Description

Technical Field

[0001] This utility model relates to the field of various product packaging technology, and in particular to a hand-pressed multi-purpose product compression bag. Background Technology

[0002] Compression bags play an important role in daily life and industrial applications, especially in the storage of goods. By removing air, compression bags can reduce the contact between goods and oxygen, thereby slowing down the oxidation process and preventing the goods from deteriorating.

[0003] However, existing compression bags have some shortcomings. First, they have poor sealing performance and are prone to air leakage, which affects the compression effect and the quality of the stored items. Second, they require additional equipment such as vacuum pumps to achieve good compression, which increases the complexity and cost of use. Finally, they have a high air leakage rate, are not durable enough, cannot be reused, and are easily damaged or torn during use, leading to seal failure.

[0004] For example, CN201472845U discloses a hand-rolled vacuum compression bag, which includes at least two rollable protective films that are mutually bonded around their perimeters. One longitudinal end of the protective film of the vacuum compression bag is provided with a closable opening, and at least one air outlet is provided on the side edge connected to the bottom edge of the opposite end. Multiple spaced-apart adhesive points are provided at the end where the air outlet is provided. The multiple adhesive points are distributed laterally along the vacuum compression bag, and the gap between adjacent adhesive points and the air outlet form a one-way exhaust channel for the vacuum compression bag.

[0005] However, in actual use, achieving a seal solely through adhesive points is prone to incomplete sealing, allowing air to re-enter the bag, affecting the compression effect and the quality of food preservation.

[0006] Therefore, a hand-operated multi-purpose item compression bag is provided to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a hand-pressed multi-purpose compression bag for items. By manually pressing to expel air from the bag, the air inside can be quickly expelled, allowing the items to achieve the desired compression effect in a short time. This improves the overall sealing ability, strength, puncture resistance, and abrasion resistance of the compression bag, effectively preventing the penetration of water vapor, oxygen, and other gases. It allows for repeated use, reduces unnecessary waste of packaging materials, and thus saves resources.

[0008] To achieve the above objectives, this utility model provides a hand-pressed multi-purpose item compression bag, including a compression bag, a slide rail zipper disposed on the top of the compression bag, and a one-way exhaust valve disposed on the bottom of the compression bag. The compression bag includes an outer compression bag layer and an inner compression bag layer, with two intermediate layers disposed between the outer compression bag layer and the inner compression bag layer.

[0009] Preferably, the outer layer of the compression bag is a PET layer, the inner layer of the compression bag is a PE layer, and the two intermediate layers are respectively an aluminum foil layer and a PA layer.

[0010] Preferably, the one-way exhaust valve includes an exhaust valve passage and an exhaust valve disposed inside the exhaust valve passage.

[0011] Preferably, the exhaust valve channel is configured as an electrostatic adsorption membrane.

[0012] Preferably, the exhaust valve is configured as a nano-micro suction exhaust valve, and the surface of the nano-micro suction exhaust valve is provided with multiple nanofibers.

[0013] Preferably, the slide rail zipper includes a slide rail assembly and a lock head disposed on the slide rail assembly. The slide rail assembly includes two symmetrically arranged first slide rails and second slide rails. The first slide rails are provided with a plurality of grooves, and the second slide rails are provided with a plurality of protrusions corresponding to the grooves. The first slide rails and the second slide rails are fixed together by the grooves and the protrusions.

[0014] Therefore, the hand-pressed multi-purpose item compression bag of this utility model with the above-described structure has the following beneficial effects:

[0015] (1) The compression method of the compression bag in this solution is manual pressing. The air can be sealed by manually pressing to release the air, which can quickly expel the air in the bag and make the item achieve the ideal compression effect in a short time. This reduces the reliance on additional tools and saves more time and effort.

[0016] (2) The one-way exhaust valve of this solution has the advantages of simple structure and strong sealing ability. It adopts a material with strong adsorption and special manufacturing process. When there is no pressure, the exhaust valve and the exhaust valve channel will automatically close, effectively preventing gas from flowing back into the interior of the compression bag and ensuring that the compression bag reaches a higher vacuum when closed.

[0017] (3) The compression bag of this solution uses multiple composite materials. By combining materials with different properties, the overall strength and wear resistance of the compression bag can be significantly improved, the puncture resistance of the bag can be increased, sharp objects can be prevented from penetrating the bag, and the safety of the contents can be protected. At the same time, the multi-layer structure has excellent barrier properties, which can effectively block the penetration of water vapor, oxygen and other gases, and extend the shelf life of the items or other perishable items.

[0018] (4) The hand-pressed compression bag in this solution has a simple structure and allows for repeated use, which can reduce unnecessary waste of packaging materials, thereby saving resources and reducing the cost of long-term use of compression bags.

[0019] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] like Figure 1-4 As shown, this embodiment provides a hand-pressable multi-purpose item compression bag, including a compression bag 1. The compression bag 1 includes an outer compression bag layer 2 and an inner compression bag layer 3. Two intermediate layers 4 are provided between the outer compression bag layer 2 and the inner compression bag layer 3. The outer compression bag layer 2 is a PET layer, which has good rigidity, transparency and barrier function. The inner compression bag layer 3 is a PE layer, which has good heat sealing and flexibility. The two intermediate layers 4 are respectively an aluminum foil layer and a PA layer. The aluminum foil layer has a good barrier effect on gas, moisture and light, and has a certain heat reflection performance, which can prevent air and moisture from entering the interior of the compression bag 1, thereby effectively preventing food oxidation. The PA layer can enhance the strength, puncture resistance and chemical stability of the compression bag 1. The multi-layer composite material can enhance the service life of the compression bag 1, so that the compression bag 1 can be used repeatedly and is not worn.

[0030] The top of the compression bag 1 is provided with a slide rail zipper 5. The slide rail zipper 5 includes a slide rail assembly 6 and a lock 7 provided on the slide rail assembly 6. The slide rail assembly 6 includes two symmetrically arranged first slide rails 8 and second slide rails 9. The first slide rail 8 is provided with a plurality of grooves 10, and the second slide rail 9 is provided with a plurality of protrusions 11 corresponding to the grooves 10. The first slide rail 8 and the second slide rail 9 are fixed by the grooves 10 and the protrusions 11.

[0031] The bottom of the compression bag 1 is provided with a one-way exhaust valve 12, which includes an exhaust valve channel 13 and an exhaust valve 14 disposed inside the exhaust valve channel 13.

[0032] The exhaust valve channel 13 is set as an electrostatic adsorption membrane. The electrostatic adsorption membrane achieves the adsorption effect by generating static charge on the material surface. When two surfaces with opposite charges come into contact, they will attract each other, thereby achieving closure. This material does not require any glue or adhesive and can achieve good sealing performance by relying on electrostatic action. It can be used repeatedly and can be opened and closed many times without losing its adsorption performance under frequent opening and closing.

[0033] The exhaust valve 14 is configured as a nano-micro suction exhaust valve. The surface of the nano-micro suction exhaust valve is provided with multiple nanofibers 15. The size of the nanofibers 15 is set to several nanometers to tens of nanometers. They can form a large number of tiny contact points with the surface of the object they are in contact with, producing an adhesion effect similar to that of a gecko's toe. When two surfaces come into contact, the air between the nanofibers 15 is squeezed out, forming a tiny vacuum area, which generates a strong adsorption force. This adsorption force enables the exhaust valve 14 to automatically close upon contact, and the sealing performance is excellent.

[0034] In actual use, the compression bag 1 is pressed directly, creating a pressure difference between the inside and outside of the compression bag 1. This causes the exhaust valve channel 13 and the exhaust valve 14 to open. The gas inside the compression bag 1 is discharged through the exhaust valve 14 to the exhaust valve channel 13, and then discharged into the external environment through the exhaust valve channel 13. After the gas inside the compression bag 1 is completely discharged, the pressing is stopped. Due to the high density and small size of the nanofibers 15, the exhaust valve 14 has a very strong adsorption capacity and closes quickly upon contact to maintain good sealing. At the same time, the exhaust valve channel 13 automatically closes under the electrostatic adsorption effect to prevent gas from the external environment from entering the compression bag 1.

[0035] Example 2

[0036] like Figure 5 As shown, this embodiment provides a hand-operated multi-purpose item compression bag, with a one-way exhaust valve 12 located on the side of the compression bag 1; the rest of the specific implementation is the same as in embodiment 1.

[0037] Therefore, this utility model provides a hand-pressed multi-purpose compression bag with the above-mentioned structure. The compression method is manual pressing, which quickly expels the air inside the bag by manually pressing to achieve the ideal compression effect in a short time. In addition, the one-way exhaust valve uses a highly absorbent material and a special manufacturing process, which has the advantages of simple structure and strong sealing ability. The compression bag uses multiple composite materials, which significantly improves the overall strength and wear resistance of the compression bag, effectively blocks the penetration of water vapor, oxygen and other gases, allows for repeated use, and can reduce unnecessary waste of packaging materials, thereby saving resources.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
