Description

Visual bag for liquid soft package

Technical Field

The utility model relates to a liquid packaging container, in particular to a liquid flexible packaging visual bag.

Background

At present, the liquid is generally packaged by a large plastic bottle or a self-supporting bag. The existing self-supporting bag can be folded when not filled with liquid, and can be supported by the bottom when filled with liquid, and can stand on a platform by self to avoid the self-supporting bag from toppling.

For a large-capacity stand-up pouch (a stand-up pouch storing more than 3kg of liquid is large in capacity), the liquid with a large weight is poured out in a mode that a liquid outlet is positioned at the side, and finally the liquid is completely poured out along with the increase of the included angle between the liquid outlet and the vertical direction.

Referring to the front view of the stand-up pouch, the stand-up pouch includes an upper side for providing a liquid outlet, left and right sides, and a bottom side, the distance D between the connection point of the left and right sides of the stand-up pouch and the upper side and the liquid outlet is relatively long, and a certain residue remains at a position between the connection point and the liquid outlet after pouring. Since the shaking of the self-standing bag from side to side for storing a dangerous liquid is likely to cause splashing of the liquid, the self-standing bag is not allowed to be shaken from side to side when pouring the dangerous liquid.

In addition, when the liquid is poured out, the left side edge and the upper edge of the self-standing bag are subjected to a large liquid weight, and are easily damaged.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, the embodiment of the present invention provides a visual bag for liquid flexible package, which comprises a front sheet 1, a rear sheet 5, a bottom sheet, a left side inserting edge 2 and a right side inserting edge 3, wherein the bottom ends of the front sheet 1 and the rear sheet 5 are respectively connected with the bottom sheet, the front sheet 1 and the rear sheet 5 are bent upward and then connected with each other, and a liquid outlet is arranged at the upper end connection between the front sheet 1 and the rear sheet 5. The left side inserting edge 2 is provided with a first longitudinal inner crease which is arranged along the height direction of the left side inserting edge 2, the upper ends of the left side inserting edge 2 are connected together, the lower ends of the left side inserting edge 2 can be opened, the left side inserting edge 2 is respectively connected with the front piece 1, the rear piece 5 and the bottom piece, the right side inserting edge 3 is provided with a second longitudinal inner crease, and the left side inserting edge 2/the right side inserting edge 3 are respectively connected with the front piece 1, the rear piece 5 and the bottom piece to form a cavity capable of containing liquid. A visible window 31 is provided in the right insert edge 3.

Preferably, the visual window 31 may be provided with a scale.

Preferably, the viewing window 31 is symmetrical about the second longitudinal internal fold.

When liquid is injected into the visual bag of the liquid soft package, the upper ends of the inserting edges 2 on the left side are connected together, the lower end can be opened, the liquid is dispersed at the bottom under the action of gravity, the visual bag of the liquid soft package is integrally in an approximate triangular cone shape, and the visual bag of the liquid soft package can realize self-standing without other dependence. The upper end and the lower end of the right side inserting edge 3 can be opened to be matched with the visible window 31, so that a user can observe the allowance in the visible bag of the liquid flexible package conveniently. The upper end and the lower end of the right inserting edge 3 can be opened, so that the visible window 31 can be effectively prevented from being folded.

Further, two handle holes 32 are provided on the right insert side 3, the two handle holes 32 being symmetrical about the second longitudinal inner fold. Because the right inserting edge 3 can be opened, when the handle holes 32 are lifted, the gravity of liquid is shared by the two handle holes 32 at two places of fingers, the contact area of the fingers is increased, and the hand tightening is avoided.

Further, in order to connect the upper ends of the left inserting side 2 to each other, a connecting area 21 is formed at the upper ends of the left inserting side 2 and the front and rear sheets 1 and 5, and a plurality of punched holes 22 are formed in the connecting area 21. When anter 1 and left side are inserted limit 2, back part 5 and left side and are inserted limit 2 heat-seal and be in the same place, anter 1 and back part 5 can also be connected through punching a hole 22 for interconnect between anter 1, left side are inserted limit 2, the back part 5, and in the scope of joining region 21, anter 1, back part 5 and left side are inserted limit 2 and are cohered together completely.

When pouring liquid, use the liquid outlet to rotate anticlockwise as the center of rotation, the gravity of liquid most part this moment acts on joining region 21 department for joining region 21 has better joint strength, avoids joining region 21 to break because of bearing great gravity.

The adoption of the widening connecting area 21 instead of widening the connecting width of the left inserting edge 2 and the front and back sheets 1 and 5 can avoid the influence on the volume of the visible bag of the liquid flexible package caused by the increase of the connecting width of the left inserting edge 2 and the front and back sheets 1 and 5.

The aforementioned connection region 21 is formed with a first multi-fold line 23 on a side close to the liquid outlet, and the first multi-fold line 23 is gradually close to the liquid outlet from bottom to top to reduce the distance D from the left inserting edge 2 to the liquid outlet, thereby avoiding the accumulation of liquid near the liquid outlet.

Further, the right side is inserted limit 3 and is formed with the handle with anter 1 and back part 5 and set up the district, and handle hole 32 sets up in the handle sets up the district, and handle hole 32 is less than the position of punching a hole 22, guarantees when empting, and the visual bag of better lift liquid flexible package.

Further, a base with a rotary cover 4 is arranged at the liquid outlet, the base is used for communicating the liquid outlet, and the rotary cover 4 is used for sealing the liquid outlet.

Preferably, the left edge 2, the front panel 1 and the rear panel 5 in this application are made of a composite film with aluminum foil. The composite film with the aluminum foil means that any one layer of the composite film is an aluminum foil layer.

The right insert edge 3 is made of a transparent composite film containing PE material. Anti-ultraviolet agents such as anti-UVI auxiliary agents and the like can be properly added into the PE material, so that decomposition of light sensitive components in products is prevented, and further liquid fading is prevented.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
