 The present invention relates to a closed container with a plastic lid used for packing and selling processed foods such as seafood and edible wild plants.

[0002]

[Prior art]

 A conventional closed container with a lid has a hard body and a soft lid, and a ridge is formed on the outer peripheral surface of the upper end of the peripheral wall of the body. It is often used that a reversely bent edge piece is formed on the inner surface of the edge piece, and a groove is formed on the inner peripheral surface of the edge piece so that the groove fits into a protrusion of the body. Even in this case, when the ribs of the body are triangular in shape with a downward clearance angle in the cross section, the lid sealing state is stable, but it does not come off as it is. It can be cut along.

In the cutting device, as shown in FIG. 1 of the embodiment, a cutout window 29 is provided in a part of the edge piece 17, a lower end portion of the cutout window 29 projects from one end, and a point connection is made to the other end. The knob 31 is formed, and the lower end portion 17a of the edge piece 17 is torn off by breaking the point connection portion 33 by grasping the knob 31.

[0004]

[Problems to be solved by the device]

 According to the conventional closed container with a lid as described above, the tight connection between the rib of the body and the groove of the lid prevents the leakage of juice, and the lid never comes off until it is opened. Although it is safe, it has a structure in which the annular ridge and the annular groove are joined together in one line, so conditions such as when the inside thermally expands or is shocked during transportation. Depending on the case, the juice could leak.

In particular, after opening the container, even if the lid was closed, there was no connection between the annular projection and the annular groove, so that the juice was likely to leak.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a closed container with a lid capable of reliably preventing leakage of juice.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the first invention is composed of a body made of hard plastic and a lid made of soft plastic, and the lid is vertically inverted and bent so that the lid is attached to the upper end of the peripheral wall of the body. A channel-shaped edge piece is formed, and at the upper end of the peripheral wall of the body, annular ridges are provided in upper and lower two steps on the outer peripheral surface, and it is formed downward in a triangular cross section, and the edge of the lid is formed. On one side, upper and lower two-stage annular groove fitting both annular protrusions was formed, and a cutting device along the upper annular groove was provided for opening to form a closed container with a lid.

A second invention comprises a body made of hard plastic and a lid made of soft plastic, and an inverted channel-shaped edge portion which is vertically inverted and refracted so that the lid is attached to the upper end of the peripheral wall of the body. A piece is formed, and at the upper end of the peripheral wall of the body, an annular step portion is formed on the inner peripheral surface of which the lid is hooked, and the lid has an annular fin that elastically presses against the edge of the annular step portion. Then, a closed container with a lid was constructed.

The third invention is constructed by adding the structure to the second invention as in the second invention.

According to a fourth invention, in the first and third inventions, the body and the lid are formed in a rectangular shape, and are formed in a curved shape which is close to a circle over the entire circumference.

[0011]

[Action]

 The upper and lower two-tiered annular protrusions provided on the upper edge of the peripheral wall of the body each have a triangular shape with a downward clearance angle. Therefore, it is possible to cover the edge piece with the edge piece on the upper edge of the peripheral wall. Since the annular projection and the annular groove are joined to each other in the upper and lower two stages by the attachment, the sealed state on the outer surface of the peripheral wall is ensured. Further, on the inner surface, since the annular fin of the lid elastically presses against the edge of the annular step of the body, a reliable sealed state can be obtained here as well.

Further, when the body and the lid are formed in a rectangular shape, they have an advantage that they do not take up a lot of space when they are arranged, but since they are curved over the entire circumference, the end of the edge piece of the lid is It can be cut smoothly along the upper annular groove.

When opening, the lid cannot be opened as it is due to the sectional shape of the annular projection, and the cutting device cuts the edge piece along the position of the upper annular groove, so that the upper and lower annular grooves are cut. Release the connection with the ridge.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

The closed container with a lid is composed of an injection-molded hard plastic body 1 and a soft plastic lid 3 which is also injection-molded, and is sealed on both inner and outer surfaces of a peripheral wall 5 of the body 1. Then, a cutting device 4 for releasing the inner sealed state is provided. Although it is a circular container as a whole, it can be carried out in the same manner even if it is a rectangular shape such as a square.

On the outer surface of the peripheral wall 5 of the body 1, a stepped portion 7 is provided near the upper end portion in a protruding shape, and two annular raised ridges 9 and 11 are provided above the stepped portion 7, each having a clearance angle downward. Although formed in a triangular shape, the lower annular protrusion 11 is formed small. By doing so, the lid 3 can be easily attached as will be described later.

On the inner surface of the peripheral wall 5, there is provided an annular step portion 13 having a vertical surface on the lower side above the step portion 7 having a protruding shape on the outer surface, and above that is curved in a circular arc shape in section. An annular recess 15 is formed.

The lid 3 is formed with an inverted channel-shaped edge piece 17 which is vertically inverted and refracted from a position where the periphery is hooked on the annular step portion 13. The edge piece 17 has a channel-shaped inner surface. In addition, annular grooved ridges 19 and 21 that hang with the annular ridges 9 and 11 of the body 1 are formed. Of these, since the lower annular groove 21 is a shallow groove, when the lid 3 is attached, the lid 3 easily passes through the upper annular groove 19 of the body 1 and is not caught by it. Can be done easily. Further, when the edge piece 17 is cut off by the cutting device 4, it is cut off at a predetermined upper annular groove position 19.

The lid 3 is further provided with an annular fin 23 projecting elastically at the edge of the annular step portion 13 of the body 1. Further, an annular convex portion 25 that fits into the annular concave portion 15 is formed above the annular fin 23. This fitting also prevents leakage of juice and stabilizes the connection between the body 1 and the lid 3 after the lower end 17a of the edge piece 17 is cut off.

Although the peripheral wall 5 of the body 1 and the edge piece 17 of the lid 3 are in an airtight state in which no space is formed between them, the annular protrusions 9 and 11 and the annular grooves 19 and 21 are connected to each other. In order to improve the close contact with the above, a slight space 26a, 26b is provided between the peripheral wall 5 and the edge piece 17 below the upper annular protrusion 9. Further, in the annular step portion 13, a space 27 is provided between the annular fin 23 and the body 1 so that the annular fin 23 can be pressed against the edge of the annular step portion 13 in the entire circumference by line contact.

When the body 1 is covered with the lid 3 and the edge piece 17 is pushed into the upper end of the peripheral wall 5, the annular protrusions 9 and 11 and the annular groove portions 19 and 21 are connected in two steps, so that both are connected. The lid 3 cannot be opened without releasing. Therefore, the cutting device 4 has a structure in which the edge piece 17 is cut along the upper annular groove 19.

In order to secure this cutting position, the cutting device 4 is provided with a notch window 29 having an upper edge at a height position P corresponding to the depth of the groove of the upper annular groove 19, and the notch window A knob 31 is formed at the lower end of 29 to project from one end and connect to the other end at a point. Then, by pulling the knob 31 to cut off one end at the point connection portion 33 and tearing off the edge piece 17, the lower end portion 17a of the edge piece 17 is completely removed at the position of the upper annular groove 19. It is torn apart along the circumference.

When the edge piece 17 is cut at the end 17a in this manner, the connection with the upper and lower two-stage annular projections 9 and 11 is released, so that the lid 3 can be opened. However, when the lid 3 is covered, a tight contact with the peripheral wall 5 is obtained, so that the leakage of juice can be prevented. In particular, since the annular fin 23 is in pressure contact, it can be said that its preventive action is great.

FIG. 3 and FIG. 4 show another embodiment, in which the closed container with a lid forms the body 1 and the lid 3 in a regular quadrangle, and is close to a circle over the entire circumference. It is formed in a curved shape. That is, with respect to the lid 3, each side 3a of the prism is formed into a curve close to a large circular arc, and the corner 3b is formed into a small circular arc. When formed in this way, the rectangular shape has the advantage that it does not take up much space when arranged like a box, even if it has the same capacity as the circular shape.

In addition, unlike the case where each side is a straight prism having a straight shape, in the cutting device 4, since the upper annular groove 19 is curved over the entire circumference, the end 17a of the edge piece 17 is formed. Can be cut smoothly along the upper annular groove 19. In the case of a true prism, useless force is required to cut off the end 17a of the edge piece 17, and there is a disadvantage that the corner is easily broken.

When the end 17a of the edge piece 17 of the lid 3 is cut off, the knob 31 is operated so as to be pulled out through the cutout window 29, but a bulged portion 31a in a cross section is formed at the tip thereof so as to facilitate the picking. Further, the lower annular protrusion 11 is formed in an isosceles mountain-shaped cross section. Further, the lid 3 is provided with a turning piece 30 on the notch window 29 so that the lid 3 can be easily opened. The turning piece 30 also serves to prevent the inconvenience that the knob 31 is inadvertently cut in the cutout window 29 when the knob 31 comes into contact with another object during transportation.

As the hard plastic of the body 1, polystyrene (PS), high impact polystyrene (HiPS), acrylonitrile-styrene resin (AS), acrylonitrile-butadiene-styrene resin (ABS), polycarbonate (PC) Etc. can be mentioned. The soft plastic of the lid 3 may be polyethylene, polypropylene, or the like.

[0028]

[Effect of device]

 As described above, according to the closed container with the lid of the present invention, there is an excellent effect that the leakage of juice can be surely prevented.

In particular, in the third invention, since the sealed state is obtained on both the inside and outside of the peripheral wall of the body, the leakage prevention effect becomes remarkable. In addition, even after the opening, even if the edge piece is cut off and the connection between the upper and lower annular protrusions and the annular groove is lost, the leakage is prevented by the annular fins. Can be used with confidence.

Further, in the fourth invention, the lid edge is formed at the time of opening, though it is formed into a rectangular shape so as not to take up a lot of space when arranging it during transportation or storage. It is very convenient to handle because the end of the piece can be cut securely along the upper annular groove.
