The present invention generally relates to a lid of a container, and more particularly to a lid of a method of sealing a container by pressing with a finger.

Until now, lids for sealing containers have the necessary strength, elasticity, including compressed fibers, paper, cellulose raw materials, plastic materials and their condensates or various combinations thereof. And flexible materials.

The present invention is a lid which can be attached to the opening of the container by hand or mechanical means to make it click or not, and can be peeled off from the container by peeling off operation. It relates to a lid for sealing the container in the shape of a recessed stopper.

In particular, the present invention relates to a lid of a plastic container that can be reused for a container with an open mouth, and provides a lid device and a sealing method in which a quick and easy use and a continuously reliable seal are made. Another feature of the present invention is to provide a hermetic lid, which is produced by compression or injection and is economically manufactured and has the characteristics as described above.

The new lid also has some striking structural features that make it more suitable for use in containers and other tubular objects related thereto. Among these features are the conical, dish-like or convex center walls that facilitate the contraction of the periphery of the wall so that the wall portion of the lid easily enters the container and expands to seal the wall of the container.

Hereinafter, the present invention with the above characteristics will be described in more detail with reference to the accompanying drawings. In the drawings, like parts are designated by like reference numerals.

In the accompanying drawings, the number 10 denotes a conventional container represented by a conical side wall abutting the peripheral rim 11. A similar container is indicated by the number 12, which differs in that the annular projection 13 is provided on the rim of the inner wall of the inner wall of the container.

The vessels 10 and 12 can be in any shape and can be of a flexible, semi-rigid or rigid material such as plastic, glass or metal. When using rigid materials, sealing is done by applying a relative pressure between the wall of the container and the wall of the lid.In the case of using flexible or false materials, the lid described below can provide a bioresistance that provides a sealing effect. Have

The lid, generally indicated by the number 14, has a central wall 16 of conical, hyperbolic or uneven surface and also includes a U-shaped annular groove inverted upward from its periphery. The outer wall 18 is in contact with the top of the inner wall 20 while forming a groove, and the top wall, that is, the connecting wall 22 is joined to these side walls.

It should be noted that the inverted U-shaped groove formed by the walls 18, 20 and 22 has a width such that when the lid is used for the opening of the container, the wall 18 does not catch the rim 11. do. Of course, the wall 18 may be removed, or its shape may be modified to prevent the wall 18 from being caught by the rim 11 when the central wall 16 is inserted into the opening. Similarly, in the embodiment of FIG. 3, the annular protrusion 24 is provided in the sealed wall of the wall 20. As shown in FIG. This annular projection 24 has an effect of sealing the inner circumferential wall of the container 12 under the annular projection 13 by snapping the annular projection 13 in the container 12 when the lid is fitted into the container. Therefore, the annular projection 13 serves as a stop mechanism to partially restrain the lid so that the lid 14 does not move upward.

To insert any lid into the container, place the inverted groove of the lid over the mouth or top of the container rim and press the center of the center wall 16 with a thumb or other mechanical means to close the side wall 20 of the groove. Let it contract As such, the lid is configured to contract and expand so as to be partially crushed, so that the wall 20 is configured to contract and expand so as to be displaced with the central wall 16. This role is due to the elasticity and elasticity of the constituent materials used, especially due to the shape of the center wall, which is carefully constructed using their inherent physical properties.

These shapes can be conical, hyperbolic or concave and convex, extending out at the center point or actually at the flat portion 26 as shown in FIGS. 5, 8 and 10 degrees. Since the center wall 16 is essentially curved, when the pressure is applied to almost its center point, the center wall itself tends to crush. When the central wall 16 is crushed in this way, the wall 20 is displaced completely evenly inward. Theoretically, if the central wall is not rigid or is not reinforced by the walls 18, 20 and 22, the whole of the central wall will continue to crush into an umbrella-like shape.

As pointed out above, the embodiment of the lid shown in FIG. 3 also includes an outwardly protruding annular protrusion 24 circumscribed around the wall 20. 3 also shows an undercut or inverted shelf 28, where the annular protrusion 24 touches the inner wall of the container 12 under the undercut 28 to form a seal.

The relative distance between the inner surface of the wall 22 in the U-shaped frame and the annular ledge 24 and between the staging and undercut 28 of (11) is that the entire annular ledge is undercut when the container and lid are closed. It is placed underneath and is not in contact with it. Thus, the actual seal is made between the outer side of the annular ledge 24 or the wall 20 (FIG. 4) and the side wall of the container and is not in contact with the undercut 28.

Significantly different sizes between the inner surface of the wall 22 and the annular protrusions 24, and between the top edge of the rim 11 and the undercut 28, do not require precise tolerances for them. Because. For example, in order to maintain a continuous seal between the annular ledge and the undercut, it would be necessary to ensure that virtual line contact is maintained between these portions because of their respective contours. However, in the apparatus thus described, it is only necessary to keep the annular protrusion 24 under the undercut 28 so that the sealing is made on the virtual flat wall surface.

Therefore, the undercut 28 serves to sound audible when the lid slides into contact with the container to achieve proper closure and also serves to restrain the lid in the opening of the container as indicated above. In this regard, it should be noted whether the undercut 28 can continuously achieve the desired effect and whether the position of the undercut and the annular ridge in the container and cover is reversed depending on the desire.

In addition, as apparent in the embodiment of FIG. 4, the undercut 28 need not be used. For example, when the action of the lid of the present invention is not impaired, it is not necessary to undercut the rim 11 of the representative tubular object or the container 10 and the annular protrusion 24 can be removed.

To lift one lid out of the container, the wall 18 is held between the thumb and the other finger and easily and conveniently peeled off the rim 11 of the container in a manner that does not click silently.

Lids and containers made of glass or similar material as the lid material may be used for the packaging of alcoholic beverages, carbonated beverages, fruits, pickles, milk and its products, cheeses, candy, other foodstuffs and beverages, It is used for pharmaceuticals, proprietary preparations, and the like.

The lids described above are formed by compression injection, or other casting techniques. The quality of the lid construction is improved by the properties of the lid material. These properties do not absorb and are not easily soaked in water, withstand odors against acids, alkalis, solvents and other chemicals at normal temperatures, and do not soften well below the boiling point of water. It contains a thermoplastic compound such as rubber, which is resistant to mold, resistant to microorganisms and insects, has flexibility and elasticity that slowly recovers, and when it comes into contact, generates friction and softens. The material of these lids includes polymers of ethylene known under the trade names “polytyne” and “polyethylene”.

Although the present invention has been described in detail with reference to particularly suitable embodiments thereof, it is possible to make various changes and modifications within the spirit and scope of the present invention as described in the text and set forth in the appended claims.
