Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spacer interposed between packagings such as corrugated cardboard boxes containing articles, and particularly to a horticultural crop having a life reaction in a packaging such as a corrugated cardboard box. When packed and transported in a refrigerated container or stored, an air circulation path is secured between the packages to effectively dissipate and remove volatile gas generated and diffused from horticultural crops and improve the partial retention of moisture in the warehouse. The present invention relates to a spacer for a loaded horticultural crop package, which can prevent spoilage and maintain freshness by maintaining proper humidity.

[0002]

[Prior Art]

 The crops produced are combined with forcing, ordinary, and restrained cultivation in combination with breed improvement, improvement of cultivation techniques, and diffusion of production materials, etc., and cultivation is expanded. , The distribution of excellent products throughout the season has come to be seen.

On the other hand, the freshness-keeping transportation and storage technology of harvested products have also been remarkably advanced. Techniques advanced from the viewpoints of freshness preservation transportation and storage include, for example, the techniques disclosed in JP-A-2-71074 and JP-A-2-71077. This is a technology that controls temperature and humidity, adsorption of volatile gases, and internal cold temperature control by circulation of wind (light breeze), and is highly effective for long-term sea, land transportation and storage. I'm giving it up.

[0004]

[Problems to be solved by the device]

 However, even if such a freshness-keeping technology for horticultural crops is used, due to the overreliance of its advanced freshness-keeping technology, the temperature dependence that is the basis of fresh produce, the correlation between temperature and ethylene gas generation, atmospheric concentration, The current situation is to forget about allelopathy and circulation of the wind, induce deterioration of the product, and dispose of it due to more than expected decay.

In other words, the preserving environment of each cultivated or harvested horticultural crop is carried out by a method that matches its use and purpose, and the preservation of vegetables, fruits, etc., whose freshness is an important condition, is・ Humidity control, elimination of volatile gas (mainly ethylene gas), and in-chamber control technology under the environment where wind circulates, while long-term freshness transportation and storage have almost reached the goal in practical use. However, depending on the conditions of the harvest, for example, if the production area without pre-cooling / pre-measuring facilities or the boxed product of high-temperature horticultural crops with insufficient pre-measuring is transported or stored, the load may be excessive. If the cardboard boxes are stuck together and there are no gaps in the stack, the flow of air inside the cabinet is obstructed, and the preserving function does not operate normally and the quality deteriorates. In other words, horticultural crops grow from aging to rot based on the principle of "temperature dependence" in terms of plant physiology, but temperature and ethylene gas (effective as a growth hormone at the beginning of growth, when the plant exceeds the ripening period) (Related to aging and decay) is correlated with the amount of produced and diffused substances, and there is also a correlation between temperature and respiratory volume (measured by the amount of CO2 emitted), and at high temperatures, harmful volatile gas is induced by active respiratory action. Because of frequent occurrence, even if a freshness preservation device is installed during transportation or during storage, if the flow of wind is obstructed, high temperature accumulated from the center of the cargo, harmful gas, and stuffiness and bacteria due to excessive humidity are generated. It becomes a bad condition such as, etc., and in combination with allelopathic effect (allelopathic effect), deterioration and decay will rapidly occur.

In order to prevent this, it is necessary to carry out proper loading so that the air passage can always be secured, but in reality, in order to reduce transportation costs, there is a case of transportation or storage by overloading. The vicious cycle of quality deterioration has not been improved due to the close contact with no gaps. On the other hand, if a gap is created to secure an air passage during loading in order to effectively operate the fresh-keeping function, the cargo may collapse during transportation and the contents may be damaged. Although it is possible to secure an air passage by interposing a spacer during loading, a spacer suitable for use in such a refrigerating container has not been developed so far, and it has not been used. Moreover, generally, the conventional stacking spacers are merely interposed between the storage bodies as shown in, for example, Japanese Utility Model Laid-Open No. 3-15377 and Japanese Utility Model Laid-Open No. 62-99546. There was a problem that it was troublesome to handle and there was a gap when loading because it did not have a simple fixing means to the body.

In view of the above, the present invention can be easily and surely mounted on an appropriate place such as a side surface or an upper surface of the package when the container is loaded in the refrigerating container, and moreover, the air passage of the package can be surely secured. However, it is an object of the present invention to provide a spacer for a loading package that ensures the preservation of stored horticultural crops, prevents collapse of loads, and buffers loads.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the spacer of the present invention has a spacer body formed of an elastic material such as polystyrene foam, an adhesive surface formed on the surface thereof, and the adhesive surface covered with a release material. It is characterized by. Then, among the adjacent or overlapping cardboard boxes, the adhesive surface of the spacer from which the release material has been removed is adhered to the side surface or the top surface of the cardboard box on one side to attach the spacers, or It is designed to separate the overlapping parts from each other and to secure a circulating air path between them.

As a material of the spacer body, a material having elasticity such as styrofoam, foamed ABS, foamed vinyl chloride, and foamed polyurethane, which is lightweight, inexpensive and easy to process is preferable.

The shape of the spacer body is not particularly limited, but the spacer of the present invention is one having flat surfaces such as between cardboard boxes or between box-shaped packages and between box-shaped packages and container walls. Since the spacer is interposed between the two and the spacer is attached to the flat surface of the package to separate the two and form the air passage, it is a plate shape with at least one flat surface. , Rectangular parallelepiped shape, cubic shape, and semi-cylindrical shape are preferable.

The adhesive surface is formed by applying a conventionally known adhesive that can be firmly fixed to a cardboard box or the like, and is usually covered with a release material, and the release material at a necessary portion is peeled off at the time of use. The place where the adhesive surface is formed is not particularly limited. For example, in the case of a rectangular parallelepiped spacer body, if the adhesive surface is formed on three surfaces of different shapes, the adhesive surface can be formed according to the size and purpose of the cargo. Therefore, it is preferable that three different ways of using different air passage widths are possible.

The release material is obtained by coating the surface of a release sheet with a release agent. As the release sheet, a plastic film such as polyethylene or polypropylene or a metal film such as an aluminum foil is used, and as the release agent, a silicone-based release film is used. Materials are used. Then, it is necessary to cover the entire adhesive surface with this release material, but if at least one end of the release material has a play allowance that does not cover the adhesive surface, it is possible to easily remove the release material with that play allowance. It is preferable that the spacer can be easily attached during work.

[0013]

[Action]

 Since the spacer body is formed of an elastic material such as Styrofoam, the adhesive surface is formed on the surface, and the adhesive surface is covered with a release material, the release material is removed and the adhesive surface is covered with a corrugated cardboard box or the like. It can be easily attached to a package by pressing it against the package, and a gap can be formed between adjacent packages.

Since the material is lightweight and adheres to the packaging body at the adhesive surface, the spacers that have adhered do not fall off during the loading work, and the loading operation while separating the packaging bodies is efficient. I can do it well. In particular, when loading in a refrigerating container, a gap can be easily formed between the container and the wall. Also, since it is a spacer made of an elastic material, it exerts a buffering effect against shocks during sea transportation or land transportation, and is suitable for protecting vegetables and fruits in the contents of the package.

Further, if a rectangular parallelepiped spacer body is used and three differently shaped adhesive surfaces are formed, the adhesive surfaces can be selectively used according to the size and purpose of the cargo to be used in three different ways. You can

[0016] Further, if the play allowance not covering the adhesive surface is formed on at least one end of the release material, the release material can be easily peeled off with the play allowance, and the spacer can be easily attached during the loading operation.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing an example of a spacer according to the present invention. The spacer 1 is formed by forming adhesive surfaces 3a, 3b, 3c on three different surfaces 2a, 2b, 2c of a rectangular parallelepiped-shaped spacer body 2 and peeling them off. The materials 4a, 4b, 4c are peelably coated.

The spacer body 2 is made of a material such as styrofoam, which is elastic, inexpensive, and easy to process, such as foamed ABS, foamed vinyl chloride, and foamed polyurethane. In this embodiment, the length is 10 cm and the width is 10 cm. It has a size of 7 cm and a depth of 5 cm.

As shown in FIG. 2, the adhesive surfaces 3a, 3b, 3c are coated with a pressure sensitive adhesive 5 of natural rubber type, butyl rubber type, recycled rubber type, acrylic type, etc. Covered with c. The release materials 4a, 4b, 4c are release sheets coated with a release agent. As the release sheet, a plastic film such as polyethylene or polypropylene or a metal film such as aluminum foil is used. Silicone material is used for.

The release materials 4a, 4b, 4c cover the entire adhesive surfaces 3a, 3b, 3c, and one end of the release materials 4a, 4b, 4c does not cover the adhesive surfaces 3a, 3b, 3c. A is formed. At the time of use, the release material 4a, 4b, 4c can be easily peeled off with this play allowance A, and the spacer 1 can be easily attached during the loading operation.

In this embodiment, since the adhesive surfaces 3a, 3b and 3c are formed on the three surfaces of the rectangular parallelepiped spacer body 2 having different shapes as described above, the adhesive surfaces 3a, 3b and 3c are formed depending on the size and purpose of the load. It is possible to use 3b and 3c properly, and it is possible to use 3 ways with different air passage widths.

The spacer body of the present invention is not limited to a rectangular parallelepiped shape because it has a flat surface capable of forming an adhesive surface on at least one surface. For example, a plate shape, a cube shape, a semi-cylindrical shape may be used. Of course, other shapes such as a body shape may be used.

FIG. 3 shows an example of using the spacer 1 of this embodiment, showing an example of stacking cardboard box packages 11 containing horticultural crops such as vegetables and fruits in a refrigerating container 10. ing.

That is, when the corrugated cardboard box packages 11 for storing horticultural crops are stacked in the refrigerating container 10, the appropriate surface of the spacer 1 is adhered to the side wall, bottom wall or upper wall of the cardboard box package 11. The surfaces are adhered to each other and gaps having a spacer width are formed between the corrugated cardboard box packages 11 and between the corrugated cardboard box packages 11 and the refrigerating container 10 to form an air passage B for circulating air in the refrigerator.

As a result, even when the cardboard box packages 11 are fully loaded, the circulating air in the refrigerator is evenly circulated in the air passage B to prevent ethylene gas and moisture from staying and to preserve the stored horticultural crops. It is possible to prevent the collapse of the cargo and to buffer the cargoes with each other.

In the above-mentioned embodiment, the spacer 1 is stacked on the refrigerating container 10 to isolate the corrugated cardboard box package 11 for storing horticultural crops. However, the spacer of the present invention is used for separating vegetables and fruits. Not only when stacking corrugated cardboard boxes containing horticultural crops, but also various electronic products such as seeds, ceramics and glass products, personal computers, TVs, refrigerators, consumer products, wood products, plastic products, etc. It is also applicable to the case where the cardboard box is housed, the cardboard box is housed in the container, or the carton box is directly transported by a ship, a cargo, a truck, or an aircraft. By using the spacer of the present invention, it is possible to easily interpose spacers between stacked corrugated cardboard boxes simply by peeling off the release material, which makes the loading work easier and easier than conventional spacers, and also buffers the loads. In addition, since the spacer is fixed, it is possible to prevent the spacer from falling off and slipping, which is also effective in preventing load collapse. Further, the spacer of the present invention can be sufficiently applied to a case where a container for articles such as a plastic box or a wooden box other than a cardboard box is used.

Next, an experimental example of forming the air passage B by using the spacer 1 shown in the above-mentioned embodiment of the present invention when the horticultural crops (melon) are stored in a cardboard box and stacked in a refrigerating container The difference will be described with reference to FIG. 1 in FIG. 4 and Comparative Example 1 in which the air passage is blocked without using a spacer.

(Experimental Example 1) FIG. 4 shows a melon-containing cardboard box fully stacked in a refrigerating container in which a temperature / humidity control, a volatile gas adsorption and an air circulation device are operated, and FIG. As described above, the freshness of the melon is measured when the spacer 1 is interposed.

The experiment was conducted at an outside air temperature of 29 ° C., an inside temperature of 2 ° C., and a humidity of 90% RH by setting adsorption of volatile gas (mainly ethylene gas) and circulation of air.

The melons at the time of storage are suitably ripe fruits with a skin temperature of 18 ° C. and a core temperature of 16 ° C. Each of the six melons is housed in a corrugated cardboard box having ventilation holes on its side.

The measurement position is the central portion of the fully loaded state, and the figure shows the results of changes over time.

As is clear from the graph of FIG. 4, the air flow was smoothly circulated by securing the air passage by the spacer, and both the skin temperature and core temperature of the melon dropped normally. That is, the skin temperature of melon was 6 ° C on the 2nd day, 3 ° C on the 3rd day, 2 ° C on the 4th day and thereafter, and the core temperature was 9 ° C on the 2nd day, 5 ° C on the 3rd day, and 5 days. 3 ° C was recorded in the eye, and approximately 2 ° C was recorded after the 7th day.

Further, the diffusion amount of ethylene gas involved in growth and aging was gradually suppressed as the product temperature decreased, with the skin temperature of 3 ° C. on the 3rd day as a branch point. Then, the ethylene gas value (B value) reached 50 on arrival, 100 on the second day, 110 on the third day, but decreased thereafter, and the peak could be suppressed to a low level of 110. Therefore, almost all of the freshness could be maintained with a very slight progress of maturity.

It should be noted that the ethylene gas value (B value) causes a difference in electric resistance value depending on the concentration when ethylene gas is burned, but here, the resistance value is converted into a digital numerical value to obtain a standard deviation. It was measured by the value method.

Comparative Example 1 FIG. 5 shows a comparative example in which the melon-containing corrugated cardboard boxes are fully stacked in a state in which the air passage is not secured by the spacers. All are the same as Experimental Example 1 except that the spacers are not used. It is measured under the conditions.

As is clear from the graph of FIG. 5, the results showed that the circulation of air was hindered, so that neither the skin temperature nor core temperature of melon fell normally. That is, the skin temperature of the melon was 17 ° C on the 3rd day, 14 ° C on the 4th day, 9 ° C on the 5th day, 4 ° C on the 6th day, and 2 ° C after the 9th day. The temperature was recorded as 16 ° C on the 2nd day, 15 ° C on the 4th day, 6 ° C on the 7th day, and 3 ° C on the 12th day.

Regarding the diffusion amount of ethylene gas involved in growth and aging, the generation amount was slowly suppressed according to the decrease in the product temperature, with the skin temperature of 4 ° C. on the 6th day as a branch point. As a result, the high-concentration gas in the atmosphere stayed for a long time and the quality was overripe, and the solid at the center of the cargo was allelopathic (allelopathic) due to the generation of acetaldehyde, ethyl acetate and some alcohol. And caused the overall quality to deteriorate.

Then, the ethylene gas value (B value) of the suitably mature melon solid reached a peak at a high level of 50 at the time of storage, 150 on the 4th day, 170 on the 6th day, and then decreased in accordance with the temperature decrease. ..

When the B value of 50 is appropriately matured by the standard deviation method, when it rises up to around 150, it becomes overripe, the meat sags around 250, and rots around 350.

In this comparative example, when the ethylene gas value reached 150 on the 4th day and 170 on the 6th day, the product became overripe and partly fermented fruits were produced, which was not sufficient to maintain freshness. It was. This is because the air passage was blocked and the temperature, humidity and ethylene gas control functions did not operate normally.

As is clear from the results of Experimental Example 1 and Comparative Example 1 as described above, when the spacer of the present invention is used, the air passage is ensured even in the fully loaded state in the refrigerating container, and the horticultural crops are secured. It was effective in keeping the freshness of. In addition, since the spacer can be attached to the cardboard box during loading, it was easy to handle and did not fall off or shift, making work more efficient.

[0042]

[Effect of the device]

 As described above, the spacer of the loading package of the present invention forms the spacer body with an elastic material such as Styrofoam, forms an adhesive surface on the surface, and covers the adhesive surface with a release material. Therefore, it can be easily attached to the package by simply peeling off the release material and pressing the adhesive surface against the package, such as a cardboard box, and forming a gap that becomes an air passage between adjacent packages. be able to.

Since the material is lightweight and adheres to the package at the adhesive surface, the adhered spacer does not fall off during the loading operation, and the loading operation while separating the packages is efficient. I can do it well. In particular, when loading in a refrigerating container, a gap can be easily formed between the container and the wall. In addition, since it is a spacer made of an elastic material, it acts as a buffer against shocks during sea and land transportation, and can protect vegetables and fruits in the package contents.

If a rectangular parallelepiped-shaped spacer body is used and three differently shaped adhesive surfaces are formed, the adhesive surfaces can be selectively used according to the size and purpose of the load, and three different gaps can be used. it can.

Furthermore, if a play allowance not covering the adhesive surface is formed on at least one end of the release material, the release material can be easily peeled off with the play allowance, and the spacer can be easily attached during the loading operation.
