DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The wrap film adhesion coating container according to the present invention includes a container body and a lid. The container body has a structure in which the side wall is widened outwardly toward the upper opening, and a flange that fits the outer peripheral edge of the lid is formed on the opening edge. The shape of the upper opening is not particularly limited, and may be a polygon such as a triangle or a quadrangle, a circle, an ellipse, or the like. Although there is no restriction | limiting in particular in the magnitude | size of a container main body, The thing of the range whose maximum diameter of an upper side opening part is 5 cm-30 cm and depth is 2 cm-10 cm is preferable. The material of the container body is preferably a plastic sheet, but is not limited to this, and may be paper, a thin metal plate, or the like.
[0007]
In the lap film adhesion coating container according to the present invention, the opening of the container body is covered with a lid. The lid that covers the opening is formed with an outer wide flange portion along the outline thereof, and the vertical cross section in which the outer wall surface of the inner wall of the opening of the container body is closely fitted inside the wide flange portion is U. It is essential to have a structure in which a deep groove portion in the shape of a letter is formed, and an inner wide flat surface portion that is connected to the inner wall surface of the deep groove portion and substantially forms a flat surface with the outer wide flange portion is formed. .
[0008]
By forming the outer wide flange portion and the inner wide flat portion in a substantially flat surface, the lap film can be covered and adhered to both sides with a deep groove portion having a U-shaped vertical section . The “substantially flat surface” formed by the outer wide flange portion and the inner wide flat surface portion is not limited to a plane parallel to the bottom wall of the container body, and may have a slight level difference. It is meant to include those that are not parallel to the bottom wall but are flat when viewed macroscopically (see FIG. 4 to be described later) . The width of the outer wide flange portion and the inner wide flat surface portion can be selected in the range of 5 to 15 mm, depending on the size of the container body, the material of the lid, and the type of the wrap film.

The deep groove portion is formed between the outer wide flange portion and the inner wide flat surface portion, and the outer wall surface of the deep groove portion is in close contact with the inner wall of the opening portion of the container body, and the lid is fitted to the opening portion of the container body. It also functions as a guide groove for the wrap film breakage tool when tearing the lap film that has been tightly coated. If the depth of the deep groove is too deep, the wall surface of the deep groove will be too thin, and the strength when fitting and fixing the lid to the opening of the container body will be insufficient. Both are not preferred because they cannot immediately touch the bottom of the groove and break the wrap film. If the width of the deep groove is too narrow, it is difficult to provide the deep groove, and the wrap film cannot be broken because there is too much room for the wrap film to be stretched. The depth and width of the deep groove are preferably selected in the range of 5 to 10 mm.
[0010]
In the container according to the present invention, the opening of the container body is covered with a lid, and the wrap film in which both of them are tightly covered is in close contact with the lid, and the nail is applied to the wrap film breaking tool or the finger of the hand along the deep groove. Since the wrap film does not peel off when it is torn, the wrap film needs to be firmly attached at the outer wide flange portion and the inner wide flat portion provided across the deep groove portion. The lid that covers the opening is preferably made of a plastic sheet that adheres the wrap film. As such a plastic sheet, a plastic sheet containing no filler or lubricant is preferable, and examples thereof include polystyrene, polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, and polycarbonate. The lid can be easily manufactured from these plastic sheets by a vacuum forming method.
[0011]
The wrap film that covers the opening of the container body with a lid and covers both of them closely is not particularly limited as long as it is excellent in tackiness, polyvinylidene chloride film, polypropylene film, polyethylene film, polyamide film, The multilayer film etc. which laminated | stacked these films are mentioned.
[0012]
When the container for lap film adhesion coating according to the present invention is actually used as a food container, an article such as food is stored in the storage part of the container body, the opening is covered with a lid, and both are closely coated with a wrap film. do it. It is preferable to attach a tool for damaging the wrap film to an appropriate place on the surface of the lap film that has been tightly coated. The wrap film breakage tool is preferably a small piece such as a heart shape or a nail shape made of plastic or cardboard provided with a blade shape and a slightly pointed portion, and is preferably adhered by a double-sided adhesive tape. The adhering position is preferably in the vicinity of the label explaining the product of the lid. To break the wrap film, you can press the fingernail along the deep groove from the top of the wrap film to break it. What is necessary is just to push and break the pointed part from the top of the film along the deep groove.
