Description

Buffer jacket with internal folding column hammock

The present invention relates to a cushioning sheath, and more particularly to a cushioning sheath having an inner folded air column hammock that can be quickly inflated and has an inner fold suspension structure.

With the rapid development of the technology industry, the construction of electronic and communication products is becoming more and more sophisticated, such as smart phones, tablets or flat-panel LCD TVs. In contrast, in order to ensure that the goods are not packed or transported in the back-end delivery process. Damage to internal items plays an important role in the packaging and containment of the product. Traditional early protection packaging materials use a soft substance such as foam to be placed in a box to provide a shock-absorbing cushioning effect, but the effect is very limited and the foam cannot be evenly placed, and it is more likely to be scattered around.
In order to overcome the aforementioned shortcomings, the manufacturer has developed an air jacket for filling an inflatable body as a package shockproof material. The inflatable body has a body shape and has a plurality of air columns, and the inflatable body can be placed around the article or the package, but only It can provide protection for the single face of the article. In other words, it is necessary to put a plurality of air jackets at the same time to achieve the perfect anti-shock buffer effect. However, the process of placing multiple air jackets is quite troublesome, and the air jackets between the pieces are It is not fixed and easy to displace. Moreover, the traditional air sleeve is filled with a film inflated, and it directly abuts against the container. Once the container or its package has sharp foreign objects, such as a staple or the object itself has a pointed object, The air sleeve piercing the film, especially for carrying the bottom of the container, causes the gas inside to escape and loses its effect, and the puncturing process may occur in the transporting movement, even if the air sleeve is punctured, it is impossible to know. Built-in items are bound to suffer damage.
In view of this, how to develop an air jacket that is not easily pierced by sharp foreign objects and has a multi-faceted anti-shock buffer structure is an urgent problem to be solved by related companies.

Moreover, the plurality of turning hinge blocks 33 are respectively disposed corresponding to the respective inflatable wall posts 30, and each of the turning hinge blocks 30 and the heat sealing line 12 of each of the inflatable wall posts 30 are spaced apart from each other to form an airflow passage that is not heat sealed (eg, As shown in the first figure, the air flow can be circulated from the first buffer body 1 to the third buffer body 3.
Between the first buffer body 1 and the second buffer body 2 and the third buffer body 3, a plurality of air flow passages 14 are respectively disposed between the air column 11 and the inflatable wall columns 20 and 30, so that the inflation airflow can flow through the first buffer. Between the body 1 and the second buffer body 2 and the third buffer body 3.
A vertical wall 24 and 34 are formed between the connecting heat sealing edges 22 and 32 of the second buffer body 2 and the third buffer body 3 to the plurality of turning hinge blocks, and the plurality of turning hinge blocks 23 and 33 are axially supported. The inside of the accommodating space 10 (as will be described later) is bent. Each of the vertical walls 24 and 34 includes a plurality of inflatable wall columns 20 and 30, wherein the plurality of turning blocks 23 and 33 of the second buffer body 2 and the third buffer body 3 are connected to the connecting nodes 13 of the first buffer body 1 They are defined as a support portion 21 and 31, respectively, in other words, the second buffer body 2 is bent to form the vertical wall 24 and the support portion 21, and the third buffer body 3 is bent to form the vertical wall 34 and the support portion. 31. Therefore, the height of each of the vertical walls 24 and 34 is smaller than the height of the support portions 21 and 31, and the angle at which the vertical walls 24 and 34 are bent depends on the size of the plurality of turning hinge blocks 23 and 33.
The suspension layer 4 is connected to the connection heat sealing edges 22 and 32 of the second buffer body 2 and the third buffer body 3, that is, the ends of the pair of vertical walls 24 and 34, and the second buffer body 2 and The third buffer body 3 collectively forms an open space 10 for the outside. The left and right sides of the suspension layer 4 respectively have an extending portion 41. One of the extending portions 41 extends integrally from the connecting heat sealing edge 22 of the second buffer body 2, and the other extending portion 41 extends integrally from the third buffer body 3. The heat seal 32 is connected. The two extending portions 41 are heat-sealed and integrated with each other, and a central portion of the two extending portions 41 substantially located in the accommodating space 10 is defined as a buffer portion 42 which is maintained between the plurality of air columns 11 of the first buffer body 1 . a spacing. The suspension layer 4 is configured to place a foreign object 5 (as shown in the fourth figure), and cooperate with the first, second and third buffer bodies 1, 2 and 3 to form a buffer sleeve having a hammock structure. The gap between the buffer portion 42 and the first buffer body 1 further provides a buffer space after the foreign object 5 is placed.
