Description

  The present invention relates to a transport container used when transporting a transported object, and more particularly to a transport container that can be used repeatedly. Specifically, the inner bag and the outer bag constitute a transport container, and the inner bag is configured as a storage bag having a buffer sheet therein and capable of being sucked in vacuum, and the outer bag has a buffering effect by air injection. By comprising the air cushion portion, the buffering effect is enhanced, and even when a plurality of irregularly shaped conveyed items are stored simultaneously, these irregularly shaped conveyed items can be conveyed without being damaged.

  A transport container suitable for transporting various transported goods from daily miscellaneous goods to various products produced in a factory, and a transport container that can be used repeatedly has been developed (for example, Patent Document 1).

  The transport container disclosed in Patent Document 1 is a bag containing a buffer bag inside the bag so as to be convenient when transporting a standard transport object such as a flat and small product produced in a factory. is there. By injecting air into the buffer bag, the stored transported object can be protected from external impact.

Japanese Utility Model Publication No. 51-58775

  By the way, the technique disclosed in Patent Document 1 is to provide a buffer bag so that a transported object stored inside can be safely transported. An eggplant is preferred. For example, for flat products, multiple products are stacked to fit the internal volume, and if air is injected in that state, the products will be packed in close contact with each other. They can be transported safely to their intended purpose without colliding with each other.

  However, if you try to pack and transport items with different shapes and sizes in the storage part, gaps will be created between the items to be transported, so if a large impact is applied to the transport container, the items will collide with each other. May be damaged. Therefore, even if the conveyed product is an indeterminate type, it is necessary to have a structure that is not easily damaged.

  Therefore, the present invention solves such a conventional problem, and proposes a transport container that can transport these transported articles without damaging them even when a large number of irregularly transported articles are stored. .

In order to solve the above-described problem, the transport container according to the present invention described in claim 1 is composed of an inner bag and an outer bag for storing the inner bag,
The inner bag has a storage portion for storing a transported object provided with a buffer sheet therein, and
It is configured as a storage bag having an air suction port that sucks the air in the storage portion to make it in a substantially vacuum state,
The outer bag is composed of a cushioning air cushion part and an air injection part for injecting air into the air cushion part.

  In this invention, a conveyance container is comprised by the inner bag which has an accommodating part, and the outer bag which accommodates this inner bag. A buffer sheet is laid (attached) inside the inner bag. As the buffer sheet, a flexible buffer sheet having a large number of hemispherical air bags is used.

  A storage bag that can be vacuum-packed (vacuum packed) is used as the inner bag. For this reason, the inner bag has an opening for taking in and out the conveyed product, and the opening is provided with an opening / closing means. The opening / closing means can be composed of a slide-type fastener that can slide left and right and a slider that opens and closes the fastener. When the fastener is closed, the storage is sealed.

  The inner bag is provided with an air suction port for bringing the inner bag into a substantially vacuum state. When the inner bag is evacuated, the conveyed items housed inside are in close contact with each other, and the buffer sheet is in close contact with the outer shape of the conveyed item.

  Thus, even if an impact is applied from the outside due to the buffering effect and the vacuum effect by the buffer sheet, there is no possibility that the conveyed product is damaged by the impact force.

  On the other hand, the outer bag is configured as an air cushion portion that provides a buffering effect with respect to the inner bag. The air cushion portion is composed of air cushions provided on the left and right surfaces, the bottom surface, and preferably the front and rear surfaces of the outer bag. Each air cushion is appropriately sized and shaped according to the place of use. For example, the air cushion may be formed into a rod shape, and a large number of the air cushions may be used, and the plurality of air cushions may be arranged in a column.

  By using a rod-shaped (columnar) air cushion, the air cushion protrudes like a kamaboko. Due to the presence of the uneven portions, the length of the impact distance with the inner bag can be made as long as possible. The impact force can be weakened.

  A rod-shaped air cushion can also be used for the bottom portion, but a mat-shaped air cushion can also be used in some cases. When the mat-shaped air cushion is used, the stability of the conveyed product before the inner bag is brought into a substantially vacuum state is increased.

  The conveyed product can be taken out of the inner bag and stored, or can be stored with the inner bag attached to the outer bag. In any case, when a plurality of irregularly conveyed objects are stored in the inner bag, the opening is closed by the slider, and the air inside the inner bag is sucked (exhausted) in that state. Since the inner bag is a highly airtight storage bag, both the inner bag and the buffer sheet attached to the inner bag gradually begin to deform due to the suction of air, and are almost in close contact with the outer surface of the stored items. To do.

  The outer shape of the transported object is indefinite, and the stacked upper and lower transported objects are not necessarily the same shape, but the buffer sheets gradually adhere to the outer surface following the outer shape of the transported object. In addition to being in close contact with each other, if there is unevenness between adjacent transported objects, the buffer sheet closely contacts the unevenness. As a result, a plurality of conveyed items can be regarded as being integrated through the buffer sheet.

  After the inner bag is in a substantially vacuum state, air is injected into the air cushion portion of the outer bag. When air is injected, the inner bag is pressed by the air cushion provided in each part, and thus the inner bag is completely fixed by these air cushions. By the cooperation of the air cushion and the buffer sheet of the inner bag, the conveyed product in the inner bag is almost certainly protected from an external impact. Therefore, even if some external impact is applied to the outer bag due to dropping during conveyance or collision with other objects, there is no possibility that the conveyed object is damaged. Of course, even if an external impact is applied, the inner inner bag does not protrude from the opening of the outer bag.

  When unpacking the transported item, first remove the air from the outer bag. The air in the air cushion part can be exhausted by opening the check valve in the air injection part. Since the inner bag is freed by removing the air, the opening portion of the inner bag is opened using the slider while it is stored in the outer bag or is taken out from the outer bag. Thus, since air enters the inner bag, the conveyed items become free. Thereafter, the conveyed product in the inner bag is taken out.

  Since the inner bag and the outer bag can be reused as long as they are not damaged, a reusable transport container can be provided.

  In this invention, the inner bag and the outer bag constitute a transport container, and the inner bag is configured as a storage bag having a buffer sheet therein, which can be vacuum-sucked, and the outer bag has a buffering effect by air injection. The air cushion part is configured.

  According to this, even if a plurality of transported objects are mixed and stored at the same time regardless of the fixed form or the indeterminate form, the transported objects can be transported without being damaged. The double cushioning effect of the inner bag and outer bag ensures the safety of the conveyed product.

  Subsequently, a preferred embodiment of the transport container according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a main part showing an example of a transport container, in particular, a transport container 1 with an inner bag, showing the outline of the present invention. This conveyance container 1 is comprised by the inner bag 10 which accommodates a conveyed product, and the outer bag 100 conveyed in the state which accommodated this inner bag 10. FIG.

  If the inner bag 10 has a rectangular parallelepiped shape, the outer bag 100 is also configured as a storage bag that is slightly larger than the inner bag 10. Both the inner bag 10 and the outer bag 100 are provided with a buffer function.

  For convenience of explanation, explanation starts from the inner bag 10. The inner bag 10 is provided in a box shape having a predetermined size as shown in FIG. 1, and has a storage portion 12 for storing a conveyed product as shown in FIG. As shown in FIG. 2, the inner bag 10 has a soft sheet 22 as a base, a buffer sheet 14 is adhered to the inner surface (the storage portion 12 side), and an opening / closing means 20 is provided at the distal end portion side of the opening portion 16. Is provided. In this example, an air suction port 50 having a check valve function is provided in the overhanging portion 42 (see FIG. 3) facing the opening 16.

  The soft sheet 22 is molded using a polyethylene sheet or a polyurethane sheet having airtightness as a raw material, and FIG. 3 is a development view thereof. In this example, as shown in FIG. 3, left and right side surface portions 26A and 26B and front and rear surface portions 28A and 28B are provided continuously to the bottom surface portion 24, and are further connected to the left and right side surface portions 26A and 26B on the outer sides thereof, respectively. , 30B are provided.

  The front and rear surface portions 28A and 28B are provided with overhang portions 42A and 42B that constitute a part of the opening. Each surface portion is provided with a welded portion 40, and the contact end surfaces of the corresponding soft sheet 22 are thermally welded to form a box-shaped inner bag 10.

  Opening / closing means 20 for sealing and opening the opening 16 is provided at the end portions 32A and 32B of the opening surface portions 30A and 30B. In this example, the opening / closing means 20 includes a belt-like fastener 21 and a slider 20C. The fastener 21 is a slide type, and is composed of a ridge 21A provided on one end portion 32A side and a ridge 21B provided on the other end portion 32B side. When the slider 20C is slid, the protrusions 21A are fitted into the recesses 21B, so that the opening 16 is closed and the opening 16 can be sealed. Moreover, the opening part 16 can be opened by separating both 21A and 21B.

  When the slider 20C is slid to the left side (or right side) of the outer surface of the soft sheet 22 with respect to the fastener 21, the slider 20C is slid to a position not related to the fastener 21 (welding position in FIG. 3). 16 can be sealed. When opening the opening 16, the other tip 32B may be manually pulled away from one tip 32A.

  The inside of the inner bag 10 functions as a storage unit 12 for a conveyed product. In order to protect this conveyed product, a buffer sheet 14 is adhered to the inner surface of the inner bag 10. If an adhesive may be used, the adhesive may be adhered and fixed to the inner surface of the soft sheet 22 by partial heat welding.

  As shown in FIG. 4, the cushion sheet 14 is a sheet having a soft base sheet 36 such as polyethylene or polyurethane, and a large number of hemispherical small air bags 38 formed on one surface thereof. By providing a large number of air bags 38, a predetermined gap 39 is formed between the air bags 38. Then, as shown in FIG. 2, the buffer sheet 14 is attached to each inner wall surface of the soft sheet 22 so that the air bag 38 faces the inner surface of the inner bag 10. The large number of air bags 38 hold the outer surface of the conveyed product and absorb external impacts.

  As shown in FIGS. 1 and 3, in this example, an air suction port 50 is provided in the overhanging portion 42A. It is assumed that the length of the air suction port 50 is selected so that the air suction port 50 can be sucked from the outside of the outer bag 100 described later. Of course, the air suction port 50 having a length unrelated to the outer bag 100 may be used.

  The air suction port 50 is provided with an exhaust valve (a deaeration valve) used when the inside of the inner bag 10 is brought into a substantially vacuum state. That is, an exhaust valve having a structure in which the valve is opened when the air inside the inner bag 10 is sucked and the valve is closed when the air suction is finished is built in the air suction port 50. The easiest way to exhaust air is to use a vacuum cleaner. In the case of a cleaner, a connection hose (not shown) that connects the air suction port 50 and the tip of the hose of the cleaner is used.

  Alternatively, a valve (not shown) attached to a commercially available futon compression bag or the like can be used as it is as the air suction port 50. In that case, this valve is attached to an appropriate position of the inner bag 10 (for example, a position not blocked by the buffer sheet 14 at the upper part of the left side surface portion). When this type of valve is used as the air suction port 50, as will be described later, the inner bag 10 is taken out of the outer bag 100 and air is sucked. Other modifications of the air suction port 50 will be described later.

  FIG. 5 shows an example in which the conveyed product is stored using the inner bag 10 configured as described above. The shape and size of the conveyed product to be conveyed are not limited. That is, there is no restriction on the shape of an object to be transported, regardless of whether it is a fixed type or an indefinite type. It can also be packed and transported in a state where both standard and indeterminate items are mixed. FIG. 5 shows a mixed example, and the transported object 60 is illustrated in a rectangular parallelepiped shape, a spherical shape, and a pyramid shape.

  FIG. 5 shows a state in which a plurality of indeterminate transport objects 60 are stored in the storage portion 12 of the inner bag 10. When the opening 16 is sealed using the opening / closing means 20 in this state and air is sucked through the air suction port 50 in this state, the airtight inner bag 10 is also attached to the inner bag 10. The buffer sheet 14 thus formed gradually begins to deform and adheres in a state along the outer surface of each of the stored transported objects 60.

  Since the buffer sheet 14 gradually adheres to the outer surface following the outer shape of the conveyed product 60, the plural conveyed items 60 also adhere to each other. If there are irregularities between adjacent conveyed items, the buffer sheet 14 follows the irregularities. The buffer sheet 14 is in close contact. As a result, a plurality of conveyed items can be regarded as being integrated through the buffer sheet 14 as shown in FIG.

  As described above, in the process in which air is sucked and the buffer sheet 14 is in close contact with the outer surface of the transported object 60, the hemispherical air bag is placed on the side of the buffer sheet 14 in contact with the transported object 60. Since a plurality of 38 are provided, the air flow accompanying the air suction is suitably performed by the gaps between the hemispherical air bags, and the air can be satisfactorily sucked.

  When the relationship between the conveyed product 60 and the buffer sheet 14 is observed in more detail, if there is a void 62 where the conveyed items 60 are not in contact with each other as shown in FIG. 7, the buffer sheet 14 enters the portion of the void 62. The air bag 38 at that location is in close contact with the outer surface of the conveyed product 60. As a result, the conveyed items 60 come into close contact with each other by the buffer sheet 14, and even the irregularly conveyed items 60 are fixed to each other. As a result, it can be regarded as a combination of a plurality of transported objects 60.

  Next, the outer bag 100 shown in FIG. 1 will be described. In this example, as shown in FIG. 1, one strip-shaped soft sheet is used as the base sheet 102. As the material, a sheet (film) that is highly flexible and difficult to break, such as a polyethylene sheet or a polyurethane sheet, is used as described above.

  In order to form the base sheet 102 into a substantially box shape, both end faces 102a and 102b are welded as shown in FIG. By making it into a box shape, it becomes a hexahedron, but in this example its top surface is open, so it becomes a pentahedron. The base sheet surface and the bottom surface portion excluding the three ridge line portions (corner portions) 104a to 104c are configured as air cushion portions 110 to 118, respectively.

  In this example, air cushion portions 110 to 118 are provided on each of the left and right side surface portions 106A and 106C, the front and rear surface portions 106B and 106D, and the bottom surface portion 106E. Among these, there are a plurality of air cushion portions 110 to 116. In the example, it is configured by four air cushions, and the narrow bottom surface portion 106E is an example in which the air cushion portion 118 is configured by two air cushions 118A and 118B. The air cushion portion 118 can be configured as a single air cushion having a mat shape in some cases. When the mat-shaped air cushion is used, the stability of the conveyed product before the inner bag is brought into a substantially vacuum state is increased.

  The air cushion part 110 will be described. The air cushion part 110 is configured by arranging four air cushions 110A to 110D in a column at predetermined intervals on the left side face part 106A. Each of the air cushions 110A to 11D is a rod-shaped body (columnar body), and is configured to bulge in and out of the base sheet 102 as shown in FIG.

  Adjacent four air cushions 110A to 110D communicate with each other through a plurality of communication ports 120 as shown in FIG. Adjacent air cushions communicate with each other through the ridgeline portion 104a to the air cushion portion 112 provided on the adjacent surface portion (front surface portion) 106B. Therefore, a plurality of communication ports 122 are provided so as to straddle the ridgeline portion 104a.

  A similar communication port 120 is also provided between the plurality of air cushions 112A to 112D constituting the air cushion portion 112 provided on the front face portion 106B. The front surface portion 106B and the right side surface portion 106C and the right side surface portion 106C and the rear surface portion 106D are also in communication with each other via the ridgeline portions 104b and 104c.

  In addition to these configurations, in this example, the air cushion 110D formed on the left side surface portion 106A and the air cushion 118 (118A formed on the bottom surface portion 106E also on the ridgeline portion 104d between the left side surface portion 106A and the bottom surface portion 106E. ) Is provided.

  In this example, a single air injection portion 130 is provided on the upper end side of the air cushion 110A formed on the left side surface portion 106A. A configuration example of the air injection unit 130 will be described with reference to FIG.

  The air injection part 130 has a small-diameter communication pipe 132 formed of plastic, and the communication pipe 132 is attached so as to penetrate the welding part 140 of the air cushion 110A. An adhesive or the like is used so that one end face of the two film-like tongue pieces 134 (134a, 134b) welded to the tip end of the communication tube 132 and located in the air cushion 110A. And fixed.

  The distal end surfaces 135a and 135b of the tongue pieces 134a and 134b attached to the communication pipe 132 are opened, and the other end of the communication pipe 132 is engraved with a screw 136 as shown in the figure, and a cap 138 is screwed here. Combined.

  When the air injection part 130 is configured in this way, the tip surfaces 135a and 135b of the tongue pieces 134a and 134b are in close contact with each other due to the internal pressure of the air cushion 110A. Therefore, it is blocked from the outside air, and the internal air does not leak to the outside through the air injection portion 130.

  On the other hand, if the cap 138 is removed and air is sent from the communication pipe 132, the front end surfaces 135a and 135b of the tongue pieces 134a and 134b are opened, and a predetermined amount of air can be injected into the air cushion. Therefore, since the tongue piece 134 functions as a check valve, the air injection part 130 functions as an injection port with a check valve.

  As shown in FIG. 9, the plurality of air cushions 110 </ b> A to 110 </ b> D constituting the air cushion portion 110 communicate with each other through the communication port 120, and the adjacent air cushion portions 112 to 118 also communicate with each other. When air is injected from the air injection unit 130, a predetermined amount of air can be injected into all the air cushion units 110 to 118. The air injection amount is determined by the volume of the inner bag 10.

  The above-described inner bag 10 is temporarily fixed (temporarily fixed) with the outer bag 100. Therefore, as shown in FIG. 8, a temporary fixing means 142 is provided between a predetermined position on the outer peripheral surface of the inner bag 10 and a position on the inner peripheral surface of the outer bag 100 facing the predetermined position. In this example, the temporary fastening means 142 is configured by the surface fastener 144A attached to the inner bag 10 and the air cushion in this example, the surface fastener 144B attached to the outer circumferential surface of the air cushions 110B and 114B in the second row.

  By providing the temporary fixing means 142, for example, when the transported object 60 is stored in a state where the inner bag 10 is attached to the outer bag 100, the transported object 60 can be easily stored. Moreover, since loss of the inner bag 10 can be prevented, it is convenient in terms of management.

  In addition, since a gap is formed between the bottom portion of the inner bag 10 and the bottom portion of the outer bag 100, it is possible to prevent an impact from directly acting on the inner bag 10 when the transport container 1 is dropped.

  As shown in FIG. 1, handles 126a and 126b are provided on the opening 100a side of the outer bag 100 in consideration of carrying.

  Now, an example in which the transported object 60 is packed using the transport container 1 composed of the inner bag 10 and the outer bag 100 configured as described above is shown in FIG. FIG. 11 shows a state in which the inner air of the inner bag 10 has already been removed to be in a substantially vacuum state and stored in the outer bag 100. Therefore, air has not been injected into the outer bag 100 yet. Therefore, the inner bag 10 and the outer bag 100 are temporarily fixed by the temporary fixing means 142.

  In the state of FIG. 11, air is injected into the air cushion portion 110 of the outer bag 100. An air compressor (not shown) or the like may be used for air injection. Air can be injected into all the air cushion portions 110 to 118 by air injection from one place.

  When air is injected, each air cushion (110A, etc.) bulges as shown in FIG. 12, and the entire inner bag 10 is pressed by the bulged air cushion (110A, etc.). It is fixed to the bag 100. The way the air cushion bulges follows the shape of the inner bag 10 facing each air cushion (110A, etc.).

  As described above, by the cooperation of the plurality of air cushions (110A and the like) and the cushioning sheet 14 of the inner bag 10, the conveyed product 60 in the inner bag 10 is almost certainly protected from an external impact. Due to the double buffering effect, the impact resistance is greatly improved. Therefore, even if some external impact is applied to the outer bag 100 due to dropping during transportation or collision with other objects, there is no possibility that the conveyed goods are damaged. Of course, even if an external impact is applied, the inner inner bag 10 does not protrude from the opening 100a (FIG. 12) of the outer bag 100 or jump out.

  When unpacking the conveyed product 60, the air is first removed from the outer bag 100. By opening the tongue piece (check valve) 134 in the air injecting portion 130, all the air filled in the air cushion portions 110 to 118 can be exhausted. By removing the air, the inner bag 10 becomes free, so that the inner bag 10 is stored in the outer bag 100 or is removed from the outer bag 100 using the slider 20C. Open the opening 16. Thus, since air enters the inner bag 10, the conveyed items 60 become free. Thereafter, the conveyed product 60 in the inner bag 10 is taken out.

  Since the inner bag and the outer bag can be reused as long as they are not damaged, a reusable transport container can be provided. Since the inner bag 10 is a bag body provided in a box shape as shown in FIG. 2, the inner bag 10 can be folded. Similarly, since the outer bag 100 can be easily folded if the air is removed, the transport container 1 is stored in a folded state or delivered to another department.

  FIG. 13 shows another example of the inner bag 10. In this example, the buffer sheet 14 attached to the inner bag 10 is extended to a part of the opening 16. In this way, even the top surface side of the conveyed product 60 stored on the uppermost surface can be protected by the buffer sheet 14.

FIG. 14 is another example of the buffer sheet 14. In this example, a large number of hemispherical air bags 38 are formed on both the upper and lower surfaces of the base 36.
When air bags 38 are formed on both sides in this way, for example, when air is sucked in a state where the conveyed product 60 is separated as shown in FIG. Enters. In such a case, the transported objects are naturally integrated, but they are integrated via the air bags 38, 38 on both sides, though partly. In such a case, a higher buffering effect than in FIG. 7 can be expected.

FIG. 16 shows another example of the air injection part 142. FIG. 10 illustrates a structure using the communication pipe 132, but FIG. 16 illustrates a structure in which the communication pipe 132 is not used.
As shown in FIGS. 16 and 17, the air injection part 142 with a check valve is configured by using two strip-shaped soft films (thin soft sheets) 146a and 146b. Therefore, these films 146a and 146b are overlapped, and the upper and lower welded portions 148 and 148 as shown in FIG. 16 are used to weld only the upper end ends of both films 146a and 146b, and the welded portion 140 of the air cushion 110A is welded. Insert to straddle.

  The welding widths of the welded portions 148 and 148 are set so that the width (diameter) of the non-welded portion is substantially the same as the tube diameter of an air injection tube described later. In this example, only a predetermined range straddling the welded portion 140 is selected to have a width that is substantially the same as the tube diameter of the air injection tube, and other portions are selected to be wider than the tube diameter of the air injection tube. This is to prevent air leakage during air injection and to facilitate intubation and insertion / removal of the air injection tube.

  With this configuration, both the left and right ends of the air injection portion 142 are opened, and one end (left end) thereof is exposed from the air cushion 110A, and the other end (right end) is present inside the air cushion 110A. The length existing inside is such a length that the two films 146a and 146b can be kept in close contact with each other by the internal pressure. If it does so, the air inject | poured in the air cushion 110A will not leak outside via this air injection part 142 in a normal state. Therefore, a check valve function can be provided.

  When air is injected, an air injection tube 149 is inserted into the air injection part 142 as shown in FIG. At this time, it inserts so that the front-end | tip part of the air injection pipe | tube 149 may protrude in the air cushion 110A from the right end surface of film 146a, 146b. After that, if air is sent through the air injection tube 149, air can be injected into the air cushion 110A, thus functioning as an air injection unit. After the air injection, the air injection pipe 149 is removed to shut off from the outside.

  In the above embodiment, the substantially vacuum state does not necessarily indicate an absolute vacuum state. In short, the air inside the inner bag with the opening closed is discharged, and the inner bag and the buffer sheet attached to the inner bag follow the outer surface of the transported item stored inside the inner bag and closely adhere to each other It is sufficient that the vacuum state is sufficient.

  Moreover, although demonstrated using the example which formed the hemispherical air bag in the buffer sheet, the air bag of a buffer sheet is not limited to hemispherical, The air bag which bulges in the substantially cylindrical shape or the substantially trapezoid shape. It may be.

  The present invention can be applied to a small article transport container for home use or business use.
