Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a quality-preserving material for purposes such as sterilization, insecticidal, deodorizing, and decolorizing.

(Prior Art) As is well known, ozone is used for various sterilizing purposes, insecticidal purposes, deodorizing purposes, decolorizing purposes, and various chemical reactions due to its strong oxidizing power.
It can be generated by photochemistry, radiation, electrolysis, electrical discharge, etc., but industrial production has ranged from photochemical methods using ultraviolet lamps to silent discharge using glass tubes, and now also using surface discharge methods using new ceramics. ing.

If you want to use this ozone to sterilize fruits and vegetables, eggs, seafood, fish tanks, human waste, etc., kill insects, deodorize, and decolorize, bring an ozone generator to a factory or warehouse with a secure power source. There is a need.

(Problem to be solved by the invention) However, when using ozone for the above purpose, it is essential to secure a power source and bring in an ozone generator, which inevitably requires a large scale. Therefore, its scope of use has been severely limited. For example, it is virtually impossible to attach an ozone generator to puff cages (each packaging unit) of fruits and vegetables, eggs, and seafood sold at retail in supermarkets and the like.

Further, as a sterilizing, insecticidal, and decolorizing means other than ozone, a chlorine generating agent containing chlorine dioxide is commercially available, but it is not preferable especially for food applications because of hygienic problems.

(Means for Solving the Problems) The present invention was invented in view of the above-mentioned problems, and does not require an ozone generator or a power source.
The aim is to provide a portable quality-preserving material that can stably generate the required amount of ozone.

The configuration of the present invention will be explained below.

That is, the gist of the present invention resides in a quality maintenance material characterized in that an ozone adsorption carrier is enclosed in a packaging material.

In the present invention, ozone may be generated by a conventional ozone generator, and the ozone adsorption carrier means a carrier that adsorbs and retains ozone inside, and here,
As a carrier for adsorbing ozone, for example, ordinary adsorbents such as silica gel, activated carbon, diatomaceous earth, and silicone, polyethylene glycol, etc. can be used, and inorganic substances with adsorption performance such as alumina and activated clay can also be used. Can be used. Furthermore, the carrier may be coated with a liquid alkali such as caustic soda or potassium peroxide sulfate, or a polymeric resin having adsorption ability.

Furthermore, a porous carrier in which a liquid alkali alone is adsorbed can also be used as the carrier.

In short, any material may be used as long as it has a porous structure and is sufficient to adsorb ozone, but it should be selected appropriately in consideration of the amount of ozone adsorbed, its adsorption and retention capacity, etc.

It goes without saying that the ozone adsorption carrier according to the present invention also has an ozone release ability capable of continuously releasing ozone from within the carrier under conditions of normal temperature and normal pressure.

In addition, the size and packaging form of the quality-preserving material of the present invention can be freely selected and designed, such as packing it into a bag-like or cylindrical packaging material, or laminated sheet-like structures sandwiched between intermediate layers, etc. Choose the packaging format that is easiest to use depending on the purpose.

Furthermore, packaging materials for enclosing (packaging, sealing, or clamping) the carrier include ozone-permeable packaging materials and high-barrier or gas-barrier packaging materials (hereinafter simply referred to as barrier packaging materials) that have the opposite properties. The former may include, for example, ordinary synthetic resin films such as polyethylene and polyvinyl chloride, as well as paper, which has the property of being permeable to ozone. It's enough if you have it. On the other hand, as the barrier packaging material, for example, a composite film such as an aluminum vapor-deposited film is desirable. Among these packaging materials, the most appropriate one is selected depending on the amount of ozone volatilized and released and the packaging form of the ozone adsorption carrier.

(Example) Next, typical examples of the quality maintenance material of the present invention will be described based on the accompanying drawings.

Example 1 FIG. 1 is a perspective view showing the cross-sectional structure of a quality maintenance material in which an ozone adsorption carrier is enclosed in a bag.

In the drawing, reference numeral 4 denotes a quality maintenance material, which is constructed by enclosing an ozone adsorption carrier 1 in a bag body 2.

As mentioned above, the bag is usually composed of an ozone-permeable packaging material (for example, an ozone-permeable film such as polyethylene film), but in this case, the ozone evaporates by the time of use and the efficacy is lost or reduced. Usually, so as not to
Store in a barrier film bag, etc.

In addition, instead of ozone-permeable packaging material, the bag body may be made of a packaging material with excellent barrier properties (for example, aluminum vacuum-deposited film, etc.). There is no problem in drilling the holes. Alternatively, the slits or pores may be made in advance and closed with a stickable seal, and the opening may be provided by removing the seal at the time of use.

Example 2 FIG. 2 is another example, and shows a perspective view of a sheet-like quality maintenance material in which an ozone adsorption carrier is sandwiched between two ozone-permeable packaging materials and laminated together.

In this drawing, the reference numeral 4' denotes a sheet-like quality maintenance material, which is constructed by integrally laminating an ozone adsorption carrier 1 between two ozone permeable packaging materials 3.

Note that, as a means for sandwiching and laminating and integrating the carriers, various laminating methods may be used, for example.

(Application example) An actual application example of the quality maintaining material of the present invention will be explained.

Application Example 1 FIG. 3 is an explanatory diagram when the quality maintaining material of the present invention (shown in FIG. 1) is applied to maintaining the freshness of fruits and vegetables.

In the figure, reference numeral 4 is a quality maintenance material, and fruit and vegetable 5
In addition, an appropriate number of containers are packed in a packaging box 6 such as a cardboard box. If the quality preservation material is increased in proportion to the number of fruits and vegetables, more effective freshness of fruits and vegetables can be expected.

Application Example 2 FIG. 4 is a sectional view showing a case where the quality maintaining material of the present invention is added to a package of seafood.

In the figure, reference numeral 4 denotes a quality maintenance material, which is attached to the back surface of the lid 7 by appropriate means.

Note that 8 is a storage container such as a plastic tray, and 9 is fresh fish.

Application example 3゜Figure 5 is a cross-sectional view of a case where the lid of a box-shaped container for eggs, etc. itself is a sheet-like quality maintenance material (as shown in Figure 2) in which an ozone adsorption carrier is sandwiched between intermediate layers. be.

In the figure, the reference numeral 4° indicates a sheet-like quality maintaining material that also functions as a lid. Note that 10 is a packaging container such as a plastic case, and 11 is an egg.

(Function) Therefore, when the quality preservation material of the present invention is attached or enclosed in a container when packaging fruits and vegetables, fresh fish, eggs, etc., ozone is gradually removed from the ozone adsorption carrier in the quality preservation material in the container. It evaporates and is released, filling the container. The strong oxidizing power of this filled ozone is responsible for the sterilization or insecticidal action of germs, bacteria, insect pests, and their eggs that exist in the container or adhere to the stored items, and also oxidizes and decomposes odor components that remain inside the container. It is responsible for the deodorizing effect. Although the above example is an example of application to food, it goes without saying that when the quality preservation material of the present invention is applied to applications for the purpose of decolorization and deodorization, effective action can be expected due to the strong oxidizing action of ozone. do not have.

(Effects of the Invention) The quality maintaining material of the present invention configured as described above has the following effects.

1) First, the quality-preserving material of the present invention can be packaged in a laminated sheet form or in a bag, and the form can be freely selected depending on the application, and the size can also be changed. It is very easy to use because you can choose.

2) Secondly, there is no risk of causing any pollution problems even if the used quality preservation material is disposed of, so it can be used with peace of mind.

3) Thirdly, when the ozone adsorption carrier is encapsulated in a barrier packaging material, the ozone adsorption carrier Karasushin is continuously released only when cuts or micropores are provided in the packaging material during use. Therefore, there is no risk of the ozone's effectiveness decreasing until it is about to be used.

4) Fourth, in cases where the ozone adsorption carrier is encapsulated in an ozone-permeable packaging material, by keeping it encapsulated in the barrier packaging material until just before use, it is possible to prevent a decrease in the effectiveness of ozone, and the barrier film is removed at the time of use. By taking it out of the bag and using it, you can expect the desired effect.

5) Fifth, when using the quality-maintaining material of the present invention, there is no need for an ozone generator or any power supply, and not only is the shape compact enough to be carried, but the ozone volatilization and release start time is the same as the start of use. Since it is possible to match them, it is possible to accurately design according to the application, and also,
It is so easy that anyone can use it regardless of time or place, and there are no restrictions on its use.

6) Sixth, according to the present invention, by utilizing the difference in ozone adsorption ability and ozone release ability of the carrier that adsorbs ozone,
By creating multiple quality maintenance materials using multiple types of ozone adsorption carriers and appropriately combining them, it is possible to adjust the ozone release amount, release time (efficacy period), and constant concentration persistence (efficacy stability period). Because of this, it is possible to provide detailed responses depending on the target to which it is applied.
