For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

A suspendable vacuum storage bag according to the present invention comprises a storage bag body 1 having a single opening and a sealable opening 11 at the single opening, and a suspending device 4 provided at an end opposite to the sealable opening 11 or adjacent thereto. After articles 5 are flatly placed into the storage bag body 1 via the sealable opening 11, the sealable opening 11 is sealed by using rod fitting means 3 or hot press lines 6 or male and female engaging means 7, and suspending hook portions of the articles 5 may be suspended on a suspending plate 43 adapted to hold several hook portions to achieve optimum use of available storage space. The suspending device 4 may be suspended by means of a suspending element 41 or a hanging hook 44 depending on the environment in which it is used.

Referring to FIG. 1, the sealable opening 11 of the storage bag body 11 is sealed by using rod fitting means 3. The discharge of air is by utilizing a suction device 2. In the present invention, the suspending device 4 utilizes a suspending element 41 having a thin plate 412 with thickness-enlarged portions on both sides thereof to couple firmly to the sealed opening of the storage bag body 1. The thickness-enlarged portions of the suspending element 41 are each provided with a through hole 411 (as shown in FIG. 3). The through hole 411 on the outer rim of the storage bag body 1 is provided to fasten to a hanging hook 81 of a clothes hanging device 8. The through hole 411 on theinner rim of the storage bag body 1 is coupled to a hook element 42 having a substantially C-shaped opening. The hook element 42 is further coupled to a suspending plate 43 having a plurality of in-line spaced through holes 431. The rod fitting means 3 includes a hollow rod 31 and a fitting rod 32 having a C-shaped cross section. To seal the sealable opening 11 of the storage bag body 1, a suitable length of the sealable opening 11 is wrapped on the outer circumference of the hollow rod 31 for one round, and the fitting rod 32 is pressed over the hollow rod 31 fittingly to hold that length of the sealable opening 11 firmly on the circumference of the hollow rod 31. Referring to FIG. 2, the suction device 2 includes a seat 21, a press plate 22, a rotary cover 23 and a top cover 24. The seat 21 is coupled to the storage bag body 1 by hot fusion and has a projecting connecting portion 211 at its center. The connecting portion 211 has an inner wall provided with threads forming an internally threaded portion 212. The outer peripheral portion of the seat 21 is provided with radially spaced air vents 215, see FIG. 2A. Each air vent 215 has divider plates 214 of a certain height at lower outer edges thereof to prevent blockage by the articles 5 during air discharge and facilitate speedy discharge of air. The center of the connecting portion 211 is a through air hole 213 for entry and exit of air, the top outer edge thereof being provided with divider plates 214 as well. The press plate 22 resembles a disk having a central opening. The periphery of the central opening is provided a plurality of spaced bosses 221 for retaining and positioning the seat 21 after the central opening is fitted over the connecting portion 211. The rotary cover 23 has an annular raised opening 231 at the center of its upper side. The periphery of the inner wall of the raised opening 231 is provided with a plurality of air vents 232 while the center thereof forms a recess 233 for receiving an air stop 234 made of soft silicon rubber. A lower portion of the raised opening 231 extends downwardly to form an externally threaded portion 235 (see FIG. 5) that matches the threaded portion 212 of the connecting portion 211 of the seat 21. After articles 5 have been placed flatly inside the storage bag body 1 and the sealable opening 11 has been closed by rod fitting means 3, air inside the bag body 1 is drawn out by using a vacuum cleaner, and the air will escape from the air hole 213 and air vents 215 of the seat 21 in the direction as shown in FIG. 5A. When all the air inside the bag body 1 has been removed, the rotary cover 23 is tightened (as shown in FIG. 5B) so that the air stop 234 tightly stops the air hole 213 of the seat 21. The top cover 24 is then fitted over the raised opening 231 to prevent reverse flow of air into the bag body 1, thus achieving a vacuum state in the bag body 1.

Referring to FIG. 4, the vacuum storage bag may be suspended on the hanging hook 8 of the clothes hanging device 8 by means of the through hole 411 on the suspending element 41 of the suspending device 4.

Referring to FIG. 6, the outer edge of the suspending element 41 of the suspending device 4 is further provided with a hook element 42 and a hanging hook 44. The hanging hook 44 has a relatively large curved opening and has one end thereof suspended on a clothes hanging rod 9 with the other end provided with a hook hole 441 for receiving one end of the hook element 42.

Referring to FIG. 7, the sealable opening 11 of the bag body 1 may also be sealed by hot press lines 6 using a hot press sealing machine. For the same reasons, the sealable opening 11 may also be sealed by male and female engaging means 7.

Referring to FIG. 9, one side of the bag body 1 is configured to have an S- shaped portion having two air exits 111 at both ends and an air channel 110. The air exits 111 extend from the bag body 1 for a certain length. After the air has been totally extracted, the S-shaped portion is closed by using a rod fitting means 100 including a rod 111 and a fitting rod 102 of a C-shaped cross section. The sealable opening 11 of the bag body may also be closed by rod fitting means 3, male and female engaging means 7 (as shown in FIG. 10) or hot press lines 6 (as shown in FIG. 11). The suspending device 4 may then be provided on one of the remaining two sides at the center and may include a suspending element 41 or hook element 41 and hanging hook 44 depending on the environment in which the storage bag is used.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
