Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a container lid,
In particular, it relates to a lid that is always stable in an inverted state when removed from a container.

[0002]

2. Description of the Related Art The lid of a container filled with daily use foodstuffs such as a liquid or granular seasoning is easily removed and sized so as to be easily grasped by hand so as not to be lost. .

The shape of the lid is generally cylindrical and has a body for gripping during removal and resealing, and a circular top having substantially the same area as the cross section of the body. . The material is easy to handle and manufacture,
Materials such as thermoplastic plastics are often used.

[0004] When a seasoning or the like filled in a container is used, the lid is removed from the container, and the removed lid is usually turned upside down from the viewpoint of hygiene and placed on a table or the like.

[0005]

Although such a lid is constructed so that it can be easily removed from the container and resealed, the stability of the lid after being removed from the container is not taken into account. It has not been.

The removed lid is light in weight and lacks stability. If the lid is not properly placed upside down or accidentally placed on a table and placed on the side, the side of the body of the lid comes into contact with the table surface. Rolls and lids may bounce on the table and fall off the table. In this case, the filling of the container adhering to the portion for sealing the container inside the lid scatters on the table or the floor, and bacteria on the table or the floor adhere to the entire periphery of the lid, which is unsanitary.

If the lid is placed on the table without being inverted, the filling of the container adhering to the portion for sealing the inner container falls onto the table, and the surface of the table becomes dirty. There is also a hygienic problem because it adheres to the entire periphery of the mouth.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a stable and easy-to-handle hygienic container lid which is always in an inverted state when removed from the container. I do.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a container lid having a body and a top, the top being flat and having an area smaller than the cross section of the body. This is achieved by a lid characterized in that the center of gravity is near the top so that when the lid is removed from the container it is always upside down and stable.

In the lid of the present invention, when the body is cylindrical and the top is circular, the lid is more likely to be in an inverted state depending on the angle of the portion connecting the body and the top.

In the lid according to the present invention, when the trunk is a hollow polygonal column and the top is polygonal, the lid is more likely to be in an inverted state depending on the angle of the portion connecting the trunk and the top. .

When the lid of the present invention is integrally formed of a thermoplastic material, the production is easy and the cost can be reduced.

When the lid of the present invention is configured so that the thickness near the top is thicker than other portions, the center of gravity can be set near the top with a simple configuration.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a container lid according to an embodiment of the present invention. In the drawings, the same components are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 1 is a perspective view showing an embodiment of a container lid according to the present invention. The lid 1 of the present invention has a cylindrical body 10
A top 11 which is flat, has a circular shape, and has an area smaller than the cross section of the body, and a curved surface 12 which connects the body 10 and the top 11 with a predetermined curvature. or,
Inside the lid, an engagement portion 13 having a female screw corresponding to a male screw provided at the mouth of the container is provided to rotate and screw the lid to the container to seal the container. I have. The entire lid is integrally formed of a thermoplastic material such as plastic, and the thickness near the top 11 is thicker than other portions.

An engaging portion 13 provided inside and a top portion 11
Since the vicinity is thicker than other parts, the center of gravity of the lid 1 is near the top 11.

FIG. 2A shows a state in which the lid of the container shown in FIG.
FIG. 4 is a diagram showing a state where the side of the device has been placed on the table surface 20 by tilting it to the side so that the side surface thereof contacts the table surface 20.

When the lid 1 is placed on the table surface 20 in a state as shown in FIG. 2A, the center of gravity of the lid is near the top, so that the lid 1 is inverted in the direction indicated by arrow A in the figure by gravity. The force for setting the state acts, and the curvature of the curved surface 12 also contributes to the movement of turning the lid upside down so that the top 11 comes into contact with the table surface 20 and becomes stable as shown in FIG. .

Therefore, the side wall of the body of the lid does not roll in contact with the table surface or the lid bounces on the table and does not fall off the table, and the filling of the container adhered to the portion inside the lid that seals the container. Can be prevented from scattering on the table or the floor. In addition, even if the lid is turned to the side and placed on the table, it will be immediately inverted and stable without rolling, so the germs present on the table will only adhere to a small part of the side of the lid And does not adhere to the entire periphery of the lid.

When the lid is inadvertently dislodged after being in an inverted state, the lid rises and becomes in an inverted state again like a small priest, and is stabilized.

Hereinafter, a modified example of the present embodiment will be described.

FIG. 3 is a view showing a modification of the lid of the container shown in FIG. The lid 1 of this modification has a different cross-sectional shape from the lid shown in FIG.
Is a polygon corresponding to the body, and the curved surface 12 is composed of a plurality of curved surfaces having a predetermined curvature.

As in the above-described embodiment, a female screw corresponding to a male screw provided at the mouth of the container is provided inside the lid so that the lid is rotated and screwed into the container to seal the lid. Is provided in the engaging portion 13. The entire lid is integrally formed of a thermoplastic material such as plastic, and the thickness near the top 11 is thicker than other portions.

An engaging portion 13 provided inside and a top portion 11
Since the vicinity is thicker than other parts, the center of gravity of the lid 1 is near the top 11.

When the lid of the present modification is placed on the table surface with the side surface of the body being in contact with the table surface, the lid is similar to that described with reference to FIG. It is automatically inverted and stable.

In the above-described embodiment of the container lid of the present invention, the shape of the body is a cylinder or a hollow polygonal column, and the shape of the top is a circle or polygon corresponding to the shape of the body. However, the shape is not limited to this, as long as it is a shape that automatically becomes an inverted state when the center of gravity is near the top.

In addition, the portion inside the lid for sealing the container is screwed into the container by rotating the lid with respect to the container. However, the lid may be slightly smaller than the outer diameter of the mouth of the container. A small inner diameter may be used to engage with the mouth, but the lid of the container of the present invention is not particularly limited as to the method of sealing the container.

[0028]

According to the lid of the automatic inverted type of the present invention, the center of gravity is near the top even when the side of the body is turned sideways so as to be in contact with the table surface and placed on the table. As a result, a force that causes the lid to be inverted by gravity acts, and the lid is in an inverted state with the top part down and is stabilized.

Therefore, when the lid is removed from the container and placed on a table or the like, the lid is in an inverted state without any special attention from the user, so that it is easy to handle. The container filling adhered to the part that seals the container inside the lid does not fall down from the table because it rolls on the table or the lid bounces on the table. Can be prevented from adhering to the entire periphery of the lid, which is sanitary.

In addition, even if the lid is inadvertently dislodged after being once in an inverted state, the lid rises and becomes an inverted state again like a small practitioner, and is stabilized.

When the body is cylindrical and the top is circular, the lid is more likely to be turned upside down depending on the angle of the portion connecting the body and the top.

When the body has a hollow polygonal column shape and the top is polygonal, the lid is more likely to be in an inverted state depending on the angle of the portion connecting the body and the top.

When integrally formed of a thermoplastic material, the production is easy and the cost can be reduced.

In the case where the thickness near the top is thicker than the other portions, the center of gravity can be set near the top with a simple configuration.
