Abstract

PROBLEM TO BE SOLVED: To provide an individual packaging case easily taken out of a master case, with excellent strength, sealability and a simple structure.SOLUTION: When a lid plate 2 is pulled upward by inserting a finger into a finger hooking hole 8 for opening and closing, an inserting piece 3 continued to the lid plate 2 is also pulled upward. As a result, an engaging position of narrow parts 5b of a lid plate fixing piece 5 in relation to a slit 9 moves to a guide part 9b from insertion parts 9a, and further moves to a lower end of the guide part 9b along the guide part 9b. Thus, since the lid plate 2 is held in a state opened by a given angle at the engaged position of the lower end of the guide part 9b with the narrow part 5b of the lid plate fixing piece 5, the individual packaging case 100 contained in the master case 101 can be easily taken out by hooking the fingers to finger hooking holes 10 formed on both ends of the lid plate 2.

Description

  The present invention relates to a packaging case for packaging products and the like, and more particularly to a packaging case for individual packaging in which a plurality of large cases are packaged.

  Conventionally, when packing and shipping small-sized electric products, precision equipment bodies, or replacement items such as replacement parts, a packaging case (hereinafter referred to as an individual packaging case) in which the packed item is individually packaged is referred to as a large outer case ( A plurality of items are stored in a master case and shipped. At this time, in order to prevent rattling of the individual case in the master case during transportation, and to increase transport efficiency and loading efficiency during storage, the individual case is usually stored in a line without any gaps in the master case. is doing.

  However, when unpacking the master case and taking out the individual case, if the individual case is stored without any gaps, the first one box (or the first one in each stage when multiple stages are loaded) There is no part to put your fingers on when removing the battery, which reduces workability when unpacking, and damages the individual case or unintentional load on your fingers. .

  Therefore, various individual packaging cases with improved removal from the master case have been proposed. For example, in Patent Document 1, the left and right corner portions located on the upper surface side of the box are spread over two surfaces connected to the corner portions. There is disclosed a packaging inner box in which two parallel score lines are provided and a finger insertion portion is formed by pushing a portion between the score lines inward.

  Patent Document 2 discloses a cut-and-raised portion surrounded by a U-shaped perforation continuous with a ridge line on both sides of an upper surface flap of an individual carton, and a handle portion made of a punched hole inside the cut-and-raised portion. The structure provided with the handle part which has is disclosed. Further, Patent Document 3 discloses a configuration in which a part of the inner flap is cut off to form a pickup member, and a notch for inserting the pickup member into the top plate is provided.

  However, the method of Patent Document 1 has a problem that the strength of the corner portion is lowered because the corner portion is cut. Further, the method of Patent Document 2 has a problem in that after the perforation is broken and the handle portion is formed, a hole is formed in the upper surface flap, which cannot be reused as an individual case. On the other hand, in the method of Patent Document 3, it is necessary to insert the pickup member into the notch of the top plate at the time of packing, and the packing work becomes complicated and the appearance of the individual packaging case also deteriorates.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide an individual case with a simple configuration that can be easily taken out from a master case and is excellent in strength and airtightness.

  In order to achieve the above object, the present invention is formed by folding a box having at least one open surface, an openable / closable cover plate extending on one side of the opening edge of the box, and an end of the cover plate being bent. And an insertion piece that holds the lid plate in a closed state by being inserted into the opening edge, and a lid plate fixing that is provided on a side surface of the box that overlaps the insertion piece and is inserted into a slit formed in the insertion piece In the individual case having a piece, the lid plate fixing piece has a wide portion inserted into the slit, and a narrow portion formed at a base end portion of the wide portion, the slit being The insertion portion has substantially the same width as the wide portion, and the guide portion has substantially the same width as the narrow portion formed continuously below the insertion portion.

  Further, the present invention is characterized in that, in the individual packaging case having the above-described configuration, a gripping finger hooking hole is formed at both ends of the lid plate in a direction parallel to a fold line when the lid is opened and closed. .

  Further, according to the present invention, in the individual packaging case having the above-described configuration, a mountain fold line substantially parallel to a fold line when the lid body is opened and closed is formed on the outer surface of the lid plate so as to connect the gripping finger hook holes. It is characterized by being.

  According to the first configuration of the present invention, the narrow part of the lid plate fixing piece is the slit guide part by pulling the lid plate with the wide part of the lid plate fixing piece inserted into the slit insertion part. Since the lid is engaged with the lower end and the lid plate is held at a predetermined angle, the first one of the individual cases accommodated in the master case in an aligned state with a finger inserted between the box and the lid plate. The box can be easily removed.

  Further, according to the second configuration of the present invention, in the individual packaging case of the first configuration described above, a gripping finger hooking hole is formed at both ends of the lid plate in a direction parallel to the folding line when the lid is opened and closed. Thus, the individual case accommodated in the master case in an aligned state can be easily lifted by placing a finger on the gripping finger hanging hole.

  Further, according to the third configuration of the present invention, in the individual case of the second configuration described above, it is substantially the same as a fold line when opening and closing the lid so that the gripping finger hooking hole is connected to the outer surface of the lid plate. By forming parallel mountain fold lines, when the individual case is lifted by placing a finger on the gripping finger hanging hole, the cover plate is bent into a mountain shape along the mountain fold line. Since the bent portion serves as a beam, there is no possibility that the edge of the cover plate is bent or the connecting portion with the box is broken even if the individual case is a long and narrow box.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a configuration example of an individual case of the present invention. The individual case 100 includes a box body 1 having an open upper surface, a cover plate 2 extending on one side of the opening end of the box body 1, and an insertion piece 3 formed by bending one end of the cover plate 2. When the cover plate 2 is closed, the cover plate 2 can be held in a closed state by inserting the insertion piece 3 into the opening 4 of the box 1.

  The box 1 is provided with a lid plate fixing piece 5 for locking the lid plate 2, and for lifting the lid plate 2 on the lid plate 2 side across the boundary between the lid plate 2 and the insertion piece 3. A substantially rectangular finger-opening hole 8 for opening and closing is formed, and a slit 9 into which the cover plate fixing piece 5 is inserted is formed on the insertion piece 3 side. Also, semicircular gripping finger-holding holes 10 are provided at both end edges in the longitudinal direction of the lid plate 2 (direction parallel to the folding line at the boundary between the box 1 and the lid plate 2). A mountain fold line 11 that is substantially parallel to the fold line at the boundary between the box 1 and the cover plate 2 is formed on the outer surface so as to connect the gripping finger-holding holes 10.

  2 is a partially enlarged view of the vicinity of the slit 9 in FIG. 1, and FIG. 3 is a partially enlarged view of the vicinity of the cover plate fixing piece 5 in FIG. As shown in FIG. 2, the slit 9 has an insertion portion 9a into which the cover plate fixing piece 5 is inserted, and a guide portion 9b continuous below the insertion portion 9a. As shown in FIG. 3, the cover plate fixing piece 5 can be bent into an L shape by a fold line 13, and a portion from the fold line 13 to the tip is a wide portion 5a to be inserted into the insertion portion 9a. A narrow portion 5b is formed at the base end portion of the wide portion 5a so as to straddle the folding line 13.

  The length L1 of the insertion portion 9a is formed substantially the same as the width W1 of the wide portion 5a so that the wide portion 5a can be inserted. Further, the length L2 of the guide portion 9b is formed substantially the same as the width W2 of the narrow portion 5b.

  FIG. 4 is a front view of the individual packaging case showing the state in which the cover plate 2 is closed. For convenience of explanation, the cover plate fixing piece 5 is hatched in FIG. 4 and FIGS. 5 and 6 described later. By inserting the wide portion 5 a of the lid plate fixing piece 5 into the insertion portion 9 a of the slit 9, the lid plate 2 is held in a closed state.

  5 is a front view showing a state in which the cover plate 2 is pulled up from the state of FIG. 4, and FIG. 6 is a partial cross-sectional view of the vicinity of the cover plate fixing piece 5 in FIG. ). When a finger is inserted into the opening / closing finger-hanging hole 8 and the cover plate 2 is lifted upward, the insertion piece 3 connected to the cover plate 2 is also lifted upward. As a result, the engagement position of the narrow portion 5b of the lid plate fixing piece 5 with respect to the slit 9 moves from the insertion portion 9a to the guide portion 9b, and further moves along the guide portion 9b to the lower end portion of the guide portion 9b. That is, the lid plate 2 can be moved up and down by the amount of the guide portion 9b. As shown in FIGS. 5 and 6, the lid plate 2 has a narrow width between the lower end portion of the guide portion 9b and the lid plate fixing piece 5. It is held in a state where it is opened by a predetermined angle at a position where the portion 5b is engaged.

  FIG. 7 is a perspective view showing a state in which the first one box is taken out from a plurality (three in this case) of individual cases housed in alignment with the master case. As shown in FIG. 5 and FIG. 6, after inserting the finger into the opening / closing finger-hanging hole 8 and lifting the cover plate 2 and holding it in a half-open state, as shown in FIG. The individual case 100 is lifted by placing a finger on the gripping finger-holding hole 10. Thereby, the individual packaging case 100 accommodated in the master case 101 without a gap can be easily taken out.

  And when taking out a to-be-packaged item from the inside of the individual case 100, the cover plate fixing piece 5 is pulled out from the insertion portion 9a of the slit 9 with the cover plate 2 completely closed as shown in FIG. When the cover plate 2 is pulled up by placing a finger on the cover 8, the opening 4 of the box 1 is widely opened as shown in FIG. 1, and the packaged item can be taken out.

  Further, since the cover plate 2 is formed with a mountain fold line 11 along the longitudinal direction so as to connect the finger-holding holes 10 for gripping, the cover plate 2 is mounted on the cover plate 2 when the load when the individual packaging case 100 is taken out is large. It bends in a mountain shape along the fold line 11. Since the bent portion serves as a beam, even if the individual packaging case 100 is an elongated box, the longitudinal edge of the lid plate 2 is bent, or the connecting portion between the box 1 and the lid plate 2 is broken. The individual packaging case 100 can be smoothly taken out without doing so.

  The opening angle when the lid plate 2 is lifted is not particularly limited, but if the opening angle is too small, it is difficult to insert a finger into the gripping finger-holding hole 10, and if the opening angle is too large, the lid plate 2 is difficult to lift. Become. Therefore, an angle at which the finger can be smoothly inserted into the gripping finger hanging hole 10 is preferable.

  In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, various assembly methods such as a B-type that forms a bottom surface by engaging a pair of bottom plates and a pair of bottom flaps, and an A-type type that bends side plates connected to four sides of a rectangular bottom plate upward. Applicable to individual cases.

  The present invention can be used for individual cases that are accommodated in a master case in an aligned state. By using the present invention, it is possible to provide an individual case with a simple structure that can be easily taken out from the master case and is excellent in strength and airtightness.
