Description

  The present invention relates to a container with a lid formed of a paper sheet whose main material is paper.

  Conventionally, resin-based containers have been used exclusively for packaging granular gums, supplements, chocolates and the like. This is because the resin-based container is excellent in terms of functions such as initial sealability, recloseability, and water vapor barrier properties.

  In addition, this type of container is configured so that the opening of the container body can be repeatedly opened and closed with a lid. Generally, both a container main body and a lid (for example, refer to Patent Document 1) are connected and integrated after being molded with resin.

  The lid includes a disk-shaped upper lid, a tear ring that hangs from the periphery thereof, a fixing ring that hangs from below the tear ring, and a hinge that connects the upper lid to the fixing ring. The tear ring functions as a pilfer proof portion, and is connected to the upper lid and the fixing ring via an annular thin portion. The hinge is provided so as to cross the tear ring in the vertical direction. In addition, an annular protrusion that fits into an annular groove formed on the outer peripheral surface of the container body is formed on the inner peripheral surface of the upper lid, and a thin annular hanging wall is provided on the ceiling surface of the upper lid.

  The lid is put on a container main body filled with contents such as granular gum, and the fixing ring is fitted around the opening of the container main body to be integrated with the container main body. Moreover, the annular protrusion of the upper lid fits into the annular groove of the lid body to seal the inside of the container body.

  The container can be opened by the user tearing and removing the tear ring from the lid, and the container body is opened by opening the lid so that the annular projection on the upper lid is detached from the annular groove of the lid body. Is released. The lids are connected by hinges and try to close the opening of the container body by the elastic force of the hinges, but the annular thin part abuts the opening edge of the container body and prevents the lid body from returning to the closed position. The lid is held in the open state. As a result, the user can easily take out the contents from the container body. After the user takes out the contents, if the lid is put on the container body and pressed, the annular protrusion of the upper lid fits into the annular groove of the lid body, and the container body is sealed again.

  Moreover, a paper cup (for example, refer patent document 2) may be used for packaging of the granular content. In this case, after filling the paper cup with granular contents, the paper cup is sealed by adhering a lid sheet such as an aluminum foil to the opening edge of the paper cup. The user can peel off the lid sheet from the opening edge of the paper cup and take out the contents from the container body.

  Since the above-mentioned conventional resin-based containers are made of resin, recyclability, light shielding properties, and the like have come to be regarded as problems. Since the paper cup is made of paper, the disadvantages of the resin-based container are small, but there is a problem that it does not have resealability and lacks the storage stability of the contents.

  In addition, the resin-based container can be closed again with the lid even after opening, but when the lid is opened, the lid tends to self-close by the elastic force of the hinge, so it is difficult to take out the contents. There is a problem. Therefore, it is necessary to separately provide a thin annular hanging wall as described above and keep the lid open.

  The best mode of the present invention will be described below with reference to the drawings.

<Embodiment 1>
As shown in FIGS. 1 and 2, the container with a lid includes a container body 1 and a lid body 2 that opens and closes an opening of the container body 1.

  The container main body 1 is formed by winding a paper sheet mainly made of paper into a cylindrical shape, and overlapping and bonding both ends thereof. In addition, it can be formed by a spiral tube obtained by winding a paper sheet in a spiral shape. The container body 1 can also be formed in a tapered or inversely tapered cylindrical shape.

  As the paper sheet, for example, one having the following layer structure can be used.

  In the layer configuration, the first layer is the surface side of the container body, and the last layer is the inner surface side of the container body. When a paper sheet is wound into a cylindrical shape and bonded at both ends, for example, the innermost layer and the outermost polyethylene resin layer of the paper sheet are used as a thermal adhesive.

  Polyethylene resin layer / paper layer / polyethylene resin layer, polyethylene terephthalate resin / paper layer / polyethylene resin layer, polyethylene resin layer / polyethylene terephthalate resin / paper layer / polyethylene resin layer, high density polyethylene resin layer (film) / polyethylene resin layer / Paper layer / polyethylene resin layer, expanded polyethylene resin layer / paper layer / polyethylene resin layer, polypropylene resin layer / paper layer / polypropylene resin layer, polyethylene resin layer / paper layer / polyester resin layer, polyester resin layer / paper layer / polyester resin Layer, polyethylene resin layer / paper layer / ethylene-acrylic acid copolymer layer / aluminum foil / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene layer / polyester layer / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene Layer / polyester layer / polyethylene resin layer (film), polyethylene resin layer / paper layer / polyethylene layer / aluminum foil / biaxially stretched polyester layer / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene layer / deposited aluminum layer / polyester Layer / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene resin layer / silica vapor deposition layer / polyester layer / polyethylene resin layer (film), paper only, paper layer / polyethylene resin layer.

  The cylindrical upper end of the container body 1 is an opening of the container with a lid, and an inward top curl portion 3 is formed there. The inner peripheral surface of the inward top curl portion 3 is an upper inner surface 5 of the container main body 1 into which a convex portion 4 described later of the lid body 2 is fitted.

  The container body 1 is reinforced by the inward top curl portion 3. Moreover, since the top curl part 3 is provided inwardly, the protrusion from the outer peripheral surface of the container main body 1 reduces.

  The bottom of the container body 1 is closed with a bottom lid 6. The bottom lid 6 is also formed into a disk shape from the paper sheet, and is attached to the lower end of the container body 1 by winding or the like.

  The lid body 2 is formed into a disk shape by punching or the like from a paper sheet similar to the paper sheet constituting the container body 1. As described above, since the lid 2 is formed mainly of paper together with the container main body 1, the lidded container is excellent in recyclability and light-shielding properties, and is excellent in environmental performance even when discarded.

  When the lid 2 is punched from the paper sheet, the knob 7 is also formed integrally. The knob 7 is formed in a tongue shape, for example, and is attached to the side surface of the container body 1 with an adhesive or the like so as to be peeled off when the lid 2 is put on the container body 1. Since this knob 7 can be easily picked with a finger, the container with lid can be easily opened and can function as a pill fur proof.

  The lid 2 is formed with a convex portion 4 that can be repeatedly fitted into the upper inner surface 5 of the container body 1. The convex portion 4 is formed in a concave shape by squeezing the paper sheet by press molding, for example. A convex portion is formed on the lid body 2 by bonding the opening edge of the concave shape to the ceiling surface of the lid body 2 with an adhesive or the like. Although not shown, a flange portion may be formed at the opening edge of the convex portion 4 and the flange portion may be bonded to the ceiling surface of the lid 2.

  When the lid 2 is put on the container body 1 from above the opening, the outer peripheral surface of the convex portion 4 of the lid 2 is in close contact with the upper inner surface 5 of the container body 1 as shown in FIG. Thereby, the lid body 2 is fixed to the container body 1 with a large engagement force, and the closing force of the lid body 2 is increased. Further, the convex portion 4 of the lid body 2 can be repeatedly fitted into the upper inner surface 5 of the container body 1. Thereby, resealability is given to this container with a lid, and the preservability of the contents a stored in the container body 1 is improved. Moreover, since the convex part 4 of the lid 2 is adapted to be accommodated in the upper inner surface 5 of the container main body 1, there are fewer protrusions from the container main body 1 to the outside.

  In addition, it is desirable to previously form a water vapor adsorption layer on the paper sheet forming the convex portion 4 and the lid 2 by applying a paint containing a water vapor adsorbent by printing or the like. Thereby, the water vapor which permeate | transmits the cover 2 and the paper layer of the container main body 1 is adsorbed by the water vapor adsorption layer, and the contents a in the container main body 1 can be protected from moisture.

  As shown in FIGS. 1 and 2, the lid 2 is connected to the container body 1 by a hinge piece 8. The hinge piece 8 is formed on the paper sheet constituting the lid 2 so as to be bent. As shown in FIG. 3, when the lid 2 is opened, the hinge piece 8 bends, and even when the lid 2 is released as shown in FIG. 4, the open state of the lid 2 is maintained by paper folding. Therefore, the contents a can be easily taken out.

  More specifically, as shown in FIGS. 1 and 2, the hinge piece 8 is formed by being divided on a paper sheet constituting the lid body 2 via a broken line 8 a. The broken line 8a is formed at the same time when the lid 2 is punched from the paper sheet. The edge of the hinge piece 8 is joined to the top surface of the inwardly top curled portion 3 of the container body 1 by an adhesive. Thus, since the hinge piece 8 is formed using a part of the lid body 2, it is not necessary to separately provide a hinge, and an increase in the size of the lid body 2 is prevented.

  When the lid is opened, as shown in FIG. 3, the lid 2 is bent on the broken line 8a, and a crease is attached to the broken line 8a. Further, the portion of the convex portion 4 facing the hinge piece 8 is peeled off from the hinge piece 8 when the lid is opened. In addition, it is also possible not to adhere the convex part 4 to the location corresponding to the hinge piece 8. Even after the lid 2 is opened in this manner, the lid 2 is held by the container body 1 via the hinge piece 8 so as to be bent.

  As shown in FIG. 2, the inner side of the opening of the container body 1 closed by the lid 2 is sealed with an inner seal portion 9. The inner seal portion 9 is provided as necessary. By providing the inner seal portion 9, the initial sealing performance of the container body 1 is enhanced.

  As shown in FIG. 6, the inner seal portion 9 is formed in a disc shape so that the development plane thereof corresponds to the opening of the container body 1.

  As shown in FIG. 7A, the inner seal portion 9 is formed of a laminated body having at least two layers. The outer layer 9a has, for example, a laminated structure of barrier film / olefin resin layer, and the inner layer 9b has, for example, a laminated structure of olefin resin layer / paper layer / olefin resin layer, and welds the olefin resin layers together. Thus, the inner and outer two layers are overlapped.

  Moreover, as shown in FIG.6 and FIG.7 (A), the tearing part 10 is formed in the outer layer 9a by the cut lines 10a and 10b. The cut lines 10a and 10b are provided along two large and small circles, and an annular tearing portion 10 is formed between the two circles. In addition, a cut line 10 c that crosses the annular tearing portion 10 is also provided, and a knob portion 11 is formed in the annular tearing portion 10 by the cut line 10 c. These cut lines 10a, 10b, and 10c are preferably formed in a perforated shape, but can also be formed as continuous lines.

  6 and 7A, the inner seal portion 9 is heat-sealed to the inner peripheral surface of the container main body 1 by, for example, ultrasonic waves as a bonding allowance 9a as a bonding margin 9a.

  When the inner seal portion 9 is opened, the knob portion 11 is torn along the cut line 10c with a finger or the like, and then the knob portion 11 is pulled, so that the annular tear portion 10 becomes the inner portion as shown in FIG. It is excised from the seal portion 9. Thereby, the inner seal part 9 is opened.

  It should be noted that desired contents such as an olefin resin layer, a paper layer, and a film of a paper sheet used for the container body 1, the lid 2, and the inner seal portion 9 are externally printed by printing or the like as required. Is displayed in a visible manner.
