Description

High strength thin plate vessel

The present invention relates to a container that can hold various contents, and more particularly, by forming a polycylindrical or cylindrical reinforcement border integrally at the edge of the side wall to maintain the rigid rigidity without fluttering during use. The present invention relates to a highly rigid thin container that can be used stably and conveniently when containing contents.

With the development of the times, each individual's behavioral radius has widened, and convenient ritual household goods have been developed and distributed in various ways. Among them, the culture of eating and eating easily is rapidly changed. In particular, as the time to live outside the house increases, more people use lunches to buy or eat easily.

A disposable food storage container such as a lunch box is a container used to move food to another place, and is made of thin silver foil or synthetic resin material to be discarded after one use without reuse.

For example, for busy modern people, a simple lunch box is prepared at a restaurant or at home for each meal. Sometimes, disposable containers are used to carry rice, gimbap, and side dishes to the outdoors or office. As a container for simply containing food, a simple silver foil container, or a styrofoam container and a plastic container container have been mainly used. However, the existing silver foil containers or styrofoam containers were weak due to their weak strength, which made them uncomfortable to hold food and uncomfortable to hold even after the food was contained, and even the container itself was often damaged even before use. . In addition, these containers of silver foil or synthetic resin are not recyclable to encourage waste of resources, and once used, due to their disposable nature, they are disposed of. These discarded containers do not rot even after years of landfilling, causing environmental pollution. there was. In particular, disposable plastic containers not only cause serious social problems, but also have serious problems that threaten human health due to environmental hormones detected in the containers of dioxin and synthetic resins generated when these containers are disposed of.

As such, in the era of mass production and mass consumption, the vast amount of industrial waste is accumulated after the continuous pursuit of convenient and comfortable life. The environment of our living place, such as water and water resources, is being polluted as a whole. The earth on which we now live is an eternal human community where we as well as our descendants must live, so we all must not only revive the sick environment, but also strive to be no more polluted. Recycling is difficult or impossible because of the various kinds of household packaging and containers that are spilled around us, which not only pollutes the environment but also contains many substances or toxins that can directly threaten our health or life. Can be. Among the containers for storing foods, foods, and other agricultural products such as fruits and vegetables, the amount is very serious, and various synthetic resins and chemicals are overflowing. It's a very serious task that needs to be solved together.

Laminated containers of chemical synthetic resin systems, such as polyester (PET) and polypropylene (PP), which are widely used today for food and beverage containers, are easy and advantageous in terms of production, distribution and use, but as already pointed out above. Together with the expanded styrene resin, they will destroy the global environment due to various toxic and harmful substances. Therefore, they should be refrained from being used as container materials. In this context, there is an urgent need to replace environmentally friendly materials as a way to reduce environmental pollution or damage. Therefore, the material of the container is recyclable, and not only can be easily rotted when landfilled as garbage, but it must not destroy the soil, and when incinerated, it must not release toxic gases that harm health and make it sick. Various harmful substances such as formaldehyde should not be emitted.

For this reason, people think of materials that will not harm the environment or the human body. One of them is paper. Paper is the most widely used vegetable material in all fields in our field, and has all the above advantages. However, since the raw material itself is a natural fiber, its strength is not only weakly weak, but its shape is also a flat plate, which is difficult to manufacture and use containers. As such, the emergence of paper containers is urgently needed from the standpoint of reducing environmental pollution, but it is never easy to make containers from naturally weak paper, and the practicality of them is inevitably deteriorated.

As shown in FIGS. 1A and 1B showing simple and basic paper containers, there is no support or support for the side walls of the container (sides 110 and 110a), so the end of the side wall is too weak to bear the external pressure or the weight of the contents. When used with the actual contents, there was no practicality because it lost its function and form as a container such as its shape and twisting because it was very sulky and uncentered. The larger the container 100, the worse this phenomenon, and even if a thick container is used, such a shape may be less, but is not fundamentally solved. This phenomenon is the same in the case of thin sheet materials other than paper.

In summary, polystyrene foamed products among the containers distributed by the prior art have been pointed out that harmful substances are eluted, which impedes the public health as well as environmental protection. Paper products made of non-resilient, weak strength, unstable, thick paper to make a large container, because the price of the container increases, the weight increases, it is inconvenient to use, and adds to the consumer burden, so people avoid the use of great practicality There was no.

Accordingly, an object of the present invention is to solve the above-mentioned drawbacks, and to maintain the rigidity by integrally extending the polygonal or cylindrical reinforcement border at the edge of the side wall to maintain rigidity It is to provide a high rigidity thin container that doubles the rigidity by preventing the container from twisting or slack, and promotes stability, convenience and practicality.

High-strength thin container according to the present invention for achieving the above object is characterized in that it comprises a bottom plate and a cylindrical reinforcement border extending from the edge of the side wall in a container consisting of side walls extending from the bottom plate It is done.

The reinforcing edge is characterized in that the polygonal cylinder shape or cylindrical shape. The sidewalls are inclined to have a larger area toward the upper side, and in particular, an edge portion to which the sidewalls are connected is curved in a conical shape. The container may be coated with a polyethylene resin whose surface is waterproof and moisture resistant.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to a preferred embodiment of the present invention.

Figure 2 is a perspective view showing an embodiment of a high rigidity thin plate container according to the present invention, Figure 3 is an exploded view of a container having an angled corner shown in FIG. 4 is a sectional view taken along the line A-A of FIG.

The container 1 is composed of a bottom plate 10 having a predetermined size and sidewalls 20 extending upward from the bottom plate 10 to form a receiving space therein. At the edges of the side walls 20, a cylindrical edge 30 is integrally formed. In this embodiment, a triangular cylindrical reinforcement border 30 is illustrated, and the reinforcement border 30 extends around a corner to form one closed section. As such, the edges of the side walls 20 form a normal rim, thereby reinforcing the side surface of the container 1, thereby greatly increasing the strength. Therefore, the container 1 can solve the problem of grasping the side walls 20 and the problem that the side wall 20 drifts or weakens when the contents, for example food, are contained in the container 1. That is, since the reinforcing edge 30 formed at the ends of the side walls 20 forms a tubular structure, the container 1 is very firmly fixed because it does not bend inward or outward when holding the side walls 20 to hold or transport food. It is supported. In particular, as in the present embodiment, the triangular cylindrical reinforcing edge 30 is folded in the outer side by folding the first folding portion 32 from the side walls 20 in the development view of FIG. 4, and the first folding portion 32. After bending the second folded portion 34 extending outwardly from), the third folded portion 36 extending outwardly of the second folded portion 34 is bent therefrom and folded in a triangular barrel shape, and then The inside of the three-folded part 36 is in close contact with and adhered to the outer surface of the side wall 20 corresponding thereto to form a triangular cylindrical reinforcement border 30. In this case, the bonding method may be bonded by applying an adhesive to the corresponding surface of the side wall 20 and the third folding portion 36, and when the polyethylene resin is coated, bonding is possible by thermal fusion or ultrasonic fusion. Ultrasonic welding allows a clean finish after the container is finished. The tubular structure of the reinforcement rim 30 enables a very strong and robust structure structurally even using a thin plate material. This container 1 is produced by forming a folding line and folding it as shown in FIG. 3 using paper as a material.

In particular, as shown in Fig. 4, the container 1 is formed such that its sidewalls 20 are inclined so that the area thereof becomes larger. Because of this, it is convenient to put the contents in the container 1 and take out, it is also possible to contain a larger amount of contents, and further easy to stack several containers. The angle of inclination of the side walls 20 as described above is determined to meet the intended use of the container 1, the depth of the container 1 may be appropriately designed according to the size or capacity of the contents contained.

The container 1 may be used as it is without paper coating. On the other hand, at least one surface of the paper may be coated with a polyethylene resin to impart moisture and water resistance. For example, if you want to use the container for the purpose of storing dry goods, you can use the one without coating, and if you want to use it for the purpose of storing wet goods, you can use the one given the waterproofing by resin coating.

5A and 5B are cross-sectional views of a container showing other embodiments of the reinforcing edge shown in FIG. 4, wherein the reinforcing edge is formed in a triangular shape as described above, in addition to the rectangular cylindrical edge 30a illustrated in FIG. 5A. It can be configured as, and can further form a reinforcement border (30b) in a cylindrical shape as shown in FIG. In addition, hexagonal, octagonal or other polygonal shapes are possible. Of course, even if the reinforcing frame of the container in this various cylindrical shape, there is no difference in reinforcement of the container to be obtained in the present invention.

6 is a perspective view showing another embodiment of a high rigidity thin container according to the present invention, Figure 7 is a development of the container having a curved edge shown in FIG.

In this embodiment, by processing the corners of the angled corner container illustrated as a conical curved surface, the corners are rounded and wide so that unnecessary spaces do not occur in the corners when the contents are contained, so that the storage space is useful, and the corners are not rounded and uneven. Respond to contact and pressure more safely and firmly. As such, the curved edge container further enhances the safety, robustness, and practicality of the container and provides a visually more elegant, soft and comfortable feel. Conical curved edge containers are the same as angled edge containers in that they form a cylindrical reinforcement border on the sidewall edges, except that the corners form a conical curved surface.

Because of these differences, curved edge containers are more practical than angled edge containers. For example, most of the round fruits such as cherry tomatoes and tangerines are processed with rounded corners, so that unnecessary space is not left behind and gives a more beautiful visual appearance. Furthermore, since the edge portion 22 extends to the curved surface, the reinforcing edge 30c is formed, so that the force received on one side of the reinforcing edge is distributed to the neighboring reinforcing edges on the curved edge, so that it can withstand greater pressure (force). It becomes the container 1a.

The present container 1a having such curved edges is integrated with the edges of the sidewalls 20a and the edge portion 22a in a state where the sidewalls 20a are first folded from the bottom plate 10a in a developed view designed as shown in FIG. 7. While bending the first folded portion 32c of the reinforcing edge 30c extending to the outside, the first folded portion extending from the corner portion 22a is folded and deformed into a conical curved surface, and then the bottom plate 10a. If the corners 22a are overlapped with a conical surface with each vertex of the vertex as a vertex, the curved first folded portion of the extended corner portion also overlaps, forming a curved surface, and when the overlapping portions are joined, the edge of the container is conical curved surface. Will be achieved. Then, the second folded portion 34c and the third folded portion 36c extending outwardly of the first folded portion 32c that are already bent are folded in order to form a triangular cylindrical reinforcing edge 30c.

To reinforce the above contents, when the plane meets the plane at the edge, it is inevitably an angled corner, so in order to be a curved edge, the edge 22a of the side wall must be changed to the surface so that the side wall and the side wall do not meet the plane. do. At this time, the first folded portion 32c extending at the curved edge of the corner portion should be bent outwardly. In the curved state, the edge of the side wall (plane) and the edge (curved) is first because the first folded portion is not folded outward. While folding the first folded portion 32c, which is integrally extended to the outside, at the same time, the corner portion should be curved. In this way, the first folded portion can be bent outward and at the same time the edge can be changed into a curved state. Then, in a state where the side wall 20 is folded and inclined at a predetermined angle from the bottom plate 10a, the curved surface and the curved surface of the corner are overlapped and bonded, and the second folded portion 34c and the third folded portion 36c are sequentially By folding, a triangular tubular reinforcing edge 30c is formed, and is adhered to the outer surface of the side wall 20a to be completed.

Of course, the container 1a having such curved edges can be manufactured in the shape of a triangle, a pentagon, a hexagon, and other polygons in addition to the rectangular container, and the reinforcing edge 30c is also in addition to the triangular cylindrical shape illustrated in this embodiment. Square cylinder, hexagonal cylinder and other polygonal cylinder or cylinder can be implemented.

Figure 8 is a perspective view showing another embodiment of a high rigidity thin container according to the present invention, the container (1b) is manufactured in the hexagonal box form as illustrated in the figure in addition to the container of the rectangular box form described in the previous embodiment This is possible. Of course, at this time, six side walls 20b extending from the bottom plate 10b are configured, and six reinforcing edges 30d extending from the ends of the side walls 20b are also required. Therefore, the reinforcing edge 30d is formed to extend in a triangular cylindrical shape at the edge of the hexagonal cylindrical main container 1b.

Figure 9 is a cross-sectional view showing another embodiment of a high rigidity thin plate container according to the present invention, the previous embodiments are to increase the cross-sectional area toward the upper side, as in this embodiment, the container (1c) is bottomed side wall (20c) It can also be configured to be perpendicular to the plate 10c so that the top and bottom are the same cross section.

The embodiments disclosed herein are only presented by selecting the most preferred examples to help those skilled in the art from the various possible examples, the technical spirit of the present invention is not necessarily limited or limited only by this embodiment, the present invention Various changes and modifications are possible within the scope without departing from the spirit of the invention, as well as other equivalent embodiments.

As described above, the present invention not only solves the weakness of the paper material that is bent, twisted and squeezed out by the powerful force of the tubular shape by extending the tubular or cylindrical reinforcement border integrally to the edge, You will get a strong and strong container that is completely safe to use. Furthermore, by processing the corners of the container in a conical round curved surface to form a more comfortable and convenient storage space in practical use, there is an advantage that visually beautiful and soft to feel comfortable.

In this way, the present invention reinforces the cylindrical edge exerting a strong force on the upper end of the thin plate container, and the edge is rounded to a conical curved surface to provide both rigidity and usefulness at the same time. In the following, it will have a firmness and shape that is not comparable. Therefore, according to the present invention, even a thin plate of about 0.2 to 0.4 mm, which has not been spotlighted as a container material, it is possible to manufacture a strong and strong container that is perfectly suitable for practical use. Moreover, regardless of the size of the container, it can be made freely according to the use from small to large, and the strength of the container can also be freely adjusted according to the size of the container to maintain the strength that suits its size. have. Since the container of the present invention is very light in weight compared to other containers, the amount of raw materials required for the production of the container is small, so it is very economical in terms of resource saving and material cost. As a result, the number of consumer terminals can be reduced.

The present invention is also made of paper, so when you eat food, such as environmental hormones are not released, can contribute to the health of users and contribute to the protection of nature.
