Description

TECHNICAL FIELD

The present invention relates to a food freezer container in which seasonings, ingredients, or water are stored in an internal receiving part formed with a plurality of storage spaces in a frozen or refrigerated manner so that they may be easily taken out and used as much as necessary, and in which protrusions are formed on the bottom surface of the receiving part and, to increase elasticity, restorative force, and strength, a circular first protrusion and a doughnut-shaped bulge in the center of the first protrusion are formed, and a convex second protrusion is formed in the inner center of the receiving part by a recess formed to be concave in the center of the bulge, preventing the frozen food from continuously contacting the bottom surface over a large surface.

BACKGROUND ART

In general, a freezer container is used to contain and freeze water or beverages and is provided in a plastic plate shape having a plurality of compartments. Since the freezer container has compartments shaped and sized to freeze beverages, it is not suitable for food products such as minced garlic, baby food, porridge, or such ingredients. Further, since it is formed of a relatively solid material and is used in a method of turning the entire container over in order to take out the contents, it may not fit the purpose of removing the contents one by one.
In order to solve these issues, Korean Patent No. 10-1519819 by the applicant discloses an ice-making container for food that is intended for freezing not only ice or beverages, but also various food ingredients and simply taking only as much as necessary. However, in the ice-making container, the part for receiving frozen food has a hemispherical shape so that when pressed for withdrawal, the bottom surface does not easily return to its shape, resulting in the inconvenience that is needed to press the bottom surface of the receiving part in the opposite direction so as to restore the shape.
When the bottom surface is pressed to withdraw the frozen food ingredient, the food ingredient may be pulled out, broken or cracked.

BEST MODE TO PRACTICE INVENTION

Hereinafter, preferred embodiments of the present invention are described with reference to the accompanying drawings to be easily practiced by one of ordinary skill in the art.
The present invention relates to a food freezer container having internal receiving parts 120 formed as a plurality of storage spaces as shown in FIGS. 1 to 7, in which a certain amount of food, such as seasoning, ingredients, or water, is stored in the internal receiving parts 120, and then stored in a frozen or refrigerated manner to be easily taken out as much as necessary.
The food freezer container includes a body part 100 having receiving parts 120 formed as a plurality of storage spaces partitioned by a grid part 110 thereinside and
a cover part 200 covering the receiving parts 120 from above the body part 100 to prevent foreign bodies from flowing into the inside.
The body part 100, as a container body, may be coupled with the cover part 200 formed of a container lid. The body part 100 may include a grid part 110, a plurality of receiving parts 120 partitioned by the grid part 110, end parts 130, and handle parts 140. The body part 100 may be formed of a synthetic resin material.
The body part 100 may be formed of various materials but, preferably, the body part 100 is formed of a material, e.g., polyethylene, that maintains flexibility and elasticity in a finished product state, is advantageous for injection molding and resistant to low temperatures.
The body part 100 includes the multiple receiving parts 120 each having a top opening to store a predetermined amount of food such as seasonings, food ingredients, or water. The receiving parts 120 are arranged in a lattice structure by the grid part 110 formed in the horizontal and vertical directions.
The grid part 110 includes separating protrusions 111 that protrude from the top of the grid part 110 and prevents the contents in the receiving parts 120 from overflowing and freezing on the top of the grid part 110.
The separating protrusions 111 are intended to solve the problem that it is difficult to remove only the content of a receiving part 120 as the content overflows the receiving part 120 and is mixed and frozen with the content of another receiving part 120. The separating protrusion protrudes in a predetermined length on the center portion of the grid part 110 which separates the receiving part 120 from the other receiving part 120. The separating protrusions 111 prevents deformation of the grid part due to an increase in volume when the food to be stored is frozen, and the separating protrusions 111 provide a strong supporting force to the grid part. Thanks to the separating protrusions 111, even if the contents (food) rise up onto the top and freeze, the grid part may be prevented from deformation, and the thickness of the contents connected between the two adjacent portions of the grid part may decrease.
As the separating protrusions 111 are provided as thus, there may be formed recesses that allow for easier removal of the contents in a receiving part 120 although the contents overflow and mix and freeze with the contents in another receiving part 120.
The receiving parts 120 may be structured to have a quadrangular shape and to be continuously arranged. The receiving parts 120 may be formed in various shapes of lattice structures.
The receiving part 120 may be formed in a relatively small size to store a small amount of seasonings such as finely chopped ginger or garlic, or may be formed in a relatively large size to store cut green onions or peppers. The size of the receiving part 120 may be varied depending on the customer's preferences.
Further, the respective storage spaces of the receiving parts 120 may be formed in different sizes.
The end parts 130 may protrude upwards along the edge of the receiving parts 120, and the handle parts 140 may protrude from both sides of the receiving parts 120.
The receiving part 120 includes a first protrusion 121, a bulge 122, a recess 123 a, and a second protrusion 123. The first protrusion 121 is formed of a bendable material, such as silicone, rubber, or synthetic resin, and is deformed to rise in an upper direction (upward) when an external force is applied from thereunder. The first protrusion 121 protrudes in a lower direction (downward). The bulge 122 is formed in the center of the first protrusion 121 so as to provide elasticity and restoring force, and high strength against the deformation of the first protrusion 121 due to an external force applied to the first protrusion 121 to press the bottom surface 120 a and make it stick upwards. The recess 123 a is depressed inwards in the center of the bulge 122. The second protrusion 123 has a convex internal center portion corresponding to the recess 123 a.
The bottom surface 120 a of the receiving part 120, unlike that of the conventional freezer container, has a curvature to allow it to be convex downward, and the bottom surface 120 a protruding toward the bottom of the body part 100 is formed to be elastically bendable inwards or restorable. The bottom surface 120 a is formed with the circular first protrusion 121 and the doughnut-shaped bulge 122 in the center of the first protrusion 121. The recess 123 a which is concave inwards of the container is provided in the center of the bulge 122. The second protrusion 123 is formed in the inner center of the receiving part 120, and the portion of the second protrusion 123, which corresponds to the recess 123 a, is convex. That is, the first protrusion 121 and the second protrusion 123 protrude in opposite directions, and the first protrusion 121 and the bulge 122 protrude in the same direction.
As shown in FIG. 3, the receiving part 120 is formed so that a thickness t2 of a side surface 120 b of the receiving part 120 is larger than a thickness t1 of the bottom surface 120 a. Thus, when the bottom surface 120 a is pressed, the side surface 120 b is not deformed, so that the frozen food received in the receiving part may be easily removed and, even if deformed, the receiving part 120 may be easily restored.
Further, in the bottom surface 120 a, a thickness a of the bulge 122, a thickness b of the second protrusion 123, and a thickness c of a portion between the bulge 122 and the second protrusion 123 are larger than the thickness of a portion between the bulge 122 and the first protrusion 121, preventing cracks at the inner center of the bulge 122, which has the longest movement distance when the food is removed from the freezer container by pressing the bottom surface 120 a. Further, as the inside of the container leading to the bulge 122 and the second protrusion 123 protrudes inward, the food is avoided from coming into continuous flat contact with the inner bottom of the container, so the food is easily removed from the container even with small deformation of the container.
The thickness b of a portion of the second protrusion 123 protruding inward of the container is the same as the thickness c of a portion between the second protrusion 123 and the bulge 122. Accordingly, it gradually rises from the bulge 122 protruding outward of the container, and rises, in the same thickness, inward of the container from about the middle between the second protrusion 123 and the bulge 122 and rises up to the second protrusion 123 and reaches the peak. Meanwhile, it is preferable that the thickness a of the bulge 122 is generally smaller than b and c. The bulge 122 is where an external force for removing the frozen food from the container is applied. Thus, if the bulge 122 becomes thicker so that it sticks out a lot, the user's hand may feel pain when pressing the bulge 122. If the receiving part is formed in a size large enough to press the first protrusion 121 as well as the bulge, it is ok to make the thickness of the bulge 122 slightly larger than the thickness of the second protrusion.
Meanwhile, the thickness of the portion between the bulge 122 and the second protrusion 123 is larger than the thickness between the bulge 122 and the first protrusion 121. Thus, the portion between the bulge and the first protrusions 121 is easily deformed by an external force, but the portion between the bulge 122 and the second protrusion 123 is not easily deformed by an external force. In the freezer container of the present invention, having such a configuration, the portion between the second protrusion 123 and the bulge, which is the center of the container with the largest deformation distance, is not deformed, thus causing no or few cracks while allowing for easier deformation of the portion between the bulge and the first protrusion and hence deforming the food and the container. Further, as the bulge 122 and the second protrusion 123 protrude inward of the container, the continuous flatness in the circular first protrusion 121 may be removed, rendering it difficult for the food to come into strong contact with the freezer container and to be thus easily removed from the container.
The height of the outer edge of the first protrusion 121 is larger than that of the center of the second protrusion 123. The circular first protrusion 121 protrudes downward from the outer edge, and the second protrusion 123 is provided in the center thereof. The second protrusion 123 protrudes the highest inside the container. In this case, the second protrusion 123 is formed to be lower than the outer edge of the first protrusion 121 even when it is in the highest position as shown in FIG. 3. The second protrusion 123 is located in the center of the bottom surface to prevent the food and the container from coming in flat contact with each other over a large area so that the food may be easily removed from the container when an external force is applied to the first protrusion. However, if the second protrusion 123 is formed too high, the food may get stuck to the second protrusion, making it difficult to remove the food.
For aiding in removal of the frozen food, the inner surface of the receiving part 120, including the inside of the bottom surface 120 a, may be treated to have an inner surface roughness small enough to make it smooth, and the inner surface may be treated to have a small roughness to allow the inner surface of the receiving part 120 to be glossy, so that when the bottom surface 120 a is pressed, the frozen food may be easily slid and removed from the receiving part 120.
Further, the outer surface of the receiving part 120 may be treated to have a large surface roughness, that is, at a level which no gloss is not observed with the naked eye, preventing the body part 100 from sliding on the hand.
The edge portion of the body part 100, which surrounds the receiving parts 120, is formed to be higher than the receiving parts 120, thus forming the end part 130 which is coupled to the cover part 200. The body part 100 includes the handle parts 140 that extend from both sides of the body part 100.
Jaws 141 may be formed to be vertically bent and extend downwards from the ends of the handle parts 140, preventing the handle parts 140 from slipping when the handle parts 140 are held by hand.
A character display part (not shown) may be provided on one side on the top of the handle part 140 to display the volume of the receiving part 120, and the character display part may be shape-formed depending on the material of the body part 100 or printed on the surface of the body part 100.
The receiving part 120 may be provided in various volumes, and the character display part (not shown) indicates the volume of the receiving part 120 in ml, mg, or spoon units to easily measure the volume of the frozen food.
The cover part 200 has a concave edge that is coupled with the end part 130, which is formed to be convex along the edge of the body part 100, to be elastically compressed and tightly sealed to thus seal the inside and prevent leakage of water or soup.
The cover part 200 is detachably provided on the top of the receiving parts 120 and is coupled to the body part 100 to block foreign bodies from entering the receiving parts 120.
The cover part 200 is formed of the same material as the body part 100. The cover part 200 may be formed of a material such as silicon, rubber, or synthetic resin.
The cover part 200 is provided with a cover part handle 210 that extends from one side of the cover part 200 to easily open the cover part 200. Thus, the cover part 200 may be easily open from the body part 100 using the cover part handle 210.
In the food freezer container of the present invention, the user puts food, such as seasonings of ground garlic or ginger, food, or water, in each of the receiving parts 120 of the body part 100, closes the cover part 200, and stores it in a freezer or refrigerator, and when necessary, pulls out the food by pressing the bottom surface 120 a of the receiving part 120.
In this case, even if the food contained in the receiving part 120 reaches the top surface of the grid part 110, which forms the sidewalls of the receiving parts 120, it may be tightly sealed by closing the cover part 200. The cover part 200 may be coupled to the end part 130 provided at the edge of the body part 100 to air-tightly seal the food stored in the receiving part 120 from the outside. In other words, even when the food is raised up to the top and, when frozen, increases in volume to apply pressure to the grid part, the food may remain balanced, and the food positioned between two adjacent portions of the grid part may be easily removed by the separating protrusions 111 provided between two adjacent portions of the grid part.
The user may have a plurality of the body parts 100 closed with the cover parts 200 and, thus, efficiently use the space of the freezer upon stacking them.
When the body part 100 closed with the cover part 200 is frozen in the freezer, the user may take out the body part 100 whenever necessary, open the cover part 200, and pull and use the frozen food.
The user grabs the handle parts 140 provided on both sides of the body part 100 and takes the body part 100 out of the freezer. The handle part 140 has the jaw 141 formed at an end thereof, allowing the user to easily grab the handle part 140 and preventing it from slipping out and hence allowing for stable movement of the body part 100.
The user presses the bottom surface 120 a of the receiving part 120 toward the inside of the receiving part 120 to remove the frozen ingredient from the receiving part 120. The bottom surface 120 a is formed to be thinner than the side surface 120 b of the receiving part 120, so that, when the user applies force, the bottom surface 120 a may be easily pressed while the side surface 120 b maintains its shape. Thus, the contents of the receiving part 120 may be easily removed.
Meanwhile, as the volume of the food contained in the receiving part 120 increases while it freezes, the food may overflow the receiving part 120 and may thus be frozen while being connected to the contents of another other receiving part. Thus, when the user presses the bottom surface 120 a of the receiving part 120, not only the food in the desired receiving part but also the surrounding food may be removed as a lump. In such a case, the contents are partially separated and frozen by the separating protrusion 111 provided on the top surface of the grid part 110, so that the user may easily separate the frozen contents connected together.
After the frozen food is separated, the bottom surface 120 a of the receiving part 120 returns to its original shape by elasticity, and the receiving part 120 is then closed with the cover part 200 so as to hygienically store the remaining food in the freezer.
Therefore, the food freezer container of the present invention includes the receiving parts 120 formed as a plurality of storage spaces that have a top opening and are partitioned inside by the grid part 110 to contain a certain amount of food such as seasonings, food ingredients, or water and store in a freezer. The bottom surface 120 a of the receiving part 120 includes protrusions. To increase elasticity, restorative force, and strength, the bottom surface 120 a includes the circular first protrusion 121, the doughnut-shaped bulge 122 formed in the center of the first protrusion 121, and the convex second protrusion 123 formed in the inner center of the receiving part by the concave recess 123 a formed in the center of the bulge 122, so that the frozen food does not flatly contact the bottom surface 120 a. Thus, the frozen food received in each receiving part 120 may be easily removed without being broken or cracked, by pressing the bottom surface 120 a.
In the food freezer container of the present invention, the thickness of the side surface 120 b of the receiving part 120 is larger than the thickness of the bottom surface 120 a. Thus, when the bottom surface 120 a is pressed, the side surface 120 b is not deformed, so that the frozen food received in the receiving part 120 may be easily removed and, even if deformed, the receiving part 120 may be easily restored, thus removing any inconvenience that would be caused if the deformation remains.
The food freezer container of the present invention is formed so that, in the bottom surface 120 a, the thickness of the bulge 122 is the same as the thickness of the second protrusion 123, and the thickness of the portion between the bulge 122 and the second protrusion 123 is larger than the thickness of the portion between the bulge 122 and the first protrusion 121. Thus, the frozen food may be prevented from cracks when the bottom surface 120 a is pressed.
The food freezer container of the present invention is provided so that the bottom surface 120 a is bent with elasticity, so that the contents may be removed independently from each receiving part 120. Thus, each serving of various seasonings, baby food, porridge, or drugs may be frozen and stored, and the remaining food ingredients may be sanitarily frozen and stored. Further, as the container may have receiving parts 120 in various volumes, it is possible to freeze and store each serving of various food ingredients from small volumes of food ingredients such as chopped garlic to relatively large volumes of food ingredients such as baby food and to use them whenever necessary.
