Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to perforated cover assemblies used as container lids, particularly but not exclusively as lids on cooking utensils such as pots, frying pans, roasting pans, and the like. While the use of such a lid prevents liquid bottles and faceplates from splashing out of the container, the force is free to escape from the container.

The present invention can be used primarily with cooking utensils, where the perforated cover assembly is used to prevent grease and/or water from escaping from simmering cooking utensils, while preventing surface wood and liquids from escaping from containers. It can also be extended to the case of ponds where it is desirable to prevent them from escaping.

An example of such an application is acid dilution.

Cooking, and 1) In dishes that involve deep-frying or grilling,
It is important that water vapor can escape from cooking utensils, and many people prefer to do so if grease or other liquids are not splashed from the cooking utensils.

BACKGROUND OF THE INVENTION Numerous culinary products have been proposed to date with the aim of achieving these desired results. The main body of such a device consists of a fine mesh sieve placed in a peripheral support frame with a handle. It is believed that the sieve prevents liquid from escaping while allowing gases such as water vapor to escape. However, in reality, the above is often only partial and ineffective.

In another available form of cover, two substantially flat sheets are spaced apart and sealed to each other around the outer periphery of the sheets, each sheet having a number of through holes offset from one another between the sheets. have The cover is intended to be used over pots and pans of various sizes. When placed on a small pound or pot, condensation forms on the outer area of the cover and drips onto the stove surrounding the pot or pot. Moreover, the inner surface of the thin plate cannot be cleaned sufficiently in many cases.

Additionally, in most cases, at least, it is easy to add liquids such as water to the kava while keeping it in a working position on top of the pot or pan. do not have. Many other structures are also expensive or labor intensive to manufacture, and the structures do not lend themselves to simple mass production techniques.

OBJECTS OF THE INVENTION It is an object of the present invention to provide an improved perforated cover assembly that obviates at least some of the disadvantages of prior art covers.

<Achievements and Effects of the Invention> According to the present invention, a perforated cover assembly as described below is provided. A cover assembly consisting of two perforated shell members removably joined at their peripheries to define a space in their openings, one shell member as a topmost shell member and the other shell member as a bottommost shell member. used. The upper or lower shell member has at least one through hole, and the lower or lower shell member is recessed to form an effective central minimum area, the minimum area having at least one drainage hole. It has a through hole for drainage, that is, a drainage hole. The lower shell member has a number of outlet through holes or perforations distributed over at least a major portion of the surface excluding the drainage holes. Each of the through holes communicates with the interior of the cover assembly at a portion that is higher than the inner surface of the lower shell member around the through hole. The through holes in both shell members are arranged in relation to each other to prevent liquids and solids from passing straight through the cover assembly.

Furthermore, the present invention has the following features. The through hole in the lower shell member is formed by the inner end of a short tubular portion formed in the shell member, the axis of which is perpendicular to the plane of the shell abutment, and which is conveniently generally truncated conical. - The central lowest region has a short tubular portion facing in the opposite direction forming the drainage hole. Both shell members have outer peripheries that are removably connected to each other and have an outer shape that is concave on opposite sides. The upper shell member includes a chimney by which liquid can be directed through the cover assembly and into the container via a drainage hole in the central lowest region.

Most preferably, the chimney is formed to align with an inwardly recessed, unperforated portion through the center of the upper shell member and toward the interior of the opposite center of the lower shell member. A circumferential circular area surrounding the inwardly directed recess forms a central lowest area with respect to the recess and has a series of through holes.

The holes are preferably sized to be comparable to many conventional cover assemblies, with a hole diameter of 2 tnh.
It is more preferable that the length is from + to 10 mrn, and most preferably from 3 mm to 8 mrn. One preferred pore size is approximately 5111I+1. This large pore size provides substantially unrestricted escape of gas or vapor from the cooking utensil on which the cover assembly rests.

The upper shell member need not have multiple holes, but rather has a single central hole that is large enough to accommodate all force flow through the cover assembly.

The single hole is defined by the chimney stem given the shape of the chimney.

On the other hand, if desired, especially in the absence of a chimney, a number of staggered holes can be provided in the upper shell.

Condensed liquid and other liquids that adhere to the inner surface of the upper shell member are
In order to prevent it from flowing into the outer joint with the lower shell member,
Near the outer periphery of the lower shell member, a ridge is preferably provided which extends downwardly into the lower shell member. In this way,
Condensate or liquid flows down the ridges and into the lower shell member. Alternatively, the upper shell member may be recessed in the same direction as the lower shell member to a medium extent than the lower shell member.

The shell members may be made from any suitable material, but in particular by pressing aluminum or stainless steel sheets and punching through holes therein. However, it is within the scope of the present invention to mold the shells from a suitable heat resistant plastic material or an alternative heat resistant glass material such as that sold under the trade name "Pyrex". Glass is more preferred when chemicals are involved in the cover assembly.

The outer circumferential shape of the cover assembly is made to be complementary to the outer circumferential shape of a container such as a cooking utensil used together with the cover assembly.

The cover assembly may therefore be circular, oval, oval or rectangular as desired.

Generally, circular shapes are preferred. This is made clearer by the fact that one cover assembly can be used for a wide range of pots and pans of different sizes without condensation dripping onto the outside of the pot or pan.

The shell parts may be hinged to each other at - points and removably joined at - points or at several different angular positions, but more preferably to facilitate cleaning and handling. They can be completely removable from each other. Various mechanical arrangements can be used for this purpose, some of which are discussed below.

In this embodiment of the invention, two very shallow recessed shell members 1 and 2 are removably connected by an annular flat part 3 and 4 on the outer periphery. Both shell shrines are circular and the annular planes 3 and 4 are connected by a headed pin, for example a flat-headed pin 5, which is fastened to the annular flat part 4 of the lower shell part 2. The flat head pin extends into the annular portion of the upper shell member 1 through a hookhole slot 6.

The wide part 7 of the hook-shaped groove is clearly intended to allow the head 8 of the flathead pin 5 to pass through, and the adjacent groove 9 is held in place by this head. A common pin 105, slightly taller than the other pins, and a common slot 106 on the outer periphery cooperate to help align the flat head pin with the hookhole groove. This pin cooperates with the removable rotating fastener 1( ) 7 to prevent the upper and lower shell members from inadvertently rotating one rotation relative to each other and separating.

In this embodiment of the invention, the shell member is made by pressing stainless steel sheets, and the free ends of the outer circumference are bent outward and inward, as indicated by the numeral 10, in order to provide rigidity to the outer annular surface 3.4. ing. This also prevents the danger caused by exposed sharp edges of the sheets.

The lower shell member has an inwardly recessed area 11 in the center, and a number of through holes 12 are scattered on the remaining surface.

The outlet of each through hole is the inner surface and one end of the tubular truncated cone, and the through hole extends inward to the space 1 between the upper and lower shell members.
It has reached 3.

The inward depression area 11 and the concave shape of the lower shell reach a circular valley 14 surrounding the depression area, and this central valley is the lowest part compared to the others. The drainage hole 15 is
They are arranged in a circular pattern in this valley, and are formed in the same manner as the above-mentioned through holes, except that the tubular truncated cone is directed downwardly from the space 13 between both shell members to the outside. This generally allows moisture, including condensation, to drain into a pot or pan located below the center of the lower shell member. On the other hand, an inwardly directed tubular truncated cone formed as a through hole is sometimes placed over a pot or pan.
This is to prevent moisture from spilling out of the through hole 12 when the shell member is placed so that the through hole 12 is located outside the outer periphery. The depressions in the lower shell direct such moisture into the valleys and drainage holes 15.

In this embodiment of the invention, the lower shell member has one large central hole 16 in the form of a funnel-shaped chimney 17 and leading into the space 13 between the two shell members.

As shown more clearly in Figure 3, the two shell members 1 and 2
The chimney is of a sufficiently shallow concave profile to facilitate installation by bending the inner end of the funnel-shaped chimney over the shell, as indicated by the numeral 18. In such a case,
As shown by arrow 19 in Figure 3, whether solid or liquid,
It is impossible for the water to pass through the drain hole 15 of the lower shell member and escape to the outside of the chimney without colliding with the side wall of the funnel-shaped chimney.

The chimney also serves as an outside handle when the cover assembly is raised.

A downwardly directed groove is provided to allow oil or liquid that passes through the through-hole in the lower shell member and impinges on the inner surface of the upper shell member to drain properly out of the lower shell member and finally out of the drainage hole 15 surrounding the recess 11. A shaped structure 20 is provided near the outer periphery of the upper shell. This groove-like structure reaches all the way to the bottom of the lower shell, as indicated by the numeral 21. In this way, the liquid flowing down the inner surface of the upper shell part falls down the groove-like structure 20 and flows through the annular parts 3 and 4.
cannot flow up to the contact surface.

In use, the cover assembly can rest on a pot or pan of any diameter less than its maximum diameter and greater than the diameter of the drainage hole array circle.

When the cover assembly is placed on the cooking utensil in this way, liquids and solids cannot escape out of the lid. In any case, the liquid is conducted via the chimney 17 and the drain hole into the interior of the cooking utensil on which the lid rests.

Drainage holes also return condensed liquid back into the cooking utensil. This indigo can be used in both water and pond cooking liquid. Water vapor and pond steam and gases nevertheless freely pass through the through holes. Cleaning of the cover assembly is simply accomplished by rotating the two shell members apart from each other so that the head of the flathead pin fits into the wide portion of the keyhole groove, and washing them.

It will be appreciated that various modifications may be made to the above-described embodiments of the invention without exceeding the scope of the invention.

In particular, the method of joining the two shell members can vary widely.

In a more preferred variant shown in FIGS. 6 and 7, the U-shaped lips 22 on the arms 23 supported via the axis of rotation are spaced around the outer circumference of the shell. The arm rests on the upper shell by a rivet 24 which acts as a rotational axis and has a radius approximately so that the clip can be moved away from the shell ends (as shown in FIG. 6) or to push the bent ends 10 of both shell members together. can be moved to interlock in the direction (as shown in FIG. 7). The free end of the arm of the U-shaped lip is bent outward! &25 serves as a fingerhold to remove the necessary sharpener loop.

Furthermore, examples of changes are shown in FIGS. 8 and 9. In this case, the diametrically opposite image portion 26 of one shell member is bent (
For example, it is folded at the edges, forming two straight and parallel groove-like structures. The corresponding straight end of the other shell member is inserted into the groove by sliding both shell members diametrically relative to each other. On the outer periphery of the shell member with the seams, between the two seams, the raised part 27 is continuous on the one hand, and the flat part 28 is continuous on the other hand.

2. The upper shell member is inserted into the lower shell member until its tip 29 contacts the raised portion 27.

In this position, both shell members maintain a cooperative relationship.

In this variation, there is a chimney with a tubular stem 30 extending into the space 31 between the shell members. The chimney made it possible to use a lid with a more pronounced concave profile that would prevent liquids and solids from splashing out of the large central hole in the upper shell member.

A series of holes 32, similar to, but offset from, the through holes in the lower shell are also shown through the upper shell. The arrangement of holes is such that liquids or solids cannot pass straight through the cover assembly.

It is believed that the present invention provides a significantly simpler but effective perforated cover assembly made of a variety of materials as needed.

The cover assembly can be properly cleaned and is therefore completely hygienic. Additionally, gas flows substantially unrestricted through the cover assembly of the present invention. The above-mentioned cover assembly is recognized for its true value from the above-mentioned points, and
Used to prevent chemicals from splashing on people's clothing, especially in chemical laboratories.
