protection tray 2 in a state of being spaced apart from the bottom wall 21 in the vertical direction, while being supported in the horizontal direction. The surface portions 27b and 32b are supported in a state in which a space is horizontally separated from the side walls 23 and 24. For this reason, even if a collision force with other external objects acts on the bottom wall 21 or the peripheral wall 22, a sufficient bending allowance due to elastic deformation of the bottom wall 21 and the peripheral wall 22 is ensured, and the collision force is cushioned. It will be elastically absorbed in the state of adding. Thereby, a buffer function and a protective function are fully exhibited.

  In addition, if each protective tray 2 is collected after the packaging body is delivered from the factory to the user and the packaging is unwound, the protective tray 2 can be used repeatedly.

  Further, even if residual water leaks from the connection end portions 14 and 15 of the product 1, the protective tray 2 is not damaged by wetting, and the leaked water can be discharged from the through hole 34 to the outside.

Each of the protection trays 5 opens upward as shown in the lower side in FIGS. 7 and 8, and includes a bottom wall 51 and four inner side walls 52, 52, 53, 53 that rise from the periphery of the bottom wall 51. The upper bank-like upper peripheral wall 54 and the peripheral wall 55 inclined outwardly so as to gradually expand obliquely downward from the upper peripheral wall 54 are each integrally formed by a thin wall. is there. That is, each of the protective trays 5 has a double wall structure having a space 56 (see FIG. 8) defined by the inner side walls 52, 52, 53, 53, the upper peripheral wall 54, and the peripheral wall 55. Is.

  A step portion is formed on each of the inner side walls 52, 53, and by this step portion, a vertical support surface portion 57 a as a unidirectional support surface portion or an upward surface portion, and a horizontal support surface portion 57 b as an orthogonal direction support surface portion or a lateral surface portion, Is formed. In addition, a concave groove portion 58 into which the joining flange 12 of the product 1 enters is also formed in the vertical support surface portion 57a on the inner wall 52 side on the front side.

  Passing portions 59 and 59 serving as position holding portions for the PP band 3 are respectively recessed at the lower ends of the two opposing walls in the peripheral wall 55 and recessed above the lower end edge. In the bottom wall 51, passage grooves 60, 60 as concave grooves through which the PP band 3 passes are formed to be recessed inward. Further, on the other two opposite walls of the peripheral wall 5, a carrying handle 61 is formed as a through hole.

  A through hole 62 having the same shape as an arrow symbol as an identification symbol indicating the front-rear direction of the protective member 5 is formed in the bottom wall 51, and the side indicated by the arrow is the front side with the concave groove portion 58 into which the joining flange 12 enters. It is supposed to be identified. In addition, the four corners at the lower end of the peripheral wall 55 (see FIG. 1) are formed with a step on the upper side of the lower end edge to form non-contact portions 63, 63,.
