Description

Vacuum container

The present invention relates to a vacuum container, and more particularly, to a vacuum container provided with a valve device and a pump device.

In general, the long-term storage of food is a method of refrigerated storage or vacuum storage. In the case of vacuum storage of food, a vacuum pack may be used, but usually, the food is contained in the container body, the lid is combined, and the inside of the container body is vacuumed with a vacuum apparatus. When the food is stored in a vacuum state, the oxidation of the food does not occur, so the food does not decay and can be stored for a long time, and furthermore, the inherent aroma of food can be preserved as it is. There is a lot of development. For example, U.S. Patent No. 5,405,038 to Chuang, U.S. Patent Publication No. 2008 / 0061063A1 to Kim, and the like disclose a vacuum vessel equipped with a valve device having a relatively simple configuration.

Conventional vacuum containers for long-term storage of food is typically provided with a valve device for discharging air in the vacuum container on the lid of the vacuum container, and then vacuums the inside of the container using a separate vacuum pump. In such a case, it is cumbersome because a separate vacuum pump must be provided, and the vacuum pump itself may be more expensive than the vacuum container when using a vacuum pump that is easily operated by electricity.

A vacuum vessel has been developed in which a vacuum pump is provided at the lid of the vacuum vessel. Korean Patent Registration No. 1002507 by the present applicant discloses a vacuum vessel equipped with a vacuum pump. Here, the vacuum pump is configured to generate air suction force by the restoring force when the spring is compressed, but there is a problem in that the pump action is not practical because there is a limit in generating the air suction force by the restoring force of the spring. Therefore, there is a demand for the development of a vacuum vessel equipped with a valve device and a pump device, which operates smoothly and has low manufacturing cost.

After the vacuum is generated in the vacuum vessel, the degree of vacuum gradually weakens with time, so it is necessary to increase the degree of vacuum in the vessel at an appropriate time. At this time, if the user can know the degree of vacuum inside the container, it will be very convenient.

An object of the present invention is to provide a vacuum vessel provided with a valve device and a pump device.

Another object of the present invention is to provide a vacuum container which is provided with a valve device and a pump device in the vacuum container are compactly received in the container lid.

Still another object of the present invention is to provide a vacuum container in which a valve device and a pump device are provided in the vacuum container, and the pump device operates easily.

Still another object of the present invention is to provide a vacuum container further provided with a vacuum releasing device capable of simply releasing the vacuum in the vacuum container.

It is still another object of the present invention to provide a vacuum display device which displays the degree of vacuum in a container of a vacuum container, but whose structure is simple and reliably operated.

In order to achieve the above object, the present invention provides a vacuum container having a vacuum device set on the vacuum container lid extending in the direction of the container body and having a valve device and a pump device located therein. The valve device serves to flow the air in the container body in one direction to the outside of the container body, and the pump device to suck the air in the container body.

In the vacuum device according to the present invention, a valve device is formed at the bottom of the vacuum container set-up, and the pump device is compactly formed on the container lid by configuring the pump device to be positioned directly above the valve device. The pump device also includes a cover that encloses the vacuum apparatus and is tightly fixed to the vacuum chamber mounting portion, a rod portion reciprocating in the cover, and a handle fixed to one end of the rod portion and gripped to reciprocate the rod portion. The cylinder-operated air pump system allows for easy operation without extra power. In addition, the handle is axially rotatably fixed to one end of the rod portion, the handle seating portion is formed in the lid of the vacuum container, when the handle is not used, the handle can be placed in the handle seating, it looks beautiful and pump device Becomes more compact.

The lid of the vacuum container according to the present invention further includes a vacuum release device. This vacuum release device is formed in the receiving groove so that it looks good and prevents the release device from being inadvertently operated. The vacuum releasing device is formed in a vacuum releasing device receiving groove formed in the lid of the vacuum container, is formed integrally with the bottom of the receiving groove, and comprises a valve seat portion having a valve seat ball, and the valve seated in the valve seat portion The configuration is very simple. At this time, the valve has a hollow portion formed over the entire length of the fuselage and is opened to the lower portion of the valve so that the valve can be easily seated in the valve seat portion, and the valve is simply pressed from the valve seat portion by pressing the valve head. The vacuum in the vessel body can be released by separating.

The lid of the vacuum container according to the present invention further includes a vacuum display device for displaying the degree of vacuum generated in the vacuum container.

The vacuum display device includes a vacuum indicator, an elastic corrugated pipe portion having the vacuum indicator attached to one end thereof and having a hollow portion therein, and a container portion in which the vacuum indicator and the corrugated pipe portion are placed. The container part has a ventilating body communicating with the inside and outside air of the container part, and a plate-like body having a vacuum display part capable of knowing the degree of vacuum, a lower body having an opening opening through which the corrugated pipe part to which the vacuum indicator is attached and which can enter and exit is provided. It has a connection hole for communicating the hollow part of the corrugated pipe part and the inside of the vacuum container, and comprises a stopper for sealing the opening of the lower body, but the hollow part of the corrugated pipe part communicates with the connecting hole of the stopper but not with the inner space of the container part. Therefore, when a vacuum is generated inside the vacuum container, the inner space of the container communicates with the outside atmosphere through the air vent, but is separated from the hollow part of the corrugated pipe part, so that the corrugated pipe part contracts by atmospheric pressure, and the degree of contraction is the inside of the vacuum container. Will be proportional to the degree of vacuum. Preferably, the vacuum display device according to the present invention is hermetically housed in a vacuum display device mounting portion in which a vacuum display device is placed on a lid of a vacuum container.

The vacuum container according to the present invention is very convenient because the lid is provided with a vacuum device consisting of a valve device and a pump device to form a vacuum in the container without a separate vacuum pump. This vacuum device is preferable because the vacuum pump is constituted by a cylinder-operated air pump device so that the vacuum pump can operate without a separate power, and the valve device and the vacuum pump are integrally formed in the vacuum device set-up part, thereby making it compact.

The vacuum container according to the present invention comprises a valve seat portion and a valve seated on the valve seat portion, and has a vacuum releasing device having a very simple configuration, and the valve is easily seated on the valve seat portion and is simply a container. The vacuum in the body is released, which is very convenient for use. Since the vacuum display device according to the present invention displays the degree of vacuum in the vacuum container relatively, but expresses it relatively accurately, when the device is attached to the lid of the vacuum container, the usability of the vacuum container is further improved.

In addition, a portion of the handle seat 7 is formed on the cover upper surface 44 as shown.

The rod part 50 is comprised from the circular plate-shaped part 55 and the center rod 51 integrally formed with this plate-shaped part. The plate portion 55 is formed with an O-ring insertion groove 57 into which the first O-ring 77 to be described later is inserted along the outer circumference of the plate-shaped portion. As the O-ring inserting groove 57 is formed, the plate-shaped portion 55 is separated into an upper plate 56 and a lower plate 58, and an upper plate groove 59 is formed in the upper plate 56. The upper plate groove 59 is connected to the O-ring insertion groove 57. On the other hand, the plate portion 55 is formed so that the hollow portion 49 of a size that is enough to accommodate the valve device 20 to be described later is opened to the lower side (see Fig. 8). The central rod 51 has a rod shape extending upward from the center of the plate portion 55, the handle portion 53 is formed in the end region 52 to which the handle 60 to be described later is coupled. The central rod 51 is provided with a hollow portion 51 'extending in the longitudinal direction thereof (see FIG. 8), and the lower side of the hollow portion 51' communicates with the hollow portion 49 of the plate portion. . This hollow portion 51 'is not an essential element but is intended to help reduce the load on the central rod 51 to facilitate the reciprocating motion.

The handle 60 gripped to reciprocate the rod part 50 is fixed to one side end of the rod part 50, that is, the handle engaging portion 53 of the end region 52 of the central rod 51. The handle 60 has a grip 61 formed to be easily gripped. The handle 60 is preferably fixed to the handle coupling portion 53 so as to be rotatable. To this end, in the illustrated embodiment, the handle 60 has a bifurcated branch 63 is formed inside the handle 63, the handle protrusion 65 is formed, the handle engaging portion 53 is the handle protrusion ( 65 is implemented in the form of a hole in which it is received. On the other hand, any configuration in which the handle 60 is axially fixed to the end region 52 of the central rod 51 may be used in the present invention, for example, the handle 60 to the end region 52. It may be axially coupled by a pin.

As can be seen from FIGS. 1, 3, and 4, the lid 3 is provided with a handle seat 7 extending through the top surface 44 of the cover 41, so that the handle 60 is provided with a pump device ( 40) If it is not operated, it is rotated and placed on this seating part 7, and when operating a pump device, it is rotated to the use position. Preferably, the handle seating portion 7 is formed with a space 8 so as to easily rotate the handle 60 from the seated position to the use position with a finger.

Hereinafter, the coupling relationship between the components of the pump device 40 will be described with reference to FIGS. 4 and 8.

The first O-ring 77 is inserted into the O-ring inserting groove 57 of the plate portion 55. The first O-ring 77 has a size that is sufficiently accommodated in the O-ring inserting groove 57, the width of the first O-ring body 78 in the height direction is smaller than the width of the O-ring inserting groove (57). Moreover, the 1st O-ring protrusion 79 is formed in the 1st O-ring body 78 along the outer periphery. It is preferable that two O-ring protrusions 79 are formed. By inserting the first O-ring 77 into the O-ring insertion groove 57 of the plate portion 55, the plate portion 55 may reciprocate while maintaining airtightness along the inner wall of the body 42 of the cover 41. In order to facilitate the reciprocating motion, it is preferable that a lubricant is applied to the inner wall of the body 42 or the inner wall of the body 42 is made of an active material. Meanwhile, a second O-ring 73 is inserted into the second O-ring inserting portion 46 of the cover upper surface 44. The second O-ring 73 has a second O-ring groove 75 formed in the center along its outer circumferential surface of the body 74, and the second O-ring insert 46 is inserted into the groove 75, thereby providing a second O-ring groove. The o-ring 73 is attached to the cover upper surface 44. As a result, the central rod 51 of the rod part 50 may reciprocate while maintaining airtightness across the central hole 45 of the upper surface of the cover 44 up and down, and foreign matters may be removed from the central hole ( 45) can be prevented from entering into the cover. The second O-ring 73 is preferably formed with a thin O-ring protrusion 76 in contact with the outer surface of the central rod 51 along the inner peripheral surface of the body (74). The O-ring protrusion 76 reduces the contact area between the outer surface of the center rod 51 and the inner circumferential surface of the second O-ring 73, thereby facilitating the reciprocating motion of the center rod 51 as well as the pump device ( The air in the cover 41 of the 40 can be easily discharged to the outside.

After the O-

rings

73 and 77 are inserted and the central rod 51 of the rod 50 is positioned so that the central rod end region 52 protrudes upward through the central hole 45 of the upper cover 44. When the handle 60 is coupled to the end region 52, the pump device 40 is completed (see Fig. 7).

The pump device 40 coupled as described above is inserted into the vacuum device mounting portion 10. As described above, the cover protrusion binding groove 15 is formed in the wall portion 12 of the vacuum device settled portion, and the cover 41 of the pump apparatus is inserted into the cover protrusion binding groove 15 in the outer wall of the body 42. Since the projection 43 is formed, the pump device 40 is easily fixed and fixed to the vacuum device mounting portion 10. On the other hand, the pump device 40, more specifically, the cover 41 of the pump device, the extension surface 48 and the vacuum device set-up portion 10 of the cover 41 so as to be hermetically fixed to the vacuum device set-up portion 10 The third O-ring 70 is inserted between the locking step 13 of the). The third o-ring 70 may have a form suitable for maintaining the above airtightness. For example, as shown in FIG. 5, when the third O-ring inserting groove 47 is formed between the outer surface of the cover body 42 and the extended surface 48, the body of the third O-ring 70. An o-ring protrusion 72 protruding upward to be inserted into the groove 47 is formed in the 71.

Next, the valve device 20 will be described.

The valve apparatus 20 is comprised from the valve seat part 21, the valve 35 which is settled in this valve seat part, and the valve cover 27 engaging with the valve seat part.

Referring to FIG. 3, the valve seat portion 21 constitutes a cylindrical wall 22 integrally formed with the bottom portion 17 of the vacuum chamber settled portion, and in fact a part of the bottom portion 17 of the vacuum chamber settled portion. It consists of a seat bottom 24. The outer surface of the cylindrical wall 22 is formed with a rim projection 23 as a coupling means with the valve cover 27 to be described later, the valve seat bottom 24 is the first air communicating with the interior of the container body 2 of the vacuum vessel Outflow hole 25 is formed.

4 and 8, the valve 35 is composed of an upper surface 36 and an inclined surface 37 extending downwardly inclined to a predetermined length along the upper surface circumference. The valve is formed of a flexible material. As shown, it is preferable that the valve protrusion 38 upwardly protruding is formed on the valve upper surface 36 and the reinforcement 39 is formed around the lower end of the inclined surface 37 of the valve. The reinforcement part 39 is formed so that the lower end part of the valve inclination surface 37 may be thicker than another part.

Referring to FIG. 4 and FIG. 6, which shows a bottom perspective view of the valve cover, the valve cover 27 includes a cover wall 28 and a cover upper surface 30, and an inner surface of the cover wall 28 is provided with a border protrusion ( A rim groove 29 is formed to engage with the 23 and a second air outlet hole 32 is formed in the upper surface of the cover 30. The valve cover 27 has a pressurizing means for acting to pressurize and fix the valve 35 to the valve seat 21, and in the illustrated embodiment, the above-mentioned valve projection 38 is used as the pressurizing means. It has a central groove 31 to be inserted.

The coupling relationship of the valve apparatus 20 is demonstrated. First, the valve seat 21 surrounds the first air outlet 25 of the valve seat bottom 24 while the lower end of the inclined surface 36 of the valve contacts the valve seat bottom 24. After being placed in, the valve cover 27 is attached to the valve seat 21 so that the projection 38 of the valve is inserted into the central groove 31 of the valve cover. In the illustrated embodiment, the valve seat 21 and the valve cover 27 are attached to each other by combining the edge groove 29 of the wall 28 of the valve cover with the edge protrusion 23 of the valve seat. Any method such as screwing may be used. When the valve cover 27 is engaged with the valve seat 21, the valve 35 is pressurized by the valve cover 27 to the valve seat 21 so that the lower end of the inclined surface 37 of the valve is lowered at the bottom of the valve seat. Tightly adhere to 24). As described above, when the reinforcing portion 39 is formed at the lower end of the inclined surface 37, this hermetic adhesion can be further strengthened. Pressurization of the valve 35 by the lid 27 is achieved by adjusting the dimensions of the height of the valve and the height of the space between the lid 27 and the valve seat 21, which are bound to the valve 35 by the lid top surface 30. The upper surface 36 of the valve is pressurized and the fixing may be obtained by the friction force between the upper surface of the cover 30 and the valve upper surface 36, but as shown in the projections 28 and the projection of the valve upper surface It is preferable that pressure and fixation are simultaneously achieved by the central groove 31 of the valve cover to be inserted. Contrary to the embodiment illustrated by another pressing and securing means, a groove may be formed in the upper surface 36 of the valve and a protrusion may be formed in the upper surface 30 of the valve cover.

As described above, the vacuum apparatus 6 completes the valve apparatus 20 by placing the valve 35 in the valve seat portion 21 and the valve cover 27 in the valve seat portion 21. It is completed by hermetically coupling the pump device 40 assembled as described above to the vacuum device mounting portion 10.

Hereinafter, the operation of the vacuum apparatus 6 according to the present invention will be described with reference to FIG. 8.

FIG. 8 shows that the plate portion 55 of the rod portion is lowered by pushing the handle 60 downward to lower the rod portion 50 to operate the pump apparatus 40 constituting the vacuum apparatus 6. Shows a state in contact with the bottom 17 of the). In this state, the valve device 20 fixed to the bottom portion 17 of the vacuum device accommodation portion is located in the hollow portion 49 formed in the plate portion 55. Now, when pulling up the handle 60 to raise the rod portion 50, the plate portion 55 is moved upwardly away from the bottom portion 17 of the vacuum device receiving portion, held by the third O-ring 70 Due to the airtightness and the airtightness maintained by the first O-ring 77, a relative vacuum is formed in the space between the plate portion 55 and the bottom portion 17 of the vacuum device accommodating portion. Air in the container main body 2 rises through the 1st air outlet hole 25 by this vacuum, and the lower end part of the flexible valve inclined surface 37 which was in close contact with the bottom 24 of the valve seat part 21 at this time. The air is lifted out through the second air outlet 32 to the outside of the container body 2, that is, the space between the plate portion 55 and the bottom portion 17 of the vacuum device accommodation portion. Now, when the handle 60 is pushed downward and lowered again while the rod part 50 is raised, the space between the plate part 55 and the bottom part 17 of the vacuum apparatus accommodating part is in a relatively pressurized state. In such a pressurized state, the lower end of the flexible valve inclined surface 37 comes into close contact with the bottom 24 of the valve seat 21, and the adhesion increases as the pressing force increases, and a reinforcement part formed in the lower end of the valve inclined surface 37. (39) further enhances the pressure adhesion. Thus, air does not enter the container body 2 again through the valve device 20, but destroys the airtightness retained by the first O-ring 77, which is a relatively weak airtight portion, while the plate portion 55 and the cover top surface 44. Flow into the space between. That is, since the first O-ring 77 placed in the first O-ring insertion groove 57 of the plate portion 55 is in contact with the inner surface of the cover body 42 through the protrusion 79 of the first O-ring, the third O-ring ( Compared to 70), the airtight part is weaker, and moreover, since the first O-ring 77 is moving along the inner surface of the cover body 42, the airtightness is further lowered. As described above, the width in the height direction of the first O-ring body 78 is smaller than the width of the O-ring inserting groove 57, so that a gap is formed in the O-ring inserting groove 57, and the plate portion 55 rises and falls. During the movement, the first O-ring fuselage 78 may accommodate deformation of the O-ring fuselage 78 due to the up and down movement in the gap, and the upper groove 59 formed in the top plate 56 may include the first O-ring ( When the airtightness of 77) is broken, it serves to facilitate the movement of air. On the other hand, the air flowing into the space between the plate portion 55 and the cover upper surface 44 is directed to the second O-ring 73, which is a weaker airtight portion, when the rod portion 50 is raised to form a pressurized state in this space. It is discharged to the outside of the pump device 40 while destroying the airtight maintained. That is, since the projection 76 of the second O-ring 73 in contact with the outer surface of the center rod 51 is thin, the contact between the outer surface of the center rod 51 and the projection 76 of the second O-ring 73 is narrow. The area is smaller than the contact area between the projection 79 of the first O-ring and the inner surface of the cover body 42, and the rod portion 50 simultaneously moves relative to these O-

rings

77, 73, so that the second O-ring 73 While the airtightness between the projection 76 and the outer surface of the central rod 51 is destroyed, air is discharged to the outside of the pump device 40 through this portion. When sufficient vacuum is formed in the container main body 2, the handle 60 is axially rotated in the state which raised the rod part 50, and it is settled in the handle seat part 7 of the lid 3. As shown in FIG. In the present invention, since the handle 60 may be placed in the handle seating portion 7 of the lid 3 when not in use, a plurality of vacuum containers may be stacked and positioned to further improve the ease of use of the container.

The valve device acts to flow air in the container body 2 in one direction to the outside of the container body, which is obtained by the valve device 20 'described with reference to FIGS. 9 to 12 in addition to the valve device 20 described above. Can lose. Hereinafter, another embodiment of the valve device will be described.

The valve device 20 'is composed of a valve seat portion 81 and a valve 85.

The valve seat portion 81 is integrally formed on the bottom of the first seat surface 82 and the bottom of the bottom portion 17 of the vacuum device settle portion, which are integrally formed on the bottom surface 17 of the vacuum settlement portion 10. A valve seat hole 93 is formed in the center of the first and second seat surfaces 81 and 82 and penetrates them and communicates with the inside of the container body 2. In the illustrated embodiment, the plurality of valve seat protrusions of an arc shape in which the second seat surface 83 of the valve seat portion is discontinuously located along the valve seat hole 93 around the bottom portion 17 of the vacuum device settled portion. Is formed by the lower projection surface. When the second seat surface 83 is configured as described above, a gap 84 is created between the valve seat protrusions. In addition, in the illustrated embodiment, the valve seat accommodating groove 80 is formed to extend upward from the bottom of the vacuum device mounting portion 10 and the valve seat portion 81 is formed in the accommodating groove 80, This is to prevent the lower body of the valve 85 to be described later easily seen from the outside. In this case, the first sheet surface 82 is formed by the upper outer surface of the receiving groove 80. Unlike the illustrated embodiment, it is also possible not to form the receiving groove 80, in which case the bottom portion 17 of the vacuum device placement will constitute the first seat surface 82.

The valve 85 is composed of a cylindrical central body 86, an upper body 87 and a lower body 88 formed integrally with the upper and lower parts of the central body. The outer peripheral portion of the upper body 87 is formed with a first contact portion 89 in close contact with the first seat surface 82 of the valve seat portion, and the second seat surface 83 of the valve seat portion is formed on the valve lower body 88. And a second close contact portion 90 in close contact with each other. In the illustrated embodiment, the upper body 87 is formed of a first contact portion 89 in the form of a protrusion having a substantially closed arc cross section and extending along its outer circumference, and the lower body 88. The frustoconical shape has a lower surface of the frustocone to form a second contact portion 90, but the upper and lower bodies shown in the configuration is configured in reverse, or both the upper and lower fuselage in the upper fuselage shape or Both the upper body and the lower body may be configured as the lower body shape shown. On the other hand, the valve hollow part 92 is formed in the valve 85. The valve hollow portion 92 is formed over the lower body 88, the central body 86, and the upper body 87 of the valve as shown, but is formed to open below the lower body 88. The illustrated valve hollow portion 92 has a cylindrical shape, but may have any other shape. The central body 86 of the valve has a dimension whose diameter is smaller than the diameter of the valve seat hole 93.

Hereinafter, the coupling relationship between the valve 85 and the valve seat 81 and the operation of the valve device will be described with reference to FIG. 12.

In the valve 85, the first contact portion 89 of the upper fuselage is in close contact with the first seat surface 82 of the valve seat portion, and the second contact portion 90 of the lower fuselage is the second seat surface 83 of the valve seat portion. First, the valve lower body 88 is forcedly inserted into the valve seat hole 93 so as to be in close contact with the valve. Since the valve 85 is formed of a flexible material and the hollow portion 92 is formed over the valve body, the valve lower body 88 is deformed at the time of forced insertion, and easily passes through the valve seat hole 93. The state as shown in FIG. 12 is completed, and the valve apparatus 20 'is completed. In order to grip the valve 85 at the time of insertion, the valve upper body 87 is preferably formed with a valve protrusion 91 extending upward. When the valve 85 is coupled to the valve seat portion 81, as described above, a gap is formed between the valve seat hole and the central body outer surface because the diameter of the valve body 86 is smaller than the valve seat hole 93 diameter. This allows air to flow. When the second close contact portion 90 of the valve lower body is in close contact with the second seat surface 83 of the valve seat portion, the gap is in communication with the gap 84 between the second seat surfaces 83. The valve device 20 ′ may be located in the hollow part 49 formed in the plate part 55 of the rod part 50 of the pump device 40, as described in connection with the valve device 20. It must have a size.

Operation of the pump device 40 raises the rod part 50 of the pump device relative to the top of the valve device 20 ', ie the space between the plate portion 55 and the bottom 17 of the vacuum device receiving portion. When a vacuum is formed, the air in the container body 2 rises through the gap 84, the gap between the central body 86 of the valve in communication with the gap, wherein the first seat surface 82 of the valve seat portion And the first close contact portion 88 of the valve in close contact with each other, and air is discharged to the outside of the container body 2, that is, the space between the plate portion 55 and the bottom portion 17 of the vacuum device accommodation portion. On the other hand, when the rod portion 50 is lowered and the upper space of the valve device 20 'becomes pressurized, the first close contact portion 88 of the valve comes into close contact with the first seat surface 82 of the valve seat portion. The adhesion becomes larger as the pressing force is increased, so that air is prevented from entering the container body 2 again through the valve device 20 '. In this way, when the pump device 40 is operated, the valve device 20 ′ acts to flow the air in the container body 2 in one direction to the outside of the container body like the valve device 20.

If it is necessary to release the vacuum after the vacuum is generated in the vacuum container, the lid of the vacuum container may be forcibly separated from the container body, but it is preferable to provide a vacuum release device that can simply release the vacuum in the container. Do. Hereinafter, a vacuum releasing device used in the invention will be described with reference to FIGS. 13 to 15.

The vacuum releasing device 100 used in the present invention is preferably formed in the vacuum releasing device receiving groove 101 formed in the vacuum container lid (3). This is to improve the aesthetics of the container lid and also to prevent the vacuum release device 100 from being inadvertently operated.

The vacuum releasing device 100 is composed of a valve seat 105 and a valve 85 'formed integrally with the bottom 103 of the receiving groove 101, the basic configuration of the above-described valve device 20 Very similar to Therefore, redundant description is omitted.

The valve seat portion 105 has a first seat surface 106 in which a part of the bottom portion 103 of the vacuum release device receiving groove 101 serves, and a bottom surface 103 of the bottom of the vacuum release device receiving groove. A valve seat hole 109 is formed in the center of the first and second seat surfaces 106 and 107 having a second seat surface 107 integrally formed therein and communicating with the inside of the container body 2. In the illustrated embodiment, the second seat surface 107 of the valve seat portion 105 is discontinuously positioned along the periphery of the valve seat hole 109 at the bottom 103 of the bottom of the vacuum release device receiving groove. It is formed by the lower projection surface of the plurality of valve seat projections. When the second seat surface 107 is configured as described above, a gap 108 is created between the valve seat protrusions. In addition, in the illustrated embodiment, the groove 102 is formed by extending the wall of the vacuum release device accommodation groove 101, so that the lower body of the valve 85 ', which will be described later, is not easily seen from the outside. to be. Unlike the illustrated embodiment, the groove 102 may not be formed.

The valve 85 'has the same form and function as the valve 85 described above. Therefore, the detailed description thereof will be omitted, and in the following description, the components of the valve 85 'corresponding to the valve 85 use "'" in the reference numerals used in the description of the valve 85 (for example, For example, 87 ').

Since the coupling of the valve 85 'to the valve seat portion 105 is the same as that described in the valve device 20', detailed description thereof will be omitted. When the valve 85 'is coupled to the valve seat portion 105, the valve seat hole 109 and the central body 86' are similarly formed because the diameter of the central body 86 'of the valve is smaller than the diameter of the valve seat hole 109. A gap is formed between the outer surfaces to allow air to flow therethrough, and when the second contact portion 90 ′ of the valve lower body is in close contact with the second seat surface 107 of the valve seat portion, the gap is defined as a second. It is in communication with the gap 108 between the seat surfaces 107.

Since the pump device 40 is not attached to the upper portion of the vacuum releasing device 100, the valve 85 ′ of the vacuum releasing device does not act to flow air in the container body 2 in one direction to the outside of the container body. When a vacuum is generated in the vacuum chamber body 2, the first contact portion 89 ′ of the valve 85 ′ comes into close contact with the first seat surface 106 of the valve seat portion 105 and this adhesion The larger the vacuum force in (2) is, the larger the air force is, so that air is prevented from entering the container body 2 through the vacuum release device 100. When the vacuum release device 100 is to be operated to release the vacuum in the container body 2, as shown in Fig. 15, the valve protrusion 91 'of the valve 85' is crossed in the horizontal direction (arrow) with a finger. Direction). When this pressurization is applied, the flexible valve is bent in the transverse direction and the first contact portion 89 'in the valve seat portion, more precisely the first contact portion 89' in the direction pushed by the finger, left in the case of FIG. Direction first contact portion 89 'is separated from first seat surface 106, through which air passes through gaps and gaps 108 formed between the valve seat hole 109 and the outer surface of the central body 86'. Since the fluid flows into the container 2, the vacuum in the container 2 is dissipated.

If the user can know the degree of vacuum in the container, it will be very convenient as the degree of vacuum in the container can be increased when the degree of vacuum in the container is weakened over time. The present invention may further include a vacuum display device capable of simply displaying the relative degree of vacuum in the container. The following describes a vacuum display device for this purpose.

The perspective view of the vacuum container shown in FIGS. 1 and 2 and the bottom perspective view of the lid show not only the above-described vacuum device and vacuum release device but also a vacuum display device to be described later.

The corrugated pipe part 143 is made of an elastic material so that the corrugated pipe body itself is elastic, and the hollow part 144 (see Fig. 18) is formed therein. At one end of the corrugated pipe part 143, a vacuum indicator binding part 146 to which the vacuum indicator 148 is bound is formed. In the illustrated embodiment, the vacuum indicator binding portion 146 is in the form of a saddle formed between the corrugated pipe head 145 and the corrugated pipe body having an arrow shape so that the vacuum indicator 148 easily passes through the end of the corrugated pipe. Although the vacuum indicator 148 is formed, even if the reciprocating motion of the vacuum indicator 148 serves to prevent separation from the end of the corrugated pipe portion 143 may be any type of binding portion. For example, the head 145 is not formed at the end of the corrugated pipe portion, and the vacuum indicator 148 may be directly adhered to the end of the corrugated pipe portion 143 with an adhesive. In the illustrated embodiment, the corrugated pipe part 143 may have a substantially cylindrical shape, but may have a conical shape, but the hollow part 144 of the corrugated pipe part may have the other end of the corrugated pipe part, that is, the vacuum indicator 148 may have any shape. It should be configured to open to the opposite end of the side on which it is located.

The container part 133 includes a lower body 137, a plate body 134, and a stopper 140 on which the vacuum indicator 148 and the corrugated pipe part 143 are placed.

The lower body 137 is formed to have a space in which the corrugated pipe portion 143 to which the vacuum indicator 148 is attached can be settled. The lower body 137 is opened so that they can enter and exit, and the opening is sealed with a stopper 140. do. In addition, the lower body 137 is provided with a locking projection 138 to be inserted into the binding groove 128 of the settled portion of the vacuum display device to be described later.

The plate body 134 is formed integrally with the upper body of the lower body, and has a vent hole 149 and a vacuum display unit 132. The vent 149 serves to communicate the inside and outside air of the container portion 133. The vacuum display unit 132 is composed of a transparent window 135 showing the movement of the vacuum indicator 148 reciprocating according to the degree of vacuum in the vacuum container 1, and a scale 136 for displaying the degree of vacuum in the vacuum container. . In the illustrated embodiment, two scales indicating maximum vacuum and minimum vacuum are provided.

The stopper 140 serves to seal the opening of the lower body 137, and the protrusion 142 is inserted into the hollow portion 144 of the corrugated pipe portion so that the corrugated pipe portion 143 easily adheres to one side thereof. It is preferably formed. The stopper 140 has a connection hole 141 communicating with the hollow portion 144 of the corrugated pipe portion and the inside of the vacuum container.

Hereinafter, referring to FIG. 18, the coupling relationship between the components of the vacuum display device 130 and the operation thereof will be described.

First, in an ecology in which the vacuum indicator 148 binds to the vacuum indicator binding part 146 of the corrugation pipe part 143, the corrugation pipe part 143 is opened through the opening of the lower body 137 of the container part 133. Push it into the lower fuselage. Next, when the stopper 140 is sealed, the other end of the corrugated pipe part 143, that is, the opposite end of the side where the vacuum indicator 148 is located is in close contact with the stopper. In the case of close contact, the hollow portion 144 of the corrugated pipe portion is in communication with the connection hole 142 of the stopper, but not in communication with the internal space of the container portion 133, the corrugated pipe portion 143 is made of an elastic material Because it is configured, it is possible to freely stretch the material movement in the container portion 133. In this state, when a vacuum is generated inside the vacuum container 1, the vacuum is transmitted to the hollow portion 144 of the corrugated pipe portion through the connection hole 142 of the stopper. On the other hand, the inner space of the container portion 133 communicates with the outside atmosphere through the air vent 149, but is separated from the hollow portion 144 of the corrugated pipe portion, the inner space of the container portion 133 maintains the atmospheric pressure state. Therefore, the corrugated pipe part 143 is contracted by atmospheric pressure, and the degree of shrinkage will be proportional to the degree of vacuum inside the vacuum container 1. If the vacuum in the vacuum container 1 is released, since both the inner space of the container portion 133 and the hollow portion 144 inside the corrugated pipe portion are at atmospheric pressure, the corrugated pipe portion 143 returns to its original state. Shrinkage and return of the corrugated pipe 143 is represented by a vacuum indicator 148 attached to one end of the corrugated pipe 143, which can be seen through the transparent window 135 of the plate body 132. . The degree of vacuum can be ascertained by the position of the vacuum indicator 148 relative to the scale 136. The vacuum indicator 148 is preferably colored, for example, in red so that the movement can be clearly seen through the transparent window 135.

The above-described vacuum display device 130 is mounted on the vacuum display device settled portion 121 of the vacuum container lid 3, which will be described below.

The vacuum display device mounting portion 121 is formed in the shape of a groove extending downward from the container lid 3 so as to have a space in which the container portion 133 of the vacuum display device 130 is accommodated. In the settling portion 121, a binding groove into which the locking jaw portion 124 on which the lower side portion of the plate-shaped body 132 of the vacuum display device container is mounted and the locking projection 138 formed on the lower body 137 of the container portion are inserted. 128 is formed. Accordingly, when the vacuum display device 130 is pushed into the settled portion 121, the lower side portion 139 of the plate-shaped body 132 of the vacuum display device container portion is seated on the locking jaw portion 124 and the lower body 137 is disposed. The locking protrusion 138 is inserted into the binding groove 128 so that the vacuum display device 130 is in close contact with the settled portion 121. In this case, the sealing member 131 may be positioned at the latching jaw portion 124 of the settling portion so that the vacuum display device 130 is seated in the airtight state of the settling portion 121. In addition, a connection groove 127 (see FIG. 2) communicating with the connection hole 141 of the vacuum display device stopper 140 and the inside of the vacuum container is formed in the direction of the connection hole 141 in the vacuum display device setter 121. It is preferable to facilitate communication between the inside of the vacuum container and the hollow portion 144 of the corrugated pipe portion of the vacuum display device.
