Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a package in which a packaged product such as a food product is sealed in a cylindrical box container.

(Background of the invention) To explain the case where the packaged product is food as an example, it is generally important to prevent changes in the composition of food (preventing deterioration) during the distribution process, and in recent years such There have been remarkable advances in preservation technology for foods that have been provided for various purposes.

External factors that affect the preserved foods mentioned above include light, oxygen, temperature, humidity, microorganisms, enzymes, etc. However, the oxygen causes a decrease in nutritional value and a loss of flavor and color due to oxidation of the food. In addition to oxidation of oils and fats, the risk of food poisoning is an issue to be considered.

For this reason, conventional methods have been used to remove oxygen from food packages.
In addition to methods such as vacuum packaging or enclosing inert gas (usually nitrogen gas), recently, quality preservation agents (usually gas-permeable bags filled with oxygen-reducing packaging) are used. Therefore, hereinafter, it may be referred to as a deoxidizing package including the quality preservation agent)
It has also been practiced to include both in the package.

However, among the above-mentioned techniques for removing oxygen, when sealing a deoxidizing package together with food, the quality preservation agent in the deoxidizing package depends on the type of food to be sealed. It is necessary to give sufficient consideration to preventing the contamination of substances into food. This is because the oxygen absorbing packaging is used by filling a gas-permeable paper bag with an oxygen absorbing agent, so when the oxygen absorbing packaging is packaged with food and distributed, There is a risk that the body may rupture and the oxygen absorber may be mixed into the food.

Such a problem becomes particularly noticeable when the packaged food is a solid granule or the like.

(Purpose of the invention) The present invention has been made from the above-mentioned viewpoint, and its purpose is to create a suitable atmosphere in the package (for example, to remove oxygen) when the package is sealed together with a packaged product such as food. gaseous oxygen is removed by
To provide a package in which a quality-preserving agent is isolated so as not to mix into the packaged product, and the workability of incorporating the quality-preserving agent into the package is also good.

(Summary of the invention) Therefore, the characteristics of the package in which the quality preserving agent is sealed together with the quality preservation agent of the present invention, which was made to realize the above purpose, are that the package includes a bottom cover and a lid so as to seal the contents from the outside. A cylindrical packaging container body with a closed canopy: Fitted with the funnel-shaped peripheral edge touching the bottom lid or canopy of the container body and with the funnel-shaped tip facing inward of the container body. A diaphragm plate arranged to divide the inside of the container body into a space inside and outside the funnel: a food product filled in the outer space of the diaphragm plate; a quality preservation agent package inserted into the inner space of the diaphragm plate; The diaphragm plate is configured to allow gas flow between spaces on both sides isolated from the inside and outside.

In the above configuration, the container body may be made of metal plates such as tinned iron plates or aluminum plates, as well as cardboard, plastic, or a so-called laminate, which is a combination of these. For example, a well-known food packaging box in which a bottom lid and a top lid are integrated by caulking or the like can be used as is, and a so-called pull-top packaging box with an open top lid is particularly preferably used.

The packaged products filled in this container body are, for example, foods such as grains (rice, wheat, corn, barley, etc.), processed grains (alpha-ized grains, flakes, powder), Examples include, but are not limited to, milk powder, nuts, cutlets, potato chips, dried bonito flakes, dried vegetables, fruits, meat, and spices.

Packaged products other than foods may include vitamins or other pharmaceutical products in granular or powder form, or mechanical parts such as precision machine parts that require a high degree of rust prevention.

Due to the gas permeability of the package, the quality preservation agent, which is inserted and separated from the packaged food such as food inside the container body by the diaphragm plate, diffuses from the outside into the bag. For example, an oxygen scavenger filled inside fixes the gas entering the interior through an oxidation reaction. Alternatively, the active ingredients emitted by the quality preservation agent inside the package (e.g. CO ₂ , C ₂ H ₅ OH,
Commercially available products in which BHT (BHT) diffuses to the outside and acts on the packaged product can be used as is.

Examples of the quality maintaining agent include, in addition to the oxygen scavenger, a desiccant such as silica gel, a deodorizing agent such as activated carbon, and the like.

The diaphragm plate in the above configuration is in contact with either the bottom cover or the canopy of the container body and partitions and separates the package filling space and the quality preservation agent package insertion space in the container body, In order to prevent the insertion space for the quality preservation agent package from being crushed and to ensure isolation from the filled packaged product, the above-mentioned diaphragm plate formed in a funnel shape is preferably used. . This is because the funnel-shaped shape is effective in crushing strength against crushing force from the axial direction.

In particular, the diaphragm plate is preferably formed into a funnel shape by making a radial cut in a part of a stiff circular sheet made of plastic or cardboard, and overlapping both sides of the cut. used. This is because when such a circular sheet is formed into a funnel shape, the restoring force generated in the funnel-shaped diaphragm plate brings the periphery of the funnel-shaped diaphragm plate into close contact with the inner wall of the container body. This is because it will be done. In particular, in the above-mentioned normal food packaging boxes, when the bottom cover or top cover is integrated, a circumferential groove is usually formed in the cylindrical inner wall that contacts the bottom cover (or top cover). Because of this, the peripheral edge of the diaphragm plate fits into this circumferential groove, making it easy to ensure compartment isolation.
Moreover, there is an advantage that the workability of assembling the diaphragm plate becomes easier. This diaphragm plate is
It is formed by drilling or the like to allow gas flow between the inner and outer sides.

(Example of the invention) The present invention will be described below using as an example a case where Alpha rice shown in the drawings is used as a packaged product.

In FIGS. 1 and 2, 1 is a container body, which is composed of a body 2, a bottom lid 3, and a canopy 4, into which a diaphragm plate 10 and an oxygen removing envelope 19, which will be described later, are inserted. Other than that, it has the same structure as a known food packaging container in which a pull-top tab 9 is assembled to a conventional canopy 4. 2
0 indicates Alpha rice filled in the main container 1 as the food product of this example.

FIG. 3 is for explaining the details of the diaphragm plate 10 in the container body 1 shown in FIG. 1 and the procedure for assembling it.

In the above, the diaphragm plate 10 is made of a circular sheet (flat plate-like in its natural state) made of a relatively stiff material such as plastic and has perforated air circulation holes (ventilation holes) 12. One cut line 13 is made as a radius line from the center of the circle to the outer circumference, and both sides of this cut line 13 are overlapped as shown in Fig. 3C to form the diaphragm plate into a funnel shape. is 15).
By assembling this funnel-shaped diaphragm plate 10 inside the canopy 4 of the container body as shown in FIG. 3F, installation of the diaphragm plate 10 into the container body is completed. At this time, in the above-mentioned known food packaging container, when the canopy 4 is integrated with the body of the container body, a guard bead 7 is formed in the vicinity of the upper winding part 6 and protrudes circumferentially toward the inside of the container. As a result, a circumferential recess 8 is formed between the guard bead 7 and the canopy 4, so the outer peripheral edge of the funnel-shaped diaphragm plate 10 is fitted into the circumferential recess 8. Then, due to the restoring force of the funnel-shaped diaphragm plate 10 to the flat plate state, an assembled state in which dislodgement is reliably prevented can be obtained.

FIG. 4 is a diagram illustrating an example of the production procedure for producing a food package using the container configured as described above, except for the insertion and assembly of the deoxidizing package 19 and the diaphragm plate 10. The procedure is the same as the creation procedure. That is, the deoxidizing package 19 is dropped into the body part 2 in an inverted state with the canopy 4 integrated in advance, and then the diaphragm plate 10 is inserted and assembled as explained in FIG. 3 above. The above-mentioned preparation is completed by the well-known procedure of filling the bottom cover 3, assembling the bottom cover 3, inverting it, and assembling the polyethylene cover 21, for example.

According to the above, in the obtained food package, the deoxidizing package 19, which is separated from the filled foods 20 by the diaphragm plate 10, is enclosed together with the package, and the diaphragm plate According to No. 10, the deoxidizing packaging 19 does not come into contact with the filled foods 20, so there is no risk of the deoxidizing packaging being damaged, and therefore, the quality preservation agent is mixed into the foods. You can get the effect that there is no problem. Further, the work of assembling the deoxidizing envelope 19 and the diaphragm plate 10 is easy, and the diaphragm plate 10 does not come off after being assembled, so the practical effect is extremely large.

Furthermore, in the above example, the space separated from the food items by the diaphragm plate can also be used as an insertion space for small bags filled with cooked ingredients or seasoning liquid.

FIGS. 5 to 12 each show other examples of the diaphragm plate used in the present invention,
In these examples as well, effects similar to those of the above examples can be obtained.

Further, in the example shown in FIGS. 13 and 14, a large number of short radial peripheral notches 16 are cut into the outer peripheral edge of the diaphragm plate at intervals in the circumferential direction to form a funnel-shaped diaphragm plate. A case in which a peripheral edge rising tongue piece 17 is provided is shown.

(Effects of the invention) As described above, according to the packaging for foods, etc. of the invention, the quality preservation agent sealed in the packaging together with the packaged food, etc. The surrounding atmosphere is suitably realized by, for example, removing gaseous oxygen, and the quality preserving agent is reliably isolated so that it does not get mixed into the packaged products such as the above-mentioned foods, and furthermore, it Since it is possible to provide a package with good workability in incorporating the diaphragm plate or the quality preservation agent, the practical effects thereof are extremely large.
