JP2005029232A - Cap separable from container - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a cap which prevents a user from erroneously handling a tab provided for separate refuse collection, rather than a handle for opening a discharging opening, and can easily be separated from a container mouth for separate refuse collection. <P>SOLUTION: The cap body 1 fitted over a container mouth includes: a body weakening line for cutting off a body fitted on the container mouth; a protective-part weakening line 8 for cutting off the protective part 7, which extends around the body so as to cross the body weakening line; and a tab 14 formed on the protective-part weakening line 8. For separate refuse collection, the tab 14 is handled to cut off the cap body 1 along the protective-part weakening line 8 and the body weakening line in order, thereby separating the cap body 1 from the container mouth easily. When a lid 3 is put on the cap body 1, the tab 14 cannot be handled easily. This prevents the tab 14 for separate refuse collection from being erroneously handled when the cap is opened to discharge the contents first time. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a cap body that can be easily separated from a container opening of a container filled with a content liquid during fractional collection.

Conventionally, various cap inventions that are fitted to the container mouth have various inventions in which a part of the cap body is easily broken so that the cap body can be easily separated from the container mouth in order to separate and collect the cap body. Proposed.
In general, a weakening line that can cut the body part is formed on the body of the cap body, and a part to be gripped when the cap body is separated from the container mouth is formed in a notch shape, and a fingertip is inserted into this notch. Then, by picking the end of the notch with the fingertip and pulling it outward along the weakening line, the barrel was divided to separate the container opening and the cap body.

A conventional cap body separable from the container mouth will be described with reference to FIGS.
The cap body 50 provided so as to be fitted to the conventional container mouth is connected to the lid body 3 via the hinge portion 2. The cap body 50 is formed of a cylindrical body, and a barrel portion 5 fitted into the container port between the spout 4 from which the content liquid is poured out and the peripheral wall 4a forming the spout 4, and the barrel The body weakening line 6 for cutting the body 5 in the longitudinal direction and the body 5 along the body weakening line 6 are extended from the outer peripheral surface of the body 5 across the body weakening line 6 with a gap. And a protection unit 51 to be configured.

The protective part 51 is formed with a notch 52 having a width and a depth enough to allow a fingertip to enter the position C shown in FIG. 13, and the protective part 51 is vertically disposed above the notch 52. A protective portion weakening line 53 is formed.
When the cap body 50 is separated from the container opening, a fingertip is inserted into the notch 52, and the end 54 of the notch 52 is pulled upward while being raised at the fingertip in the direction of the arrow. The protective part weakening line 53 provided in the upper part of 52 is cut from the bottom to the top. Thereafter, the gripping end portion 54 is rotated while being pulled counterclockwise to the position of the barrel weakening line 6, so that the protection portion 50 is separated from the barrel portion 5. Furthermore, if the end portion 54 is pulled upward, the body weakening line 6 is cut from the bottom to the top, and the container opening is exposed from the divided body 5, and then the cap body is easily separated from the container opening. be able to.

However, in the above-described structure, the picking portion for separating and collecting, that is, the end portion 54 of the notch portion 52 is exposed to the outside, and this end portion 54 can be easily picked with a fingertip. When opening the stopper to pour out the content liquid inside, there is a problem that the picking part for separation collection is mistakenly operated with the gripping part for opening the spout, and the cap body and the container mouth are separated. there were.
Therefore, in order to counter this problem, Patent Document 1 includes a tearing portion in which two weakening lines are formed in the longitudinal direction of the cylindrical portion engaged with the outer periphery of the mouth portion of the container, and the upper end portion thereof. There is disclosed a cap that is formed by concentrically connecting grip portions provided concentrically to each other and that is provided with an outer lid that covers the grip portion and is easy to separate and collect.

  As described above, when the picking part for separation collection is exposed to the outside, the picking part for separation collection is mistakenly operated when opening the stopper to pour out the content liquid in the container first, Inconvenience may occur. As a conventional technique for solving this problem, in the state where the easy-to-separate cap of Patent Document 1 is closed by the outer lid, the separation-collecting gripping portion is accommodated between the dispensing cylinder and the outer lid. Although it is not exposed to the outside, when the outer lid is opened, the user visually observes both the gripping part for separation collection and the pull ring for opening the spout, and accidentally operates the gripping part for separation collection. there's a possibility that. In addition, in this embodiment, when the separation and collection gripping unit is operated by mistake, the cap is divided at a stretch and the cap is separated from the container port, making subsequent use impossible.

  The present invention has been made in view of the above points, and it is unlikely that the user erroneously operates the picking part for separating and collecting with the gripping part for opening the spout, so that it can be easily removed from the container mouth during collecting and collecting. It aims at providing the cap body which can be isolate | separated.

As a means for solving the above-mentioned problems, the present invention described in claim 1 is a substantially cylindrical cap main body for mounting on a container mouth, and the cap main body is provided on a body portion. A body weakening line extending in the longitudinal direction for cutting the body part, and the body part formed integrally from the outer periphery of the body part along the body part weakening line and straddling the body weakening line A cap body that is separable from a container having a protective part extending around a gap between the protective part and a protective part weakening line for tearing the protective part in a vertical direction inside the protective part, It is characterized by providing a knob for tearing the protective part weakening line from top to bottom.
By configuring in this way, when the user first opens the stopper for pouring out the content liquid in the container, if the lid is covered with the cap body, the picking part for separation and collection is Since it is in a place where it is difficult to catch the user's eyes at the upper part of the protection part, and the grip part cannot be easily picked, there is little possibility of erroneous operation as a grip part for opening the spout. In addition, when the lid is opened, even if the user accidentally operates the sorting and collecting knob to separate the protective part, the cylinder still fitted to the container mouth at that time Since the portion is not cut, normal use is possible thereafter.

The invention described in claim 2 is the invention described in claim 1, wherein the protective portion weakening lines are provided in two places, and a space portion is formed between the cut portion formed by the protective portion weakening lines and the trunk portion. It is characterized by providing.
By comprising in this way, at the time of separation collection, a cutting part can be easily separated from a protection part, and a protection part can be divided.

The invention described in claim 3 is characterized in that, in the invention described in claim 2, the knob part is configured to protrude upward along the upper part of the cutter part.
With this configuration, at the time of separation and collection, the excision part can be easily pulled downward by the knob, and the protection part weakening lines on both sides of the excision part can be torn and the protection part can be easily divided.

The invention described in claim 4 is the invention described in claim 1, wherein the protection part weakening line is provided in the vicinity of a hinge part connecting the cap body and the lid, and the trunk part weakening line is provided in the hinge part. It is provided on the opposite side to the protection part weakening line via the, and the knob part is constituted by the hinge part or the lid.

In addition, there is a knob for tearing this protective part weakening line from top to bottom, so when the user uses the content liquid for the first time, the lid is covered with the cap body Since the picking part for separating and collecting is in a place where it is difficult to catch the user's eyes at the top of the protective part and cannot be picked easily, it is mistakenly operated first as a gripping part for opening the spout There is little possibility. In addition, when the lid is opened, even if the user accidentally operates the sorting and collecting knob to separate the protective part, it is still fitted in the container mouth at that time. Since the trunk is not cut, normal use is possible thereafter.

  According to the invention described in claim 2, two protective part weakening lines are provided, and a space part is provided between the excised part and the trunk part formed by these protective part weakening lines. The excision part can be separated from the protection part with a light force, and the end of the divided protection part can be operated to divide the body part so that the cap body can be easily separated from the container mouth.

  According to the invention described in claim 3, since the knob portion is configured to protrude upward along the upper portion of the cut portion, the cut portion is protected by pulling the knob portion downward with a light force at the time of separation and collection. The cap body can be easily separated from the container mouth by operating the end portion of the divided protective portion and dividing the barrel portion.

  According to the invention described in claim 4, the protection part weakening line is provided in the vicinity of the hinge part connecting the cap body and the lid, and the trunk part weakening line is provided on the opposite side of the protection part weakening line via the hinge part. In addition, since the knob portion is constituted by a hinge portion or a lid, the protective portion and the trunk portion can be sequentially cut with a light force, and the cap body can be easily separated from the container mouth.

Hereinafter, three best modes for carrying out the present invention will be described. First, a first embodiment of the present invention will be described with reference to FIGS. In the description of the first embodiment, the same parts as those in the conventional example and the corresponding parts will be described using the same reference numerals.
The cap body separable from the container according to the first embodiment of the present invention is formed of a synthetic resin, and is fitted into a container port (not shown) as shown in FIG. 1 and FIG. The cap body 1 is formed in a substantially cylindrical shape having a spout 4, and the lid body 3 is connected to the cap body 1 via a hinge portion 2.

As shown in FIGS. 1 and 2, the cap body 1 cuts the spout 4, the body 5 located outside the spout 4, and the body 5 provided on the body 5 in the longitudinal direction. The body weakening line 6 and the outer peripheral part of the body part 5 along the body part weakening line 6 are integrally formed and extended with a gap around the body part 5 so as to straddle the body part weakening line 6. The protection part 7 provided and the protection part weakening line 8 for tearing the protection part 7 provided in the protection part 7 in the vertical direction are schematically configured.
Further, the cap body 1 extends in the circumferential direction on the annular space 4 b formed between the outer peripheral surface of the wall portion 4 a of the spout 4 and the inner peripheral surface of the trunk portion 5, and the inner peripheral surface of the trunk portion 5. The engaging protrusion 5a is provided. And the annular space 4a of the cap main body 1 is fitted to the container mouth, and the engagement protrusion 5a provided on the inner peripheral surface of the trunk portion 5 engages with the outer peripheral surface of the container mouth being pressed.
Furthermore, the cap main body 1 is formed with a plug 20 that closes the spout 4 and a ring-shaped gripping portion 21 that cuts the periphery of the plug 20 and opens it. When the user uses the content liquid for the first time, the gripper 21 is pulled upward, and the periphery of the stopper 20 is cut off to use the content liquid.

As shown in FIGS. 3 and 4, the body weakening line 6 is composed of a thin portion 9 in which the body 5 is recessed inward in the longitudinal direction in order to cut the body 5. The thin portion 9 is composed of a wide portion 9b and a narrow portion 9a. The wide portion 9b is formed with a plurality of substantially semicircular ridges 9c projecting outward in a vertical direction with a predetermined interval. A thin film is formed between the valleys of the adjacent ridges 9c. A portion 9d is formed. In the narrow portion 9a, a thin film portion 9d 'formed slightly thicker than the thin film portion 9d is formed in the vertical direction continuously from the thin film portion 9d formed in the wide portion 9b. Are formed with an inclined wall portion 10 inclined and facing the thin film portion 9d ′, and a vertical wall portion 11 vertically facing the thin film portion 9d ′. The vertical wall portion 11 serves as a base portion of the protection portion 7 that is erected from the trunk portion 5.
In the first embodiment, the structure of the body weakening line 6 described above is employed, but the structure is not limited to this structure as long as the body 5 can be easily cut.

  As shown in FIGS. 1 and 2, the protective portion 7 provided integrally with the trunk portion 5 at the vertical wall portion 11 is a belt-like body that surrounds the trunk portion 5 at the same height. That is, the protection part 7 is connected in the vertical direction along the trunk part weakening line 6 provided on the outer peripheral part of the trunk part 5, and the upper side of the protection part 7 is easily cut at the upper end of the trunk part 5. Connected by the upper wall 12 (the range from the trunk weakening line 6 to the protective weakening line 8 in the counterclockwise direction in FIG. 2) and at a predetermined interval from the outer peripheral surface of the trunk 5 Is extended around the entire circumference. In addition, a lid 3 that opens and closes the cap body 1 is connected to the protection portion 7 via a hinge portion 2.

As shown in FIG. 2, the protective part 7 has a single protective part weakening line 8 for cutting the protective part 7 in the longitudinal direction from the position of the trunk weakening line 6 to a position of approximately 135 degrees in the clockwise direction. As shown in FIGS. 5 and 6, a knob portion 14 is formed above the protective portion weakening line 8.
As shown in FIG. 2, the protective part weakening line 8 is formed by forming a substantially V-shaped groove part in the longitudinal direction on the inner peripheral wall of the protective part 7 in a vertical direction, thereby thinning the peripheral wall of the protective part 7. Has been.
As shown in FIGS. 5 and 6, a concave portion 13 is connected to the upper portion of the protective portion weakening line 8, and the curved right side wall portion of the concave portion 13 is configured as a knob portion 14. Further, in a predetermined circumferential range including the range of the concave portion 13, an upper wall 12 that connects the protective portion 7 and the trunk portion 5 is drilled to form a space portion 15.

  Therefore, when the cap body 1 is covered with the lid 3, as shown in FIG. 5, the concave portion 13 is very small and hardly noticeable to the user's eyes. Therefore, the fingertip cannot be easily put into the opening portion of the recess 13.

Next, referring to FIG. 1 and FIG. 2, a method of separating the cap body fitted to the container according to the first embodiment of the present invention from the container mouth after using the content liquid is also referred to. While explaining.
First, the knob portion 14 connected to the protective portion weakening line 8 of the protective portion 7 is picked from above with a fingertip, is raised obliquely as shown by the arrow, and is pulled to turn the knob portion 14 to be protected. The protective portion 7 is divided while the partial weakening line 8 is cut from the top to the bottom.
Next, the gripping part 14 or the end of the divided protection part 7 opposite to the hinge part 2 side is gripped, and the protection part 7 and the body part are rotated counterclockwise while gently pulling outward. 5, the protective portion 7 and the trunk portion 5 are separated within a range of approximately 225 degrees up to the position of the trunk portion weakening line 6 (the position of the base portion of the protective portion 7).
Further, when the position of the body weakening line 6 is reached, the body weakening line 6 is torn up from the bottom by pulling up the gripping end part outwardly, and the body part 5 is weakened. It can be divided along the line 6 in the longitudinal direction.
Thus, if the trunk | drum 5 located in the outer periphery of a container opening is cut | disconnected longitudinally and a part of surrounding wall of a container opening is exposed, a cap body can be easily removed from a container opening after that.

Next, a cap body separable from the container according to the second embodiment of the present invention will be described with reference to FIGS. In the description of the second embodiment, only the differences from the first embodiment will be described below in comparison with the first embodiment.
In the protective part 7, in FIG. 8, two protective part weakening lines 8, 8 for cutting the protective part 7 in the vertical direction are formed at small intervals at a position of approximately 135 degrees in the clockwise direction from the trunk weakening line 6. Has been.
As shown in FIGS. 7 to 9, a portion sandwiched between the two protection portion weakening lines 8, 8 becomes a resection portion 17 that is excised from the protection portion 7. Protrudes upward. In the range where the cut portion 17 is formed, an upper wall 12 that connects the cut portion 17 and the trunk portion 5 is formed to form a space portion 15.
In addition, although the knob | pick part 14 is formed in the substantially rectangular shape by the side view, as shown with the dashed-dotted line of FIG. 9, it is substantially T-shaped or substantially L-shaped so that a user may pick up easily with a fingertip. It may be formed.

  As shown in FIG. 7, the lid 3 is formed with a recess 19 that accommodates the knob 14 at a position corresponding to the knob 14 connected to the cutter 17. When the handle is crowned, the knob 14 is housed in the recess 19 of the lid 3 and is not exposed to the outside.

Next, a method of separating the cap body fitted to the container according to the second embodiment of the present invention from the container mouth after using the content liquid will be described with reference to FIGS. 9 and 10.
First, the knob 14 connected to the excision part 17 is picked, pulled outward and downward, and the excision parts 17 integrated with the knob 14 are provided with the protection part weakening lines 8 provided at both ends thereof. , 8 is cut from the top to the bottom and separated from the protective portion 7, a part of the protective portion 7 is divided in a state where the width of the cut portion 17 is removed vertically.
Next, the end portion 7a opposite to the hinge portion 2 side of the cut protective portion 7 is gripped and operated in the same manner as in the first embodiment, so that the body portion 5 located on the outer periphery of the container mouth is moved. By tearing along the body weakening line 6 and exposing a portion of the peripheral wall of the container mouth, the cap body can be easily removed from the container mouth.

In the first and second embodiments described above, when the user first opens the plug 20 for pouring the content liquid in the container, the lid 3 is covered with the cap body 1. In both the first and second embodiments, it is not possible to easily pick the picking portion 14 for separation and collection, and therefore there is little possibility of erroneous operation with the stopper 20 for dispensing the content liquid.
In addition, when the lid 3 is opened, both the gripping portion 21 that opens the plug 20 that closes the spout 4 and the sorting collection knob 14 are exposed to the outside. In the second embodiment, even when the user accidentally operates the sorting and collecting knob 14 to tear the protective portion 7, at that time, the trunk portion 5 fitted to the container mouth is not torn. Therefore, it can be used as usual after that.

Next, a cap body separable from the container according to the third embodiment of the present invention will be described with reference to FIGS. In the description of the third embodiment, only the differences from the first and second embodiments will be described below in contrast to the first and second embodiments.
A protective part weakening line 8 is formed in the protective part 7 at a position substantially connected to one end (the upper end in FIG. 11) of the hinge part 2, and a position opposite to the protective part weakening line 8 via the hinge part 2, that is, A body weakening line 6 is formed on the body 5 at a position of approximately 75 degrees in the clockwise direction from the protection part weakening line 8.
