Description

1311970 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to an easy-opening seal to cry, and the gemstone-upper surface, which surrounds the plastic baggear, is sealed from the flange. D卩 'It's bad to put the packaging container [previous technology] Tofu packaging is to put the tofu into the plastic sentence dreams in the bag container, the cap is completely inside the 'put _ hemp hand peeling film _ the department, in similar business It. Since it is difficult to handle carelessly, also: When two seals are used, the seal must be cut with a knife. Although the iron capacity,; installed to open = easy to contradict each other, the packaging technology is contained in, for example, take the 8-1〇-面6. The part of the pick is formed on the substrate, so the peeling part is opened with the fingertip. This stripping section provides a starting point for opening. However, even if the Japanese temple, such as If, is provided with a non-adhesive peeling portion, it is difficult to imagine that the film is completely adhered to the opening of the tofu package. Because the tofu packaging container is soft and not hearty. 5, the packaging container with juice pickles (see JP-A-2002-u this * \ concept is 'to cover the switch mouth label, adhere to the surface of the cover, = filling airtight, and the container Easy to open. However, in this case, juice

The switch around the two ports is leaking and the tofu is difficult to remove and deformed because the switch port is much smaller than the container. U Λ 斤, the inventors have developed a sealed container with a broken portion (Just - 驷 # 6~21791) 'First break the flange around the opening of the packaging container The film of the strong seal is peeled off. In this invention: a break groove is formed to facilitate breaking the flange. However, due to the presence of the groove in this structure, the container factory may cause the flange to bend when it is shipped. Furthermore, by 1311970 3 food packaging process or at the time of merchandise display, the flange may bend, = port;;:! When the flange is broken in the groove: = leaking out, in fact, the flange has been reported Bending preparation #忐兀忠拉忐^ . To break the flange, the flange must be bent from the end - (4) another _τ end, which is not yet fully understood. In the case that it is difficult to open the seal, the edge cannot be broken, and all of them have iiir(10). Further, the present invention is directed to the provision of an easy-opening sealed container, a sealed queen, and a quick-opening. To solve the above problem, the structure of the sealed container of the present invention is surrounded by the opening of the plastic packaging container, and the sealing portion includes the following mechanism: two or all of the flanges == joints The edge is divided into the opening portion $= to the inward or outward dog. · When the peeling 臈 is peeled off along the flange, the tearing part of the y part is exposed; drilling on the flange, g peeling the 臈, the sealing film is located at the tearing The flange of the outer side of the crack is in the structure of the container to be sealed, and the sealing film which is sealed by the plastic g-loader is sealed, and is adhered to the periphery. The present invention solves this problem and keeps the seal safe. The upper surface of the flange around the opening portion has a reinforcing function of the peeling film on the lower surface of the flange. Furthermore, in the flange - part or all of, the dry one contains the cutting line and the joint, so the flange is pre-set, the side and the outer side. The knife is separated from the state of formation 1311970. The protrusion = =: = ° the outer part is preventable, and the opening part is "; (3) the side is integrated. , , ', the dog, the inner side of the sputum and the outer part form a separable The inner b structure and method of the state. For example, the flange of the body is cut, i edge; the part rr, and only the inner part = the edge is placed in the structure and method. For example, the flange of the body is cut open = the outer part On the opposite side, the flange can be connected to the connecting edge by the connecting edge ίίΠΤ: the connecting edge of the flange or the dotted line. The L3 knife is broken and the inner side and the outer side can divide the dog's edge into the inner side and the outer side. The opening of the packaging container, such as the polygonal packaging container is set in the i part 2 疋 =. If the tearing line is in the part of the packaging container, if sealed, ίίϊ: completely unobstructed from the packaging container The second part is to open the upper edge of the surface, on the lower surface and the piece. However, the adhesion can be used from the outer side of the ^7-Fu Fantasy, both of which are necessary strips that are easy to toughen. Sealing film : The second is the adhesion that is difficult to peel off, or the i/drilled "the part.

This type of tape forms two edges: surface = off film, which can be straightened by a flange The width of the lower surface is slightly narrower. For the case of a slightly narrower width J, the size is 12x 8 cm, and the flange = cypress

Lu's best tape width is 8 to 8.5 mm, which is wider than the flange. Y is the main point of t. The maximum point 直线 of the straight line i 谬 is used, and 1 is 10_15% of the stamping type, and the cost is low. When a linear tape is used as the release film, a flange tear portion can be formed in the press. Therefore, in addition, the step can be made at a low price. Because of the increase, the loss of a large number of raw items = ϊ:; 'In the case of the face, the first step =: more | side linear film is also difficult to secondary. ^ Double, the glue's first film only succumbed to the first film that was withered, so single-sided glue was used. The second dimension σ and the plane shape of the opening are four sides open. {Eat f shape other packaging capacity ^ ' For example, ίί 为 为 pentagon packaging container, hexagonal housing ^ 装装器' actually has a large _ Food packaging "; filling edge - partial or full circumference: into the lower 1311970 body shape f surface display 'by curved tape, (four) shape or even round shape - outward film operation, with peeling start, peeling In the case of martyrdom, the protruding portion can be formed. If the peeling film is used, it can be located in the packaging container. If the direction is inward == outside = when it is touched, the peeling start part is located at the position where the finger "*2" touches the peeling start portion. Therefore, the consumer will make an organic 3 The question of cheek tm" and this inward peeling start is to give consumption. The beginning of the outward peeling is easy: 髭 = sealing mechanism. The peeling start portion can be colored, and the peeling start can be made = in order to strengthen the film in the inner portion of the tear portion, the packaging container needs to be made of polyethylene terephthalate, ffifc w ethylene, or the same advantages of these materials. In the case where the propylene, poly, and release film are adhered to the packaging container, the protruding sealing film does not 'bend. However, when the release film is peeled off, teared, cracked. I. The beginning of the construction of the packaging container in the present invention is carried out by the manufacturer of the packaging container I at the following: = 1311970. For example, the manufacturer does not 耽 = Slope 7, the winter consumer, all mistakes: Tr production; the fee includes the capacity; the second is the quadrilateral or = has the same advantages of the transmission type [Embodiment] See the specific examples to explain the present invention as follows. In the first example, the reference number is =, the split 19' is taken as: the second is the surrounding flange'. Under the flange 12 with the tearing portion 19, the film & has a strengthening function. , 疋 in the tofu and other products have been stored in the packaging container u s 14, 吏;: Τ 4, ΐ 22% side: " 3 and the outer part 19b 〇 19a ίί inch ' can be arbitrarily determined. However, the joint portion 19b must satisfy the separation between the Κ Κ Κ , 14 until the peeling film i6 Ϊ ΐ ί ί is further torn. In the sealing film 15 and the peeling film 16 === two = state, even for the flanges 4 and 5, the forming of the cutting line 19a and the joint 1% of the packing capacity 1311970 were observed. For example, it can be made of polypropylene, which can be made of polypropylene, and the thickness of the sheet is 44 mm. The machine is made of ς:: It is made by coffee, and the width is visually recognizable. The length of the line is about 25 19b. A length of about 〇1 to 〇3 mm is sufficient. This good connection shows the connection 19b. The above values are only examples of the conditions of the attention of Putian and the size of the packaging container, and can be selected at will. When the sealed container of the first specific example is formed as described above, the tearing portion 19 is cried by the machine. Here, the tear portion 19, the inner side I is connected in the dog's rim 12 shape „ 19b', so that the separation Μ is the inner side of the dead portion 17 and the outer portion 18, and the lion's lion membrane 16 is in Fig. 17). The lower surface of the portion 17 and the outer side of the adhesive edge 12 (the weaker. However, even under the rising temperature of the f-brother, the dry strength of the person is still weak. The money is used inside the dense film 15 Part 13 and the outer part 14 two parts (the upper surface of the H, extending to the dead part of 12, 23 for the intima b and the flange ship (four) _15 need ^ _ί 16 respectively in the tearing 丨 913 and 2, 故 故Sealing ". The peeling sealing film is the outer part of the force 1 can be present, so the flange is slightly smaller, and the length is equivalent to the shape.

In the second formation, the peeling start portion 21 is formed so that the width 'the width of the fingertip portion 21 is larger than the width of the peeling film 16, and the protruding line La has a knife line 22'. Thus, the peeling film 16 can surely leave the two stars at the position of the tangent line 22. : Peeling longitudinally. The peeling start portion 21 can provide coloring so that the tearing portion 19, including the cutting line 19a and the joint portion 19b, has been formed in the package ??? At the flange 12, the package 25 is, for example, tofu or _, i.e., in the genus 11, and finally the sealing film is adhered (Fig. 11). The process of packaging is slightly 彖 筮 筮 园 μ α α α α ...... ...... ...... ...... ...... ...... 。 。 。 。 。 。 。 。 。 。 。 。 。 In the above illustrative example, the bean, me ---------- one is trained from the situation. In the above illustrative example, in the process of two points of j point, the peeling _ knot is found to have 1> The process of the present invention is as follows. Figs. 12 to 14 show the method of providing the peeling start portion 21 which protrudes outward. At the time of opening, the peeling start portion w is pulled downward by the fingertip, and the peeling film 16 is divided into the notched tangential lines 22 (Fig. 13), =^17, 18) and gradually peeled off along the longitudinal direction of the flange 12. 1% of the peeling film 16 is exposed and connected (the Fig. 13 shows the #面面 of the sealing device). Therefore, the sealing film 15 can be peeled off at the joint of the tear portion 19 at 1%. When the joint is 1% torn|^, it is only used to the silk on the silk.

In contrast to the conventional case of peeling off the surface, the sealed package can be opened in a small amount. See Figure 14. 1 J to peel off the beginning of the department as the first! The position of the outward protrusion peeling start portion 21 shown in the figure is not limited to two points of the diagonal line, and can be as shown in Fig. 15. In this case, although the shop can be completely detached,:

The film can also be peeled off _ half way. Figure I6 shows the wire _ start part U 隅 隅 2 not only the length and the length of the four sides can be separated and peeled off, and the four sides are separated. The third example shows the peeling film I6, which is three-pointed on the outer surface of the packaging container u 1311970 ^ open S ^ type ^, in the outward direction of the flange 12 of the packaging container 11, 16 勹 1 & & 成The front end of the membrane 16'. Figure 18 is a dry table. 16 is on both sides of the cracked container 11, nearly W. The legend shows that the film is not separated from the film and formed at the flange 12, and the middle position of the escaped front surface is re-made from the film, and the corner is 'on the side two, with the same reference number. The common group No. 22 = shows that there is a peeling start portion 31. There is a peeling, and the beginning portion is a total of four identical cases. R The meaning of these embodiments is the same as those described in Figs. 15 and 16. However: the present invention also accommodates the container circle: the first container is attached to the container; the portion is densely closed; the lenticulum film 36 is tilted to provide a unique outward peeling opening circle 36. The whole can be peeled off. The $25 legend indicates that there is a = initial "W mesh (10). 'Reference number 42 is tangent, press; one =, yes!

The puncher is punched on the peeling film 53 Xiao (in Figure 28) It is a square shape in the '29th figure.) When the packaging container n of the formed split portion advances, the release film 16 is wrapped around the package. The molded product and the release film 16 (10) are integrated by a heater. The sheet and the film 16 are sheared together, so that the package can be mass-produced inexpensively. Reference _ 54 indicates the expected tangent. In the case where the second starting portions 21, 41 are present outside the flange 12, the difference between the shearing container 11 and the peeling film 16 is different. Therefore, the technique = 2? The container 11 and the peeling film 16 are cut at the same time. However, in the inner starting portion 31, 51, since the cutting dimension is the same in the packaging container u and the peeling J 16 , it is easy to cut the packaging container u and the peeling film 16 at a low cost. The advantage of the sealed container is that the scoop Ϊ3: the planar shape of the container closing portion is a quadrilateral shape, like the first-formation method, and the tearing portion 19 is formed on the quadrilateral shape, on the side or the four sides. In the table below the flange 12, -= = two sides, three sides, four sides of the tearing part of the shape = structure: on each side. In this case, since the peeling film % turns = the lower surface of 12, it can be individually adhered to each side of _, one, two sides or four 15 1311970 with a straight-type tape. The second embodiment of the invention shows that the second embodiment of the invention uses the linear type of glue to the embodiment shown in Fig. 36 ("the embodiment shown in Fig. 1"). The invention is applied to the formation of the opening of the opening. On all four sides of the flange 12 again # ί Mina 15 and other components, the reference number = the film 76 contains a long straight line Wei 76a, and the second one has a double secret. Its long and short straight film, one. The lower surface of the county 12 extends to the inner side portion 13 and the outer side portion 14 31. The pattern /-j / f type film 76 is configured to be parallel and intersect. In the first film, the short straight film, and the father 76c in which the films 76a and 76b overlap, the patterns are different from each other. The protruding film 76& is cut into a length such that the film 76a is outwardly directed to the straight line film 76a of the yf-if portion 71 at the edge of the flange 12, and is formed at the peeling start portion. The peeling start film 76 is inserted into the above space. Further, it is also used as the peeling of the reinforced tape. The cutting line 19 & The long linear film % and the short linear film 76b of the ^it film are slaves. Touching the wire, the long straight film 71 f/6b should be set to the peeling start portion 7 and the peeling start portion 7 can be set to change, and the range of - to eight should be set to the beginning of the peeling force. The short linear membrane overlaps, the level difference J is not avoided. However, since the thickness is as thin as, for example, _ to _ surface (4 〇 ~ lower μ; / Ιϋϊ heater, when the film is formed of a hot melt resin, the film is drilled separately from the film formed of the non-heat-meltable resin. In the case, ^, and filled in the gap. As a result, the packaging container enters the seal 16 1311970-like fe, no liquid leakage doubts. =, the sealing film 15 is dry in the packaging container ^ film 7-6a and short linear film like Two or six cases. That is, the sealing structure is almost similar to the one shown in Fig. 1 and the outer part; [4, the two parts of the inner part of the tearing portion 19 are four parts.
