Description

  The present invention relates to a tray for storing or arranging articles.

  The tray includes holding walls having continuous outer wall portions, upper wall portions, and inner wall portions at both ends of the bottom wall. Each holding wall is formed with an insertion groove for arranging a partition wall or an article. By inserting both ends of the partition wall into the insertion groove of each holding wall, a space for accommodating the article is defined. Further, the article is installed while being laid by inserting both ends (for example, protruding portions) of the article into the insertion grooves of the respective holding walls.

  In the tray of Patent Document 1, a first insertion groove is provided in the inner wall portion of the first holding wall, and a second insertion groove extending from the inner wall portion to the upper wall portion is provided in the second holding wall. In this tray, the article is installed over both holding walls by inserting the second protrusion into the second insertion groove from above with the first protrusion of the article inserted into the first insertion groove.

  In the tray of Patent Document 2, insertion grooves extending from the inner wall portion to the upper wall portion are provided in both holding walls. In this tray, articles are installed over both holding walls by inserting each protrusion of the articles into the insertion grooves of the first and second holding walls from above. In addition, the tray which arrange | positions a partition wall instead of articles | goods forms an insertion groove similarly to this patent document 2. FIG.

  In each tray, a force to return to a flat state before assembly is applied to each holding wall by the waist (repulsive force) of the forming material. For this reason, the trays of Patent Documents 1 and 2 are provided with a fixing structure for maintaining the holding wall in the assembled state. In patent document 1, the adjacent frame wall is provided with the adjacent frame wall, and this frame wall and the holding wall are engaged. In patent document 2, the glue margin part is connected with the inner wall part, and the glue margin part is stuck on the bottom wall.

  However, since the tray of Patent Document 1 fixes the holding wall with the frame wall, the area of the blank is increased, the shape is complicated, and the cost is increased. Moreover, although the tray of patent document 2 can suppress the enlargement of a blank, since a complicated sticking operation | work increases, it is still high in cost. The same applies to a tray in which a partition wall is provided instead of an article.

  An object of the present invention is to provide a tray that can be easily and reliably assembled while suppressing an increase in the size of a blank.

In order to solve the above problems, the tray of the present invention has an outer wall portion bent upward with respect to the bottom wall at a position opposed to the bottom wall arranged to extend in the horizontal direction, and an inner wall with respect to the outer wall portion. In a tray provided with first and second holding walls having an upper wall portion bent in the direction and an inner wall portion bent downward with respect to the upper wall portion, the tray is provided on the inner wall portion, a first insertion groove in which the first protrusion is inserted, the first state of inserting the protruding portion into the first insertion groove, located above the front Symbol first protrusion, the first protrusion said There a regulating portion for preventing the withdrawal from the first plug groove, provided at a position facing the first insertion groove, extending toward the upper wall portion from said inner wall portion, a front Symbol first projecting portion while plugged into the first insertion groove, first the locating member located on the opposite side of the first projecting portion A second insertion groove into which the projecting portion is inserted from above, and the first insertion groove and the restricting portion are provided in the first holding wall, and the second insertion groove is provided in the second holding wall. A first disposition portion provided; and a second disposition portion provided with the first insertion groove and the restricting portion on the second holding wall and the second insertion groove provided on the first holding wall. In addition, a holding wall fixing disposition portion provided with the first insertion groove at a position opposite to the first and second holding walls is further provided. Or the said arrangement | positioning member is a partition wall which the said 1st and 2nd protrusion part is extended in both ends, and partitions off the articles | goods arrange | positioned on the said bottom wall. The tray is not limited to a usage pattern in which the bottom wall extends in the horizontal direction, but can be used in a mode in which the tray extends in the vertical direction. And if the attitude | position of a bottom wall is changed, the attitude | position (directionality) of each holding wall will also change.

  In addition, it is preferable that at least a part of the groove width of each insertion groove is substantially the same as the thickness of the protruding portion of the arrangement member. Further, the upper part of the first projecting portion of the arrangement member is an upper wall portion when the first insertion groove is formed to extend to the upper end of the inner wall portion, and the first insertion groove is the upper end of the inner wall portion. When it is formed so as not to extend to the upper part, it is the upper part of the inner wall part. Further, when the first and second holding walls are formed so that the respective insertion grooves extend to the lower end of the inner wall portion, the first and second holding walls are continuously provided with bottom overlapping portions that are bent outward with respect to the inner wall portion, When the insertion groove is not extended to the lower end of the inner wall portion, it is possible to realize a configuration in which the bottom overlapping portion is not provided continuously.

  In this tray, when the first and second protrusions of the arrangement member are inserted into the first and second insertion grooves, the upward movement of the first protrusion is restricted by the restriction portion, and the arrangement member is prevented from falling off. . Moreover, the holding | maintenance wall in which the 1st insertion groove was formed prevents the expansion | deployment effect | action by a repulsive force by insertion of a 1st protrusion part, and an assembly state is maintained. And since a tray is provided with the 1st arrangement part formed in the 1st holding wall and the 2nd arrangement part formed in the 2nd holding wall in the 1st insertion slot and a regulation part, it is provided in the position opposite to a bottom wall. Each holding wall can be reliably maintained in the assembled state.

  As described above, the tray of the present invention can be easily and reliably assembled only by arranging the arrangement member on the holding wall having the outer wall portion, the upper wall portion, and the inner wall portion. Therefore, since it is not necessary to provide a special structure for maintaining the holding wall in the assembled state, it is possible to suppress an increase in size of the blank and an increase in cost.

In the holding wall fixing arrangement portion, the arrangement member is first arranged on the holding wall fixing arrangement portion. Thereby, since each holding wall which opposes can be maintained in an assembly state reliably, the assembly workability | operativity of the arrangement | positioning member to another 1st and 2nd arrangement | positioning part can be improved.

  It is preferable that the first and second placement portions are alternately provided along the extending direction of the first and second holding walls. This configuration includes forming another third arrangement portion (for example, a holding wall fixing arrangement portion) in addition to the first and second arrangement portions. In this case, a configuration in which a third arrangement portion is formed instead of the first or second arrangement portion arranged alternately (first arrangement portion, second arrangement portion, first arrangement portion, third arrangement portion, first arrangement portion) , Second placement unit ...) and a configuration in which the third placement unit is inserted in between (first placement unit, second placement unit, first placement unit, third placement unit, second placement unit, first placement unit) …), Including both.

  The first insertion groove is provided so as to extend from the inner wall portion to the upper wall portion, and the restriction portion is provided on the upper wall portion so as to be positioned at a tip end of the first insertion groove. If it does in this way, the workability | operativity at the time of inserting the 1st protrusion part of an arrangement | positioning member in a 1st insertion groove can be improved. Moreover, it can prevent reliably that the 1st protrusion part of an arrangement | positioning member separates from a 1st insertion groove by the control part located in the front-end | tip of a 1st insertion groove.

  The tray of this invention can maintain the holding wall which has an outer wall part, an upper wall part, and an inner wall part in an assembly state simply and reliably only by inserting and arrange | positioning the protrusion part of an arrangement | positioning member in an insertion groove. Therefore, it is possible to prevent an increase in the size of the blank and an increase in cost.

Moreover, the thickness of each protrusion 56A, 56B is substantially the same as the groove width of each insertion groove 48, 50.

  The tray 20 configured in this manner is shipped to the manufacturer of the article 1 in the blank state shown in FIGS. And the partition wall 51 is arrange | positioned and assembled to the tray main body 21 at the time of use, and the articles | goods 1 are arrange | positioned in the divided arrangement | positioning space. The article 1 placed on the illustrated tray 20 is a glass tube product having a diameter of 30 mm and a weight of 350 g, for example.

  When assembling the tray 20, as shown in FIG. 2, the second holding wall 24 </ b> B on the left side is arranged in the order of the outer overlapping portion 38, the bottom overlapping portion 36, the inner wall portion 34, the upper wall portion 32 and the outer wall portion 25. Bend with. Thereafter, the first protruding portion 56A of the folded partition wall 51 is obliquely inserted from above into the first insertion groove 48 of the holding wall 24B constituting the holding wall fixing arrangement portion 45. At this time, the protruding portion 56A is inserted in a state where the first cutout portion 54 is positioned on the upper side and the second cutout portion 55 is positioned on the lower side.

  Next, the right first holding wall 24 </ b> A is bent in the order of the outer overlapping portion 38, the bottom overlapping portion 36, the inner wall portion 34, the upper wall portion 32, and the outer wall portion 25. Then, as shown in the figure, the partition wall 51 is inserted into the first insertion groove 48 constituting the holding wall fixing arrangement portion 45 of the holding wall 24A in a state where the holding wall 24A is inclined obliquely with respect to the bottom wall 22. The second protrusion 56B is inserted from above.

  Thereafter, the first holding wall 24A is moved along the folding line 27 while pressing the protruding portion 56B downward so that the second protruding portion 56B of the partition wall 51 is disposed in the first holding wall 24A. Bend it. Thereby, as shown in FIG. 3, the first partition wall 51 is arranged in the holding wall fixing arrangement portion 45 having the pair of first insertion grooves 48, 48. The first and second holding walls 24A and 24B may be bent in the reverse order.

  Here, the tray 20 on which the glass tube product having a diameter of 30 mm is arranged may have a total height of the holding walls 24 </ b> A and 24 </ b> B of 30 mm, and such a small frame wall opens to the outside due to the repulsive force of the corrugated paper 10. However, in the present embodiment, in a state where the partition wall 51 is arranged in the holding wall fixing arrangement portion 45, the protruding portions 56A and 56B are positioned along the overlapping portions 36 and 38 in the first insertion grooves 48 and 48. The restricting portion 49 is located at the upper end of the projecting portions 56A and 56B. Further, the notches 54 and 55 of the partition wall 51 are located at both ends of the first insertion groove 48. Therefore, the unfolding action of the pair of holding walls 24A and 24B due to the repulsive force of the corrugated paper 10 is prevented, and the assembled state is reliably maintained.

  Next, the partition walls 51 are arranged on all the first and second arrangement portions 46 and 47. That is, as shown in FIG. 4, the first protrusion 56A of the partition wall 51 is inserted into the first insertion groove 48 of the first holding wall 24A. In this state, the second projecting portion 56B located on the opposite side is inserted into the second insertion groove 50 of the second holding wall 24B from above (the first projecting portion 56A is rotated about the first projecting portion 56A). 1 placement section 46). Similarly, after the first protrusion 56A of the partition wall 51 is inserted into the first insertion groove 48 of the second holding wall 24B, the second protrusion 56B located on the opposite side is inserted into the first holding wall 24A. Is inserted into the second insertion groove 50 (second arrangement portion 47).

  As described above, the first and second arrangement portions 46 and 47 have the first insertion groove 48 that can lock the protruding portions 56A and 56B of the partition wall 51 as only one of the holding walls 24A and 24B, and the other from above. It is set as the 2nd insertion groove 50 which can be inserted. Therefore, it is possible to secure the locking performance while improving the assembly workability. In addition, since only one central part is a double-sided lock and the other is alternated by a single-sided lock, it can be locked with a good balance. Although the second insertion groove 50 is not provided with a special locking structure, the groove width is formed substantially the same as the wall thickness of the partition wall 51. The two protruding portions 56B are prevented from coming off.

  As shown in FIG. 1, the partition walls 51 are arranged in all the arrangement parts 45 to 47, and the article 1 is arranged in the partitioned arrangement space. Then, a plurality of trays 20 are stacked and accommodated in a well-known packaging box (not shown) and transported. At this time, since the tray 20 of the present embodiment is set so that the intermediate shin 13 extends in the vertical direction with respect to the wall portions 25, 34, 38, 51 extending in the vertical direction, a sufficient pressure resistance can be ensured. . In addition, since the holding walls 24A and 24B have the restricting portion 49 (continuous portion) remaining at the tip of the first insertion groove 48, a decrease in rigidity can be suppressed.

  As described above, in the tray 20 of the present invention, the movement of the partition wall 51 is restricted only by inserting the protrusions 56A and 56B of the partition wall 51 into the insertion grooves 48 and 50, and the partition wall 51 is separated from the tray body 21. Can be prevented from falling off. Further, the holding walls 24A and 24B in which the first insertion grooves 48 are formed are prevented from expanding due to the repulsive force due to the insertion of the protruding portions 56A, and the assembled state is maintained. Therefore, it can be assembled easily and reliably, and since it is not necessary to provide a special structure for fixing the holding walls 24A and 24B, it is possible to suppress an increase in size of the blank and an increase in cost.

  Moreover, in the present embodiment, since the first insertion groove 48 is provided as the holding wall fixing placement portion 45 provided at the position facing the holding walls 24A and 24B, the partition wall 51 is provided in the holding wall fixing placement portion 45. By arranging the first, it is possible to greatly improve the workability of placing the partition wall 51 on the first and second placement portions 46, 47. In addition, the first insertion groove 48 is provided so as to extend from the inner wall portion 34 to the upper wall portion 32, and the upper wall portion 32 positioned at the distal end portion of the first insertion groove 48 constitutes a restriction portion 49. . Therefore, it is possible to significantly improve the insertion workability of the protruding portion 56A into the first insertion groove 48 after reliably preventing the protrusion 56A from being detached from the first insertion groove 48.

  The tray 20 of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made.

  For example, the tray 20 is not limited to a usage pattern in which the bottom wall 22 is disposed so as to extend in the horizontal direction as shown in FIG. And if the attitude | position of the bottom wall 22 is changed, the attitude | position (directivity) of each holding wall 24A, 24B will also change. That is, in the present invention, in order to clarify the configuration of the bottom wall 22, the holding walls 24A and 24B, and the insertion grooves 48 and 50, the posture in which the bottom wall 22 is arranged to extend in the horizontal direction is used as a reference. Even the tray 20 with the bottom wall 22 extending in the vertical direction is included in the technical scope of the present invention.

  Moreover, in the said embodiment, although the partition wall 51 was arrange | positioned in the tray main body 21 and the space which arrange | positions the articles | goods 1 was defined, as shown in FIG. 7, the 1st and 2nd insertion grooves 48 and 50 are used for the articles | goods 1. As shown in FIG. It is good also as a structure arrange | positioned directly to a pair and hold | maintaining on a pair of holding wall 24A, 24B. As this article 1, for example, a roller having a rotating shaft protruding from both ends as protruding portions 56A and 56B can be cited. Further, in this modification, the holding wall fixing arrangement portion 45 including the pair of first insertion grooves 48 and 48 is not provided. Furthermore, the groove widths of the first and second insertion grooves 48 and 50 are formed to be substantially the same as the diameter of the rotating shaft. The tray 20 configured as described above can maintain the holding walls 24A and 24B in the assembled state in the same manner as described above by arranging the articles 1 in the first and second arrangement portions 46 and 47, respectively.

  Furthermore, in the said embodiment, although the 1st insertion groove 48 was formed so that it might extend from the inner wall part 34 to the upper wall part 32, you may provide so that only the inner wall part 34 may open. In this case, the 1st insertion groove 48 may be provided so that it may extend to the upper end of the inner wall part 34 in an assembly state, and may be provided so that it may not extend to an upper end. However, when it is formed so as not to extend to the upper end, the restricting portion 49 for preventing the first projecting portion 56A from being separated is constituted by the upper portion of the inner wall portion 34. Moreover, although the 1st and 2nd insertion grooves 48 and 50 were formed so that it might extend to the lower end of the inner wall part 34, you may form so that it may not extend to a lower end.
