Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a three-dimensional bag. Background Technology

[0002] Stand-up pouches, as a common packaging container, are widely used in retail, food, and apparel industries. Their structure typically includes a pair of front panels, a pair of side panels, and a bottom panel. The bottom panel is located below the front and side panels, and the multiple panels connect to form an open cavity. Objects can be placed inside the pouch through the opening for storage or transportation. For ease of carrying, a handle is provided at the opening. The strength of the handle's connection to the pouch body directly determines the stand-up pouch's load-bearing capacity. A high-strength connection ensures that the stand-up pouch is not easily broken or detached when loaded with heavy objects, thus meeting the needs of various usage scenarios.

[0003] However, the opening of a stand-up pouch is formed directly from the top of the side wall of the bag body. It is made of the same material as the side wall of the bag body and opens outward. Since objects enter and exit through this opening, the opening of the pouch is a part that is very easily worn. In the process of frequent wear and tear, the connection strength between the handle and the bag body may be affected. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem in the prior art that the opening of a three-dimensional bag is a part that is easily worn, and that frequent wear may affect the connection strength between the handle and the bag body.

[0005] The present invention discloses a three-dimensional bag, which includes a bag body having a cavity and a handle disposed at the opening of the bag body.

[0006] The bag body has a handle perforation on the side wall near the bag opening, corresponding to the end of the handle. The end of the handle passes through the handle perforation from one side of the bag body and extends to the other side, connecting with the other side surface of the bag body.

[0007] Furthermore, in the height direction of the bag body, a connection area is formed between the handle perforation and the upper edge of the side wall of the bag body, and the connection area has a predetermined height in the height direction, with the ratio of the predetermined height to the height of the bag body in the range of 1:6 to 12.

[0008] In this embodiment, a handle perforation is formed on the side wall of this three-dimensional bag, and the end of the handle penetrates through the side wall of the bag body to form an "embedded" connection. Compared with the traditional handle that is only connected to the bag body by surface stitching or heat-pressing, this nested connection method can disperse some of the stress between the end of the handle and the connection part of the side wall of the bag body, reduce the risk of tearing between the end of the handle and the connection part of the side wall, and improve the connection strength between the bag body and the handle.

[0009] Furthermore, a connection area is formed between the handle perforation and the upper edge of the side wall of the bag body. This connection area has a predetermined height in the vertical direction. On the one hand, it moves the connection between the handle and the bag body downward from the easily worn edge of the bag opening, avoiding frequent friction that weakens the connection strength between the side wall and the end of the handle, thus improving the connection stability between the handle and the bag body. This ensures the normal use of the stand-up pouch and the safe loading of items. Users do not need to worry about the handle breaking at the connection point with the bag body when using this stand-up pouch, and can load and carry items with greater confidence. This safe and reliable feature increases users' trust in the stand-up pouch. On the other hand, the connection area can be used to install accessories for closing the bag opening, head clips to strengthen the edge of the bag opening, or decorative parts, allowing the stand-up pouch to meet more customers' customization needs and expanding its applicability.

[0010] Furthermore, the ratio of the predetermined height of the connecting area to the height of the bag body should be within the range of 1:6 to 12. This ensures that the connection between the handle and the side wall is less prone to wear while allowing the internal cavity of the bag to hold a suitable amount of items. If the ratio of the predetermined height of the connecting area to the height of the bag body is greater than 1:6 (e.g., 1:5), the predetermined height of the connecting area is too high. When the stand-up pouch is full of items, the connecting area is located above the handle perforation and cannot be secured by the handle. During transportation, the side wall located in the connecting area may loosen outward under the pressure of the items, causing the items in the connecting area within the internal cavity to spill out, thus greatly reducing the loading capacity of the stand-up pouch. If the ratio of the predetermined height of the connecting area to the height of the bag body is greater than 1:12 (e.g., 1:15), the predetermined height of the connecting area is too low and cannot effectively reduce friction at the end of the handle and the connection point with the side wall.

[0011] Furthermore, an embodiment of this utility model also discloses a three-dimensional bag, which further includes a bag opening connector disposed within the connection area.

[0012] Specifically, the bag opening connector is a buckle that is located in the connection area of ​​the side walls on opposite sides of the bag body.

[0013] In this embodiment, after the three-dimensional bag is filled with objects, the bag opening can be closed by the bag opening connector to improve the bag opening seal and prevent the items from falling out.

[0014] Specifically, the side walls on both sides of the connecting area are close to and fit together, and the corresponding buckles on the side walls are snapped together to close the bag opening. Even under slight shaking, the bag will not easily open due to the snapping of the buckles.

[0015] Furthermore, an embodiment of this utility model also discloses a three-dimensional bag, which includes an end cap disposed at the top of one side wall of the bag body, the end cap extending toward the other side of the bag body to close the bag opening.

[0016] One end of the end cap is connected to the top of one side wall, and the other end has an adhesive portion that can be connected to the connecting area of ​​the other side wall.

[0017] The end cap can be bent toward the connection area of ​​the other side wall, and the adhesive part is bonded to the outer wall surface of the other side wall to close the bag opening.

[0018] In this embodiment, the three-dimensional bag has an end cap at the top of one side wall of the bag body. The end cap has an adhesive part. The end cap can be bent toward the connection area of ​​the other side wall and is bonded to the outer wall surface of the other side wall through the adhesive part, thereby closing the bag opening. Using the end cap to close the bag opening can make the three-dimensional bag have better sealing performance.

[0019] Furthermore, an embodiment of this utility model also discloses a three-dimensional bag, wherein the predetermined height of the connecting area in the height direction is in the range of 15 mm to 50 mm.

[0020] In this embodiment, the predetermined height of the connecting area in the vertical direction is within the range of 15 mm to 50 mm. On the one hand, this can provide an installation position for the bag opening connector, or ensure that the side wall of the connecting area has sufficient space to connect with the adhesive part of the end cap when the bag opening is closed; on the other hand, it avoids the side wall from becoming loose after the connecting area is filled with items because it is too high.

[0035] As the background art points out, in the prior art, stand-up pouches typically have handles at the opening for easy carrying. However, the opening is frequently worn when taking things out, potentially affecting the connection strength between the handle and the pouch body. To address this, the present invention provides a stand-up pouch with a handle perforation formed on the side wall of the pouch body near the opening, corresponding to the end of the handle. The end of the handle extends from one side of the side wall through the handle perforation to the other side, connecting to the other side surface of the side wall. Furthermore, a connection area is formed between the handle perforation and the upper edge of the side wall in the height direction of the pouch body. This connection area has a predetermined height, with the ratio of the predetermined height to the height of the pouch body ranging from 1:6 to 12. On one hand, by moving the handle-to-pouch connection point downwards from the easily worn edge of the opening, the connection stability between the handle and the pouch body is improved, ensuring the normal use of the stand-up pouch and the safe loading of items. On the other hand, the connection area can be used to install accessories for closing the pouch opening, head clips to strengthen the edge of the opening, or decorative parts.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, this utility model discloses a three-dimensional bag 10, which solves the technical problem that the bag opening is easily worn, thus affecting the connection strength between the handle and the bag body. Specifically, this three-dimensional bag 10 includes a bag body 100 with a cavity and a handle 200 disposed at the opening of the bag body 100. It should be noted that the bag body 100 includes a bottom surface 101 and a pair of front surfaces 102 and a pair of side surfaces 103 connected to the bottom surface 101. Each front surface 102 has side facets 104 on both sides in the length direction. The side facets 104 located on the same side in the width direction are bent and overlapped towards each other to form the side surface 103 of the bag body 100. The side surface 103 is connected to the bottom surface 101 through the bottom surface 101 connecting part. Thus, the pair of front surfaces 102, the pair of side surfaces 103 and the bottom surface 101 at the bottom surround and form an open receiving cavity. Handles 200 can be connected to both of the pair of front surfaces 102. Of course, this embodiment does not limit the specific structure of the bag body 100.

[0038] In this embodiment, a handle perforation 110 is formed on the side wall of the bag body 100 near the bag opening, corresponding to the end of the handle 200. The end of the handle 200 extends from one side of the side wall of the bag body 100 through the handle perforation 110 to the other side and connects to the other side surface of the side wall of the bag body 100. It should be noted that in this embodiment, the handle 200 is provided on the front 102, that is, the handle perforation 110 is located on the side wall of the front 102. Of course, those skilled in the art can provide the handle 200 on the side 103 according to the actual situation and specific needs, or provide handles 200 on both a pair of front 102 and a pair of side 103. This embodiment does not limit this to a single type.

[0039] Furthermore, the end of the handle 200 can be fixedly connected to the corresponding surface of the side wall, that is, as... Figure 1 As shown, the end of the handle 200 can pass through the handle perforation 110 from the outside of the bag body 100 and extend to the inside, and connect with the inner surface of the side wall of the bag body 100. Of course, the end of the handle 200 can also pass through the handle perforation 110 from the inside of the bag body 100 and extend to the outside, and connect with the outer surface of the side wall of the bag body 100.

[0040] Regarding the connection method between the handle 200 and the bag body 100, in one embodiment, both the bag body 100 and the handle 200 are made of non-woven fabric, and the side wall is heat-sealed to the end of the handle 200. Alternatively, the bag body 100 and the handle 200 are made of paper, and the side wall is glued to the end of the handle 200. This utility model does not make specific limitations in this regard.

[0041] In this embodiment, a handle perforation 110 is formed on the side wall of the three-dimensional bag 10. The end of the handle 200 penetrates the side wall of the bag body 100 to form an "embedded" connection. Compared with the traditional handle 200 which is only connected to the bag body 100 by surface stitching or heat-pressing, this nested connection method can disperse some of the stress between the end of the handle 200 and the connection part of the side wall of the bag body 100, reduce the risk of tearing between the end of the handle 200 and the connection part of the side wall, and improve the connection strength between the bag body 100 and the handle 200.

[0042] Furthermore, in this embodiment, a connecting region 120 is formed between the handle perforation 110 and the upper edge of the side wall of the bag body 100 in the height direction. The connecting region 120 has a predetermined height H1 in the height direction, and the ratio of the predetermined height H1 to the height of the bag body 100 is in the range of 1:6 to 12. Specifically, the ratio of the predetermined height H1 to the height H2 of the bag body 100 can be 1:6, 1:6.5, 1:7, 1:10, 1:12, or other ratios within the above range. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0043] Therefore, a connection area 120 is formed between the handle perforation 110 of the stand-up pouch 10 and the upper edge of the side wall of the bag body 100. The connection area 120 has a predetermined height H1 in the height direction. On the one hand, it moves the connection part between the handle 200 and the bag body 100 from the easily worn edge of the bag opening, avoiding frequent friction that weakens the connection strength between the side wall and the end of the handle 200, improving the connection stability between the handle 200 and the bag body 100, ensuring the normal use of the stand-up pouch 10 and the safe loading of items. When using the stand-up pouch 10, users do not need to worry about the breakage of the connection between the handle 200 and the bag body 100, and can load and carry items with more confidence. This safe and reliable feature increases users' trust in the stand-up pouch 10. On the other hand, the connection area 120 can be used to install accessories for closing the bag opening, head clips to strengthen the edge of the bag opening, or decorative parts, so that the stand-up pouch 10 can meet more customers' customization needs and expand the applicability of the stand-up pouch 10.

[0044] In addition, the ratio of the predetermined height H1 of the connecting area 120 to the height H2 of the bag body 100 is in the range of 1:6 to 12, which ensures that the connection between the handle 200 and the side wall is less worn, while the accommodating cavity inside the bag body 100 can normally hold an appropriate amount of items. If the ratio of the predetermined height H1 of the connecting area 120 to the height H2 of the bag body 100 is greater than 1:6 (e.g., 1:5), the predetermined height H1 of the connecting area 120 is too high. When the stand-up pouch 10 is filled with items, the connecting area 120 is located above the handle perforation 110 and cannot be restrained by the handle 200. During transportation, the side wall of the connecting area 120 may loosen outward under the pressure of the items, causing the items in the cavity located in the connecting area 120 to spill out, thereby greatly reducing the loading capacity of the stand-up pouch 10. If the ratio of the predetermined height H1 of the connecting area 120 to the height H2 of the bag body 100 is greater than 1:12 (e.g., 1:15), the predetermined height H1 of the connecting area 120 is too small and cannot effectively reduce the friction at the connection between the end of the handle 200 and the side wall.

[0045] Furthermore, in this embodiment, the predetermined height H1 of the connecting area 120 in the height direction is in the range of 15 mm to 50 mm. On the one hand, this can provide an installation position for the accessories at the bag opening; on the other hand, it avoids the side wall from becoming loose after the connecting area 120 is filled with items because it is too high.

[0046] Specifically, taking a height H2 of 410 mm for the bag body 100 as an example, the predetermined height H1 of the connecting area 120 in the height direction needs to be in the ratio range of 1:6 to 12 with the height H2 of the bag body 100. Furthermore, the predetermined height H1 of the connecting area 120 in the height direction cannot exceed the range of 15 mm to 50 mm. Therefore, the predetermined height H1 of the connecting area 120 in the height direction can be 35 mm, 40 mm, 48 mm, 50 mm, etc.

[0047] Furthermore, such as Figure 2 As shown, an embodiment of the present invention also discloses a three-dimensional bag 10, which further includes a bag opening connector 121, which is disposed within the connection area 120.

[0048] Specifically, the bag opening connector 121 is a buckle that is provided in the connection area 120 of the side wall on both sides of the bag body 100 and corresponds to each other.

[0049] In this embodiment, after the three-dimensional bag 10 is filled with objects, the bag opening can be closed by the bag opening connector 121 to improve the sealing performance of the bag opening and prevent the items from falling out.

[0050] Specifically, the side walls of the connecting area 120 are close to and fit together on both sides, and the corresponding fasteners on the side walls are engaged with each other, thereby closing the bag opening. Even under slight shaking, the bag body 100 will not easily open due to the engagement and fixation of the fasteners.

[0051] To improve the closure of the bag opening, such as Figure 2 As shown, on each front side 102 of the bag body 100, two fasteners are spaced apart along the width direction. When the bag opening is closed, the side walls of a pair of front sides 102 located in the connecting area 120 are brought close together and then the two pairs of fasteners are engaged with each other. Of course, those skilled in the art can design the specific structure and arrangement of the fasteners according to actual conditions and specific needs, and this embodiment does not impose specific limitations on this.

[0052] Furthermore, such as Figure 3 As shown, an embodiment of the present invention also discloses a three-dimensional bag 10, which includes an end cap 130 disposed at the top of one side wall of the bag body 100, the end cap 130 extending toward the other side of the bag body 100 to close the bag opening.

[0053] One end of the end cap 130 is connected to the top of one side wall, and the other end has an adhesive portion 131 that can be connected to the connection area 120 of the other side wall.

[0054] The end cap 130 can be bent toward the connection area 120 of the other side wall, and the adhesive part 131 is bonded to the outer wall surface of the other side wall to close the bag opening of the bag body 100.

[0055] In this embodiment, the three-dimensional bag 10 has an end cap 130 at the top of one side wall of the bag body 100. The end cap 130 has an adhesive portion 131. The end cap 130 can be bent toward the connection area 120 of the other side wall and is bonded to the outer wall surface of the other side wall through the adhesive portion 131, thereby closing the bag opening. Closing the bag opening with the end cap 130 can make the three-dimensional bag 10 have better sealing performance.

[0056] Specifically, the material of the end cap 130 can be the same as that of the bag body 100. For example, if the bag body 100 is made of non-woven fabric, the end cap 130 can also be made of non-woven fabric. Alternatively, if the bag body 100 is made of paper, the end cap 130 can also be made of paper. The end cap 130 can be integrally formed with the side wall of the corresponding side (front 102) of the bag body 100, or the end cap 130 can be overlapped and fixedly connected to the opposite ends of the corresponding side (front 102) of the bag body 100. For example, if both the end cap 130 and the bag body 100 are made of non-woven fabric, they can be heat-sealed together. Or, if both the end cap 130 and the bag body 100 are made of paper, they can be bonded together with adhesive. It should be noted that the material of the end cap 130 can also be different from that of the bag body 100. For example, if the bag body 100 is made of non-woven fabric, the end cap 130 can be made of paper. This embodiment does not limit this to a single material.

[0057] Furthermore, the adhesive portion 131 of the end cap 130 can be provided with Velcro or double-sided adhesive. Those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not limit it to a single type.

[0058] The following explains the specific method of closing the bag opening using end cap 130.

[0059] like Figure 4 As shown, in one embodiment, the length of the end cap 130 is less than the spacing between a pair of front faces 102, and the adhesive portion 131 is located on the outer surface of the end cap 130 near the bag body 100. When the bag is closed, one sidewall of the bag body 100 is in contact with the other sidewall, that is, the sidewalls of the pair of front faces 102 located in the connecting area 120 are close to each other, the end cap 130 is bent toward the other sidewall, and the adhesive portion 131 is bonded to the outer wall surface of the other sidewall.

[0060] In this embodiment, the unfolded area of ​​the end cap 130 is small, which can reduce the material required for the three-dimensional bag 10 and reduce production costs. However, when closing, the side wall of the bag body 100 located in the connecting area 120 needs to be bent to cooperate with the end cap 130 for closure.

[0061] like Figure 5 As shown, in another embodiment, the length of the end cap 130 is equal to or slightly greater than the spacing between a pair of front faces 102. The adhesive portion 131 is located on the outer surface of the end cap 130 near the bag body 100 and can be bent toward the bag body 100. When the bag opening is closed, one side wall of the bag body 100 and the other side wall are spaced apart and exposed at the bag opening. The end cap 130 is bent toward the other side wall, and the adhesive portion 131 is bent and adhered to the outer wall surface of the other side wall.

[0062] In this embodiment, the unfolded area of ​​the end cap 130 is large, but when closed, there is no need to bend the side wall of the bag body 100 located in the connecting area 120, ensuring that the accommodating cavity of the three-dimensional bag 10 can be fully utilized.

[0063] The following describes the handle perforation 110 on the bag body 100 through which the end of the handle 200 passes.

[0064] like Figure 6 As shown, a handle perforation 110 is provided on the bag body 100 for the end of the handle 200 to pass through. Each handle perforation 110 includes a linearly extending main cut 111. The main cut 111 includes a first extension 112 and two second extensions 113 extending from both sides of the first extension 112 and communicating with the first extension 112. The two second extensions 113 and the first extension 112 are linearly extended and their connection points are smoothly transitioned.

[0065] Furthermore, the extension direction of the first extension 112 is parallel to the upper edge of the bag opening, and each second extension 113 is inclined relative to the extension direction of the first extension 112, and the two second extensions 113 extend in directions opposite to each other.

[0066] In this embodiment, the main cut 111 can be opened along the second extensions 113 on both sides, thereby lifting the sheet material forming a trapezoidal area enclosed by the first extension 112, the two second extensions 113, and the line connecting the ends of the two second extensions 113. This makes it easier for the handle 200 and the components that hold the handle 200 (such as hooks or grippers) or the hand holding the handle 200 to pass through. Furthermore, the smooth transition at the connection points between the two second extensions 113 and the first extension 112 further reduces stress concentration, helps to distribute stress during the assembly of the handle 200, and reduces the risk of tearing at the cut.

[0067] Furthermore, such as Figure 6 As shown, each of the two second extensions 113 has a linearly extending auxiliary cut 114 formed at its opposite endpoints. Each auxiliary cut 114 extends from its corresponding endpoint along a direction that bends and intersects with the extension direction of the corresponding second extension 113 at that endpoint, and the two auxiliary cuts 114 extend in opposite directions.

[0068] In this embodiment, when the through hole is opened along the extension direction of the main cut 111, the shearing force acting on the endpoint of the main cut 111 is along the extension direction of the second extension 113 at that endpoint. The auxiliary cuts 114 provided at both ends of the main cut 111 have different extension directions than the second extension 113 at that endpoint. Therefore, the shearing force borne by the auxiliary cuts 114 is only a component of the shearing force on the main cut 111, greatly reducing the risk of the auxiliary cuts 114 being torn. Furthermore, since the auxiliary cuts 114 are bent and intersected at the ends of the main cut 111, forming inflection points at both ends of the main cut 111, even if the handle 200 is assembled inside the main cut 111, it will not easily shift towards the auxiliary cuts 114.

[0069] Compared to existing technologies that use double-layer structures or corrugated paper to increase support, reinforce the cut with tape or fabric, or use tear-resistant materials or fabric linings to reinforce the cut, the stand-up pouch 10 provided in this embodiment does not require additional reinforcing structures or changes to local materials. It can effectively reduce the risk of tearing of the main cut 111 connecting the handle 200 through the auxiliary cut 114. This not only improves the yield of the stand-up pouch 10, but also ensures the assembly stability between the handle 200 and the bag body 100.

[0070] More specifically, such as Figure 6 As shown, in this embodiment, the extension direction of each auxiliary cut 114 intersects the extension direction of the second extension 113 on the corresponding side at an acute angle at that end point; and when viewed along a direction perpendicular to the sidewall, each auxiliary cut 114 and the second extension 113 on the corresponding side form a "V" shape with an acute interior angle.

[0071] In another embodiment, the extension direction of each auxiliary cut 114 is parallel to the extension direction of the first extension 112, and the extension direction of each auxiliary cut 114 intersects the extension direction of the second extension 113 on the corresponding side at an obtuse angle at that end point; and when viewed along a direction perpendicular to the sidewall, each auxiliary cut 114 and the second extension 113 on the corresponding side form a "V" shape with an obtuse interior angle.

[0072] In another embodiment, the extension direction of each auxiliary cut 114 intersects the extension direction of the second extension 113 on the corresponding side at an obtuse angle at that end point; and when viewed along a direction perpendicular to the sidewall, the extension lines of each auxiliary cut 114 and the second extension 113 on the corresponding side at that end point form a “V” shape with an acute interior angle.

[0073] Of course, this embodiment does not limit the specific structure and arrangement of the handle perforation 110. Those skilled in the art can design it according to actual conditions and specific needs.
