JPH0199965A - Opening retainer in bag with zipper - Google Patents

Abstract

PURPOSE:To enable the opening to be kept open without manual operation, by turning the content take-out port outward below the zipper, and by locating it outward to retain open state. CONSTITUTION:The content is filled into the storage 1 through an opening 3, and the top of zipper 4 is heat-sealed. For example, before the bag is directly put in a microwave oven, the seal and zipper 4 are opened and the neck 2 is erected. Steam and air evolved from the content escape through the zipper 4 with the result that swelling of the bag is prevented. In this case, when the content is a fluid such as porridge or risotto, the load of the content is displaced toward the center of the bag, and stress generates to the bottom in the direction of opening to both sides. When the zipper 4 is to be left open and the opening 3 opened wide, its edge of is turned outward below the zipper 4 to locate it outside. The opening 3 is left open by the elastic action of the zipper 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is directed to forming a content storage part horizontally (flat), and extending a content outlet with a zipper in a vertical direction from the center of the content storage part. This invention relates to an inverted T-shaped zippered bag formed with a raised neck.

[Prior Art] Fig. 6 shows a perspective view of a conventional inverted T-shaped bag. An opening part (take-out port) 3 with a zipper 4 is formed in the raised neck part 2, and a space with a T-shaped cross section is formed inside.

[Problems to be Solved] Since the opening 3 of the above-mentioned conventional bag is raised, for example, it is difficult to fill the bag with liquid or liquid-rich food and place it on a table without spilling. It has the characteristic that it will not spill even if placed directly in the microwave.

In addition, by attaching a closing means such as a zipper 4 inside the opening 3, the product can be stored in a sealed state, or the zipper 4 can be partially or completely opened to allow steam and air to escape from inside. This allows, for example, to heat frozen foods directly in the microwave while still in the bag.

However, on the other hand, I took the bag out of the microwave.

When taking out the contents from the opening 3, the opening 3 acts in the closing direction due to the elastic action of the zipper 4 inside the opening 3, and when taking out the contents, the opening 3 must be opened with one hand each time. The problem is that it doesn't.

The present invention has been proposed in view of these points, and it is an object of the present invention to propose a zippered bag that can be opened without having to manually open each zippered opening.

[Means for Solving the Problems] As a means for solving the above problems, the present invention proposes a bag having the following configuration.

A bag with a zipper in which a content storage part is formed horizontally and a content removal port with a zipper is formed in a neck part vertically raised from the center of the content storage part. An opening maintaining device for a bag with a zipper, which is turned outward below the zipper, and the zipper is positioned on the turned outside to maintain the open state.

[Function] In the above-mentioned bag, the opening is turned outward below the zipper, and the zipper is positioned on the outside. The amount of turning over is arbitrary; turning over more will get you closer to the contents, and turning over less will move you further away, but for example, if you are stirring the contents with the contents in the bag, it is advantageous to have a higher opening to prevent spills. be.

[Example] Fig. 1 is a perspective view of a bag according to the present invention, and this bag has a contents storage part l whose plane is approximately hexagonal and has an eccentric shape;
An opening (takeout port) 3 with a zipper 4 is formed in the neck 2 rising from the center of the content storage part 1, and an inverted T-shaped gap is formed in the internal cross section.

In addition, the four corners are cut 5 in a straight line as shown in Figure 1.
This may be heat sealed 6 or may not be cut as in the conventional example.

The above-mentioned bag is filled with the contents from the opening 3 into the contents storage part 1, and sealed by heat-sealing the upper part of the zipper 4. For example, when the bag is to be placed directly in a microwave oven, the seal is opened, Open the zipper 4 completely or partially, and place it in the microwave with the neck 2 upright. Water vapor generated from the contents and air inside the expanded bag escape through the opening of the zipper 4, thereby preventing the expansion pressure of the bag.

When heating is finished, lift the neck 2 with your hand and take it out of the microwave.

At this time, if the contents are liquids or fluids such as rice porridge or rigid, the four corners of the contents storage part l are cut, so the load of the contents is shifted to the center of the bag, and the load on both sides is Stress is generated in the direction of escaping from the bottom and opening on both sides with respect to the bottom. FIG. 3 shows this state.

If you want to open the zipper 4 and open the opening 3 wide, as shown in FIG.
Position 4. In this case, due to the elastic action of the zipper 4, the zipper 4 becomes a bone, and the opening 3 remains wide open. Take out the contents,
You can stir it in this state. Of course,
This can also be done when filling the contents into the bag.

[Effects of the present invention] As described above, the present invention provides an inverted T-shaped bag with a zipper, by turning the opening outward and using the zipper as a rib, so that the opening remains wide open. The state can be maintained. As a result, it is convenient to stir the contents inside the bag and take out the contents from inside the bag, and it is also very convenient for instant food because it can be eaten as is without taking out the contents on a plate etc. It is.
