More specifically, the present invention provides a packaging film device which can prevent the "cutting" phenomenon of the packaging film from being damaged by the pressing of the dicing blade after the container is pulled out. Further, the present invention provides a packaging film device which is improved inconvenience in use for both left-handed and right-handed members. Further, the packaging film device of the present invention is provided with a flap which allows the packaging film and its end edge (cutting edge) to leave the wall surface of the container, and grasps the edge of the packaging film with fingers and pulls the packaging film out of the container. outer. Further, the present invention relates to a packaging film device which can prevent the end edge of the drawn packaging film from being wound up on the roll. [Prior Art] A conventional packaging film device stores a roll of a packaging film for packaging a food or the like in a container, and when the packaging film is used, a predetermined amount of the packaging film is taken out of the container and used for The cutter of the container is cut and used. The film container for packaging disclosed in Patent Document 1 includes a container body 11 for accommodating a roll-shaped packaging film, and a container lid portion 1 2 which is connected to the top edge of the rear portion of the container body so as to be rotatable. The film container for packaging of Patent Document 1 is provided with a protruding sheet 15 and a peelable adhesive 19 ° in the front wall portion of the container. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2005-178901 No. 200502391 In the packaging film device, the roll of the packaging film is housed in the container. When the packaging film is used, the packaging film of a predetermined length is taken out of the container and cut by a cutting blade provided in the container. When the wrapping film roll is pulled out of the container, the packaging film pulled out from the container is pressed by the dicing blade, and the so-called "cutting" problem of injuring the drawn packaging film occurs. That is, the occurrence of "cutting" causes the packaging film to be cut off, and the portion of the packaging film which is pulled out from the container is wound back. Accordingly, a first object of the present invention is to provide a packaging film device which can avoid "cutting". In the conventional packaging film device, if the packaging film and the cutting edge thereof are attached to the outer wall of the container, it is difficult to grasp the cutting edge of the packaging film by hand. To solve this problem, the sealing film is provided with a cutting edge. A portion of the tab that leaves the outer wall of the container. However, its construction is not suitable for both right-handed and left-handed. That is, the conventional tab is applied to the right scorpion and the tab is disposed at a position farther from the user than the center of the long side of the container, when the container is held with the left hand and the package is grasped with the usual right hand. When the film is pulled out, the wide portion of the packaging film to be pulled out is located between the gripping portion and the user. This configuration method becomes a position closer to the user in terms of the left-handed child, and it is difficult to use. Accordingly, another object of the present invention is to provide a packaging film device which has improved tabs which can solve the inconvenience of the aforementioned left-hander and which does not cause difficulty in the use of the right-handed. Another object of the present invention is to provide a packaging film device in which an adhesive is disposed outside the tab in order to prevent the end edge of the drawn packaging film from being wound onto the roll. Other objects and advantages of the present invention will be apparent from the description of the appended claims. The packaging film device of the present invention accommodates a package film roll in a container and can pull the package film out of the container. The container contains a box body and a lid. The box system has: a front wall, a rear wall, a bottom wall, two opposite end walls of the box, and an opening surrounded by the front wall of the box, the rear wall and the opposite end walls of the two boxes; Attached to the upper side of the front wall of the box, the sub-front wall of the box body extending substantially along the front wall of the box, the adhesive layer for preventing the wrapping film from being pulled back onto the roll, and for packaging The film and its cutting edge are separated from the tabs of the front wall of the box. The cover system comprises: an upper wall, a front wall of the cover, and a cutting knife fixed to the front wall of the cover; the upper wall is coupled to the upper side of the rear wall; the blade of the cutting blade is disposed adjacent to the front wall of the box when the cover is closed outside. The shape of the blade of the cutting blade may be linear, but it is preferable to form a V-shape having a top portion that protrudes downward. In the packaging film device of the present invention, the tab is formed by cutting a part of the front wall of the box so as to retain the connection portion with the sub front wall, and the convex force generated by the connection portion between the tab and the sub front wall is convex. The lower edge of the sheet can be rotated relative to the front wall of the box, and the tab is arranged to include a bisector of the distance between the opposite end walls of the two boxes, whereby one product can correspond to both the right and left sides. . Further, by moving the tabs from one or the other at a position including the bisector of the distance between the end walls of the box, it is possible to constitute products suitable for the right and left scorpions. In the present invention, "front" represents the side close to the cutting blade with respect to the roll accommodated in the case body, and "back" represents the opposite side of the phase -6 - 200902391. Further, "upper" represents the side closer to the opening with respect to the roll accommodated in the body of the case.

The tab 50 is disposed at the position of the 2-9-200902391 bisector which includes the distance between the two opposing box end walls 1 2 3 . The box body 12 is provided with a box front wall 121, a rear wall 122, a bottom wall 124, two opposite box end walls 123, and a box front wall 121, a rear wall 122 and two opposite box end walls 23 The opening 15 surrounded by the upper side. The box body 12 further includes: a sub-front wall 17 connected to the front wall of the box front wall, and a sub-front wall 125 extending downwardly along the front wall 1 2 1 of the box body for preventing the wrapping film 36 from being pulled back after being pulled out. The adhesive layer 14 on the object 30 (see Fig. 3), and the tabs 50 for leaving the packaging film and its cutting edge 361 away from the front wall 121 of the box. As shown in Fig. 5, the cover 20 is provided with two corresponding cover end walls 25. The front wall 121' of the tank is provided with a fixing portion 136 that can be fixed to the tank end wall 123. The lid body 20 includes an upper wall 21, a lid front wall 24, and a cutter blade 22 fixed to the front wall of the lid. The upper wall 2 1 is coupled to the upper side 16 of the rear wall. The cutter 22, when the cover 20 closes the opening 15 of the case body, is disposed adjacent to the lower outer side of the front wall 121 of the case, and is formed in a V shape having a top portion 221 which protrudes downward. The top 2 2 of the V-shape of the cutter is located in the vicinity of the bisector 2 of the distance between the two opposite end walls 2 5 and 25. Fig. 4 shows a state in which the container 10 is taken with the left hand 61 and the packaging film 36 is taken by the right hand 62 to pull it out. The tab 50 is disposed at a position including a bisector of a distance between two opposite end walls 12 3 of the opposing ones. Therefore, the size (width) of the packaging film between the end wall 123 of the user and the tab 50 (the gripping position of the packaging film) is close to the packaging film between the end wall 123 of the user and the tab 50 away from the user. The dimensions are roughly equal. In the case where the tab 50 is disposed at a position including the distance of the bisector -10-200902391 of the distance between the two opposing box end walls 133, when the hand is used in the opposite manner to the case of FIG. 4, When the container 10 is held by the right hand 62 and the packaging film 36 is pulled by the left hand 61 to pull it out, the size (width) of the packaging film between the end wall 123 of the user and the tab 50 (the gripping position of the packaging film) is approached. The size of the packaging film between the end wall 1 23 and the tab 50 away from the user is substantially equal, so that the problem of difficulty in conventional use does not occur. Fig. 6 is a schematic plan view showing the tab 50 of the packaging film device of the present invention. Fig. 7 is a schematic perspective view of the tab 50 of Fig. 6. The tab 50 for letting the wrapping film 36 and its cutting edge 361 leave the front wall 121 of the box, as shown in Figures 6 and 7, retaining a portion of the front wall 121 of the box with the sub front wall 1 The connecting portion 55 of the 25 is formed by cutting. The lower edge 5-1 of the tab 50 is separated from the front wall 121 by the elastic force generated by the joint portion 55. The tabs 50 are arranged to include a 2 bisector 2 with respect to the distance between the two end walls 123 of the box. Further, the shape of the fin 50 may be linear or curved in the lower edge 5 1 . Specifically, the shape ' of the tab 50 may be a rectangle (square, rectangle), or a trapezoid having the tab connecting portion 5 5 and the lower edge 51 as an upper or lower bottom. The central portion of the lower edge 51 may form a concave shape 52. The concave shape 52 may be formed in a V shape as shown in Fig. 6, or may be formed in a U shape as shown in Fig. 10. At this time, the packaging film placed on the concave shape 52 is slightly recessed from the convex surface, and the effect of suppressing the "cutting" of the V-shaped top portion 22 1 of the cutting blade is produced. Further, when the film is grasped, it has an effect of easily grasping the film due to the formation of the concave shape. The concave shape 52 may have a U-shaped or V-shaped notch. In Fig. 6 and Fig. 10, the ratio of the length W of the joint portion of the tab 50 to the maximum height 凸 of the tab (the maximum dimension of the tab joint portion 55 and the lower edge of the tab 11 - 200902391) W/ The enthalpy is 0.5 to 1.0, preferably 1 to 6, more preferably 2 to 5. When the length W of the connecting portion of the tab is larger than the maximum height Η of the tab, that is, the dimension H in the direction perpendicular to the connecting portion, the connecting portion imparts a large elastic force to the tab, and the convex portion can be prevented from being convex. The lower edge of the sheet is attached to the front wall of the box 1 2 1 or not enough to leave. The portion of the packaging film that is engaged with the concave shape is prevented from being damaged by being pressed against the top portion 22 of the V-shaped cutting blade 22 that is externally rotated due to its position close to the front wall 121 of the box. The adhesive layer 14 for preventing the stretched packaging film 36 from being wound on the roll 30 is disposed on the outer surface of the tab 50. The outer surface of the tab 50 is separated from the outer surface of the front wall 121 of the box and is located at a position where it is easy to contact the cutting edge of the packaging film 36. Therefore, the adhesive layer on the outer surface of the tab 50 can cut off the drawn packaging film 36. The edges do stick and remain. As shown in Fig. 1, Fig. 2, and Fig. 2, the packaging film device 1 includes a sealing wall 2 for covering the blade of the cutting blade 22 and being detachably attached to the front wall 1 1 1 of the case. . The sealing wall 23 is formed by the extension of the front wall 24 of the cover, and is connected to the front wall 24 of the cover by a connecting portion 241 which is easily broken. The connecting portion 241 is formed such that the blade edge 223 of the cutter blade 22 is exposed after being peeled off from the tank front wall 1 21, and is formed in a V shape which is different from the blade edge 223 by a predetermined size. As shown in Fig. 2 and Fig. 2, the sealing wall 23 is adhered to the tank front wall 121 by a plurality of adhesive portions 132, 134. A plurality of adhesive portions each having a circular shape and having the same distance between the centers of adjacent circular circles and approaching the position of the adhesive portion 134 at the position of the V-shaped top portion 221 of the cutting blade 22 can be closer to the position away from the top portion 221 The area of the adhesive portion 132 is -12-200902391 smaller. Fig. 8 is a schematic perspective view of the 2 bisector 2 of the packaging film device of the dad when the cover 20 is slightly moved to the open position. For example: the top 2 21 of the V-shaped shape of the cutting blade 2 2 is shown, if the direction of the opening 15 of the cover body 20 is about the rear side of the rear wall 16 at an angle R when the vertical direction from the upper side 242 of the front wall 24 of the cover The dimension s ' will be a greater distance from the drawn packaging film 36. The "cut" phenomenon in which the top portion 221 of the V-shaped cutting blade 22 is pressed with S and the drawn film 36 is pressed and cut is reduced. However, when the size S is increased in order to reduce the "cut" phenomenon, the vertical dimension T near the line 2 of the sealing wall 2 3 shown in Fig. 2B will change the sealing wall 23' to cover the blade 223 and from 121 without breaking. The surface peeling is applied to the surface of the front wall 121 of the box to cover the cutting edge of the cutting blade before the use of the packaging film device. Therefore, the vertical dimension T near the 2 bisector 2 of the sealing wall 23 is more than 値. , for example, 1 〇mm or more. In the present invention, as shown, the area of 134, 134 located near the top 221 of the V-shape of the cutter 22 can be made smaller than the area of adhesion from the position of the top 221 . In Fig. 8, when the position of the lower edge 5 1 of the V-shaped top portion 221 of the dicing blade 22 coincides in the upper-lower direction, the state of the top portion 2 2 1 without the sheet 50 becomes a condition that "cutting" does not occur. In the present film-issuing device, the width of the upper wall 21, that is, the dimension between the upper side of the front wall 1 and the upper side 242 of the front wall is set to A, and the upper wall 21 is opened and rotated relative to the 2nd, 8th, and 8th. The size of the package is thin, such as the first small. The front wall of the sealed box can be 223 °, and the angle of the cover 132 and the tab pressing the convex part 6 and the angle of the cover in the horizontal-13-200902391 direction should be set to R' to cover the upper edge 242 of the front wall to the blade edge. The size of the opening is set to S, and the width of the opening 15, that is, the size between the upper side of the rear wall 1 and the connecting portion 55 is B'. The maximum size between the tab connecting portions 5 5 and 51 is set to Η, and the tab 5 0 The vertical rotation angle is set to X, and the rotation angles R and X are the equations (1) and (2) 0< R < 45, respectively. ···(1) 0<X<45. ···(2) When the range is ’' In the entire area of the lower edge of the tab, the dimensions A, B, S' Η are:
SxcosR = AxsinR + HxcosX··· (3)SxcosR = AxsinR + HxcosX··· (3)
HxsinX幺（AxcosR+SxsinR)-B··· (4)。 作爲其一例，當X = 4°時，關於切割刀之V 部221與凸片下緣之最大尺寸部分接觸的声 A = 4 3 m m、B = 4 3 m m、S = 2 7 m m、Η = 2 0 m ra 時 R 爲 ，代入計算式 ’ HxsinX = 3.10mm ’ （ΑχHxsinX幺(AxcosR+SxsinR)-B··· (4). As an example, when X = 4°, the sound A of the V portion 221 of the dicing blade in contact with the largest dimension portion of the lower edge of the tab A = 4 3 mm, B = 4 3 mm, S = 2 7 mm, Η = When 2 0 m ra, R is, and substituted into the formula 'HxsinX = 3.10mm ' (Αχ
SinR)-B = 3.70mm，可知是符合上述關係。藉此可 薄膜裝置之前述的「割傷」° 上述式（4)雖包含 HxsinX = (AxcosR + SxsinR) 的情形，這時，切割刀的刀鋒僅接觸凸片下緣’ 頂部22 1 6與凸片 凸片下緣 方向的旋 合以下條 字形的頂 I度，當 9°。這時 c 〇 s R + S X 防止包裝 -B …（4b) 並不會按 14 - 200902391 壓包裝薄膜’因此柔軟的包裝薄膜不會發生切斷（損傷）。 亦即’實質上不會發生「割傷」。本發明之包裝薄膜裝置 中’凸片較佳爲配置成包含相對向的2個箱端壁間的距離 之2等分線。因此’接近使用者之箱端壁和凸片（包裝薄 膜的抓取位置）間之包裝薄膜的尺寸（寬度）、與遠離使用者 之箱端壁和凸片間之包裝薄膜的尺寸大致相等。因此，在 離開前述2等分線的位置設置凸片時對左撇子或右撇子的 任一方產生不便的問題能獲得解決，而提供出一種右撇子 及左撇子雙方都容易使用之包裝薄膜裝置。 本發明之包裝薄膜裝置中，凸片的下緣具有凹形部。 依據此構造，所提供之包裝薄膜裝置，不致發生「割傷」 ，亦即不致因V字形切割刀的頂部附近按壓包裝薄膜而造 成包裝薄膜切斷。本發明之包裝薄膜裝置中，用來防止被 拉出的包裝薄膜捲回捲狀物上之黏著劑層，係配置於凸片 50的外面上。凸片的外面，其下邊離開箱前壁的外面，而 位於包裝薄膜及其切斷緣（端緣）容易接觸的位置。因此， 凸片外面上的黏著劑層，能將被拉出的包裝薄膜的端緣更 確實地黏著並予以保持而發揮優異的效果。 第9圖係第3圖的包裝薄膜裝置的變形例，係顯示包 裝薄膜裝置的蓋體位於打開位置的狀態之槪略立體圖。第 9圖的包裝薄膜裝置中，凸片50配置於不包含2個箱端壁 間的距離的2等分線的位置。第9圖中，用來防止從捲狀 物3 0拉出後的包裝薄膜3 6的端部捲回捲狀物3 0上之黏 著劑層1 4，除配置於凸片5 0的外面上’進一步配置於箱 -15- 200902391 前壁121上。 本發明之包裝薄膜裝置中，密封壁，係利用蓋前壁的 延長部來形成，且藉由容易破裂的連接部來連接於蓋前壁 。爲了在從箱前壁剝離密封壁後使切割刀的刀鋒露出，連 接部係形成與切割刀之刀鋒離既定尺寸之V字形。密封壁 ，係利用複數個黏著部來黏著於箱前壁，且位於切割刀的 V字形頂部附近之黏著部的面積，係比位於遠離頂部的位 置之黏著部的面積更小。因此，密封壁，可覆蓋刀鋒並以 不破裂的方式從箱前壁的表面剝離，又在包裝薄膜裝置之 使用前，能確實黏著於箱前壁的表面，以覆蓋切割刀之刀 鋒。 本發明中，凸片下緣的中央部附近呈凹形，凸片的連 結部的長度W和凸片的最大高度Η之比例W/H爲2以上（ 第6圖、第10圖）。亦即，當凸片之連結部的長度W，相 對於凸片之最大高度Η、亦即與連結部垂直的方向之尺寸 Η ’在2以上的情形，連結部賦予凸片之彈力大，而能防 止凸片下緣附著於箱前壁121或不夠離開。又卡合於凸片 的凹形部分之包裝薄膜部分，由於位在接近箱前壁的位置 ’可避免被在其外部旋動之V字形切割刀的頂部按壓而造 成損傷。 本發明之第3圖、第5圖、第6圖中，切割刀22之 V字形的頂部2 2 1及凸片下緣5 1之凹形中心，係位於相 對向之箱端壁123 ' 123間之距離的2等分線2上，藉此 使V字形的頂部22 1離開凸片下緣5丨，而使切割刀的頂 -16- 200902391 部221不致按壓於凸片下緣51上之包裝薄膜。然而’不 是位在2等分線2上，而是讓切割刀22之V字形的頂部 22 1及凸片下緣5 1之凹形中心位於與2等分線2平行的直 線2’上（第10圖），藉此也能使切割刀的頂部221不致按 壓於凸片下緣51上之包裝薄膜。 【圖式簡單說明】 第1圖係本發明的1實施例之包裝薄膜裝置之使用開 始前的槪略立體圖。 第2A圖係將第1圖的包裝薄膜裝置之密封壁23除去 的狀態之包裝薄膜裝置的槪略立體圖。 第2B圖係從箱前壁121卸下的密封壁23之前視圖。 第3圖係第2A圖的包裝薄膜裝置之蓋體位於打開位 置的狀態之槪略立體圖。 第4圖係顯示，從第3圖的包裝薄膜裝置將包裝薄膜 用手拉出的狀態之槪略立體截面圖。 第5圖係將第2A圖的包裝薄膜裝置之箱前壁及副前 壁展開之槪略立體圖。 第6圖係顯示本發明的包裝薄膜裝置之凸片部分之槪 略俯視圖。 第7圖係第6圖的凸片部分之槪略立體圖。 第8圖係將蓋體稍往打開位置移動時，沿第2 A圖之 包裝薄膜裝置的2等分線2之槪略立體圖。 第9圖係和第3圖同樣的包裝薄膜裝置的蓋體位於打 -17- 200902391 開位置的狀態之槪略立體圖，但凸片配置於不包含2個箱 前壁間的距離之2等分線的位置。 第1 0圖係凸片下緣形成U字形之凸片部分的槪略俯 視圖。 【主要元件符號說明】 1 :包裝薄膜裝置 2 : 2等分線 2 ’ ：凹形的中心線 10 :容器 1 2 :箱本體 1 4 :黏著劑層 15 :開口 1 6 :後壁上邊 17 :箱前壁上邊（彎折部） 20 :蓋體 21 :上壁 22 :切割刀 2 3 :密封壁 24 :蓋前壁 25 :蓋端壁 3 0 :捲狀物 36 :包裝薄膜 50 :凸片 -18- 200902391 5 1 :凸片下緣 5 2 :凹形部 55 :凸片連結部（上邊） 5 7 :半圓形部分 61 :左手 62 :右手 1 2 1 :箱前壁 1 2 2 :後壁 1 2 3 :箱端壁 124 :底壁 1 2 5 :副前壁 1 3 2、1 3 4 :黏著部 1 3 6 :固接部 2 2 1 :頂部 223 :刀鋒 2 4 1 :連接部 242 :蓋前壁上邊 3 6 1 :包裝薄膜端緣 Η :凸片最大尺寸 W:凸片的連結部長度SinR)-B = 3.70mm, which is consistent with the above relationship. Therefore, the above-mentioned "cutting" of the thin film device is possible. In the case where the above formula (4) includes HxsinX = (AxcosR + SxsinR), the blade edge of the cutting blade only contacts the lower edge of the tab 'top 22 16 and the tab The rotation of the lower edge of the tab is the first degree of the following zigzag, when 9°. At this time, c 〇 s R + S X prevents the package -B ...(4b) from pressing the packaging film according to 14 - 200902391', so that the soft packaging film does not cut (damage). That is, 'substantially no "cutting" occurs. In the packaging film device of the present invention, the tabs are preferably arranged to include a bisector of the distance between the opposing two end walls of the box. Therefore, the size (width) of the packaging film between the end wall of the case and the tab (the gripping position of the packaging film) of the user is substantially equal to the size of the packaging film between the end wall of the case and the tab away from the user. Therefore, the problem of inconvenience to either of the left-handed or right-handed members when the tabs are disposed at the position away from the aforementioned two bisectors can be solved, and a packaging film device which is easy to use both the right-handed and the left-handed is provided. In the packaging film device of the present invention, the lower edge of the tab has a concave portion. According to this configuration, the package film device to be provided does not cause "cutting", that is, the packaging film is not cut by pressing the packaging film near the top of the V-shaped cutting blade. In the packaging film device of the present invention, the adhesive layer for preventing the drawn packaging film from being wound up on the roll is disposed on the outer surface of the tab 50. The outer side of the tab has a lower edge away from the outer surface of the front wall of the box, and is located at a position where the packaging film and its cutting edge (end edge) are easily accessible. Therefore, the adhesive layer on the outer surface of the fin can provide an excellent effect by adhering and holding the edge of the drawn packaging film more reliably. Fig. 9 is a perspective view showing a modification of the packaging film device of Fig. 3, showing a state in which the lid of the packaging film device is in an open position. In the packaging film device of Fig. 9, the fins 50 are disposed at positions that do not include the bisector of the distance between the two end walls. In Fig. 9, the adhesive layer 14 for retracting the end of the packaging film 36 after being pulled out from the roll 30 is wound on the outer surface of the tab 50. ' Further configuration on the front wall 121 of the box -15- 200902391. In the packaging film device of the present invention, the sealing wall is formed by the extension of the front wall of the lid, and is connected to the front wall of the lid by a joint portion which is easily broken. In order to expose the blade of the cutting blade after peeling the sealing wall from the front wall of the box, the connecting portion forms a V-shape which is separated from the blade of the cutting blade by a predetermined size. The sealing wall is adhered to the front wall of the box by a plurality of adhesive portions, and the area of the adhesive portion located near the top of the V-shape of the cutting blade is smaller than the area of the adhesive portion located far from the top. Therefore, the sealing wall can cover the blade edge and peel off from the surface of the front wall of the box in a non-ruptured manner, and can be surely adhered to the surface of the front wall of the box before the use of the packaging film device to cover the blade of the cutting blade. In the present invention, the vicinity of the central portion of the lower edge of the fin is concave, and the ratio W/H of the length W of the joined portion of the tab to the maximum height 凸 of the tab is 2 or more (Fig. 6 and Fig. 10). That is, when the length W of the connecting portion of the tab is larger than the maximum height 凸 of the tab, that is, the dimension Η ' in the direction perpendicular to the connecting portion, the connecting portion imparts a large elastic force to the tab, and It can prevent the lower edge of the tab from adhering to the front wall 121 of the box or not enough to leave. The portion of the packaging film which is further engaged with the concave portion of the tab is prevented from being pressed by the top of the V-shaped cutter which is externally swung by the position 'being close to the front wall of the box to cause damage. In the third, fifth, and sixth figures of the present invention, the concave center of the V-shaped top portion 2 1 1 of the cutting blade 22 and the lower edge 5 1 of the tab is located at the opposite end wall 123 ' 123 The distance between the two bisectors 2, whereby the top 22 1 of the V-shape is separated from the lower edge 5 凸 of the tab, so that the top -16 - 200902391 portion 221 of the cutting blade is not pressed against the lower edge 51 of the tab Packaging film. However, 'not on the 2 bisector 2, but the top 22 1 of the V-shape of the cutter 22 and the concave center of the lower edge 51 of the tab are located on a straight line 2' parallel to the 2 bisector 2 ( Fig. 10), whereby the top portion 221 of the cutting blade can be prevented from being pressed against the packaging film on the lower edge 51 of the tab.
