Description

Technical Field

[0001] This utility model relates to the field of waist-cinching packaging bag technology, and more particularly to waist-cinching packaging bags with built-in aluminum foil bags. Background Art

[0002] Packaging bags are bags used to package various items, making it convenient to transport and store goods during the production and distribution process. They are widely used in daily life and industrial production. Waist-sealed packaging bags are used to store and carry items, and they are sealed with a drawstring.

[0003] For example, a built-in aluminum foil waist-tightening packaging bag with patent number "CN213263606U" includes a bag body and a drawstring. This utility model is equipped with a limiting and protective device consisting of a pressing plate, a clamping plate, a fixed rotating shaft, and fixed teeth. The two clamping plates are opened by rotating the fixed rotating shaft and contacting the lower part of the bag body to tighten the bag opening. The bag body is located between the two clamping plates. By grasping the two pressing plates by hand and applying force, the two clamping plates are rotated by the fixed rotating shaft to begin closing, squeezing the bag body and squeezing out excess items. The two clamping plates are fixed by interlocking fixed teeth to fix the bag body, so that it can tighten and shrink the bag opening. The beneficial effect is that by contacting and squeezing the upper side of the bag body through the limiting and protective device, excess items are squeezed out of the bag body, leaving space for tightening and shrinking. When tightening and closing the bag opening, it will not be unable to close due to too many items, nor will it cause the tightened and closed bag opening to be stretched open due to too many items.

[0004] Aluminum foil, with its waterproof and heat-insulating properties, is commonly used in various packaging fields, and is most suitable for food packaging. For example, lunchboxes brought by office workers are often packaged in aluminum foil bags to keep the food warm. For this type of waisted packaging bag, the internal space needs to be large enough to hold the lunchbox stably. If it is a flat-mouthed aluminum foil bag as shown in the patent above or a common one on the market, the lunchbox is prone to tilting inside the bag, causing leakage. If a stand-up pouch is used in the patent above, the sealing effect of the clamps is not very good. Because the stand-up pouch containing the lunchbox is subjected to forces from multiple directions, the clamps are prone to break open, resulting in poor sealing. If the sealing effect is poor, the heat inside the lunchbox can easily escape from the opening of the waisted bag, resulting in poor heat preservation. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the sealing and heat preservation effect of aluminum foil waistbands of different styles is not very good in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a built-in aluminum foil bag waist-cinching packaging bag, comprising a packaging bag and an aluminum foil layer, wherein the aluminum foil layer is disposed on the inner wall of the packaging bag, the upper end of the packaging bag is provided with a drawstring groove, a waist-cinching rope is disposed in the drawstring groove, the opening of the packaging bag is provided with a sealing component, the sealing component comprising a base support, a pressure plate and a positioning plate, the base support is provided with a support shaft, the pressure plate is adjustablely disposed on the support shaft, the positioning plate is disposed at the upper end of the support shaft, the positioning plate is provided with a positioning mechanism, and the two ends of the waist-cinching rope are adjustablely disposed on the positioning mechanism.

[0007] In a preferred embodiment, the two sides of the drawstring groove are symmetrically provided with side grooves communicating with the outside. There are two waist-cinching ropes arranged symmetrically. One end of the waist-cinching rope passes through one of the side grooves into the drawstring groove and exits from the same side groove. The two ends of the waist-cinching rope are spliced ​​together. By cooperating with the side grooves and the drawstring groove, when performing the waist-cinching operation, the waist-cinching ropes can be pulled out by pulling the two waist-cinching ropes at the same time, thereby achieving the effect of tightening the opening of the packaging bag.

[0008] In a preferred embodiment, the support shaft is provided with an external thread, and the internal center of the pressure plate is rotatably mounted on the support shaft. The support shaft and the pressure plate are rotatably connected by a thread, which facilitates the adjustment of the pressure plate to move up and down on the support shaft.

[0009] In a preferred embodiment, a first magnetic sheet is provided on the upper part of the interior of the base, and a second magnetic sheet is provided on the lower part of the interior of the pressure plate, which is attracted to the first magnetic sheet. The mutual attraction between the first and second magnetic sheets further ensures the stability of the pressure plate on the support shaft and prevents the pressure plate from moving on the support shaft after a period of use, thus preventing the pressure plate from detaching from the surface of the packaging bag.

[0010] In a preferred embodiment, two positioning mechanisms are provided, symmetrically arranged on the positioning disk. Each positioning mechanism includes a U-shaped block, an adjusting plate, and a pressure plate. The U-shaped blocks are symmetrically arranged at both ends of the positioning disk. One side of the pressure plate is rotatably mounted on the inner end of the U-shaped block via a pivot. The upper end of the adjusting plate is rotatably mounted above the inner side of the U-shaped block. The inner side of the adjusting plate is connected to the inner wall of the U-shaped block via a spring. The lower end of the adjusting plate is engaged with the upper end of one end of the pressure plate. When positioning the waist-cinching rope, it can be slid into the U-shaped block through the opening and placed on the pressure plate. Then, push the pressure plate downwards so that the end with the waist-cinching rope abuts against the inner wall of the U-shaped block until it reaches the lower end of the adjusting plate. This causes the upper end of the pressure plate to engage with the lower end of the adjusting plate. Conversely, to remove it, the adjusting plate can be squeezed to separate it from the pressure plate. Then, pull the waist-cinching rope upwards to rotate the pressure plate and bring it to the top of the adjusting plate. At this point, the waist-cinching rope separates from the positioning mechanism, and can be removed from the opening of the U-shaped block.

[0011] In a preferred embodiment, the outer sides of the base, support shaft, and pressure plate are all provided with a sponge layer. The sponge layer above the base extends outward. This sponge layer is a heat-insulating sponge. By providing the sponge layer, the heat insulation effect of the base and support shaft on the inside of the packaging bag can be guaranteed. At the same time, the sponge has soft properties, which can fit more closely to the inner wall of the packaging bag after the waist is tightened, thus preventing heat loss as much as possible.

[0012] In a preferred embodiment, the outer side of the aluminum foil layer is provided with a hook and loop fastener, and the inner wall of the packaging bag is provided with a rough hook and loop fastener that is adapted to the hook and loop fastener. The mutual adhesion and adaptation of the hook and loop fasteners facilitates the replacement of the internal aluminum foil layer.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model uses a sealing component at the sealing point of the packaging bag to press and seal the sealed area of ​​the tightened packaging bag. This prevents the waist rope at the sealing point from loosening and ensures the sealing performance, preventing internal heat loss. Furthermore, the two ends of the tightened waist rope are pulled taut and placed on a positioning mechanism to position the length of the waist rope and prevent it from loosening. The positioning mechanism is located on a positioning plate, and the positioned waist ropes are close to each other, making it easy for people to lift them.

[0015] 2. This utility model facilitates the replacement of the internal aluminum foil layer by using interlocking hook and loop fasteners. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a waist-cinching packaging bag with an internal aluminum foil bag, comprising a packaging bag 1 and an aluminum foil layer 2. The aluminum foil layer 2 is disposed on the inner wall of the packaging bag 1. The upper end of the packaging bag 1 is provided with a drawstring groove 3, and a waist-cinching rope 4 is threaded through the drawstring groove 3. The opening of the packaging bag 1 is provided with a sealing component, which includes a bottom support 5, a pressure plate 6, and a positioning plate 7. The bottom support 5 is provided with a support shaft 8. The pressure plate 6 is adjustablely threaded onto the support shaft 8. The positioning plate 7 is disposed at the upper end of the support shaft 8 and is provided with a positioning mechanism. The two ends of the waist-cinching rope 4 are adjustablely threaded onto the positioning mechanism. When performing the waist-cinching and sealing operation on the packaging bag 1, the bottom support 5 can be placed inside the packaging bag 1, and the support shaft 8 can be threaded out to the outside of the packaging bag 1. By tightening the drawstring groove 3, the waist-cinching rope 4 is pulled... The opening of bag 1 is tightened, at which point the top of the bottom support 5 is tightly fitted to the upper inside of the tightened bag 1. Then, by adjusting the pressure plate 6, it is moved downward on the support shaft 8 until the bottom of the pressure plate 6 is tightly fitted to the upper outer side of the bag 1. Through the cooperation of the bottom support 5, the pressure plate 6, and the support shaft 8, the opening of the tightened bag 1 is pressed and sealed. This prevents the waist rope 4 at the opening from loosening and ensures the sealing of the opening, preventing internal heat loss. Then, the two ends of the tightened waist rope 4 are pulled tight and set on the positioning mechanism to position the length of the waist rope 4 and prevent it from loosening. The positioning mechanism is set on the positioning plate 7, and the positioned waist ropes 4 are close to each other, making it easy for people to lift them.

[0026] like Figure 1-6 As shown, the two sides of the cord threading groove 3 are symmetrically provided with side grooves 9 that communicate with the outside. There are two waist-tightening cords 4, which are symmetrically arranged. One end of the waist-tightening cord 4 is inserted into the cord threading groove 3 from one side groove 9 and exits from the same side groove 9. The two ends of the waist-tightening cord 4 are spliced ​​together. Through the cooperation of the side groove 9 and the cord threading groove 3, when performing the waist-tightening operation, the two waist-tightening cords 4 can be pulled out by pulling the two waist-tightening cords 4 at the same time, thereby achieving the effect of tightening the opening of the packaging bag 1.

[0027] like Figure 1-6 As shown, the support shaft 8 is provided with an external thread, and the internal center position of the pressure plate 6 is rotatably mounted on the support shaft 8. The support shaft 8 and the pressure plate 6 are rotatably connected by a thread, which facilitates the adjustment of the pressure plate 6 to move up and down on the support shaft 8.

[0028] like Figure 1-6 As shown, a first magnetic sheet 10 is provided on the upper part of the interior of the base 5, and a second magnetic sheet 11 is provided on the lower part of the interior of the pressure plate 6, which is attracted to the first magnetic sheet 10. The mutual attraction between the first magnetic sheet 10 and the second magnetic sheet 11 further ensures the stability of the pressure plate 6 on the support shaft 8, and prevents the pressure plate 6 from moving on the support shaft 8 after a period of use, thus preventing the pressure plate 6 from detaching from the surface of the packaging bag 1.

[0029] like Figure 1-6 As shown, there are two positioning mechanisms symmetrically arranged on the positioning disk 7. Each positioning mechanism includes a U-shaped block 12, an adjusting plate 13, and a pressure plate 14. The U-shaped block 12 is symmetrically arranged at both ends of the positioning disk 7. One side of the pressure plate 14 is rotatably positioned at the inner end of the U-shaped block 12 via a rotating shaft 15. The upper end of the adjusting plate 13 is rotatably positioned above the inner side of the U-shaped block 12. The inner side of the adjusting plate 13 is connected to the inner wall of the U-shaped block 12 via a spring 16. The lower end of the adjusting plate 13 is engaged with the upper end of one end of the pressure plate 14. When positioning the waist-cinching rope 4, the waist-cinching rope can be... 4. Slide the U-shaped block 12 into the interior through the opening and place it on the pressure plate 14. Then push the pressure plate 14 downward so that the end with the waist-cinching rope 4 abuts against the inner wall of the U-shaped block 12 until it is pushed to the lower end of the adjusting plate 13, so that the upper part of the pressure plate 14 is engaged with the lower end of the adjusting plate 13. Conversely, when removing it, the adjusting plate 13 can be squeezed to separate the adjusting plate 13 from the pressure plate 14. Then pull the waist-cinching rope 4 upward to rotate the pressure plate 14 to the upper part of the adjusting plate 13. At this time, the waist-cinching rope 4 is separated from the positioning mechanism. The waist-cinching rope 4 can be taken out from the opening of the U-shaped block 12.

[0030] like Figure 1-6 As shown, the outer sides of the base 5, support shaft 8 and pressure plate 6 are all provided with a sponge layer 17. The sponge layer 17 above the base 5 extends outward. The sponge layer 17 is a heat-insulating sponge. By setting the sponge layer 17, the heat insulation effect of the base 5 and support shaft 8 on the inside of the packaging bag 1 can be guaranteed. At the same time, the sponge has soft properties, which fits more closely with the inner wall of the packaging bag 1 after the waist is tightened, so as to prevent heat loss as much as possible.

[0031] like Figure 1-6 As shown, the outer side of the aluminum foil layer 2 is provided with a hook and loop fastener 18, and the inner wall of the packaging bag 1 is provided with a rough hook and loop fastener 19 that is adapted to the hook and loop fastener 18. By adapting the hook and loop fastener 18 and the rough hook and loop fastener 19 to each other, it is convenient to replace the aluminum foil layer 2 inside.

[0032] Working principle: When performing the waist-sealing operation on the packaging bag 1, the bottom support 5 can be placed inside the packaging bag 1, and the support shaft 8 can be passed through to the outside of the packaging bag 1. By tightening the rope groove 3, the opening of the packaging bag 1 is tightened. At this time, the top of the bottom support 5 is tightly fitted with the upper inside of the tightened packaging bag 1. Then, by adjusting the pressure plate 6, it is moved downward on the support shaft 8 until the bottom of the pressure plate 6 is tightly fitted with the upper outer side of the packaging bag 1. Through the cooperation of the bottom support 5, the pressure plate 6 and the support shaft 8, the sealed opening of the tightened packaging bag 1 is pressed and sealed. On the one hand, it prevents the waist-sealing rope 4 from loosening at the sealing point, and on the other hand, it ensures the sealing performance and prevents internal heat loss. Then, the two ends of the tightened waist-sealing rope 4 are pulled tight and placed on the positioning mechanism to position the length of the waist-sealing rope 4 and prevent it from loosening. The positioning mechanism is set on the positioning plate 7. The positioned waist-sealing ropes 4 are close to each other, making it easy for people to lift them.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
