Description

  The present invention relates to a wrapping paper box that also serves to display a relatively high-grade product such as a progressive article.

  In general, a wrapping paper box is composed of a box main body that stores products and a box-frame-shaped lid that covers the box main body. For example, for wrapping articles such as hams and alcoholic beverages for gifts, The box body is generally used in which the four-side plate portion of the box body is lowered to about ½ of the box inner height. This is because if the box body is shallow, the product appears to be raised higher than the box body when the lid is removed, so that the volume of the product can be emphasized and the appearance when displayed is improved.

However, if the four-circumference side plate portion of the box body is simply lowered as described above, the rigidity and strength in the packaging state in which the lid is fitted will be reduced. Therefore, conventionally, a downward stepped portion is provided in parallel on both inner surfaces of the pair of side plates facing the lid, and the upper edge of the side plate lowered on the box body when the lid is fitted to the box body. Are used so as to be in contact with the stepped portion and increase the rigidity and strength of the packaging paper box (Patent Documents 1 and 2).
Utility Model Registration No. 2529940 However, even in the conventional packaging paper box using a shallow box body and a lid with a stepped portion as described above, it cannot be said that rigidity and strength are sufficient, and heavy products are stored in storage and transportation. When the boxes are stacked together, the weight is supported by the stepped parts on both sides of the lid, so the stepped parts are crushed by the lower weighted box, causing deformation of the entire box and damage to the product. There was a fear. In addition, the shallow box body has a problem in that the stability of the product is poor when the display is stood diagonally with the lid removed.

  In view of the above circumstances, the present invention can enhance the volume of a product as a wrapping paper box, can look good, has excellent rigidity and strength, can be stacked during storage and transportation, and has a lid removed. The object is to provide a product that can ensure the stability of the product when it is displayed obliquely in a state.

  In order to achieve the above object, a wrapping paper box according to claim 1 of the present invention includes a box main body having a rectangular bottom plate and a four-side plate and opened upward, a rectangular top plate and a four-side plate. And has a lid that is externally fitted to the box body. On both inner surfaces of a pair of opposing side plates of the lid, downward stepped portions are formed in parallel, and one opposing side plate of the box body. In the state where the portion is formed higher than the other opposing side plate portion and the lid body is fitted to the box body, the upper end edges of the lower side plate portions of the box body abut against the stepped portion of the lid body, and the box body The upper end edges of the two high-side plate portions are configured to contact the inner surface of the top plate portion of the lid.

  In such a wrapping paper box, the invention according to claim 2 is characterized in that a groove is formed between both end portions of each step portion of the lid and the inner surface of the side plate portion not provided with the step portion. In a state where the body is fitted to the box main body, both side portions of the high side plate portion of the box main body are configured to be fitted into the groove portion.

  According to a third aspect of the present invention, the box body and the lid are formed by bending a sheet of cardboard or cardboard. In the configuration of claim 3, the invention according to claim 4 is characterized in that the box body and the four-side plate portions of the lid form a double wall by folding the sheet, and the double wall of one adjacent side plate portion. A folding piece provided between the other side plate portions or a folding piece provided between the other side plate portions is sandwiched therebetween.

  On the other hand, in the invention of claim 5, in the wrapping paper box of claims 1 to 3, the box body has the stepped portions on both sides of the lid body with the lid body in an inverted state turned upside down as a base. It can be placed on top.

  In the wrapping paper box according to the invention of claim 1, the box body has the upper edge of the lower side plate portion on the stepped portion of the lid body, and the upper edge of the same high side plate portion on the inner surface of the top plate portion of the lid body, Since the lid is supported by the entire four-side plate part in contact with each other, large rigidity and strength can be secured, and even when stacked in multiple stages during storage or transportation, deformation of the box and damage to the product accompanying this are unlikely to occur. It will be a thing. Thus, the box body can lower the one side plate portion of the four-circumferential side plate portion, particularly the pair of side plate portions along the longitudinal direction, so that the volume of the product can be sufficiently provided when the lid is removed. At the same time, when the display is stood diagonally with the lid removed, the lower side of the product can be supported by the wide side plate on the lower side by positioning the high side plate at the upper and lower positions. Will improve.

  According to the invention of claim 2, in the above wrapping paper box, since both side portions of the high side plate portion of the box body are fitted into the groove portion of the lid body, rigidity and strength in a state where the lid body is fitted to the box body. There is an advantage of improving.

  According to the invention of claim 3, the box body and the lid can be assembled and manufactured easily and at low cost by bending a single sheet of cardboard or cardboard.

  According to the invention of claim 4, each of the box body and the lid body made of the single sheet has side walls adjacent to each other between the double walls, in addition to the fact that the four side plates have a double wall structure and great rigidity. Since the side plate parts are strongly integrated with each other by sandwiching the folded piece formed on one or both of the parts, the strength becomes higher.

  According to the invention of claim 5, since the lid body in the inverted state can be used as a pedestal and the box body can be placed thereon, the appearance of the product can be further improved by raising the position of the product during the display.
