Abstract

(57) [Abstract] [Purpose] The present invention has a sealing property, is easy to hold, can be opened easily, is convenient to take out little by little, and enables reopening that is not easily affected by humidity after opening. An object of the present invention is to provide a drawing paper container having a transparent lid. According to the present invention, a lid is composed of at least two layers, an inner layer and an outer layer, and a lower surface of the inner layer is processed with a thermoplastic resin capable of being heat-sealed with the main body of the container. A release agent was processed on the upper surface of the outer layer except for the partial openings, and an adhesive was processed on the lower surface of the outer layer. By bonding the inner layer and the outer layer,
The inner layer and the outer layer are bonded to each other in the partial openings, but the other portions are not sufficiently bonded due to the effect of the peeling agent, and the inner layer and the outer layer can be peeled off. When it is used as a lid, by making perforations or semi-cutting in the partial opening of the inner layer,
When the outer layer is peeled off, the partial openings of the layer are peeled off and the opening is made. The peeled outer layer retains weak adhesion to the inner layer, and thus can be resealed. A drawn-out paper container having such a lid.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing paper container in which a lid can be partially opened and reopened.

[0002]

2. Description of the Related Art A hermetically sealed container in which an opening of a cup-shaped paper container is heat-sealed with a lid is widely used for beverages and the like. The lid for sealing the opening is important not only for sealing the contents but also for ease of opening. If the contents are liquid, it is generally used to pierce the straw, or to open a straw hole in advance and seal it with a label etc., peel off the label when using, and insert the straw. . For contents other than liquids such as confectionery and snacks, a paper container is generally structured such that a lid is hermetically sealed at the opening of the container and the lid is peeled off and opened over the entire surface.

[0003]

In the above-mentioned container, emphasis is placed on peeling and opening and does not have the function of resealability. Moreover, since all the opening portions of the container are opened and not resealed, the container is easily spilled, which is inconvenient in a traveling vehicle or the like. In addition, there is a problem that when the contents which do not like humidity are eaten little by little instead of being eaten at once, they are easily affected by humidity. Therefore, the present invention has a hermetically-sealed, easy-to-hold, easy-to-open, convenient to take out little by little, and a resealable paper container having a resealable lid that is not easily affected by humidity after opening. It is intended to provide.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a lid is composed of at least two layers, an inner layer and an outer layer, and a lower surface of the inner layer is provided with a container body. The thermoplastic resin that enables heat sealing is processed, and the upper surface of the inner layer is processed with a release agent in a portion to be peeled off except the partial opening, while the lower surface of the outer layer is processed with an adhesive. . By bonding the inner layer and the outer layer,
The inner layer and the outer layer are bonded to each other in the partial openings, but the other portions are not sufficiently bonded due to the effect of the peeling agent, and the inner layer and the outer layer can be peeled off. When it is used as a lid, by making perforations or semi-cutting in the partial opening of the inner layer,
When the outer layer is peeled off, the partial openings of the layer are peeled off and the opening is made. The peeled outer layer retains weak adhesion to the inner layer, and thus can be resealed. A drawn-out paper container having such a lid.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention described above will be described in detail below. As shown in FIG. 1, the container of the present invention comprises a main body 10 and a lid 1 heat-sealed to a curl portion 11 provided in an opening.

The main body 10 is a cup-shaped container having a round shape,
There are prismatic shapes. Materials mainly made of paper include inner surface polyethylene processed paper, double sided polyethylene processed paper, wax processed paper, water resistant paper, oil resistant paper and the like. Further, a laminated body in which aluminum foil or the like is attached may be used. Further, the material is not necessarily paper and may be made of plastic. For example, polypropylene, polystyrene, polyvinyl chloride, or a composite material mainly containing these plastics can be used.

The lid 1 is composed of an inner layer 2 and an outer layer 3, as shown in FIG.

The base layer 4 of the inner layer 2 may be a simple substance such as paper, an aluminum foil, a plastic film or the like, or a composite thereof. The inner surface adhesive layer 5 is made of a material having good adhesiveness to the main body 10, such as polyethylene, polypropylene, EVA,
Thermoplastic resins such as polystyrene, polyester, and mixtures thereof are used and processed by coating, extrusion coating, film laminating and the like. The release layer 6 is partially processed into the base material layer 4. As a material, silicone resin, polyamide resin, chlorinated polypropylene resin, or the like is used as an ink. Other,
Nitrocellulose resin, rubber resin, polyvinyl chloride resin, acrylic resin, etc. to which silicone, paraffin wax, stearic acid, etc. are added can also be used.
Gravure printing is the most suitable processing method. In addition, flexographic printing, offset printing, screen printing, etc. can also be used.

The base material layer 7 of the outer layer 3 may be a simple substance of paper, an aluminum foil, a plastic film, or a composite. It is preferable that it has a relatively high tensile strength. For the adhesive layer 8, a pressure sensitive adhesive is used. There are adhesives such as acrylic resins, rubber resins, and polyamide resins. The protective layer 9 is a layer provided on the surface of the base material layer 7, and is formed by sticking a transparent plastic film or applying an OP varnish by printing. The printing of patterns, characters, etc. is performed on the back surface of this transparent plastic film or on the surface of the base material layer 7.

The lid 1 and the main body 2 having the above-mentioned structures are joined together to form a sealed container. The opening function of the lid will be described. As shown in FIGS. 2 and 3, when a cut is made in the inner layer 2 at the root portion of the tab 20 and the tab 20 is pulled up, as shown in FIG.
The outer layer 3 is peeled off while being in close contact with the curl portion 11. When reaching the partial opening 22, the peeling property between the inner layer 2 and the outer layer 3 is lost, and the partial opening 22 provided with a cut or perforation around it is peeled off to achieve the partial opening. It After that, although the entire outer layer 3 may be peeled off, as shown in FIG. 3, the peeling property disappears at the boundary 24, and the outer layer 3 remains adhered to the inner layer 2 at the partially non-peeling portion 26. Exfoliated part 2 of outer layer 3
Since the adhesive strength of 5 remains, it can be resealed.

[0011]

As is apparent from the above description, in the sticker-type sheet-fed paper container of the present invention, the outer layer of the lid composed of two layers, the inner layer and the outer layer, can be easily peeled off, and by peeling, the inner layer The partial openings that have not been processed with the release agent are peeled off at the same time, and the openings are formed. Moreover,
The peeled outer layer can be resealed. The partial opening makes it convenient to take out solid or powder contents such as confectionery and snacks little by little, and by resealing it, it can be used in running vehicles. It does not spill, is safe and hygienic, and is less susceptible to humidity after opening, so the storage period after opening becomes longer.
