Aiming at the aim of the invention, the scheme adopted by the patent is as follows: a replenishing liquid packaging bag which is easy to tear and convenient to store and transport comprises a cavity and a heat sealing area sealed to form the cavity, wherein the packaging bag comprises a top corner, an opening part is arranged on the top corner, an easy-to-tear line is arranged on the opening part, the easy-to-tear line comprises a nick and a linear opening which is arranged in the heat sealing area and connected with the nick, one side edge of the top corner is connected with the nick, the linear opening extends towards the other side of the top corner, and the linear opening is separated from the other side edge of the top corner; after tearing open the top corner of the packaging bag along the nick and the linear opening, the opening part forms a convex filling part, and the top of the filling part is an opening communicated with the cavity.
The packaging bag adopting the structure does not need any tool, the packaging bag can be torn along the nick by hand, the linear opening can better guide a user to exert force, because after the nick is torn, the rear half part of the easy-to-tear line is difficult to control the direction of the force like tearing the nick, therefore, the linear opening which does not need to be torn and penetrates through the heat sealing area is arranged at the position, even if the linear opening is not connected with the edge of the packaging bag, a convex filling part can be formed after tearing, the opening at the top of the filling part is wrapped by the bottle mouth during filling, the bottle mouth is not easy to spill, the linear opening is not connected with the edge of the packaging bag, the opening of the filling part is formed by directly tearing the packaging bag, the contents of the packaging bag do not need to flow out through an additional flow guide device, the flowing can be kept smooth during pouring, the flow of the contents of the packaging bag cannot be limited, the contents of the packaging bag are not easy to remain, meanwhile, the opening which is not easy to be stuck together due to the effect of electrostatic adsorption and the pressure, the packaging bag is difficult to be arranged on both sides, the packaging bag during pouring, the packaging bag, the pouring process, the packaging bag is not needed to be extruded to be stacked, the packaging bag has high-discharging efficiency and the high-cutting-saving efficiency of the packaging bag is increased, and the packaging bag is also the packaging bag.
Further, the opening still includes easily tears the portion, easily tears the portion and locates the edge on that side at line shape opening place in the apex angle both sides, and the setting of line shape opening orientation easily tears the portion.
Set up the accessible like this and easily tear the portion and guide the user and tear to linear opening because tear just at the beginning along the nick and need guarantee the accuracy of the direction of exerting oneself, can not necessarily tear very well, but through the guide of easily tearing the portion, can be with the high probability at the beginning directly along easily tearing the portion and the linear opening is good tearing the partly of easily tearing the line, and can meet the department at linear opening and nick with stress concentration, tear the nick more conveniently.
Further, the apex angle both sides are short avris and long avris respectively, linear opening corresponds with the portion of easily tearing and establishes at the short avris, and the nick meets with long avris edge.
Because the supplementary liquid wrapping bag can consider its capacity when the heat-seal, the capacity is big more, the liquid of dress is more, but also can not fill up, need reserve certain space and empty, because long avris length of side is longer, can reserve bigger empty space with less liquid in comparison with short avris, consequently generally use the long avris of wrapping bag to be the side of empting, so, be located the linear opening and the easy tearing portion of wrapping bag short avris upwards, the user conveniently from easy tearing portion to linear opening power, and then tear the wrapping bag apex angle along the nick, form convex filling portion.
Further, the distance from the joint of the nick and the long side edge to the top of the top corner is larger than the distance from the easy-tearing part to the top of the top corner.
Because the long avris is for empting the side, and the nick meets with the long avris edge, so will let the whole of the filling portion that forms after tearing down the slope at the long avris, just be convenient for let the filling portion bearing empty on the bottleneck, consequently here with the distance that meets department to the apex angle top of nick and long avris edge set up to be greater than the distance of easily tearing portion to the apex angle top, greatly made things convenient for user's filling liquid.
Further, the apex angle both sides are the short avris and the long avris respectively, linear opening corresponds with the portion of easily tearing and establishes at the long avris, and the nick meets with the short avris edge.
It can be known from the above that, generally, the long side of the package bag is the pouring side, after tearing the top corner of the package bag along the easy-to-tear part and the linear opening, a good bearing part can be formed at the linear opening, so that the filling part can be conveniently supported on the bottle mouth for filling liquid, the nick can not be well guided to be torn, i.e. easily torn away from the predetermined path, if the nick is changed to be connected with the edge of the long side of the package bag, the nick can not necessarily form a good bearing part after being torn.
Further, the linear opening is recessed in a direction opposite to the apex angle.
The arrangement means that in the process of filling after the top corner of the packaging bag is torn, the edge of the bottle mouth can be clamped in the linear opening concave part, so that the filling part is not easy to slide out, and the bottle mouth is easy to align.
Further, the linear opening is gradually increased in distance from the top of the top corner of the package bag from the end connected to the notch to the other end.
The linear opening gradually far away from the top corner of the packaging bag makes two sides of the filling part wider, thereby facilitating filling of the small-caliber bottle mouth.
Further, the linear opening increases and then decreases in distance from the top of the top corner of the packaging bag from the end connected with the nick to the other end.
In this way, the linear opening forms a distinct recess in the direction of the apex angle, so as to form a deeper recess for supporting the pouring element on the bottle mouth for pouring.
Further, the shortest distance between the linear opening and the cavity is 1-3 mm.
The closer the linear opening is to the cavity, the easier the packaging bag is torn, the use experience of a user is influenced, and the too far distance can cause the caliber of the top opening of the filling part to be too large, so that the filling is not convenient to adapt to a small-caliber bottle mouth.
Further, the shortest distance between the linear opening and the easy tearing part is 1.5-2.5 mm.
The closer the linear opening is to the easy-to-tear portion, the easier it is to damage the packaging bag due to external force in the transportation and storage process, and the too far away may lose the guiding function of the easy-to-tear portion corresponding to the linear opening when tearing, which is inconvenient for the user to tear the packaging bag according to the established route.
Further, the score is formed by a plurality of hole connecting lines which do not penetrate through the cavity. The distance between the holes is short, the force born by the middle is small, and when a user applies force at the tail end of the nick, the packaging bags can be torn one by one along the holes on the nick, so that the packaging bags are easier to tear.
Further, the score is formed by combining more than two score lines, and the score lines are formed by connecting a plurality of holes which do not penetrate through the cavity. Above-mentioned structure can reduce the maloperation, even if the user tears a ruling carelessly, can also tear the wrapping bag along another ruling, and in addition, the ruling is more, and the nick department structure is unstable more, and the user can tear the wrapping bag with littleer power, avoids appearing tearing the wrapping bag or making the condition that the content spills excessively hard.
Furthermore, the width of the top opening of the pouring part is between 0.5 and 4 cm. The most common diameters of the filling containers on the market are 2.5cm,2.8cm and 3.5cm, so that the opening width can enable the filling part to adapt to bottle mouths of most containers, and the practicability is increased.
