Description

[Detailed Description of the Invention] The present invention relates to the production of an enclosing bag with an opening/closing lid as a simple container for cosmetics, medicines, etc., particularly made by impregnating a sheet-like fiber material with a liquid or coating it with a powder. .

In recent years, disposable sanitary napkin-like products in which sheet-like fiber materials are impregnated with cosmetics, medicines, etc. have come into widespread use. Cosmetics are used for a wide variety of purposes, such as wiping off dirt, and medicines are used for disinfection, and there are also a wide variety of storage containers.

A bag-like simple enclosure with an opening/closing capacity has already been proposed as a storage container for loose napkins.

As a conventionally known enclosing bag with an opening/closing amount,
There is one disclosed in the No. 018 publication. According to the above publication, an inner lid part is formed on one side of the bag, a take-out port is provided in the middle part, an outer lid part is placed over the middle part, and the outer lid part is formed at the periphery of the outer lid part or Pressure-sensitive adhesive is applied only to the inner lid portion corresponding to the periphery so that it can be opened and closed repeatedly.

However, applying adhesive partially, combined with the fixing conditions of the lid, makes it extremely difficult to control dimensional accuracy.
This method is not practical due to the high cost.

In an enclosure bag with the structure described above, if pressure-sensitive adhesive is applied to the entire outer lid instead of applying adhesive partially, since the ejection opening is open, the contents inside and the lid can be separated. The pressure-sensitive adhesive in the container comes into direct contact with the outlet, and as a result, the adhesive may adhere to the contents, or the odor of the adhesive may transfer to the contents, resulting in deterioration of the quality of the contents or a foul odor. A point of weakness may occur during the process.

In addition, for bag-shaped products with opening/closing stands, we would like to have proof that the product is being used for the first time at the point of sale, in other words, that the consumer itself is not a used product, and once used, it cannot be returned to its original state. structure was desired.

The purpose of the present invention is to solve the above-mentioned problems, and to provide an enclosure bag that can be opened and closed repeatedly and a method for continuously manufacturing the enclosure bag, in which the adhesive on the opening/closing lid part does not affect the contents. It's about doing.

Another object is to provide a cosmetic packaging bag that has a sealing function and that allows consumers to feel confident that they are using it for the first time.

The present invention has achieved the above objects as follows.

The encapsulation bag for cosmetics of the present invention is an encapsulation bag formed of an airtight sheet material, and the encapsulation bag is provided with a cut-off portion for forming a take-out opening, and an opening/closing lid is formed. A pressure-sensitive adhesive layer is formed on almost the entire surface of one side of the film, and an opening/closing lid is enclosed so that the pressure-sensitive adhesive layer covers the notch. It is attached to the main body, and the enclosing bag is sealed with a wrapping paper containing decorative paper inside.

The method of the present invention also includes the step of making a cutting cut in the continuous sheet to form an opening for taking out the encapsulating bag;
A step of attaching the opening/closing amount formed with the pressure-sensitive adhesive (■) to the sheet so that the pressure-sensitive adhesive layer covers the area that will be the outlet, and On the opposite side, there are a step of placing a decorative paper over a place that will become an ejection opening, a step of wrapping the decorative paper with the sheet and fixing the opening in the longitudinal direction and the opening in the lateral direction of the sheet, and and cutting the sheet in the direction.

The tear-off notch to form the take-out opening of the encapsulation bag is intended to allow the consumer to open and close the opening amount and tear a portion of the encapsulation bag from the notch when the consumer uses the encapsulation bag for the first time. , for example, stamped in the form of perforations.

When a consumer uses an encapsulation bag for the first time, the part of the encapsulation bag that is torn from the cut (tear part) is stuck to the pressure-sensitive adhesive layer of the opening/closing volume, and the opening left by the cut part releases the contents. Serves as an outlet. When the opening/closing lid is closed, the cut-off part attached to the opening/closing amount opens the outlet exactly again.

Examples will be described below. As shown in the drawing, an airtight sheet material 1 is provided with closed-loop perforations in the shape of a circle, thin rectangle, ellipse, diamond, square, etc. at a location that will become the outlet 2 for the inclusion body using a press blade 1. Make 3 cuts.

Suitable sheet materials include single or composite materials of synthetic resin films such as polyethylene, polypropylene, polyester, polyamide, vinyl monocide, vinylidene chloride, cellophane, and acetate, or composite materials of these and aluminum foil.

A closure 15 having a pressure-sensitive adhesive layer is attached to the sheet using a suitable known labeling machine or manually so as to cover the cut portion 3 of the sheet obtained in the above step. In that case, the pressure sensitive adhesive layer and the sheet material are in contact. The opening/closing lid 5 is made of a film made of the same material as the sheet material or a similar material,
An adhesive layer is formed by coating one side of the adhesive with a pressure-sensitive adhesive made of acrylic acid ester, rubber, or the like. The opening 111 [5 has an appropriate shape such as a circle, an ellipse, a thin rectangle, a rhombus, or a square shape depending on the shape of the outlet.

One end 4 of the opening/closing lid 5 is fixed to the sheet 1 by an appropriate means such as heat sealing, frequency sealing, ultrasonic sealing, or adhesive, for example, with a heat sealer 13.

Synthetic or natural fiber paper on the sheet 1 rolled in the above step,
A decorative paper (such as a wet napkin) 14 impregnated with or coated with cosmetics, etc., is placed on woven fabric, non-woven fabric, cotton cloth, gauze, foam sheet, etc. In this case, the decorative paper is the opening/closing I1 of sheet 1.
Place 5 on the side opposite to the one on which it was fixed, above point 2, which will be the outlet.

That is, the decorative paper 14 is placed so that the opening/closing amount 5 is exposed in the finished product.

Next, use a regular single-bag machine to make a billow type bag □
do. For example, the sheet 1 is guided by the guide member 15 and the decorative paper is wrapped with the sheet 1. Then, by fixing both side edges of the sheet 1 to each other with a heat sealer 16, the opening in the longitudinal direction of the sheet is sealed to form a center seal part 6, and the opening in the lateral direction is sealed with a heat sealer 16.
The primary sheet sealed by 7 to form the end seal portion 7 is melt-cut at a fixed size using thermal power 18, and is then heavily packaged to obtain a product 19.

Since the enclosure bag of the present invention is manufactured as described above, the notch 3 has a sealing function at the time of initial use. In addition, a part of the sheet 1 separated from the notch 3 is
It is attached to the pressure-sensitive adhesive of the opening wJII5, and when the opening/closing amount is closed, it returns to its original position and tightly seals the outlet. Therefore, even when the cap is closed, the pressure sensitive adhesive does not affect the shape of the contents. Further, since the ejection opening is covered by both the portion of the separated sheet and the amount of opening/closing, the sealing performance is very good. Therefore, the liquid impregnated in the decorative paper will not evaporate even if it is opened and closed repeatedly or used for a long period of time with the opening/closing lid closed after one use. Furthermore, when the cut is made into a partially perforated cut portion instead of a closed loop cut portion, since the cut-off portion is connected to the encapsulation main body, there is an effect like an inner lid, and the application is further widened. In addition, since the cut-off part is connected to the enclosure main body, when the opening/closing amount is closed, the cut-off part will naturally return to its original position and open the ejection opening without having to fix one end of the opening/closing lid attached to it. block

According to the method of the present invention, it is possible to continuously produce convenient one-seal large bags of cosmetics as described above, and it is also economically advantageous.
