Description

The present invention relates to an air packing member that packs a product in order to protect the product from impacts and vibrations, and is an air packing member that can be filled with air during packing, and an air packing member in which the air packing member is installed. The present invention relates to a packing box with packing and an air packing system for packing an object to be packed using the packing box with air packing.

  In a distribution channel such as product transportation, an air packing member filled with a gas such as air may be used to pack consumer goods and industrial products. In particular, since the air packing member that can be filled with gas at the time of use is composed of a thin sheet made of a resin film, it is characterized in that it can be stored compactly when no gas is introduced. In addition, since it has a simple configuration, it does not require a mold for manufacturing, does not generate debris or dust like foamed polystyrene, can use recyclable materials for resin film, and can be manufactured and transported at low cost There is.

  16 and 17 show an example of a conventional air packing member. The air packing member 100 is formed by thermally welding an upper film 100a and a lower film 100b made of a thermoplastic resin. In general, each thermoplastic film is composed of a single or multi-layer material such as polyethylene, nylon, polyethylene, bonded together by a suitable adhesive or other method. The upper film 100a and the lower film 100b are thermally welded to each other at the heat welding portion 107.

  An air guide member 101 and a plurality of air tube portions 102 arranged in parallel are formed on the air packing member 100 by heat welding. A check valve 103 allows air to flow between the air guide portion 101 and the air tube portion 102. Here, due to the function of the check valve 103, air is easy to flow from the air guide portion 101 to the air tube portion 102, and extremely difficult to flow from the air tube portion 102 to the air guide portion 101.

  Each air tube portion 102 includes a check valve portion 104 including a check valve 103 and a plurality of air bubble portions 105 communicated through an air passage 106. When the air packing member 100 is used, air is injected from the air injection port 101a with a predetermined air pressure. Then, the injected air passes through the check valve 103 from the air guide portion 101 along the arrow in FIG. 16 and is introduced into each air tube portion 102. In each air tube portion 102, air is sequentially introduced into the air bubble portion 105 via the air passage 106. As described above, since the check valve 103 restricts the air flow from the air tube portion 102 side to the air guide portion 101 side, the air bubble portion 105 and the check valve portion 104 are filled with air. Swells as shown.

  The air bubble part 105 and the check valve part 104 serve as a cushioning material, and the damage and vibration of the product packed by the air packing member 100 can be suppressed. The main purpose of forming the plurality of air tube portions 102 independently is to increase the reliability of the air packing member 100. That is, even if air leakage occurs in one air tube portion 102 for some reason, the other air tube portions 102 are still filled with air, and the cushioning property can be maintained. Thus, the air packing member 100 can continue to function as a cushion or cushioning material that protects the product.

  The check valve 103 is composed of two thermoplastic valve films joined together to form an air flow path. The check valve 103 has a valve opening 103a at the tip and a valve main body 103b, and air is introduced from the air guide portion 101 into the check valve 103 through the valve opening 103a at the tip. The introduced air is prevented from flowing back by the valve body 103b. The check valve 103 is formed by thermally welding the upper film 100a or the lower film 100b of the air packing member 100 and another film during or after the manufacturing process of the air packing member 100.

  Next, an example of a packing method in which the above air packing member is applied and combined with a packing box will be described. FIG. 18 shows an example of the air packing member in this case. In this figure, the heat-welded portion of the two films is indicated by a solid line for simplicity as well as hatching. In this example, the developed view of the air packing member has a substantially cross shape. The air packing member 110 includes a bottom surface portion 110a, a left side surface portion 110b, a right side surface portion 110c, an upper side surface and an upper ceiling portion 110d, and a lower side surface and a lower ceiling portion 110e, which are cross-shaped central portions.

  Further, in this example, the air guide portion 111 is provided so as to penetrate the central portion of the air tube portion 112 constituting the upper side surface and the upper ceiling portion 110d, the bottom surface portion 110a, the lower side surface and the lower ceiling portion 110e. When air is injected from an air inlet 111a provided at a position on the lower side surface and the end of the lower ceiling portion 110e in the air guide portion 111, the air that has passed through the air guide portion 111 is air tube. It is introduced to the right side of the portion 112, spreads over the entire air tube portion 112, and expands the entire air packing member 110.

  FIG. 19 shows a packing method when packing a product as an object to be packed with such an air packing member 110 and a packing box 120. The bottom surface portion 110a of the air packing member 110 in a state before injecting air is installed so as to match the bottom surface 120a of the packaging box 120. In this state, the product is stored from above the air packing member 110, the upper side of the product is covered with the ceiling portion of the air packing member 110, and the lid of the packing box 120 is closed. Then, by injecting air from the air inlet 111a, the air packing member 110 is expanded inside the packing box 120 to fill the space between the product and the packing box 120 with a predetermined pressure, and the product is fixed and buffered. It is possible. In this case, since the air packing member 110 has a substantially cross shape, it is necessary to remove the portion surrounded by the alternate long and short dash line in FIG. 18 in the state of the sheet material, which disadvantageously increases the waste of the sheet material. is there.

  FIG. 20 shows another example of the air packing member on the premise that it is installed in the packing box. In this example, waste of sheet material such as a portion surrounded by a one-dot chain line in FIG. 18 is eliminated. In FIG. 20, a thick solid line indicates a cut provided in the air packing member 130. The air packing member 130 is provided with a bottom surface portion 130a, a left side surface portion 130b, a right side surface portion 130c, an upper side surface portion 130d, a ceiling portion 130j, and a lower side surface portion 130g. In addition, both the upper side left part 130e on both sides of the upper side part 130d, the upper side right part 130f, the lower side left part 130h on both sides of the lower side part 130g, the lower side right part 130i, and both sides of the ceiling part 130j. A left ceiling portion 130k and a right ceiling portion 130l are provided.

  However, when the air packing member 130 is to be installed in the packaging box, the left side surface portion 130b, the upper side surface left portion 130e, and the lower side surface left portion of the air packing member 130 are arranged on one of the four side surfaces of the packaging box. 130h and the ceiling left part 130k will overlap four times. Further, on the opposite side surfaces, the right side surface portion 130c, the upper side surface right portion 130f, the lower side surface right portion 130i, and the ceiling right portion 130l overlap four times. As a result, the balance of the function of the air packing member 130 as a cushioning material is greatly lost.

  That is, when air is injected from the air inlet 131a, which is the lower end of the air guide portion 131, air is introduced into the air tube portion 132 and the entire air packing member 130 expands. However, the air packing member 130 overlaps four times. On the other side, the thickness becomes abnormally thick.

  Hereinafter, embodiments of an air packing member, a packing box with air packing, and an air packing system according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a basic configuration of an air packing sheet 10 as an air packing member in the present invention. FIG. 1 is a development view before the air packing sheet 10 is filled with air. The air packing sheet 10 is formed by laminating an upper thermoplastic film as a first thermoplastic film made of a thermoplastic resin and a lower thermoplastic film as a second thermoplastic film by thermal welding. And the air guide part 1 extended in the strip shape in the horizontal direction in the figure is formed, and the air tube part 2 arranged in parallel in the longitudinal direction of the air guide part 1 in the longitudinal direction on the side surface of the air guide part 1 is formed. Is formed. The air tube portion 2 is formed to extend in a strip shape in a direction perpendicular to the longitudinal direction of the air guide portion 1.

  A connecting portion between the air guide portion 1 and the air tube portion 2 is coated with a release agent 3 to form an opening portion that is not thermally welded between the air guide portion 1 and the air tube portion 2. And the air tube portion 2 are allowed to circulate air. The release agent 3 is, for example, a kind of paint having high heat resistance. Even if heat is applied to bond the upper thermoplastic film and the lower thermoplastic film, the release agent 3 is not applied at the position where the release agent 3 is applied. The thermoplastic film and the lower thermoplastic film are not bonded together.

  A check valve portion 4 is formed on the air tube portion 2 side of the release agent 3. The check valve portion 4 is formed by a heat welding pattern that allows air to easily flow from the air guide portion 1 to the air tube portion 2 and makes air extremely difficult to flow from the air tube portion 2 to the air guide portion 1. The air injected from the air inlet 1a into the air guide part 1 flows into the air tube part 2 and expands the air tube part 2, while the air in the air tube part 2 leaks to the air guide part 1 side. It is designed not to go. Moreover, each air tube part 2 is divided | segmented so that the distribution | circulation of air can be carried out in the longitudinal direction by heat welding, and the several air bubble part 5 is formed.

As shown in FIG. 1, the air packing member 10 in the present embodiment is a first air tube group 6 composed of three relatively long air tube portions 2a and a first air tube portion 2b composed of four relatively short air tube portions 2b. 2 air tube group 7. And the three air tube parts 2a in the 1st air tube group 6 are partially heat-welded in each three places, and are divided into an air bubble part, The 1st side part 6a, the 1st bottom face part 6b, Two side surfaces 6c and a ceiling 6d are formed.

  In addition, the four air tube portions 2b in the second air tube group 7 are divided by being thermally welded at two locations, respectively, so that the third side surface portion 7a, the second bottom surface portion 7b, and the fourth side surface portion 7c are formed. Is formed.

  Further, the boundary air tube portion 2c formed at the boundary portion between the first air tube group 6 and the second air tube group 7 is blocked by the air valve portion 4 by thermal welding, and air does not leak from the air valve portion 4. In addition, as shown by a thick solid line in the figure, the central portion is cut in the longitudinal direction. Thereby, the 1st air tube group 6 and the 2nd air tube group 7 are moved independently, and it becomes possible to implement | achieve various attitude | positions with the air packing sheet 10. FIG.

  In FIG. 2, the bending method at the time of using the air packing sheet | seat 10 in a present Example is shown. First, in the present embodiment, the air guide portion 1 is bent substantially vertically at the connecting portion 1b with the boundary air tube portion 2c. And between the 1st side surface part 6a, the 1st bottom face part 6b, the 2nd side surface part 6c, and the ceiling part 6d of the 1st air tube group 6, it bends at substantially right angle, respectively. Further, the third side surface portion 7a, the second bottom surface portion 7b, and the fourth side surface portion 7c in the second air tube group 7 are bent at substantially right angles (in this case, the air packing sheet 10 itself is flexible so It is not possible to maintain the shape with the product.In fact, the shape can be maintained only after the packaged product is stored.) Then, the first air tube group 6 and the second air tube are arranged such that the second bottom surface portion 7b of the second air tube group 7 comes to the lower side (outside) of the first bottom surface portion 6b of the first air tube group 6 in the figure. Combine with group 7. At that time, the first air tube group 6 and the second air tube group 7 are made to intersect at a substantially right angle.

  At this time, in the present embodiment, the first bottom surface portion 6b is provided with a first center mark 6e, and the second bottom surface portion 7b is provided with a second center mark 7d. And when combining the 1st air tube group 6 and the 2nd air tube group 7, the 1st bottom face part 6b and the 2nd bottom face part 7b are piled up by overlapping the 1st center mark 6b and the 2nd center mark 7d. Are designed to overlap properly. As a result, the first bottom surface portion 6b and the second bottom surface portion 7b can be easily overlapped with the center portion in proximity.

  FIG. 3A shows a perspective view in a state where the folding of the air packing sheet 10 is completed. When the folding of the present embodiment is completed, a substantially rectangular parallelepiped can be formed with the air packing sheet 10, and a product that is an object to be packed can be surrounded by the rectangular parallelepiped shape. Further, in the present embodiment, only the bottom surface portion on which the weight of the product acts can be double-covered with the first air tube group 6 and the second air tube group 7, thereby protecting the product more reliably. It becomes possible.

In this embodiment, as shown in FIG. 3 (b), the folded air-packing member 10 is installed in the packing box 12, and at that time, the packing box 12 is used for air injection. It is good to provide the window part 12a. Then, the air packing sheet 10 is first folded and spread on the packing box 12, the product is stored, the ceiling portion 6d is covered on the product, the lid of the packing box 12 is closed, and then exposed from the window portion 12a. Air is injected from the air inlet 1a. Then, the air packing sheet 10 can be expanded more easily after the product is boxed, and the air packing sheet 10 can more reliably fill the space between the product and the inner wall of the packing box 12. Thereby, it becomes possible to protect the product in the packing box 12 more reliably.

  At this time, as shown in FIG. 3 (b), when the double-sided tape 1 c is affixed to the portion of the air guide portion 1 that is in contact with the inner surface of the packaging box 12 and the air packing sheet 10 is installed in the packaging box 12. First, the air guide portion 1 may be fixed to the inner wall of the packaging box 12 with the double-sided tape 1c so that the air inlet 1a is exposed from the window portion 12a. If it does so, the air packing sheet | seat 10 can be appropriately fixed to the packaging box 12 so that the air inlet 1a may be exposed from the window part 12a, and workability | operativity at the time of packaging of a product can be improved. . At that time, the double-sided tape 1c is preferably attached to a portion as close to the window portion 12a as possible. If it does so, the air injection | pouring operation | work from the air inlet 1a can be stabilized more.

  At that time, a center mark (not shown) that should overlap the first center mark 6b and the second center mark 7d of the air packing sheet 10 may be provided at the center of the bottom surface of the packing box 12. If it does so, when installing the folded air packing sheet 10 in the packaging box 12, it becomes possible to form the rectangular parallelepiped by the air packing sheet 10 in the state matched with the shape of the packaging box 12 more correctly.

  As described above, in this embodiment, when the package is enclosed in a rectangular parallelepiped shape, the development view of the air packing member 10 shows that the two air tube groups 6 and 7 are arranged in parallel and the end portion is an air guide. Since it becomes the structure connected to the part 1, it is possible to reduce the waste of a sheet material compared with the case where a developed view becomes a cross shape. Further, since the bottom surface portions 6b and 7b of each air tube group can be placed on the bottom surface of the rectangular parallelepiped shape, the buffering function on the bottom surface of the rectangular parallelepiped shape on which the weight of the product acts directly can be intensively improved. .

  In the present embodiment, the three air tube portions 2a in the first air tube group 6 are the boundary portion between the first side surface portion 6a and the first bottom surface portion 6b, and the first bottom surface portion 6b and the second side surface portion. It is partially heat welded at the boundary between 6c and the boundary between the second side surface 6c and the ceiling 6d. Further, the four air tube portions 2b in the second air tube group 7 are the boundary portion between the third side surface portion 7a and the second bottom surface portion 7b, and the boundary portion between the second bottom surface portion 7b and the fourth side surface portion 7c. Since it is partially thermally welded, it is possible to accurately bend and form each surface of the first air tube group 6 and the second air tube group 7, and to form a rectangular parallelepiped shape more easily and stably. It is possible to configure.

  In addition, the number and width of the air tubes 2 constituting the air tube group in the present invention, the position where the air tube portion 2 is partially thermally welded, and the like are not limited to those described in the above embodiments. Of course, it may be appropriately changed according to the size and weight of the product to be packed, the size of the packing box, and the like.

  In the above embodiment, the air packing sheet has two air tube groups and a rectangular parallelepiped is formed by the two air tube groups. However, the scope of application of the present invention is not limited to this. For example, the air packing sheet may have three air tube groups, and the three air tube groups may form a polyhedral shape such as a hexagonal plan view. Similarly, it is natural that the plan view may be an octagon.

  In addition, it is possible to appropriately change which of the two air tube groups is to form the bottom surface outside or which of the ceiling portions is formed.

Next, a second embodiment of the present invention will be described. In Example 1, in the three air tube parts 2a which comprise the 1st air tube group 6, the part between the 1st side part 6a and the 1st bottom face part 6b, the 1st bottom face part 6b, and the 2nd side part 6c The part between the second side part 6c and the ceiling part 6d is partially heat-welded to facilitate folding. Moreover, in the air tube part 2b which comprises the 2nd air tube group 7, the part between the 3rd side part 7a and the 2nd bottom face part 7b, between the 2nd bottom face part 7b and the 4th side face part 7c The part was partially heat welded to facilitate folding. However, even when a rectangular parallelepiped is formed by the air packing sheet to surround the product, the location of the heat welding of the air tube portion 2 is not limited to the above.

  For example, the air tube part in the ceiling part may be finely divided by heat welding at more places in the longitudinal direction, thereby forming more air bubble parts in the ceiling part. FIG. 4 shows a development view of the air packing sheet 20 in that case. In FIG. 4, only parts different from those in FIG. 1 are shown with reference numerals, and description of components equivalent to those in FIG. 1 is omitted. In this example, the air tube portion 12a constituting the ceiling portion 16d is thermally welded at three locations within the ceiling portion 16d to form four air bubble portions 15 respectively.

  By doing so, as shown in the cross-sectional view of FIG. 5, the ceiling portion 16d has higher flexibility, and the air packing sheet 20 can be more reliably secured even when the shape of the product to be stored is complicated. Can be fitted to the product. As a result, as shown in FIG. 6, when the air packing sheet 20 is installed in the packing box 22 and the product is stored and then filled with air, the product can be more reliably protected.

  Next, a third embodiment of the present invention will be described. In the present embodiment, a description will be given of a case where, in the ceiling portion formed by the first air tube group, the heat welding portion for forming the air tube portion and the air valve portion is removed, and one air bubble is formed in the entire ceiling portion. To do.

  FIG. 7 shows a development view of the air packing sheet 30 in the present embodiment. In the present embodiment, the three air tube portions 22a of the first air tube group 6 are not formed on the ceiling portion 26d. Further, there is no air bubble portion formed by dividing the air tube portion 22a in the longitudinal direction by heat welding. One air bubble part 25 is formed in the whole ceiling part 26d.

  According to this, as shown in the cross-sectional view of FIG. 8, it is possible to particularly increase the thickness of the air bubble portion 25 of the ceiling portion 26d, and to fit the ceiling portion 26d to the shape of the product, The product can be pressed and fixed from above with sufficient pressure.

  According to this, for example, when the product is packed in the air packing sheet 30 and the packing box and transported to a domestic transport destination, especially in applications where the package is not opened during transport, the product is fixed and cushioned. Reliability can be improved. In addition, when it is expected to be opened at customs clearance, such as when transporting to overseas destinations, an appropriate number is also provided on the ceiling portion 26d so that the opening and packing operations are easier. It may be adjusted so that the air tube portion 22a and the air bubble portion 25 are formed.

  Next, a fourth embodiment of the present invention will be described. In the present embodiment, in the bottom surface portion formed by the first air tube group and the second air tube group, by reducing the volume of the air valve portion, it was suppressed that only the thickness of the bottom surface portion was excessively increased. The case will be described.

In FIG. 9, the air packing sheet | seat 40 in a present Example is shown. The first bottom surface portion 36b of the air packing sheet 40 has four air bubble portions 3 per one air tube portion.
5 is formed, and a total of 12 air bubble portions 35 are formed. On the other hand, on the second bottom surface portion 37b, five air bubble portions 35 are formed for each air tube portion, and a total of 20 air bubble portions 35 are formed.

  According to this, since each volume of the air bubble part 35 which forms the 1st bottom face part 36b and the 2nd bottom face part 37b can be suppressed, each thickness at the time of injecting air can be suppressed. It becomes possible. Therefore, when the air packing sheet 40 is bent and the first bottom surface portion 36b and the second bottom surface portion 37b are overlapped to form a rectangular parallelepiped shape, it is possible to suppress only the thickness of the bottom surface portion from being excessively increased.

  Moreover, the 2nd aspect of the air packing sheet | seat in a present Example is shown in FIG. In the air packing sheet 50 shown in FIG. 10, in the first bottom surface portion 46b and the second bottom surface portion 47b, the width of the air tube portion is ½ of the other portions, and the volume of the air bubble portion 45 is reduced. We are going to suppress it. This also makes it possible to suppress the thickness of each air bubble portion 45 when air is injected. Therefore, when the air packing sheet 50 is bent and the first bottom surface portion 46b and the second bottom surface portion 47b are overlapped to form a rectangular parallelepiped shape, it is possible to suppress only the thickness of the bottom surface portion from being excessively increased.

  Moreover, the 3rd aspect of the air packing sheet | seat in a present Example is shown in FIG. In this aspect, the number of air tube portions forming the first bottom surface portion 6b is the same as that of the first side surface portion 6a, the second side surface portion 6c, and the ceiling portion 6d, while forming the second bottom surface portion 53b. The number of air tube portions 52 to be performed is five times the normal number, and the second bottom surface portion 53b is formed by a total of 20 air tube portions 52.

  According to this, as shown in the cross-sectional view of FIG. 12, the thickness of the second bottom surface portion 53b can be reduced, and the air packing sheet 55 is bent to overlap the first bottom surface portion 6b and the second bottom surface portion 53b. When the rectangular parallelepiped shape is formed together, it can be suppressed that only the thickness of the bottom surface portion becomes excessively thick.

  Thus, according to the present embodiment, the bottom surface when the rectangular parallelepiped shape is formed with the air packing sheet by appropriately adjusting the number of air tube portions and air bubble portions forming the first bottom surface portion and the second bottom surface portion. It is possible to adjust the thickness. Of course, the number of air tube portions and air bubble portions forming the first bottom surface portion and the second bottom surface portion is not limited to that shown in the present embodiment.

  Next, a fifth embodiment of the present invention will be described. In the present embodiment, an example will be described in which the end of the first air tube group and the second air tube group opposite to the air guide portion can be repeatedly opened and closed.

  In FIG. 13, the expanded view of the air packing sheet | seat 60 in a present Example is shown.

The upper double fastener portion 58a has a substantially circular cross section at the tip, and two fastener convex portions 580a formed over the entire width of the first air tube portion 56, and the lower double fastener portion 58b has a fastener convex portion 580a. The front end of the substantially circular cross section is inserted, and a fastener recess 580b that locks using the elasticity of the resin is formed in two steps over the entire width of the first air tube portion 56.

  Then, by pressing the upper double fastener portion 58a and the lower double fastener portion 58b together, the fastener convex portion 580a and the fastener concave portion 580b are coupled to each other, so that the end portions of the air tube portions of the first air tube group 56 are joined. Can be sealed. Further, by releasing the upper double fastener portion 58a and the lower double fastener portion 58b in the direction away from each other, the coupling between the fastener convex portion 580a and the fastener concave portion 580b is released, whereby each air in the first air tube group 56 is released. It becomes possible to open the end of the tube portion.

  Since the detailed configuration of the double fastener portion 59 in the second air tube group 57 is the same as that of the double fastener portion 58, description thereof is omitted here. In the present embodiment, in order to seal or open the double fastener portion 58, the upper double fastener portion 58a and the lower double fastener portion 58b may be pressed or peeled by hand, or a predetermined slider (not shown) ) And by sliding the slider in the width direction of the first air tube group 56, the upper double fastener portion 58a and the lower double fastener portion 58b may be pressed or peeled off. Further, the detailed configuration of the double fastener portion 58 is not limited to the present embodiment, and other configurations may be adopted as long as the end portion of the first air tube group 56 can be repeatedly opened and closed. Good. Of course, you may make it provide the single fastener part in which the fastener convex part and the fastener recessed part were each provided in one step.

  As described above, according to the present embodiment, since the first air tube portion 56 and the second air tube portion 57 are configured to be able to repeatedly open and close the opposite ends of the air guide portion 1, the air packing The sheet 60 can be used for the passing box, and can be used repeatedly. Moreover, since the air packing sheet 60 can be used a plurality of times, the total cost can be reduced.

  In the present embodiment, when the air packing sheet 60 is folded to form a rectangular parallelepiped shape, the double fastener portions 58 and 59 are both located above the rectangular parallelepiped shape. Therefore, the opening and closing operation of the double fastener portions 58 and 59 when the air packing sheet 60 is used for the passing box is facilitated, and the efficiency of the packing operation can be improved.
