Abstract

PROBLEM TO BE SOLVED: To provide a packaging container capable of being simply unsealed by single manipulation. SOLUTION: A packaging container has a container main body 1 containing foodstuffs, and a top end opening 2 of the main body 1 is sealed with a plastics film 3. A unsealing tape 4 having a narrow width is fixedly provided on the film 3, ranging from one end of the film to the other end thereof. Cut lines 6 are formed in the film 3 with unsealing end parts 4a, 4b of the tape 4 therebetween, respectively. The cut lines 6 are provided in order to easily hold the end parts 4a, 4b of the tape 4 with user's fingers and to make the unsealing of the film 3 easier. Further, in the case where a uniaxially or biaxially oriented film is adapted as the film 3, the tape 4 is preferably fixed to the film 3 along a direction in which the film 3 is oriented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for containing and sealingly packing sandwiches, castella, sugar toast, and other various foods.

[0002]

2. Description of the Related Art Conventionally, for packaging, for example, when a food product such as a sandwich is displayed at a store and sold, a desired food product is stored in a plastic container body, and the upper end opening of the container body is made of a plastic film. BACKGROUND ART Packaging containers that are sealed and packaged and sold in that state are generally known. This type of conventional packaging container generally employs a means in which a plastic film of a predetermined size is placed on the upper end opening of the container main body and sealed by heat sealing along the periphery of the opening of the container main body.

[0003] By the way, the purchaser of the product opens when eating the contents. As described above, the plastic film is welded and sealed with a heat sheet along the periphery of the opening of the container body. Therefore, there is a problem that the film cannot be easily peeled off from the container body. Further, when a strong force is applied when the film is peeled off, the container body may be deformed and the contents may be crushed.
Furthermore, when a notch (cut) is provided at the end of the heat-sealed film and a means for tearing the film from this portion is adopted, the film must be operated to tear accurately along the stretching direction, or the film may be broken. It may be cut off on the way.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a packaging container which can be easily and orderly opened by one-touch operation.

[0005]

In order to achieve the above object, one of the inventions (first invention) of the present invention accommodates food in a container body and seals an upper end opening of the container body with a plastic film. In the above-mentioned packaging container, a narrow opening tape is fixedly provided from one end of the film to the other end thereof. Further, another one invention (second invention) of the present invention includes a plurality of container bodies,
In a packaging container in which the upper end outer portions are connected and arranged side by side to accommodate food in each of the container main bodies and seal the upper end opening of each of the container main bodies with one piece of plastic film, another one end of the film is used. The present invention is characterized in that a narrow opening tape is fixedly provided on the end.

According to the first and second aspects of the present invention, the plastic film can be easily and neatly cut along the tape by pulling the opening end portion of the opening tape with a finger and pulling it. .

[0007] In the second aspect of the present invention, a cut line for controlling tearing, which is orthogonal to the tape, may be provided on the film at the connecting portion of the container body, including the tape. See claim 3). When this configuration is adopted, when the portion of the opening end of the tape is pinched and pulled, the film is cut along the tape, and the cutting stops at the position of the cut line. Therefore, only one of the plurality of container bodies can be opened, and the remaining container bodies can be held in a sealed state.

In the present invention, the film may be provided with a cut across the opening end of the tape (see claim 4). When formed in this way, the opening serves as a guide for tearing, so that the opening operation is further facilitated. Further, in the present invention, a configuration in which the opening end of the opening tape slightly protrudes from the end of the plastic film can be adopted (see claim 5). When formed in this manner, the opening end of the tape can be easily picked up, so that the opening operation can be performed more easily as described above.
