Description

[Amendment according to Rule 26 19.07.2019] 　Container to minimize deformation due to heat and its manufacturing method

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

In general, containers for storing food or washing or used as a bowl are made of synthetic resin or metal material to block deterioration and contamination of food and are formed to be preserved for a long time.

Since these containers are easy to transfer temperature, in the case of storing hot or cold food, a tray or moving tray is used to move from the cooked kitchen to the location where the user is seated. Often, 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, so that it is difficult and inconvenient to move the container.

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

In addition, in recent years, due to the high degree of development of synthetic resin materials, they are frequently used when storing or containing various foods, both indoors and outdoors.

However, in the case of a synthetic resin material, heat transfer coefficient is lower than that of a container made of a metal material, and heat transfer is not performed rapidly, but there is a disadvantage that it is easily deformed by external stimulation or external temperature change.

Accordingly, in recent years, in order to prevent the temperature of the contents from being transferred to an external container, the container is formed in double so that the user can conveniently use it.

The double-formed container has a disadvantage in that the container is deformed due to external stimulus or temperature change, so that a gap is generated between the outer container and the inner container, thereby being separated.

Looking at the background technology to compensate for this problem, in the “double container and its manufacturing method” of Korean Patent Publication No. 10-1101876 (hereinafter referred to as'document 1'), the inner side of the outer container including the spaced guide protrusion Disclosed is a container formed such that the inner container is combined to block the temperature of the contents from being transferred to the outer container.

In the case of using the invention of Document 1, there is an advantage in that it is possible to block the temperature of the contents contained in the inner container from being transferred to the outer container by the spaced guide protrusions included in the outer container.

However, as shown in Fig. 1, the inner container is integrally formed by combining the protruding jaws of the outer container, and the outer container and the inner container are integrally formed by welding using frictional heat, so that the outer container and the inner container are combined. Not only is this cumbersome, but by applying high-temperature frictional heat to the protruding jaw of the outer container in order to keep the bonding firm, the protruding jaw is deformed and there is a disadvantage that the coupling between the inner container and the outer container cannot be performed, resulting in a defect. .

Looking at other background technologies, in the “Cooling Cup” of Korean Utility Model Publication No. 20-0366346 (hereinafter, “Document 2”), cooling fins and cooling protrusions are formed in the inner cup by the refrigerant introduced into the closed space. Disclosed is a cooling cup in which beverages such as beer contained in a cooling cup can be cooled in a short time by increasing the cooling effect of beverages, while maintaining coolness.

In the case of using the invention of Document 2, the cooling fins in contact with the inner circumference of the outer cup and the cooling protrusion formed in the center of the inner cup provide a refreshing sensation to the drinker in a short time when drinking. There is an advantage of maintaining the freshness of the beverage for a long time.

However, as shown in FIG. 2, when the refrigerant is formed to inject the refrigerant into the closed space formed between the inner cup and the outer cup and the refrigerant evaporates, there is a hassle of injecting the refrigerant into the screw hole from time to time. There is a disadvantage that the inner cup can be easily separated from the outer cup due to external stimulation because the inner cup is joined by the coupling jaw.

Looking at other background technologies, in the “plastic double insulation container” of Korean Utility Model Publication No. 20-0473714 (hereinafter, “Document 3”), synthetic resin is vacuum-molded to overlap the inner container and the outer container. Disclosed is a heat insulating container having a plurality of air pockets formed by repeating a portion separated from each other and a portion in close contact between the outer surface of the inner container and the inner surface of the outer container.

In the case of using the invention of Document 3, there is an advantage in that it is possible to minimize changes in food due to external temperature by increasing heat insulation and heat insulation by an air pocket, so that the cooked food can be maintained in an optimum state for a long time.

However, as shown in Fig. 3, the inner container and the outer container are formed of synthetic resin, so that deformation can easily occur due to the external temperature, and the inner container and the outer container are combined by the combination of the upper side of the outer container. There is a drawback that can be easily separated.

Looking at another background technology, in the "cooking container equipped with an overheating prevention function" of Korean Patent Application 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. Accordingly, a cooking vessel in which heat transfer is performed by conduction is achieved by contacting the inner wall and the outer wall below a certain temperature, and the inner wall and the outer wall are separated from each other at a certain temperature or higher to block heat transfer by conduction.

In the case of using the invention of Document 4, as shown in FIG. 4, the container is heated for a long time and the inner wall of the cooking container has the advantage of maintaining a constant temperature. However, due to repeated expansion or contraction by heat, deformation due to frequent use is prevented. There is a drawback that the outer wall and the inner wall can be easily separated by being generated.

In describing the present invention, when it is determined that a detailed description of a related known technology may obscure the subject matter of the present invention, a detailed description thereof will be omitted.

As shown in FIGS. 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.

A container for minimizing deformation due to heat according to 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 capable of accommodating contents therein.

At this time, the upper side of the first container 100 is formed in an open shape, so that the contents may be formed of either a metal material or a synthetic resin so that the contents can be accommodated and stored from the upper side of the first container 100 to the inside.

Preferably, the first container 100 may be formed of a metal material to minimize the temperature change rate of the contents accommodated inside by the external environment, and most preferably, it may be formed of a stainless steel-based metal material having excellent corrosion resistance. have.

At this time, since the first container 100 is formed of a metal material, expansion and contraction due to temperature change are less than that of synthetic resin, and thermal conductivity is lower than that of other metals, so that the temperature of the contents can be maintained 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 metal, a drawing processing method in which the metal formed in the form of a plate is placed on one or more molds and compressed by a pressure machine to form a predetermined shape may be applied.

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

Moreover, the first container 100 may be formed including a first protrusion 121 and a first end 130.

First, the first protrusion 121 may be formed to protrude outwardly on an outer side of the first container 100.

At this time, the first protrusion 121 is formed in a strip shape along the outer surface of the first container 100 so that the gap generated between the first container 100 and the second container 200 is minimized by frequent washing. In addition, there is an advantage of minimizing separation due to the occurrence of gaps as the container expands or contracts by heat.

Optionally, one inner side of the first container 100 may also be formed to be depressed in an outward direction according to the shape of the first protrusion 121, which has the advantage of preventing the container from being separated from the user's hand during the washing process. have.

In addition, when the first container 100 is formed to guide the user so that the contents can be accommodated in an appropriate amount, when combined with a cover including a lid, etc., the overflow phenomenon can be prevented by the amount of the contents received. There is an advantage.

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

The cross section of the first end 130 is formed in a ring shape so that when the contents overflow from the inside of the first container 100, the contents can be prevented from flowing between the first container 100 and the second container 200. Can be formed.

At this time, by providing sufficient space inside the first end 130 so that the second end 230 can be inserted, the first container 100 and the second container 200 are formed so that they are not separated by heat change. I can.

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

By being formed in this way, the first container 100 prevents the first end 130 from being deformed by external stimuli such as washing, so that the combination of the first container 100 and the second container 200 is more robust. 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, not only the first container 100 and the second container 200 are more firmly coupled, but also moisture or water inside the first end 130 There is an advantage in that penetration is prevented and durability of the finally manufactured container is improved.

At this time, 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 of less than 30 is applied, there is a disadvantage that it can be easily broken in the process of combining the first container 100 and the second container 200 due to the low hardness, and if the shore hardness is 80 or more, high There is a disadvantage in that the manufacturing cost for maintaining the hardness increases.

Moreover, when the commercial temperature is less than -75°C or more than 200°C is applied, there is a disadvantage in that the manufacturing cost for manufacturing a silicone rubber having a wide commercial temperature range is increased.

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

Since the second container 200 is formed to surround the outer surface of the first container 100, not only the temperature change of the contents accommodated inside the first container 100 is minimized, but also the first container changed by the temperature of the contents. It may be formed so that the temperature of the container 100 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 hold the second container 200 and move the finally manufactured container due to the thermal insulation properties of the second container 200.

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

Most preferably, an 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 metal, a drawing processing method in which the metal formed in the form of a plate is placed on one or more molds and compressed by a pressure machine to form a predetermined shape may be applied.

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

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

First, the lower surface 210 is formed under the second container 200, and one side is raised to form a second space part 211 outside the lower side.

That is, the lower side of the second container 200 is raised to form the second space part 211, so that a space equal to the size of the second space part 211 is formed between the ground and one side of the lower surface 210 of the container to be finally manufactured. By being formed, there is an advantage of minimizing the temperature change of the contents due to the temperature difference between the ground and the contents.

Optionally, the lower side of the first container 100 is 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 211 of the second container 200. have.

Therefore, one side of the lower outer surface of the first container 100 may be seated on the upper side of the second space part 211, but is not limited thereto.

In addition, as the second space portion 211 is formed, the outer edge of the lower surface 210 may be formed to contact the ground.

Optionally, one or more protrusions or grooves may be further included inside the second space part 211.

At this time, a vacuum pad may be formed in connection with any one of the protrusions or grooves so that the vacuum pad is integrally formed with the second container 200 and at the same time is seated on the ground to form a vacuum between the ground and the vacuum pad.

That is, since the vacuum pad is adhered to the ground in a vacuum, the container finally manufactured by the external stimulus can be fixed without falling or moving.

Moreover, one side of the vacuum pad is attached to the second space 211 so that the vacuum pad can be assembled or separated from any one selected from among the projections or grooves formed in the second space 211 and applied according to the user's usage. It may be formed in a shape corresponding to any one selected from among the formed protrusions or grooves, but is not limited thereto.

Furthermore, a lower protrusion 212 formed outside the lower surface 210 may be further included to protrude downwardly along the rim so that the lower surface 210 can 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 contact the ground, thereby minimizing the area where the final manufactured container and the ground contact the surface. It has the advantage of minimizing temperature change.

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

Advantages that the vacuum pad is formed extending outward from the lower protrusion 212 so that the lower end of the lower protrusion 212 is seated on the ground and the vacuum pad adheres to the ground so that the final manufactured container and the ground can be fixed more firmly There is this.

To this end, a groove may be formed in any one selected from the outer or inner side of the lower protrusion 212 so that the vacuum pad can be interlocked with the lower protrusion 212 so that the vacuum pad may be fixed, but is not limited thereto. Of course.

In this case, the vacuum pad may be formed so that the end of the vacuum pad extends from the groove to facilitate assembly or separation.

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

At this time, the second side 220 may be formed to correspond to the shape of the first container 100 so that the first container 100 can be firmly wrapped, but the first container 100 is replaced with the second container 200. Of course, if it is in a form that can be wrapped from, it is not limited thereto.

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

In addition, by minimizing the temperature of the contents to be released to the outside, there is an advantage that the user can hold the second side 220 and easily move the final manufactured container.

Accordingly, a second protrusion 221 that is recessed outwardly so as to correspond to the first protrusion 121 may be further included on one inner side of the second side surface 220.

In this case, one 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 being formed in a smooth shape, the outer surface of the container to be finally manufactured may be beautifully formed, but is not limited thereto.

By including the second protrusion 221, the first protrusion 121 formed in the first container 100 is seated inside the second protrusion 221 so that the first container 100 and the second container 200 It can be firmly fixed.

That is, as the second protrusion 221 is further formed, any one selected from the first container 100 or the second container 200 is expanded or expanded by a temperature change of the contents accommodated inside the first container 100. It is contracted, and there is an advantage of preventing the first container 100 and the second container 200 from being separated because a gap is generated between the first container 100 and the second container 200.

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

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

Next, the second end 230 may be formed extending upwardly at an upper end of the second container 200.

As the second end 230 is formed, the second end 230 is inserted into the first end 130 so that the first container 100 and the second container 200 can be rigidly fixed integrally. There is this.

To this end, the second end 230 may be formed to have 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 220 so that the second end 230 can 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 220, the second end protruding portion 231 formed in a stepped shape outside the portion where the second end 230 and the second side 220 are connected May be further included.

Therefore, the second end 230 is inserted into and fixed inside the first end 130 and at the same time, the end of the first end 130 can be formed so that the end of the first end 130 can be stably seated and fixed on the upper side of the second end protrusion 231. There is.

Moreover, the first end 130 may be inserted into one side of the second end 230 by the shape of the first end 130 to fix the first container 100 from the second container 200.

In this case, the bottom of the first end 130 may be formed so that the first container 100 and the second container 200 can be stably fixed by being seated on the second end protruding part 231, but is not limited thereto. Of course not.

Optionally, when a ring is further included between the inner side of the first end 130 and the upper side of the second end 230, the first container 100 and the second container 200 may be more firmly coupled.

That is, the ring fills the space that may occur between the first end 130 and the second end 230, so that moisture that may penetrate between the first end 130 and the second end 230 in the cleaning process Or, by preventing water, there is an advantage that the durability of the finally manufactured container can be further improved.

A support part 300 protruding upwardly inside the lower surface 210 of the second container 200 formed as described above may be further included.

That is, since the support part 300 is further formed, the first container 100 can be stably seated and fixed inside the second container 200.

In addition, there is an advantage of minimizing deformation of any one of the lower surface 210 or the second side surface 220 by the support part 300 due to external temperature or external stimulation such as a dishwasher.

That is, the lower side of the support part 300 may be formed to correspond to the shape of the upper side of the lower surface 210 as shown in FIG. 8.

Moreover, the overall shape of the upper side of the support part 300 is formed to wrap the lower side of the first container 100 so that the first container 100 can be stably seated and fixed from the second container 200 Can be.

One end selected from one side of the upper side or the other side of the upper side of the support part 300 may be formed to protrude upward so that the first container 100 may be more stably supported by the support part 300.

That is, the support part 300 may protrude toward the center of the lower surface 210 in an inward direction under the second side surface 220 of the second container 200.

Optionally, one or more support parts 300 may be formed in a radial form centered on the center of the lower surface 210 of the second container 200.

In this case, a third space part 310 may be formed between the one or more support parts 300.

Since the third space 310 is formed, the temperature of the contents contained in the first container 100 flows into the third space 310 so that the temperature of the contents contained in the first container 100 remains constant for a long time. There is an advantage that can be maintained.

The container formed as described above has the advantage that the temperature change of the contents contained inside the first container 100 can be minimized due to the external temperature since the lower surface 210 of the second container 200 is raised upward.

In addition, at least one support part 300 is protruded above the lower surface 210 of the second container 200 and is selected from the lower surface 210 or the second side surface 220 by external temperature or external stimulation such as a dishwasher. There is an advantage of minimizing the deformation of any one of them, and that the first container 100 can be stably and firmly seated inside the second container 200.

Moreover, since the first container 100 is compressed and bonded to the inside of the second container 200, there is an advantage that the bonding can be maintained firmly without further performing a separate process such as welding.

Hereinafter, as shown in FIG. 14, a method of manufacturing the container of the present applicant will be described in more detail with respect to the container of the present applicant.

1) A first step (S110) of preparing preparations for manufacturing the first container 100 and the second container 200 is performed.

At this time, any one selected from the first container 100 or the second container 200 may be formed of a metal material or a synthetic resin.

Preferably, the first container 100 may be formed of a metal material, and the second container 200 may be formed of a synthetic resin, but is not limited thereto.

2) A second step (S120) of manufacturing the first container 100 using the material that has passed through the first step (S110) is performed.

In this case, the first container 100 formed of a metal material may be applied with a drawing process so that the metal formed in the form of a plate is placed on one or more molds and compressed by a pressure machine to form a predetermined shape.

Optionally, when the material of the first container 100 is formed of synthetic resin, an injection molding method in which a synthetic resin material is injected into one or more molds to facilitate molding of the material may be applied, but is not limited thereto.
