Description

The present invention relates to a ceramic container used for storing food.

Ceramic containers are manufactured by firing clay containing feldspar, quartz, etc., which are raw materials, in a state of being molded into a product shape. When firing, the shape of the product shrinks, so the shape and thickness of each part of the product vary slightly. This variation is caused by, for example, when the shape of the rim, which is the end of the opening, is formed in a substantially square frame shape, and a part of the rim is bent more than the surroundings, in other words, a corner having a large curvature is formed. Once formed, the variation due to shrinkage tends to increase in and around the corner. Therefore, it is necessary to devise the shape of the rim portion so that the above variation does not hinder the covering of the container with the lid.

By the way, as a food storage container used for storing food in a refrigerator or the like, in order to use the storage space as efficiently as possible, the dead space is relatively smaller than that of a container having a circular outer shape. A container shape with an outer shape is preferred.

For example, Patent Document 1 discloses a substantially box-shaped ceramic container configured so that the lid and the container body can be sealed without a gap by providing a fixing layer made of beeswax in advance on the lid of the ceramic container. ing.

Utility Model Registration No. 3219700

In the container described in Patent Document 1, the container body and the lid can be brought into close contact with each other by using beeswax, but the opening end of the container body has a substantially square frame shape and a corner portion is formed, so that a firing step is performed. There is a problem that the shape of the product tends to collapse and it is difficult to manufacture.

An object of the present invention is to provide a ceramic container that can efficiently utilize a storage space such as a refrigerator while facilitating the manufacture of the container.

The ceramic container of the present invention is composed of an accommodating portion configured to have a substantially quadrangular shape in a top view, and a substantially annular rim portion provided above the accommodating portion.

In the ceramic container of the present invention, a lid having an insertion portion which is configured to be insertable into the mouth edge portion and has a groove at a position facing the mouth edge portion, and an annular shape fitted into the groove portion. A sealing material may be provided, and when the lid is put on the rim portion, the sealing material may be configured to close the gap between the rim portion and the insertion portion.

According to the food storage container of the present invention, the accommodating portion is configured so as to form a substantially square outer shape when viewed from above, and the rim portion provided on the upper part of the container body is configured in a substantially annular shape. This makes it possible to prevent the product shape from collapsing after the firing step. As a result, the storage space such as a refrigerator can be efficiently used while facilitating the production of the container.

Hereinafter, the ceramic container 10 according to the embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1A and 1B, the ceramic container 10 includes a container body 20 for storing food and a lid 30 for covering the container body 20. The container body 20 and the lid 30 are each made of earthenware. Further, the container body 20 is composed of an accommodating portion 22 and a rim portion 24 provided on the upper portion of the accommodating portion 22. As shown in FIGS. 2 (a) and 2 (b), the accommodating portion 22 has a substantially quadrangular shape that is point-symmetric in top view, and more specifically, the four corner portions 22a, 22b, 22c, and 22d are rounded, respectively. It is formed in a so-called rounded square shape. Further, the accommodating portion 22 is configured such that a substantially central portion in the vertical direction when the rim portion 24 is removed bulges in an arc shape in a side view. On the other hand, the rim portion 24 is formed so as to form a substantially annular shape, in other words, a round cylinder shape. Further, as shown in FIG. 2A, the housing portion 22 having a substantially quadrangular shape is formed to be larger than the mouth edge portion 24 in the top view. With these configurations, it is possible to increase the capacity in the accommodating portion 22 while preventing the mouth edge portion 24 from losing its shape during firing.

Here, FIG. 3A is a side view showing the configuration of the lid 30 attached to the container body 20. FIG. 3B is a side view showing a state in which the sealing material 40 is attached to the lid 30. FIG. 3C is a plan view showing the structure of the sealing material 40. As shown in FIGS. 3A and 3B, the lid 30 is formed so that the upper portion 32 is formed in a flange shape and the appearance shape is substantially circular in the top view. Further, the center of the upper portion 32 of the lid 30 is formed so as to be slightly recessed from the peripheral portion. A truncated cone portion (insertion portion) 34 is provided on the back side of the lid 30. The truncated cone portion 34 is formed to be slightly smaller than the inner diameter of the rim portion 24 so that it can be inserted into the rim portion 24 when the lid 30 is attached to the container body 20 (FIG. 1 (b)). reference). A circumferential groove 34a formed in an annular shape is provided on the side surface of the truncated cone portion 34. As shown in FIG. 1B, a sealing material 40 (see FIG. 3C) having an annular flexibility made of a resin material such as polyethylene or silicon is fitted into the peripheral groove 34a. There is. As a result, the gap between the rim portion 24 and the lid 30 can be closed with the lid 30 attached (covered) to the container body 20.

In this way, the accommodating portion 22 can be maintained in a sealed state simply by covering the container body 20 with the lid 30. Further, since the sealing material 40 has flexibility, the lid 30 can be easily removed from the accommodating portion 22. Further, as shown in FIG. 3C, a small through hole 42 may be provided in the sealing material 40. By providing the through hole 42, the lid 30 can be removed from the container body 20 more smoothly.

Further, for example, in a storage container with a lid made of resin, both the container body and the lid are flexible. Therefore, when the lid is removed from the container body, the container body and the lid are easily elastically deformed, which may take time and effort to remove the lid. On the other hand, in the ceramic container 10 of the present embodiment, when the lid 30 is removed, neither the container body 20 nor the lid 30 is flexible, so that the container 30 is not deformed, and the lid 30 can be removed. There is also the advantage that it does not take time and effort.

According to the ceramic container 10 in the present embodiment, the accommodating portion 22 is configured so as to form a substantially quadrangular outer shape when viewed from above, and the rim portion 24 provided on the upper portion of the accommodating portion 22 is configured in a tubular shape. To. As a result, the shape of the rim portion 24 can be prevented from collapsing after the firing step. Further, since the accommodating portion 22 can be configured to have a substantially square shape when viewed from above, there is little dead space when the accommodating portion 22 is stored in a storage space such as a refrigerator, and the storage space can be efficiently used.

The present invention can also be carried out in a mode in which various improvements, modifications, or modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Further, within the range in which the same action or effect is produced, any of the invention-specific matters may be replaced with another technique.

4 (a) to 6 (b) are drawings showing the design of the ceramic container 10. As shown in FIGS. 4A to 5B, the ceramic container 10 is configured to have the same design form shown in the front view, the rear view, the right side view, and the left side view. To.
