Abstract
Description
本発明は、消臭剤や脱臭剤（以下、総称して消臭剤と称する）などの消臭性能の評価方法に関し、例えば、生ごみや使用済みの紙おむつなどを入れる専用の消臭袋や、消臭機能を持たない袋の中に入れて使用する消臭剤による消臭性能を評価する方法に関する。 The present invention relates to a method for evaluating deodorizing performance such as a deodorant and a deodorant (hereinafter collectively referred to as a deodorant), for example, a dedicated deodorizing bag for putting garbage or used paper diapers, etc. The present invention relates to a method for evaluating the deodorizing performance of a deodorant used in a bag having no deodorizing function.
従来、種々の臭いを消す消臭剤として、液体タイプ、ゲルタイプ、または活性炭など固形タイプのものが知られている。消臭剤は、消臭剤をそのまま使用する場合と、紙などの担体に消臭剤を担持させて使用する場合がある。或いは、生ごみや使用済み紙おむつなどを入れるごみ袋自体に消臭機能を持たせたものも知られている。 Conventionally, as a deodorant for eliminating various odors, a liquid type, a gel type, or a solid type such as activated carbon is known. The deodorant may be used as it is, or may be used with a deodorant supported on a carrier such as paper. Or what gave the deodorizing function to the garbage bag itself which puts garbage, a used paper diaper, etc. is also known.
一般に、家庭から出る生ごみや使用済み紙おむつなどの可燃ごみは、専用のごみ袋に入れてごみ収集所に出す。可燃ごみは、地域ごとに指定されたごみの収集日まで、屋外のごみ容器に入れて放置したり、台所のごみ箱内にそのまま、或いはレジ袋などに入れて放置したりする。また、乳幼児や要介護者などが使用した紙おむつは、外出先で捨てることができない場合、専用のごみ袋やレジ袋に入れてしばらく持ち歩かなければならない。 In general, combustible waste such as household garbage and used paper diapers are put in a special garbage bag and sent to a garbage collection point. Combustible waste is left in an outdoor waste container, left in a kitchen waste bin, or left in a plastic bag, etc. until the designated garbage collection date for each region. Also, disposable diapers used by infants and other care recipients must be carried for a while in a special garbage bag or shopping bag if they cannot be thrown away.
しかし、ごみ袋やレジ袋は、一般に、ポリエチレンなどの比較的薄い素材により形成されており、小さな穴が開いている場合もあるため、袋の口を単に縛っただけでは、臭いが外部に漏れやすい。このため、臭いが外部に漏れにくい消臭袋が知られている。 However, garbage bags and plastic bags are generally made of a relatively thin material such as polyethylene, and there are cases where small holes are opened. Cheap. For this reason, a deodorizing bag is known in which the odor hardly leaks outside.
例えば、特許文献１には、リグニンスルホン酸塩とプラスチックを混合した組成物を含む素材により形成した消臭袋について開示されている。この消臭袋は、素材自体が消臭機能を有している。この消臭袋は、例えば、以下のようにその消臭性能の評価がなされている。 For example, Patent Document 1 discloses a deodorizing bag formed of a material containing a composition in which lignin sulfonate and a plastic are mixed. In this deodorizing bag, the material itself has a deodorizing function. For example, the deodorizing performance of this deodorizing bag is evaluated as follows.
まず、一般家庭から排出される生ごみ（野菜くず、残飯、調理粕など）１Ｋｇをポリ容器内で一週間放置し、その後、その生ごみを２００ｇずつ消臭袋に入れてしばらく放置する。そして、３日後、一週間後、二週間後のそれぞれにおいて、悪臭防止法に基づいて悪臭の規制基準等に用いられる６段階臭気強度表示法により、消臭袋の臭いを評価する。 First, 1 Kg of garbage (vegetable waste, leftovers, cooked rice cake, etc.) discharged from a general household is left in a plastic container for a week, and then 200 g of the garbage is placed in a deodorizing bag for a while. Then, after three days, one week, and two weeks later, the odor of the deodorizing bag is evaluated by a six-step odor intensity display method used for malodor control standards based on the malodor control method.
また、特許文献２には、酸性脱臭剤を含むプラスチックフィルム、塩基性脱臭剤を含むプラスチックフィルム、および物理的吸着による脱臭剤を含むプラスチックフィルムのうち少なくとも２種類のフィルムを組み合わせた消臭袋について開示されている。この消臭袋も、素材自体が消臭機能を有する。この消臭袋は、例えば、以下のようにその消臭性能の評価がなされている。 Patent Document 2 discloses a deodorizing bag in which at least two kinds of films are combined among a plastic film containing an acidic deodorant, a plastic film containing a basic deodorizer, and a plastic film containing a deodorizer by physical adsorption. It is disclosed. In this deodorizing bag, the material itself has a deodorizing function. For example, the deodorizing performance of this deodorizing bag is evaluated as follows.
まず、評価対象となるフィルムを２０ｃｍ×３０ｃｍのサイズに切ったフィルム片を複数枚用意し、それぞれ臭いを発する物質が入った複数のバイアル瓶に１枚ずつ入れて瓶を密閉する。そして、各バイアル瓶内の臭い成分を所定時間ごとに経時的に測定し、フィルム片の消臭性能を評価する。 First, a plurality of film pieces obtained by cutting a film to be evaluated into a size of 20 cm × 30 cm are prepared, and each film is put in a plurality of vials each containing a substance that emits odor, and the bottles are sealed. And the odor component in each vial bottle is measured with time for every predetermined time, and the deodorizing performance of a film piece is evaluated.
上述したように、消臭機能を有する袋に臭いを発する物質を収容した場合、袋の外に臭いが漏れ難くなる。しかし、上述した特許文献１の消臭袋は、官能的評価法により消臭性能が定性的に評価されており、消臭性能の定量的な評価にはなっていない。また、上述した特許文献２の消臭袋は、袋の形態での評価がなされておらず、実際に袋から外部にもれる臭い成分を測定している訳ではない。つまり、従来は、臭いを発する物質を袋に入れた形態で、袋の外に漏れる臭い成分を測定しておらず、このような形態における消臭性能が適切に評価されていない。 As described above, when a substance that emits odor is contained in a bag having a deodorizing function, the odor hardly leaks out of the bag. However, the deodorizing bag of Patent Document 1 described above is qualitatively evaluated for deodorizing performance by a sensory evaluation method, and is not quantitatively evaluated for the deodorizing performance. Moreover, the deodorizing bag of the above-mentioned Patent Document 2 has not been evaluated in the form of a bag, and does not actually measure odorous components that escape from the bag. That is, conventionally, odor components leaking out of the bag are not measured in a form in which a odorous substance is put in the bag, and the deodorizing performance in such a form is not properly evaluated.
本発明は、上記の点に鑑みてなされたもので、臭いを発する物質を収容した消臭機能を有する袋、及び消臭機能を持たない袋に臭いを発する物質とともに入れて使用する消臭剤による消臭性能を正確に評価することができる消臭性能の評価方法を提供することを目的とする。 The present invention has been made in view of the above points, and is a bag having a deodorizing function that contains a substance that emits odor, and a deodorant that is used together with a substance that generates odor in a bag that does not have a deodorizing function.

以下、本発明の実施形態について図面を参照して説明する。
図１は、実施形態に係る評価装置１００を示す概略図である。評価装置１００は、臭いを発する物質（以下、臭気物質とする）と消臭剤を収容した袋１０（評価対象袋）を入れるエアバッグ２０（第１、第２チャンバー）を有する。エアバッグ２０は、例えば、１０Ｌの容積を有する。エアバッグ２０は、臭いを透過させることのない素材により形成されている。エアバッグ２０内には、内部の空気を撹拌するためのファン２２が取り付けられている。エアバッグ２０は、袋１０を入れた後、図示しない開口部を閉じて密閉される。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic diagram illustrating an evaluation apparatus 100 according to the embodiment. The evaluation apparatus 100 includes an airbag 20 (first and second chambers) for storing a bag 10 (evaluation target bag) containing a substance that emits odor (hereinafter referred to as an odor substance) and a deodorant. The airbag 20 has a volume of 10 L, for example. The airbag 20 is formed of a material that does not transmit odor. A fan 22 for agitating the internal air is attached in the airbag 20. After the bag 10 is inserted, the airbag 20 is sealed by closing an opening (not shown).
評価装置１００は、連通管３２を介してエアバッグ２０に接続した検知管３０を有する。検知管３０の連通管３２と反対側の端部には、吸引器３４が取り付けられている。検知管３０の端部に吸引器３４を取り付けて、検知管３０の端部を切断し、吸引器３４のピストンアーム３６を図示右方に引くと、連通管３２を介してエアバッグ２０内の空気が検知管３０に流入する。ピストンアーム３６を引く量を調整することで、検知管３０に流入する空気の量を適量にコントロールすることができる。 The evaluation apparatus 100 includes a detection tube 30 connected to the airbag 20 via the communication tube 32. A suction device 34 is attached to the end of the detection tube 30 opposite to the communication tube 32. A suction device 34 is attached to the end of the detection tube 30, the end of the detection tube 30 is cut, and when the piston arm 36 of the suction device 34 is pulled to the right in the figure, the inside of the airbag 20 is connected via the communication tube 32. Air flows into the detection tube 30. By adjusting the amount by which the piston arm 36 is pulled, the amount of air flowing into the detection tube 30 can be controlled to an appropriate amount.
連通管３２は、連通管３２を通して空気を流通可能にするとともに空気の流通を遮断することができる図示しない開閉弁を備えている。開閉弁は、コック３８を回すことにより操作することができる。 The communication pipe 32 includes an on-off valve (not shown) that allows air to flow through the communication pipe 32 and blocks air flow. The on-off valve can be operated by turning the cock 38.
エアバッグ２０や袋１０の素材は、臭いや香りを吸脱着しない素材を用いることが望ましい。例えば、フッ素樹脂（ポリフッ化ビニル、ＦＲＰなど）、ポリエステル（ＰＥＴなど）、アルミニウム（アルミ薄膜にプラスチックフィルムをラミネートしたものなど）が適している。 As the material of the airbag 20 or the bag 10, it is desirable to use a material that does not absorb and desorb odors and fragrances. For example, a fluororesin (polyvinyl fluoride, FRP, etc.), polyester (PET, etc.), and aluminum (a laminate of a plastic film on an aluminum thin film) are suitable.
検知管３０は、例えば、ガラス管の中に一定量の検知剤を充填したものである。検知剤は、測定対象となるガスとの間の化学反応によって色が変わる薬剤であり、精製されたシリカゲル、活性アルミナ、ガラス粒などに試薬を吸着させて乾燥したものなどが用いられる。検知剤は、測定対象となるガスの種類に応じて選択される。 The detection tube 30 is, for example, a glass tube filled with a certain amount of detection agent. The detection agent is an agent whose color changes due to a chemical reaction with a gas to be measured, and a product obtained by adsorbing a reagent on purified silica gel, activated alumina, glass particles, or the like is used. The detection agent is selected according to the type of gas to be measured.
臭気物質としては、特に限定されないが、例えば、アンモニア、硫化水素、メチルメルカプタン、酢酸などがあり、これらの物質を単独で、或いは混ぜたものを使用することができる。また、一般的な生ごみや使用済み紙おむつなどを臭気物質として使用してもよい。 The odor substance is not particularly limited, and examples thereof include ammonia, hydrogen sulfide, methyl mercaptan, acetic acid, and the like. These substances can be used alone or in combination. Moreover, you may use a general garbage, a used paper diaper, etc. as an odor substance.
以下、上述した評価装置１００を用いて、臭気物質と共に袋１０に入れた消臭剤による消臭性能を評価する方法について説明する。なお、ここでは、袋１０の種類や枚数、消臭剤の種類や有無などの条件を変えて、複数の袋１０のサンプル（試料１〜試料７）を用意し、一定時間ごとに各サンプルの臭い成分を測定した。 Hereinafter, a method for evaluating the deodorizing performance of the deodorant placed in the bag 10 together with the odorous substance using the evaluation apparatus 100 described above will be described. Here, by changing conditions such as the type and number of bags 10 and the type and presence or absence of deodorant, a plurality of samples (samples 1 to 7) of the bags 10 are prepared. The odor component was measured.
まず、直径９０ｍｍのろ紙を複数枚用意し、各ろ紙に０．５ｗｔ％のアンモニア水溶液（約０．３ｇ）をスプレーで塗布し、複数の悪臭発生源（臭いを発する物質：臭気物質）を作成した。そして、下の［表１］に示した数種類の袋に上記の悪臭発生源と共に［表１］の消臭剤を入れ（或いは入れずに）、袋の開口部を閉じて試料１〜７を用意した。なお、各袋の中の空気の量は、袋の容積に対して８割程度とした。 First, prepare a plurality of filter papers with a diameter of 90 mm, and apply 0.5 wt% aqueous ammonia solution (about 0.3 g) to each filter paper by spraying to create multiple malodorous sources (odorous substances: odorous substances). did. And the deodorizer of [Table 1] is put into the several kinds of bags shown in [Table 1] below together with the above-mentioned malodor generating source (or not), the opening of the bag is closed, and samples 1 to 7 are Prepared. The amount of air in each bag was about 80% of the bag volume.
［表１］における乳白色袋は、ＨＤＰＥ（高密度ポリエチレン）製の袋（縦４４４ｍｍ×横５４９ｍｍ×厚さ０．０１９ｍｍ）であり、脱臭袋Ａは、Ｓ社製の「おむつの消臭袋」であり、脱臭袋Ｂは、Ｋ社製の「おむつが臭わない袋」である。また、［表１］における消臭剤の製品Ａは、エステー株式会社製の「脱臭炭におい取り紙」であり、試作品Ｂは、活性炭を担持させたクレープ紙である。 The milky white bags in [Table 1] are HDPE (high density polyethylene) bags (length 444 mm × width 549 mm × thickness 0.019 mm), and the deodorizing bag A is a “diaper deodorizing bag” manufactured by S Company. The deodorizing bag B is a “bag that does not smell diapers” manufactured by K company. Further, the deodorant product A in [Table 1] is “deodorized charcoal odor paper” manufactured by Este Co., Ltd., and prototype B is a crepe paper carrying activated carbon.
つまり、［表１］の試料１は、乳白色袋に悪臭発生源だけを入れて密閉した比較対象袋であり、試料２は、２枚重ねた乳白色袋に悪臭発生源だけを入れて密閉した参考袋であり、試料３は、乳白色袋に悪臭発生源と共に製品Ａ（表面積約４００ｃｍ２、９８ｍｍ×４０９ｍｍ）を入れて密閉した評価対象袋であり、試料４は、乳白色袋に悪臭発生源と共に試作品Ｂ（表面積約４００ｃｍ２、２００ｍｍ×２００ｍｍ）を入れて密閉した評価対象袋であり、試料５は、直径１ｍｍ程度の穴を１つ開けた乳白色袋に悪臭発生源と共に試作品Ｂ（表面積約４００ｃｍ２、２００ｍｍ×２００ｍｍ）を入れて密閉した評価対象袋であり、試料６は、脱臭袋Ａに悪臭発生源だけを入れて密閉した評価対象袋であり、試料７は、脱臭袋Ｂに悪臭発生源だけを入れて密閉した評価対象袋である。 That is, Sample 1 in [Table 1] is a comparative bag in which only a malodor generating source is put in a milky white bag and sealed, and Sample 2 is sealed in which only a malodor generating source is put in a two-layered milky white bag. Sample 3 is an evaluation target bag sealed with product A (surface area: about 400 cm 2 , 98 mm × 409 mm) together with a malodor source in a milky white bag, and sample 4 is a sample with a malodor source in a milky white bag. Sample B is an evaluation bag sealed with work B (surface area of about 400 cm 2 , 200 mm × 200 mm). Sample 5 is a prototype B (surface area of about surface area) in a milky white bag with a hole with a diameter of about 1 mm and a malodor source 400 cm 2 , 200 mm × 200 mm) and sealed, the sample 6 is a bag to be evaluated and sealed with only the odor generating source in the deodorizing bag A, and the sample 7 has a bad odor in the deodorizing bag B The source To be evaluated bag was sealed put.
次に、上記のように用意した複数の試料１〜７を、それぞれ、容積１０リットルの別々のエアバッグ２０内に収容した。その後、それぞれのエアバッグ２０内を、活性炭とシリカゲルで濾過した無臭の空気で満たした。さらに、各エアバッグ２０内の温度を一定に保持して、ファン２２を回転させて各エアバッグ２０内の空気を撹拌した。 Next, the plurality of samples 1 to 7 prepared as described above were accommodated in separate airbags 20 each having a volume of 10 liters. Thereafter, each airbag 20 was filled with odorless air filtered with activated carbon and silica gel. Furthermore, the air in each airbag 20 was stirred by rotating the fan 22 while keeping the temperature in each airbag 20 constant.
そして、下の［表２］に示した経過時間（０．１６ｈ、１ｈ、１．５ｈ、３ｈ、６ｈ、２４ｈ）ごとに、試料１〜７を入れた複数のエアバッグ２０内の空気を検知管３０で採取し、アンモニア濃度を測定した。なお、試料１〜７の他に、袋も消臭剤も入れずに悪臭発生源だけをエアバッグ２０内に収容したブランクを用意し、同じ経過時間ごとにアンモニア濃度を測定した。測定結果を下の［表２］に示す。 And the air in the several airbag 20 which put the samples 1-7 was detected for every elapsed time (0.16h, 1h, 1.5h, 3h, 6h, 24h) shown in the following [Table 2]. The sample was collected with a tube 30 and the ammonia concentration was measured. In addition, the blank which accommodated only the bad odor generation source in the airbag 20 without putting a bag and a deodorizer other than the samples 1-7 was prepared, and the ammonia concentration was measured for every same elapsed time. The measurement results are shown in [Table 2] below.
［表２］から分かるように、総合評価が「×」であった試料１、試料２、試料７については、２４時間経過した時点で、エアバッグ２０内のアンモニア濃度がブランクのアンモニア濃度と同程度となった。つまり、袋に悪臭発生源だけを入れて消臭剤を入れなかった場合には、例え脱臭袋Ｂを用いた場合であっても、消臭性能が長時間持続しないことが分かった。 As can be seen from [Table 2], for Sample 1, Sample 2, and Sample 7 with an overall evaluation of “x”, the ammonia concentration in the airbag 20 was the same as the blank ammonia concentration after 24 hours. It became about. In other words, it was found that when only the malodor generating source was put in the bag and no deodorant was added, even if the deodorizing bag B was used, the deodorizing performance did not last for a long time.
また、総合評価が「○」であった試料３（評価対象袋）については、２４時間経過した時点でも、エアバッグ２０内のアンモニア濃度がブランクのアンモニア濃度の半分以下であった。つまり、試料１（比較対象袋）と比較すると、悪臭発生源と共に製品Ａを袋に入れることで、悪臭が経時的に袋の外に漏れる量を大幅に低減することができているのが分かった。 For sample 3 (evaluation target bag) with a comprehensive evaluation of “◯”, the ammonia concentration in the airbag 20 was less than half the ammonia concentration of the blank even when 24 hours passed. In other words, when compared with Sample 1 (comparison target bag), it can be seen that the amount of malodor that leaks out of the bag over time can be greatly reduced by putting product A together with the malodor source in the bag. It was.
さらに、総合評価が「◎」であった試料４、試料５、試料６については、２４時間経過した時点でも、悪臭が袋の外に漏れることはほとんど無かった。つまり、製品Ａの消臭性能をさらに改良した試作品Ｂを消臭剤に用いた場合、長時間経っても袋の外に悪臭が漏れることはほとんど無く、高い消臭性能を示すことが分かった。 Further, for sample 4, sample 5, and sample 6 with a comprehensive evaluation of “◎”, even when 24 hours had passed, there was almost no odor leaking out of the bag. In other words, it was found that when prototype B, which further improved the deodorant performance of product A, was used as a deodorant, it did not leak badly outside the bag even after a long time and showed high deodorant performance. It was.
以上のように、本実施形態によると、悪臭発生源と共に消臭剤を袋１０に入れて、この袋１０をエアバッグ２０内に収容配置して、一定時間経過した時点で、エアバッグ２０内の空気を採取して臭いを評価するようにしたため、袋１０の外に経時的に漏れる悪臭を正確に評価することができる。これに対し、例えば、悪臭発生源と消臭剤を袋に入れずにエアバッグ２０内に収容配置した場合、比較的広い容積を有するエアバッグ２０内で一旦拡散した臭いを消臭剤が消臭することになり、袋から漏れる臭いを適切に評価することはできない。 As described above, according to the present embodiment, the deodorant is put in the bag 10 together with the malodor generation source, and the bag 10 is accommodated and disposed in the airbag 20. Since the air was collected and the odor was evaluated, the bad odor leaking out of the bag 10 with time can be accurately evaluated. On the other hand, for example, when a malodor generation source and a deodorant are accommodated in the airbag 20 without being put in a bag, the deodorizer removes the odor once diffused in the airbag 20 having a relatively large volume. The odor leaking from the bag cannot be properly evaluated.
なお、本実施形態によると、悪臭発生源と共に袋１０に入れた消臭剤の消臭性能を適切に評価することができるとともに、袋自体の消臭性能も適切に評価することができる。この場合、評価対象となる「袋」は、消臭機能を有する消臭袋であってもよく、レジ袋などの消臭機能を持たない袋であってもよい。 In addition, according to this embodiment, while being able to evaluate appropriately the deodorizing performance of the deodorizer put into the bag 10 with the malodor generating source, the deodorizing performance of the bag itself can also be evaluated appropriately. In this case, the “bag” to be evaluated may be a deodorizing bag having a deodorizing function or a bag having no deodorizing function, such as a shopping bag.
