ZIPPER BAG PRODUCING APPARATUS AND ZIPPER BAG PRODUCED USING THE SAMEFIELD OF THE INVENTION

[0001] The present invention relates to the field of engineering, and specifically relates to a zipper bag producing apparatus and a zipper bag produced using the same.BACKGROUND OF THE INVENTION

[0002] Nowadays, there is a zipper bag producing apparatus having main components including a melted plastic import section, a plastic sheet blow molding section, a plastic sheet rolling set, and a section for cutting and welding edges of a zipper bag, respectively. The plastic sheet blow molding section has a blowing head attached to it. This blowing head acts like a mold for molding a plastic sheet from melted plastic, and mainly comprises: a blowing head core, a blowing head jacket, a heart, a ring, a zipper plate, and a ring cover. In this case, the current blowing head ring has a smooth inner surface. Therefore, when the melted plastic is blown through the blowing head, a plastic sheet with a smooth surface will be obtained. In other words, a zipper bag with the smooth surface is obtained in the end. However, if there is a need to make a pattern on the zipper bag, it is necessary to add a process and apparatus specifically for making the pattern, which results in more time and cost in producing the zipper bag.SUMMARY OF THE INVENTION

[0003] This invention therefore aims to solve the above problem by providing a zipper bag producing apparatus comprising a melted plastic import section being an entrance to the zipper bag producing apparatus for melted plastic, a plastic sheet blow molding section located next to the melted plastic import section comprising a zipper ring section and a striped ring section with an inner diameter slightly larger than the zipper ring section, creating a plastic blowing channel therebetween, wherein the zipper ring section has at least one pair of male and female zipper structures arranged symmetrically apart with respect to the diameter and both zipper structures are connected to the above plastic blowing channel, a plastic sheet extrusion section located next to the plastic sheet blow molding section and having a plurality of rollers to roll out a cylindrical plastic sheet into a flat sheet while the plastic sheet is conveyed through the rollers, and a section for cutting and welding edges of a zipper bag, located next to the plastic sheet extrusion section, serving to weld edges of the zipper bag to leave an opening on only one side, and then cut the zipper bag apart, wherein the zipper bag producing apparatus is characterized in that the male and female zipper structures divide corresponding inner surfaces of the striped ring section into a short side ring and a long side ring between the two zipper structures and the striped ring section has at least one groove section formed on the long side ring of the inner surface of the ring.

[0004] As a result, when the melted plastic is blown through the groove sections on a ring of the blowing head, these groove sections create ridges on the plastic sheet resulting from a blowing process. The present invention therefore provides an apparatus capable of producing a patterned zipper bag through a single and pre-existing producing step and therefore there is no need to add specific processes and apparatus for pattern creation, which can prevent the extra time and cost of producing the zipper bag.

[0005] In one embodiment of the present invention, a zipper bag producing apparatus with more than one groove section on one part or distributed along the entire length of a long side ring, is provided. Therefore, this allows obtaining multiple patterns on a zipper bag at once, which can save more time and cost in creating patterns.

[0006] In one embodiment of the present invention, a zipper bag producing apparatus, wherein groove sections are on either half of a ring with respect to a diameter of the ring drawn through the center between two zipper structures, is provided. Therefore, it is possible to create a pattern on only one side of an outer surface of a zipper bag.

[0007] In one embodiment of the present invention, a zipper bag producing apparatus, wherein groove sections are distributed in such a way that the groove sections are formed in pairs on opposite sides with respect to a diameter of a ring drawn through the center between two zipper structures, is provided. Therefore, a symmetrical pattern can be created on an outer surface on both faces of a zipper bag.

[0008] In one embodiment of the present invention, a zipper bag producing apparatus, wherein groove sections are freely distributed along the entire length of a long side ring, is provided. Therefore, different patterns can be created along both surfaces of a zipper bag, creating a unique design feature.

[0009] In one embodiment of the present invention, a zipper bag producing apparatus, wherein groove sections are of a circular or rectangular shape or a combination thereof, is provided. Therefore, it is possible to obtain a rounded and rectangular embossed pattern with different textures depending on characteristics of the groove sections.

[0010] In one embodiment of the present invention, a zipper bag producing apparatus, wherein individual groove sections are all different sizes and shapes, or are partially the same size and shape, or are all the same size and shape, is provided. Therefore, this provides freedom to create a unique pattern on a zipper bag as required.

[0011] In addition, the present invention provides a zipper bag comprising a bag body having an internal space for containing objects, a bag end being an opening allowing objects to pass into an internal space of the bag, and a zipper assembly being constructed with zipper structures running the entire length of the zipper bag on an inner surface of the zipper bag between the bag body and the bag end, and wherein the zipper bag further comprises a plurality of ridges formed by groove sections of the apparatus obtained from the above embodiments of the present invention. Ridges can be on an outer or inner surface or both sides of the bag body. Therefore, the zipper bag with a desired pattern can be obtained without the need for a special pattern creation process, thus saving time and production costs.

[0012] In another embodiment of the present invention, the ridges of the above zipper bag are characterized in a straight stripe running horizontally the entire length of the zipper bag and parallel to the zipper. Thus, the zipper bag with a beautifully organized pattern can be obtained.BRIEF DESCRIPTION OF THE FIGURES

[0028] The present invention and various embodiments will be described herein with reference to the attached drawings.

[0029] As shown in, the zipper bag producing apparatus of the present invention mainly comprises the melted plastic import section 1, the plastic sheet blow molding section 2, the plastic sheet extrusion section 3, and the section for cutting and welding edges of the zipper bag 4.

[0030] The melted plastic import section 1 is characterized in a vertically arranged funnel-like structure that serves as a channel through which the melted plastic is fed into the zipper bag producing apparatus. After the melted plastic is fed through the melted plastic import section 1 into the zipper bag producing apparatus, the melted plastic is then conveyed to the plastic sheet blow molding section 2.

[0031] The plastic sheet blow molding section 2 is located next to the melted plastic import section 1 and has the blowing head 21 inside it. As shown in Figs. 2A and 2B, the blowing head 21 mainly consists of the blowing head core 201, the blowing head jacket 202, the heart 203, the zipper ring section 210, the striped ring section 220, the ring cover section 206, and the air blower section 207. In addition, the striped ring section 220 is arranged to have an internal diameter that is slightly larger than the zipper ring portion 210, forming the plastic blowing channel 230 therebetween. So that when the melted plastic is conveyed from the melted plastic import section 1 into the plastic sheet blow molding section 2 and the blowing head 21, the melted plastic is blown by the incoming air through the air blowing channel 207 and blown through the plastic blowing channel 230 according to the predetermined and controlled pressure. As a result, a cylindrical plastic sheet will be obtained with a thickness equal to the width of the plastic blowing channel 230 and a surface with a predetermined surface texture inside the plastic blowing channel 230. That is, the surface is characterized by the internal surface of the striped ring section 220 and the external surface of the zipper ring section 210 which form the plastic blowing channel 230 therebetween.

[0032] As shown in, the zipper ring section 210 has at least one pair of male zipper structure 211 and female zipper structure 212 (has a double zipper structure) arranged symmetrically apart on the surface of the zipper ring section with respect to its diameter. That is, based on the diameter along the vertical axis of the zipper ring section 210, the male zipper structure 211is arranged offset to the right at the same distance from said diameter as the female zipper structure 212 is arranged offset to the left. The male and female zipper structures 211, 212 are both connected to the plastic blowing channel 230 above, i.e., every zipper structure is arranged on the outer surface of the zipper ring section 210 and has a structure that extends into the interior of the zipper ring section 210 in a way that the base section of every zipper structure, which is on the outer surface, will be a gap opening to the plastic blowing channel 230 to allow the melted plastic to blow through along the zipper structures, resulting in both male and female zippers on the cylindrical plastic sheet. The zipper structures can be any shape that provide a male zipper and a female zipper that has a conformed structure and can be fastened together.illustrates an example of one type of the male and female zipper structures 211, 212, which will result in the male zipper with an arrow-like projection and the female zipper that embraces the male zipper and has a part that can be attached to the arrowhead of the male zipper.

[0033] In addition, as shown in the right side of, the male zipper structure 211 and the female zipper structure 212 of the zipper ring section 210 divide the corresponding inner surfaces of the striped ring section 220 into the short side ring 220A and the long side ring 220B between the two zipper structures 211, 212. The short side ring 220A is the ring of the striped ring section 220 where the zipper structures 211, 212 are closest to each other. The plastic sheet molded by the plastic blowing channel 230 located between these rings is the end of the zipper bag that will be cut off to form the top opening of the zipper bag, and the long side ring 220B is the ring of the striped ring section 220 where the zipper structures 211, 212 are furthest apart. The plastic sheet molded by the plastic blowing channel 230 between the rings is the zipper bag body with space inside for containing the object inside the zipper bag.

[0034] As shown in the right side of, the striped ring section 220 also has at least one groove section 221 formed on the long side ring 220B of the inner surface of the ring, i.e., on the inner surface of the striped ring section 220 adjacent to the plastic blowing channel 230 has a non-smooth surface throughout. However, on the long side ring 220B, there are the groove sections 221 formed on the inner surface and characterized as an opening towards the zipper ring section 210, so that when the melted plastic is blown through the groove sections 221, stripes are formed on the surface of the plastic sheet received, and are ultimately stripes on the surface of the zipper bag body obtained by the zipper bag producing apparatus of the present invention. In this case, the groove sections 221 may have different shapes, sizes and arrangements depending on the design. For example, they may be a set of square groove sections resembling gear teeth, or they may be curved in shape, may be small, large or a combination thereof, and may be arranged at any distance from each other, as will be explained later.

[0035] When the melted plastic is blown through the groove sections 221 located on the ring 220 of the blowing head 21, the groove sections 221 create ridges on the plastic sheet resulting from the blowing process. The present invention therefore provides the apparatus capable of producing the patterned zipper bag through a single and pre-existing producing step. As a result, there is no need to add specific processes and apparatus for pattern creation, which can prevent the extra time and cost of producing the zipper bag.

[0036] Next, as shown in, the zipper bag producing apparatus of the present invention also comprises the plastic sheet extrusion section 3 located next to the plastic sheet blow molding section 2. When the melted plastic is brought into the zipper bag producing apparatus through the melted plastic import section 1 and is blown into the cylindrical plastic sheet through the blowing head of the plastic sheet blow molding section 2, as described above, the cylindrical plastic sheet will be conveyed to the plastic sheet extrusion section 3. The plastic sheet extrusion section 3 comprises a plurality of rollers 301 that roll the cylindrical plastic sheet P into a flat sheet while the plastic sheet P is conveyed through the rollers 301. Then the flat plastic sheet is cut open by cutting off the part of the plastic sheet that is between the male and female zippers, i.e., the part of the plastic sheet molded by the plastic blowing channel 230 between the short side ring 220A, forming an opening for passage of objects into the zipper bag.

[0037] The plastic sheet, which is flat and has been cut open, then exits the plastic sheet extrusion section 3 and enter the section for cutting and welding edges of the zipper bag 4 of the zipper bag producing apparatus of the present invention. As shown in, the section for cutting and welding edges of the zipper bag 4 is located next to the plastic sheet extrusion section 3 and serves to cut each zipper bag apart according to the size of the zipper bag as set. Then the two edges of the zipper bag will be joined together to form the zipper bag having an internal space and an opening only on the top side of the zipper bag.

[0038] As described above, the striped ring section 220 of the zipper bag producing apparatus of the present invention has at least one groove section 221 molded on the long side ring 220B of the inner surface of the ring. In one embodiment of the present invention, there is provided the zipper bag producing apparatus where the striped ring section 220 has more than one groove section 221 on one part or distributed along the entire length of the long side ring 220B. For example, as shown in, the striped ring section 220 has more than one groove section 221 distributed along the entire length of the long side ring 220B. The groove sections 221, when viewed from above, have a semicircular shape in two sizes: small and large. Based on the horizontal diameter of, it can be seen that the upper half of the long side ring 220B above the horizontal diameter has the small groove sections 221, while the lower half of the long side ring 220B has the small groove sections 221on the right side of the vertical diameter and large groove sections on the left side, and two additional large groove sections on the right side. The distance between the two groove sections 221 on the upper half of the long side ring 220B is less than the distance between the two groove sections 221 on the lower half of the long side ring 220B. Thus, the striped ring section 220 with the groove sections 221 as shown inwill create a rounded stripe pattern (ridges 34) on both outer surfaces of the zipper bag body as shown in Figs. 9A and 9B. The rounded stripe pattern will have the size, arrangement and spacing between the stripes in accordance with the size, arrangement and spacing of the groove sections 221 of the striped ring section 220 of. That is, the upper half of the zipper bag body has small, evenly spaced, horizontal stripes while the lower half has long horizontal stripes, one side contains large stripes, the other side contains small stripes with a mixture of large stripes, wherein the stripes on both sides of the lower half are placed in corresponding positions. Thus, providing the zipper bag producing apparatus with more than one groove section on one part or distributed along the entire length of the above long side ring can provide multiple patterns on the zipper bag at once, which can save more time and cost in creating patterns.

[0039] In one embodiment of the present invention, there is provided the zipper bag producing apparatus wherein the groove sections 221 are distributed such that the groove sections 221 are formed in pairs on opposite sides with respect to the diameter of the ring 220 drawn through the center between the two zipper body structures.shows an example of the striped ring section 220 having the groove sections 221 according to the embodiment. The groove sections 221, when viewed from above, have a semicircular shape formed in two sizes: small and large. Based on the vertical diameter or diameter of the ring drawn through the center between the zipper body structures 211 and 212 of, it can be seen that the small groove sections 221 are arranged alternating with the large groove sections 221 along the circumference of the long side ring 220B. Meanwhile, the shape, size, arrangement and distance between the groove sections 221 on the left side of the vertical diameter are exactly the same as the groove sections 221 on the right side. The striped ring section 220 with the groove sections 221 as shown inwill create the rounded stripe pattern (ridges 34) on both outer surfaces of the zipper bag body. This pattern is characterized as a long stripe pattern, large and small, alternating all over the surface of the zipper bag body as shown in Figs. 10A and 10B. This pattern will also have the size, arrangement and spacing between the stripes in accordance with the size, arrangement and spacing of the groove sections 221 of the striped ring section 220 of. This will create a symmetrical and orderly patterned stripes on the outer surface on both sides of the zipper bag.

[0040] In addition, as shown in Figs. 7 and 8 where the groove sections 221 are distributed in such a way that the groove sections 221 are formed in pairs on opposite sides with respect to the diameter of the ring 220 drawn through the center between the zipper body structures 211 and 212. The groove sections 221 of the striped ring section 220 ofare characterized in a semicircular shape, of the same size, arranged next to each other on the left half of the striped ring section 220 with respect to the vertical diameter of one set and the other set on the right half, appearing to be mirror images of the groove sections 221 on the left half. This will create an identical and symmetrical, rounded stripe pattern on both sides of the outer surface of the zipper bag body, one set on each surface, in the center of the zipper bag as shown in Figs. 13A and 13B. In addition, the groove sections 221 of the striped ring section 220 ofare characterized in a semicircular shape, of the same size, arranged in sets, each set having three groove sections 221. On the left half of the striped ring section 220 with respect to the vertical diameter, there are five sets of these three groove sections arranged at approximately the same distance from each other. There are five more sets of the groove sections on the right half, which are mirror images of the five sets of the groove sections 221 on the left half. This will create an identical and symmetrical, rounded stripe pattern (ridges 34) on both sides of the outer surface of the zipper bag body. It comprises three parallel, longitudinal lines, five sets on each side, arranged with equal spacing between the sets as shown in Figs. 14A and 14B.

[0041] In one embodiment of the present invention, there is provided the zipper bag producing apparatus wherein the groove sections 221 are distributed in such a way that the groove sections 221 are on either half of the ring 220 with respect to the diameter of the ring drawn through the center between the zipper body structures 211 and 212. That is, instead of having the groove sections 221 on both the left and right halves with respect to the vertical diameter of the striped ring section 220, the groove sections 221 can also be provided on only the left or the right side to create a pattern on only one side of the outer surface of the zipper bag. In another embodiment of the present invention, the groove sections 221 are freely distributed along the entire length of the long side ring 220B, i.e., the groove sections 221 are arranged in an arbitrary position on the long side ring 220B. Therefore, different patterns can be created along both surfaces of the zipper bag, creating a unique design style and identity.

[0042] In one embodiment of the present invention, the groove sections 221 of this zipper bag producing apparatus may be in the circular or rectangular shape or a combination thereof, creating a pattern on the zipper bag that is rounded or rectangular or a combination thereof. Therefore, it is possible to obtain the rounded and rectangular embossed patterns with different textures depending on the characteristics of the groove sections 221. In addition, in another embodiment of the present invention, there is provided the zipper bag producing apparatus in which each of the groove sections 221 has a completely different size and shape, or some of the same size and shape as in Figs. 3 to 6, or are all the same size and shape as in Figs. 7 and 8. Therefore, this can provide freedom to create the unique pattern on the zipper bag as required.

[0043] In addition,andalso illustrate additional examples of the striped ring section 220 having the groove sections 221 of different sizes and arrangements in the zipper bag producing apparatus of the present invention, which can produce the zipper bag with different patterns as shown in Figs. 11A, 11B, and Figs. 12A, 12B, respectively.

That is, on one side of the zipper bag body, there are horizontal stripes (ridges 34) running horizontally on the upper half, with a set of small stripes running above a set of larger stripes. On the other side, there are horizontal stripes running horizontally on the lower half of the zipper bag body, with a set of small stripes running below a set of larger stripes.

[0045] illustrates six sets of the groove sections 221 of the striped ring section 220 consisting of two semicircular shaped sections of two sizes. Each set of groove sections 221 consists of groove sections 221 of the same size, creating a set of large groove sections and a set of small groove sections. The total of six sets of large grooves and small grooves are arranged alternately and at approximately the same distance on the surface of the striped ring section 220. The groove sections 221 as shown increates the pattern on the zipper bag as shown in Figs. 12A and 12B. That is, on one side of the zipper bag body, there are three sets of stripes (ridges 34) running horizontally with one smaller set of stripes in the center of the bag body between two larger sets of stripes arranged slightly away from the smaller sets. On the other side of the zipper bag body, there are also three sets of horizontal stripes, one large set in the center of the bag, between two smaller sets arranged slightly away from the large set. The stripe patterns on both sides of the zipper bag body are arranged in a consistent position with the stripe patterns on the opposite side.
