DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kind of vacuum vessel having a function of displaying a vacuum state, and more particularly to displaying a degree of vacuum so that a user can accurately grasp the degree of vacuum of the vacuum vessel and a display unit having a lid. The present invention relates to a structure of a vacuum container that can place articles on a lid without protruding more.

[0002]

2. Description of the Related Art Known vacuum containers are used for preserving food, and the inside of the vacuum container is evacuated and evacuated to extend the shelf life of the food and reduce spoilage of the food. The well-known vacuum container shown in FIG. 1 is composed of one container 10a and one lid 11a. The lid 11a can cover an upper end opening of the container 10a, can seal the container 10a, and 1
One display button 12a and one pressure-leakage button 13a are provided on the upper part of 1a, and one suction handle 14a is provided on the side wall of the lid 11a.
A piston (not shown) inside the lid 11a is controlled by a reciprocating pull operation to extract air inside the container 10a, gradually create a vacuum state inside the container 10a, and display a degree of vacuum inside the container 10a. The display is made according to the height of 12a. When it is desired to open the lid 11a, the lid 11a can be opened by pressing the pressure leak button 13a to restore the inside of the container 10a to the normal pressure. Also, one time table 15a is provided on the top of the lid 11a so that the date on which the product is placed can be displayed.

[0003] However, in the above-mentioned known vacuum vessel, the display button 12a protrudes from the upper portion of the lid 11a, so that articles cannot be placed on the lid 11a, and the user cannot display the display button 12a. Since the degree of vacuum is determined based on the height of the vacuum vessel, the error is relatively large, and the degree of vacuum in the vacuum vessel cannot be accurately grasped. Further, when the user extracts the air in the container 10a with the suction handle 14a, the user must hold the container 10a or the lid 11a with one hand and reciprocate the suction handle 14a with the other hand. Above was inconvenient. In addition, since the time table 15a is provided on the upper portion of the lid 11a, when the vacuum container is placed at a high place, the time table 15a cannot be seen, and it takes time and effort to remove the vacuum container from the high place. Since the time table 15a cannot be seen unless the user lowers the time, the user is inconvenienced.

[0004] As described above, the known vacuum vessel has inconveniences and disadvantages in practical use, and there is a need for improvement.

Separately, a plurality of corresponding cylinders 33 are fixed to the base sheet 20, the pistons 32 are combined into the corresponding cylinders 33, an exhaust hole 34 is appropriately provided at a lower end of the cylinders 33, and one cylinder 33 is separately provided in each of the cylinders 33. A check valve 35 is provided to allow air to flow upward only, and elastic means 36 is provided between the suction button 30 and the base sheet 20 as appropriate and the suction button 30 is provided.
Provides the power to recover upwards. When the suction button 30 is pressed downward (see FIG. 8), the piston rod 3
1 and the piston 32 move downward in conjunction with each other, and at this time, the check valve 35 seals the exhaust hole 34, the air in the cylinder 33 flows only upward, and the force on the suction button 30 is released. The suction button 30 recovers upward when pressed by the elastic means 36, and the piston rod 31 and the piston 32 also move upward in conjunction with the suction button 30. At this time, the check valve 35 opens the exhaust hole 34 to draw the air in the container 1 into the cylinder 33, and thus the air in the container 1 is extracted in one direction by the reciprocating pressing of the suction button 30, so that the air in the container 1 is extracted. Can be gradually evacuated.

The display unit 23 has one telescopic cylinder 3
7 (see FIG. 9), one end of the telescopic cylinder 37 is connected to the base sheet 20 and
The telescopic cylinder 37 communicates with the inside of the container 1 through the perforations 38, and one rack 3 is provided at the other end of the telescopic cylinder 37.

Is locked. When the inside of the container 1 is evacuated and evacuated to generate a suction force, the telescopic cylinder 37 contracts (see FIG. 10), and the rack 39 is moved, and the rack 39 is transmitted to the gear 40 to rotate the gear 40. Then, the pointer 41 connected to the gear 40 is operated, and the degree of vacuum inside the container 1 is indicated by the corresponding scale 43.

The pressure-releasing unit 24 is installed between the base sheet 20 and the upper lid 21 and has a pressure-releasing button 44 and a pressure-releasing valve 45, and the pressure-releasing button 44 is slidably combined with the side wall of the upper lid 21. The interlocking means 46 is connected to the inside of the leak button 44, and the leak valve 45 is combined into one leak chamber 26, the leak chamber 26 is fixed to the base sheet 20, and the pressure is leaked into the leak chamber 26. A hole 47 is provided (see FIGS. 11 and 12), the leak hole 47 communicates with the inside of the container 1, and another elastic means 48 is separately provided between the leak chamber 26 and the interlocking means 46. Means 48 is a pressure relief valve 45
Can be pressed to close the leak hole 47 (see FIG. 11). When the leak button 44 is driven, the interlocking means 46 pushes the leak valve 45, and the leak valve 45 is closed. 47 is opened (FIG. 12), and the inside of the container 1 is restored to the normal pressure.

The time table 25 includes date numbers 49 and 50 of the date of the month, which are installed on the side walls of the base sheet 20 and the upper cover 21 and slide rails 51 and 52 are provided above and below the date numbers 49 and 50, respectively. And two indicator means 53, 54 slidably mounted on slide rails 51, 52.
And these two indicating means 53, 54 are slid freely on the slide rails 51, 52 so that the user can select and instruct certain date numbers 49, 50, and the food is placed. The date is displayed. Thus, one vacuum container is formed.

[0016]

According to the present invention, the display unit 23 includes the pointer 41.
The degree of vacuum in the container 1 is displayed in a form in which the scale 43 is instructed, and the pointer 41 is set in the recess 29 of the upper lid 21 so as not to protrude from the upper lid 21. Articles can be placed and the user can use guideline 4.
The degree of vacuum can be known from the scale 43 shown in FIG.
It is not necessary to judge by the visual measurement method, the error can be greatly reduced, and the user can accurately grasp the degree of vacuum of the vacuum container.

Further, when the user presses the suction button 30 of the suction unit 22 to extract the air inside the container 1, there is no need to hold the container 1 or the lid 2 with one hand,
