Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a packaging bag for containing and selling disposable diapers and sanitary napkins.

[0002]

[Prior Art]

 Generally, the name, design, and descriptive characters of the contents are printed on the surface, a grip is formed at the upper end for carrying, and the contents are contained in a plastic film tube bag with the lower end open, It is known that the diaper is closed, and disposable diapers and napkins for daily life are also packaged in that way. On the other hand, it is also known that a cardboard is interposed between the bag and the container for packing and maintenance.

[0003]

[Problems to be solved by the device]

 In recent years, product materials have been reused for reasons such as resource saving and elimination of pollution. Since disposable diapers and sanitary napkins are manufactured and sold in large quantities, their packaging bags are also large in quantity and are discarded together with general waste. This is not only a waste of resources but also a cause of pollution.

In order to eliminate such an adverse effect, it is preferable that the manufacturer and seller of the packaging bag collect and reuse the packaging bag. However, as mentioned above, the packaging bag has the name, design, and descriptive characters of the contents printed on its surface, so when reusing it, it is necessary to carry out the troublesome work such as removing the printing ink and pigment. It will be forced and the cost will be higher.

An object of the present invention is how to configure the packaging bag so that most of the packaging bag material can be reused without the above-mentioned work. There is a point.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention printed a bag body of a transparent plastic film which is not colored or printed and an appropriate display element such as a design, a character or a symbol. The decorative sheet is composed of a mold-retaining plate releasably attached to the surface of a substrate (cardboard) whose main component is pulp. The mold-retaining plate is placed inside the bag body together with the contents with the surface of the decorative sheet facing outward. It is intended to be housed in.

[0007]

[Action]

 In the packaging bag according to the present invention, the display element of the decorative sheet is seen through from the bag body. When reusing the packaging bag, the bag body should be washed as necessary, and the decorative sheet should be peeled off from the decorative sheet. Discard the decorative sheet as it is.

【Example】

 An embodiment of the packaging bag according to the present invention will be described below with reference to the drawings.

In FIG. 1, a bag body 1 which is a first member constituting a packaging bag forms a tube body having upper and lower ends opened from a transparent plastic film such as polyethylene, and has a V-shaped cross section on both sides. Fold both sides inward, and in that state, join the front and back faces and both sides with heat seal lines 2 and 3 that are vertically separated and extend in the width direction, and have a notch 4 between the seal lines 2 and 3. A grip portion 5 is formed. The bag body 1 has no contents (not shown) or symbols, characters, or symbols for decoration, that is, no coloring or printing. The transparency of the bag body 1 is not particularly limited, but the total light transmittance thereof is preferably 30% or more.

In FIGS. 2 and 3, the mold retaining plate 6 which is the second member constituting the packaging bag is composed of a substrate 7 and a decorative sheet 8 attached to the surface thereof. The substrate 7 has a rigidity that is several times as high as that of the bag body 1, and has, for example, a thickness that is generally called cardboard or cardboard. Performs a protective function. The substrate 7 may be composed mainly of pulp, and may contain a small amount of additives and fillers that do not hinder the reuse of the pulp. However, for reuse, the substrate 7 is manufactured from almost 100% pulp. Those obtained are preferred. In the illustrated example, the substrate 7 is composed of a pair of substrates having a bending groove that can be bent near one side in the width direction, but it may be a box-shaped substrate having other bottom and top surfaces. Good.

The decorative sheet 8 can be manufactured from pulp / plastic or the like that can be printed or given desired decorations. On the surface of the decorative sheet 8, a display element 9 such as a suitable design, character, or symbol for the contents is printed.

The decorative sheet 8 is releasably attached to the surface of the substrate 7. In order to enable peeling, for example, a known adhesive, that is, an adhesive that has a relatively weak adhesive force and does not remain on the substrate 7 at the time of peeling (marketed under the trademark “Post-it” in recent years. It can be applied to the back surface of the decorative sheet 8 such as an adhesive that is applied to a "sticky note") or a water-soluble adhesive containing polyvinyl alcohol as a component. Although not shown, a portion not coated with the adhesive may be provided on the back surface of the decorative sheet corresponding to the corners of the shape-retaining plate 6 and the like, and may serve as a guide portion for peeling the adhesive sheet.

As shown in FIG. 4, the packaging bag having the above-described configuration includes a plurality of disposable diapers or sanitary napkins together with the mold retainer 6 such that the surface of the decorative sheet 8 faces outward in the bag body 1. The above-mentioned contained items are stacked and accommodated, and the lower part of the bag body 1 is appropriately folded and joined to each other and the lower end thereof is closed, so that the contained items are used for packaging.

[0014]

[Effect of the device]

 According to the packaging bag of the present invention, since the display element of the decorative sheet forming the surface of the mold retainer is seen through from the bag body in the packaged state of the contents, the display element is directly printed on the surface of the bag body. Compared to what I did,

After consumption of the contents in the packaging bag, the bag body and the mold retaining plate are separated, the bag body is washed and regenerated as necessary, and the mold retaining plate peels the decorative sheet from the substrate and The substrate can be recycled. In this way, since no complicated removal of the display element is required when reusing the packaging bag material, it is possible to perform the recycling work at low cost, save resources and eliminate pollution. It becomes possible to contribute.
