[1 First embodiment]
[1-1 Configuration]
(Lid body)
As will be described later with reference to FIG. It is used. Therefore, the lid 1 is formed so as to be able to form a joint region R that is joined to the upper edge 103 of the container 101 having the opening 102 . In addition, the lid 1 forms a state of being attached to the upper edge portion 103 (a state of being joined to the upper edge portion 103) so as to cover the opening portion 102 in a state of being joined to the opening portion 102 of the container 101. It is formed into a shape that allows As shown in FIG. 1, the lid 1 has a joint region R that is joined to an upper edge portion 103 formed on the upper end side of the opening 102 of the container 101 . FIG. 1 is a diagram showing an embodiment of the lid 1. As shown in FIG. As the container 101, a container having flexibility at the edge of the opening 102 is more preferably used. However, these do not prohibit the container 101 from being a container such as a metal container that has little or almost no flexibility.

(Material of lid)
Although the material of the lid 1 is not particularly limited, it is preferably a paper-based material. As the paper-based material, a raw material sheet made of so-called paper or pulp-based fiber, etc., which is obtained by making a sheet by drawing a slurry of fiber raw material on a net, drying or press-drying, and making paper, is pulverized with a pulverizer. Manufactured by agglutinating plant fibers and other fibers such as so-called air-laid sheets obtained by piling up open fiber raw materials such as crushed pulp by air flow and fixing the fibers of the pile with a binder. In addition to the so-called papers that are used, chemical fiber paper, synthetic paper, waterproof paper, coated paper, alternative paper, parchment paper, wool paper, glass fiber paper, stone paper, ceramic paper, etc., and laminated sheets of these mentioned. In addition, the paper-based material may be made of pulp alone, or may include non-pulp natural fibers, synthetic fibers, recycled fibers, etc., but preferably contains 50% by mass or more of pulp. , more preferably 70% by mass or more, more preferably 80% by mass or more, and particularly preferably 100% by mass of pulp. The paper-based material can be a synthetic resin or natural resin film or non-woven fabric, a wood-based material such as wood foil, or a composite material with a material such as aluminum foil. The content of pulp as a whole is preferably 50% by mass or more, and particularly preferably 80% by mass or more. The higher the pulp content, the easier it is for the paper-based material to biodegrade, which is preferable.

In addition, it is preferable that the lid body 1 is entirely formed of the paper-based material described above. Therefore, it is preferable that at least the main body 2 is made of a paper-based material. However, this does not prohibit that a part or the whole is formed of a material different from the paper-based material. For example, the lid 1 may have the main body 2 formed of a laminate of a paper-based material and a resin film material. In this case, the cover 1 can be attached to the container 101 by appropriately using a sealing method such as a pressing method, a heat sealing method, or an ultrasonic welding method with the surface of the main body 2 on which the film material is arranged facing the container 101 side. It becomes easy to join to. In consideration of these points, the lid 1 is also preferably used for a laminate containing a paper-based material. As for the main body 2, a laminate containing a paper-based material is also preferably used.

The lid 1 includes a main body 2 as shown in FIGS. 1A, 1B, and the like. In the lid 1 , the main body 2 includes the joint region R. As shown in FIG. 1A and 1B are a plan view and a cross-sectional view, respectively, showing one of other embodiments of the lid 1. FIG.

The joint region R is formed on the surface of the lid 1 when the lid 1 is attached to the upper edge 103 specified as the part in the outward direction from the edge 106 formed at the upper end of the opening 102 of the container 101. The area of the surface facing the opening 102 that is joined to the upper edge 103 is shown. Also, in the lid body 1 , a portion of the main body 2 that forms the joint region R is called a joint region corresponding portion 8 . In the example of FIGS. 1A and 1B, the joint region R corresponds to a region formed in a generally annular shape along the opening 102 of the container 101 in a shape corresponding to the opening 102 . Further, in this case, the joining region corresponding portion 8 is defined as an annular portion including the joining region R. As shown in FIG. If the joint regions R between the lid 1 and the container 101 are not continuously joined, the part sandwiched between adjacent joint regions R is also included in the joint region corresponding portion 8 .

The width of the bonding region R (the width along the medial-lateral direction) (that is, the width of the bonding region corresponding portion 8) is usually equal to or narrower than the width of the upper edge portion 103 of the opening 102. be. However, this does not prohibit the width of the junction region R from being wider than the width of the upper edge portion 103 of the opening 102 . Also, the joint region R may be formed inside the outer peripheral edge 71 of the main body 2 or may be formed up to the outer peripheral edge 71 of the main body 2 .

In the plan view of the lid 1 (that is, in the plan view of the main body 2), the inner edge of the joint area R (that is, the inner edge 8A of the joint area corresponding portion 8) extends from the edge of the opening 102 in the example of FIG. Although it is positioned slightly outside, this is just an example, and it may be positioned significantly outside from directly above the edge 106 of the opening 102 or may be positioned directly above the edge 106 of the opening 102 . However, it may also be inside the area directly above the edge 106 of the opening 102 . 1A and 1B, the lid 1 is viewed from above with the direction from the +Z side to the −Z side along the Z-axis direction as the line of sight. . The plan view of the main body 2 is also defined as the case where the main body 2 is viewed with the direction from the +Z side to the −Z side as the line of sight direction, as in the plan view of the lid body 1 .

Note that, in a plan view of the lid 1, the region inside the joint region R in the main body 2 is sometimes referred to as an inner region Rn. In addition, the top of the joint area R indicates the upper surface side (exposed surface 70 side) of the portion of the lid body 1 corresponding to the joint area R in plan view of the lid body 1 .

(Body)
The main body 2 covers the opening 102 and the upper edge 103 of the container 101 when the lid 1 is attached on the opening 102 of the container 101, as shown in FIG. 1A. The main body 2 has a portion corresponding to the joint region R (joint region corresponding portion 8), and an inner portion composed of an outer portion 72 including the joint region R and a portion inside from an inner edge 72A of the outer portion 72. 73. Regarding the inside and outside directions, the direction from the center CT of the main body 2 to the outside is defined as the outside direction, and the direction from the outer peripheral edge 71 of the main body 2 to the center CT is defined as the inside direction.

(outer part)

(inner part)
The inner side of the joint region R (that is, the inner side of the joint region corresponding portion 8) in plan view of the lid 1 indicates the portion forming the inner side of the portion forming the joint region R of the lid 1. . This portion is called an inner portion 73 .

(first part and second part)
Body 2 comprises a first portion 3 and a second portion 4 . In the example of FIG. 1 , a boundary portion 5 formed by the boundary between the first portion 3 and the second portion 4 has a guide portion 6 and a hinge portion 7 . A combination of the guide portion 6 and the hinge portion 7 can form a displacement-facilitating structure that facilitates rotation of the first portion 3 .

(first part)
The first portion 3 is defined as a portion of the main body 2 that is rotated upward so as to expose the opening 102 while the main body 2 is joined to the upper edge 103 of the container 101. indicates Here, the rotation of the first portion 3 indicates that the first portion 3 is displaced so as to rotate about a hinge portion 7 described later. When the first portion 3 rotates, the shape of the first portion 3 may be deformed. Rotating the first portion 3 upward can be realized, for example, by pulling up the first portion 3 . Although the shape of the first portion 3 is not particularly limited, in the example shown in FIG. Also, in this example, the first portion 3 is formed in the inner portion 73 (that is, the inner side of the joint region corresponding portion 8).

(second part)
A second portion 4 indicates a portion of the body 2 excluding the first portion 3 .

(boundary)
In the main body 2, a boundary portion 5 indicates a portion defined as a boundary between the first portion 3 and the second portion 4 in the non-rotating state. The non-rotating state refers to a state of the main body 2 in which rotation of the first portion 3 with respect to the second portion 4 is restricted. For example, the non-rotating state is a state in which the first portion 3 is not rotated when the lid 1 is not in use.

(guide part and hinge part)
The boundary portion 5 has a guide portion 6 and a hinge portion 7 .

The hinge portion 7 is defined by a portion that serves as a rotation axis of the first portion 3 when forming the upwardly displaced state. Note that the upwardly displaced state is a state of the main body 2 in which the first portion 3 is rotated upward (in the example of FIG. 1B, the +Z side displacement direction, +F direction) with respect to the second portion 4. identified. Note that rotating the first portion 3 upward means that the first portion 3 corresponds to the horizontal plane (in the example of FIG. 1A, the upper surface (exposed surface 70) of the main body 2), and is rotated along the X axis and the Y axis. (corresponding to the stretched XY plane), in addition to the case where the first part 3 is rotated in the plane direction of the plane that intersects the horizontal plane obliquely. A case of rotating in a direction along is also included.

The guide 6 defines the position at which the separation of the first part 3 and the second part 4 is intended to occur when forming the upwardly displaced state. The guide part 6 is defined as a part defining a position intended to cause the separation of the first part 3 and the second part 4 when forming an upwardly displaced state.

(Information department)
In the example of FIGS. 1A and 1B, the guide portion 6 is separated from the hinge portion 7 with the ends of the hinge portion 7 (one end portion 7A, the other end portion 7B) of the boundary portion 5 as base ends. specified as the portion extending in the direction In this example, one end 6A of the guide portion 6 is connected to one end 7A of the hinge portion 7, and the other end 6B of the guide portion 6 is connected to the other end 7B of the hinge portion 7. Further, the guide portion 6 is formed in a convex shape in a direction away from the hinge portion 7, has a front end portion 6C, and extends linearly (curved). However, this is only an example, and the shape of the guide portion 6 is not limited to a convex shape, and the guide portion 6 may be formed in a state different from the linear (curved) shape shown in FIG. 1A. .

(Positional relationship between guide part and joining area)
In the example of FIG. 1A, the guide portion 6 is formed inside the joint region R, that is, formed in the inner portion 73 . The guide part 6 can be a part where a separation structure between the first part 3 and the second part 4 is formed when the first part 3 is rotated with respect to the second part 4. .

(Positional relationship between guide part and opening)
Further, in the example of FIG. 1A, the guide portion 6 is positioned slightly inside from directly above (+Z direction side) the edge 106 of the opening 102 of the container 101 in a state where the lid 1 is joined to the container 101. is formed to be However, this is only an example, and at least part of the guide portion 6 may be positioned directly above the edge 106 of the opening 102, or may not be along the edge 106, and the guide portion 6 may be , in a plan view of the lid 1, it may be positioned significantly inside the edge 106 of the opening 102, but when the first portion 3 is rotated downward to form a downwardly displaced state, the first From the viewpoint of facilitating contact of the portion 3 of 1 with the inner peripheral surface 104A of the container 101, it is preferably located directly above the edge 106 of the opening 102 or outside the edge 106 thereof.

Although the structure of the guide portion 6 is not particularly limited, it has a weakened structure as described above. However, this does not restrict that the guide portion 6 has a structure other than the cut structure. For example, the guide part 6 may have a cut structure.

In this specification, the notch structure refers to a slit-like structure penetrating from the non-opposing surface (exposed surface 70) to the opposite surface (back surface) of the opening 102 when the lid 1 is attached to the container 101. Shows the penetrating structure. A weakened structure refers to a structural portion, such as a perforated structure or a half-cut structure, which requires less force to displace than a portion not provided with the structure. The perforation structure indicates a structure in which notches penetrating from the exposed surface 70 to the back surface and continuous portions avoiding the notches are alternately formed. The half-cut structure indicates a structure (partially cut structure) in which a partially cut part is formed while avoiding penetration in the thickness direction of the material forming the main body 2 . In the half-cut structure, the depth of the cut into the material forming the main body 2 is not particularly limited.

The guide part 6 may have a partially different structure. For example, a half-cut structure may be formed in the vicinity of the front end portion 6C of the guide portion 6, and a cut structure may be formed in other portions. When the vicinity of the front end portion 6C of the guide portion 6 is positioned at the joint region corresponding portion 8, even if the entire guide portion 6 has a cut structure, the first portion 3 may be unintentionally opened. It is suppressed by the joint structure (joint portion 151 ) with the lid 1 .

(hinge part)
As shown in the examples of FIGS. 1A and 1B, the boundary portion 5 has hinge portions 7 . In this example, the ends 7A, 7B of the hinge portion 7 are connected to the ends 6A, 6B of the guide portion 6, respectively. The structure of the hinge portion 7 is not particularly limited as long as it is other than the cut structure, and may be a non-formed structure or a weakened structure. A non-formed structure shall indicate a portion in which the formation of the incision structure and the weakened structure is omitted. In other words, the non-formation structure referred to here indicates that the main body 2 is configured so that the hinge portion 7 becomes conspicuous when the first portion 3 is rotated upward or downward.

When using the lid 1, the first portion 3 is raised with respect to the second portion 4. - 特許庁At this time, while the first portion 3 and the second portion 4 are separated from each other generally along the guide portion 6, the first portion 3 rotates with respect to the second portion 4 about the hinge portion 7 as an axis. stand up. The hinge portion 7 preferably forms a weakened structure from the viewpoint of smoothly forming the separation portion of the first portion 3 and the second portion 4 . However, this is only an example, and the hinge portion 7 may be of a non-formed structure as described above.

(Positional relationship between hinge part and joint area)
In the example of FIG. 1A, the hinge portion 7 is formed inside the joint region R, that is, formed on the inner portion 73 . However, this is only an example, and at least one end (7A, 7B) of the hinge portion 7 may be formed directly above the joint region R in plan view of the lid 1, or may be formed outside the joint region R. may be formed in

(Positional relationship between hinge and opening)
Also, in the example of FIG. 1A, the ends 7A and 7B of the hinge portion 7 are positioned slightly inside the position directly above the edge 106 of the opening 102 of the container 101 when the lid 1 is joined to the container 101. is formed to be However, this is only an example, and at least one end (7A, 8B) of the hinge portion 7 may be formed directly above the edge 106 of the opening 102, or may be formed outside the edge 106 directly above the edge 106. position. The ends 7A and 7B of the hinge portion 7 facilitate contact of the first portion 3 with the inner peripheral surface 104A of the container 101 when the first portion 3 is rotated downward to form a downwardly displaced state. From a point of view, it is preferable to be located directly above the edge 106 of the opening 102 or outside the edge 106 in plan view of the lid 1 .

(Exposed mouth)
As shown in FIG. 2, when the first portion 3 is displaced (upwardly displaced state), an exposure opening 10 that exposes the space 105 from the opening 102 is formed. According to the lid 1, when the lid 1 is attached to the opening 102 of the container 101 into which liquids such as beverages and miso soup are poured into the space 105, the user can easily open the exposed opening 10 of the lid 1. can be used as a drinking port to ingest the liquid inside the container 101 .

(downward displacement state)
The body 2 is configured to be able to form a downwardly displaced state, as shown in FIGS. 1B and 2 . Here, the downwardly displaced state refers to the state of the main body 2 in which the hinge portion 7 is used as a rotation axis and is downward from the second portion 4 (in the example of FIG. direction) in which the first portion 3 is pushed down (a state in which the first portion 3 is rotated downward). Rotating the first portion 3 downward means moving the first portion 3 to a horizontal plane (in the example of FIG. 1A, it also corresponds to the upper surface (exposed surface 70) of the main body 2 and corresponds to the XY plane). In addition to the case of rotating in the plane direction of a plane that intersects perpendicularly with respect to the horizontal plane, the case of rotating the first portion 3 in the plane direction of a plane that obliquely intersects the horizontal plane is also included. In the example of FIGS. 1A and 1B, when the first portion 3 is rotated downward, the first portion 3 rotates in the −F direction with the hinge portion 7 as the rotation axis.

When the first portion 3 of the main body 2 is pushed downward so that the first portion 3 closes the exposure opening 10 again after the first portion 3 is rotated to the upwardly displaced state, the second Part 3 of 1 is returned to the position corresponding to the non-rotated state. Further, by pushing the first portion 3 downward, the first portion 3 is pushed further downward than the second portion 4 with the hinge portion 7 as the rotation axis. In particular, when the entire lid body 1 has a structure including a paper-based material, the main body 2 also includes a paper-based material, so that the first portion 3 can be bent. , a state in which the first portion 3 is pushed further downward than the second portion 4 can be formed in a state in which the first portion 3 is bent downward.
