Packaging method, packaging device, packaging body and closure device for simple closure portion thereof

Abstract

The film sheet is bent into a U shape with the object to be packaged inside and the upper end of the U shape is sealed to form a central seal, and the film sheet is sealed at the front and back of the object to be packaged to form a top seal and a tail seal, thereby Reliably reduces creasing on top and tail seals. Provided is a packaging device in which a central seal is provided by sealing the upper end of a U-shaped film sheet (3), and a top seal and a top seal are formed by sealing the film sheet (3) at the front and rear of a packaged object (1). Tail seal, and be provided with before forming top seal and tail seal, the wrinkle removing device (18) that the part of film sheet (3) forming top seal and tail seal is stretched, and wrinkle removing device (18) ) before the action of pressing the film sheet (3) from left to right and shrinking the left and right width of the curved film sheet between the previous packaged object (1) and the subsequent packaged object (1).

Description

technical field [0001] The present invention relates to a packaging method, a packaging device and a packaging body thereof. [0002] Specifically, the present invention relates to a package suitable for packaging an object to be packaged (also simply referred to as a "package" in this specification and claims, etc.), a packaging method, and a packaging device thereof, such as a bread roll. A groove of a predetermined depth is formed on the top of the groove, and so-called "cooking bread" such as "fried noodles" or "sausage with lettuce" or "hot dog" or agricultural products such as "bush mushrooms" are sandwiched in the groove. Packaged objects that are packaged in contact with the film, or objects that do not want to be pressed inward by the film. In this specification and claims, a "film sheet" refers to a thin film sheet used for packaging objects to be packaged. Background technique [0003] The above-mentioned "yakisoba bread" will be described as an example. These "...

Problems solved by technology

[0011] In the packages described in Patent Document 1 and Patent Document 2, the cost of packaging becomes high, and for buyers, it is necessary to dispose of pallets, boxes, etc.

[0012] On the other hand, if the film sheet with low rigidity and thin thickness is used for packaging, in the case of "yakisoba bread", the appearance of the product will be damaged due to the adhesion of sauce, etc. to the inner surface of the film sheet. , and in the case where the packaged object is such as "Trichocarpus", the squeezed part is damaged due to the head of the main part of "Trichocarpus" being squeezed, and the value of the product decreases
