Description

  The present invention relates to a container with a cap for preventing accidental ingestion that prevents an accident or the like in which a child accidentally opens a cap and drinks contents such as a chemical solution contained in the container.

  Conventionally, many containers with caps that consist of containers that contain various liquids, tablets, etc. and caps that are screwed to the mouths of the containers have circulated. Since it is only screwed, even a child can easily open the lid. Therefore, even when a chemical solution or the like harmful to the human body is stored in the container, there is a possibility that an accident or the like may occur in which the child accidentally opens the lid and drinks the chemical solution or the like in the container.

  In order to prevent such an accident, for example, a container safety cap as shown in FIG. 11 has been proposed. The safety cap includes an outer cap 41 and an inner cap 42 accommodated in the outer cap 41 so as to be rotatable and movable up and down, and six are provided on the outer peripheral edge of the upper wall 41a of the outer cap 41. And four fixed claws 45 constituting one of the ratchet mechanisms 44 are projected on the inner peripheral portion, and six keys 46 are formed on the upper end surface of the cylindrical body 42a of the inner cap 42. And four stop claws 47 constituting the other side of the ratchet mechanism 44 are provided on the middle wall 42b. Each of the restraining claws 47 has an elastic force that is bent deeply when a downward pressing force is applied and returns to the original state when the pressing force is released.

And when closing a container mouth with said safety cap, the outer cap 41 is rotated clockwise as usual. At this time, both the inner and outer caps 41 and 42 are integrated by meshing between the fixing claw 45 of the ratchet mechanism 44 and the key 46, and the inner cap 42 can be screwed to the container port. On the other hand, when the lid is opened, the outer cap 41 is merely rotated idly by the ratchet mechanism 44 even if the outer cap 41 is rotated in the counterclockwise direction. Are engaged, and both the inner and outer caps 41 and 42 are integrated by this engagement, and then the outer cap 41 is rotated counterclockwise (see, for example, Patent Document 1). In the figure, 48 is an internal thread that is screwed into an external thread (not shown) of the container opening, and 49 is a packing.
Japanese Patent Laid-Open No. 10-152155

  However, in the above-described safety cap, the outer cap 41 has six protrusions 43 and four fixing claws 45 constituting one of the ratchet mechanisms 44, and the inner cap 42 has six keys 46 and Since the four stop pawls 47 constituting the other side of the ratchet mechanism 44 are provided in a protruding manner, the structure is complicated and the manufacturing cost is increased. Moreover, since the ratchet mechanism 44 is complicated as described above, if a pressing force is applied to the fixed claw 45 and the stop claw 47 constituting the ratchet mechanism 44 during the opening operation, the fixed claw 45 and the stop claw 47 (particularly, The restraining claw 47) bent deeply by the pressing force is easily damaged or broken. Moreover, since the protrusion 43, the key 46, and the ratchet mechanism 44 are provided between the upper wall 41a of the outer cap 41 and the inner wall 42b of the inner cap 42, the height of the safety cap increases. As a result, the entire container becomes larger.

  The present invention has been made in view of such circumstances, and it is difficult for a child to understand the method of opening the lid, and the cap is simple in structure, hardly damaged or broken, and can be downsized. The purpose is to provide attached containers.

  In order to achieve the above object, a container with a cap according to the present invention includes a container, a cap that is screwed into the mouth of the container, and an annular body that is provided so as to be movable up and down while being externally fitted to the cap. A first threaded portion is formed on the outer peripheral surface of the mouth portion, a first engaging portion is formed on the lower side, and the first threaded portion is screwed onto the inner peripheral surface of the cap. A second engagement portion is formed on the outer peripheral surface, and is engaged with the second engagement portion on the inner peripheral surface of the cap on the inner peripheral surface of the annular body. A third engagement portion that prevents relative rotation in the circumferential direction of the cap is formed, and the lower side engages with the first engagement portion on the outer peripheral surface of the mouth portion in the closed state, and this engagement To prevent relative rotation in the circumferential direction of the mouth portion and raise the annular body to disengage the first engagement portion. A configuration referred to as a fourth engagement portion that allows turns with the cap in the rotation of the annular body is formed.

  In other words, the cap-equipped container of the present invention is in a state where the cap is screwed to the mouth portion of the container in the closed state, and the cap is externally fitted to the first engaging portion on the outer peripheral surface of the mouth portion. A fourth engaging portion on the inner peripheral surface of the annular body provided so as to be movable up and down is engaged in the circumferential direction of the mouth portion so as not to be relatively rotatable. When shifting from the closed state to the open state, the annular body is raised to disengage the engagement portions, and the annular body is rotated in the opening direction in this state. Do. As a result, the cap rotates with the rotation of the annular body, and since the cap is screwed into the mouth portion, the cap rises along the mouth portion and is removed from the mouth portion. On the other hand, in the case of closing the lid, the procedure reverse to the opening operation is performed.

  As described above, in the container with a cap of the present invention, when the lid is opened, the annular body must be raised and then rotated in a predetermined direction, which makes it difficult for a child to understand how to open the lid. In the above-described structure of the present invention, the cap and the annular body are provided with the second engaging portion such as the knurling and the third engaging portion in addition to the threaded portion, and the outer periphery of the mouth portion is formed on the inner peripheral surface of the annular body. Only the fourth engagement part that makes the relative rotation in the circumferential direction of the mouth part impossible by the engagement with the first engagement part of the surface is formed, the structure is simple, and the manufacturing cost is low. In addition, the lid opening operation can be performed simply by raising the annular body along the cap and rotating it in the circumferential direction of the cap, so that excessive external force does not act on the annular body or the cap, resulting in damage or breakage. There is no. In addition, since the annular body is merely fitted on the cap, it is not necessary to increase the height of the cap, and the entire container can be reduced in size.

  In addition, a plurality of concave grooves are formed in the outer peripheral surface of the cap as second engaging portions in the vertical direction, and the circumferential direction of the cap is provided in the concave grooves as third engaging portions on the inner peripheral surface of the annular body. When a plurality of ridges that are engaged with each other so as not to rotate relative to each other and are slidably engaged with each of the concave grooves are formed vertically, a plurality of ridges are formed on the outer peripheral surface of the cap. The groove is formed in a vertical direction, and a plurality of ridges engaging with the groove are formed in the vertical direction on the inner peripheral surface of the ring body. It can be attached so as not to be relatively rotatable in the circumferential direction and to be movable up and down along the cap.

  Next, the best mode for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

  1 and 2 show an embodiment of a container with a cap according to the present invention. In these drawings, reference numeral 1 denotes a synthetic resin container, and a barrel portion 2 for storing contents (not shown) such as a chemical solution therein, and a diameter of the barrel portion 2 is reduced upward from an upper end opening of the barrel portion 2. And a mouth portion 4 extending in a substantially cylindrical shape upward from the upper end opening of the shoulder portion 3.

  As shown in FIG. 3, the first screw portion 5 is engraved on the outer peripheral surface of the mouth portion 4, and a part of the lower end portion (right side portion in this embodiment) is described later. A convex portion (first engaging portion) 6 that engages with a concave portion 25 (see FIG. 7) of the outer ring 21 that slidably moves in the vertical direction and engages with the circumferential direction of the outer ring 21 in a relatively non-rotatable manner. (See FIG. 4).

  Reference numeral 11 denotes a synthetic resin cap (see FIG. 1), which is formed in a substantially cylindrical shape. The cap 11 has a second threaded portion 12 (see FIG. 5) that is screwed into the first threaded portion 5 on the inner peripheral surface thereof. Further, the cap 11 has an upper and lower direction in each concave groove 23 (see FIG. 7) of the outer ring 21 on both opposite sides (in this embodiment, both left and right sides) of the outer peripheral surface. Three ridges (second engagement portions) 13 (see FIG. 6) that are slidably engaged and engage with each other in the circumferential direction of the outer ring 21 are formed in a straight line. . That is, a knurled structure is formed by the ridges 13 and the concave grooves 23, and frictional resistance is generated when the ridges 13 and the concave grooves 23 slide in the vertical direction due to their meshing. It cannot be moved up and down easily (with a small force). Further, an annular stopper 14 is provided at the lower end portion of the outer peripheral surface of the cap 11 so as to support the upper ridge 22 of the outer ring 21 in a closed state in a closed state (see FIG. 2). . Further, a recess 11b is formed on the lower surface of the ceiling wall 11a of the cap 11, and an elastic sealing material 15 made of silicon rubber (with rubber hardness) seals the upper surface opening of the mouth portion 4 in the recess 11b. Shore A hardness is in the range of 40 to 90 degrees) and is fixed and accommodated.

  In FIG. 1, 21 is an outer ring (annular body) made of synthetic resin fixed to the cap 11 in an outer fitting shape, and as shown in FIGS. The ridges 22 project in an annular shape, and slide on the ridges 13 in the vertical direction on the upper part of the ridges 22 corresponding to the ridges 13 (in this embodiment, both the left and right sides). A concave groove (third engagement portion) 23 that is freely engaged and is engaged in the circumferential direction of the cap 11 so as not to be relatively rotatable is formed. Further, a lower ridge 24 is formed in an annular shape at the lower end portion of the inner peripheral surface of the outer ring 21, and a part thereof (a portion corresponding to the convex portion 6 of the mouth portion 4) is attached to the lower ridge 24. A concave portion (fourth engaging portion) 25 is formed to engage with the convex portion 6 of the mouth portion 4 so as to be slidable in the vertical direction while penetrating vertically.

  In the above configuration, when the cap 11 is closed on the mouth portion 4 of the container 1, both the screw portions 5 and 12 are screwed, and the cap 6 is fitted on the convex portion 6 of the mouth portion 4 of the container 1. 11 is engaged with the recess 25 of the outer ring 21 (see FIG. 2), which is fixed to the outer ring 21 (not rotatable relative to the circumferential direction and movable up and down). The relative rotation in the circumferential direction is impossible.

  When the cap 11 is opened from this closed state, as shown in FIG. 10 from the state of FIG. 2, it resists the frictional resistance caused by the engagement between the ridges 13 and the grooves 23 constituting the knurled structure. Then, the outer ring 21 is raised, the engagement between the convex portion 6 of the mouth portion 4 and the concave portion 25 of the outer ring 21 is released, and the outer ring 21 is rotated counterclockwise (opening direction) in that state. I do. As a result, the cap 11 is rotated along with the rotation of the outer ring 21, and the cap 11 is screwed to the mouth portion 4, so that the cap 11 rises along the mouth portion 4 and moves from the mouth portion 4. Removed.

  On the other hand, when the cap 11 is closed, first, the cap 11 is inserted into the mouth 4 of the container 1 with the outer ring 21 raised, and finally the outer ring 21 is moved clockwise. After the cap 11 is screwed into the mouth portion 4 while rotating, the outer ring 21 is lowered to engage the convex portion 6 of the mouth portion 4 with the concave portion 25 of the outer ring 21. Thereby, the outer ring 21 cannot be rotated relative to the mouth portion 4 in the circumferential direction.

  Thus, in the above embodiment, when the lid is opened, the outer ring 21 must be raised and then rotated in a predetermined direction, which makes it difficult for a child to understand how to open the lid. In the structure described above, six ridges 13 are formed on the outer peripheral surface of the cap 11, six concave grooves 23 are formed on the inner peripheral surface of the outer ring 21, and the mouth is formed on the inner peripheral surface of the outer ring 21. Since only the concave portion 25 that is engaged with the convex portion 6 of the portion 4 is formed, the structure is simple and the manufacturing cost is low. Moreover, since the lid opening operation can be performed only by raising the outer ring 21 and rotating it in a predetermined direction, an excessive external force does not act on the outer ring 21 and the cap 11, and they are not damaged or broken. . In addition, since the outer ring 21 is only fixed to the cap 11 in an outer fitting shape, the height of the cap 11 can be kept low, and the overall size of the container 1 can be reduced.

  In the above-described embodiment, three ridges 13 are formed vertically on the left and right sides of the outer peripheral surface of the cap 11, and the left and right sides of the inner peripheral surface of the outer ring 21 are respectively Three concave grooves 23 that engage with the ridges 13 are formed vertically (the knurled structure is formed), but the outer ring 21 is movable up and down with respect to the cap and in the circumferential direction. Any structure may be used as long as it cannot be relatively rotated.

  Moreover, in the said embodiment, although the convex part 6 is protrudingly provided in the right side part of the outer peripheral surface of the said mouth part 4, and the recessed part 25 is formed in the right side part of the inner peripheral surface of the outer ring 21, the said mouth part A first engaging portion other than the convex portion 6 is formed on the outer peripheral surface of the outer ring 21, and when the outer ring 21 is lowered on the inner peripheral surface of the outer ring 21, the mouth portion 4 is formed on the first engaging portion. A fourth engaging portion other than the concave portion 25 is formed which can be engaged in the circumferential direction so as not to rotate relative to each other and can be disengaged from the first engaging portion by raising the outer ring 21. May be.

  Moreover, in the said embodiment, although the elastic material which comprises the elastic sealing material 15 is a silicone rubber, it is not limited to this, Various elastic materials can be used. However, a low-hardness elastic material that can be easily pushed down by a child or the like (with a small force) is not preferable.
