Description

  The present invention relates to a packaging material.

  2. Description of the Related Art Conventionally, a packaging material that covers and protects a packaged object and prevents damage to the packaged object is known in order to reduce vibrations and impacts acting on the packaged object (see, for example, Patent Documents 1 and 2). .)

  Moreover, in order to prevent the fragments when the packing material is damaged from scattering, or to fix a plurality of packing materials, a tape may be applied around the packing material.

As a method for applying the tape to the packaging material, for example, it is known to simply apply the tape along the outer shape of the packaging material, or to apply the tape along the guide groove formed in the packaging material. (For example, refer to Patent Document 3).
Japanese Utility Model Publication No. 5-54341 JP 2002-2864 A JP 2001-219972 A

  However, when sticking the tape along the outer shape of the packaging material, if the tape is wrapped at an angle of about 90 degrees at the corner of the packaging material, it is difficult to visually recognize the surface to which the tape is wound. There was a problem that it was easy to slip and difficult to wind.

  In the case of Patent Document 3, the tape is applied along the guide groove formed in the entire area of the peripheral surface of the packing material. On the contrary, there is a problem that workability is poor and it is difficult to wind the tape.

  When the tape is displaced or twisted, it may be necessary to rewind the tape so that the tape is reapplied.

  An object of the present invention is to provide a packaging material having a structure in which a tape can be easily wound.

  In order to solve the above-mentioned problems, the invention described in claim 1 is a pair of packing materials made of a foamed resin material, which sandwiches an object to be packed from both sides, and has a generally rectangular shape facing the packing materials. In addition, a notch surface having one notch surface in contact with the facing surface and one guide surface in contact with the notch surface is formed so as to remove four corners of the four corners in a substantially triangular prism shape, and the notch surface The width of the tape wound around and pasted on the surface in contact with the facing surface so as to include the width of the notch surface from the facing surface to the guide surface is substantially the same.

  The invention according to claim 2 is a pair of packing materials made of a foamed resin material that sandwiches an object to be packed from both sides, and at least one corner portion at four corners of a facing surface that has a generally rectangular shape facing the packing material. Is formed in a substantially triangular prism shape, a notch surface having one notch surface in contact with the facing surface and one guide surface in contact with the notch surface is formed, and the facing surface so as to include the notch surface. It is characterized in that a tape is wound around and pasted on the contact surface.

According to a third aspect of the present invention, in the packing material according to the second aspect, the notch is formed at four corners on the facing surface of the packing material.

  According to a fourth aspect of the present invention, in the packaging material according to the second or third aspect, the width of the notch surface from the facing surface to the guide surface is substantially the same as the width of the tape. .

  According to the first aspect of the present invention, the four corners at the four corners of the opposing surface that form a generally rectangular shape that faces when the pair of packing materials made of the foamed resin material sandwich the object to be packed from both sides are substantially each. A notch is formed so as to be removed in a triangular prism shape. The notch portion has one notch surface in contact with the facing surface and one guide surface in contact with the notch surface, and the width of the tape to be wound around the surface in contact with the facing surface so as to include the notch surface, The width from the facing surface of the notch surface to the guide surface in the notch portion is substantially the same.

  For example, when wrapping a tape around the surface of the packing material that contacts the opposing surface, align the side of the tape in the width direction so that it abuts the guide surface of the notch, and attach it to the notch of the notch Since the portion where the guide surface and the notch surface are in contact with each other is parallel to the opposing surface, the tape is wound in a direction parallel to the edge of the opposing surface and the tape is perpendicular to the opposing surface. Can be attached in the direction.

  In particular, since the width from the facing surface of the notch surface to the guide surface is substantially the same as the width of the tape, the tape is notched and the packing material while one side in the width direction of the tape is in contact with the guide surface. If the tape is wound around a surface in contact with the opposite surface, the tape can be wound and pasted so that the other side portion in the width direction of the tape extends along the edge of the opposite surface.

  Moreover, since the notch part is formed in four corner | angular parts in the opposing surface of a packing material, a tape can be aligned with respect to the guide surface in the notch part of each corner | angular part.

  Therefore, the tape aligned on the guide surfaces of the four notches can be more suitably positioned with respect to the surface that contacts the opposing surface of the packing material, and is wound around a more appropriate position. It becomes possible to affix.

  In this way, the packing material in which the corner portion of the facing surface of the packing material is removed in a substantially triangular prism shape, and a notch portion having one notch surface in contact with the facing surface and one guide surface in contact with the notch surface is formed. If so, the tape can be positioned so that the side in the width direction of the tape is brought into contact with the guide surface when the tape is wound around the surface in contact with the facing surface of the packing material. If the tape is wound around the notch surface and the surface in contact with the facing surface of the packaging material while the side portion of the tape in the width direction is in contact with the guide surface, the tape is parallel to the edge of the facing surface. And the tape can be attached in a direction perpendicular to the opposing surface.

  Therefore, when the tape is wound around the surface in contact with the facing surface of the packing material, the direction of the tape can be along the edge of the facing surface, and the tape can be wound and pasted without deviating from the edge of the facing surface. Therefore, it can be said that the packaging material having such a notch is a packaging material that is easy to wind and stick.

  In addition, by forming a notch surface between the surfaces in contact with the opposing surface of the packaging material, which are in contact with the corners of the four corners of the opposing surface having a substantially rectangular shape, the surface in contact with the relatively obtuse angle is formed. It becomes a series. And since it becomes easy to visually recognize the surface where the tape is wound and stuck, it is easy to wind the tape around the surface in contact with the opposite surface of the packing material, and it becomes easy to stick.

  According to the second aspect of the present invention, at least one corner of the four corners of the opposing surface, which has a generally rectangular shape that faces when the pair of packing materials made of the foamed resin material sandwich the object to be packed from both sides, is approximately A notch is formed so as to be removed in a triangular prism shape. The notch portion has one notch surface in contact with the facing surface and one guide surface in contact with the notch surface, and a tape is wound around and pasted on the surface in contact with the facing surface so as to include the notch surface. It is like that.

  For example, when wrapping a tape around the surface of the packing material that contacts the opposing surface, align the side of the tape in the width direction so that it abuts the guide surface of the notch, and attach it to the notch of the notch Since the portion where the guide surface and the notch surface are in contact with each other is parallel to the opposing surface, the tape is wound in a direction parallel to the edge of the opposing surface and the tape is perpendicular to the opposing surface. Can be attached in the direction.

  In other words, the packing material may be a packing material in which a corner portion of the facing surface of the packing material is removed in a substantially triangular prism shape and a notch portion having one notch surface in contact with the facing surface and one guide surface in contact with the notch surface is formed. For example, when the tape is wound around the surface in contact with the facing surface of the packing material, the tape can be positioned so that the side portion in the width direction of the tape contacts the guide surface. If the tape is wound around the notch surface and the surface in contact with the facing surface of the packaging material while the side portion of the tape in the width direction is in contact with the guide surface, the tape is parallel to the edge of the facing surface. And the tape can be attached in a direction perpendicular to the opposing surface.

  Therefore, when the tape is wound around the surface in contact with the facing surface of the packing material, the direction of the tape can be along the edge of the facing surface, and the tape can be wound and pasted without deviating from the edge of the facing surface.

  Therefore, it can be said that the packaging material having such a notch is a packaging material that is easy to wind and stick.

  In addition, by forming a notch surface between the surfaces in contact with the opposing surface of the packaging material, which are in contact with the corners of the four corners of the opposing surface having a substantially rectangular shape, the surface in contact with the relatively obtuse angle is formed. It becomes a series. And since it becomes easy to visually recognize the surface where the tape is wound and stuck, it is easy to wind the tape around the surface in contact with the opposite surface of the packing material, and it becomes easy to stick.

  According to the invention described in claim 3, it is of course possible to obtain the same effect as that of the invention described in claim 2, and in particular, because the notches are formed at the four corners on the facing surface of the packing material. The tape can be aligned with respect to the guide surface at the notch at each corner.

  Therefore, the tape aligned on the guide surfaces of the four notches can be more suitably positioned with respect to the surface that contacts the opposing surface of the packing material, and is wound around a more appropriate position. It becomes possible to affix.

  According to the invention described in claim 4, it is needless to say that the same effect as that of the invention described in claim 2 or 3 can be obtained. In particular, the width from the facing surface of the notch surface to the guide surface is the width of the tape. Since it is substantially the same, if one side of the tape in the width direction is brought into contact with the guide surface and the tape is wound around the surface in contact with the notch surface and the opposite surface of the packing material, the other in the tape width direction A tape can be wound and pasted so that the side portion of the tape extends along the edge of the opposing surface.

  Hereinafter, the packaging material according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the packaging material 10 according to the present invention is used as a pair of two packaging materials 10, and the packing material P is sandwiched between the insides facing each packaging material 10. To hold.

  The packing material 10 absorbs the external force such that an external force such as a drop or vibration acting on the packaged object P held by the packaging material 10 from the outside is difficult to be transmitted to the packaged product P. It can be made of a relatively soft and brittle material, for example, a foamed polystyrene material made of polystyrene resin.

  FIG. 2 is a perspective view showing the inside of the packaging material 10, and FIG. 3 is a perspective view showing the outside of the packaging material 10.

  As shown in FIG. 1 to FIG. 3, the packing material 10 has a substantially rectangular parallelepiped shape, and the opposing surface 1 that is the surface on which the respective packing materials 10 face each other is an accommodation recess for accommodating the article to be packed P. 1a is formed. The left and right edges of the receiving recess 1a are provided with protrusions 2 for separating the packing material 10 facing each other and protecting the article to be packed P stored in the receiving recess 1a.

  In addition, on the outer side surface 3 that is a surface in contact with the facing surface 1 of the packing material 10 and the inner side surface 4 of the housing recess 1a, corrugated portions 33 and 44 having concavities and convexities are formed.

  Then, as shown in FIG. 4, the four notches are formed such that the four corners 1b at the four corners of the facing surface 1 facing each of the packing materials 10 in a generally rectangular shape are cut out into a substantially triangular prism shape and removed. 5 is formed.

  The facing surface 1 of the packing material 10 has a substantially rectangular shape, and the circumscribed surface of the packing material 10 has a substantially rectangular parallelepiped shape. The case will not be rattled and will be housed.

  The notch 5 has a notch surface 5 a that is perpendicular to the facing surface 1, and a guide surface 5 b that is perpendicular to the notch surface 5 a and is parallel to the facing surface 1. In addition, it is preferable to form the notch portion 5 so that the shape of the guide surface 5b is a right-angled isosceles triangle and the angle at which the notch surface 5a and the outer surface 3 are in contact is 45 degrees (135 degrees).

As shown in FIGS. 1 and 5, the tape is applied to the portion of the convex portion 33 a of the corrugated portion 33 on the outer surface 3 of the packing material 10 that is in contact with the opposing surface 1 and the notch surface 5 a. The packing tape T is affixed so as to surround at least one turn around the opposing surface 1.
The length of the side extending from the facing surface 1 to the guide surface 5b in the notch surface 5a of the notch 5 is substantially the same as the width of the packing tape T. That is, the width of the height portion of the substantially triangular prism shape that is removed including the corner portion 1 b of the facing surface 1 so as to form the notch portion 5 is substantially the same as the width of the packing tape T.

  With the cutout portion 5 having such a shape, when the packaging tape T is affixed to the outer surface 3 and the cutout surface 5a of the packaging material 10, one side portion in the width direction of the packaging tape T is applied to the guide surface 5b. The packing tape T can be positioned so that it contacts.

  That is, as shown in FIG. 5, the packaging tape T is affixed to the outer side surface 3 and the notch surface 5a of the packaging material 10 while the side portions in the width direction of the packaging tape T are brought into contact with the guide surface 5b. The other side portion of the packaging tape T can be made to follow the edge of the facing surface 1 of the packaging material 10, and the packaging tape T can be easily wrapped around.

For example, the side of the packaging tape T is pasted so as to protrude from the facing surface 1 side of the packaging material 10 (so as to protrude), or the portion of the outer surface 3 of the packaging material 10 that contacts the facing surface 1 is exposed. If it is stuck, the packing tape T has to be peeled off and the packing tape T has to be re-applied, resulting in extra time for tape application work.

  Therefore, the packing material 10 having the cutout portion 5 that can be positioned so that the side portion of the packing tape T is aligned with the edge of the facing surface 1 of the packing material 10 is easy to wind the packing tape T and easy to stick. You can say that.

  In addition, the outer surface 3 that has been in contact with each other at an angle of about 90 degrees is formed with the notch portion 5 so that the outer surface 3 comes into contact with the outer surface 3 through the notch surface 5a. Come into contact at an angle of about 135 degrees.

  That is, by forming the notch surface 5a between the outer surfaces 3 that are in contact with a relatively acute angle, the surfaces that are in contact with a relatively obtuse angle are connected, and the surface to which the packing tape T is wrapped and pasted is visually recognized. Since it becomes easy, it becomes easy to stick the packing tape T on the outer surface 3 of the packing material 10.

  This packing tape T is affixed in order to attach the generated debris of the packing material 10 so that the debris when the packing material 10 is damaged is not scattered. In particular, while the packing materials 10 are opposed to each other, the debris of the packing material 10 is attached to the packaged material P that is sandwiched and held by the packing materials 10 so that the debris of the packing material 10 does not fall off. Yes.

  The housing recess 1a is formed in a shape that can hold a predetermined object to be packed without rattling, and the tip side of the convex portion 44a of the corrugated portion 44 of the housing recess 1a supports the object to be packed. It is like that.

  In addition, as shown in FIG. 6, when the pair of packing materials 10 holds the article to be packed P and is stored in a case C such as a predetermined cardboard box, the shape does not rattle in the case C. The packing material 10 is formed, and the front end side of the convex portion 33a of the wave-shaped portion 33 of the outer side surface 3 comes into contact with the inner surface of the case C.

  And the convex part 33a of the waveform part 33 and the convex part 44a of the waveform part 44 are easy to deform | transform because of the protruding shape.

  That is, when an external force such as vibration or impact is applied from the outside to the case C in which the packing material 10 and the packaged item P are stored, the convex portion 33a of the corrugated portion 33 and the convex portion 44a of the corrugated portion 44 are By deforming, such as bending, the external force can be absorbed.

  Thus, since the packing material 10 has the notch part 5 formed so that the corner | angular part 1b of the four corners of the opposing surface 1 which each packing material 10 opposes may be removed in substantially triangular prism shape, the notch part 5 By aligning the side portion of the packaging tape T with the guide surface 5b, the side portion of the packaging tape T can be positioned and pasted along the edge of the opposing surface 1 of the packaging material 10.

  Moreover, since the outer side surface 3 and the notch surface 5a contact | connect at a comparatively obtuse angle, it becomes easy to visually recognize the surface where the packing tape T is wound and stuck, so the packing tape T is attached to the outer side surface 3 of the packing material 10. It becomes easy to stick.

  Therefore, it can be said that the packaging material 10 is a packaging material that is easy to wind and stick so that the side portion of the packaging tape T is along the edge of the facing surface 1 of the packaging material 10. Therefore, it is possible to reduce the time for tape application work in which the packaging tape T is wrapped around and attached to the packing material 10.

  And since the packing tape T is affixed along the edge of the opposing surface 1 of the packing material 10, when a broken piece arises when the packing material 10 is damaged with the effect | action of external force etc., the broken piece will scatter. The packing tape T can stick the fragments so that it does not. In particular, the packing tape T adheres to the packing material 10 so that the debris of the packing material 10 does not fall off on the packaged material P side held by the packing material 10 while the packing materials 10 face each other. Therefore, it is possible to prevent the generated fragments from adhering to the packaged item P.

  Therefore, when the case C is opened, troubles that impair the aesthetic appearance that the debris of the packing material 10 has adhered to a new product that is the article to be packed P, or debris enters the inside of the product. This can reduce troubles.

  Moreover, the material cost of the packaging material 10 can be reduced by reducing the volume of the packaging material 10 by reducing the four corners of the packaging material 10 in this way, and the cost can be reduced.

  In the above-described embodiment, the packaging material 10 in which the four notches 5 are formed so as to remove the four corners 1b at the four corners of the facing surface 1 into a substantially triangular prism shape has been described. The four corners 1b at the four corners of the facing surface 1 of the packaging material are not limited to the above, and at least one corner 1b is removed in a substantially triangular prism shape so that at least one notch 5 is formed in the packaging material. Just do it. That is, as shown in FIG. 7, one notch 5 may be formed so as to remove one corner 1 b at the four corners of the packing material 20.

  Thus, when forming the one notch part 5 in the packing material 20, when the packing material 20 is accommodated in the case C, it is preferable that the notch part 5 becomes a lower side. Thereby, when the case C is opened, the notch 5 can be prevented from being visually recognized. In particular, when the packing tape T is aligned at the notch 5, the winding start end and the winding end of the packing tape T are positioned at the notch 5. It can be hidden.

  Moreover, you may make it form the two notch parts 5 which remove two corner parts 1b, and the three notch parts 5 which remove three corner parts 1b.

  Moreover, in the above embodiment, the notch portion 5 has an example in which the notch surface 5a is perpendicular to the facing surface 1 and the guide surface 5b is perpendicular to the notch surface 5a and parallel to the facing surface 1. Although described, this invention is not limited to this, As shown in FIG. 8, the notch part which has only the notch surface 55a like the notch part 55 formed in the packing material 30 may be sufficient. In this case, the packing tape T cannot be aligned like the packing material 10 (the notch portion 5), but the outer surface 3 and the notch surface 55a are in contact with each other at a relatively obtuse angle. It is easy to visually recognize the surface to be wrapped and pasted, and the width of the cut-out surface 55a is wide, so that the packaging tape T can be easily stuck to the outer side surface 3 of the packaging material 30.

  In addition, it is needless to say that other specific detailed structures can be appropriately changed.
