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. 14 and 15 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 portion 44. An annular band portion 45 disposed at a lower end side of the ring portion 45 and an end (in the circumferential direction) of the circumferential wall portion 44 and the band portion 45 disposed between the circumferential wall portion 44 and the band portion 45. And a connecting portion 46 that connects the peripheral wall portion 44 and the band portion 45, and the peripheral wall portion 44 and the band portion 45 are detachably connected (with the connecting portion 46 left). 1 bridge part 47 and the 2nd bridge part 48 which is formed between the (circumferential direction) both ends of the said band part 45, and connects these both ends so that separation | detachment is possible.

Then, 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. 15). Further, in the case of using again (that is, closing again after opening), the band portion 45 is removed from the peripheral wall portion 44 by cutting the connecting portion 46 or the like, and then the cap 42 is removed from the mouth portion 41a. (See, for example, Patent Document 1).
Japanese Patent Laying-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.

  The present invention has been made in view of such circumstances, and when the cap is removed from the mouth of a container such as a bottle and then used again, the cap can be directly attached to the mouth. The purpose is to provide a container with a cap that does not cause injury to fingers during installation.

  In order to achieve the above object, a container with a cap according to the present invention includes a container, an inner plug fitted to the mouth portion of the container, and a cap fitted to the inner plug so as to be rotatable in the circumferential direction. And the inner plug is configured to be detachable from the upper part of the mouth part, an annular hem part fixed to the lower part of the mouth part, and between the canopy part and the annular hem part. A band-shaped cut-out part that is detachably connected to the canopy part and the annular skirt part, and a protrusion is formed on the outer periphery of the band-like cut-off part, and the cap is engaged with the protrusion. An engagement hole is formed, an engagement portion is formed in the circumferential direction on the outer peripheral surface of the canopy portion, and an engaged portion that is engaged with the engagement portion is formed on the inner peripheral surface of the cap. The protrusion that engages with the engagement hole is moved in the circumferential direction by rotating the cap in the circumferential direction, thereby The release portion takes a configuration that is configured so that it can successively separated from the above canopy portion and the annular skirt.

  That is, the container with a cap of the present invention, when closed, is fitted with an inner plug at the mouth of the container, with the canopy portion and the annular hem connected by a band-shaped cut-off portion, A cap is externally fitted so as to be rotatable in the circumferential direction. In this state, the canopy portion is configured to be detachable from the upper portion of the mouth portion, but since the annular skirt portion is fixed to the lower portion of the mouth portion, the annular hem portion is provided with a strip-shaped separation portion. The connected canopy cannot be pulled upward. Therefore, the cap engaged with the canopy portion (by engagement between the engaging portion and the engaged portion) cannot be lifted upward to open the cap. When opening the lid from such a closed state, while holding the container with one finger, the cap is gradually rotated in the circumferential direction with the other finger, and this rotation causes the engagement hole of the cap to be engaged. The projecting portion of the band-shaped separation portion to be combined is gradually moved in the circumferential direction, and thereby the belt-shaped separation portion is pulled in the circumferential direction to sequentially separate from the canopy portion and the annular skirt portion. And in the state which cut | disconnected all the strip | belt-shaped cutting | disconnection parts, since the canopy part is isolate | separated completely from the cyclic | annular skirt part, a cap can be pulled upwards with a canopy part, and it can remove and open from the said opening part.

  As described above, in the container with a cap of the present invention, when the lid is opened, the entire strip-shaped separating portion must be separated from the canopy portion and the annular skirt portion and removed from the inner plug. The protrusion of the strip-like cut-off portion is not engaged with the engagement hole of the cap. Therefore, when opening the lid, depending on whether the protrusion of the strip-like cut-off part is exposed from the engagement hole of the cap or not, it has been opened once or is still opened. It ’s easy to see if it ’s ever happened. In addition, since the belt-like cut-off portion is all cut off when the lid is opened, the cap can be attached to the mouth of the container together with the canopy portion when it is used again (that is, closed). In addition, the work for separating the strip-shaped separation part can be performed by operating the cap with the other finger while holding the container with one finger, so there is no need to touch the strip-shaped separation part with the finger, and the finger is injured during the above separation work. There is no fear. Moreover, since the inner plug is externally fitted with a cap, the cut-off portion between the strip-like cut-out portion, the canopy portion, and the annular skirt portion is hidden by the cap, and there is no risk of injury to fingers when used again. In addition, the cap can be decorated such as painting and vapor deposition, giving a high-class feeling.

  Further, in the present invention, the canopy portion and the strip-like cut-off portion are connected by an upper thin portion, the annular skirt portion and the strip-like cut-out portion are connected by a lower thin portion, and the width of both the thin portions is 0.2. When the thickness is set within a range of 0.2 to 1.0 mm within a range of ~ 2.0 mm, an operation of separating the canopy portion and the strip-shaped separation portion, and an annular skirt portion and a strip-shaped separation portion, It is possible to smoothly perform the work of cutting off, which is preferable.

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

  Reference numeral 11 denotes a synthetic resin inner plug fixed to the mouth 4 of the container 1 in an outer fitting manner. As shown in FIGS. 5 and 6, a dome-shaped cylindrical canopy 12 and an annular ring A skirt 13 and a belt-like virgin seal (band-like separating portion) 14 that is detachably connected to the canopy 12 and the annular skirt 13 in a state of being bent into a substantially annular shape. The canopy portion 12 includes a ceiling wall 15 and a peripheral side wall 16, and an annular plug portion 17 that is fitted into the mouth portion 4 in a sealed manner is suspended from the lower surface of the ceiling wall 15. Further, on the inner peripheral surface of the upper end portion of the peripheral side wall 16, a single annular groove that engages with the convex strip 5 of the mouth portion 4 so as not to rotate in the circumferential direction and to be detachable in the vertical direction. 16a is formed. In this embodiment, the ridge 5 of the mouth portion 4 and the groove 16a of the peripheral side wall 16 are engaged so as not to rotate in the circumferential direction. In this case, the ridge 5 and the groove 16a are The sliding resistance in the circumferential direction is set so large that the circumferential side wall 16 is not pulled in the circumferential direction against the force that pulls the virgin seal 14 in the circumferential direction when the lid is opened, which will be described later. If it is, it is enough. Further, on the outer peripheral surface of the lower end portion of the peripheral side wall 16, a single annular groove (engagement portion) 16b is formed in the circumferential direction.

  The annular skirt 13 is engaged with a portion of the inner peripheral surface corresponding to the recess 6 of the mouth 4 so as to be unable to move up and down in the recess 6 and not to rotate in the circumferential direction of the mouth 4. One or one (in this embodiment, one) convex portion 13a is projected.

  The virgin seal 14 is interposed between the canopy portion 12 and the annular skirt portion 13, and the upper end surface of the virgin seal 14 and the lower end surface of the canopy portion 12 are connected by a detachable upper thin portion 18. In addition, the lower end surface of the virgin seal 14 and the upper end surface of the annular skirt 13 are connected by a detachable lower thin portion 19. The widths of the upper and lower thin portions 18 and 19 are set in a range of 0.2 to 2.0 mm, and preferably in a range of 0.2 to 1.0 mm. Further, the thickness is set within a range of 0.2 to 1.0 mm, and preferably within a range of 0.2 to 0.8 mm. Further, the virgin seal 14 is provided with a projecting portion (protrusion portion) 14a on the outer surface of one end portion thereof (the end portion on the start end side in the opening direction among both end portions in the circumferential direction), which will be described later. The cap 21 is engaged with the cutout hole 23.

  21 is a synthetic resin cap (see FIG. 1 and FIG. 2), and its surface is decorated (not shown) by painting, vapor deposition or the like. The cap 21 is formed in a substantially cylindrical shape as shown in FIGS. 7 to 10, and cannot move up and down in the groove 16 a of the canopy portion 12 of the inner plug 11 on the inner peripheral surface thereof. In addition, a single annular ridge (engaged portion) 22 is provided so as to project in a freely rotatable manner. The cap 21 is formed with a notch hole (engagement hole) 23 at a portion corresponding to the convex portion 14 a of the virgin seal 14 so as to extend from the lower end surface of the virgin seal 14. The convex portion 14a is engaged with the upper portion of the notched hole portion 23 (see FIGS. 11 to 13).

  Further, the cap 21 is provided with an operating portion 24 projecting from the outer peripheral surface of the lower end portion at a predetermined distance from the notched hole portion 23, and a cap or the like is applied to the operating portion 24 with a thumb or the like. 21 is rotated in the lid opening direction (in this embodiment, the counterclockwise direction is the arrow direction in FIG. 1), so that the left side surface of the convex portion 14 a of the virgin seal 14 is positioned above the notch portion 23. Pushing it on the left side and rotating it in the opening direction, and accordingly moving the virgin seal 14 in the opening direction, cutting the thin portions 18 and 19, and from the canopy portion 12 and the annular skirt portion 13. It can be separated.

  In the above configuration, in the closed state, the inner plug 11 is externally fitted and fixed to the mouth portion 4 of the container 1, and the cap 21 is externally fitted and fixed to the inner plug 11 so as to be rotatable in the circumferential direction. ing. In this fixed state, the canopy portion 12 and the annular skirt portion 13 of the inner plug 11 are connected via the virgin seal 14, and the annular skirt portion 13 is fixed to the mouth portion 4 so as not to move up and down. Therefore, the inner plug 11 and the cap 21 are fixed to the mouth portion 4 so as not to move up and down.

  When the cap 21 is opened from this closed state, the cap 21 is rotated from the state shown in FIG. 1 in the opening direction (the arrow direction in FIG. 1), and this rotation causes the notch 23 of the cap 21 to be opened. The convex portion 14a of the virgin seal 14 to be engaged is rotated in the opening direction to separate the virgin seal 14 from the canopy portion 12 and the annular skirt portion 13, and then the cap together with the canopy portion 12 separated from the annular skirt portion 13 21 is lifted upward and removed from the mouth 4 to open the lid.

  Thus, in the above embodiment, when the lid is opened, the entire virgin seal 14 must be separated from the canopy portion 12 and the annular skirt portion 13 and removed from the inner plug 11. The convex portion 14 a of the virgin seal 14 is not engaged with the notched hole portion 23 of the cap 21. Therefore, when the lid is opened, whether the convex portion 14a of the virgin seal 14 is exposed from the notch hole portion 23 of the cap 21 or not, has been opened once, You can easily see if it has never been opened. Moreover, since all the virgin seals 14 are separated when the lid is opened, the cap 21 can be attached to the mouth portion 4 of the container 1 together with the canopy portion 12 when it is used again (that is, when the lid is closed). Further, since the work for separating the virgin seal 14 can be performed by operating the cap 21 with the other finger while holding the container 1 with one finger, it is not necessary to touch the virgin seal 14 with the finger, There is no risk of injury. Moreover, since the inner plug 11 is externally fitted with the cap 21, the separation part between the virgin seal 14, the canopy portion 12, and the annular skirt portion 14 is hidden by the cap 21, and the finger is injured when used again. There is no fear. Moreover, since the cap 21 is subjected to decoration processing such as painting and vapor deposition, a high-class feeling can be obtained.
