Description

[Detailed description of the invention] This invention relates to an easy-to-open resealable container that can be easily manufactured from a single piece of material such as paperboard.In particular, two parallel half-blanket lines are formed from the back side on the unsealed part of the material. The present invention relates to a seal-type resealable container characterized by being provided with a zipper formed by perforating the zipper and having completely open perforations on both sides of the zipper.

Among conventional containers of this type, there are resealable seal-type containers that have separate lids and body members, but there are no seal-type resealable containers that are formed from a single piece of material. In addition, there are conventional opening devices that have a simple perforation, two parallel perforations, or half-perforated lines on both sides of the material. In either case, there was a problem with the strength of the opening device, and if the package was made to be easy to open, the strength would be low and it would be easy to tear, whereas if the strength was increased, it would be difficult to open.

In view of the above points, the present invention is a seal-type resealable container that can be made from a single piece of material and is made easy to open by appropriately combining perforations and half-blanking lines, A detailed description will be given below based on the embodiments shown in the drawings.

(However, an example of a cylindrical container will be described.

) First, as shown in Fig. 1, the container of the present invention is made of a substantially rectangular material including an exterior part 1 and an interior part 2 whose height is slightly lower than that, and there are glued parts at the left and right ends of the exterior part 1. 3 is provided on the back side of the paper, and the glued part 4 is provided on the front side.

Similarly, attach the glued parts 5 to the left and right ends of the interior part 2 on the back side of the paper.
Gluing portions 6 are provided on each front side.

Furthermore, 2
Half-cut lines 9, 9 of the book are punched on the back side of the material at a position slightly lower than the upper end of the interior part 2, and the half-cut lines 9, 90 are both outside and almost parallel to the half-cut lines 9, 9. Perforation 8,
8 to form an opening zipper 10.

As a result, the exterior part 1 is divided into a lid part A and a body part C, and a knob piece 7 that is partially connected to the half-cut lines 9 is provided in series at the side end of the opening zipper 10.

As described above, the interior portion 2 has its upper end at a position higher than the opening zipper 10, and therefore the lid fitting portion 12 is formed in the portion of the interior portion 2 that is higher than the opening zipper 10.

In this case, as shown in FIG. 3, the outer part 1 is connected to the upper end of the inner part 2' with the same width as the inner part 2' via the partial joining line 11.
If the inner lid parts a are arranged in series so that they are at the same height, when a container is formed, both the lid part and the body part can have a double structure.

Furthermore, if the lower end of the inner part 2 is made higher than the lower end of the outer part 1 and a step 13 is formed, it becomes easier to fit the bottom member 14 and fix it by seaming, as will be described later.

The above-mentioned material is rolled up using an appropriate method to form glued parts 5 and 6.
, 3 and 4 are adhered one after another to form a cylindrical body, a lid member 15 and a bottom member 14 are respectively fitted into the upper and lower open ends and fixed by seaming or the like to form the container of the present invention.

(See Figure 4) When opening the container of the present invention, if you pull the tab piece 7, the material will tear at the half-perforated lines 9 and 90, and if you pull it even harder, it will tear along the outer perforations 8°8. The opening zipper 10 is removed.

As a result, the exterior part 1 is separated into the lid part A and the body part C, and becomes ready to be opened. However, the exterior part 1 is stuck to the outside of the interior part 2, and after opening, the interior part 2 is separated from the exterior part 1. It is in a slightly more prominent state.

(See Figure 5) Since the present invention has the above-described structure, even though the opening zipper is easy to open due to the half-cut line, the outer side of the zipper is easy to open due to the joint of the perforations. Because "lid part A" and "container part C" are connected, during storage,
The bag is prevented from being opened inadvertently during transportation, and has a double structure of an interior part and an exterior part, and since the interior part 2 is slightly protruded from the exterior part 1, it can be resealed in a seal style.

Moreover, since it can be made from a single piece of material, it is an excellent container that is easy to manufacture and has the advantage of being low in cost.

In the above embodiments, the case of a cylindrical container has been described, but it goes without saying that the same effect can be obtained in a rectangular cylindrical container or the like.
