DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a packaging bag or modified bag formed of a plastic film, such as polyethylene, and more particularly to a bag wherein the entire periphery of a pattern drawn on the bag is heat-sealed and the pattern portion is inflated with air.
BACKGROUND OF THE TECHNIQUE
Heretofore, a packaging bag and a shopping bag made of polyethylene have been formed such that two sheets of plastic films for a front side and a back side are laminated and heat-sealed along the periphery thereof, and except this, a pattern is printed on a surface of the bag, and carrying handles for carrying the bag are fixed. Therefore, such a plastic film bag is familiar to people, so that even if the bag has a unique pattern, it does not attract attention of people, thus, for the purpose of sales promotion, there has been a problem in creating novelty. Further, a bag made of cloth or leather, as disclosed in Japanese Utility Model Publication Sho 58-29951, is formed to resemble a mascot doll or stuffed doll so as to create novelty and a toy-like effect to satisfy children's desire, but much time and labor are required for selecting a material similar to a fur of an animal, sewing the bag in a shape of an animal, and, stuffing cotton into the bag, which results in a high cost.
Accordingly, in order to change bags to something new, a raw material of plastic film is changed, or an inflatable portion is provided to a packaging bag, such as an inflatable packaging bag as disclosed in Japanese Patent Application Laid-Open Publication Sho 54-136985, and a bag also serving as a portable cushion as disclosed in Japanese Utility Model Application Laid-Open Publication Sho 62-126120. However, in these bags, functions, such as use of heat insulation or a bag serving also as a cushion are mainly considered important.
DISCLOSURE OF THE INVENTION
A packaging bag or a modified bag of polyethylene, it has a structure such that a whole or a portion of a pattern drawn on the bag is composed of two sheets for a front side and a back side, by adding a material as in or different from that of the bag, and the entire periphery of the pattern is heat-sealed to surround therearound. Simultaneously with, or before or after the heat-sealing, an air inflating device, such as a mouth with a check valve, is provided to inflate the sealed portion by air.
Also, a portion to be inflated is made small and is provided adjacent to a body of the bag and the pattern is drawn to be projected from the body outwardly to obtain a good effect.
Further, the portion to be inflated may be formed of an extended portion of the film composing the body of the bag so that the portion to be inflated can be produced at the same time of forming the body of the bag.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plan view showing one embodiment of the present invention;
FIG. 2 is a plan view of heat sealing lines thereof;
FIGS. 3, 4, and 9 are plan views showing other embodiments; and
FIGS. 5-8 are plan views showing neat sealing lines of modifications of the embodiment shown in FIG. 4.
BEST MODES FOR EMBODYING THE PRESENT INVENTION
In explaining the invention with reference to the drawings, FIG. 1 is a plan view showing an embodiment, and FIG. 2 is a plan view of heat sealing lines thereof. A modified bag 1 shown in the drawing is formed such that a contour of a body 2 of the bag for containing articles therein and a pattern 3 of Santa Clause adjacent to the body 2, which are drawn on two laminated sheets of polyethylene films, are heat sealed except for an opening 4 of the bag and a portion to be provided with a mouth 5 with a check valve, and the outside portions thereof are cut off.
Then, the bag is completed by providing a string-fixing portion 7 at the opening 4 of the bag, a string 8, and the mouth 5 with the check valve at the Santa Clause, which is a thin-flat type tube and is usually used in a polyethylene balloon.
If air is blown through the mouth 5 with the check valve by means of a straw, since the modified bag 1 comprises two s
