In addition, the bottle can have the structures of a first operating valve and the second operation valve which are very simple and have improved precision of opening and closing, thereby significantly reducing manufacturing costs and further increasing the reliability of the product.

Description

Automatic cap inverted container {INVERTED BOTTLE WITH AUTO CAP}

The present invention relates to an automatic cap inverted container that discharges the contents in the container body by pressing the container body, and more particularly, because it is a method of switching to an open mode or a close mode, In the open mode, the contents are discharged (discharged) very quickly and smoothly. Especially in the closed mode, since the second outlet of the second operation valve is not arbitrarily opened, the contents can be discharged even if the container body is accidentally pressed during transportation or storage. The present invention relates to an inverted container with an automatic cap, which has high product reliability because it does not leak arbitrarily, has a very simple structure of first and second operating valves, and is very convenient to discharge contents.

In general, contents such as liquid cosmetics, liquid detergent, body products such as liquid shampoo and conditioner, and liquid sauces such as soy sauce and vinegar are stored in containers and used by discharging (discharging) an appropriate amount whenever necessary.

Most containers have a discharge port (discharge port) at the top of the container to discharge the contents, but if a small amount of contents remain in the container, since the small amount of contents remains on the bottom surface of the container, a small amount of contents can be discharged through the discharge hole at the top. Since it is difficult to discharge through, it is virtually difficult to use all of the contents. For this reason, most of the containers are discarded with a small amount of contents remaining, so there is a problem of environmental pollution as well as waste of some contents.

Accordingly, a container with a discharge port formed at the bottom has been proposed. In such a container, the bottom of the container stopper (support cap) is formed flat, the container is erected vertically on a table, and the discharge port is formed at the bottom of the container stopper (support cap). is formed so that the discharge port is opened and closed when the container stopper is turned.

However, in such a container, a discharge port is formed at the bottom of the container stopper, and the contents are discharged through the discharge port in a state where foreign substances such as dust are buried around the discharge port, causing a sanitary problem in that foreign substances are mixed with the contents.

In addition, since the discharge port is formed at the lower end of the container, since the liquid contents are directed to the lower side of the container, when the discharge port is opened, there is a problem in that an unnecessarily large amount of contents are discharged and wasted.

In order to solve this problem, Korean Patent Registration No. 10-1542590 discloses an "inverted container".

1 is an exploded perspective view showing a conventional inverted type container, and FIG. 2 is a longitudinal sectional view showing a conventional inverted type container.

Referring to Figures 1 and 2, the conventional inverted type container is made of a tube type that is filled with contents and can be discharged by pressing the contents by the user, the container body 10 having a discharge port 11 formed on the lower surface; A support cap 20 having a cylindrical shape with an open lower surface, coupled to the container body 10 such that the upper surface communicates with the discharge port 11 of the container body 10, and having a lower end supported on the floor; It is movably coupled to the circumference of the discharge port 11 of the container body 10 or to the support cap 20, the lower end is located above the lower end of the support cap 20, and the contents are discharged in the center of the lower surface. an operating knob 30 formed with a ball 32; a blocking member 40 provided between the discharge port 11 of the container body 10 and the operation knob 30 and closing the discharge hole 32 of the operation knob 30 in the raised state; And a shape in which the thickness decreases from the center to the rim, and a through hole 51 through which the blocking member 40 passes is formed in the center, so that between the discharge port 11 of the container body 10 and the blocking member 40 It is interposed in, and the valve member communicates and releases the communication between the discharge port 11 of the container body 10 and the discharge hole 32 of the operating knob 30 while being deformed by the internal pressure of the container body 10 (50); It is composed by providing.

In the conventional inverted type container, as the user lowers the operating knob 30, the discharge hole 32 of the operating knob 30 opens while being spaced apart from the lower end of the blocking member 40, and presses the container body 10. As the internal pressure of the container body 10 rises, the shape of the valve member 50 is deformed so that the discharge port 11 and the discharge hole 32 communicate, so that the contents are discharged to the outside while the user presses the container. When you release your hand from the body 10, the contents remaining between the valve member 50 and the discharge hole 32 of the operating knob 30 are removed by the vacuum suction force generated while the internal pressure of the container body 10 decreases. It is configured to be sucked into the body 10.

However, in the conventional inverted type container, the lifting protrusion 31 is protruded from the inner surface of the operating knob 30, and the lifting protrusion 31 is the lifting groove 27 of the fitting end pipe portion 21 of the support cap 20. ), and is configured to move along the elevating groove 27, so that the operation knob 30 is lowered from the container body 10 by turning the operating knob 30 to discharge the contents from the container body 10. At this time, the elevating groove 27 ), the lifting protrusion 31 moves along.

In the conventional inverted type container, the user first turns and lowers the operating knob 30 to open the discharge hole 32 of the operating knob 30, and then presses the container body 10 so that the container body 10 As the internal pressure increases, the pressure applied to the upper surface of the valve member 50 increases, so the edge of the valve member 50 sags and a gap is generated between the inner circumferential surface of the fitting end pipe portion 21 of the support cap 20 to prevent contents It flows into the discharge hole 32 of the operating knob 30 through the gap and is discharged to the outside. In such a conventional inverted container structure, the user firstly opens the discharge hole 32 of the operating knob 30, and then presses the container body 10 secondly to increase the internal pressure of the container body 10, thereby increasing the content of the contents. Because of this discharge configuration, the plate member 50 is absolutely necessary to prevent the contents from being arbitrarily discharged through the discharge hole 32 .

However, the conventional inverted type container has the advantage that the valve member 50 prevents the contents from being arbitrarily discharged through the discharge hole 32, but has a problem in that the contents are not smoothly discharged by the valve member 50. That is, when a large amount of content is to be discharged, the valve member 50 is rather an obstacle and there is a problem in that the content cannot be smoothly discharged.

In addition, in the case of a conventional inverted type container, when it is desired to stop dispensing the contents (when the container is stored upright), the user first rotates the operation knob 30 in the opposite direction to raise it to its original position, and then the discharge hole of the operation knob 30 (32) must be closed so that the contents are not discharged to the outside of the container body 10 through the discharge hole 32, and the user must turn the operating knob 30 in the opposite direction to raise it to its original position. There are inconveniences to be had.

In addition, in the conventional inverted container, if the operating knob 30 is not raised immediately after use, residual contents flow between the valve member 50 and the discharge hole 32, contaminating the area around the discharge hole 32 and drying the contents. There may be problems with hardening.

In addition, Korean Patent Registration No. 10-1357310 discloses "an automatic cap opening and closing device for a liquid container".

However, in the conventional automatic cap opening and closing device for a liquid container, since the size of the opening and closing member 30 that allows the contents to be discharged or blocked as the user presses the container 10 is larger than the inlet of the container 10, when assembling or When refilling the contents, it is very difficult to insert or remove the opening/closing member 30 into or out of the inlet of the container 10 .

In particular, when the contents inside the container are used up and the contents are to be refilled, the inner member 33 of the container with the contents is held by hand and pressed to reduce the volume, and then inserted into the inlet of the container 10. , The refilling operation is very inconvenient, and the structure of the automatic cap opening and closing device is complicated, the number of parts is large, and assembly is difficult, resulting in poor assembly quality and high manufacturing cost.

In addition, although not disclosed in the drawing, Korean Patent Registration No. 10-2281936 discloses an "auto-cap inverted container".

In a conventional automatic cap inverted container, when a user holds and presses the container body, the operating knob descends in the vertical direction due to the discharge pressure within the container body. There is a concern that the content cannot be discharged smoothly because it cannot descend quickly in the vertical direction, and when the user stops pressing the container body, the operating knob rises in the vertical direction due to the elastic restoring force of the elastic member. When the elastic member is deformed due to long-term use, there is a concern that the contents may leak due to delay in raising the operating knob.

This is to precisely align and assemble the assembly positions of the first operation valve 140 and the second operation valve 150 during the manufacturing process of the automatic cap inverted container 100 so that the two outlets 151 are open or blocked.

In addition, as shown in FIGS. 15 and 18 to 20, the check valve module 160 includes a check valve frame 161 installed in the outlet 131; and a two-way check valve 162 installed on the check valve frame 161 and formed of an elastic material (eg, rubber); to provide A cross-shaped slit 163 is formed at the center of the two-way check valve 162.

The cross-shaped slit 163 is normally blocked (shown in FIGS. 17 and 18), but when the user presses the container body 110 in the open mode, the internal discharge pressure of the container body 110 increases, thereby discharging the contents. After flowing out through the first discharge port 141 and the second discharge port 151, it is discharged (discharged) to the outside of the container body 110 as it is opened elastically (shown in FIGS. 19 and 20).

Hereinafter, the operation of the automatic cap inverted container according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

First, when the product containing the contents in the automatic cap inverted container 100 is shipped, as shown in FIGS. 19 and 20, it is shipped after being set to a close mode (close mode or locking mode), so that the second operation valve ( The second discharge port 151 of 150) is blocked to prevent the contents from leaking arbitrarily.

Since the second outlet 151 of the second operation valve 150 is not arbitrarily opened and maintains a blocked state even if the container body 110 is pressurized as it is set to the close mode (close mode or locking mode) as described above, , Even if the container body 110 is accidentally pressed during the distribution process of the product, the contents do not leak arbitrarily, so the reliability of the product can be further increased.

Meanwhile, as shown in FIGS. 19 and 20 , when discharging the contents of the container body 110, the user (consumer) holds the handle 138 of the rotary knob 130 and turns the rotary knob 130. Rotate it 90° counterclockwise to switch to open mode (or unlocking mode). At this time, the first outlet 141 of the first operation valve 140 and the second outlet 151 of the second operation valve 150 are connected and open.

Then, when the user presses the container body 110 (shown in FIGS. 19 and 20), the internal discharge pressure of the container body 110 increases, and the contents pass through the first and second outlets 141 and 151. After flowing out through, as the cutting slit 163 of the check valve module 160 is opened, it is quickly and smoothly discharged (discharged) to the outside of the container body 110 .

In the automatic cap inverted container 100 of the present invention, when the container body 110 is elastically returned to its original position after the contents are discharged, the incision slit 163 is generated by the increase in internal suction pressure of the container body 110. ) also elastically returns to the original position, the incision slit 163 of the check valve module 160 is elastically blocked to prevent the discharge of the contents to the outside of the container body 110, and although not shown in the drawings, the incision slit (163) External air is introduced into the container body 110 by the amount of the contents discharged immediately before closing to balance the internal pressure of the container body 110.

Then, the user rotates the rotary knob 130 clockwise again by 90° to switch to a close mode or locking mode, so that the second outlet 151 of the second operation valve 150 is blocked and the contents This can effectively be prevented from leaking arbitrarily (shown in Figs. 17 and 18). In other words, as the rotary knob 130 is rotated clockwise by 90°, the first outlet 141 of the first operation valve 140 and the second outlet 151 of the second operation valve 150 are not connected. The second outlet 151 of the second operation valve 150 is blocked so that the contents do not leak arbitrarily.

Since the second discharge port 151 of the second operation valve 150 is not arbitrarily opened according to the switch to the close mode (close mode or locking mode) in this way, the container body 110 while the user is carrying or carrying and storing Even if is pressed incorrectly, since the contents do not leak arbitrarily, the reliability of the product can be further increased.

As described above, the present invention has the following effects.

First, since the rotation knob is rotated 90° counterclockwise to switch to open mode, or the rotation knob is rotated 90° clockwise to switch to close mode, in open mode The discharge of the contents is very quick and smooth, and since the second discharge port of the second operation valve is not arbitrarily opened, especially in the closed mode, the container body is not accidentally pressed during product distribution or during transportation or storage by the user. There is no fear that the contents will leak arbitrarily even in the case of

Second, the structure of the first check valve and the second check valve of the operating valve is very simple and has excellent opening and closing precision, thereby significantly reducing manufacturing costs and further increasing reliability of the product.

Third, unlike conventional automatic cap opening/closing devices for liquid containers, the size of the opening/closing structure for preventing discharge and leakage of the contents is smaller than the opening of the container body, and the overall structure is simple and easy to assemble because the number of parts is small. It has the effect of reducing the manufacturing cost and has the advantage of very convenient refilling operation when refilling the contents.
