Description

  The present invention relates to a fixture for fixing a folded lid such as a cardboard box to a state in which it is temporarily opened and pushed down.

  Paper boxes such as cardboard boxes are often used for storage and shipping. Usually, a cardboard box is assembled by folding a piece of cardboard paper. FIG. 8 is a view showing the cardboard box (20), and shows the state in which the four folding lids (22a), (22b), (22c), and (22d) are opened. In this state, the upper part of the storage part (21) is opened, and luggage and the like can be taken in and out of the storage part (21).

  However, since each folding lid (22a), (22b), (22c), (22d) is connected to the storage part (21), it is pulled by the storage part (21) even when opened, as shown in FIG. As shown in FIG. That is, even if each folding lid (22a), (22b), (22c), (22d) is bent downward so as to come into contact with the side surface of the storage portion (21), the folding lids (22a), (22b), (22c) and (22d) are pulled upward at the bent portion (23) which is the boundary between the storage portion (21) and spread in the horizontal direction.

  Then, the cardboard box (20) occupies more space than necessary because of the folding lids (22a), (22b), (22c), and (22d) spreading in the lateral direction. In addition, the folding lids (22a), (22b), (22c), and (22d) may get in the way when an object is taken in and out of the cardboard box (20).

  In particular, when an operation is performed such that a plurality of cardboard boxes (20) are arranged side by side and a baggage is put in, the folding lids of adjacent boxes may interfere with each other and the operation may be difficult. In addition, the folding lid may come into contact with the worker, and the worker may fall and be injured.

  Furthermore, when picking or shipping work using a belt conveyor, etc., the folded lids (22a), (22b), (22c), (22d) deployed in the horizontal direction are part of the belt conveyor or around it. It may interfere with the desk, inspection equipment, picking worker, etc. placed on the desk, which may hinder smooth work.

  Therefore, a large rubber band has been applied to the opened folding lids (22a), (22b), (22c), and (22d), or temporarily stopped with an adhesive tape. However, since this is inconvenient, a fixing tool for fixing the folding lids (22a), (22b), (22c), and (22d) in a state in which the folding lids are completely folded downward has been demanded.

  In order to satisfy such demands, the inventions disclosed in Japanese Patent Application Laid-Open Nos. 9-189305, 2002-96816, and 44-2546 have been proposed.

  Each of the fixtures shown in these publications has an “inverted U shape” in cross section, and has an “opening” below. In use, the folding lid (22a), (22b), (22c), (22d) is folded and completely pushed down to the outside, and the folding portion (23), that is, the folding lid (22a ), (22b), (22c), (22d) and the storage part (21), and the folding lids (22a), (22b), (22c), (22d) are temporarily Secure to.

  The width of the opening below the fixture is approximately twice the total thickness of the storage portion (21) of the cardboard box (20) and the thickness of the folding lid, that is, the thickness of the cardboard box. If the width of the opening is narrower than twice the thickness of the cardboard, the fixture cannot be attached to the folded portion (23). On the other hand, if it is more than twice, play occurs and the folding lid cannot be held in a fully depressed state.

  However, there are various thicknesses of cardboard boxes, and conventional fixtures cannot be mounted on thick cardboard boxes. On the other hand, when it is used for a cardboard box with a small thickness, play cannot be pinched so that the folding lid cannot be kept completely pressed down.

  The folding lid is pulled by the bent portion (23) and tends to spread in the lateral direction, but the conventional fixture is attached so as to sandwich the bent portion (23). A big force will be added. Therefore, when it is used repeatedly, the fixing tool may be deformed by the force of the folding lid to spread sideways, and if it is made of resin, it may be broken.

For this reason, the fixture needs to be strong enough to oppose a strong force, but in order to obtain sufficient strength, it is necessary to use a thick and heavy metal plate, which is not preferable in terms of cost and productivity.

It is possible to provide a box lid fixing tool which can be easily manufactured by pressing the folding lid firmly against such a force.

  The present invention will be described below with reference to preferred embodiments.

  FIG. 1 is a view showing a box lid fixture (1) of this embodiment. In the figure, reference numerals (2a) and (2b) denote lid pressing portions that hold down the bent folding lid. In the present embodiment, a rectangular metal plate is bent approximately 90 ° into an L shape, so that the lid pressing portion (2a) as the first pressing portion and the lid pressing portion as the second pressing portion. (2b) was formed.

  The corners of the lid pressing portions (2a) and (2b) may be rounded so as not to be injured. Further, in this embodiment, a simple shape using a rectangular metal is used, but other shapes can be used as long as the lid pressing portion (2a) and the lid pressing portion (2b) opened approximately 90 ° can be formed. good. For example, each lid pressing portion may be oval and shaped like a butterfly wing as a whole.

  In the figure, (3) is a hook portion for hooking on the cardboard box, and its lower end is attached to the mountain side of the boundary between the lid pressing portion (2a) and the lid pressing portion (2b). At that time, the tip portion (3a) of the hook portion (3) is fixed so as to face the valley side of the boundary between the lid pressing portion (2a) and the lid pressing portion (2b). Although welding is used as the fixing means, other fixing means such as adhesion or “caulking” may be used for fixing.

  FIG. 3 is a view of the hook portion (3) as seen from the lateral direction. The hook part (3) is the hook inner part (3b) from the upper end part (3d) to the tip (3a), and the hook outer part from the upper end (3d) to the connection part of the lid pressing parts (2a) and (2b) (3c). During use, the hook inner part (2b) is inserted inside the cardboard box (20), and the hook outer part (3c) is exposed outside the cardboard box (20).

  The distance between the hook inner part (3b) and the hook outer part (3c) is wider at the lower distance (d2) than at the upper distance (d1). Therefore, the hook portion (3) can also be hooked on cardboard boxes having different thicknesses. Also, depending on the size of the upper distance (d1), the corner of the box may be bitten between the hook inner part (3b) and the hook outer part (3c) when installed, and the hook inner part (3b) and the hook outer part The corner of the box can also be sandwiched by the part (3c).

  The tip portion (3a) of the hook portion (3) has a shape that is slightly raised upward so that it can be easily inserted when mounted on the cardboard box.

  In this embodiment, the hook portion (3) is manufactured by using a double metal wire bent at the tip portion (3a), but this is for obtaining sufficient strength even with a thin metal wire. If a metal wire having sufficient strength is used, the metal wire may be used without being doubled like the hook portion (13) shown in FIG.

  In this embodiment, the lid pressing parts (2a), (2b) and the hook part (3) are made of metal in consideration of the strength. However, if the strength to withstand use can be secured, a material such as a synthetic resin can be used. You may make using.

  FIG. 2 is a diagram showing a use state of the present embodiment. With the folding lid of the cardboard box (20) opened and pushed down, the box lid fixing tool (1) is attached. At the time of mounting, the hook portion (3) is hooked on the corner of the cardboard box (20) so that the tip (3a) is inside the cardboard box (20).

  Then, the lid pressing portion (2a) attached to the outer lower end of the hook portion (3) presses the folding lid (22a), the lid pressing portion (2b) presses the folding lid (22b), and the folding lid ( The state where 22a) and (22b) are pushed down can be maintained. That is, two adjacent folding lids (22a) and (22b) can be fixed by one box lid fixing tool (1).

  Since two folding lids can be fixed with one box lid fixing tool (1) pushed down, if two are used, all four folding lids (22a), (22b), (22c ), (22d) can be held down.只 If the box is quite large, the side where the folding lid is not fixed may be lifted. In such a case, use four box lid fixing tools (1) and attach them to each corner. May be.

  Like the conventional fixture, the folding part (23) of the cardboard box (20), that is, the vicinity of the boundary between the folding lid (22a), (22b), (22c), (22d) and the storage part (21) The lid pressing portions (2a) and (2b) are pressed below the bent portion (23) rather than being pressed so as to be sandwiched.

  For this reason, the box lid fixture (1) takes very little force compared to the conventional fixture. Therefore, it is not necessary to increase the strength more than necessary, and a light box lid fixing tool can be obtained, and the manufacture is facilitated.

  When closing the folding lid (22a), (22b), (22c), (22d), remove the box lid fixing tool (1) from the cardboard box (20) by pulling it upward, and then The lids (22a), (22b), (22c), and (22d) may be closed.

  When not in use, the box cover fixture (1) should be put away in a standing state as shown in FIG. In that case, it is also possible to place a plurality of box lid fixtures (1) so as to overlap each other.

  The basic configuration of the present embodiment is the same as that of the first embodiment, except that the plate can be held. FIG. 5 is a view showing a plate (10) attaching portion in the present embodiment. On the plate (10), the type of items stored in the box, the delivery destination, the person in charge, the delivery time zone, etc. may be appropriately displayed as required by the operator.

  The lid pressing part (2b) is provided with two guide rails (11) for inserting the plate (10) and a plate stopper (12) for supporting the plate (10) so as not to fall down. . In this example, all of the plate (10), guide rail (11), and plate stopper member (12) were made of synthetic resin and adhered to the lid pressing portion (2b).

  Since the plate (10) is detachable, a plurality of plates displaying different information are prepared, and an appropriate plate can be attached and displayed as necessary. In this embodiment, the plate can be held only by the lid pressing portion (2b) on one side, but the plate may be held also on the other lid pressing portion (2a) if necessary.

  In addition to the structure using the guide rail (11) as described above as a structure for holding the plate (10), a pocket-like portion may be provided to hold the end of the plate (10). Attaching fasteners such as hook-and-loop fasteners, snaps, and magnets to the plate (10) and the lid pressing part (2b), and by locking both locking elements, the plate (10) is attached to the lid pressing part (2b). It may be attached.

  In this embodiment, the configuration of the first embodiment is further simplified. In Example 1, the lid pressing part was produced by bending a metal plate, the hook part (3) was produced by bending a metal wire, and both were joined by welding.

  FIG. 6 is a view showing the box lid fixture (14) of the present embodiment. In the present embodiment, the lid pressing portions (14a) and (14b) on both sides and the hook portion (14c) are formed by bending one metal wire. The hook portion (14c) is adjacent to the metal wire. However, if necessary, the hook portion (14c) may be partially fixed by welding, bonding or the like to increase the strength.

  As compared with the case of Example 1, the lid pressing portions (14a) and (14b) are thinner, so that the strength is reduced. For this reason, it is desirable to use a metal wire having a high strength, for example, a metal wire made of a thick metal wire or a strong metal.

  In addition, as shown in FIG. 7, you may make it increase the intensity | strength of a cover press part by bending the tip (14d) of a cover press part. In this way, it is possible to prevent the tip (14d) of the metal wire from being caught by the box or the operator. The bending method may be determined as appropriate in consideration of the design and strength, such as a frame shape or a spiral shape.

  Although the embodiment has been described by taking a cardboard box as an example, it can also be used for a box with a lid other than the cardboard box, such as a decorative box.

  In addition, although the box lid fixture which can display using a plate was shown as Example 2, as a means to display using the box lid fixture of this invention, methods other than a plate are also considered. . For example, a thin tube may be provided in the hook portion or the lid pressing portion, and the shaft portion of the flag-shaped display member may be inserted and held in the thin tube. Further, a clip for sandwiching the memo may be provided on the lid pressing portion, and if iron or nickel is used as the material of the lid pressing portion, the memo can be stopped on the lid pressing portion using a magnet.
