Description

Technology Field

[0001] The present invention relates to a functional oil container, and more specifically, to a functional oil container capable of safely storing various types of oil without rancidity and enhancing convenience of use. Background Technology

[0002] Generally, perilla oil refers to oil extracted by pressing perilla seeds and processed to be suitable for consumption. Perilla oil is a vegetable oil with a high degree of unsaturation and has been widely used in Korea for its unique aroma. Furthermore, the highly unsaturated essential fatty acids contained in perilla oil transport cholesterol within the human body, effectively preventing adult diseases such as arteriosclerosis and hypertension, and are therefore favored as a health food.

[0003] However, due to the unstable chemical properties of unsaturated fatty acids, perilla oil is prone to rancidity (a phenomenon in which oils undergo chemical changes due to the action of oxygen in the air), which leads to a decline in shelf life. In fact, perilla oil has long been known to undergo rancidity over time, causing its taste and aroma to deteriorate. In addition, edible oils such as canola oil, soybean oil, and olive oil also have high rancidity rates when stored in containers or used for extended periods, which has an adverse effect on their edibility.

[0004] In order to prevent rancidity of sesame oil, cooking oil, etc., the industry has long been improving the lids of oil containers or presenting technologies that prevent the cooking oil inside the container from coming into contact with oxygen, such as Korean Registered Patent No. 10-1251770 and Korean Published Patent No. 10-2010-0117863, and countless rancidity-preventing containers are being introduced.

[0005] While the oil container of this prior art is effective in significantly reducing the rancidity rate of oil, it is pointed out that various types of edible oils, including sesame oil and perilla oil contained within the container, have viscosity, making it very difficult to drain and consume all the oil remaining at the bottom of the container. Furthermore, to resolve this, the container must be inverted so that the oil reaches near the lid before draining it, making the oil draining process very cumbersome. It is also pointed out that failing to perform this draining process results in economic losses due to oil loss.

[0006] Of course, in addition to the edible oil mentioned above, honey, dressing sauces, seasoning sauces, or liquid cosmetics may also present the same problems.

[0007] In addition, since the containers presented above cannot be reused and are disposed of, environmental pollution issues are raised. Therefore, it is desirable that the oil container presented above allows the inside of the container to be cleaned and the oil contained inside to be used without leaving any residue. Furthermore, there was a demand for a container that prevents the oil contained in the container from becoming rancid during long-term storage. The applicant has filed a patent application for an oil container regarding this technology under Korean Intellectual Property Office Registration No. 10-1957038 and has been registered.

[0008] However, this time, by further improving the technology previously registered, we have come to propose a more compact and efficient functional oil container. Prior art literature

[0031] Referring to these drawings, a functional oil container (100) according to one embodiment of the present invention can safely store various types of oil without rancidity and also enhance convenience of use. Here, various types of oil may include edible oils such as perilla oil, sesame oil, canola oil, soybean oil, and olive oil, but may also store other oils. Therefore, the scope of rights of the present invention is not limited to these matters.

[0032] A functional oil container (100) according to one embodiment of the present invention capable of providing such effects may include a container body (110), a screw shaft (120), a shaft supporter (130), a rotary knob (140), a piston unit (150), a donut plate (160), a container cover (170), an upper cover module (180), and a container stopper (190).

[0033] The container body (110) has the shape of a cylindrical pipe with both ends open and forms a place in which oil can be refilled.

[0034] The container body (110) is made of a transparent or translucent plastic material that allows internal observation so that the oil filled inside can be seen. Of course, the container body (110) does not necessarily have to be made of a transparent or translucent plastic material, but it can be effective if it is made of a transparent or translucent plastic material.

[0035] The screw shaft (120) is rotatably positioned along the longitudinal direction of the container body (110) in the center area within the container body (110).

[0036] Screw threads are formed on the outer surface of the screw shaft (120). A disc-shaped shaft flange (121) is attached to the lower portion of the screw shaft (120). The shaft flange (121) of the screw shaft (120) can be supported by the flange support rib (132) of the shaft supporter (130).

[0037] The shaft supporter (130) is coupled to a lower portion of the container body (110) and is a means for rotatably supporting the screw shaft (120) at that position.

[0038] A shaft passage hole (131) through which a screw shaft (120) passes is formed in the central region of the shaft supporter (130). The screw shaft (120) passes through the shaft passage hole (131), and its lower end is positioned on a rotary knob (140).

[0039] A flange support rib (132) is provided around the shaft passage hole (131) to support the shaft flange (121) of the screw shaft (120). The screw shaft (120) is inserted up to the position where the shaft flange (121) is supported by the flange support rib (132). Accordingly, the shaft flange (121) also serves as a stopper that limits the insertion depth of the screw shaft (120).

The shaft connecting pin (122) is a means for connecting the screw shaft (120) to the rotary knob (140) and the screw shaft (120) to integrally connect the screw shaft (120) to the rotary knob (140).

[0042] In the central region of the rotary knob (140), a shaft support pin coupling portion (141) is formed to support the end of the screw shaft (120) while the shaft connecting pin (122) is pin-coupled.

[0043] When the rotary knob (140) is turned clockwise, for example, the piston unit (150) moves up as shown in FIG. 16 and oil is discharged. Then, when the rotary knob (140) is turned counterclockwise, for example, the piston unit (150) moves down as shown in FIG. 13.

[0044] The piston unit (150) is rotatably coupled to the screw shaft (120) in the upper region of the shaft supporter (130) and moves linearly on the screw shaft (120) according to the rotational operation of the rotary knob (140) and serves to push oil in the container body (110) to the upper region of the container body (110).

[0045] This piston unit (150) comprises a piston body (151), a plurality of sealing rings (152) that are fitted into a plurality of body slots (151a) formed on the outer wall of the piston body (151) to maintain a seal between the piston body (151) and the container body (110), a screw nut (153) whose outer surface is coupled to a body groove (151b) formed in the central region of the piston body (151) and whose inner surface is screw-coupled to a screw shaft (120), and which moves the piston body (151) by moving linearly on the screw shaft (120) according to the rotational movement of a rotary knob (140), a piston guide (154) which is positioned above the screw nut (153) and through which the screw shaft (120) passes, and which guides the movement of the piston body (151), and a screw nut (153) and a piston that is coupled to the body groove (151b) of the piston body (151). It may include a fixing washer (155) that fixes the guide (154). As illustrated, the inner surface of the screw nut (153) has threads, but the inner surface of the piston guide (154) does not have threads.

[0046] The donut plate (160) is a coin-shaped structure placed in the upper portion of the container body (110) and has a shaft passage (161) through which the screw shaft (120) passes.

[0047] The container cover (170) is positioned in the upper region of the donut plate (160) and is supported by the upper end of the screw shaft (120) and has a cone-shaped protruding support (171) that rises in a cone shape. The upper end of the screw shaft (120) is positioned within the cone-shaped protruding support (171).

[0048] The upper cover module (180) is a structure that is positioned on the upper part of the container cover (170) and is provided with a first boss portion (181) on which a conical protruding support portion (171) is positioned, and is screw-coupled to the upper part of the container body (110). A discharge hole is formed in the center of the first boss portion (181) so that oil can be discharged.

[0049] The container stopper (190) has a second boss portion (191) that is screw-coupled to the first boss portion (181) of the top cover module (180) in the upper region of the top cover module (180).

[0050] The operation of a functional oil container (100) having such a configuration is explained.

[0051] In a state like that of Fig. 1, the oil inside the container body (110) can be stored without rancidity. Then, when the container stopper (190) is opened and the rotary knob (140) is turned, for example, clockwise, the piston unit (150) moves up as shown in Fig. 16, and the oil is pushed toward the cone-shaped protruding support (171) of the container cover (170) and then discharged through the opening formed at the end of the cone-shaped protruding support (171).

[0052] And, when the rotary knob (140) is turned counterclockwise, for example, the piston unit (150) moves down as in Fig. 13.

[0053] According to the present embodiment, which operates based on the structure described above, various types of oil can be safely stored without rancidity, and convenience of use can be enhanced.

[0054] As such, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be deemed to fall within the scope of the claims of the present invention. Explanation of the symbols
