Description

Liquid container with ventilation means}

The present invention relates to a liquid container used to store various liquids such as water, oil, and liquid products, and more specifically, to a liquid container having a ventilation means to allow air to flow into the container when discharging the contents. It's about the dragon horse barrel.

In general, as one of the containers for storing liquid contents such as water or oil, a blow molded container called a maltong is mainly used.

A barrel is a storage container that can hold a volume equivalent to one horse (approximately 18 to 20 liters) of grain or liquid. There is a device at the top of the container that allows the container to be tilted when transporting or discharging the contents. A handle is formed to allow

In particular, among the barrels, the liquid container, which stores food such as water or soy sauce, and liquids such as kerosene, has a problem in that it generates a severe gurgling sound when the passage is blocked when discharging the contents, and it does not pour cleanly into the target area, so it is not poured into the funnel. There were inconveniences such as using .

Also, when discharging the liquid, it cannot be discharged quickly because of the gurgling noise, it is very difficult to discharge it while the user is holding it and standing, and there is a problem in that the flow path is completely blocked due to the tilt of the container, so the liquid flows into the outlet. Various methods have been proposed to allow liquid to be discharged quickly using the principle that air is sucked into the container when discharged.

For example, in Korea Registered Utility Model No. 20-0122554 (May 12, 1998), the inner passage of the handle is communicated with the inside of the container, and a socket is provided that is fitted and connected to the liquid outlet to ensure ventilation.

However, such a structure cannot be commercialized because it is very difficult to manufacture due to the nature of the liquid storage container produced by the blower method, or even if commercialized, productivity is extremely low, making it very difficult to commercialize.

As another example, in Registered Utility Model No. 20-040748 (June 27, 2016), a structure was disclosed that allows the contents to be discharged smoothly by providing a ventilation member that allows air to flow from the outside into the container when the contents are discharged from the inner diameter of the injection port. .

However, this structure of installing a separate ventilation member has low productivity and requires a separate assembly process, which reduces manufacturing efficiency, making it difficult to commercialize.

Another example is Registered Utility Model No. 20-0468258 (July 26, 2013), which has a structure with a separate middle stopper. When the contents are to be discharged, the ventilation passage of the middle stopper is opened to allow air intake into the container. Malt containers that can quickly drain liquid are widespread.

However, this intermediate stopper also requires significant changes to the existing design, and because the valve to be assembled to the middle stopper must be manufactured separately and then assembled, there is a problem of reduced productivity and price competitiveness.

In addition, the method of using the middle stopper is to use it by pulling the valve and then completely opening it after discharging more than a certain amount of contents. Not only are users unfamiliar with how to use this, but it is also difficult to use the flow path that can be secured for air intake. Because the size is too small, it will not be discharged smoothly unless it is completely opened from the beginning.

Also, when opening the container from the beginning and using it, if the tilt of the container is not properly adjusted, the full contents will flow through the middle stopper, and there is a high risk of the contents leaking. In particular, due to the position of the middle stopper, it will overflow even if the container is tilted slightly, so it is tilted. Control is very important and causes inconvenience during use.

The present invention is intended to solve the above problems, and maintains the structure of the existing liquid storage bottle, while having a structure that allows air intake when discharging the liquid contents without changing the production process, as well as external The structure for sucking in air makes it very easy to use, and a sufficient flow path for air to be sucked in is secured to ensure smooth discharge.

The present invention as a technical idea for achieving the above object is to have a handle for transportation at the top of the container body for storing the contents and a neck portion having an opening hole formed in the cylindrical portion for injecting and discharging the contents, and the neck portion is formed. Centering around the handle, a first neck portion is disposed on one side and a second neck portion on the other side, and spiral fastening portions are formed in the first and second neck portions, respectively, in the first neck portion and the second neck portion. In the bottle for storing liquid, the stopper is mounted in a spiral structure to seal it, and the user can selectively open the stopper mounted on the first and second neck parts to inject or discharge the contents, wherein the first neck part And the second neck portion is formed so that the flow path size varies so that one side of the opening hole diameter of the cylindrical portion is relatively small and the other side is relatively large, and the neck portion on the side where the opening hole diameter is formed relatively large is a spiral formed on the outer periphery of the cylindrical portion. An intake portion composed of a concavo-convex pattern is formed at the fastening portion, and the intake portion forms a ventilation passage of an internal shape such that the spiral fastening portion has a vertically cut structure among the outer peripheral portion of the cylindrical portion where the spiral fastening portion is formed, and the stopper is a stopper. Depending on the degree of tightening, a protruding rim is formed on the inner surface of the cover to block or open the ventilation passage by contacting the top of the cylindrical part of the neck to completely seal or control the amount of air intake flowing into the container body. To prevent gurgling when discharging the contained contents, the stopper is used as a valve to control the amount of air intake.

According to the liquid container having a ventilation means of the present invention, when discharging the liquid, the inside of the container communicates with the outside air to suck in the outside air, preventing the liquid from being rapidly discharged and gurgling due to the pressure difference between the inside and the outside. , Liquid is discharged smoothly and stable discharge is possible.

In addition, the existing malt barrel structure, which has a double stopper structure, is maintained as is,

Because it can be manufactured while maintaining existing production facilities without changing the existing manufacturing process, it is very economical and can provide high-quality products at a low cost.

In addition, when discharging the contents, the container body is tilted and the passage through which air is sucked is located at the top, so the contents do not overflow or flow, making it possible to use it cleanly. The amount of air intake can be adjusted by locking or unlocking the injection cap. It is very convenient to use because it is intuitive.

In addition, airtightness can be secured by applying appropriate tension when closing the stopper, and the sealing effect is improved while minimizing deformation of the stopper even when used repeatedly, providing a product with improved durability.

Also, if you separate the stopper and use it as a replacement for the ready-made maltong stopper, the amount of air intake can be adjusted, making it possible to use it in a variety of ways.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

The liquid storage container of the present invention is equipped with a ventilation means to prevent splashing and ensure stable discharge when discharging the contents. The container body 100 includes a handle 120, a first neck portion 140a, and a first neck portion 140a. A neck portion 140 including a second neck portion 140b is provided, and a stopper 200 is mounted on the first neck part 140a and the second neck part 140b, respectively, and the stopper 200 is attached to the neck part. By forming a ventilation means in the structure mounted on (140), air is communicated into the container body when discharging the contents in the container body, allowing the contents to be discharged stably.

First, as shown in Figure 2, the container body 100 is manufactured by blow molding into a hollow structure to accommodate the contents, and a handle 120 is provided at the top of the container body 100 for transportation, etc. The container body 100 may further include an auxiliary handle 140a at the bottom of the container body 100 for discharging the contents.

And at the top of the container body 100, a neck portion 140 is formed with an opening hole 144 in the cylindrical portion 142 for injection and discharge of contents. The neck portion 140 has a handle 120. It consists of a first neck portion (140a) formed on one side centered on the handle 120, and a second neck portion (140b) formed on the other side centered on the handle 120, and is provided at both ends of the upper end of the container body 100. 140a) and the second neck portion 140b are arranged respectively, so that the neck portion is double arranged.

In addition, a spiral fastening portion 146 is formed on the first and second neck portions 140a and 140b, so that the stopper 200 is mounted in a spiral structure on the first neck portion and the second neck portion, respectively, to achieve sealing, The user can selectively open the stopper 200 mounted on the first and second neck parts to inject or discharge the contents.

In the present invention, the first neck portion 140a is used as a discharge port with a relatively small opening hole diameter, and the second neck portion 140b is used as an injection port with a relatively large opening hole diameter.

However, the sizes and uses of the first neck portion 140a and the second neck portion 140b may be reversed, so their uses are not limited. Depending on the user's choice or need, the first neck portion 140a may be used to inject content or It can be used for discharge, or the second neck portion 140b can be used for injection or discharge of contents.

That is, since the first and second neck portions 140a and 140b are disposed on one side and the other side of the container body 100, respectively, a double opening hole 144 is formed to enable discharge or injection, and each opening hole A stopper is coupled to (144), and the neck part on either side of the two neck parts allows air intake through the ventilation passage unless it is completely sealed even when the stopper is installed, so that when discharging the contents contained in the horse barrel. As air is sucked in smoothly, the contents can be discharged stably.

More preferably, among the two opening holes 144, the opening hole formed with a relatively large diameter is used as an inlet for containing the contents, and on the contrary, the opening hole formed with a small diameter is used as an outlet for discharging the contents. will be.

At this time, in addition to the stopper 200, a discharge stopper 300 made of a flexible hose may be installed in the opening hole 144 of the first neck part 140a, which is relatively small among the neck parts 140. A stopper 200 fastened in a spiral structure is installed in the opening hole 144 of the second diameter neck portion 140b, and the ventilation means can be communicated or blocked by opening and closing the stopper 200.

At this time, as the stopper 200 is opened and closed, the ventilation means that allows external air to be sucked into the container body is communicated or blocked. As shown in FIG. 3, an intake portion 160 is formed in the neck portion 140. Forms a ventilation channel.

The intake portion 160 is formed in a concavo-convex pattern on the spiral fastening portion 146 formed on the outer periphery of the cylindrical portion 142 of the second neck portion 140b where the opening hole is formed to be relatively large in diameter, thereby forming a ventilation passage. , in a preferred embodiment of the intake unit 160, the ventilation passage 162 may be formed in the outer peripheral portion of the cylindrical part where the spiral fastening part 146 is formed, so that the spiral fastening part has a vertically cut structure.

In addition, the intake portion 160 can be completely sealed or opened depending on the degree of tightness of the stopper 200 coupled to the neck portion 140, and the container can be opened by adjusting the degree of opening. When discharging the contents inside the main body 100 to the outside, the amount of air intake flowing into the container body can be adjusted to prevent gurgling when discharging the contents.

At this time, the cover part 240 is composed of a wall 220 on which the spiral fastening part 222 is formed and a cover part 240 at the top, and a neck part 140 is formed on the inner surface, that is, the lower surface, of the cover part 240. ) in a structure in which the neck portion 140 and the stopper 200 are fastened by forming a protruding rim 242 of a protruding structure that contacts the top of the cylindrical portion 142 to block or open the ventilation passage 162. Even if formed, the opening hole 144 of the neck portion 140 can be completely sealed by the protruding rim 242 as shown in FIGS. 4 and 5 .

In addition, the intake portion 160 has a plurality of intake portions 160 arranged radially along the outer periphery of the cylindrical portion 142 to secure a ventilation passage, thereby forming the stopper 200 in the direction in which the opening hole 144 is opened. As shown in FIGS. 6 and 7 , the sealing state caused by the protruding rim 242 is released, and air intake is performed vertically even when the stopper 200 is mounted on the neck portion 140 by the ventilation passage 162. Unit 160 may be configured.

That is, as shown in FIG. 8, the ventilation passage can be secured by the ventilation passage 162 even in the state where the spiral fastening parts 146 and 222 of the neck portion 140 and the stopper 200 are engaged and spirally coupled to each other. As soon as the sealing state by (200) is released, the ventilation passage is communicated, and air is sucked into the container body (100), and it is possible to prevent sloshing when discharging the contents.

Therefore, the amount of air intake flowing into the container body 100 can be adjusted by adjusting the stopper 200 mounted on the second neck portion 140b, so the stopper 200 itself is used as a valve to close or open the ventilation passage. It determines whether or not to intake air while controlling the flow rate according to the opening and closing degree of the injection cap, so it is very easy to operate and maintains the structure of the existing liquid storage bottle without the need for additional parts. As air is sucked in, the contents can be discharged stably.

In particular, by forming the intake part 160 in the neck part (second neck part) where the diameter of the opening hole is relatively larger, it is possible to sufficiently secure a passage for air intake, and by using the first neck part 140a, When discharging the contents, the ventilation passage is opened and closed using the stopper 200 mounted on the second neck portion 140b located close to the top while the container body 100 is tilted, so the contents do not flow out. or leakage can be prevented.

In addition, the intake portion 160 is formed so that the inner surface of the ventilation passage 162 is relatively more inward than the contact end (α) at which the outer periphery of the cylindrical portion 142 and the wall of the stopper 200 are engaged and fastened. Even in the state where the plug 200 is fastened to the neck 140 with the spiral fastening parts engaged with each other, a vertical ventilation passage is secured, and the ventilation passage is only achieved by the upward and downward movement of the protruding rim 242 as the stopper 200 is opened and closed. The flow rate can be adjusted by opening or closing the ventilation passage.

At this time, the intake portion 160 preferably has two or more intake portions 160 arranged radially along the outer periphery of the cylindrical portion 142, and when manufacturing the horse barrel by direct blow molding, the two intake portions 160 are formed. In order to create a mold structure that can be used, a cut surface may be formed at the parting line in the spiral fastening portion 146 of the neck portion 140. When the cut surface is formed, a ventilation passage 162 is formed to intersect the cut surface. By arranging the container body 100 in multiple ways, in the process of discharging the contents by tilting the container body 100, even when the stopper 200 is partially opened and a ventilation passage is secured, the stopper 200 is not deviated to one side and the flow path through which air is sucked is constant. can be secured.

In addition, the structure in which the protruding rim 242 is sealed while being in close contact with the cylindrical portion 142 of the second neck portion 140b is such that the outer diameter of the protruding rim 242 is in close contact with the inner diameter of the cylindrical portion 142. (242) is made to have a relatively smaller diameter than the cylindrical portion (142), and the tip of the protruding rim (242) is in order to induce sealing by pressing the protruding rim (242) when tightening and locking the stopper (200). A guide surface 244 is formed at an angle on the outer periphery.

Therefore, when mounting the stopper 200 on the second neck portion 140b, the protruding rim 242 is guided to the exact center of the cylindrical portion 142 by the guide surface 244 to induce accurate assembly, thereby increasing sealing efficiency. It can be improved.

Meanwhile, the stopper 200 has a structure fastened to the neck portion 140 as shown in FIGS. 11 and 12, and an auxiliary intake portion 260 may be formed on the inside of the stopper 200 to allow air to communicate. there is.

The auxiliary intake unit 260 has a ventilation passage 262 in which the spiral fastening part 222 is not partially formed in a vertical direction on the inner surface of the wall 220, forming a flow path to enable air intake, and the neck portion 140 ) and the stopper 200 are provided with a double ventilation passage, so that a wider ventilation passage can be secured, and the flow passage can be adjusted smoothly even by slightly manipulating the stopper 200, making it very convenient to use.

At this time, the auxiliary intake unit 260 can secure a sufficient ventilation passage by having a plurality of plug intake units 260 arranged radially along the inner periphery of the wall.

In addition, the stopper 200 has a protruding boss 280 formed vertically on the outer periphery to provide a non-slip function when opening and closing the stopper. An auxiliary intake portion 260 is formed corresponding to the position where the protruding boss 280 is formed. By arranging them radially, the overall molded thickness of the stopper 200 can be kept constant despite the structure securing the flow path by the ventilation path 262, and the formability is improved by preventing twisting during the cooling process after molding. In addition to improvement, the durability of the stopper can be improved.

In addition, if necessary, it can be used in a variety of ways because it has a structure that allows air intake by replacing the stopper with the conventional stopper.

In addition, the stopper 200 has a double protruding rim 242 in a structure to prevent minor leakage, so that when the stopper 200 is mounted on the neck part 140, the sealing with the top of the cylindrical part 142 is not possible. It can be done more efficiently.

That is, as shown in FIG. 13, the protrusion rim 242 is dually composed of an inner protrusion rim 242a and an outer protrusion rim 242b to form a double seal with the cylindrical portion 142, thereby forming the neck portion 140 and the protrusion rim 242. Even if the stopper 200 has a structure in which the flow path is opened while the cap 200 is fastened with a screw fastener, it is possible to prevent minor leakage and maintain a completely airtight state.

At this time, the inner protrusion rim 242a is preferably formed to be relatively longer than the outer protrusion rim 242b so as to be in close contact with the inner wall of the cylindrical portion 142, while the outer protrusion rim 242b is formed on the cylindrical portion 142. Double sealing can be achieved by attaching it closely to the top or outer wall.

And when a protruding frame is formed on the outer periphery of the inner protruding rim 242a in close contact with the inner wall of the cylindrical portion 142, the protruding rim presses the inner wall of the cylindrical portion outward, further increasing airtightness with the outer protruding rim 242b. This can be improved, and sequential sealing is achieved by the inner and outer protrusion rims 242a and 242b having length deviations.

That is, when closing the stopper 200, the inner protrusion rim 242a is first inserted into the inner wall of the neck portion 140 to achieve sealing, and then the outer protrusion rim 242b is sequentially brought into close contact to achieve sealing. The rim is deformed to correspond to the shape of the cylindrical portion 142 and adheres completely, and airtightness can be secured by applying appropriate tension when turning and closing the stopper. It improves the sealing effect and minimizes deformation of the stopper even when used repeatedly. can do.
