Description

The present invention relates to a sealing sheet for a flanged container.
More specifically, the present invention relates to a sealing sheet having a structure in which a flanged container formed from a lid and a container main body is sealed and cannot be resealed.

Conventionally, as a method for sealing a flanged container, a method of sealing only the lid part or the entire container including the lid part by shrink wrapping, and a method of sealing the lid part by a sealing seal or a fastener have been performed. .

However, in the method of sealing by shrink wrapping or sealing seal, when the flanged container is a lid without a screw structure, there is a problem that the sealing cannot be sufficiently performed and the shrink wrapping is broken during transportation. .
When the lid is sealed with a fastener or the like, it can be resealed, and thus fraudulent acts cannot be prevented.

On the other hand, as a method for collecting and packaging a plurality of flanged containers such as yogurt, a holder having a structure in which a cut portion is provided in a part of one sheet and the flange portion is inserted into the full cut portion has been proposed ( Patent Documents 1, 2, 3)

  However, these merely prevent the flanged container from falling apart, and it is not considered to seal a lid without a screw structure or to prevent illegal acts such as mixing of foreign substances.

Japanese Utility Model Publication No. 57-167061 JP-T-2004-538216 JP 2007-269334 A

The present invention has been made in view of the above-described background art, and an object of the present invention is to provide a sealing sheet that can easily seal a flanged container and prevent illegal acts such as contamination of foreign substances.

  The present invention was completed by having two cut portions for inserting a part of the flange portion at a specific position of one sheet. Furthermore, it was made possible to cope with various shapes of lids by appropriately providing a folding line in the upper fixing portion between the notches.

  According to the present invention, the lid portion can be easily sealed with a simple structure, and after opening, the sheet is easily disassembled or an opening mark remains, so that the sealing sheet is easily opened. Since it can be recognized, it becomes possible to prevent fraudulent acts such as contamination. Furthermore, the effect as a POP advertisement can be expected by performing various printings on the sealing sheet.

  Hereinafter, the best mode for carrying out the sealing sheet according to the present invention will be described in detail with reference to the drawings. However, it goes without saying that the present invention is not limited to the following examples.

Conventionally, in the food field, a holder for holding a plurality of flanged containers such as yogurt has been used. These have the structure which has the cut | notch part parallel to two places in the same sheet | seat like this invention. This is the same as the present invention. The differences between the present invention and the prior art are as follows.
When the sheet is placed on the container lid, the holder such as yogurt is locked with the flange portion slightly visible from the cut portion, and the entire upper fixing portion is in contact with the upper portion of the container lid. That is, when the holder is installed, the holder is not bent. In other words, it is in a flat state.
In contrast, the cut portion 2 of the present invention is provided closer to the center of the sheet than a holder such as yogurt. Therefore, when the sealing sheet 1 of the present application is installed in a container, after engaging the flange portion 6 with one of the notch portions 2 and then engaging the flange portion 6 with the other notch portion 2, It is necessary to lock the flange portion 6 to the cut portion 2 by pulling the end portion of the sheet that is not stopped. According to this positional relationship, a part of the sealing sheet 1 is brought into close contact with the side surface of the container, and a force is generated to cause the sealing sheet 1 to return to the original state, so that the container body 10 and the lid 11 can be fixed. .
On the contrary, the upper fixing part 3 is bent, but the cover part 11 can be pressed by using the bending to be an auxiliary tool for sealing (FIG. 1) or used as a POP advertisement. Yes (not shown).

  The shape of the sealing sheet 1 used for this invention will not be specifically limited if it has a width | variety wider than the diameter of a container. Considering productivity, it is desirable that the shape is square or rectangular.

  The material of the sealing sheet 1 used in the present invention is not particularly limited in terms of sealing properties as long as the purpose can be achieved, but in order to enhance the sealing function, a soft film as much as possible should be avoided. preferable. As long as it is in the form of a film, it may be a paper, polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyvinyl acetate, ABS resin, AS resin, acrylic resin, PET or other resin film, or laminated with these. Even things, rubber, etc. can be sealed. However, in the case of an elastic body such as rubber, it can be restored due to its properties, which is undesirable from the standpoint of preventing fraud.

  The thickness of the sealing sheet 1 used for this invention is not specifically limited. If it is too thick, it will be difficult to seal. 1 mm or less is generally desirable, and preferably 0.2 mm to 0.8 mm. More preferably, it is 0.3 mm to 0.5 mm.

Position of the cut saw portion 2 of the sealing sheet 1 used in the present invention, when is engaged to the flange portion 6 in the cut portion 2, it is provided in a state in which deflection occurs in the upper fixing portion 3 position. By providing at this position, a part of the sealing sheet 1 is brought into close contact with the side surface of the container and a force is generated to cause the sealing sheet 1 to return to the original position, so that the container body 10 and the lid 11 can be sealed. become.
Specifically, when the square 20S is created so as to be in contact with and included in the outer periphery 20 of the flange portion 6, it is desirable to provide two cut portions 2 on the inner side of the two opposite sides of the square 20S.
Furthermore, when the square 30S is created so as to be in contact with and included in the outer periphery 30 of the barrel portion 5 of the container to be sealed, the cut portion 2 is in contact with two opposite sides of the square 30S or outside thereof. When provided, the sealing seal 1 can be sealed in a form along the trunk portion 5 of the packaged container when sealed, so that it is more preferable.
More details are shown in FIG. The outer circle represents the outer periphery 20 of the flange portion 6, and the inner circle represents the outer periphery 30 of the body portion 5 of the container. The distance between the center lines of the cut portion 2 is X, the length of one side of the square 30S included in the outer periphery 30 of the container body 5 is Y, and the length of one side of the square 20S included in the outer periphery 20 of the flange portion 6 is set. When Z is provided, it is optimal that the notch portion 2 is provided so that the relationship of Y ≦ X ≦ Z is obtained, because sufficient sealing ability and a feeling of adhesion are obtained.
The container body 5 referred to here refers to the side surface of the container body under the flange 6 (FIG. 4A). In the case of the container as shown in FIG. 4B, the side of the main body of the container is substantially pointed below the inclined portion, not the inclined portion immediately below the flange portion. In the case of a container like FIG.4 (c), the side of the container main body under the flange part 6 is pointed out.

As described above, since the sealing sheet uses a force to return to the original state, the sealing sheet 1 is torn and peeled when the sealing state is released. Even if the end of the sealing sheet 1 is picked and peeled off so as to turn the seal, a part of the sealing sheet 1 is naturally damaged, so that it is understood that the sealing sheet 1 has been opened once.
Therefore, it is possible to prevent fraudulent acts such as mixing of foreign substances.

  The folding line 4 in the sealing sheet 1 used for this invention is not essential. It can provide suitably according to the shape of the cover part 11 of the container to seal. When the folding line 4 is not provided at all, it is in a bent state, but it can be used as a POP advertisement using that portion. In the case where the folding line 4 is provided, it is desirable to provide a plurality of folding lines 4 at positions that are substantially perpendicular to the cut portion 2 in accordance with the size and shape of the container because the sealing sheet 1 follows the lid portion 11.

The shape of the notch part 2 in the sealing sheet 1 used for this invention will not be specifically limited if it is a shape which can latch the container main body 10 and the cover part 11. FIG. Although depending on the thickness of the container body 10 and the flange portion 6 of the lid portion 11, it can be a straight line, a rectangle, or a substantially W shape (FIGS. 6D and 6E ).

  The length of the cut portion 2 in the sealing sheet 1 used in the present invention is appropriately adjusted according to the size of the flanged container to be sealed and the thickness of the flange portion 6 of the container body 10 and the lid portion 11 (FIG. 3). .

Hereinafter, specific examples of the present invention will be shown by way of examples, but the present invention is not limited to the present examples.

FIG. 2 is a plan view of the sealing sheet 1 of the present application. The sealing sheet 1 of the present application has a structure in which two substantially incised portions 2 are provided in a sheet-like material.
For example, when sealing a container made up of a lid 11 having a concave flange 6 as shown in FIG. 7 and a container main body 10, the flange 6 is connected to one notch 2 provided on the sealing sheet 1. Hook. In the state as it is, the other flange portion 6 cannot be hooked on the other cut portion 2. Therefore, in a state where the flange portion 6 is hooked on one of the cut portions 2, the other flange portion 6 is hooked on the other cut portion 2 so as to be pulled in the opposite direction, and the sealing sheet 1 is placed on the container body 10 body 5 side. Seal it so that it is bent. When sealed, the portion where the sealing sheet 1 is bent becomes a shape along the trunk portion 5 of the container body 10. At this time, the upper fixing portion 3 of the sealing sheet 1 bends, but if this is used to bend toward the concave portion of the lid portion 11, it can be used as an auxiliary tool for fixing the lid portion.
However, when the lid portion is convex, the upper fixing portion may be convex (not shown).

FIG. 8 shows a case where a container made up of a lid 11 having a concave flange 6 and a container main body 10 is sealed as in the first embodiment.
A folding line 4 is provided in the upper fixing portion 3 of the sealing seal 1 of the present invention. The folding line 4 can be provided as appropriate according to the shape of the lid 11. FIG. 5 shows a case where four main folding lines 4 are provided. Providing the folding line 4 is preferable because not only the appearance of the upper fixing portion 3 of the sealing sheet 1 is improved, but also the lid portion 11 can be pushed by the surface.

  FIG. 9 shows a case where a container made up of a lid 11 having a flanged portion 6 and a container body 10 is sealed. As in Example 2, it is used as it is (not shown in the figure) according to the shape of the lid, or provided with a suitable crease line.

  FIG. 10 shows a case where a lid 11 having a flange portion 6 having a flat top surface and a container consisting of a container body 10 are sealed. When the sealing sheet 1 of the present application is used, the upper fixing portion 3 is bent. By using this part, it can be used as a POP advertisement (not shown in the figure) or as a part for storing the bonus item 40.

Although the sealing sheet 1 has been described assuming a circular flanged container 12, the sealing sheet 1 may be substantially circular, and the object can be achieved even for an elliptical container.

The sealing sheet 1 used in the present invention can be used as a sheet for sealing a container having a flange portion 6. In particular, since the sealing property is high, even a lid without a screw structure can be sufficiently sealed. Since it is easily disassembled when opened, it cannot be resealed, and it is possible to prevent illegal acts such as contamination of foreign matter.
Moreover, it can also be used as a POP advertisement by utilizing the structure of the upper fixing portion.
