INFLATABLE PROTECTIVE BAG
An inflatable protective bag includes a housing sack, a gasbag, an inflation means, a check valve and a deflation valve. The gasbag is attached to an inner surface of the housing sack. The inflation means communicates with the gasbag through the check valve. The deflation valve is located on the gasbag. When the housing sack contains goods, air can be injected into the gasbag by the inflation means through the check valve to inflate the gasbag to provide resilient protection for the goods from being damaged. The air can be released from the gasbag by pushing the deflation valve to facilitate removing of the goods. Thus the inflatable protective bag can provide protection as desired.
The present invention relates to a bag for holding goods and particularly to a bag to provide protection of goods held inside.
BACKGROUND OF THE INVENTIONIn order to protect goods from being damaged during transportation, a conventional approach is using a bag lined with an elastic filler inside to hold and protect the goods to cushion impact. To make protection effective, the elastic filler has to be substantial in quantity and evenly distributed. This results in a greater size and makes storage of the bag difficult. Moreover, loading the goods into the bag also is cumbersome.
To remedy the aforesaid drawback, a handbag 1 equipped with an airtight bag 2 inside is being developed as shown in
In the aforesaid conventional technique, air (not shown in the drawings) is injected into the airtight bag 2 through the nozzle 3. The nozzle 3 has a round orifice 5 insertable by a plug 4. During inflation, the plug 4 is removed and the round orifice 5 is blocked by a user's mouth or an air injection means (not shown in the drawings) to inject air. After the bag is inflated, user's mouth or the air injection means is quickly removed and the plug 4 is inserted again. To inexperienced users, the time elapsed between removing the mouth or the air injection means and inserting the plug 4 could cause leakage of considerable amount of air from the airtight bag 2. Thus air pressure in the airtight bag 2 is lower and results in undesirable protective effect. Moreover, the conventional airtight bag 2 is located outside the handbag 1. It is not aesthetic appealing and easily broken by scraping with outside objects and makes protection of goods ineffectual.
SUMMARY OF THE INVENTIONTherefore, the primary object of the present invention is to provide an inflatable protective bag that can be inflated and deflated easily to improve usability.
To achieve the foregoing object, the inflatable protective bag according to the invention includes a housing sack, a gasbag, an inflation means, a check valve and a deflation valve. The housing sack has a housing space with a surface holding the gasbag. The inflation means communicates with the gasbag and generates air to be injected into the gasbag. The check valve is interposed between the inflation means and the gasbag to allow the air entering the gasbag one way. The deflation valve is located on the gasbag to release the air from the gasbag.
The structure thus formed allows the inflation means injecting air into the gasbag. The deflation valve can release the air from the gasbag. Operation is simple and can be easily used by ordinary users. Through the inflation means and deflation valve, the air saturation extent of the gasbag can be adjusted easily to provide optimal protection effect according to varying requirements of different goods.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

As a conclusion, the present invention can inject air into or release air from the gasbag 20 through a simple operation. It can be easily used by ordinary users. Through the inflation means 30A, 30B or 30C and the deflation valve 50, the saturation extent of the gasbag 20 can be adjusted to provide optimal protection effect according to different goods.
Claims
1. An inflatable protective bag, comprising:
- a housing sack having a housing space;
- a gasbag located on the surface of the housing space;
- an inflation means communicating with the gasbag and generating air injected into the gasbag,
- a check valve interposed between the inflation means and the gasbag to allow the air entering the gasbag one way; and
- a deflation valve located on the gasbag to release the air from the gasbag.
2. The inflatable protective bag of claim 1, wherein the inflation means is located on the surface of the housing sack communicating with the gasbag through an air duct.
3. The inflatable protective bag of claim 2, wherein the check valve is located between the inflation means and the air duct.
4. The inflatable protective bag of claim 3, wherein the deflation valve has an air release button, a channel and an elastic element; the channel communicating with the air duct and extending to the surface of the housing sack, the air release button being held in the channel and jutting outside the surface of the housing sack upon elastically pushed by the elastic element to close the channel, the channel being opened when the elastic element is compressed by the air release button.
5. The inflatable protective bag of claim 3, wherein the check valve has two membranes bonding together to form a passage therebetween to communicate with the inflation means and the air duct, the two membranes having at least one contact surface coated with a release layer at one end of the passage close to the inflation means.
6. The inflatable protective bag of claim 1, wherein the check valve has two membranes bonding together to form a passage therebetween to communicate with the inflation means and the air duct, the two membranes having at least one contact surface coated with a release layer at one end of the passage close to the inflation means.
7. The inflatable protective bag of claim 1, wherein the inflation means is an elastic gasbag having an opening.
8. The inflatable protective bag of claim 1, wherein the inflation means is an elastic gasbag having a one-way valve.
