Description

  The present invention relates to a container with a cap for preventing tampering in which various kinds of containers such as a cosmetic container, a food container, and a vial can be easily seen whether the cap is opened or not.

  Conventionally, many containers with caps that consist of containers that contain various contents such as cosmetics and foods and caps that are screwed to the mouths of the containers have been on the market. Since the cap is only screwed to the part, the lid can be easily opened. Therefore, there is a risk that the contents are easily falsified.

  In order to prevent such tampering and the like, for example, bottles with caps as shown in FIGS. 19 and 20 have been proposed. The bottle with a cap includes a bottle 41 and a cap 42 that is screwed into the mouth portion 41 a of the bottle 41. The cap 42 has a top plate portion 43, a peripheral wall portion 44 in which a screw portion (not shown) is formed on the inner peripheral surface, and the screw portion is screwed into the screw portion 41b of the mouth portion 41a, and the peripheral wall. An annular band portion 45 disposed at a lower end side of the portion 44 at a predetermined interval and engaged with an annular engagement portion 41c (below the screw portion 41b) of the mouth portion 41a; the peripheral wall portion 44; A connecting portion 46 disposed between the band portion 45 and connecting the peripheral wall portion 44 and one end (in the circumferential direction) of the band portion 45, and the peripheral wall portion formed between the peripheral wall portion 44 and the band portion 45. 44 and the band part 45 are formed between the first bridge part 47 that detachably connects the band part 45 (with the connection part 46 left) and the both ends (circumferential direction) of the band part 45 and separates both the ends. It consists of the 2nd bridge part 48 connected so that it is possible.

When the cap 42 is rotated in the opening direction, the first and second bridge portions 47 and 48 of the cap 42 are cut off during the rotation, and the band portion 45 is connected to the peripheral wall portion 44 via the connecting portion 46. In this state, the bottle 41 is removed from the mouth 41a (see FIG. 20). Further, in the case of using again (that is, closing again after opening), the connecting portion 46 is cut by bending or the like and the band portion 45 is removed from the peripheral wall portion 44, and then the cap 42 is removed from the mouth portion 41a. (See, for example, Patent Document 1).
Japanese Patent Application Laid-Open No. 2005-8202

  However, in the bottle with the cap, when the cap 42 is removed from the mouth portion 41a of the bottle 41 and then used again, the band portion 45 is separated from the peripheral wall portion 44 by cutting the connecting portion 46 by bending or the like. In addition, this operation takes time and may injure fingers during this operation. In addition, when the cap 42 is removed from the mouth portion 41a, an uneven cut-off portion is exposed at the lower end surface of the peripheral wall portion 44 of the cap 42. Therefore, when the cap 42 is screwed to the mouth portion 41a. There is a risk that a finger may touch the cut-off portion and get injured. Moreover, when the cover is opened, it is only necessary to rotate the cap 42 in the opening direction, and even a child can easily open the cover. Therefore, even when a chemical solution or the like harmful to the human body is contained in the bottle 41, there is a risk 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 bottle 41.

  The present invention has been made in view of such circumstances, and when the cap is removed from the mouth portion of the container and then used again, the cap can be attached to the mouth portion as it is, and the attaching operation is being performed. The purpose is to provide a container with a cap that does not injure fingers.

  In order to achieve the above object, a container with a cap according to the present invention comprises a container and a cap screwed onto the mouth of the container, and an annular flexible plate is fixed to the root of the mouth, and the annular A protrusion is formed at a predetermined position on the upper surface of the flexible plate, and a tongue piece is formed at the outer peripheral portion corresponding to the protrusion forming portion. The protrusion of the annular flexible plate is formed at the opening of the cap. An engaging protrusion is formed.When the lid is closed, the protrusions are engaged to prevent the cap from rotating.When the lid is opened, the cap is rotated with the tongue piece pressed downward to engage the protrusions. The configuration is such that it is configured to be removed.

  That is, in the container with a cap of the present invention, in the closed state, the protrusion formed on the upper surface of the annular flexible plate (fixed to the root of the mouth of the container) is screwed to the mouth of the container. ) It is engaged with a protrusion formed in the opening of the cap, and the cap is prevented from rotating by this engagement. When opening from such a closed state, the tongue piece formed on the outer periphery of the annular flexible plate is pressed downward with fingers, and the cap is rotated in the open direction in this state to After disengaging both protrusions, the cap is continuously rotated in the direction of opening the cap, and the cap is removed from the mouth of the container to open the cap.

  As described above, in the container with a cap according to the present invention, when the lid is opened, the engagement between the protrusion formed on the upper surface of the annular flexible plate and the protrusion formed on the opening of the cap must be disengaged. However, when releasing this engagement, a large force is required, and the resistance at that time gives an image of unopened, but once the lid is opened, the above-mentioned engagement is already released, so it is small. The lid can be opened with force. Therefore, when opening the lid, it can be easily determined whether the lid has been opened or not yet opened by distinguishing whether a large force is required or a small force can be used. Moreover, when the lid is opened, it is only necessary to rotate the cap in the direction of opening the lid while pressing the tongue piece portion of the annular flexible plate downward with fingers. When the lid is closed), the protrusions formed in the opening of the cap are not injured when touched by hand, unlike the uneven cut-out part as in the conventional example. There is no risk of injury to fingers. In addition, when opening the lid, the tongue piece of the annular flexible plate must be pressed downward with fingers, making it difficult for the child to understand how to open the lid.

  In the present invention, the cap protrusion and the annular flexible plate protrusion are engaged with each other in the state of being adjacent to the circumferential direction of the cap in the closed state, and the cap is prevented from rotating. The cap is rotated in a pressed state, and the protrusion of the cap is pressed by the upper part of the protrusion of the annular flexible plate lowered by the pressing of the tongue piece, thereby deforming or destroying the protrusion of the annular flexible plate. When the engagement is disengaged, the projection of the annular flexible plate may be elastically deformed when the lid is opened, or it may be plastically deformed or destroyed. The degree is increased.

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

  1 to 3 show an embodiment of a container with a cap according to the present invention. In the figure, reference numeral 1 denotes a synthetic resin container. In this embodiment, a high-grade cosmetic container is used. The container 1 includes a substantially cylindrical body portion 2 for accommodating cosmetics (not shown) therein, and a shoulder portion 3 (the body portion described above) extending in a reduced diameter from the upper end opening of the body portion 2 upward. And a mouth portion 4 (see FIG. 3) extending in a substantially cylindrical shape upward from the central opening of the shoulder portion 3.

  As shown in FIG. 4 to FIG. 6, the first threaded portion 5 (not shown in FIG. 6) is engraved on the outer peripheral surface of the upper small diameter portion 4a. A plurality or one (a pair of left and right in this embodiment) of vertical grooves 6 are formed on the outer peripheral surface of the large-diameter portion 4b straight from the upper end surface downward.

  11 is a substantially ring-shaped synthetic resin flexible ring plate (annular flexible plate) fixed to the lower large-diameter portion 4b of the mouth portion 4 in an outer fitting manner, and is shown in FIGS. As described above, from the inner peripheral surface (that is, the peripheral side surface of the central hole portion 11a), the vertical grooves 6 of the lower large-diameter portion 4b can be detachably attached in the circumferential direction of the mouth portion 4 and vertically. Plural or one (a pair of left and right in this embodiment) projecting pieces 12 that are engaged with each other are projected inward. In addition, along the periphery of the flexible ring plate 11 with a predetermined distance from the periphery of the central hole portion 11a from the upper surface of a predetermined portion (the front portion in this embodiment) of the flexible ring plate 11. A plurality of or one (three in this embodiment) ribs (projections) 13 are provided so as to project from the above-mentioned flexibility corresponding to the locations (rib-forming locations) where the ribs 13 are formed. A substantially semicircular tongue piece 14 projects outward from the outer peripheral surface of the ring plate 11. The central hole portion 11a is formed in a round hole shape through which the mouth portion 4 can be inserted.

  Each of the ribs 13 is formed in a substantially isosceles triangle shape when viewed from the front, and includes a vertical surface 13a extending vertically from the upper surface of the flexible ring plate 11, and an opening direction of the cap from the upper end of the vertical surface 13a ( In this embodiment, it has an inclined surface 13b extending in a downward inclined direction (counterclockwise direction).

  Reference numeral 21 denotes a synthetic resin cap (see FIG. 1) that is screwed into the mouth portion 4. As shown in FIGS. 10 to 12, a disc-shaped ceiling wall 22 and a cylindrical peripheral side wall 23 are provided. It is formed in a cylindrical cylindrical shape. The peripheral side wall 23 has a second threaded portion 24 engraved on the inner peripheral surface thereof, which is engaged with the first threaded portion 5 of the mouth portion 4, and the lower end surface has a predetermined length over the entire circumference. A plurality or one (in this embodiment, twelve) ribs (projections) 25 are provided so as to be detachably engaged with the ribs 13 in a state where the distance is set. Reference numeral 26 denotes a flange projecting from the outer peripheral surface of the lower end of the peripheral side wall 23.

  Each of the ribs 25 is formed in a substantially isosceles triangle when viewed from the front. The vertical surface 25a extends perpendicularly from the lower end surface of the peripheral side wall 23, and the cap closing direction (in this embodiment) extends from the lower end of the vertical surface 25a. In the embodiment, it has an inclined surface 25b extending in an upwardly inclined direction (clockwise direction). In FIGS. 3 and 12, reference numeral 27 denotes a silicone rubber sealing material that covers the mouth 4 in a sealed manner, and is bonded and fixed to the lower surface of the ceiling wall 22. In addition, since the cap 21 which consists of a celestial cylindrical body which has such a 1st thread part 5 and the some rib 25 is usually used well, this may be utilized and this Embodiment You may make it for exclusive use.

  In the above configuration, in the closed state, the three ribs 13 of the flexible ring plate 11 engaged with the lower large-diameter portion 4b of the mouth portion 4 of the container 1 in the circumferential direction so as to prevent rotation. The three ribs 25 of the cap 21 corresponding to the ribs 13 are engaged in the state adjacent to the circumferential direction, and by this engagement, the cap 21 is prevented from rotating in the opening direction ( (See FIGS. 13 and 14).

  When the cap 21 is opened from this closed state, the tongue piece portion 14 of the flexible ring plate 11 is moved downward with the fingers from the state of FIG. 13 (for example, until it abuts against the shoulder portion 3 of the container 1). By pressing, each rib 13 of the flexible ring plate 11 is moved downward (see FIGS. 15 and 16), and the cap 21 is rotated in the opening direction in that state. By this rotational force, the three ribs 25 of the cap 21 press the upper portions of the three ribs 13 of the flexible ring plate 11 in the direction of opening the lid, and these are plastically deformed or broken to release the above engagement. After that, the cap 21 is rotated as it is in the opening direction, and is removed from the mouth portion 4 and opened (see FIGS. 17 and 18).

  When the cap 21 is closed after the lid is opened, the flexible ring plate 11 is lifted and removed from the lower large-diameter portion 4b, and then further lifted along the outer peripheral portion of the mouth portion 4 After removing from the part 4, the cap 21 is screwed onto the mouth part 4.

  When the flexible ring plate 11 and the cap 21 are first set in the mouth portion 4, the flexible ring plate 11 is inserted into the mouth portion 4 and the lower large diameter portion of the mouth portion 4 is inserted. After engaging both the projecting pieces 12 of the flexible ring plate 11 with both the vertical grooves 6 of 4b, the cap 21 is screwed onto the mouth portion 4. In this screwing, at the end of the rotation of the cap 21, the rib 25 of the cap 21 climbs over the upper surface of each rib 13 of the flexible ring plate 11 and is adjacent to each rib 13 of the flexible ring plate 11 in the circumferential direction. Engage in the state.

  Thus, in the above embodiment, when the lid is opened, the engagement between the rib 13 of the flexible ring plate 11 and the rib 25 of the cap 21 must be disengaged. A force is required, and the resistance at that time gives an unopened image, but once the lid is opened, the engagement is already released, so the lid can be opened even with a small force. Therefore, when opening the lid, it can be easily determined whether the lid has been opened or not yet opened by distinguishing whether a large force is required or a small force can be used. In addition, when the lid is opened, it is only necessary to rotate the cap 21 in the direction of opening the lid while the tongue piece portion 14 of the flexible ring plate 11 is pressed downward with fingers, so that there is no risk of injury to the fingers. Also, when used again (that is, when the lid is closed), the ribs 25 formed on the cap 21 are injured even if they are touched by the hand, unlike the cut-off portions having a concave and convex shape as in the conventional example. Because it is not a thing, there is no risk of injury to fingers. In addition, the ribs 13 of the flexible ring plate 11 may have a structure that can be plastically deformed or broken, and the production thereof becomes easy.

  In the above embodiment, the vertical groove 6 is formed in the lower large diameter portion 4b of the mouth portion 4, and the projecting piece 12 projects from the inner peripheral surface of the flexible ring plate 11. It is not limited to this, A protrusion may be projected from the lower large diameter portion 4 b of the mouth portion 4, and a recess may be formed on the inner peripheral surface of the flexible ring plate 11.

  Moreover, in the said embodiment, the contact area of the rib 13 of the flexible ring board 11 and the rib 25 of the cap 21 is moved by moving the rib 13 of the flexible ring board 11 below at the time of lid opening, This is smaller than when the lid is closed, thereby increasing the stress acting between the rib 13 of the flexible ring plate 11 and the rib 25 of the cap 21, thereby plastically deforming the rib 13 of the flexible ring plate 11. In the vicinity of the ribs 13, thin portions and perforations are formed so as to surround each rib 13, and the large stress is applied to the thin portions and the perforations when the lid is opened. The rib 13 of the flexible ring plate 11 and the rib 25 of the cap 21 are disengaged by cutting the thin wall portion or perforation to remove the rib 13 from the flexible ring plate 11. Also good. Further, the flexible ring plate 11 may be integrally formed on the lower large diameter portion 4 b of the mouth portion 4.

  Various plastic materials are used as the plastic material constituting the flexible ring plate 11. From the viewpoint of easily deforming or breaking the ribs 13, polypropylene (PP), high density is preferable. Polyethylene (HDPE), polyamide (PA), etc. are used.
