Description

Technology Field

[0001] The present invention relates to a folding container in which the container body can be folded, and more specifically, to a folding container in which a hand gripping portion is provided on the main body and the cover, and when the main body and the cover are combined, the gripping portion of the main body and the gripping portion of the cover are also sealed and locked, so that the cover is not separated from the main body by gripping the gripping portion of the main body and the gripping portion of the cover together, and the main body and the cover are sealed more tightly with a quadruple sealing structure, and the gripping portion of the main body and the cover are bent toward the main body so as to improve the phenomenon of the container shifting to one side when moving while holding the gripping portion. Background Technology

[0003] A container is a kitchen utensil used to hold and store items such as food, fruits, vegetables, small items, and powdered products; generally, a container consists of a main body that holds the items and a cover that covers the opening of the main body.

[0004] These containers are made of materials such as plastic, glass, ceramics, and metal, but recently, containers made of rubber materials such as silicone, which are harmless to the human body and pose no risk of breakage, are becoming widely used.

[0006] Registered Patent 10-1312607 "Silicone container" is disclosed as prior art regarding a folding container made of rubber material that can be folded.

[0007] The above registered patent 10-1312607 "silicone container" allows the main body to be folded so that the height can be adjusted. In addition, a sealing member is provided between the main body and the lid (cover) to increase the sealing power.

[0009] Folding containers are prone to deformation, such as bending or crushing when pressure is applied. In other words, if a user holds a folding container with their hand or places another container or object on top of it, the folding container may be crushed by that pressure.

[0010] If deformation occurs in the folding container, the sealing power of the main body and the cover may weaken, allowing external air to penetrate and accelerate the spoilage of food contained in the main body, and potentially cause the liquid inside to leak out.

[0012] Folding containers according to the prior art have a problem in that the bonding force between the main body and the cover is weak, causing the cover to open from the main body unintentionally, which then causes the contents contained in the main body to spill out.

[0013] In addition, there is a problem where the liquid contents in the main body leak out through the gap between the main body and the cover due to the weak sealing force of the main body and the cover. The problem to be solved

[0015] The present invention is developed to solve the problems associated with folding containers according to the prior art, and aims to provide a folding container that is easy to take out from a storage location such as a refrigerator by providing a hand gripping part on the main body and the cover, and the gripping part of the main body and the gripping part of the cover are locked and coupled to each other, so that the cover does not separate from the main body in unintentional situations by holding the locked and coupled gripping part of the main body and the gripping part of the cover together with the hand, and the gripping part is adjacent to the center of gravity line of the container so that tilting or shaking of the container is minimized when moving by holding the gripping part, and no external force is applied to the main body during movement so that deformation such as crushing of the main body does not occur, and the sealing force between the main body and the cover is tightly maintained not only in normal conditions but also when pressure is applied. means of solving the problem

[0017] The folding container according to the present invention for achieving such an purpose is

[0018] A main body comprising a body capable of holding a storage object and being foldable, and a first gripping part extending outward from one side of the body and having a first long hole formed therein through which a finger passes;

[0019] The cover comprises a cover portion that seals and covers the upper part of the body, and a second gripping portion that extends outward from one side of the cover portion and has a second hole formed that corresponds to the first hole.

[0021] And on the upper part of the above body, a reinforcing part thicker than other parts and a connecting part extending outward diagonally from the upper part of the reinforcing part are formed, and

[0022] The edge of the above cover is characterized by having a coupling groove formed therein that closely wraps around the coupling part and is fitted together.

[0024] The joint portion of the above body includes an inner diagonal line extending diagonally from the inner surface, an outer diagonal line extending diagonally from the outer surface, and a connecting line connecting the inner diagonal line and the outer diagonal line.

[0025] A first sealing projection and a first sealing groove that are male and female coupled to each other are formed on the inner diagonal line of the above-mentioned coupling part and the inner surface of the above-mentioned coupling groove, and

[0026] A second sealing projection and a second sealing groove that are male and female coupled to each other are formed at the boundary portion between the inner diagonal line and the connecting line of the above-mentioned coupling part and on the inner surface of the above-mentioned coupling groove, and

[0027] The connecting line of the above-mentioned coupling part and the inner surface of the above-mentioned coupling groove are characterized by having a third sealing projection and a third sealing groove formed thereon that are male and female coupled to each other.

[0029] The boundary portion of the above-mentioned outer diagonal line and the connecting line has an angled corner, and this corner and the corner of the inner surface of the joint part that is in close contact with it function as a fourth sealing projection and a fourth sealing groove, respectively. Effects of the invention

[0031] The folding container according to the present invention is equipped with a hand gripping part so that the container can be easily removed from a storage location. The hand gripping part of the main body and the hand gripping part of the cover are locked together and held by hand, so that the cover does not separate from the main body. Pressure is not applied to the main body during transport, so the container does not deform. When an external force is applied, the connecting part of the main body to which the cover is attached tends to spread outward, so the connecting part of the main body adheres more closely to the connecting groove of the cover. The connecting part of the main body and the connecting groove of the cover have a four-layer sealing structure so that the sealing performance between the main body and the cover is maintained stably and continuously. The hand gripping part is located adjacent to the center of gravity line, so that the phenomenon of the main body tilting or shaking is minimized when moving while holding the hand gripping part. This is an invention that is very useful for industrial development. Brief explanation of the drawing

[0043] As shown in FIGS. 1 and 2, the folding container according to the present invention is broadly divided into a main body (10) and a cover (20).

[0045] The above main body (10) and cover (20) are made of natural rubber material that is harmless to inches, such as silicone.

[0047] The above main body (10) includes a body (13) that forms a storage space (11) in which various stored materials can be contained, and a first gripping part (15) that extends outward from one side of the upper part of the body (13).

[0048] The first gripping part (15) has a first hole (16) formed therein to allow the user's finger to pass through and grasp it.

[0049] Referring to FIG. 3, the side wall of the body (13) has a structure that is slightly inclined outward as it goes upward, and a folding section (12) is formed on the side wall that is thin and gradually thickens as it goes to both sides, so that the body (13) can be folded (i.e., folded). Since a plurality of folding sections (12) are formed, the height of the body (13) can be adjusted stepwise according to the folding area.

[0050] A reinforcing part (17) is formed on the upper side wall of the body (13) to suppress bending deformation, as it is thicker than other parts, and a connecting part (18) is formed on the upper side of the reinforcing part (17) to be in contact with and connected to the cover (20).

[0052] The above cover (20) includes a cover (21) that covers the opening of the main body (10) and a second gripping part (25) that extends outward from one side of the cover (21) and is grasped by the user.

[0053] In the second gripping part (25) above, a second hole (26) is formed that is aligned with the first gripping part (15) and through which the user's finger passes.

[0054] Two protrusions (27) are formed on the inner edge of the cover (20) to surround the inner and outer surfaces of the coupling part (18) of the main body (10), and the two protrusions (27) form a coupling groove (28) that is closely coupled to the coupling part (18) of the main body (10) in a male-female manner.

[0056] As first and second gripping parts (15, 25) are formed on the main body (10) and cover (20) to be held by hand, the container is easy to take out of a storage place such as a refrigerator, and pressure is not applied to the body (13) of the main body (10) and the cover (21) of the cover (20) when the container is moved by holding the first and second gripping parts (15, 25), so they are not deformed, and the main body (10) and cover (20) are held together so that the cover (20) is not separated from the main body (10).

[0058] Hereinafter, with reference to FIG. 4, the structure of the coupling part (18) of the main body (10) and the coupling groove (28) of the cover (20) will be described. Since the structure of the coupling groove (28) corresponds to the structure of the coupling part (18), the structure of the coupling part (18) will be described mainly.

[0059] The coupling portion (18) of the main body (10) is formed to face outward diagonally. This causes the coupling portion (18) to have a tendency to move outward when an external force is applied. When the coupling portion (18) moves outward, a tensile force is applied to pull the cover (20) coupled thereto, causing the coupling portion (18) to come into closer contact with the inner surface of the coupling groove (28), thereby improving the sealing force.

[0060] The surface of the connecting part (18) facing outward diagonal direction is composed of an inner diagonal line (L1) facing diagonally from the inner surface of the main body (10), an outer diagonal line (L3) facing diagonally from the outer surface, and a connecting line (L2) connecting the inner diagonal line (L1) and the outer diagonal line (L3) and facing in the reverse diagonal direction, which is approximately perpendicular to the inner diagonal line (L1).

[0062] To increase the sealing force of the above-mentioned coupling part (18) and coupling groove (28), a quadruple sealing structure is formed in them.

[0063] In a single sealing structure, a first sealing projection (29-1) and a first sealing groove (19-1) that are male-female coupled to each other are formed on the inner diagonal line (L1) of the coupling part (18) and the inner surface of the coupling groove (28); in a double sealing structure, a second sealing projection (29-2) and a second sealing groove (19-2) that are male-female coupled to each other are formed on the boundary portion between the inner diagonal line (L1) and the connecting line (L2) and the inner surface of the coupling groove (28); in a triple sealing structure, a third sealing projection (29-3) and a third sealing groove (19-3) that are male-female coupled to each other are formed on the inner surface of the connecting line (L2) and the coupling groove (28); and in a quadruple sealing structure, an angled corner is formed on the boundary portion between the connecting line (L2) and the outer diagonal line (L3), and the corner is seated on the inner surface of the coupling groove (28). A groove is formed so that the corner and the groove function as the fourth sealing projection (19-4) and the fourth sealing groove (29-4).

[0065] In FIG. 4, the coupling part (18) and coupling groove (28) on the side of the first gripping part (15) may have a structure that is somewhat different from other parts. The coupling part (18) and coupling groove (28) here are referred to as the second coupling part (18-2) and the second coupling groove (28-2), and so on, by adding the word 'second'.

[0066] The second connecting part (18-2) is oriented slightly outward in a diagonal direction, but is closer to being oriented vertically. The second outer diagonal line (L3-2) of the second connecting part (18-2) is oriented slightly inward rather than outwardly. The second connecting line (L2-2) is oriented horizontally rather than in a diagonal direction.

[0067] These second coupling part (18-2) and second coupling groove (28-2) have a single sealing structure and a triple sealing structure, but do not have a second sealing structure, and the fourth sealing structure is also weak.

[0069] The single to quadruple sealing structure of the above-mentioned coupling part (18) and coupling groove (28) increases the coupling force of the coupling part (18) and coupling groove (28) to prevent the cover (20) from being unintentionally separated from the main body (10), and also increases the sealing force of the coupling part (18) and coupling groove (28) to prevent leakage of the stored material contained in the main body (10).

[0071] Referring to FIG. 5, the first gripping part (15) of the main body (10) and the second gripping part (25) of the cover (20) are bent toward the body (13) side of the main body (10), that is, toward the center of gravity line. For reference, the center of gravity line is a line that passes through the center of gravity of the container and extends in the longitudinal direction of the main body, and its position varies depending on the weight of the contents contained in the storage space (11) of the main body (10).

[0072] As the first gripping part (15) of the main body (10) and the second gripping part (25) of the cover (20) move further away from the center of gravity line, the tilting of the container becomes more severe when the first gripping part (15) and the second gripping part (25) are lifted by hand. Based on FIG. 5, the lower part of the main body (10) moves more to the left. Also, when moving the first gripping part (15) and the second gripping part (25) by hand, the shaking of the container becomes more severe. If the container tilts or shakes in this way, the bonding force and sealing force of the main body (10) and the cover (20) may weaken, and then the cover may open from the main body or a gap may occur between the cover and the main body.

[0073] Accordingly, the present invention ensures that the first gripping part (15) and the second gripping part (25) are directed toward the center of gravity line, thereby minimizing tilting and shaking of the container when the first gripping part (15) and the second gripping part (25) are lifted by hand and moved.

[0076] In describing the present invention above, a folding container having a specific shape and structure has been described with reference to the attached drawings; however, the present invention is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be interpreted as falling within the scope of protection of the present invention.
