Description

Technical Field

[0001] The present invention relates to the field of engineering, in particular to a zipper bag. Background Art

[0002] Typically, a zipper bag includes a bag body with an interior space defined by two walls and a closed bottom end. Items can be inserted into the interior space through an opening at the top of the bag body. A zipper, which can be opened and closed, is attached to the inner surfaces of both sides of the bag body's walls. A handle is located between the two walls of the bag body and the zipper. When the zipper is closed, the user must use both hands to pull the handles in different directions to open the zipper and place items into the bag through the opening. Alternatively, the user must use both hands to pull the handles in different directions to open the zipper and remove items from the bag.

[0003] However, in some cases, users need to open the zipper bag with one hand, rubbing the handle with their fingers to open the zipper. While many manufacturers have attempted to create linear patterns on the handle surface to generate friction when the user rubs the handle with their fingers, the friction generated by these patterns is generally not enough for the user to effectively rub the handle and open the zipper with one hand. Summary of the Invention

[0004] Therefore, the present invention aims to overcome the above problems by providing a zipper bag, which comprises: a bag body having an inner space formed by two walls and a closed end at the bottom, wherein articles can be inserted into the space through an opening at the top end of the bag body; a zipper comprising a male zipper attached to one inner wall of the bag body and a female zipper attached to the other inner wall and in the same plane as the male zipper; and a handle, which is a portion of the two walls of the bag body between the opening and the zipper, wherein the zipper bag is characterized in that the zipper bag has a raised portion protruding from the surface of the handle and extending from one edge of the handle to the other edge along a straight line parallel to the zipper, wherein the distance from the bottom of the raised portion to the top of the zipper is 7.5 mm to 8.5 mm. mm, and the raised portion includes: two first raised portions, located on the outer wall on the same side as the female zipper or the male zipper; two second raised portions, located on the inner wall on the same side as the first raised portions, the positions of the second raised portions relative to the first raised portions making the second raised portions receive the force applied to the first raised portions by the user's fingers; a third raised portion, located on the inner wall on the opposite side to the second raised portions and located between the plurality of second raised portions; and a fourth raised portion, located on the outer wall on the same side as the third raised portion, the position of the fourth raised portion relative to the third raised portion making the third raised portion receive the force applied to the fourth raised portion by the user's fingers.

[0005] As can be seen, when a user attempts to open a zipper bag with one hand, they use their index finger and thumb to pinch and squeeze the first and fourth raised portions, forcing the third raised portion to mate with the two second raised portions. As the user rubs the first and fourth raised portions and moves them in opposite directions, friction is generated between the second raised portions and the corresponding third raised portions. This friction is transmitted to the zipper through the bag's walls, ultimately pushing the male and female zippers apart. Furthermore, the distance of 7.5 to 8.5 mm from the bottom of the raised portion to the top of the zipper is an appropriate distance for transmitting friction from the raised portion to the zipper. Therefore, the present invention allows users to quickly and easily open a zipper bag with one hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0013] In an embodiment of the present invention, Figure 1 As shown in FIG, a zipper bag includes a bag body 1 having an interior space formed by two walls and a closed end at the bottom, wherein items can be inserted into the space through an opening 5 at the top end of the bag body 1; a zipper 2, comprising a male zipper 21 attached to one inner wall of the bag body 1, and a female zipper 22 attached to the other inner wall and in the same plane as the male zipper 21. A handle 3 is the portion of the two walls of the bag body 1 between the opening 5 and the zipper 2. In addition, the zipper bag also includes a raised portion 4 that protrudes from the surface of the handle 3 and extends from one edge of the handle 3 to the other edge along a straight line parallel to the zipper 2.

[0014] like Figure 2 As shown in FIG, the raised portion 4 is configured to protrude from the surface of the hand-held portion 3 and includes a protruding portion 22 and a protruding portion 21 (in this embodiment, the protruding portion 4 is configured to protrude from the surface of the hand-held portion 3 and include a protruding portion 22 and a protruding portion 21) located in the recessed position. Figure 2 Two first raised portions 41 are provided on the outer wall on the same side as the male zipper 21. Two second raised portions 42 are provided on the inner wall on the same side as the first raised portions 41. The positions of the second raised portions relative to the first raised portions 41 allow the second raised portions 42 to receive the force applied by the user's fingers to the first raised portions 41. A third raised portion 43 is provided on the inner wall on the opposite side from the second raised portions 42, and is located between the second raised portions 42. A fourth raised portion 44 is provided on the outer wall on the same side as the third raised portions 43. The position of the fourth raised portion relative to the third raised portion 43 allows the third raised portion 43 to receive the force applied by the user's fingers to the fourth raised portion 44.

[0015] When a user attempts to open the zipper bag with one hand, they pinch and squeeze the first and fourth raised portions 41 and 44 between their index finger and thumb. The second and third raised portions 42 and 43 receive the force from the user's hand and move toward each other until the third raised portion 43 enters the space between the two second raised portions 42. The user then rubs the first and fourth raised portions 41 and 44, causing them to move in opposite directions. This rubbing and moving action generates friction between the second raised portions 42 and the corresponding third raised portions 43. The user then rubs the first and fourth raised portions 41 and 44, pushing them in opposite directions. This rubbing and moving action creates friction between the second raised portions 42 and the corresponding third raised portions 43. The friction force is transferred to the zipper 2 through the wall of the bag body 1 and eventually pushes the male zipper 21 and the female zipper 22 apart.

[0016] According to the above structure and operation, since the raised portion 4 is provided on the handle 3, a greater direct force is generated on the zipper when opening the zipper bag. This allows the user to quickly and easily open the zipper bag with only one hand, even if the male and female zippers are separated.

[0017] In addition, if Figure 5As shown in FIG, the zipper 2 is composed of a male zipper 21 and a female zipper 22. The male zipper 21 is composed of a male zipper base 210 and a male engaging portion 211. The female zipper 22 is composed of a female zipper base 220 and a female engaging portion 221. The female zipper base and the female engaging portion are structurally consistent and compatible with the male engaging portion 211. Preferably, the distance B from the bottom of the raised portion (the second raised portion 42 in this embodiment) to the top of the zipper (the female engaging portion 221 in this embodiment) is 7.5 mm to 8.5 mm, and more preferably 8 mm.

[0018] As determined above, the distance B is a distance sufficient for transmitting the friction between the second raised portion 42 and the third raised portion 43 to the zipper 2 through the wall of the bag body 1 , allowing the user to quickly and easily open the zipper bag.

[0019] In addition, if Figure 5 As shown in , preferably, the distance A from the bottom of the raised portion to the top of the raised portion is 1.8 mm to 2.2 mm, and more preferably 2 mm. In this embodiment, the distance is the distance from the bottom of the second raised portion 42 to the top of the first raised portion 41.

[0020] As determined above, distance A is a distance suitable for transmitting the force of the user's hand through first raised portion 41 and fourth raised portion 44 and transmitting the force to second raised portion 42 and third raised portion 43, so that the second raised portion and the third raised portion move toward each other until third raised portion 43 enters the space between the two second raised portions 42. When the user rubs first raised portion 41 and fourth raised portion 44 and moves them in opposite directions, this generates sufficient friction between second raised portion 42 and third raised portion 43, and allows the user to open the zipper bag more quickly and easily.

[0021] Another embodiment of the present invention will now be described.

[0022] In another embodiment of the present invention, Figure 3 As shown in FIG, a zipper bag includes a bag body 1 having an interior space formed by two walls and a closed end at the bottom, wherein items can be inserted into the space through an opening 5 at the top end of the bag body 1; a zipper 2, comprising a male zipper 21 attached to one inner wall of the bag body 1, and a female zipper 22 attached to the other inner wall and in the same plane as the male zipper 21. A handle 3 is the portion of the two walls of the bag body 1 between the opening 5 and the zipper 2. In addition, the zipper bag also includes a raised portion 4 that protrudes from the surface of the handle 3 and extends from one edge of the handle 3 to the other edge along a straight line parallel to the zipper 2.

[0023] like Figure 4As shown in FIG, the raised portion 4 protrudes from the surface of the handle 3 and includes a position corresponding to the concave zipper 22 or the convex zipper 21 (in this embodiment, the convex zipper 21 is provided according to FIG. Figure 4 A first raised portion 401 is provided on the outer wall on the same side as the male zipper 21. A second raised portion 402 is provided on the inner wall on the same side as the first raised portion 401. The position of the second raised portion relative to the first raised portion 401 allows the second raised portion 402 to receive the force applied to the first raised portion 401 by the user's finger. A third raised portion 403 is provided on the inner wall on the opposite side from the second raised portion 402, and the third raised portion is located on a different plane from the second raised portion 402. A fourth raised portion 404 is provided on the outer wall on the same side as the third raised portion 403. The position of the fourth raised portion relative to the third raised portion 403 allows the third raised portion 403 to receive the force applied to the fourth raised portion 404 by the user's finger. That is, in this other embodiment of the present invention, there are a total of four raised portions, wherein the second raised portion 402 is positioned higher than the third raised portion 403 , that is, closer to the opening 5 of the bag body 1 than the third raised portion 403 .

[0024] When the user attempts to open the zipper bag with one hand, the user pinches and squeezes the first raised portion 401 and the fourth raised portion 404 with the index finger and thumb. The second raised portion 402 and the third raised portion 403 receive the force from the user's hand and move toward each other. The user then rubs the first raised portion 401 and moves it in a downward direction along the axis of the bag body 1 (according to the Figure 4 , moves in direction a), and moves in an upward direction along the axis of the bag body 1 (according to Figure 4 , pushing the fourth raised portion 44 in the direction opposite to direction a). This kneading and moving action generates friction between the second raised portion 402 and the third raised portion 403. This friction is transmitted to the zipper 2 through the wall of the bag body 1, and ultimately pushes the male zipper 21 and the female zipper 22 apart, causing them to separate.

[0025] According to the above structure and operation, since the four raised portions 401, 402, 403 and 404 are provided on the handle portion 3, this generates a greater direct force on the zipper when opening the zipper bag, and enables the user to quickly and easily open the zipper bag, i.e., unfasten the male zipper and the female zipper, using only one hand.

[0026] However, on the other hand, if the user of the zipper bag according to the present invention rubs the first convex portion 401 and moves it in an upward direction along the axis of the bag body 1 (according to Figure 4 , in the direction opposite to direction a) move; or, rub the fourth raised portion 404 and make it move in the downward direction along the axis of the bag 1 (according to Figure 4 , moving in direction b), there will be no friction between the second raised portion 402 and the third raised portion 403. Therefore, no friction is transmitted to the zipper 2 through the wall of the bag body 1, and therefore, the user cannot push the male zipper 21 and the female zipper 22 and separate them.

[0027] In addition, if Figure 6 As shown in FIG, the zipper 2 is composed of a male zipper 21 and a female zipper 22. The male zipper 21 is composed of a male zipper base 210 and a male engaging portion 211. The female zipper 22 is composed of a female zipper base 220 and a female engaging portion 221. The female zipper base and the female engaging portion are structurally consistent and compatible with the male engaging portion 211. Preferably, the distance B' from the bottom of the raised portion (the third raised portion 403 in this embodiment) to the top of the zipper (the female engaging portion 221 in this embodiment) is 7.5 mm to 8.5 mm, and more preferably 8 mm.

[0028] As determined above, the distance B' is sufficient to transmit the friction between the second raised portion 402 and the third raised portion 403 to the zipper 2 through the wall of the bag body 1, allowing the user to quickly and easily open the zipper bag.

[0029] In addition, if Figure 6 As shown in , preferably, the distance A' from the bottom of the raised portion to the top of the raised portion is 1.2 mm to 1.6 mm, and more preferably 1.4 mm. In this embodiment, the distance is the distance from the bottom of the third raised portion 403 to the top of the second raised portion 402.

[0030] As determined above, distance A' is a distance suitable for transferring the force of the user's hand through first raised portion 401 and fourth raised portion 404 and transferring this force to second raised portion 402 and third raised portion 403, causing them to move toward each other. When the user rubs first raised portion 401 and fourth raised portion 404, moving the first raised portion in direction a and the fourth raised portion in the opposite direction, this generates sufficient friction between second raised portion 402 and third raised portion 403, allowing the user to open the zipper bag more quickly and easily.

[0031] In addition, if Figure 5 and Figure 6 As shown in FIG, preferably, the thickness C and C' of the bag wall at the position between the zipper 2 and the raised portion 4 is 0.10 mm to 0.12 mm, preferably 0.11 mm.

[0032] In addition to the various embodiments described in detail herein, modifications can be clearly understood and made by those skilled in the art of zipper bags to obtain a zipper bag that allows a user to quickly and easily open the zipper bag with one hand. For example, within the scope and intent of the present invention as shown in the appended claims, in the following examples, Figure 2 In the case of the zipper bag shown in , it can be arranged so that the first convex portion 41 and the second convex portion 42 are located on the same side as the female zipper 22, and the third convex portion 43 and the fourth convex portion 44 are located on the same side as the male zipper 21; or, in the case of the zipper bag shown in Figure 4 In the case of the zipper bag shown in , it can be arranged so that the first and second raised portions 401, 402 are on the same side as the female zipper 22, and the third and fourth raised portions 403, 404 are on the same side as the male zipper 21, etc.
