In the present embodiment, the linear length L (see FIG. 4) from the tightening portion 113 to the shoulder portion 114 of the container 100 is about 10 to 15 mm. In addition, the container 100 used as the holding object in the container holder 1 of this invention is not limited to such an aspect.

  The container holder 1 according to the present embodiment can be formed by assembling the unfolded sheet shown in FIG. 1, and the unfolded sheet has a substantially rectangular shape.

  As shown in FIG.1 and FIG.2, the container holder 1 which concerns on this embodiment is the upper surface board 2, the bottom face board 3, and the edge of the short side of the bottom face board 3, respectively via the folding lines 4a and 5a. Folding pieces 4 and 5 connected to each other are provided, and the top plate 2 and the bottom plate 3 have an octagonal corner cut shape.

  The top surface plate 2 and the bottom surface plate 3 are connected via a single fold line 2a, and the top surface plate 2 is formed by folding the top surface plate 2 on the bottom surface plate 3 along the fold line 2a. 3 has a size that can cover substantially the whole.

  Each of the top surface plate 2 and the bottom surface plate 3 has two finger holes (finger fingers) that overlap the virtual line segments VL1 and VL2 connecting the centers of the short sides of the top surface plate 2 and the bottom surface plate 3 for inserting and lifting fingers. Differential holes) 25 and 35 are formed in parallel along the longitudinal direction of the top plate 2 and the bottom plate 3. The finger holes 25 of the top plate 2 and the finger holes 35 of the bottom plate 3 overlap each other when the top plate 2 is folded on the bottom plate 3 along the fold line 2a and the container holder 1 is assembled ( Formed to match). When the top plate 2 is folded over the bottom plate 3 along the fold line 2a, the top plate 2 (bottom plate 3) portion between the two finger holes 25, 25 (35, 35) is the container holder. The grip part when lifting 1 is comprised.

  Two substantially fold lines 21a and 22a are formed along the imaginary line segment VL1 of the upper surface plate 2 at approximately the center in the short-side direction of the upper surface plate 2, and the container holder 1 in which the unfolded sheets are assembled. In FIG. 2, the groove 27 along the longitudinal direction (lateral direction in FIG. 1) of the top plate 2 can be formed by folding along the two folding lines 21a and 22a (see FIG. 2). The two folding lines 21a and 22a are preferably parallel to each other, but may be formed in a range from parallel to ± 1 °.

  The two fold lines 21a and 22a for forming the groove portion 27 are formed so that the surface facing the bottom surface 28 of the groove portion 27 is formed on the bottom surface plate 3 when the top plate 2 is folded on the bottom plate 3 along the fold line 2a. It forms so that it may contact | abut (refer FIG. 3). And the part which the surface facing the bottom face 28 of the groove part 27 contact | abuts to the bottom face board 3 is comprised as an area | region (applicable adhesive application | coating area | region) which can apply | coat an adhesive agent, By applying an adhesive agent to the said area | region The surface facing the bottom surface 28 of the groove portion 27 of the top plate 2 and the bottom plate 3 can be bonded via an adhesive. In addition, there is no restriction | limiting in particular as an adhesive agent which can be apply | coated to the said area | region, For example, a thermoplastic adhesive agent etc. can be used suitably.

  The rising angle θ of the side wall 26 of the groove 27 is preferably 40 ° or more, and particularly preferably 50 to 60 °. In the container holder 1 according to the present embodiment, when a finger is inserted into the two finger holes 25 (35) and 25 (35) and lifted, an upward force is applied to the bottom plate 3 to project upward. The bottom plate 3 is easily deformed so that the groove portion 27 is formed on the top plate 2, so that the bottom plate 3 is deformed as described above due to the presence of the side wall 26 of the groove portion 27. You can counter it. In particular, when the rising angle θ of the side wall 26 of the groove portion 27 is 40 ° or more, it is possible to effectively counter the above-described force of the bottom plate 3 to be deformed, and the container is surely secured by the locking piece 32 described later. 100 can be held.

  The bottom plate 3 is formed with six holding holes 31 for holding them in correspondence with six containers arranged in parallel in 2 × 3 rows. The holding hole 31 is formed in the bottom plate 3 with an inner diameter slightly smaller than the outer diameter of the shoulder 114 of the container 100 inserted and held in the holding hole 31.

  A plurality of locking pieces 32 (eight in each holding hole 31 in the present embodiment) capable of locking the insertion tip of the container 100 inserted into the holding hole 31 are arranged at predetermined intervals on the periphery of the holding hole 31. It is formed with. The plurality of locking pieces 32 have a substantially trapezoidal shape, and are formed in a radial shape such that the tip portions 33 thereof are directed toward the center of the holding hole 31. Each locking piece 32 is bent from the base portion 34, and the distal end portion 33 of the locking piece 32 comes into contact with the winding fastening portion 113 of the container 100 inserted into the holding hole 31, whereby the container 100 can be held. (See FIG. 4).

As shown in FIG. 4, the length L ₃₂ from the base portion 34 to the distal end portion 33 of each locking piece ₃₂ is a straight line connecting the winding portion 113 and the shoulder portion 114 of the container 100 held by the container holder 1. As long as it is shorter than the length L, it can be set as appropriate. When the container 100 is inserted into the holding hole 31, the distal end portion 33 is bent upward from the base 34 of the locking piece 32, but the length L ₃₂ of the locking piece ₃₂ is larger than the linear length L. Since the base 34 of the locking piece 32 comes into contact with the enlarged diameter portion 115 of the container 100, the container 100 can be reliably held. Preferably, the length L ₃₂ of the locking piece 32 is 1/3 or more of the linear length L, more preferably 1/2 or more, and particularly preferably 2/3 or more. The length L ₃₂ of the locking piece 32 is less than 1/3 of the straight line length L, a holding force of the container 100 by the container holder 1 according to this embodiment is lowered, the container 100 falls off fear There is.

  The folding pieces 4 and 5 connected to the edge of the short side of the bottom plate 3 via the folding lines 4a and 5a are bent via the folding lines 4a and 5a, and the top plate 2 and the bottom plate 3 Fit between. Thereby, when the container holder 1 is lifted, it is possible to further suppress the container holder 1 (the top plate 2 and the bottom plate 3) from being curved.

  Two locking holes 6a and 6a are formed at the edge of the top plate 2 facing the fold line 2a, and the long side of the bottom plate 3 facing the fold line 2a is connected via the fold line 3a. Thus, two locking claws 7a, 7a that can be inserted into the locking holes 6a, 6a of the upper surface plate 2 to engage the upper surface plate 2 and the bottom surface plate 3 are connected. And the flap 8 is connected with the both sides of the two latching claws 7a and 7a of the long side of the baseplate 3 via the folding line 3a.

  The upper surface plate 2 is formed with a pair of substantially U-shaped cut lines 24A for each container 100 so as to correspond to each of the six containers 100 arranged in parallel in 2 × 3 rows. In addition, a fold line 23 a is formed along the longitudinal direction of the upper surface plate 2. The fold line 23a and the cut line 24A are alternately arranged in the longitudinal direction of the upper surface plate 2, and the end of the fold line 23a and the end of the cut line 24A are continuous. Further, radial cut lines 25 </ b> A reaching the substantially U-shaped cut lines 24 </ b> A are formed on the upper surface plate 2. By forming the substantially U-shaped cut line 24A and the radial cut lines 25A leading to the cut line 24A on the upper surface plate 2, when the container 100 is held by the container holder 1 according to the present embodiment, the container The upper portion of the winding fastening portion 113 of 100 is engaged with the substantially U-shaped cut line 24A, and the effect of improving the holding force of the container 100 is achieved.

Next, the specific operation of the container holder 1 described above will be described.
The upper portions of the six containers 100 arranged in parallel in 2 × 3 rows are inserted into the holding holes 31 of the bottom plate 3. At this time, the locking piece 32 of each holding hole 31 is pushed up by the can lid 112 (winding portion 113) of the container 100, and is bent from the base portion 34 so that the distal end portion 33 faces upward. When the tightening portion 113 passes through the holding hole 31, each locking piece 32 comes into sliding contact with the enlarged diameter portion 115 of the container 100, and the distal end portion 33 of the locking piece 32 comes into contact with the lower side of the winding fastening portion 113. .

  Next, an adhesive (not shown) is applied to the adhesive-applicable region of the bottom plate 3, the top plate 2 is folded along the fold line 2 a, and the two locking claws 7 a, 7 a are locked into the locking holes 6 a, Insert into 6a. In this state, by pressing a region between the two folding lines 21a and 22a of the upper surface plate 2, the upper surface plate 2 and the lower surface plate 3 are bonded to each other while forming the groove portion 27 in the upper surface plate 2. At this time, the upper portion of the winding portion 113 of the container 100 abuts in the vicinity of the substantially U-shaped cut line 24a by bending the upper surface plate 2 along the fold line 23a. And by forming the radial cut line 25A, a flap 29 is formed on the outer side of the cut line 24A of the upper surface plate 2, and the flap 29 rises along the shape of the container 100 (see FIG. 5). . The flap 29 exerts an action of pressing the locking piece 32 abutting on the lower side of the winding fastening portion 113 against the container 100 side (the enlarged diameter portion 115 side). As a result, the locking piece 32 is unlikely to come off from the winding fastening portion 113 of the container 100, and the container 100 can be held more reliably.

  In this way, a packaged product in which a plurality of containers 100 are held by the container holder 1 according to this embodiment is completed. In such a packaged product, the finger holes 25 of the top plate 2 and the finger holes 35 of the bottom plate 3 overlap and coincide with each other, so the finger holes 25 and 35 of the container holder 1 are pushed open with fingers. By inserting fingers into 25 and 35, the top plate 2 and the bottom plate 3 can be lifted together.

  When the packaged product is lifted in this way, an upward force is applied around the finger holes 35 of the bottom plate 3. However, in the container holder 1 according to the present embodiment, by having the groove portion 27 along the longitudinal direction of the upper surface plate 2, the rigidity of the bottom surface plate 3 is increased, and it is possible to counter the upward force, Only the face plate 3 is not greatly curved.

  Further, when an upward force is applied to the periphery of the finger hole 35 of the bottom plate 3 and the bottom plate 3 is greatly curved, the bottom of the container 100 holding only the top is in the direction toward the center of the container holder 1 in plan view. Try to move on. Thereby, among the plurality of locking pieces 32 that hold the container 100, the locking piece 32 that is positioned in the vicinity of the virtual line segment VL <b> 2 that connects the center points of the short sides of the bottom plate 3 is the tightening portion 113 of the container 100. It becomes especially easy to come off. However, in the container holder 1 according to the present embodiment, the bottom plate 3 has a configuration in which the rigidity of the bottom plate 3 is high and it is difficult to bend, thereby preventing the locking piece 32 from being detached from the winding fastening portion 113 of the container 100. The container 100 can be reliably held.

  Further, a downward force is applied to each locking piece 32 according to the weight of the container 100, but the rigidity of the bottom plate 3 is high and the container holder 1 is configured to be difficult to bend as a whole. It is possible to sufficiently counter the downward force applied to the stop piece 32. Therefore, according to the container holder 1 according to the present embodiment, the container 100 in which the distal end portion 33 of the locking piece 32 is in contact with the tightening portion 113 can be reliably held, and the container 100 falls off. This can be suppressed.

  Further, even if an impact is applied to the container holder 1 due to a drop of the container holder 1 holding the container 100 or a cardboard packaging box in which a plurality of container holders 1 are collectively stored, the top plate 2 By bonding the bottom plate 3 and the bottom plate 3 with an adhesive, the strength of the container holder 1 is increased, and it is possible to suppress the occurrence of breakage and the like.

  The embodiment described above is described for facilitating understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  In the said embodiment, although demonstrated taking the case of the container holder 1 which can hold | maintain the six containers 100 arranged in parallel by 2x3 row, this invention is not limited to such an aspect. 2 × n columns (n is an integer greater than or equal to 2), etc., capable of holding 4 containers 100 arranged in 2 × 2 rows, capable of holding 8 containers 100 arranged in 2 × 4 rows, etc. It may be possible to hold the containers 100 arranged in parallel.

  For example, as shown in FIG. 7, in the container holder 1 that can hold four containers 100 arranged in 2 × 2 rows, fingers are inserted into the approximate centers of the top plate 2 and the bottom plate 3, respectively. One finger hole (finger hole) 25, 35 for lifting is formed.

  In substantially the center of the upper surface plate 2, two fold lines 21a and 22a that are substantially parallel to each other and reach two opposing edges of the upper surface plate 2 are formed. By bending along the two fold lines 21a and 22a, the groove portions 27 reaching the two opposite ends of the upper surface plate 2 can be formed. The one finger hole 25, 35 is formed at the approximate center of the top plate 2 and the bottom plate 3 so as to overlap the groove 27.

  In the container holder 1 having such a configuration, for example, one finger is inserted into the finger hole 25 (35) while holding the four containers 100, and one end of the upper surface plate 2 is used with the other one finger. By supporting the part, the container holder 1 holding the container 100 can be lifted.

  In the above embodiment, the top plate 2 and the bottom plate 3 are bonded by an adhesive, but the present invention is not limited to such an embodiment, and the top plate 2 and the bottom plate 3 are bonded. It does not have to be. Further, the surface facing the bottom surface 28 of the groove portion 27 of the top plate 2 may not be in contact with the bottom plate 3. In this case, when the container holder 1 that holds the container 100 is lifted, the bottom plate 3 is somewhat curved. However, since the surface facing the bottom surface 28 of the groove portion 27 of the top surface plate 2 is in contact with the slightly curved bottom surface plate 3, it is possible to prevent the bottom surface plate 3 from being further curved and to sufficiently 100 can be held.

  EXAMPLES Hereinafter, although an Example and a comparative example are given and this invention is demonstrated further in detail, this invention is not limited to the following Example etc. at all.
