Box main body 12 has case antetheca 121, rear wall 122, diapire 124 and opposed two case end walls 123 and is opened 15 by what the top of case antetheca 121, rear wall 122 and opposed two case end walls 123 surrounded.And then box main body 12 possesses the secondary antetheca 125 that is connected on case antetheca top 17 and roughly extends along case antetheca 121 downwards in box main body inside, prevent the bond layer 14 (with reference to Fig. 3) that the packaging film 36 that is drawn out returns on the volume 30 and make packaging film and cut off the fin 50 that edge 361 leaves from case antetheca 121.As shown in Figure 5, lid 20 possesses two corresponding lid end walls 25.In addition, case antetheca 121 possesses the Fixed Division 136 that can be fixed on case end wall 123.
Fig. 4 represents to hold container 10 and pinch with the right hand 62 state that packaging film 36 is pulled out with left hand 61.Fin 50 is configured on the position of the bisector that comprises the distance between opposed two case end walls 123.Therefore, close to the size (width) of the packaging film between user's case end wall 123 and fin 50 (packaging film grip position) and from the user away from case end wall 123 and the packaging film size between fin about equally.If fin 50 is configured on the position of bisector of the distance that comprises 123 of opposed two case end walls, in the situation that make hand opposite with Fig. 4, namely in the situation that hold container 10 and pinch packaging film 36 with left hand 61 with the right hand 62 and pull out, close to the size (width) of user's case end wall 123 and the packaging film between fin 50 (fetch bit of pinching of packaging film is put) and from the user away from case end wall 123 and the size of the packaging film between fin 50 also about equally, so such use difficult problem can not occur in the past.
Fig. 6 means the general view of the fin 50 of packing film device of the present invention, and Fig. 7 is the approximate three-dimensional map of the fin 50 of Fig. 6.Be used for making packaging film 36 and cut off the fin 50 that leaves from case antetheca 121 at edge 361 as Figure 6 and Figure 7, the part of case antetheca 121 being formed cutting with the mode of the connecting part 55 of secondary antetheca 125 to stay.The lower edge 51 of fin 50 leaves from case antetheca 121 under the effect of the elastic force that is produced by connecting part 55.Fin 50 is configured to, and comprises the bisector 2 of the distance between opposed two case end walls 123.In addition, in the shape of fin 50, lower edge 51 can be linearity or curve-like.Particularly, the shape of fin 50 can be also rectangle (square, oblong) or take fin connecting part 55 and lower edge 51 as upper base or go to the bottom trapezoidal.And then the central portion of lower edge 51 also can be spill 52.Spill 52 can be made the V font as shown in Figure 6.And spill 52 can be made the U font as shown in Figure 10.In the case, the packaging film that is positioned on spill 52 falls into slightly from finned surface, thereby produces the effect of " blade is wiped and touched " at the top 221 of the V font alleviate cutting blade.In addition, pinching when getting film, because be spill, so have the effect that film is easily pinched.Recess 52 can have the otch of U font or V font.In Fig. 6 and Figure 10, the ratio W/H of the maximum height H of the length W of the connecting part of fin 50 and fin (upperlimit between fin connecting part 55 and fin lower edge 51) is 0.5~1.0, is preferably 1~6, more preferably 2~5.In the situation that the length W of fin connecting part is that the maximum height H of fin is namely perpendicular to more than 2 times of the size on the direction of connecting part, larger to the elastic force that fin applies by connecting part, the lower edge that can prevent fin is attached on case antetheca 121 or the undesirable condition such as can not leaves fully and occurs.
Be fastened on packaging film part in spill 52 close to case antetheca 121, the problem of damaging so can avoid being pressed by the top 221 of the V font cutting blade 22 that rotates in its outside.Prevent that the packaging film 36 that is drawn out is configured on the outside face of fin 50 to rolling up the bond layer 14 that returns on 30.Leaving from case antetheca 121 outside faces below of the outside face of fin 50, be in the position of easy contact on the cut-out edge of packaging film 36, so the bond layer on the outside face of fin 50 can be bonding and keep reliably with the cut-out edge of the packaging film 36 that is drawn out.
As shown in Fig. 1, Fig. 2 A and Fig. 2 B, packing film device 1 has the blade tip that covers cutting blade 22 and strippingly is fixed in sealing wall 23 on case antetheca 121.Sealing wall 23 is formed by the extension of lid antetheca 24, and the connecting portion 241 by easy fracture is connected to and covers on antetheca 24.Connecting portion 241 forms from blade tip 223 and leaves both V fonts of sizing, so that the blade tip 223 of cutting blade 22 exposes when sealing wall 23 is peeled off from case antetheca 121.In addition, as shown in Fig. 2 A and Fig. 2 B, sealing wall 23 is bonded on case antetheca 121 by a plurality of adhesive portion 132,134.A plurality of adhesive portion are rounded respectively, in adjacent circular, in the heart distance equates, and can make the area that is near the adhesive portion 134 of the position at the top 221 of the V font of cutting blade 22, less than the area that is in away from the adhesive portion 132 of the position at top 221.
Fig. 8 is after lid 20 moves to the release position a little, comprise the general profile chart of bisector 2 of the packing film device of Fig. 2 A.As shown in Figure 8, if lid 20 to the direction that the opening 15 of box main body 12 is opened around rear wall top 16 anglec of rotation R, the vertical direction size S of the top 242 of the top 221 distance lid antethecas 24 of the V font of cutting blade 22 is larger, and the distance of leaving from the packaging film 36 that is drawn out is larger.By making size S larger, " blade is wiped and touched " phenomenon that the packaging film 36 that is drawn out was pressed and cut off at the top 221 of the V font of cutting blade 22 has the trend of minimizing.
But if in order to reduce " blade wipe touch " and increased in size S, near the vertical dimension T the line 2 of the sealing wall 23 shown in Fig. 2 B diminish.Sealing wall 23 need to stash blade tip 223, do not break again simultaneously from case antetheca 121 sur-face peelings, in addition, before packing film device uses, require to be bonded in reliably case antetheca 121 surfaces upper, the blade tip 223 of cutting blade is covered.Therefore, near the vertical dimension T the bisector 2 of sealing wall 23 need to be for more than certain value, more than for example 10mm.In the present invention, as shown in Figure 2, can make the adhesive portion 134 that is near the position at the top 221 of the V font of cutting blade 22,134 Area Ratio be in the area of adhesive portion 132 of the position far away apart from top 221 little.
In Fig. 8, the condition that " blade wipe touch " do not occur is, on above-below direction during position consistency, fin 50 is not pressed at top 221 when the top 221 of the V of cutting blade 22 font and fin lower edge 51.in addition, in packing film device of the present invention, if establish the width of upper wall 21, be to be of a size of A between rear wall top 16 and lid antetheca top 242, upper wall 21 is R from the angle of rotation of horizontal direction rotation, be of a size of S from lid antetheca top 242 to the top 221 of blade tip, the width of opening 15, be to be of a size of B between rear wall top 16 and fin connecting part 55, upperlimit between fin connecting part 55 and fin lower edge 51 is H, fin 50 is X from the angle of rotation of vertical direction rotation, as angle of rotation R, when X takes off respectively certain value in the scope of formula (1) and (2),
0<R<45°......(1)
0<X<45°......(2)
Select size A, B, S, H, so that satisfy in the whole zone of fin lower edge
S×cosR=A×sinR+H×cosX......(3)
H×sinX≤(A?×cosR+S×sinR)-B......(4)。
As an example, in the time of X=4 °, the angle that the top 221 of the V font of cutting blade and the upperlimit of fin lower edge partly contact is R=9 ° when A=43mm, B=43mm, S=27mm, H=20mm.At this moment, according to calculating formula as can be known, H * sinX=3.10mm, (A * cosR+S * sinR)-B=3.70mm satisfies the relation of following formula.Thus, can prevent above-mentioned " blade is wiped and touched " of packing film device.
Above-mentioned formula (4) comprises H * sinX=(situation of A * cosR+S * sinR)-B...... (4b), but in the case, the blade tip 223 of cutting blade just contact on the fin lower edge and do not press packaging film, so soft packaging film can not be cut off (damage).That is, can not cause in fact " blade is wiped and touched ".In packing film device of the present invention, the fin preferred disposition is to comprise the bisector of the distance between opposed two case end walls.Therefore, close to the size (width) of the packaging film between user's case end wall and fin (packaging film grip position) and from the user away from the case end wall and the packaging film size between fin about equally.Therefore, eliminated in the situation that fin is set from the position that above-mentioned bisector is left, to right hand people or the inconvenience that produces of left hand people's smoothly a certain class people smoothly, can provide concerning the right hand smoothly the people and left hand people both sides smoothly easy-to-use packing film devices all.
In packing film device of the present invention, the lower edge of fin has concave shaped portion.By taking such structure, can not provide to occur " blade is wiped and touched ", being that packaging film is pressed near the top of V font cutting blade and made the packing film device of the cut undesirable condition of packaging film.In packing film device of the present invention, prevent that the packaging film that is drawn out is configured on the outside face of fin 50 to rolling up the bond layer that returns.The following outside face from the case antetheca of the outside face of fin leaves, be on the position at easy contact packing film and cut-out edge (ora terminalis) thereof, so the bond layer on the outside face of fin is brought into play the effect of the ora terminalis of bonding packaging film with keeping being drawn out more reliably.
Fig. 9 is the variation of the packing film device of Fig. 3, means that the lid of packing film device is in the approximate three-dimensional map of the state of release position.In the packing film device of Fig. 9, fin 50 is configured on the position of the bisector that does not comprise two distances between the case end wall.In Fig. 9, be used for preventing being configured on the outside face of fin 50 to volume 30 bond layers that return 14 from the end of rolling up 30 packaging films of pulling out 36, also be configured on case antetheca 121.
In packing film device of the present invention, the sealing wall is formed by the extension of lid antetheca and the connecting portion by easy fracture is connected to and covers on antetheca.Connecting portion has from the blade tip of cutting blade and leaves both V fonts of sizing, so that the blade tip of cutting blade exposes when the sealing wall is peeled off from the case antetheca.The sealing wall is bonded on the case antetheca by a plurality of adhesive portion, is in Area Ratio near the adhesive portion of the position at the top of the V font of cutting blade and is in away from the area of the adhesive portion of the position at top little.Therefore, the sealing wall energy is enough hides blade tip, and can be peeled off from the case front wall surfaces with not rupturing, in addition, has advantages of before packing film device uses to be bonded in reliably the blade tip that covers cutting blade on the case front wall surfaces.
In the present invention, be spill near the central portion of the lower edge of fin, the length W of the connecting part of fin and the ratio W/H of the maximum height H of fin are (Fig. 6, Figure 10) more than 2.Namely, the size W of the connecting part of fin is the maximum height H of fin, namely perpendicular to more than 2 times of the size on the direction of connecting part, thereby larger to the elastic force that fin applies by connecting part, can prevent that the lower edge of fin is attached on case antetheca 121 or the undesirable condition that can not leave fully.In addition, the packaging film part that is fastened on the concave portions of fin is located close to the case antetheca, and press and the problem damaged at the top of having avoided being subjected to the V font cutting blade that rotates in its outside.
In the embodiment of Fig. 3 of the present invention, Fig. 5, Fig. 6, on the bisector that is centered close to the distance between opposed case end wall 123,123 of the spill of the top 221 of the V font of cutting blade 22 and the lower edge 51 of fin, thus, the top 221 of V font is left from the lower edge 51 of fin, thus, the packaging film on the lower edge 51 of fin can not pressed in the top 221 of cutting blade.But, being centered close on the straight line parallel with bisector 22 ' (Figure 10) of the spill of the top 221 of the V font by making cutting blade 22 and the lower edge 51 of fin, rather than be positioned on bisector 2, also can make the top 221 of cutting blade can not press packaging film on the lower edge 51 of fin.
