Description

Technical Field

[0001] The present invention belongs to the technical field of self-sealing strips used for sealed bags, and particularly relates to a self-sealing strip having a tactile feedback function.

Background Art

[0002] A sealed bag is a packaging bag that can be automatically sealed simply by pressing. Common types include zip-lock (registered trademark) bags, blow bone (concave-convex bone) stand-up bags, etc. Usually, polyethylene (LDPE), linear low-density polyethylene (LLDPE), EVA, and PO materials are mainly used. Multilayer composite zipper bags can be used for the internal and external packaging of various small items (accessories, small metal products, toys), and can also be produced from food-grade raw materials. Self-sealing bags can store various small foods, tea, seafood, etc., have functions of moisture-proof, odor-proof, waterproof, and insect-proof, and can prevent the scattering of items. Self-sealing bags can also be used for the packaging of clothes and other daily items, with a wide range of applications. Also, by adding an anti-static masterbatch during the production of the blow film of the self-sealing bag, an anti-static self-sealing bag generally used in the electronics industry can be produced.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The key to the seal of a self-sealing bag lies in the self-sealing strip. The most common type currently is the finger-pressing type self-sealing strip. This type of self-sealing strip can be quickly sealed by pressing with a finger, is easy to use, and is widely used. However, when using this type of self-sealing strip, the touch feeling is poor, the feeling of the convex strip entering the female groove is relatively light, and it is difficult to feel with a finger, so it is difficult to judge whether it is firmly sealed after pressing.

Means for Solving the Problems

[0004] To solve the above technical problems, one of the technical solutions adopted in the present invention is A self-sealing strip with a tactile feedback function including a self-seal composed of a male end and a female end, The male end includes a male end carrier plate and a rib provided on the male end carrier plate. At least two sets of convex ribs are provided on the rib. Each set of convex ribs is symmetrically provided on both sides of the rib. The two sets of convex ribs are the first convex rib and the second convex rib respectively. A plurality of first grooves are provided on the side of the male end carrier plate away from the rib, and protrusions corresponding to the plurality of first grooves are further provided on the rib. The female end includes a female end carrier plate and a cavity provided on the female end carrier plate. The cavity fits with the rib, and a second groove for fitting with the plurality of protrusions is further provided in the cavity.

[0005] Furthermore, when the width of the first convex rib is W1 and the width of the second convex rib is W2, the width W1 of the first convex rib is narrower than the width W2 of the second convex rib.

[0006] A sealed bag made of a self-sealing strip, The self-sealing strip is provided at the opening of the sealed bag.

[0007] Furthermore, the sealed bag further includes a seal strip. The seal strip includes a male side engagement strip and a female side engagement strip. The male side engagement strip fits into the female side engagement strip to be sealed.

[0008] Furthermore, the seal strip is arranged in parallel with the self-sealing strip, and the distance between the seal strip and the self-sealing strip is H. The distance H is 3 to 5 mm.

[0009] The beneficial effects of the present invention are as follows. The convex strip of the self-sealing strip provided by the present invention is provided with at least two sets of convex ribs. The width ranges of the two sets of convex ribs are different, and the convex ribs form a stepped distribution that gradually expands from the upper end. When the convex strip gradually enters the cavity at the female end, the two sets of convex ribs enter the cavity one after another, generating a two-stage click vibration feedback. At the same time, since the self-sealing strip is made of plastic, after production is completed, subsequent processing is carried out. By using a device to continuously push down at intervals to generate a depression, a first groove is formed. Thereby, the upper surface of the convex strip is extruded to form a protrusion, and by continuously pressing the protrusion to generate a depression, a second groove is formed. Since a central depression cannot be formed during actual pressing, different degrees of deviation occur, forming an irregular second groove. Therefore, at the last moment when the convex strip enters the cavity at the female end, the convex strip irregularly enters the second groove, generating an irregular vibration frequency. The entire self-sealing strip continuously generates irregular vibrations of clicks during the sealing process. When pressed with a finger, the feedback during sealing can be clearly felt, improving the user's tactile feel and enabling the user to clearly feel whether the sealed bag is properly sealed.

Mode for Carrying Out the Invention

[0011] Hereinafter, preferred embodiments of the present invention will be described in detail in conjunction with the accompanying drawings. This is to enable those skilled in the art to more easily understand the advantages and features of the present invention, thereby more clearly defining the protection scope of the present invention.

[0012] Example 1: As shown in FIGS. 1 to 8, the self-seal strip with a tactile feedback function includes a self-seal strip 3 composed of a male end 1 and a female end 2. The male end 1 includes a male end carrier plate 11 and a rib 12 provided on the male end carrier plate 11. At least two sets of convex ribs are provided on the rib 12, and each set of convex ribs is symmetrically provided on both sides of the rib 12. The two sets of convex ribs are the first convex rib 121 and the second convex rib 122 respectively. A plurality of first grooves 124 are provided on the side of the male end carrier plate 11 away from the rib 12, and the rib 12 is further provided with protrusions 123 corresponding to the plurality of first grooves 124. Specifically, if the width of the first convex rib 121 is W1 and the second convex rib 122 is W2, the width W1 of the first convex rib 121 is narrower than the width W2 of the second convex rib 122. Referring to FIG. 3, in this embodiment, the first convex rib 121 and the second convex rib 122 are formed in a tower shape.

[0013] The female end 2 includes a female end carrier plate 21 and a cavity 22 provided on the female end carrier plate 21. The cavity 22 is fitted with the rib 12, and a second groove 23 for fitting with the plurality of protrusions 123 is further provided inside the cavity 22.

[0014] Example 2: As shown in FIGS. 1 to 8, the self-sealing strip with a tactile feedback function includes a self-sealing strip 3 composed of a male end 1 and a female end 2. The male end 1 includes a male end carrier plate 11 and a rib 12 provided on the male end carrier plate 11. At least two sets of convex ribs are provided on the rib 12, and each set of convex ribs is symmetrically provided on both sides of the rib 12. The two sets of convex ribs are the first convex rib 121 and the second convex rib 122 respectively. A plurality of first grooves 124 are provided on the side of the male end carrier plate 11 away from the rib 12, and a plurality of protrusions 123 corresponding to the plurality of first grooves 124 are further provided on the rib 12. Specifically, when the width of the first convex rib 121 is W1 and the width of the second convex rib 122 is W2, the width W1 of the first convex rib 121 is narrower than the width W2 of the second convex rib 122. In this embodiment, as shown in FIG. 6, the first convex rib 121 is much smaller than the second convex rib 122.

[0015] The female end 2 includes a female end carrier plate 21 and a cavity 22 provided on the female end carrier plate 21. The cavity 22 is fitted with the rib 12, and a second groove 23 for fitting with the plurality of protrusions 123 is further provided inside the cavity 22.

[0016] In all embodiments, the first groove 124 is not integrally formed but is subsequently press-formed. The first groove 124 is in a depressed position. Since the self-sealing strip is made of plastic, when it is depressed, a depression is generated to form the first groove 124, whereby the upper surface of the rib 12 is extruded to form the protrusion 123. By continuously pressing the protrusion 123 to generate a depression, the second groove 23 is formed. On the self-sealing strip, by continuously depressing at intervals, both the continuously spaced protrusions 123 and the second groove 23 can be formed. Of course, in actual manufacturing, due to changes in the depression position and other parameters, the protrusion 123 may not be centered and may be offset, but none of these will affect the use.

[0017] According to the above embodiments, in a sealed bag made of a self-sealing strip, a self-sealing strip 3 is provided at the opening of the sealed bag 5. Preferably, the sealed bag 5 further includes a seal strip 4. The seal strip 4 includes a male engagement strip 42 and a female engagement strip 41, and is sealed by the male engagement strip 42 fitting into the inside of the female engagement strip 41. Specifically, the seal strip 4 is arranged parallel to the self-sealing strip 3, and the distance between the seal strip 4 and the self-sealing strip 3 is H, and the distance H is 3 mm. In this embodiment, as shown in FIG. 5, the male engagement strip 42 is of an inverted hook type. Of course, in other cases, as shown in FIG. 4, the seal strip 4 may have the male engagement strip 42 in a mushroom type.
