Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, by providing a band-shaped engaging tool (fitting tool) composed of a male member and a female member in an opening portion of a bag,
Openable and closable bags (chuck bags) are used in many fields such as foods, pharmaceuticals and sundries. Here, the male member is
A band-shaped base portion welded to the bag inner surface portion near the opening by heat sealing or the like, a male bite portion projecting from the band-shaped base portion, and having a cross section where the tip bulges and extending along the extending direction of the band-shaped base portion, It is comprised including.

[0003] Similarly, the female member includes a band-shaped base portion and a female bite portion extending along the extending direction of the band-shaped base portion with a curved cross-section that engages with the tip bulging portion of the male bite portion. You. Then, by engaging the male bite portion and the female bite portion with each other, the periphery of the bag opening is linearly sealed, so that the food and the like can be hermetically stored without leaking. Conventionally, when taking out the contents of food or the like that is hermetically stored in such a bag with an occlusal tool, it is conventionally grasped by pulling the outer portion of the bag near the opening and pulling it open, or by inserting a finger into the opening of the bag and engaging the occlusal portion. Was pushed open.

[0004]

However, when trying to open the bag by pulling the outer portion of the bag, the force of the hand acts on the entire jig, so that the bag cannot be opened without pulling with a strong force. There is. Also,
If a finger is inserted into the opening of the bag to push it open, there is a problem that it is difficult to apply force and that the finger easily touches the contents. In this case, it is conceivable to form a rib on the opening side of the jig and hook a finger on the rib to open it.However, a sufficient height is required to hook the finger sufficiently, and the contents are exposed. There is a problem that it may be an obstacle to putting. In addition, there is a problem in that the ribs are crushed when the jig is heat-sealed to the inner surface of the bag, and the desired function cannot be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an easy-to-use zipper with a zipper with which a finger is put into a zipper-containing packaging bag and the bag is opened. And a packaging bag with an articulation tool.

[0006]

In order to achieve the above object, the present invention provides an articulating tool comprising an engaging male member and a female member, wherein at least one of the male member and the female member is engaged. Or, a band-shaped base that adheres to the inner surface of the bag in which the occlusal tool is used, an occlusal portion that projects from the band-shaped base and achieves male and female occlusion, and is formed on the same plane as the occlusal portion, And an inclined rib.

Here, the band-shaped base means a plate-shaped portion. In addition, an occlusal portion and a rib are formed in the same band on the band-shaped base. The occlusal portion is different in shape between the male member and the female member. In the case of a male member, for example, its shape is a heart-shaped cross section, and in the case of a female member, for example, its shape is a circular cross section. It is arc-shaped. The occlusal portion of the male member and the occlusal portion of the female member are engaged with each other.

Further, the rib is a portion protruding from the band-shaped base, and the shape of the end is rounded,
It may be square.

[0009] The male member and the female member are paired to form the jaw of the present invention. This jaw is manufactured by extrusion molding using a mold. Also, the material of this articulation tool can adopt polyolefin, for example, LLDPE
(Linear low density polyethylene), LDPE (low density polyethylene), PP (polypropylene) and the like.

According to the present invention, since the rib is inclined toward the occlusal portion, the resistance to the finger is increased, so that the finger can be properly caught on the rib. Put your finger on the attached packaging bag and open the bag.
Opening can be facilitated. In addition, when a jaw provided with ribs is fused to a bag, a single rib is used, so that a portion without ribs becomes large. Can be. further,
Since the rib and the bite part are formed in one bite,
Since it is only necessary to fuse at one place when fusing to a bag, compared to a packaging bag with a jaw having a rib and an occlusion part on another surface, it is possible to use a jig that is easier to manufacture. it can.

In the above, either of the number of the ribs of the male member and the number of the female member may be one, but the number of the ribs of the male member and the number of the female member is one. More preferably a book. According to this, if the number of the ribs of the male member and the female member is one each, when opening the bag with the jaw tool, both the right and left fingers are caught by the ribs. Can open the bag with less force.

Preferably, the rib is formed such that when the male member and the female member are engaged with each other, the respective ribs are shifted from each other. According to this, when the male member and the female member are engaged with each other, the ribs of the male member and the female member are formed so that the respective ribs are shifted from each other. Since the ribs do not hit each other when they are fitted, the rib portion of the bag with the jaw does not bulge. In addition, when the ribs collide with each other, a force is applied in a direction in which the occlusal portion of the occlusal tool separates, so that the occlusal portion of the occlusal portion may be released, and a problem may occur in the sealing performance. Therefore, when the male member and the female member are overlapped, the respective ribs do not hit each other, so that there is no problem in the sealing performance.

In the above, it is preferable that the angle formed by the rib on the side of the occlusion part and the band-shaped base is 30 to 80 degrees. If the angle between the rib and the band-shaped base is less than 30 degrees, the portion where the finger is caught by the rib is reduced, and the finger may not be caught by the rib in some cases. Also, when the angle between the rib and the band-shaped base is larger than 80 degrees, the portion where the finger gets caught on the rib becomes large,
Since the force supported by the rib in the hooking direction is reduced, a great force may be required when the finger is hooked on the rib. Therefore, if the angle formed between the rib and the band-shaped base is 30 to 80 degrees, it is possible to improve the catch of the finger on the rib.

Further, the height of the rib is 0.3 to 1.2.
mm. Rib height is 0.3mm
If the value is less than the predetermined value, the portion where the finger is caught on the rib is reduced, and the finger may not be caught on the rib in some cases. Further, when the height of the rib is larger than 1.2 mm, the portion where the finger is hooked on the rib becomes large, but the force of the rib supporting in the hooking direction becomes small.
A great deal of force may have to be applied when hooking a finger on the rib. Therefore, when the height of the rib is 0.3
If it is 1.2 mm, it is possible to improve the catch of the finger on the rib.

[0015] The packaging bag with a zipper of the present invention is characterized in that the above-mentioned zipper is fused to the inner surface of the bag.
Here, as the bag of the packaging bag with the occlusal tool, a sheet having either a single-layer structure of only the base material layer or a two-layer structure including the base material layer and the sealant layer fused to the occlusal tool is used. Can be used.

As the material of the base layer, PET (polyethylene terephthalate), NY (nylon), CPP (cast polypropylene), or the like can be used. As the material of the sealant layer, if it is the same material as the articulator, it is easy to fuse, so polyolefin is preferable,
For example, LLDPE (linear low density polyethylene), L
DPE (low density polyethylene), PP (polypropylene) and the like.

As a method for producing a sheet to be a bag, a known method such as a casting method, a melt extrusion method, and a calendar method can be employed for the sheet to be a base material layer. In the case of manufacturing a two-layer sheet, as described above, after forming the base layer sheet, the sealant is formed on the base layer sheet by a known method such as extrusion lamination or dry lamination. The layers to be layers are stacked.

An occlusal tool is fused to the single-layered sheet or the two-layered sheet obtained as described above by a method such as heat sealing. Specifically, for example, the jig is heat-sealed to two rectangular sheets so that the jig is on the inner surface of the bag. At this time, the jaws are fused to a side closer to one side of the sheet, and the other three sides are fused by heat sealing, so that the two rectangular sheets become bag-like.

According to the present invention, since the above-described jaw is fused to the inner surface of the bag, the jaw is provided with the rib. With a small force,
Since the bag can be opened, it is easy to open. Also,
When putting the finger into the bag where the above-mentioned jaw tool is fused and opening it, the rib hits the finger before the bite part, and the finger is hooked on the rib to open the bag, so that the contents of the bag must be touched. Nor. Furthermore, using the ribs of the above-mentioned jaw tool,
Since the bag can be opened with a small force, the bag can be opened even if the occlusal force of the occlusal portion is strong, so that a bag with good airtightness can be obtained.

In the above, the rib of the jig is located closer to the opening of the bag than the occlusion part, and the rib is
Preferably, it faces the inner surface of the bag. According to this, since the rib of the jaw is located closer to the opening of the bag than the bite, the finger is inserted from the opening of the bag sealed by the bite, and when the bag is opened, the finger is opened. Hits the rib first, and because the rib faces the inner surface of the bag, you can hook your finger on the rib, so just insert your finger into the opening of the bag and open the bag with a small force be able to.

<Sensory Survey> Examples 1 to 7, Comparative Examples 1 and 2
When opening the manufactured packaging bag 2 under the conditions described in the above, the feeling of catching a finger was examined. The results are shown in Table 1.

[0044]

[Table 1]

The meanings of the symbols shown in Table 1 are as follows. ○ indicates that the finger is easily caught.
In the case of △, the finger is usually caught. Furthermore, ×
Does not catch the finger. According to Table 1, since Example 1 has a rib of 50 degrees, compared to the case of Comparative Examples 1 and 2 where the angle of the rib is 90 degrees or no rib, the finger is caught. Is good. In Examples 2 and 3, since the angle of the rib is 30 to 80 degrees, it can be seen that the finger catch is very good. In Examples 4 and 5, since the height of the rib is 0.3 to 1.2 mm, it can be seen that the finger is very good at catching. In Example 6, since the angle of the rib was 20 degrees, it was found that the finger was good for catching. In Example 7, since the height of the rib is 0.1 mm, it can be seen that the finger is easily caught.

[0046]

According to the present invention, since the rib is inclined toward the occlusion portion, the resistance to the finger increases, so that it is possible to improve the catch of the finger on the rib. In addition, when a jaw provided with ribs is fused to a bag, a single rib is used, so that a portion without ribs becomes large. Can be. In addition, since the rib and the occlusal part are formed in one occlusal tool, it is only necessary to fuse it at one place when fusing to the bag. As compared with the packaging bag, it is possible to provide a jig which can be easily manufactured. And since the rib of the jaw tool is located on the opening side of the bag rather than the occlusion portion, a finger is inserted from the opening side of the bag sealed by the occlusion portion, and when the bag is opened, the finger comes first. Because the rib hits the rib and faces the inner surface of the bag, a finger can be hooked on the rib, so the bag can be opened with only a small force by inserting the finger into the opening of the bag. .
