Description

[Technical Field]

[0001] The present invention relates to a lid holder for a container, such as a container for instant instant noodles, which has a cylindrical container body with a bottom that is open at the top end and has a flange formed at the top end, and a sheet-like lid that is attached to the edge of the top end of the container body and closes the opening at the top end of the container body, to prevent a part of the lid from opening when it is peeled off from the container body. [Background technology]

[0002] Conventionally, there has been known a fastener for a cup noodle lid that prevents a portion of the lid from peeling up after being peeled off from the container body while waiting for hot water to be poured into the instant cup noodle container (see, for example, Patent Document 1). The fastener described in Patent Document 1 is formed in a strip shape using a sheet-like flexible material. Slits are formed in two places on the fastener, and the portions where the slits are formed form flaps that can swing up and down. After hot water is poured into the cup noodle container body, the fastener described in Patent Document 1 is attached to the cup noodle container so that the flaps catch on a flange formed on the upper end of the container body.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-70262 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when purchasing instant cup noodles at a convenience store, it is common for a person to peel off a portion of the lid from the cup noodle container, pour hot water into the container, and then take the cup noodles home. Also, for example, instant cup noodles are sometimes used as a meal while hiking. In this case, after peeling off a portion of the lid from the cup noodle container and pouring hot water into the container, the cup noodle container may be placed on an unstable location such as a rocky area. If the cup noodle container tilts when being taken home from a store such as a convenience store or when placed on an unstable location such as a rocky area, the contents, such as hot water, will leak out of the container, even if the fixing device described in Patent Document 1 is attached to the cup noodle container.

[0005] Therefore, the object of the present invention is to provide a lid holder for holding a lid so that a part of the lid peeled off from the container body does not open, and which can prevent the contents such as hot water from leaking out of the container even if the container is tilted. [Means for solving the problem]

[0006] In order to solve the above problems, the lid holder of the present invention is a lid holder for a container having a bottomed, cylindrical container body that is open at the top end and has a flange formed at the top end, and a sheet-like lid that is attached to the edge of the top end of the container body and closes the opening at the top end of the container body, and is used to hold down the lid to prevent a part of the lid from opening when it is peeled off from the container body, and is characterized by having an annular ring portion that is positioned on the outer periphery of the flange, a lower abutment portion that is connected to the lower end of the annular portion and abuts against the underside of the flange, and an upper pressing portion that is connected to the upper end of the annular portion and is in close contact with at least the outer periphery of the top surface of the lid, pressing the lid toward the edge.

[0007] The lid retainer of this invention has a lower contact part that contacts the underside of the flange of the container body, and an upper pressing part that fits tightly against at least the outer periphery of the top surface of the lid and presses the lid toward the upper edge of the container body. Therefore, when the lid retainer of this invention is attached to a container, it is possible to prevent the contents, such as hot water, from leaking out of the container even if the container is tilted.

[0008] In the present invention, the lid holder is preferably made of flexible resin or rubber, which makes it easier to elastically deform the lid holder, making it easier to attach and detach the lid holder from the container.

[0009] In the present invention, the upper pressing portion is preferably formed in an annular shape and fits tightly against the top surface of the lid around the entire circumference, which effectively prevents the contents from leaking out of the container even if the container is tilted.

[0010] In the present invention, the lower abutment portion is preferably composed of a plurality of divided abutment portions spaced apart in the circumferential direction of the annular portion, and the divided abutment portions in the circumferential direction of the annular portion are preferably formed with notches. This configuration makes it easier to deform the lid retainer, thereby making it easier to attach and detach the lid retainer to and from the container.

[0011] In the present invention, the lid holder preferably has a tab that protrudes from the annular portion toward the outer periphery, which allows the tab to be grasped to attach or detach the lid holder from the container, thereby facilitating the attachment or detachment of the lid holder from the container.

[0012] In the present invention, the lower abutment portion is preferably composed of three divided abutment portions spaced apart in the circumferential direction of the annular portion, with notches between the divided abutment portions in the circumferential direction of the annular portion, with two of the three notches being located on either side of the tab in the circumferential direction of the annular portion, and the remaining notch being located between the tab and the center of the annular portion. This configuration makes it easier to deform the lid holder when grasping the tab to attach or detach the lid holder to or from a container. This makes it easier to attach or detach the lid holder to or from a container. [Effects of the Invention]

[0013] As described above, if the lid holder of the present invention is attached to a container, it is possible to prevent the contents, such as hot water, from leaking out of the container even if the container is tilted. [Brief explanation of the drawings]

[0014] [Figure 1] 1A is a perspective view of a lid holder according to an embodiment of the present invention attached to a container, and FIG. 1B is a bottom view of the lid holder shown in FIG. 1A. [Figure 2] 2 is a cross-sectional view of the upper portion of the container and the lid holder shown in FIG. 1(A). DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] (Configuration of the lid holder) Fig. 1(A) is a perspective view of a lid holder 1 according to an embodiment of the present invention attached to a container 4, and Fig. 1(B) is a bottom view of the lid holder 1 shown in Fig. 1(A). Fig. 2 is a cross-sectional view of the upper portion of the container 4 and the lid holder 1 shown in Fig. 1(A).

[0017] The lid holder 1 of this embodiment is attached to and used with a container 4 that includes a cylindrical container body 2 with a bottom that is open at the top and has a flange 2a formed at the top end, and a sheet-like (film-like) lid 3 that is attached to the edge 2b at the top end of the container body 2 and closes the opening at the top end of the container body 2. The container 4 of this embodiment is a container for instant cup noodles. The lid holder 1 is a tool for holding down the lid 3 on the container 4 so that a portion of the lid 3 that has been peeled off from the container body 2 does not open (does not curl up).

[0018] The container body 2 is formed from a resin such as polystyrene foam or paper. The container body 2 is formed in the shape of a truncated cone with a bottom. The outer and inner diameters of the container body 2 gradually increase toward the top. When viewed from above, the outer shape of the container body 2 is circular, and a circular opening is formed at the top end of the container body 2. The rim 2b is an annular flat surface surrounding the opening. The flange 2a widens from the top end of the container body 2 toward the outside in the radial direction of the container body 2. The flange 2a is formed in an annular shape.

[0019] The lid 3 is made of resin or paper. Alternatively, the lid 3 is made of a composite material of resin and paper, etc. The lid 3 is formed in a circular shape. The outer peripheral portion of the lid 3 is removably attached to the edge portion 2b by thermocompression bonding, etc. Before being peeled off from the container body 2, the lid 3 seals the upper end of the container body 2. The lid 3 has a tab 3a for peeling the lid 3 from the container body 2. The lid 3 in this embodiment has two tabs 3a.

[0020] The lid holder 1 is made of flexible resin or rubber. The lid holder 1 includes an annular portion 1a arranged on the outer periphery of the flange portion 2a. The annular portion 1a is formed in a circular ring shape. The annular portion 1a is also formed in a cylindrical shape with a very short axial length (see FIG. 2). The lid holder 1 is attached to the container 4 so that the axial direction of the annular portion 1a coincides with the up-down direction of the container 4. In the following description, for convenience, the axial direction of the annular portion 1a will be referred to as the "up-down direction," a predetermined direction perpendicular to the axial direction of the annular portion 1a will be referred to as the "front-to-back direction," the X1 direction in FIG. 1(B), which is one side of the front-to-back direction, will be referred to as the "front" side, and the X2 direction in FIG. 1(B), which is the opposite side of the front, will be referred to as the "rear" side. The Y direction in FIG. 1(B), which is perpendicular to the up-down direction and the front-to-back direction, will be referred to as the "left-to-right direction."

[0021] In addition to the annular portion 1a, the lid retainer 1 is equipped with a lower contact portion 1b that is connected to the lower end of the annular portion 1a and that contacts the underside of the flange portion 2a, an upper pressing portion 1c that is connected to the upper end of the annular portion 1a and that comes into close contact with at least the outer circumferential portion of the upper surface of the lid 3 to press the lid 3 toward the edge portion 2b, and a tab 1d that protrudes outward from the annular portion 1a. The lid retainer 1 of this embodiment is composed of the annular portion 1a, the lower contact portion 1b, the upper pressing portion 1c, and the tab 1d.

[0022] The knob 1d protrudes forward from the annular portion 1a. The knob 1d is formed in a flat plate shape with its thickness direction in the vertical direction. The knob 1d is connected to the lower end of the annular portion 1a. The upper pressing portion 1c is formed in an annular shape. Specifically, the upper pressing portion 1c is formed in a circular ring shape. Furthermore, the upper pressing portion 1c is formed in a flat plate shape with its thickness direction in the vertical direction. The upper pressing portion 1c extends from the upper end of the annular portion 1a toward the inside in the radial direction of the annular portion 1a. The upper pressing portion 1c is in close contact with the upper surface of the lid 3 (specifically, the upper surface of the outer peripheral portion of the lid 3) around the entire circumference of the lid 3.

[0023] The lower contact portion 1b is composed of a plurality of divided contact portions 1e, 1f that are spaced apart in the circumferential direction of the annular portion 1a. In this embodiment, the lower contact portion 1b is composed of one divided contact portion 1e and two divided contact portions 1f. That is, the lower contact portion 1b is composed of three divided contact portions 1e, 1f. The divided contact portions 1e, 1f are formed in an arc shape. The vertical cross-sectional shape of the divided contact portions 1e, 1f is hook-shaped (see Figure 2).

[0024] The split abutment portions 1e and 1f protrude downward from the annular portion 1a. Furthermore, the split abutment portions 1e and 1f extend slightly from the lower end of the annular portion 1a toward the inside in the radial direction of the annular portion 1a. The width of the split abutment portions 1e and 1f in the radial direction of the annular portion 1a is narrower than the width of the upper pressing portion 1c in the radial direction of the annular portion 1a. The split abutment portion 1e is connected to the front portion of the annular portion 1a. The split abutment portion 1e is located at the same position as the knob 1d in the circumferential direction of the annular portion 1a. One of the two split abutment portions 1f is connected to the right rear portion of the annular portion 1a, and the other split abutment portion 1f is connected to the left rear portion of the annular portion 1a.

[0025] A notch 1g is formed between the two divided abutment portions 1f in the circumferential direction of the annular portion 1a. A notch 1h is formed between the divided abutment portion 1e and the divided abutment portion 1f in the circumferential direction of the annular portion 1a, and the notch portions 1h are formed in two locations. The notch portions 1h are arranged on both sides of the tab 1d in the circumferential direction of the annular portion 1a. The notch portion 1g is formed in the rear portion of the annular portion 1a and is arranged in a position that overlaps with the tab 1d and the divided abutment portion 1e when viewed from the front-to-rear direction. In other words, the notch portion 1g is arranged so as to sandwich the center of the annular portion 1a between the tab 1d and the notch portion 1g.

[0026] A user of lid holder 1 peels off a portion of lid 3 (specifically, the portion on the side where tab 3a is formed) from container body 2, pours hot water into container body 2, and then attaches lid holder 1 to container 4. Specifically, lid holder 1 is attached to container 4 from above. At this time, tab 1d is used as a guide to attach lid holder 1 to container 4 so that tab 3a is positioned in the portion formed in cutout portion 1h. When lid holder 1 is attached to container 4, the upper surfaces of divided abutment portions 1e and 1f abut against the lower surface of flange portion 2a, and the lower surface of upper pressing portion 1c comes into close contact with the upper surface of lid 3 around the entire circumference, pressing the outer peripheral portion of lid 3 toward edge portion 2b.

[0027] (Main effect of this form) As explained above, in this embodiment, the lid holder 1 includes a lower contact portion 1b that contacts the underside of the flange portion 2a of the container body 2, and an upper pressing portion 1c that comes into close contact with the outer peripheral portion of the upper surface of the lid 3 and presses the lid 3 toward the edge portion 2b of the container body 2. Therefore, in this embodiment, if the lid holder 1 is attached to the container 4, it is possible to prevent the contents, such as hot water, from leaking out of the container 4 even if the container 4 is tilted. In particular, in this embodiment, the annular upper pressing portion 1c comes into close contact with the upper surface of the lid 3 around the entire circumference of the lid 3, so it is possible to effectively prevent the contents from leaking out of the container 4 even if the container 4 is tilted.

[0028] In this embodiment, the lid holder 1 is made of flexible resin or rubber, which makes it easy to elastically deform the lid holder 1. Also, in this embodiment, the lid holder 1 is provided with a knob 1d, which can be grasped to attach and detach the lid holder 1 to and from the container 4. Therefore, in this embodiment, the lid holder 1 can be easily attached and detached to and from the container 4.

[0029] Furthermore, in this embodiment, lower contact portion 1b is composed of three divided contact portions 1e, 1f, and notches 1g, 1h are formed between divided contact portions 1e, 1f in the circumferential direction of annular portion 1a, making it easier to deform lid holder 1. In particular, in this embodiment, notches 1h are located on both sides of tab 1d in the circumferential direction of annular portion 1a, and notch 1g is formed in the rear portion of annular portion 1a and is located between tab 1d and the center of annular portion 1a. This makes it easier to deform lid holder 1 when grasping tab 1d to attach or detach lid holder 1 to or from container 4. Therefore, in this embodiment, it is easier to attach or detach lid holder 1 to or from container 4.

[0030] (Other embodiments) In the above-described embodiment, the lower contact portion 1b may be composed of two divided contact portions. In this case, for example, in the above-described embodiment, the two divided contact portions 1f may be connected to each other without forming the notch portion 1g. Furthermore, if the number of knobs 3a of the lid 3 is one, in the above-described embodiment, the one divided contact portion 1f may be connected to the divided contact portion 1e without forming the one notch portion 1h. Furthermore, the lower contact portion 1b may be composed of four or more divided contact portions. Furthermore, in the above-described embodiment, the lower contact portion 1b may be formed in an annular shape connected in the circumferential direction of the annular portion 1a.

[0031] In the above-described embodiment, the upper pressing portion 1c may be formed in an arc shape. That is, the upper pressing portion 1c does not have to be formed in an annular shape. In this case, for example, when viewed from the top-bottom direction, the central angle of the arc-shaped upper pressing portion 1c with respect to the center of the annular portion 1a is 90° or more, and the upper pressing portion 1c is connected to more than half of the upper end portion of the annular portion 1a at the front side. Furthermore, the upper pressing portion 1c may be composed of multiple divided pressing portions arranged at intervals in the circumferential direction of the annular portion 1a.

[0032] In the above-described embodiment, the upper pressing portion 1c may be formed in a disk shape that covers the entire lid 3 from above. Even in this case, the upper pressing portion 1c adheres to at least the outer peripheral portion of the upper surface of the lid 3 and presses the lid 3 toward the edge portion 2b. In this case, an empty container formed by the container body 2 and the lid holder 1 can be reused as a container to be used in the event of a disaster, for example.

[0033] In the above-described embodiment, the lid holder 1 does not have to have the tab 1d. Also, in the above-described embodiment, the outer shape of the container body 2 when viewed from above may be a shape other than a circle. For example, the outer shape of the container body 2 when viewed from above may be a rectangle. In this case, the annular portion 1a and the upper pressing portion 1c are formed in a square annular shape corresponding to the outer shape of the container body 2. Furthermore, in the above-described embodiment, the container 4 may be something other than a container for instant cup noodles. [Explanation of symbols]
