1231177 玖、發明說明 【發明所屬之技術領域】 本發明係關於以驅除害蟲及防菌防黴用之用於煙燻劑 充塡容器的發熱體保持板及其製造方法，暨具有該發熱體 保持板爲特徵的.煙燻劑充塡容器。 【先前技術】 作爲在室內等密閉空間內驅除害蟲和進行防菌防黴處 理的手段，煙燻劑被廣泛地使用，而充塡這樣的煙燻劑的 煙燻劑充塡容器也已經實用化。 上述煙燻劑充塡容器一般如圖6和圖7所示，由容納煙 燻劑104的收容部分103和上蓋102組成的金屬容器構成。 在上蓋102上設有用於露出點火用發熱體1〇5的點火頭 106的中央孔107和多個噴煙孔（未圖示），而在該上蓋102 上安裝著裝有點火用發熱體105的發熱體保持板108。 並且’在發熱體保持板108上，形成有裝有點火用發熱 體105的安裝孔109和多個噴煙孔（未圖示），此安裝孔1〇9 周邊部向上立起，以便能夠保持點火用發熱體1 〇 5。 如上所述的煙燻劑充塡容器通常是在嵌有紙管等耐熱 性外筒的狀態下’例如收容在合成樹脂製造的外裝容器內 的狀態下使用。 【發明內容】 (發明所欲解決之問題） 如圖6和圖7所示的煙燻劑充塡容器，通過用摩擦板摩 擦點火用發熱體105的點火頭ι〇6來點火，由此使點火用 發熱體內部的發熱劑燃燒，由產生的熱量使煙燻劑1 〇 4發 7 312/發明說明書(補件)/92-06/92107727 1231177 煙，通過發熱體保持板108和上蓋102的噴煙孔將煙釋放 到外部。 但是，安裝著現有點火用發熱體1 05的發熱體保持板 1 08，使用的是整個面上有多個穿孔（有孔金屬板）’或未加 工的金屬板的圓盤狀物體，在前一種情況下’在其中心部 位形成的安裝孔的周圍，形成任意形狀的孔（上述多個孔爲 與安裝孔形成一體的任意形狀的孔），在後一種情況下’安 裝孔是單純的圓形。 因此，在安裝孔1 0 9的周邊部向上立起的情況下，在前 者的例子中，爲了防止安裝點火用發熱體1〇5時，插入強 度增大、發熱體保持板1 0 8變形，有必要加厚板的厚度’ 這對降低材料成本是不利的。在後者的例子中，由於安裝 孔周邊部的向上立起部幾乎不可能有彈性地擴大孔徑’與 安裝點火用發熱體105時需要很大的力相反，在用摩擦板 摩擦點火用發熱體105的點火頭106進行點火時，具有點 火用發熱體105易於從安裝孔109中脫落的問題。 本發明之目的在於，提供一種以解決上述先前技術所具 有的問題，通過使板材的厚度變薄而實現材料成本降低， 同時，以具有能提高所安裝的點火用發熱體的保持力的新 型結構的發熱體保持板，以及能夠高效地製造這樣的發熱 體保持板的製造方法，和具有該發熱體保持板爲特徵的煙 燻劑充塡容器。 (解決問題之手段） 爲了實現如上目的而完成的本發明之構成，如下所述。 即，本發明的發熱體保持板具有如下的特徵，在固定於 8 312/發明說明書(補件)/92-06/92107727 1231177 充塡了煙燻劑的容器內的發熱體保持板上具有安裝煙燻劑 點火用發熱體的安裝孔和多個噴煙孔， 在上述安裝孔的周邊部，形成有由多個分割溝大致等間 隔地分離的多個可彈性地擴大孔徑的彎曲支持片。 按照上述本發明的發熱體保持板，由多個分割溝大致等 間隔地分離的多個可彈性地擴大孔徑的彎曲支持片形成於 安裝孔的周邊部。而且多個支援片的數目較佳是2〜20 個，更佳是3〜9個。 由於可彈性地擴大孔徑的支援片可以吸收安裝點火用 發熱體時的力，所以使用196N(20kgf)以下，平均98N(10kgf) 左右的力可以容易地將點火用發熱體安裝在發熱體保持板 的安裝孔上。 另外，由於要使點火用發熱體脫落，根據支援體的彈 力，需要98N(10kgf)以上的載荷，能夠保持很高的保持力， 所以在用摩擦板摩擦點火用發熱體的點火頭進行點火時， 就能夠防止點火用發熱體由安裝孔中脫落。另外能夠根據 點火用發熱體的形狀適當設計上述支持片彎曲的方向和角 度。 保持在本發明的發熱體保持板上的點火用發熱體，在安 裝到發熱體保持板的安裝部的周邊部具有多個突起部，該 突起部較佳爲數量多於上述多個分割溝。按照如此的結 構，在將點火用發熱體安裝到發熱體保持板的安裝孔中 時，即使點火用發熱體的上述突起部和發熱體保持板的分 割溝互相並非完全一致地對應，也能夠有效地提高點火用 發熱體的保持力。 9 31万發明說明書(補件)/92-06/92107727 1231177 上述多個噴煙孔以上述安裝孔爲中心而形成，而且，在 這些噴煙孔的周圍，較佳形成有突起狀的剛性補強部。按 照這樣的結構，由於上述突起部能夠有效地補強因形成多 個噴煙孔而降低了的發熱體保持板的平面剛性，所以能夠 使發熱體保持板的厚度變薄，從而降低製造成本。另外， 形成於上述噴煙孔周圍的突起狀剛性補強部，只要能夠有 效地補強發熱體保持板，對其形態就沒有特別的限制，例 如可在多個噴煙孔之間形成多個突起部；在噴煙孔的周 圍，在同心圓上形成一個以上的環狀突起部；在噴煙孔的 周圍形成一連串的突起部。 本發明包括以具有上述本發明發熱體保持板爲特徵的 煙燻劑充塡容器。 另外，本發明的發熱體保持板之製造方法是用於製造具 有安裝煙燻劑點火用發熱體的安裝孔、以該安裝孔爲中心 形成的多個噴煙孔和形成於該噴煙孔周圍的突起狀剛性補 強部的、被固定在充塡有煙燻劑的容器內的發熱體保持板 的方法， 其特徵在於，具有= 在由卷材製成的基板上，在周邊部以大致相等的間隔形 成具有多個分割溝的上述安裝孔，同時形成一部分上述多 個噴煙孔的第一步驟； 使由發熱體保持板的外形部以及上述分割溝分離的安 裝孔的周邊部彎曲，同時形成上述剛性補強部的第二步驟； 形成其餘的上述多個噴煙孔的第三步驟； 由上述基板抽出位於上述外形部發熱體保持板的第四 10 312/發明說明書(補件)/92-06/92107727 1231177 步驟。 並且’本發明中的卷材，是指由無錫薄鋼板、鍍鋅鋼板、 不銹鋼板、鋁板、鍍錫鋼板等金屬成型爲卷狀的金屬板。 並且’本發明的另一種發熱體保持板之製造方法是用於 製造具有安裝煙燻劑點火用發熱體的安裝孔、以該安裝孔 爲中心形成的多個噴煙孔和形成於該噴煙孔周圍的突起狀 剛性補強部的、被固定在充塡有煙燻劑的容器內的發熱體 保持板的方法， 其特徵在於，具有： 在由卷材製成的基板上，在周邊部以大致相等的間隔形 成具有多個分割溝的上述安裝孔，同時形成一部分上述多 個噴煙孔的第一步驟； 使發熱體保持板的外形部彎曲，同時形成上述剛性補強 部的第二步驟； 在彎曲由上述分割溝分離的安裝孔的周邊部的同時，形 成其餘上述多個噴煙孔的第三步驟；以及 從上述基板抽出位於上述外形部的發熱體保持板的第 四步驟。 按照上述本發明的製造方法，特別通過分別在第一步驟 和第三步驟中形成多個噴煙孔，可使各步驟中所用的模具 進一步簡化，能夠提高其耐久性。並且，由於在由第一步 驟形成安裝孔和一部分噴煙孔的基板上，由第二步驟形成 剛性補強部，提高了基板的平面剛性，因而就可防止在第 三步驟中形成其餘噴煙孔時基板的變形，能夠連續而高效 地製造符合設計的製品。 11 312/發明說明書(補件)/92-06/92107727 1231177 【實施方式】 下面說明本發明的實施形態例，但本發明不限於這些例 子。 首先，參照圖1和圖2說明本發明的發熱體保持板。 圖1爲顯示裝有本發明的發熱體保持板的煙燻劑充塡容 器一個例子的局部切口剖面圖。圖2爲顯示此發熱體保持 板的示意圖，（a)爲俯視圖，（b)爲沿著（a)中的A-A’線所作 的部分剖面圖，（c)爲（b)中B的局部放大圖。 如圖1和圖2所示，本實施例的煙燻劑充塡容器1主要 是由容納煙燻劑4的收容部3和上蓋2組成的金屬容器構 成。 在上蓋2的上面，設有露出點火用發熱體5的點火頭6 的中央孔7以及多個噴煙孔（未圖示），而在上蓋2的內側， 安裝著裝有點火用發熱體5的發熱體保持板8。 在發熱體保持板8的中央，形成有安裝點火用發熱體5 用安裝孔9，在該安裝孔9的周邊部，等間隔地形成多個（在 本實施例中是5個）呈半圓形的分割溝1 〇。因此，由這些 分割溝10分離的安裝孔9的周邊部，在上方彎曲成一定的 角度（在本實施例中是大約77°)地形成多個支持片11。 並且，這些支持片所彎曲的角度，較佳不到90 °，更佳 在50 °以上但不到90 °。 如上所述呈錐狀彎曲的多個支持片1 1，由於在由安裝孔 9的下方安裝點火用發熱體5時可彈性地擴大孔徑，因此 使用較小的力就能夠安裝點火用發熱體5，同時，能夠在 安裝後利用其彈力有效地支持點火用發熱體5。關於這一 12 312/發明說明書(補件)/92-06/92107727 1231177 點，用幾個試驗結果進行更加詳細的說明。 表1表示在本實施例的發熱體保持板8和現有的發熱體 保持板（使用有孔金屬板和未加工金屬板）上安裝點火用發 熱體5時的插入強度和發熱體保持板有無變形、以及安裝 的點火用發熱體的脫落強度和點火時有無脫落的試驗結 果。並且，表1中的插入強度和脫落強度的測定方法如下。 (插入強度的測定） 將點火用發熱體插入發熱體保持板的安裝孔，由 Strogiraph(試驗速度100mm/min)測定的安裝在適當位置時 所需的最大載荷。 (脫落強度的測定） 由Strograph(試驗速度100mm/min)測定的使安裝在發熱 體保持板上的點火用發熱體由安裝孔脫落（包括沒有脫落 時使發熱體保持板變形的情況）所需的最大載荷。 13 312/發明說明書(補件)/92-06/92107727 1231177 點火時 脫落 摧 摧 联 摧

不僅可以在插入強度最大不過在196N(20kgf)以下，平均在 98N(l〇kgf)以下的較小載荷下安裝點火用發熱體5,而且在 安裝後要使其脫落的情況下，所需的彈力要在98N(10kgf) 以上。 並且，沒有看到在插入時安裝孔9變形，和安裝後由於 在點火頭6的上部以強力壓住的擦火動作而造成的點火用 發熱體5的脫落。 而在習知技術中，在有孔金屬板的情況下，插入強度最 大是314N(3 2kg)，平均也需要225N(23kgf)，與本發明的發 熱體保持板相比，安裝點火用發熱體5時需要很大的載 荷。而由於在未加工金屬板的情況下，不僅最大需要 274N(28kgf)的載荷，幾乎完全沒有彈性，所以脫落強度是 ON (Okgf)，插入時安裝孔9的變形和安裝後由點火操作而 脫落的情況都有所發生。 在本實施例中將形成的半圓形切口部作爲分割溝ί 0，只 要這些分割溝能夠在安裝孔9的周邊部以大致等間隔地分 離，就沒有特別的限制，不僅限於切口部，也可以形成單 狹縫狀，而且也可以是由支援片形成的突起部與分割溝形 成的凹陷部形成連續的波紋狀。 另外，在本實施例的發熱體保持板8上，以安裝孔9爲 中心呈放射狀地形成多個（在本實施例中是1 5個）噴煙孔 12。在用摩擦板等摩擦點火用發熱體5的點火頭6進行點 火，然後使點火用發熱體內部的發熱劑燃燒，由該熱量使 煙燻劑4發煙時，這些噴煙孔1 2就是煙的釋出路。 15 312/發明說明書(補件)/92-06/92107727 1231177 在本實施例中，形成了 1 5個橢圓孔作爲噴煙孔1 2，這 樣的噴煙孔1 2的形狀和數目可根據發煙量進行適當的設 計。例如，其形狀可以是圓形、長方形、橢圓形或者它們 的任意組合形狀。而其數目可以是大約1〜30個。並且， 爲了使煙燻劑充塡容器1達到較佳的發煙狀態，噴煙孔12 的總開口面積與設於上蓋2上的多個噴煙孔（未圖示）的開 口面積之比較佳爲1〜8。 而且，在上述噴煙孔1 2之間，以相同的放射狀形成多個 突起狀的剛性補強部1 3，有效地對由於形成了多個噴煙孔 1 2而降低了的發熱體保持板8的平面剛性進行補強。過去 的發熱體保持板，一般使用厚度爲0.4mm以上的金屬板， 但通過在適當的位置上形成了這樣的剛性補強部1 3，就能 夠使用厚度0.3mm左右的金屬板。 在本實施例中，作爲剛性補強部1 3是在5個位置上形成 的橢圓結構，但這些剛性補強部1 3的形狀、位置和數目， 可在考慮發熱體保持板自身的強度和點火用發熱體的安 裝·保持力後進行適當的設計。但是，如在本實施例中以 安裝孔9爲中心呈放射狀形成多個噴煙孔的情況下，較佳 在這些噴煙孔之間均句地形成具有上述形狀的剛性補強 部，這樣就能夠極爲有效地提高發熱體保持板的平面剛性。 發熱體保持板8的周邊部1 4，如在圖2中所示是向下彎 折。該周邊部14除了易於安裝在發熱體保持板8的上蓋2 上以外，同時由於其彈力還可以防止其從上蓋2上脫落。 因此，在此周邊部1 4上可以同時使用例如黏合劑等以將其 固定在上蓋2上。 16 312/發明說明書(補件)/92-06/92107727 1231177 作爲保持於本發明的發熱體保持板上的點火用發熱體 5，如圖3所示，較佳在與發熱體保持板相接的安裝部1 5 的周圍，等間隔地形成多個突起部1 6。這樣的突起部1 6， . 可使點火用發熱體5更牢固地嵌合在發熱體保持板8的安 裝孔9中。在此情況下，所形成的這些突起部分1 6較佳爲 比上述分割溝1 0的數量還多。根據這樣的設計，在發熱體 保持板8的安裝孔9中安裝點火用發熱體5時，不管點火 用發熱體5的突起部分1 6和上述分割溝1 0互相之間是否 完全一致，都能夠以很高的保持力保持住點火用發熱體5。 ® 如上所述的煙燻劑充塡容器，例如，如圖4所示，在嵌 合了由紙管等組成的耐熱性外筒1 7的狀態下，以收容在由 合成樹脂等製成的外裝容器1 8內的狀態下使用。另外，圖 4中的1 9是外裝容器1 8的上蓋。 以下，參照圖5說明本發明的發熱體保持板之製造方法。 圖5爲連續表示本發明發熱體保持板之製造方法的一個 例子，即如圖2所示的發熱體保持板8的製造實施例。下 面按照步驟的順序說明本發明製造方法的特徵。 · (第一步驟） 在卷材基板50寬方向的中央形成安裝孔9，在其周邊部 大致等間隔地具有5個分割溝1 0，以此安裝孔9爲中心呈 - 放射狀地形成5個橢圓形噴煙孔1 2。並且，在本實施例中， . 爲了提高卷材基板50的送進精度，在基板50的兩側端部 附近同時形成圓形的定位孔5 1。這些定位孔5 1，在以後的 步驟中安裝有在上模具上尖端削細的導向銷，在衝床滑塊 下降的同時，使導向銷插入定位孔5 1中，從而確定卷材的 17 312/發明說明書(補件)/92-06/92107727 1231177 位置，提高了送進精度。導向銷的尖端插入定位孔5 1的瞬 間，卷材必須處於自由狀態，此時將通過送進裝置的夾子 對卷材的保持設爲開放狀態。 . (第二步驟） 將製得的發熱體保持板的外形部（周邊部1 4)以及由分割 溝10分離的安裝孔周邊部，按照一定的方向彎曲成錐體狀 形成支持片11，同時以安裝孔9爲中心呈放射狀地形成5 個突起部（剛性補強部13)。 (第三步驟） _ 以安裝孔9爲中心呈放射狀地形成其餘1 0個噴煙孔1 2。 發熱體保持板的噴煙孔有必要確保一定的面積以上，在 本實施例中形成的多個橢圓形噴煙孔位於互相靠近的位 置。因此要想一次就將所有噴煙孔脫模，就可能導致模具 耐久性降低的問題。但是通過將如上所述的多個噴煙孔12 的形成以互相之間保持一定距離地分別在第一步驟中和第 三步驟中形成的形態進行，就能夠提高模具的耐久性。 (第四步驟） 鲁 由基板50抽出位於外形部（周邊部14)發熱體保持板。由 此得到如圖2所示的發熱體保持板8。 這樣按照本發明的製造方法，特別是分別通過第一步驟 - 和第三步驟形成多個噴煙孔，能夠簡化各個步驟所用的模 _ 具構造提高其耐久性，同時，由於在第一步驟中在基板上 形成安裝孔和一部分噴煙孔，在第二步驟中在基板上形成 剛性補強部以致提高了基板的平面剛性，所以能夠在第三 步驟中形成其餘噴煙孔時防止基板的變形，從而能夠以優 18 312/發明說明書(補件)/92-06/92107727 1231177 良的效率製造符合設計的製品。 並且’在本發明的製造方法中，根據所製得的發熱體保 持板的孔徑，具體說，例如，在發熱體保持板的孔徑較大 的情況下，在第二步驟中進行的安裝孔周邊部的彎曲，也 可以在第三步驟中進行。因此有可能分散對基板造成的變 形和提高製品尺寸的精度。 按照如上所述的本發明發熱體保持板，通過形成有由多 個分割溝大致等間隔地分離的可彈性地擴大孔徑的彎曲支 持片，可均勻地支持點火用發熱體的周圍，同時，由於可 彈性地擴大孔徑的支援片能夠吸收安裝點火用發熱體時產 生的力，且由於能夠輕易地將點火用發熱體安裝在發熱體 保持板的安裝孔中，並由支持片的彈力能夠以很高的保持 力保持住點火用發熱體，所以在用摩擦板等摩擦點火用發 熱體的點火頭進行點火時，能夠有效地防止點火用發熱體 從安裝孔中脫落。 並且，特別是，由於將點火用發熱體安裝到發熱體保持 板上的安裝部的周圍具有多個突起部，當這些突起部比形 成於發熱體保持板的安裝孔周邊部的分割溝的數量還多的 情況下，上述突起部將使點火用發熱體更牢固地嵌合在發 熱體保持板的安裝孔中，從而能夠更有效地提高點火用發 熱體的保持力。 而且，特別是，多個噴煙孔是以安裝孔爲中心形成的， 例如呈放射狀，而且當在這些噴煙孔的周邊形成有呈橢圓 形、環形等突起狀剛性補強部時，由於形成多個噴煙孔而 降低的發熱體保持板的平面剛性可以由上述突起部分得到 19 312/發明說明書(補件)/92-06/92107727 1231177 有效地補強，使得發熱體保持板的厚度減薄成爲可能，並 能夠降低製造成本。 按照本發明的發熱體保持板之製造方法，由於多個噴煙 _ 孔是分別在第一步驟和第三步驟中形成的，所以在能夠簡 化各個步驟中所用的模具構造，提高其耐久性的同時，由 於在由第一步驟形成了安裝孔和一部分噴煙孔的基板上， 通過由第二步驟形成的剛性補強部提高了基板的平面剛 性，所以能夠防止在第三步驟中形成其餘的噴煙孔時的基 板的變形等。這樣，就能夠以良好的效率在較少的步驟中 φ 連續地製造出符合設計的製品。 【圖式簡單說明】 圖1爲顯示本發明之煙燻劑充塡容器一個例子的局部切 口剖面圖。 圖2(a)〜（c)爲顯示本發明之煙燻劑充塡容器中使用的 發熱體保持板的一個例子的示意圖。 圖3爲顯示適用於本發明的煙燻劑充塡容器的點火用發 熱體的一個例子的示意圖。 · 圖4爲顯示將圖1的煙燻劑充塡容器收納保持於外裝容 器中的狀態的部分剖面圖。 圖5爲說明本發明之發熱體保持板的製造方法一個例子 - 的圖。 ， 圖6爲習知煙燻劑充塡容器的剖面圖。 圖7爲圖6之煙燻劑充塡容器的分解圖。 (元件符號說明） 1 煙燻劑充塡容器 20 312/發明說明書(補件)/92-06/92107727 1231177 2 上蓋 3 收容部 4 煙燻劑 5 點火用發熱體 6 點火頭 7 中央孔 8 發熱體保持板 9 安裝孔 10 分割溝 11 支持片 12 噴煙孔 13 剛性補強部 14 發熱體保持板的周邊部 15 安裝部 16 突起部 17 耐熱性外筒 18 外裝容器 19 外裝容器的上蓋 50 基板（卷材） 5 1 定位孔 102 上蓋 1 0 3 收容部 104 煙燻劑 105 點火用發熱體 106 點火頭 211231177 发明 Description of the invention [Technical field to which the invention belongs] The present invention relates to a heating element holding plate for a smoker filling container for repellent of insects and bacteria and mold, and a method for manufacturing the same, and the heating element holding The plate features a fumigant-filled container. [Prior art] As a means of exterminating pests and carrying out antibacterial and mildew treatment in confined spaces such as indoors, fumigants are widely used, and fumigant filling containers filled with such fumigants have also been put into practical use. . As shown in Figs. 6 and 7, the above-mentioned smoking agent filling container is generally composed of a metal container composed of an accommodating portion 103 and an upper cover 102 for containing the smoking agent 104. The upper cover 102 is provided with a central hole 107 of the ignition head 106 for exposing the heating element 105 for ignition and a plurality of smoke spray holes (not shown). The upper cover 102 is mounted with heat generated by the heating element 105 for ignition.体 保护 板 108。 Body holding plate 108. In addition, the heating body holding plate 108 is formed with a mounting hole 109 in which a heating body 105 for ignition and a plurality of smoke spray holes (not shown) are formed, and the peripheral portion of this mounting hole 10 stands up so that the ignition can be maintained Use heating element 1 05. Such a fumigant-filled container as described above is usually used in a state in which a heat-resistant outer tube such as a paper tube is embedded ', for example, in a state of being housed in an external container made of synthetic resin. [Summary of the Invention] (Problems to be Solved by the Invention) The fumigant-filled container shown in FIG. 6 and FIG. 7 is ignited by rubbing the ignition head of the ignition heating element 105 with a friction plate to ignite, so that The heating agent inside the heating element for ignition is burned, and the smoke generated by the heat generating agent 104 is emitted 7 312 / Instruction Manual (Supplement) / 92-06 / 92107727 1231177 The smoke passes through the heating element holding plate 108 and the upper cover 102. The smoke vent releases smoke to the outside. However, the heating element holding plate 108 for mounting the existing heating element 105 for ignition uses a disc-shaped object having a plurality of perforations (perforated metal plates) 'or unprocessed metal plates on the entire surface. In one case, a hole of an arbitrary shape is formed around the mounting hole formed at the center thereof (the above-mentioned plurality of holes are holes of any shape integral with the mounting hole), in the latter case, the mounting hole is a simple circle shape. Therefore, in the case where the peripheral portion of the mounting hole 109 stands up, in the former example, in order to prevent the insertion strength from increasing when the heating element 105 for ignition is mounted, the heating element holding plate 108 is deformed. It is necessary to thicken the thickness of the plate ', which is disadvantageous for reducing the material cost. In the latter example, it is almost impossible to elastically expand the aperture due to the upwardly rising portion of the peripheral portion of the mounting hole. Contrary to the large force required when mounting the heating element 105 for ignition, the friction heating plate 105 is used to rub the heating element 105 for ignition. When the igniting head 106 is ignited, there is a problem that the heating element 105 for ignition is easily detached from the mounting hole 109. An object of the present invention is to provide a novel structure that can solve the problems of the above-mentioned prior art, reduce the material cost by reducing the thickness of the plate material, and improve the holding force of the mounted heating element for ignition. A heating element holding plate, a manufacturing method capable of efficiently producing such a heating element holding plate, and a fumigant-filled container having the heating element holding plate. (Means for Solving the Problems) The constitution of the present invention completed to achieve the above-mentioned object is as follows. That is, the heating element holding plate of the present invention has the following characteristics. The heating element holding plate is fixed to the heating element holding plate fixed in 8 312 / Invention Specification (Supplement) / 92-06 / 92107727 1231177 in a container filled with a fumigant. The mounting hole and the plurality of smoke spray holes of the heat generating body for the ignition of the smoke agent are formed at the peripheral portion of the mounting hole with a plurality of curved support pieces that can be elastically enlarged in diameter and separated by a plurality of divided grooves at substantially equal intervals. According to the heating element holding plate of the present invention described above, a plurality of curved support pieces capable of elastically expanding the apertures are formed at a peripheral portion of the mounting hole by a plurality of divided grooves separated at substantially equal intervals. In addition, the number of the plurality of supporting pieces is preferably 2 to 20, and more preferably 3 to 9. The support sheet that can elastically expand the aperture can absorb the force when mounting the heating element for ignition. Therefore, the heating element for ignition can be easily mounted on the heating element holding plate with a force of 196N (20kgf) or less and an average of about 98N (10kgf). Mounting holes. In addition, since the heating element for ignition is to be detached, a load of 98N (10kgf) or more is required according to the elastic force of the support body, and a high holding force can be maintained. Therefore, when the friction head is used to rub the ignition head of the ignition heating element for ignition, This prevents the ignition heating element from falling out of the mounting hole. In addition, the direction and angle of bending of the support sheet can be appropriately designed according to the shape of the heating element for ignition.

Therefore, a plurality of support pieces 11 are formed at the peripheral portion of the mounting hole 9 separated by these division grooves 10 and bent at a certain angle (about 77 ° in this embodiment) above. Moreover, the bending angle of these support pieces is preferably less than 90 °, and more preferably more than 50 ° but less than 90 °. As described above, the plurality of supporting pieces 11 that are bent in a tapered shape can elastically expand the aperture when the ignition heating element 5 is mounted below the mounting hole 9, so that the ignition heating element 5 can be mounted with a small force. At the same time, it can effectively support the ignition heating element 5 by using its elastic force after installation. This 12 312 / Invention Specification (Supplement) / 92-06 / 92107727 1231177 point will be explained in more detail with several test results. Table 1 shows the insertion strength and deformation of the heating element holding plate when the heating element 5 for ignition is mounted on the heating element holding plate 8 of the present embodiment and a conventional heating element holding plate (using a perforated metal plate and a raw metal plate). And the test results of the peeling strength of the mounted heating element for ignition and the presence or absence of peeling during ignition. The methods for measuring the insertion strength and the peeling strength in Table 1 are as follows. (Measurement of Insertion Strength) The maximum load required when the ignition heating element is inserted into the mounting hole of the heating element holding plate and measured at Strogiraph (test speed 100 mm / min) at an appropriate position. (Measurement of peeling strength) It is necessary to make the heating element for ignition mounted on the heating element holding plate fall off from the mounting hole (including the case where the heating element holding plate is deformed when it does not fall off) measured by Strograph (test speed 100mm / min).

The spring force must be 98N (10kgf) or more. Also, the mounting hole 9 is not deformed during insertion. And after the installation, the heating element 5 for ignition is detached due to the burning action which is strongly pressed on the upper part of the ignition head 6. In the conventional technology, in the case of a perforated metal plate, the maximum insertion strength is 314N (3 2kg), 225N (23kgf) is also required on average. Compared with the heating element holding plate of the present invention, a large load is required when installing the heating element 5 for ignition. However, in the case of a raw metal plate, not only the maximum A load of 274 N (28 kgf) is required, and there is almost no elasticity, so the peeling strength is ON (Okgf). The deformation of the mounting hole 9 during insertion and the case of falling off by the ignition operation after installation have occurred. In this embodiment, The formed semi-circular cutouts are divided grooves 0. As long as these divided grooves can be separated at approximately equal intervals in the peripheral portion of the mounting hole 9, there is no particular limitation, and it is not limited to the cutout portion, and a single slit shape may be formed. In addition, the protruding portion formed by the supporting sheet and the recessed portion formed by the dividing groove may form a continuous wave shape. In addition, the heating body holding plate 8 of this embodiment is provided with the mounting hole 9 as the center. A plurality of (15 in this embodiment) smoke injection holes 12 are formed in a radial pattern. The ignition head 6 of the ignition heating element 5 is rubbed with a friction plate or the like to ignite, and the heating agent inside the ignition heating element is burned. When the fumigant 4 emits smoke due to the heat, the smoke spray holes 12 are the smoke release path. 15 312 / Invention Specification (Supplement) / 92-06 / 92107727 1231177 In this embodiment, 15 elliptical holes are formed as the smoke spray holes 12. The shape and number of such smoke spray holes 12 can be determined according to the amount of smoke Design appropriately. For example, the shape may be circular, rectangular, oval, or any combination thereof. The number can be about 1 to 30. In addition, in order to make the smoking agent-filled container 1 achieve a better smoking state, the total opening area of the smoke injection hole 12 and the opening area of a plurality of smoke injection holes (not shown) provided on the upper cover 2 are preferably 1 ~8. In addition, a plurality of protruding rigid reinforcing portions 13 are formed in the same radial shape between the above-mentioned smoke spray holes 12, which effectively reduces the temperature of the heat-generating body holding plate 8 lowered by the formation of the plurality of smoke spray holes 12. Reinforcement in plane rigidity. Conventional heating element holding plates have generally used metal plates having a thickness of 0.4 mm or more. However, by forming such rigid reinforcing portions 13 at appropriate positions, metal plates having a thickness of about 0.3 mm can be used. In this embodiment, the rigid reinforcing portions 13 are elliptical structures formed at five positions. However, the shape, position, and number of these rigid reinforcing portions 13 can be considered in consideration of the strength of the heating body holding plate itself and its use for ignition. Appropriate design after mounting and holding force of the heating element. However, in the case where a plurality of smoke injection holes are formed radially around the mounting hole 9 in this embodiment, it is preferable to form rigid reinforcement portions having the above-mentioned shape uniformly between the smoke injection holes, so that it can be extremely Effectively improve the planar rigidity of the heating element holding plate. The peripheral portion 14 of the heat generating body holding plate 8 is bent downward as shown in FIG. 2. The peripheral portion 14 can be easily attached to the upper cover 2 of the heating body holding plate 8 and can also be prevented from falling off the upper cover 2 due to its elastic force. Therefore, for example, an adhesive or the like may be simultaneously applied to the peripheral portion 14 to fix it to the upper cover 2. 16 312 / Invention Manual (Supplement) / 92-06 / 92107727 1231177 As the ignition heating element 5 held on the heating element holding plate of the present invention, as shown in FIG. 3, it is preferably connected with the heating element holding plate Around the mounting portion 1 5, a plurality of protruding portions 16 are formed at equal intervals. Such a protruding portion 16 allows the ignition heating element 5 to be fitted into the mounting hole 9 of the heating element holding plate 8 more firmly. In this case, it is preferable that the number of the protruding portions 16 formed is larger than the number of the divided grooves 10 described above. According to such a design, when the ignition heating element 5 is mounted in the mounting hole 9 of the heating element holding plate 8, the projection portion 16 of the ignition heating element 5 and the above-mentioned divided grooves 10 can be completely consistent with each other, regardless of whether or not they are identical with each other. The ignition heating element 5 is held with a high holding force. ® As described above, a container filled with a fumigant is, for example, as shown in FIG. 4, a heat-resistant outer tube 17 made of a paper tube or the like is fitted in a container made of a synthetic resin or the like. Use in the state of the outer container 18. In addition, 19 in FIG. 4 is an upper lid of the exterior container 18. Hereinafter, a manufacturing method of the heat generating body holding plate of the present invention will be described with reference to FIG. 5. Fig. 5 shows an example of a method for continuously producing the heating element holding plate of the present invention, that is, an embodiment of the heating element holding plate 8 shown in Fig. 2. The features of the manufacturing method of the present invention will be described below in the order of steps. · (First step) A mounting hole 9 is formed at the center in the width direction of the coil substrate 50, and there are five divided grooves 10 at approximately equal intervals in the peripheral portion thereof. The mounting hole 9 is used as a center to form 5 radially. 1 oval smoke hole 1 2. Moreover, in this embodiment, in order to improve the feeding accuracy of the coil substrate 50, circular positioning holes 51 are simultaneously formed in the vicinity of both side end portions of the substrate 50. These positioning holes 51 are equipped with a guide pin with a sharpened tip on the upper die in a later step. While the punch slide is lowered, the guide pin is inserted into the positioning hole 51 to determine the 17 312 of the coil. Invention Specification (Supplement) / 92-06 / 92107727 1231177 position, improve feeding accuracy. When the tip of the guide pin is inserted into the positioning hole 51, the coil must be in a free state. At this time, the coil is held in the open state by the clamp of the feeding device. (Second step) The outer part (peripheral part 14) of the heating element holding plate and the peripheral part of the mounting hole separated by the dividing groove 10 are bent into a cone shape to form the supporting sheet 11 in a certain direction. Five protrusions (rigid reinforcing portions 13) are formed radially around the mounting hole 9. (Third step) _ Form the remaining 10 smoke spray holes 12 radially with the mounting hole 9 as the center. It is necessary to ensure that the smoke spray holes of the heating element holding plate have a certain area or more. The plurality of oval smoke spray holes formed in this embodiment are located close to each other. Therefore, if all the smoke holes are to be demolded at one time, the problem of mold durability may be reduced. However, by forming the plurality of smoke injection holes 12 as described above in the form of the first step and the third step, respectively, maintaining a certain distance from each other, the durability of the mold can be improved. (Fourth step) The heating element holding plate located in the outer shape portion (peripheral portion 14) is pulled out from the substrate 50. As a result, the heat generating body holding plate 8 shown in Fig. 2 is obtained. In this way, the manufacturing method according to the present invention, in particular, forming a plurality of smoke spray holes through the first step and the third step, can simplify the mold structure used in each step and improve its durability. At the same time, since in the first step A mounting hole and a part of the smoke spray hole are formed on the substrate. In the second step, a rigid reinforcing portion is formed on the substrate so as to improve the planar rigidity of the substrate. Therefore, the deformation of the substrate can be prevented when the remaining smoke spray holes are formed in the third step. Excellent 18 312 / Invention Specification (Supplement) / 92-06 / 92107727 1231177 Good manufacturing of products that meet the design. And 'in the manufacturing method of the present invention, according to the hole diameter of the heating element holding plate produced, specifically, for example, when the hole diameter of the heating element holding plate is large, the periphery of the mounting hole performed in the second step The bending of the portion may be performed in the third step. Therefore, it is possible to disperse the deformation caused to the substrate and improve the accuracy of the product size. According to the heating element holding plate of the present invention as described above, by forming the curved support sheet which can be elastically enlarged in diameter and separated by a plurality of divided grooves at substantially equal intervals, the periphery of the heating element for ignition can be uniformly supported. The support sheet capable of elastically expanding the aperture can absorb the force generated when mounting the heating element for ignition, and because the ignition heating element can be easily installed in the mounting hole of the heating element holding plate, the elasticity of the supporting sheet can be used to reduce the The ignition heating element is held by a high holding force, so when the ignition head of the ignition heating element is rubbed with a friction plate or the like, the ignition heating element can be effectively prevented from falling out of the mounting hole. In addition, since there are a plurality of protrusions around the mounting portion on which the heating element for ignition is mounted on the heating element holding plate, the number of these protruding portions is larger than the number of divided grooves formed in the peripheral portion of the mounting hole of the heating element holding plate. In many cases, the protrusions fit the ignition heating element more firmly into the mounting hole of the heating element holding plate, so that the holding force of the ignition heating element can be improved more effectively. Furthermore, in particular, the plurality of smoke injection holes are formed around the mounting hole, for example, in a radial shape, and when protrusion-shaped rigid reinforcing portions such as ovals and rings are formed around the smoke injection holes, a plurality of smoke injection holes are formed. The planar rigidity of the heating element holding plate reduced by the smoke spray hole can be effectively reinforced by the above-mentioned protrusion 19 312 / Invention Specification (Supplement) / 92-06 / 92107727 1231177, which makes it possible to reduce the thickness of the heating element holding plate. And can reduce manufacturing costs. According to the manufacturing method of the heating body holding plate of the present invention, since the plurality of smoke spray holes are formed in the first step and the third step, respectively, the mold structure used in each step can be simplified and its durability can be improved. Since the planar rigidity of the substrate is enhanced by the rigid reinforcing portion formed in the second step on the substrate in which the mounting hole and a part of the smoke injection hole are formed in the first step, it is possible to prevent the remaining smoke injection holes from being formed in the third step Deformation of the substrate. In this way, it is possible to continuously manufacture a product conforming to the design in a small number of steps with good efficiency.
