Description

[Detailed Description of the Invention] The present invention relates to a sealed container with a lid made of synthetic resin that has a strong lid, excellent permanent sealing performance, and is decomposable.

Among containers made of synthetic resin, food containers such as bento boxes need to have excellent sealing properties, as they may contain contents that release liquid or the like. Usually, such a container is sealed by bringing a gasket provided on the lid side into close contact with the upper end surface of the container body, that is, the opening edge surface. However, in containers with lids made of synthetic resin, the lids may become deformed due to changes over time, and in such cases, the sealing performance naturally deteriorates.

Furthermore, food containers are required to be kept clean because they are used for food. However, in conventional containers with lids, as a means of pressurizing and sealing the lid equipped with a seal and the container body, a hook is rotatably pivoted to the lid or container body, and a receiver is attached to the container body or lid. Since the hanger has a structure that can be hung on the hook, dirt easily accumulates in the pivot point of the hanger and is difficult to clean. In order to clean the hinge part of the hanger, all you have to do is remove the hanger, but
Conventional containers with lids do not anticipate such a situation, so the hanger is difficult to remove, and if the container is attached and removed frequently, the hanger and the pivot joint may be damaged.

This invention was devised in view of the above-mentioned drawbacks of conventional sealed containers with lids made of synthetic resin.The purpose of this invention is to provide a lid with high strength and permanent sealing properties. To provide a sealed container with a lid which is excellent in terms of performance and in which all accessories can be disassembled for cleaning etc.

A sealed container with a lid according to the present invention for achieving the above object has a structure including a container body, a lid that covers the opening of the container body, and a lid that is provided along the entire periphery of the edge of the lid and that covers the opening of the container body. In a sealed container with a lid that includes a sealing material that contacts an edge surface and seals between the container body and the lid, a receiving portion is provided protruding from at least two opposing outer surfaces of the container body, and A reinforcing wire is fitted on the outside, and a portion of the wire is bent at a portion along the side surface of the lid corresponding to the side surface of the container body where the receiving portion is provided, to form a pivot portion, and a pivot portion is formed on the tip side. The proximal end portion of a latching tool having a hook portion that can be latched to the receiving portion is rotatably fitted to the pivot portion.

EMBODIMENT OF THE INVENTION Hereinafter, the sealed container with a lid according to the present invention will be described in detail based on an embodiment shown in the drawings. Among the drawings, Fig. 1 shows a partially cutaway plan view of the lid of one embodiment, Fig. 2 shows its front view, Fig. 3 shows a side view with half of the lid cut away, and Fig. 4 shows a side view with half of the lid cut away. 2 shows an enlarged cross section of a part of the joint between the lid and the container body.

Reference numeral 1 denotes a container body made of synthetic resin of the sealed container with a lid, and its planar shape may be any shape such as a rectangle or an oval, but here it is a rectangle with rounded corners. A receiving portion 2 having a substantially trapezoidal planar shape is protruded from the upper middle of both long sides of the container body 1, and a locking protrusion 3 is provided at the tip of the lower surface of the receiving portion 2. The receiving portion 2 has enough rigidity to not easily deform, and is molded integrally with the container body 1 during manufacture. 4 is a synthetic resin lid of the sealed container with a lid;
The container body 1 has a plate shape with a planar shape substantially similar to that of the container body 1. A packing storage groove 6 is provided in a portion of the lid 4 that faces the opening edge surface (upper end surface) 5 of the container body 1, and a packing 7 is accommodated therein as a sealing material. This gasket 7 is removable. A flange 8 protrudes from the lower part of the lid 4 along the entire circumference, and wire fitting grooves 9 are formed along the longitudinal direction above the flange 8 on both sides in the longitudinal direction. . It has an annular shape that is almost the same as the planar shape of the lid 4, and the width direction is the lid 4.
The reinforcing wire 10 is slightly smaller than the width of
However, its longitudinal portion is fitted into the wire fitting groove 9 and then fitted into the lid 4. The reinforcing wire 10 consists of a longitudinal portion 10a and a short portion 10b facing each other, and a curved portion 10c connecting these portions, and is made of highly rigid metal or synthetic resin. By fitting the reinforcing wire 10 with high rigidity, the strength of the lid 4 is significantly improved, and deformation such as warping over time does not occur. Note that the reinforcing wire 10 and the lid 4 are perfectly fitted together because the reinforcing wire 10 is fitted into the wire fitting groove 9. One or more locking protrusions 11 may be provided to prevent the short side portion 10b from coming off. Longitudinal portion 10a of reinforcing wire 10
Pivot portions 10d are formed by bending and deforming the wire outward at two locations. These pivot parts 10d
The latch 12 is pivotally attached to the holder. The latching tool 12 is integrally molded from synthetic resin and consists of left and right arms 13 and a hanging part 14 that connects them.The base end of the arm 13 is a pivoting part, and a pivoting groove 15 extends from the back side to the center part. A retaining protrusion 16, 17 is provided near the opening. In addition, hanging part 1
The lower part of number 4 protrudes toward the front to make it easier for your fingers to hang onto it. This latch 12 is pivotally attached to the reinforcing wire 10 by fitting the pivot groove 15 at the base end of the arm 13 into the pivot section 10d, and is rotatable about the pivot section 10d. . Since there are retaining protrusions 16 and 17 near the opening of the pivot groove 15, the latch 12 will not come off from the reinforcing wire 10 unless force is applied from the outside. The lid 4 and the container body 1 are coupled by rotating the hook 12 and hooking the hook portion 14 onto the receiving portion 2 of the container body 1. When the lid 4 and the container body 1 are connected, the gasket 7 on the lid side is pressed against the opening edge surface 5 of the container body 1, thereby sealing the container. In addition, receiving part 2
A locking protrusion 3 is provided on the tip edge of the locking protrusion 3, and since a counterforce acts between the locking tool 12 and the receiving part 2 due to the elastic force of the gasket 7, the locking tool will not hold unless force is applied from outside. The engagement between the hanging part 14 of 12 and the receiving part 2 never comes off.

When washing the sealed container with a lid, remove the latch 12 from the reinforcing wire 10, remove the reinforcing wire 10 from the lid 4, and remove the packing 7 from the packing storage groove 6 of the lid 4. Disassemble all items. All of the above parts are fitted, so they can be easily removed. Since it is disassembled and cleaned, you can clean every detail.

In the above embodiment, the groove 9 provided on the side surface of the lid 4 is used as a means for fitting and holding the reinforcing wire 10 into the lid 4, but no groove is provided on the side surface of the lid 4. A plurality of locking protrusions 11 similar to the locking protrusions 11 provided on the short side portion of the lid 4 are provided on opposing sides or at least one on each side, and these locking protrusions and the flange of the hem of the lid 4 are provided. 8 may be used to hold the reinforcing wire 10. Further, in the above embodiment, the latching mechanism consisting of the latching tool 12 and the receiving part 2 is provided only on two sides of the container, but if the container is large, it may be provided on all the sides. Furthermore, in this embodiment, the lid 4 forms part of the latch mechanism.
Although the receiver 2, which serves as a handle for holding the container body 1 when opened, has a trapezoidal planar shape, it may of course have other shapes.

As described above in detail based on one embodiment, according to the sealed container with a lid according to the present invention, reinforcing wire is fitted into the lid to improve its strength, so deformation of the lid is prevented and the lid and the container body are bonded together. The sealing properties can be maintained permanently. In addition, all accessories such as reinforcing wires and latches can be disassembled, so when cleaning the container, it can be disassembled and cleaned thoroughly, allowing the container to be kept clean at all times.
