Description

201206781 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a bag unit that is used for delivery of articles for home delivery. [Prior Art] When transporting articles, in order to effectively protect the articles from impact or vibration during transportation, cushioning paper or plastic sheets or other cushioning materials are usually used to pack the articles, and more necessary Into the sputum, the items will not move and will be wrapped in the outer box. In Patent Document 1, a bag that uses the heat insulating effect of the foamed granules is used as a bag for transporting articles, but an insulated bag for the purpose of using a shopping bag or the like is used. The heat insulating bag is a double bag having an inner bag portion and an outer bag portion which are deformable and freely formed with a granular body accommodating portion, and the heat insulating bag is characterized in that: the heat insulating bag is formed to be storable, and the two bag portions are formed At least the outer bag portion constitutes a non-air permeable bag body; and the plurality of foamed granules that are accommodated in the granular body accommodating portion and are condensed in the accommodating portion to be in a sealed state and in a solidified state And an air supply and exhaust port that is connected to the granule housing portion and provided in the bag body, and has an intake valve that maintains an exhaust state of the granule housing portion. According to the heat-insulating bag described in Patent Document 1, the following effects are obtained, that is, the plurality of foamed granules accommodated in the granule accommodating portion are solidified along the shape of the object to be insulated, thereby eliminating The heat loss caused by the convection of the air around the insulation is carried out in the bag body, and is insulated by the foamed granular 201206781 body group, so that the temperature change of the insulation can be suppressed for a long time, and the foamed particles in the above-mentioned cured state can be suppressed. The body is positioned by the heat retaining body so as not to move in the bag body, thereby preventing the deterioration of the quality of the heat insulating material caused by the movement of the heat insulating material. In the heat insulating bag described in Patent Document 1, the heat insulating effect of the foamed granular body group which is solidified along the shape of the heat insulating material is used for heat preservation of the heat insulating material, but foamed granular form in a cured state. The body group is not only a heat insulating effect, but also a cushioning effect can be expected. The foamed granular body in the cured state is used as a cushioning body to position the article so as not to move in the bag body, thereby protecting the home delivery device. In view of the impact of the articles to be transported from the outside, a large effect can be expected. Based on the above findings, the inventors of the present invention first developed various protective mats for bagging articles by using a bag filled with airtightness of cushioning particles as a pad. According to the protective pad, by bringing the surface of the pad into contact with the surface of the bag and exhausting the bag, the pad can be solidified by mimicking the surface shape of the article to support at least one side of the article, and borrow The cushioning effect is produced by the curing of the buffer particles, and the article can be effectively protected from the impact or vibration received during transportation. In fact, when the protective pad is used for home delivery, the pad is usually wrapped with a pad and stored in a shaped outer case. The use of the shaped outer case is because the shape can be easily loaded on the truck or stacked easily during storage. That is, the article is specifically packaged in the protective pad to protect the article from vibration or shock during handling, and the outer casing only secures the protective pad containing the article and is used for the purpose of maintaining the shape.

S -6- 201206781 The buffer particles are used as a buffer body to be filled in a protective pad in a gas-tight bag. By venting the bag, the buffer particles can be solidified by mimicking the surface shape of the article, and the bag is raised. The filling density of the inner buffer particles, whereby the retention and cushioning effect of the article can be obtained. However, when the protective pad is actually used in the bag of the home delivery device, in order to keep the shape of the carrier in shape, it is preferable to pack the bag. The protective pad after exhausting the item and venting is stored in the shaped outer box. Then, in order to make the articles accommodated in the outer box stable in the outer box, it is necessary to fix the articles with the binding tape and to vent the protective pad. However, since the protective pad is solidified by mimicking the shape of the article, the shape is usually amorphous, and the length of the binding tape must be adjusted and locked in accordance with the difference of the article, and there are many problems in the operation of the bag. [PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] JP-A-2001 - 32 1 2 1 7 [Patent Document 2] Japanese Patent No. 284765 1 (Summary of the Invention) The problem to be solved is that when the protective pad which is wrapped and deflated is fixed in the shaped outer casing, since the shape of the protective pad which is solidified in the shape of the counterfeit article is usually amorphous, it is required The length of the strap is adjusted and locked according to the different items, and there is a problem with many procedures for the baggage operation 201206781. (Technical means for solving the problem) In order to solve the above problems, the bag unit of the present invention is characterized in that the article can be held between the protective pads which are bent in half and the inside of the pad is exhausted. The article is fixed between the protective pads and then directly clamped between the lower plate and the upper plate of the outer box, thereby being able to wrap the articles in the outer box without cumbersome procedures. Effect of the Invention: According to the bag unit of the present invention, the storage item is simply clamped between the protective pads folded in half, and the inside of the protective pad is exhausted to solidify the protective pad, and then directly clamped to the outer box. It can be locked between the lower plate and the upper plate and covered with the outer box, so the procedure of the bag can be simplified. Especially for the sake of safety, it can be stored more securely by using the strap, but the strap does not need to be tightly fixed to the outer box, and it is only necessary to suppress the offset in the front, rear, left and right directions. The protective pad holding the article and being cured is pressed between the lower plate and the upper plate, and is stably held in a fixed position in the outer casing by the elasticity of the outer casing. Furthermore, by covering the outer box and locking, a buffer space can be formed below the lower plate and above the upper plate, and the buffer space can be ensured at the 4th circumference of the outer case, so that even if dropped or dumped during handling Etc., so that a strong impact from the outside acts on the outer box, and the impact can also be effectively absorbed by the buffer space, and the impact is hardly transmitted to the article wrapped by the protective pad, and

S -8- 201206781 Protects stored items efficiently and safely. The pumping of the inside of the protective pad is performed by using a part of the buffer space formed on the four peripheral edges of the box body and the lid as a storage space, and the pump is stored in the outer box in advance, thereby Can respond quickly. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail. (1) Packet unit In Fig. 1, the packet unit of the present invention is constituted by a combination of the protective pad 10 and the outer case 11. The protective pad 10 is held by the article to be stored, and the outer case 1 1 is provided such that the plate 14 and the upper plate 16 are oriented to each other by the elastic material of the outer casing. The lower plate 14 and the upper plate 16 are in a state in which the upper and lower surfaces of the protective pad 10 that holds the article are pressed and fixed in a fixed position in the outer casing 1 1 in the state in which the elastic force acts. (2) Protective pad In Fig. 2, a protective pad (hereinafter abbreviated as a pad) is composed of a combination of an outer bag 1, an inner bag 2, and a buffer particle 3 filled in the inner bag 2. In the present embodiment, the outer bag 1 overlaps the pair of outer layer sheets 1a, 1b having airtightness up and down, and seals the peripheral edge to be airtight and processed into a flat rectangular bag shape. A valve 4 is attached to a portion of the sheet surface of the outer bag 1. The pad 1 is bent in half and is housed in the outer case in a state in which the article is held. Therefore, in the present embodiment, the shape of the outer case is a rectangle. 201206781 The inner bag 2 is a bag having elasticity and air permeability, and is filled with a certain amount of buffer particles 3, and the buffer particles 3 are preferably filled in the inner bag 2 in an unbiased manner and kept. A flat pad of a certain thickness. In the present embodiment, the inner bag 2 is formed by sewing a peripheral edge of a pair of rectangular sheets having air permeability into a flat rectangular bag shape which is smaller than the outer bag 1 by one turn. The inner bag 2 filled with the buffer particles 3 is inserted into the outer bag 1. The inner bag 2 has a joint 5 on the sheet surface above and below the formed bag. The joint 5 is a portion that covers the entire surface of the sheet above and below the inner bag 2, and integrally joins the minute ranges at regular intervals in the longitudinal and lateral directions as shown in Fig. 2 . When the inner bag 2 is viewed from above at each joint 5 as shown in Fig. 3(a), the vertical and horizontal positions of each row in the row and the direction are shifted from each other and scattered, but this can also be as shown in Fig. 3. (b) is arranged neatly in the vertical and horizontal directions. The inner bag 2 can be obtained by sewing the periphery of the air permeable sheet or by joining the bag-shaped woven fabric to the main portion. The sheet of the inner bag 2 used in the embodiment is made of a fiber-based woven material. A three-dimensional braid composed of a table woven material, a woven material, and a connecting line connecting the woven materials. For example, there is a three-dimensional knitted fabric "Double Raschel (registered trademark)" of Asahi Kasei Co., Ltd. (refer to Patent Document 2). According to the three-dimensional knit fabric, a plurality of partitions of three or more points which are close to each other, in this embodiment, are partitions surrounded by four joints 5, 5, 5, and 5 as shown in FIG. , which substantially constitutes an independent structure, and the woven material is stretchable, so that a certain amount of the buffer particles 3 can be substantially enclosed in the separation zone connecting the joints 5 so as to be filled with the buffer particles 3 The inner bag 2 is flat and has a substantially constant thickness. ·

S -10- 201206781 Further, when the above-described three-dimensional braid is used, initially, when the buffer particles 3 are sealed in the inner bag 2, an opening (not shown) is provided in a part of the inner bag 2, and high-pressure air is taken from the opening. The buffer particles are pressure fed in, and an appropriate amount is equally sealed in the separation zone joining the joints 5. The opening is then closed to prevent loss of buffer particles. The sheet formed above and below the inner bag 2 must have stretchability, but does not necessarily have to be a braid. Any fabric that is stretchable can be used. The buffer particles 3 are elastic or stretchable particles, and granules of foamed polyethylene or expanded polystyrene can be used. Although the particle size of the particles is not limited, the smaller the particle size, the more the shape of the article can be obeyed. By inserting the inner bag 2 filled with the air permeability of the buffer particles 3 into the airtight outer bag 1, the buffer particles 3 can be dispersed in a sealed space of the outer bag 1 at a certain amount and filled. The layer thickness of the buffer particles 3 is limited by the height of the inner bag 2, the inner bag 2 becomes a buffer layer having a substantially constant thickness, and the outer bag 1 and the inner bag 2 are combined to form a flat pad. (3) The valve 4 provided on the sheet surface of the valve outer bag 1 is composed of a combination of a backflow prevention valve and an intake valve. Fig. 5 is a view showing an example of the configuration of the valve 4. The valve 4 is composed of a combination of the backflow prevention valve 6 and the intake valve 7, the intake valve 7 is assembled in the flow path at the inner center of the cylindrical valve casing 8, and the backflow prevention valve 6 is assembled to the concentric periphery thereof. The flow path formed by the position on the circle. The backflow prevention valve 6 is opened by the suction force when the suction force of the pump acts, and is closed after the exhausting, and the valve is closed after the exhaust, so that the external air is introduced to the resistance -11 - 201206781 Into the protective mat ι, the suction valve 7 manually rotates the cover 9 provided at the upper end of the valve box 8 and thereby opens the valve to open the valve, and the external air can be introduced into the exhaust pad 10 Inside. After the venting of the pad 10, the amount of content is reduced, so that the density of the buffer particles in the bag is increased, and as a result, the pad is cured. The valve used in the present invention mainly combines the backflow prevention valve and the inhalation valve to exhaust the gasket in the bag when the article is wrapped, so that the pad is softened when the bag is opened, and the pad is softened. Limited to the above configuration. In the operation of the bale, it is preferable to construct as much as possible. (4) The outer casing 11 is made of, for example, a resilient material such as a synthetic resin covered with a soft cloth or the like, as shown in the first drawing, which is an open square shape from the top. The box body 1 2 and the lid body 13 which is openably and closably attached to the upper edge opening edge of the box body 1 2 are combined. The case body 1 2 accommodates the protective pad of the wrapped article, and the cover 13 covers the opening edge of the case body 12. A fixing member 21 for sealing the opening edge and locking is attached to the lid body 13 and the box body 12. However, the locking means of the cover 13 and the case body 12 are not limited to the fixing member, and may be a bundle known as a lock. As shown in Fig. 6 (a) and (b), the case body 12 and the lid body 13 have concave portions 12a and 13a in the central portion of each outer surface, and the shape of the concave portion is patterned to form a projection on the four peripheral edges of the concave portion. The ribs 12b, 13b of the strip. The recess 12a formed in the outer central portion outside the case body 12 is formed in the inside of the case body 12 to form a lower plate 14 which protrudes in a square shape in the middle.

S -12- 201206781, when the ribs l2b' of the four-segment ridges are viewed from the inside of the box body, the opposite annular grooves 17 are formed at the four circumferential edges of the lower sill. Similarly to the lid body 13, the recessed portion 13a formed in the central portion of the outer surface is formed as a square upper plate 16 projecting toward the center of the box body, and a rib portion 3b of the protrusion of the four peripheral edges, from the cover body When viewed inside, the shape of the upper plate 16 is mimicked to form the opposite annular groove 15 formed on the four weeks. In the present embodiment, the upper plate 16 is formed by deforming a part of the cover 13 and retaining the shape by projecting into the rib-shaped arms 15a in the annular grooves 15 on both sides, and the lower plate 14 is such that the case body 12 is A part of the deformation is maintained in shape by projecting into the ribbed arms 17a in the annular grooves 17 on both sides. Therefore, when the case body 12 is covered by the lid body 13, the lower plate 14 and the upper plate 16 face each other upward and downward at a predetermined interval. On the outer periphery of the four weeks, the upper and lower annular grooves 15 and 17 are oriented toward each other. A ring-shaped space is formed between the two. As will be described later, the space of the upper and lower annular grooves 15, 17 serves as a buffer space. Further, the ribs 1 2b and 1 3b forming the ridges of the annular grooves 15 and 17 are elastically imparted by the elasticity of the material of the outer casing, and the elastic action allows the vertical direction to be The lower plate 14 and the upper plate 16 are respectively supported by the upper displacement. (5) The essentials of the article Next, the method of transporting the article using the bag unit of the present invention will be described. In Fig. 7(a), the lid body 1 is first opened and the box body 12 is opened, and the pad 10 is folded in half and inserted into the box body 12, and is supported by the lower plate 14 of the box body 12. In this state, the upper portion of the pad 10 is opened and the article is placed on the lower portion of the pad 10 from -13 to 201206781. Next, as shown in Fig. 7(b), the upper layer portion of the pad 10 is folded over the article stack, and the article stack is held between the upper and lower layers of the pad 10, as shown in Fig. 7(C). It is shown that the suction port of the pump 18 is inserted into the valve 4 attached to a part of the pad 10, the handle 19 is operated, and the inside of the outer bag 1 of the pad 1 is exhausted. In this case, a reciprocating pump is used, so the handle is used to advance and retreat to vent the air in the pad. Thereby, as shown in Fig. 7(d), since the volume of the pad 10 is reduced, the density of the buffer particles 3 in the pad 10 is increased, and the article is held between them. Cured. In this state, as shown in Fig. 7(e), the cover 13 can be pushed to the pad 10 by pressing the surface of the pad attached to the binding body 20 of the case body and holding it in a fixed position as necessary. The upper portion is poured to cover the tank body 12, and as shown in Fig. 7(f), the opening of the outer casing 11 is sealed with a fixing member (omitted from the drawing), and the bag is locked to complete the bag. The reinforcing pad is held between the lower plate 14 of the case body 12 and the upper plate 16 of the lid body 13 in a state in which the elasticity of the ribs 12b and 13b of the ridges acts in the vertical direction. It is stably housed in a fixed position of the outer casing 11. As shown in Fig. 8, the pump 18 is appropriately housed in a buffer space formed by the peripheral edges of the casing main body 1 2 and the lid body 13 and stored. That is, the buffer space formed by the four peripheral edges of the tank main body 1 2 and the lid body 13 is used as a storage space for pumping. In the present invention, the binding tape 20 is not used for the purpose of fixing the protective pad surrounding the storage article to the outer casing, but is used in an auxiliary position to stay at the fixed position of the outer casing. The article is stored in the outer box 1 1 and shipped as a delivery item.

S -14- 201206781, even if it is subjected to impact or vibration during transportation, the article will not float or rotate in the outer casing 11 even if the outer casing 11 falls from a high place or is strongly impacted from the outside, Most of the impact force will act on the annular rib of the outer casing for 4 weeks, and will be absorbed by the space of the lower recess on the outer casing and the space inside the annular rib of the four weeks. The strong impact force will not be directly packaged. The object in the pad 1 Μ acts. In particular, even if the vibration or impact applied during transportation acts on the pad 10 in the outer casing, the vibration or impact can be effectively absorbed by the buffer layer of the buffer particles 3 solidified in the pad 10. . (6) The method of opening the bag When opening the bag of the goods to be delivered to the destination, first open the cover 13 of the outer box 11, release the band 20, pull up the inhalation valve 7 to open the flow path, and pass the The flow path introduces external air into the pad 10. Due to the inflow of the outside air, the capacity in the bag 1 outside the pad 1 is increased, the density of the buffer particles 3 is reduced, and the tension of the pad 10 is softened and softened. The pad 10 is opened and the article 取出 is taken out of the outer box 11. (7) Simplification of the article package Fig. 9 shows another embodiment of the present invention. In this embodiment, a portion of the lid body 13 is opened so that the valve 4 of the pad 10 faces the small hole 22 outside the lid body 13 (see Figs. 9(b) and (c)). In the present embodiment, when the article is wrapped, as shown in Fig. 9(a), in the state in which the lid 13 of the outer casing 11 is opened, as shown in Fig. 9(b), the valve of the pad 1 is closed. 4 facing the small hole 22 of the cover 13 and extending across the box body 12 and the cover 13

V -15- 201206781 Exhibition mat 10. Next, the article stack is placed in the center of the pad 10 laid in the box body 12, and then the lid body 13 is tilted and the article stack is held between the folded pads 10 as shown in Fig. 9(c). After the article is clamped between the upper and lower layers, the lid is closed, and as shown in Fig. 9(c), the suction port of the pump 18 is inserted into the valve 4 facing the small hole 22 of the lid body 13, and the handle is operated. 19 and exhaust the inside of the outer bag 1 of the pad 10 . Thereby, the pad 10 is made to conform to the inner shape of the outer case 1 1 to reduce the volume, and is solidified while sandwiching the article Μ therebetween. According to the present embodiment, if the cover is covered and the inside of the cover is exhausted while the article is held between the pads, the pad can be naturally cured in conformity with the inner shape of the outer case 11, and the article is stably Keep it inside the outer box, even without the need to bundle the pads as shown in Figure 8. (8) Function of constituent member In the present invention, the pad is a support pad for the article. By holding the article on the pad and curing, the article and the pad can be integrated, if the box body is covered by the cover body, and the article is clamped between the upper plate and the lower plate of the outer box with each support pad Then, if the object is locked, the article can be pressed in the state of being clamped and held in the fixed position of the outer box by the elastic action between the upper plate and the lower plate, and can be bundled as necessary, or can be directly locked to the bag. This simplifies the baggage process of the item. In particular, when the article is held between the pads, the gap between the upper plate and the lower plate is thinner, and can be pressed by the binding tape to be held in a fixed position. (9) Improvement of impact mitigation effect

S-16-201206781 Fig. 10 shows an example in which the arms 15&1 and the ribs are surrounded by the concave portion 13a of the upper plate of the rib 13b of the inner and outer ribs 13bi. Although the bottom of the box body is omitted from the illustration, the same treatment is applied. In order to alleviate the need to stably hold the article held by the protective pad, the outer casing is kept in shape, and the body from the collision surface is prevented as much as possible to avoid the impact of the impact on the stored article. It is effective to provide the ribs in the cover portion as the countermeasure. In either case, the upper and lower buffer spaces of the box body and the lid body are in a state of being fixed by the pad and the buffer space of the side of the ring cap on the upper side of the cover body for 4 weeks.
