Abstract

An object of the present invention is to provide a structure of a synthetic resin container which does not come off when a lid is opened from a container body and can be superposed. Kind Code: A1 A lid made of a synthetic resin and capable of being covered by a container body, and a peripheral edge of one side of the container body and a peripheral edge of the lid opposed to the lid are connected by a belt-shaped hinge. When the lid is opened from the container body, the lid 9 can be turned 180 degrees while twisting the band-shaped hinge, and the inside of the lid has a length that can be overlapped with the outer bottom surface 5 of the container body.

Description

  The present invention relates to a structure for attaching and detaching the lid and body of a container with a synthetic resin lid. More specifically, even when the lid is opened from the container body, both of them are overlapped on the bottom of the container body via a belt-like hinge. The present invention relates to a synthetic resin container that can be combined.

  Conventionally, thin plastic containers with lids such as plastics such as polystyrene and polypropylene are constructed so that the lid and the container body can be separated separately as they are (Patent Document 1), and bendable between the lid and the container body. A hinge part is provided by integral molding and the lid can be freely opened and closed (Patent Documents 2 and 3).

  Among conventional synthetic resin lidded containers, the one of Patent Document 1 can be turned over as it is and overlapped with the main body, but on the other hand, there is a risk of being blown by an external force such as wind or being accidentally dropped. On the other hand, in Patent Document 2 and Patent Document 3, there is a restoring repulsive force in the hinge portion that connects the container body and the lid, and there is a disadvantage that the reopening force is reopened if there is no pressing means on the lid once opened. .

  Therefore, the present invention can be used by twisting the hinge part that connects the lid and the container body 180 degrees when the lid is opened from the container body and reversing the lid 180 degrees so that the inside is superimposed on the bottom of the container body. In addition, an object of the present invention is to provide a synthetic resin container that can be easily opened and closed without being blown by wind or external force by twisting the lid again after use and covering the original position of the container body.

  In order to achieve the above-mentioned object, the present invention is a belt made of a synthetic resin made of a synthetic resin and can be covered with a container body 1, and between the one side periphery 2 of the container body and the one side periphery 3 facing the cover. When the lid is opened from the container body 1, the band hinge can be turned 180 degrees while twisting the band hinge, and the inside of the lid overlaps the outer bottom surface 5 of the container body 1. The ribs 11 and 12 are in contact with each other when they are superposed on the outer bottom surface 5 of the container body 1 and the inner top surface 4 of the lid 9. Thus, the space 13 is formed between the container body and the lid.

  According to the present invention, since the synthetic resin container body and the periphery of the lid are connected by a belt-like hinge having an appropriate length, the lid can be opened via the belt-like hinge even when the lid is opened from the container body. Since it is connected to and integrated with the lid, the lid does not detach from the container body due to an external force such as wind, and there is no risk of falling accidentally.

  Furthermore, even when hot food is stored directly in the container body, since it is thermally insulated by the space formed between the outer bottom of the container body and the inner top surface of the lid, It is difficult to transfer heat directly. Therefore, even a child can easily hold it with bare hands. Thus, it is convenient and highly convenient especially when used outdoors in the wind or when storing hot foods. In addition, since the container body and the lid are integrated by overlapping, the strength of the container body as a whole is increased, and the thickness of both can be reduced and the cost can be reduced accordingly. Furthermore, when the lid is opened, there are many advantages such as no need for a place for the lid and ease of use.

  The present invention is not limited to household food containers, but can be used in a wide range as small-sized containers for every use or food containers.

It is an external view of the container main body and lid | cover of this invention. It is an external view when a cover is opened. It is an external view when a lid is inverted 180 degrees. It is an aspect figure when a lid | cover is piled up on the container main body lower side. It is an external view when covering a container main body with a lid | cover. It is sectional drawing when a lid | cover is piled up on the lower side of a container main body.

  Details of the present invention will be described below with reference to FIGS. The flange portions of the container body 1 and the one side periphery 2, 3 of the lid 9 are integrally connected to each other by a belt-like hinge 6, and each can be freely reversed via the belt-like hinge.

  Each of the container main body, the lid, and the belt-like hinge is formed of a so-called synthetic resin such as polystyrene resin, polyethylene terephthalate resin, or polypropylene resin. Among these, the belt-like hinge 6 has a thickness of the container body 1 or the lid 9 ( The inner top surface 4 of the lid is made to be the outer bottom surface 5 of the container body 1 by twisting 180 degrees on both sides. Is set to a length that can be superimposed.

  Further, the bottom surface of the container body 1 has a concavo-convex rib 11 serving also as a reinforcement, and the inner top surface 4 of the lid 9 faces the rib 11 when the inside of the lid 9 is superimposed on the container body. Protruding ribs 12 are formed at positions so that a space 13 is formed between the outer bottom 5 of the container body 1 and the inner top surface 4 of the lid 9 when they are overlapped (see FIG. 6).

  Further, the flanges of the peripheral edges 2 and 3 of the container main body 1 and the lid 9 are fitted with the container 9 covered by the lid 9 from above. On the other hand, the belt-like hinge 6 is a thin plate having a width of approximately 1 to 3 centimeters. However, when the belt-like hinge 6 is twisted 180 degrees together with the lid 9, the width dimension or thickness thereof does not cause deformation deformation. If a bellows-like crease is partially formed according to the dimensions, it can be expanded and contracted and the appearance is good.

  The belt-like hinge 6 may be formed integrally by connecting means such as welding or bonding after the container body and the lid are separately formed, or may be a stretchable plate-like or string-like member. Needless to say, it is good.

  Next, the operation of the present invention described above will be described. First, when the food is stored in the container body 1, the lid 9 is opened as shown in FIG. 2, and then the lid is twisted so as to be reversed 180 degrees between the strip hinges 6 (FIG. 3). The top surface 4 is overlaid on the outer bottom surface 5 of the container body (FIG. 4) to store or pack the food (not shown).

  Thereafter, the lid 9 is reversed so as to return 180 degrees again, and the lid 9 is put on the container body 1 while twisting the belt-shaped hinge 6 back (FIG. 5). At this time, the belt-like hinge 6 has a length that allows the container main body 1 and the lid 9 to be overlapped with each other and is thinned so that twisting of 180 degrees is possible, or by forming a crease as described above, The appearance is good without any irregularities.

  In this embodiment of the present invention, the shape of the container body 1 has been described as a boat-shaped container. However, the present invention is not limited to this, and the same applies to a shape that can be overlapped with a lid, such as a round shape, a box shape, or a polygon shape. It has the action and effect of. In addition, it is needless to say that the container main body 1, the lid 9, and the belt-like hinge 6 do not have to be made of the same material, and can be appropriately selected according to the purpose and size of use.
