Description

Airtight Containers {Airtight container}

The present invention relates to an airtight container, and more particularly, it is possible to seal or open a container lid without using a bolt or clamp, so that the container cover can be easily opened and closed, and the compression and vacuum state are kept simple. It relates to an airtight container that is convenient for spillage and can hold various objects or materials.

      Sealed containers of various structures and modes of operation are known. In general, the sealed container has a container body in which a closed end and a closed rim are formed in an upper opening circumference region, and opens and closes an upward opening of the container body, and has a lid in which a packing coupling part is formed at a lower portion corresponding to the closed end.

      In addition, the lid coupling portion coupled to the packing coupling portion and the bottom contact surface is formed in contact with the closed end portion at the lower end, and the side contact portion and the packing coupling portion and the closed rim between the packing coupling portion and the outer end surface It has a closed rim contact part in between. It also has a separate opening and closing means in order to maintain a closed state and to not open the lid arbitrarily.

     The container body side and the lid are in contact with each other by inserting a suitable rubber packing or a material suitable for maintaining the airtight state to keep the airtight state so that the airtight state between the container body and the lid is maintained. The means are operated to open and close the lid.

      The opening and closing means applied to the sealed container varies in structure and form depending on the combination of the container body and the lid. In general, an opening and closing structure is also known in which a clamp is attached to a container body or a lid and the lid is held in close contact with the container body by clamping the clamp, or a fastener having a tightening force such as a bolt is directly mounted.

      On the other hand, a closed container that does not depend on the opening and closing means must be opened between the container body and the lid contact surface, and thus a separate opening and closing means is inevitably applied because it cannot maintain the sealed state in the container body. And the like.

      As described above, the conventional airtight container to which the opening and closing means is applied has the following problems.

      First, the operation is cumbersome and inconvenient when the lid is coupled to the container body. In other words, in order to couple the lid to the container body it is necessary to tighten all the clamps or fasteners, so the operability is poor.

      Second, the clamps and fasteners mounted on the container body and the lid are a cause of deterioration of the airtightness by the deterioration of the bonding force due to wear and deformation by repeated operation, thereby reducing the shelf life of the sealed container.

      Third, in the case of applying the clamp and the fastener as an opening and closing means of the sealed container, the clamp and the fastener are structurally separated from the container body, causing a loss of the sealing function.

      Fourth, in mounting the clamps and fasteners in the container body or lid, there is a problem in that the economic efficiency is also reduced due to the increase in manufacturing costs by combining the individual parts through a number of processes.

      Therefore, the present invention has been made in view of the above circumstances, and the present invention has an object to provide a closed container that is easy and simple to operate when the lid is coupled to the container body.

      Another object of the present invention is to provide a high-performance sealed container that extends the shelf life of the sealed container by reducing the airtight performance due to wear and deformation by allowing the container body and the lid to be simply combined and separated without separate attachments. It is.

      Still another object of the present invention is to provide a sealed container that can be economically manufactured at low cost by allowing a simple and concise production of a sealed container composed of a container body and a lid.

     The head 15 is formed to have a diameter larger than that of the body 16, and a step 17 is formed between the head 15 and the body 16 due to the diameter difference. Here, the head 15 has a larger diameter than the body 16 to guide the passage hole 22 constituting the fastening hole 21 of the lid 20 along the head 15 to be fitted. At the same time, the gap 23 narrower than the passage hole 22 of the lid 20 is moved in the circumferential direction along the body 16 of the stopper 14 at the position where the fitting position is shifted. It is to be coupled to the container body 10 without being caught by the step (17).

     In addition, the upper surface 13 of the container body 10 is preferably configured to be in close contact with the contact surface for maintaining the airtight contact with the sealing member (30).

     As described above, the fastening hole 21 has a passage hole 22 having a size larger than that of the head 15 of the stopper 14 so that the head 15 of the stopper 14 can be inserted therethrough. And a gap 23 formed from the passage hole 22 and split along the circumferential direction of the lid 20, so that the gap 23 is fitted in the state of being fitted into the body 15 of the stopper 14. The lid 20 is not separated from the moving position so that the lid 20 can be moved through the container body 10, and thus, the lid 20 is coupled to the container body 10. Accordingly, when the lid 20 is rotated within the area range of the gap 23 by fitting the fastening hole 21 of the lid 20 in accordance with the stopper 14 protruding from the container body 10, the rotation position thereof Since the sealed state is maintained in the container body 10 and the lid 20 does not require any other operation to maintain the airtightness.

     In addition, the fastening hole 21 is formed at a corresponding position of the stopper 14, the position is preferably formed along the edge of the lid (20).

    In addition, the compression and vacuum control unit 40 is configured on the outside of the lid 20, the head (opened with a flow path 41) for guiding external air inflow and fluid flow inside the container body 10 ( 42, an air inlet 43 connected to the flow path 41, and an air inlet 43 for injecting outside air into the container body 10 through the head 42 side flow path 41.

It consists of an outlet 48 extending from the fluid outlet 45 in order to.

      In addition, the air inlet 43 may be provided with a blocking film 49 to prevent the reverse flow of air introduced into the container body 10, and to block the inflow of external air. The blocking film 49 may be equipped with a valve body or may be configured by covering a separate cap with the air inlet 43.

     In addition, the fluid outlet 45 may be configured by selectively installing an extension pipe 50 that can reach the bottom of the inner space 12 of the container body 10.

     The airtight container 100 according to the present invention configured as described above can easily and quickly and accurately couple the lid 20 to the container body 10, and the fluid in the container body 10 through the container body 10 is compressed. It can be leaked to the outside, and at the same time there is a feature that can be maintained in a vacuum state.

     3 shows a process of coupling the lid 20 to the container body (10). The stopper () protruding from the container body 10 guides the fastening hole 21 formed in the lid 20 to be fitted. When the lid 20 is coupled to the container body 10, the gap between the contact surfaces of the lid 20 in contact with the upper surface 13 of the container body 10 does not open due to the self sealing function of the sealing member 30. Sealing member 30 may be formed in the form of a rubber that is commonly used to put between the contact portion of the container body 10 and the lid 20 so that there is no gap between the contact surface.

     When fitting the fastening hole 21 of the lid 20 to the stopper 14 of the container body 10, the through hole 22 of the fastening hole 21 is fitted to the head 15 of the stopper 14. . Since the passage hole 22 is formed in a size larger than the head 15 of the stopper 14, it is inserted into the head 15 of the stopper 14 as it is. In the figure, four stoppers 14 and fastening holes 21 are shown at corresponding positions. As such, when the lid 20 is coupled to the container body 10, the through hole 22 of the fastening hole 21 is formed at a corresponding position in each of the stopper 14 heads 15. .

     In order to continuously maintain the closed state, as shown in FIG. 3, when the lid 20 is only slightly rotated in the direction "A" in which the gap 23 is formed, the gap 23 along the body 16 of the stopper 14 is maintained. ) Is moved so that the lid 20 is not separated at the moving position, and the state of being coupled with the container body 10 is maintained. That is, the gap 23 formed in the fastening hole 21 of the lid 20 is engaged with the step 17 formed between the head 15 and the body 16 of the stopper 14 to reengage the position of the gap 23. It does not separate unless it is moved to its previous state.

     Accordingly, the lid 20 is fitted to the stopper 14 protruding from the container body 10 so as to fit the passage hole 22 formed in the fastening hole 21 of the lid 20 in the area of the gap 23. Rotating) maintains the sealed state at the rotational position thereof, so that no other manipulation is required to maintain the airtightness of the container body 10 and the lid 20 so that the lid 20 is coupled to the container body 10. This is easy and simple. In addition, since the fastening hole 21 is inserted and inserted into the stopper 14, the coupling position of the lid 20 can be accurately coupled without causing a coupling failure such as shifting or twisting of the lid 20.

      Meanwhile, the fluid in the container body 10 may be leaked to the outside through the compression of the inside of the container body 10, and at the same time, the vacuum may be maintained. This is possible by controlling the flow state of the fluid through the compression and vacuum control unit 40 installed on the outside of the container body (10).

      For example, when the liquid content 60 is put into the space 12 in the container body 10 in FIG. 5 and compressed air is injected from the outside through the air inlet 43, the air injection hole 44 is used. Compressed air exerts a pressure on the space 12 in the container body 10. The air injection method through the air inlet 43 may be injected using a pump or the like.

      The fluid inside the container body 10 that continuously injects air into the container body 10 is expanded. At this time, when the operation valve 46 is opened, the contents 60 are discharged through the fluid outlet 45 along the extension pipe 50 until the space 12 in the container body 10 approaches the atmospheric pressure state. Is discharged.

      Through this, after the liquid content 60 is put into the container body 10, the contents 60 stored in the container body 10 can be discharged by air pressure by forced injection of external air without opening the lid 20. have.

     In the method of storing the contents 60 in the container body 10, as shown in FIG. 5, the contents 60 may be directly stored in the container body 10 and stored in a separate small container. Irrespective of the extension of the extension pipe 50 to the position where the contents 60, the outflow is possible.

     On the other hand, without injecting air through the air inlet 43, on the contrary, the air inside the container body 10 is forced out through the air inlet 43 to maintain the space 12 in the container body 10 in a vacuum state. It is also possible.

     On the other hand, the airtight container according to the present invention is in close contact with the inner and outer contact surface of the container by the fluidity of the sealing member 30 after the compression sealing lid 20 is moved upward, the airtight state is maintained, the stopper 14 after compression sealing ) Prevents the separation of the lid 20 and preserves the position of the sealing member 30, the container 10 and the lid 20 is coupled in a natural coupling state without interference during compression and vacuum.

     As described above, the airtight container according to the present invention can contain various materials such as paints, industrial oils, cutting oils, and other various substances such as water, liquid liquids for drinks, and can be discharged without directly opening the lid by injecting compressed air, and also various industrial uses. And it can be used as a food and beverage storage container, and because it can maintain the internal vacuum state can store a variety of materials or articles requiring vacuum storage such as oxidizing materials, ignitable materials.

     While the invention has been described in connection with the preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications are set forth in the claims. Belongs to the range.
