Abstract

A flexible packaging container comprises a container body (1) and a top sealing edge (2). The container body (1) has a bottom edge (11) located at the bottom thereof. The top sealing edge (2) is arranged at the top of the container body (1). A block line (13) is formed in the container body (1). The block line (13) extends from the top sealing edge (2) to the bottom edge (11). The block line (13) separates the inside of the container body (1) into a main cavity (14) on the left and a pouring channel (15) on the right. The cross section of the pouring channel (15) is smaller than the cross section of the main cavity (14). A pouring port (151) for a fluid to flow out is disposed at the top of the pouring channel (15). The bottom of the pouring channel (15) is in communication with the main cavity (14) through a fluid inlet (152). The narrow pouring channel limits the pouring speed and the pouring amount of the fluid material in the container, and prevents the problem that too much fluid material is poured out in each pouring action.

Description

Flexible packaging container

Technical field

The present invention relates to flexible packaging containers, especially flexible packaging bags having at least one edge seal.

Background technique

The existing flexible packaging containers for solid-liquid fluid materials are generally made of a flexible material, and the edges thereof are made by heat sealing, pressing, bonding and the like. The container has the advantages of being light, low in cost and easy to transport. One of the disadvantages is that each time it is dumped, because the user's tilting angle and shaking strength are different, the speed and quantity of fluid substance discharge are very different, and sometimes it is discharged at once. Fast, too much, causing waste; sometimes it is too slow, too little, and needs to be dumped many times, causing great trouble to users.

technical problem

The present invention provides a flexible packaging container capable of effectively limiting fluid drainage speed and drainage.

Technical solution

The invention provides a flexible packaging container comprising a container body and a top sealing edge, the container body having a bottom edge at a bottom end thereof, the top sealing edge being disposed at a top end of the container body, the container body being formed with a barrier line The barrier line extends from the top sealing edge to the bottom edge, and the barrier line divides the interior of the container body into left and right main chambers and drainage channels, and the cross section of the drainage channel Less than the cross section of the main chamber, the top end of the drain passage is provided with a drain port for discharging fluid, and the bottom of the drain passage communicates with the main chamber through the inlet port. The formation of the barrier wire may be sealed and formed by the same bonding, heat sealing and the like as the sealing of the flexible packaging container.

The top sealing edge and the container body enclose a sealed space, and the inside of the container body corresponds to the sealed space.

The cross section corresponds to a horizontal section. One side of the drain channel is the right side, and one side of the main chamber is the left side.

The flexible packaging container may be a self-sealing bag, and may be a stand-up pouch or a flexible pouch having a removable lid on the top edge and/or the upper portion of the drainage channel.

The top sealing edge may be integrally formed with the container body by sealing, heat sealing or pressing.

When measuring, the container body is placed upright, and the fluid in the main chamber enters the bottom of the drainage channel through the inlet port; when discharging, the container body is rotated to be inverted, and the bottom fluid flows along the drainage channel and passes through the row. The flow port is discharged.

The top sealing edge or the container body is provided with a tearable opening corresponding to the position of the drainage opening, and the easy tearing opening is torn when starting to use.

The top edge or the container body is provided with a cover at a position corresponding to the discharge port, and when in use, the cover is opened (removed).

When there are a plurality of sieve holes, they are distributed in a single row in the longitudinal direction. The mesh is adapted to the size of the fluid particles and is slightly larger than the size of the fluid particles.

By providing the mesh holes, the amount of fluid material entering the bottom of the drain passage (storage chamber) can be effectively limited.

Further, a position of the bottom edge corresponding to the barrier line is provided as a recess as the inlet. The left and right edges of the recess extend beyond the left and right edges of the barrier line, and the lowest point of the recess is lower than the bottom edge to form a U-shaped channel or other shaped channel.

By extending the barrier line, it is equivalent to extending the inflow opening of the drainage channel to the opposite corner of the drainage opening. The elongated barrier line and the barrier line have an included angle in the longitudinal section.

By extending the inflow port of the drainage channel to the opposite corner of the discharge port, the flow of the fluid substance in the main chamber and the drainage channel can be cut off in the shortest time when the container is dumped, thereby ensuring quantitative accuracy.

By providing an extended barrier line and forming an extended channel, the flow direction of the fluid can be effectively changed to extend the flow path of the fluid.

By providing an extended barrier line and forming an extended channel, the fluid material entering the temporary cavity can be prevented from being too fast or too large for control and quantification of the fluid material as it enters the temporary cavity.

Further, the restricting member is selected from the group consisting of: a first restricting member for restricting fluid flow at the inlet port, a second restricting member for restricting fluid flow at the drain port, and for restricting the inside of the drain passage A third limiting component of fluid flow. That is, the first, second, and third restriction members can be used individually or in combination as required.

Further, the first limiting member and the second limiting member are respectively disposed on the barrier line and the top sealing edge, and the first limiting member and the second limiting member are both re-sealable.

Further, the container body is provided with the third restricting member, and the third restricting member is a resealable or removable clip. This clip can also be referred to as a clip.

The on/off control of the fluid flow can be achieved by providing the first, second and third restriction members.

Further, the bottom of the drainage channel has a temporary cavity with an increased cross section. Through the temporary cavity, it is convenient to achieve a substantial quantification of the fluid during the measurement.

Further, a hard support body can be implanted in the drainage channel, and the rigid support body can support the drainage channel in a fixed shape.

Further, the side wall of the drainage channel has a scale mark for use by the user for quantification. That is, a scale mark is provided at a position corresponding to the fluid passage on the outer surface of the container body.
