DESCRIPTION OF THE PREFERRED EMBODIMENT In order to facilitate an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and will be described in detail. Use unique language to clarify. Nevertheless, the scope of rights in this invention Any such modifications or other improvements to the illustrated apparatus, but are not intended to be limiting, and other possible applications of the principles of this invention as shown therein. It is understood that it is within the ordinary skill of those skilled in the relevant art.

Referring to FIG. 1, the male contour body 11, the ridge contour body 12, and An elevational view of the end of the tube 10 having ridges or ribs 15 for fitting is shown. be. An alternative to injection molding a tube of flexible plastic material such as 10 In particular, FIG. 10A shows a flexible structure having ribs 17 and contours 20 and 21 molded therein. An injection molded sheet of soft plastic material 16 is shown. flexible plastic Assuming that it is injection molded into a cylindrical structure as shown in Figure 1, this plastic The rack is flattened as shown in Figure 2 and cut into two pieces as partially shown in Figure 3. Cut off. This flexible plastic material is then folded as shown in Figure 4. , providing a bottom surface 22. Note that the bag in Figure 4 has two ends 25 and 26. be noticed. The sides 25 and 26 and the bottom 22 are all connected to the ends 27 of the sides and the bottom. They are sealed together as shown in FIG. Such sealing is accomplished by conventional methods using heat. and requires point sealing at 28. Here, the contour body is made of flexible plastic material. This gives it a thicker thickness than the rest of the material.

The flexible plastic material is what is known as "low density" polyethylene. approximately 2 mils (.002") thick. However, other flexible materials may be used if desired. Plastic materials can be used.

The folded and sealed bag 30 is then glued to the container 31 at its bottom 22. . As shown in FIG. 6, the bottom 22 of the bag and container 31 is notched at 32. You can put your hands inside the container. This type of notch is 7, so that when the contour bodies 11 and 12 are closed, the bond shown in FIG. This will seal @31. (i.e., between the container 31 and the bottom 22 of the bag) The cut is made between dashed lines 38 in FIG. 8). Resealable zipper of this invention - the structure can be marketed as part of the container 31 or separately; . The bag 30 may be heat sealed or glued to the container 31 at the factory, or it may be extinguished. It can be attached to existing bags purchased by consumers. Provide 30 bags to consumers If so, place the bag 30 in the container 31 until the resealable seal is attached. There is also a release sheet 35 for completely applying the adhesive.

FIG. 9 is a side elevational view of another embodiment of the invention. The embodiment shown in Figure 9 is an existing example. It is designed to be attached by the user to a container, as shown in Figures 9 and 0. As shown, it has a rib 40 and contour bodies 41 and 42. Both sides 45 and 46 of bag 47 are 5 They are sealed together at 0. This bag has both sides 45 and 46, respectively. The lower parts 51 and 52 have adhesive areas. Release sea 1, 55 and 56 are in the adhesive area. Cover each.

FIG. 11 shows the bag 47 after it has been attached to the container 57. This kind of installation is done with adhesive long enough to attach to areas 51 and 52 that have not yet been coated. It can also be done at a person with a ``Nemono''. In order to perform this kind of installation, it is necessary to parts 55 and 56 and glue the side parts 51 and 52 to the outer surface of container 57. do. Figure 11 shows the zipper in the installed position. Like the process shown in Figure 6 In addition, since the cuts are made on the side of the container throughout the gluing season of the bag 47, the bag 47 put it inside. The notch extends between dotted lines 48 so that it is within the adhesive area of the bag. Ru. As shown in FIG. 11, the bag 47 has contours 41 and 42 that close together. can be sealed. If you color the adhesive, you can cut it and place it inside the adhesive. It turns out that this is particularly effective in deciding where to go.

Referring now to FIG. 12, except that the bottom 60 of bag 6 is open, Another embodiment similar to that of FIGS. 9 and 1O is shown. Of course, the end of bag 61 Portions 62 (only one shown) are sealed. Thus, the location 60 at the bottom of the bag 61 Even if there is an opening in the container, the attachment part of the bag will surround the container removal opening, preventing air from entering. The bag can be glued to the container 57 in such a way that it can be taken in and taken out without the bag being removed. Of course Well, this also applies to the release sheet 6, as explained above with regard to Figures 9 and 10. 3 by removing and pressing the adhesive side of the bag against the container. It will be done.

Referring to FIG. 13, a further embodiment of the invention is shown. This example is , except that the adhesive is applied only to one side 70 of the side portion 71, as shown in FIGS. This is the same as the embodiment shown in FIG. When the release member 72 is removed from the portion 71, This part of the adhesive will be exposed, so you can attach the adhesive to the container. . The zipper seal shown in FIG. This is done through the adhesive surface rather than through the section 75. This procedure consists of contour bodies 77 and 80. When attached together, it ensures a proper seal.

One configuration with this structure is to attach a collar to the surface of the container 31 or 57. As a result, the user knows where to cut the opening. In this way, the target area disappears. positioned for the consumer. For example, a potato with a line indicating "cut here" There are bags currently on the market like chip bags. This bag can be used to close the bag and make potato chips. It also has a foil-shaped head for rolling and rolling to keep the contents fresh. Ru. The intended purpose for foils does not always work effectively. Because, If the foil is not held in the winding position by some effective means, the foil may unravel. This is because there is a tendency to These bags and other existing bags can be used to connect the seal to the existing container. The type of seal shown here can be used by simply adhering it to an object, making it resealable. I know what I can get.

This invention has many advantages. The first advantage is that it often replaces existing loading methods. The advantage is that there is no need for modification and the device can be used in conjunction with existing loading methods.

Another advantage is that the device is low cost. Yet another advantage is the ability to reseal The machinery and methods used to manufacture this container would need to be modified in order to There is no point. Another advantage of this invention is that by adding resealable properties Possible "leakage" is not created by this invention. The existing loading method As is, the bag can be made in the normal way, with resealable properties added later. manufactured and sealed.

Although this invention has been illustrated in the drawings and explained in detail in the foregoing description, the same invention is intended to be illustrative and textual. It should be understood that the term is not limited by the character. That is, only preferred embodiments are shown. What is described and all changes and modifications within the core of this invention are protected. It should be understood that
