Description

The present invention relates to a container with a lid in which the opening of a container with a lid in which an container such as food such as instant noodles is previously stored is closed by joining with a sheet-shaped lid, and in particular, the sheet-shaped lid is once closed to the container body. The present invention relates to a container with a lid and a lid holder for a container with a lid, which can keep the lid closed even after being peeled off from the container.

Generally, as a container with a lid, for example, in the case of a container with a lid containing instant noodles which are foods as an container, the container with a lid has an opening made of resin such as foamed styrol or paper. It is configured to include a bottomed tubular container body and a sheet-shaped lid that is joined to and closed to the opening end face forming the opening of the container body. Instant noodles are stored in the container body in advance, and the lid is detachably adhered to the opening end face forming the opening by means such as an adhesive or a heat seal.

Then, when eating the stored instant noodles, the lid is peeled off while pulling up the knob of the lid protruding outward, the opening is partially opened, and hot water is poured from this opening to cook. I try to eat after the required time. In this case, if the lid is left open, heat will escape and the heating efficiency will be poor. Therefore, during cooking, rejoin the lid to the open end face and fold the knob to fasten the lid to the container body. To. However, if the picked portion is folded, the left and right portions of the picked portion will inevitably open, and sufficient heat retention cannot be achieved.

In order to solve this, conventionally, the lid which has been published in Japanese Patent Publication No. 61-147758 (Patent Document 1) and Japanese Patent No. 5936253 (Patent Document 2) and once peeled off is opened in the container body. A lid retainer has been proposed that holds the lid firmly in a closed state. This lid retainer is formed in a C shape in which elastically deformable plastic is fitted to the outside of the opening forming the opening of the container body, and a groove is formed inside to press the outer edge of the lid against the opening end surface of the container body. It is configured. Then, in the case of the above-mentioned instant noodles, after adding hot water, the lid is joined to the opening end face again, and in this state, the lid retainer is fitted to the outside of the opening forming the opening of the container body, and the outside of the lid is formed. The edge is pressed against the open end face of the container body.

By the way, this conventional lid holder is not originally provided in a container with a lid, so we will prepare it separately, but since it is made of C-shaped plastic, it will be bulky and inconvenient to handle. There was a problem that it became. Further, since it is made of plastic, it has a problem that it has poor adhesion to the container body and the lid, and liquid leakage is likely to occur when the container body is to be moved.
The present invention has been made in view of this point, and an object of the present invention is to provide a container with a lid, which is provided with a lid holding function so as not to be bulky. Another object of the present invention is to provide a lid holder for a container with a lid so as not to be bulky.

The container with a lid of the present invention for achieving such an object includes a bottomed cylindrical container body having an opening and a sheet-shaped lid that joins and closes the opening end face forming the opening of the container body. In a container with a lid
A lid retainer that presses the lid against the container body in a closed state is provided.
The lid retainer is made of an elastic sheet material that can be expanded and contracted, and is smaller than the area surrounded by the outer edge of the opening of the container body when viewed from a plane, and from the outer edge along the outer edge of the opening of the container body and the outer edge. It is formed with an inner edge inside, and the outer edge side is fixed to the surface of the lid.
The inner edge is extended to the outer edge side and inverted, and the inner edge is adhered to the outer surface of the opening side of the container body so that the joint portion between the container body and the lid can be covered.

It is desirable that the outer edge of the lid retainer has a length corresponding to at least (1/2) circumference or more of the entire circumference of the opening edge of the container body.
As a result, before opening the lid, the lid retainer is made of an elastic sheet material and is fixed to the surface of the lid, so that it does not become bulky.
Then, when opening the lid, a part or all of the lid is peeled off from the opening end surface forming the opening of the container body. In this case, since the lid retainer is made of an elastic sheet material and is fixed to the surface of the lid, it bends and moves in accordance with the lid, so that the lid can be opened as before without being bulky.

Then, when closing the once peeled lid again, the lid is joined to the open end surface of the container body, and in this state, the inner edge of the lid retainer is manually pulled toward the outer edge side to extend and invert it, and this inner edge is turned over to the container. It adheres to the outer surface on the opening side of the main body. As a result, the joint between the container body and the lid is covered with the lid retainer. In this case, it is only necessary to pull the inner edge of the lid retainer by hand to invert it, so that the work can be performed extremely easily. In this state, the outer edge side of the lid retainer is fixed to the surface of the lid, and the inner edge is adhered to the outer surface of the opening side of the container body, and the lid retainer is formed of an elastic sheet. Due to the elastic force, the adhesion to the container body and the lid is extremely improved, and the lid can be reliably pressed against the container body in the closed state.

In particular, in the case of the above-mentioned container with a lid containing instant noodles, after adding hot water, the lid is rejoined to the open end face, and in this state, the lid retainer functions, but with the open end face of the container body. Even if there is a gap with the lid and hot water or steam tries to leak from this gap, the lid holder is in the shape of an elastic sheet and covers the gap between the open end face of the container body and the lid, so hot water or steam leaks. It is prevented from coming out, and the heat retention can be surely improved. Further, for example, it is extremely useful because it can surely prevent liquid leakage when it is moved to the outside after putting hot water in a convenience store or the like.

When removing the lid again, the inner edge of the lid retainer may be pulled outward by hand to extend it, and the lid may be removed from the container body and the lid may be peeled off from the opening end surface forming the opening of the container body. In this case as well, the lid retainer is made of an elastic sheet material and is fixed to the surface of the lid, so that it bends and moves in accordance with the lid, so that the lid can be opened as before without being bulky. ..

Then, if necessary, when the thickness of the elastic sheet material is T, T = 0.01 mm to 0.1 mm. Since it is thin, it is possible to further prevent bulkiness.

Further, if necessary, the outer edge side of the lid retainer along the outer edge of the opening of the container body is attached to the lid. Adhesion can be performed by an adhesive or a welding means such as welding. As a result, the lid retainer can be attached to the lid and attached by simply attaching the elastic sheet in a state where no load is applied, so that the manufacturing can be easily performed.

In this case, the lid retainer is formed with a through hole, and all or part of the opening edge of the through hole is formed as an inner edge, and the outer edge is the same as the opening outer edge forming the opening of the container body. It is effective that the peripheral surface portion formed in a shape and formed between the outer edge and the inner line parallel to the outer edge by a predetermined dimension is attached to the lid. Since the outer edge has the same shape as the outer edge of the opening that forms the opening of the container body, it can be evenly arranged. When the entire opening edge of the through hole is used as the inner edge, the presser can be made uniform and secure over the entire circumference of the lid.

Further, if necessary, the inner edge is formed in an arc shape in cross section. It is also possible to make a substantially circular cross section thicker than the thickness of the general part. It can process terminals and is less likely to tear when pulled by hand.

Furthermore, if necessary, when the maximum width of the inner edge formed by the through hole is L, the configuration is such that 6 mm ≦ L. The shape of the through hole may be set to an appropriate shape such as a rectangular shape, a polygonal shape, a circular shape, an elliptical shape, or a star shape. In that case, if 6 mm ≦ L, it is possible to easily put a hand and improve the operability. Desirably, 30 mm ≦ L.

Further, in order to achieve the above object, the lid retainer for a container with a lid of the present invention is in the form of a sheet that is joined to and closed to a bottomed tubular container body having an opening and an opening end surface forming the opening of the container body. In the lid holder for a container with a lid that presses the lid of the container with a lid provided with the lid against the container body in a closed state.
It is made of a stretchable circular elastic sheet material whose area surrounded by the outer edge when viewed from a plane is smaller than the area surrounded by the outer edge of the opening of the container body, and a circular through hole coaxial with the outer edge in the center. Formed into a ring shape,
At the time of extension, the outer edge portion is adhered to the outer surface on the opening side of the container body, and the inner edge portion is adhered to the surface on the outer edge side of the lid so that the joint portion between the container body and the lid can be covered. The configuration is as follows.

That is, the lid retainer for a container with a lid of the present invention is a separate type from the container with a lid, unlike the attached type attached to the container with a lid. In terms of the positional relationship at the time of mounting, the inner edge portion of the separate type corresponds to the outer edge of the above-mentioned attached type, and the outer edge portion of the separate type corresponds to the inner edge of the attached type. However, since the outer edge side of the attached type is fixed to the lid, the fixed portion does not expand and contract, but in the separate type, both the outer edge portion and the inner edge portion expand and contract.

Specifically, this ensures that the lid retainer for the lidded container is always separate from the lidded container. It is okay to fit it in the container body. Since the lid holder for the container with a lid is made of an elastic sheet material, it does not become bulky.

When this is used, a part or all of the lid of the container body with a lid is opened, the once peeled lid is closed again, and the lid is used when the lid is joined to the open end surface of the container body. At this time, the outer edge of the lid retainer is pulled by hand to extend in the radial direction and adheres to the outer surface on the opening side of the container body, and the inner edge formed by the through hole is the surface on the outer edge side of the lid. To adhere to. In this case, the inner edge also extends. As a result, the joint between the container body and the lid is covered with the lid retainer. In this case, it is only necessary to pull the outer edge of the lid retainer by hand to cover it, so that the work can be performed extremely easily. In this state, the outer edge portion of the lid retainer is adhered to the outer surface on the opening side of the container body, and the inner edge portion is adhered to the surface on the outer edge side of the lid. Therefore, the lid retainer is formed of an elastic sheet. Therefore, due to this elastic force, the lid can be reliably pressed against the container body in the closed state.

In particular, in the case of the above-mentioned container with a lid containing instant noodles, after adding hot water, the lid is rejoined to the open end face, and in this state, the lid retainer functions, but with the open end face of the container body. Even if there is a gap with the lid and hot water or steam tries to leak from this gap, the lid holder is in the shape of an elastic sheet and covers the gap between the open end face of the container body and the lid, so hot water or steam leaks. It is prevented from coming out, and the heat retention can be surely improved. Further, for example, it is extremely useful because it can surely prevent liquid leakage when it is moved to the outside after putting hot water in a convenience store or the like.

When removing the lid again, the outer edge of the lid retainer may be pulled by hand to extend in the radial direction, removed from the container body, and the lid may be peeled off from the opening end face forming the opening of the container body. Since there is no lid retainer from the lid, the lid can be opened as before.

Then, if necessary, the outer edge portion and the inner edge portion are formed in a circular arc shape in cross section. It is also possible to make a substantially circular cross section thicker than the thickness of the general part. It can process terminals and is less likely to tear when pulled by hand.

In this case, when the thickness of the elastic sheet material is T, T = 0.01 mm to 0.1 mm, and when the diameters of the arcs of the outer edge portion and the inner edge portion are d, d = 0.5 mm to 3 mm. It is effective to set it to.
The strength of the outer edge portion and the inner edge portion is increased, and the outer edge portion and the inner edge portion are easily caught when pulled by hand, so that the operability can be improved.

Further, in order to achieve the above object, the lid retainer for a container with a lid of the present invention is in the form of a sheet that is joined to and closed to a bottomed tubular container body having an opening and an opening end face forming the opening of the container body. In the lid holder for a container with a lid that presses the lid of the container with a lid provided with the lid against the container body in a closed state.
It is formed in a cylindrical shape with opening edges at both ends, and is made of a stretchable elastic sheet material having a circumference smaller than the circumference of the opening outer edge of the container body.
At the time of extension, one of the opening edges is adhered to the outer surface of the container body on the opening side, and any one of the opening edges is adhered to the surface of the lid on the outer edge side, so that the container body is attached. The structure is such that the joint between the lid and the lid can be covered.

That is, the lid retainer for the container with a lid of the present invention is also a separate type from the container with a lid, and is always separate from the container with a lid, as described above. It is okay to fit it in the container body. Since the lid holder for the container with a lid is made of an elastic sheet material, it does not become bulky.

When this is used, a part or all of the lid of the container body with a lid is opened, the once peeled lid is closed again, and the lid is used when the lid is joined to the open end surface of the container body. At this time, the lid retainer is pulled by hand to extend in the radial direction, one of the opening edges is adhered to the outer surface of the opening side of the container body, and the other of the opening edges is the surface of the outer edge side of the lid. To be adhered to. As a result, the joint between the container body and the lid is covered with the lid retainer. In this case, it is only necessary to pull the lid holder by hand to cover it, so that the work can be performed extremely easily. In this state, the elastic force of the lid retainer allows the lid to be reliably pressed against the container body in the closed state.

In particular, in the case of the above-mentioned container with a lid containing instant noodles, after adding hot water, the lid is rejoined to the open end face, and in this state, the lid retainer functions, but with the open end face of the container body. Even if there is a gap with the lid and hot water or steam tries to leak from this gap, the lid holder is in the shape of an elastic sheet and covers the gap between the open end face of the container body and the lid, so hot water or steam leaks. It is prevented from coming out, and the heat retention can be surely improved. Further, for example, it is extremely useful because it can surely prevent liquid leakage when it is moved to the outside after putting hot water in a convenience store or the like.

When removing the lid again, the lid holder may be pulled by hand to extend in the radial direction, removed from the container body, and the lid may be peeled off from the opening end face forming the opening of the container body. Since there is no lid retainer from the lid, the lid can be opened as before.

Then, if necessary, the opening edges at both ends are formed in the shape of an arc in cross section. It is also possible to make a substantially circular cross section thicker than the thickness of the general part. It can process terminals and is less likely to tear when pulled by hand.

In this case, when the thickness of the elastic sheet material is T, T = 0.01 mm to 0.1 mm, and when the diameter of the arcs of the opening edges at both ends is d, d = 0.5 mm to. It is effective to set it to 3 mm.
In addition to increasing the strength of the opening edge portion, it becomes easier to get caught when pulled by hand, and operability can be improved.

Hereinafter, the container with a lid according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIGS. 1 to 6, the container C with a lid according to the embodiment is a so-called cup noodle in which instant noodles, which are foods, are contained as an container W. The container C with a lid according to this embodiment is joined to a bottomed cylindrical container body 1 having a circular opening 2 and an inverted truncated cone shape, and an opening end surface 3 forming the opening 2 of the container body 1. It is provided with a sheet-shaped circular lid 10 that is closed.

The container body 1 is formed of a resin such as Styrofoam, paper, or the like, and a ring-shaped flange 4 projecting outward is integrally formed on the opening edge, and the upper surface of the flange 4 is configured as the opening end surface 3. .. Instant noodles (container W) are stored in the container body 1 in advance.

Further, the lid 10 is formed in a sheet shape from paper, resin, a composite thereof, or the like, and is detachably adhered to the opening end surface 3 by means such as an adhesive or a heat seal. A knob portion 11 for facilitating the peeling of the lid 10 is integrally projected on the lid 10.

The container C with a main lid is provided with a lid retainer 30 that presses the lid 10 against the container body 1 in a closed state. The lid retainer 30 is made of a stretchable elastic sheet material, is smaller than the area surrounded by the opening outer edge 6 (outer edge of the flange 4) of the container body 1 when viewed from a plane, and is smaller than the area surrounded by the opening outer edge of the container body 1. It is formed with an outer edge 32 along the edge 6 and an inner edge 33 inside the outer edge 32, and the outer edge 32 side is fixed to the surface of the lid 10. All or part (all in the embodiment) of the opening edge of the through hole 31 of the lid retainer 30 is configured as the inner edge 33. Specifically, the lid retainer 30 is made of a stretchable elastic sheet material having a through hole 31 having a size smaller than the opening 2 of the container body 1 in the center, and protrudes from the outer edge 12 of the lid 10. The outer edge 32 side is fixed to the surface of the lid 10 so as not to be attached to the lid 10. As a result, in the lid retainer 30, the inner edge 33 formed by the opening edge of the through hole 31 is extended in the radial direction and inverted, and the inner edge 33 is the outer surface 5 (of the flange 4) on the opening 2 side of the container body 1. It is adhered to the lower outer surface 5) and is formed so as to be able to cover the joint portion between the container body 1 and the lid 10.

Examples of the elastic sheet material include natural rubber, synthetic rubber, and these latexes. Examples of the synthetic rubber include EPDM (ethylene propylene diene rubber), polyisoprene rubber, polybutadiene rubber, styrene-butadiene copolymer rubber, acrylonitrile-butadiene copolymer rubber, ethylene-propylene-diene copolymer rubber, and ethylene-. Examples thereof include propylene copolymer rubber, polychloroprene rubber, isobutylene-isoprene copolymer rubber, silicone rubber, and mixtures thereof. Further, for example, phenol resin, melamine resin, unsaturated polyester resin, epoxy resin, silicon resin, polyurethane resin and the like can be used. Further, polyethylene, nylon, polyvinyl chloride, polypropylene, polyester, polyamide and the like can also be used. Further, when the thickness of the lid retainer 30 is T, T = 0.01 mm to 0.1 mm is set.

More specifically, the outer edge 32 of the lid retainer 30 is formed in a circular shape having the same shape as the circular opening outer end edge 6 (outer edge of the flange 4) forming the opening 2 of the container body 1. In the embodiment, the lid retainer 30 is formed in a disk shape having the same outer diameter as the outer diameter of the lid 10, and is attached to the lid 10 by surface contact. Then, the peripheral surface portion 34 formed between the outer edge 32 and the inner line Q (two-dot chain line in FIG. 6) which is inside a predetermined dimension and is parallel to the outer edge 32 is anchored to the lid 10 with an adhesive, welding, or the like. It is attached by means and fixed to the lid 10. In the embodiment, the peripheral surface portion 34 is formed on the back surface side. As a result, the lid retainer 30 can be attached to and attached to the lid 10 simply by attaching an elastic sheet under no load, so that manufacturing can be easily performed.

The through hole 31 is formed by hollowing the center of the circular elastic sheet material in a circular shape concentric with the outer edge 32, and forming a plurality of triangular notches 35 from the hollowed portion to the outer edge 32 side at an equal angle. ing. In the embodiment, three notches 35 are formed. As shown in FIG. 6, when the maximum width of the inner edge 33 formed by the through hole 31 is L, 6 mm ≦ L is set. Desirably, 30 mm ≦ L. Further, the inner edge 33 formed by the through hole 31 is formed in an arc shape in cross section.

Therefore, according to the container C with a lid according to this embodiment, as shown in FIGS. 1, 4, and 6, the lid retainer 30 is made of an elastic sheet material before the lid 10 is opened, and the lid is formed. Since it is fixed to the surface of 10, it does not become bulky. Therefore, handling such as carrying can be performed as before. In particular, since the thickness T of the elastic sheet material is T = 0.01 mm to 0.1 mm, it is extremely thin, and therefore bulkiness can be further prevented.

When cooking instant noodles, first, as shown in FIG. 2, the lid 10 is opened and hot water is poured into the container body 1. When opening the lid 10, the lid 10 is peeled off from the opening end surface 3 forming the opening 2 of the container body 1 by holding the knob 11. For example, about half of the lid 10 is peeled off. In this case, since the lid retainer 30 is made of an elastic sheet material and is fixed to the surface of the lid 10, it bends and moves in accordance with the lid 10, so that the lid 10 can be opened as before without being bulky. be able to.

Then, leave the container body 1 with hot water for the required time. At this time, the lid 10 once peeled off is closed again, and the lid retainer 30 according to the embodiment is made to function. That is, as shown in FIGS. 3 and 5, the lid 10 is joined to the open end surface 3 of the flange 4 of the container body 1, and in this state, the inner edge 33 formed by the through hole 31 of the lid retainer 30 is pulled by hand. The inner edge 33 is adhered to the outer surface 5 on the opening 2 side of the container body 1 while being extended and inverted in the radial direction. In this case, since the inner edge 33 is formed in the shape of an arc in cross section, the terminal treatment is firm, it is difficult to tear when pulled by hand, and it can be reliably extended. Further, since the maximum width L of the inner edge 33 is 6 mm ≦ L, it is possible to easily put a hand and improve the operability.

As a result, the joint portion between the container body 1 and the lid 10 is covered with the lid retainer 30. In this case, since it is only necessary to manually pull the inner edge 33 formed by the through hole 31 of the lid retainer 30 to invert it, the work can be performed extremely easily. In this state, the outer edge 32 side of the lid retainer 30 is fixed to the surface of the lid 10, and the inner edge 33 is adhered to the outer surface 5 on the opening 2 side of the container body 1, so that the lid retainer 30 is an elastic sheet. Since it is formed of, the lid 10 can be reliably pressed against the container body 1 in the closed state by this elastic force. Therefore, the adhesion to the container main body 1 and the lid 10 is extremely improved, and the gap between the open end surface 3 of the container main body 1 and the lid 10 can be reliably closed. In particular, the outer edge 32 has the same shape as the opening outer edge 6 forming the opening 2 of the container body 1, and is formed between the outer edge 32 and the inner line Q which is inside a predetermined dimension and is parallel to the outer edge 32. Since the surface portion 34 is attached to the lid 10, the lid retainers 30 are evenly arranged, and the retainers can be made uniform and secure over the entire circumference of the lid 10.

Therefore, in the case of the container C with a lid containing instant noodles, there is a gap between the opening end surface 3 of the container body 1 and the lid 10, and even if hot water or steam tries to leak from this gap, hot water or steam can be used. The leakage of steam is prevented, and the heat retention can be surely improved. In addition, the adhesion to the container body 1 and the lid 10 is extremely improved, and liquid leakage can be reliably prevented when the container body 1 is to be moved. For example, it is extremely useful because it can surely prevent liquid leakage when moving out after putting hot water in a convenience store or the like.

Then, when eating the contained instant noodles, the lid 10 is removed. In this case, the inner edge 33 formed by the through hole 31 of the lid retainer 30 is pulled by hand to extend in the radial direction and removed from the container body 1, and the lid 10 is opened by the flange 4 forming the opening 2 of the container body 1. It may be peeled off from the end face 3. Also in this case, since the lid retainer 30 is made of an elastic sheet material and is fixed to the surface of the lid 10, it bends and moves in accordance with the lid 10, so that the lid 10 can be closed as before without being bulky. Can be opened.

7 and 8 show a container C with a lid according to another embodiment of the present invention. The container C with a lid has the same structure as the container body 1 as described above, but the structure of the lid retainer 30 is different. The lid retainer 30 is made of an elastic sheet material of the same material as above, which can be expanded and contracted, and is smaller than the area surrounded by the opening outer edge 6 (outer edge of the flange 4) of the container body 1 when viewed from a plane, and is a container. It is formed with an outer edge 32 along the outer edge 6 of the opening of the main body 1 and an inner edge 33 inside the outer edge 32, and the outer edge 32 side is fixed to the surface of the lid 10. A part of the lid retainer 30 is configured as an inner edge 33. In the embodiment, the lid retainer 30 is formed so as to cover substantially half of the side of the lid 10 where the knob portion 11 is located, and the outer edge 32 of the lid retainer 30 is the entire circumference of the open end edge 6 of the container body 1. Of these, the length corresponds to the opening edge 6 having at least (1/2) circumference or more. Further, it is formed in a symmetrical shape with respect to the center line P passing through the knob 11 when viewed from a plane, and the width M passing through the center line P is (2/3) of the radius of the opening edge 6 of the container body 1. ) It is formed to the above dimensions.

More specifically, the outer edge 32 of the lid retainer 30 is formed in an arc having the same shape as the circular opening outer edge 6 (outer edge of the flange 4) forming the opening 2 of the container body 1. The peripheral surface portion 34 formed between the outer edge 32 and the inner line Q (two-dot chain line in FIG. 8) which is inside a predetermined dimension and is parallel to the outer edge 32 is attached to the lid 10 by means of fastening such as adhesive or welding. It is attached and fixed to the lid 10. In the embodiment, the peripheral surface portion 34 is formed on the back surface side. As a result, the lid retainer 30 can be attached to and attached to the lid 10 simply by attaching an elastic sheet under no load, so that manufacturing can be easily performed.

A pair of handles 36 that can be grasped by hand are symmetrically formed on the inner edge 33. As a result, the inner edge 33 of the lid retainer 30 is extended and inverted toward the outer edge 32, and the inner edge 33 covers the outer surface 5 (lower outer surface 5 of the flange 4) of the container body 1 on the opening 2 side. It is put on and is formed so that the joint portion between the container body 1 and the lid 10 can be covered. Therefore, the same operation and effect as described above can be obtained by the container C with a lid according to this other embodiment.

Next, as shown in FIGS. 9 and 10, the lid retainer 40 for a container with a lid according to the embodiment of the present invention will be described. The same items as described above will be described with the same reference numerals. The lid retainer 40 has a bottomed tubular container body 1 having the same opening 2 as described above, and a sheet-shaped lid 10 joined to and closed to the opening end surface 3 forming the opening 2 of the container body 1. It is used for the conventional container with a lid Ca provided, and the lid 10 of the container with a lid Ca is pressed against the container body 1 in a closed state. Since the container body 1 and the lid 10 of the container Ca with a lid have the same configuration as described above, detailed description thereof will be omitted.

The lid retainer 40 is formed of a stretchable circular elastic sheet material, and a circular through hole 41 having a size smaller than the opening 2 of the container body 1 is formed in the center thereof, and is formed by an outer edge portion 42 and a through hole 41. It has a concentric inner edge portion 43, and the area surrounded by the outer edge portion 42 is smaller than the area surrounded by the opening outer end 6 forming the opening 2 of the container body 1 in a ring shape when viewed from a plane. It is formed. As a result, the outer edge portion 42 is adhered to the outer surface 5 on the opening 2 side of the container body 1 and the inner edge portion 43 is adhered to the surface of the lid 10 on the outer edge 12 side at the time of extension, so that the container body 1 and the lid 10 are attached. It is possible to cover the joint with. As the elastic sheet material, a material similar to the above can be used. The thickness T of the elastic sheet material is set to T = 0.01 mm to 0.1 mm in the same manner as described above. The inner edge portion 43 formed by the outer edge portion 42 and the through hole 41 is formed in an arc shape in cross section.

That is, the lid retainer 40 for a container with a lid of the present invention is a separate type from the container Ca with a lid, unlike the attached type attached to the container C with a lid. In terms of the positional relationship at the time of mounting, the inner edge portion 43 of the separate type corresponds to the outer edge 32 of the attached type, and the outer edge portion 42 of the separate type corresponds to the inner edge portion 43 of the attached type. However, since the outer edge 32 side of the attached type is fixed to the lid 10, it does not expand and contract, but in the separate type, both the outer edge portion 42 and the inner edge portion 43 expand and contract.

Therefore, the lid retainer 40 for the container with a lid is always separate from the container Ca with a lid. It does not matter if it is fitted in the container body 1. Since the lid retainer 40 for a container with a lid is made of an elastic sheet material, it does not become bulky. Therefore, it becomes easy to carry.

When this is used, for example, when the container Ca with a lid is used as a container W for instant noodles, which is a food product, in a so-called cup noodle container, it will be as follows. In the container Ca with a lid, the lid 10 of the container main body 1 is opened, the once peeled lid 10 is closed again, and the lid 10 is joined to the open end surface 3 of the container main body 1 in the same manner as described above.

The inner edge portion 43 formed by the through hole 41 is attached to the surface of the lid 10 on the outer edge 12 side. In this case, the inner edge portion 43 also extends. As a result, the joint portion between the container body 1 and the lid 10 is covered with the lid retainer 40.

In this case, it is only necessary to pull the outer edge portion 42 of the lid retainer 40 by hand to cover it, so that the work can be performed extremely easily. In this state, the outer edge portion 42 of the lid retainer 40 is adhered to the outer surface 5 on the opening 2 side of the container body 1, and the inner edge portion 43 is adhered to the surface of the lid 10 on the outer edge 12 side. Since the lid retainer 40 is formed of an elastic sheet, the lid 10 can be reliably pressed against the container body 1 in a closed state by this elastic force.

Therefore, in the case of the container Ca with a lid containing instant noodles, after adding hot water, the lid 10 is joined to the opening end surface 3 again, and in this state, the lid retainer 40 functions, but the container body 1 There is a gap between the opening end surface 3 and the lid 10, and even if hot water or steam tries to leak from this gap, the hot water or steam is prevented from leaking, and the heat retention can be reliably improved. In addition, the adhesion to the container body 1 and the lid 10 is extremely improved, and liquid leakage can be reliably prevented when the container body 1 is to be moved. For example, it is extremely useful because it can surely prevent liquid leakage when moving out after putting hot water in a convenience store or the like.

When removing the lid 10 again, the outer edge portion 42 of the lid retainer 40 is pulled by hand to extend in the radial direction to be removed from the container body 1, and the lid 10 is removed from the opening end surface 3 forming the opening 2 of the container body 1. It should be peeled off. Since the lid retainer 40 disappears from the lid 10, the lid 10 can be opened as before.

FIG. 11 shows a modified example of the lid retainer 40 for a container with a lid according to the embodiment of the present invention. This forms the outer edge portion 42 and the inner edge portion 43 in a circular arc shape in cross section, and makes the thickness T of the elastic sheet material T = 0.01 mm to 0.1 mm, and makes the arcs of the outer edge portion 42 and the inner edge portion 43. The diameter d is set to d = 0.5 mm to 3 mm. The strength of the outer edge portion 42 and the inner edge portion 43 is increased, and the outer edge portion 42 and the inner edge portion 43 are easily caught when pulled by hand, so that operability can be improved.

Next, as shown in FIGS. 12 and 13, the lid retainer 50 for a container with a lid according to another embodiment of the present invention will be described. The same items as described above will be described with the same reference numerals. The lid retainer 50 is used for the conventional container with a lid Ca as described above, and presses the lid 10 of the container with a lid Ca against the container body 1 in a closed state. Since the container body 1 and the lid 10 of the container Ca with a lid have the same configuration as described above, detailed description thereof will be omitted.

The lid retainer 50 has opening edges 51 and 52 at both ends and is formed in a cylindrical shape, and is a stretchable elastic sheet having a circumference smaller than the circumference of the opening outer edge 6 of the container body 1. It is made of a material, and at the time of extension, one of the opening edges 51 and 52 is adhered to the outer surface 5 on the opening 2 side of the container body 1, and the other of the opening edges 51 and 52 is the lid 10. It is adhered to the surface on the outer edge 12 side so as to be able to cover the joint portion between the container body 1 and the lid 10. Further, the opening edges 51 and 52 at both ends are each formed in an arc shape in cross section. It is also possible to make a substantially circular cross section thicker than the thickness of the general part. In the embodiment, when the thickness of the elastic sheet material is T, T = 0.01 mm to 0.1 mm is set, and when the diameters of the arcs of the opening edges 51 and 52 at both ends are d, d. = 0.5 mm to 3 mm is set.

That is, the lid retainer 50 is also a separate type from the container with a lid Ca, and is always separate from the container with a lid Ca. It does not matter if it is fitted in the container body 1. Since the lid retainer 50 for a container with a lid is made of an elastic sheet material, it does not become bulky. Therefore, it becomes easy to carry.

Therefore, when the lid retainer 50 is used, for example, when the container Ca with a lid is used as a container W for instant noodles, which is a food product, in a so-called cup noodle container, it will be described as follows. become. In the container Ca with a lid, the lid 10 of the container main body 1 is opened, the once peeled lid 10 is closed again, and the lid 10 is joined to the open end surface 3 of the container main body 1 in the same manner as described above. At this time, as shown in FIG. 13, the lid retainer 50 is used, and the lid retainer 50 is pulled by hand to extend in the radial direction, and one of the opening edges 51 and 52 is on the opening 2 side of the container body 1. It adheres to the outer side surface 5, and the other of the opening edges 51 and 52 adheres to the surface of the lid 10 on the outer edge 12 side.

In this case, it is only necessary to pull the lid retainer 50 by hand to cover it, so that the work can be performed extremely easily. Further, in this case, since the opening edge portions 51 and 52 have a cross section thicker than the thickness of the general portion, the strength of the opening edge portions 51 and 52 is increased, and the opening edges 51 and 52 are easily caught when pulled by hand, so that operability is operability. Can be improved.

In this state, the elastic force of the lid retainer 50 can reliably press the lid 10 against the container body 1 in the closed state. Therefore, in the case of the container Ca with a lid containing instant noodles, after adding hot water, the lid 10 is joined to the opening end surface 3 again, and in this state, the lid retainer 50 functions, but the container body 1 There is a gap between the opening end surface 3 and the lid 10, and even if hot water or steam tries to leak from this gap, the hot water or steam is prevented from leaking, and the heat retention can be reliably improved. In addition, the adhesion to the container body 1 and the lid 10 is extremely improved, and liquid leakage can be reliably prevented when the container body 1 is to be moved. For example, it is extremely useful because it can surely prevent liquid leakage when moving out after putting hot water in a convenience store or the like.
