TECHNICAL FIELD OF THE INVENTION
The present invention relates to a clay package and a method of packing clay, and in particular, even when children touch the finger, the clay package does not easily lose its shape, and has excellent packaging properties and ease of use. The present invention relates to a method for packaging clay.
[0002]
[Prior art]
Conventional clay is composed of calcium carbonate as a main component and kneaded with pulp, water, a binder, an antifungal agent, etc., and is heavy and easily cracked when dried. A spot was seen. Therefore, in recent years, a lightweight clay comprising a synthetic binder, minute hollow spheres, pulp, water, and other additives has been proposed. Then, in consideration of storage and transportation of the lightweight clay, the lightweight clay is formed into a predetermined shape and then directly packaged with a plastic film.
However, in the case of a package in which lightweight clay is directly packaged, children may touch it many times when selling it in a store, or strongly grip and press from the side during transportation or storage. Therefore, there is a problem that the lightweight clay is easily deformed, and the commercial value is apt to be remarkably reduced. In addition, it is necessary to add a relatively large amount of water to such lightweight clay so that the clay can be easily formed. However, there is a problem that the clay is easily deformed and loses its shape.
[0003]
On the other hand, as a method of packaging a plurality of light-colored clays of different colors, a partitioning material is used, or a hard plastic container having an opening on one surface or a side surface in the longitudinal direction and a partitioning material is provided with a plurality of different colors. A method is disclosed in which after the lightweight clay is stored, the rigid plastic container or the like is hermetically packaged (pillow packaged) with a plastic film or a lid attached to the container (see Patent Documents 1 to 3).
However, such a partition material and a hard plastic container having the partition material are easily deformed because no treatment is applied to the side edges, and it is difficult to accurately package the packaging material with the packaging material. Problem was seen. In addition, in a package sealed and packaged with a lid provided with a container, there was a problem on the product that the lightweight clay could not be touched. Furthermore, after opening the plastic film, not only the rigid plastic container has no handle, but also the space between the partitioning material or the rigid plastic container and the packaging material is small, so the plastic container containing the lightweight clay There was also a problem in use that it was difficult to put in and out.

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment relating to a clay package and a clay packaging method of the present invention will be specifically described with reference to the drawings as appropriate.
[0015]
[First Embodiment]
The first embodiment is, as illustrated in FIG. 1, a clay package 10 that is covered with a packaging material 20 in a state in which a clay 12 is accommodated in a container 14, wherein the container 14 is a part of the clay 12. This is a clay package 10 having an opening 17 for exposing the opening, and having a wide edge 16 around the opening 17.
[0016]
1. Container (1) Overall Form The overall form of the container is not particularly limited as long as it can accommodate a predetermined amount of clay, expose a part of the clay, and can be externally touched via a packaging material. However, for example, as shown in FIG. 1, it is preferable that the opening 17 is a tray-shaped container 14 whose upper part is open.
The reason is that with such a tray-shaped container, clay can be stored or transported while holding a predetermined amount of moisture, and simply surrounded from outside by a packaging material. This is because packaging can be performed with high accuracy. In addition, in the case of such a tray-shaped container, the upper side is open, and has a function of an opening described later, so that even when children touch, the movement of the clay is restricted, This is because it is possible to easily maintain a predetermined shape without causing shape loss. Furthermore, with such a tray-shaped container, it is easy to put it in and out of the packaging material after opening, and even if there is residual clay, it can be stored again. .
[0017]
Further, the container is easy to be integrally molded by injection molding or the like, is inexpensive, has excellent transparency, and is non-adhesive to clay. Therefore, the container is made of polyethylene terephthalate resin (PET resin) or polypropylene resin (PP resin). ), A polyethylene resin (PE resin), a polyamide resin (PA resin), an acrylic resin (AA resin), or the like.
In addition, it is more preferable to use a polyethylene terephthalate resin because the thickness of the wall or the like in the container can be reduced to 0.5 mm or less, more preferably 0.4 mm or less and the heat resistance is excellent.
[0018]
(2) Opening In the first embodiment, as illustrated in FIG. 1, an opening 17 is provided in a part of a container 14 for accommodating the clay 12.
The reason for this is to expose a part of the clay through the opening so that the state of the clay can be touched from the outside via the packaging material. Therefore, children as consumers can feel the touch as clay, and can improve the commercial value.
[0019]
Here, the shape and number of the openings, the set position and the size, etc. are not particularly limited. For example, a circle, an ellipse, a square, other polygons, a line, a star or an animal It is preferable that at least one opening having a size that can be touched by children is provided above the container that accommodates the clay and has an irregular shape such as a shape.
However, as shown in FIG. 1 or FIG. 2, as a container 14 having an opening 17, as shown in FIG. 1 or FIG. It is more preferable to use a tray-shaped container whose upper part is entirely open.
[0020]
In addition, a transparent small window, for example, a transparent plastic film as a packaging material, and a non-printed portion may be provided on a part of the packaging material so that the color of the clay can be identified. It is preferable to provide an opening of the container so as to overlap the position of the small window.
The reason for this is that if such a transparent small window is provided, it is necessary to press the location in terms of human psychology. Therefore, if the opening of the container is provided in accordance with the location, the feel of the clay can be sufficiently touched. This is because we can do it.
In addition, if the display or the like indicating that the color and feel of clay can be identified through the transparent small window on the packaging material around the transparent small window, the transparent small window will be more reliably touched. .
[0021]
(3) Wide Edge In the first embodiment, as illustrated in FIG. 1, the wide edge 16 is partially or entirely provided along the periphery of the opening 17 in the container 14. It is characterized by.
The reason for this is that, with such a configuration, the strength of the container itself is improved with a simple configuration, a lightweight clay or the like containing a relatively large amount of water is contained, and the finger is touched many times. This also prevents the shape from being easily deformed.
In addition, since the container has such a wide edge, the contact area with the packaging material is reduced, so that the container can be easily inserted into the packaging material at the time of packaging, or the container can be easily taken in and out after opening the packaging. It is because it can be.
Furthermore, in the case of a tray container having an opening provided above, if a wide edge is provided around the opening, the slack of the packaging material on the side is reduced, and characters and graphics displayed on the side of the packaging material are reduced. This is because the recognition rate of such items increases, and the commercial value further increases.
[0022]
Here, as illustrated in FIG. 1, the wide edge portion 16 of the container 14 is preferably a bent portion in which the side wall of the container 14 extends.
The reason for this is that with this configuration, even with a simple container configuration, the strength of the container can be improved, and deformation of the container during packaging can be effectively prevented. In addition, if the side wall is a bent portion extending in this manner, a flat portion can be easily formed on the upper surface, and the plastic film is cut off by the edge of the opening during packaging, which is a manufacturing problem. Can be easily solved. Furthermore, with such a configuration, it is possible to accurately form the size by injection molding or the like while appropriately adjusting the size.
In addition, while the planar shape of the wide edge portion is linear or wavy, the width is preferably set to a value within a range of 0.1 to 10 mm, more preferably a value within a range of 1 to 6 mm. , 2 to 5 mm.
[0023]
(4) Bottom As shown in FIG. 2B, it is preferable that the bottom 18 of the container 14 be provided with an uneven portion 19.
The reason for this is that with such a configuration, even when clay containing a relatively large amount of water is contained in the container, or when a plurality of clays having different adhesive properties are contained, the clay is This is because sticking to the bottom of the container can be effectively prevented, and the container can be easily taken out.
In addition, with such a configuration, the contact area between the bottom of the container and the packaging material is effectively reduced, so that the container can be more easily taken in and out with the clay contained therein.
[0024]
Here, the uneven portion 19 shown in FIG. 2B is an example of an uneven portion having a circular planar shape, but may be an uneven portion having a polygonal planar shape or an uneven portion having a linear or wavy line shape. There may be.
In addition, in the example shown in FIG. 2B, an uneven portion 19 is provided on the entire bottom portion 18 of the container 14. However, in a case where the clay is to be peeled off from the bottom portion 18, the container 14 has It is also preferable to form the non-uniform portion only around the bottom portion 18.
Further, in the example shown in FIG. 2B, a part of the bottom part 18 of the container 14 is deformed to provide the uneven part 19, but the detachable uneven part is provided separately from the bottom part 18 of the container 14. Is also preferably provided.
[0025]
Further, as a modified example of the uneven portion on the bottom of the container, it is preferable that the container further includes an opening for exposing a part of the clay so that the clay can be pressed.
The reason is that even if a part of the clay is firmly attached to the bottom of the container, it can be easily removed by pressing the clay with a finger or a stick through the opening provided in the bottom. This is because
It is sufficient that there is at least one opening at the bottom, and it is preferable that the opening also serves as the above-mentioned uneven portion or is used in combination. Also, the shape and size of the opening at the bottom are not particularly limited, and for example, a circular opening having a diameter of 5 to 30 mm is preferable.
[0026]
(5) Cross-sectional Shape As illustrated in FIG. 2, it is preferable that the cross-sectional shape of the container 14 is substantially inverted trapezoidal, and that the frontage becomes wider toward the upper opening 17.
This is because a predetermined space is provided between the inner wall of the container and the packaging material, so that the clay can be more easily put in and out of the container. Therefore, it is preferable to provide a side wall inclined about 3 to 30 degrees with respect to the vertical direction.
[0027]
2. The type of the clay clay is not particularly limited, and examples thereof include lightweight clay, shirasu balloon clay, earth clay, and the like. In particular, lightweight clay is preferable. In this case, it is preferable that the lightweight clay is composed of a predetermined amount of a binder resin, expanded hollow microspheres, pulp, water, a binder and the like.
Further, the binder resin is composed of 0.1 to 30% by weight of a polyvinyl alcohol resin or the like as a binder resin, and the outer shell is formed of a vinylidene chloride-acrylonitrile copolymer resin or the like as hollow microspheres, based on the total amount of the lightweight clay. It is preferable to contain 0.1 to 6% by weight of a foam such as organic hollow microspheres containing gas or liquid, and 1 to 10% by weight of fiber or the like as pulp.
Further, the clay is preferably a lightweight clay having a water content of 60 to 85% by weight based on the total amount.
The reason is that a lightweight clay having such a water content can provide a lightweight clay excellent in touch and extensibility, and effectively prevent such lightweight clay from excessively sticking to the bottom and side walls of the container. This is because you can do it.
[0028]
3. Clay packaging body As illustrated in FIG. 2, the clay packaging body was housed in a container by a packaging material 20 on which predetermined characters, figures, symbols, etc. were printed, for example, a polypropylene film or a polyester film. Preferably, the clay is packaged and configured.
The reason for this is that the clay can be stored for a long period of time while maintaining the feel and the extensibility of the clay, and the clay can be effectively prevented from excessively sticking to the bottom and side walls of the container.
[0029]
[Second embodiment]
The second embodiment is a method of packaging clay for packaging with a packaging material in a state in which the clay is contained in a container, comprising an opening for exposing a part of the clay, and Using a container provided with a wide edge around the opening, a step of accommodating the clay in the container, and a step of packaging with the packaging material in a state where the clay is accommodated in the container, The packaging method.
