Ensure to be not easy to damage while packaging bag is conveniently laying during storing and transport again.
For foregoing invention purpose, scheme is used by this patent：A kind of replenisher bag for not only easily tearing but also facilitating accumulating
Pack, including cavity and sealing form the heat-sealable area of cavity, and the packaging bag includes a drift angle, and drift angle is provided with opening portion,
The opening portion is provided with easy-torn line, and easy-torn line includes indentation and is located at heat-sealable area, and the wire opening to connect with indentation, drift angle
One lateral edges connect with indentation, and wire opening extends toward drift angle opposite side, but wire opening is separated by with another lateral edges of drift angle；Edge
After indentation and wire opening tear packaging bag drift angle, the opening portion forms the perfusion portion of protrusion, is connection chamber at the top of perfusion portion
The opening of body.
Any instrument is not required to using the packaging bag of this structure, packaging bag can be torn along indentation, wire opening with hand, and
Wire opening preferably can guide user to exert oneself, because after tear notches, the latter half of easy-torn line is difficult to as tear notches one
The direction of sample controling power, therefore, the wire opening through heat-sealable area that need not be torn is set herein, even if wire opening does not have
With packaging bag side edge, but can guide tear after form the perfusion portion of protrusion, allow bottleneck to wrap perfusion portion top during perfusion
The opening in portion, it is not easy to spill, and wire opening is not directly to tear packaging bag with packaging bag side edge, the opening in perfusion portion
And formed, packaging bag content need not flow out through other guiding device, can keep flowing when toppling over it is smooth, without limitation on bag
Content logistics capacity is packed, is not easy to remain packaging bag content, while the opening for the aperture efficiency guiding device directly torn is big, both sides
It is not easy, because the effect of Electrostatic Absorption and pressure is sticked together, packaging bag to be toppled over when filling, it is not necessary to which user is to bag
Pack is extruded the situation for open the opening of adhesion, avoiding and causing the injection of packaging bag content to be spilt because of extruding, and
And only need to set indentation in packaging bag in process of production and be punched into wire opening, production efficiency is high and cost is low, then
The packaging bag of person's this patent is not additionally provided with the guiding device or other structures of protrusion, simple in construction, during shipping storage
Easily stack, increase space availability ratio and conevying efficiency.
Further, the opening portion also includes easily tearing portion, and the easily portion of tearing is located at that where wire opening in drift angle both sides
The edge of side, and wire opening is set towards the easy portion of tearing.
So setting can guide user to tear to wire opening by easily tearing portion, because tearing needs along indentation at the very start
Ensure the correct of power thrusts, differ and surely tear very well, but by easily tearing the guiding in portion, can maximum probability at the beginning
When directly along easily tearing portion and wire opening preferably tears a part for easy-torn line, and can by stress concentration in wire opening and
Indentation joint, more easily tear notches.
Further, drift angle both sides are respectively short brink and long side, and the wire opening and the easy portion of tearing are correspondingly arranged at short
Avris, indentation and long side side edge.
Because replenisher packaging bag can consider its capacity in heat-sealing, capacity is bigger, and the liquid of dress is more, but can not
Fill and toppled over, it is necessary to reserve certain space, because the long side length of side is longer, less liquid can be used compared to short brink
Body reserves bigger space of toppling over, therefore typically using the long side of packaging bag to topple over side, it is so, short positioned at packaging bag
The wire opening of avris and easily to tear portion upward, user is convenient to be had an effect to wire opening from easily tearing portion, and then tears packaging along indentation
Bag drift angle, form the perfusion portion of protrusion.
Further, the indentation is more than with the distance at the top of the joint to drift angle of long side lateral edges easily tears portion to drift angle
The distance at top.
Because long side is topples over side, and indentation and long side side edge, thus to allow tear after the perfusion portion that is formed
It is overall need down to tilt in long side, be just easy to allow perfusion portion support on bottleneck to be toppled over, therefore here by indentation
It is set greater than easily tearing the distance at the top of portion to drift angle with the distance at the top of the joint to drift angle of long side lateral edges, greatly place
User's filling liquid.
Further, drift angle both sides are respectively short brink and long side, and the wire opening and the easy portion of tearing are correspondingly arranged at length
Avris, indentation and short brink side edge.
It will be recalled from above that long side typically using packaging bag is topples over side, along easily tearing portion and wire opening by packaging bag top
After angle is torn, it can be formed at a good support in wire opening, easily fill perfusion portion support on bottleneck
Liquid is filled, and indentation differs and is surely directed to tear well, namely predefined paths are easily torn off, if converted to indentation and packaging
Connecting for bag long side lateral edges, then just can not necessarily form at preferable support at indentation after tearing.
Further, the wire opening is recessed to the direction opposite with drift angle.
So set mean carried out after tearing packaging bag drift angle it is filling during, can make at wire open depression
Bottleneck edge card wherein, makes perfusion portion be not easy to skid off, and be easy to align with bottleneck.

It is filling.
Further, the wire opening is from the one end to connect with indentation to the other end, its with the top of packaging bag drift angle
Apart from first increases and then decreases.
So, wire opening forms obvious depression to drift angle direction, to form deeper depression to make perfusion portion
Support carries out filling on bottleneck.
Further, the wire opening and the beeline of cavity are 1 to 3mm.
Wire opening is nearer from cavity, more easily tears packaging bag, influences the usage experience of user, and filling can be allowed by being too far away from
The open-topped bore in note portion is too big, be not easy to adapt to small-bore bottleneck carry out it is filling.
Further, the wire opening and the beeline for easily tearing portion are 1.5 to 2.5mm.
Wire opening is nearer from portion is easily torn, easier that packaging bag is damaged because of external force during shipping storage, from
It can far lose when tearing very much that easily the portion of tearing corresponds to the guiding function of wire opening, be not easy to user according to set route to tear bag
Pack.
Further, the indentation is formed by multiple hole lines for not penetrating cavity.The distance between Kong Yukong is short, middle
The dynamics that can be born is small, when user exerts oneself in indentation end, can be torn one by one along the hole on indentation
Packaging bag, packaging bag is set to be more easy to tear.
Further, the indentation is combined by the groove of more than two and formed, and the groove does not penetrate cavity by multiple
Hole line is formed.Said structure can reduce maloperation, and a groove is torn off even with person's imprudence, can also be along another
Groove tears packaging bag, in addition, groove is more, structure is more unstable at indentation, and user can be torn with smaller power and be packed
Bag, avoids the occurrence of the firmly excessive situation torn packaging bag or spill content.
Further, the perfusion portion open top width is between 0.5 ~ 4cm.The container filling of in the market is most common
Bore is 2.5cm, 2.8cm and 3.5cm, and therefore, the A/F can make the bottleneck of the most of container of perfusion portion adaptation,
Increase practicality.More preferably a kind of A/F is 0.8 ~ 2.5cm.
