Description

Fluid Filled Bag with Sealed Section around Center Portion Thereof}

The present invention relates to an envelope for storing fluid such as detergents in a sealed form. More specifically, in an upright type fluid receiving bag in which a slope is sealed using a commercially available sealant, the fluid receiving bag may have a sealing area wider at an intermediate portion so that the top of the bag may be formed in a wrinkle-free form. It is about.

Conventionally, a fluid container is used as a plastic bottle, but nowadays, an envelope-type container such as FIG. Such a fluid accommodating bag is composed of a front part 1, a rear part 2 and a bottom part 6 as shown in FIG. The front part 1 and the rear part 2 are each in the form of a rectangle, and each side is sealed to seal each other. In addition, the front portion (1) and the rear portion (2) at the bottom of the bag is sealed with the bottom portion (6), respectively, to form a wide bottom to secure a space for accommodating the fluid, and to give stability so that the bag does not fall even if the fluid is contained. do.

As a material of the front part 1, the back part 2, and the bottom part 6, the adhesive and the secondary paper, or the substance which synthesize | combined the adhesive, the secondary paper, and the resin through a certain process are used. Looking at the process of processing the fluid receiving bag with reference to Figure 3 while winding the two rolls (not shown) while cutting while supplying the fabric made of the material. The fabric of one roll is used for the front part 1 of the fluid receiving bag and the fabric of another roll is used for the back part 2. Rotating the two rolls in the upper and lower position close to supply the far end of the front portion (1) and the rear portion (2). A material for the bottom portion is inserted in the middle of the supply stage (not shown), and then a first sealing process for sealing each side surface of the front portion 1, the rear portion 2 and the bottom portion 6 using a heater; It is going through the second sealing process to cut into a single fluid receiving bag.

However, although the width of all the seals 4 is constant and the width of the bags is almost the same at the upper and lower sides of the fluid accommodating bag, the lower part of the fluid accommodating bag is attached to the bottom part 6 to secure space for accommodating the fluid. In the upper part, only the front part 1 and the rear part 2 are sealed. Therefore, in the case of receiving the fluid, the lower part of the fluid receiving bag that contains a lot of fluid is pressurized by the receiving fluid, and the upper part is hardly influenced by the receiving fluid, so the tension between the sides of the bag is not uniform in the upper and lower parts. If received, wrinkles or creases will occur on the top. This is not only aesthetically unfavorable, but when displayed in a general sales place, there is a problem that the brand name or trade name displayed on the front surface is covered by the crumpled portion of the upper part, which is inconspicuous to the consumer.

Therefore, the present invention by making the sealing area in the middle portion of the fluid receiving bag in order to eliminate the wrinkles on the top of the fluid receiving bag wider than other areas by making the force pulled to the side in the middle of the fluid receiving bag stronger, The purpose is to remove the upper wrinkles so that the brand name, etc. printed on the front surface is refracted, and looks good.

In order to achieve the above object, the present invention provides a fluid receiving bag having a generally rectangular front and rear portions and a lower bottom portion attached to a lower portion thereof, which are sealed at each side. Provided is a fluid accommodating bag which allows the sealing area of the seal to be wider than the sealing area of other portions.

Hereinafter, the configuration of the present invention with reference to FIGS. 1 and 2 are as follows.

As shown in FIGS. 1 and 2, the present invention is largely composed of a front part 1, a rear part 2, and a bottom part 6.

The front part 1 and the rear part 2 are made of a material of a rectangular shape, and the material is a material obtained by synthesizing an adhesive and a secondary paper or an adhesive, a secondary paper and a resin through a predetermined process as in the prior art. The side of the front part 1 and the side of the back part 2 are sealed using a heater and form a central sealing part 3 in the middle part of the side which seals to an area larger than the width of the other sealing part 4. According to the present invention, the heater can be manufactured in a larger area than the other parts in the middle part where the center sealing part 3 exists in the conventional sealing process, and thus the center sealing part 3 can be formed even in the conventional process. There is another advantage of.

As such, the middle portion of the envelope, that is, the portion with the central sealing portion 3, is filled with the contents such as a fluid to provide a stronger tension between the sides of the envelope than other portions when the envelope is inflated, and also when the envelope is inflated The portion 3 serves as a support for the top of the fluid receiving envelope while providing a tight tension on the top of the envelope. Therefore, when the fluid receiving bag is erected, the tensile force reaches the top of the bag so that the top is always taut to maintain the shape of the bag.

The central sealing portion 3 may be preferably a semi-circular shape, but the shape thereof is not specific and may have a larger area than other sealing portions. That is, it is sufficient if the sealing area can be secured to some extent by adjusting the depth and width of the center sealing part 3 suitably. And the position of the center seal 3 is preferably movable according to the amount of fluid.

The bottom part 6 is made of the same material as the front part 1 and the rear part 2, and is sealed with the lower side of the front part 1 and the rear part 2 on both sides of the bottom part 6. Create a space to accommodate it. At this time, the front side and the rear side side is preferably sealed in a triangular shape (5) to be able to receive the fluid stably.

The central sealing portion 3 of the fluid accommodating bag according to the present invention has a larger sealing area than the other sealing portions 4, and a bottom portion 6 is formed at the lower portion thereof to secure a space for accommodating the fluid. . However, since the width of the front part and the rear part is wider than the width of the bag toward the top, the tensile force acting between the sides of the bag becomes smaller than that of other parts. To prevent this, if the center sealing part 3 is formed in the center part, The tension between the sides will be compensated. In addition, when the envelope is inflated as the fluid is received, the central sealing portion 3 serves as a support for the top of the envelope, while providing a taut tension on the top of the envelope. Thus, when the fluid receiving bag is erected, proper tension between the sides of the bag is generated at the top of the bag so that wrinkles do not occur.

The present invention relates to a fluid receiving bag having a rectangular front portion and a rear portion and a lower bottom portion attached to a lower portion thereof, which are sealed at each side, and a sealing area of a portion having a different sealing area at a middle portion of the side sealing portion of the front portion and the rear portion. Providing a fluid receiving bag, characterized in that it comprises a central sealing portion that is more widely sealed, to prevent wrinkles on the upper portion of the fluid receiving bag has the effect of making the brand name or brand name printed on the front surface to be noticeable to consumers . In addition, since the central sealing portion can be formed by the conventional manufacturing process, substantial cost reduction and improvement in work efficiency can be expected.
