Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging container in which a lid fitted to a container body can be easily removed.

[0002]

[Problems to be solved by conventional techniques and devices]

 BACKGROUND ART Conventionally, in a packaging container made of a synthetic resin sheet, various structures have been devised and proposed so that the lid body cannot be easily removed from the container body. When the items to be stored are foods, the lid is tightly fitted to the container body to prevent the contents from leaking as much as possible.For example, a concave part is provided at the peripheral edge of the lid. Thus, there is provided a packaging container having a structure in which the concave portion is fitted to the rim portion of the container body.

However, in this packaging container, since the recessed portion of the lid body is fitted into the rim portion of the container body, the tighter the fitting between the lid body and the container body, the further the container. The more rigid the main body and the lid, the more difficult it is to remove the lid once fitted. Then, this invention aims at providing the packaging container which can remove the lid body fitted to the container main body easily.

[0004]

[Means for Solving the Problems]

 As a configuration of a packaging container that can solve the above problems and achieve the purpose, a container body made of synthetic resin and a lid body made of a non-foaming synthetic resin sheet fitted to the rim of the container body are combined. The lid is characterized in that a tongue piece is formed on the outside of the fitting portion so that the tongue piece has a notch for incising a tear.

[0005]

[Action]

 According to the packaging container having the above-described configuration, the notch for notifying the tear provided on the tongue piece of the lid body in the state where the lid body made of the non-foaming synthetic resin sheet is fitted to the body body made of the synthetic resin. When the tongue piece is dissected from the tongue, the dissection is induced from the notch, and the dissection can be successively propagated, so that the fitting portion and a part of the lid body are dissected. As a result, the lip of the lid easily expands, the fitting between the lid and the container body becomes loose, and the lid can be easily removed from the container body.

【Example】

 Next, an embodiment of this invention will be described with reference to the drawings. 1 is a perspective view of a packaging container according to an embodiment of the present invention, FIG. 2 is a plan view of a main portion, and FIG. 3 is a sectional view taken along the line AA of FIG. The packaging container is composed of a container body 10 and a lid body 20, and in this embodiment, an example of a quadrangle or other square shape is shown as a whole.

The container body 10 is made of a synthetic resin, and the peripheral wall 12 is formed by bending the upper end of the peripheral side wall 11 outward in a U-shaped cross section. The lid 20 is formed of a non-foamed synthetic resin sheet, and has a concave portion 22 as a fitting portion formed on the peripheral edge portion 21 thereof in order to make the fitting and engagement with the container body 10 good. Therefore, it can be tightly closed in a closed state by fitting with the peripheral portion 12 of the container body 10.

Tongue pieces 30 are formed so as to project in the horizontal direction at the two corners on the diagonal line of the corners of the lid body 20 at positions outside the recess 22. The tongue piece 30 is formed with a substantially V-shaped notch 31 for guiding the tearing from the protruding tip to the base end side (in the vicinity of the recess 22). Therefore, the tongue 30 is divided into two small tongues 30a, 30a by the notch 31.

The operation of the packaging container 1 of this embodiment will be described. The concave portion 22 of the lid body 20 is fitted into the peripheral edge portion 12 of the container body 10, and the lid body 20 is covered with the container body 10 so that the fitting of both is tight (FIG. 3). See). When the lid 20 is removed, one of the small tongue pieces 30a, 30a divided by the notch 31 is grasped and held, and the notch 31 is used to spread the tear while separating the other small tongue piece 30a. It is possible to spread the crack C from the notch 31 to the peripheral side wall 20a across the recessed portion 22 and cut it (see FIG. 4). This facilitates widening the rim of the lid body 20, loosens the fitting between the lid body 20 and the container body 10, and allows the lid body 20 to be easily removed.

FIG. 5 is a plan view of a lid body according to another embodiment of the present invention. The packaging container of this embodiment shows an example in which the container body and the lid 25 are all formed in a circular shape. Although not shown, the lid 25 has a recessed portion as a fitting portion for fitting with the container body, and a tongue piece 30 is formed on the outside of the recessed portion so as to project in the horizontal direction. A notch 31 for incision guidance is formed in the tongue piece 30.

The packaging container of this embodiment also has the same effect as that of the above embodiment, and thus duplicated description will be omitted. In the packaging container of each of the above-described examples, the container body 10 is formed of a foamed or non-foamed synthetic resin material by a known molding method such as injection molding, vacuum molding, pressure molding or the like. For example, polyethylene, It may be molded of polystyrene, polypropylene, or the like, and may have strong rigidity, and in this case, the fitting with the lid 20 can be made more dense.

The lid 20 is formed of a non-foamed synthetic resin sheet, and is made of, for example, a polystyrene sheet, a high-impact polystyrene sheet, a polyethylene sheet, or the like by a forming method such as vacuum forming. If both the container body and the lid are made of non-foamed polystyrene sheet and the degree of fitting and fitting is high, the present invention can take advantage of the characteristics due to the split and spread, but it can be combined with other synthetic resin materials. Even in a container, it is possible to make full use of the feature of spreading the tears sufficiently and opening the lid well.

[0013]

[Effect of device]

 As described above, according to the present invention, the concave portion of the lid body made of the non-foamed synthetic resin sheet is fitted to the rim portion of the container body made of synthetic resin so that the lid body is covered in a dense state. However, since the lid is provided with a tongue projecting outside the recess, and a notch for guiding tearing is formed in the tongue, the notch crosses the recess and the lid is cut. The tear can be easily spread to a part of the peripheral wall, and the lid can be easily removed by loosening the fitting between the lid and the container body. Therefore, even if the degree of fitting of the lid is increased to close the lid more tightly, the lid does not become troublesome.

Further, since it is known that the lid has been opened by cutting the lid, it is possible to prevent reuse of the lid and help prevent tampering with the product.
