Description

[Detailed Description of the Invention] The present invention relates to a pickle lid made of synthetic resin that can uniformly pickle the various pickle ingredients placed in a pickle container, has high rigidity, and can be provided at low cost.

When producing pickles, a weight such as a natural stone is usually placed on top of the pickle ingredients via a presser lid.

This press cover has been made from wooden boards for a long time, and in most cases, two semicircular boards are butted together and tied together with nails, etc. on the side on which the weight is placed (hereinafter referred to as the surface) via a connecting crosspiece to obtain materials. However, without exception, the side that came into contact with the pickle ingredients (hereinafter referred to as the "m side") was flattened.

Afterwards, a synthetic resin press cover appeared after solving the rust caused by the binding material of the wooden press cover and improving its durability, but it was natural to make the back side flat like the old wooden press cover. As shown in FIG. 8, the back surface 2 of the push lid 1 is flat, and in order to increase the overall rigidity, the shape has been followed to this day, with extremely gentle irregularities 3 on the surface.

However, the press lid with a flat back surface 2 has the following drawbacks.

First of all, the press lid is generally made much smaller than the opening of the pickle container, so if the top layer of pickle ingredients stored in the container is tilted for some reason, it will be easier to remove the lid if the back side is flat. This prevents the lid from slipping and leaning toward one wall of the container, which prevents the weight from being evenly distributed over all the pickle ingredients.

In addition, as pickles are pickled, they are dehydrated and water forms in the upper layer of the container, and in the case of pickled rice bran, the rice bran floats on the surface of the pickle ingredients, but if the back of the lid is flat, there will be several layers. The pickling material is pushed outward from the pressurized lid by the weight, that is, toward the wall of the container, making it difficult to evenly pickle the entire pickle material.

Furthermore, conventional synthetic resin press lids require a flat back surface, so they must be made thicker to provide rigidity, resulting in poor productivity and not being cheap enough to satisfy the price. The inventive presser lid was developed in order to eliminate the drawbacks of the conventional products as described above.

Next, an embodiment of the press lid of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a plan view showing an example of the lid of the present invention, and Fig. 2 is a cross-sectional view taken along the line ■--■.

A plurality of protrusions and concave grooves are provided concentrically on the disc-shaped press lid 4, and its cross section is shaped like a series of approximately sinusoidal waveforms 5, and the top of each protrusion 10 has a protrusion. 675S is provided, the back surface 7 of the protrusion 10 on the front surface 9 is made into a groove 8,
The back side of the groove on the front side is formed into a protrusion.

Note that reference numeral 11 indicates four holes drilled for ease of handling.

FIG. 3 shows another embodiment, and the lid 12 shown in this figure has a shape in which the projection 6 is removed from the lid 4.

Still another embodiment of the cover 13 shown in FIG.
6 is protruded from the center protrusion 15 to the outermost protrusion 16
As shown in FIG. 7, eight protrusions 17 having a substantially sinusoidal waveform in cross section are radially provided, and grooves 19 are formed on the back surface of the protrusions 17, as shown in FIG.

The pickle lid of the present invention has a plurality of ridges and grooves with a wave-shaped cross section on a disc having approximately the same wall thickness, and the grooves on the back or front surface correspond to the ridges on the front or back side. Since it is provided over almost the entire surface of the container, even if the top layer of the pickle ingredients stored in the container is tilted, the pusher lid will slip and end up on one wall of the container, placing weight on the entire pickle ingredients. Even if the bran is floating on the surface of the pickle raw material, the protrusions and grooves provided on the back side will properly block the bran, so the bran will not be absorbed evenly. The entire pickle raw material will not be ununiformly pickled by being pushed toward the wall side of the container, and the pickle raw material will not be damaged by the lid.

In addition, it has higher rigidity than the conventional synthetic resin press lid, which has a flat back surface and uneven surfaces only, and can be made thinner, resulting in high productivity and low cost products. Therefore, there is no rust caused by the binding material and it has excellent durability.
