[0039] Example 1

[0040] Please refer to Figures 1 to 7 This embodiment provides an easy-tear film, which includes a heat-sealing layer 10 and a barrier layer 20 connected to one side surface of the heat-sealing layer 10.

[0041] The heat seal layer 10 and the barrier layer 20 are stacked. When in use, the barrier layer 20 is disposed on the upper surface of the heat seal layer 10 (eg Figure 1 shown).

[0042] The barrier layer 20 includes a main body 23 and an easy-to-open ear 22. The main body 23 is used to cover the packaging opening 52, and the easy-to-open ear 22 extends outward from the main body 23. The easy-to-open ear 22 is arranged so that the user can grasp or pinch it, thereby further applying force to open the film layer.

[0043] The material of the heat-sealing layer 10 may be, for example, a food-grade polyester material or a polyolefin material, and the barrier layer 20 may be, for example, an aluminum foil or aluminized PET or other high-barrier materials.

[0044] In some embodiments, the size of the heat-sealing layer 10 is consistent with the size of the barrier layer 20; in other embodiments, the size of the heat-sealing layer 10 is smaller than the size of the barrier layer 20 to facilitate peeling off the film layer.

[0045] like Figure 1 The heat-sealing layer 10 includes a connecting portion 11 for connecting to the packaging opening 52, and the heat-sealing layer 10 also includes a partition 12 located inside the connecting portion 11, and the partition 12 and the connecting portion 11 can be selectively separated; when the easy-tear film is peeled off, at least a part of the partition 12 is separated from the connecting portion 11 to form an opening 13 (such as Figure 2 shown).

[0046] The above-mentioned "inside" can be understood as the inward direction on the same horizontal plane. Exemplarily, the connecting portion 11 is annular, and the partition 12 is located in the middle hollow part of the annular. The annular can be, for example, a circular ring or a square ring, or other annular geometric shapes.

[0047] The “selective separation” of the partition 12 and the connection part 11 can be understood as: before the film layer is uncovered, the partition 12 and the connection part 11 are in an integrally connected state; in the process of uncovering the film layer, the partition 12 and the connection part 11 are gradually separated until the partition 12 and the connection part 11 are completely separated, or the partition 12 and the connection part 11 are partially separated. The area where the partition 12 and the connection part 11 are separated forms an opening 13.

[0048] The heat-sealing bonding force between the connecting portion 11 and the packaging opening 52 > the bonding force between the separating portion 12 and the barrier layer 20, and the heat-sealing bonding force between the connecting portion 11 and the packaging opening 52 > the bonding force between the connecting portion 11 and the barrier layer 20. During the process of uncovering the film layer, the barrier layer 20 will separate from the connecting portion 11 along with the uncovering force applied by the user, and during the process of uncovering the barrier layer 20, when uncovering to the connection point between the connecting portion 11 and the separating portion 12, the barrier layer 20 will uncover the separating portion 12 together, so that the separating portion 12 and the connecting portion 11 are completely or partially separated. That is, whether the tearable film is in the uncovered state or the sealed state, the connecting portion 11 in the heat-sealing layer 10 is always connected to the packaging opening 52, and the opening 13 is formed by the separation of the separating portion 12 and the connecting portion 11.

[0049] In some embodiments, as Figure 3 shown, the separating portion 12 is in a closed shape, and in the uncovered state of the tearable film, the separating portion 12 is completely separated from the connecting portion 11. That is, during the process of applying force to the barrier layer 20, the barrier layer 20 uncovers the separating portion 12 completely and is completely separated from the packaging opening 52.

[0050] The specific form of the above-mentioned closed shape is not limited. For example, it can be a closed circle, semi-circle, square, or sector, etc. Exemplarily, the circumferential edge of the separating portion 12 can be a curve, a straight line, or a combination of a curve and a straight line, etc.

[0051] In other embodiments, as Figure 4 shown, the separating portion 12 has a notch 123, and in the uncovered state of the tearable film, the separating portion 12 is connected to the connecting portion 11 at the notch 123. That is, during the process of applying force to the barrier layer 20, the barrier layer 20 uncovers the separating portion 12 starting from the starting end 41 of the opening 13 until reaching the notch 123. At this time, the tearable film is partially separated from the packaging opening 52. This method is convenient for recycling the whole package.

[0052] The above-mentioned "starting end 41" refers to the end where the barrier layer 20 and the heat-sealing layer 10 are first separated during the uncovering process. The above-mentioned notch 123 can be set according to specific circumstances, including the specific setting position and size of the notch 123, which are not limited.

[0053] As Figures 5 to 7 shown, define the outermost edge of the projection of the connecting portion 11 on the plane where the packaging opening 52 is located as the first outer diameter 61, and define the innermost edge of the projection of the connecting portion 11 on the plane where the packaging opening 52 is located as the first inner diameter 62; define the outermost edge of the packaging opening 52 as the second outer diameter 63, and define the innermost edge of the packaging opening 52 as the second inner diameter 64.

[0054] At least a partial region of the starting end 41 of the corresponding opening 13 of the first inner diameter 62 is located inside the second inner diameter 64.

[0055] By arranging at least a partial region of the starting end 41 of the corresponding opening 13 of the first inner diameter 62 inside the second inner diameter 64, the region of the connecting portion 11 corresponding to the area between the first inner diameter 62 and the second inner diameter 64 is not heat-sealed to the packaging opening 52, and the required separating force is smaller. Thus, a smaller force can be used to separate the barrier layer 20 from the connecting portion 11 with the separating portion 12 at the first inner diameter 62 to form the opening 13.

[0056] The above-mentioned first inner diameter 62 includes a first region segment 111 facing the starting end 41 of the opening 13 and a second region segment 112 away from the starting segment of the opening 13. In some embodiments, the first region segment 111 is located inside the second inner diameter 64; the second region segment 112 may be located inside the second inner diameter 64 or flush with the second inner diameter 64.

[0057] The region where the above-mentioned first inner diameter 62 extends inward relative to the second inner diameter 64 can also serve as a blocking region 113, which can play a certain role in blocking the contents inside the package, thereby facilitating the avoidance of the direct ejection of the contents inside the package during the process of uncovering the film layer.

[0058] In some embodiments, the longest distance between the first region segment 111 and the second inner diameter 64 > the longest distance between the second region segment 112 and the second inner diameter 64.

[0059] The above-mentioned first outer diameter 61 can be flush with the second outer diameter 63, or the first outer diameter 61 can be located between the second outer diameter 63 and the second inner diameter 64, or the first outer diameter 61 can be located outside the second outer diameter 63.

[0060] The region where the connecting portion 11 is connected to the packaging opening 52 is a heat-sealed region. When the first outer diameter 61 is flush with the second outer diameter 63, the heat-sealed region can be understood as the region between the first outer diameter 61 (or the second outer diameter 63) and the second inner diameter 64; when the first outer diameter 61 is located between the second outer diameter 63 and the second inner diameter 64, the heat-sealed region can be understood as the region between the first outer diameter 61 and the second inner diameter 64; when the first outer diameter 61 is located outside the second outer diameter 63, the heat-sealed region can be understood as the region between the second outer diameter 63 and the second inner diameter 64.

[0061] In this embodiment, the shapes of the connecting portion 11 and the separating portion 12 are not limited. Exemplarily but not restrictively, they can independently be circular, square, triangular, other polygons, or irregular figures, etc.

[0062] In some embodiments, such as Figure 3As shown, the separating part 12 includes a transition area 121 and a main body area 122 connected in sequence. The transition area 121 is located on one side of the main body area 122 close to the starting end 41 of the opening 13. In some more specific embodiments, the radius of curvature of the main body area 122 is smaller than that of the transition area 121. A chamfer may be provided at the connection between the transition area 121 and the main body area 122. Through the above settings, it is more conducive to the separating part 12 being peeled off together with the barrier layer 20 during the peeling process. In addition, the separating part 12 may also not include a transition area.

[0063] In this embodiment, the shape of the main body part 23 of the barrier layer 20 can be adaptively set according to the shape of the packaging opening 52. For example, if the packaging opening 52 is circular, the main body part 23 of the barrier layer 20 can also be circular; if the packaging opening 52 is square, the main body part 23 of the barrier layer 20 can also be square.

[0064] The set shape of the easy-to-peel ear 22 is not limited and can be arched or toothed, etc. Among them, the toothed shape can be further divided into triangular teeth and square teeth, etc.

[0065] In some embodiments, such as Figure 3 and Figure 4 , the width of the easy-to-peel ear 22 extending outward along the edge of the main body part 23 gradually decreases. With this setting, it can be avoided that the film layer breaks during the peeling process. In some embodiments, the easy-to-peel ear 22 is arched, and the width of the easy-to-peel ear 22 extending outward along the edge of the main body part 23 gradually decreases, making the entire barrier layer 20 in a water droplet shape. Correspondingly, the easy-to-tear film as a whole also presents a water droplet shape.

[0066] In some other embodiments, such as Figure 6 and Figure 7 , the width of the easy-to-peel ear 22 extending outward along the edge of the main body part 23 is consistent.

[0067] In addition, the shapes of the barrier layer 20 and the easy-to-tear film can also be adjusted according to needs, and the present application does not make specific limitations on them.

[0068] Regarding the number of the easy-to-peel ears 22 provided, it can be only 1 (such as Figure 3 and Figure 6 ), or it can be multiple, such as 2 (such as Figure 7 ), 3 or more. When the number of the easy-to-peel ears 22 is 1, it is preferably connected to the edge of the main body part 23 close to the first area segment 111. When the number of the easy-to-peel ears 22 is multiple, the multiple easy-to-peel ears 22 can be continuously arranged or spaced apart.

[0069] In some embodiments, the connection length between the easy-to-peel ear 22 and the main body part 23 can be 1 / 6 to 1 / 2 of the perimeter of the main body part 23, such as 1 / 6, 1 / 5, 1 / 4, 1 / 3 or 1 / 2, etc. Within this connection length range, a better force application effect is achieved.

[0070] In some embodiments, the length that the easy-to-tear ear 22 extends outward from the edge of the body portion 23 can be 3 mm to 30 mm, such as 3 mm, 6 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 30 mm, etc., and can also be other values within the range of 3 mm to 30 mm.

[0071] In some embodiments, the area of the easy-to-tear ear 22 can be 90 mm 2 to 1600 mm 2 , such as 90 mm 2 , 100 mm 2 , 200 mm 2 , 400 mm 2 , 600 mm 2 , 800 mm 2 , 1000 mm 2 , 1200 mm 2 , 1400 mm 2 , or 1600 mm 2 etc., and can also be other values within the range of 90 mm 2 to 1600 mm 2 range.

[0072] With the above-mentioned extended length and area in cooperation, it is more convenient for the user to pinch and hold firmly, avoiding the problems of unfavorable force application and difficulty in uncovering the film layer caused by improper size of the easy-to-tear ear 22.

[0073] In some embodiments, such as Figure 6 and Figure 7 , the body portion 23 is provided with a tear line, and the tear line includes a first tear line 241 and a second tear line 242. The projection of the first tear line 241 on the plane where the packaging opening 52 is located is between the first inner diameter 62 and the second inner diameter 64. The projection of the second tear line 242 on the plane where the packaging opening 52 is located at least partially overlaps with the connection part between the connecting part 11 and the separating part 12 (the overlapping form includes point overlap or line overlap); the easy-to-tear ear 22 has a first contact point and a second contact point connected to the body portion 23. The first contact point is connected to one end of the first tear line 241, and the second contact point is connected to one end of the second tear line 242.

[0074] Taking the easy-to-tear ear 22 as an example of 1, such as Figure 6, after pinching the easy-to-tear ear 22 and applying force thereto, it can cause the barrier layer 20 to start separating from the connecting portion 11 of the heat-sealing layer 10 at the first contact point and the second contact point. Then, through the guiding action of the first tearing line 241 and the second tearing line 242, the separation area between the barrier layer 20 and the connecting portion 11 is gradually increased until reaching the position where the projection of the second tearing line 242 on the plane where the packaging opening 52 is located partially overlaps with the connection portion between the connecting portion 11 and the partitioning portion 12. The barrier layer 20 then separates from the connecting portion 11 together with the partitioning portion 12.

[0075] Taking 2 easy-to-tear ears 22 as an example, such as Figure 7 , they are respectively defined as the first easy-to-tear ear and the second easy-to-tear ear. Among them, the first easy-to-tear ear and the second easy-to-tear ear are respectively arranged on opposite sides of the packaging body 51. The two contact points of the first easy-to-tear ear connected to the body portion 23 are respectively connected to one end of the first tearing line 241 and the second tearing line 242, and the two contact points of the second easy-to-tear ear connected to the body portion 23 are respectively connected to the other end of the first tearing line 241 and the second tearing line 242.

[0076] In some embodiments, the easy-to-tear ear 22 is further provided with a hollowed-out area 221 (such as Figure 3 and Figure 4 shown). The hollowed-out area 221 can be, by way of example but not limitation, located in the middle area of the easy-to-tear ear 22, so as to evenly disperse the force applied during the uncovering process to avoid excessive force causing the easy-to-tear ear 22 to break. The size of the above-mentioned hollowed-out area 221 is preferably at least large enough to allow the fingertips of the fingers to hold it, so as to avoid the problem that the hand slips off the easy-to-tear film during the film uncovering process due to the smoothness of the film layer when applying force.

[0077] Among them, the shape of the hollowed-out area 221 is not limited. For example, it can be circular, elliptical or square, etc. In some relatively typical embodiments, the hollowed-out area 221 is a circle suitable for the fingers.

[0078] In some embodiments, at least one side surface of the easy-to-tear ear 22 is provided with an anti-slip structure. For example, an anti-slip structure can be provided on the upper surface of the easy-to-tear ear 22, or an anti-slip structure can be provided on the lower surface of the easy-to-tear ear 22, or anti-slip structures can be provided on both the upper surface and the lower surface of the easy-to-tear ear 22.

[0079] Among them, the anti-slip structure can be a contact point protruding from the surface of the easy-to-tear ear 22, or other structures such as anti-slip patterns that can increase the friction between the hand and the easy-to-tear ear 22. The specific form, quantity and its distribution on the easy-to-tear ear 22 of the anti-slip structure are not specially limited in this embodiment.

[0080] In some embodiments, the easy-to-tear film may further include a printed protective layer 30 (such as Figure 1As shown in the figure, the printed protective layer 30 is located on the surface of the barrier layer 20 on the side away from the heat-sealing layer 10.

[0081] The size of the printed protective layer 30 can be the same as that of the barrier layer 20, or smaller than the barrier layer 20.

[0082] Continuing from the above, in this embodiment, by setting the heat-sealing layer 10 into a selectively separable connecting portion 11 and a separating portion 12, and providing an easy-to-tear tab 22 on the barrier layer 20, a user can firmly hold the barrier layer 20 when uncovering the film layer. By applying force to the barrier layer 20, the separating portion 12 can be effectively separated from the connecting portion 11 in at least some areas under the bonding force of the barrier layer 20. During this process, the connecting portion 11 is always connected to the packaging opening 52. The above process can effectively uncover the easy-to-tear film with only a small amount of force.

[0083] Embodiment 2

[0084] The present utility model provides a packaging, which has the easy-to-tear film in the above-mentioned Embodiment 1.

[0085] As an example, referring to Figure 2 , the above-mentioned packaging includes a packaging body 51, the packaging body 51 has a packaging opening 52, and the easy-to-tear film is used to seal the packaging opening 52. Among them, the packaging body 51 can be in the form of a bottle or a cup, etc.

[0086] The contents in the packaging are not limited to liquids and solids, but can also be flowable contents with a certain viscosity.

[0087] In some relatively typical embodiments, the packaging can be a yogurt packaging.

[0088] Continuing from the above, the easy-to-tear film seals the packaging opening 52. When consumption is needed, only by holding the packaging body 51 with one hand, pinching the easy-to-tear tab 22 with the other hand and applying force to the film layer, as the barrier layer 20 and the heat-sealing layer 10 are continuously separated, the connecting portion 11 of the heat-sealing layer 10 remains connected to the packaging opening 52, and the separating portion 12 in the heat-sealing layer 10 attached to the barrier layer 20 is further separated from the packaging opening 52 to form an opening 13. The above process can effectively uncover the easy-to-tear film with only a small amount of force, which is convenient for consumption and also reduces or avoids the possibility of the hand slipping off the surface of the film. The packaging with the above-mentioned easy-to-tear film can facilitate the use by consumers.
