Description

Vacuum sealed container {AIRTIGHT CONTAINER}

The present invention relates to a vacuum sealed container.

The vacuum sealed container can store food in a state where the container is deflated, so that food can be stored longer than a normal sealed container.

Such a vacuum sealed container is a vacuum sealed container disclosed in Korea Patent Publication No. 10-2008-0014536. (Hereinafter referred to as "conventional vacuum sealing container")

The present applicant, as a user using a conventional vacuum sealed container, invented the present invention to solve various problems occurred while using the conventional vacuum sealed container.

1 is a view showing a conventional vacuum sealing container.

With reference to FIG. 1, various problems which occur while using the conventional vacuum sealing container 1 are demonstrated.

First, in order to wash the lid body 20, the packing 40 must be separated from the lid body 20. After the lid body 20 is cleaned, the press fitting protrusion 42-1 of the packing 40 is placed in the packing mounting groove 28-1 of the lid body 20, and the packing 40 is pressed to press the packing mounting groove ( 28-1), the indentation protrusion 42-1 should be inserted in the vertical direction.

At this time, if the user does not press the packing 40 along the packing mounting groove 28-1 with a uniform force, the depth at which the press-fit protrusion 42-1 is inserted into the packing mounting groove 29-1 has a packing mounting groove. The packing 40 is wrinkled by varying along 28-1. When the packing 40 is corrugated, a gap is formed between the inlet 12 of the container body 10 and the contact part 44 of the packing 40. Through such a gap, the outside air penetrates into the container body 10, causing food to spoil.

Therefore, when mounting the packing 40 to the lid body 20, the user should be careful to press the indentation protrusion 42-1 along the packing mounting groove 28-1 with a uniform force. This is difficult and inconvenient for the user.

Second, since the inlet 12 of the container body 10 is curved, the inlet 12 and the close contact 44 is in line contact. Therefore, even if the coupling position of the container body 10 and the lid body 20 is slightly twisted, a gap may occur between the inlet portion 12 and the contact portion 44. Through such a gap, the outside air penetrates into the container body 10, causing food to spoil.

Third, the hemispherical part 36a-1 of the low vacuum display part 36a is recessed when the inside of the container main body 10 is in a vacuum state. When the hemispherical portion 36a-1 is recessed, the hemispherical portion 36a-1 comes in contact with the central protrusion 22-2, and lifts the outline of the check valve 30. As a result, a gap is formed between the outside of the check valve 30 and the valve seating groove 22. Through such a gap, the outside air penetrates into the container body 10, causing food to spoil.

On the other hand, the hemispherical portion 36a-1 is thinner than other portions of the check valve 36 so that the inside of the container body 10 is easily recessed when it is in a vacuum state. Because of this, it can be easily torn off while being depressed. Through the torn portion, the outside air penetrates into the container body 10, and the food is damaged.

Fourth, since the air contact hole 24 is formed on the outer circumferential surface of the central projection portion 22-2, the central projection portion 22-1 is necessary. For this reason, it is difficult to make the lid body 20 into a simple shape.

Fifth, since the indentation protrusion 42-1 is inserted into the packing mounting groove 28-1 in the vertical upward direction, the lid body 20 is removed from the container body 10 in order to take out food stored in the container body 10. At the time of separation, due to the vacuum pressure applied to the interior of the container body 10, the indentation protrusion 42-1 is momentarily pulled out from the packing mounting groove 29-1 in a vertical downward direction, and the packing 40 is corrugated. Can be. Thereafter, when the user combines the lid body 20 to the body container body 10 that the packing 40 is not wrinkled, the contact portion 44 of the inlet 12 and the packing 40 of the container body 10 again. There may be a gap between). Through such a gap, the outside air penetrates into the container body 10, causing food to spoil.

An object of the present invention, the packing can be easily attached to the lid body without wrinkles, the outside air does not easily penetrate into the interior of the container body, due to the depression of the hemispherical portion, the outer edge of the check valve is lifted or the hemispherical portion is torn It is to provide a vacuum-sealing container that prevents the loss and prevents the lid body from being complicated by the central protrusion.

Vacuum sealed container for achieving the above object, the container body; It is coupled to the container body, a seating portion is formed in the center of the upper surface is formed, a check valve coupling hole is formed in the center of the seating portion, air contact holes penetrating the upper surface of the seating portion is formed around the check valve coupling hole is formed A container lid having a ring-shaped edge protrusion formed around the bottom surface thereof, and having a mounting groove formed along an outer surface of the edge protrusion; A ring portion inserted in the vertical direction to the edge protrusion, a mounting protrusion formed on an inner surface of the ring portion and elastically inserted into the mounting groove in the horizontal direction, and first wings and a second blade sequentially formed along the outer surface of the ring portion; A packing consisting of a wing and a third wing, made of an elastic silicone material; And a handle protrusion at an upper surface thereof, and a coupling protrusion inserted into the check valve coupling hole at a center of the lower surface thereof, and a check valve made of an elastic silicone material.

Using the present invention, the user can quickly and simply mount the packing on the lid body without wrinkles.

In addition, since the inlet circumference of the container body and the second wing of the packing are in surface contact, the contact area is widened, and even if the position where the container body and the lid body are slightly misaligned, the inlet circumference of the container body and the second wing There is no easy gap between the wings. Therefore, it is difficult for external air to penetrate inside the container body to spoil food.

In addition, if the rim is further provided along the circumferential surface of the container body, the second wing of the packing is in contact with the upper surface of the rim as well as the circumferential surface of the container body, the outside air becomes more difficult to penetrate into the container body.

In addition, not only the second wing, but also the first wing and the third wing that prevents the penetration of external air into the interior of the container body is further provided in the packing, it is difficult for the outside air to penetrate into the interior of the container body.

In addition, by eliminating the low vacuum display portion of the check valve, it is possible to prevent the outside lifting of the check valve and the tearing of the low vacuum display portion.

In addition, the center projection is removed, and the air contact hole is directly drilled on the upper surface of the seating portion to simplify the shape of the lid body.

In addition, due to the mounting projection inserted into the mounting groove in the horizontal direction, even when a vacuum pressure is applied to the inside of the container body, when the lid body is separated from the container body, the indentation protrusion does not fall out from the packing mounting groove in the vertical direction.

As shown in Figure 3 and 4, the container body 110 is a rectangular bowl that the area is wider toward the inlet 112 from the bottom surface 111. Of course, the container body 110, the area of the bottom surface 111 and the inlet 112 may be made of the same rectangular bowl. In addition, the container body 110 may be made of a circular bowl instead of a square bowl.

The container body 110 is made of plastic or glass.

The circumferential surface 112a forming the inlet 112 of the container body 110 is a flat surface rather than a curved surface. Thus, the second blade 134 of the packing 130 is in surface contact with the peripheral surface 112a of the inlet 112.

5 is a view showing a modification of the container body shown in FIG.

As shown in FIG. 5, the container body 110 ′ according to the modification further includes an edge 112 b ′ along the circumferential surface 112 a ′ of the inlet 112 ′. As a result, the second wings 134 (see FIG. 4) of the packing 130 (see FIG. 4) are brought into surface contact with the upper surface of the edge 112b ′ as well as the circumferential surface 112a ′ of the inlet 112 ′.

As shown in Figure 4, the container lid 120 is coupled to the inlet 112 of the container body (110).

The check valve coupling hole 121a is formed at the center of the seating part 121. The check valve engagement hole 121a penetrates the upper surface of the seating part 121.

Two air contact holes 121b are formed around the check valve coupling hole 121a. Of course, more air contact holes 121b may be formed. The air contact hole 121b penetrates the upper surface of the seating part 121.

When the check valve 140 is coupled to the seating part 121, the air contact hole 121b is covered by the check valve 140.

Border protrusions 122 are provided along the periphery of the lower surface of the container lid 120. The rim protrusion 122 is ring-shaped. The mounting groove 122a is formed along the outer surface of the edge protrusion 122. When the container lid 120 is coupled to the inlet 112 of the container body 110, the edge protrusion 122 is inserted into the interior of the container body (110).

The packing 130 is composed of a ring portion 131, a mounting protrusion 132, a first wing 133, a second wing 134, and a third wing 135. The packing 130 is made of an elastic silicone material. The mounting protrusion 132 is formed along the inner surface of the ring portion 131. The first wing 133, the second wing 134, and the third wing 135 are formed in order along the outer surface of the ring portion 131.
