The present invention relates to a vacuum container having a protective cap for the check valve, and more particularly, through a protective cap covering the check valve provided in the cover of the vacuum container to prevent the check valve from opening when not desired and opening of the cover. The present invention relates to a vacuum container to facilitate an operation of supplying air into a container.

The vacuum container can be evacuated by releasing the air inside the container to reduce the temperature change in the container, thereby extending the shelf life of the contents of the food, fruit, and vegetables contained in the container and maintaining freshness. Due to the increase in the binding force between the lid and the container body is not easy to open the lid because the contents contained in the container has been spotlighted recently.

The development of conventional vacuum vessels has focused on how efficiently and simply to evacuate the interior of the vessel.

According to the air pumping method, the vacuum container may be classified into a method using a container cover and a method using a pump.

The former is to cover the body of the container and open the check valve to press the cover toward the bottom of the container to discharge the air inside the container and to close the check valve, for example, Korean Utility Model Registration No. 0253320 ( 2001.10.26) Food containers that can be easily opened and closed, and Utility Model Registration No. 0269043 (2002.03.08) Food containers having a wheat / opening valve structure.

In the latter case, when the pump inlet is in close contact with the container cover and operated, the check valve is opened and the vacuum is made. For example, Korean Utility Model Registration No. 0201222 (2000.10.05) `` Valve device of vacuum vessel '' and utility model registration 0255744 (Nov. 16, 2001), Vacuum Packaging Containers.

However, conventional vacuum containers are focused only on evacuating the container, and the user opens the check valve with a fingernail to open the container and the problem that the check valve is inadvertently opened while storing and moving the vacuum container. Because it must be, it cannot be opened easily, so it is not considered uncomfortable and injured.

In some cases, a lever is attached to the check valve to facilitate opening of the check valve, but the risk of opening the container at an undesired moment during movement and storage due to the lever is further increased.

The present invention has been proposed in order to solve the problems of the conventional vacuum containers described above when the container storage, movement and check valve opening, the present invention is a protective cap that can solve the problem that the check valve is opened at an undesired moment vacuum container The purpose is to introduce.

Another object of the present invention is to provide a coupling structure of a check valve, a lever and a protective cap that can easily open the check valve.

In addition, an object of the present invention is to provide a sliding means and a position fixing means that can ensure the operation reliability of the opening and closing for the check valve.

Vacuum container provided with a protective cap for the check valve according to the present invention to achieve the above object; A cover having a packing ring at an edge contacting the main body; A check valve inserted into an insertion part of the cover; A lever coupled to an upper portion of the check valve; A protective cap positioned on the cover to cover the check valve; And provided in the protective cap, it comprises an opening and closing opening for opening the check valve by pressing the lever.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote members having the same function.

1 and 2A, the vacuum container according to the present invention includes a main body 1, a lid 10 having a packing ring (not shown) on an edge contacting the main body 1, and the lid 10. The check valve 20 is positioned in the), the lever 30 is coupled to the upper check valve, the protective cap 40 covering the check valve, and is coupled to slide to the protective cap to press the lever 30 And an opening and closing port 50 for opening the check valve 20.

The main body 1 is provided with fixing means 17 for fixing the cover 20. The material and structure of these fixing means can be modified in various ways, such as those used in general side dishes.

Referring to Figure 3a and Figure 3b, the protective cap 40 of the present invention to facilitate the mold design and to facilitate the assembly of the protective cap 40 and the opening 50, the outer cap 41 and the inner cap 43 Is done.

The outer cap 41 and the inner cap 43 is provided with a position fixing means so that the rectangular cutouts 41a and 43a for the exposure of the opening and closing opening 50 and the grip portion 57 can be easily matched with each other. It is. The position fixing means shown is a projection 41b formed on the inner bottom surface of the outer cap 41 and a groove 43b formed in the inner cap 43 so that the projection 41b is fitted. However, instead of the protrusion 41b and the groove 43b, the position fixing means may be embodied in such a manner that the outer cap and the inner cap have an angled or bent correspondingly to each other to engage and engage.

In addition, the outer cap 41 is symmetrically formed with two tungsten pieces 42, the inner edge of the bottom surface of the tungsten piece 42 is fine and protrusions (not shown) are formed so that the inner cap 43 When combined with the inner cap and the outer cap is not to be easily separated.

In addition, a protrusion 42a is formed at an outer side of the tungsten piece 42, and a groove corresponding to the protrusion 42a is formed at the cap insertion portion 13 (see FIG. 2B) of the lid 10. It is formed so as to limit the engagement position of the outer cap 41 and the lid 20. Due to this, the assembly operation can be easily performed, and the separation preventing means of the lever 30 coupled with the check valve 20 can be easily combined with each other in the correct position as described below.

3A and 3B, the structure of the inner cap 43 will be described. The inner cap 43 is a slide in which the sliding protrusion 55 of the opening and closing port 50 is coupled to both bottom surfaces of the cutout 43a. The groove 45 is formed. Optionally, the slide groove is formed in the opening and closing and the sliding protrusion may be formed in the inner cap.

In addition, a stopper is provided at a predetermined position around the cutout 43 of the inner cap 43 and the contact surface of the opening and closing port 50, so that the opening and closing port 50 that slides opens the check valve 20 or It would be good for the opening and closing function to be stable to be fixed at the closing position.

The stop means shown is a stop groove 47a (see FIG. 3A) formed in the inner cap 43, and a stop protrusion 53a formed below the right sliding protrusion 55 of the opening / closing device 50 (see FIG. 3A). 3b). The stopper 53a of the opening and closing port 50 receives elasticity from the finger piece 53. And since the stop groove 47a of the inner cap is formed by the protrusion 47b rather than the recessed shape, the stop piece 53 does not exert elasticity when the opening / closing device 50 is slid. The elasticity is exerted by pushing the grip piece 53 inward by the force pushing the grip portion 57 of the opening and closing port 50 at the moment of contact with the protrusion 53a and the protrusion 47b of the inner cap 43. . Therefore, the tungsten piece 53 is not easily fatigued and can be used for a long time. The stopper 53a is pressed by the stop piece 47a of the inner cap 43 while making a click sound.

Although the illustrated stop groove 47a is formed in only one position, two positions of the inner cap 43, that is, the opening and closing port 50, pressurizes the lever 30 to open the check valve 20 as necessary. Position and the position where the lever 30 is not pressurized so that the check valve does not open at an undesired moment.

On the other hand, the inner cap 43 is formed with a separation preventing means for actuating the lever 30 in a fixed position. That is, in FIG. 3B, recessed grooves 33a and 33b are formed at both sides of the lever 30, and the bottom portion of the inner cap 43 is fitted at a position corresponding to the recessed grooves 33a and 33b of the lever. The projections 43c and 43d are formed. Therefore, the check valve 20 is lifted in the process of evacuating the container as shown in FIG. 4 or injecting air into the container to open the cover as shown in FIG. 6, even if the lever 30 is moved. The means 33a, 33b 43c, 43d remain in place.

As described above, the outer cap is assembled at the cover and in position due to the projections 42a formed on the carbon element piece 42 of the outer cap 41 during the assembly process during the production of the vacuum container, thereby fitting the protective cap 40. Aligning the projections 43c and 43d with the inlet grooves 33a and 33b of the lever 30 corresponds to the assembling position of the outer cap 41 when the lever 30 and the check valve 20 are engaged. This can be done easily by staying in a certain direction.

In FIG. 3A, the check valve 20 used in the present invention is made of a soft synthetic resin such as silicon, and is connected to the insertion part 25 located at the insertion part 15 (see FIG. 2B) of the cover 10. The upper disk 21 and the lower disk 23 which are formed in the both ends of are formed. In addition to obtaining the elasticity necessary for the valve function from the material as shown in the illustrated form, the check valve can also be used a known check valve which obtains the elasticity from the spring. In order to open and close the air passage, the upper disc 21 is larger in diameter than the lower disc 23 and larger than the diameter of the air passage in which the connection portion 25 is located.

On the other hand, the upper part of the check valve 20 is formed with a means for coupling the lever 30, which is the fitting portion 29 and the release preventing plate 27 coupled to the insertion groove 31 of the lever 30. Consists of

Referring to Figure 3a, 3b and 2b will be described the assembling process of the check valve 20, the lever 30, the protective cap 40 and the opening and closing port 50 having the structure as described above as follows.

First, in FIGS. 3A and 3B, the sliding protrusion 55 of the opening and closing port 50 is coupled to the sliding groove 45 of the inner cap 43. Subsequently, the inner cap 43 and the outer cap 41 are coupled to the groove 43b as the position fixing means and the protrusion 41b to coincide. At this time, the inner cap 43 is not easily separated due to the lower protrusion (not shown) of the finger piece 42 of the outer cap 41.

Next, in FIG. 2B, the check valve 20 is inserted into the check valve insertion part 15 of the cover 10, and the insertion groove 31 of the lever 30 is inserted into the fitting part 29 of the check valve. Combine.

Subsequently, in the state in which the lever 30 is set in place, the protrusion 42 of the outer cap 41 and the groove 42 (not shown) formed on the inner circumferential surface of the insertion part 13 of the cover 10 are engaged. . At this time, the fitting projections (43c, 43d) of the inner cap 43 is a separation prevention means is coupled to the recessed grooves (33a, 33b) of the lever (30).

When the assembly is completed, the adhesive can be attached to the protective cap 40 and the cover 10.

7A and 7B show an alternative form of the protective cap and check valve opening and closing of the vacuum container described above.

The illustrated protective cap 141 is similar in overall shape to the outer cap 41 shown in Figure 3a, and also provided with a finger piece (reference numeral 42 in Figure 3a) for coupling with the cover 110 have.

7A has a main body 151 having an outer circumferential surface in contact with an inner circumferential surface of the protective cap 141, and a central through hole 141a of the protective cap 141. It is composed of a pressing portion 153 is inserted into the), and the elastic means 155 accommodated in the inner peripheral surface of the opening and closing hole 150, the main body 151.

The check valve 120 and the lever 130 have the same structure as those shown in FIG. 3A (20, 30).

In FIG. 7B, the protective cap 141 and the main body 151 of the opening and closing hole 150 are mounted to the installation portion of the cover 110. When vacuuming the inside of the vacuum container or introducing air into the vacuum container, the air is a gap between the protective cap 141 through hole 141a and the pressurizing portion 153 of the opening and closing hole 150 and the protective cap 141. ) And the gap 144 between the opening and closing body 151, and through the passage connecting the through-hole of the installation of the check valve 120. If necessary, an appropriate air communication path may be formed in the opening and closing hole 150 to smoothly flow in and out.

In FIG. 7B, when the check valve 120 is opened, the pressing portion 153 of the opening and closing port 150 is pressed to compress the elastic means 155, and the lower surface of the pressing portion 153 presses the lever 130. Accordingly, the upper disk of the check valve 120 is lifted and air is introduced into the vacuum container.

The opening of the check valve at an undesired moment in the opening and closing of this type can be achieved to some extent by the protective cap 151, but it is not intended, but the lever 130 is pressed by the pressing unit 153, the check valve 120 Several measures can be taken to prevent the opening of). The simplest form is such that the height of the upper portion of the pressing portion 153 in the non-pressing state of the opening 150 is the same or slightly lower than the upper height of the protective cap 141. Another method is to use the elastic means 155 having a strong elastic force.

Referring to Figures 4 to 6 the operation and effects of the vacuum vessel of the present invention described above are as follows.

First, Figure 4 is a cross-sectional view associated with the vacuumization of the container by using the pump (P), by sliding the grip portion 57 of the opening and closing port 50 by sliding the pressing portion 51 does not contact the lever 30 The opening and closing port stays in the container, and the inlet of the pump P is brought into close contact with the seating groove 11 of the cover 10. At this time, the position of the opening and closing port 50 may be fixed by the fixing means.

The illustrated pump P has a shape similar to a syringe, and when the pump P inlet is brought into contact with the seating groove 11 of the cover 10 for evacuation, the piston P1 should be positioned below. When the piston P1 is pulled out, the suction force acts through the cutout portions 41a and 43a of the outer cap 41 and the inner cap 43 which are not blocked by the opening / closing opening 50 by the suction force. As the upper disk 21 of 20 is opened, the air inside the container body is discharged (not shown) of the check valve insert 15 of the lid 10 located around the lower disk 23 and the valve 20. ) Is sucked into the pump P through a passage (where the diameter of the cross section of the passage is larger than the diameter of the cross section of the connecting portion), whereby the vessel is somewhat vacuumed. When using a pump operated by a power means such as a compressor, the degree of vacuum can be made larger.

On the other hand, the protective cap 40 and the opening and closing port 50 according to the present invention can be used in a vacuum vessel for vacuuming using the cover itself of the container without using a mechanism. In this case, as shown in FIG. 6, the lever 30 is bent by the pressing part 51 so that the check valve 20 is opened by pushing the opening and closing port 50 to the left side, and then pressing the cover having elasticity to press the container body. After allowing the air inside to escape, vacuuming is performed in such a way that the check valve is closed by pushing the opening / closing opening to the right again.

Subsequently, in FIG. 5, when the vacuum by the pump P is finished and the pump P is separated from the lid 10, the upper disc 21 of the check valve 20 closes the passage of the lid.

When opening the container in such a state, as shown in Figure 6, by pushing the opening and closing port 50 to the left side so that the pressing portion 51 presses the lever 30 so that the upper disk 21 of the check valve 20 is lifted. Allow air to enter the container.

In addition to preventing the protective cap from covering the check valve to prevent the check valve 20 from opening at an undesired moment in the form of the protective cap 40 and the opening and closing port 50 shown in FIG. May be introduced at an unintentional moment to pressurize the lever 30 to prevent the check valve from opening. For example, the upper height of the grip portion 57 of the opening and closing port 50 is equal to the upper height of the outer cap 41, or the protruding degree of the stop means 47a, 47b, 53, 53a described above. And elasticity may be increased.

As described above, the vacuum container provided with the protective cap for the check valve according to the present invention can solve the problem of opening the check valve at an undesired moment through the protective cap, and easily opening the check valve through the opening and closing port. can do.

In addition, the present invention is easy to mold design because the protective cap is separated into the inner cap and the outer cap, the assembly structure of the outer cap of the inner cap and the various position fixing means is easy to assemble the opening and closing the protective cap, It is possible to ensure the reliability of the operation through the sliding means for the stop means and the release prevention means for the lever.

In the above description of the present invention with reference to the accompanying drawings, the protective cap and the opening and closing having a specific shape and structure have been described mainly with respect to the present invention can be variously modified and changed by those skilled in the art, such modifications and changes are the protection of the present invention Should be interpreted as being within the scope.
