Description

  The present invention relates to a packaging material for covering or protecting an object to be packaged.

  It is well known that so-called shrink wrapping, in which a package is covered in advance with a heat-shrinkable synthetic resin film and a predetermined heat is applied to the package to closely adhere to the package, is generally widely used. . A variety of products that employ such heat-shrinkable resin films as packaging materials range from daily miscellaneous goods to durable consumer goods. Such a packaging material is generally configured such that the heat-shrinkable film is very thin and is easily broken for the purpose of improving the ease of opening. Therefore, there is no buffering property, and there is no role to protect the packaged goods from impacts and scratches. When protection of such a packaged item is required, a measure is taken in which the packaged item is surrounded by a cushioning material and packed in a box and then covered with a heat-shrinkable film as described above. I came.

  On the other hand, the cushioning material and the packaging material as described above are combined and further rationalized, for example, Japanese Patent Laid-Open No. 59-51027, Japanese Patent Laid-Open No. 59-51066, or Japanese Patent Laid-Open No. 60-2466. And the like as disclosed in the Japanese Patent Publication. A feature common to these techniques is an excellent feature that a packaging object is covered with a heat-shrinkable resin film having foamability, and a buffering effect is obtained together with the covering effect. However, on the other hand, there are problems such as a decrease in transparency of a resin film as a packaging material and a decrease in ease of opening.

  In addition, while placing the item to be packaged on a mount on which sales promotion information is displayed and protecting the back of the item to be packaged, the surface is covered with a transparent heat-shrinkable resin film so There was a package that was devised to prove. Typical examples of such a technique include the techniques disclosed in Japanese Patent Laid-Open Nos. 60-134867, 8-40456, and 10-316164. Although these techniques can be expected to improve the sales promotion effect, there is a problem that the packaging work takes time and costs are increased. In addition, during storage and packaging, the shape is distorted, causing a collapse of the cargo, and so on.

  Saves resources from ordinary box-shaped packages, provides cushioning and scratch protection to protect the package from impacts and scratches, etc., and provides stability for packing during storage and storage, or storage for orderly packing In addition to improving the display properties at the time of display or exhibiting, it has unopenedness to prove the presence or absence of opening, while improving the anti-breaking property to prevent the resin film covering the packaged item from being broken, It is an object to provide a low-cost package that is easy to open.

  Almost the entire package is covered with a highly transparent heat-shrinkable resin film so that the package can be visually recognized from the outside in a resource-saving and low-cost manner and unopened. It should be noted here that, of course, the transparency of the film is not necessarily required. Then, at least two substantially parallel surfaces of the body to be packaged coated with the film, preferably on the outer surface of the film at the upper and lower surface positions, a predetermined component formed mainly of paper or the like so as to cover the both surfaces, respectively. It is characterized in that the protective members having an area are each stuck and disposed via an adhesive or the like.

  In addition, the protective members are connected to each other through a connecting portion, have a substantially strip shape as a whole, and are formed so that one side surface has a substantially U-shape. In addition, a predetermined shape of the die is cut in a predetermined area of the protective member to improve the decoration. In addition, a perforated half-cut line is formed in advance at a predetermined position of the heat-shrinkable film to improve the ease of opening.

  According to the present invention, similarly to the conventional shrink wrapping, there is an effect that it is possible to ensure unopenedness indicating the presence or absence of opening. In addition, the effect of protecting the article to be packaged from scratches and impacts can be improved to a high level when compared with a conventional package made of shrink wrapping. Compared with a box as a conventional packaging material, There is an effect that a certain degree of protection can be obtained while being low cost and resource saving.

  Further, the working efficiency of the packaging process can be improved as compared with the conventional box, and the ease of opening can be improved and the convenience can be improved. In addition, by arranging the protective member outside the heat-shrinkable film, not inside the heat-shrinkable film, there is also an effect that it is possible to protect the heat-shrinkable film that is easily damaged and easily torn.

  In addition, the protective members placed on the upper and lower surfaces formed so as to exceed the planar shape of the packaged item, the packaged item is in a semi-boxed state, and it is easy to stably store and store it as if it was packed in a box. There is an effect of becoming. In addition, unlike the box, the protective member has a configuration in which at least a part of the periphery is missing, so that there is an effect that the packaged body can be visually recognized from the side surface or the front surface. Furthermore, when sales promotion information is displayed on the package or the like, there is an effect that a sales promotion effect can be expected.

  A preferred embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a perspective view of an article to be packaged (2) which is a packaging target of the package (1) of the present invention, and FIG. 2 is a heat-shrinkable film (before heat-shrinking) formed in a rectangular cylinder shape. It is a perspective view which shows the state which accommodated the to-be-packaged item (2) in the approximate center in 3). FIG. 3 is a perspective view showing a state in which the heat-shrinkable film (3) is heated and shrunk in the state of FIG. 2, and the film (3) is brought into close contact with the packaged object (2). FIG. 4 is a perspective view of the protective member (4) in which one side surface shape is formed in a U-shape by bending a predetermined portion of the belt-shaped protective member (4) in a deployed state. FIG. 5: is a perspective view which shows the state which gave the packaging to the to-be packaged object (2) using the package body (1) to which the said invention is applied. 6 is a development view of FIG. 4, FIG. 7 is a development view of a modification of the protection member (4), and FIG. 8 is a perspective view showing a three-dimensional state of the protection member (4) of FIG. .

  The article to be packaged (2), which is the packaging target of the packaging body (1) of the present invention, should not be damaged by deformation or the like when heated to shrink the heat-shrinkable film (3). However, there is no particular limitation other than this. Here, the article to be packaged (2) shown in FIG. 1 is, for example, a lidded container made up of a lid body that contains cosmetics, hairdressing materials, and the like and a container body.

  As shown in FIG. 2, the heat-shrinkable film (3) constituting the package (1) of the present invention is a single heat-shrinkable resin film having a width and length that can surround the package (1). The two opposite sides are melt-pressed and joined to form a substantially rectangular tube shape. The article to be packaged (2) is accommodated in substantially the center of the inside of the heat-shrinkable film (3) having a rectangular cylindrical shape. The heat-shrinkable resin film can be appropriately selected from conventionally used general-purpose products, but may be any film body having heat-shrinkability, and is not particularly limited, but among such general-purpose products, For example, when a highly transparent film such as a polyethylene terephthalate (PET) film or a polystyrene (PS) film is used, the object to be packaged (2) can be visually recognized from the outside.

  FIG. 3 shows a state in which the heat-shrinkable film (3) having a substantially rectangular tube shape is heated and contracted at an appropriate temperature in a state in which the article to be packaged (2) is housed. As shown in FIG. 3, since the cylindrical heat-shrinkable film (3) is heated, the opening (5) before and after the film shrinks while being opened, and when opening, this circularly shrunk opening The heat-shrinkable film (3) can be torn off from the edge of the part (5), and the ease of opening is improved. At this time, for the purpose of further improving the ease of opening, it is also possible to previously form a perforated half cut line at a predetermined position of the heat-shrinkable film (3).

  As shown in FIG. 4, the protective member (4) in this example is formed so that one side surface shape becomes a U-shape. This protective member (4) is formed by bending a predetermined portion of a plate-shaped cardboard having a rectangular unfolded state. Here, although the material of the protective member (4) is paper, any material can be used as long as a desired protective effect can be obtained, and the material is not limited to paper. Further, the size of the protective member (4) is such that the two surfaces facing each other in the folded state as shown in FIG. 4 cover the predetermined surface of the package (2), here the upper and lower surfaces. The size of is defined. Of course, it goes without saying that the shape of the surface of the protective member (4) covering the upper and lower surfaces of the article to be packaged (2) is not limited to a square, and may be a rounded shape. Also, the height of the side surface connecting the upper and lower surfaces of the protective member (4) for protecting the upper and lower surfaces must be at least equivalent to the height of the package (2). Further, an adhesive portion (6) for bonding the protective member (4) and the heat-shrinkable film, which is made of a pressure-sensitive adhesive, to the substantially central portion of each of the two opposing surfaces of the protective member (4). Is formed. As this adhesive, a conventionally known technique such as a double-sided pressure-sensitive adhesive tape can be suitably used. Here, the position of the bonding portion (6) is set at the center, but of course, it may be a peripheral portion, or may be a dotted bonding portion, a linear shape, or a planar shape.

  In particular, as shown in FIG. 5, the upper and lower surfaces of the protective member (4) are pasted to predetermined positions on the upper and lower surfaces of the packaged object (2) covered with the heat-shrinkable film (3) through the adhesive portions (6). At the time of wearing and opening, the protective member (4) is peeled off from the heat-shrinkable film (3). At this time, the heat-shrinkable film (3) together with the protective member (4) is peeled off by the peeling force. You may form a half cut line and an adhesion part (6) so that it may tear and open.

  As shown in FIG. 6, the protective member (4) of the package (1) configured as described above has a rectangular unfolded state, but is not limited to this, and is shown in FIGS. Like the protective member (4), the width of the connecting portion is curved inward, or a desired die-cut through hole is formed on each surface forming the upper surface (7) or the lower surface (8) of the protective member (4). (9) can be provided to improve design and the like.
