Description

  The present invention relates to a container lid in which an interior member is mounted on an outer lid, and a medicine container including the container lid.

  More specifically, the present invention relates to an inner lid that contains a desiccant or the like inside the inner lid as an interior member, or a lid of a container having a packing attached to the outer lid, and the container containing the medicine is closed. As a result, the technology for maintaining the atmosphere in the container in a moisture-proof or humidity-controlled state, and the desiccant contained in the inner lid after use is easily separated and discarded. It is related to technology.

  Conventionally, in the case of storing, for example, a drug that dislikes moisture in a container, the mouth of the container is hermetically closed by a lid, and the desiccant is accommodated inside the lid so that the moisture absorption function of the desiccant is achieved. Alternatively, moisture control is performed to maintain the atmosphere in the container in a predetermined state by the humidity control function.

  In order to achieve such moisture-proofing, a packing is attached inside the outer lid, or a bottomed cylindrical inner lid is detachably attached inside the outer lid, and a desiccant is contained inside the inner lid. Is known. In the case where the inner lid is attached to the inner side of the outer lid, the atmosphere in the container is brought into contact with the desiccant by bringing the atmosphere in the container into contact with the desiccant through a vent hole penetrating the bottom wall of the inner lid. The moisture contained in the water is absorbed to prevent moisture.

  In addition, when all of the medicine stored in the container is consumed and the container is discarded, it is necessary to take out the desiccant from the inside of the inner lid because the desiccant is separated and discarded.

  Regarding such a container lid, a container lid 100 as shown in FIGS. 15, 16, 17, and 18 has been disclosed by the present applicant (Patent Document 1). Here, FIG. 15 is a partially omitted cross-sectional view of a conventional container lid 100, and FIG. 16 is a partially enlarged view of part A of FIG. 15, showing a state before the inner lid is attached to the outer lid. 17 is a partially enlarged view of part A in FIG. 15 and shows a state after the inner lid is attached to the outer lid. FIG. 18 is a partially enlarged view of part A in FIG. It is the figure which showed the state after fitting the outer cover with which was mounted | worn in the opening part of the container.

  In this specification, “upper” and “upper surface” mean the top wall side of the outer lid when the inner lid is attached to the inner side of the outer lid, and “lower” and “lower surface” mean the inner side of the outer lid. The bottom wall side of the inner lid when the inner lid is attached to.

  As shown in FIG. 15, the container lid 100 of this Patent Document 1 includes an outer lid 104 having a top wall 140, a peripheral wall 142 formed integrally with the top wall 140, and a bottom wall 128, An inner lid 102 having a bottom wall 128 and a peripheral wall 126 formed integrally therewith. The peripheral wall 142 of the outer lid 104 protrudes downward from the outer peripheral side position of the top wall 140, and the peripheral wall 126 of the inner lid 102 protrudes upward from the outer peripheral side position of the bottom wall 128.

  Further, the inner lid 102 is mounted on the inner side of the outer lid 104 from the distal end side of the peripheral wall 126, and is thereby surrounded by the top wall 140 of the outer lid 104, the peripheral wall 126 and the bottom wall 128 of the inner lid 102. A space 106 is formed, and a desiccant 108 is accommodated in the space 106. That is, the desiccant 108 is accommodated in the inner lid 102 attached to the inner side of the outer lid 104.

  Further, the outer lid 104 to which the inner lid 102 is attached is fitted into the mouth portion 152 of the container 105 containing the medicine, whereby the mouth portion 152 of the container 105 is closed.

  On the inner peripheral wall 142a of the outer lid 104, a threaded portion 143 that is screwed with the threaded portion 153 of the container 105 is formed, and on the top wall 140 side of the inner peripheral wall 142a, an annularly formed engaging convex portion 144 protrudes.

  An annular flange 130 is formed integrally with the peripheral wall 126 at the tip of the peripheral wall 126 of the inner lid 102 so as to project substantially horizontally toward the radially outer side. The annular flange 130 is formed with an inner circumferential annular convex portion 132 projecting upward from the inner circumferential side position of the annular flange 130 and an outer circumferential side annular convex portion 134 projecting upward from the outer peripheral side position. Yes. The tip of the inner peripheral annular convex portion 132 is positioned above the tip of the outer peripheral annular convex portion 134 in a state before the outer lid 104 to which the inner lid 102 is attached is fitted into the mouth portion 152 of the container 105. It is formed to do.

  Further, the annular flange 130 is formed with a plurality of engagement pieces 136, 136,... Projecting radially outward from the outer peripheral position. As shown in FIG. 16, the engaging piece 136 is substantially horizontal from the outer peripheral side position of the annular flange 130 toward the radially outer side in a state before the inner lid 102 is attached to the inner side of the outer lid 104. It is protruding.

  Further, as shown in FIG. 16, the length r1 ′ from the center line CL104 of the outer lid 104 to the base end of the engaging convex portion 144 is adjusted by aligning the center positions of the inner lid 102 and the outer lid 104. When the lid 102 is mounted on the inner side of the outer lid 104, the length from the center line CL 102 of the inner lid 102 to the tip of the engagement piece 136 is shorter than the length r 4 ′. In addition, the length r2 ′ from the center line CL104 of the outer lid 104 to the tip of the engaging convex portion 144 is aligned with the center position of the inner lid 102 and the outer lid 104, and the inner lid 102 is mounted inside the outer lid 104. In this case, the length is longer than the length r3 ′ from the center line CL102 of the inner lid 102 to the base end of the engagement piece 136.

  Then, as shown in FIG. 17, the inner lid 102 is placed on the inner side of the outer lid 104 so that the inner circumferential side annular convex portion 132 of the inner lid 102 contacts the lower surface 140 a of the top wall 140 of the outer lid 104. When attached, the plurality of engaging pieces 136, 136,... Of the inner lid 102 get over the engaging convex portion 144 and abut against the inner peripheral wall 142a of the outer lid 104 in a state of being elastically deformed. As a result, the outer lid 104 and the inner lid 102 are engaged with each other, and the inner lid 102 is held while being attached to the outer lid 104.

  In addition, as shown in FIG. 18, the inner lid 102 is attached to the inner side of the outer lid 104 so that the inner peripheral annular convex portion 132 of the inner lid 102 contacts the lower surface 140 a of the top wall 140 of the outer lid 104. Further, when the outer lid 104 to which the inner lid 102 is attached is fitted into the mouth portion 152 of the container 105, that is, the outer lid 104 in the state shown in FIG. 17 is fitted into the mouth portion 152 of the container 105.

JP 2009-40435 A Published practical use Showa 57-190761

  By the way, in the container lid 100 of Patent Document 1, since the engagement piece 136 protrudes substantially horizontally from the outer peripheral side position of the annular flange 130 toward the radially outer side, the inner lid 102 is placed on the inner side of the outer lid 104. In order for the engaging piece 136 to get over the engaging convex portion 144 when being mounted on, the engaging piece 136 needs to be largely elastically deformed. However, in order to greatly elastically deform the plurality of engagement pieces 136, 136,..., It is necessary to apply a large pushing force to the inner lid 102, so that the workability of mounting the inner lid 102 is inferior.

  In addition, when the inner lid 102 is attached to the inner side of the outer lid 104, if the pushing force is biased or if there is a dimensional error in the inner lid 102 or the outer lid 104, a plurality of engagement pieces 136, 136, Is over elastically deformed in an uneven manner over the engaging projection 144, and the inner lid 102 is engaged with the outer lid 104 in a tilted state. Further, when an impact is applied to the inner lid 102 and the outer lid 104 from the outside after the inner lid 102 is attached to the outer lid 104, the inner lid 102 may be engaged with the outer lid 104 in a tilted state. That is, as shown in FIG. 19, among the plurality of engagement pieces 136, 136,..., A certain engagement piece 136 a is restored to a substantially horizontal state and is in contact with the inner peripheral wall 142 a and is opposed to this. The engagement piece 136b is in contact with the inner peripheral wall 142a in a state of being greatly elastically deformed downward, and the inner lid 102 and the outer lid 104 are engaged with each other in a state of so-called misalignment.

  When the inner lid 102 and the outer lid 104 are engaged with each other with this misalignment, the inner peripheral annular convex portion 132 and the outer peripheral annular convex portion 134 and the lower surface 140a of the top wall 140 are all Since it did not contact | abut uniformly over the periphery, the problem that the airtightness of the container 105 will fall has arisen.

  Note that Patent Document 1 states that even when the center is slightly misaligned, the inner lid 102 is displaced so as to be aligned by fitting the outer lid 104 into the mouth portion 152 of the container 105. Are listed. However, if the engagement piece 136a shown in FIG. 19 is restored to a substantially horizontal state, it does not elastically deform even when a horizontal force is applied to the engagement piece 136a. It is difficult to return the plurality of engagement pieces 136, 136,... To a state of being elastically deformed evenly by fitting the outer lid 104 to which the is attached to the mouth portion 152 of the container 105.

  In order to cope with the above-described problems, the length of the engagement piece 136 is shortened and the rigidity of the engagement piece 136 is reduced so that the inner lid 102 can be mounted inside the outer lid 104 with a small pushing force. Can be considered. However, in this case, since the engagement force between the inner lid 102 and the outer lid 104 is also reduced, the bottom wall 128 of the inner lid 102 is torn off and the desiccant 108 is taken out from the inner lid 102. In addition, a new problem occurs that the inner lid 102 is removed.

  Further, as shown in FIG. 20, the public utility Showa 57-190761 includes an outer lid 204 having a top wall 240 and a peripheral wall 242, and an inner lid 202 having a bottom wall 228 and a peripheral wall 226. An engagement convex portion 244 projects from the inner peripheral wall 242a of the lid 204, and an annular flange 230 is formed at the tip of the peripheral wall 226 of the inner lid 202 so as to project diagonally downward toward the radially outer side. 200 is disclosed (Patent Document 2).

  In the container lid 200 of Patent Document 2, the annular flange 230 protrudes obliquely downward, so that the inner lid 202 can be easily attached to the inner side of the outer lid 204, and the inner lid 202 is not easily detached from the outer lid 204. Although it was constructed, no consideration was given to airtightness, and it could not be used as a lid for containers that required airtightness.

  The present invention has been made in view of such a conventional problem, and can be used to attach an interior member to the inside of an outer lid with a small pushing force, and the attached interior member is difficult to come off. It aims at providing the container for chemical | medical agent accommodation provided with the lid | cover and the lid | cover of this container.

Are arranged at equal intervals on the outer peripheral side position of the annular flange 30, and in this embodiment, 12 pieces are formed. In addition, as shown in FIG. 4, the engagement piece 36 is inclined diagonally from the outer peripheral side position of the annular flange 30 toward the radially outer side in a state before the inner lid 2 is attached to the inner side of the outer lid 4. It protrudes downward. Further, the shapes of the plurality of engagement pieces 36, 36,... Are formed so that the upper surface side is steeply inclined and gradually becomes thinner toward the distal end side so as to be easily elastically deformed downward. The thickness of the base end portion is about ½ of the thickness of the annular flange 30. The plurality of engagement pieces 36, 36,... Are all formed in the same shape.

  It should be noted that the number of the plurality of engaging pieces 36, 36,... May be at least a plurality, and can be set to an appropriate number depending on the shape of the container 5 and the lid 1. Also, the arrangement interval of the plurality of engagement pieces 36, 36,... Is not particularly limited, but when the inner lid 2 is mounted inside the outer lid 4, the plurality of engagement pieces 36, 36,. It is preferable that they are arranged at substantially equal intervals so as not to be elastically deformed and cause misalignment.

  Further, as shown in FIG. 4, the length r1 from the center line CL4 of the outer lid 4 to the proximal end of the engaging convex portion 44 matches the center positions of the inner lid 2 and the outer lid 4, and the inner lid When 2 is attached to the inside of the outer lid 4, it is configured to be shorter than the length r 4 from the center line CL 2 of the inner lid 2 to the tip of the engagement piece 36. Further, the length r2 from the center line CL4 of the outer lid 4 to the tip of the engaging projection 44 is aligned with the center positions of the inner lid 2 and the outer lid 4, and the inner lid 2 is mounted inside the outer lid 4. At this time, it is configured to be longer than the length r3 from the center line CL2 of the inner lid 2 to the base end of the engagement piece 36. That is, when the inner lid 2 is mounted on the inner side of the outer lid 4 so that the inner peripheral annular convex portion 32 of the inner lid 2 contacts the lower surface 40 a of the top wall 40 of the outer lid 4, The plurality of engagement pieces 36, 36,... Are configured to contact the inner peripheral wall 42a of the outer lid 4 in a state where the engagement pieces 36, 36,.

  Then, as shown in FIG. 5, the inner lid 2 is placed on the inner side of the outer lid 4 so that the inner circumferential side annular convex portion 32 of the inner lid 2 contacts the lower surface 40 a of the top wall 40 of the outer lid 4. When attached, the plurality of engagement pieces 36, 36,... Of the inner lid 2 get over the engagement projection 44 and abut against the inner peripheral wall 42a of the outer lid 4 in a state of being elastically deformed. As a result, the outer lid 4 and the inner lid 2 are engaged, and the inner lid 2 is held in a state of being attached to the outer lid 4.

  In this embodiment, the plurality of engagement pieces 36, 36,... Abut on the inner peripheral wall 42a of the outer wall 4 in an elastically deformed state, but the plurality of engagement pieces 36, 36,. As long as it is configured to contact the inner peripheral wall 42a, it does not necessarily have to contact the inner peripheral wall 42a in an elastically deformed state. That is, the length r1 from the center line CL4 of the outer lid 4 to the base end of the engaging convex portion 44 shown in FIG. When mounted inside the outer lid 4, the length may be substantially the same as the length r <b> 4 from the center line CL <b> 2 of the inner lid 2 to the tip of the engagement piece 36.

  However, as will be described later, even when the inner lid and the outer lid are engaged with each other in a state of misalignment, the outer lid 4 to which the inner lid 2 is attached is fitted into the mouth portion 52 of the container 5. The inner lid 4 and the outer lid 4 after the inner lid 2 is attached to the outer lid 4 in order to more effectively exert the alignment action that the inner lid 4 is automatically centered. In order to make the misalignment less likely to occur even when an impact is applied from the outside, the plurality of engagement pieces 36, 36,... Are configured to abut against the inner peripheral wall 42a of the outer wall 4 in an elastically deformed state. It is desirable that

  Further, as shown in FIG. 6, the inner lid 2 is mounted on the inner side of the outer lid 4 so that the inner circumferential side annular convex portion 32 of the inner lid 2 contacts the lower surface 40 a of the top wall 40 of the outer lid 4. Further, when the outer lid 4 to which the inner lid 2 is attached is fitted into the mouth portion 52 of the container 5, that is, the outer lid 4 in the state shown in FIG. 5 is fitted into the mouth portion 52 of the container 5. When this occurs, the tip of the mouth portion 52 of the container 5 is pressed against the lower surface 30a of the annular flange 30 of the inner lid 2 and is elastically deformed so that the annular flange 30 is curved upward. The part 34 contacts the inner peripheral wall 42 a of the outer lid 4.

  Therefore, in a state where the outer lid 4 to which the inner lid 2 is attached is fitted into the mouth portion 52 of the container 5, the inner lid 2 is located at the two locations of the inner circumferential annular projection 32 and the outer circumferential annular projection 34. The atmosphere is shielded from the atmosphere outside the container, so that the container 5 can be kept airtight. 2 and 3, the atmosphere in the container 5 and the desiccant 8 are brought into contact with each other through the vent hole 29 penetrating the bottom wall 28 of the inner lid 2, so that the desiccant 8 is brought into contact with the container 5. Moisture contained in the atmosphere can be absorbed to prevent moisture.

  In the present embodiment, since the inside of the container 5 is configured to be kept airtight, the annular flange 30 includes an inner circumferential side annular convex portion 32 protruding upward from the inner circumferential side position, and an outer circumferential side position. Although the outer peripheral side annular convex part 34 which protrudes upward is formed, the lid | cover 1 of the container of this invention is not limited to this.

  That is, the lid 1 of the container of the present invention only needs to be configured to hold the inside of the container 5 in an airtight manner. For example, the upper surface of the annular flange 30 and the lower surface 40a of the top wall 40 are in contact with each other. For example, an annular protrusion may be formed on the lower surface 40a of the top wall 40 so that the annular protrusion and the upper surface of the annular flange 30 come into contact with each other. Thus, the container 5 may be configured to be kept airtight. Further, for example, in order to improve the hermeticity of the container 5, a sheet-like packing is disposed on the lower surface 40a of the top wall 40 of the outer lid 4, and the lower surface 40a of the top wall 40, the upper surface of the annular flange 30, You may comprise so that it may pinch | interpose with the inner peripheral side annular convex part 32 and the outer peripheral side annular convex part 34. FIG.

  Further, as shown in FIG. 2 and FIG. 3, the bottom wall 28 is formed with a weakened portion 31 on the outer peripheral portion and a knob 33 at the center, and pulls the knob 33 downward. Thus, the entire bottom wall 28 can be broken along the weakened portion 31. Therefore, when used, the desiccant 8 is separated and discarded, so that the desiccant 8 can be easily taken out from the inner lid 2 simply by pulling the knob 33.

  The inner lid 2 may be formed by synthetic resin molding from the viewpoint of airtightness of the container 5, elasticity of the annular flange 30, and ease of tearing of the weakened portion 31. (Low density polyethylene), PE-LLD (linear low density polyethylene), PE-MD (medium density polyethylene) and other olefin-based materials can be used alone, or PE-HD for any of these materials (High density polyethylene), EVA (ethylene-vinyl alcohol copolymer resin), or a blend of elastomers can be used.

  Also, as the material of the outer lid 4 and the container 5, various synthetic resin molding materials can be used as in the conventional case. However, when the medicine is stored in the container 5, the plastic bottle for solid lumber is used. In accordance with the standardization request (“Standardization of plastic bottles for solid lumber”, Pharmaceutical Packaging Materials Standardization Committee Satoshi Shinoda PHARM TECH JAPAN Vol.17 No.7 2001 p27-39), the outer lid 4 and the container 5 are made of PE-HD (high density Polyethylene), and the inner lid 2 is preferably formed mainly of PE-LD (low density polyethylene).

  Moreover, the weakening part 31 should just be weakened to such an extent that it can be shredded, and is not specifically limited. The weakened portion 51 of the present embodiment is formed by forming a concave groove having a substantially V-shaped cross section on the lower surface side of the bottom wall 28.

  Next, the operation of the engagement piece 36 of the present invention will be described in comparison with the conventional engagement piece 136 with reference to FIGS. 7, 8, and 9.

FIG. 7 is a diagram illustrating a state in which the engagement piece is elastically deformed when the inner lid is attached to the outer lid.
FIG. 7A shows a state in which the engagement piece 136 of the conventional container lid 100 is elastically deformed and the acting force at that time, and FIG. 7B shows the engagement piece 36 of the container lid 1 of the present invention. The elastically deformed state and the acting force at that time will be described respectively. FIG. 8 is a cross-sectional view showing a state where the lid of the container of the present invention is misaligned. FIG. 9 is a view for explaining a state in which the engagement piece is elastically deformed when the inner lid is pulled out with the inner lid attached to the outer lid. FIG. 9A is a lid of a conventional container. FIG. 9B shows a state in which the 100 engagement pieces 136 are elastically deformed, and FIG. 9B shows a state in which the engagement pieces 36 of the lid 1 of the container of the present invention are elastically deformed.

  In the conventional container lid 100, as shown in FIG. 7A, when the inner lid 102 is attached to the outer lid 104 by applying an upward pushing force P <b> 1 ′ to the inner lid 102, the engagement piece 136. Is pressed by the inner peripheral wall 142a and is elastically deformed so as to rotate downward by an angle α ′ with the base end of the engagement piece 136 as a center from the substantially horizontally projected state indicated by the dotted line in the figure. Then, an elastic restoring force F1 ′ that tries to return to the original substantially horizontal state is generated in the engagement piece 136 in the direction of the arrow F1 ′ in the figure, and this reaction force is generated from the inner peripheral wall 142a as a reaction force R1 ′. Acts on the engagement piece 136. When the vertical component of the reaction force R1 ′ is Rv1 ′ and the horizontal component is Rh1 ′, the pushing force P1 ′ required when the inner lid 102 is attached to the outer lid 104 is the engagement piece 136 and the inner peripheral wall 142a. If the frictional resistance is ignored, it is equal to the vertical component Rv1 ′ of the reaction force R1 ′.

  On the other hand, in the lid 1 of the container of the present invention, as shown in FIG. 7B, when the inner lid 2 is attached to the outer lid 4 by applying an upward pushing force P1 to the inner lid 2. From the state in which the engaging piece 36 is pressed against the inner peripheral wall 42a and protrudes obliquely downward as indicated by the dotted line in the figure, the engaging piece 36 is elastic so as to rotate downward by an angle α around the base end of the engaging piece 36. Deform. Then, an elastic restoring force F1 that tries to return to the original substantially horizontal state is generated in the engagement piece 36 in the direction of the arrow F1 in the figure, and the reaction force R1 is engaged from the inner peripheral wall 42a as this reaction force. Acts on the piece 36. When the vertical component of the reaction force R1 is Rv1 and the horizontal component is Rh1, the pushing force P1 required when the inner lid 2 is attached to the outer lid 4 is the frictional resistance between the engagement piece 36 and the inner peripheral wall 42a. If ignored, it is equal to the vertical component Rv1 of the reaction force R1.

  Here, since the rotation angle α of the engagement piece 36 of the present invention is smaller than the rotation angle α ′ of the conventional engagement piece 136 and the elastic restoring force F1 is also smaller than F1 ′, the reaction force R1 is greater than R1 ′. Is also small. Furthermore, since the engagement piece 36 of the present invention is elastically deformed further downward from the state of projecting obliquely downward, the reaction force R1 is closer to the horizontal than the reaction force R1 ′. Act on. That is, the ratio of the vertical component Rv1 to the reaction force R1 is smaller than the vertical component Rv1 ′ to the reaction force R1 ′.

  Therefore, in the container lid 1 of the present invention, the inner lid 2 can be attached to the inner side of the outer lid 4 with a smaller pushing force P1 than in the conventional container lid 100, so that the mounting workability is excellent.

  Further, in the container lid 1 of the present invention, even if the inner lid 2 and the outer lid 4 are engaged with each other in a misaligned state, the outer lid 4 to which the inner lid 2 is attached is attached to the mouth portion 52 of the container 5. By fitting, the inner lid 2 and the outer lid 4 can be automatically aligned.

That is, as shown in FIG. 8, in the state where the inner lid 2 and the outer lid 4 are engaged in a state of being misaligned, as shown in FIG. The front end of the mouth portion 52 of the container 5 is pressed against the lower surface 30a of the annular flange 30 of the inner lid 2, and is elastically deformed so that the annular flange 30 is curved upward, whereby a plurality of engagement pieces 36, 36, Are pressed against the inner peripheral wall 42a. At this time, if the plurality of engagement pieces 36, 36,... Are elastically deformed unevenly, the engagement pieces 36b that are greatly elastically deformed are restored to a state of projecting obliquely downward. A horizontal force acts toward the piece 36a. Then, since the engaging piece 36a protrudes obliquely downward, it is pressed against the inner peripheral wall 42a and elastically deforms downward again, whereby the inner lid 2 is aligned.

  Thus, in the lid 1 of the container of the present invention, even if the inner lid 2 and the outer lid 4 are engaged in a state of misalignment, the mouth portion 52 of the container 5 is fitted, Since the inner lid 2 and the outer lid 4 are automatically aligned, high airtightness can be stably provided.

  Furthermore, in the container lid 1 of the present invention, even when an impact is applied to the inner lid 2 and the outer lid 4 from the outside after the inner lid is attached to the outer lid, the center is not easily displaced, and thus the airtightness is lowered. do not do.

  That is, in the conventional container lid 100, when an external impact is applied to the inner lid 102 and the outer lid 104 after the inner lid 102 is attached to the outer lid 104, as shown in FIG. 136a may be restored to a substantially horizontal state, causing misalignment, and airtightness may be reduced.

  On the other hand, in the container lid 1 of the present invention, after the inner lid 2 is attached to the outer lid 4, an impact is applied to the inner lid 2 and the outer lid 4 from the outside, and the inner lid 2 and the outer lid are instantaneously applied. 4, even if the engagement piece 36a is restored to the original obliquely projecting state as shown in FIG. 8, the engagement piece 36b that is greatly elastically deformed at the next moment is restored. A horizontal force acts from the side toward the engagement piece 36a. Then, since the engaging piece 36a protrudes obliquely downward, it is pressed against the inner peripheral wall 42a and elastically deforms downward again, thereby eliminating the misalignment between the inner lid 2 and the outer lid 4. To do.

  As described above, in the container lid 1 of the present invention, even when an impact is applied to the inner lid 2 and the outer lid 4 from the outside after the inner lid 2 is attached to the outer lid 4, the engaging piece 36 is inclined downward. Misalignment is unlikely to occur. Therefore, the airtightness is not lowered as in the prior art, and it is possible to stably provide high airtightness.

  Further, in the conventional container lid 100, as shown in FIG. 9A, when the downward pulling force P2 ′ is applied to the inner lid 102, the engaging piece 136 is pressed against the inner peripheral wall 142a, From the state of projecting substantially horizontally as indicated by the dotted line in the figure, it is elastically deformed so as to rotate upward by an angle β ′ around the base end of the engagement piece 136. Then, an elastic restoring force F2 ′ that tries to return to the original substantially horizontal state is generated in the engagement piece 136 in the direction of the arrow F2 ′ in the figure, and this reaction force is generated from the inner peripheral wall 142a as a reaction force R2 ′. Acts on the engagement piece 136. When the vertical component of the reaction force R2 ′ is Rv2 ′ and the horizontal component is Rh2 ′, the pulling force P2 ′ required to pull the inner lid 102 out of the outer lid 104 is the friction between the engagement piece 136 and the inner peripheral wall 142a. If the resistance is ignored, it is equal to the vertical component Rv2 ′ of the reaction force R2 ′.

  On the other hand, in the lid 1 of the container according to the present invention, as shown in FIG. 9B, when the downward pulling force P2 is applied to the inner lid 2, the engagement piece 36 is pressed against the inner peripheral wall 42a. Then, it is elastically deformed so as to rotate upward by an angle β around the base end of the engagement piece 36 from the state of projecting obliquely downward as indicated by the dotted line in the figure. Then, an elastic restoring force F2 that tries to return to the original substantially horizontal state is generated in the engagement piece 36 in the direction of the arrow F2 in the figure, and the reaction force R2 is engaged from the inner peripheral wall 42a as this reaction force. Acts on the piece 36. When the vertical component of the reaction force R2 is Rv2 and the horizontal component is Rh2, the pulling force P2 required to pull the inner lid 2 out of the outer lid 4 is neglected by the frictional resistance between the engagement piece 36 and the inner peripheral wall 42a. For example, it is equal to the vertical component Rv2 of the reaction force R2.

Here, since the rotation angle β of the engagement piece 36 of the present invention is larger than the rotation angle β ′ of the conventional engagement piece 136 and the elastic restoring force F2 is also larger than F2 ′, the reaction force R2 is greater than R2 ′. Is also big. Further, since the engagement piece 36 of the present invention is elastically deformed obliquely upward from a state protruding obliquely downward beyond a horizontal state, the reaction force R2 is compared with the reaction force R2 ′. Acts in a more vertical direction. That is, the proportion of the vertical component Rv2 in the reaction force R2 is larger than the vertical component Rv2 ′ in the reaction force R2 ′.

  Therefore, the container lid 1 of the present invention requires a larger pulling force P2 when the inner lid 2 is pulled out of the outer lid 4 than the conventional container lid 100. For example, the bottom wall 28 of the inner lid 2 is required. The inner lid 2 is not detached when the inner lid 2 is torn off, and the inner lid 2 and the outer lid 4 can be reliably engaged.

The angle formed between the annular flange 30 and the engagement piece 36 is closer to 90 degrees, that is, the inner lid 2 can be attached to the inner side of the outer lid 4 with a smaller pushing force. However, the engagement piece 36 needs to be long and formed downward. Therefore, the angle formed by the annular flange 30 and the engagement piece 36 is within a range of 30 degrees or more and 60 degrees or less so that the engagement piece 36 does not become too long, and the engagement piece is not broken or folded. Preferably, it is formed at 45 degrees in this embodiment.
<Second Embodiment>
10, FIG. 11 and FIG. 12 are views showing the lid 1 of the container according to the second embodiment of the present invention. FIG. 10 is a plan view of the inner lid of the container lid according to the second embodiment of the present invention, and FIG. 11 is a partially enlarged cross-sectional view taken along the line AA of FIG. 10, with the inner lid being attached to the outer lid. FIG. 12 is a partially enlarged cross-sectional view taken along the line AA in FIG. 10 and shows a state after the inner lid is attached to the outer lid. In addition, the same code | symbol is attached | subjected to the member same as the member demonstrated previously, and the description is abbreviate | omitted.

  In the container lid 1 of the second embodiment, as shown in FIG. 10, a plurality of guide pieces 37, 37,... Are formed at the outer peripheral side position of the annular flange 30 of the inner lid 2. The plurality of guide pieces 37, 37,... Are formed in the middle of the plurality of adjacent engagement pieces 36, 36,...

  Further, as shown in FIG. 11, the guide piece 37 protrudes substantially horizontally from the outer peripheral side position of the annular flange 30, and it is easy to get over the engaging convex portion 44 on the upper surface side of the guide piece 37. As shown, a curved taper is provided. Further, the guide piece 37 is formed to be thicker than the engagement piece 36, and in this embodiment, the thickness of the base end portion is formed substantially the same as the thickness of the annular flange 30. The plurality of guide pieces 37, 37,... Are all formed in the same shape.

  Further, as shown in FIG. 11, the plurality of guide pieces 37, 37... Are aligned with the centers of the inner lid 2 and the outer lid 4, and when the inner lid 2 is mounted inside the outer lid 4. The distance r5 from the center line CL2 of the inner lid 2 to the distal end of the guide piece 37 is configured to be substantially equal to the length r1 from the center line CL4 of the outer lid 4 to the base end of the engaging convex portion 44. Has been. That is, when the inner lid 2 is mounted on the inner side of the outer lid 4 so that the inner peripheral annular convex portion 32 of the inner lid 2 contacts the lower surface 40a of the top wall 40 of the outer lid 4, a plurality of guides are provided. The pieces 37, 37,... Are configured to contact the inner peripheral wall 42 a of the outer lid 2 in a state where the pieces 37, 37,.

  Then, as shown in FIG. 12, the inner lid 2 is placed on the inner side of the outer lid 4 so that the inner circumferential side annular convex portion 32 of the inner lid 2 contacts the lower surface 40 a of the top wall 40 of the outer lid 4. When mounted, the plurality of engagement pieces 36, 36,... And the plurality of guide pieces 37, 37,... Over the engagement projection 44 projecting from the inner peripheral wall 42a of the outer lid 4, In a state of projecting horizontally, it abuts on the inner peripheral wall 42 a of the outer lid 4.

As described above, when the inner lid 2 is mounted on the inner side of the outer lid 4, the plurality of guide pieces 37, 37,... Are in contact with the inner peripheral wall 42 a of the outer wall 4 with the original substantially horizontally protruding state. Therefore, it does not elastically deform even when a horizontal force is applied. Further, since it is formed thicker than the engagement piece 36, it is difficult to elastically deform even against an oblique force.

  Therefore, the lid 1 of the container in which such a plurality of guide pieces 37, 37,... Is subjected to an impact on the inner lid 2 and the outer lid 4 from the outside after the inner lid 2 is attached to the outer lid 4. Even if it is added, the inner lid 2 is not displaced in the left-right direction, so that the misalignment is less likely to occur. Further, when the inner lid 2 is attached to the inner side of the outer lid 4, the guide piece 37 serves as a guide and prevents the inner lid 2 from being displaced in the left-right direction. .

  Further, even if a force to pull out the inner lid 2 from the outer lid 4 is applied to the inner lid 2 after the inner lid 2 is mounted on the outer lid 4, the plurality of engagement pieces 36, 36,. Since the guide pieces 37, 37,... Also engage with the engaging convex portion 44 and resist the pulling force, the inner lid 2 becomes more difficult to come off from the outer lid 4, and the inner lid 2 and the outer lid 4 are securely connected. It becomes possible to engage.

The number of the plurality of guide pieces 37, 37,... Only needs to be at least a plurality, and can be set to an appropriate number depending on the shape of the container 5 and the lid 1. Moreover, although the arrangement | positioning space | interval of several guide pieces 37, 37, ... is not specifically limited, When attaching the inner cover 2 to the inner side of the outer cover 4, it effectively prevents that the inner cover 2 shifts in the left-right direction. It is preferable that they are arranged at substantially equal intervals so that they can be made.
<Third Embodiment>

Here, FIG. 13 is a plan view of the packing of the container lid according to the third embodiment of the present invention, and FIG. 14 is a partially omitted sectional view taken along line AA of FIG. In addition, the same code | symbol is attached | subjected to the member same as the member demonstrated previously, and the description is abbreviate | omitted.

  In the lid 1 of the container according to the third embodiment, as shown in FIG. 14, a packing 7 is mounted inside the outer lid 4. As shown in FIG. 13, the packing 7 is formed in a substantially circular shape in plan view and has a flat plate shape. A plurality of engaging pieces 76, 76,... And a plurality of guide pieces 77, 77,... Are formed on the outer periphery of the packing 7, and in this embodiment, eight are formed at substantially equal intervals. Has been.

  The plurality of engaging pieces 76, 76,... Are the same as the engaging pieces 36, 36,... Of the first and second embodiments described above, before the packing 7 is mounted inside the outer lid 4. In this state, the packing 7 protrudes obliquely downward from the outer peripheral side position toward the radially outer side. In addition, the shape of the engagement piece 76 is formed so that the upper surface side is steeply inclined so as to be easily elastically deformed downward, and gradually becomes thinner toward the distal end side. The thickness of the end is about ½ of the thickness of the packing 7. The plurality of engaging pieces 76, 76,... Are all formed in the same shape.

The plurality of guide pieces 77, 77,... Project substantially horizontally from the outer peripheral side position of the packing 7 in the same manner as the plurality of guide pieces 37, 37,. When the packing 7 is mounted on the inner side of the outer lid 4, the packing 7 is configured to come into contact with the inner peripheral wall 42 a of the outer wall 4 with the original substantially horizontally protruding state. In addition, a curved taper is provided on the upper surface side of the guide piece 77 so as to easily get over the engagement convex portion 44. The guide piece 77 is formed to be thicker than the engagement piece 76, and in this embodiment, the thickness of the base end portion thereof is substantially the same as the thickness of the packing 7.

  In the container lid 1 of the third embodiment of the present invention configured as described above, the engagement piece 76 formed at the outer peripheral side position of the packing 7 protrudes obliquely downward toward the radially outer side. Therefore, like the first and second embodiments described above, the packing 7 can be attached to the inside of the outer lid 4 with a small pushing force, and the attached packing 7 is difficult to come off. Further, even when the packing 7 and the outer lid 4 are engaged in a state where misalignment occurs, as in the first and second embodiments described above, the outer lid on which the packing 7 is mounted. The packing 7 is automatically aligned by fitting 4 into the opening 52 of the container 5.

  Further, since a plurality of guide pieces 77, 77,... Are formed, even if an impact is applied to the packing 7 and the outer lid 4 from the outside, the packing 7 is not damaged. Since it does not shift in the left-right direction, misalignment is less likely to occur.

  Further, even if a force for pulling out the packing 7 from the outer lid 4 after the packing 7 is mounted on the outer lid 4, a plurality of guide pieces 77, 77 are provided together with a plurality of engaging pieces 76, 76,. ,... Engages with the engaging projection 44 and resists pulling force, so that the packing 7 is less likely to come off from the outer lid 4, and the packing 7 and the outer lid 4 can be reliably engaged. .

  Further, since the inner circumferential side annular convex portion 72 and the outer circumferential side annular convex portion 74 are provided so as to protrude from the packing 7, the packing 7 is mounted in the same manner as in the first and second embodiments described above. When the outer lid 4 is fitted in the mouth portion 52 of the container 5, the atmosphere inside the container is blocked from the atmosphere outside the container at the two locations of the inner peripheral side annular convex part 72 and the outer peripheral side annular convex part 74. Therefore, the container 5 can be stably and airtightly maintained over a long period of time.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made without departing from the object of the present invention.

  For example, in the above embodiment, the desiccant 8 is accommodated in the inner lid 2, but the contents accommodated in the inner lid 2 are not limited to the desiccant, and separation and disposal are required. Even other items can be used preferably.

  Further, for example, in the above embodiment, the container 5 contains the medicine. However, the container contained in the container 5 is not limited to the medicine, and high airtightness and high moisture resistance are required. It is possible to use them even if they are contained.
