Description

  The present invention relates to a container having an open end at the bottom of a hollow hemisphere, and in particular, by forming the sphere by joining the hemispheres to each other at the open end, or closing the open end of the hemisphere. By this, it is related with the container which stores a toy etc. in internal space.

  Many coin-operated vending machines are installed in stores such as family restaurants and supermarkets to discharge spherical containers containing various toys by handle operation. Usually, this capsule type container is composed of two hollow hemispheres. The bottom surface of each hemisphere has an open end. The open end is fitted to each other to form a sphere, thereby forming a container for storing the toy. As described above, by forming a spherical body, the container can be smoothly discharged even if it is packed in the vending machine.

  The two hemispheres constituting the container are usually formed of synthetic resin materials having different hardnesses in order to facilitate fitting. This is made of a softer synthetic resin with a concave groove on the outer periphery of the open end of one hemisphere and a convex protrusion on the inner periphery of the open end of the other hemisphere. This is because the open end of the hemisphere is deformed in the diameter increasing direction, and is forcedly pushed in until the concave groove and the convex protrusion are fitted. Specifically, in general, a hemispherical material having a high hardness is a polystyrene (PS) resin, and a polypropylene (PP) resin is used for a hemispherical material having a low hardness.

By the way, the containers made of these materials are discarded without any particular use after the toy is taken out. Measures to reduce the load of have been desired. In addition, since an increase in the price of plastics as raw materials also affects the price of the final product, it has become an urgent issue to consider the production of containers from the viewpoint of cost.

  In order to solve the above problems, conventionally, a container is constituted by a biodegradable material to which a fertilizer component is added, which is used as a core member of a toy that houses the container body in the container (see Patent Document 1), Such a container has been proposed in which the stored item is used as a seed for growth and the container is used as a fertilizer for seed growth (see Patent Document 2).

  However, in the prior art, for example, in the case where the container itself is reused as in the device described in Patent Document 1, as described above, the shape of the container can be easily discharged from the vending machine. In order to store the toy in the first place, it must be formed in the first place, and there is a limitation in form that the inside must be hollow, so variations as a product are limited, There were doubts about the effect of actively promoting reuse.

Further, when the material can be biodegradable as in Patent Document 2, there is a problem of strength, and when storing seeds for growing inside, the types of stored toys are remarkably limited. There is a problem that it is difficult to meet the current diverse customer needs.

In addition, in the container with toys sold by the vending machine, the container is generally transparent so that the toy in the container can be seen, but from polystyrene (PS) resin and polypropylene (PP) resin. In the present container, the hemisphere made of polypropylene resin has to be colored due to the nature of the material, and it has been difficult to make the entire container into a colorless and transparent sphere at low cost.

In view of the above problems, an object of the present invention is to provide a container for storing a toy or the like that has good visibility from the outside and is low in cost and easy to discard.

  In order to achieve the above object, a container according to the present invention is a container for forming a hollow sphere by connecting two members having an open end to the bottom of a hollow hemisphere at the open end. Each of the two hemispheres is made of colorless and transparent polyethylene terephthalate, and the sphere is formed by covering the outer periphery of each open end with a shrink wrapping material made of polyethylene terephthalate film. It is characterized by being.

According to this configuration, it is possible to form a container made of the same transparent and colorless material with good visibility. Moreover, by making all the materials including the shrink wrapping material polyethylene terephthalate, it is possible to provide a low-cost container that is easy to recycle.

On the outer surfaces of the two hemispheres, radial ribs may be continuously formed at equal intervals in the circumferential direction so that a triangular shape with the apex direction as the apex and the opening end direction as the base is formed. Good. By forming the rib, the strength can be reinforced against the pressure applied from the outside of the container.

A flange having the same width in the radial direction is formed in a flange shape on the peripheral edge of the opening end of the two hemispheres, and the sphere is formed by covering the outer periphery of the shrink wrapping material with the hemisphere of each hemisphere overlapped. Also good. The formation of the collar part makes it easy to superimpose hemispheres, and when the collar part is overlaid, the collar part protruding outside is covered with a shrink wrapping material so that the entire outer surface forms a smooth curved surface. be able to.

The collar formed on the one hemisphere has a skirt formed by hanging from the periphery of the collar and the width of the collar of the hemisphere without the skirt by sliding the inner wall of the skirt. A hemispherical collar portion that does not have the skirt portion at the position where it is merged on the sliding track so as to be united with the collar portion having the skirt portion, so that it can be fitted. And a locking projection forming a groove-like shape formed integrally with the hemisphere, and the shrink wrapping material may cover the entire skirt portion in the fitted state. By forming the fitting portion with the locking projection, it is possible to force-fit using the flexibility of the material, and thus it is possible to reinforce the fitting strength. Note that two or more locking protrusions may be provided at equal intervals in the circumferential direction of the skirt portion.

A hinge portion may be provided on the periphery of the open ends of the two hemispheres so that the two hemispheres are integrally connected. According to this structure, even after taking out the toy etc. which were accommodated in the container, the hemisphere which comprises a container can be discarded integrally, without disperse | distributing everywhere.

The hinge portion may be formed with a fold line so that the hinge portion protrudes into the sphere when the sphere is formed by bending. According to this configuration, since the hinge portion can be prevented from protruding outside the container, the plurality of containers housed in the vending machine are formed into spheres with no irregularities on the entire surface, so that smooth discharge is possible. It becomes possible. In addition, a non-cut portion may be provided in a part of the collar portion of the two hemispheres, and the two hemispheres may be integrally formed using the non-cut portion as the hinge portion. According to this configuration, for example, when a container is injection-molded, a complicated mold becomes unnecessary.

Further, a container having a hollow hemisphere bottom surface as an open end, the hemisphere is made of a colorless and transparent polyethylene terephthalate, and at least a part of the outer peripheral surface is constituted by a circumferential polyhedral wall, The open end may be closed with a flexible polyethylene terephthalate film. According to this configuration, it is not necessary to form the hinge portion, and the toy can be stored in a hemisphere, so that both the material cost and the manufacturing cost can be reduced.

  As is clear from the above description, the container according to the present invention is uniform in the material of colorless and transparent polyethylene terephthalate, so that the visibility from the outside is better and the cost is lower than the same type of conventional containers. In addition, there is an effect that it is possible to provide a container for storing a toy or the like that can be easily discarded.

  The container according to the present invention is used, for example, as a container for individually storing the toy in a coin-type vending machine that discharges the toy by a handle operation. Usually, the vending machine has a case for storing the container, and one handle is discharged by one handle operation from a discharge port provided below the case by the handle operation. It is configured. Containers are discharged sequentially from the one closest to the discharge port due to the falling of its own weight, but the discharge port is provided with a space where only one container can be discharged. is there. Therefore, it is preferable that the shape of the container is basically a sphere with as few irregularities as possible, or a shape approximate to a sphere. Each embodiment will be described below. The following embodiments are not intended to limit the present invention. In addition, each constituent element shown in each embodiment can be replaced with a known constituent element, and can be developed into various variations by combining with other known constituent elements.

<Embodiment 1>
Referring to FIG. 1, reference numeral 1 denotes a container according to the present invention. The container 1 combines the two hemispheres 11a and 11b to form the sphere. The materials of the hemispheres 11a and 11b are both colorless and transparent polyethylene terephthalate. The hemispheres 11 a and 11 b are formed in a hollow shape so that the toy T can be stored in the container 1. The sphere is formed by overlapping the open ends 111a and 111b on the bottom surfaces of the hemispheres 11a and 11b so as to face each other. The outer periphery of the overlapped opening ends 111a and 111b is covered with a shrink wrapping material 12 made of a polyethylene terephthalate film.

By the way, in the present invention, the materials of the hemispheres 11a and 11b are both polyethylene terephthalate. In the conventional container, a concave groove is provided on the outer peripheral edge of the open end of one hemisphere, and a convex protrusion is provided on the inner peripheral edge of the open end of the other hemisphere, The hemisphere was composed of materials with different hardness. Therefore, disposal of the container is different from each other in terms of recycling, and it takes time and effort. In particular, many of the products according to the present invention are intended for children, and it is difficult for children to understand the separation of waste. In addition, children are interested in toys that are stored inside containers. However, since it is in a form that can be completely separated, there is a risk that either one will be dissipated and disposal in accordance with the Container Recycling Law will not be performed. In the present invention, the recycling material is unified with polyethylene terephthalate, which is highly recognized, to facilitate disposal. By using polyethylene terephthalate as the material, it is possible to reduce the weight of the container and to reduce the manufacturing cost.

In addition, in the conventional container, it may be difficult to make the entire container colorless and transparent due to, for example, a hemispherical material such as polypropylene resin. However, in the container according to the present invention, any hemisphere is made of polyethylene terephthalate. Therefore, the entire container can be made colorless and transparent. As a result, the visibility of the toy T is enhanced from the outside, and an effect of increasing the purchase motivation can be expected.

Hereinafter, in Embodiments 2 to 6, for the sake of explanation, description is made in a state where the toy T is not housed. However, since the material is colorless and transparent polyethylene terephthalate, If stored, it can be observed from the outside, including color.

<Embodiment 2>
Referring to FIG. 2, 2 is a container having reinforcing ribs formed on the outer surface. The toys stored in the containers sold by the vending machines are currently approximately 200 to 300 yen in unit price, so it is a reality to use high-cost materials to reinforce the containers. Not right. Therefore, in this embodiment, ribs are formed on the surface of the container 2 in order to reinforce the strength at a low cost. In the present embodiment, embossing is performed from the hollow inner side surface of the hemisphere 21a, and convex ribs are formed on the outer surface. The ribs are continuous at equal intervals in the circumferential direction of the opening end 211a so that a triangular shape is formed with the apex direction of the hemisphere 21a as the apex and the base of the opening end 211a direction. With such a configuration, the hemispherical body 21a has a truss structure with ribs formed on the outer periphery, and the strength is reinforced. In the present embodiment, not only a simple triangle continuation but also a triangle formed by ribs is formed into a so-called split truss structure to reinforce the strength in a multiple manner and consider design that does not impair the appearance of the appearance. The configuration. That is, a small circle 22 concentric with the opening end 211a is formed at the top of the hemisphere 12a. The small circle 22 has six starting points 22a, 22b, 22c, 22d, 22e, and 22f that are equally spaced in the circumferential direction. A triangular rib connecting the starting points 22a, 22c, and 22e and a triangular rib connecting 22b, 22d, and 22f are formed. That is, by forming triangular ribs that connect the starting points at intervals of 120 degrees, overall star-shaped ribs are formed in the small circle 22.

From the starting points 22a to 22f, a position 40 degrees away from the corresponding point of each starting point when the opening end 211a is divided into six equal in the circumferential direction corresponding to each starting point 22a to 22f. Ribs are formed as end points, and two ribs are formed from the same starting point, with the end points being 20 degrees apart from the end points of the ribs in the counterclockwise direction. That is, for one starting point, three ribs are formed at intervals of 20 degrees on the end point side, and the end point of the rib closest to the starting point is more than the corresponding point when the opening end 211a is divided into six equal parts. The position is 40 degrees counterclockwise. On the other hand, three ribs are formed at the position where the three ribs are inverted from the same starting point in the clockwise direction with the starting point and the corresponding point as axes. However, the rib formed in the clockwise direction is a rib between the intersection point of the rib formed in the counterclockwise direction from the starting point 120 degrees counterclockwise from the starting point of the rib and the starting point. Is not formed.

The structure of the rib will be described with reference to the starting point 22a in FIG. Three ribs 221a, 222a, and 223a are formed counterclockwise from the starting point 22a. The end point of the rib 221a is a point that is 40 degrees counterclockwise from the corresponding point 2111a of the starting point 22a of the opening end 211a, and the end points of the rib 222a and the rib 223a are points that are sequentially 20 degrees counterclockwise thereafter. It has become. On the other hand, three ribs 224a, 225a, and 226a are also formed clockwise from the starting point 22a, but ribs 221e that are formed counterclockwise from the starting point 22e that is 120 degrees counterclockwise from the starting point 22a, Ribs are not formed between the intersections with 222e and 223e and the starting point 22a.

  With the configuration described above, the open end 211a can be divided into 20 degree increments to form 18 triangles with the arc as the base on the outer surface of the hemisphere 21a, and two adjacent triangles can be included. Nine larger triangles are formed. In this case, the adjacent sides of the encapsulated triangle serve as a case truss that reinforces the large triangle, and the strength can be reinforced in multiple ways.

The six ribs formed from the starting points may be reversed in the clockwise direction and the counterclockwise direction. In the following, the third to fifth embodiments are not provided with ribs for convenience of explanation, but may be provided with the ribs.

<Embodiment 3>
With reference to FIG. 3, 3 is a container provided with a flange-shaped flange. In addition, both this embodiment and Embodiment 5 mentioned later are modifications of what provided the collar part. In addition to the present embodiment and Embodiment 5, two hemispheres may be provided with flanges, and the outer periphery of each flange overlapped with each other may be covered with the shrink wrapping material (not shown). .

The container 3 combines the hemisphere 31a and the hemisphere 31b to form a sphere. The hemisphere 31a is provided with a flange portion 311a having the same width in the radial direction on the periphery of the opening end of the bottom surface, and hangs from the periphery of the flange portion 311a to form a skirt portion 312a. The skirt portion 312a is formed by embossing a rectangular locking projection 313a from the outer periphery of the skirt portion 312a toward the center of the opening end. The outer periphery of the skirt portion 312a when the hemisphere 31a and the hemisphere 31b are combined is covered with the shrink wrapping material 32 including a part of the outer surfaces of the hemispheres 31a and 31b.

FIG. 4 shows an enlarged side sectional view of the locking protrusion 313a in a state where the hemisphere 31a and the hemisphere 31b are combined. Between the locking projection 313a of the hemisphere 31a and the flange 311a, the groove 311b of the hemisphere 31b can be fitted at a position where it is combined with the flange 311a of the hemisphere 31a. 314a is formed. The collar portion 311a of the hemispherical body 31b has a size capable of sliding on the inner wall of the skirt portion 312a. The locking projection 313a is formed on the track of the sliding inner wall. Since the locking protrusion 313a is formed of polyethylene terephthalate, it has flexibility. Therefore, if the flange 311b of the hemisphere 31b is slid and inserted from the skirt of the skirt 312a and is pressed into the groove 314a by forcibly fitting when it is in contact with the locking projection 312a, the hemisphere 31a and the hemisphere 31b Can be united reliably. FIG. 5 is a bottom view seen from the open end side of the hemisphere 31a. In the present embodiment, ten locking protrusions 313a are provided at equal intervals in the circumferential direction of the opening end, but the present invention is not limited to this. However, it is preferable to provide two or more at equal intervals at least in the circumferential direction in order to reliably combine them.

<Embodiment 4>
6, 7, and 8, reference numeral 4 denotes a container in which two hemispheres are provided with hinge portions and both hemispheres are integrally connected. The container 4 expands into the hollow hemispheres 41a and 41b in order to take out the toy. However, as shown in the development view of FIG. 7, the container 4 is moved by the hinge portion 42 even when expanded into the hemispheres 41a and 41b. Since they are integrally connected, the hemispheres 41a and 41b do not dissipate. The hinge part 42 is joined to a part of the periphery of each opening end. As shown in the side sectional view of FIG. 8, the hinge part 42 is formed so that the folding line forms a mountain fold toward the inside of the sphere when the sphere is formed, so that the hinge part 42 protrudes inside and the outside of the sphere It is not exposed on the surface. By preventing the hinge portion 42 from being exposed to the outer surface, the entire container 4 is configured as a sphere having a smooth outer surface so that the containers are not caught when discharged by the vending machine.

When both open ends are joined, the hemispheres 41a and 41b open in the unfolding direction due to the rebound resilience of the hinge portion 42. After joining both open ends, the outer periphery of the joined open ends is made of polyethylene terephthalate. What is necessary is just to coat | cover with the shrink wrapping material 43 which consists of a film.

<Embodiment 5>
A container 5 according to Example 5 will be described with reference to FIGS. 9, 10, and 11. In the present embodiment, flange-shaped flange portions 511a and 511b having the same width in the radial direction of the bottom surface are provided on the entire periphery of the bottom surface of the hemispheres 51a and 51b. The flange portions 511a and 511b are coupled to each other to form a spherical container 5.

  The container 5 to which the flange portions 511a and 511b are coupled to each other is coated with the outer surface including the entire outer periphery of the flange portions 511a and 511b with a shrink wrapping material 52 made of a polyethylene terephthalate film, thereby forming a sphere as a container. The

As shown in FIG. 10, the hemisphere 51 a and the hemisphere 51 b are integrally formed by the hinge portion 53. The hinge portion 53 is formed by providing a non-cut portion in a part of the flange portions 511a and 511b. With such a configuration, the container 5 according to the present embodiment does not have a perfect sphere on the outer surface, but with a uniform width over the entire outer periphery of the sphere with the flanges 511a and 511b facing each other. Therefore, it is possible to discharge without being caught from the vending machine. In particular, when the hemispherical body 51a and the hemispherical body 51b are joined together, the hinge part 53 has an outer shape that is absorbed by the collar part 511a and the collar part 511b, so that only the hinge part 53 protrudes. The shape of the outer surface is smooth, unlike the case where the hinge is simply provided in that it can be avoided.

Furthermore, in the manufacture of the container 5, for example, when the hemisphere 51a and the hemisphere 51b are injection-molded with a mold, the hinge portion 53 is naturally formed unless the portion where the flange portion 511a and the flange portion 511b contact is cut. Therefore, the manufacturing process is simple and the effect of reducing the manufacturing cost can be expected. In addition, since both the collar parts 511a and 511b are circular, in order to ensure the circular shape of the collar part at the time of the coupling | bonding, it must be a point contact, However, In this, the coupling | bonding force of the hinge part 53 is weak. is there. Therefore, it is necessary to make line contact to such an extent that the hinge function is achieved. However, since the diameter of the sphere is about 48 mm to 77 mm, the size of the container 5 is approximately 48 mm to 77 mm. Therefore, if the line contact portion forming the hinge portion 53 is a very small part of the entire circumference of the sphere, the flange portion 511a, When 511b is joined, the unevenness | corrugation which impairs the circular shape of the periphery of the joined collar part does not arise. Therefore, if it is the line contact of the above-mentioned level, there will be no problems such as catching when discharging from the vending machine.

<Embodiment 6>
The container 6 concerning Embodiment 6 is demonstrated using FIG. The container 6 is composed of a hollow hemisphere 61 made of polyethylene terephthalate. The hemispherical body 61 is the same as that constituting the container of each embodiment in that the bottom surface is the open end, but the container is composed only of the hemispherical body 61, and in the first to fifth embodiments. Different from previous containers. A lid 62 made of a polyethylene terephthalate film having the same shape as the bottom surface is attached to the periphery of the opening end of the hemispherical body 61 to close the opening end to form the container 6.

The lid 62 has flexibility, and the toy accommodated therein can be taken out by peeling the lid 62. In the present embodiment, the tongue piece 621 is provided on the radially outer side of the lid body 62 so that the lid body 62 can be easily peeled off. When the tongue piece 621 is affixed to the opening end, the tongue piece 621 may be bent in the side surface direction of the hemisphere 61 and brought into contact with the side surface. At the time of peeling, the lid 32 can be peeled off by pinching the tongue piece 621 and pulling it in the direction away from the opening end.

By the way, as described above, the container 6 includes only the hemispherical body 61 whose bottom surface is the open end and the flexible lid body 62 that closes the open end, and thus the first to fifth embodiments. Compared to previous containers, the strength against external pressure is weak. Increasing the thickness of the hemisphere 61 in order to increase the strength affects the manufacturing cost, transportation cost, and the like. Therefore, it is necessary to increase a certain strength against the external pressure even if it is thin.

In the present embodiment, a circumferential polyhedral wall 611 is formed on the outer circumferential surface of the hemisphere 61. The polyhedral wall 611 is a unit panel in which two triangles are joined at the bottom, and is arranged all around the side surface of the hemisphere 61. The phase in the depth direction of the hemisphere 61 of each adjacent unit panel is: They are shifted by half (one triangle) and closely arranged in the circumferential direction. With such a configuration, the strength can be increased.
