BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for mainly storing foods and the like.

[0002]

2. Description of the Related Art Conventionally, in a cup-shaped packaging container used for foodstuffs containing water as a content, for example, miso, yogurt, etc., a flange-shaped portion formed on the periphery of an opening of a container body is used. There is also known a structure in which a heat-sealable sheet is used as an inner lid for a main body, and the inner lid is heat-sealed for sealing, and a synthetic resin upper lid (outer lid) is fitted thereon.

The means for fitting the upper lid to the container body is as follows:
A method in which a curved portion that embraces a curved portion obtained by curving the outer peripheral edge of the flange portion of the container body slightly downward together with the sheet of the inner lid slightly protruding from the curved portion is provided on the peripheral edge of the upper lid and fitted. Has been taken.

[0004]

In such a conventional method, if the fitting of the curved portion of the top cover is loose, it is easy to detach from the main body during handling such as transportation and display, and if it is too tight, the top cover will not be attached at the time of mounting. Since crushing, deformation, and breakage are likely to occur, which impairs the commercial value, high precision is required in molding and the cost is high. Since various materials are used for the sheet of the inner lid that is heat-sealed to the flange-shaped portion, it is necessary to calculate the thickness of the inner lid sheet.

[0005] In addition, it is conceivable to apply shrink coating without securely fitting, but also in this case, there is a problem that the packaging process is increased and the cost is increased. An object of the present invention is to solve such a conventional problem and to provide a packaging container having various effects described later.

DISCLOSURE OF THE INVENTION The present invention has been made to achieve the above object, and has an upper peripheral flange portion of a synthetic resin upper surface open type container body sealed with a closing sheet, and the closing sheet. Cover the upper surface with an upper lid, so that the upper lid and the closing sheet can be peeled off , and the upper lid is
So that it can be fixed while maintaining close proximity to the obstruction sheet surface
The packaging container is formed by adhering dots in a transparent hot melt adhesive .

In the present invention, it is preferable that the obstruction sheet is provided with a display of contents or other necessary printing on the surface, and the top cover is made of a transparent synthetic resin so that the printing can be seen through.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the container of the present invention, and FIG. 2 is a plan view of the embodiment. Reference numeral 1 denotes a cup-shaped synthetic resin container body made of polyethylene, polypropylene, a synthetic resin laminate, etc., 1a denotes an upper peripheral flange, 2 denotes, for example, a closing sheet in which paper, an aluminum layer, a polyethylene layer, etc. are integrally laminated, 3 Denotes a sealing portion of the closing sheet, 4 denotes an upper lid, 5 denotes a dotted bonding portion between the lower surface of the upper lid and the upper surface of the closing sheet, and 6 denotes a printing portion.

The closing sheet 2 can be heat-sealed to the container body 1, for example, a composite sheet such as a polyethylene terephthalate layer, a paper, an aluminum layer, a polyethylene terephthalate layer, a polyethylene layer laminated in order from the upper layer, and other non-water-permeable sheets. Made of laminated sheet
The upper peripheral flange 1a is heat-sealed. The point-like adhesive portions 5 are usually filled with the contents and sealed with the closing sheet 2 and then provided at several places (four places in this embodiment) on the upper surface of the sheet.
Is dispersed at appropriate intervals, EVA-based, polyethylene-based, polyamide-based adhesive, and other transparent molten viscous hot melt adhesive and the like is applied to one place about 2 to 8 mm in diameter, and then The upper cover 4 is provided on the upper surface and fixed by pressure bonding. The number, position, and shape of the bonding portions 5 can be appropriately set as needed.

The upper lid 4 is bonded in a dotted manner at a plurality of locations with a transparent hot melt adhesive, is fixed in a state of being close to the surface of the closing sheet, and is printed on the upper surface of the closing sheet 2. And other indications have a good appearance without hindrance and are reliably protected. Therefore,
Since the upper lid 4 does not necessarily have to have a structure in which it is securely fitted to the container main body 1 at the peripheral edge, and is easy to attach,
Productivity is improved. In addition, there is no risk of detachment during transportation or storage. In addition, when fitting at the peripheral edge, it was necessary to increase the rigidity of the peripheral edge of the upper lid in order to prevent breakage of the upper lid, etc. It is no longer necessary to provide rigidity, so that the thickness of the upper cover sheet can be reduced, and the manufacturing cost can be reduced.

In use, the upper lid 4 is detached by several points, so that it can be peeled off by hand. Also, once removed, the printed surface of the adhesive portion of the closing sheet is damaged, so it can be seen that the top cover has been opened, which is significant in securing the virginity of the product.

[0012]

As described above, the packaging container of the present invention, as a miso or other cup-shaped packaging container, is particularly simple to manufacture because the upper lid does not require high precision, and the cost is reduced. When filling the contents, the cover operation is easy, and the package after filling the contents has no risk that the top cover will be detached during transportation or other handling, and it is easy to manage the store, and the contents can be easily stored. In use, the effect is large, such as easy removal of the top lid and easy use.
