Description

Cap for liquid product container and liquid product container including same

[0001] The present invention relates to a cap installed in a container containing a liquid product and a liquid product container including the same.

[0002]

[0003] In general, a container used to store liquid products such as sesame oil, cooking oil, soy sauce, and oil is equipped with a cap at the entrance to facilitate the discharge of the liquid inside the container for use.

[0004] These caps are equipped with a discharge port through which liquid inside the container is discharged, and a discharge tube extending long from the discharge port.

[0005] When the existing cap discharges and stops the liquid inside the container, the flow of the discharged liquid is not properly stopped, so some of the liquid falls and gets stuck on the wall of the container, or the liquid goes down the discharge pipe and gets stuck on the wall of the container. This phenomenon is called leakage.

[0006] To prevent this, a technology is disclosed that solves the problem by providing a wall extending upward on the outer surface of the cap so that liquid that falls from the discharge port or flows down the discharge port accumulates on the inside of the wall.

[0007] However, in these cases, the above-mentioned problem does not occur in the early stages of use, but as the number of times the container is used increases, the accumulated liquid passes over the wall, runs along the outer surface of the cap, and gets on the outer wall of the container, causing leakage.

[0008] Patent documents 1 to 5 disclose caps for various liquid products, which partially solve the problem of leakage by improving the structure of the cap and exhibit the effect of recovering excess liquid generated during use.

[0009] However, when these caps are actually used, it can be seen that leakage still occurs, although the frequency is less than before. This is thought to be because, in order to properly obtain the effects mentioned in the patent literature, factors such as the size, length, arrangement, and distance between each component must be considered in order to achieve the effects of improved cap structure, but this consideration has not been made.

[0015] (Patent Document 5) KR 1994-017803 U

[0016]

[0017] Accordingly, the present invention has been devised to solve the above-mentioned conventional problems, and to provide a cap for a liquid product container that effectively prevents leakage by improving the structure of a cap provided on a liquid product container, and a liquid product container including the same.

[0018]

[0019] In order to achieve the above object, the present invention provides a cap installed in a container containing a liquid product, the cap comprising: a bottom portion formed to be inclined downward from one side to the other side, the bottom portion having a discharge port communicating with the upper portion of the container; an outer wall extending upward from a peripheral side of the bottom portion; a discharge pipe extending upwardly higher than the outer wall from a peripheral side of the discharge port while being spaced apart from the outer wall; an undercut extending from an upper portion of the peripheral side of the outer wall toward the discharge pipe; a cut portion in which the other side of the discharge port is located in the cut portion; A cap for a liquid product container is provided, wherein the upper portion of the discharge tube includes a slit extending downward, the distance between the slit and the upper portion of the outer wall is 7.5 mm or more and 10 mm or less, the distance between the slit and the central axis of the discharge tube is 8 mm or more and 9 mm or less, the angle at which the bottom portion is inclined is 10° or more and 12° or less, and the length by which the undercut extends is 0.5 mm or more and 0.7 mm or less.

[0020] It further includes a closing film positioned to block the discharge port; a connecting portion connected to the other side of the closing film and extending upward along the length of the discharge pipe; and a cutting ring positioned spaced apart from the outer side of the upper circumference of the discharge pipe and having a diameter larger than that of the discharge pipe; and it is preferable that the diameter of the cutting ring is 22 mm or more and 24 mm or less.

[0021] It is preferable that a portion of the liquid discharged through the discharge pipe through the discharge port falls to one side of the bottom surface between the outer wall and the lower part of the discharge pipe, and the remaining portion descends along the slope along the outer side of the discharge pipe, flows to one side of the bottom portion, flows along the slope to the other side of the bottom portion, and flows into the other side of the discharge port.

[0022] In addition, a liquid product container is provided, including the cap and a container on which the cap is installed.

[0023]

[0024] According to the cap for a liquid product container according to the present invention and the liquid product container including the same, the following effects can be obtained.

[0025] 1) By improving the structure of each component forming the cap, it is possible to obtain the effects of preventing the liquid from flowing out of the container, causing the liquid to fall to the bottom, causing the liquid that has flowed to the bottom to be recovered into the container through the discharge port, and preventing the liquid that has descended to the bottom from overflowing outside the outer wall.

[0026] 2) In addition, the above effect can be maximized by optimizing the size, length, arrangement of each component and the distance between each component.

[0027] 3) In addition, it has the advantage of being easy to manufacture a cap while satisfying the above effects.

[0035] The above-described purposes, features, and other advantages of the present invention will become more apparent by describing preferred embodiments of the present invention in detail with reference to the accompanying drawings. In this process, the thickness of lines and the sizes of components depicted in the drawings may be exaggerated for clarity and convenience. Furthermore, the terms described below are defined based on their functions in the present invention and may vary depending on the intentions or practices of the user or operator. Therefore, the definitions of these terms should be based on the contents throughout this specification.

[0036] In addition, the described embodiments are provided as examples for the purpose of explaining the invention and do not limit the technical scope of the present invention.

[0037]

[0038] Hereinafter, a cap (100) for a liquid product container according to one embodiment of the present invention will be described in detail with reference to the attached drawings 1 to 5.

[0039] A cap (100) for a liquid product container according to one embodiment of the present invention is installed on the upper part of the container (10).

[0040] An insertion portion is positioned at the bottom of the cap (100) to be inserted and installed at the top of the container (10), and a catch may be formed on the outer circumference of the insertion portion so that the cap (100) can be inserted and fixed in the container (10), and a side portion is positioned on the circumference of the insertion portion.

[0041] The drawing shows a cap (100) installed on the top of a container (10). The shape or material of the container (10) on which the cap (100) is installed is not limited, and may be a shape capable of accommodating a fluid product that can flow, such as a liquid, a solid-liquid mixture, or a bottle, can, or pack, and may be made of glass, metal, plastic, or various other materials.

[0042] A liquid product, i.e. a product made of liquid, is stored inside the container (10), and when the container (10) is tilted to one side, the liquid inside the container (10) is discharged to the outside through the cap (100) and used.

[0043] Hereinafter, as shown in FIGS. 1 to 4, the direction in which the cap (100) is installed in the container (10), i.e., the direction in which the container (10) tilts when discharging liquid, is referred to as one side, and the opposite side as the other side.

[0044] A cap (100) for a liquid product container according to one embodiment of the present invention includes a bottom portion (110), an outer wall (120), and a discharge pipe (130).

[0045] The bottom part (110) is located on one side of the upper part of the container (10). Specifically, the bottom part (110) may be located on the upper part of the insertion part.

[0046] Near the center of the bottom part (110), a discharge port (111) is formed that is opened longitudinally from one side to the other side, so that the bottom part (110) is connected to the upper side of the container (10).

[0047] By tilting the container (10) to one side, the liquid inside the container (10) is discharged through the discharge port (111).

[0048] The bottom part (110) is positioned in a slanted shape from one side toward the other side downward.

[0049] In this way, the liquid that falls during or after discharge can flow from one side of the bottom (110) to the other side.

[0050] The outer wall (120) is positioned so as to extend upward from the circumference of the bottom portion (110). By positioning the outer wall (120), liquid that falls during or after discharge is prevented from flowing toward the side portion and reaching the outside of the container (10) by being collected on the inside of the outer wall (120).

[0051] An undercut (121) is located on the upper part of the outer wall (120). The undercut (121) extends from the upper part of the circumference of the outer wall (120) toward the inner side, that is, toward the discharge pipe (130).

[0052] The discharge pipe (130) is positioned at a predetermined distance from the bottom (110) to the inside of the outer wall (120). The discharge pipe (130) extends upward from the bottom (110) to surround the discharge port (111), and its height is higher than the height of the outer wall (120).

[0053] Accordingly, when the container (10) is tilted to one side, the liquid inside the container (10) is discharged to the outside through the discharge port (111) and the discharge pipe (130).

[0054] A cut portion (131) is located on the other side of the discharge tube (130). The cut portion (131) is formed by cutting a portion of the other side of the circumference of the discharge tube (130) upward toward the bottom (110), and a portion of the other side of the discharge port (111) is located on the inside of the cut portion (131).

[0055] A slit (132) is positioned at the upper part of the discharge pipe (130). The slit (132) is positioned so that the upper part of the discharge pipe (130) forms a curved surface and extends downward.

[0056] Since the slit (132) is positioned at the top of the discharge pipe (130), when the container (10) is tilted to the other side while the liquid is being discharged, the liquid being discharged by the slit (132) is cut off.

[0057] The closing film (140) is positioned to block the open discharge port (111). The closing film (140) is formed to have the same shape as the discharge port (111) when the cap (100) is manufactured, and is configured to block the discharge port (111).

[0058] The outer side of the closure film (140) and the inner side of the discharge port (111) are connected. That is, the closure film (140) forms a part of the bottom part (110) while blocking the discharge port (111).

[0059] Since a groove (141) is formed at the part where the closing membrane (140) and the outlet (111) are connected, the thickness of the connecting portion (132) is thinner than that of the bottom portion (110).

[0060] A connecting portion (132) is located on the other side of the closure film (140). That is, the connecting portion (132) is connected to the cut portion (131) of the discharge pipe (130) and extends upward along the length of the discharge pipe (130).

[0061] The cutting ring (143) is positioned in a ring shape surrounding the discharge pipe (130), and its inner side is positioned apart from the outer side of the discharge pipe (130).

[0062] The other side of the cutting ring (143) is connected to the upper part of the connecting part (132). That is, the other side of the cutting ring (143) and the other side of the closing membrane (140) are connected through the connecting part (132).

[0063] As shown in Fig. 1, when the closing film (140) is blocking the discharge port (111), when the user grabs and pulls the cutting ring (143) by hand when using the container (10) for the first time, the closing film (140) connected to the connecting portion (132) is also pulled, and the groove (141) is ruptured, so that the closing film (140) is removed from the discharge port (111), and the discharge port (111) is opened, resulting in a state as shown in Fig. 3.

[0064] Next, referring again to FIGS. 1 to 4, the operation of a cap (100) for a liquid product container according to one embodiment of the present invention will be described.

[0065] First, as described above, when using the container (10) for the first time, the closing film (140) is removed by pulling the cutting ring (143). After the closing film (140) is removed, the container can be used continuously with the discharge port (111) open.

[0066] When the container (10) is tilted to one side, the liquid contained inside the container (10) is discharged to the outside through the discharge port (111) and the discharge pipe (130).

[0067] When the amount of liquid discharged is the amount used, the container (10) is tilted to the other side. At this time, the flow of liquid discharged through the discharge pipe (130) is cut off by the slit (132) and flows back into the container (10) through the discharge port (111).

[0068] By stopping the flow of liquid discharged through the discharge pipe (130), some of the liquid is prevented from being deposited on the outer surface of the container (10) when the discharge of the liquid stops.

[0069] At this time, some of the liquid in the upper part of the discharge pipe (130) falls between the outer wall (120) on one side of the bottom part (110) and the discharge pipe (130).

[0070] In addition, the slit (132) is extended to the outer lower part of the discharge port (111), so that the remaining liquid that was stuck in the slit (132) flows along the outer wall (120) of the discharge pipe (130) along the slit (132) and descends between the outer wall (120) on one side of the bottom (110) and the discharge pipe (130).

[0071] At this time, if the amount of liquid descending to the bottom (110) along the outer wall (120) of the discharge pipe (130) is large, it may overflow beyond the outer wall (120), but this overflow phenomenon is prevented by the undercut (121) located on the inner side of the outer wall (120).

[0072] The liquid that has descended to one side of the bottom (110) flows to the other side along the slope of the bottom (110), passes through the cut (131), and is recovered back into the container (10) through the discharge port (111).

[0073] By using the cap (100) for a liquid container according to the present invention, when the liquid contained in the container (10) is used, excess liquid is allowed to fall to the bottom (110), thereby preventing the phenomenon of the liquid seeping out of the container (10) and flowing.

[0074] In addition, the phenomenon of liquid descending to the bottom (110) overflowing outside the outer wall (120) is prevented, and excess liquid can be recovered into the container (10) through the discharge port (111).

[0075] However, in order to maximize the above-mentioned effect, the size, arrangement, and distance between each component are important.

[0076] The effect of preventing the liquid from flowing out of the container (10) is mainly related to the height of the sled (132), and the effect of causing the liquid to fall to the bottom (110) is related to the position of the sled (132).

[0077] And, the effect of allowing the liquid flowing to the bottom (110) to be recovered into the container (10) through the discharge port (111) is related to the angle of the slope of the bottom (110), and the effect of preventing the liquid descending to the bottom (110) from overflowing outside the outer wall (120) is related to the length of the undercut (121).

[0078] As factors related to the above-mentioned effect, the distance between the upper part of the sled (132) and the upper part of the outer wall (120) was set as a, the distance between the sled (132) and the central axis of the discharge pipe (130) was set as b, the angle at which the bottom part (110) is inclined was set as c, and the extended length of the undercut (121) was set as d.

[0079] And, the effect of preventing the liquid from flowing out of the container (10) is A, the effect of causing the liquid to fall to the bottom (110) is B, the effect of causing the liquid that has flowed to the bottom (110) to be recovered into the container (10) through the discharge port (111) is C, and the effect of preventing the liquid that has descended to the bottom (110) from overflowing out of the outer wall (120) is D. By changing the above factors, the above effects were confirmed and shown in Table 1 as follows.

[0080] In Table 1, the effect according to the factor is expressed as a score, with 0 indicating no effect and 10 indicating maximum effect.

[0081]

[0082] Number Factor Effect (Score) 1a (mm) b (mm) c (°) d (mm) ABCD 2 6 12. 5000000 3 6 12. 5000000 4 6 12. 5000000 5 6 12. 5000000 6 6 12. 500000 17 10 12. 500 1000 18 6 10. 5000 100 9 6 8. 500 57 0 5 10 6 12. 500.5000811612.501000012108.560.5107031388.560.510100314106.7560.51075515108.5611010031688.560.51010121788.580.51010651888.5100.510101010

[0083] As shown in Table 1, when all factors are comprehensively considered, it can be seen that the result marked with an underline, number 18, is the most effective. Specifically, when the distance (a) between the upper part of the sled (132) and the upper part of the outer wall (120) is 6 mm, it is impossible to obtain the effect (A) of preventing the liquid from flowing out of the container (10), and it can be seen that it is effective from about 8 mm. However, if the distance (a) between the upper part of the sled (132) and the upper part of the outer wall (120) becomes longer, the overall height of the cap (100) becomes unnecessarily high, making it difficult to use. Therefore, it can be said that it is effective to set the distance (a) between the upper part of the sled (132) and the upper part of the outer wall (120) to be 7.5 mm or more and 10 mm or less.

[0084] If the distance (b) between the central axes of the sled (132) and the discharge pipe (130) exceeds 10.5 m and becomes 12.5 mm, that is, if the diameter of the sled (132) becomes too large, the effect (B) of causing the liquid to fall to the bottom (110) cannot be obtained, and the liquid falls to the outside instead of falling to the bottom (110). In addition, if the distance (b) between the central axes of the discharge pipe (130) is 6.75 mm, injection manufacturing is impossible, and furthermore, the diameter of the discharge pipe (130) becomes small, so that the amount of liquid discharged is reduced to a level that is difficult to use.

[0085] Therefore, it can be said that the distance (b) between the center axis of the sled (132) and the discharge pipe (130) is effective to be 8 mm or more and 9 mm or less.

[0086] If the angle (c) at which the bottom part (110) is inclined is 6° or 8°, the liquid on one side of the bottom part (110) does not flow to the other side of the bottom part (110) where the discharge port (111) is located, and thus the effect (C) of allowing the liquid that has flowed to the bottom part (110) to be recovered into the container (10) through the discharge port (111) cannot be obtained, and it can be seen that this is effective at 10°. In addition, if the angle (c) at which the bottom part (110) is inclined exceeds 12°, the lower part of the slope of the bottom part (110) becomes close to the part where the cap (100) and the bottom container (10) are joined, and thus an assembly defect may occur when the cap (100) and the container (100) are joined. Therefore, it is effective that the angle (c) at which the bottom part (110) is inclined is 10° or more and 12° or less.

[0087] If there is no undercut (121), that is, if the extended length (d) of the undercut (121) is O mm, it is impossible to obtain the effect (D) of preventing the liquid descending to the bottom (110) from overflowing outside the outer wall (120), and it is effective from 0.5 mm.

[0088] However, if the extended length (d) of the undercut (121) exceeds 0.7 mm, defects may occur during the injection production of the cap (100), making it difficult to apply. Therefore, it can be said that it is effective for the extended length (d) of the undercut (121) to be 0.5 mm or more and 0.5 mm or less.

[0089] The diameter of the cutting ring (143) is e, and the cutting ring (143) itself is not directly related to the above-mentioned effect, but the diameter (e) of the cutting ring (143) that satisfies all of the above-mentioned factors of each configuration for obtaining such an effect is 22 mm or more and 24 mm or less, and when the diameter (e) of the cutting ring (143) is configured in this way, it was confirmed that all of the above-mentioned effects can be obtained, while injection-molding is easy and also it is easy to pull the cutting ring (143) to cut the closure film (140).

[0090]

[0091] By installing and using the cap for a liquid product container according to the present invention described above on a liquid product container, the following effects can be obtained.

[0092] 1) By improving the structure of each component forming the cap, it is possible to obtain the effects of preventing the liquid from flowing out of the container, causing the liquid to fall to the bottom, causing the liquid that has flowed to the bottom to be recovered into the container through the discharge port, and preventing the liquid that has descended to the bottom from overflowing outside the outer wall.

[0093] 2) In addition, the above effect can be maximized by optimizing the size, length, arrangement of each component and the distance between each component.

[0094] 3) In addition, it has the advantage of being easy to manufacture a cap while satisfying the above effects.

[0095]

[0096] While preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. That is, those skilled in the art will appreciate that numerous modifications and variations to the present invention can be made without departing from the spirit and scope of the appended claims, and all such appropriate modifications and equivalents should be considered within the scope of the present invention.
