Description

  The present invention relates to a packaging box, and more specifically, versatility that an article of various shapes can be easily and stably held, and even if a part of a holding member holding the article is damaged, the necessary minimum The present invention provides a packaging box that combines the economics of being able to be exchanged.

  Conventionally, as an example of a packing box, a holding force is generated by flexible deformation of a thin film and its tension, for example, using two film frames in which an elastic film such as polyurethane thermoplastic elastomer is stretched, A packaging box in which an article is sandwiched between the elastic films and buffered is known (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2001-192067 (page 2-6 (claim 46), FIG. 16)

  Specifically, as shown in FIG. 5, the conventional packaging box B is stretched by the pressing force generated when the article W is sandwiched by the film frame 20 and the elastic film 30 is fitted to the shape of the article W. By the action, the article W is buffered and held so as to be suspended in the outer box 10. However, the conventional packaging box B has the following problems.

  That is, as shown in FIG. 5A, when an article W having a sharp protruding portion S is to be packed in the conventional packaging box B, a portion of the elastic film 30 that contacts the protruding portion S of the article W is As a result, the article W may not be held.

  Further, as shown in FIG. 5 (b), when an article W having an asymmetric shape is vertically packed in the conventional packaging box B, the elastic film 30 fits in a bulky portion of the article W. The elastic film 30 is in close contact with the Wb surface (the surface of the portion having a high bulk) by surface contact, but the film 30 is not in close contact with the Wa surface (the surface of the portion having a low bulk) due to surface contact. As a result, the holding force varies in the step portion, which causes the position shift, vibration, and dropout of the article W. Thus, in the said conventional packaging box B, there existed a problem that the shape of the goods W which can be packed will be restricted.

  Further, in the conventional packaging box B, when a part of the elastic film 30 is damaged, it is structurally impossible to repair only that part. The elastic film 30 must be exchanged, and there was a problem in terms of economy.

  Therefore, the present invention has been made to solve the above-mentioned problems, and the object of the present invention is to have versatility that an article of various shapes can be easily and stably held, and an article. It is an object of the present invention to provide a packaging box that combines economic efficiency that even if a part of the holding member to be held is damaged, it can be replaced with the minimum necessary.

  In order to solve the above-mentioned problem, in the invention of the packaging box according to claim 1, the pair of frames provided with an opening at the center and the openings so as to cover a part of the openings of each frame. A belt-like elastic member attached to each frame in a state of being stretched across the section, the openings of the pair of frames are opposed to each other, and the article is held by the opposed belt-like elastic members Is.

  The invention in the packaging box according to claim 2 is characterized in that, in the invention according to claim 1, the belt-like elastic member is detachably attached to each frame body.

  The invention in the packaging box according to claim 3 is characterized in that, in the invention according to claim 1 or 2, an outer box for storing the pair of frame bodies is provided.

  A packaging box according to the present invention is attached to each frame body in a state of being stretched over the opening portion so as to cover a part of the opening portion of each frame body and a pair of frame bodies having an opening portion provided in the center portion. The belt-shaped elastic member is configured such that the openings of the pair of frames are opposed to each other, and the article is held by the opposed band-shaped elastic members.

  Accordingly, the elastic band-like elastic member having elasticity and flexibility extends along the shape of the article, and the tension holds the article in the hollow space in the internal space of the pair of frame bodies. It can be buffered to prevent damage to the article. Moreover, since the entire surface of the article is not covered with an elastic film as in the prior art, the air permeability is very good.

  Moreover, the said strip | belt-shaped elastic member becomes a structure attached to each said frame body so that attachment or detachment is possible.

  Therefore, when the article on which the sharp protrusions are formed is held by the pair of frames, the attachment position of the belt-like elastic member can be changed to a position where the protrusions of the article can be avoided, and the article can be held. . As a result, the packaging box according to the present invention has versatility that it can pack articles of various shapes, and even if a part of the belt-like elastic member is damaged, only the corresponding belt-like elastic member is replaced. Therefore, it has the effect of being economical.

  In addition, since it is possible to change the tension of the belt-like elastic member, for example, when holding an article having an asymmetric shape at the top and bottom with the pair of frames, depending on different parts such as the shape and volume of the article The article can be held with an appropriate holding force by using belt-like elastic members having different tensions as appropriate. As a result, the packaging box according to the present invention has the effect of versatility that it can package articles of various shapes.

  Furthermore, it is the structure provided with the outer box which accommodates a pair of said frame.

  Therefore, when the pair of frames holding the articles are stored in the outer box, a component for locking the pair of frames so that they are not separated from each other by the repulsive force of the belt-like elastic member is unnecessary. Become.

  Next, an embodiment of a packaging box according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is an exploded perspective view for explaining a state in which an article W is packed in a packaging box B according to the present invention. As shown in FIG. 1, a packing box B for packing an article W is generally an outer box 1, a pair of frames 2, 2 having the same shape housed in the outer box 1, and the frame There are provided strip-like elastic members 3 and 3 having stretchability and flexibility respectively stretched over the bodies 2 and 2.

  Each of the frame bodies 2 and 2 includes a frame portion 2b provided with a square opening 2a at the center and a support portion 2c provided in a direction perpendicular to the frame portion 2b. Is formed. Note that the height of the support portion 2c is appropriately changed according to the shape and volume of the article W to be packed.

  The belt-like elastic members 3 and 3 are attached to the frame bodies 2 and 2 in a state of being stretched over the opening 2a so as to cover a part of the opening 2a of the frames 2 and 2. Specifically, the end portions of the belt-like elastic members 3 and 3 are arranged on the frame portion 2b of the frame bodies 2 and 2 so that they are parallel to the opposite two sides of the opening portions 2a of the frame bodies 2 and 2, for example. It is detachably attached by a fixing member 4 such as a staple.

  Examples of the material of the belt-like elastic member 3 include rubber materials (natural rubber, urethane rubber, fluorine rubber, butadiene rubber, butyl rubber, NBR, CR, SBR, EPDM, etc.), soft resin materials (polypropylene resin, polyethylene resin, chloride). Vinyl resin, ethylene vinyl acetate resin, etc.) and thermoplastic elastomer materials (polyurethane, polyester, olefin, styrene, polyamide, vinyl chloride, etc.). Of these, polyurethane-based thermoplastic elastomers are preferable in consideration of tensile strength and flexibility, and natural rubber is preferable in consideration of durability.

  The material of the outer box 1 is not limited as long as the article W is held by the frame bodies 2 and 2 so as to be sandwiched from above and below, and can be safely transported. Depending on the size and weight of the article W and the frames 2 and 2, in addition to corrugated cardboard boxes, plastic boxes such as polyester and polyethylene, single paperboards or carton-type boxes with multiple paperboards, etc. are used according to the application. do it.

  In addition, about the shape of the said outer box 1, from a viewpoint of workability | operativity at the time of storing or taking out the frames 2 and 2 with which the articles | goods W were hold | maintained, for example, the shape which is a rectangular parallelepiped shape and any one surface can be opened completely. It is preferable that

  In order to pack the article W in the packing box B, the pair of frame bodies 2, 2 are opposed to each other so that the belt-like elastic members 3, 3 stretched over the frame bodies 2, 2 are directed upward and downward, respectively. The article W is sandwiched between the band-like elastic members 3 and 3. As a result, the band-shaped elastic members 3 and 3 extend along the shape of the article W, and the article W is held in a hollow state in the internal space of the frame bodies 2 and 2 by the tension of the band-shaped elastic members 3 and 3. . Then, the pair of frames 2 and 2 holding the article W therein are accommodated in the outer box 1 and are transported or stored in this state.

  The order in which the articles W are packed in the outer box 1 is not limited to the example described above, and one of the pair of frames 2 and 2 is stored in the outer box 1 in advance. Alternatively, the article W may be placed thereon, and then the article W may be sandwiched between the other frame bodies 2 and the cover of the outer box 1 may be closed.

  As described above, the elastic elastic members 3 and 3 having elasticity and flexibility extend along the shape of the article W, and the article W is held in a hollow state in the internal space of the frames 2 and 2 by the tension. It is possible to prevent the article W from being damaged by effectively buffering the impact from the article. Moreover, since the entire surface of the article W is not covered with an elastic film as in the prior art, the air permeability is very good.

  Further, not only the above-described impact resistance is improved, but also the pair of frame bodies 2, 2 holding the article W in the outer box 1, the pair of frame bodies 2, 2 are band-like elastic members 3. The means for locking so as not to be separated from each other by the repulsive force of 3 becomes unnecessary.

  In the present embodiment, the example in which the pair of frame bodies 2 and 2 holding the article W is stored in the outer box 1 has been described. However, the present invention is not limited to the present embodiment. For example, if the fastening means such as a tie-down strap is used to fix it in contact or close proximity, it can be transported or stored in that state.

  Next, a second embodiment of the present invention will be described with a focus on differences from the first embodiment. FIG. 2 is a perspective view when the article W on which the sharp protrusion portion S is formed is held by a pair of frames (not shown). As shown in FIG. 2 (left figure), when the article W having the shape is sandwiched between the pair of frames (not shown), the protrusion S may become an obstacle and the article W cannot be held. It is done.

  In such a case, as shown in FIG. 2 (right figure), the upper and lower belt-like elastic members 3 and 3 are once removed from the frame (not shown), and first, the upper portion is moved to a position where the protruding portion S can be avoided. The attachment position of the belt-like elastic member 3 is changed. Then, the attachment position of the lower belt-like elastic member 3 is changed to a position corresponding to the upper belt-like elastic member 3. Thus, if the band-shaped elastic member 3 is reattached to a position where the protruding portion S can be avoided to hold the article W, the article W can be held without damaging the band-shaped elastic member 3. . In addition, since an excessive force is not applied to the protruding portion S, the article W is not damaged.

  Note that the attachment position of only the upper belt-like elastic member 3 may be changed without changing the position of the lower belt-like elastic member 3. Also, if the article W is made of a material that is not easily damaged, the mounting positions of the upper and lower belt-like elastic members 3 and 3 are not changed, and only the upper belt-like elastic member 3 is forced to avoid the protruding portion S. May be.

  Therefore, the packaging box B according to the present invention has the versatility that it can pack articles W of various shapes, and even if a part of the band-shaped elastic member 3 is damaged, only the corresponding band-shaped elastic member 3 is used. Since it only needs to be exchanged, it has the effect of being economical.

  In the present embodiment, the belt-like elastic members 3 and 3 are stretched over a part of the opening 2a of each frame 2 and 2 so as to be parallel to two opposing sides of the opening 2a of the frame 2 and 2. However, the present invention is not limited to this embodiment. For example, the frame 2 or 2 may be stretched in the diagonal direction of the opening 2a, or may be formed on two orthogonal sides of the opening 2a. You may stretch across the cross.

  Further, for example, the belt-like elastic members 3 and 3 are stretched so as to be parallel to the long side of the opening 2a of the one frame 2, and so as to be parallel to the short side of the opening 2a of the other frame 2. The article W may be sandwiched and held between the frame bodies 2 and 2.

  As for the number of the belt-like elastic members 3, it is preferable to attach two or more pieces to the frame bodies 2, 2 in order to hold the article W firmly, but if the shape of the article W is, for example, a simple plate-like shape Alternatively, the wide band-like elastic member 3 may be stretched over the frame bodies 2 and 2 one by one to hold the article W.

  Next, a third embodiment of the present invention will be described with a focus on differences from the first embodiment and the second embodiment. FIG. 3 is a schematic side view when the tension of the belt-like elastic member 3 is changed, and FIG. 4 is a belt-like shape in which an article W having an asymmetric shape is vertically stretched between a pair of frames (not shown). It is a perspective view when hold | maintaining with the elastic members 3 and 3. FIG.

  In the third embodiment, as shown in FIG. 3, a plurality of tension adjusting holes 3a are formed at both ends of the belt-like elastic members 3 and 3 at a predetermined pitch. The tension adjusting hole 3a has a keyhole shape including a circular large-diameter hole 3b and a small-width hole 3c continuously cut out from one end of the large-diameter hole 3b.

  Further, fixing members 4 for fixing the belt-like elastic members 3, 3, for example, countersunk head screws with cross holes (JIS B1112-1995) are provided on both long sides of the support portions 2 c of the frames 2, 2. ) Are attached two on each side.

  As a result, the large-diameter hole portion 3b of the tension adjusting hole 3a is locked by the countersunk wood screw with the cross hole, and the belt-like elastic member 3 is not easily dropped by the tensile reaction force of the belt-like elastic member 3. It has become. When the belt-like elastic member 3 is removed from the fixing member 4 (a countersunk head screw with a cross hole), the fixing member 4 (a countersunk head screw with a cross hole) is pulled so as to come to the position of the narrow hole 3c, and the state The belt-like elastic member 3 is twisted and removed.

  In order to exert sufficient tension on the belt-like elastic member 3, as shown in FIG. 3, the belt-like elastic member 3 is once removed from the fixing member 4, and the belt-like elastic member 3 is pulled in the X direction. The belt-like elastic member 3 is hooked on the fixing member 4 so that the position of the tension adjusting hole 3 is changed from the position A to the position B. In addition, what is necessary is just to perform the above-mentioned reverse operation, when loosening the tension | tensile_strength of the said strip | belt-shaped elastic member 3. FIG.

  Here, as shown in FIG. 4, for example, an approximately L-shaped article W having a different bulkiness between the Wa portion and the Wb portion is stretched over a pair of frames (not shown). In the case where the members 3 and 3 are held, the elastic band 3 in charge of the Wa portion cannot hold the Wa portion with an appropriate holding force unless it has an appropriate tension.

  Therefore, the position of the tension adjusting hole 3a is changed so that sufficient tension is exerted on the belt-like elastic member 3 in charge of the Wa portion. Thereafter, a pair of frames (not shown) are opposed to the band-like elastic members 3 and 3 stretched over the frame so as to face upward and downward, and the article W is sandwiched between the band-like elastic members 3 and 3. To.

  In this way, the article W having the shape is held with an appropriate holding force by using the band-shaped elastic members 3 and 3 having different tensions as appropriate according to the Wa portion having a low bulk and the Wb portion having a high bulk. it can. Therefore, the packaging box B according to the present invention has versatility that it can package articles W having various shapes.

  In the present embodiment, a plurality of keyhole-like tension adjusting holes 3a are formed at both ends of the band-like elastic members 3 and 3 at a predetermined pitch, and the positions of the tension adjusting holes 3a are changed to change the positions of the band-like elastic members 3, 3 Although the example which adjusts the tension | tensile_strength of this is demonstrated, when making the said strip | belt-shaped elastic members 3 and 3 exhibit sufficient tension | tensile_strength, it is presently the strip | belt-shaped elastic member currently attached to the frame (not shown). When the belt-like elastic member 3 shorter than 3 is replaced and, on the contrary, the tension of the belt-like elastic member 3 is relaxed, the belt-like elastic member longer than the belt-like elastic member 3 currently attached to a frame (not shown). It may be replaced with 3.

It is a disassembled perspective view explaining the state which packs the goods W in the packaging box B concerning this invention. It is a perspective view when the articles | goods W in which the sharp protrusion part S was formed were hold | maintained with a pair of frame (not shown). It is a schematic side view when changing the tension of the belt-like elastic member 3.
