Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of packaging technology, and more specifically, to an upright packaging bag for containing particulate detergent products. Background Technology

[0002] Typically, granular detergents such as laundry powder are sold in bags made of waterproof or water-resistant flexible film. The most common granular detergent bags are rectangular pillow-shaped, formed by sealing two rectangular sheets together. When these detergent products are sold in physical stores, due to the flat shape of the bags, they are usually stacked for storage or shelf display. The detergent granules in the bottom bag are compressed and no longer fluffy, making it inconvenient to pour out and reducing consumer comfort. Furthermore, this stacked shelf arrangement makes it difficult for consumers to quickly identify and retrieve the products, hindering sales. The flat shape of the granular detergent bags also makes them inconvenient for everyday storage.

[0003] On the other hand, some other products on the market (such as beverages and food) use stand-up pouches, allowing the pouches to be placed upright on shelves and in consumers' homes for convenient storage. However, for granular detergent products that often require large-capacity packaging, such stand-up pouches present a series of potential problems: Firstly, the detergent granules at the top of the pouch are compressed by gravity, causing the lower granules to become less fluffy, making them difficult to pour out and prone to clumping, thus reducing consumer comfort. Secondly, excessive air can be introduced during filling of stand-up pouches, and the formulation of some granular detergent products may also generate gas during storage. This means that shaking or external impact during transportation may cause the overinflated pouches to rupture.

[0004] Therefore, there is a need for a packaging bag with an improved configuration that allows it to stand upright easily after containing granular solids, while also keeping the granular solids inside loose and easy to pour out and less prone to clumping after standing upright for a long time, and also reducing the possibility of breakage during transportation. Summary of the Invention

[0005] The purpose of this disclosure is to address at least one aspect of the aforementioned problems and deficiencies existing in the prior art.

[0006] According to one aspect of this disclosure, a stand-up pouch for containing particulate detergent products is provided, comprising a first sheet, a second sheet, and a insert. The bottom edges of the first sheet and the second sheet are respectively bonded to the periphery of the insert. The remaining portions of the edges of the first sheet and the second sheet are bonded to the remaining portions of the edges of the second sheet, thereby forming a receiving space of the pouch. The particulate detergent products have a median weight particle size of 250 μm to 1000 μm and a bulk density of 0.3 g / cm³. 3 Up to 0.9 g / cm 3 The insert comprises a plurality of micropores, wherein the plurality of micropores has the following characteristics: a) the number of micropores is per 100 cm 2 a) 0.5-6 micropores on the bottom of the area; b) the average equivalent diameter of the plurality of micropores is 0.15 mm to 0.5 mm.

[0007] According to an exemplary embodiment of this disclosure, the plurality of micropores further have the following characteristics:

[0008] c) The plurality of micropores are distributed substantially symmetrically on both sides of the long axis of the insertion base with respect to the long axis of the insertion base;

[0009] d) The cross-sectional shape of the plurality of micropores is selected from: circular, triangular, rhomboid, polygonal, slit-shaped or a combination thereof.

[0015] b) The average equivalent diameter of the plurality of micropores is 0.2 mm to 0.4 mm;

[0016] c) The plurality of micropores are distributed in two rows in a substantially symmetrical manner with respect to the long axis of the insertion base on both sides of the long axis of the insertion base;

[0017] d) The cross-sectional shape of the plurality of micropores is selected from: triangle, rhombus, polygon, slit shape or a combination thereof;

[0018] e) The plurality of micropores are formed by piercing the insertion base with a needle having a substantially circular cross-sectional shape, the circular needle having a cross-sectional diameter of 0.25 mm to 0.5 mm; and

[0019] f) At least 50% of the micropores are formed from the outside to the inside.

[0020] According to an exemplary embodiment of this disclosure, the median weight particle size of the particulate solid is 250 μm to 950 μm, preferably 300 μm to 850 μm; the bulk density is 0.35 g / cm³. 3 Up to 0.8 g / cm 3 0.4g / cm 3 Up to 0.8 g / cm 3 .

[0021] According to an exemplary embodiment of this disclosure, the weight of the granular detergent product contained in the packaging bag is greater than 1 kg, preferably from 1.2 kg to 10 kg, and more preferably from 1.5 kg to 5 kg.

[0022] According to an exemplary embodiment of this disclosure, at least a portion of the edges of the first sheet and the second sheet are joined together to form an edge banding with a width of 8 mm to 12 mm.

[0023] The bottom edges of the first sheet and the second sheet are respectively joined to the periphery of the insert to form an edge band with a width of 8mm to 12mm.

[0024] The ratio of the width to the height of the first sheet and the ratio of the width to the height of the second sheet are both within the range of 1.2-1.5.

[0025] According to an exemplary embodiment of this disclosure, the first sheet, the second sheet, and the insert each include a plurality of composite material layers, wherein the plurality of composite material layers include a uniaxially oriented polyethylene layer, a biaxially oriented polyethylene layer, and a nylon layer.

[0026] According to an exemplary embodiment of this disclosure, the insert can be folded in half and sandwiched between the first sheet and the second sheet, so that the entire packaging bag forms a flat shape, wherein the width of the first sheet and the second sheet of the packaging bag is 350 mm to 420 mm and the height is 240 mm to 300 mm, and the height of the insert after being folded in half is 30 mm to 70 mm.

[0027] According to an exemplary embodiment of this disclosure, the top corner of the packaging bag is provided with a first inclined edge that slopes toward the top center line of the packaging bag, and the packaging bag also includes a handle, which is disposed at the first inclined edge and the grip portion of the handle is inclined toward the top center line of the packaging bag.

The packaging bag also includes a mouth portion disposed at the second inclined side. The axis of the mouth portion is inclined relative to the top of the packaging bag, and the opening of the mouth portion faces away from the bottom of the packaging bag.

[0029] According to an exemplary embodiment of this disclosure, the mouth is rigid and cylindrical in shape, wherein the diameter of the cylinder is 21 mm to 28 mm.

[0030] One advantage of this disclosure is that the packaging bag can be easily stood upright after containing granular solids, and even after prolonged standing (especially after transportation), it retains the granular solids inside, making it easy to pour. Without being limited by theory, the inventors are confident that the special design of the micropores on the packaging bag of this disclosure allows for both proper air intake and exhaust during transportation (i.e., avoiding excessive exhaust similar to vacuuming), thereby preventing the detergent particles from being compacted and subsequently clumping.

[0031] Another advantage of this disclosure is that the packaging bag reduces the possibility of breakage due to external forces during transportation. Without being limited by theory, the inventors are confident that the special design of the micropores in the packaging bag of this disclosure allows for proper air release during transportation, preventing over-inflation.

[0032] Another advantage of this disclosure is that the special design brings a balance between exhaust and intake.

Specifically, the width D of the first sheet 20a and the second sheet 20b is 420 mm, the height H is 320 mm, and the height h of the folded insert 20c is 65 mm. The number of micropores is [number missing] per 100 cm². 2 The area of ​​the insertion base is approximately 2.9.

[0070] As shown in the figure, the top corner of the packaging bag 20 is provided with a first inclined side 25 that slopes towards the top center line of the packaging bag 20. The packaging bag 20 also includes a handle 28, which is located at the first inclined side 25 and the gripping part of the handle 28 is inclined towards the top center line of the packaging bag 20. The handle 28 is rigid and roughly ear-shaped.

[0071] In an exemplary embodiment according to this disclosure, the top corner of the packaging bag 20 is provided with a second inclined side 26 that slopes toward the top centerline of the packaging bag 20. The packaging bag 20 also includes a spout 27 disposed at the second inclined side 26. The axis of the spout 27 is inclined relative to the top of the packaging bag 20, and the opening of the spout 27 faces away from the bottom of the packaging bag 20. The spout 27 is rigid and has an overall cylindrical shape. The spout 27 is configured to dispense the contents contained in the packaging bag 20 (in an exemplary embodiment, granular laundry detergent) via the spout 27. The top edge 22 of the packaging bag 20 is connected to a first side edge 23 via a first inclined side 25, and a handle 28 is formed near the first inclined side 25. Meanwhile, the top edge 22 of the packaging bag 20 is connected to a second side edge 24 via a second inclined side 26, and the spout 27 is attached to the second inclined side 26. Preferably, the spout axis A1 of the spout 27 may be perpendicular to the second inclined side 26.

[0072] According to other embodiments of this disclosure, the size of the packaging bag can be adjusted. For example, in the exemplary packaging bag shown in FIG2, the width D of the first sheet 20a and the second sheet 20b can be 350mm to 420mm, the height H can be 240mm to 300mm, and the height h of the folded bottom 20c can be 30mm to 70mm. Accordingly, the number, position, and arrangement of the micropores can also be adjusted accordingly based on the size changes.

[0073] Specifically, according to an example embodiment of this disclosure, in the exemplary packaging bag shown in FIG2, the width D of the first sheet 20a and the second sheet 20b can be 350mm, the height H can be 260mm, and the height h of the insert 20c after being folded can be 55mm. The insert can be provided with two rows of a total of eight micro-holes, which are symmetrically distributed with respect to the long axis of the insert.

[0074] Specifically, according to another exemplary embodiment of this disclosure, in the exemplary packaging bag shown in FIG2, the width D of the first sheet 20a and the second sheet 20b can be 380mm, the height H can be 280mm, and the height h of the insert 20c after being folded can be 55mm. The insert can be provided with two rows of a total of eight micro-holes, which are symmetrically distributed with respect to the long axis of the insert.

[0075] Figure 3 is a cross-sectional schematic diagram of the micropores provided on the insert of an upright packaging bag according to an exemplary embodiment of the present disclosure. Figure 3A It has a circular cross-section. Figure 3B It has a triangular cross-section. Figure 3C It has a rhomboid cross section. Figure 3DThe cross-section is slit-shaped. In some particularly preferred embodiments, the micropores on the insert of this disclosure are formed by piercing the insert with a needle of substantially circular cross-section, the diameter of which is 0.2 mm to 0.6 mm. In particular, the needle may be heat-treated or not before piercing, preferably not. Without being theoretically limited, it is believed that the micropores on the insert of this disclosure, when having preferred cross-sectional shape, size, number, position (e.g., symmetrical distribution relative to the long axis of the insert), and / or micropore orientation, allow for proper air intake while venting during the transport of the packaging bag (i.e., without excessive venting similar to vacuuming), thereby preventing the detergent particles from being compacted and also preventing the packaging bag from breaking.

[0076] According to this disclosure, the first sheet and / or second sheet and / or insert of the packaging bag may be made of multiple or two composite film layers. The inner layer is in contact with the granular detergent contained in the packaging bag, while the outer layer forms the outermost surface of the packaging bag. For example, in an embodiment employing multiple composite film layers, the outer layer is preferably polyester, the inner layer is preferably polyethylene, and the middle layer is preferably nylon. In another embodiment employing multiple composite film layers, the outer layer is preferably uniaxially oriented polyethylene, the inner layer is preferably low-density polyethylene, and the middle layer is preferably biaxially oriented polyethylene. In an embodiment employing two composite film layers, the outer layer is preferably polyester, and the inner layer is preferably polyethylene. In another embodiment employing two composite film layers, the outer layer is preferably nylon, and the inner layer is preferably polyethylene. Of course, in other embodiments, the first sheet and / or second sheet and / or insert of the packaging bag may also be made of any suitable flexible film layer and / or composite film layer as needed, and this disclosure is not limiting.

[0077] Furthermore, the first and / or second sheets and / or part, multiple parts, or all of the insert of the packaging bag may be coated or uncoated, treated or untreated, processed or unprocessed in any manner known in the art. The flexible film and / or composite film materials used to manufacture the packaging bags disclosed herein may be formed in any manner known in the art and may be joined together using any kind of joining or sealing method known in the art, including, for example, heat sealing (e.g., conductive sealing, pulse sealing, ultrasonic sealing, etc.), welding, curling, bonding, adhesion, etc., and any combination thereof.

[0078] Experimental data show that when the preferred design of the upright packaging bag of this disclosure is adopted, the technical objectives can be achieved: 1) to accommodate a large volume of granular detergent, 2) the packaging bag can be placed upright and transported, 3) the packaging bag does not clump together due to excessive air release during transportation, 4) the packaging bag does not rupture due to over-inflation during transportation, and / or 5) no powder leakage occurs.

[0079] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved upon. The structures described in the various embodiments can be freely combined without causing any conflict in structure or principle.

[0080] Although the present disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of the present disclosure and should not be construed as a limitation thereof.

[0081] While some embodiments of the concept of this disclosure have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the overall concept of this disclosure, the scope of which is defined by the claims and their equivalents.

[0082] It should be noted that the word "comprising" does not exclude other elements or steps, and the words "a" or "an" do not exclude multiple. Furthermore, any element reference numerals in the claims should not be construed as limiting the scope of this disclosure.
