Description

Technical Field

[0001] The utility model relates to a sealing bag, in particular to a wide single-rib sealing bag. Background Art

[0002] Rib sealing bags are often used to store and seal items. They consist of a bag body and a pair of sealing strips at the bag mouth. By pressing the two sealing strips on both sides of the bag opening to connect them, the bag is sealed to prevent leakage or damage of items, and it has the function of dust and moisture proof.

[0003] Existing sealing bags usually have only one simple sealing rib, that is, a convex strip and a concave strip, and a groove is formed in the concave strip for the convex strip to be embedded in. When sealing, the convex strip and the concave strip on both sides are pressed to make the convex strip embedded in the groove to achieve sealing. When opening, the convex strip and the concave strip are pulled on both sides of the bag mouth to separate and open the bag. Although the operation is relatively convenient, when pressing the sealing rib to seal the bag, it is easy to press unevenly and the pressure in some places is not enough, which will cause partial gaps between the convex strip and the concave strip, loose connection, and poor sealing; and when pulling the sealing rib to open the bag, the stress is easy to concentrate on the single sealing rib, resulting in the bag tearing at the sealing rib.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example:

[0027] like Figure 1-Figure 5 As shown, a wide single-rib sealing bag comprises a bag body 1, a first sealing rib 11 is provided at the bag opening of the bag body 1, the first sealing rib 11 comprises a first rib member 2 and a second rib member 3 which are respectively located on both sides of the bag body 1 and are connected to each other, the first rib member 2 comprises a connecting groove composed of a first keel 21 and a second keel 22, at least one dividing strip 23 is provided in the connecting groove, the dividing strip 23 divides the connecting groove into at least two, and the second rib member 3 comprises at least two rib strips which are connected to the connecting groove in a one-to-one correspondence.

[0028] A partition strip 23 is arranged in the connecting groove of the first rib member 2, and the partition strip 23 divides the connecting groove into multiple channels. The multiple connecting grooves are connected with the multiple rib strips in a one-to-one correspondence, which can provide a larger structural support area and connection sealing area for the bag body 1, and improve the bearing capacity, compression resistance and tensile resistance to external forces; it can more evenly press the bag opening, and isolate the bag opening space in multiple layers to avoid gas circulation, thereby ensuring a more reliable sealing effect; when pressing the first rib member 2, a sealed connection between multiple rib strips and the connecting grooves can be achieved by pressing once, thereby preventing the problem of poor sealing due to loose connection of a single-channel sealed rib caused by uneven pressing.

[0029] Moreover, the partition strip 23 can also improve the strength of the tearing surface of the sealing bag, making it difficult to tear at the sealing opening, thereby improving the durability and service life of the sealing bag.

[0030] When the connecting groove is divided into two, the two connecting grooves are divided into an upper connecting groove 24 and a lower connecting groove 25, and the two ribs are respectively an upper rib 31 and a lower rib 32. When the first rib member 2 and the second rib member 3 are connected, the upper rib 31 is embedded in the upper connecting groove 24, and the lower rib 32 is embedded in the lower connecting groove 25.

[0031] The outer edges of the first keel 21 and the second keel 22 are both provided with hooks 26 bent inward, the upper edge of the upper rib strip 31 is provided with an upper groove 33 correspondingly connected to the hook 26 of the first keel 21, and the lower edge of the lower rib strip 32 is provided with a lower groove 34 correspondingly connected to the hook 26 of the second keel 22. The first rib member 2 and the second rib member 3 are connected by the hooks 26 and grooves on the upper and lower sides, thereby increasing the connection strength of the bag opening.

[0032] The side of the rib strip facing the first rib member 2 is provided with a plurality of grooves 35 along the length direction. The structure of providing a plurality of grooves 35 on the rib strip allows a certain gap to exist when the rib strip is connected to the first rib member 2, so that it can be connected by pressing with less force, and while ensuring a certain sealing performance, it can also disperse stress, thereby enhancing the overall structural strength of the sealed bag when stretched or squeezed, and reducing the risk of tearing or damage in local areas of the bag. Reasonably designed grooves 35 can also reduce the amount of materials used and reduce costs while ensuring connection strength and sealing performance.

[0033] The depth of the groove 35 of the upper rib strip is greater than that of the groove 35 of the lower rib strip. The depth of the groove 35 of each rib strip gradually decreases from top to bottom, and the sealing performance gradually increases, which can provide different degrees of sealing performance, structural support and strengthening effects at different positions of the bag.

[0034] A second sealing rib 12 is provided below the first sealing rib 11, and the second sealing rib 12 includes a concave rib buckle strip 41 located on one side of the bag body 1 and a convex rib buckle strip 43 located on the other side of the bag body 1, and the concave rib buckle strip 41 and the convex rib buckle strip 43 are connected to each other in a corresponding manner. The second sealing rib 12 further ensures the sealing of the sealed bag to prevent the sealed bag from being accidentally opened.

[0035] The concave bone buckle strip 41 is provided with downwardly protruding clamping strips 42 on both the upper and lower inner sides; the convex bone buckle strip 43 is provided with buckle grooves 44 corresponding to the clamping edge on both the upper and lower sides. The concave bone buckle strip 41 and the convex bone buckle strip 43 are connected by the double-sided clamping strips 42 and the buckle grooves 44, and the connection strength and sealing performance are high.

[0036] An extension part 5 is further provided above the first sealing rib 11, and a plurality of ridges 51 are provided on the inner and / or outer side of the extension part 5. The design of the ridges 51 on the extension part 5 increases the friction force, making it easier to separate the two layers of the bag opening, thereby opening the sealed bag.

[0037] The utility model adopts a first sealing rib 11 and a second sealing rib 12, and the number of the first sealing rib 11 and the second sealing rib 12 is not limited. The first sealing rib 11 plays a role of a larger structural support area, compresses the bag opening more evenly, alleviates the stress concentration phenomenon, and improves the compression, tension and tearing strength of the sealed bag; the second sealing rib 12 plays a role in improving the sealing and connection strength. When the first sealing rib 11 is accidentally opened, the second sealing rib 12 is still there for sealing protection.

[0038] The parts not described in detail in the present invention are prior art and thus will not be described in detail here.
