Description

The present invention relates to a package for packaging one or more disposable diapers, sanitary napkins and the like.

One or a plurality of articles such as disposable diapers and sanitary napkins are sold in a package, and the package is formed of a film made of a thermoplastic synthetic resin. (Patent Document 1)

The package body has a cylindrical shape, and a space for storing an article is formed therein, and the openings at both ends thereof are sealed by heat sealing or the like.
Japanese Patent Application Laid-Open No. 2005-178827

The package disclosed in Patent Document 1 is entirely formed of a thermoplastic synthetic resin film, and the synthetic resin film uses a relatively thick film to give strength, and the material cost is high. Has the problem. Moreover, since petroleum raw materials are used, there is a problem in terms of resource saving.

An object of the present invention is to provide a package that reduces costs and contributes to resource saving.

In order to solve the above-mentioned problems, the package of the present invention has a cylindrical shape, a main part in which a space for storing an article is formed, and both ends of the main part are attached to the opening. In the package including a sealing portion to be sealed, the main body is formed of a paper material, and the sealing portion is formed of a thermoplastic resin film.

According to the present invention, since the main part is formed of paper, the material cost can be reduced. Moreover, the resin film portion can be reduced, and resources can be saved.

In the package of the present invention, it is preferable that the paper material is a waste paper.
According to this aspect, it is possible to further save resources.

In the package of this invention, it is preferable that a sealing part is sealed by heat sealing | fusion.
According to this aspect, the packaging process can be executed during the article production line, and it is possible to cope with mass production.

In the package of the present invention, it is preferable that the surface of the main body is subjected to waterproofing or water repellent treatment.
According to this aspect, it is possible to prevent moisture from penetrating into the internal article due to scattering of water from the outside, and the quality of the article can be protected.

The invention will be more clearly understood from the following description of preferred embodiments with reference to the accompanying drawings, in which: However, the examples and figures are for illustration and description only and should not be used to define the scope of the present invention. The scope of the present invention is defined only by the claims. In the accompanying drawings, the same part numbers in a plurality of drawings indicate the same or corresponding parts.

Example 1:
Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the unfolded state of the package.

The package 1 includes a main part 2 and a pair of sealing parts 3 and 3 disposed at both ends thereof. The main body portion 2 and the sealing portions 3 and 3 are joined at the joining portions 4 and 4 by a known means such as an adhesive or heat seal. The joining parts 4 and 4 may be joined so that the main part 2 and the sealing parts 3 and 3 can be separated in order to facilitate separation when the packaging body 1 is discarded.

The main body 2 is made of a paper material. This paper material may be a waste paper recycled as a raw material. Thereby, use of a synthetic resin material can be reduced, cost can be reduced and resources can be saved.
Further, one surface of the main body 2 may be subjected to water repellent treatment or waterproof treatment.
Thereby, the articles | goods packaged by the package 1 can be protected from scattering of the water from the outside.

The sealing portions 3 and 3 are formed of a thermoplastic resin film such as a polyester synthetic resin, a polyacrylonitrile synthetic resin, a polyvinyl chloride synthetic resin, a polyethylene synthetic resin, a polypropylene synthetic resin, or a polystyrene synthetic resin. Thus, the sealing portions 3 and 3 can be sealed by known heat fusion means such as heat sealing and sonic sealing.

FIG. 2 shows the external appearance of the package 1 in a state where articles are stored inside.

The package 1 is deformed into a substantially cylindrical shape so that the sealing portions 3 and 3 are positioned so as to cover and face the opening of the main body 2, and a space S for storing the article A is provided in the main body 2. It is formed. One or more articles A may be accommodated in the space S.
In addition, a pattern or other display for understanding the contents of the stored article A may be printed on the outer surface of the main body 2.

Article A is a disposable diaper or sanitary napkin, and has a known configuration in which an absorbent for absorbing urine and menstrual blood is sandwiched between a liquid-permeable top sheet and a liquid-impermeable back sheet. A is stored in a folded state.

Each of the sealing portions 3 and 3 is disposed so as to cover the opening of the main body portion 2 and is sealed by thermal fusion at the fusion portions 5 and 5 at the end opposite to the joint portion 4 to the main body portion 2. Yes. Since the sealing process of the sealing parts 3 and 3 is performed by heat fusion, it can be executed in-line, that is, as a part of the manufacturing process of the article A.
Thereby, it can respond to mass production.

In this case, the main body 2 and the sealing portions 3 and 3 may be supplied to the production line in a state of being joined in advance, or may be joined on the production line. When the main body 2 and the sealing portions 3 and 3 are supplied in a state of being bonded in advance, a material in which the sealing portions 3 and 3 are bonded to both sides in the width direction of the original roll is used. Further, when the main body 2 and the sealing portions 3 and 3 are joined on the production line, the sealing portion 3 for the main body 2 is fed on both sides in the width direction of the main body 2 web supplied from the raw material of the main body 2. A step of joining the web is included.

When sealing the sealing parts 3 and 3, you may form the gusset 6 in the side part of a package. Moreover, the sealing parts 3 and 3 may be a transparent film, may be opaque, and the design may be printed appropriately. Further, the sealing portions 3 and 3 may be formed with breakage portions such as perforations for easy opening.

The present invention can be applied, for example, as a package for disposable diapers and sanitary napkins.

It is an expanded view of the package body concerning the Example of this invention. It is a figure which shows the state which packaged the articles | goods with the package concerning the Example of this invention.
