Abstract
Description
Technical Field
[0001] The present disclosure generally relates to the field of packaging technology, and more particularly, to a packaging bag suitable for containing contents such as laundry detergent and a laundry detergent packaging product. Background Art
[0002] Laundry detergent is usually sold in a flexible packaging bag made of at least one waterproof or water-resistant flexible film. Taking granular laundry detergent as an example, when a consumer is ready to use granular laundry detergent, he / she will tear or cut an opening at the top corner of the flexible packaging bag, and the granular laundry detergent can be poured out through the opening. After each use, such openings will need to be closed, for example, with a clip or rubber band, to prevent the granular laundry detergent from leaking out of the packaging bag, while preventing moisture / water from entering the packaging bag and causing the granular laundry detergent to clump or aggregate inside. However, the size and shape of such openings formed by tearing or cutting may vary greatly, making it difficult to control the amount and speed of the granular laundry detergent dispensed from such openings. In addition, closing such openings with a clip or rubber band may still cause accidental leakage, and they may not form an effective moisture / waterproof barrier.
[0003] In recent years, more and more flexible packaging bags with spouts, i.e., flexible packaging bags with spouts located at the top or upper corners thereof, are used to easily dispense and better enclose granular laundry detergents. In real life, consumers prefer to purchase granular laundry detergent products with large-capacity flexible packaging bags. Even for flexible packaging bags with spouts, each time they are used, due to the large weight of the large-capacity flexible packaging bags, consumers cannot stably hold the packaging bag during the process of pouring the granular laundry detergent through the spout, and it is also difficult to control the amount and speed of the granular laundry detergent dispensed from the spout.
[0004] In addition, for granular laundry detergent products with flexible packaging bags, consumers need to lift the flexible packaging bag and keep the flexible packaging bag in a certain tilted posture for a period of time each time they use it, so as to dispense a certain amount of granular laundry detergent from the opening / mouth of the flexible packaging bag. The flexible characteristics of the packaging bag not only make it difficult to effectively control the amount and speed of the granular laundry detergent dispensed from the opening / mouth, but also make it difficult to effectively maintain the tilted posture of the packaging bag during dispensing, or require a certain amount of attention and physical strength to maintain the tilted posture of the packaging bag, which causes inconvenience and fatigue to consumers during use, thereby resulting in a poor user experience.

[0033] According to this disclosure, see Figures 1 to 3 , a packaging bag 100 is provided. The packaging bag 100 mainly includes: a flexible bag body 10, a rigid mouth 20, and a handle 30. The mouth 20 and the handle 30 are both arranged on the upper part of the flexible bag body 10. The mouth 20 is configured to dispense the contents (granular laundry detergent in an exemplary embodiment) contained in the flexible bag body 10 through the mouth 20. The handle 30 is configured to dispense the contents through the mouth 20 in a stable and controllable manner when the user lifts the packaging bag 1 by the handle 30. According to the present disclosure, as Figure 1As shown, the mouth 20 defines a mouth axis A1, and the handle 30 defines a handle axis A2. An angle c is formed between the handle axis A2 and a plane P perpendicular to the mouth axis A1, and the angle c is less than 120 degrees.
[0034] As used herein, the term "spout axis" may refer to the central axis along which the main dispensing passage of the spout is located, and generally, the spout axis is substantially perpendicular to the plane in which the spout outlet is located. The term "handle axis" may refer to the line between the two farthest points of the handle, for example, the axis along which the long side of the handle is located if the handle has a relatively regular shape.
[0035] Herein, the term "flexible" may refer to a packaging material that is easily deformable and cannot maintain a fixed shape or stand independently at room temperature and atmospheric pressure by virtue of its material properties (e.g., hardness). The term "rigid" may refer to a material that is not easily deformed and can maintain a fixed shape or stand independently at room temperature and atmospheric pressure by virtue of its material properties (e.g., hardness).
[0036] As used herein, the term "granular laundry detergent" may refer to a solid powdered or granular laundry detergent, preferably a free-flowing powdered or granular laundry detergent, such as an all-purpose detergent or a heavy-duty detergent for fabrics, and a laundry detergent adjuvant such as a bleach active, rinse aid, additive or pre-treatment product.
[0037] Figure 1 The figure is a simplified schematic diagram of the structure of a packaging bag according to the present invention. Figure 2 and Figure 3 They are schematic diagrams of the front and bottom structures of a packaging bag according to an exemplary embodiment of the present disclosure. It should be noted that, for the sake of clarity, dashed lines are used in the figure to represent axes (for example, including but not limited to the mouth axis A1 and the handle axis A2), orientation reference lines (for example, including but not limited to the horizontal reference line H and the vertical reference line perpendicular to the horizontal reference line), and other auxiliary lines (for example, including but not limited to the plane P perpendicular to the mouth axis A1), etc.
[0038] Specifically, Figures 1 to 3As shown, according to an exemplary embodiment of the present disclosure, in a packaging bag 100, a flexible bag body 10 has a bottom edge 11, a top edge 12 opposite to the bottom edge 11, and opposite first side edges 13 and second side edges 14 extending between the top edge 12 and the bottom edge 11. As shown in the figure, the mouth 20 is arranged at the corner of the top edge 12 close to the first side edge 13, and the mouth axis A1 of the mouth 20 forms a first inclination angle a relative to the bottom edge 11 of the flexible bag body 10 (or relative to the horizontal reference line H parallel to the bottom edge 11). The handle 30 is arranged at the corner of the top edge 12 close to the second side edge 14, and the handle axis A2 of the handle 30 forms a second inclination angle b relative to the bottom edge 11 of the flexible bag body 10 (or relative to the horizontal reference line parallel to the bottom edge 11). The angle c between the handle axis A2 and the plane P perpendicular to the mouth axis A1 is equivalent to the sum of the first inclination angle a and the second inclination angle b, that is, c=a+b.
[0039] It should be noted that, in the illustrated embodiment, the various edges of the flexible bag body 10 (including but not limited to the bottom edge 11, the top edge 12, the first side edge 13 and the second side edge 14, and the first oblique edge 15 and the second oblique edge 16 to be mentioned below) have a basically linear shape, but the present disclosure is not limited to this. For example, these edges may also have other shapes (such as a corrugated shape or a zigzag shape, etc.).
[0040] According to the present disclosure, the first inclination angle a is in the range of 0 to 90 degrees, and the second inclination angle b is in the range of 0 to 90 degrees. Preferably, the first inclination angle a is in the range of 15 to 75 degrees, and the second inclination angle b is in the range of 5 to 85 degrees. More preferably, the first inclination angle a is in the range of 30 to 45 degrees, and the second inclination angle b is in the range of 15 to 75 degrees. According to an exemplary embodiment, the first inclination angle a can be 30 degrees, and the second inclination angle b can be 30 degrees. In this case, the angle c between the handle axis A2 and the plane P perpendicular to the mouth axis A1 can be 60 degrees. Of course, in some embodiments, the first inclination angle a can be substantially 0 degrees (that is, the mouth axis A1 of the mouth 20 is substantially parallel to the bottom edge 11 of the flexible bag body 10), and at this time, the mouth 20 is arranged at the first side 13. In other embodiments, the first inclination angle a may be substantially 90 degrees (i.e., the mouth axis A1 of the mouth 20 is substantially perpendicular to the bottom edge 11 of the flexible bag body 10), in which case the mouth 20 may be disposed at the top edge 12. Meanwhile, in some embodiments, the second inclination angle b may be substantially 0 degrees, in which case the handle axis A2 of the handle 30 is disposed substantially parallel to the bottom edge 11 of the flexible bag body 10. In other embodiments, the second inclination angle b may be substantially 90 degrees, in which case the handle axis A2 of the handle 30 is disposed substantially perpendicular to the bottom edge 11 of the flexible bag body 10.
[0041] Table 1 shows the test data obtained when the first inclination angle a of the mouth 20 is set to different values within the range of 0 to 90 degrees, assuming that the second inclination angle b of the handle 30 is set to 30 degrees. During the test, when the packaging bag 100 is rotated 90 degrees and hovered for 3 seconds, three groups of dispensing amounts of the contents dispensed from the mouth 20 of the packaging bag 100 and their average dispensing amounts are shown. In the table, the unit of the column where "the range of values of the first inclination angle a of the mouth" is degree (°), and the unit of the columns where "average dispensing amount" and "dispensing amount" are grams (g).
[0042]
[0043] Table 1
[0044] It can be concluded from Table 1 that, under the premise that the second inclination angle b of the handle 30 is 30 degrees, when the first inclination angle a of the mouth 20 is in the range of 7.5 degrees to 60 degrees (preferably in the range of 15 degrees to 60 degrees), a relatively ideal dispensing amount can be obtained. Accordingly, based on c=a+b, the angle c is in the range of 37.5 degrees to 90 degrees (especially in the range of 45 degrees to 60 degrees).
[0045] In some alternative embodiments, the handle 30 is designed so that the handle axis A2 thereof may be substantially parallel to the top edge 12 of the flexible bag body 10 , and the handle 30 is disposed near the top edge 12 and located approximately in the middle of the top edge 12 .
[0046] According to the present disclosure, in the packaging bag 100, the mouth 20 is disposed at a position where the top edge 12 of the flexible bag body 10 is close to the first side edge 13. The handle 30 is disposed at a position where the top edge 12 of the flexible bag body 10 is close to the second side edge 14. Figures 1 to 3 In the exemplary embodiment shown, the top edge 12 of the flexible bag body 10 is connected to the first side edge 13 via the first bevel 15, and the mouth 20 is attached to the first bevel 15. Preferably, the mouth axis A1 of the mouth 20 may be perpendicular to the first bevel 15. At the same time, the top edge 12 of the flexible bag body 10 is connected to the second side edge 14 via the second bevel 16, and the handle 30 is formed near the second bevel 16. Preferably, the handle axis A2 of the handle 30 may be parallel to the second bevel 16. Of course, in other embodiments, the flexible bag body 10 may also not have the first bevel and the second bevel. In this case, the mouth 20 may be directly formed at the corner between the top edge 12 and the first side edge 13, and the handle 30 may be formed near the corner between the top edge 12 and the second side edge 14, as long as the angle between the mouth 20 and the handle 30 is not affected.
[0047] It can be seen that according to the present disclosure, by respectively arranging a mouth 20 and a handle 30 on the upper part of the flexible bag body 10, and adopting a suitable angle range design between the mouth 20 and the handle 30 (for example, the angle c between the handle axis A2 and the plane P perpendicular to the mouth axis A1 is less than 120 degrees, preferably in the range of 60 to 90 degrees), it is possible to achieve easy and controllable distribution of the contents contained in the packaging bag, so as to form a stable and continuous flow of the contents at an appropriate flow rate during the distribution process.
[0048] More specifically, according to the embodiments of the present disclosure, Figures 1 to 3 As shown, the flexible bag body 10 includes at least a first sheet 10a and a second sheet 10b, and the first sheet 10a and the second sheet 10a can be of the same shape. The first sheet 10a and the second sheet 10a are combined together at least at the bottom edge 11, the first side edge 13 and the second side edge 14 to form a storage space for the flexible bag body 10 therebetween. Further, in some embodiments, the flexible bag body 10 may also include an insert bottom 10c. The flexible bag body 10 can be self-supporting by inserting the bottom 10c. Specifically, the first sheet 10a and the second sheet 10b are combined together at least at the first side edge 13 and the second side edge 14, and the first sheet 10a, the second sheet 10b and the insert bottom 10c are combined together at the bottom edge 11 to form a storage space for the flexible bag body 10 therebetween, wherein the insert bottom 10c can be folded in half and sandwiched between the first sheet 10a and the second sheet 10a. According to an exemplary embodiment of the present disclosure, the flexible bag body 10 is composed of a first sheet 10a, a second sheet 10b and an insert 10c. In some other embodiments not shown, the flexible bag body 10 may also be composed of only the first sheet 10a and the second sheet 10b, that is, without an insert.
[0049] According to the present disclosure, the first sheet and / or the second sheet and / or the insert bottom of the flexible bag body 10 can be formed by at least one flexible film material, and the flexibility coefficient (elastic modulus) of the flexible film material is 100Mpa (N / mm 2 ) to 1500Mpa(N / mm 2 ), preferably within the range of 400Mpa (N / mm 2 ) to 1100Mpa(N / mm 2 ); the thickness of the flexible film material is in the range of 20micron to 250micron, preferably in the range of 100micron to 160micron.
[0050] According to the present disclosure, the first sheet and / or the second sheet and / or the insert bottom of the flexible bag body can be made of a multi-layer or double-layer composite film. The inner layer is in contact with the laundry detergent contained in the flexible bag body, and the outer layer forms the outermost surface of the flexible bag body. For example, in an embodiment using a multi-layer composite film, the outer layer is preferably polyester, the inner layer is preferably polyethylene, and the middle layer is preferably nylon. In another embodiment using a multi-layer composite film, the outer layer is preferably uniaxially stretched polyethylene, the inner layer is preferably low-density polyethylene, and the middle layer is preferably biaxially stretched polyethylene material. In an embodiment using a double-layer composite film, the outer layer is preferably polyester, and the inner layer is preferably polyethylene. In an embodiment using a double-layer composite film, the outer layer is preferably nylon, and the inner layer is preferably polyethylene. Of course, the composite film can also be made of recyclable / renewable materials of the above-mentioned materials. Of course, in other embodiments, the first sheet and / or the second sheet and / or the insert bottom of the flexible bag body can also be made of any suitable flexible film and / or composite film material according to actual needs, and the present disclosure is not limited here.
[0051] In addition, a portion, multiple portions, or all of the first sheet and / or second sheet and / or insert of the flexible bag body 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 material used to make the flexible bag body disclosed herein may be formed in any manner known in the art and may be joined together using any type of joining or sealing method known in the art, including, for example, heat sealing (e.g., conductive sealing, impulse sealing, ultrasonic sealing, etc.), welding, crimping, bonding, adhering, etc., and any combination of these.
[0052] More specifically, according to the embodiments of the present disclosure, Figures 1 to 3As shown, the rigid mouth 20 includes a mouth body. The mouth body is cylindrical, and defines a cylindrical distribution channel therein. The mouth body of the mouth 20 is communicated with the internal accommodation space of the flexible bag body 10, and is configured to distribute granular laundry detergent from the internal accommodation space of the flexible bag body 10. The diameter of the mouth body is in the range of 20mm to 50mm, preferably, the opening diameter of the mouth body is in the range of 20mm to 30mm, more preferably in the range of 21mm to 28mm, and most preferably in the range of 22mm to 26mm. It is found through testing that the rigid mouth body with an opening diameter in the above range is particularly suitable for distributing granular laundry detergent. If the mouth body opening diameter is lower than 20mm, for example 15mm, the volume flow rate for distributing granular laundry detergent is too slow and may cause insufficient feeding. If the mouth body opening diameter is greater than 30mm, for example 33mm, the volume flow rate for distributing granular laundry detergent is too fast and may cause excessive feeding. The height of the nozzle body is in the range of 20 mm to 50 mm, preferably in the range of 30 mm to 40 mm, more preferably in the range of 32 mm to 38 mm.
[0053] According to the present disclosure, the rigid mouth 20 also includes a rigid shoulder. The shoulder is integrally formed with the mouth and is located on both sides of the base of the mouth, and the mouth 20 is attached to the flexible bag body 10 via the shoulder (for example, in the exemplary embodiment shown in the figure, attached to the first bevel 15 of the flexible bag body 10). In an exemplary embodiment, the mouth 20 can be attached between the first sheet 10a and the second sheet 10b of the flexible bag body 10 via the shoulder in a heat-sealed manner. The shoulder is attached along the flexible bag body 10 (for example, in the exemplary embodiment shown in the figure). Figure 2 In the exemplary embodiment shown, the length of the first oblique side 15 of the flexible bag body 10 is in the range of 30 mm to 70 mm. By setting the length of the shoulder in the aforementioned range, while helping to provide structural support near the base of the mouth body, the granular laundry detergent can be dispensed without hindrance and dust can be effectively prevented during the dispensing process.
[0054] According to the present disclosure, the rigid mouth 20 may also include a cover (not shown). The cover removably covers the mouth body. For example, the cover is removably engaged to the mouth body of the rigid mouth 20 via internal threads that engage with corresponding external threads on the mouth body to close the dispensing channel in the mouth body and prevent accidental leakage of granular laundry detergent.
[0055] Compared with the flexible film / composite film of the flexible bag body 10 itself, the mouth body and / or shoulder and / or cover of the mouth 20 as described above have a relatively rigid structure and can be made of any suitable rigid material, such as glass, metal, polymer, etc., but preferably made of polymer. Specifically, the mouth body and / or shoulder and / or cover can be made of the same or different materials. Preferably, each of them is independently made of a group selected from polypropylene (PP), polyethylene (PE), polycarbonate (PC), polyamide (PA), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polystyrene (PS) and combinations thereof.
[0056] Specifically, according to the embodiment of the present disclosure, in the packaging bag 100, the handle 30 can be designed so that there is a certain distance between the top of the handle 30 and the top edge 12 of the flexible bag body 10, and the distance is generally less than 40 mm, preferably 30 mm. Figures 1 to 3 As shown, the handle 30 is generally ear-shaped. The handle 30 may include: a peripheral portion and a through portion defined by the peripheral portion, the through portion penetrating the flexible bag body 10. The peripheral portion is formed with at least two finger-receiving grooves 33 toward the inner periphery of the through portion. The handle 30 may be attached between the first sheet 10a and the second sheet 10b of the flexible bag body 10 in a heat-sealed manner via the outer periphery of the peripheral portion. According to the present disclosure, the handle 30 may be rigid, for example, the handle 30 may be made of a plastic material such as polypropylene or polyethylene, or pulp. In some alternative embodiments, the handle may also be a through hole formed by cutting / piercing one or more sealed portions of the flexible bag body 10 (i.e., a completely open space through which fingers and / or thumbs can be inserted).
[0057] According to the present disclosure, the packaging bag 100 is substantially rectangular in shape except for the first oblique side 15 where the mouth 20 is located and the second oblique side 15 where the handle is located. In a preferred exemplary embodiment, the distance between the bottom side 11 and the top side 12 of the flexible bag body 10 is less than the distance between the first side 13 and the second side 14; that is, when the packaging bag 100 stands, the height of the packaging bag is less than its width. In some alternative embodiments, the distance between the bottom side 11 and the top side 12 of the flexible bag body 10 is greater than the distance between the first side 13 and the second side 14; that is, when the packaging bag 100 stands, the height of the packaging bag is greater than its width. In other alternative embodiments, the distance between the bottom side 11 and the top side 12 of the flexible bag body 10 is equal to the distance between the first side 13 and the second side 14; that is, when the packaging bag 100 stands, the height of the packaging bag is equal to its width.
[0058] According to another aspect of the present disclosure, a laundry detergent packaging product is provided. Specifically, the laundry detergent packaging product includes: a packaging bag 100 as described in any of the above embodiments, and laundry detergent contained in the packaging bag 100 .
[0059] According to the present disclosure, although in the aspects and / or embodiments described above, granular laundry detergent is used as an example of laundry detergent, the laundry detergent mentioned herein may also be a liquid laundry detergent or a softener. In addition, one or more of the following additives may be added to these laundry detergents: surfactants, softeners, foam suppressants, foam enhancers, whitening agents, stain removal additives, etc.
[0060] According to the present disclosure, in embodiments where the laundry detergent is a granular laundry detergent, the particles of the granular laundry detergent may be characterized by a median weight particle size (Dw50) in the range of 200 μm to 1000 μm, preferably in the range of 250 μm to 950 μm, more preferably in the range of 300 μm to 850 μm. The particles of the granular laundry detergent may also be characterized by a bulk density of 0.3 g / cm 3 Up to 0.9g / cm 3 In the range of 0.35 g / cm 3 Up to 0.8g / cm 3 within the range.
[0061] According to the present disclosure, the packaging bag 100 may further include a filling opening (not shown). The filling opening is formed at the top edge 12 of the flexible bag body 10 and is located between the mouth 20 and the handle 30. During the manufacturing process of the packaging bag 100, first, the first sheet 10a, the second sheet 10b and the insert bottom 10c are edge-sealed except for the filling opening located between the mouth 20 and the handle 30; then, laundry detergent is filled into the flexible bag body through the filling opening, and then the filling opening is sealed to form a final laundry detergent packaging product.
[0062] According to another aspect of the present disclosure, in order to improve the user experience of consumers when using packaging bags and / or laundry detergent packaging products and reduce the inconvenience and fatigue of consumers during use, the present disclosure also provides an ergonomic packaging bag design.
