Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of bags, and in particular to a zipper assembly and a sealing bag.

BACKGROUND

[0002] Sealing bags have the characteristics of easy opening and good sealing effect, and are widely used in life. The existing sealing bag mainly includes a body, a slider and a zipper. The slider is provided with an opening tongue, and the zipper includes two parallel single chains. Each chain is provided with several parallel hooks, and when the slider slides along the zipper, the hooks on the two single chains are engaged with each other. The traditional sealing bag has no reminder function. When the slider slides along the zipper, it is difficult to judge whether the hooks on the two single chains have already been engaged with each other. Meanwhile, the opening tongue in the existing sealing bag either protrudes into the upper part of the two hooks and is not inserted between the hooks, or is inserted between the two hooks. In case that the opening tongue is inserted into the upper part of the two hooks and not inserted between the hooks, when the slider slides along the zipper to open the zipper, the two hooks are not easy to be disengaged from each other as they are tightly engaged with each other, while when the opening tongue is completely inserted between the two hooks, the sealing effect may be poor.

DETAILED DESCRIPTION

[0017] In order to illustrate the idea and purpose of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] In the first embodiment, as shown in FIG. 1 to 6, a zipper assembly, including a zipper 20 and a slider 10 configured for opening and closing the zipper 20, wherein the slider 10 includes an opening tongue 11, the slider 10 is slidably connected to the zipper 20, and the zipper 20 is pressed to close or separated by pulling the slider 10; the zipper 20 includes two single chains 21, and each of the single chains 21 is provided at an inner side with at least an upper complementary sealing part 24 and a lower complementary sealing part 25 which are arranged side by side. The upper complementary sealing parts 24 include a first secondary hook 241 and a first primary hook 242, which are matched with each other. An inner side of the first secondary hook 241 or the first primary hook 242 is provided with first bumps 243, a first groove 244 is provided between every two adjacent first bumps 243, a head 111 of the opening tongue 11 is inserted between the first secondary hook 241 and the first primary hook 242, and left and right sides of the head 111 of the opening tongue 11 respectively abut against the first bumps 243 which are arranged opposite to each other. The slider 10 is pulled to move forwards and backwards, and the left and right sides of the head 111 of the opening tongue 11 respectively collide with the first bumps 243 and cross the first grooves 244, such that the slider 10 makes a sound during movement thereof.

[0019] As shown in FIG. 1 to 6, the special structure of the first secondary hook 241 or the first primary hook 242 is to provide first bumps 243, the inner sides of the first secondary hook 241 and the first primary hook 242 can both be provided with the first bumps 243, which collide with the head 111 of the special opening tongue 11 to make a special sound so as to achieve a prompting function, and when the sound stops, sealing is complete. The distance between the adjacent first bumps 243 is constant so that the sound is special and dense. When the head 111 of the opening tongue 11 is pulled, the first bumps 243 collide with the head 111 of the opening tongue 11 to make a sound.

[0020] As shown in FIG. 1 to 6, the head 111 of the opening tongue 11 is of a tapered structure, and the head 111 of the opening tongue 11 is inserted into the pair of upper complementary sealing parts 24 close to the cavity 22. When the slider 10 slides along the zipper 20 to open the zipper 20, the head 111 cuts the upper complementary sealing parts 24 and drives the lower complementary sealing parts 25 to open, so that the whole zipper 20 is opened. When the slider 10 slides along the zipper 20 to close the zipper 20, although the head 111 is inserted into the upper complementary sealing parts 24, the lower complementary sealing parts 25 are still in a state of mutual fastening, so as to have a good sealing function. Meanwhile, as only the head 111 is inserted into the upper complementary sealing parts 24 and the volume of the head 111 is relatively small, when the slider 10 slides along the zipper 20 to close the zipper 20, the slider 10 is located at one end of the zipper 20, a portion of the upper complementary sealing parts 24 close to the end, which has a small volume, is in an unfastened state, and the remaining portion of the upper complementary sealing parts 24 is all in a fastened state.

[0021] As shown in FIG. 1 to 6, the lower complementary sealing parts 25 include a second secondary hook 251 and a second primary hook 252, which are matched with each other. When the slider 10 slides towards a closed end of the zipper 20, the first secondary hook 241 and the first primary hook 242 are engaged with each other, and the second secondary hook 251 and the second primary hook 252 are engaged with each other. When the slider 10 slides toward an open end of the zipper 20, the first secondary hook 241 and the first primary hook 242 are disengaged from each other, and the second secondary hook 251 and the second primary hook 252 are disengaged from each other.

[0022] As shown in FIG. 1 to 6, the first secondary hook 241 and the second secondary hook 251 are oriented in a same direction, and the first primary hook 242 and the second primary hook 252 are oriented in a same direction; the first secondary hook 241 and the first primary hook 242 are arranged opposite to each other, and the second secondary hook 251 and the second primary hook 252 are arranged opposite to each other. The first secondary hook 241 and the second secondary hook 251 are in the same structure, and the first primary hook 242 and the second primary hook 252 are in the same structure.

[0023] As shown in FIG. 1 to 6, a slider limit bar 211 is provided on an outer side of a bottom of each of the single chains 21; a respective limit block 121 is arranged on an inner side of a bottom of each of two limit pieces 12. When the slider 10 is slidably connected to the zipper 20, each of the slider limit bars 211 is clamped on an inner side of the respective limit block 121 and slidably connected to the respective limit block 121. When the slider 10 is slidably connected to the zipper 20, each of the slider limit bars 211 is clamped on an inner side of the respective limit block 121 and slidably connected to the respective limit block 121. The slider limit bar 211 limits the slider 10 to prevent the slider 10 from separating from the zipper 20.

[0024] In the second embodiment, as shown in FIG. 1 to 6, the difference between the present embodiment and the first embodiment lies in that: the slider 10 further includes two limit pieces 12 and a connecting block 13, and the two limit pieces 12 are arranged in parallel. The opening tongue 11 is located between the two limit pieces 12 and connected to the connecting block 13. Inner sides of the two limit pieces 12 are provided with closing bars 122, the two single chains 21 pass through an area enclosed by the two limit pieces 12 and the connecting block 13. An outer side of the zipper 20 is provided with second bumps 26, a second groove 27 is provided between every two adjacent second bumps 26, and the two closing bars 122 of the opening tongue 11 respectively abut against the second bumps 26 which are arranged opposite to each other. When the slider 10 is pulled to move forwards and backwards, and the closing bars 122 collide with the second bumps 26 and cross the second grooves 27, such that the slider 10 makes a sound during movement thereof. The outer side of the zipper 20 is provided with the second bumps 26, the closing bars 122 collide with the corresponding second bumps 26 to make a special sound so as to achieve a prompting function, and when the sound stops, sealing is complete. The distance between the adjacent second bumps 26 is constant so that the sound is special and dense. When the head 111 of the opening tongue 11 is pulled, the second bumps 26 collide with the closing bars 122 to make a sound.

[0025] In the third embodiment, as shown in FIG. 1 to 6, the difference between the present embodiment and the first embodiment or the second embodiment lies in that: a guiding part 23 is provided on an inner side of a top of each zipper 20; a tail 112 of the opening tongue 11 is located in a cavity 22 enclosed by the two guiding parts 23 and the two upper complementary sealing parts 24 adjacent to the guiding parts 23. The guiding parts 23 are each provided with third bumps 231 on respective inner walls opposite to each other, a third groove 232 is provided between every two adjacent third bumps 231, and the tail 112 of the opening tongue 11 abuts against the third bumps 231 which are arranged opposite to each other. When the slider 10 is pulled to move forwards and backwards, both sides of the opening tongue 11 respectively collide with the third bumps 231 and cross the third grooves 232, such that the slider 10 makes a sound during movement thereof. The special structure of the inner walls of the cavity 22 is to provide the third bumps 231, which collide with the tail 112 of the special opening tongue 11 to make a special sound so as to achieve a prompting function, and when the sound stops, sealing is complete. The distance between the adjacent third bumps 231 is constant so that the sound is special and dense.

[0026] As shown in FIG. 1 to 6, the head 111 and the tail 112 of the opening tongue 11 are in an integral structure, with the opening tongue 11 gradually decreasing in width from the tail 112 to the head 111 and gradually increasing in height from the tail 112 to the head 111. The opening tongue 11 includes the head 111 and the tail 112, with the tail 112 being located in the cavity 22 and the head 111 being inserted into the pair of upper complementary sealing parts 24 close to the cavity 22; when the slider 10 slides along the zipper 20 to open the zipper 20, the head 111 cuts the upper complementary sealing parts 24 and drives the other lower complementary sealing parts 25 to open, so that the whole zipper 20 is opened; when the slider 10 slides along the zipper 20 to close the zipper 20, the tail 112 is located in the cavity 22, and although the head 111 is inserted into the upper complementary sealing parts 24, the other lower complementary sealing parts 25 are still in a state of mutual fastening, so as to play a very good sealing role. Meanwhile, as only the head 111 is inserted into the upper complementary sealing parts 24 and the volume of the head 111 is relatively small, when the slider 10 slides along the zipper 20 to close the zipper 20, the slider 10 is located at one end of the zipper 20, a portion of the upper complementary sealing parts 24 close to the end, which has a small volume, is in an unfastened state, and the remaining portion of the upper complementary sealing parts 24 is all in a fastened state.

[0027] As shown in FIG. 1 to 6, the head 111 and the tail 112 are in an integral structure, with the opening tongue 11 gradually decreasing in width from the tail 112 to the head 111 and gradually increasing in height from the tail 112 to the head 111. The width of the head 111 is small, which is favorable for cutting the upper complementary sealing parts 24. Meanwhile, due to the small width of the head 111, the volume of the head 111 inserted into the upper complementary sealing parts 24 is small, and when the slider 10 slides to the closed end of the zipper 20, the upper complementary sealing parts 24 are fastened to each other and the lower complementary sealing parts 25 are fastened to each other, with only a small portion of the upper complementary sealing parts 24 being separated by the head 111, and the rest being fastened. Thus, a sealing effect is obtained, and the zipper 20 can be opened very well.

[0028] In the fourth embodiment, as shown in FIG. 1 to 7, a sealing bag is provided, including a body 30 and further including sealing ribs 40 and the zipper assembly, wherein the zipper assembly is arranged at an opening of the body, and the sealing ribs 40 are arranged at the opening of the body and located at a lower side of the zipper assembly; the sealing ribs 40 include a convex rib 41 and a concave rib 42, which are respectively provided on both sides of the opening of the body. When the opening of the body is sealed, the convex rib 41 and the concave rib 42 are tightly clamped to form a reliable seal.

[0029] As shown in FIG. 7, the convex rib 41 is in an arrow-shaped convex angle structure, and the concave rib 42 is a hook-shaped slot, and when the opening of the body is sealed, the convex rib 41 and the concave rib 42 are tightly clamped to each other. The sealing ribs 40 can be used to further increase the sealing effect of the sealing bag.

[0030] In the fifth embodiment, as shown in FIG. 1 to 6 and 8, a sealing bag is provided, including a body 30 and further including sealing ribs 40 and the zipper assembly, wherein the zipper assembly is arranged at an opening of the body, and the sealing ribs 40 are arranged at the opening of the body and located at a lower side of the zipper assembly; the sealing ribs 40 include two toothless hooks 51 which are arranged side by side, and the two toothless hooks 51 are correspondingly disposed on both sides of the opening of the body 30 and are matched with each other. Each of the toothless hooks 51 is disposed on one side of the inner wall of the body 30, and the two toothless hooks 51 are arranged opposite to each other, when the opening of the body 30 is sealed, the two toothless hooks 51 are tightly clamped to form a reliable seal.

[0031] As shown in FIG. 1 to 6 and 8, the hooks of the toothless hooks 51 located on the same side of the inner wall of the body 30 are oriented in a same direction. After the toothless hooks 51 are sealed with each other, the sealing effect of the sealing bag can be further increased.

[0032] The above are the specific embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and modifications can also be made without departing from the principles of the present invention.
