Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sterilization package.

[Prior Art] FIGS. 5 and 6 show a conventional sterile package.

First, as shown in FIG. 5, it is in the form of pillow packaging, in which a strip-shaped sterilized paper (22) is attached to the inside of the wrapping film (21) in the longitudinal direction of the sterilized paper, and a perforation is formed on the wrapping film. (23) is engraved. FIG. 6 shows an example of deep-drawing packaging, which is a container body (24) made of a plastic molded product.
The contents to be sterilized are contained in a container consisting of a lid (25) made of sterilized paper.

[Problems to be solved by the invention]

However, when accommodating medical instruments such as injection needles and syringes, the contents cannot be fixed in pillow packaging and move, so glass products such as syringes are used during sterilization or transportation of the contents. The package may be broken or the package may be broken by a sharp-pointed object such as an injection needle. Even in deep-drawing packaging, as with pillow packaging, the contents cannot be fixed, so glass products may crack, and since the bottom material is heated and vacuum-molded, the corners of the bottom material tend to become thin. Since molding aptitude is required, the packaging material cost tends to be high. Further, the printability was poor, and it was difficult to obtain a barrier property equivalent to that of an aluminum foil.

Therefore, a problem to be solved by the present invention is to provide a tray-shaped deformed four-sided seal package capable of fixing the contents and enabling high-barrier packaging at low cost.

[Means for solving problems]

The present invention solves the above-mentioned problems by saying, "On a container main body consisting of a molding part which is recessed in a shape corresponding to the cross-sectional shape of the contents to be sterilized and non-molding parts along both sides of the molding part. ,
A heat-shrinkable film having slits formed thereon is heat-bonded at a non-molding portion to a lid body to which a sheet having air permeability and bacteria impermeability is attached so as to cover at least the slit portions. The slit portion of the lid is contracted and opened, and both front and rear ends of the opened container body are gusset-folded, and the container body surface and the lid surface are in contact with each other, and the container is folded in a pleated shape. A sterilized package in which the body surfaces are bonded together. ] Is the gist.

Thus, in the present invention, the sheet having air permeability and bacteria impermeability does not include substances that react with EOG such as amino groups, -SH groups, and carboxyl groups, and volatile substances such as mercaptans and esters, In addition, a material that is strong in strength and does not break during sterilization can be applied, and for example, uncoated paper, non-woven fabric, Japanese paper, sterilized paper, etc. can be used.

[Action]

The above-mentioned sterilized package prevents damage to the contents to be sterilized or transportation of the contents, and prevents the sterilized package itself from breaking.

〔Example〕

FIG. 5 shows the package of the present invention shown in FIGS. First
FIG. 1 is a perspective view showing the external appearance of the package, FIG. 2 is a sectional view taken along the line AA ′ of FIG. 1, and FIG. 3 is B- of the first illustration.
FIG. 4 is a sectional view taken along the line B'of FIG. 4, and FIG. 4 is a sectional view taken along the line CC 'of FIG. It is composed of a soft packaging material, which is composed of a molded part (7a) recessed into a shape corresponding to the cross-sectional shape of the rectangular parallelepiped-shaped content (5) and non-molded parts (7b) along both sides of the molded part. The contents are arranged in the molding part of the container body (7). Then, a lid (6) made of a heat-shrinkable film is arranged on the container body in which the contents are stored, and the non-molded portion and the lid surface area that is in contact with the non-molded portion are bonded to each other. The front and rear ends of the opened container body are gusset-folded, and the surfaces of the container body molding portion and the lid surface that are in contact with each other and the molding portion surfaces of the container body folded in a pleated shape are bonded.

A slit (11) is engraved in the center of the lid (6) in a direction corresponding to the short width direction of the content, and covers the slit engraved portion. A band-shaped sterilized paper (12) is laminated on a partial region of the lid.

Further, since the heat shrinkable raw film forming the lid body (6) shrinks due to the sealing heat, the slit portion which is not sealed is opened,
The ventilation area is large. In the figure, (8) (9)
Is a seal portion, and (10) is a folded seal portion.

[Effect of device]

As described in detail above, since the sterilized package of the present invention can be tightly packaged according to the cross-sectional shape of the content, the content to be sterilized can be compared with conventional pillow packaging and deep drawing packaging. Can be fixed, and damage of the contents and breakage of the package itself can be prevented during transportation or sterilization. Moreover, since a general laminate material can be used as the material of the container body, printing can be easily performed on the container body. Furthermore, by using an aluminum foil having a thickness of about 7 to 9 μm as a barrier layer material, a high barrier sterilized package can be obtained.
