Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bag for containing primarily powdered or granular articles, such as electroacoustic feed such as dog food, and foods such as flour.

This type of bag, especially paper packaging bags, usually has a bag opening sealed by pasting or sewing, and can be opened by tearing the bag opening or pulling out the sewing thread when in use. There is.

Therefore, once opened, there is no means to close the bag, and the bag has no choice but to close by folding the bag opening or tying it with string.

Therefore, not only is it extremely troublesome to operate feeds and foods that are used on a daily basis, but it is also difficult to seal the seal completely, allowing moisture to easily enter, resulting in the generation of odors, especially in dog food.

In order to solve the above-mentioned problems, it is conceivable to provide the bag opening with a zipper that can be opened and closed, such as a slide zipper or a velvet type zipper.

However, simply providing a zipper will not prevent moisture from entering when stored for a long time, and furthermore, items may leak from part of the zipper during storage or transportation, or they may adhere to the area around the zipper and interfere with opening and closing. Easy to do.

The present invention was developed with the above-mentioned points in mind, and by providing a zipper and chain stitching means in parallel at the bag opening, it is possible to prevent moisture during storage and transportation, and to prevent articles from adhering to the zipper. To provide a bag which can be easily opened and closed with a zipper even after the chain stitch is untied, and which is convenient for use.

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

Reference numeral 1 denotes a bag containing a powder or granular article 2, and a slide fastener 4 is attached to the peripheral edge of the bag opening 3, so that the bag opening 3 can be opened and closed by a slider 5.

Near the bottom of the slide fastener 4, a sewn part 6 is formed parallel to the slide fastener 4 by single chain stitch or double chain stitch, thereby completely separating the bag opening part 3 and the article storage part I. has been done.

In this state, the article is stored, transported, or sold, and when used, the sewing thread of the sewn portion 6 is untied, and then the bag opening portion 3 is opened and closed by operating the slide fastener 4 for use.

Although the slide fastener 4 is used in the above embodiment,
Instead, any of a velvet type fastener, a snap button type fastener, a rail type fastener, etc. may be used.

The sewn portion 6 may be formed after the articles are placed in the bag 1, or may be formed before the articles are placed in the bag 1.

In the former case, the item is placed in a bag 1 with a zipper 4 and then sewn.

In the latter case, as shown in FIG. 3, the bottom side 1a (left and right sides 1b or 1c may be used) of the bag 1 is opened, the article is put in through this opening 8, and then the opening 8 is sealed. Just do it.

As described above, according to the present invention, a zipper is provided at the bag opening and a sewn portion is formed near the zipper.
Even after the seams are untied, the bag opening can be easily opened and closed using the zipper, which is effective in preventing moisture and makes it convenient to use.Moreover, because of the seams, the items are completely sealed.
Since there is no risk of the item becoming damp or sticking to the zipper during storage or transportation, and the pressure of the item is not directly applied to the zipper, the zipper does not require as much strength and can therefore be disposable. There are various effects such as being able to use inexpensive fasteners such as slide fasteners using nonwoven fabric or vinyl for the tape and aluminum for the fasteners.

The bag of the present invention is effective for packaging powdered or granular items, but it can also be used for items of other shapes, and can also be used for electrolyzed feed, food, and cement bags, etc. It can be used regardless of the type of item.

The material of the sub-lease may be any material such as paper, cloth, synthetic resin, etc.
