Description

CONTAINER FOR MINIMIZING DEFORMATION AND MANUFACTURING METHOD THEREOF}

The present invention relates to a container, and more particularly, to a container for minimizing deformation due to heat and a method of manufacturing the same.

In general, a container for storing food or using as a washing and bowl is made of a synthetic resin material or a metal material to block the deterioration and contamination of food, and is formed to be stored for a long time.

These containers are easy to transmit temperature, so if you store hot foods or cold foods, you use trays or moving trays to move them from the cooked kitchen to the location of the user. Frequently, you have to move it yourself.

At this time, when the temperature of the contents is high, the temperature of the container is changed by the temperature of the food, it is difficult to move the container easily and there is an inconvenient drawback.

Moreover, the container made of metal has a disadvantage in that it is difficult to move and inconvenient to use because of its heavy weight.

In recent years, due to the high development of synthetic resin materials, it is frequently used to store or eat various foods, indoors and outdoors.

However, in the case of the synthetic resin material, the heat transfer coefficient is low compared to the metal container, but the heat transfer is not made rapidly, but it is easily deformed by an external magnetic pole or an external temperature change.

Thus, in recent years, in order to prevent the temperature of the contents from being transferred to an external container, the container is formed in a double shape to be conveniently used by a user.

The double formed container has a disadvantage in that a deformation of the container occurs due to an external stimulus or temperature change, so that a gap is generated between the outer container and the inner container and separated.

Looking at the background technology to compensate for this problem, in the "double container and its manufacturing method" of the Republic of Korea Patent Publication No. 10-1101876 (hereinafter referred to as 'Document 1'), inside the outer container containing a spaced guide projection on the inside Disclosed is a container that is formed such that the inner container is coupled to block the temperature of the contents from being transferred to the outer container.

When using the invention of the document 1, there is an advantage that can prevent the temperature of the contents contained in the inner container is transferred to the outer container by the spaced guide projection included in the outer container.

However, as shown in Fig. 1, the inner container is formed integrally by combining with the protruding jaw of the outer container, and the outer container and the inner container are integrally formed by welding using frictional heat, thereby combining the outer container with the inner container. In addition to this cumbersome, by applying a high temperature frictional heat to the protrusion of the outer container in order to maintain a strong bond, there is a disadvantage that the protrusion may be deformed and the combination of the inner container and the outer container can not be performed to cause defects. .

Looking at another background, in the "cooling cup" of the Republic of Korea Utility Model Publication No. 20-0366346 (hereinafter referred to as 'Document 2'), by forming a cooling fin and cooling projections in the inner cup by the refrigerant contained in the sealed space Disclosed is a cooling cup which increases the cooling effect of a beverage so that beverages such as beer contained in the cooling cup can be cooled in a short time and kept cool.

When using the invention of Document 2, the inner cup outer periphery by the cooling fins in contact with the outer cup inner periphery and the cooling projection formed in the inner cup center to provide a refreshing feeling to the drinker in a short time when drinking the drink, There is an advantage that can maintain the freshness of the drink for a long time.

However, as shown in Figure 2, when the refrigerant is injected into the sealed space formed between the inner cup and the outer cup to evaporate, there is a hassle to inject the refrigerant into the screw holes from time to time, The inner cup is coupled by the coupling jaw has a disadvantage that the outer cup and the inner cup can be easily separated by the external magnetic pole.

Looking at the other background, in the "plastic double insulation container" of the Republic of Korea Utility Model Publication No. 20-0473714 (hereinafter referred to as 'Document 3'), the internal and external containers overlap by vacuum molding the synthetic resin It is made to be made, and the insulating surface between the outer surface of the inner container and the inner surface of the outer container is insulated from each other and in close contact is repeated for a plurality of air pockets are formed.

When using the invention of the document 3, it is possible to minimize the change of food according to the outside temperature by increasing the heat insulation and insulation by the air pocket has the advantage that can be maintained in the optimum state of cooked food for a long time.

However, as shown in Figure 3, the inner container and the outer container is formed of a synthetic resin can be easily transformed by the external temperature, by being coupled by the combination of the inner container and the edge formed on the outer container, by the external magnetic pole There is a disadvantage that can be easily separated.

Looking at the other background, in the "cooking vessel with overheat prevention function" of the Republic of Korea Patent Publication No. 10-2006-0124369 (hereinafter 'Document 4'), a heat transfer member is formed between the outer wall and the bottom surface of the inner wall. When the inner temperature and the outer wall is contacted below a predetermined temperature to achieve heat transfer by conduction, and above a certain temperature, the inner and outer walls are spaced apart to disclose a cooking vessel capable of blocking heat transfer by conduction.

When using the invention of Document 4, as shown in Figure 4, the container is heated for a long time, the inner wall of the cooking vessel has the advantage that it can maintain a constant temperature, but the expansion or contraction by heat is repeated, the deformation caused by frequent use There is a disadvantage that the outer wall and the inner wall can be easily separated.

5 to 9, a container for minimizing deformation due to heat according to the present invention may be formed including a first container 100 and a second container 200.

The container for minimizing deformation by heat of the present invention will be described as a container for convenience of description.

In more detail, the first container 100 may be formed to include a space that can accommodate the contents inside.

In this case, the upper side of the first container 100 may be formed in an open shape, and may be formed of any one selected from a metal material or a synthetic resin so that the contents may be received and stored inward from the upper side of the first container 100.

Preferably, the first container 100 may be formed of a metal material in order to minimize the temperature change rate of the contents contained therein by the external environment, and most preferably, may be formed of a metal material of stainless steel having excellent corrosion resistance. have.

At this time, since the first container 100 is formed of a metal material, not only the expansion and contraction due to the temperature change is lower than that of the synthetic resin, but also the thermal conductivity is lower than that of the other metals, thereby maintaining the temperature of the contents for a long time.

In this case, the first container 100 may be formed by any one method selected from drawing processing or injection molding, depending on the material.

If the material of the first container 100 is a metal, a drawing processing method may be applied in which a metal formed in a plate shape is placed in at least one mold and pressed by a pressure press to be formed into a predetermined shape.

In addition, when the material of the first container 100 is a synthetic resin material, an injection molding method of injecting and molding the synthetic resin material into one or more molds may be applied to facilitate molding of the material, but is not limited thereto.

In addition, the first container 100 may be formed to include the first protrusion 121 and the first end 130.

First, the first protrusion 121 may be formed to protrude outward on one side of the first container 100.

In addition, the first container 100 is formed so as to guide the user so that the contents are accommodated in a proper capacity, and when combined with a cover including a lid, the contents can be prevented from overflowing by the received capacity. There is an advantage.

Next, the first end 130 may protrude outward from the upper end of the first container 100.

When the cross section of the first end 130 is formed in an annular shape and the contents overflow from the inside of the first container 100, the contents may be prevented from flowing between the first container 100 and the second container 200. Can be formed.

At this time, by providing enough space for the second end 230 to be drawn inside the first end 130, the first container 100 and the second container 200 may be formed so as not to be separated by heat change. Can be.

Optionally, an end of the first end 130 may be formed to be introduced into the second end 230.

By forming in this way, the first container 100 is prevented from being deformed by the external stimulus such as washing, so that the first container 100 and the second container 200 are more firmly coupled. There is an advantage that can be maintained.

As another embodiment of the first end 130, one or more rings may be further included inside the first end 130.

By further including one or more rings inside the first end 130, the first container 100 and the second container 200 are not only more firmly coupled, but also moisture or water inside the first end 130. There is an advantage that the penetration is prevented to improve the durability of the final container.

In this case, the ring included inside the first end 130 has a Shore hardness of 30 to 80, and a silicone rubber having a commercial temperature of -75 to 200 ° C may be applied, but is not limited thereto.

If the Shore hardness is less than 30 is applied, there is a disadvantage that can easily be broken in the process of combining the first vessel 100 and the second vessel 200 by a low hardness, if the Shore hardness is 80 or more, There is a disadvantage that the manufacturing cost for maintaining the hardness increases.

In addition, when the commercial temperature is less than -75 ℃, or more than 200 ℃ is applied, there is a disadvantage that the manufacturing cost for manufacturing a silicone rubber having a wide range of commercial temperature increases.

Next, the second vessel 200 may be formed to surround the outer surface of the first vessel (100).

The second container 200 is formed to surround the outer surface of the first container 100, thereby minimizing the temperature change of the contents contained inside the first container 100, as well as the first change by the temperature of the contents The temperature of the container 100 may be formed so that it is not transmitted to the user.

That is, even if a high temperature content is contained inside the first container 100, the user can easily move the final container by holding the second container 200 by the heat insulating property of the second container 200.

To this end, the second container 200 may be formed of a metal or a synthetic resin material, preferably, may be formed of a synthetic resin material having a significantly lower thermal conductivity than the metal.

Most preferably, ABS (Acrylonitrile Butadiene Styrene Copolymer) resin material having low thermal deformation and shrinkage may be applied, but is not limited thereto.

In this case, the second container 200 may be formed by any one method selected from drawing processing or injection molding, depending on the material.

If the material of the second container 200 is a metal, a drawing processing method may be applied in which a metal formed in a plate shape is placed in at least one mold and pressed by a pressure press to be formed into a predetermined shape.

In addition, when the material of the second container 200 is a synthetic resin material, an injection molding method of injecting and molding the synthetic resin material into one or more molds may be applied to facilitate molding of the material, but is not limited thereto.

In addition, the second container 200 may include a lower surface 210, a second side surface 220, and a second end 230.

First, the lower surface 210 is formed on the lower side of the second container 200, and one side is raised to form a second space portion 211 on the lower outer side.

That is, the lower side of the second vessel 200 is raised to form the second space portion 211, and the space is formed by the size of the second space portion 211 between the ground and one side of the bottom surface 210 of the container to be finally manufactured. By being formed, there is an advantage that can minimize the change in the temperature of the contents by the temperature difference between the ground and the contents.

Optionally, the lower side of the first container 100 may be formed in a flat shape, and the depth of the first container 100 may be formed as deep as the height of the second space portion 211 of the second container 200. have.

At this time, the vacuum pad is connected to any one selected from the projections or grooves and the vacuum pad is formed integrally with the second container 200 and is seated on the ground to form a vacuum between the ground and the vacuum pad.

That is, the vacuum pad is adhered to the ground and the vacuum, there is an advantage that can be fixed without falling down or moving the container to be final produced by the external magnetic pole.

Furthermore, one side of the vacuum pad may be applied to the second space 211 so that the vacuum pad may be assembled or separated from any one selected from the protrusions or the grooves formed in the second space 211 so as to be adapted to the user's use. It may be formed in a shape corresponding to any one selected from the formed protrusions or grooves, but is not limited thereto.

In addition, the lower protrusion 210 may further include a lower protrusion 212 protruding downward along the edge of the lower surface 210 so that the lower surface 210 may be stably seated on the ground.

Since the lower end of the lower protrusion 212 is formed to contact the ground, the minimum area of the lower surface 210 is formed to touch the ground, so that the area between the container and the ground to be finally manufactured is minimized by the temperature of the ground There is an advantage to minimize the change in temperature.

Optionally, a vacuum pad extending outwardly may be further included on an outer surface of the lower protrusion 212.

The vacuum pad is formed to extend outwardly from the lower protrusion 212 so that the lower end of the lower protrusion 212 is seated on the ground, and at the same time, the vacuum pad is adhered to the ground so that the final container and the ground can be firmly fixed. There is this.

To this end, a groove may be formed in any one selected from outside or inside the bottom protrusion 212 so that the vacuum pad may be interlocked with the bottom protrusion 212, but the vacuum pad may be fixed, but is not limited thereto. Of course.

At this time, the vacuum pad may be formed so that the end is extended from the groove to facilitate assembly or separation.

Next, the second side surface 220 may extend upwardly along the edge of the lower surface 210.

Since the second side surface 220 is formed to correspond to the shape of the first container 100, it is possible to maintain the temperature of the contents accommodated inside the first container 100 for a long time.

Moreover, by minimizing the discharge of the temperature of the contents to the outside, there is an advantage that the user can grab the second side 220 and easily move the final manufactured container.

Therefore, a second protrusion 221 recessed in an outward direction may be further included on one inner side of the second side surface 220 to correspond to the first protrusion 121.

In this case, one side of the outer side of the second side surface 220 may be formed in a smooth shape or protruded in a shape corresponding to the second protrusion 221.

Preferably, by forming in a smooth shape, the outer surface of the container to be finally manufactured may be formed beautifully, but is not limited thereto.

That is, since the second protrusion 221 is further formed, any one selected from the first container 100 or the second container 200 is expanded or expanded due to the temperature change of the contents contained inside the first container 100. It is contracted and has a merit that a gap is generated between the first container 100 and the second container 200 to prevent separation of the first container 100 and the second container 200.

At this time, the first container 100 inside the second container 200 may be integrally formed by coupling by fitting, but is not limited thereto.

Furthermore, when the first container 100 and the second container 200 are integrally formed by fitting with each other, the first container 100 and the second container 200 formed of different materials may be welded together. There is an advantage that the bonding can be maintained firmly without performing a separate fixing process.

Next, the second end 230 may extend in an upward direction at an upper end of the second container 200.

Since the second end 230 is formed, the second end 230 is introduced into the first end 130 so that the first vessel 100 and the second vessel 200 may be integrally and firmly fixed. There is this.

To this end, the second end 230 may be formed to a thickness that can be inserted into the first end 130.

Preferably, the second end 230 is formed to be the same as or thinner than the second side surface 220 so that the second end 230 may be easily inserted into the first end 130, but is not limited thereto.

If the second end 230 is formed thinner than the second side surface 220, the second end protrusion 231 formed in a step shape on the outside of the portion where the second end 230 and the second side surface 220 are connected to each other. May be further included.
