Description

Description A soft bag

[Technical Field]

The invention relates to the field of flexible packaging bags.

【Background technique】

In the prior art, a flexible package of a flexible material is often used to encapsulate a substance such as a solid, a liquid, or a fluid, and a sealing edge of a flexible package of a flexible material is produced by a heat sealing, pressing, bonding, or the like. The advantages of using flexible packaging are light weight, low cost and easy to transport. The disadvantages include the following: First, the speed and quantity of fluid material being poured out cannot be controlled. Second, if the flexible packaging bag is filled with large particles and sheet-like articles. Etc., when the user needs to take it by hand, it is neither convenient nor easy to cause contamination of the contents of the package.

[Summary of the Invention]

In order to overcome the deficiencies of the prior art, the present invention provides a flexible package bag which can control the flow rate or amount of a substance such as a fluid poured out from a flexible package.

When dumping the fluid material in the flexible bag of the prior art, each time it is dumped, because the storage amount is different, the user's tilting angle and strength are different, and the speed and quantity of the fluid substance are greatly different, and sometimes the discharge is too fast and excessive. Sometimes it is too slow or too little, so it is very meaningful to provide a flexible bag that can control the amount and speed of fluid material pouring. Although there are currently hard containers that can be quantitatively poured out, such as the Chinese patent application number 200720171328. However, the processing cost of the hard container is high, the process is complicated, and the low-cost, large-scale application is not utilized, and the flexible packaging has the characteristics of simple process, light weight, low cost, and convenient transportation. Therefore, the flexible packaging of the quantitative container is significant.

The existing flexible packaging bag is mainly made of paper, aluminum foil, fiber, plastic film and composite thereof, and the polygonal sealed container which is sealed by bonding, heat sealing and the like, has at least one sealing at the periphery thereof. On the side, the usual flexible bag has more than three sealing edges. Among them, ziplock bags and stand-up bags are currently more commonly used technologies. The invention provides a flexible packaging bag comprising at least one flexible packaging bag sealing edge and at least one opening portion or an opening to be opened, and the flexible packaging bag wall is sealed at the sealing edge of the flexible packaging bag to enclose an inner space of the flexible packaging bag, The utility model is further characterized in that: a blocking portion is further formed by a close fitting of the inner wall of the flexible packaging bag; the blocking portion divides an inner space of the flexible packaging bag into a storage cavity and a temporary storage cavity, wherein the temporary storage cavity and the storage cavity are respectively set In the near opening portion and the far opening portion of the flexible packaging bag, or near the opening portion and the distal opening portion, a passage is provided between the storage cavity and the temporary storage cavity.

The flexible bag body can adopt existing common structures, such as a ziplock bag, a stand-up bag, and the like. In some structures The opening portion may be provided with a tearable opening (pre-opening), which can be easily torn open when starting to use. If the flexible package is viewed from the front, the opening or the opening to be opened is disposed at the top of the flexible packaging bag, and the temporary storage cavity and the storage cavity are vertically distributed in the vertical direction, respectively.

Further, the blocking portion is a fixed barrier wire formed by bonding, pressing or heat sealing, and the sealing edge of the barrier wire and the flexible packaging bag adopt the same process, so the barrier wire can be sealed with the flexible packaging bag. The joint is formed at one time. The barrier line includes two ends: at one of the ends, the temporary storage chamber and the storage chamber are completely isolated, and at the other end, the passage between the storage chamber and the temporary storage chamber is left. The two ends of the barrier wire may be: one end in contact with the sealing edge of the flexible packaging bag, and the other end not in contact with the flexible packaging bag.

Further, the closer to the passage, the closer the barrier line is to the opening or the portion to be opened of the flexible package. When the flexible packaging bag is turned over, fluid material flows and concentrates toward the passage under the guidance of the barrier wire, and it is also convenient to "empty" the residual fluid material in the storage chamber.

Further, a refastenable structure or a container cover is provided at the opening of the flexible package to open and close the flexible package.

Further, the barrier line is a slanted straight line. When the flexible package is turned over, the "sloping slope" formed by the inclined straight line facilitates the flow of fluid material to the passage.

Further, the barrier line is a curve that is curved toward an opening portion or a portion to be opened of the flexible packaging bag.

Further, the barrier line is a fold line that is bent at both ends toward the opening or the portion to be opened. In order to discharge the fluid material in the temporary chamber, the flexible bag can be poured with a smaller tipping angle.

Further, further comprising a guiding portion formed by the inner wall of a part of the flexible packaging bag of the flexible packaging bag or closely adhering to the inner wall of the flexible packaging bag, the guiding portion being disposed on the side of the channel and blocking the same The portions are oppositely formed in a funnel shape, and the funnel-shaped outlet faces the opening portion of the flexible package or the portion to be opened. In order to flip the flexible package, the funnel formed by the guide and the barrier is beneficial for the concentration of fluid material to the passage.

When the guide portion is constituted by the inner wall of a portion of the flexible packaging bag of the flexible packaging bag, a portion of the sealing edge including the flexible packaging bag constitutes the guiding portion.

Further, the guiding portion is a fixed guiding barrier line formed by bonding, pressing or heat sealing. The guiding barrier and the sealing edge of the flexible packaging bag are subjected to the same process, so that the guiding barrier wire can be molded at one time with the sealing edge of the soft packaging bag.

Further, the guide line is a straight line or a curved line, and an opening near the opening of the flexible package or an end to be opened is above the blocking portion. In this way, it is more advantageous to direct all fluid substances to the temporary cavity.

Further, a first repeatable opening and closing structure is disposed on the inner wall of the packaging bag at the position of the blocking portion to block the barrier The inner wall of the bag at the position can be repeatedly fitted and separated.

Further, the inner wall of the bag at the channel position is provided with a second repeatable opening and closing structure so that the inner wall of the bag at the channel position can be repeatedly fitted and separated.

Further, all or part of the blocking portion is constituted by a movable repeating opening and closing structure that adjusts the size of the temporary cavity by the movable position. Further, the movable repetitive opening and closing structure includes a clip or a clip, and all or part of the blocking portion is formed by the clip or the clip being sandwiched on the wall of the flexible packaging bag.

In general, the partial blocking portion is made up of a movable repetitive opening and closing structure, which is more cost-effective to manufacture, and is easier to realize. Even when the size of the portion of the blocking portion is small, the user can pinch the corresponding position of the wall of the flexible packaging bag. The way to complete the adjustment of the size of the temporary cavity capacity.

Further, the utility model further comprises a support member installed in the temporary storage cavity, wherein the support member functions to support the temporary storage cavity of the flexible package as a fixed-size cavity, so that the quantitative fluid substance can be more accurate.

Further, the support member has a through hole and a support groove communicating with the through hole, one end of the through hole is provided with a container cover, and the support groove at the other end of the through hole is disposed in the temporary storage Within the cavity, and the slot of the support slot is opposite the channel.

Further, the repeatable opening and closing structure at the opening portion, the first repeatable opening and closing structure, and the second re-openable structure are a reproducible sealing structure (self-sealing structure) commonly used for ziplock bags.

The beneficial effects of the invention are as follows: by setting a temporary storage cavity in the upper part of the ordinary flexible package, the fluid substance in the flexible package is lifted and temporarily stored in the temporary storage cavity of the upper part of the flexible package during the reversed upright process, and the user is smaller when dumping The angle of inclination is used to discharge the fluid substance temporarily stored in the temporary cavity; or it is taken by hand near the opening. For a fluid substance with good fluidity, such as a liquid, during the reverse process of the flexible packaging, the fluid material in the temporary storage chamber can be immediately returned to the lower part of the flexible packaging, so that the function of quantitative pouring can be achieved. In addition, even if the fluid substance is continuously poured, the flow rate of the fluid material can be controlled by the restriction of the head space of the flexible package by the temporary cavity or the like, or by the limitation of the channel diameter.

It is also important that the barrier line forming the temporary cavity can be directly molded inside the flexible package - only the shape of the sealing die needs to be changed. When the traditional flexible packaging frame is sealed, the barrier wire can be formed at the same time without adding material. And the process flow, without changing the existing filling equipment, the cost of the invention and the traditional flexible packaging bag is almost the same.

As shown in FIGS. 8-1 to 8-6, compared with the embodiment 7, the difference of the flexible packaging bag 100 of the present embodiment includes: without the supporting member 221, the barrier line 110 having a fold line shape has no slope structure, and the first blocking line The barrier line segment between the end 111 and the first barrier line turning point 113, and the barrier line segment between the second barrier line turning point 114 and the second barrier line end 112 are both in a vertical direction or in a vertical direction, and the first blocking line The blocking line end between the turning point 113 and the second barrier line turning point 114 is horizontal or near horizontal, and the second blocking line end 112 is near the opening 245 of the flexible package 100, thereby between the storage cavity 210 and the temporary storage cavity 220. There are only channels 230 and no other channels.

As shown in Figs. 8-1 to 8-5, the flexible packaging bag 100 of the present embodiment can operate in a manner of controlling the amount of the discharged fluid substance 201; in addition, as shown in Figs. 8-1 to 8-4 and 8-6 As shown, it is also possible to control the rate at which the fluid material 201 exits, wherein the size of the passage 230 between the barrier line 110 and the flexible package wall 202 is related to the magnitude of the outflow velocity.

Example 9

As shown in FIGS. 9-1 to 9-6, the difference of the flexible packaging bag 100 of the present embodiment as compared with the embodiment 7 includes: the flexible packaging bag 100 has no supporting member 221, and has no second blocking wire end 112, and a barrier line between the second barrier line turning point 114 and the second barrier line end 112, but having a movable repeatable opening and closing structure 115, If it can be a clip or clip 115, the clip or clip 115 is clamped on the second barrier line turning point 114 and the flexible package wall 202, thereby equivalently forming a part of the barrier line of the barrier line 110, so that the temporary cavity 220 and the storage There are only channels 230 between the cavities 210 and no other channels. The clamping position of the clip or clip 115 is moved, so that the cavity space of the temporary cavity 220 is changed, that is, the number of fluid substances 201 that can be temporarily stored can be changed.

The manner in which the flexible pouch 100 operates to control the amount of the poured fluid substance 201 is similar to that of the embodiment 7. If it is desired to change the fluid substance 201 that is poured out each time, it is only necessary to change the sealing position of the movable repetitive opening and closing structure 115. The flexible packaging bag 100 can also operate in a manner to control the speed at which the fluid substance 201 is poured. As shown in FIGS. 9-7, the movable repetitive opening and closing structure 115 is opened, and another passage occurs between the temporary storage chamber 220 and the storage chamber 210. The fluid substance 201 flows out through the passage, the temporary chamber 220 and the opening 245.

Example 10

As shown in FIGS. 10-1 to 10-6, the difference of the flexible packaging bag 100 of the present embodiment is as follows: It has an opening 245 on the sealing edge 242 of the flexible packaging bag, and a cover is attached to the opening 245. 246, the flexible packaging bag 100 does not have a fixed separation storage compartment barrier line 110, but two flexible repeatable opening and closing structures 130 and a second repeatable opening and closing structure 140 are disposed on the flexible packaging bag inner wall 203 of the flexible packaging bag 100. When the first repeatable opening and closing structure 130 is closed, it can serve as a barrier line between the storage chamber 210 and the temporary storage chamber 220. Thus, as shown in FIG. 10-3, when the fluid substance 201 is poured, the second repeatable one is opened. The opening and closing structure 140, the fluid substance 201 enters the temporary cavity 220 through the channel thus formed, and then, as shown in FIG. 10-4, the flexible packaging bag 100 is placed, and the fluid substance 201 exceeding the capacity of the temporary cavity 220 passes through The passage formed by the opening of the repeatable opening and closing structure 140 re-flows into the storage chamber, and then, as shown in Fig. 10-5, the lid 246 is opened to pour a certain amount of the fluid substance 201.

Alternatively, as shown in Figures 10-6, the rate at which the fluid substance 201 exits can also be controlled by controlling the degree of opening of the first repeatable opening and closing structure 130 and the second repeatable opening and closing structure 140.
