Description of the Invention: [Technical Field] The present invention relates to a shrink film which can be used for shrink packaging, such as a liquid medicine container such as an eye drop container. BACKGROUND ART Conventionally, as a shrink film for a liquid storage container such as an eye drop container which is formed by shrinking a package and a lid portion which is screwed to the main body portion, it is required to have the visibility of unsealing and unopening, and currently The shrink film disclosed is composed of a region covering the lower surface of the body portion and covering the upper surface of the cover portion, and is provided with a slit portion formed by the cut portion and the non-cut portion extending along the boundary between the upper field and the lower field. a wire; a grip portion located at an upper end edge of the upper field; and a bevel hole line formed by the incision portion and the non-cut portion of the upper field extending obliquely from the grip portion to the transverse hole line (refer to the patent) Document 1). [Patent Document 1] Japanese Laid-Open Patent Publication No. 2001-130621 (Draft No. 2001-130621) SUMMARY OF THE INVENTION Problems to be Solved by the Invention However, in the shrink film disclosed in the above publication, when the lid portion is rotated, the tearing force thereof is used. The relationship between the direction of action and the direction in which the respective slit lines are formed is stronger than the tearing force with respect to the oblique hole line, and therefore the force applied when the cover is rotated Differently, there is a case where the oblique seam hole line is not torn at all and only the transverse seam hole line is torn off. At this time, the cover portion is restored to the original shape, and the opening seal trace cannot be easily visually recognized. Therefore, even if someone exercises such a bad In the case of mischief, it is also easy to visually recognize the unsealed and unopened shrink film. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a film which can surely form a liquid storage container when it is opened, and which can easily recognize a shrink film which is unsealed and unopened. Means for Solving the Problem The shrink film of claim 1 is for packaging a container composed of a body portion and a lid portion coupled to the body portion, and covering the field below the body portion and covering the top portion of the body portion Domain builder. It is characterized by comprising a transverse seam line, a beveled hole line, a transverse slit line incision, and a <shaped incision line. Wherein the transverse slit line extends along the boundary between the upper field and the lower field and surrounds the container, and is composed of a cut portion and a non-cut portion. The oblique slit line is formed in the above-mentioned upper field, and is inclined obliquely downward to the transverse slit line with respect to the unsealing direction of the lid portion, and is composed of a cut portion and a non-cut portion. The transverse slit line incision portion is formed in a triangular region in which the transverse seam line is close to the oblique slit line. Further, the <-shaped incision line is formed by a slanting incision portion formed by the transverse slit line incision portion as a starting point to the oblique line. That is, the shrink film of the first application of the patent range is in the three-shaped narrow region in which the transverse slit line is close to the oblique hole line, and the above-mentioned <-shaped slit line I is provided on the transverse slit line. Herein, the upper field and the lower field boundary in the present invention are not limited to the position corresponding to the lower end of the lid portion when covering the container with the shrink mold, but may also correspond to a position slightly above or below the lower end of the lid portion. For example, it may be located slightly lower than the lower end of the cover portion and corresponding to the shoulder of the body portion. In the shrink film of the second aspect of the patent application, in addition to the above structure, the bending angle of the oblique cut portion is 95 to 150 degrees with respect to the cut portion constituting the transverse slit line of the <-shaped cut line. The shrink film of claim 3, in addition to the foregoing structure, is provided with a horizontal grip on the left or right side of the film, and the lower side end of the cross grip is substantially the same as the transverse hole line. The height and the grip portion of the system are extended on the lower side of the transverse hole line. In the shrink film of the fourth aspect of the patent application, in addition to the foregoing structure, the transverse slit line has a substantially parallel outer circumferential hole line and a lower side transverse hole line, and is surrounded by each transverse hole line. An oblique slit line is formed in the strip-shaped region, and the upper side and the lower side end portion of the grip portion are located at the same height as the respective cross-hooks. Further, the lower side & stitch line is formed as a boundary between the upper field and the lower field, and a portion of the other field is formed by the lower side transverse hole line and the upper side transverse hole line. field. In the case of the shrink film of the fifth item of the Japanese patent, the number of the non-cut portions of the upper side transverse slit line is small in addition to the above-described configuration. The shrink film of the sixth paragraph of the patent patent circumference, in addition to the foregoing structure, is attached to the side gripping portion and starting from the lower end portion of the upper grip portion; A longitudinal slit line formed by the incision portion and the non-cut portion. The shrink film of the seventh item, in addition to the above structure, is provided at an upper portion of the strip-shaped top field and near the upper side transverse slit line, and is provided with an inclined cut portion inclined with respect to the upper side transverse slit line. The shrink film of the eighth aspect of the patent application, in addition to the foregoing structure, is located at the lower portion of the upper field and near the upper transverse hole line, and is provided with an inclined cut portion 'and/or inclined with respect to the upper side & Or at an upper portion of the lower field and near the lower k-hole line, an inclined cut portion inclined with respect to the lower side transverse hole line is provided. A container having a shrink film attached to a ninth application of the patent application is a package which is formed by a shrink film formed by the above structure and which is attached to a container formed by a main body portion and a lid portion connected to the main body portion. According to the shrink film of the first paragraph of the patent scope of the invention, once the rotating cover portion is rotated, the tearing force of the opening is generated along the transverse hole line and the oblique hole line, and the shape of the triangle is cut and the line is borrowed. The inclined incision portion constituting the <shaped incision line can reduce the tearing force with respect to the transverse slit line, and the other side can also exert a certain effect on the oblique slit line. Therefore, the oblique hole line is surely It is torn and becomes a tear piece in the tearing state of the aforementioned triangular field and floats relative to the container. By this, even if someone slaps the cover open, the cover is returned to the original state, and the buyer can also tear the piece as described above. As the mark, it is easy to visually recognize whether or not the lid is opened, and the so-called tampering behavior is effectively prevented. According to the shrink film of the second item of the Shen Sing patent range, the bending angle range of the oblique cut portion is: 95 to 15 G degrees with respect to the incision portion constituting the transverse slit line of the incision line. Therefore, the transverse slit is respectively The tearing force of the hole line and the oblique hole line acts in a balanced manner, so that in the aforementioned triangular field, the oblique hole is surely broken, and the tear piece is surely formed in the Sanshaw area. . . According to the shrinking medium of the third application of the patent application, heat shrinkage is performed in a state where the shrink film is wound around the container to shrink the shrink film in the upper side of the side of the horizontal hole of the package, because the grip portion of the horizontal grip portion is The system is located on the lower side of the transverse slit line, so that the aforementioned grip portion body does not wrinkle, and therefore, the horizontal grip portion can be easily gripped when the shrink film is opened. X, the lower side end portion of the horizontal grip portion is located at substantially the same height as the transverse slit hole line, and therefore, the tearing force with respect to the transverse slit hole line is smoothed by pulling the horizontal grip portion to the horizontal or oblique upper side. The ground is transferred to the horizontal seam line, and the upper surface can be opened under the condition that the shrink film retains the lower field. According to the shrink film of the fourth application patent scope, when the horizontal grip portion is pulled, only the upper side transverse seam hole line can be used. And the strip-shaped field enclosed by the lower side transverse hole line is opened and removed, so that the upper and lower fields of the shrinkage enthalpy can be retained together. According to the shrink film of the fifth paragraph of the patent application, when the shrink film is to be opened by rotating the container cover portion, the same tearing force is exerted on the upper side transverse hole line and the lower side transverse hole line, and the non-cutting portion is small at this time. The lower side seam line will be preferentially torn, so that the aforementioned triangular tear piece is surely formed. That is, even if a person mischievously pranks and opens the lid portion of the container, the purchaser can easily recognize the open and unopened state of the lid portion by visually confirming whether or not the triangular tear-off piece formed after the film is torn. According to the shrink film of claim 6 of the patent application, when the upper field other than the strip-shaped field is not required, the upper grip portion can be gripped and pulled, and the retaining belt is only in the form of 1335294 and the lower field. The above-mentioned upper field was opened and taken off. According to the shrink film of the seventh paragraph of the patent application, when the grip portion is gripped and opened, even if the tearing force from the upper side of the transverse slit line acts downward and tearing occurs in the strip-shaped field, The downward tearing force of the lower inclined cut portion is weakened, and the tearing force is corrected to the lateral direction. Therefore, the opening of the shrink film can be effectively prevented from spreading to the lower field. According to the shrink film of claim 8 of the patent application, when the horizontal gripping portion is used to open the strip-shaped field, the transverse tearing force along the upper transverse hole line and/or the lower transverse hole line can be effectively effective. The ground action, therefore, can reliably retain the area above and below the shrink film. According to the container with a shrink film attached to item 9 of the patent application, a container having the above various opening effects can be provided. I: Embodiment 3 BEST MODE FOR CARRYING OUT THE INVENTION 15 The shrink film of the present invention is used for shrink-wrapping a container comprising a main body portion and a lid portion connected to the main body portion. The container is preliminarily stored with a chemical solution such as eye drops, ear drops, or acupuncture drugs, and the body portion and the lid portion are screwed together, and is suitable for rotating the cover portion when the chemical liquid is used. .

The tearing force is changed from the constituent portion 32 to the oblique cut portion 52, and a cut line of the cut line 51 is opened by the adjacent face. Partial transmission 11 1335294 to other <glyphic incision lines 5 adjacent to the right side thereof. Therefore, while forming the corrugated section, the portion forming the <shaped incision line is also torn, and then the quilting hole line 31 will be The cut portion 32 and the non-cut portion are cut along the right side. After the tearing is completed, the triangular region is torn off and slightly floats relative to the container 5 11 (refer to Fig. 4). % τ, at the barhole line 31 and the oblique slit line 41 are close to each other. 10 15 20 The angular narrow region has a feature of forming a <-shaped incision line 51 at a position substantially the same as the transverse slit line 31, when the lid of the rotating container u is The resulting tearing force reaches the <glyphation incision line 51, and the direction of action of the tearing force changes from the direction of the incision portion 32 (i.e., the right direction) to the direction of the oblique incision portion 52 (i.e., right obliquely upward). The tearing force is reduced with respect to the transverse slit line 31, On the other hand, the tearing force of the oblique seam line 41 is also constant-fixed. Because of the usual 'the aforementioned triangular-shaped tearing piece H-and the initial rotation of the rotating cover': the shape is not formed _ and the 'pre-rhythm (four) η It has a waveform tear at the bottom == 'Even if someone has a bad force, the lid 13 is opened and the lid portion 13 = ΓΓ η η is easily visually recognized as a mark: and the so-called tampering behavior is effectively prevented. The shape J1 forms a glyph incision line 51 in the U-th image, and the number of the 'character' 'two 1' can be appropriately changed according to the size of the container U and the inclination angle of the material constituting the contraction 41. X Relative to (in the first: open (4)", although there is no special balance between the oblique hole line 41 and the transverse hole (4) of the test hole, ^ = 12 1335294 counts but from the above point of view Generally, it is 95 to 150 degrees, and more preferably 100 to 140 degrees. Further, the length of the incision portion 32 and the oblique incision portion 52 constituting the incision line 51 is also the same as the aforementioned bending angle 0, although there is no It is particularly limited to consider the 5 level of the tearing force acting on the oblique slit line 41 and the transverse slit line 31. The design is appropriately designed, but from the foregoing point of view, it is generally preferred that the incision portion 32 is longer than the oblique incision portion 52. Next, other embodiments of the present invention will be sequentially described, and have the same functions and functions as the first embodiment. The same components will be denoted by the same reference numerals and the description of the portions will be omitted as appropriate. Fig. 5 is a front view showing the second embodiment of the shrink film of the present invention. The shrink film B is provided on the right side of the tongue. The point of the lateral grip portion 61 is different from that of the first embodiment, and the lower side end portion -63 of the lateral grip portion 61 is located at substantially the same height as the transverse slit line 31, and the grip portion body 62 is extended. The position on the lower side of the transverse hole line 31. According to the shrink film B' thus formed, the heat shrinkage 15 is applied in a state where the shrink film b is wound around the container to shrink the upper surface 22 of the upper side of the horizontal line 31, because of the grip of the horizontal grip 61 The portion body 62 is located on the lower side of the transverse slit line 31, so that the grip portion body 62 does not wrinkle, and therefore, the lateral grip portion 61 can be easily gripped when the shrink film is opened. Further, the lower side end portion 63 of the lateral grip portion 61 is located at substantially the same height as the horizontal slit line 31, and therefore, by pulling the lateral grip portion 61 to the left direction or the left oblique direction of FIG. The tearing force of the transverse slit line 31 is smoothly transmitted to the transverse slit line 31, and the upper field 22 can be opened and removed in a state where the shrink film Β retains the lower field 21, that is, the state of the aforementioned statutory mark is retained. . Fig. 6 is a front elevational view showing a third embodiment of the shrink film of the present invention. The receiving and fine film C are different from the second embodiment in the point of providing two transverse slit lines. Specifically, the transverse slit has a substantially parallel outer circumferential hole line 34 around the container 11 and The lower side transverse hole line 37 is formed with a beveled hole line 41 in the strip-shaped field 23 surrounded by the transverse slit line 34, 37, and the upper side end portion 64 and the lower side of the lateral grip portion 61 are provided. The end portion 63 is disposed at substantially the same height as each of the five horizontal slit lines 34 and 37. That is, in the third embodiment, the lower side transverse hole line 37 is provided as the boundary between the upper field 22 and the lower field 21, and the lower side transverse hole line 37 and the upper side transverse hole hole are formed in the lower portion of the upper field area 22. An elongated strip-shaped field 23 surrounded by line 34. According to the shrink film C formed by the configuration, pulling the horizontal grip portion 61 to the left or the left obliquely upward in the sixth drawing can open the strip-shaped field 23 only by 10, so that the area above the shrink film c can be shared together. 22 and the next field 21. Therefore, the container or the patient can immediately recognize the container by the front or the inside of the upper field 22 other than the strip field 23, and as long as the so-called identification mark is printed, the identification mark can be shared and printed under The aforementioned statutory label of the field 21, therefore, can prevent the misunderstanding of the container U after the container 15 is opened, and violates the statutory labeling obligation. Further, in Fig. 6, the number of the non-cut portions 39 of the lower lateral slit line 37 is smaller than the non-cut portion 36 of the upper transverse slit line 34. That is, generally, the non-cut portions 39 and 36 are designed to have substantially the same length, and therefore, the length of the cut portion 38 of the lower side transverse hole line 37 is formed longer than the cut portion 35 of the upper side slit line 34, thereby making 20 With the above configuration, when the lid portion 13 of the container 11 is rotated and the shrink film C is opened, the same tearing force acts on the upper side slit line 34 and the lower side slit line 37. The lower transverse seam line 37 with fewer incisions will be preferentially torn 'so as' to form the triangular tear tabs described above. That is, even if someone spoils the cover portion 13 of the container U in a bad manner, the purchaser 14 can visually confirm the presence or absence of the triangular tear piece formed after the film is torn, and the presence or absence of opening of the cover can be easily recognized. Fig. 7 is a front elevational view showing a fourth embodiment of the shrink film of the present invention. The shrink film D is different from the third embodiment in that a convex portion 5 above the grip portion 71 is disposed above the film d, and two strips are formed with the lower end portion of the upper grip portion 71 as a starting point and above the film D. A longitudinal slit line 72 formed by the incision portion and the non-cut portion in the field 2 2 . According to the shrink film D thus formed, if the aforementioned identification mark printed on the upper field 22 other than the strip-shaped field 23 is not required, the upper grip portion 71 is gripped along the longitudinal slit line 72, 72, and then to the seventh Pulling in the right direction in the figure, only the aforementioned identification mark can be unsealed in the state in which the strip-shaped field 23 and the lower field 21 are retained. Fig. 8 is a front elevational view showing a fifth embodiment of the shrink film of the present invention. The contraction film 相 is different from the fourth embodiment in the upper portion of the strip-shaped field 23 and is adjacent to the upper side transverse hole line 34, and a plurality of inclined oblique cut portions 81 are formed in parallel with respect to the upper side transverse slit line 34, respectively. . According to the shrink film formed by the configuration, when the upper grip portion 71 is opened in accordance with the method described in the foregoing fourth embodiment, when the tearing force acts on the upper side of the transverse slit line from below, and in the strip field When the upper portion is torn, the tearing action in the downward direction is also weakened and the tearing force is corrected to the lateral bamboo, m, and the door acts so as to be close to the inclined incision 81 just below the upper transverse hole line. It is possible to effectively prevent the tearing of the shrink film E from spreading to the lower field 21. Figure 9 is a view showing a sixth embodiment of the shrink film of the present invention. The pre-expansion F is different from the fourth embodiment in the upper 7-member field 22 outside the strip-shaped field 23 and close to the upper side seam. At the hole line, a plurality of inclined oblique cut portions 82 are formed in parallel with respect to the upper side slit 15 1335294 hole line 34, respectively, and are at the upper portion of the lower field 21 and near the lower side transverse slit line 37, transverse to the lower side. The slit line 37 is respectively provided in parallel with a plurality of inclined oblique cut portions 83, and according to the shrink film F formed in this manner, when the horizontal grip portion "opens the strip-shaped field 23" is gripped, the upper side is effectively generated. The transverse tearing force of the transverse seam hole material and the lower side transverse seam line 37, therefore, the field 22 and the lower field 21 above the shrink film F can be surely retained. The above is a detailed description of the present invention, and the present invention is not The size and shape of the shrink film itself, and the size, shape, structure, and position of the various components of the machine can be appropriately changed without departing from the gist of the present invention. For example, as disclosed in the foregoing figures. The incision line 51 is formed, and the inclined incision portion 52 constituting the <-shaped incision line 51 is formed from the distal end of the incision portion 32 toward the oblique slit line 41. However, the obliquely-cut line 41 may be divergently formed from the middle of the incision portion 32. Further, regarding the length of the cut portion and the non-cut portion of the various slit lines 31, 41, 34, 37, 72, the positions of the various transverse slit lines 31, 34, 37, the strip-shaped field 23 The width and the inclination angle of the oblique hole line 41 can be appropriately changed in accordance with the size, shape, material, and the like of the shrink-retaining container 11. Further, the shape of the horizontal grip portion or the upper grip portion 71 can be adjusted. Appropriately changed, 20 \ 'In order to facilitate the opening, the arrow indicating the opening direction can also be printed. Furthermore, the inclined incisions 82, 83 in Fig. 9 are not necessarily all set, and are in the shrink film. In design, it can also be set only on the side that preferentially produces the transverse tearing force effect.
