Abstract

PURPOSE:To always fulfill well a valve function for gas ventilation, by comprising a plurarity of liner slits at the gas ventilation part for the gas generated from contents in a packing bag equipped with gas vent valves. CONSTITUTION:At required spots on the surface of a packing bag 1, a plurality of slits 4 are cut for gas vents 3 in parallel with each other, and at specified distances. Valves 5 for the gas vents equipped to cover the gas vents 5 (slits 4) on the sealed packing bag 1 comprise a base film plate 6, a cover film 7 and a valve body 8. The valve bag 8 closes ordinarily a circular hole 9 to completely seal the sealed packing bag 1. But when the inner pressure of the bag 1 rises due to generation of the gas by the granular contents filled in the bag 1, the high pressure gas presses the folded part 16 of the valve body 8, passing through the slits 4 constituting of the gas vents 3 of the bag 1 and also the circular holes 1 of the base film plate 6, forming a space between the valve body 8 and the base film plate 6 and then the gas flows out from the both open side edges 14, 14, which are not sealed, of the cover film 7.

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method for filling a container with contents that generate a small amount of gas during storage, such as roasted coffee beans, and removing the gas generated from the contents. This invention relates to a packaging body that allows gas to escape to the outside.

Conventionally, when roasted coffee beans, etc. are filled in a sealed package, gas is generated from the contents, causing problems such as expansion and tearing of the sealed package. A gas venting device that forms a gas venting portion through which the generated gas can pass, covers the gas venting portion to normally close the gas venting portion, and opens the gas venting portion when the internal pressure of the sealed package increases. Various types of gas venting valves have been proposed (Japanese Patent Laid-Open Nos. 56-32244 and 57-1538).
No. 58, No. 60-57069, No. 63-6278,

In this case, the shape of the degassing part of the package is often a circular hole, but in Japanese Patent Publication No. 60-55376, a semi-circular hole is used to prevent the outflow of particles such as ground coffee contained in the package. [Problems to be Solved by the Invention] However, when the semicircular arc-shaped cut tongues proposed in the eight proposals in Japanese Patent Publication No. 60-55376 are formed on a package, When the internal pressure of the package increases and the internal gas escapes from the gas venting valve to the outside through this cut, the internal gas presses the tongue and pushes the tongue toward the gas venting valve. A problem arises in that granular contents such as coffee beans get caught between the tongue and the cut edge of the package, or leak into the degassing valve, impairing the valve function of the degassing valve.

The present invention has been made in view of the above circumstances, and even when granular contents such as coffee beans are filled, the contents do not leak from the gas venting part to the gas venting valve side. It is an object of the present invention to provide a gas-ventable package that can always perform the valve function well.

In order to achieve the above-mentioned object, the present invention is filled with contents that generate a small amount of gas during storage, and is provided in a sealed package that is formed with a degassing section through which the gas generated from the contents can pass. A gas venting package is provided with a gas venting valve that covers a gas venting portion to normally close the gas venting portion and opens the gas venting portion when the internal pressure of the sealed package increases. The gas venting section is composed of a plurality of linear slits.

In the degassing package of the present invention, when gas is generated from the contents filled inside and the internal pressure rises, the gas escapes to the outside through the degassing part and the degassing valve. However, in this case, the gas venting section is formed of multiple linear slits, so the gas flows through these slits to the gas venting valve, but the granular contents such as coffee beans are separated from the slit spacing. Since the particle size is large, it cannot pass through this slit, and therefore, the contents are reliably prevented from entering the gas venting valve. Therefore, the valve function of the degassing valve is always performed satisfactorily. Also, in this case, if the packaging material is in the form of a film, it is made up of multiple slits, so the internal pressure slightly lifts the band-shaped part of the film between the slits, allowing the gas to flow out smoothly. It is something.

Further, the valve body 8 is made of the base film 6 and the cover film 7.
It is inserted between the base film 6 and the cover film 7, and has a configuration in which a rectangular plastic film is folded back with its center line shifted, and its extending end 15 is attached to one side of the base film 6 and the cover film 7. The valve body 8 is bonded to the portion 13 while being sandwiched between the two films 6 and 7, and the folded portion 16 of the valve body 8 is arranged to cover the circular hole 9 of the base film 6. In this case, the valve body 8 is biased so that the folded portion 16 presses the base film 6.

As a result, the folded portion 16 comes into close contact with the surface of the base film 6 and closes the circular hole 6, and when high-pressure gas presses the folded portion 16 from the side of the circular hole 9 against the urging force of the folded portion 16, The folded part 16 is lifted to form a gap between the valve body 8 and the base film 6, and the high pressure gas passes through this gap to form a gas discharge part. , 14 side, and the high pressure gas is thus dissipated and discharged to the valve body 8.
When the suppressing force on the folded portion 16 is released, the folded portion 16 returns to the original base film 6 due to its own elastic force.
The first circular hole 9 is then closed.

As shown in FIG. 3, the gas venting valve 5 is constructed by connecting the adhesive layer 1o of the base film 6 to the sealed packaging bag 1 so that the gas venting portion 3 and the circular hole 9 communicate with each other. As a result, the valve body 8 normally closes the circular hole 9, and the inside of the sealed packaging bag 1 is completely sealed. When the internal pressure of the packaging bag 1 increases, this high-pressure gas passes through the slit 4 that constitutes the gas venting part 3 of the packaging bag 1, and presses the folded part 16 of the valve body 8 through the circular hole 9 of the base film 6. However, as described above, a gap is formed between the valve body 8 and the base film 6, and the leakage of the packaging bag 1 is carried out through the released, unbonded both end edges 14, 14 of the cover film 7. This prevents an abnormal rise in internal pressure. In this case, the high-pressure gas inside the packaging bag 1 smoothly passes through the slits 4 and dissipates to the outside as described above, but the slits 4 are formed in a straight line and are arranged in parallel with each other at a predetermined interval. Therefore, the granular contents will not pass through the slit 4 and flow out to the circular hole 9 side together with the high pressure gas ejected from the slit 4.
Such passage of the granular contents is reliably blocked by the slit 4.

Therefore, accidents such as one granular content entering the circular hole 9 and pressing the folded part 16 of the valve body 8 or being caught between the folded part 16 and the base film 6 do not occur, and the valve body 8 reliably performs the above-mentioned valve function. Furthermore, when the packaging material is in the form of a film, it is made up of multiple slits, so the internal pressure causes the band of film between the slits to lift slightly, allowing gas to flow out smoothly. be.

In addition, in the present invention, the configuration of the gas vent valve is not limited to that of the embodiment described above; it covers the gas venting part and normally closes the gas venting part, and when the internal pressure inside the package increases, the gas venting valve closes the gas venting part. It is possible to use any gas vent valve having a configuration for opening the gas vent valve, and various changes may be made to other configurations without departing from the gist of the present invention.
