Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention uses a thermoplastic sheet to connect a plurality of molding containers for storing contents such as confectionery or soap in a row in a row. , Attach a common lid material to this, 1
Made so that it can be manufactured, transported, and stored as individual packages,
Further, the present invention relates to a collective package of molded containers which enables easy separation of individual containers at the time of sale or use.

[Prior Art] Conventionally, a collective package in which a plurality of containers made of plastic molded products are overlaid with a common lid member made of a sheet of paperboard or aluminum or a plastic sheet or the like and adhesively sealed is used as a food product. Widely used for packaging medicines.

However, the above-mentioned conventional collective package has a common lid member made of paperboard, laminated paper, plastic sheet, or the like fixedly attached to the molded container, so the container is opened and the lid member is removed from the container when the contents are taken out. There is a drawback that it takes time to peel it off. In addition, since the lid material is difficult to peel off, the container body and other lid portions may be damaged during opening, and the opening may not be cut cleanly. Therefore, there is a problem that the sealing effect of other containers is lost, or that individual containers cannot be after-used as resealable containers.

Furthermore, in general, this type of collective package has a weak connection strength of individual containers, and there is a risk that the connection part may be broken during transportation. Therefore, when packing two or more containers, use a thick cover material. There is also a drawback in that the packaging cost is correspondingly increased due to the construction, the use of trays and other auxiliary tools, and the wrapping with shrink film to reinforce the whole.

The present invention is intended to solve the above-mentioned problems, and it is easy to cut and open individual containers so that they can be opened neatly, and individual containers can be resealed after cutting. It is intended to provide a collective package of molded containers that can be after-used as a possible container.

[Means for Solving the Problems] In order to achieve the above object, the present invention is a plastic in which a plurality of containers for storing contents are connected in a row in a row and a flange is stretched around the outer periphery of each container. Two members: a base member made of a molded product, a plurality of bulging molded parts fitted and fixed on the container and a lid member made of a plastic molded product stretched with a flange around the bulged molded parts. Consisting of the base material and the lid material, both of which are overlapped with each other, and the flange surfaces thereof are abutted with each other, except for the flange surfaces sandwiched between the individual containers, and the abutted flange surfaces are adhered to each other, and A cutting means was provided between the containers and between the bulging molding parts by perforated cutting lines, etc., and similar cutting means was also applied to the inside along the adhesive parts to obtain the intended collective package. It is a thing.

[Embodiment] Next, the present invention will be specifically described with reference to the illustrated embodiment.

FIG. 1 shows an example of accommodating contents (objects to be packaged). A common lid member 2 made of a transparent molded sheet is put on a base member 1 in which three tray containers 11 are connected in a row in a row. , Showing a collective package formed by adhesively sealing the outer periphery thereof.

The base material 1 is made of PE, PP, as shown in FIGS.
A tray container 11 of an appropriate shape (an ellipse shown in the figure) formed by heating a thermoplastic sheet such as PV by an appropriate forming means such as vacuum forming, pressure forming, press forming, etc.
3 are continuously provided in one direction, and a flange 12 is integrally formed on the outer circumference of each container. Further, a concave portion 13 is formed on the flange surface sandwiched between the individual containers, while
A rib-shaped projection 14 is provided on the outer periphery of the container except the flange surface.

As shown in FIGS. 5 to 7, the lid member indicated by reference numeral 2 is
A plurality of bulging parts 15 corresponding to each tray container 11
Are continuously provided in one direction, and a flange 16 that is abutted with the flange 12 is integrally provided on the outer periphery of the bulging molding portion. Further, the flange 16 is provided with a recess 17 into which the rib-shaped projection 14 is fitted. The lid member 2 configured as described above is formed by heating a thermoplastic plastic sheet and subjecting it to vacuum forming, pressure forming, or press forming, similarly to the base member 1.

According to the present invention, after the contents are placed on the base material 1 made of the plastic molded product constructed as described above, the lid material 2 is piled up as shown in FIG. After fitting the extrusion molding part 15 and abutting the flange surfaces with each other, the recess 17 fitted with the rib-like projections 14 of the remaining abutted flange surfaces excluding the flange surfaces sandwiched between the individual containers. And are fixed by any adhesive means such as heat seal, cold seal, and hot melt adhesive. The flange surface sandwiched between the individual containers is the non-adhesive portion as described above. Further, between the containers 11 and 11 and between the bulging molding portions 15 and 15, a cutting means such as a perforated cutting line 19a is provided, and on the inner line along the seal portion 18 of the flange surface, the same as above. The cutting line 19b is applied. In this way, the collective package as shown in FIG. 1 is manufactured, and the product is transported, stored or sold in such a packing form. After the sale, when opening the individual containers and taking out the contents, the seal portion 18 is cut off along the perforated cut lines 19b, and the individual containers 1 are cut along the cut lines 19a.
Separate one from the other. In this case, as shown in FIGS. 9 to 10, the individual containers can be subdivided with good appearance in a state where the individual containers are covered.

As shown in FIG. 11, each container 11 after subdivision is composed of an individual container body 20 and a fitting lid 21 that are fitted together in the form of a cage, so that the contents can be taken out by removing the fitting lid. Even after the contents are taken out, it can be used afterwards as an independent small container with a lid.

Note that, as described above, the shape of each container is not limited to the oval shape shown in the drawing, but may be any shape such as a circle or a polygon.

[Effects of the Invention] As described above, in the collective package of the molded containers according to the present invention, the outermost peripheral portion is sealed, and the cutting means is provided inside the sealing portion, so that the containers can be easily separated. Also, when taking out the contents from the container, the lid material and the base material are only adhesively sealed on the flange surface outside the cut portion, and since the individual containers are non-adhesive portions, the opening is easy. When opened, there is no risk of damage to the container body or the lid, and it can be reused as a sealed container with a lid afterwards. Further, according to the present invention, it is a useful idea in that a plurality of molded containers can be easily obtained at a low cost by using a smaller amount of packaging material and easily for transportation and sale.
