Description
Technical Field
[0001] The utility model belongs to the technical field of plastic packaging bags, in particular to a packaging bag that is anti-strangulation. Background Art
[0002] In recent years, plastic packaging bags have been increasingly adopted by industries such as daily chemicals, food and beverages, and pet food, gradually replacing plastic cans due to their lower costs, environmental friendliness, stable materials, and wide application range. As their use continues to expand, the public is increasingly concerned about the ease of use and comfort of plastic packaging bags.
[0003] Especially for plastic packaging bags that store large volumes of liquid, granular, or powdered products, a handle that facilitates lifting and pouring is currently a common feature of such plastic packaging bags. However, existing plastic packaging bags are provided with openings. When pulling, fingers will feel a strong pinching sensation. In order to avoid the pinching problem and make the plastic bag more comfortable to pull, the market often adopts methods such as adding a soft handle sheet at the handle hole position, surrounding the handle hole with a rubber handle ring, or providing an inflatable structure on the lifting side to avoid pinching. However, when using the above methods to produce plastic packaging bags, it is inevitable that the production cost of the plastic packaging bags will increase and the production efficiency of the plastic packaging bags will decrease. Summary of the Invention
[0004] To address the shortcomings of the prior art, the present invention provides a packaging bag with an anti-strangulation effect. This bag features a handle area surrounded by an unpressed area within the heat-pressed area of the bag body, a handle structure, and a buffering portion. This provides a soft, wide contact area between the fingers and the buffering portion, making it more comfortable to lift the bag without any pinching. The handle area is an unpressed area surrounded by the heat-pressed area, eliminating the pinching effect during lifting without the need for additional components. This simplifies the manufacturing process and reduces costs.
[0005] The technical effects to be achieved by the present invention are specifically achieved through the following technical aspects:
[0006] The utility model provides a hand-strangulation-proof packaging bag, comprising a bag body, wherein the bag body is provided with a first film sheet and a second film sheet, wherein the first film sheet and the second film sheet are hot-pressed together at their edges to form a hot-pressing zone, and a receiving cavity is formed inside the hot-pressing zone;
[0007] The bag body is also provided with a handle area, which is located in the hot pressing area and is a non-hot pressing area surrounded by the hot pressing area; a handle structure is provided on the handle area; a buffer portion is provided between the handle structure and the hot pressing area on the side away from the accommodating cavity.
[0008] In some embodiments, a lifting hole is provided on the handle structure, and the lifting hole is located on a side of the buffer portion facing the accommodating cavity.
[0009] In some embodiments, the handle structure is provided with a lifting ear, which is connected to the buffer portion, and a bending area is formed at the connection. The lifting ear and the buffer portion are bent at the bending area so that the lifting ear can be flipped toward the outside of the bag body.
[0010] In some embodiments, at both ends of the bending region, the lifting ears are respectively provided with lug portions protruding toward the buffer portion.
[0011] In some embodiments, rounded corners are provided on an end of the lug portion protruding toward the buffer portion and an end of the lug portion away from the bending zone.
[0012] In some embodiments, the length of the bending zone is less than or equal to the length of the pulling hole.
[0013] In some embodiments, the ear is formed by cutting the handle area along an unclosed cutting line at the position of the pulling hole, and after the ear is flipped toward the outside of the bag body, the pulling hole is formed at the position of the handle area.
[0014] In some embodiments, a side of the lifting ear facing the accommodating cavity is locally hot-pressed.
[0015] In some embodiments, the lifting hole is arc-shaped on a side facing the accommodating cavity, and both ends of the arc form rounded corners.
[0016] In some embodiments, a connecting piece is provided on a side of the bag body away from the handle area, and the connecting piece connects the accommodating cavity with the outside of the bag body.

[0041] Example 1
[0042] like Figure 1 As shown, this embodiment provides a packaging bag that prevents hand strangulation. It includes a bag body 100 formed by hot pressing of plastic film sheets. The plastic film sheet can be formed by folding a whole long strip of film material and then hot pressing, or by arranging multiple films in a certain pattern and then hot pressing. This embodiment uses two films, namely a first film sheet 1 and a second film sheet 2. Figure 1In the figure, the first diaphragm 1 is the visible diaphragm, and the second diaphragm 2 is the diaphragm obscured by the first diaphragm 1. The edges of the first and second diaphragms 1 and 2 are hot-pressed together to form a hot-pressing zone 3, and a receiving cavity 4 is formed inside the hot-pressing zone 3. Through high-temperature hot pressing, the first and second diaphragms 1 and 2 are hardened and formed integrally in the hot-pressing zone 3, forming a sealed space within the hot-pressing zone 3. The receiving cavity 4 can be used to hold liquids, powders, or granular items, such as laundry detergent, laundry powder, slow-release fertilizer granules, or cat or dog food.
[0043] The bag body 100 is provided with a handle area 5, which is located in the hot pressing area 3. The handle area 5 is an un-hot pressed area surrounded by the hot pressing area 3. The handle area 5 is provided with a handle structure 51, and the handle structure 51 has a buffer portion 511 between the hot pressing area 3 and the side away from the accommodating cavity 4. Compared with the hot pressing area 3, the first membrane 1 and the second membrane 2 in the un-hot pressing area have not been hardened by hot pressing, and the material maintains the characteristics of the membrane being soft and elastic. After the hand passes through the handle structure 51, it comes into soft contact with the buffer portion 511, eliminating the feeling of being squeezed when the hand is pulled by the bag body 100. As the bag body 100 is pulled upward, the soft membrane material of the buffer portion 511 is deformed by force, and the contact area between the hand and the buffer portion 511 gradually increases, further avoiding the feeling of being squeezed.
[0044] Because the handle region 5 is merely an unpressed area surrounded by the hot pressing region 3, it is formed simultaneously with the hot pressing region 3. The handle structure 51 is formed by cutting and other processing techniques at the handle region 5, simultaneously forming the buffer portion 511. This eliminates the need for additional accessories such as soft handles or rubber rings, as in existing solutions, and eliminates the need for additional processing to create an inflatable structure. The handle region 5 and handle structure 51 are simple to manufacture and offer lower costs.
[0045] exist Figure 1 Based on Figure 2-Figure 4 The handle structure 51 is provided with a lifting hole 513, located on the side of the buffer portion 511 facing the receiving chamber 4. After the finger 8 passes through the lifting hole 513 and is lifted upward, it contacts the buffer portion 511, eliminating the pinching sensation. The lifting hole 513 allows the hand to pass through the handle structure 51, completing the lifting operation of the bag body 100 with the finger 8.
[0046] Furthermore, the handle structure 51 is provided with a lug 512, which is connected to the cushioning portion 511, forming a bend 5121 at the connection. The lug 512 and the cushioning portion 511 are bent at the bend 5121, allowing the lug 512 to be tilted toward the outside of the bag body 100. When a finger 8 passes through the lifting hole 513 and tilts the lug 512, which is connected to the cushioning portion 511, toward the outside of the bag body 100, the bend 5121 bends and deforms to form a large arc. When the finger 8 is lifting, the fingertip 81 contacts the bent and deformed bend 5121, further preventing the finger 8 from feeling constricted.
[0047] In some embodiments, at both ends of the bending region 5121, the handle 512 has protruding lugs 5123 projecting toward the buffer portion 511. The lugs 5123 prevent the bending region 5121 from exceeding the deformation limit of the bag body 100 when bending, thereby improving the carrying capacity of the handle structure 51.
[0048] Specifically, the ends of the lugs 5123 that protrude toward the cushioning portion 511 are rounded. Because this location represents a sudden change in shape, the rounded corners further enhance the load-bearing capacity of the handle structure 51, reduce stress concentration at this location, and prevent fatigue cracking after long-term use. The ends of the lugs 5123 that are away from the bend 5121 are also rounded. Because this location contacts the fingertips 81, the rounded corners prevent discomfort such as stinging on the fingers 8.
[0049] Furthermore, the length of the bending region 5121 is less than or equal to the length of the lifting hole 513. When carrying a heavy load, if the length of the bending region 5121 is greater than the length of the lifting hole 513, the buffer portion 511 will be severely bent and deformed, and the finger 8 will directly contact the hot pressing zone 3 connected to the buffer portion 511, causing an uncomfortable pinching sensation. Therefore, setting the length of the bending region 5121 to be less than or equal to the length of the lifting hole 513 can prevent the handle structure 51 from causing a pinching sensation when carrying heavy loads, and indirectly increase the effective volume of the accommodating cavity 4.
[0050] In this embodiment, the handle tab 512 is formed by cutting the handle region 5 along an unsealed cut line 514 at the location of the pull hole 513. After the handle tab 512 is flipped toward the outside of the bag body 100, the pull hole 513 is formed at the location of the handle region 5. That is, by cutting along the unsealed cut line 514, the pull hole 513 and the tab 512 are two related structures formed simultaneously on the handle structure 51. This simplifies the processing of the handle structure 51, further reducing the production cost of the non-binding packaging bag and improving processing efficiency.
[0051] In addition, in this embodiment, the side of the ear 512 facing the accommodating cavity 4 is locally hot-pressed, such as Figure 2As shown, local hot pressing is performed on one side of the handle 512 to form a local hot pressing position 5122. During use, if the first diaphragm 1 and the second diaphragm 2 are respectively flipped toward the outside of the bag body 100, and the fingers 8 are inserted and pulled multiple times, wrinkles and bends are likely to appear in the later stage, making the handle 512 unsightly and affecting the gripping feel. After local hot pressing, the overall shape of the handle 512 can remain unchanged during the service life of the bag body 100, with better durability and more beautiful appearance, and the gripping feel of the hand can be maintained. The area occupied by the local hot pressing position 5122 of the handle 512 should be as small as possible. During production, the local hot pressing position 5122 can be obtained by partially drawing the cutting line 514 through the hot pressing zone 3 on the side facing the accommodating cavity 4, thereby reducing the processing steps of the handle structure 51, further improving processing efficiency and reducing production costs.
[0052] In some embodiments, the lifting hole 513 is curved toward the receiving cavity 4, with rounded corners at both ends. The curved lifting hole 513 conforms to the actual spatial state of the hand when inserted into the lifting hole 513, and also provides a larger cushioning area 511 for the fingertips 81, making lifting the handle structure 51 more convenient and comfortable.
[0053] In summary, because the handle structure 51 includes the buffer portion 511 and the buffer portion 511 is located in the non-hot-pressed area, when the bag 100 is lifted or tilted, the buffer portion 511 is soft and elastic and easily deformed under force. The fingers 8 have soft contact with the buffer portion 511, making lifting more comfortable and without a pinching sensation. Furthermore, during the lifting process, as the deformation increases, the contact area between the fingertips 81 and the buffer portion 511 also increases, further avoiding the pinching sensation.
[0054] The handle structure 51 is provided with a pulling hole 513 and a lifting ear 512, and a bending area 5121 is formed at the connection between the lifting ear 512 and the buffer portion 511. The lifting ear 512 is flipped and bent at the bending area 5121, further increasing the contact area between the fingertips 81 and the handle structure 51, making the pulling of the fingers 8 more comfortable.
[0055] Secondly, the handle area 5 is a non-hot-pressed area surrounded by the hot-pressed area 3. It can solve the problem of pinching the handle when pulling without adding other accessories. The manufacturing process is simple and the cost is lower.
[0056] In addition, a lug portion 5123 is provided on the handle 512, so that the bending zone 5121 can bend as the handle 512 is flipped toward the outside of the bag body 100, and rounded corners are provided on the end of the lug portion 5123 that protrudes toward the buffer portion 511 and the end of the lug portion 5123 that is away from the bending zone 5121, thereby improving the force-bearing capacity and durability of the bending zone 5121 and increasing the service life of the handle structure 51.
[0057] Example 2
[0058] exist Figure 1-Figure 4 Based on Figure 5 The structure of the anti-strangulation packaging bag in this embodiment is the same as that in embodiment 1. However, the difference is that the handle area 5 can be provided at any edge of the bag body 100 or at the intersection of the edges according to actual needs, and the handle area 5 can be provided in more than one place.
[0059] In this embodiment, there are two handle areas 5, and one of the handle structures 51 is arranged at the intersection of the edges of the bag body 100, and the lifting hole 513 of the handle structure 51 is inclined to any of the intersecting edges. The second handle structure 51 is arranged on an edge adjacent to the aforementioned handle structure 51, and the lifting hole 513 of the second handle structure 51 is parallel to the edge. When the finger 8 pulls the aforementioned handle structure 51, the bag body 100 is lifted at a certain angle along the horizontal plane. When dumping is required, the finger 8 can be rotated and tilted at a certain angle along the horizontal plane to complete the dumping work, which is simple and convenient to use. If the required tilting angle is larger, the finger 8 of the other hand can be used to pull the second handle structure 51, so that the bag body 100 can easily dump the items in the accommodating cavity 4, and the bag body 100 will not be softened and deformed due to the excessive weight of the items, which will affect the dumping effect.
[0060] Example 3
[0061] exist Figure 1-Figure 4 Based on Figure 6-Figure 7 This embodiment, based on Example 1, further includes a connecting piece 6. Connecting piece 6 is located on the side of the bag body 100 away from the handle area 5 and serves to connect the accommodating cavity 4 with the outside of the bag body 100. With connecting piece 6, the hand-free packaging bag of this embodiment can function similarly to existing plastic bottles, storing liquids or granular solids in the accommodating cavity 4 and allowing for pouring.
[0062] Furthermore, the connecting member 6 is located at the intersection of the edges of the bag body 100 and is provided with a connecting opening 61 that opens obliquely to any of the intersecting edges. In this embodiment, the handle structure 51 and the connecting opening 61 are provided obliquely to any of the edges of the bag body 100. When pouring, the contents of the accommodating cavity 4 can be poured out without a large angle of movement, making the pouring process smoother and more convenient.
[0063] Furthermore, the connecting piece 6 is hot pressed between the first membrane 1 and the second membrane 2, and the connecting piece 6 is a plastic piece that can control whether the accommodating cavity 4 is connected to the outside of the bag body 100. In some embodiments, the connecting piece 6 can be made of Figure 6The tubular plastic member 62 with a sealing cap shown is used for liquids such as laundry detergent, beverages, etc. Due to the flow characteristics of liquids, the tubular plastic member 62 with a sealing cap can make the pouring flow controllable. After pouring, the sealing cap is screwed on to close the communication port 61. For powdered or granular solids, the following method can also be used. Figure 7 The plastic sealed zipper 63 shown in the embodiment has lower costs and simpler manufacturing processes, effectively reducing packaging and transportation costs for low-value products such as plant fertilizers and feed. Of course, the connecting member 6 is not limited to the plastic parts listed above. Alternatively, a plastic switch faucet, a one-way valve fitting, an extrusion pump, or other plastic parts that can be hot-pressed between the first diaphragm 1 and the second diaphragm 2 and control whether the accommodating chamber 4 is connected to the outside of the bag body 100 can be used.
[0064] In summary, the anti-strangulation packaging bag provided with the connecting member 6 can effectively replace most plastic bottles used for batch dumping and sealed storage of large-volume items. Plastic packaging bags have a lower plastic content than plastic bottles. Given a constant storage capacity, the packaging bag described in this embodiment offers the advantages of being more environmentally friendly and cost-effective while preventing strangulation.
[0065] The above content is merely an example and illustration of the structure of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these obvious alternative forms are all within the scope of protection of the present invention.
