Description

  The present invention relates to a package and a packaging method.

  Conventionally, a sales form in which a product is ordered by telephone or the like and delivered to the orderer by mail is performed. Today, due to the spread of the internet, the desired product is ordered from the internet, and the product is delivered to the orderer by mail. Many forms of sales are being used.

  The ordered product is mailed in a state where the product is packaged so as not to be broken. As such a package, for example, Patent Document 1 discloses an outer cylinder having at least one side opened, and the outer cylinder. There has been proposed a packaging body for transportation and the like, which is composed of an inner bag body with an injection valve that is inserted and filled with a packaging body to hold the packaging body.

  The packaging body provides a cushioning property to the inner bag body by filling the inner bag body with an injection valve, and the cushioning body protects the package body from an impact during transportation. It is configured to prevent damage.

  However, as described above, since the packaging body provides cushioning to the inner bag body with an injection valve by filling the inner bag body with an injection valve, an excessive pressing force is applied during transportation. Since there is no escape path for the gas in the inner bag body with the injection valve, the inner bag body with the injection valve may rupture, and the inner bag body with the injection valve may instantly lose the cushioning property and the packaged body may be damaged. Has the problem.

  Furthermore, the outer cylinder of the package and the inner bag with the injection valve are no longer necessary after the product has been delivered to the orderer, and are discarded, and are not preferred from the viewpoint of global environmental protection in recent years. There is also a need to reduce things.

JP-A-5-4664

  The present invention provides a package and a packaging method capable of reliably protecting an object to be packaged from an impact during transportation and transporting the object without damaging the object to be packaged.

  The package of the present invention comprises an upper and lower foam formed on a sandwiching surface with a facing surface sandwiching the packaged object, the packaged article held between the sandwiching surfaces of the upper and lower foams, and the upper and lower foams. And a heat shrink film that is covered and fastened in a direction in which the clamping surfaces are in close contact with each other.

  The packaging body is characterized in that convex portions are formed on the sandwiching surfaces of the upper and lower foams. In the above package, a plurality of convex portions are formed in a grid pattern vertically and horizontally on the sandwiching surfaces of the upper and lower foams.

  Furthermore, in the packaging body, the shape-retaining sheet is disposed on the lower surface of the lower foam so as to protrude from both end edges of the upper and lower foams, and the heat shrink film faces both end edges of the upper foam. It is stretched between the edge portions of the shape-retaining sheet in a tensioned state, and the tensioned heat-shrink film clamps the upper and lower foams in a direction in which these sandwiching surfaces are in close contact with each other. Features.

  In the packaging body, the upper and lower foams can be used as a cleaning tool.

  The packaging method of the present invention forms a laminated body by superposing upper and lower foams having a sandwiching surface for sandwiching a packaged object in a state where the sandwiched surfaces face each other and with the packaged object interposed therebetween. The laminated body is surrounded by a heat-shrinkable film, and then the heat-shrinkable film is heated and shrunk so that the upper and lower foams are clamped by the heat-shrinkable film and are wrapped on the sandwiching surfaces of the upper and lower foams. It is characterized by pinching and concealing objects.

  The package of the present invention comprises an upper and lower foam formed on a sandwiching surface with a facing surface sandwiching the packaged object, the packaged article held between the sandwiching surfaces of the upper and lower foams, and the upper and lower foams. And a heat shrink film that is fastened in a direction in which the sandwiching surfaces are in close contact with each other. Therefore, the package is held between the sandwiching surfaces of the upper and lower foams, and external forces applied during transportation are applied to the upper and lower foams. Will surely absorb and the package will not be damaged during transportation.

  And since the article to be packaged is held by being clamped by the clamping surfaces of the upper and lower foams, it is not necessary to form a storage recess corresponding to the article to be packaged on the clamping surface of the upper and lower foams. The present invention can be applied to various packages, and various packages can be packaged easily and reliably.

  In the above packaging body, when the convex portions are formed on the sandwiching surfaces of the upper and lower foams, the packaged object is derailed during transportation between the sandwiched surfaces, and the packaged object is prevented from unexpectedly jumping out between the sandwiched surfaces. The convex portion of the surface can be surely prevented, and the object to be packaged can be reliably protected from the impact applied during transportation by reliably holding the object to be packaged between the clamping surfaces.

  Further, in the above packaging body, when a plurality of convex portions are formed in a grid pattern in the vertical and horizontal directions on the sandwiching surface of the upper and lower foams, the package is placed at an arbitrary position between the sandwiching surfaces of the upper and lower foams. Even if it is sandwiched, the periphery of the packaged object can be surrounded by the convex part of the sandwiching surface of the upper and lower foams, and the convex part is securely brought into contact with the surface of the packaged object in a compressed state. The object can be more firmly held by the sandwiching surfaces of the upper and lower foams, and the packaged goods are more securely held between the sandwiching surfaces of the upper and lower foams to more reliably protect the packaged goods from the impact applied during transportation. be able to.

  Furthermore, in the packaging body, the shape-retaining sheet is disposed on the lower surface of the lower foam so as to protrude from both end edges of the upper and lower foams, and the heat shrink film faces both end edges of the upper foam. When stretched between the two edge portions of the shape-retaining sheet, and when the upper and lower foams are tightened in a direction in which the sandwiched surfaces are in close contact with each other by the heat-shrinkable film in the tensioned state The heat-shrinkable film is stretched in a tensioned state in a state of being separated from the upper and lower foams between the both end edges of the upper foam and the end edges of the shape-retaining sheet opposed thereto. The heat-shrinkable film stretched over the film smoothly absorbs the impact applied to the package during transportation, and the package has an excellent impact absorption as a whole.

  When an excessive pressing force is applied to the heat-shrinkable film, the upper and lower foams are deformed in a direction that relaxes the tension state of the heat-shrinking film according to the pressing force, and the pressing force applied to the heat-shrinking film is smoothed. Therefore, the heat-shrinkable film is not easily damaged in spite of the pressing force applied during transportation, and reliably retains the excellent shock absorption as described above.

  Further, in the above packaging body, when the upper and lower foams can be used as a cleaning tool, the upper and lower foams can be used even after the transportation of the packaging body is completed and the upper and lower foams have finished their role as cushioning materials during transportation. By using the foam as a cleaning tool for tableware, vehicles, etc., it is possible to reduce waste and contribute to the protection of the global environment.

  An example of the packaging method and package of the present invention will be described with reference to the drawings. First, the upper and lower foams 1 and 2 are prepared. As shown in FIG. 1, the upper and lower foams 1 and 2 are substantially oblong in plan and formed to have a predetermined thickness, and one surface thereof is formed on the sandwiching surfaces 11 and 21 for sandwiching an object to be packaged. Yes. The upper and lower foams 1 and 2 are manufactured in a conventionally known manner, and the planar shape is not limited to a substantially oval shape, but may be other shapes such as a circle or a rectangle as shown in FIG. Good.

  Each of the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2 is profiled. Specifically, the plurality of convex portions 11a and 21a are vertically and horizontally shaped in a grid pattern at predetermined intervals. Is formed. As a procedure for forming the convex portions 11a and 21a on the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2, while preparing a raw fabric foam sheet that is a raw fabric of the upper and lower foams 1 and 2, an infinite number of surfaces Prepare a pair of rolls with irregularities formed, supply the original fabric foam sheet between the pair of rolls and compress it, and divide the compressed original fabric foam sheet from the center in the thickness direction By cutting in this manner, it is possible to obtain a profile-processed foamed sheet in which convex portions are formed in a grid pattern at predetermined intervals in the vertical and horizontal directions on the surface. Then, the upper and lower foams shown in FIGS. 1 and 2 can be manufactured by punching the profile-processed foamed sheet into a desired shape, for example, a substantially planar oval shape.

  Then, as shown in FIG. 3, the upper and lower foams 1, 2 are overlapped with the sandwiching surfaces 11, 21 facing each other, and the article 3 to be packaged is sandwiched between the sandwiching surfaces 11, 21 of the upper and lower foams 1, 2. The laminated body A is formed in a state where the intervening material is interposed, and the shape retaining sheet 4 is disposed on the lower surface of the lower foam 1 of the laminated body A. The shape retaining sheet 4 is disposed in a state of projecting from the edges in the width direction of the upper and lower foams 1 and 2 and in a state substantially matching the edges in the length direction of the upper and lower foams 1 and 2. The package 3 is not particularly limited, and examples thereof include articles that are easily damaged by impact during transportation, such as cosmetics, jewelry, and ceramics.

  The shape-retaining sheet 4 only needs to have a rigidity that does not deform due to the shrinkage force of a heat-shrinkable film, which will be described later. Examples thereof include synthetic resin sheets, cardboard, and cardboard.

  After that, the heat shrinkable film is obtained by heat-sealing and integrating the edges of the heat shrinkable film 5 using the heat shrinkable film 5 including the shape retaining sheet 4 having the laminate A disposed on the lower surface thereof. 5 is covered entirely as a bag. The heat-shrinkable film 5 is a film that heat-shrinks when heated to a predetermined temperature or higher, and a general-purpose heat-shrinkable film is used. For example, a melted film extruded from an extruder is extruded in the direction or width. The heat-shrinkable film 5 can be produced by stretching in one or both directions and cooling the film in this stretched state.

  Next, the heat-shrinkable film 5 covering the entire surface of the laminate A is entirely heated to shrink the heat-shrinkable film 5. Then, the upper and lower foams 1 and 2 are tightened in a direction to bring the sandwiching surfaces 11 and 21 into close contact with each other by the shrinkage force of the heat-shrinkable film 5, and are arranged between the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2. The provided package 3 is firmly sandwiched between the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2 and buried between the sandwiching surfaces 11 and 21 and held in a concealed state as shown in FIGS. Such a package B is formed.

  As described above, a plurality of convex portions 11a and 21a formed from the foam are formed on the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2, and the periphery of the package 3 is a convex portion 11a (11a1), It is surrounded by 21a (21a1). Moreover, the convex portions 11a (11a1) and 21a (21a1) surrounding the article 3 are sandwiched between the upper and lower foams 1 and 2 facing the convex portions 11a (11a1) and 21a (21a1), 11 is in a compressed state in contact with 11, and the wrapping object 3 is prevented from reluctance by the compressed convex portions 11 a (11 a 1) and 21 a (21 a 1) arranged around the upper and lower foams 1. The two clamping surfaces 11 and 21 are securely clamped at desired positions so as not to be reluctant.

  Furthermore, since the plurality of convex portions 11a and 21a are formed on the entire sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2, the convex portions 11a (11a2) and 21a are also directly formed on the package 3. (21a2) is in contact in a compressed state, and the convex portions 11a (11a2) and 21a (21a2) in the compressed state formed on one foam face the package 3 toward the holding surface of the other foam. And the compressed convex portions 11a (11a2) and 21a (21a2) formed on the other foam are pressing the article 3 toward the sandwiching surface of the one foam, Therefore, the article to be packaged 3 is firmly held by the holding surfaces 11 and 21 of the upper and lower foams 1 and 2.

  Thus, in the package B, the package 3 is firmly held in a state of being sandwiched in the upper and lower foams 1 and 2 by being sandwiched between the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2. Therefore, even if an external force is applied to the package during transportation, the upper and lower foams 1 and 2 absorb the external force, and the package 3 sandwiched between the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2 has an external force. Is not transmitted, and the package 3 is not damaged.

  In addition, as described above, the packaging object 3 is simply sandwiched between the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2 when the packaging object 3 is packaged. Is not required to be formed on the sandwiching surfaces 11, 21 of the upper and lower foams 1, 2, and can be applied to the packaging of an arbitrary article 3, and the packaging body B and the packaging method of the present invention are extremely versatile. .

  The heat-shrinkable film 5 ′ formed by heat-shrinking the heat-shrinkable film 5 is in a tension state where the upper and lower foams 1 and 2 and the shape-retaining sheet 4 are tightened together. The heat-shrinkable film 5 ′ is spaced from the upper and lower foams 1 and 2 and is stretched between the both edge portions of the upper surface of the sheet and the both edge portions of the shape-retaining sheet 4 facing them.

  The heat-shrinkable film 5 ′ stretched between both edge portions on the upper surface of the upper foam 1 and both edge portions of the shape-retaining sheet 4 facing these has elasticity, and the package B during transportation Even when an external force is applied from the side, the heat-shrinkable film 5 ′ stretched between the both end edges of the upper surface of the upper foam 1 and the both end edges of the shape-retaining sheet 4 facing them is elastic. If necessary, the upper and lower foams 1 and 2 are also elastically deformed to smoothly absorb the external force applied from the side of the package B. The external force is not transmitted to the article 3 to be packaged sandwiched between the clamping surfaces 11 and 21, and the article 3 is not damaged.

  When the package B formed in this way is transported by mail, for example, a paper with a name written on the heat shrinkable film 5 ′ covering the upper surface of the upper foam 1 is pasted. You can mail it.

  And the person who received the package B by mail releases the sandwiched state of the package 3 by the upper and lower foams 1 and 2 by breaking the heat-shrinkable film 5 ′, and the sandwiching surface of the upper and lower foams 1 and 2. The package 3 can be taken out from between 11 and 21 for use.

  After the package 3 is taken out between the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2, the upper and lower foams 1 and 2 themselves finish their role as cushioning materials. 2 includes convex portions 11a and 21a formed by profile processing on the sandwiching surfaces 11 and 21, and by using an open-cell foam as the upper and lower foams 1 and 2, the upper and lower foams 1 and 2 can be It can be used as a cleaning tool for cleaning. Therefore, resources can be protected by using a foam that has been used only as a cushioning material, which has been conventionally discarded, for other purposes, and the protection of the global environment can be promoted.

  In the packaging body B, the case where the shape retaining sheet 4 is disposed on the lower surface of the lower foam 2 has been described. However, the shape retaining sheet 4 does not need to be disposed (see FIG. 6). In this case, the heat-shrinkable film 5 ′ forming the package B has the upper and lower foams 1 and 2 sandwiched between the upper and lower foams 1 and 2 in a tension state along the entire outer surfaces of the upper and lower foams 1 and 2. It is tightened in the direction of close contact. In addition, since it has the structure similar to the package B shown in FIGS. 1-5 except the shape-retaining sheet | seat 4 is not arrange | positioned, the description is abbreviate | omitted.

  In the package B, the case where the shape-retaining sheet 4 disposed on the lower surface of the lower foam 2 protrudes from the edges in the width direction of the upper and lower foams 1 and 2 has been described. As described above, the shape-retaining sheet 4 is formed in the same shape and the same size as the lower surface of the lower foam 2 or smaller than the lower surface of the lower foam 2 so that the shape retaining sheet 4 expands downward. The package B may be configured so as not to protrude from the lower surface of the body 2. In addition, since it has the structure similar to the package B shown in FIGS. 1-5 except the structure where the shape-retaining sheet 4 does not protrude from the lower surface of the lower foam 2, the description thereof is omitted.

  Furthermore, in the packaging body B, the case where the upper and lower foams 1 and 2 are entirely covered with the heat shrink film 5 ′ has been described. However, the packaging object 3 is formed by the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2. The upper and lower foams 1 and 2 need not be entirely covered with the heat-shrinkable film 5 ′. For example, the package B has the length of the upper and lower foams 1 and 2 as long as it is sandwiched. It may be configured by tightening with a ring-shaped heat-shrink film 5 ′ at the center in the direction. Since the upper and lower foam sheets 1 and 2 have the same configuration as the package B shown in FIGS. When forming such a package B, the heat-shrinkable film 5 formed in a ring shape may be used.

  Further, when the heat-shrinkable film 5 ′ of the package B is broken and the sandwiched state of the package 3 by the upper and lower foams 1 and 2 is released, the substrate placed on the sandwiching surface 21 of the lower foam 2 is removed. In order to prevent the package 3 from popping out unexpectedly, as shown in FIG. 8, after placing the package 3 on the sandwiching surface 21 of the lower foam 1, The package 3 may be integrated using a cylindrical band body 6. In addition, about the structure similar to the up-and-down foams 1 and 2 shown in FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the package B, the case where the convex portions 11a and 21a are formed on the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2 has been described. However, as shown in FIG. The convex portions 11a and 21a are not formed on the sandwiching surfaces 11 and 21, and the sandwiching surfaces 11 and 21 of the upper and lower foams 1 and 2 may be formed on flat surfaces. In addition, about the structure similar to the up-and-down foams 1 and 2 shown in FIG. 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
