Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a bag-bound product bundling package and a packaging method for breads in which an opening of a packaging bag containing breads is bundled with a bundling tool so that it can be repeatedly opened and closed.
[0002]
[Prior art]
When packaging bread such as bread and bread, a package is used in which the opening side of the packaging bag is bundled and bound by various binding tools so that the opening of the packaging bag can be repeatedly opened and closed. However, simply bundling the opening side with a bundling tool does not completely block the bundling portion between the inside and outside of the packaging bag, resulting in a gap, leading to production and sales. There is a risk that foreign matter may enter the bag during the product distribution process. Then, as a packaging structure for preventing this foreign substance intrusion, the thing of patent 3032163 gazette is proposed, for example. In the packaging structure according to this proposal, a belt-like seal portion that substantially blocks the inside and the outside of the packaging bag is partially welded to the opening side of the packaging bag by a plurality of dot-like heat welding portions, By attaching and binding a binding tool corresponding to the seal position, the above problem can be solved.
[0003]
[Problems to be solved by the invention]
However, according to the above-described conventional technique, since it is necessary to match the sealing position with the binding position by the binding tool, it is not easy to perform reliable positioning when performing automatic packaging. Further, the belt-like seal portion is set to be easily opened by forming a plurality of dot-like heat weld portions. For this reason, depending on the form of the binding tool, when the binding tool is mounted at the sealing position, a strong force is applied to the belt-shaped seal portion, making it difficult to mount the binding tool, and in the worst case, the binding tool may be peeled off. Further, in the conventional technology, the belt-like seal portion is only partially welded by the dot-like heat weld portion, and is not sealed, so that it is insufficient to prevent foreign matter from entering the bag. Furthermore, in this prior art packaging structure, the belt-like seal portion is applied to the entire width while maintaining the form of the packaging bag (flat bag shape), so that the opening side is attached by attaching a binding tool to the seal portion. When bundled, the width of the bag ear portion that extends substantially fan-shaped from the bundling position to the opening side widens with respect to the width of the bag body portion, and there is a problem that the appearance is impaired.
[0004]
OBJECT OF THE INVENTION
In view of the above-mentioned problems inherent in the above-described conventional technology, the present invention has been proposed to suitably solve this problem, and can reliably prevent the entry of foreign matter into the bag and can be used for binding.

The gusset folds 20 and 20 on the opening side are formed (see FIG. 4), and at least the air in the bag extension is evacuated by a deaeration means or the like that is pressed from the outside. Under a substantially deaerated state, a plurality of belt-like seal portions 22 that are parallel to the opening end edge and are easy to open are positioned near the opening end edge of the bag extending portion 18 and close to the edge by heat sealing. Form and seal. The belt-like seal portion 22 includes, for example, a first seal bar having a grid-like concave seal surface and a second seal bar having a seal surface in which a plurality of convex protrusion seal portions are arranged at predetermined intervals in the vertical or horizontal direction. It is formed by bringing them into contact with each other. That is, in this case, the bag extending portion 18 is pressurized and heat-sealed at the contact portions of both the concave and convex seal surfaces, and the portions where the concave and convex seal surfaces do not contact on both sides of the corresponding contact portions (the portions that are not pressurized) Then, a heat seal weaker than the pressure heat seal at the contact portion is applied, and easy opening with fingers is possible. Even if a second sealing body having a flat sealing surface is used, the band-shaped sealing portion 22 that can be easily opened can be formed. Incidentally, the heat sealing means is composed of the first seal body and the second seal body, but this means may be a seal roller or the like.
[0018]
Next, the bag extension is carried out in a state where the bag extension 18 is sandwiched by appropriate holding means with respect to an appropriate position between the article storage edge 17 and the belt-like seal portion 22 in the bag extension 18. One end portion in the extending direction of the band-shaped seal portion 22 in the portion 18 and the slit 26b side of the binding tool 26 are opposed to each other and close to each other, and the bag extending portion 18 is connected to the hole portion through the slit 26b. The binding tool 26 is attached to the bag extending portion 18 by being inserted into the bundle 26a and being bundled. Thus, the opening side of the packaging bag 12 is bound by the binding tool 26.
[0019]
In the bag-bound product bundling method according to the embodiment, the bundling tool 26 is attached and bundled at an appropriate position in the packaging bag 12 from the article storage edge 17 to the belt-shaped seal portion 22, so that the sticking position is particular. In addition, the binding tool 26 can be positioned close to the edge of the bread 14, and the package 10 that suppresses the looseness between the packaging bag 12 and the bread 14 can be manufactured. Further, since it is not necessary to match the sealing position and the binding position, automatic packaging is facilitated. In addition, since the binding tool 26 is attached to the bag extending portion 18 at a position that does not interfere with the belt-like seal portion 22, the attachment is easy, and a strong force is applied to the belt-like seal portion 22 when the binding tool 26 is attached. Peeling is suppressed.
[0020]
In the above-described embodiment, the binding tool is attached to the bag extending portion between the belt-like seal portion formed on the bag extending portion and the article accommodating edge, but the position where the belt-like seal portion is close to the article accommodating edge. In addition, the binding tool may be mounted at an appropriate position from the belt-shaped seal portion to the opening edge portion. Further, the number of the band-shaped seal portions formed is not limited to two as in the embodiment, and may be only one or three or more. Further, the seal width can be freely set as required.
[0021]
As a means for easily sealing the belt-like seal portion, the film material is subjected to special processing or processing, or the seal temperature is set to a low temperature or the seal pressure is set to a low pressure, and the film is heat-sealed by a combination thereof and sealed. Various means can be adopted as appropriate, but even in such a case, the packaging material can be opened with the function of the packaging bag maintained without tearing or tearing the film of the bag material. That's fine. As for the seal of the belt-like seal portion, any one or a combination of a solid shape and other various welding states can be employed. In addition, as breads accommodated in a packaging bag, it is not limited to bread made of a plurality of slice breads, but may be unsliced bread or other forms of bread such as roll bread and French bread.
