Description

  The present invention relates to a container for storing food, and more particularly to a container that is used during storage, refrigeration, freezing, and cooking, and more particularly, a container that is suitable for cooking in a microwave oven by a parchment paper technique.

  The method of cooking food with parchment paper is to wrap food to be cooked with parchment paper, and put the wrapped food (wrapping) in an oven at a temperature and time suitable for cooking the food. Is done. This cooking method is performed in combination with steam released from the wrapped food. When cooking is complete, the wrapping is removed from the oven, the wrapping is opened or broken, the food is removed, and the paper is then discarded. Although this cooking method is performed in a conventional convection oven, cooking with parchment paper has recently become more common. The reason for this is that a microwave oven has appeared and usability has improved due to the use of the microwave oven. The paper used is not necessarily any paper, it is a special paper that does not allow fluids and vapors to pass. Particularly suitable for wrapping food, it is a paper that can withstand temperatures of 200 ° C. or higher and is sold at special stores. The disadvantage of this special disposable paper is high cost and is not always present in ordinary households. When such special paper does not exist, it is common to use aluminum foil instead. But this also has drawbacks. First, aluminum foil is easy to tear, for example, corners and bones of food to be cooked break the wrapping, and juice and food may spill. Furthermore, aluminum foil is not suitable for use in a microwave oven because it is made of metal.

  Containers with removable lids made of plastic or elastomeric materials are commercially available. This container is used to cook food using parchment paper technology. Some of these containers are made of platinum-catalyzed silicon and can be used in both conventional convection ovens and microwave ovens. However, conventional containers do not always meet the special conditions of cooking in a convection oven or microwave oven. For example, conventional containers have a flat bottom that contacts the support surface of the microwave oven. The support surface prevents hot air or electromagnetic waves in the oven from contacting the outer surface of the bottom of the container. For this reason, the cooking time of a food becomes long, and also causes uneven cooking. Furthermore, since silicon is elastic, the walls of this type of container must be made quite thick to provide sufficient stiffness to handle the container. Moreover, since the heat transfer characteristic of silicon is poor, the cooking time becomes longer due to the thick wall.

  The present invention solves the above drawbacks. A container suitable for cooking in a microwave oven or an oven according to the present invention includes a container made of an elastomer material into which food is put through an access opening, and a cover material covering the opening. The container is formed from one or more walls. The wall has a curved bottom wall and an opening edge that defines an opening at a position higher than the bottom wall. Furthermore, a plurality of reinforcing ribs are formed to protrude outwardly from at least one outer surface of the bottom wall and surround all or most of the outer surface of the bottom wall when the container is disposed on the support surface. A plurality of support portions to be exposed to each other are provided.

With such a structure, the bottom wall and other walls of the container can be made extremely thin by the rigid action of the reinforcing ribs. For example, when platinum catalyst silicon is used as the elastomeric material, these walls are 0.5 to 0.9 mm thick. This is considerably thinner than conventional containers without reinforced ribs. When the wall of the container becomes thin, the heat conduction function is improved and the time required for cooking can be shortened. Furthermore, the support structure provided by the reinforcing ribs allows the curved bottom wall to be separated from the support surface (of the microwave oven), allowing the entire container to be exposed to hot air or electromagnetic waves in the oven. As a result, the food in the container can be cooked evenly at high speed.
According to an embodiment of the present invention, the bottom wall has an elongated channel shape that defines a side edge of the opening, and is connected to an end wall that defines an end surface edge of the opening at its end. Yes. An end face edge of the opening of the container is curved in a convex shape, and has a lower level of the side edge of the opening and a central region raised to the upper side of the side edge of the opening. The cover means has only one curved lid or two curved lids. The lid has a side edge adjacent to a side edge of the opening of the container and a concavely curved end face edge that rests on the end edge of the opening of the container in the closed position. Thus, the container and the lid or the plurality of lids constitute an elongated hollow container having an elliptical cross section in the closed position. Although not absolutely necessary, it is desirable that the lid or lids are likewise made of an elastomeric material and are integral with the container. The reinforcing ribs of the container are spaced apart from and parallel to the end wall. Similarly, a plurality of reinforcing ribs arranged in parallel to and spaced from the end wall so that the thickness of the plurality of lids between the lids or the ribs can be extremely thin. Have For example, when platinum catalyst silicon is used as the elastomeric material, these lids are 0.5 mm to 0.9 mm thick.

  The kitchenware (container) of the present invention that contains food suitable for cooking in a microwave oven has a container 10. The container 10 is made of an elastomeric material suitable for containing food and has an access opening (hereinafter simply referred to as “opening”). The kitchen utensil further has cover means for closing the opening. This cover means has one lid 20 (FIGS. 1 and 2) or two lids 30 and 40 (FIGS. 3-11). The lid is separable from or integral with the container 10. The container 10 is formed from a plurality of walls having a curved bottom wall 1. The wall of the container 10 provides open edges 5, 6, 8, and 9. The opening edges 5, 6, 8 and 9 form an opening at a position higher than the bottom wall 1. A plurality of reinforcing ribs 7 provide a plurality of support protrusions. The plurality of support protrusions protrude outward from the outer surface of the bottom wall 1, and when the container 10 is disposed on the support surface (of a microwave oven, oven), all or the outer surface of the bottom wall 1 Most are exposed to the surrounding atmosphere.

  A first embodiment of the present invention will be described with reference to FIGS. The bottom wall 1 of the container 10 has an elongated channel shape that defines the open edges 5, 6 on the sides. The bottom wall 1 is connected to the end walls 2 and 3 at its ends. End walls 2 and 3 define end face opening edges 8 and 9. The opening edges 5 and 6 on the side surfaces are formed by the bottom wall 1 of the container 10 and are substantially straight and horizontal. In other words, it is parallel to the mother surface of the bottom wall 1. The end face opening edges 8 and 9 are formed by the end walls 2 and 3 of the container 10 and are curved in a convex shape. This convex shape forms a lower stage at the level of the side opening edges 5 and 6 and has a central region that becomes the apex above the side opening edges 5 and 6. The end walls 2 and 3 have an elliptical shape with the major axis in the horizontal direction when viewed from the side. The bottom wall 1 is connected to the lower half of this elliptical shape. As an option, the end walls 2, 3 may be slightly inclined in a direction to open upward from the bottom wall 1. The connection between the side opening edges 5 and 6 and the end opening edges 8 and 9 is made at the rounded transition. A plurality of reinforcing ribs 7 are arranged on the bottom wall 1 of the container 10 so as to be spaced apart from each other in parallel to the end walls 2 and 3. As a result, the reinforcing ribs 7 extend from the central longitudinal region 4 of the bottom wall 1 to the corresponding side opening edges 5, 6. The lower portion of the reinforcing rib 7 is configured to provide the support member described above. The reinforcing rib 7 protrudes outward from the outer surface of the bottom wall 1. As a result, the inner surface of the bottom wall 1 is smooth and preferably has a glossy polishing finish to facilitate cleaning.

  In this first embodiment, the cover means has a curved lid 20. The lid 20 is made of the same elastomer material as the bottom wall 1 and forms an integral part with the container 10. For this purpose, the lid 20 has a first side edge 21 and a second side edge 22. The first side edge 21 is connected to one of the opening edges 5 of the bottom wall 1 of the container 10 by a hinge means 23. The second side edge 22 is arranged on the opening edge 6 of the bottom wall 1 of the container 10 in the closed position (the lid is closed). Further, the lid 20 has end edges 24 and 25 which are concavely curved on the inside. These end edges 24, 25 rest on the open edges 8, 9 of the container 10 in the closed position. The radius of the concave curves of the end edges 24 and 25 of the lid 20 is smaller than the radius of the convex curves of the opening edges 8 and 9 of the container 10. The reason for this is to match the maximum deformation that the lid 20 receives when configuring the container 10. Thus, in the closed position shown in FIG. 2, the container 10 and the lid 20 constitute an elongated hollow container having a substantially elliptical cross section. The lower half of the hollow container is formed by the container 10 and the upper half is formed by the lid 20.

  The lid 20 has a peripheral rim 26 on the inside. The peripheral rim 26 extends inwardly from the inner surface of the lid 20 and extends along at least most of the outer periphery of the lid 20. The peripheral rim 26 reinforces the rigidity of the lid 20 and is arranged between the side opening edge and the end opening edge 5, 6, 8, 9 of the container 10 in the closed position. The lid 20 has a plurality of reinforcing ribs 27 on the outside. The ribs 27 are parallel to the end walls 2 and 3 of the container 10 and protrude outward from the outer surface of the lid 20. Thus, the inner surface of the lid 20 is smooth and preferably has a glossy polished finish to facilitate cleaning. As another configuration, the rib 27 may protrude inward from the inner surface of the lid 20, but this is limited to the case where the rib formed on the inner side does not come into contact with the food stored in the container 10.

  The end walls 2 and 3 of the container 10 have handles 11 and 12, respectively. The handles 11 and 12 extend laterally outward in a cantilever manner from the convexly curved opening edges 8 and 9 to form a convexly curved upper surface common to the opening edges 8 and 9. The end portions 28 and 29 cover the handles 11 and 12 when the lid is closed. End portions 28 and 29 extend laterally outward from end edges 24 and 25 of lid 20 in a cantilevered fashion. The end portions 28 and 29 of the lid 20 are fitted with the handles 11 and 12 of the container 10 in the upper portion. Handles 11 and 12 each have an embossing (not visible in FIGS. 1 and 2) formed on the lower surface of each, thereby increasing the heat transfer surface and preventing the user from being burned with the handle, Provide a non-slip surface to facilitate gripping. As shown in FIG. 2, the embossing 53 is also formed on the outer surfaces of the end portions 28, 29 of the lid 20 for the same purpose.

  The main difference between the second embodiment of FIGS. 3-11 and the first embodiment of FIGS. 1 and 2 is that the second embodiment has two lids 30 and 40, and the first embodiment has one sheet. This is a point having a lid 20.

  The container 10 of the second embodiment is similar to that of the first embodiment, but has a curved bottom wall 1. This bottom wall 1 is in the form of an elongated channel, has a central longitudinal region 4 in the lower part and an upper edge parallel to the base surface of the bottom wall 1. This upper edge forms the opening edges 5, 6 on the sides of the opening to the container 10. The bottom wall 1 is connected to the end walls 2 and 3 at its ends. The end walls 2, 3 define the end face opening edges 8, 9 of the opening to the container 10. The opening edges 8 and 9 are curved in a convex shape, have a lower end at the level of the opening edges 5 and 6, and have a central region that protrudes above the opening edges 5 and 6. In the illustrated second embodiment, the end walls 2 and 3 have an elliptical shape. Its long axis is in a horizontal position, and the bottom wall 1 is connected to the lower half of this elliptical shape. The connection between the side opening edges 5 and 6 and the end face opening edges 8 and 9 is made at a rounded transition. A plurality of reinforcing ribs 7 protrude outward from the outer surface of the bottom wall 1 of the container 10. The plurality of reinforcing ribs 7 are arranged in parallel to the end walls 2 and 3 and spaced apart from each other.

  As shown in FIGS. 5 and 9, the reinforcing ribs 7 constitute two groups of ribs. These ribs are aligned from one side of the central longitudinal region 4 of the bottom wall 1 to the other and extend from the central longitudinal region 4 to the corresponding side opening edges 5, 6. The lower portion of the reinforcing rib 7 provides a support member 63 (FIGS. 10 and 11). This support member 63 keeps the container 10 stable on the support surface and exposes the entire outer surface of the bottom wall to the surrounding atmosphere (except for the line in the central longitudinal region 4). As another structure, the reinforcing rib 7 is continuously arranged from one side of the bottom wall 1 to the other side so that the entire outer surface (including the central longitudinal region 4) of the bottom wall is exposed to the ambient atmosphere. Also good. Since the reinforcing ribs 7 protrude outward from the outer surface of the bottom wall 1, the inner wall of the bottom wall 1 preferably has a glossy polishing finish so that it is smooth and easy to clean.

  The lids 30 and 40 are curved and have first side edges 31 and 41, second side edges 32 and 42, and end edges 34, 35; 44, 45 curved in a concave shape, respectively. The first side edges 31, 41 of the lids 30, 40, which are made of an elastomeric material and form an integral part with the container 10, are axially hinged to both the open edges 5, 6 of the bottom wall 1 of the container 10. 33 and 43 are connected. As a result, the lids 30 and 40 rotate around the hinge means 33 and 43 between a position where the lid is opened (FIG. 3) and a position where the lid is closed (FIG. 4). In the closed position, the second side edges 32, 42 of the lids 30, 40 are adjacent to each other on the central longitudinal region 4 of the bottom wall 1 of the container 10. The concavely curved end edges 34, 35; 44, 45 of the lids 30, 40 rest on the convexly curved end surface opening edges 8, 9 of the container 10.

  The lids 30 and 40 have peripheral rims 36 and 46 on the inner side. The peripheral rims 36, 46 extend inwardly from the inner surface of the lids 30, 40 and extend along at least most of the outer periphery of the lids 30, 40. The peripheral rims 36, 46 reinforce the rigidity of the lids 30, 40 and are arranged between the side opening edges and the end opening edges 5, 6, 8, 9 of the container 10 in the closed position. As shown in FIG. 10, the longitudinal portions of the peripheral rims 36, 46 are adjacent to each other above the central longitudinal region 4 of the bottom wall 1 in the closed position. The lids 30 and 40 further form a plurality of spaced apart reinforcing ribs 37 and 47. The ribs 37 and 47 are parallel to the end walls 2 and 3 of the container 10. The ribs 37 and 47 extend outward from the outer surfaces of the lids 30 and 40. As a result, the inner surfaces of the lids 30, 40 have a glossy polished finish that is smooth and easy to clean.

  The end walls 2 and 3 of the container 10 have handles 11 and 12, respectively. The handles 11 and 12 extend laterally outward in a cantilever manner from the convexly curved opening edges 8 and 9 to form a convexly curved upper surface common to the opening edges 8 and 9. The lids 30, 40 have end portions 38, 39; 48, 49, respectively. These are adjacent to the concavely curved end edges 34, 35; 44, 45 and extend laterally outward in a cantilevered manner. This fits into the handles 11, 12 in the closed position and has a concavely curved surface on the lower side to cover (FIG. 9). As shown in FIGS. 8 and 9, the end walls 2 and 3 are slightly inclined so as to open in the outward direction of the bottom wall 1. Similarly, the handles 11 and 12 are also inclined slightly upward and outward from the end walls 2 and 3 of the container 10. When the lids 30, 40 are in the closed position, the end portions 38, 39; 48, 49 of the lids 30, 40 are deformed to match the inclination of the handles 11, 12.

  One lid, specifically the lid 30, has a flap 54 in the longitudinal direction. This flap 54 extends from its second side edge 32 over its entire length. The flap 54 is sized to cover the other lid, specifically the area adjacent to the second side edge 42 of the lid 40 when the lids 30, 40 are closed. Emboss 52 is formed on the outer surface of flap 54. The emboss 52 has a “ridge” shape in the longitudinal direction that increases the rigidity of the second side edge 32 of the lid 30. Each end flange 55, 56 extends laterally outward from the end of the flap 54 in a cantilevered manner. When the lids 30 and 40 are closed, the end flanges 55 and 56 of the lid 30 protrude from the end portions 48 and 49 of the other lids 40 (FIG. 9). Grip and lift the lid 40 before lifting it. Further, the end portions 48 and 49 of the lid 40 have the second side edge 42 which overlaps in the closed position, and the protrusions 57 and 58. The protrusions 57, 58 extend laterally outward in a cantilever fashion and extend from the handles 11, 12 of the container 10 under the end flanges 55, 56 in the closed position (FIG. 9). The protrusions 57 and 58 are shorter than the end flanges 55 and 56. As a result, the end flanges 55 and 56 are first grasped and the lid 30 is opened. As a result, when the lid 30 is opened, it can be gripped separately to open the lid 40.

  The embosses 51 and 53 increase the heat conduction surface and prevent the user from being burned. This is because it is easy to grip the container with the lids 30 and 40 closed. The embosses 51 and 53 are formed on the lower surfaces of the handles 11 and 12 and the upper surfaces of the end portions 38 and 39 of the lid 30 having the flaps 54. Similarly, end flanges 55 and 56 have a lower surface on which embossing 64 is formed. This makes it easier to increase and grip the heat transfer surface. The embossing 53 of the end portions 38, 39 of the lid 30 extends to the upper surface of the end flanges 55, 56.

  As shown in FIGS. 10 and 11, the lids 30 and 40 and the container 10 form an elongated hollow body having an elliptical cross section when the lid is closed. As described above, the end face opening edges 8 and 9 of the end walls 2 and 3 of the container 10 are convexly curved, and the end edges 34 and 35; 44 and 45 of the lids 30 and 40 are concavely curved. On top. The radius of the curved curves of the end edges 34, 35; 44, 45 of the lids 30, 40 is smaller than the radius of the curved curves of the convex end edges 8, 9 of the container 10. Thus, the end portions 38, 39; 48, 49 of the lids 30, 40 are slightly deformed and adapted to the curves of the handles 11, 12, thereby providing a tight closed state. This is advantageous in view of the fact that the lid is tight with its own weight and does not require any other special closure means.

  In both the first and second embodiments of the present invention, each of the hinge means 23 or the hinge means 33, 43 has a thin band 59. Ridges 60 and 61 are formed on both sides of the band 59. The ridges 60, 61 are adjacent to the side opening edges 5, 6 on the corresponding side of the container 10 and the first side edges 21, 31, 41 of the lids 20, 30, 40. FIG. 6 is an enlarged view of one part of the hinge region 43. At each end of the hinge means 23 or at each end of the hinge means 33, 43, a tear-preventing cord 62 is connected in a loop shape, preferably an arc shape, so as to connect the container 10 and the lid 20, 30, 40. It is formed so that it protrudes in a portable form. This tear prevention cord 62 is separated from the end of the thin band 59 of the hinge means 23, 33, 43 by a loop protruding in a cantilever manner, and does not prevent the thin band 59 from bending. However, since the tear prevention cord 62 is thicker than the band 59, it prevents the band 59 from tearing and breaking. FIG. 6A shows another embodiment of this hinge means. In the figure, the tear prevention cord 62 extends parallel to the end edge of the thin band 59 without forming a portion in the form of an arc or loop protruding in a cantilever manner. The ends of the band 59 and the ridges 60 and 61 are connected to the tear prevention cord 62. Alternatively, the band 59 and / or the ridges 60, 61 may not be connected to the tear prevention cord 62.

The elastomeric material of the first and second embodiments of the present invention is preferably platinum catalyst silicon. This platinum material silicon can withstand both high and low temperatures and is suitable for kitchen use. As a result, the kitchen utensils (containers) of the present invention are suitable for storing food during storage, refrigeration, freezing, and cooking. In particular, the food is cooked in a microwave oven, for example, using the technique of parchment paper It is suitable for cooking. Furthermore, as a result of providing the reinforcing ribs 7, 27, 37, 47, the wall thickness of the container 10 and the wall thickness of the lid 20, the walls of the lids 30, 40 between the reinforcing ribs 7, 27, 37, 47 are provided. The thickness of the thin film is 0.5 mm-0.9 mm. This is preferred for heat conduction or electromagnetic waves through the bottom wall 1 and the lid 20 or lids 30, 40 during cooking.

  As shown in the first and second embodiments, the lids 20, 30, and 40 are connected to the container 10 by hinge means 23, 33, and 43. It can also be separable from 10. As a result, in the closed position, the first side edges 31, 41 of the lids 30, 40 are simply adjacent to the side opening edges 5, 6 of the container 10, or the ribs 37, 47 are the inner surfaces of the lids 30, 40. Or may protrude from both the inner and outer surfaces of the lids 30,40.

  Those skilled in the art can consider various modifications of the present invention based on the above-described embodiments of the present invention, all of which are described in the claims of the present application. Included in the technical scope.
