Description

A lid of the container

The present invention relates to a lid structure of a container, and more particularly, to a lid structure of a container improved to maintain airtightness even when the lid is arbitrarily rotated in a state in which the skirt due to rupture of the annular thin plate is not separated.

As is well known, the plastic container containing the beverage is sealed by a lid with a safety device so that the consumer can know if it is opened.

1 shows a cross section of such a container. The container 10 has a male screw 12 formed on the outer circumferential surface of the inlet 11, and an annular jaw 13 is formed at the lowermost side of the male screw 12 along the circumference of the inlet 11.

Lid 20 is a handle portion formed with a circular base 29 in close contact with the upper end of the inlet 11 and a female screw 22 corresponding to the male screw 12 extending downward from the edge of the base 29. A lid body 21 made of 28 is provided, and a skirt 24 is connected to an end portion of the lid body 21 by an annular thin plate 23, and the annular body is formed on the inner circumferential surface of the skirt 24. The catching jaw 25 to be caught by the jaw 13 is formed.

Inside the lid 20 is provided with a sealing material 30 in close contact with the upper end of the inlet 11 of the container 10 to maintain airtightness.

When the lid 20 is rotated and opened, the lid body 21 is moved upward by being rotated by screwing, but the skirt 24 is caught by the annular jaw 13 by the locking jaw 25. Only by rotating it does not move upward with the lid body 21. At this time, as the annular thin plate 23 is broken, the lid body 21 is opened while being separated from the skirt 24.

Therefore, the consumer can determine whether the lid is open at the time of purchase by determining whether the skirt 24 is separated.

On the other hand, the sealing state of a lid may be unintentionally released. For example, when children leave the container to open the lid with weak force or when the container is transported or stored, the lid is slightly rotated due to friction or impact.

Preferably, the annular thin plate 23 is to be ruptured at the same time as the initial rotation of the lid body 21, but the lid body (such as a design error or deformation according to plastic container characteristics between the male screw 12 and the female screw 22). When the initial rotation of 21) as shown in Figure 2 can be generated without rupture of the annular thin plate 23.

In this case, the lid body 21 is rotated and raised as shown in FIG. 2 in a state where the annular thin plate 23 is not ruptured to release the airtightness inside the container. At this time, in the case of carbonated beverages, the contents leak due to carbon dioxide gas pressure, or the outside air is introduced, thereby causing the contents to deteriorate.

In addition, the support means; The sealing rib has an elastic support portion whose one end extends from the base to a diameter diameter, a sealing portion extending from the free end of the elastic support portion and tightly attached to an inner wall of the inlet of the container, and extending from the sealing portion to have a diameter reduced in diameter. With a guide,

The diameter of the sealing portion is larger than the inner diameter of the container inlet, characterized in that the diameter of the elastic support portion in contact with the base is formed to be smaller than the diameter of the sealing portion.

In addition, it is coupled between the inner circumferential surface of the handle portion and the outer circumferential surface of the sealing ribs is characterized in that the annular packing is further provided in close contact with the top of the inlet of the container to maintain the airtight.

The lid structure of the present invention prevents the leakage of contents because the sealing body is kept in close contact with the inner wall of the inlet of the container even if the lid body is undesirably rotated and the base of the lid body is spaced apart from the upper end of the container without breaking the annular thin plate. Make it possible.

In particular, since the adhesion between the sealing ribs is maintained by the support piece, it is possible to stably maintain the airtight state.

In addition, the diameter of the sealing portion of the sealing rib is formed larger than the inner diameter of the inlet of the container, the elastic support for elastically supporting the sealing portion is formed, and the guide portion reduced in diameter in the sealing rib is formed, thereby guiding the guide portion at the container inlet during assembly of the lid It is easily assembled and the sealing part is closely supported by the elastic support part. Accordingly, the lid body is undesirably partially rotated without breaking the annular thin plate so that even if the base of the lid body is spaced apart from the upper end of the container, the sealing body and the elastic support part maintain the close contact with the inner wall of the inlet of the container. To prevent it.

In addition, by having an annular packing coupled between the inner circumferential surface of the handle portion and the outer circumferential surface of the sealing rib, the top of the inlet of the container is in close contact with each other even if the lid body is undesirably rotated to maintain airtightness.

The container applied to the embodiment of the present invention is a synthetic resin container for storing beverages, such as beer or carbonated beverages, so that the container and the lid can be opened and closed by screwing.
