DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an impact resistant wrapping system. More particularly, this invention relates to an improvement in versatility and repetitious usability of such an impact resistant wrapping system capable of forming an impact resistant chamber inflatable with gas around an article to be protected.
BACKGROUND ART
There have been so far known wrapping implements having an impact resistant chamber inflatable with gas as described in, for example, Japanese Utility Model Application Public Disclosure No. HEI 4-3974(A).
This conventional impact resistant wrapping system comprises gas-barrier flexible wall members between which partitioned wall chambers are formed, and a check valve for introducing air into the wall chambers. The wrapping system is affixed to the inner surface of a packing case in use. Before or after putting the article to be protected into the packing case, the air is injected into the wall chambers through the check valve so as to form a shock-absorbing space with which a gap between the packing case and the article is filled in.
The aforementioned prior art impact resistant wrapping system has suffered disadvantages such that it invariably calls for a packing case because it must be integrally united to the packing case in use, and cannot protect an article which is notably different in shape from the packing case and thus is not versatile. Furthermore, since the conventional wrapping system is bonded to the packing case and is not furnished with an effective means for releasing the air from the wall chambers, it is difficult to reuse.
This invention was made in view of the foregoing problems and has the object of providing an impact resistant wrapping system having high versatility and repetitious usability and capable of repeatedly wrapping articles of various shapes and sizes.
SUMMARY OF THE INVENTION
To solve the problems as described above, according to the present invention, there is provided an impact resistant wrapping system possessing the following:
That is, the impact resistant wrapping system according to this invention comprises a sheetlike wrapping body formed of gas-barrier flexible wall members which are closely partitioned or partially joined to one another. The sheetlike wrapping body is provided with an intake tap capable of injecting gas into the wall chambers and exhaust taps for releasing the gas from the wall chambers. The intake and exhaust taps are integrated so as to be used in common or formed separately. The exhaust taps are arranged between the closely partitioned wall chambers in one line or two or more lines intersecting to the wall chambers so that the adjacent wall chambers communicate with one another through the exhaust taps, thereby allowing the exhaust tap of the outermost wall chamber to communicate to the outside of the sheetlike wrapping body. Also, the exhaust tap in the aforesaid wrapping system may be formed of a flat cylinder made of thin synthetic resin film.
Furthermore, an exhaust pipe, which is provided in its peripheral surface with a number of pores and can be inserted successively into the exhaust taps, may be used.
Moreover, the impact resistant wrapping system according to this invention comprises a sheetlike wrapping body formed of gas-barrier flexible wall members between which partitioned wall chambers are formed so as to partially communicate with a plurality of passages. The sheetlike wrapping body is provided with an intake tap capable of injecting gas into the wall chambers and exhaust taps for releasing the gas out of the wall chambers. The intake and exhaust taps are integrated so as to be used in common or formed separately. The wrapping body is provided with intermediary taps disposed between the closely partitioned wall chambers, thereby allowing the exhaust tap of the outermost wall chamber to communicate to the outside of the sheetlike wrapping body through the plurality of passages.
According to the aforementioned structure, the wall chamber in the sheetlike wrapping body is inflated with gas
