Description

[Detailed explanation of the idea] Industrial applications This proposal relates to improvement of an oxygen absorber storage bag.

PRIOR ART Oxygen absorbers are devices that are placed in a sealed container together with foods, etc. to absorb oxygen in the container and thereby improve the shelf life of the contents. The drug is a film-like packaging material made of a combination of paper or non-woven fabric and perforated PE (polyethylene film),
It was housed in a bag made of a film-like packaging material made of a combination of perforated PE (polypropylene), paper or nonwoven fabric, and perforated PE.

Problems that the invention aims to solve Since the above-mentioned bags are breathable, they are effective in increasing the oxygen absorbing effect, that is, the oxygen absorption effect. However, they have the disadvantage that they absorb oxygen from the atmosphere and lose their oxygen absorption performance by the time they are used.

Means for Solving the Problems Therefore, the technical problem of the present invention is to obtain an oxygen absorber storage bag whose oxygen absorbing performance does not disappear until the time of use, and the present technology to solve this technical problem is The objective means is to form a bag that can be sealed all around with a base material that does not permeate gas, and to partition the bag into an oxygen scavenger storage chamber and a vacant chamber that will serve as an air circulation chamber using a filter material that has air permeability. Hole points are provided in empty spaces in the filter medium that do not correspond to the oxygen scavenger storage chambers.

Effects of the invention In the product of this invention, the oxygen absorber is sealed by the base material during packaging, but during use, the oxygen absorber can be removed by making a hole in the hole for the punching point that does not contain the oxygen absorber. Since it is designed to be effective as an oxygen agent, the oxygen absorption performance will not be lost until the time of use.

In addition, since a hole is not directly drilled into the chamber housing the oxygen absorber, there is no possibility that the oxygen absorber will leak directly from the hole.

Example The embodiments shown in the drawings will be described below.

1 is a film-like base material that does not permeate gas, and specifically, for example, a so-called laminated film in which plastic film is attached to both sides of paper is used, and it has a certain degree of gas barrier property and is suitable for packaging machines. Good quality products are used.

Therefore, polyvinyl chloride resin coated biaxially oriented polypropylene and polyethylene, or polyvinyl chloride resin coated biaxially oriented polyester and pophenalene, etc. may be used as required.

Now, in order to form an oxygen absorber storage bag using the base material as described above, as shown in Figure 1.2, the entire circumference of the base material 1 is heated from above and below with the filter medium 2 in between. Seal it with a sealing device to create a bag with two upper and lower parts.

3 indicates the heat-sealed portion, and 4 indicates the partitioned space.

The upper base material 1 and the intermediate filter medium 2 are also thermally bonded 5 to each other and partitioned into chambers 6 and 7, one of which contains tablets or powder 8 of an oxygen absorber.

When the oxygen absorber is packaged as described above, the oxygen absorber is completely sealed and does not absorb oxygen from the atmosphere, so the oxygen absorbing performance is not lost. When a hole is made with a needle as shown in Figure 3, oxygen will be absorbed through the hole 9 through the path of filter medium 2 → chamber 4 → filtration medium 2 → oxygen scavenger 8, thereby reducing the original oxygen absorption effect. Since the bag can be enclosed in a container together with the intended food, etc., the preservability of the food can be improved.

Note that the intermediate filter medium 2 used in this case is required to pass air (oxygen) without passing through the fine powder of the oxygen scavenger, but the material may be the filter medium 2 or a material other than the filter medium 2, such as a net. good.

Further, the vacant room 6 serves as a punching point, but in actual sales, it is displayed to the user that it is a punching point.

If you make a hole in the empty chamber 4, you may accidentally insert the oxygen absorber into it, which may cause the filter medium 2 to tear more than necessary, and the oxygen absorber may leak out from the hole. Store the oxygen absorber according to the instructions.

Further, even if the filter medium corresponding to the chamber 7 is torn and the oxygen absorber leaks into the empty chamber 4, it will not leak from the hole 9.

In the case shown in Fig. 4, an oxygen scavenger storage chamber 7 is formed by adhering the filter medium 2 and the base material 1, but the inside of the bag is not completely partitioned, and the empty chamber 6 and the empty chamber 4 are connected. It has become.

In any case, the formation of the air 4 is necessary to improve air circulation, and the perforation point is provided in a space that does not correspond to the oxygen absorber storage chamber for the filter medium, and the oxygen absorber is powder, Any tablet may be used.

Although the illustrated packaging form is rectangular, any external shape can be adopted and the packaging form can be hung.
