Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and it will be apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the invention as defined and defined in the appended claims, and all matters produced by the invention using the inventive concept are protected.

For convenience of the following explanation of the package 2 and the outer film 1 according to the present embodiment, both surfaces in the width/length direction of the package 2 are referred to as a first side surface 21, both surfaces in the width/length direction are referred to as a second side surface 22, and both surfaces in the maximum thickness direction are referred to as a third side surface 23.

When wrapping up wrapping box 2, outer packaging film 1 of this scheme all can contact with each side of wrapping box 2, and for the convenience of the description to outer packaging film 1 of this scheme, this scheme divides outer packaging film 1 into three region, and the region that covers second side 22 and third side 23 on outer packaging film 1 is called first region 111, lies in first region 111 both sides, and the region that is used for covering a first side 21 respectively is called second region 112.

As shown in fig. 3 and 4, the outer packaging film 1 comprises a film 11 and at least one tear part 12, wherein tear sliders 13 which are equal in number to the tear parts 12 and extend out of the film 11 are connected to one side edge of the film 11; the tear part 12 comprises at least two tear lines 121; the tear lines 121 of the same tear portion 12 may have at least one intersection point, and the tear lines 121 disposed on the film 11 may be arc lines or straight lines.

When the tear string 121 of the same tear portion 12 has only one intersection point (i.e., the intersection point located on the tear slider 13), the tear string 121 extends on the film 11 without the intersection point, so that there is no inflection point in the tear string 121, and it is relatively easy to tear the film 11. When tearing the opening pull line 121 for the straightway, it is tearing film 11, and relative to the arc tearing pull line 121, the direction of force can not change, and it is the arc line relative to tearing pull line 121 when tensile, it can be easier to tear film 11.

The intersection point of one ends of all tear lines 121 of each tear portion 12 is located on one tear slider 13, and the other end extends toward the side away from the tear slider 13; when forming the tear portion 12, the ends of the same side of all the tear lines 121 of the same tear portion 12 may be connected together to form a point of intersection (refer to fig. 3); it is also possible to intersect the same side of all tear lines 121 of the same tear portion 12 adjacent the end (refer to fig. 4).

The tearing-port slider 13 at the side edge of the film 11 is mainly used for arranging the intersection point on the tearing-port part 12 on the tearing-port slider 13, and the tearing-port slider 13 extends out of the edge of the film 11, so that a user can conveniently and quickly find the opening end of the tearing-port part 12 and smoothly tear the tearing-port pull line 121 and the film 11.

As shown in fig. 3 to 5, a tear portion 12 is adhered to the film 11, and each tear portion 12 includes two tear lines 121; when the intersection point is located at the end of the two tear lines 121, the two tear lines 121 are in a "V" shape, refer to fig. 3; when the intersection point is adjacent to the ends of the two tear lines 121, the tear lines 121 on both sides of the intersection point are in a "V" shape, refer to fig. 4.

The tearing lines 121 are arranged in number and shape, so that the film 11 can be torn off easily, and meanwhile, the tearing lines can be saved.

When forming tear mouth portion 12, it can have a small segment to extend to prefer to tear a mouthful pull string 121 in nodical department on tearing a mouthful pull head 13, is wrapping up outer packaging film 1 of this scheme in packing carton 2 back like this, if when the film 11 border that tears a mouthful pull head 13 department just is in packing carton 2's border, intensity is greater than film 11 tears a mouthful pull string 121 and can make and tear a mouthful pull head 13 perk, can the person of facilitating the use find tear a mouthful pull head 13 fast like this to hold tear a mouthful pull head 13 smoothly.

Referring again to fig. 3 and 4, the outermost two tear lines 121 of each tear portion 12 (which are located on both sides of the central axis a of the film) are projected on the central axis a of the film 11 in the extending direction by more than 1/5 of the length of the film 11 in the extending direction.

The length of the outermost tear line 121 is set so that the tear portion 12 can be used to open at least 1/5 of the outer film 1 on the package 2 when the outer film 1 is torn off, and since the film 11 on the package 2 is torn off at least 1/5 of the circumference in the width direction, it is easier for a user to tear off the outer film 1 compared to a line-shaped tear line.

In practice, the projection of the two tear lines 121 (which are located on two sides of the central axis a of the film) on the central axis a of the film 11 in the extending direction of each tear portion 12 at the outermost side of the tear portion 12 is preferably equal to the length of the film 11 in the extending direction, and the tear portion 12 of such length can easily tear the whole film.

The tear line 121 of the present embodiment has a tensile strength greater than that of the film 11. Due to the strength, when the film 11 is torn off, after the tearing-opening pull head 13 is found on the outer packaging film 1, the tearing-opening pull line 121 on the tearing-opening pull head 13 is pulled forcibly, and the film 11 can be cracked first because the tensile strength of the film 11 is smaller than that of the tearing-opening pull line 121, so that the pulling line on the inner surface of the film 11 can be pulled out smoothly, and the outer packaging film 1 can be torn off.

Referring again to fig. 3, the end of all tear lines 121 remote from the tear slider 13 is flush with the other side edge of the film 11. Tear oral area 12 and adopt this kind of arrangement mode after, can make the both ends that tear mouthful stayguy 121 lie in film 11's both sides edge respectively, when wrapping up packing carton 2 like this, tear oral area 12 and span four sides of 2 width directions of packing carton, when tearing film 11, film 11 on the whole packing carton 2 will be opened for film 11 tears except that very convenient, and film 11 is torn the back simultaneously, is a whole almost, and the rubbish of being convenient for is picked up.

As shown in fig. 4, the tear line 121 of this embodiment need not be provided on the edge of the film 11 on the side away from the tear slider 13, and the outer film 1 can be easily removed as long as the tear portion 12 allows more than half of the outer film 1 to be smoothly removed.

As shown in fig. 3, the ends of two tear lines 121 (which are located on both sides of the film central axis a) away from the film central axis a are located on the ridge line b where the first region 111 and the second region 112 contact each other. After the arrangement, after the two ends of the tearing part 12 are respectively positioned on the edge of the film 11 and the tearing puller 13, when the outer packaging film 1 is dismantled, the outer packaging film 1 after the dismantling can still be connected into a whole, and the outer packaging film can be directly stripped from the packaging box 2, and the mode is a good realization mode for tearing off the outer packaging film 1.

As shown in fig. 3 to 6, the tear slider 13 is located in the region of 1/3 length in the middle of the side film 11, and in this way, when the outer packaging film 1 is torn off, the film 11 on both sides of the tear portion 12 can be subjected to substantially the same force, but this case is suitable for the case where only one tear portion 12 is provided on the film 11; further preferably, the tear slider 13 may be arranged in an intermediate position of the film 11.

As shown in fig. 5 to 7, the length of the first region 111 of the film 11 is greater than the sum of the widths of the two second sides 22 and the two third sides 23; and/or the sum of the widths of the two second regions 112 is greater than the width of the first side 21 of packet 2.

After the size of the film 11 adopts the arrangement mode of the upper section, the initial section and the tail end of the outer packaging film 1 can be partially overlapped, so that the packaging box 2 can be prevented from being exposed at the initial section and the tail end to influence the moisture-proof effect.

The detailed description of the outer packaging film 1 has been completed so far, and the following description follows a method for producing the outer packaging film 1, which comprises the steps of:

obtaining the external dimension of the package 2 to be packaged, and determining the width and length of the film 11 according to the external dimension;
