Description

TR

This invention relates to a packaging bag, more particularly to a packaging bag having an anti-slip plastic layer.

Generally, goods for delivery are first packed in a plurality of conventional packaging bags, after which the packaging bags are stacked one on top of the other in a warehouse or in a delivery truck. However, the packaging bags fall down easily fromtheir stacked state either because they are not arranged neatly and orderly, or because of the vibrations produced by the moving vehicle. Hence, use of the conventional packaging bags is not only inconvenient, but also can pose a danger.

According to this invention, a packaging bag comprises a plain woven plastic bag body having two opposite major walls facing each other to define an accommodation space, and at least one anti-slip plastic layer formed by thermo-coating on an outer surface of at least one of the majorwalls so as toprovidea frictional force for preventing slippage of the bag body.

Other features and advantages of the present invention will become apparent in the following detailed description of thepreferredembodimentsof the invention, withreference to the accompanying drawings, in which:

Fig. 1 is a fragmentary perspective view of a packaging bag according to the first preferred embodiment of this invention;

Fig. 2 is a sectional view of the first preferred embodiment;

Fig. 3 illustrates a plurality of the packaging bags of the present invention in a state stacked one on top of the other;

Fig. 4 is a sectional view of a packaging bag according to the second preferred embodiment of this invention;

Fig. 5 is a sectional view of a packaging bag according to the third preferred embodiment of this invention; and

Fig. 6 is a fragmentary perspective view of a packaging bag according to the fourth preferred embodiment of this invention.

Before the present invention is described in greater detail, it should be noted that the same reference numerals have been used to denote like elements throughout the specification.

Referring to Figs. 1 and 2, a packaging bag 1 according to the first preferred embodiment of the present invention is shown to comprise a bag body 11 and an anti-slip plastic layer 12.

The bag body 11 has two opposite major walls 13, 13’ facing each other and defining an accommodation space 131, and has an opened end 14, and a closed end 15 opposite to the opened end 14. In this embodiment, the bag body 11 is a plain woven bag made from polypropylene. Alternatively, the plain woven bag may be made from polyethylene. The material of theplainwovenbagisnot limitedtotheaforesaid

. 3 oo disclosures.

In this embodiment, the anti-slip plastic layer 12 is formed by thermo-coating on an outer surface of the major wall 13 of the bag body 11, extends longitudinally between the opened and closed ends 14, 15, and is made from polypropylene. Alternatively, the anti-slip plastic layer + 12 may be made from polyethylene or polyvinyl chloride, and : is not limited to the aforesaid disclosures.

Referring to Fig. 3, during a plurality of the packaging bags 1 are stacked for transport, through the presence of the anti-slip plastic layers 12 on the outer surfaces of the major walls 13 of the bag bodies 11 of the packaging bags 1, frictional contact among the bag bodies 11 can be enhanced, so that falling over or slippage of the stacked packaging bags 1 due to a rocking movement or vibrations can be effectively minimized or prevented. Hence, the inconvenience of having to re-stack the packaging bags 1 or the danger posed by the packaging bags 1 falling over can be largely reduced. Further, the effectiveness of the + 20 anti-slip plastic layer 12 cannot be easily lowered due to contact with dirt.

Referring to Fig. 4, a packaging bag 1’ according to the second preferred embodiment of the present invention is shown to be similar to the first preferred embodiment.

However, in this embodiment, the packaging bag 1’ further has another anti-slip plastic layer 12’ formed by thermo-coating on the outer surface of the other major wall

13" of the bag body 11. During a stacking operation of the packaging bags 1’, there is no need to pay particular attention to the stacking direction of the bag bodies 11 of the packaging bags 1’ since the major walls 13, 13’ of the bag bodies 11 are provided respectively with the anti-slip plastic layers 12, 12’. Hence, the advantages of the packaging bags 1’ discussed above can be effectively further enhanced.

Referring to Fig. 5, a packaging bag 1” according to the third preferred embodiment of the present invention is shown to be similar to the first preferred embodiment.

However, in this embodiment, the anti-slip plastic layer 12” covers completely the outer surfaces of the major walls 13, 13’ of the bag body 11. Advantages of the first preferred embodiment can be similarly achieved using the third preferred embodiment. It should be noted that the anti-slip plastic layer 12” may be configured as a netted structure that surrounds the outer surfaces of the major walls 13, 13’ of the bag body 11.

Referring to Fig. 6, a packaging bag (la) according to the fourth preferred embodiment of the present invention is shown to be similar to the first preferred embodiment. :

However, in this embodiment, the anti-slip plastic layer (12a) has an outer surface provided with a plurality of anti-slip protrusions 121 projecting outwardly therefrom.

Advantagesofthefirstpreferredembodiment canbe similarly achieved using the fourth preferred embodiment.
