Definitions

  • the present invention relates to a nonlinear air stop valve structure, in particular to an air stop valve used in an air sealing body capable of reducing the backflow of air, an inner membrane of the air stop valve, as well as an air inlet, an air outlet, an arc and a breach of the inner membrane.
  • an air sealing body includes an airbag for packaging and an airbag for shock absorption
  • present existing air sealing bodies usually come with a one-way air stop valve for inflating the air sealing bodies, such that the air sealing body can lock the air automatically after the air sealing body is inflated through the air stop valve.
  • the conventional air sealing body is developed into a product with a continuous one-way air stop valve and installed to a continuous air column, such that each independent air column can be fully inflated by a one-time inflation, and after air is passed through the air stop valve, the air is locked into the air sealing body, and the continuous one-way air stop valve is introduced to bring the inflatable air column to industrial applications and become a buffering package for products.
  • the continuous one-way air stop values of this sort can be applied for transportations or in warehouses as disclosed in Pat. Pub. No. US 2007/0267094 A1 and U.S. Pat. Application No. 10/610,501 .
  • the aforementioned structure also has a serious drawback, since the one-way air stop valve can lock air, but the capability of locking air in the air columns of the air sealing body cannot last too long. In other words, such one-way air stop valve is unable to block and prevent air in the air column from circulating and entering into the original path of the air columns and flowing back into the atmosphere, so that the air in the air columns of the air sealing body will flow to the outside slowly and unconsciously. As a result, the air in the air sealing body will be discharged to lose the buffering function.
  • a one-way air stop valve adopts a hot structure with an arrow-shaped hot sealing pattern formed at a lower end of the one-way air stop valve, so that a gas enters from the arrow-shaped pattern into the air sealing body. If the gas flows back, the gas is blocked by the arrow-shaped pattern, but the diversion positions are still linear. In other words, a straight-line channel is formed, causing a backflow of the gas in the air sealing body.
  • an air stop valve with a linear blocking structure wherein a cross design is adopted, and a breach is reserved at an end of the linear path to let air enter from the breach into the next level, and the air at the level is blocked immediately to drive the air to switch its direction to move to the breach at the other end.
  • the purpose is to block any air flowing backing in a reverse direction into the breach, so as to make the backflow difficult and achieve a good air stopping effect.
  • the structure adopts a linear blocking and a turning which violates the theory of fluid dynamics. As a result, the inflation operation will be very unsmooth.
  • the present invention provides a nonlinear air stop valve structure, with two narrower plastic inner membranes disposed in two wider plastic outer membranes, and assembled in an air sealing body, comprising: a plurality of arcs, formed on the inner membrane by a hot sealing, and disposed on both sides of the inner membrane respectively, and comprising a plurality of left arcs disposed on a side of the inner membrane, and a plurality of right arcs disposed on the other side of the inner membrane, and the left arcs and right arcs being arranged symmetrically on left and right sides, and the left arc and the right arc having a breach formed at an end-point of the left arc and the right arc and disposed adjacent to a concave arc surface of the arc on the other side, and plural groups of left and right arcs being arranged on left and right sides from the top to the bottom to form a nonlinear air stop valve structure.
  • the air in the sealing body flows back along the inlet path of the air stop valve, the air is blocked and guided by the left and right arcs and divides the backflow of air, such that a very small quantity of air flowing back to the air inlet, so as to achieve the effect of preventing the backflow of air without causing difficulties or unsmooth operations, and the invention can maintain a good buffering condition of the air sealing body.
  • the inner membrane has a heat resisting material coated at a predetermined position of an air inlet formed on an inner side of any inner membrane, such that after the inner membrane is placed into the outer membranes and thermally sealed with the horizontal hot sealing line, the inner side of the inner membrane at the position of the heat resisting material is not thermally sealed or coupled to form an air inlet of the sealing body, and air passes through the air inlet and circulates along the left and right arcs and flows all the way to the air outlet formed at the bottom of the inner membrane to enter into the sealing body, when the sealing body is inflated.
  • a flow guide passage is formed between the upper and lower arcs for guiding back flowing air, and a lower end of the arc is used as a natural block when the air flows back, so that the back flowing air is blocked by the lower end of the arc, and the flow guide passage guides the blocked air accordingly into a sealed space, and the blocking and air guiding effects of the left and right arcs prevent a gas or air stored in the sealing body from flowing back to the original air inlet and prevent a backflow, so that the sealing body can maintain a long air-lock time to assure a buffering capability of the sealing body.
  • the flow guide passage has a hot-sealing length extended to a boundary of the sealed space, so that the sealed space is partitioned into a plurality of independent sealed chambers, and gas guided from the flow guide passage will not be overlapped or interfered with one another.
  • the inner membrane and a single outer membrane of the sealing body are hot sealed with the arc in advance to form a seal between the air stop valve and the outer membrane, and after the sealing body is inflated, there is no internal expansion, thus an internal pressure is produced to compress the air stop valve to define an air stop and improve an air stopping effect.
  • the air stop valve is installed independently between the outer membranes, and after the sealing body is inflated, an internal pressure of the sealing body increases due to the expansion of air, so that both sides of the air stop valve are pressed to form an air stop to improve an air stopping effect.
  • An air route from the air inlet to the air outlet is formed between the left arc and the right arc, and the air route is used together with a conventional linear method by a nonlinear method, and the air route is used together with an upper section, or both upper and lower section as needed.
  • the sealing body comprises at least one air chamber formed therein and disposed between the outer membranes, and each air chamber comprises an air inlet, and the left and right arcs coupled to the air inlet and the air inlet hot sealing line of the heat resisting material are coupled closely with one another to prevent the air flowing back from a joint of the air inlet and the left and right arcs to an inflating channel of the sealing body to leak from the sealing body.
  • the quantity of arcs arranged at the top and bottom and the spacing between the arc and the breach are determined according to actual requirements.
  • the air stop valve is used separately, or installed continuously on a continuous air column type air sealing body for its use, and when an inflating channel of the continuous air column type air sealing body is inflated, the air inlet of the continuously installed air stop valve can be opened automatically, and the inner membrane further includes a heat resisting material extended to the inflating channel and a hot-sealing node on the heat resisting material is formed between the inner membrane and the outer membranes in advance, and since the inner side of the inner membrane is coated with the heat resisting material, therefore the inner side of the inner membrane is not adhered during a hot sealing, and the inner membrane and the outer membranes coupled to the inner membrane are adhered by the hot sealing, and when the inflating channel is inflated and expanded, the outer membranes are spread outwardly to pull both of the outer membrane and the inner membrane outwardly, so as to naturally inflate the inflating channel and automatically pull open the inner membrane and the air inlet.
  • the inflating channel of the continuous air column type air sealing body does not have any hot-sealing node but uses an inflating channel instead, and two inner membranes and two outer membranes of the air column adjacent to the air inlet are hot sealed to form a hot-sealed block, such that when the inflating channel is inflated, the hot-sealed block does not inflate or expand, the inflating channel with no hot-sealed block is expanded or contracted due to inflation to drive the two hot-sealed blocks to compress the air inlet to open the air inlet automatically.
  • the present invention further comprises the left and right arcs asymmetrically arranged, and the top and the bottom of the arc are connected all the way to the bottom of the inner membrane to form a sealed air route.
