A sealing cover and an adhering piece seal the hole of the vent. Thereby, outer air can not flow into the bag.

Description

FIELD OF THE INVENTION

The present invention relates to a receiving bag, and particularly to a bag having a sealing clip, a preferred air exhausting function, and a function for preventing air to flow back to the bag.

BACKGROUND OF THE INVENTION

The prior art receiving bags and sealing bags have sealing tracks and sealing strips on the bag openings. The engagement of the sealing track and sealing strip is executed by hands. However, this work is time-consumed and it is possible that the opening is not completely sealed.

Referring to FIG. 21, a sealing clip is developed. The sealing clip may be used to seal an opening by hands. The sealing

clip

1 is formed by a long rod 10 and a short rod 11. The rods 10 and 11have cambered inner walls. Two sides of the short rods 11 are installed with protrusions 111. The opening ends of the

rods

10 and 11 are installed with

hooks

101 and 112. Although the sealing clip has the effect of improving the defect of operating by hands, this prior art has the following defects:

1. Since the

hooks

101 and 112 are over-protruded, as the sealing clip is placed in the bag opening, the two rods of the seal opening have a trend to move outwards, thereby, the bag opening being moved into the sealing clip easily.

2. It is very possible that due to an improper force, the sealing track and sealing strip are shifted away from a normal position so that the two can not be well arranged.

3. As the sealing clip moves to a distal end of the bag body, it is very easy to separate from the bag opening and thus can not stop at a distal end of the bag opening.

Besides, another end of the receiving bag has a seal opening. The seal opening is an S shape air venting loop, such as that disclosed in U.S. Pat. No. 6,116,781. Referring to FIG. 1 of the prior art, when air in the bag will be vented, air flows from the

outlet

31 through the flow path 16 to the outlet 32 for venting. The advantage of this bag is that the volume of the bag can be reduced. However, it has still the following disadvantages. The two

outlets

31 and 32 of the seal opening are not sealed completely. After being used for a long time, air is possible to flow back to the bag.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a receiving bag with a seal opening and a sealing clip. One end of the receiving bag is installed with a sealing opening. An opening at another end of the receiving bag has a sealing track and a sealing strip matching to the sealing track. A sealing clip serves to tightly seal the sealing track and the sealing strip. The sealing clip is made of an upper clamping plate, a lower clamping plate, a bending portion, and a stopper. At inner walls of opening ends of the upper clamping plate and the lower clamping plate are formed with trenches, respectively. The trenches serve to tightly seal the sealing track and the sealing strip of the seal opening. The bending portion is formed between the upper clamping plate and the lower clamping plate. A center of the bending portion is installed with a protruded stopper. The length of the stopper is smaller than those of the upper clamping plate and the lower clamping plate. By the stopper, as the sealing clip is pushed to one side of the seal opening, it will be resisted by the stopper so as not to separate from the seal opening. There are buckles and buckling holes on the upper clamping plate and lower clamping plate, respectively, thereby, the engaged upper clamping plate and lower clamping plate can not be separated.

Furthermore, the present invention provides a receiving bag with a seal opening and a sealing clip. The sealing opening of the receiving bag has a seal wire, a flow path and an outlet. The sealing wire is installed with at least one vent valve. The vent valve is installed at one end of the flow path and an outlet is installed at another end of the flow path. By the vent valve, the air within the bag can be drained out through a flow path. The vent may be a plastic vent. A seal cover or a sticky piece can be used to seal the vent opening so that outer air can not flow into the bag.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a schematic view of the sealing clip of the present invention is illustrated. The sealing [0039] clip 10 illustrated in the figure is installed at a bag opening 101 of a receiving bag 100. The sealing clip 10 is movable on the bag body and is capable of clamping the bag opening 101 so that the sealing tracks 102 are sealed by the sealing strip 103. The sealing track 102 is a long protruded track having an embedded track. The sealing strip 103 is a long protruded strip with a tenon (not shown).
FIG. 2 is a perspective view of the sealing clip according to the present invention. The sealing [0040] clip 10 in the figure has an upper clamping plate 1, a lower clamping plate 2, a bending portion 3, and a stopper 4 which are formed integrally. The length of the upper clamping plate 1 is identical to that of the lower clamping plate 2. The upper clamping plate 1 and lower clamping plate 2 are formed with respective trenches 11 and 21. The upper clamping plate I has a buckle 12 at a selected position. The lower clamping plate 2 is installed with a buckling hole 22 configured with respect to the buckle 12. Then, the bending portion 3 is installed between the upper clamping plate 1 and lower clamping plate 2 and has a V shape notch 31 between the bending portion 3 and the upper clamping plate 1, thereby, the upper clamping plate 1 being movable and bendable. Another V shape notch 32 is formed between the bending portion 3 and the lower clamping plate 2. A protruded stopper 4 extends from the center of the bending portion 3. The length of the stopper 4 is smaller than those of the upper clamping plate 1 and the lower clamping plate 2.
FIG. 3 is a cross sectional view of the sealing clip. The upper clamping plate I and [0041] lower clamping plate 2 are bent to be adhered to one another. The buckle 12 is engaged to the buckling hole 22 so that the upper clamping plate 1 and lower clamping plate 2 are adhered to one another. Further, the trench 11 is positioned to be correspondent to the trench 21.
FIG. 4A is a schematic view showing that the receiving [0042] bag 100 is not sealed. In the figure, an upper and a lower end of the bag opening 101 are installed with a sealing track 102 and a sealing strip 103, respectively. The sealing track 102 and the sealing strip 103 are engageable. FIG. 4A shows a schematic view showing that the sealing clip of the present invention clamps the opening of the receiving bag. When the sealing clip 10 clamps the bag opening 101, through the user's fingers to apply a force thereto, the sealing strip 103 will be enforced to enter into the sealing track 102 so as to be engaged tightly with the sealing track 102. FIG. 4C is a schematic view showing that the bag opening 101 of the receiving bag is sealed. When the sealing clip 10 is released, the bag opening 101 will be sealed due to the engagement of the sealing track 102 and the sealing strip 103.
FIG. 5A is a perspective view of another sealing [0043] clip 10. The different to aforesaid structure is that the buckle 12 of the upper clamping plate 1 is replaced by a clamping track 13. The buckling hole 22 at the lower clamping plate 2 is replaced by a clamping strip 23. When the upper clamping plate 1 and lower clamping plate 2 are combined, the sealing strip will be enforced to enter into the clamping track 13 to be sealed therein. As a result, a sealing effect is achieved, as illustrated in FIG. 5B.
Referring to FIGS. 6A and 6B, a perspective view and schematic view of another sealing [0044] clip 10 is illustrated. The upper clamping plate 1 and lower clamping plate 2 of the sealing clip 10 are installed with respective blocks 14, 24. The upper clamping plate 1 is formed with a through hole 15 and a resisting hole 16 at selective positions. The lower clamping plate 2 is installed with a through hole 25 and a resisting hole 26 at position corresponding to the through hole 15 and resisting hole 16. After the C buckles 5 pass through the through holes 15 and 25, two ends of the C buckles 5 resist against the resisting holes 16 and 26. By the resisting and buckling effects of the C buckles 5, the upper clamping plate I and lower clamping plate 2 have a clamping effect so as to present a clamping effect as the function of the buckle 12 and the buckling hole 22. Next, when the user presses the distal end of the sealing clip 10, as shown in FIG. 6C, the blocks 14, 24 serve as center fulcrums. The front ends of the upper clamping plate I and lower clamping plate 2 expands outwards and thus is opened so as to separate the bag opening 101. On the contrary, when it is desired to place the bag opening 101 into the sealing clip 10, a respective operation can be performed.
An operational schematic view of the present invention is illustrated in FIG. 7A. When the sealing [0045] clip 10 is pushed to move to a lateral end of the bag opening 101, the stopper 33 is resisted by the lower end of the opening (referring to FIG. 713) so as to be resisted in the bag opening 101 to avoid that as the sealing clip 10 moves to the lateral side, it is separated from the bag opening 101.
FIG. 8A is an operation schematic view of the present invention. A distal end of the [0046] bag opening 101 is installed with a protruded strip 104. When the sealing clip 10 moves to the distal end of the bag opening 101, other than the stopper 33 is resisted by the lower end of the bag opening 101, the upper clamping plate 1 and lower clamping plate 2 are resisted by the protruded strip 104, thereby, the sealing clip 10 being prevented from separation.
A perspective view of the receiving bag of the present invention is illustrated in FIG. 9. One end of the receiving [0047] bag 100 is the bag opening 101. Another end is a sealing opening 105. The sealing opening 105 has a seal wire 106, a flow path 107 and an outlet 108. The sealing wire 106 is installed with at least one vent valve 6. Besides, the vent valve 6 must be installed at one end of the flow path 107, while the outlet 108 is installed at another end of the flow path 107, as shown in FIG. 10. When an object 200 is received from the bag opening 101 of the receiving bag 100, to vent the air in the bag so as to reduce the volume thereof, the bag opening 101 can be sealed at first, then the bag is wound so as to compress the internal air, thereby, the air being vented out from the drain value 107 to the flow path 107, and then is vented out from the outlet 108. Once the air is drained out, the outer air is hard to flow back to the receiving bag 100 from the vent valve 106. With reference to FIG. 10, when air in the bag is vented out, the receiving bag 100 can expand, then the volume in the bag must be smaller than that before the air is vented, thereby, the objects of easy operation and venting and reducing the volume being achieved.
Referring to FIGS. 12 and 13, the perspective view and exploded view of the [0048] vent valve 6 are illustrated. The vent valve 6 is formed by an upper plastic sheet 61 and a lower plastic sheet 62 which are symmetrically and one or two small heat tolerant sheets 63. One end of the vent valve 6 with the heat tolerant sheet 63 is formed as an inlet end 64, and another end is installed as an outlet end 65. The vent valve 6 moves into the receiving bag 100. By thermal pressing process, sealing wires 106 are shaped on the bag. The sealing wires also melt and then is fixed to the vent valve 6. Since the inlet end of the vent valve 6 has the heat-tolerant sheet 63, it dose not melt, and thus a small opening is formed. In normal, the opening is closed. It is opened only as it is affected by air pressure. Another structure of the vent valve is illustrated in FIG. 14. The difference from aforesaid embodiment is that the sealing edge of the lateral side 66 near the outlet end 65 is widened by thermal pressure so that the width of the outlet become small. Therefore, it is difficult for outer air to flow back from the outlet 65.
FIG. 15 shows a cross sectional view, wherein the [0049] vent valve 6 vents air. When a pressure is applied to the receiving bag 100 and then air is vented, the inlet end 64 of the vent valve 6 will open so that air is vented out. On the contrary, after the air in the bag has been exhausted, as shown in FIG. 16, since the air pressure in the bag has been released, the vent valve 6 will restore to the original flat shape. Therefore, the outer air is hard to flow back to the bag from the outlet end 65 and inlet end 64. Therefore, the vent valve 6 has the function of preventing air to flow back.
Besides, referring to FIG. 17, to prevent the air from flowing back from the [0050] outlet 108, in this embodiment, no outlet 108 is formed. One end of the flow path 107 of the receiving bag 100 is further formed with a plastic vent 109, and another end is installed with a vent valve 6 or a vent 109 (referring to FIG. 18). The vent 109 has a bottom plate which is combined with the receiving bag 100 to be as an integral body (referring to FIG. 19). When air is exhausted from the bag, a soft plastic cover 7 seals the vent 109 so that outer air can not flow into the bag. Besides, as shown in FIG. 20, a strong sticky sheet 8 is adhered to an opening of the plastic vent 109. After the vent 109 is sealed, no outer air can flow into the bag so that the bag is sealed completely.
The present invention are thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
