Description

  The present invention relates to a container with a cap for preventing accidental ingestion so as to prevent an accident or the like in which a child accidentally opens a cap and drinks a liquid medicine or the like 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. In addition to the protrusion 43 and the key 46 provided between the upper wall 41a of the outer cap 41 and the inner wall 42b of the inner cap 42, the ratchet mechanism 44 is also provided. Since 44 is formed long in the vertical direction, the height of the safety cap is increased, and the entire container is enlarged accordingly.

  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 screwed into the mouth of the container, the mouth and the cap in a state where the upper end opening of the mouth is closed. An inner cap that is screwed to the mouth portion in a closed state, and an outer periphery of the inner cap that is relatively rotatable in the circumferential direction and is vertically movable. And an outer cap that is movably attached. An engaging portion is formed on one of the ceiling wall of the outer cap and the ceiling wall of the inner cap, and the other is detachably engaged with the engaging portion. In this engaged state, an engaged portion is formed in which both caps cannot be rotated relative to each other in the circumferential direction, and a substantially circular through hole is formed in the ceiling wall of the inner cap in plan view. Elasticity of a substantially circular shape in plan view disposed between the inner cap and the inner cap The central upper surface of Lumpur material, generally circular plan view shape of the convex portion projecting on the inner cap through said through-hole is protruded integrally molded, the protrusion is the upper half is a truncated cone And a lower portion thereof is formed into a cylindrical body that is inserted into the through hole of the inner cap, and the ceiling wall of the outer cap on the upper surface of the convex portion has a predetermined gap between the two engaging portions. In this closed state, the outer cap is lowered against the elastic force of the convex portion of the elastic seal material to engage both the engaging portions to rotate the outer cap. The configuration is such that the inner cap is twisted so that it can be opened.

That is, the container with a cap of the present invention includes a container, a cap constituted by an inner cap and an outer cap, and an elastic sealing material having a substantially circular shape in plan view in which convex portions are integrally projected from the upper surface of the container. It has. Further, in the engaged state in which the engaging portion is formed on one of the ceiling wall of the outer cap and the ceiling wall of the inner cap, the engaged portion is formed on the other, and the engaging portions are engaged with each other. Both caps are configured such that they cannot rotate relative to each other in the circumferential direction. In addition, the substantially circular convex portion in plan view formed on the upper surface of the central portion of the elastic seal material has an upper half portion formed in a truncated cone shape, and a lower portion thereof inserted into the through hole of the inner cap. Is formed in a cylindrical body, protrudes through the substantially circular through-hole in a plan view of the ceiling wall of the inner cap, and protrudes on the inner cap in the closed state. Is supported in a non-engaged state in which a predetermined gap is provided between the two engaging portions. In such a closed state, the outer cap is pressed downward, and by this pressing, the outer cap is lowered against the elastic force of the convex portion of the elastic seal material to engage the both engaging portions. When the outer cap is rotated in the opening direction in the engaged state, the inner cap is rotated and rotated in the opening direction, thereby opening the lid.

  As described above, in the container with a cap of the present invention, when opening the lid, the cap must be pressed downward and then rotated in a predetermined direction, which makes it difficult for a child to understand how to open the lid. In addition, since both the engaging portions are formed on the cap and the convex portions are formed on the elastic sealing material, the structure is simple and the manufacturing cost is reduced. In addition, the lid opening operation can be performed simply by rotating the cap after pressing the cap downward and pressing the convex portion of the elastic seal material against its elastic force. Unreasonable external force does not act, and the convex part and cap of the elastic sealing material are not damaged or broken. In addition, since only the engaging portions are formed between the ceiling walls of the inner and outer caps, the height between the ceiling walls can be kept low, and the entire container can be reduced in size.

  In addition, the engaging portion formed on the lower surface of the ceiling wall of the outer cap has a plurality of upper projections protruding downward from the outer peripheral portion of the lower surface of the ceiling wall of the outer cap along the circumferential direction at a predetermined interval. The engaged portion formed on the upper surface of the ceiling wall of the inner cap protrudes upward from the portion corresponding to the gap between the upper convex portions of the outer peripheral surface of the upper surface of the ceiling wall of the inner cap. In the case of the plurality of provided lower convex portions, the engagement portions can be easily engaged and disengaged only by pressing the ceiling wall of the outer cap downward.

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

  FIG. 1 shows an embodiment of a container with a cap according to the present invention. In the figure, 1 is a container made of synthetic resin, and has a barrel portion 2 for storing contents (not shown) such as a chemical solution inside, and a diameter decreasing from the upper end opening of the barrel portion 2 upward. A shoulder portion 3 that extends and a mouth portion 4 that extends upward in a substantially cylindrical shape from the upper end opening of the shoulder portion 3 are provided. As shown in FIG. 2, the first screw portion 5 is intermittently engraved on the outer peripheral surface of the mouth portion 4.

  Reference numeral 11 denotes a cap (see FIG. 1), which has an inner / outer double cap structure including an inner cap 12 and an outer cap 13 (both are made of synthetic resin) formed in a substantially cylindrical shape. As shown in FIG. 3, the inner cap 12 is intermittently engraved with a second screw portion 14 that is screwed into the first screw portion 5 on the inner peripheral surface thereof. Further, as shown in FIGS. 4 and 5, the inner cap 12 is provided with a through-hole 15 through which a convex portion 23 of an elastic sealing material 21 to be described later can be inserted in the central portion of the ceiling wall 12 a. A plurality of (eight in this embodiment) lower ribs (engagement portions) 16 are erected from the upper surface of the outer peripheral edge of the ceiling wall 12a at predetermined intervals along the circumferential direction. Projected. Further, the inner cap 12 has an annular convex portion on the lower outer peripheral surface of the peripheral side wall 12b, which engages with the annular concave groove 19 of the outer cap 13 so as to be rotatable in the circumferential direction and movable up and down. 17 protrudes.

  As shown in FIGS. 6 and 7, the outer cap 13 is detachably attachable to the gaps from the lower surface of the outer peripheral edge of the ceiling wall 13a to a portion corresponding to the gaps between the lower ribs 16. A plurality (eight in this embodiment) of upper ribs (engaged portions) 18 that engage and engage with each other so as not to rotate relative to each other in the circumferential direction are suspended. Further, the outer cap 13 is formed with an annular groove 19 on the lower inner peripheral surface of the peripheral side wall 13b, which engages with the annular convex portion 17 so as to be rotatable in the circumferential direction and movable up and down. (See FIG. 6).

Reference numeral 21 denotes an elastic seal material made of silicon rubber. As shown in FIGS. 8 and 9, the disc portion 22 and a convex portion 23 that is integrally projected from the upper surface of the central portion of the disc portion 22. It has become. The protrusion 23 has its upper half portion that is formed in a truncated cone shape, the lower portion thereof is formed into a circular columnar body to be inserted into the through hole 15 of the inner cap 12.

  In the above configuration, in a state where the cap 11 is closed on the mouth portion 4 of the container 1, the both screw portions 5 and 14 are screwed together. The ceiling wall 13a of the outer cap 13 is supported by the elastic force of the convex portion 23 of the elastic sheet material 21, and the ribs 16 and 18 are not engaged in this state. Further, the lower surface of the annular convex portion 17 of the inner cap 12 is in contact with the lower surface of the annular concave groove 19 of the outer cap 13 (see FIG. 1).

  When the cap 11 is opened from this closed state, first, the ceiling wall 13a of the outer cap 13 is pressed downward, and the outer cap is resisted against the elastic force of the convex portion 23 of the elastic sheet material 21 by this pressing. 13 is pushed down to engage the ribs 16 and 18 (see FIG. 10), and then the outer cap 13 is rotated counterclockwise. As a result, the inner cap 12 rotates and rotates counterclockwise, and the cap 11 rises and is removed from the mouth 4 of the container 1. At this time, the upper surface of the annular convex portion 17 of the inner cap 12 is in contact with the upper surface of the annular concave groove 19 of the outer cap 13. When the pressing of the outer cap 13 is stopped after the opening, the outer cap 13 is pushed up by the elastic force of the convex portion 23 of the elastic sheet material 21, and the engagement of the ribs 16 and 18 is released. In this state, even if the outer cap 13 is rotated clockwise or counterclockwise, it only rotates idly.

On the other hand, in the case of closing the cap 11, first, externally fitted to cap 11 to the mouth 4 of the container 1, one technique, the each rib ceiling wall 13a of the outer cap 13 is pressed against the lower side 16 , 18 are engaged, and the outer cap 13 is rotated in the clockwise direction.

  Thus, in the above embodiment, when the lid is opened, the outer cap 13 must be pressed downward and then rotated in a predetermined direction, which makes it difficult for the child to understand how to open the lid. In addition, since the ribs 16 and 18 are formed on the cap 11 and the convex portions 23 are formed on the elastic sealing material 21, the structure is simple and the manufacturing cost is low. Moreover, the lid opening operation can be performed simply by rotating the outer cap 13 after pressing the outer cap 13 downward and pressing the convex portion 23 of the elastic seal member 21 against its elastic force. Unreasonable external force does not act on the convex portions 23 of the 21 and the ribs 16 and 18 of the cap 11, so that they are not damaged or broken. Moreover, since the ribs 16 and 18 and the upper half of the convex portion 23 are only provided between the ceiling walls 12a and 13a of the inner and outer caps 12 and 13, the width between the ceiling walls 12a and 13a. Can be kept small, and the overall size of the container 1 is reduced.

  In the above embodiment, a plurality of lower ribs 16 project from the ceiling wall 12a of the inner cap 12 to integrally rotate the inner and outer caps 12 and 13 when the lid is opened, and the outer cap 13 A plurality of upper ribs 18 are vertically provided on the ceiling wall 13a, but the present invention is not limited to this, and it has a detachable structure and shape capable of rotating both the inner and outer caps 12 and 13 integrally. Any structure and shape are possible.

  Moreover, in the said embodiment, although the elastic material which comprises the elastic sealing material 21 is a silicon rubber, various elastic materials can be used. However, an elastic material that can be easily pushed down by a child or the like (with a small force) is not preferable. The protruding length of the convex portion 23 of the elastic seal material 21 protruding from the ceiling wall 12a of the inner cap 12 depends on the dimensions of the ribs 16 and 18 and the type of elastic material constituting the elastic seal material 21. Although it sets suitably, it is usually set in the range of 1-5 mm, More preferably, it sets in the range of 2-3 mm.
