Description

  The present invention relates to a packing unit used for delivery of goods, particularly goods for home delivery.

  When transporting goods, in order to effectively protect the goods from shocks and vibrations during transportation, the goods are usually packed with cushioning paper, plastic sheets or other cushioning materials, and further required. Depending on the situation, the articles are stuffed so as not to move and packed in an outer box.

  Although it is not a bag for carrying goods, Patent Document 1 describes a bag that uses the heat insulating effect of foamed granular material as a heat insulating bag intended for use as a shopping bag or the like. This heat insulation bag is a double bag having an inner bag portion and an outer bag portion that can be freely deformed by forming a granular material accommodating portion between them, and is formed so as to be able to hold a heat insulation material, and of both the bag portions. A bag main body in which at least an outer bag portion is non-breathable, and a myriad of foamed granular materials that are accommodated in the granular material accommodating portion and gather together in a close contact state as the accommodating portion is degassed. A heat insulating bag comprising: an air supply / exhaust port that is provided in the bag main body and communicates with the granular material accommodating portion and that holds the granular material accommodating portion in a deaerated state. is there.

  According to the heat insulating bag described in Patent Document 1, the innumerable foamed granular material accommodated in the granular material accommodating portion is solidified so as to follow the shape of the material to be insulated, so that the temperature is maintained in the bag body. In addition to eliminating heat loss due to convection of air around the object and heat insulation with the foam granule group, it is possible to suppress the temperature change of the object to be kept for a long time, and to keep the object to be kept warm with the solidified foam granule. It is emphasized that the positioning of the bag body so as not to move prevents the quality deterioration of the warm object based on the movement of the warm object.

  The heat insulating bag described in Patent Document 1 is a foamed granular material in which the heat insulating effect of the foamed granular material group is utilized for heat retention of the heat-insulated material as a solidified state along the shape of the material to be heat-insulated. The group can expect not only a heat insulating effect but also a buffering effect, and the ability to position the article so that it does not move within the bag body using the solidified foamed granular material as a buffer, so that the article transported as a courier is received from the outside A great effect can be expected to protect against impacts.

  Based on the above findings, the inventors have previously developed various protective mats for packing articles using an airtight bag filled with buffer beads as a mat. According to this protective mat, the surface of the mat is brought into contact with the surface of the packaged article, and the inside of the bag is deaerated, so that the protective mat solidifies in the shape of the surface of the article and holds at least one surface of the article. At the same time, a buffering action is produced by the solidification of the buffer beads, so that the article can be effectively protected from shocks and vibrations received during transportation.

  In order to actually use a protective mat for home delivery, it is usual to pack an article with a mat and store it in a fixed outer box. The reason why the fixed outer box is used is to facilitate loading on a truck and storage by standardizing the shape. That is, the articles are packaged exclusively in a protective mat and protected from vibration and impact during transportation, and the outer box is used for the purpose of simply fixing the mat on which the article is packaged and keeping it in a fixed shape.

  By the way, a protective mat filled with buffer beads as a buffer in an airtight bag is degassed to solidify the buffer beads in the shape of the surface of the article. Increasing the packing density of the body beads provides the retention and cushioning effect of the article, but in order to actually use the protective mat for courier packaging, the article must be It is desirable to store the protective mat wrapped and deaerated in a fixed outer box.

  And in order to stabilize the articles | goods accommodated in the outer box in an outer box, it is necessary to fix the protective mat which wrapped the articles | goods using the binding band etc. and was deaerated. However, since the protective mat is solidified in the shape of an article, the shape is usually indeterminate, and the length of the binding band must be adjusted for each article and tightened. is there.

JP 2001-321217 A Japanese Patent No. 2847651

  The problem to be solved is that when the protective mat that has been degassed by wrapping the article is fixed inside the fixed outer box, the shape of the protective mat that is solidified in the shape of the article is usually indefinite. In addition, the length of the binding band must be adjusted and fixed for each article, and the packaging work is troublesome.

  In order to solve the above-mentioned problems, the packing unit according to the present invention sandwiches an article between two protective mats, deaerates the inside of the mat, fixes the article between the protective mats, and directly under the outer box. By sandwiching between the plate and the upper plate, the greatest feature is to pack the articles in the outer box without requiring troublesome work.

  According to the packing unit of the present invention, the stored article is sandwiched between the protective mats that are folded in two, the inside of the protective mat is deaerated to solidify the mat, and is directly between the lower plate and the upper plate of the outer box. Since it suffices to sandwich and cover and lock, packing work can be simplified. However, as a precaution, it can be stored more stably by using a binding band. However, the binding band does not necessarily have to be fastened to the outer box, and it is sufficient to suppress the displacement in the front-rear and left-right directions. The protective mat solidified by sandwiching the article is pressed between the lower plate and the upper plate, and can be stably held at a fixed position in the outer box by the elasticity of the outer box.

  Furthermore, by covering and locking the outer box, a buffer space is formed below the lower plate and above the upper plate, and a buffer space is also secured on the four peripheral edges of the outer box. Even if a strong impact acts on the outer box from the outside due to falling or falling during transportation, the impact is effectively absorbed in the buffer space, and almost no impact is transmitted to the article wrapped in the protective mat, The stored items can be protected effectively and safely. In addition, the pump that deaerates the inside of the protective mat uses a part of the buffer space formed at the four peripheral edges of the box body and the lid as a storage space, and stores the pump in the outer box. You can respond quickly when necessary.

Hereinafter, embodiments of the present invention will be described in detail.
(1) Packing unit In FIG. 1, the packing unit by this invention consists of a combination of the protection mat 10 and the outer box 11. In FIG. The protective mat 10 holds an article to be stored, and the outer box 11 is a set of a lower plate 14 and an upper plate 16 each having a spring action of the material of the outer box, as will be described later. Have face to face. The lower plate 14 and the upper plate 16 are transport boxes that pressurize and hold the upper and lower surfaces of the protective mat 10 sandwiching an article in a state where a spring force is applied and hold the protective mat 10 in a fixed position in the outer box 11.

(2) Protective mat In FIG. 2, a protective mat (hereinafter abbreviated as “mat”) 10 comprises a combination of an outer bag 1, an inner bag 2, and buffer beads 3 filled in the inner bag 2. . In this embodiment, the outer bag 1 is formed into a flat rectangular bag shape by overlapping a pair of air-tight outer layer sheets 1a and 1b vertically and hermetically sealing the periphery. A valve 4 is attached to a part of the seat surface of the outer bag 1. Since the mat 10 is folded in two and accommodated in the outer box with the article sandwiched therebetween, it is rectangular in this embodiment according to the shape of the outer box.

  The inner bag 2 is a breathable bag having elasticity, and is filled with a fixed amount of buffer beads 3 therein, but the buffer beads 3 are filled evenly in the inner bag 2 and are constant. It is desirable to retain the shape on a flat mat having a thickness. In this embodiment, the inner bag 2 is processed into a flat rectangular bag shape that is slightly smaller than the outer bag 1 by stitching the peripheral edges of a pair of breathable rectangular sheets. The inner bag 2 filled with the buffer beads 3 is inserted into the outer bag 1. The inner bag 2 has a junction 5 on the upper and lower sheet surfaces forming the bag. The junction point 5 is a portion in which a minute range is integrally coupled at regular intervals in the vertical and horizontal directions as shown in FIG. 2 over the entire upper and lower sheet surfaces of the inner bag 2. 3A, when the inner bag 2 is viewed from above as shown in FIG. 3A, the vertical and horizontal positions are shifted from each other for each column in the matrix direction. They may be aligned vertically and horizontally as shown in (b).

  The inner bag 2 can be obtained by stitching the periphery of a breathable sheet or joining the essential parts of a bag-like knitted fabric. The sheet of the inner bag 2 used in this embodiment has a fiber yarn. A three-dimensional knitted fabric composed of a front knitted fabric and a back knitted fabric of the knitted fabric and connecting yarns connecting them is used. As such a knitted fabric, for example, there is a three-dimensional knitted fabric “Double Russell (registered trademark)” of Asahi Kasei Corporation (see Patent Document 2).

  According to such a three-dimensional knitting, there are substantially several sections of three or more points close to each other, in this embodiment, a section surrounded by four joint points 5, 5, 5, 5 as shown in FIG. Since the knitted fabric is rich in elasticity, a certain amount of the buffer beads 3 can be substantially confined in the section connecting the joint points 5, and the buffer beads 3 are filled. The inner bag 2 is flat and has a substantially constant thickness.

  Further, when using the above-mentioned three-dimensional knitting, when the buffer beads 3 are first sealed in the inner bag 2, an opening (not shown) is provided in a part of the inner bag 2, and the buffer beads are pumped from the opening with high-pressure air. Thus, an appropriate amount can be evenly enclosed in the section connecting the junction points 5. The opening is closed later to prevent the buffer beads from being washed away. The upper and lower sheets forming the inner bag 2 are required to have elasticity, but are not necessarily knitted. Even stretch fabrics can be used.

  The buffer beads 3 are particles having elasticity or stretchability, and a granular material of expanded polyethylene or expanded polystyrene is used. The particle size of the beads is not limited, but the smaller the particle size, the better the shape of the article. By inserting the air-permeable inner bag 2 filled with the buffer beads 3 into the air-tight outer bag 1, the buffer beads 3 are dispersed and filled into the sealed space of the outer bag 1 quantitatively. . The thickness of the layer of the buffer beads 3 is regulated 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 is combined with the inner bag 2 to form a flat mat.

(3) Valve The valve 4 provided on the seat surface of the outer bag 1 is a combination of a check valve and an intake valve. FIG. 5 shows an example of the structure of the valve 4. The valve 4 is composed of a combination of a check valve 6 and an intake valve 7, and the intake valve 7 is incorporated in a flow path at the center of the inside of the cylindrical valve box 8, and the check valve 6 is concentrically around the periphery. It is incorporated in the flow path formed at the position.

  The check valve 6 opens upon receiving the suction force of the pump when degassing the protective mat 10, and closes after degassing to introduce outside air into the mat 10. The intake valve 7 is pushed up and opened by manually rotating a cap 9 provided at the upper end of the valve box 8 to introduce outside air into the deaerated mat 1. It is what makes it possible. The degassed mat 10 reduces its internal volume and increases the packing density of the buffer beads in the inner bag, thereby solidifying the mat. The valve used in the present invention is basically a combination of a check valve and an intake valve, which is used to deaerate the inside of the mat when packing goods and solidify the mat, and to suck and soften the mat when unpacking However, it is not necessarily limited to the above structure. For packaging work, it is desirable to have a structure that is as easy to use as possible.

(4) Outer box The outer box 11 is made of a material having elasticity such as a synthetic resin whose outer surface is covered with a flexible cloth or the like, and its upper surface is opened as shown in FIG. It is comprised from the combination of the hollow square box main body 12 and the cover body 13 attached to the upper edge opening edge of the box main body 12 so that opening and closing is possible. The box main body 12 houses a protective mat that encloses an article therein, and the lid body 13 covers the opening edge of the box main body 12. The lid 13 and the box body 12 are attached with a fastener 21 that seals and locks the opening edge. However, the means for locking the lid 13 and the box body 12 is not limited to a fastener, and may be a known band with a key.

  As shown in FIGS. 6A and 6B, the box body 12 and the lid body 13 have recesses 12a and 13a in the central area of the outer surface, respectively, and project at the four peripheral edges of the recesses in the shape of the recesses. Ribbed ribs 12b and 13b are respectively formed.

  The concave portion 12a formed in the outer surface central region of the outer surface of the box body 12 forms a rectangular lower plate 14 projecting in a middle-high shape inside the box body 12, and the ribs 12b of the four peripheral ridges are When viewed from the inside of the box body, the half annular groove 17 is formed on the four peripheral edges of the lower plate 14. Similarly for the lid 13, the recess 13 a formed in the center area on the outer surface forms a rectangular upper plate 16 projecting in a middle-high shape toward the box body side, and ribs 13 b of four peripheral ridges are When viewed from the inside of the lid 13, the half annular groove 15 formed on the four circumferences of the upper plate 16 is formed. In this embodiment, the upper plate 16 is shaped by an arm 15a that is formed by deforming a part of the lid 13 and projecting into ribs in the annular grooves 15 on both sides, and the lower plate 14 is formed by the box body 12. Is retained by arms 17a that are partially deformed to project into ribs in the annular grooves 17 on both sides.

  Therefore, when the box body 12 is covered with the lid body 13, the lower plate 14 and the upper plate 16 face each other up and down at regular intervals. A space is formed. As will be described later, the spaces of the upper and lower annular grooves 15 and 17 become buffer spaces. Further, the ribs 12b and 13b of the ridges forming the annular grooves 15 and 17 are given a spring action by the elasticity of the material of the outer box, and the spring action causes the lower plate 14 and the upper plate 16 to move in the vertical direction, respectively. Supports relative displacement.

(5) The point of packing of goods Next, the point of transporting goods using the packing unit by the present invention is explained. 7A, first, the lid 13 is opened to open the box body 12, the mat 10 is folded into the box body 12, and the mat 10 is supported on the lower plate 14 of the box body 12. FIG. In this state, the upper layer portion of the mat 10 is opened, and the article M is placed on the lower layer portion of the mat 10. Next, an upper layer portion of the mat 10 is folded over the article M as shown in FIG. 7B, and a part of the mat 10 is used as shown in FIG. The suction port of the pump 18 is inserted into the valve 4 attached to, the handle 19 is operated, and the inside of the outer bag 1 of the mat 10 is deaerated. In this example, a reciprocating type pump is used, and therefore the handle is moved forward and backward to deaerate the air in the mat. As a result, as shown in FIG. 7D, the mat 10 has a reduced volume, so that the packing density of the buffer beads 3 in the mat is increased and the article M is solidified with the article M sandwiched therebetween.

  In this state, as shown in FIG. 7 (e), the mat surface is held in place by holding the mat surface with a binding band 20 attached to the box body as necessary, and the lid 13 is brought down on the upper surface of the mat 10 to bring it into the box. The main body 12 is covered, and the opening of the outer box 11 is sealed with a fastener (not shown) as shown in FIG. As a result, the article M is sandwiched between the solidified mats and pressed between the lower plate 14 of the box body and the upper plate 16 of the lid 13 with the elasticity of the ribs 12b and 13b of the ridges acting from the vertical direction. The outer box 11 is stably stored in a fixed position.

  As shown in FIG. 8, the pump 18 is appropriately housed and stored in a buffer space formed at the four peripheral edges of the box body 12 and the lid body 13. That is, the buffer space formed at the four peripheral edges of the box body 12 and the lid body 13 is used as a storage space for the pump. In the present invention, the binding band 20 is not intended to fix the protective mat holding the stored article to the outer box, but is used in an auxiliary manner to keep it in a fixed position in the outer box.

  The article M is stored in the outer box 11 and is transported as a courier cargo. Even if vibration or impact is applied during the transportation, the article M does not float and roll in the outer box. Even if the outer box 11 falls from a high place or receives a strong impact from the outside, most of the impact force acts on the annular ribs on the four circumferences of the outer box, and the upper and lower sides of the outer box A strong impact force is not directly applied to the article M wrapped in the mat 10 by being absorbed in the space of the recesses and the space in the annular ribs of the four circumferences. However, even if vibrations and shocks received during transportation act on the mat 10 in the outer box, the vibrations and shocks are effectively absorbed by the buffer layer of the buffer beads 3 solidified in the mat.

(6) Unpacking procedure To unpack the cargo delivered to the destination, open the lid 13 of the outer box 11, remove the binding band 20, push up the intake valve 7, open the flow path, Outside air is introduced into the mat 10 through the road. Due to the inflow of outside air, the capacity of the outer bag 1 in the mat 10 is increased, the packing density of the buffer beads 3 is decreased, the tension of the mat 10 is loosened and softened, and the mat 10 is easily opened to remove the article M. It can be taken out from the box 11.

(7) Simplification of packaging of goods FIG. 9 shows another embodiment of the present invention. In this embodiment, a small hole 22 that opens the valve 4 of the mat 10 to the outside of the lid 13 is opened in a part of the lid 13 (see FIGS. 9B and 9C). . In this embodiment, in order to pack the article, the valve 4 of the mat 10 is closed as shown in FIG. 9B with the lid 13 of the outer box 11 opened as shown in FIG. The mat 10 is spread across the box body 12 and the lid 13 so as to face the small hole 22 of the body 13. Next, the article M is placed in the center of the mat 10 laid in the box body 12, the lid 13 is tilted as it is, and the article M is sandwiched between the two folded mats 10 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 13 as shown in FIG. The inside of the 10 outer bags 1 is deaerated. As a result, the mat 10 is adapted to the internal shape of the outer box 11 to reduce its volume, and is solidified with the article M sandwiched therebetween. According to this embodiment, the article is covered in a state sandwiched between the mats, and if the inside of the mat is evacuated as it is, the mat is naturally solidified by adapting to the inner shape of the outer box, and the article is stable in the outer box. It is not necessary to bind the mats as shown in FIG.

(8) Function of component In the present invention, the mat is an article holder. If the article is solidified by sandwiching the article with the mat, the article is integrated with the mat, the box body is covered with a lid, the article is put together with the holder between the upper and lower plates of the outer box, and locked as it is Since the article is sandwiched between the mats and is held by the spring action between the upper plate and the lower plate and held in a fixed position on the outer box, the items are packed by simply tying them or locking them as they are This makes it possible to simplify the packaging of the goods. Of course, a product that is thinner than the gap between the upper plate and the lower plate with the article sandwiched between the mats can be held in place by holding it with a band.

(9) improved Figure 10 impact absorption effect surrounds the recess 13a to form a top plate of the outer box 11 of the inner and outer double in ribs 13b ₁ and 13b _2, the arms 15a ₁ on each rib 13b ₁ and 13b ₂ And 15a ₂ are shown. Although illustration is omitted, it goes without saying that the same measures are taken for the bottom of the box body. To alleviate the impact when dropping, keep the outer case in a fixed shape with the article sandwiched between the protective mats stably supported, and distribute the shock from the collision surface to the box body as much as possible to store the article. It is necessary to avoid the impact of impacts on. As a countermeasure, providing multiple ribs on the bottom of the lid and the box body is effective in improving the impact mitigation effect.

  In any case, the box body and the concave portion of the lid body become the upper and lower buffer spaces of the article in a state where the article is wrapped in a mat and held in a fixed position in the box, and the upper and lower annular grooves on the four sides are on the four sides of the article. Thus, the article can be effectively protected from an impact applied to the outer box. In the above embodiment, an example of packing a flat article such as a notebook computer has been described. However, two or more small digital cameras and electronic game devices are held in parallel between two folded mats. Of course, it can be packed in an outer box.

  The protective mat according to the present invention is used to deliver a product from a retail store or a mass retailer to a buyer. When a product is delivered from a user of the product to a repair center for repair of the product, the repaired product is repaired. It can be widely used not only for returning to the client, but also for moving goods by moving or courier, delivering goods from department stores, retail stores, and transporting goods and documents between factories and offices.
