Description

Technology Field

[0001] The present invention relates to a lid for a food container, and more specifically, to a lid for a food container that opens and closes a filling port of a food container filled with liquid food products such as edible oil, soy sauce, vinegar, mayonnaise, ketchup, gochujang, sauces, and dressings, wherein a sealing material is formed on the lid to ensure that the spout formed on the food container is sealed, and at the same time, the food container can be opened by cutting the sealing material that ensures the sealed state of the spout. Background Technology

[0003] Generally, food container lids made of synthetic resin have a built-in sealing material (sealing packing) that is tightly attached to and supported at the top of the spout of the food container.

[0004] In such food container lids, the sealing material is typically made of a soft material, such as rubber, and is secured by being attached to or inserted into the inside of the container lid.

[0005] However, as mentioned above, conventional food container lids composed of sealing materials had a problem of reduced productivity due to the additional work process required to assemble the sealing material.

[0006] Meanwhile, conventionally, there were problems such as the spout of a food container not being properly sealed if the fixed state of the sealing material was unstable and it was not positioned in the correct location.

[0007] In addition, a food container lid that improves upon various problems in addition to the general food container lids described above is presented, and such a food container lid is manufactured through injection molding without involving a separate assembly process.

[0008] As such, the food container lid manufactured through injection molding is structured such that one or more circular ribs are formed between the part that contacts the upper neck and the inner screw part, and when the lid is fastened, the circular ribs come into close contact with the upper part of the spout to seal the food container.

[0009] In particular, these container lids are applied to bottles filled with contents, such as beer, that can be easily preserved even under low pressure.

[0010] In addition, in addition to the food container lid of the example described above, a food container lid with a structure in which a sealing band (safety band) called a guarantee band is applied to ensure the sealing state of the food container is presented.

[0011] Food container lids featuring such a sealing band are designed to protect the contents from unauthorized opening. This sealing band is configured to allow easy detection of whether an unauthorized opening has occurred when the container or lid is opened, particularly for food products distributed filled with liquids such as cooking oil, mayonnaise, ketchup, gochujang, sauces, and dressings.

[0012] Meanwhile, the sealing band described above is typically formed in the shape of a ring and is connected by a plurality of thin connecting webs that are regularly arranged between its upper surface and the lower surface of the container lid.

[0013] When the lid of a food container equipped with a sealing band configured in this way is opened from the food container, the connecting web separates from the lid and remains hooked onto the spout of the food container.

[0014] Therefore, as mentioned above, when recycling food containers with a sealing band hanging on the neck, there was a problem in that the sealing band had to be removed from the spout of the food container through a separate sealing band removal process.

[0015] In addition, as mentioned above, due to the tolerance between the food container and the lid, container lids equipped with sealing bands may come off the spout even when the sealing band is not separated from the lid upon opening, which can lead to a problem where the safety of the contents cannot be guaranteed against unauthorized opening of the lid.

[0016] Moreover, since the sealing band is connected by an extremely simple connecting web, there is a disadvantage that the connecting web is easily damaged. Additionally, the shape of the sealing catch formed on the inner circumference of the sealing band easily deforms due to external temperature changes, causing the container lid to slip out of the food container and release the seal even when not opened, which resulted in a problem where product reliability could not be ensured.

[0017] Meanwhile, in the past, when one wanted to dispose of the food container after using up all the food filled in the container, a tool had to be used to separate the food container lid attached to the spout from the food container, which resulted in not only taking a lot of time during waste disposal but also causing inconveniences such as being very cumbersome and difficult to separate the food container lid attached to the spout.

[0019] Republic of Korea Registered Utility Model No. 20-0419676 (Registered June 16, 2006) The problem to be solved

[0020] The objective of the present invention is to provide a food container lid that improves the reliability of a product contained in a food container by forming a sealing material that is cut by the user's effort between the lid body of the container lid and the opening / closing lid that opens and closes the contents discharge port formed on the upper part of the lid body, thereby enabling the opening of the tube container by cutting the sealing material.

[0021] Another objective of the present invention is to provide a food container lid in which a locking projection is formed on the opening / closing lid to engage and disengage from a locking groove of a sealing material, thereby preventing the opening / closing lid from being opened even if a defect occurs in the sealing material, by the locking projection formed on one side of the opening / closing lid engaging with the locking groove.

[0022] Another objective of the present invention is to provide a food container lid that allows a general user, such as in a home or restaurant, to easily detach and discharge the lid from the food container, which is coupled to ensure airtightness in a food container storing liquids such as cooking oil, soy sauce, or sesame oil. means of solving the problem

[0024] The present invention, for achieving the above-mentioned purpose, comprises a lid body (100) in which a locking projection (110) is inserted into a fixing groove formed on the outer surface of the spout of a food container and coupled thereto; a discharge hole (120) formed on the upper part of the lid body (100) to allow contents stored in the food container to be discharged to the outside; an opening / closing lid (200) rotatably connected to one side of the lid body (100) by a connecting member (300) so as to open / close the discharge hole (120); a sealing material (400) that is cutable and connected between the lower flange surface (210) of the opening / closing lid (200) and the upper flange surface (130) of the lid body (100); and a sealing material (400) that prevents the opening / closing lid (200) from being opened even if a defect occurs in the cut portion between the upper surface of the sealing material (400) and the lower flange surface (210) of the opening / closing lid (200). This is achieved by comprising an auxiliary sealing means (500) and a container lid separation means (600) provided on the outer surface of a lid body (100) having a connecting material (300) formed to be connected to the opening / closing lid (200).

[0025] Meanwhile, it is noted that the above auxiliary sealing means (500) is composed of a locking groove (520) formed in the sealing material (400) and a locking projection (510) formed to protrude from one side of the lower outer surface of the opening / closing lid (200) so as to be inserted into the locking groove (520) and maintain the locking.

[0026] Additionally, it is noted that the above-mentioned container lid separation means (600) is provided by forming a concave incision groove (610) in a vertical direction on the outer surface of the lid body (100) on which the connecting material (300) is formed.

[0027] Meanwhile, it is noted that a plurality of connecting webs (700) are formed to protrude downward from the lower surface of the sealing material (400) and are connected to the upper flange surface (130) of the lid body (100).

[0028] Additionally, it is noted that the sealing material (400) is connected in a detachable manner between the lower flange surface (210) of the opening / closing lid (200) and the upper flange surface (130) of the lid body (100), with a handle portion formed protruding from one side. Effects of the invention

[0030] According to the present invention, the food container is opened by a user's artificial effort to cut a sealing material formed between the lid body of the container lid and the opening / closing lid formed on the upper part of the lid body to open / close the discharge port of the lid body, thereby allowing the food contained in the food container to be consumed safely without illegal opening of the opening / closing lid. At the same time, a double sealing structure is formed by forming a locking projection on one side of the opening / closing lid that engages with and is released from the locking groove of the sealing material. This has the effect of preventing the opening of the opening / closing lid by means of auxiliary sealing means of the locking groove and the locking projection, even if a defect occurs in the sealing material of the sealing structure.

[0031] Meanwhile, according to the present invention, it is a very useful invention that has effects such as making it convenient to separate and discharge the container lid from the food container without using tools or performing any separate work. Brief explanation of the drawing

[0036] As illustrated in FIGS. 1 to 11, the food container lid of the present invention comprises: a lid body (100) in which a locking projection (110) is inserted into a fixing groove (not shown) formed on the outer surface of a spout portion (not shown) of a food container (20) and coupled thereto; a discharge hole (120) formed on the upper part of the lid body (100) so that contents stored in the food container can be discharged to the outside; an opening / closing lid (200) rotatably connected to one side of the lid body (100) by a connecting member (300) so as to open / close the discharge hole (120); a sealing material (400) that is cutable and connected between the lower flange surface (210) of the opening / closing lid (200) and the upper flange surface (130) of the lid body (100); a locking groove (520) cut to a certain size and formed on one side of the sealing material (400); and the It is composed of an auxiliary sealing means (500) in which a locking projection (510), inserted into a locking groove (520) to maintain locking, is formed to protrude from one side of the lower outer surface of the opening / closing lid (200), thereby preventing the opening / closing lid (200) from being opened even if a defect occurs in the cut portion between the upper surface of the sealing material (400) and the lower flange surface (210) of the opening / closing lid (200), and a container lid separation means (600) having a cut groove (610) formed by being concavely cut in a vertical direction on the outer surface of the lid body (100) in which a connecting material (300) is formed to be connected to the opening / closing lid (200).

[0037] Meanwhile, on the lower surface of the sealing material (400), a plurality of connecting webs (700) are formed to protrude downward and are connected to the upper flange surface (130) of the lid body (100).

[0038] Additionally, the sealing material (400) is connected in a way that allows it to be cut between the lower flange surface (210) of the opening / closing lid (200) and the upper flange surface (130) of the lid body (100), with the handle portion protruding from one side. Additionally, the 'handle portion' has a 'concave surface' formed on the inside. Additionally, a 'discharge hole plug' is provided protruding from the inner bottom surface of the opening / closing lid (200). Additionally, a 'slanted enlargement portion' is provided at the upper end of the discharge hole (120). Additionally, a 'groove' is formed in the lid body (100) to which a food container (20) is coupled; a 'slanted surface' is formed on the outer surface of the 'groove', and a 'round portion' is provided at the lower end of the inner surface.

[0039] The present invention, configured in this manner, allows a locking projection (510) formed on the inner surface of the lid body (100) to be inserted into a fixing groove formed on the outer surface of the spout of the food container, thereby connecting the food container lid (10) to the food container so that it is fixed.

[0040] At this time, the container lid (10) is formed such that the lid body (100), which is fixedly coupled to the spout of the food container, and the opening / closing lid (200), which opens and closes the discharge hole (120) formed on the upper part of the lid body (100) by rotating it via a connecting member (300), are kept in a state where they are prevented from opening by a sealing member (400). Additionally, a 'protrusion' is provided on the upper surface of the lid body (100), an 'arc-shaped groove' is formed on the outer surface of the 'protrusion', and 'locking tabs' are provided on both ends of the 'arc-shaped groove'. Furthermore, the outer surface of the opening / closing lid (200) forms an 'inclined surface' that narrows in the downward direction.

[0041] In this way, when a user wants to use liquids such as cooking oil, soy sauce, or sesame oil stored in the food container by releasing the seal of the container lid (10) which is combined with the food container in a sealed state, such as at home or in a restaurant, the seal of the container lid (200) is released by pulling the handle of the sealing material (400), which is connected to the lower flange surface (210) of the container lid (200) and the upper flange surface (130) of the lid body (100) in a detachable manner between the lower flange surface (210) of the container lid (200) and the upper flange surface (130) of the lid body (100) with one hand while holding the handle of the sealing material (400) which is detachably connected between the lower flange surface (210) of the container lid (200) and the upper flange surface (130) of the lid body (100), in a horizontal direction on the other side, so that the lower end of the sealing material (400) is detached from the upper flange surface (130) of the lid body (100).

[0042] Meanwhile, if the user does not cut the sealing material (400) to open the opening / closing lid (200) while the connecting web (700) formed on the lower surface of the sealing material (400) is not properly connected due to a defect occurring on the upper flange surface (130) of the lid body (100), the opening / closing lid (200) is prevented from opening by maintaining a sealed state so that the opening / closing lid (200) is not opened by means of an auxiliary sealing means (500) in which a catch projection (510) formed protruding from one side of the lower outer surface of the opening / closing lid (200) engages with a catch groove (520) cut to a certain size on one side of the sealing material (400).

[0043] Meanwhile, the lower surface of the sealing material (400) is connected to the upper flange surface (130) of the lid body (100) through a plurality of connecting webs (700) formed at the lower surface.

[0044] Accordingly, it can be seen that when the sealing material (400) according to the present invention is cut off due to unsealing, the connecting web (700) on the bottom surface is cut off from the lower flange surface (210) of the opening / closing lid (200) and the upper flange surface (130) of the lid body (100) to achieve unsealing.

[0045] In addition, as described above, as the sealing material (400) is removed from the lid body (100) due to the release of the seal of the opening / closing lid (200), the auxiliary sealing means, which is a secondary sealing structure, is also released due to the removal of the sealing material (400).

[0046] That is, it can be seen that the sealing material (400) releases the first and second sealing structures with a single cut.

[0047] In the configuration described above, the auxiliary sealing means, which is a secondary sealing structure, is composed of a locking groove (520) cut and formed to a certain size on one side of the sealing material (400) and a locking projection (510) formed in a shape related to the locking groove (520) on one side of the lower outer surface of the opening / closing lid (200) and held in place by being caught in the locking groove (520) through the inner surface of the sealing material (400).

[0048] As described above, in the auxiliary sealing means, which is a secondary sealing structure, when the sealing material (400) is not cut and the cutting surface (800) of the upper and lower end surfaces and the connecting web (700) are respectively connected to the lower flange surface (210) of the opening / closing lid (200) and the upper flange surface (130) of the lid body (100), the locking projection (510) formed on the outer surface of the opening / closing lid (200) is held in place by being caught on the locking groove (520) formed on the lower surface of the sealing material (400) through the inner surface of the sealing material (400).

[0049] Accordingly, as previously described, the aforementioned auxiliary sealing means prevents the opening of the opening / closing lid (200) even if a defect occurs in the cutting surface (800) between the upper surface of the sealing material (400) and the lower flange surface (210) of the opening / closing lid (200) while the sealing material (400) is not being cut, because the locking projection (510) on the opening / closing lid (200) side is caught on the locking groove (520) on the lower surface of the sealing material (400).

[0050] Of course, when the sealing material (400) is cut and removed from the container lid (10) in accordance with the seal release, the locking projection (510) on the opening / closing lid (200) side and the locking groove (520) on the bottom surface of the sealing material (400) are released, so the second sealing structure is also released at the same time as the first sealing structure is released.

[0051] Meanwhile, if you want to separate the container lid (10) from the food container and discharge it, you pull the opening / closing lid (200) while holding it with your hand, and the load is transferred to the lid body (100) by the connecting material (300) connecting the lid body (100) and the opening / closing lid, and the lid body (100) is torn apart around the cut groove (610) by the load transferred to the lid body (100) and separated from the spout of the food container.

[0052] As a result, even women or elderly people with weak strength can conveniently separate and discharge the container lid (10) from the food container without any separate work or the use of tools.

[0053] The embodiments described above should be understood as exemplary in all respects and not limiting.

[0054] In addition, the scope of protection of the present invention is determined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the claims and equivalent concepts thereof should be interpreted as being included within the technical scope of the present invention.
