Abstract

PURPOSE:To wrap a napkin easily and quickly by a method wherein a napkin wrapping material is simply folded and a fold end is finally secured with a tuck seal or a separable pressure-sensitive adhesive layer. CONSTITUTION:The longitudinal sides X of a wrapping material 2 positioned opposite to the longitudinal sides of a sanitary napkin are folded lengthwise inwardly. The lateral sides Y1 and Y2 of the wrapping material 2 positioned opposite to the lateral sides of the napkin, together with the napkin 1, are folded widthwise inwardly in that order, laid one upon the other to a predetermined overlapping length. The upper lateral side Y2 of the wrapping material is finally secured to the lower lateral side thereof by means of a tuck seal 3 or a separable pressure-sensitive adhesive layer, thereby completing the wrapping of the napkin 1. This wrapping may also be made with a strippable paper placed on a pressure-sensitive adhesive layer 4 or by using the wrapping material 2 treated with a mold release agent instead of attaching the strippable paper.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for packaging sanitary napkins.

[Conventional technology]

Currently, a packaging form as shown in FIG. 4 is used for packaging sanitary napkins. That is, the sanitary napkin 1 is folded and stored in a bag-shaped outer packaging material 10 made of a film packaging material such as polyethylene, polypropylene, polybutadiene, ethylene vinyl alcohol, etc., and predetermined areas of the packaging material 10 are heat-sealed 11 to seal the packaging material. When opening the napkin 1, the napkin 1 is taken out by tearing the outer packaging material 10 along the perforations 12.

On the other hand, since the napkin 1 is partially provided with an adhesive layer 4 on its surface to prevent positional displacement during use, the adhesive layer 4 is placed on the adhesive layer portion to prevent the adhesive layer 4 from adhering to the outer packaging material 10. Usually, a release paper 5 is attached, and after the outer packaging material is opened and taken out, the above-mentioned ff, II, II, and 13 are peeled off before use.

[Problem to be solved by the invention]

However, when packaging napkins, the conventional packaging method described above requires a process of heat-sealing the packaging, which makes the packaging process complicated and increases packaging costs. There was a drawback that the seams were easily torn and opened due to pressure.

The present invention was made to solve the above problems, and it is possible to package napkins with a simple work process, resulting in a reduction in product costs, and the packaging can be easily opened using external pressure. To provide a method for packaging sanitary napkins in a packaging form that does not cause any risk of damage.

(!!!Means for Solving the Problem) That is, the present invention provides the following steps: (1) After placing a sanitary napkin on an expanded packaging material whose size is at least larger than the outer shape of the napkin,
Both ends of the packaging material located on the long side of the napkin are folded inward along the long side direction, and then both ends of the packaging material located on the short side of the napkin are folded in the direction of the short side. After folding the napkin inward by a predetermined amount along the inside, the uppermost short side edge of the packaging material is fixed to the surface of the overlapping packaging material via an adhesive seal or a removable adhesive layer. A method for packaging sanitary napkins, which comprises packaging.

(2) The method for packaging sanitary napkins according to claim 1, wherein a packaging material is used in which a release treatment layer is formed on one side of a film base material to have release properties against the adhesive layer of the napkin.

(3) The method for packaging sanitary napkins according to claim 1, wherein the napkin is packaged by pasting a release paper on the adhesive layer.

The main points are as follows.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.・First
The figure shows one embodiment of the present invention, and according to the method of the present invention, a sanitary napkin 1 is packaged through the steps shown in (a) to (d) of the figure.

First, place iI! on packaging material 2 where napkin 1 is unfolded. Place (
Figure 1(a)). The packaging material 2 is a sheet-like material having a size larger than at least the outer shape of the napkin. next,
The side ends X, X of the napkin of the packaging material 2 located on the long sides are bent inward along the long sides (see the same figure)). If the napkin I has a side guard portion 8, the side guard portion 8 is also folded at the same time. Next, packaging material 2
i,'l located on the short side of the napkin #A part Y,,
One by one, the napkin 1 is folded inward by a predetermined amount along the short side direction ((C) in the same figure). For example, after folding the napkin l with the side end Y1 in between so that the napkin l is divided into approximately two equal parts in the long side direction and folded over, the side end Y1 is
Fold it back and fold it over the side edge Y1.

Finally, the uppermost side end (Y2) of the packaging material 2 is fixed to the overlapping and abutting packaging material surface via the tack seal 3 or a removable adhesive layer (not shown), and the napkin 1 is Packaging is done (FIG. 2(d) and FIG. 2).

The tack seal 3 is not limited to being separate from the packaging material 2 as in this embodiment, but may be an integral part attached to the side end (Y2) of the packaging material 2. The adhesive layer that can be reused may be separately supplied at the time of packaging, or may be provided at a predetermined location on the packaging material from the beginning.

The sanitary napkin 1 is always provided with an adhesive layer 4, but in the method of the present invention, a release paper 5 may be pasted on the adhesive layer 4 before packaging, or a package may be packaged after being subjected to a release treatment as described below. If Material 2 is used, packaging can be done without attaching Mi NM 5.

The packaging material 2 used in the present invention is not particularly limited as long as it has a larger size than the outer shape of the napkin l and is flexible enough to be easily folded, and various materials can be used without restriction. be able to.

As for the overall shape of the packaging material 2 in the unfolded state, in addition to the rectangular shape that follows the outer shape of the napkin as in this embodiment, arbitrary shapes such as a shape consisting of a north side with a rounded short side end of the napkin are adopted. can.

As the packaging material 2 made of a preferable type and material, when a napkin is packaged by pasting a release paper 5 on the adhesive layer 4, a packaging material made of a film of polyethylene, polypropylene, polybutadiene, ethylene vinyl alcohol, etc. is used. In addition, when wrapping napkins without pasting the release paper 5, as shown in FIG.
A packaging material 2 consisting of a release treatment layer 7 formed on one side of
is used. The film base material 6 is not particularly limited as long as it is flexible and can be coated with a mold release agent such as silicone, and examples of the material include a film made of polypropylene, low density polyethylene, linear low density polyethylene, etc. can be mentioned. The thickness of the base material 6 is 15-100μ, preferably 20-50μ. The mold release treatment layer 7 has a mold releasability with respect to the adhesive layer 4 provided on the napkin I, and comes into contact with the adhesive layer 4 during packaging. As the mold release treatment N7, for example, a mold release resin layer formed by applying silicone resin to the base material 6 using a gravure coating method or the like and curing it by irradiation or heating with electron beams, ultraviolet rays, etc., or other methods may be used. Examples include those constructed by directly kneading silicon into the base material 6.

In the present invention, when the napkin l is packaged by pasting the release paper 5 on the adhesive N4, 'i!' is placed on the packaging material so that the release paper 5 contacts the packaging material 2. It is preferable to wrap the product after it has been placed for one hour, so that there is no fear that the position of the peeled HJ 5 will shift due to external impact or the like. In addition, when packaging napkins without pasting the release paper 5 on the adhesive layer 4, a packaging material that has been subjected to a release treatment is used, and the adhesive layer 4 is in contact with the release treatment layer 7L of the packaging material. Place it in the 'R' position and then wrap it.

When opening the package according to method C of the present invention, after applying the tack seal 7 (or from the removable adhesive layer on the fixed side edges of the packaging material) 111, the packaging material 2 is unfolded. The package can be opened easily and the napkin 1 can be taken out. At this time, in the case of napkins packaged using a release-treated packaging material without affixing release paper, the adhesive layer 4 of the napkin can be easily peeled off from the packaging material 1 due to the releasability of the release-treated layer. do. Also, napkins with release paper pasted on them can be used after peeling off the release paper.
(A napkin packaged without a release paper attached has the adhesive layer 5 already exposed when it is removed from the packaging material 1, so it can be used immediately.

〔Effect of the invention〕

As explained above, the packaging method of the present invention simply and quickly wraps napkins by simply folding the packaging material and finally fixing the edges of the packaging material with a tack seal or a removable adhesive layer. This eliminates the need for the heat-sealing process that was essential in conventional packaging forms, making it possible to simplify the packaging process and reduce packaging costs compared to conventional methods. In addition, the napkin package packaged according to the present invention is easy to open, and since it does not have perforations, unlike conventional packaging forms, the perforations can be accidentally damaged and opened due to external impact. There is no risk of it happening.

In addition, the present invention uses a packaging material obtained by subjecting the adhesive layer of the napkin to a release treatment that has releasability.
To make it possible to package napkins without pasting release paper on the adhesive layer of the napkin, thereby eliminating the need for the work of pasting release paper and reducing the cost of products that do not require release paper. And you can save yourself the trouble of peeling off the release paper when using the napkin! It is also possible to eliminate the disposal problem of clogging the toilet bowl by disposing of the II# release paper in the toilet bowl.
