Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bag technology, and in particular to a multi-directional extraction packaging bag. Background Technology
[0002] In the packaging of daily consumer goods, the packaging structure of products such as tissues and wet wipes is usually designed as a single pull-out mode, which only supports front pull-out when laid flat or bottom pull-out when hung.
[0003] Although some improvements address the multi-directional extraction problem by adding independent openings, for example, the utility model patent with authorization announcement number CN220181523 U discloses a packaging bag with a hanging structure at one end, a first tear in the middle of the top surface, and a second tear perpendicular to the first tear at the bottom. When placed horizontally, the tissue can be pulled out upwards from the first tear, and when suspended, the tissue can be pulled out downwards from the second tear, thus meeting the multi-directional extraction requirements.
[0004] However, this design has the following drawbacks. Firstly, the length of the second tear is limited by the rectangular shape of the packaging bag, making it shorter than the width of the top rectangle. This makes it difficult to pull out the tissues, especially when a whole pack of tissues is first used. Because the tissues are tightly packaged and pulled out along the shorter folded direction, it is difficult to pull the tissues out completely from the opening, often resulting in tearing. For non-woven tissues, especially patterned and thicker ones, pulling forcefully can cause the opening to stretch and deform, or the tissues to tear. Secondly, when users switch the packaging bag from a flat tabletop setting to a hanging setting, they need to adjust the direction of pulling out the tissues, causing a disruption in user habits. Also, because it has two tear openings, it is easy to accidentally open the wrong tear opening, thus compromising the airtightness of the packaging bag and causing contamination or waste of the product inside. This problem is particularly prominent in high-humidity environments, such as in a bathroom. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a packaging bag with a single opening but also capable of accommodating multi-directional extraction needs.
[0006] The technical solution of this utility model is:
[0007] A multi-directional extraction packaging bag, characterized in that it includes a bag body, wherein the bag body is provided with a cavity for receiving the extracted item;
[0008] The hanging end is connected to one side of the bag body;
[0009] The tear-off section includes a head, a transition section, and a tail section connected in sequence. The head is close to the hanging end, and the tail is away from the hanging end. The head to the transition section is located on the top surface of the bag body. The length of the tail section perpendicular to the head to the transition section is greater than the width of the head. A receiving gap is provided between the bottom end of the tail section and the transition section.
[0010] Furthermore, the bag body includes four receiving sides connected in sequence, one end of the four receiving sides is connected to a transition side, and the other end of the four receiving sides is connected to a sealing bottom surface.
[0011] The suspension end is connected to the transition side;
[0012] The head to transition section is located on the receiving side in the direction of the top surface of the bag body.
[0013] Furthermore, the width of the head to the transition portion is the same, and it can be any one of a strip shape or a polygonal shape.
[0014] Furthermore, the width of the head gradually increases towards the transition portion.
[0015] Furthermore, the tail is located on the receiving side in the direction of the top surface of the bag body, and the length from the head to the transition portion is greater than the length from the bottom of the tail to the transition portion.
[0016] Furthermore, the tail portion is located on the bottom surface of the package, and the transition portion is located at the bottom edge of the receiving side adjacent to the bottom surface of the package in the direction of the top surface of the bag body.
[0017] Furthermore, the tail portion can be any one of a semi-circular shape, an arc shape, or a sickle-shaped head.
[0018] Furthermore, the ratio of the length of the tail perpendicular to the head to the transition portion to the width of the head is (1.20~1.35):1.
[0019] Furthermore, the bottom surface of the package includes a front package slope and a rear package slope, and a sealing strip is provided at the intersection of the front package slope and the rear package slope, and the sealing strip is located at the central axis of the bottom surface of the package.
[0020] The accommodating gap between the bottom of the tail section and the transition section is located on the front encapsulation slope, and the bottom of the accommodating gap does not intersect with the sealing strip.
[0021] Furthermore, an easily removable dotted line is provided at the intersection of the tear-off portion and the bag body. After the dotted line on the tear-off portion is removed, the head, transition portion and tail portion form a through paper-taking opening.
[0022] The beneficial technical effects of this utility model are:
[0023] In existing technologies, multiple independent paper dispensing openings are usually added to achieve multi-directional paper extraction. However, this also leads to the problem of damaging the sealing of the packaging bag due to accidental paper dispensing. This utility model only has one tear-off part, which can take out the paper towels from the top when the packaging bag is laid flat and from the bottom when the packaging bag is hung up, and also avoids the problem of accidental opening.
[0024] On the other hand, when the tail, head, and transition portion of the tear section are located in the same plane, the length from the head to the transition portion is limited to be greater than the length from the bottom of the tail to the transition portion, and the tail structure has an arc-shaped curve that guides and reduces stress concentration; when the tail, head, and transition portion of the tear section are located in different planes, the ratio of the length of the tail perpendicular to the head to the transition portion to the width of the head is limited to (1.20~1.35):1, which further ensures that the packaging bag always has strong structural support during use, and can also avoid the problem of the paper being torn or the paper taking hole being deformed when taking the paper down from the hanging position, ultimately ensuring the smoothness of taking the paper whether it is laid flat or hanging down.

[0034] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0035] Example 1
[0036] like Figure 1-2 As shown, this embodiment 1 provides a multi-directional extraction packaging bag, which includes a bag body 100. The bag body 100 includes four sequentially connected receiving sides 101. One end of the four receiving sides 101 is connected to a transition side, and the other end of the four receiving sides 101 is connected to a sealing bottom surface. The four receiving sides 101, the transition side, and the sealing bottom surface surround to form a cavity of the bag body 100. For easy horizontal placement, the four receiving sides 101 are uniformly rectangular. For easy hanging of the packaging bag, a hanging end 200 is provided in the middle of the transition side. The hanging end 200 can be a hook, or it can have several hanging holes 201 on its surface. Specifically, in embodiment 1, each hanging end 200 is rectangular, and two hanging holes 201 are provided on the hanging end 200 at intervals from left to right in the center.
[0037] The aforementioned transition sides and the bottom of the package can both be rectangular, or, to increase the stability of the packaging bag when suspended, both the transition sides and the bottom of the package can be designed as "triangular wings," that is, both include two inclined surfaces resembling a "person." Compared to a right-angle design, the inclined surface design will naturally fit the suspension fulcrum and is less prone to swaying. In this embodiment 1, the transition sides and the bottom of the package are illustrated using a "triangular wing" design as an example.
[0038] Specifically, the bottom surface of the packaging includes a front packaging slope 501 and a rear packaging slope 502, and a sealing strip 503 is provided at the intersection of the front packaging slope 501 and the rear packaging slope 502. The sealing strip 503 is located on the central axis of the bottom surface of the packaging and is coaxially arranged with the hanging part 200. After the tissue is placed into the cavity of the bag body 100, the sealing strip 503 is sealed, and the cavity of the bag body 100 becomes a sealed cavity. In order to enable the tissue to be continuously pulled out, several tissues are folded in a Z-shape, and two tissues on the left and right are stacked crosswise in the cavity of the bag body 100. Correspondingly, the length of the receiving side 101 on the top and bottom surfaces of the bag body 100 corresponds to the length of the folded tissue, the width of the receiving side 101 on the top and bottom surfaces of the bag body 100 corresponds to the width of the folded tissue, the receiving side 101 on the top surface of the bag body 100 is on the same side as the front sealing slope 501, and the receiving side 101 on the bottom surface of the bag body 100 is on the same side as the rear sealing slope 502.
[0039] It should be noted that in this utility model, the extractable material is illustrated using paper towels as an example. In practical applications, the extractable material can also be wet wipes, disposable towels, etc.
[0040] A tear-opening portion 300 is provided on the receiving side 101 facing the top surface of the bag body 100. Whether the packaging bag is placed horizontally or suspended, the tissue paper is removed from the tear-opening portion 300. The intersections of the tear-opening portion 300 with the receiving side 101 and the bottom surface of the packaging are all provided with easily removable dotted lines; removing the dotted lines forms the paper dispensing opening.
[0041] The tear-opening portion 300 includes a head 301, a transition portion 302, and a tail 303 connected in sequence. The head 301 is close to the hanging end 200, and the tail 303 is disposed away from the hanging end 200. The head 301 is located on the receiving side 101 in the top direction of the bag body 100, and the transition portion 302 is located at the bottom edge of the receiving side 101 in the top direction of the bag body 100, adjacent to the bottom surface of the packaging.
[0042] To ensure that the paper can still be taken out from the same tear-off part while the packaging bag is in a hanging state, thus avoiding the problem of setting up a separate opening, the tail 303 extends from the receiving side 101 in the direction of the top surface of the bag body 100 to the bottom surface of the packaging; preferably, the tail 303 extends from the receiving side 101 in the direction of the top surface of the bag body 100 to the front packaging slope 501.
[0043] The head 301, transition section 302 and tail section 303 are coaxially arranged. When the dotted tangent line on the tear section 300 is pulled off, the head 301, transition section 302 and tail section 303 form a through paper feeding port.
[0044] Furthermore, in Embodiment 1, the widths of the head 301 to the transition portion 302 are the same, and the length of the tail 303 perpendicular to the direction from the head 301 to the transition portion 302 is greater than the width of the head 301. That is, the length of the tail 303 in the direction parallel to the width of the receiving side 101 in the top direction is greater than the width of the head 301, and a receiving gap is provided between the bottom end of the tail 303 and the transition portion 302.
[0045] When the packaging bag is placed horizontally, the tissues are concentrated on the receiving side 101. When the user pulls the tissues outward from the tear-out part 300, they apply upward or diagonally upward force. The tissues are mainly pulled out from the distance between the head 301 and the transition part 302. The specific length between the head 301 and the transition part 302 can be set according to the requirement that the tissues can be pulled out smoothly. Furthermore, in practical applications, the shape between the head 301 and the transition part 302 can be a strip of equal width at the top and bottom, a rectangle, or a polygonal irregular shape such as a serrated or lace shape.
[0046] When the packaging bag is suspended, the user first grabs or pulls a corner of the tissue between the transition section 302 and the tail section 303, and applies downward or diagonal downward force. The corner of the tissue is first pulled out from the tail section 303, and then the other part of the tissue is pulled out from the transition section 302 to the head section 301. Finally, the entire tissue is pulled out downward or diagonally downward. During this process, on the one hand, the bottom surface of the package is subjected to greater force due to gravity; on the other hand, when the user pulls the tissue out from the tear-off part 300, the force is downward or diagonally downward, causing the tissue to accumulate at the bottom and affecting the smooth extraction of the tissue. To solve this problem, this utility model increases the width of the tail 303. When the user pulls out a corner or part of the tissue from the transition part 302 to the tail 303 and pulls it downward or diagonally downward, the larger width of the tail 303 results in a larger paper outlet area, which can effectively release the squeezing force. Then, under the synergistic effect of the paper outlet gap between the head 301 and the transition part 302, the tissue squeezed on the bottom surface can be pulled out smoothly and instantly, and then completely extracted.
[0047] Furthermore, as can be seen from the above, the larger the width of the head 301 and the width of the transition portion 302, the longer the length of the receiving side 101 parallel to the top surface of the tail 303, and the shorter the length from the bottom of the receiving gap to the sealing strip 503 (i.e., the longer the length from the bottom of the tail 303 to the transition portion 302), the more advantageous it is for the paper towel to be pulled out from below or diagonally below when the packaging bag is hung.
[0048] However, tissue packaging bags are usually made of flexible packaging materials. On the one hand, the packaging bag needs to apply appropriate clamping force to the tissues inside, allowing for continuous extraction. On the other hand, as the tissues in the bag decrease, the flexible packaging bag will deform due to incomplete filling, reducing its support for the contents. The tissues will also deform due to gravity inside the bag. When pulling out the last few tissues, it is easy to pull out all the tissues at once. The larger the opening, the more obvious the deformation of the packaging bag. In addition, if the head is 301 width... The wider the transition section 302 and the longer the width of the receiving side 101 of the tail 303 parallel to the top surface, the easier it is for the tissues inside the bag to be contaminated. Therefore, the width between the head 301 and the transition section 302 should be able to accommodate a single tissue or other single items that can be pulled out smoothly, or slightly larger than this width. The ratio of the length of the receiving side 101 of the bottom 303 parallel to the top surface to the width of the head 301 should be 1.20 to 1.35:1, and more preferably 1.30 to 1.1.
[0049] The length from the bottom of the gap to the sealing strip 503 should be 10-5mm. This ensures that the packaging bag has strong structural support during use and avoids the paper being torn or the paper opening being deformed when the paper is taken down from the hanging position. Ultimately, this ensures smooth paper taking whether the paper is laid flat or suspended downwards.
[0050] Specifically, in embodiment 1, the shape between the head 301 and the transition part 302 is a narrow rectangle, and the tail 303 is a teardrop shape. The teardrop shape has an arc edge design, which helps to reduce stress concentration and further prevents the paper-taking opening from cracking on both sides when the paper is pulled down from the hanging position.
[0051] Example 2
[0052] like Figures 3-4 As shown, this embodiment 2 provides another multi-directional extraction packaging bag. The difference between embodiment 2 and embodiment 1 is that the width of the head 301 to the transition part 302 gradually widens.
[0053] Compared to the same width between the head 301 and the transition portion 302 in Embodiment 1, the gradually increasing width between the head 301 and the transition portion 302 in Embodiment 2 is more conducive to the convenience of hanging and pulling paper downwards and the smoothness of removing the dotted tangent line from the head to the tail.
[0054] Example 3
[0055] like Figure 5 As shown, this embodiment 3 provides another multi-directional extraction packaging bag. The difference between embodiment 3 and embodiment 1 is that the tail and head and the transition are the same, located on the receiving side 101 in the direction of the top surface of the bag body 100, and the length from the head 301 to the transition 302 is greater than the length from the bottom of the tail 303 to the transition 302.
[0056] In Example 3, the tail is semi-circular, and the curved surface of the semi-circular part is located close to the transition part 302.
[0057] As a preferred embodiment, in Example 3, the bottom end of the tail is located at the bottom edge of the receiving side 101 in the direction of the top surface of the bag body 100.
[0058] In addition, the length of the tail in Embodiment 3, perpendicular to the head 301 to the transition portion 302, is larger than the width of the tail in Embodiment 1. It is 1 / 2 to 2 / 3 of the width of the receiving side 101 in the direction of the top surface of the bag body 100, so as to facilitate the downward extraction of paper towels when the packaging bag is hanging.
[0059] Example 4
[0060] like Figure 6As shown, this embodiment 4 provides another type of multi-directional extraction packaging bag. The difference between embodiment 4 and embodiment 3 is that:
[0061] Its tail is sickle-shaped, meaning it has an upper arc surface and a lower arc surface, and the arc-shaped opening faces the transition part 302.
[0062] Example 5
[0063] like Figure 7 As shown, this embodiment 5 provides another multi-directional extraction packaging bag. The difference between embodiment 5 and embodiment 4 is that the width of the head 301 to the transition portion 302 gradually widens.
[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
