The present invention relates to a vacuum packaging paper sealing device in which the vacuum packaging paper is stored after being vacuumed without being heat sealed.

In general, a vacuum packaging paper is a packaging paper used to store food in a vacuum state after the food or the like is stored therein.

Conventionally, in the vacuum packaging, as shown in Fig. 1, a conventional vacuum packaging machine of Utility Model Registration No. 20-0235323 and the name of the device described in "Vacuum and Adhesive Packaging Machine" was used.

The vacuum packaging machine as shown in Figure 1, the upper and lower cases (10, 20), and the rubber packing (23, 24) and then packing one end of the vacuum packaging paper 30 is inserted into the upper and lower cases (10, 20), Heating means for sealing the vacuum pump 25 and the vacuum wrapping paper 30 on the front surface of the lower rubber packing 23 so as to suck the air inside the vacuum wrapping paper 30 by the upper and lower rubber packings 23 and 24. It is comprised including the phosphorus heater 21.

Referring to the vacuum packaging process by the vacuum packaging machine as follows.

First, foodstuffs and the like are stored in the vacuum packaging paper 30, and after the opening of the vacuum wrapping paper 30 is positioned between the upper and lower rubber packings 23 and 24, the upper and lower rubber packings 23 and 24 are engaged. The upper case 20 is lowered above the lower case 10.

After that, when a predetermined switch is operated, the vacuum pump 25 is operated. In accordance with the operation of the vacuum pump 25, a vacuum is formed in the space between the rubber packings 23 and 24, and the inside of the vacuum packaging paper is also vacuumed. do. At this time, since the embossing 32a is formed on one inner surface of the vacuum wrapping paper 30, the air inside the vacuum wrapping paper 30 is well sucked by the embossing 32a.

When the vacuum of the vacuum packaging paper is completed as described above, the vacuum packaging paper is heat-sealed and sealed by the heater 21, and the upper case is opened to cut and store the vacuum and heat-sealed vacuum packaging paper.

However, the vacuum packaging machine as described above has a problem in that its configuration is complicated, including a heating means, and it is difficult to recycle since the vacuum packaging paper must be heat-sealed and cut.

Thus, the inventor has invented a vacuum chamber device that can be stored together after vacuum sealing the vacuum wrapping paper by a simple configuration, such as Korean Utility Model Registration No. 3162416. As shown in FIG. 2, the vacuum chamber device includes an upper case 120, a lower case 130, a vacuum chamber 140, a packing 150, and a vacuum valve 170.

In FIG. 2, the flexible hose nozzle 160 serves as an embossing for the vacuum wrapping paper 90, especially the vacuum wrapping paper in which the embossing is not formed on the inner surface, so as to form an air passage in the vacuum wrapping paper so that the vacuum is good. will be. In addition, the clasp 181 and the locking piece 182 as side locking means formed on both the left and right sides of the vacuum chamber device are for maintaining the upper case 120 and the lower case 130 in a closed state.

Fig. 3 shows the vacuum packing by the vacuum chamber device as shown in Fig. 2. As shown in the drawing, one end of the vacuum wrapping paper 190 is positioned to surround the hose nozzle 160 and protrude into the vacuum chamber 140. At this time, the other end portion of the vacuum wrapping paper 190 is located outside the vacuum chamber 40 as it is. Next, the upper case 120 is closed above the lower case 130, and the vacuum chamber 140 is sealed by the packing 150.

After the upper case 120 is closed, the vacuum valve 170 is connected to the vacuum pump 191 through the hose 192, and the inside of the vacuum packaging paper 190 and the vacuum chamber 140 according to the operation of the vacuum pump 191. ) Is vacuumed. After the predetermined degree of vacuum is achieved, the hose 192 and the vacuum pump 191 are separated, and the vacuum valve 170 is closed.

Then, the clasp 181 of the locking means 180 is coupled to the locking piece 182, the upper case 120 is maintained in a closed position in the lower case 130, accordingly the vacuum packaging of the vacuum wrapping paper 190 The task is complete. In this state, the vacuum wrapping paper 190 and the vacuum chamber device are stored together.

The present invention is a vacuum chamber device that can be stored together after vacuum sealing the vacuum packaging as described above, in particular a vacuum chamber to form a locking means to maintain the upper case and the lower case in a closed state on the front side The purpose is to provide a device.

In the vacuum chamber device, the locking means serves to maintain the upper case in the closed state by the lower case, thereby preventing the upper case from being separated from the lower case due to an external environment or the like to maintain the vacuum state in the vacuum chamber. This allows the vacuum to be maintained without being released without special care in long term storage.

In addition, such a locking means may help to ensure that the vacuum is made smoothly during the vacuum because the upper case and the lower case can be in close contact with the vacuum chamber can be sealed.

However, when only the side locking means formed on both the left and right sides of the vacuum chamber device as shown in Figure 2, the locking force is not properly transmitted to the central portion, there is a problem that the locking of the central portion is weak. However, when the upper and lower cases are hinged at the rear as shown in FIG. 2, the locking role can be achieved by the hinge, so that the problem of weak locking at the rear side may be solved to some extent.

However, it is difficult to provide the proper locking means due to the interference because the front portion where the vacuum wrapping paper is to be held must be held. Therefore, there is a need for a locking means capable of keeping the upper case strongly closed in the lower case, as well as in the center, particularly in front of the left and right sides.

Vacuum chamber device according to the present invention, the upper case; A lower case; A vacuum chamber in which the upper case and the lower case are formed to be in contact with each other, the opening of the vacuum packing paper is exposed to the inside, and the other end of the vacuum packing paper is located outside; A vacuum valve installed at one side of the upper case or the lower case to open and close an air outlet passage through the vacuum chamber; A locking means formed on the upper case or the lower case to maintain the upper and lower cases in a closed state; It is configured to include, wherein either side of the upper case or the lower case is formed with a vacuum wrapping paper insertion portion formed with a vacuum wrapping paper insertion passage to pass through the opening of the vacuum wrapping paper, the locking means in particular on the vacuum wrapping paper insertion side Including an insertion part side locking means formed; It features.

Due to the insertion-side locking means 202 and 203, the locking state at the portion where the vacuum packaging insert 200 is formed in the vacuum chamber device is maintained firmly.

The insertion part side locking means 202, 203 may be in any form as long as it is suitable for the purpose of the present invention, for example, may be the same as the shape of the side locking means 181, 182 shown in FIG. However, as shown in FIGS. 4 to 6, it is preferable to configure the upper catching portion 202 integrally formed in the upper case 120 and the lower catching portion 203 integrally formed in the lower case 130. In addition, the upper locking portion 202 and the lower locking portion 203 may be formed continuously over the length of the vacuum wrapping paper insertion passage 201 as shown in FIG. As a result, the locking of the entire portion of the conventional vacuum wrapping paper 190 is inserted firmly, so that the airtightness of the vacuum chamber 140 may be maintained firmly.

As shown in the drawing, the upper catching portion 202 and the lower catching portion 203 are formed with an upper catching jaw 204 and a lower catching jaw 205, respectively. The lower locking jaw 205 is locked to each other is made.

More preferably, the upper locking portion 202 is formed in the form of a V-shaped clip, as shown in Figures 4 to 6, the lower locking portion 203 is the upper locking portion of the V-shaped clip like this It is preferable to form the groove shape that can accommodate the 202. Therefore, the upper case 120 is placed on the lower case 130 (in this state, the vacuum chamber 140 may be in a sealed state by packing) and vacuum the vacuum chamber 140 and the external atmospheric pressure and As the upper case 120 is automatically compressed to the lower case 130 by the pressure difference in the vacuum chamber 140, the upper catching jaw 204 of the upper catching portion 202 is formed of the lower catching portion 203. The lower locking part 203 may be caught and locked. Therefore, the lock may be automatically performed in the process of vacuuming the vacuum chamber 140 even without artificially operating the locking means. In addition, the locking means in the form of a clip has the advantage that it is convenient to unlock the lock.

As in the vacuum chamber device shown in Fig. 4, if the vacuum wrapping paper inserting portion 200 having the vacuum wrapping paper inserting passage 201 is formed, and the inserting means side locking means 202 and 203 are included as the locking means, the vacuum chamber 140 Confidentiality can be maintained.
