(A) is a B-part detailed sectional view in FIG. 3, (b) is a C-part detailed sectional view in FIG.

  Hereinafter, the present invention will be described more specifically with reference to the drawings.

  A cup container with a lid according to an embodiment of the present invention will be illustrated and described in detail with reference to FIGS. 1 to 4. In the specification, claims, abstract, and drawings, the upper side in FIG. 1A is the upper side, and the lower side is the lower side, based on the erected state of the container.

  As shown in FIG. 1A, in the cup container 100 with lid material according to the present embodiment, a body portion 11 forming a storage space S of contents and a not-shown bottom portion closing the lower end of the body portion 11 The inner lid 30 supported by the bottomed cylindrical container body 10 having a bottom, the bent portion 15 (see FIG. 1 (b)) which is a supporting portion formed on the trunk portion 11, and the inner lid 30 from above And a lid member 20 for closing the upper opening 18 (see FIG. 1 (b)) of the container body 10.

  The container main body 10 can be made of, for example, a synthetic resin mainly made of polypropylene (PP). In addition, the container body 10 may be formed to be thin by injection molding, for example, but may be formed by sheet molding.

  If necessary, a shrink label may be attached to the outer peripheral surface of the body portion 11, or a label may be integrally provided on the outer peripheral surface of the body portion 11 using a method such as in-mold molding (IML: Insert Molding Laminate). Thus, a decorated structure can be provided. In addition, by using a label having a barrier property to oxygen, the oxygen barrier property of the container can be enhanced.

  As shown in FIG. 1A and the like, the container body 10 has a bottomed cylindrical shape in which the diameter of the body portion 11 gradually decreases toward the lower side, and has a substantially circular shape in plan view There is. A flange portion 13 extends radially outward at the upper end portion of the body portion 11, and a lid member 20 described later is fixed to the flange portion 13 by means such as heat welding, etc. The top opening 18 of 10 is closed.

  Below the flange portion 13, as shown in FIG. 1 (b), there is formed a bent portion 15 which is bent radially inward toward the lower side. As shown in FIG. 1B, the outer peripheral portion of the inner lid 30 is in contact with the upper surface (radially inner side surface) of the bending portion 15, whereby the inner lid 30 is attached to the trunk 11 of the container main body 10. It is supported. That is, the bending portion 15 functions as a support portion of the inner lid 30.

  The shape of the support portion is not limited to the form of the bent portion 15 in FIG. 1B, and for example, the inner lid 30 may be a support projection or the like projecting radially inward from the inner peripheral surface of the trunk portion 11. It may be configured to be supported.

  On the inner peripheral surface of the upper end portion of the body portion 11 of the container body 10, a separation preventing protrusion 17 is formed to prevent the inner lid 30 from being unintentionally separated from the container body 10. The detachment preventing projection 17 further protrudes radially inward from the inner peripheral end of the flange portion 13 as shown in FIG. 1B, and the inner diameter thereof is formed smaller than the outer diameter of the inner lid 30 There is. In the present embodiment, the detachment preventing projection 17 is formed on the entire region in the circumferential direction of the container body 10. As a result, the inner lid 30 having an outer diameter larger than the inner diameter of the detachment preventing projection 17 undercuts and engages with the detachment preventing projection 17 and moves upward over the detachment preventing protrusion 17 in normal use. Can not do it. Therefore, detachment of the inner lid 30 can be suppressed.

  The detachment preventing projections 17 need not necessarily be formed over the entire area in the circumferential direction, and the detachment of the inner lid 30 is sufficiently suppressed if at least one place is provided within a half circumference of the circumferential direction. be able to.

  As shown in FIG. 1 (b), the outer cover of the inner lid 30 is undercut and engaged with the upper portion of the bending portion 15 of the trunk portion 11 and the lower portion of the detachment preventing protrusion 17. A pressing projection 19 for holding the inner lid 30 is formed.

  The inner lid 30 is held between the bent portion 15 and the pressing projection 19 as shown in FIG. 1 (b) in the initial state in which the lid 20 is not opened and the contents are not heated. . In the present embodiment, the pressing projections 19 are formed at only one place in the circumferential direction of the container main body 10, and the pressing projections 19 are formed at circumferential positions opposed to FIG. Absent. Therefore, when the pressure in the accommodation space S is increased by heating the contents as described later, the circumferential lid 30 is provided with the pressing projection 19 shown in FIG. 1B. Although the upward displacement is restricted, the upward displacement of the inner lid 30 is not restricted at other circumferential positions. For this reason, a part of inner cover 30 is lifted by the positive pressure in accommodation space S by heating of the contents. That is, in this embodiment, the circumferential position (the position without the pressing projection 19) lifted by the positive pressure in the accommodation space S and the circumferential position (the position where the pressing projection 19 is provided) are intended. I am making it. As a result, only a part of the inner lid 30 is lifted, so it is easier to lift the inner lid 30 more easily than lifting it while maintaining the entire inner lid 30 parallel to the bottom of the container body 10. A gap can be secured. And since steam can be released from the crevice between inner lid 30 and body part 11 which were displaced upwards, the pressure which rose by heating of the contents can be released.

  In the present embodiment, although the pressing projection 19 is formed at only one circumferential direction, the present invention is not limited to this aspect, and the inner lid 30 is lifted upward by the positive pressure in the housing space S, It is sufficient if the steam inside can be released to the outside. Further, the pressing projection 19 may not be formed.

  The inner lid 30 extends in the horizontal direction as shown in FIG. 1A, and the flange portion 35 supported by the container body 10 by its outer peripheral portion abutting the barrel portion 11 of the container body 10, and the flange portion A convex portion 33 extending upward from the inner peripheral end of 35 and having an inverted U shape in a front view and an annular shape in a plan view, a side wall 31 extending downward from an inner peripheral side of the convex portion 33, and a side wall 31 And a knob 37 having an inverted U-shape projecting upward at the radial center of the horizontal wall 32. At a height position slightly above the center of the side wall 31, stack portions 39 for stacking when the inner lid 30 alone is stored, transported, etc. are provided at a plurality of locations at regular intervals in the circumferential direction. As a result, when the middle lids 30 are stacked, the side walls 31 of the inner middle lid 30 are prevented from being firmly fitted to the side walls 31 of the outer middle lid 30.

  A housing portion 38 is constituted by the side wall 31 of the inner lid 30 and the horizontal wall 32 closing the lower end of the side wall 31. In the storage portion 38, contents different from the contents stored in the storage space S of the container main body 10 can be stored. For example, when coffee is stored in the storage space S of the container main body 10, cream etc. mixed with coffee can be stored in the storage portion 38 of the inner lid 30. In addition, when the soup is accommodated in the container body 10, the accommodation portion 38 of the inner lid 30 can accommodate ingredients such as vermicelli to be mixed with the soup. Furthermore, in the case of containing two different kinds of medicines used by being mixed with each other in the lidded cup container 100, one medicine is accommodated in the container body 10 together with water and the other medicine is accommodated in the inner lid 30 It can also be housed in section 38. Further, a spoon, a chopstick or the like for using the contents contained in the container main body 10 may be accommodated in the accommodation portion 38 of the inner lid 30.

  In the present embodiment, in the state before the lid 30 is fixed to the container main body 10, as shown by the two-dot chain line in FIG. It is formed to extend to the upper side beyond the upper end portion (the upper surface of the flange portion 13). Then, when the lid member 20 is fixed to the flange portion 13 of the container main body 10 by heat welding or the like, the lid member 20 presses the convex portion 33 of the inner lid 30 downward, the inner lid 30 is shown in FIG. As shown by the solid line, the convex portion 33 is elastically deformed so as to have substantially the same height as the flange portion 13. The lower surface of the flange portion 35 of the inner lid 30 abuts firmly on the bent portion 15 by the pressing force from the lid member 20. Therefore, when the lid member 20 is unopened, the inner lid 30 and the container body 10 It regulates that it leaks outside through the crevice of. In addition, the pressing force from the lid 20 can suppress the contents in the housing space S from entering the housing portion 38 of the inner lid 30.

  In the present embodiment, the convex portion 33 of the inner lid 30 is formed so as to extend over the upper end portion of the trunk portion 11 of the container main body 10 in a state before the lid member 20 is fixed to the container main body 10. Although, it is not limited to this aspect. The convex portion 33 may extend upward to at least the same height as the upper end portion of the body portion 11, whereby the convex portion 33 and the lid member 20 can be in close contact with each other to seal the housing space S. .

  The lid member 20 is formed of an oxygen barrier sheet using aluminum in the present embodiment. That is, as the lid member 20, for example, a paper or a resin material is used as a base material, and an aluminum layer may be used, or an aluminum sheet may be used. However, the present invention is not limited to this aspect, and the lid member 20 may be formed by adopting another configuration such as a laminated sheet made of synthetic resin. Further, as a method of fixing the lid member 20 to the container main body 10, for example, heat welding can be used, but it is not limited to this embodiment, and other means such as pressure bonding or adhesion may be used.

  When using the contents contained in the lid-equipped cup container 100 configured as described above, the user can start the lid from the state shown in FIGS. 1 (a) and 1 (b) before heating the contents. While picking up the outer peripheral portion of the material 20, it is pulled upward and peeled off from the container body 10. Although the pressing force from the lid 20 to the inner lid 30 is released by this, the pressure in the housing space S is not increased before the heating of the contents, so the contents are the container body 10 and the inner lid 30. It does not fly from the gap with The state of the cup container 100 with a lid at this time is shown in FIG.

  Next, the user heats the contents in the accommodation space S from the state of FIG. 2 using a heater or a microwave oven. The state of the cup container 100 with lid material when the content is heated to a temperature at which the contents boil and the pressure in the storage space S rises is shown in FIG. As shown in FIG. 4A, at the circumferential position where the pressing projection 19 is formed, which is indicated by “B” in FIG. 3, the outer peripheral portion of the flange portion 35 of the inner lid 30 is still a bent portion It is hold | maintained between 15 and the protrusion 19 for holding | suppressing, and the displacement to upper direction is controlled. On the other hand, at a circumferential position where the pressing projection 19 is not formed, as shown by "C" in FIG. 3, as shown in FIG. 4B, the flange portion 35 of the inner lid 30 is a two-dot chain line. The positive pressure in the accommodation space S is lifted upward from the position before heating shown in FIG. As a result, the inner lid 30 is inclined, and a gap is generated between the flange portion 35 of the inner lid 30 and the body portion 11 of the container body 10. Therefore, even if the contents are heated to a boiling state, as shown by an arrow in FIG. 4B, the vapor can be gradually released from the gap to the outside, so the pressure in the storage space S is excessive. To prevent the contents from scattering. In addition, when the user uses the contents, the flange portion 35 is deformed inward in the radial direction by pinching the side portion of the knob portion 37 of the inner lid 30, so that the engagement with the detachment preventing projection 17 is As a result, the inner lid 30 can be easily removed from the container body 10. In the present embodiment, the knob 37 is formed so that the direction perpendicular to the paper surface is the longitudinal direction rather than the lateral direction in FIGS. 2 and 3, and the user can easily pick the knob 37 with a finger. It is done. Further, the projection height of the knob portion 37 is lower than the projection height of the side wall 31. That is, the knob 37 is located inside the housing 38. The knob 37 may not be provided.

  As described above, in the cup container 100 with lid material of the present embodiment, the bottomed cylindrical shape having the body portion 11 forming the accommodation space S of the contents and the bottom portion closing the lower end of the body portion 11 The inner lid 30 is provided with a container body 10, an inner lid 30 supported by a support formed on the body 11, and an inner lid 30 covering the inner lid 30 from above and closing the upper opening 18 of the container main body 10; In the state where the lid member 20 is not attached, the projection portion 33 is configured to have a convex portion 33 extending upward to at least the height of the upper end portion of the trunk portion 11. By this, before the lid member 20 is opened, the accommodation space S is sealed by the lid member 20 and the convex portion 33 of the inner lid 30 to suppress leakage of the contents, and the lid member 20 is opened. When heating, the vapor is released from the gap between the inner lid 30 and the container body 10, so that the pressure rise in the housing space S can be suppressed, and the scattering of the contents can be suppressed.

  Further, in the present embodiment, the convex portion 33 is configured to extend above the upper end portion of the trunk portion 11 in a state in which the lid member 20 is not attached. By this, by pressing the middle lid 30 with the lid member 20 before the lid member 20 is opened, it is possible to more reliably suppress the leakage of the contents. In addition, the pressing force from the lid 20 can suppress the contents in the housing space S from entering the housing portion 38 of the inner lid 30.

  Further, in the present embodiment, since the bending portion 15 formed in the trunk portion 11 and bent downward in the radial direction is made to function as a support portion, the container body 10 can be easily supported when it is formed. The part can be formed.

  Further, in the present embodiment, the convex portion 33 is configured to have an annular shape formed concentrically with the container main body 10. As a result, since the inner lid 30 is uniformly pressed in the circumferential direction, the gap between the inner lid 30 and the container main body 10 is more reliably eliminated before the lid member 20 is opened, and the leakage of the contents is suppressed. be able to.

  Further, in the present embodiment, on the inner peripheral surface of the body portion 11 above the support portion, the separation preventing protrusion 17 which is in an undercut engagement with the outer peripheral portion of the inner lid 30 is provided. As a result, even if the pressure in the storage space S increases when the contents are heated and the cover 30 moves upward, the inner cover 30 does not move over the detachment preventing projection 17 and move upward. Therefore, the inner lid 30 can be reliably suppressed from being detached from the container body 10.

  Further, in the present embodiment, at least one portion of the detachment preventing projection 17 is formed within a half circumference of the circumferential direction of the trunk portion 11. As a result, even if the inner lid 30 is lifted in any direction in the circumferential direction, the inner lid 30 always abuts on the detachment preventing projection 17, so that the detachment of the inner lid 30 can be more reliably suppressed.

  Further, in the present embodiment, between the support portion by undercutting engagement with the outer peripheral portion of the inner lid 30 above the support portion (bent portion 15) of the trunk portion 11 and below the detachment prevention protrusion 17 Thus, the pressing projection 19 for holding the inner lid 30 is provided in a part of the circumferential direction. By this, when the content is heated and the pressure in the accommodation space S is increased, the inner lid 30 is inclined with the circumferential direction position where the pressing projection 19 is formed as a fulcrum, and between the container body 10 and the inner lid 30 Create gaps in the That is, since the inner lid 30 is intentionally inclined with the pressing projection 19 as a fulcrum by the positive pressure in the accommodation space S, a gap can be easily formed between the container body 10 and the inner lid 30. . And a steam can be escaped from the crevice, and a pressure rise in accommodation space S can be controlled. Therefore, scattering of the contents can be suppressed.

  Further, in the present embodiment, the pressing projection 19 is formed at one place in the circumferential direction of the trunk portion 11. Thus, when the contents are heated and the pressure in the storage space S is increased, the fulcrum at which the inner lid 30 tilts and the circumferential position to be lifted are more easily determined. Can be suppressed to suppress the pressure rise in the accommodation space S.

  Moreover, in this embodiment, it comprised so that the knob part 37 which has reverse U shape and protrudes upwards may be formed in the radial direction center of the inner cover 30. As shown in FIG. As a result, the user can pinch the side of the knob 37 to easily release the engagement with the detachment prevention protrusion 17 and lift it upward, and the inner lid 30 can be removed.

  Further, in the present embodiment, even after the lid 20 is removed and the container body 10 is opened, the upper opening 18 can be easily closed by the inner lid 30, so the inner lid 30 is accommodated in the container body 10. The contents can be prevented from spilling out to facilitate carrying of the lidded cup container 100 after opening.
