Description

Technical Field

[0001] The present invention relates to the technical field of a sealing structure for sealing the sealing part of a vacuum compression storage bag, and in particular to a non-air-pumping sealing clip for a storage bag. Background Art

[0002] A vacuum compression storage bag is a device for compressing and storing daily necessities such as clothes and quilts. When actually used, daily necessities such as clothes and quilts are filled into the vacuum compression storage bag, and then the sealing part is sealed. Then, the air in the bag is discharged by using an air extraction and exhaust valve to perform vacuum compression storage on the stored items. However, based on the current structure of the vacuum compression storage bag, an air extraction and exhaust valve must be provided on the bag body during the compression operation. Therefore, when manufacturing the vacuum compression storage bag, a perforation needs to be opened on the bag body, and then the air extraction and exhaust valve is hermetically fixed at the perforation position. Generally, fixing methods such as heat sealing are used during the hermetic fixing, and the structure of the air extraction and exhaust valve is also relatively complex. Therefore, such a storage bag with a complex structure makes the manufacturing cumbersome and the production cost high. Summary of the Invention

[0003] The purpose of the present invention is to design a non-air-pumping sealing clip for a storage bag that simplifies the structure of the vacuum compression storage bag, makes the manufacturing simple, and realizes the exhaust function while sealing the storage bag.

[0004] A non-air-pumping sealing clip for a storage bag designed by the present invention includes a clip body. A sealing channel is provided on the clip body. It also includes a plug. An air outlet channel communicating with the sealing channel is provided on the clip body. The sealing part of the storage bag is inserted into the sealing channel. At least a part of the plug penetrates through the air outlet channel and then is inserted between the two sealing surfaces of the sealing part of the storage bag and is positioned on the clip body. The clip body slides along the sealing part and applies pressure to seal the sealing part. The plug makes the sealing part of the storage bag not be completely sealed.

[0005] Preferably, the plug is slidably installed on the clip body, and a limiting structure is provided between the plug and the clip body to position the plug after it moves downward and is inserted between the two sealing surfaces of the sealing part of the storage bag.

A vertically-shaped long hole corresponding to the side plate is provided on the clip body, and the side plate is correspondingly inserted into the vertically-shaped long hole. A limiting protrusion is provided at the lower end of the vertically-shaped long hole. A positioning space for positioning the side plate is formed between the limiting protrusion and the inner wall at the lower end of the vertically-shaped long hole. After the plug moves downward, the bottom surface of the side plate is placed in the positioning space for positioning. The mutual cooperation between the side plate and the limiting protrusion forms a limiting structure.

[0007] Preferably, a side plate is provided on the side of the plug-in. A vertically elongated hole corresponding to the side plate is provided on the clamping body. A vertical plate extending vertically downward is provided at the outer end of the side plate. A positioning block is provided on the bottom side of the vertical plate. The positioning block is inserted into the vertically elongated hole. A limiting protrusion or a limiting strip is provided at the lower end of the vertically elongated hole. A positioning space for positioning the positioning block is formed between the limiting protrusion or the limiting strip and the inner wall of the lower end of the vertically elongated hole. After the plug-in moves downward, the top surface of the clamping body contacts the bottom surface of the side plate, so that the positioning block is inserted into the positioning space for positioning. The mutual cooperation between the positioning block and the limiting protrusion or the limiting strip forms a limiting structure.

[0008] Preferably, a long depression corresponding to the vertical plate is provided on the outer side of the clamping body at the position of the vertically elongated hole or on the inner wall of the air outlet channel at the position of the vertically elongated hole. The vertical plate is positioned in the long depression.

[0013] Preferably, the width of the side plate is less than or equal to the width of the vertical plate.

[0014] A kind of airtight seal clip for storage bags designed by the present invention, when sealing the sealing part of the storage bag, the plug-in is inserted between the two sealing surfaces of the sealing part, so that the sealing part of the storage bag is not completely sealed. At this time, the plug-in moves upward to make the already sealed sealing part partially unsealed to form an exhaust port, and then the storage bag is pressed to perform an exhaust compression operation. Therefore, this structural method enables the storage bag to realize the function of exhausting and exhausting air without setting an exhaust valve, further making the structure of the storage bag simpler, and the exhaust and exhausting air are more convenient, and the structure of the airtight seal clip is also relatively simple, thereby further achieving a significant reduction in production cost.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] As shown in the attached drawings, a non-air-pumping sealing clip for a storage bag described in this embodiment includes a clip body 2 and a plug-in member 3. A sealing channel 24 is provided on the clip body 2, and an air outlet channel 21 communicating with the sealing channel 24 is provided on the clip body 2. The sealing part 11 of the storage bag 1 is inserted into the sealing channel 24. At least a part of the plug-in member 3 passes through the air outlet channel 21 and then is inserted between the two sealing surfaces 111 of the sealing part 11 of the storage bag 1 and is positioned on the clip body 2. The clip body 2 slides along the sealing part 11 and applies pressure to seal the sealing part 11. And under the action of the plug-in member 3, the sealing part 11 of the storage bag 1 is not completely sealed, so that the sealing part 11 at the clip body position is in an open state, facilitating the exhaust operation of the storage bag. Further, in order to achieve reliable positioning after the plug-in member moves downward and avoid the situation that the plug-in member detaches when the clip body slides along the sealing part, the plug-in member 3 is slidably installed on the clip body 2, and a limiting structure is provided between the plug-in member 3 and the clip body 2 to position it after the plug-in member 3 moves downward and is inserted between the two sealing surfaces 111 of the sealing part 11 of the storage bag 1.

[0031] In this embodiment, the specific limiting structure is as follows: a side plate 31 is provided on the side of the plug-in member 3, a vertically-shaped long hole 22 corresponding to the side plate 31 is provided on the clip body 2, and a vertical plate 32 extending vertically downward is provided at the outer end of the side plate 31. A positioning block 321 is provided on the bottom side of the bottom end of the vertical plate 32. The positioning block 321 is inserted into the vertically-shaped long hole 22. A limiting protrusion 26 or a limiting strip 23 is provided at the lower end of the vertically-shaped long hole 22. A positioning space 221 for positioning the positioning block is formed between the limiting protrusion 26 or the limiting strip 23 and the inner wall of the lower end of the vertically-shaped long hole 22. After the plug-in member 3 moves downward, the top surface of the clip body 2 contacts the bottom surface of the side plate 31, so that the positioning block 321 is inserted into the positioning space 221 for positioning. The mutual cooperation between the positioning block 321 and the limiting protrusion 26 or the limiting strip 23 forms a limiting structure; it realizes the lifting movement of the plug-in member under the limitation of the positioning block and the vertically-shaped long hole, so that after the storage bag is pressed to exhaust, the situation that the plug-in member moves upward and detaches from between the two sealing surfaces of the sealing part of the storage bag, resulting in the separation of the plug-in member and the clip body, is avoided, so as to realize that even if the plug-in member rises, it can still be positioned on the clip body, avoiding the situation of plug-in loss, thereby further improving the use performance, and at the same time, the plug-in can be stably and reliably inserted between the two sealing surfaces of the sealing part of the storage bag. Among them, the side plate, the positioning block and the vertical plate are integrally combined into one structure.

[0032] In this embodiment, a long depression corresponding to the vertical plate 32 is provided on the outer side surface of the clip body 2 at the position of the vertically-shaped long hole 22 or on the inner wall of the air outlet channel 21 at the position of the vertically-shaped long hole 22. The vertical plate is positioned in the long depression; this structure makes the up and down lifting movement of the vertical plate stable and reliable, and the volume of the sealing clip is further reduced.

[0033] In this embodiment, a transverse groove 241 is provided on the inner wall of the sealing channel 24. The transverse groove can be set to only one. When sealing in the case of one transverse groove, after the sealing part of the storage bag is inserted into the sealing channel, a convex strip 112 formed on the outer side of the sealing part due to the arrangement of a zipper 12 is inserted into the transverse groove 241, so as to position the clamping body. When pressing on the sealing channel part of the clamping body, the zipper can also be pressed, so that the zipper can be sealed and buckled relatively quickly to prevent air from entering the bag again; or it can also be set to two arranged up and down. In the case of two transverse grooves 241, after the sealing part of the storage bag is inserted into the sealing channel, two convex strips 112 formed on the outer side of the sealing part due to the arrangement of two zippers 12 are respectively inserted into the two transverse grooves 241, so as to position the clamping body. When pressing on the sealing channel part of the clamping body, the zipper can also be pressed, so that the zipper can be sealed and buckled relatively quickly to prevent air from entering the bag again.

[0034] In this embodiment, a bevel 242 is provided at the opening edge of the sealing channel 24. Its structural setting makes the opening of the sealing channel in a flared state, so as to facilitate the corresponding insertion of the sealing part into the sealing channel, making it more convenient to use.

[0035] In this embodiment, a pointed end 33 is provided at the bottom end of the plug-in part 3, and the plug-in part 3 includes a plug board 301, or the plug-in part 3 includes multiple plug rods 302 connected to each other through a connecting body 303. Therefore, the bottom ends of the plug board or the multiple plug rods all have pointed ends. Thus, in the case of having pointed ends, it is convenient to insert the plug-in part between the two sealing surfaces of the sealing part, and the number of plug rods can be two or more than three.

[0036] In this embodiment, the width of the side plate 31 is less than or equal to the width of the vertical plate 32. When the width of the side plate is less than the width of the vertical plate, the upper port area of the air outlet channel is larger to increase the exhaust speed, and the side plate is a strip-shaped structure side plate. Multiple strip-shaped structure side plates can be arranged at intervals to make the connection between the vertical plate and the plug-in part more stable and reliable.

[0037] Based on the storage bag exhaust method realized by the above structure, its specific exhaust steps are as follows:

[0038] The sealing part of the storage bag is inserted into the sealing channel of the clamping body;

[0039] After at least a portion of the plug-in passes through the air outlet channel, it is inserted between the two sealing surfaces of the sealing part of the storage bag and positioned on the clamp. The clamp slides along the sealing part of the storage bag and applies pressure to seal the sealing part. Under the action of the plug-in, the sealed sealing part is kept in an open state at the position with the clamp. At this time, after the plug-in is operated to move upward so that at least a portion of the plug-in is separated from between the two sealing surfaces of the sealing part, the storage bag is compressed to cause the air in the bag to be discharged to the outside through the sealed opening position of the sealing part (the large-area exhaust port formed at the local position of the sealing part) and the air outlet channel; among them, when the plug-in does not move up, the storage bag can also be compressed to cause the air in the bag to be discharged to the outside through the sealed opening position of the sealing part (the small-area exhaust port formed at the local position of the sealing part) and the air outlet channel, but the effect is best when the exhaust is performed after the plug-in is moved upward.

[0040] After the bag body is exhausted, the plug is moved upward and separated from between the two sealing surfaces of the sealing portion of the storage bag. At this time, the clamp slides along the sealing portion of the storage bag again and applies pressure to seal the open position of the sealing portion.

[0041] Embodiment 2:

[0042] The present embodiment describes a vacuum-free sealing clamp for storage bags, the general structure of which is the same as that of the embodiment 1, but the only difference is that a side panel 31 is provided on the side of the plug-in 3, a vertical elongated hole 22 corresponding to the side panel 31 is provided on the clamp body 2, and the side panel 31 is correspondingly inserted into the vertical elongated hole 22, a limiting protrusion 26 is provided at the lower end of the vertical elongated hole 22, and a positioning space 221 for positioning the side panel is formed between the limiting protrusion 26 and the inner wall of the lower end of the vertical elongated hole 22, and after the plug-in 3 is moved downward, the bottom surface of the side panel 31 is placed in the positioning space 221 for positioning, and the side panel 34 cooperates with the limiting protrusion 26 to form a limiting structure, wherein the side panel and the plug-in are combined with each other into an integrated structure.

[0043] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
