In modern logistics, the most widely used are packaging boxes (boxes). However, the conventional package does not provide the function of preventing collision and falling. That is, the packing box or case is thrown away during transportation or storage, easily causing deformation thereof, and thus possibly causing damage to or deformation of the packed item. Therefore, for some articles with high packaging requirements, such as electronic digital products, plastic ceramics, biochemical products, food and medicine, etc., it is necessary to provide a buffering function for the packaged articles to prevent the packaged articles from being damaged during transportation and storage.
The existing solution, such as the traditional paper packaging box, can be that the inside of the paper packaging box is filled with the buffering foam material to achieve the purpose of providing the buffering effect. However, the cost of shipping and storing such packages and filled cushioning foam is very expensive when it is shipped to the packaging site. And the buffering foam material pollutes the environment and is not environment-friendly.
In addition, the air buffer material can be filled in the paper packaging box, for example, after the packaged article is placed in the packaging box, the air buffer bag is stuffed in the packaging box, so that the packaged article is provided with a buffer effect. However, such an air-cushion bag is transported to a packing place separately from the packing box and is put into the packing box after being inflated in advance, so that it is inconvenient to use.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
Fig. 1 to 5 are schematic views illustrating a packing box with an air buffering function according to a preferred embodiment of the present invention, which can be used for storing various articles to be packed, such as electronic products, foods, medical products, chemical materials, biomaterials, plastic ceramics, fast consumer goods, and the like. Since the packing box has an air cushioning property, it is suitable for providing an air cushioning effect to the article to be packed.
In particular, the packet comprises at least one inflatable body 10, said inflatable body 10 being provided with at least one inflation valve 20, and a box 30. The inflatable body 10 is mounted to the inner surface of the case 30 to form an integral structure. The inflation valve 20 is used to inflate the inflatable body 10. The inflatable body 10 is used to provide an air cushion for the article to be packaged.
That is, the inflatable body 10 forms an inner structure of the packing box, and the box 30 forms an outer structure of the packing box. After the inflatable body 10 is inflated, the case 30 surrounds the outside of the inflatable body 10, thereby accommodating the inflatable body 10.
Thus, the packing box allows the inflatable body 10 and the box 30 to be transported together to a packing place for packing the article to be packed. The inflatable body 10 may not be inflated during transport and storage and may thus assume, for example, a compressed flat shape, thereby saving space for transport and storage. When the inflatable body 10 is used, the inflatable body 10 is inflated through the inflation valve 20 to reach a preset air pressure, and the expansion of the inflatable body 10 automatically drives the box body 30 to be formed, so that compared with the traditional packaging technology, the step of filling the inflatable cushion into a packaging paper box or a packaging paper box is not needed, and the packaging time is greatly saved.
It is worth mentioning that, when packaging, the article to be packaged can also be placed in the packaging box, and then the inflatable body 10 is inflated, when the inflatable body 10 is inflated and surrounds the article to be packaged, and during the inflation, the position can be automatically adjusted so that the inflatable body 10 tightly surrounds the article to be packaged, so that the article to be packaged can be stably held in the box 30 by the inflatable body 10 after the inflation is completed. In addition, when the inflatable body 10 is inflated, the cartridge 30 also applies pressure to the inflatable body 10 at the same time, so that the pressure can make the inflatable body 10 be more closely accommodated in the inflatable body 10 to form a compact structure.
The inflatable body 10 may be mounted on the inner surface of the case 30 by various mounting means. For example, by glue or other adhesive 40, to the inner surface of the box, the glue between the inflatable body 10 and the box 30 being able to adhere along a line of adhesion, or at some localized points, or in a whole area. It will be appreciated by those skilled in the art that other mounting means may be used to achieve this, for example, the inner surfaces of the inflatable body 10 and the case 30 are respectively provided with mating fastener elements such as velcro (velcro), etc.
Preferably, in this preferred embodiment of the present invention, said inflatable body 10 and said case 30 are glued together. And the adhesive force between the inflatable body 10 and the case 30 is strong enough not to peel off the inflatable body 10 from the case 30 when the inflatable body 10 is inflated. That is, the adhesive force between the inflatable body 10 and the cartridge 30 is greater than the pulling force between the inflatable body 10 and the cartridge 30 generated when the inflatable body 10 is inflated.
The case 30 may be made of various conventional materials, such as leather material, cloth material, paper material, etc. For example, in the preferred embodiment of the present invention, the case 30 may be a carton (carton) having a rectangular, square, polygonal, irregular, cylindrical shape, etc., and may have a single-layered structure or a composite structure of two, three, four, five or more layers. For example, the case 30 may include an inner paper on the inside, a middle medium paper, and an outer paper on the outside. The lining paper and the face paper can be tea board paper, kraft paper and the like. The core paper may be corrugated paper or the like. Wherein the corrugated paper can be provided with a plurality of layers, thereby being capable of resisting collision and falling in the process of carrying. The paper material of the box body 30 may be hard paper material or soft paper material, and the aspect of the present invention is not limited.
As shown in fig. 2 and 5, the case body 30 may be a three-ply structure including two layers of kraft paper 301 as liner paper and face paper and a middle interlayer of reinforcing ribs 302 according to a specific example of this preferred embodiment of the present invention. The kraft paper 301 is of a relatively light and soft material and a central interlayer of reinforcing ribs 302 may be held between the two layers of kraft paper 301 to prevent damage to the cassette body 30. Preferably, the rib sandwich 32 may include a plurality of ribs extending perpendicularly to each other, for example, a plurality of transverse ribs 3021 and a plurality of longitudinal ribs 3022. A plurality of the transverse reinforcing bars 3021 may be formed into a plurality of transverse reinforcing bar groups, a predetermined distance may be provided between adjacent transverse reinforcing bar groups, and a plurality of transverse reinforcing bar groups may be attached to the outer kraft paper 301 of the two kraft layers 301. Similarly, a plurality of the longitudinal reinforcing beads 3022 may be grouped into a plurality of longitudinal reinforcing bead groups, adjacent longitudinal reinforcing bead groups may have a predetermined distance therebetween, and the plurality of longitudinal reinforcing bead groups may be attached to the inner kraft paper 301 of the two kraft paper layers 301. In this embodiment, the stiffener sandwich 302 may be a gauze structure, which may include a plurality of yarns extending perpendicular to each other.
The housing 30 may be a six-sided rectangular structure having a main body 31 with four sides, which may be adhered to the inner surface of one side by an adhesive edge 311 disposed on the other side to form a hollow structure. The box 30 also comprises two end portions 32 and 33, such as a top end portion 32 and a bottom end portion 33, so that the box 30 forms a substantially rectangular receiving space 34 therein when the article to be packaged is packaged. The two ends 32 and 33 may each comprise four underseals, two of which are opposite each other, for snapping together. In this preferred embodiment, the bottom end 33 comprises four bottom seals 331, opposite each other two by two, extending from the main body 31 for mutual folding or snap-fitting together, so that the bottom opening thereof is sealable when the packet 30 is used for packaging the articles to be packaged, it being noted that in this preferred embodiment, the four bottom seals 331 may be glued together by means of an adhesive. The top end portion 32 defines a top end opening 34 for access to the item to be packaged, although the item to be packaged may be accessed or removed from its bottom opening. The tip portion 32 includes two foldable portions 321 that can be folded along a fold line 322 in the middle, and the two foldable portions 321 are provided on opposite sides, such as the left and right sides. The top portion 32 further includes two sealing portions 323 disposed on opposite sides, such as front and rear sides, of the box body 30. The two sealing portions 323 are pressed close to each other and bonded together by an adhesive, and the two foldable portions 321 are folded in half, so that the two sealing portions 323 and the two foldable portions 321 can seal the top end opening 34. It should be noted that the two sealing portions 323 and the two foldable portions 321 may integrally extend from the main body 31.
When not in use, the inflatable body 10 is not inflated, and the body 31 of the case 30 can be in a compressed state, i.e. the front and rear sides can be closely attached to each other, so that the overall package is very small in volume, has a compressed flat shape, and is suitable for storage and transportation. Upon inflation of the inflatable body 10, the expansion of the inflatable body 10 causes the box 30 to also be automatically shaped. The article to be packaged is then placed in the package 30, or it may be placed in the package before inflation. Then, the openings at both ends of the case body 30 are sealed as necessary, so that the entire packaging process is completed. It should be noted that the box body 30 may also be a self-sealing structure, i.e. after inflation, at least one of the top and bottom ends thereof may seal the opening automatically. In addition, depending on the application, the bottom end 33 of the box 30 may be pre-sealed before being inflated, i.e., the box 30 may have no bottom opening but only the top opening 34.
It is worth mentioning that the box 30 is generally of regular geometry, and after being arranged around the inflatable body 10, a plurality of the packets can be arranged neatly during transport and storage. That is, if the inflatable body 10 is used only to pack the article to be packed, the inflatable body 10 is not necessarily formed in a regular shape after being inflated, so that it is inconvenient to arrange and place it neatly when it is transported. In addition, the case 30 not only serves to protect the inflatable body 10 from damage caused by impact with a hard object, but also the case 30 can make the package more beautiful. The outer surface of the box body 30 can also be provided with company logo, artistic patterns, text advertisements and the like.
That is, the packing box of the present invention, in which the inflatable body 10 is combined with the box body 30, is constructed to make the packing process more time-saving and convenient, and is automatically formed when the inflatable body 10 is inflated; the inflatable body 10 is transported and stored as one body with the case 30, thus being low cost; and the inflatable body 10 provides an air cushioning effect; the case 30 serves to protect the inflatable body 10 and to apply pressure to the inflatable body 10 to firmly maintain the inflatable body 10 on the article to be packaged, and the case 30 serves to enhance the aesthetic appearance of the package. This is an effect that cannot be achieved by using the inflatable body 10 and the case 30 separately for packaging.
The inflatable body 10 may be attached to a partial position of the inner surface of the case 30, such as the inner surface of some sides, or may be attached to the inner surface of the case 30 in a surrounding manner, so that the inflatable body 10 forms a receiving space in the middle thereof for receiving the article to be packaged after being inflated.
Specifically, as shown in fig. 2 to 4, and fig. 7 to 10B, the inflatable body 10 includes at least one inflation unit 11, wherein the inflation unit 11 includes a first air chamber layer 101 and a second air chamber layer 102, which are overlapped with each other to form an inflation cavity 12 and are formed with at least one inflation port 13, and the inflation port 13 is communicated with the inflation cavity 12 for inflating the inflation cavity 12. As shown in the drawings, two or more inflation cells 11 are arranged side by side to form the inflatable body 10, wherein the inflation valve 20 is provided to each of the inflation cells 11. In other words, each of the inflatable cells 11 can be inflated independently, and an extended connecting seam 103 is formed between two adjacent inflatable cells 11, so that the inflatable chamber 12 can be divided into a plurality of separate inflatable chambers 12 by the connecting seams 103, and the connecting seams 103 can be formed by a heat sealing process. Thus, when one of the inflatable cells 11 is damaged and leaks air, the other inflatable cells 11 may not be affected. It is to be noted, of course, that the inflatable cells 11 may also be interconnected such that only one inflation valve 20 is required to inflate all of the inflatable cells 11. That is, the packing box having an air-cushioning property of the present invention can form a plurality of the air cells 11 by heat-sealing the first air cell layer 101 and the second air cell layer 102.
In addition, since the shape of each of the inflating units 11 can be changed after inflation, the inflatable body 10 can be made in various shapes and sizes. The inflatable cells 11 may be in the form of a strip (e.g., a transverse strip and/or a longitudinal strip, etc.), a block, etc., and the shape thereof is not limited, and in this preferred embodiment, the inflatable cells 11 may be formed in the form of a strip. In the preferred embodiment, the inflatable body 10 may further form an inflation channel 14, the inflation channel 14 is in communication with the inflation port 13 and is in communication with each of the inflation cells 11 through one or more of the inflation valves 20, such that when inflated from the inflation port 13, air enters the inflation channel 14, and the inflation channel 14 guides the air into the corresponding respective inflation valve 20, so that the air reenters the respective inflation cell 11. That is, the inflation passage 14 is an air distribution passage that distributes the air inflated from the inflation port 13 to the respective inflation cells 11. An inflation nozzle may be provided at the inflation port 13 to be connected to an inflation device such as an inflator to fill the packing box having an air cushioning property with air.
Each of the inflating cells 11 of the inflatable body 10 has a plurality of separating slits 104, respectively, such that each of the inflating cells 11 further forms a plurality of corresponding sub-inflating cells 111. It is worth mentioning that the separation slits 104 of the inflation units 11 are correspondingly positioned, that is, the inflatable body 10 has a plurality of rows of separation slits 104 arranged at intervals, and the separation slits 104 arranged at the plurality of inflation units 11 are arranged along a straight line, but are not continuous, so that a side wall is formed between two adjacent rows of the separation slits 104, thereby forming a plurality of side walls of the packing box with air cushioning property, and the side walls enclose a containing cavity for containing the to-be-packed article.
The number of the separation slits 104 of each of the inflation units 11 may be set as desired, that is, the number of the rows of the separation slits 104 of the inflatable body 10 may be varied so that the corresponding inflatable body 10 may have 3, 4 or more side walls. As shown in fig. 2 and 3, the packing box having an air cushioning property may be formed with a bottom wall, a circumferential wall around the bottom wall, and a top wall. It is worth mentioning that these separation seams 104 may be formed by a heat sealing process. It is possible to form the receiving cavity into various receiving spaces according to the number of the formed side walls.
In addition, the separation slits 104 do not separate the adjacent sub-inflatable cells 111, that is, at least one communication passage 112 is formed between the adjacent sub-inflatable cells 111, so that air enters each sub-inflatable cell 111 through the communication passages 112 when inflated. In the example shown in the drawings, the separation slits 104 formed by heat-sealing are provided at the central portions between the adjacent sub-inflatable cells 111, and the communication passages 112 are formed at both sides of the separation slits 104.
In this preferred embodiment of the present invention, the package having the air-cushioning property may include one inflatable body 10 which is formed into one air-packing device having the receiving chamber through a series of heat-sealing processes. In other embodiments, the packing box with air buffering capacity may be composed of two inflatable bodies 10, three inflatable bodies 10 or more inflatable bodies 10, whose ends are sewn to each other, thereby forming a packing device having the receiving chamber, and the present invention is not limited in this respect.
In this preferred embodiment of the present invention, the inflatable body 10 forms an air packing bag having one end closed and the other end opened. That is, it may have four peripheral walls and one bottom wall formed by the inflatable cells 11. At the top opening of the inflatable body 10, a plurality of the sub-inflating units 111 of opposite sides, such as left and right side walls, may be provided with one or more sealing seams 105, respectively, and the plurality of sealing seams 105 may be arranged to be spaced apart from each other. The sealing slits 105 may be arranged in parallel with the corresponding separation slits 104. The size of each of the sealing seams 105 may be smaller than that of the corresponding inflatable cell 11 so that the corresponding sub-inflatable cells 111 partially form an inflatable duct 114 to be inflated with gas, thereby having foldable cells 15 at the left and right sides thereof.
That is, since the air cells 11 located at the left and right sides of the position near the top opening of the air packing bag are partially inflated with respect to the front and rear sides thereof so as to be folded, the air cells 11 located at the front and rear sides can be brought close to each other after the packing is completed, so that the top opening of the air packing bag formed by the inflatable body 10 can be sealed.
The sub-inflating units 111 formed by the inflating units 11 may be arranged in the case 30 in the lateral direction or in the case 30 in the longitudinal direction. The outer wall of one or more of the sub-inflatable cells 111 is adhered to the inner surface of the case 30 by the adhesive 40. For example, the sub-inflating units 111 of the front and rear sides or at least one side of the air packing bag formed by the inflatable body 10 are adhered to the inner surface of the box body 30. Alternatively, the sub-inflator units 111 on the left and right sides are bonded to the inner surface of the case 30. Or the suture lines at the head and the tail of the inflatable body 10 are adhered to the inner surface of the box body 30 through the adhesive 40.
With respect to the case 30, when the case 30 has a generally rectangular configuration, it may be bonded to some of the parts of the outer surface of the inflatable body 10 by the inner surface of at least one of the four peripheral walls. For example, the two may be point bonded, line bonded, or surface bonded. Or may be bonded to the inner surface of the box 30 by some uninflated outer edges of the inflatable body 10. That is, the position of bonding is not limited, and the cartridge 30 and the inflatable body 10 may be bonded together in various conceivable ways.
As shown in fig. 6A and 6B, which are variant embodiments of the above preferred embodiment of the present invention, similarly, the packing box includes at least an inflatable body 10a, and a box body 30 a. The inflatable body 10a is mounted to the inner surface of the box 30a to form an integral structure, and the inflatable body 10a serves to provide an air cushioning effect to the article to be packaged.
In this preferred embodiment of the invention, the box 30a comprises a body 31a having four sides and divided into two groups, two opposite to each other. The box 30a has a top opening 34a and a bottom opening 35 a. The box body 30a has sealing structures 36a at both ends thereof for respectively sealing the top opening 34a and the bottom opening 35 a. Wherein the sealing structure 36a comprises a foldable flap 361a pivotally extending from one side, such as the rear side, of the main body 31a and a positioning flap 362a extending (e.g., vertically pivotally extending) from the foldable flap 361a, wherein the positioning flap 362a is adapted to be folded on the inner surface of the other side, such as the front side, of the main body 31a when sealing the opening, so that the foldable flap 361a is used for sealing the corresponding opening. A positioning groove 363a may be formed at a central position where the foldable piece 361a and the positioning piece 362a are connected, and a positioning tongue 364a may be integrally extended from the other side of the main body 31a, such as the front side, and the positioning tongue 364a is adapted to be inserted into the positioning groove 363a, thereby performing a snap-fit positioning function.
In addition, the sealing structure 36A may further include side flaps 365a respectively extending from the foldable sheet 361a, as shown in fig. 6A, and may be attached to the inner surfaces of the left and right sides of the main body 31a during sealing.
As shown in fig. 6B, the inflatable body 10a may have four peripheral walls 1001a formed by dividing the sub-inflating unit 111a obtained by the inflating unit 11a, a bottom wall 1002a extending between the four peripheral walls, and a movable top wall 1003 a. The movable top wall 1003a is used to seal the opening of the inflatable body 10a for accessing the item to be packaged.
As shown in fig. 6C and 6D, is another inflatable body 10b that may also be attached to the inside of the case 30 of the packing box of the present invention. The inflatable body 10b is formed with non-inflated portions at both outer sides of the plurality of the inflating units 11b, respectively, so that the non-inflated wings 15b can be formed at the corners thereof after the packing box having the air buffering performance is inflated. The uninflated flap 15b can be inserted into the receiving cavity of the package with air cushioning properties. The uninflated flap 15b is also formed with a receiving space which can be used to receive and attach to the bottom corner of the box 30 b. In addition, the top side of the inflatable body 10b, as shown in fig. 6D, has four sides having the inflating unit 11b disposed to face and the non-inflating portion 16b disposed to face. Since the uninflated portion 16b is provided, the other two sides provided with the inflating unit 11b may be folded downward to seal the opening of the packing box having the air-cushioning property. It is worth mentioning that the corresponding uninflated wings 15b and uninflated portions 16b of the present invention may instead be formed of small air cells having a plurality of small diameter air cells, which also provides a certain foldability of the portion of the package having air cushioning properties.
That is, if the size of the separation slits 104b on both sides of each of the sub-inflatable cells 111b of the uninflated flap 15b and the uninflated portion 16b is large enough, the corresponding sub-inflatable cell 111b can be completely sealed to become an uninflated cell. It is worth mentioning that after the packaging is completed, the uninflated unit formed by the uninflated portion 16b is folded inward so that the front and rear side walls are adjacent to each other, thereby sealing the top opening of the air-packing bag formed by the inflatable body 10 b.
As shown in fig. 6E and 6F, there are further embodiments of inflatable bodies 10c and 10d, which may also be installed inside the box body 10 of the packing box of the present invention, including four peripheral walls and a bottom wall, the inflatable body 10c in fig. 6E having a movable top wall for sealing the opening, and the movable top wall for sealing the opening in fig. 6F may not be provided.
Shown in fig. 6G is an additional embodiment of an inflatable body 10e which may also be mounted inside the box 30 of the package of the present invention. In this variant, the inflatable body 10e is sealed together end to end so as to be suitable for surrounding the article to be packaged, so that the inflatable body 10e can form a device for wrapping the perimeter of the article.
That is, the inflatable body 10e in this variant embodiment may not have top and bottom walls, but merely surround the periphery of the article to be packaged. The inflation cells 11e of the inflatable body 10e may have large-diameter cells and small-diameter cells, wherein the large-diameter cells and the small-diameter cells may be alternately arranged. For example, in the present modified embodiment, the small-diameter air cells are provided in the middle, and the large-diameter air cells are provided on both sides, so that the article to be packaged is adapted to be snapped in the position of the inflatable body 10e near the middle, while the large-diameter air cells function to tighten the openings on both sides to prevent the article to be packaged from slipping out.
Further, it is worth mentioning that the large-and-small-diameter air cells can be obtained by a method in which the large-diameter air cell can be provided with two or more inflation valves 20e, and the small-diameter air cell can be provided with only one inflation valve 20 e. Of course, the air chamber with the same size and diameter can be provided with only one inflation valve 20e, but the width and the size are different.
As shown in fig. 6H to 6J, another embodiment of the inflatable body 10f is provided, wherein when the sub-inflatable units 111f are obtained by partitioning the inflatable units 11f, a plurality of spaced-apart partition slits 104f are provided at one of the adjacent sub-inflatable units 111f adjacent to the opening of the inflatable body 10f, so that after inflation, one end of one sub-inflatable unit is pressed against one end of the other sub-inflatable unit formed by the adjacent sub-inflatable units 111f, as shown in fig. 6J, thereby functioning as a tightening opening.
It is worth mentioning that when the inflatable body 10f is mounted in the case 30 of the packing box and inflated, the case 30 applies pressure to the sub-inflating units 111f adjacent to the opening of the inflatable body 10f, so that it is easier to press one end of one of the sub-inflating units 111f adjacent to the other one to tighten the opening to prevent the item to be packed from sliding out of the packing box.
As shown in FIG. 6K, another embodiment of an inflatable body 10g is provided, which inflatable body 10g can be heat sealed by forming a plurality of air cells 111g at both ends thereof as side pressure air cells. And the outer air cells may be provided with heat seals 106g so that the two air cells do not inflate so that the inflatable body 10g can accommodate different regularity of the article to be packaged.
As shown in fig. 6L and 6M, the package may include two inflatable bodies 10h adhered to each other, in this embodiment, the inflating unit 11h of one inflatable body 10h is positioned right opposite to the connecting seam 103h of the other inflatable body 10 h. That is, the inflating units 11h of the two inflatable bodies 10h may be arranged in a staggered manner, so that the cushioning effect is enhanced. That is, when the inflatable body 10h of the inner layer is formed in the concave structure due to the connection seams 103h, the air cushioning effect is enhanced by the reinforcing effect of the inflating unit 11h of the other inflatable body 10h of the outer layer.
It is worth mentioning that this structure can also provide a thermal insulation effect, i.e. a two-layer structure, which makes it difficult for the outside to conduct heat through the connecting seam 103h through the staggered air columns, thereby effectively preventing heat exchange between the inside and the outside of the inflatable body 10 h.
It should be noted that while fig. 6A to 6M illustrate various alternative embodiments of the inflatable body 10, in practice, other alternative configurations are possible, provided that they provide an air cushion within the package.
As shown in fig. 7, the inflation valve 20 is a one-way valve including two sealing films 21 and 22 overlapped with each other and fixed between the two air cell layers 101 and 102 to form a four-layer structure, and an inflation passage 24 is formed between the two sealing films 21 and 22. Accordingly, when the air bag 10 is inflated, the two sealing films 21, 22 are bonded together to seal the inflation passage of the air bag, thereby sealing air in the inflation cavity 12 of the air bag 10, and when the air bag 10 includes a plurality of inflation cells 11, a plurality of inflation valves 20 are correspondingly provided in the respective inflation cells 11 to respectively seal air in the respective inflation cells 11. Specifically, the first sealing film 21 is overlappingly bonded to the first air cell layer 101, and the second sealing film 22 is overlappingly bonded to the second air cell layer 102. When the gas bag 10 is inflated, air is guided into the inflation channel 24 formed between the first sealing film 21 and the second sealing film 22. When the air bag is inflated, the first sealing film 21 and the second sealing film 22 are bonded to each other to seal the inflation channel 24 of the air bag. In addition, the air pressure in the air bag acts on the two sealing films 21 and 22, thereby ensuring that the two sealing films 21 and 22 are tightly bonded together to prevent air from leaking out of the air valve 20. That is, the gas valve is a one-way valve that only allows gas to enter the air bag 10 and prevents gas from back-permeating out.
The formation of the inflation channel 24 of the inflation valve 20 can be achieved by providing a blocking means between the two sealing films 21 and 22, and when the two sealing films 21 and 22 are heat-sealed to the two cell layers 101 and 102, the two sealing films 21 and 22 are not completely heat-sealed together because of the provision of the blocking means, thereby forming the inflation channel 24. In one particular example, the barrier may be a high temperature resistant ink.
Referring to fig. 8 to 10B, there is shown an air bag apparatus according to another embodiment of the present invention, which mainly illustrates the structure of another air valve 20A, the air valve 20A being a double check valve to provide a double sealing effect to the air bag. Wherein the air charge valve 20A includes a first packing film 21A, a second packing film 22A and a non-return packing film 23A.
The first sealing film 21A and the second sealing film 22A are overlapped between the first air cell layer 101A and the second air cell layer 102A of the inflator 11A. The first sealing film 21A and the second sealing film 22A are two thin flexible films made of plastic that are overlapped with each other. Preferably, the first sealing film 21A and the second sealing film 22A are the same two-layer film.
Each of the first sealing membrane 21A and the second sealing membrane 22A has a proximal edge extending to the inlet of the inflation valve 20A of the inflation unit 11A, and a distal edge extending to the interior of the inflation unit. Preferably, the borders of the proximal and distal edges of the first sealing film 21A and the second sealing film 22A are respectively contiguous.
In this embodiment, the near edge of the first sealing film 21A is bonded to the first chamber layer 101A. The proximal edge of the second sealing film 22A is bonded to the second air chamber layer 102A.
The non-return packing film 23A overlaps the proximal ends of the first packing film 21A and the second packing film 22A to form an inflation channel 24A between the first packing film 21A and the non-return packing film 23A and a non-return channel 25A between the non-return packing film 23A and the second packing film 22A.
The inflation channel 24A is arranged to inflate the inflation chamber 12A with air to fill the inflation cell 11A until distal ends of the first sealing membrane 21A and the second sealing membrane 22A are overlapped and sealed to close the inflation channel 24A by the air pressure within the inflation chamber 12A. According to the present preferred embodiment, when there is air leakage from between the distal ends of the first and second packing films 21A and 22A, as shown in fig. 10A and 10B, the air in the inflation chamber 12 is introduced into the check passage 25A to generate the supplementary air pressure, thereby further sealing the inflation passage 24A to compensate for the insufficient sealing effect of the first and second packing films 21A and 22A.
The inflation channel 24A has two open ends, one of which is formed at a proximal open end at a proximal edge of the first packing film 21A and the non-return packing film 23A. The other of which extends distally open to the distal edges of said first sealing membrane 21A and said second sealing membrane 22A for communication with said inflation lumen 12A. Compressed air may be directed into the plenum chamber 12A through the plenum channel 24A.
It is worth mentioning that when the inflation unit 11A is filled with air, the air pressure in the inflation chamber 12A applies pressure to the first sealing film 21A and the second sealing film 22A, thereby sealing the distal edges of the first sealing film 21A and the second sealing film 22A and sealing the distal open ends of the inflation channels 24A. In addition, the distal ends of the first sealing membrane 21A and the second sealing membrane 22A are sealed together due to surface tension.
The non-return sealing film 23A is a thin flexible film made of plastic. Preferably, the non-return packing film 23A, the first packing film 21A and the second packing film 22A are Polyethylene (PE) films. In addition, the thickness of each of the first air cell layer 101A and the second air cell layer 102A is larger than the thickness of each of the first sealing film 21A, the second sealing film 22A and the non-return sealing film 23A.
According to a preferred embodiment of the invention, the length of the non-return sealing film 23A is smaller than the length of each of the first sealing film 21A and the second sealing film 22A, so that when the non-return sealing film 23A overlaps the proximal ends of the first sealing film 21A and the second sealing film 22A, the distal ends of the first sealing film 21A and the second sealing film 22A overlap. It is worth mentioning that the length of the non-return sealing film 23A is defined as the distance between the proximal and distal edges of the non-return sealing film 23A. The length of each of the first sealing film 21A and the second sealing film 22A is defined as a distance between a proximal edge and a distal edge of the first sealing film 21A and the second sealing film 22A.
Accordingly, the proximal edges of the first and second packing films 21A and 22A and the proximal edge of the non-return packing film 23A are adjoined. In addition, the proximal edge of the non-return packing film 23A is bonded to the proximal edge of the second packing film 22A.
The non-return passage 25A is formed between the non-return packing film 23A and the second packing film 22A, wherein the non-return passage 25A has an open end facing the inflation chamber 12A and a closed end facing the air valve opening. In other words, the proximal end of the check passage 25A is the closed end and the distal end of the check passage 25A is the open end.
Accordingly, when air is filled into the check passage 25A at the open end, the check passage 25A is filled with air to generate supplementary air pressure, thereby further sealing the air filling passage 24A between the first packing film 21A and the second packing film 22A.
It is worth mentioning that when the inflation chamber 12A is inflated through the inflation channel 24A, the air flow direction in the inflation channel 24A is opposite to the air flow direction of the check channel 25A. Therefore, air does not fill the check passage 25A. When air leaks back from the inflation lumen 12A to the check passage 25A, air enters the check passage 25A to create supplemental air pressure to further seal the inflation passage 24A, thereby preventing air leakage. It is worth mentioning that the leaking air flows from the distal open end of the inflation channel 24A to the distal open end of the check channel 25A before leaking from the proximal open end of the inflation channel 24A, thereby avoiding air leakage. In addition, the non-return packing film 23A and the first packing film 21A are sealed together by surface tension to seal the inflation channel 24A.
To form the inflation valve 20A at the inflation unit 11A, the inflation valve 20A further includes a first sealing joint 201 to bond the first air cell layer 101A and the first sealing film 21A together at the air valve opening of the inflation unit 11A, and a second sealing joint 202 to bond the second air cell layer 102A, the non-return sealing film 23A and the second sealing film 22A together at the air valve opening of the inflation unit 11A.
Accordingly, the proximal edge of the first sealing film 21A is bonded to the first air chamber layer 101A through the first sealing joint 201. The proximal edges of the second air cell layer 102A and the second sealant film 22A, and the proximal edges of the non-return sealant film 23A are bonded together by the second sealing joint 202A. Preferably, two spaced sealing joints 201A are used to bond the first air chamber layer 101A and the first sealing film 21A, and two spaced second sealing joints 202A are used to bond the second air chamber layer 102A, the non-return sealing film 23A and the second sealing film 22A. It should be noted that the first sealing joint 201A and the second sealing joint 202A may be heat sealing lines, or may be heat sealing in other shapes such as crescent shape. In other words, the proximal edge of the first sealing film 21A and the first chamber layer 101A are heat sealed together by the sealing joint 201A. The proximal edges of the second air cell layer 102A and the second sealant film 22A, and the proximal edge of the non-return sealant film 22 are heat sealed together by the second sealing joint 202A.
In order to maintain a space between the first packing film 21A and the non-return packing film 23A after the heat-sealing process, the inflation valve 20A further includes a first heat-resistant object 26A formed between the first packing film 21A and the non-return packing film 23A to ensure the formation of the inflation passage 24A. The first heat-resistant object 26A serves to prevent the first sealing film 21A and the non-return sealing film 23A from being completely stuck together after the heat-sealing process.
Specifically, the first heat-resistant object 26A is provided at the proximal edge portions of the first packing film 21A and the non-return packing film 23A at the air valve opening of the inflation unit 11A, thereby ensuring that the proximal end of the inflation passage 24A is in an open state.
Also, in order to maintain the space between the second packing film 22A and the non-return packing film 23A after the heat-sealing process, the inflation valve 20A further includes a second heat-resistant object 27A formed between the second packing film 22A and the non-return packing film 23A to ensure the formation of the non-return passage 25A.
Specifically, the second heat-resistant object 27A is provided at the distal edge portions of the second packing film 22A and the non-return packing film 23A, thereby ensuring that the distal end of the non-return passage 25A is in an open state. It is worth mentioning that the proximal end of the non-return channel 25A is closed by the second sealing joint 202.
According to the preferred embodiment, the first heat-resistant object 26A and the second heat-resistant object 27A are two heat-resistant layers, which are coated on the respective corresponding films at predetermined positions to prevent the films from sticking together during the sealing process. The first heat resistant substance 26A extends on the proximal side of the non-return packing film 23A and faces the first packing film 21A. The second heat-resistant mass 27A extends on the opposite side of the distal end of the non-return sealing film 23A and faces the second sealing film 22A, wherein the second heat-resistant mass 27A is not arranged on the opposite side of the proximal end of the non-return sealing film 23A, so that the proximal end of the non-return channel 25A can be closed by the second sealing joint 202A. It is worth mentioning that the second heat-resistant object 27A not only prevents the non-return packing film 23A from adhering to the second packing film 22A to ensure that the distal end of the non-return passage 25A is in the open state, but also reinforces the action between the non-return packing film 23A and the first packing film 21A to close the inflation passage 24A due to surface tension.
The inflation valve 20A further comprises two lateral sealing joints 203A, which are two third sealing joints to bond the first sealing film 21A and the non-return sealing film 23A to form the side walls of the inflation channel 24A. The width of the inflation channel 24A is defined by the two lateral sealing joints 203A. Specifically, the two lateral sealing joints 203A are two inclined heat sealing lines, so that the width of the inflation channel 24A decreases from the air valve opening to each inflation cavity. In other words, the proximal open end of inflation channel 24A is a larger open end that communicates with the valve opening, while the distal open end of inflation channel 24A is a tapered open end and communicates with inflation lumen 12A. The tapered inflation channel 24A further prevents air from leaking from the inflation lumen 12A to the air valve opening.
Preferably, the lateral sealing joint 203A extends from a proximal edge of the first sealing membrane 21A and the second sealing membrane 22A to a distal edge thereof. Therefore, the lateral seal joint 203A is located at the proximal end portions of the first and second packing films 21A and 22A and the non-return packing film 23A are bonded together. The lateral sealing joint 203A is located at a distal end portion of the first sealing film 21A and the second sealing film 22A, and is bonded to the first sealing film 21A and the second sealing film 22A.
Accordingly, in order to inflate the inflation unit 11A, a pump pin is inserted into the inflation port 13A to inflate the compressed air into the inflation channel 24A, wherein the inflation direction of the air is from the proximal open end to the distal open end of the inflation channel 24A. So that the inflation unit 11A starts inflating. The air pressure of the inflation chamber 12A increases to expand the first and second air chamber layers 101A and 102A. At the same time, the air pressure acts on the first sealing film 21A and the second sealing film 22A, in particular on the distal ends of the first sealing film 21A and the second sealing film 22A. When the inflation unit 11A is completely filled with air, i.e., reaches a maximum filling amount, the air pressure in the inflation chamber 12A reaches a pressure sufficient to seal the distal ends of the first sealing membrane 21A and the second sealing membrane 22A to automatically seal the distal open ends of the inflation channels 24A. The prongs of the pump are now drawn away from the inflation port 13A.
When the distal ends of the first sealing membrane 21A and the second sealing membrane 22A are not completely sealed together, air in the inflation cavity 12A may leak into the inflation channel 24A. In order to avoid air leakage to the inflation channel 24A, the non-return packing film 23A is sealed with the first packing film 21A to seal the distal open end of the inflation channel 24A. Specifically, the intake direction of the check passage 25A is opposite to the inflation direction of the inflation passage 24A. In addition, when the open end of the check passage 25A is open, the distal open end of the inflation passage 24A is closed. Therefore, air enters from the open end of the check passage 25A and remains in the check passage 25A.
The check passage 25A is filled with air so that supplemental air pressure is created within the check passage 25A to further seal the inflation passage 24A. In particular, the distal open end of the inflation channel 24A between the first sealing film 21A and the non-return sealing film 23A is sealed. More specifically, the higher the supplemental air pressure in the check passage 25A, the better the sealing effect of the check packing film 23A. In other words, when air leaks from the inflation chamber 12A to lower the air pressure of the inflation chamber 12A, air enters the check passage 25A to increase the air pressure of the check passage 25A. Therefore, the total air pressure of the inflation pressure, i.e., the sum of the air pressures of the inflation chamber 12A and the check passage 25A, remains unchanged. Thus, air entering the check passage 25A from the inflation chamber 12A enters to enhance the sealing effect of the inflation passage 24A.
