JP6810798B2 - Container with automatic lid opening and closing - Google Patents

Description

The present invention relates to a container used by containing various contents. More specifically, when the container is lifted from the floor, the upper lid is automatically opened, and when the container is lowered again on the floor after use, the upper lid is automatically closed. As a result, the container can be used without opening and closing the lid separately, and thus the container has an automatic lid opening / closing method, which is excellent in convenience and hygiene.

Generally, when packaging various liquid, gel, and powder contents, they are mainly packed in a container.

Such a container is composed of a container body and an upper lid that is coupled to the upper part of the container body and used for opening and closing.

In such a conventional container, when the contents are taken out and used, the upper lid on the upper part of the container body is opened or another opening / closing tool provided on the upper lid is opened to take out the contents and used.

That is, conventionally, the user is required to open the upper lid of the container or the opening / closing tool of the upper lid separately to take out the contents and use the container, and after use, close the opening / closing device of the upper lid or the upper lid again. There was a problem that it was very inconvenient to take out the contents and use them.

In particular, when using with contents such as cosmetics, when closing the top lid or opening / closing tool again after using the contents, the cosmetics on the hand slip when handling the container and re-open the top lid or opening / closing tool. Not only is the closing operation more inconvenient, but there is also the unsanitary problem of contaminating the outside of the container with cosmetics.

In order to improve such a problem, a technique for automatically taking out and using the contents of the container is disclosed. For example, a tension coil spring and a compression coil spring are used on the inner side of the outlet of the container lid to oppose each other. A pair of operating ball valves are provided, and when the container is lifted and pressurized during use, the valve is automatically opened by the pressing force and the contents flow out, and when the pressing force on the container is released, the valve is closed. Not to mention, the residual contents in the outlet are made to flow into the inside of the container again, improving the convenience of use.

However, when the container is lifted and pressurized, the valve is opened by the pressing force to take out the contents and used, and when the container is put upright again after the pressing force is released, the valve is closed. Therefore, there is a problem that the convenience of use is limited because the valve is opened and closed semi-automatically by the operation of pressurizing the container separately from the operation of lifting the container.

In addition, the above-mentioned container has a problem that the container easily collapses when it is used upright on the floor or stored in a bag, and when it is carried, and the valve is opened by applying an external force to the container regardless of the user's intention. There is a problem that the contents may be unnecessarily leaked, and there is no separate technology to prevent this.

A ring-shaped sealing member 33 is inserted into the ceiling member 33 to form a coupling.

The lower cradle 50 is composed of an upper fixing member 51 that is fixedly connected to the lower part of the outer container and a lower actuating member 55 that is vertically movablely connected to the lower part of the upper fixing member together with the inner container 20.

The lower actuating member 55 is inserted in the center of the upper fixing member 51 by providing an insertion tube portion 56 in the center of the upper portion and providing a guide protrusion 57 at an equiangular position on the outer circumference of the insertion tube portion. The hole 52 and the guide hole 53 provided on the outer circumference of the insertion hole are coupled so as to be guided up and down, but the stop protrusion 57a projecting from one side of the guide protrusion and the upper fixing member The vertical guide groove portion 54a formed vertically on the inner partition wall 54 and vertically guides the stop protrusion portion is configured to limit the elevating guide distance.

At this time, a lock groove 54b horizontally extended in the circumferential direction is connected to the upper portion of the vertical guide groove portion 54a, and the stop protrusion 57a is inserted into the lock groove by rotation of the lower actuating member 55. It is configured to limit the lifting operation of the upper fixing member and the lower operating member (lock operation).

That is, even if the outer container 10 is lifted from the floor, the inner container 20 and the lower actuating member 55 of the lower cradle 50 do not move up and down, and the opening / closing tool 43 keeps the content supply hole 42 in the closed state. ..

Further, a suction plate 61 is assembled and installed on the bottom surface of the lower actuating member 55 of the lower cradle 50. By providing the suction hole 62 in the center of the upper part of the suction plate, a low cap is provided when the external container is lowered to the floor. The lower actuating protrusion 36 is inserted into the suction hole 62 to perform suction operation, or when the external container is lifted from the floor, the lower actuating protrusion 36 is separated from the suction hole 62 to perform suction release operation. ..

At this time, a guide pipe portion 37 is projected from the lower part of the low cap 35 to the outside of the actuating protrusion 36, and the guide pipe portion is inserted into the insertion pipe portion 56 of the lower actuating member to perform the elevating guidance operation. By forming notch grooves 37a at equal angles in the vertical direction on the outside of the guide pipe portion 37, the notch grooves 37a are elastically actuated inward and outward at the time of assembly to improve the assembling property, and external air flows in at the time of adsorption or release.

In the suction plate 61, the coupling projection 66 of the coupling tool 65 to be coupled from the lower portion is provided in the assembly hole 63 of the suction plate and the coupling groove 56a provided on the lower circumference of the insertion pipe portion 56 of the lower operating member 55. It is configured to be fitted and fixedly coupled so as to prevent detachment.

As unexplained reference numerals, 38a and 38b indicate a locking projection that is engaged with the ends of the guide tube portion 37 and the insertion tube portion 56 so as to prevent disconnection, and 41a indicates a shaft pin assembly groove.

Next, the operation and operation of the present invention configured as described above will be considered.

First, when the container of the present invention is lowered to the floor, the lower cradle 50 at the lower part of the outer container 10 rests on the floor.

At the same time, in the lower cradle 50 below the outer container 10, the upper fixing member 51 moves downward by the lower operating member 55 due to the weight of the outer container.

At this time, the central insertion hole 52 of the upper fixing member 51 is guided downward by the central insertion tube portion 56 of the lower operating member 55, and the lower operating member 55 is inserted into the guide hole 53 on the outer circumference of the insertion hole. The guide protrusion 57 is guided downward.

In particular, the upper fixing member 51 descends within a vertical movement range in which the stop protrusion 57a projecting from one side of the guide protrusion is guided by the vertical guide groove 54a formed vertically on the partition wall 54 inside the upper fixing member. To do.

At the same time, the outer container 10 moves downward while compressing the tension member 70 installed between the outer container 10 and the inner container 20.

While the outer container 10 moves downward in this way, the opening / closing tool 43 of the upper lid supported by the stopper 23 at the upper part of the inner container is pushed up upward, so that the opening / closing tool 43 is centered on the shaft pin 43b. The axis rotates upward.

At this time, the opening / closing tool 43 is inserted and guided into the guide groove portion 43a of the main body 41 of the upper lid to rotate the shaft.

The content supply hole 42 provided in the upper center of the upper lid is closed by the upward axial rotation of the opening / closing tool 43.

At this time, the sealing cap 45 of the opening / closing tool 43 is in close contact with the content supply hole 42 and the ring-shaped sealing member 33 inserted into the discharge port 32 of the content container to airtightly shut off the content supply hole 42. ..

By lowering the outer container 10 to the floor in this way, the opening / closing tool 43 of the upper lid automatically closes the content supply hole 42.

At the same time, when the outer container 10 is lowered to the floor, the outer container 10 and the upper fixing member 51 of the lower cradle are guided downward, and the contents container 30 inside the outer container also moves downward.

The lower guide pipe portion 37 of the low cap 35 coupled to the lower portion of the contents container protrudes into the guide pipe portion 37 of the low cap while moving downward along the insertion pipe portion 56 of the lower actuating member. The provided actuating protrusion 36 is inserted into the suction hole 62 at the center of the upper part of the suction plate 61 coupled to the bottom surface of the lower actuating member so that the suction plate 61 is suction-operated.

That is, when the outer container 10 is lowered to the floor, the lower suction plate 61 automatically sucks and operates, thereby preventing the container from falling due to an external force.

When the contents inside the container are to be used in such a state, when the outer container 10 is grasped and lifted from the floor again, it is installed between the outer container 10 and the inner container 20 as described above. Due to the elastic force of the tension member 70 and the weight of the inner container 20 and the lower actuating member 55 of the lower cradle, the lower actuating member 55 of the lower cradle and the inner container 20 move downward in the outer container 10.

At this time, the central insertion tube portion 56 of the lower operating member 55 is guided to the central insertion hole 52 of the upper fixing member 51, and the lower operating member is guided to the guide hole 53 provided on the outer circumference of the insertion hole. The guide protrusion 57 of 55 is guided downward.

In the lower actuating member 55, the stop protrusion 57a projecting from one side of the guide protrusion is lowered to a vertical movement range guided by the vertical guide groove 54a formed perpendicularly to the partition wall 54 inside the upper fixing member. To limit.

At the same time, the insertion pipe portion 56 of the lower actuating member is pushed down into the guide pipe portion 37 while being moved downward by the guide pipe portion 37 at the lower part of the low cap 35 coupled to the lower portion of the content container. The outer container can be easily lifted from the floor by releasing the actuating protrusion 36 while being inserted into the suction hole 62 in the upper center of the suction plate 61 and automatically canceling the suction operation of the suction plate 61. ..

At this time, air is circulated inside the insertion pipe portion 56 by the notch groove 37a provided in the vertical direction on the outside of the guide pipe portion 37, and the working projection 36 is easily separated from the suction hole 62 in the upper center of the suction plate. To do.

That is, when the outer container 10 is lifted from the floor, the suction operation of the lower suction plate 61 is automatically released, and the container is easily lifted.

When the outer container 10 is lifted from the floor and the inner container 20 is guided to move downward by the tension member 70 in this way, the opening / closing tool 43 of the upper lid supported by the upper stopper 23 of the inner container becomes the opening / closing tool operating portion. The axis is rotated downward by 44.

This is because the opening / closing tool 43 rotates about the shaft pin 43b axially coupled to the shaft hole 43a, but is inserted into the shaft pin, one side is fixed to the main body 41 of the upper lid, and the other side is opened / closed. The elastic force of the torsion spring 46 fixed to the tool 43 causes the axial rotation to rotate downward.

At this time, the opening / closing tool 43 is inserted and guided into the guide groove portion 43a provided in the main body 41 of the upper lid to rotate the shaft.

In this way, while the opening / closing tool 43 rotates about the axis downward, the content supply hole 42 blocked by the opening / closing tool is automatically opened.

That is, the user automatically opens the content supply hole 42 by lifting the outer container 10 from the floor, and easily takes out and uses the content.

On the other hand, when the container of the present invention is carried and stored, the opening / closing tool 43 of the upper lid is locked so as not to automatically open / close.

This pushes the outer container 10 downward or pushes the lower actuating member 55 upward with the lower cradle 50 on the lower side of the outer container, and moves the lower actuating member 55 so as to rise by the upper fixing member 51.

At this time, the stop protrusion 57a projecting from one side of the guide protrusion of the lower actuating member 55 moves up and down along the vertical guide groove 54a vertically formed on the partition wall 54 inside the upper fixing member.

In this state, the lower actuating member 55 is rotated in one direction by the upper fixing member 51, and the stop protrusion 57a is inserted into the lock groove 54b horizontally extended in the circumferential direction above the vertical guide groove 54a. It limits the raising and lowering operation of the upper fixing member and the lower operating member (lock operating state).

At this time, the opening / closing tool 43 of the upper lid moves horizontally as described above to maintain the content supply hole 42 in the closed state.

That is, in the locked operating state, by lifting and lowering the outer container 10 from the floor, the lower operating member 55 of the inner container 20 and the lower cradle 50 does not move up and down, and the opening / closing tool 43 moves to the content supply hole 42. Because the container is kept closed, the container can be safely carried and stored inside a bag or the like.

Therefore, the present invention includes an outer container, an inner container that is vertically movable inside the outer container, a content container that is inserted inside the inner container and fixedly connected to the outer container, and the outer container. The container is floored by including an upper lid that is coupled to the upper part of the container and opens and closes the content supply hole by an opening / closing tool, and a lower cradle that is coupled to the lower part of the outer container and is coupled so as to be movable up and down. When lifted from, the inner container and lower cradle move to the lower part, and the opening and closing tool of the upper lid interlocks to automatically open the contents supply hole, and when the container is lowered to the floor again after use, the inner container and lower cradle are lowered. The opening and closing tool of the upper lid interlocks to automatically close the contents supply hole while moving to the upper part, so the lid can be automatically opened and closed without opening and closing the lid separately. It is convenient and can be used hygienically.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto, and it goes without saying that various modifications and changes can be made within the scope of the following claims.
