SEAL-FREE POUCH
A seal-free pouch includes a bag body, a tear and a feeding unit. The bag body is provided for forming a first accommodating space. The tear is interconnected with the first accommodating space. The feeding unit includes a protrusion and is installed on a side of the tear for partitioning the tear to form a second accommodating space and a third accommodating space, and the second accommodating space is interconnected with the tear, but the third accommodating space is not interconnected with the tear. If the protrusion of the feeding unit is folded into halves along the third accommodating space, the first accommodating space will be limited and interconnected with the exterior of the seal-free pouch through the second accommodating space.
The present invention relates to a seal-free pouch, in particular to a pouch using a feeding unit installed on a bag body for sealing the pouch without requiring any additional equipment or device.
BACKGROUND OF THE INVENTIONTraditionally, sealing a bag for storage can be divided into the following ways: zippering, buckling, sewing, thermoplastic sealing and screw capping, etc. The aforementioned prior arts are mainly divided into two types: using an external equipment to seal a bag by heat or using a machine to sew a seal opening of a bag, and adding a sealing device such as a zipper, a button, or a screw cap on a seal opening of the bag.
However, the aforementioned ways of sealing a bag still have drawbacks, such as requiring an additional equipment for sealing the bag, thus incurring a higher cost indirectly, and manufacturing a sealing device for the bag, thus increasing the complexity of manufacturing method and procedure.
SUMMARY OF THE INVENTIONIn view of the aforementioned shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a seal-free pouch and a method of sealing the seal-free pouch in accordance with the present invention to achieve the effects of saving cost and using the seal-free pouch repeatedly for the environmental protection purpose.
Therefore, it is a primary objective of the present invention to provide a seal-free pouch that uses a feeding unit integrated with a bag body to seal the pouch without requiring any additional equipment or device, but simply storing the feeding unit into the bag body in a direction to limit a substance (or injectant) injected inside the bag body.
Another objective of the present invention is to provide a seal-free pouch having a plurality of frictional areas formed on a side of the bag body for changing the of the bag body coefficient of friction, in addition to limiting the injectant in the bag body by the feeding unit, such that when the plurality of bag bodies are stacked, the seal-free pouches can be stacked more securely.
In a preferred embodiment, the present invention provides a seal-free pouch, comprising a bag body, a tear and a feeding unit. The bag body is used for forming a first accommodating space. The tear is interconnected with the first accommodating space. The feeding unit includes a protrusion disposed on a side of the tear for partitioning the tear to form a second accommodating space and a third accommodating space, wherein the second accommodating space is interconnected with the tear, but the third accommodating space is not interconnected with the tear. When the protrusion of the feeding unit is folded into halves along the third accommodating space, the first accommodating space is limited and interconnected with the exterior of the seal-free pouch through the second accommodating space.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

It is noteworthy to point out that the protruding height HA of the protrusion 2062 falls in an acceptable range as long as the protrusion 2062 can be folded and inserted into the third accommodating space 2068 easily, and HA is set according to actual requirements. In this preferred embodiment, the height HA of the protrusion 2062 is equal to the height HB of the second accommodating space 2066 and the third accommodating space 2068, or the width of the protrusion 2062 of the feeding unit 206 is slightly greater than the width of the tear 204 as shown in
In addition, the feeding unit 206 further includes a pre-formed folding line 2064 pressed among the protrusion 2062, the second accommodating space 2066 and the third accommodating space 2068 for facilitating a seal-free packaging process. The bag body 202 further includes a plurality of folding lines 2024 provided for pressing a three-dimensional seal-free pouch 200 into a flat bag body 202, such that the bag body 202 can be transported, carried and stored easily before the injectant is filled.
