Abstract

PROBLEM TO BE SOLVED: To provide a packaging bag having a concavo-convex meshing fastener made of plastic material that can be opened or closed in which a releasing of the fastener can be carried out efficiently and in a sanitary manner without making direct touch with a finger at an upper opening edge. SOLUTION: An upper opening of a packaging bag 1 is used as a pouring port 3. A fastener 2 for opening or closing the bag is arranged below the pouring port 3. A releasing piece 4 of the fastener 2 is formed from above this fastener 2 toward an outward direction of the pouring port. An extending part 8 is arranged above a part acting as the pouring port 3. After some stored items are stored in the bag 1, the fastener 2 is closed and the upper part of the extending part 8 is sealed 9, so that the stored items can be sealingly closed. The lower part of the seal 9 is cut and removed to form the pouring port 3, and releasing piece 4 is picked with fingers to be pulled in a lateral direction, so that the fastener can be released without touching the pouring port 3 with a hand.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag, and more particularly to a packaging bag with a fastener.

[0002]

2. Description of the Related Art Conventionally, an insect repellent for clothing such as naphthalene or cerebrum is sealed in a packaging bag. And the like, the opening edge 44 of the bag is pinched, and a concave-convex engagement type fastener-4 formed of lower plastic is used.
Open 5 and take out the required number of insect repellents. After being taken out, the fastener 45 is closed and sealed with a finger from the outside while being squeezed with a finger to prevent sublimation of the insect repellent. Further, when it becomes necessary to use the insect repellent again, the user opens the fastener 45 by picking the opening edge 44 of the bag and pulling the bag left and right to take out the stored insect repellent.
(FIGS. 6 and 7)

In the case of an article such as the insect repellent, the bag 4
There is no inconvenience even if the fastener 45 is opened by directly picking the opening edge 44 with a finger. However, when milk, juice, coffee and other liquid foods are stored in the packaging bag, the opening edge 44 serves as a spout when removing the stored items. Food will pass through it. Therefore, it is not preferable in terms of hygiene to open the fastener 45 by directly picking the opening edge 44 with a finger.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a fastener capable of opening a fastener efficiently and hygienically without directly touching an opening edge of a packaging bag. .

[0005]

According to the present invention, a spout is provided at an upper opening of a packaging bag, and a fastener is provided below the spout so that the bag can be opened and closed, and the spout is provided from above the fastener. An open piece of the fastener is formed toward the outside of the fastener.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A fastener-2 is provided on the inner surface of the upper part of the packaging bag 1, and the bag can be sealed and opened / closed by the fastener. The upper part of the bag 1 is opened, and serves as a spout 3 for taking out the one stored in the packaging bag. Above the fastener-2, there is formed an open piece 4 of the fastener-2 extending outward from the spout 3. 1 to 3 form the open piece 4 by folding the bag piece at the upper part of the fastener-2 into the inner surface side, and the open piece 4 is in a folded double state. The portion near the fastener is bonded 5 by welding or the like.

The bottom of the packaging bag 1 can be formed in an appropriate shape according to the articles to be stored. In the illustrated case, a gusset piece 6 is inserted into the bottom to form a substantially bowl-shaped seal 7. When an object is stored in the bag, the gusset piece 6 is opened, and the bottom becomes substantially spindle-shaped. This allows the bag to be kept upright.

[0008] When actually storing items in the packaging bag, an extension portion 8 integrally extending from the opening serving as the above-described spout 3 is provided, and the fastener-2 is attached. When the bag is filled with milk, juice, coffee, tomato juice and other liquids in the opened state, the bottom gusset 6 is opened and stored, and the fastener 2 is closed. When the upper portion of the extension 8 is sealed 9, the stored items are sealed in the packaging bag. In this state, the packaging bag can be set up for transportation, sale, and the like.

When taking out the contents stored in the bag, the extension portion 8
The lower part 10 of the seal 9 is cut with scissors or the like and removed to form the spout 3. And when the above-mentioned open piece 4 is pinched and pulled to the right and left, the fasteners 2 meshed with each other.
Is opened, so that the stored contents can be taken out from the spout 3 while tilting the packaging bag. (Fig. 3) When the amount of stored items is large, the stored items remain inside, so if you hold down the fastener-2 while pressing it hard from the outside,
Since the fastener-2 can be closed, it can be stored in a refrigerator or the like in that state until the next use. Then, when taking out the stored item again, if the fastener 2 is opened by pulling the open piece 4 in the same manner as above, the stored item can be taken out hygienically.

FIG. 4 shows an example in which the upper portion of the packaging bag 1 is folded back outward, and the upper portion of the packaging bag 1 is appropriately glued 5 above the fastener 2, and after the contents are stored in the bag, the extension portion 8 is sealed. 9 If the lower part 10 of the seal 9 is cut and removed, the spout 3 and the open piece 4 are formed, so that the fastener 2 can be opened with the open piece 4.

A packaging bag 1 shown in FIG. 5 is provided with a spout 3 by turning the upper part of the bag outward and bonding it appropriately 5 above the fastener 2 and then turning it up again, so as to be above the spout 3. The extended portion 8 is formed up to. After the stored items are stored in the bag, the extension portion 8 is sealed 9. When the lower part of the seal 9 is cut and removed, the spout 3 appears and is formed, and the open piece 4 is formed.

The opening piece may be formed so as to project outward from the upper portion as close as possible to the fastener, so that the fastener can be easily opened with a smaller action. Also, this open piece can be formed not on the entire length of the fastener but on a part thereof. In this case,
Usually, it is often good to provide it at the center of the fastener. The open piece can be formed not by folding as described above, but by attaching another piece from outside. Although the upper and lower expressions are used in the specification, they are for convenience of explanation and do not mean an absolute upper and lower relationship.

[0013]

According to the present invention, as described above, the fastener can be opened and closed without directly touching the spout of the bag by the open piece, so that the stored items can be taken out or stored in a sanitary manner. The fastener can be easily opened and closed, and can be widely used as a storage bag for not only the above-mentioned liquid or paste-like material but also a solid-mixed one or a solid-containing one.
