Description

  The present invention relates to an assembly-type synthetic resin container in which a side plate is disposed on a flat rectangular bottom plate via a bent portion or a rotating shaft portion, and can be easily folded by operating a lock lever. More specifically, the present invention relates to an assemblable synthetic resin container equipped with a lock lever to which an IC tag that records container delivery, receipt, inventory management, customer information, and the like is attached.

  Conventionally, side plates are erected on the four sides of a bottom plate formed in a square shape through a bent portion or a rotating shaft portion, and the side plates are assembled with each other by a lock lever attached to the side plate. An assembly type synthetic resin container is used in which the side plates are disengaged by operation and the side plates are folded inward. Synthetic resin containers are widely used in place of cardboard boxes because they are excellent in durability and can be used repeatedly.

  In recent years, ISO packaging modules have been adopted as part of the rationalization of logistics for the dimensions of such assembly-type synthetic resin containers. The packaging module is a numerical value serving as a reference for obtaining a systemized transport packaging dimension for the purpose of improving the distribution efficiency by the unit load system, and common plane dimensions (length × width) are performed.

  The height of the assembly-type synthetic resin container body is changed depending on the articles to be stored. In consideration of the loading efficiency on pallets, etc. The dimensions are shared.

  On the other hand, in recent years, in the logistics industry, an IC tag is attached to a container to carry out logistics management. IC tag is attached to the container, and the time until delivery, receipt, inventory, and collection is recorded and the container is identified and managed, and the customer information is managed by recording the production area, market, mass retailer, processor, etc. ing.

  Then, when attaching such an IC tag, it has become a problem in which position of the assembly type synthetic resin container to be mounted. In order to solve such a problem, in Japanese Patent Application Laid-Open No. 2010-6391, in a foldable folding container, “the ID tag is formed in the lock release member storage portion region disposed in the vicinity of the upper end horizontal flange portion”. It has been proposed to be disposed in the ID tag storage recess.

JP 2010-6391 A

  In the folding container described in the above publication, the effect of preventing damage to the ID tag can be obtained by covering the ID tag with a lock release member. However, millions of assembly-type synthetic resin containers are currently in circulation. In the logistics industry that uses prefabricated synthetic resin containers, as described above, ISO packaging modules have been adopted as part of the rationalization of logistics, and standardization of plane dimensions has been promoted for transportation efficiency. .

  Therefore, attaching an IC tag to a side plate of a container cannot be attached to a container that is currently distributed, even if there is no problem with a newly manufactured container. If it cannot be attached to a container currently in circulation, neither the adoption of the ISO packaging module nor the standardization of the plane dimensions of the container can be advanced at a stretch.

  Moreover, it is inevitable that the assembly-type synthetic resin container is damaged in the distribution process. In order to recycle damaged containers, it is necessary to remove the IC tag. The container can only be crushed after the IC tag is removed. Therefore, when recycling, it is preferable that the IC tag can be easily removed from the collected container.

  Further, when the assembly type synthetic resin container is loaded on the pallet, it is often arranged as shown in FIG. That is, when the containers Y are stacked in parallel with the pallet P, one of the side plates on the short side that is folded first is directed outward and does not contact the adjacent containers. In the case of a side plate on the long side, it may be sandwiched between containers on both sides when loaded on a pallet and may not be directed outward.

  In addition, when the IC tag is attached to the side plate on the long side, it is located inside as described above when loaded on the pallet, and there is a risk that moisture such as vegetables and fruits may be interposed between the IC tag and the antenna. Yes, it may be difficult to read the record.

  The present invention has been made in view of the present situation, and a side plate is disposed on a flat rectangular bottom plate via a bent portion or a rotation shaft, and can be easily folded by operating a lock lever. The purpose of the present invention is to provide an assembly type synthetic resin container equipped with a lock lever that can be easily attached to a currently distributed container. And Also, it is possible to provide an assembly type synthetic resin container that can prevent the reading of the IC tag from being difficult due to moisture or the like even when containers storing vegetables, fruits, etc. are loaded in parallel on a pallet. Objective.

  Further, the side plates 4 and 4 on the long side facing the short side plates 3 and 3 facing each other are provided with a lock portion 13 so that the side plates 3 and 3 on the short side do not fall inward when assembled. Is provided. The lock portion 13 is formed at both ends of an engagement projection 15 projecting from the inner surfaces of the pair of long side plates 4 and 4 and the lock lever 16 disposed on the pair of short side plates 3 and 3. The engagement piece 17 is configured. The lock lever 16 is disposed on the upper side of the side plates 3 and 3 on the short side.

  The engaging protrusions 15 constituting the lock portion 13 protrude from the inner surfaces of the side plates 4 and 4 on the long side and are formed in a substantially rectangular shape in the plane, but the lower surface is inclined or curved in the front. To form a substantially triangular shape.

  Accordingly, the engagement protrusion 15 gradually increases toward the end edge of the side plate, and the engagement surfaces with the engagement pieces 17 formed at both ends of the lock lever 16 are formed as vertical surfaces. The engagement protrusion 15 is cut out at three sides except for the root portion. In other words, the upper and lower sides of the engaging protrusion 15 and the three sides near the edge of the side plate 4 are cut out in a substantially U shape, and are formed to be deformable up and down.

  On the other hand, the lock lever 16 is disposed so as to be movable up and down in a recess 18 provided on the upper outer surface of the pair of opposing side plates 3 and 3 on the short side. Engagement pieces 17 that engage with the engagement protrusions 15 are provided horizontally at both ends of the operation part 20 of the lock lever 16 in the longitudinal direction, and a finger-engaging recess 22 is formed on the outer surface of the central part. Are provided with springs 23 and 23 for urging the operation unit 20 upward.

  When the lock lever 16 is abutted against the concave portion 18 of the side plates 3, 3, the locking rod 28 comes into contact with the protruding piece 27 a of the hook-shaped protrusion 27. When both are pressed as they are, the hook-shaped protrusion 27 and the locking rod 28 are slightly deformed, the locking rod 28 is positioned on the back side of the protruding piece 27a, and the hook-shaped protruding piece 27a is inserted into the gap 28a. . The locking rod 28 is locked to the hook-shaped protrusion 27 to prevent the locking rod 28 from coming off, and is also slidably locked in the vertical direction of the side plates 3 and 3.

  In this way, the lock lever 16 is mounted on the concave portion 18 provided on the upper outer surface of the side plates 3 and 3 on the short side so as to be movable up and down against the springs 23 and 23. The invention is not limited to the embodiment. The hook-shaped protrusion 27 and the locking bar 28 can be omitted, and can be appropriately changed to another locking structure.

  Next, a structure for attaching the IC tag to the lock lever 16 which is a feature of the present invention will be described. 6 to 8 show an embodiment in the case where the IC tag is attached to the front surface side of the lock lever 16. An IC tag recess 30 for attaching the IC tag is formed on the left side of the finger hook recess 22 of the lock lever 16. The concave portion 30 for the IC tag is formed by recessing the surface of the operation portion 20 of the lock lever 16 and projecting a claw 31 for locking the IC tag on the upper and lower surfaces. The IC tag is inserted and attached between the vertical surface of the IC tag recess 30 and the claw 31.

  The size of the IC tag recess 30 may be determined according to the size of the IC tag. Further, the depth (depth) of the IC tag recess 30 is formed within the thickness dimension of the lock lever 16 so that the IC tag to be attached does not protrude from the surface of the lock lever 16. The vertical surface of the concave portion 30 for the IC tag can be a lattice-like surface instead of a plate-like smooth surface. The IC tag recess 30 is not limited to the left side of the finger hook recess 22 and may be formed on either the left or right side.

  The claw 31 in the IC tag recess 30 can be omitted. When the claw 31 is omitted, the IC tag may be attached using an adhesive or an adhesive, or may be directly embedded by in-mold molding. Furthermore, the IC tag is pressed against the IC tag recess 30 of the lock lever 16 to give a fine ultrasonic vibration to the lock lever 16 and at the same time, the IC tag is melted instantaneously by pressurizing and joined by an ultrasonic welding method. It may be welded.

  9 and 11 show a second embodiment showing an IC tag mounting structure. In this embodiment, an IC tag is attached to the back side of the lock lever 16. That is, the IC tag recess 30A for attaching the IC tag is formed on the back surface on either the left or right side of the finger hanging recess 22 of the lock lever 16. The IC tag recess 30A may be formed by recessing the back surface of the front plate 16c in the same manner as the IC tag recess 30. However, the IC tag recess 30A may be formed between the upper plate 16a and the lower plate 16b forming the lock lever 16. You may form by providing the tag attachment board 16d.

  The shape of the IC tag recess 30A can also be formed in the same manner as the IC tag recess 30. In addition to a structure in which a claw is provided and locked, it may be a method of adhesion or sticking, or may be attached by in-mold molding. Alternatively, welding may be performed by an ultrasonic welding method. Further, the shape can be appropriately changed depending on the type of IC tag to be attached.

  There are several methods for reading an IC tag. For example, there are a batch reading method that reads a plurality of containers in a state of being loaded on a pallet, and an individual reading method that reads each container. There are a method of reading on the line of the conveyor and a method of reading with a handy device offline. In the method in which the handy device is used individually, it is necessary to bring the handy device close to the IC tag, so it is preferable that the attachment position of the IC tag can be confirmed.

  Therefore, when forming the IC tag recess 30 </ b> A, it is preferable to provide a tag position mark 32 indicating the position of the IC tag on the corresponding surface side of the lock lever 16. In the embodiment shown in FIG. 9, grid-like ribs 32a are provided as tag position marks 32 on the surface side corresponding to the IC tag recess 30A. As described above, when the tag position mark 32 is formed by the lattice-like ribs 32 a, the tag position mark 32 functions not only as a tag position mark but also as a reinforcement of the lock lever 16.

  The tag position mark 32 is a mark that indicates which side of the finger-hanging concave portion 22 is seen from the surface side when the attached IC tag is viewed from the front side. Therefore, the tag position mark 32 is not limited to the grid-like rib 32a as described above. One or more ribs may be used, and one small recess or protrusion may be used.

  FIG. 12 and subsequent figures show an attachment structure for preventing the IC tag from being detached from the recess of the lock lever. 12 and 13 show a locking structure between the notch provided in the IC tag and the protrusion provided on the side surface of the recess 30. FIG. The lock lever 16 is provided with an IC tag recess 30B, and the upper plate 16a is provided with a slit 33 penetrating the IC tag recess 30B.

  On the side surface 34 of the concave portion 30B for the IC tag, an inward projection 35a is projected from a substantially middle portion in the height direction. The upper surface of the protrusion 35a is inclined inward and downward so that the IC tag 40 can be easily inserted. On the other hand, a step portion 41 is formed on the side surface of the IC tag 40 so as to be engaged with the projection 35a at an intermediate portion.

  Therefore, when the IC tag 40 is inserted from the slit 33, it comes into contact with the protrusion 35a. However, when the IC tag 40 is further pushed in, the IC tag 40 is pushed in while being slightly deformed, and the protrusion 35a and the step portion 41 are locked. As described above, the protrusion 35a and the stepped portion 41 are locked, and the upper end portion of the IC tag 40 is locked by a part of the upper plate 16a and the front plate 16c, thereby preventing detachment.

  FIG. 13 is a front view showing a state where the IC tag is locked in the IC tag recess. FIG. 13A is a front view of FIG. 13 (b) is provided with a notch 42 on the side surface of the IC tag 40b, and a protrusion 35b that fits into the notch 42 is provided on the side surface of the IC tag recess 30B. FIG. 13 (c) A cutout 43 is provided at the upper end corner of the IC tag 40c, and a protrusion 35c for locking the cutout 43 is provided at the upper end of the side surface of the IC tag recess 30B.

  In FIG. 13 (b), when the IC tag 40b is inserted from the slit 33, the IC tag 40b comes into contact with the projection 35b. Is prevented. In FIG. 13C, when the IC tag 40c is inserted from the slit 33, when the IC tag 40c is further pressed down after contacting the protrusion 35c, the protrusion 35c is locked to the notch 43 of the IC tag 40c, thereby preventing upward slipping. Is done. Further, the upper end portions of the IC tags 40b and 40c are locked to a part of the upper plate 16a and the front plate 16c, thereby preventing the IC tags 40b and 40c from coming off from the IC tag recess 30B.

  FIG. 14 shows an attempt to prevent the protrusion 44 provided on the side surface of the IC tag 40d from being pushed upward by press-fitting the protrusion 44 into the IC tag recess 30C. That is, a protrusion 44 protruding in an arc shape is provided on the side surface of the upper end portion of the IC tag 40d. In the illustrated embodiment, the protrusion 40d is formed in an arc shape, but may be formed in a square shape, or may be divided into two stages.

  When the length dimension of the slit 33 is L1, the length dimension of the IC card 40d is L2, and the length dimension of the protruding portion 44 is L3, the respective relations are L1> L2 and L1 <L3. Therefore, when the IC tag 40d is inserted into the slit 33, the protrusion 44 protruding from the upper end of the IC tag 40d comes into contact. When the IC tag 40d is further pushed in, the protrusion 44 descends while rubbing the side surface of the IC tag recess 30C.

  Since the protrusion 44 of the IC tag 40d presses the side surface of the IC tag recess 30C, it is prevented from coming off. The protrusion 44 is not limited to the upper end of the IC tag 40d, but may be a lower end portion or an intermediate portion.

  15 and 16 show another mounting structure of the IC tag 40e, and the IC tag 40e is mounted from the front of the IC tag recess 30D as in the embodiment shown in FIG. That is, a through hole 45 is formed at an appropriate location of the IC tag 40e, and a locking projection 36 fitted into the through hole 45 is provided in the IC tag recess 30D.

  The locking protrusion 36 is preferably formed so that the tip is hooked so as to lock the IC tag 40e. For example, the locking protrusion 36 is formed on a mushroom umbrella-shaped protrusion 36a as shown in FIG. Alternatively, it is preferable to form the hook-shaped protrusion 36b as shown in FIG. Although the two through holes 45 and the locking projections 36 are provided in the illustrated embodiment, the number of the through holes 45 and the locking protrusions 36 may be one or more, and may be appropriately determined depending on the size and shape of the IC tag.

  In the embodiment shown in FIGS. 12 to 16, the IC tag recess is provided on the front surface side of the lock lever. However, as in FIGS. 7 to 11, the same configuration can be provided on the back surface side of the lock lever. It is. When the IC tag recess is provided on the back side of the lock lever, it may be formed symmetrically with the configuration on the front side.

  In the present invention, the IC tag is attached to the lock lever in view of the fact that the lock lever is commonly used even in the assembly type synthetic resin containers having the same planar shape and different heights. Therefore, it can be applied to newly manufactured containers as well as many existing containers by simply replacing the lock lever. The ISO packaging module adopted in recent years and the common use of containers by the industry (Standardization) can also be supported.

  Further, when the container is damaged or when it is recycled, the IC tag must be removed. However, by attaching the IC tag to the lock lever, it is easier to remove the IC tag than when attaching to the container body.
