The front zipper is closed and the bag opening is heat-sealed, and if necessary, the front and rear sides of the bag body are welded to the inner side of the zipper and at appropriate locations in the length direction. The package is characterized by a point seal that reinforces the latch strength of the surface fastener. (Claim 16),

(1) The packaging bag having the draining function according to any one of claims 1 to 14 and the packaging body according to any one of claims 15 and 16 may tear and open the vicinity of the outside of the surface fastener when eating food. Therefore, there is a common effect that draining can be performed with a simple operation by simply turning the bag upside down. In the present invention, for medium bags and large bags, a point seal is applied to the vicinity of the inside of the surface fastener to reinforce the latch strength. Therefore, the surface fastener may open and the food in the contents may pop out when draining. Absent.
In the present invention, even if the bag is inflated and the laminated film is bent at the time of heat sealing, a gap between labyrinths of the surface fastener is secured, so that a drainage passage for draining is secured and draining can be performed in a short time. Therefore, when the bag with the draining function of Patent Document 1 (Japanese Patent Application Laid-Open No. 11-147542) has, the liquid passage for draining is configured as a non-seal part, and the bag swells In the case of heat sealing, the problem that the bent film is bent in the laminated film and the liquid passage for draining water is blocked is eliminated in the present invention, and the water draining function is superior to the conventional product. ing.
(2) The packaging bag having a draining function according to claims 1 to 11 and the package thereof have resealability because the surface fastener is provided so as to have a length substantially equal to the entire length of one side of the bag. ing. That is, when the entire amount of food is consumed at once, the sheet fastener can be opened and a necessary amount of drained food can be taken out from this, and the sheet fastener can be closed and finished with the rest drained. On the other hand, when the entire amount of food is consumed at one time, there is no need for resealing, so that the entire amount of the food that has been cut off from one side avoiding the surface fastener and drained can be taken out. Therefore, the pair of male surface fasteners of the packaging bag having a draining function according to claims 1 to 11 and the package thereof is a combination of a male surface fastener and a female surface fastener, Alternatively, a combination of a male surface fastener and a male surface fastener may be used.
The packaging bag having a draining function according to claim 12 and its package are limited to the use of a pair of male surface fasteners, and are suitable for bags that require resealability because they are consumed in small amounts at a time. It is. This is due to the following reason.
In a combination of a male surface fastener and a female surface fastener, when the fastener is repeatedly fitted and detached many times, the loop ends of the female surface fastener are cut off to generate fine dust. Although there is a possibility of mixing with the drained food, the combination of the male surface fastener and the male surface fastener does not generate such fine dust and ensures food safety.
A packaging bag having a draining function according to claims 1 to 11 and a packaging body thereof having no point seal are suitable for small bags. Specifically, for example, it is suitable for a small bag having an internal volume of about 700 mm liter or less and a bag width of about 130 mm or less. The surface fastener disperses and bears the force of opening the fastener as compared with the linear fastener, so when the internal volume is about 700 mm liter, the bag width may be opened by the pressure of the contents up to about 130 mm. There is no. If a hole is made in the linear fastener so as to have a draining function, the force to open the fastener is concentrated, and once it is opened, it opens all over the length.
Moreover, the packaging bag which has the draining function of Claims 1 thru | or 11, and its packaging body, Comprising: A point seal is provided for medium bags and large bags. Specifically, for example, it is suitable for a small bag having an internal volume of about 700 mm liters or more and a bag width of about 130 mm or more.
If the latch strength of the planar fastener is increased, the packaging bag of the present invention can be applied to an inner bag or a large bag without providing a point seal. Therefore, when attaching a planar fastener having an appropriate latch strength, the invention of claim 3 is effective and preferable.
The packaging bag having a draining function according to claims 13 and 14 and the package thereof have a short pair of male surface fasteners, and therefore need not have a resealing function regardless of whether for a small bag, a medium bag, or a large bag. Suitable for bags.

DESCRIPTION OF EMBODIMENTS Embodiments of a packaging bag and a packaging body having a draining function of the present invention will be described with reference to the drawings.
First, a packaging bag having a draining function and a package will be described with reference to FIG. (See claims 1, 3, 4),
The packaging bag P1 having a draining function according to the first embodiment has a bag body 1 that is a three-sided seal bag and a pair of planar fasteners 2 bonded to the upper part inside the bag body 1. . The bag body 1 is formed by forming a front surface portion 1a and a rear surface portion 1b with a rectangular laminated packaging material so as to have water-proofing properties, and the inner surface is a resin film having heat sealability, and the inner surfaces are overlapped to form side seals 1c, 1d. And top seal 1e. (See claim 4)
Since this package P1 is a type in which an opening for storing water-removed food is secured with the lower edge of the bag avoiding the surface fastener 2 being unsealed, a pouch that does not require the point seal 3 is provided. For medium bags and for large bags where the point seal 3 needs to be provided.
The bag body 1 is provided with notches 1f and 1g at the upper and lower portions of the side seals 1c and 1d. The notch 1f is used to cut a gap between the top seal 1e and the pair of planar fasteners 2 when eating food, and the notch 1g is used to cut the food after draining from the bag bottom. Is. The notch 1g may be provided slightly below the planar fastener 2. When resealability is required, the notch 1g is not provided.
The pair of planar fasteners 2 are inserted and attached to the upper part inside the bag body 1 before applying the side seals 1c, 1d and the top seal 1e.
The pair of planar fasteners 2 may be either a male-female fitting type (hook / loop fitting type) fastener or a male-male fitting type (hook / hook fitting type) fastener. From the following points, a male-male fitting type is preferably used.
The male surface fastener is formed with an extrusion machine after forming a base part and several ridges protruding on one side of the base part, and then gives incisions that are finely interrupted to each ridge part in-line. Next, the base portion is stretched by a roller to provide a gap at the cut portion where the ridge portion is finely interrupted, and the protrusions for latching are manufactured in a state where they are arranged in a plurality of rows. The hooking protrusion of the surface fastener of the mold can be fitted between the other hooking protrusion gaps.
If the pair of planar fasteners 2 is a male-female fitting type, when the fastener is opened, the loop is broken by the hook and fine dust may be generated and mixed into food. It is preferable to limit to a male-male fitting type fastener that does not have this.
Since the pair of planar fasteners 2 are made of polypropylene or polyethylene and are not sufficiently stretched, the pair of planar fasteners 2 has heat sealability, and directly heat seals the outer surface of the base portion to the inner surface of the bag body 1. be able to. However, it is necessary to match the material of the inner surface of the bag body 1 with the material of the planar fastener 2.
The surface fastener 2 is attached to the inner surface of the bag body 1 because the protrusions are dispersed and will not buckle even if a sealing force is applied, so it will buckle immediately with a small sealing force and insert a spacer inside. Compared to a linear fastener that needs to be heat sealed, the outer surface of the base portion can be directly heat sealed to the inner surface of the bag body P1.
The pair of planar fasteners 2 are attached to the bag body 1 so that the opening at the upper end of the bag is long enough to be secured. That is, the pair of planar fasteners 2 are provided with the full bag width. In the figure, both end portions of the pair of planar fasteners 2 are stopped at the inner end without intersecting the seal portions on both side edges of the bag body. This invention is not limited to this, The case where the both ends of a pair of planar fastener 2 are integrally sealed by the state which was pinched | interposed and sealed by the seal part of the both-sides edge of a bag main body is included.
The point seal 3 welds the front surface portion and the rear surface portion of the bag body at the inner side of the surface fastener 2 and in the middle of the length direction, and serves to reinforce the latch strength of the surface fastener. Fulfill. Whether the point seal 3 is necessary or not can be correlated with the latch strength of the pair of planar fasteners 2, the bag width (the length of the pair of planar fasteners 2), and the internal volume.
The packaging body using the packaging bag having a draining function of this embodiment is one in which the packaging body P1 shown in FIG. . (See claim 15),
In order to drain and eat the packaged drained food, the upper end of the bag is cut open so as to connect the other notch 1f to the other notch 1f, and the package is turned upside down. Then, the pair of planar fasteners 2 are engaged with each other with a labyrinth gap, and only water is discharged through the labyrinth gap because it does not open.
When draining is finished, if resealability is not necessary, the bag is opened from the notch 1g to remove the whole amount of food, or if resealability is required, the bag is opened from the notch 1g. The bag is turned upside down and the pair of planar fasteners 2 are opened widely, a necessary amount of food is taken out, the pair of planar fasteners 2 is closed, and the rest is left drained. .
In the middle bag and the large bag provided with the point seal 3, the pair of planar fasteners 2 are opened, and further, the point seal 3 is opened so that the front portion and the rear portion of the bag body are not torn. For this reason, the point seal 3 is not a very strong heat seal.
