JP5199043B2 - Hinge cap - Google Patents

Description

  The present invention relates to a hinge cap that can be visually checked for the presence or absence of unauthorized removal from a container and can be separated and disposed by being separated from a container mouth.

In a conventional hinge cap, the outer peripheral surface of the container mouth is surrounded by a peripheral wall, and a lid is connected to the rear half area of the peripheral wall via a hinge. The lid is pulled sideways from the open state. After making the cut at the upper end of the peripheral wall, the cover body is further pushed downward to partially peel off the peripheral wall, so that when the cover body is pulled up, the peripheral wall is easily bent. Yes (see, for example, Patent Document 1).
JP-A-11-49211

  In such a hinge cap, a part of the peripheral wall is peeled off in a thin skin shape, so that it is possible to visually confirm that an illegal removal from the container has been performed.

  However, when the conventional hinge cap is removed, as described above, after the lid is pulled sideways from the opened state, it is necessary to perform a pre-process for further pressing the lid downward. For this reason, there exists a problem that the operation | work of separation disposal becomes complicated.

  The object of the present invention is that when an unauthorized removal from the container is performed, it can be confirmed by visual observation, while in the case of separation and disposal, the container is not subjected to complicated work steps. An object of the present invention is to provide a hinge cap that can be separated from the mouth.

The present invention has a ceiling wall disposed on the upper side of the container mouth portion, and a peripheral wall that hangs from the outer edge of the ceiling wall and surrounds the outer peripheral surface of the container mouth portion, and a protrusion formed on the inner peripheral surface of the peripheral wall a body fixed to the container mouth portion but fitted to the outer peripheral surface of the container mouth part, and an auxiliary wall extending along the circumferential direction at least a portion of the half area after said peripheral wall, the auxiliary wall A lid connected via a hinge and capable of opening and closing the top wall of the main body,
Each of the circumferential ends of the auxiliary walls is connected to the rear half region ,
In this rear half area, two first scheduled cutting lines that allow the rear half area to be cut along its vertical direction, and two circumferential ends of the auxiliary wall connected to the first scheduled cutting line Are provided with two second scheduled cutting lines that allow the rear half region to be cut along the circumferential direction so as to approach each other and form a leftover portion between the circumferential ends ,
Along with the pulling from the auxiliary wall, a part of the rear half area cut open from the circumferential end can be deformed outward from the remaining portion as a base point. Is.

  If the planned cutting line has a structure that cuts a part of the area toward each other starting from the two circumferential ends as the auxiliary wall is pulled, the layout can be changed variously. However, it is preferable that the first planned cutting line cuts the protrusion in the vertical direction. As such a cutting planned line, what constituted the 1st cutting planned line so that cutting from the upper end or lower end of a peripheral wall to the above-mentioned projection is mentioned, for example.

  In addition, examples of the planned cutting line include those formed by a thin portion that can be broken, and those obtained by intermittently connecting separation lines that form a gap formed in advance by slits or the like with a breakable connecting piece. It is done.

  The circumferential end of the auxiliary wall is preferably connected so that the auxiliary wall covers the entire rear half region. However, according to the present invention, it is not always necessary to cover the entire rear half region. May be connected so as to occupy an area smaller than the rear half area. In other words, the auxiliary wall only needs to extend in the circumferential direction in at least a partial region of the rear peripheral wall.

  According to the present invention, by pulling with the lid open, the second half of the peripheral wall that fits to the outer peripheral surface of the container mouth is along the circumferential direction with the two circumferential ends as base points. It is cut open to deform outward. That is, a part of the rear peripheral wall that is cut open from the two circumferential ends, respectively, with the pulling from the auxiliary wall starting from the remaining portion between the two circumferential ends of the rear peripheral wall. Deform outward. For this reason, when the illegal removal action from a container is performed, it can be confirmed visually.

  In addition, when separating and discarding the hinge cap from the container mouth portion, if the lid is pulled in an open state, the second half region will be deformed outward along the circumferential direction from the two circumferential ends. Therefore, if the cut-opening is configured so that part of the fitting with the outer peripheral surface of the container mouth portion by the protrusion formed on the inner peripheral surface of the peripheral wall is released, the fitting force of the main body is weakened. If the lid is pulled up as it is, the hinge cap can be separated from the container mouth portion without pushing down the lid further downward as in the prior art.

  Therefore, according to the present invention, when an illegal detaching action from the container is performed, it can be visually confirmed. On the other hand, when separating and discarding, the container mouth is not subjected to a complicated work process. A hinge cap that can be separated from the portion can be provided.

  In particular, the planned cutting line is connected to the first planned cutting line that enables cutting from the upper end or the lower end of the peripheral wall to the projection, and the circumferential end of the auxiliary wall is used as a base point. If each is constituted by a second scheduled cutting line that is cut while approaching each other, it is possible to easily remove the container from the container mouth, and to prevent the unauthorized removal from the container itself.

  Hereinafter, a hinge cap according to the present invention will be described in detail with reference to the drawings.

  Reference numeral 2 denotes a main body fixed to the container mouth. The main body 2 surrounds the outer peripheral surface of the container mouth portion 21 by hanging from the top wall 2a disposed above the mouth portion (hereinafter referred to as “container mouth portion”) 21 of the container 20 and the outer edge of the top wall 2a. And a peripheral wall 2b.

The top wall 2a, pouring cylinder 2a ₁ is erected integrally, on its inner side, it is provided sealing plug 2a ₃ comprising a pull ring 2a ₂ together. The sealing plug 2a ₃ is integrally connected to the inside of the dispensing tube 2a ₁ through a thin portion 2a ₄ that can be broken by pulling up the pull ring 2a ₂ . Accordingly, when the sealing plug 2a ₃ is pulled up using the pull ring 2a ₂ , the thin portion 2a ₄ is cut, so that a spout leading to the inside of the container is formed inside the spout cylinder 2a _1. The

The peripheral wall 2b is formed with a recess 3n whose outer peripheral surface is recessed radially outward in the vertical direction along the axis O. Thus, the peripheral wall 2b is disposed on the front half side of the container mouth portion 21, and is disposed on the front half region (hereinafter referred to as “front peripheral wall”) 2b ₁ covering the front half and on the rear half side of the container mouth portion 21. And a rear half region (hereinafter referred to as “rear side wall”) 2b ₂ covering the rear half.

As shown in FIG. 5 (a), the front peripheral wall 2b ₁ has a double structure in which a recess opening on the lower end side is formed inside, and the outer peripheral surface of the container mouth portion 21 is formed on the inner peripheral surface thereof. A protrusion 2c ₁ is formed to be fitted to the engaging protrusion 21p provided on the surface. A projection 2c ₂ that fits into an engagement projection 21p provided on the outer peripheral surface of the container mouth portion 21 is also formed on the inner peripheral surface of the rear peripheral wall 2b ₂ .

Reference numeral 3 denotes an auxiliary wall extending along the circumferential direction of the rear peripheral wall 2b ₂ . As shown in FIG. 3, the circumferential ends 3 a of the auxiliary walls 3 are connected to each other with an interval in the circumferential direction of the rear peripheral wall ₂ b ₂ . Further, the auxiliary wall 3 is also integrally connected to the rear peripheral wall 2b ₂ through a plurality of breakable connecting pieces 7 arranged around the axis O also in the vicinity of the front lower end. Thus, the auxiliary wall 3 is arranged to produce a gap S between the way, the rear wall 2b ₂ shown in FIG.

Reference numeral 4 a is a first scheduled cutting line that enables cutting from the lower end of the rear peripheral wall ₂ b ₂ to the protrusions 2 c ₁ and 2 c ₂ along the axis O in accordance with the tension from the auxiliary wall 3. The first cutting line 4a is provided as a front wall 2b ₁ and the rear wall 2b ₂ and the peripheral wall connecting portion 2b ₃ breakable connecting the. Further, reference numeral 4b is a second which leads to the first cutting line 4a, respectively starting from the circumferential end 3a of the auxiliary wall 3, extending along the circumferential direction of the rear wall 2b ₂ so as to approach each other This is the planned cutting line.

Thereby, the rear side peripheral wall 2b ₂ can be opened by the planned cutting lines 4a and 4b by the rear side peripheral wall 2b ₂ being extended outward from the circumferential end 3a as the auxiliary wall 3 is pulled. Note that the planned cutting line 4a can be replaced with a separation line formed in advance by a slit or the like. In this case, the rear peripheral wall 2b ₂ can be easily opened only by cutting the planned cutting line 4b.

The planned cutting lines 4a and 4b are breakable thin portions or separation lines formed in advance by slits or the like, and the rear peripheral wall 2b ₂ is based on the circumferential end 3a as the auxiliary wall 3 is pulled. to that intermittently connected by breakable connecting piece by being stretched outwardly, or, in the rear wall 2b ₂ may be intermittently formed a plurality of slits (cut line).

Reference numeral 5 denotes a lid that is integrally connected to the auxiliary wall 3 via a hinge 6 and that can open and close the top wall 2a. As described above, each of the first scheduled cutting line 4a and the second scheduled cutting line 4b is cut by extending the rear peripheral wall 2b ₂ outward from the circumferential end 3a as a base when the auxiliary wall 3 is pulled. . For this reason, the lid 5 functions as an operation piece that causes the auxiliary wall 3 to be pulled by opening and pulling the lid 5.

Circumferential end 3a of the auxiliary wall 3, the auxiliary wall 3 is rear half area, i.e., it is preferably connected to cover the entire rear wall 2b _2, according to the present invention, covering the entire second half region This is not always necessary, and the auxiliary wall 3 may be connected so as to occupy an area smaller than the rear half area. That is, the auxiliary wall 3 only needs to extend along the circumferential direction in at least a partial region of the rear peripheral wall 2b ₂ .

In the present invention, the front half region and the rear half region are defined as the front side F and the rear side R, respectively, with the hinge 6 side and the side opposite to the hinge 6 centered on the cap axis O, respectively. With respect to the longitudinal axis extending toward the rear side R, the axis O is defined as the right side S _R and the left side S _L , respectively, extending vertically from the base point. In other words, the front half region is referred to as the front left and right 180 ° region around the axis O, and the rear half region is referred to as the rear left and right 180 ° region around the axis O.

According to the present invention, when the lid 5 is opened, for example, when pulled in the direction shown by the arrow in the drawing, after the plurality of connecting pieces C are sequentially cut, the first cutting planned line 4a is also broken. As a result of the breakage of the first planned cutting line 4a, a part of the rear peripheral wall 2b ₂ along the second planned cutting line 4b is also circumferential with respect to the two circumferential ends 3a as shown in FIG. Is cut open so as to flip outward. That is, part of the side wall 2b ₂ after cut open from the two circumferential ends 3a, respectively, as shown in FIG. 4, piercer existing between each other of the two circumferential direction end 3a of the rear wall 2b ₂ With the remaining portion A as a base point, it reverses outward as it is pulled from the auxiliary wall. For this reason, when an unauthorized removal from the container is performed, it can be visually confirmed as shown in FIG.

In addition, when the hinge cap 1 is separated and discarded from the container mouth portion 21, if the lid 5 is pulled in an open state, the rear peripheral wall 2b ₂ is removed along the circumferential direction from the two circumferential ends 3a. As shown in FIG. 4, part of the fitting with the outer peripheral surface of the container mouth portion 21 by the projection 2c ₂ formed on the rear peripheral wall 2b ₂ is released because it is cut open so as to be reversed in the direction. As a result, the fitting force of the main body 2 is weakened. Therefore, if the lid body 5 is pulled up as it is, the hinge cap 1 can be separated from the container mouth portion 21 without pushing down the lid body 5 as in the prior art. Can do.

  Therefore, according to the present invention, when an illegal detaching action from the container is performed, it can be visually confirmed. On the other hand, when separating and discarding, the container mouth is not subjected to a complicated work process. A hinge cap that can be separated from the portion 21 can be provided.

In particular, as in the present embodiment, a first cutting planned line 4a that causes a cut from the lower end of the rear peripheral wall 2b ₂ to the projection 2c ₂ and a circumferential end 3a that is connected to the first cutting planned line 4a are used as base points. If it comprises with the 2nd scheduled cutting line 4b cut | disconnected while approaching mutually, the removal action from an unauthorized container itself can be suppressed, making separation from the container opening part 21 easy.

  The connecting piece 7 can be broken by pulling the auxiliary wall 3. Thereby, the wobbling of the auxiliary wall 3 that occurs during use until the hinge cap 1 is disposed and discarded can be suppressed.

  The above is a preferred embodiment of the present invention, but various modifications can be made within the scope of the claims.
