Fig. 6 is the general view of the fin 50 of expression packing film device of the present invention, and Fig. 7 is the approximate three-dimensional map of the fin 50 of Fig. 6.Being used for making packaging film 36 and cutting off the fin 50 that leaves from case antetheca 121 at edge 361 is as Figure 6 and Figure 7 the part of case antetheca 121 to be cut and formed to stay with the mode of the connecting part 55 of secondary antetheca 125.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 also can be rectangle (square, oblong) or with fin connecting part 55 and lower edge 51 be upper base or go to the bottom trapezoidal.And then the central portion of lower edge 51 also can be spill 52.In the case, the packaging film that is positioned on the spill 52 falls into slightly from finned surface, thereby produces the effect of " blade is wiped and bumped " at the top 221 that alleviates the vee shape that cuts off blade.In addition, pinching when getting film, because be spill, so have the effect that film is pinched easily.Recess 52 can have the otch of U font or vee shape.The length W of the connecting part of fin 50 and the ratio W/H of the maximum height H of fin are 0.5～1.0, are preferably 1～6, more preferably 2～5.At the length W of fin connecting part is that the maximum height H of fin is promptly under the situation more than 2 times perpendicular to the size on the direction of connecting part, bigger to the elastic force that fin applies by connecting part, the lower edge that can prevent fin is attached on the case antetheca 121 or undesirable condition such as can not leave fully and take place.
The packaging film that is fastened in the spill 52 partly approaches case antetheca 121, the problem of damaging so can avoid being pushed by the top 221 that the vee shape that rotates in its outside cuts off blade 22.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.The bottom of the outside face of fin 50 is left from case antetheca 121 outside faces, 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 reliably and keep with the cut-out edge of the packaging film 36 that is drawn out.
Shown in Fig. 1, Fig. 2 A and Fig. 2 B, packing film device 1 has the blade tip that cover to cut off blade 22 and strippingly is fixed in sealing wall 23 on the 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 and covers on the antetheca 24.Connecting portion 241 forms from blade tip 223 and leaves both vee shapes of sizing, so that the blade tip 223 that is cut off blade 22 when case antetheca 121 is peeled off at sealing wall 23 exposes.In addition, shown in Fig. 2 A and Fig. 2 B, sealing wall 23 is bonded on the case antetheca 121 by a plurality of adhesive portion 132,134.A plurality of adhesive portion are rounded respectively, in the heart distance equates in the adjacent circular, and can make the area that is near the adhesive portion 134 of the position at the top 221 of the vee shape that cuts off blade 22, littler than the area that is in away from the adhesive portion 132 of the position at top 221.
Fig. 8 be lid 20 a little after move the release position, 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 the rear wall top 16 anglec of rotation R, the vertical direction size S of top 242 of top 221 distance lid antethecas 24 of vee shape that then cuts off blade 22 is big more, and the distance of leaving from the packaging film 36 that is drawn out is big more.By making size S bigger, " blade is wiped and bumped " phenomenon that the packaging film 36 that is drawn out was pushed and cut off at the top 221 of the vee shape of cut-out blade 22 has the trend of minimizing.
But if in order to reduce " blade wipe bump " and increased in size S, then near the vertical dimension T the line 2 of the sealing wall 23 shown in Fig. 2 B diminish.Sealing wall 23 need 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 blade tips 223 coverings that blade was gone up, will be cut off on case antetheca 121 surfaces.Therefore, near the vertical dimension T the bisector 2 of sealing wall 23 need be for more than the certain value, more than for example 10mm.In the present invention, as shown in Figure 2, can make be near the area of the adhesive portion 134,134 of the position at the top 221 of the vee shape that cuts off blade 22 littler than the area of the adhesive portion 132 that is in the position far away apart from top 221.
In Fig. 8, the condition that " blade wipe bump " do not take place is, when the top 221 of the vee shape that cuts off blade 22 and fin lower edge 51 on above-below direction during position consistency, fin 50 (supposition upperlimit H is on the bisector 2) is not pushed at top 221.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 the lid antetheca top 242, upper wall 21 is R from the angle of rotation of horizontal direction rotation, to the top 221 of blade tip, be of a size of S from lid antetheca top 242, the width of opening 15, be to be of a size of B between rear wall top 16 and the kink 55, upperlimit between fin kink 55 and the fin lower edge 51 is H, fin 50 is X from the angle of rotation of vertical direction rotation, then as angle of rotation R, when X takes off certain value in the scope of formula (1) and (2) respectively
0＜R＜45°......(1)
0＜X＜45°......(2)
Select size A, B, S, H, so that in the whole zone of fin lower edge, satisfy
S×cosR＝A×sinR+H×cosX......(3)
H×sinX≤(A×cosR+S×sinR)-B......(4)。
As an example, in the time of X=4 °, cutting off the angle that top 221 and the upperlimit of fin lower edge of the vee shape of blade 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 bumped " 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 that cuts off blade just contact on the fin lower edge and do not push packaging film, so soft packaging film can not be cut off (damage).That is, can not cause " blade is wiped and bumped " in fact.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, approach the packaging film between user's case end wall and the fin (packaging film grip position) size (width) and from the user away from the case end wall and the packaging film size between the fin about equally.Therefore, eliminated under the position of leaving from above-mentioned bisector is provided with the situation of fin, 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 all easy-to-use packing film device.
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 take place " blade is wiped and bumped ", being that packaging film is cut off by vee shape and pushed near the top of blade and make the packing film device of the cut undesirable condition of packaging film.
In packing film device of the present invention, prevent that the bond layer that the packaging film that is drawn out returns is configured on the outside face of fin on volume.The bottom of the outside face of fin is left from the outside face of case antetheca, be on the position at easy contact packing film and cut-out edge (ora terminalis) thereof, so the performance of the bond layer on the outside face of fin is more bonding and the effect of the ora terminalis of the packaging film that maintenance is drawn out.
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 and covers on the antetheca.Connecting portion has from the blade tip that cuts off blade and leaves both vee shapes of sizing, so that the blade tip that is cut off blade at the sealing wall when the case antetheca is peeled off exposes.The sealing wall is bonded on the case antetheca by a plurality of adhesive portion, is near the area of the adhesive portion of the position at the top of the vee shape that cuts off blade littler than the area that is in away from the adhesive portion of the position at top.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 the advantage that can be bonded in the blade tip of covering cut-out blade on the case front wall surfaces before packing film device uses reliably.
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 more than 2.Promptly, the size W of the connecting part of fin is the maximum height H of fin, promptly perpendicular to more than 2 times of the size on the direction of connecting part, thereby bigger to the elastic force that fin applies by connecting part, the lower edge that can prevent fin is attached on the case antetheca 121 or the undesirable condition that can not leave fully.In addition, be fastened on packaging film on the concave portions of fin and partly approach the case antetheca and locate, push and the problem damaged at the top of having avoided being subjected to the vee shape that rotates in its outside to cut off blade.
