[First Embodiment]
Hereinafter, the container according to the first embodiment and the cup lid constituting the container will be described with reference to the drawings.

As shown in FIG. 1, the container 100 includes a paper cup 10 having a container-like outer shape of a drink and a cup lid 20 covering the opening 10a thereof, and the entire container 100 is enclosed in a transparent shrink wrap 30. That is, the shrink wrap 30 wraps and fixes the paper cup 10 and the cup lid 20 so as to be integrated. The shrink wrap 30 keeps the inside of the container 100 in a good hygienic condition.

As shown in FIGS. 2B and 3B, the paper cup 10 is made of paper and has a body portion 12 having a tapered outer surface that narrows toward the lower end and a body portion 12 on the lower end side of the body portion 12. It has a fixed flat circular bottom paper 14. The lower end portion 12a of the body portion 12 is connected and joined to the bottom paper 14 to form a cylindrical shape or a hill shape. The body portion 12 and the bottom paper 14 are made of paper and are formed from a paper pattern obtained by punching out raw material paper. The body portion 12 and the bottom paper 14 may be formed by using paper as a base material, and may be formed by, for example, attaching a resin film to one side or the inner side surface. A print area PA1 is provided on the side surface of the body portion 12, but the print area PA1 is not essential.

As shown in FIGS. 2A and 2B, the cup lid 20 is detachably set on the mouth portion 10b of the paper cup 10. The cup lid 20 has a substantially circular contour corresponding to the mouth portion 10b of the paper cup 10 in a plan view, and has a thin plate shape extending at substantially the same height position as the mouth portion 10b of the paper cup 10 in a side view. In the cup lid 20, the main portion appearing on the outside is the main body 28 having a contour shape substantially corresponding to the contour of the mouth portion 10b of the paper cup. The main body 28 is in a state of being placed on the upper end of the mouth portion 10b of the paper cup, and is attached so as to fit the four support convex portions 22 described later into the inside of the mouth portion 10b. The size of the main body 28 may be slightly larger than the inner diameter of the mouth portion 10b of the paper cup 10 as long as the support convex portion 22 can be fitted into the mouth portion 10b. The cup lid 20 is formed with thin bow-shaped recesses or gaps 20a at four locations on the outer circumference, and corresponds to the four supporting convex portions 22 for mounting. Further, the cup lid 20 is formed with a curved thin band-shaped expansion portion 24 at one position on the outer circumference. The expansion portion 24 extends to the outside of the outer peripheral contour CO1 of the main body 28. The expansion portion 24 is in a state of projecting to the outside of the mouth portion 10b of the paper cup 10 in the direction or the lateral direction of the XY plane on which the main body 28 extends, but is larger than the inner diameter of the mouth portion of the paper cup 10 and causes the shrink wrap 30. It suffices if it protrudes from the curl portion 31c of the paper cup 10 to the extent that it does not break.

The details of the cup lid 20 will be described with reference to FIGS. 4 (A) to 4 (C). The cup lid 20 is made of paper and is formed from a paper pattern obtained by punching out raw material paper. The cup lid 20 may be formed only of paper as long as it is formed of paper as a base material, but it can also be formed by sticking a resin film on the front and back surfaces. The cup lid 20 has a main body 28 having a contour shape close to a circle that substantially corresponds to the contour of the mouth portion 10b of the paper cup 10, and a substantially quadrangular 4 extending downward (−Z side) from four locations on the outer circumference of the main body 28. One support convex portion 22 and an arc-shaped expansion portion 24 formed between two adjacent support convex portions 22 on the outer circumference of the main body 28 and having a band shape and a constant width in the direction of the XY plane on which the main body 28 extends. Be prepared. There is no limitation on the length of the extension portion 24 in the circumferential direction, but it is not necessary for the function to be wider than the finger of the user to open the opening. A print area PA2 for providing information to the user is provided on the upper surface of the main body 28, but the print area PA2 is not essential.

The main body 28 is a flat plate-shaped portion. The four support convex portions 22 are foldably connected to the main body 28. Specifically, the four support convex portions 22 integrally extend downward from the main body 28 (Z direction parallel to the central axis of the paper cup 10), and the pattern including the main body 28 is formed on the four fold lines FL. It is bent at a right angle at a point. The four support convex portions 22 are formed in a four-equal arrangement, and are arranged so as to be offset from each other by 90 °. The four support convex portions 22 enable the cup lid 20 to be attached to the mouth portion 10b in a state of being aligned in a direction along the plane including the mouth portion 10b (direction parallel to the XY plane). In the illustrated example, the inclination angle α of the support convex portion 22 is set to be less than 90 °, but the inclination angle α can be appropriately set at around 90 °. When the inclination angle α is larger than 90 °, the cup lid 20 can be set on the paper cup 10 by bending the support convex portion 22 more and pushing the support convex portion 22, and the paper cup of the cup lid 20. It is possible to have a spring effect that stabilizes the fixation with respect to 10. The expansion portion 24 is an extension of the outer edge portion 28a of the main body 28 in a direction along a plane including the mouth portion 10b (a direction parallel to the XY plane), and the expansion portion 24 extends the main body 28 and the support convex to the paper cup 10. When the portion 22 is set, it projects outward from the outer periphery of the mouth portion 10b along a plane including the mouth portion 10b. The expansion portion 24 is a hooking portion 26 that receives an external force from a user's finger when the main body 28 is set in the paper cup 10 and the main body 28 is removed from the paper cup 10. That is, when the main body 28 is set in the paper cup 10, the expansion portion 24 slightly protrudes outward along the plane including the mouth portion 10b. Since the expansion portion 24 is a protrusion protruding to the outside of the mouth portion 10b of the paper cup 10, it is easy to put a user's finger on the expansion portion 24 to remove the cup lid 20. The width of the expansion portion 24 in the radial direction or the outward direction of the main body 28 is sufficient if the user's finger hangs on it, and by preventing the width of the expansion portion 24 from becoming excessively large, consideration is given to preventing damage to the shrink wrap 30. However, it is possible to prevent the size of the container 100 from becoming large.

FIG. 5A shows a pattern in which the cup lid 20 is unfolded. As shown in FIG. 4B, each support convex portion 22 is bent at a right angle along the crease line FL. With respect to the root portion 22a of each support convex portion 22, the original width W1 along the outer peripheral contour CO1 of the main body 28 is narrower than the interval W2 along the outer peripheral contour CO1 of the plurality of support convex portions 22. In this case, the work of fitting the plurality of support convex portions 22 into the mouth portion 10b of the paper cup 10 becomes easy, and the deformation of the periphery of the mouth portion 10b of the paper cup 10 can be suppressed by the plurality of support convex portions 22. As for the radial length of the support convex portion 22, it suffices as long as it stabilizes the fixing of the cup lid 20, and the radial length of the support convex portion 22 is the circumferential length of the support convex portion 22. It doesn't have to be longer.

FIG. 5B shows a side view in which the paper cup 10 is partially broken. The paper cup 10 is composed of a container portion 31 and an outer cylinder 32. The container portion 31 has a structure similar to that of a general paper cup in which the bottom paper 14 is fixed to the body paper 31a. The outer cylinder 32 constitutes a body portion 12 together with the body paper 31a, and is fixed to the body paper 31a at the upper end and the lower end. A space SP is formed between the outer cylinder 32 and the body paper 31a, making it difficult for heat from other materials of the boiling water filled in the paper cup 10 to be transmitted to the user's fingers. A curl portion 31c is formed at the upper end of the container portion 31 to form a mouth portion 10b. In the storage space CS in the paper cup 10, food and drink FD, which is a packaged or exposed ingredient and seasoning, is stored. A hot water supply instruction line LH is formed on the inner wall surface 31i of the container portion 31 as a shallow annular recess or protrusion. The protruding length D1 of the support convex portion 22 formed on the cup lid 20 shown by the virtual line is shorter than the height width D2 from the mouth portion 10b to the inner hot water supply instruction line LH. In this case, even if the cup lid 20 is refitted after pouring hot water into the paper cup 10, the support convex portion 22 can be prevented from being immersed in the hot water.

Returning to FIG. 2A, the outer peripheral contour CO1 of the main body 28 of the cup lid 20 is the portion of the paper cup 10 excluding the plurality of support convex portions 22 when the main body 28 is set in the paper cup 10. It fits inside the outer diameter of the curl portion 31c provided on the mouth portion 10b, and spreads to have substantially the same shape or more as the mouth portion 10b of the paper cup 10 or the top thereof. In this case, it is possible to prevent the cup lid 20 from entering the depth of the mouth portion 10b of the paper cup 10. In a specific example, the circle of the outer peripheral contour CO1 is set to the same size as the circle of the top TL of the curl portion 31c.

A method for manufacturing the container 100 shown in FIG. 1 and the like will be described. First, the paper cup 10 is prepared. The manufacturing method of the paper cup 10 is general, and description thereof will be omitted here. Next, the paper for the cup lid 20 is prepared, printed on the surface thereof, and punched into a contour shape as shown in FIG. 5A to obtain a paper pattern. After that, the support convex portion 22 of the paper pattern of the cup lid 20 is bent mechanically or manually and set in the mouth portion 10b so as to close the opening 10a of the paper cup 10 filled with the food and drink FD as the content. Finally, the connecting body of the paper cup 10 and the cup lid 20 is wrapped with the material of the shrink wrap 30, and the paper cup 10 and the cup lid 20 are wrapped and integrated by the shrink wrap 30 by heat adhesion, shrinkage, and fusing. Fix to. As a result, the container 100 is completed. At the time of use or opening, the user peels off the shrink wrap 30 so as to break it, and removes the cup lid 20 from the paper cup 10. After that, hot water is poured into the ingredients of the food and drink FD and the cooking is completed. At this time, the cup lid 20 may be refitted into the paper cup 10, but the mouth portion 10b of the paper cup 10 may be left open.

In the cup lid 20 of the first embodiment described above, when the cup lid 20 covers the mouth portion 10b of the paper cup 10, a plurality of convex portions come into contact with the mouth portion 10b of the paper cup 10 and the cup lid 20 is used. The work of aligning the main body 28 in the direction along the plane including the mouth portion 10b of 20 and setting the cup lid 20 on the main body 28 becomes easy. Further, when the cup lid 20 is removed from the paper cup 10, the main body 28 is separated from the mouth portion 10b by putting a finger on the hook portion 26, so that the cup lid 20 can be easily separated from the mouth portion.

[Second Embodiment]
Hereinafter, the container according to the second embodiment and the cup lid constituting the container will be described. The cup lid or the like according to the second embodiment is a partially modified version of the cup lid or the like of the first embodiment, and the parts not particularly described are the same as those of the first embodiment.

6 (A) and 6 (B) are a plan view and a side view illustrating the container 100 of the second embodiment. The container 100 of the second embodiment is a modification of the main body 28 of the cup lid 20.

With reference to FIGS. 7 (A) to 7 (C), in the case of the second embodiment, the cup lid 20 has a recess function in the outer peripheral portion of the main body 28 instead of the expansion portion 24 shown in FIG. 2 (A) and the like. A part 25 is provided. The concave function portion 25 is surrounded by a pair of parallel cut lines 25i and 25j inside the outer peripheral contour CO1 of the main body 28, a crease line 25k connecting the roots thereof, and the cut lines 25i and 25j and the crease line 25k. It has a folding portion 25p.

When the user pushes the folding portion 25p with the fingertip FG, the recessed functional portion 25 changes from the state shown in FIG. 7 (A) to the state shown in FIG. 8 (A), and inward from the outer peripheral contour CO1 of the main body 28. It becomes a recessed recess 124. The recess 124 is a hooking portion 26 that receives an external force from a user's finger when the main body 28 is set in the paper cup 10 and the main body 28 is removed from the paper cup 10. The folded portion 25p has a role of preventing the inside of the paper cup 10 from being exposed through the recess 124 before removing the main body 28 from the paper cup 10.

FIG. 9 shows a paper pattern in which the cup lid 20 is unfolded. The four support convex portions 22 are formed in a four-equal arrangement on the outer periphery of the main body 28, and the concave functional portion 25 is formed between the two adjacent support convex portions 22.

The shape and size of the recessed function portion 25 shown in the drawing are merely examples, and the recessed function portion 25 having various shapes and sizes can be provided in the cup lid 20. That is, the recessed functional portion 25 can be provided not only in the outer peripheral portion of the main body 28 but also in the central portion, and can be provided in one or more places between the outer peripheral portion and the central portion of the main body 28.

In the present embodiment, the folding portion 25p is pushed in to form the recess 124, but the folding portion 25p can be omitted and the recess 124 can be provided in the main body 28 of the cup lid 20 from the beginning. In this case, the recess 124 without the folding portion 25p becomes the recess function portion 25.

[Third Embodiment]
Hereinafter, the container according to the third embodiment and the cup lid constituting the container will be described. The cup lid or the like according to the third embodiment is a partial modification of the cup lid or the like of the first embodiment, and the parts not particularly described are the same as those of the first embodiment.

FIG. 10A is a developed view of the cup lid 20 of the third embodiment. In this case, in the cup lid 20, three support convex portions 22 are formed in a three-equal arrangement on the outside of the substantially circular outer peripheral contour CO1 of the main body 28, and are arranged so as to be displaced from each other by 120 ° with respect to the center of the main body 28. Has been done. An extension portion 24 is formed as a hook portion 26 between two adjacent support convex portions 22. Each support convex portion 22 is bent at a right angle along the crease line FL, although not shown, when used. Even if there are three support convex portions 22, the workability of setting the cup lid 20 on the paper cup 10 does not change significantly, and the mounting stability of the cup lid 20 on the paper cup 10 is also good.

FIG. 10B is a developed view of the cup lid 20 which is a modification of the cup lid 20 shown in FIG. 10A. Also in this case, the cup lid 20 has three support convex portions 22 on the outside of the substantially circular outer peripheral contour CO1 of the main body 28. A concave function portion 25 is formed as a hook portion 26 between two adjacent support convex portions 22. Each support convex portion 22 is bent at a right angle along the crease line FL, although not shown, when used.

[Fourth Embodiment]
Hereinafter, the container according to the fourth embodiment and the cup lid constituting the container will be described. The cup lid or the like according to the fourth embodiment is a partially modified version of the cup lid or the like of the first embodiment, and the parts not particularly described are the same as those of the first embodiment.

FIG. 11 is a developed view of the cup lid 20 of the fourth embodiment. In this case, in the cup lid 20, two support convex portions 22 are formed on opposite sides of the main body 28 on the outside of the substantially circular outer peripheral contour CO1 of the main body 28, and 2 between the two support convex portions 22. An arc-shaped expansion portion 24 is formed at the location as a hook portion 26. Each support convex portion 22 is bent at a right angle along the crease line FL, although not shown, when used. When there are two support convex portions 22, the work of setting the cup lid 20 on the paper cup 10 becomes easy, and if the width of the support convex portion 22 in the circumferential direction is secured to some extent, the cup lid 20 is attached to the paper cup 10. The stability is also relatively good.

12 (A) and 12 (B) are a development view and a usage state diagram of the cup lid 20 which is a modification of the cup lid 20 shown in FIG. In this case, in the cup lid 20, two support convex portions 22 are formed on opposite sides of the main body 28 on the outside of the substantially circular outer peripheral contour CO1 of the main body 28, and 2 between the two support convex portions 22. An arc-shaped expansion portion 24 is formed at the location as a hook portion 26. Further, in the support convex portion 22, a pair of crease lines FL arranged at both ends and a crease line CL connecting the pair of crease lines FL are formed on the root side. As shown in FIG. 12B, when the support convex portion 22 is bent along the crease line FL, the expansion portion 424 corresponding to the inside of the crease line CL is in a state of protruding from the main body 28. That is, the expansion portion 424 is formed in the support convex portion 22, and when the support convex portion 22 is bent with respect to the main body 28, the expansion portion 424 projects outward (that is, outward in the radial direction of the main body 28). In this case, the two types of expansion portions 24,424, a total of four hooking portions 26, achieve support in the vertical direction of the cup lid 20 when the cup lid 20 is set, and when the cup lid 20 is removed. It suffices to grab one or more of the four hooking portions 26. Further, the support convex portion 22 and the expansion portion 424 are composite positioning members 404 that are used for both horizontal positioning and vertical positioning. In the composite positioning member 404, an expansion portion 424 is formed at a position where the support convex portion 22 aligns the main body 28 with the mouth portion 10b of the paper cup 10. The work of pulling away from 10b is stable.

In the example of FIG. 12A, two support convex portions 22 and two expansion portions 24 are provided, but instead of the expansion portion 24, a positioning member 404 including the support convex portion 22 and the expansion portion 424 is provided. You may. At this time, it is not necessary to provide the four positioning members 404, and three positioning members 404 or five or more positioning members 404 can be provided.

[Modifications and others]
Although the present invention has been described above in accordance with the embodiments, the present invention is not limited to the above-described embodiments and the like. For example, the cut line CL for bending the support convex portion 22 of the cup lid 20 with respect to the main body 28 can be various.

13 (A) to 13 (D) show a modified example of the crease line FL formed on the cup lid 20. The crease line FL for the support convex portion 22 shown in FIG. 13A is along the arc of the circumference corresponding to the contour of the main body 28. In this case, the restoring force of the support convex portion 22 becomes stronger after the support convex portion 22 is bent, and the stability of the set of the cup lid 20 with respect to the paper cup 10 is enhanced. The crease line FL for the support convex portion 22 shown in FIG. 13B is along the circumferential chord or arc corresponding to the contour of the main body 28, but is separated at the center. The crease line FL for the support convex portion 22 shown in FIG. 13 (C) includes a crease line FL along a circular arc or chord corresponding to the contour of the main body 28 and a crease line FL extending in a radial direction perpendicular to the arc. It is a composite. The crease line FL for the support convex portion 22 shown in FIG. 13 (D) also extends along the arc or chord of the circumference corresponding to the contour of the main body 28 and extends in the radial direction perpendicular to the arc or chord. It is a combination of and.

In the example shown in FIG. 14A, the support convex portion 22 is widened on the tip end side, and it can be said that the cup lid 20 is difficult to come off after the cup lid 20 is set on the paper cup 10. In the example shown in FIG. 14B, the width of the support convex portion 22 is narrowed on the tip side, and it can be said that the work of setting the cup lid 20 on the paper cup 10 becomes relatively easy.

In the example shown in FIG. 15, the plurality of support convex portions 622 are not housed inside the paper cup 10, but are exposed so as to surround the outer periphery of the upper end of the paper cup 10. In this case, the cup lid 20 can be positioned in the horizontal direction and the vertical direction with respect to the paper cup 10 by the plurality of support convex portions 622, and when the cup lid 20 is removed, one of the expansion portions 24 is used. All you have to do is grasp the above.

The example shown in FIG. 16 is a modification of the shape shown in FIG. 4 (A). In this example, the window WD is provided on the main body 28 of the cup lid 20. The arrangement, number, and shape of the illustrated window WD are merely examples, and can be appropriately changed depending on the application.

In the example shown in FIG. 17, as the shrink wrap 30, a strip-shaped one that covers only the upper end portion of the paper cup 10 and the outer peripheral portion of the cup lid 20 is added to ensure that the cup lid 20 is fixed to the paper cup 10. I have to. That is, the shrink wrap 30 does not have to cover the paper cup 10 and the cup lid 20 as a whole.

In the above, the case where the mouth portion 10b of the paper cup 10 is circular has been described, but the mouth portion 10b of the paper cup 10 may be quadrangular or elliptical.
