Description

  The present invention relates to a hinge cap.

  As a cap used for a bottle, a tube container or the like, a hinge cap in which a cap body and an upper lid are connected by a hinge has already been widely known. The hinge cap has an upper lid connected to the cap body, so there is no risk of losing the upper lid, and it can be opened and closed with one hand, so that it is easy to use.

  Further, a pull-open type cap is known as a structure that is provided with a cap and can be opened, and can be opened and sealed many times after opening. In this pull-open type cap, a removable portion for forming an opening in the cap body is formed, and the cap body and the removable portion are connected and integrated by a score formed of a groove-shaped thin portion. A column is provided integrally with the removable part, and a pull ring is provided integrally with the tip of the column. When opening, the finger is inserted into the pull ring and pulled up, thereby breaking the score and separating the removable portion from the cap body.

  However, in this pull-open type cap, a finger must be inserted into a narrow place where a pull ring is provided at the time of opening, and a relatively large force is required for the operation of inserting the finger into the pull ring and pulling it up, It has the disadvantages that it is difficult for elderly people to open and is not always convenient.

  As a cap that can improve such disadvantages, there is a cap disclosed in Patent Document 1. In this cap, an open lid body in which a ring-shaped release operation piece is integrally formed is mounted above the cap via a thin weakening line portion. Moreover, the cutting blade which protrudes below in a substantially cylindrical shape is provided in the inside of the lid. At the time of opening, after cutting off the ring-shaped free operation piece from the outside of the cap along the circumferential direction, the lid with the cutting blade is pushed down, and a part of the weakened cutting line provided inside the cap is broken. Further, the lid piece is cut by rotating the lid. In addition, the cut | disconnected cover piece is latched by the cyclic | annular protrusion provided in the inside of an open body.

  With this cap, at the time of opening, an operation of cutting the ring-shaped release operation piece from the outside of the cap along the circumferential direction, an operation of pushing down the opening body with the cutting blade, and an operation of rotating the opening body Can be opened in order. Therefore, when this cap is used, the operation of inserting a finger into a narrow place where the pull ring is provided or the operation of inserting the finger into the pull ring and pulling it up is not necessary. Can be opened with force.

  As a cap structure similar to Patent Document 1, a ring-shaped inner plug that can be cut through a thin portion is integrally formed below the main body cap, and a blade (guide cylinder) is formed inside the main body cap. Is formed in Patent Document 2. Even with this cap, at the time of opening, the operation of cutting the ring-shaped inner plug along the circumferential direction from the outside of the cap, the operation of pushing down the main body cap with the blade (guide tube), and the operation of rotating the main body cap Can be opened in order.

  However, according to the cap structures disclosed in Patent Document 1 and Patent Document 2, the operation of cutting the ring-shaped free operation piece and the inner plug along the circumferential direction, and the lid and blade with the cutting blade In addition to the operation of pushing down the main body cap provided with the (guide cylinder), an operation of rotating the lid and the main body cap and cutting the weakened line portion with the cutting blade or the blade (guide cylinder) is necessary. For this reason, it takes a lot of labor and time, and there is a possibility that it is difficult for an elderly person or the like who is difficult to exert a great force when rotating the lid or the body cap to open.

  The present invention solves the above-described problems, and provides a hinge cap that can perform an unsealing operation without much trouble and time and without difficulty even for a person who is difficult to exert a large force such as an elderly person. It is intended.

  In order to solve the above-mentioned problems, a hinge cap according to the present invention has a cap body having a spout and an upper lid connected by a hinge, and a spacer that is connected to the upper lid or the cap body via a thin portion and is separable. Is placed so that it is located between the cap body and the upper lid, and an inner plug is connected to the spout of the cap body via a weakening line portion. Is provided with an upper lid coupling portion that can be coupled to the inner plug, and the spacer is positioned at the right end portion or the left end portion of the hinge cap in a state where the upper lid is put on the cap body. As seen from the side, it is formed in a flat and substantially triangular shape with the side on which the hinge is provided as the top, and the spacer is separated from the upper lid or the cap body, and the upper lid is pushed down. Ri, inside plug is coupled to the upper cover coupling part, by opening the upper cover in this state, the inner plug is characterized in that it is configured to be separated from the cap body.

  In the above-described configuration, the inner plug is coupled to the upper lid coupling portion by separating the spacer from the upper lid or the cap body in a state where the upper lid is put on the cap body and pushing down the upper lid. Further, by opening the upper lid from this state, the inner plug is separated from the cap body. Thus, according to the said structure, only the isolation | separation operation | movement from the upper cover or cap main body of the said spacer and the lowering operation | movement of an upper cover are performed, and an inner cover can be isolate | separated from a cap main body by opening an upper cover after that. Therefore, at the time of opening, it is not necessary to rotate the opening body or the main body cap and cut the weakened wire portion with a cutting blade or blade (guide cylinder), and the opening operation can be performed with less effort and time. Even people who are difficult to exert great power, such as elderly people, can perform the opening operation without hindrance.

  Further, the present invention is characterized in that the upper end portion of the inner plug is configured to be fitted and coupled to a cylindrical portion provided in the upper lid coupling portion. Further, the present invention is characterized in that an upper lid coupling portion is formed so that the inner plug is attached in a horizontal posture with respect to the upper lid that is inclined and closed with the spacer removed. As described above, when the upper lid coupling portion is formed, even when the spacer is removed and the upper lid is inclined and closed, the inner plug is in close contact with the pouring spout of the cap main body in a good posture. It will be.

  The present invention is characterized in that a tab that can be gripped is formed on the spacer. Thus, when the tab which can be hold | gripped in the said spacer is formed, the said spacer can be more easily removed holding a tab at the time of opening.

  According to the present invention, the spacer disposed between the cap body and the upper lid is separated from the upper lid or the cap body, and the upper lid is pushed down so that the inner plug is coupled to the upper lid coupling portion. By opening the lid so that the inner plug is separated from the cap body, when opening, the lid and body cap are rotated to cut the weakened wire section with a cutting blade or blade (guide cylinder). The opening operation can be performed with little effort and time without being necessary, and even a person who is difficult to exert a great force such as an elderly person can perform the opening operation without any trouble, thereby improving convenience. Further, the shape of the spacer when viewed from the side, with the side on which the hinge is provided as a top, formed into a flat and substantially triangular shape, with the spacer separated, the upper lid The inner plug can be firmly connected to the upper lid coupling portion of the upper lid, and after that, when the upper lid is opened, the inner plug can be more reliably prevented from coming off from the upper lid coupling portion of the upper lid. Reliability is improved.

  In addition, with the spacer removed, by forming the upper lid coupling portion so that the inner plug is attached in a horizontal posture with respect to the upper lid that is inclined and closed, the spacer is removed and the upper lid is inclined. Even when closed, the inner plug will be in close contact with the spout of the cap body in a good horizontal posture, and the contents can be well prevented from leaking outside with the top lid closed, Reliability is improved.

  As shown in FIGS. 1 to 4 and the like, the hinge cap 10 according to the embodiment of the present invention is made of a synthetic resin such as polyethylene having elastically deformable properties, and is capped by the cap body 11 and the hinge 12. The upper lid 13 coupled to the main body 11 is integrally formed. The cap body 11 is mounted and fixed by being plugged into the mouth 2 at the upper end of the bottle 1 as a container shown in FIGS. 4A and 4B. The bottle 1 is formed of a material harder than the hinge cap 10 such as glass or polyethylene terephthalate.

  The cap body 11 has an annular skirt wall 14 having a projection 15 formed along the inner peripheral surface, and the skirt wall 14 is fitted on the mouth 2 of the bottle 1. Further, an inner ring 16 is integrally formed on the cap body 11, and the hinge cap 10 is attached to the bottle 1 in a state where the inner ring 16 enters the inside of the mouth 2 at the upper end of the bottle 1.

  The upper edge portion of the inner ring 16 in the cap body 11 is connected to the upper edge portion of the skirt wall 14, and the outer peripheral diameter thereof is formed to be slightly smaller so as to be elastic with respect to the outer peripheral lower edge portion of the upper lid 13. The cap body 11 is connectable to the outer periphery of the upper surface portion 18 provided in a disc shape. A spout 19 that protrudes upward in a cylindrical shape is integrally formed at the center of the upper surface 18 of the cap body 11.

  The hinge cap 10 is manufactured by resin molding or the like. At the time of manufacturing, as shown in FIGS. 3A and 3B, the spout 19 of the cap body 11 is inserted through a thin weakened line portion 20. The inner plug 21 is integrally connected. The weakened line portion 20 is formed over the entire circumference of the inner periphery of the tip of the spout 19, and the bottle 1 is sealed by the weakened line portion 20 and the inner plug 21 when the hinge cap 10 is attached to the bottle 1. Thus, the contents in the bottle 1 are prevented from leaking.

  Further, as shown in FIGS. 4A and 4B, a spacer 25 is disposed so as to be positioned between the cap body 11 and the upper lid 13 with the cap body 11 covered with the upper lid 13. ing. As shown in FIGS. 1 to 5 and the like (details will be described later), the spacer 25 is connected to the upper lid 13 (or the cap body 11) via a thin part (thin weakening line part) 24 and is separable. Yes. In this embodiment, the spacer 25 is connected to the opening side edge of the upper lid 13 in an integrated state via a thin part (thin weakened line part) 24. Further, the inner surface of the upper lid 13 corresponding to the thin portion (thin weakened line portion) 24 is formed to be recessed, but the outer surface of the upper lid 13 is formed to be recessed to form the thin portion (thin weakened line portion) 24. Alternatively, the thin portion (thin weakened line portion) 24 may be configured by forming the outer surface and the inner surface of the upper lid 13 to be recessed.

  Here, as shown in FIGS. 4A and 4B, the spacer 25 has the hinge 12 at the right end (or left end) of the hinge cap 10 in a state where the upper lid 13 is put on the cap body 11. When viewed from the side so as to be in a positioned posture, it is formed into a shape that is a flat, substantially triangular shape (triangle, fan shape, etc.) with the side on which the hinge 12 is provided as the top. That is, in this embodiment, as viewed from the side, the thin portion (thin weakened line portion) 24 is inclined so as to be downward toward the hinge 12 side (inclined toward the location where the hinge 12 is provided). To be formed. Further, tabs (gripping portions) 26 extending downward are formed at both ends in the circumferential direction of the spacer 25, and the spacer 25 can be broken by gripping the tabs 26. Further, when the upper lid 13 is put on the cap body 11, a recess 27 that can accommodate the tab 26 is formed in a part of the skirt wall 14 of the cap body 11 so as to correspond to the tab 26.

  An upper lid coupling portion 22 that can be coupled to the inner plug 21 is integrally provided inside the upper lid 13, specifically, inside the top surface portion 13 a of the upper lid body that is the main body portion of the upper lid 13. In this embodiment, as shown in FIG. 3C and the like, the upper lid coupling portion 22 is composed of an inner cylinder coupling portion (functioning as a cylindrical portion) 22a and an outer cylinder coupling portion 22b. A coupling protrusion 22c that protrudes to the outer peripheral side is integrally formed on the entire periphery at the tip of the portion 22a. Correspondingly, as shown in FIG. 3B and the like, a coupling protrusion 21a is integrally formed on the entire inner periphery of the upper edge portion of the inner plug 21 as well. As will be described in detail later, as shown in FIGS. 6B and 6C, the coupling projection 21a of the inner plug 21 engages with the coupling projection 22c of the inner cylinder coupling portion 22a, and the inner plug 21 is engaged. Is configured to be coupled to the upper lid coupling portion 22. In this embodiment, the upper lid coupling portion 22 (the inner cylinder coupling portion 22a and the outer cylinder coupling portion 22b) has a shape that protrudes inward in a posture orthogonal to the surface of the top surface portion 13a of the upper lid body. Yes.

  In the above configuration, as shown in FIGS. 1 to 3, when the hinge cap 10 is commercialized by resin molding or the like, the hinge cap 10 is inserted into the spout 19 of the cap body 11 through the thin weakened line portion 20. The plug 21 is connected integrally. Therefore, as shown in FIG. 4, the hinge cap 10 is attached to the bottle 1 in which the contents are put in the state where the cap body 11 is covered with the upper lid 13. In this state, the bottle 1 is sealed. Thus, the contents in the bottle 1 will not leak.

  When opening, first, the tab 26 is grasped and spread to the outer peripheral side of the hinge cap 10, and as shown in FIG. 5, the spacer 25 is broken from the thin portion (thin weakened line portion) 24, Separate from the top lid 13. Thereafter, as shown in FIG. 6, the upper lid 13 is pushed down. As a result, the upper lid 13 can be favorably pushed downward by an amount corresponding to the space in which the spacer 25 is disposed with the hinge 12 as the center. First, the upper edge portion where the coupling protrusion 21 a of the inner plug 21 is provided is fitted between the inner cylinder coupling portion 22 a and the outer cylinder coupling portion 22 b of the upper lid coupling portion 22. The protrusion 21 a engages with the coupling protrusion 22 c of the inner cylinder coupling portion 22 a, and the inner plug 21 is firmly coupled to the upper lid coupling portion 22.

  In this case, when the shape of the spacer 25 is viewed from the side, the hinge 12 is formed in a state where the spacer 25 is separated by forming the spacer 25 into a substantially triangular shape with the side on which the hinge 12 is provided as a top. As a center, the upper lid 13 can be pushed downward favorably. Thereby, the inner plug 21 can be firmly coupled by the upper lid coupling portion 22 of the upper lid 13.

  Thereafter, as shown in FIG. 7, when the upper lid 13 is opened, the inner plug 21 is firmly coupled by the upper lid coupling portion 22 of the upper lid 13, so that the thin wall that connects the inner plug 21 and the cap body 11 is connected. The weakened wire portion 20 is broken, and the inner plug 21 is separated from the cap body 11 and attached to the back surface of the upper lid 13.

  As described above, according to the above configuration, only the separating operation from the upper lid 13 of the spacer 25 and the pressing operation of the upper lid 13 are performed, and then the inner lid 21 is easily separated from the cap body 11 by opening the upper lid 13. it can. Therefore, at the time of opening, there is no need to rotate the opening lid or main body cap and cut the weakened wire part with a cutting blade or blade (guide tube) as before, and the opening operation can be performed with less effort and time. It can be carried out. Moreover, even a person who is difficult to exert a great force such as an elderly person can perform the opening operation without any trouble, and convenience is improved.

  In the above embodiment, when the upper lid 13 is pushed in, the inner plug 21 is fitted in a state of being sandwiched between the inner cylinder coupling portion 22a and the outer cylinder coupling portion 22b. Although the coupling protrusion 21a is engaged with the coupling protrusion 22c provided on the inner cylinder coupling portion 22a as a cylindrical portion, the inner plug 21 is satisfactorily coupled to the upper lid coupling portion 22. Instead of this, a coupling protrusion is formed on the outer cylinder coupling part 22b, or a coupling protrusion is formed on both the inner cylinder coupling part 22a and the outer cylinder coupling part 22b so that the inner plug 21 is coupled to the upper lid 13. It may be configured.

  Further, according to the above configuration, since the tabs 26 that can be gripped are formed on the spacers 25, the spacers 25 can be easily removed by holding the tabs 26 when opened, and good convenience can be maintained. it can.

  In the above embodiment, the case where the upper lid coupling portion 22 (the inner cylinder coupling portion 22a and the outer cylinder coupling portion 22b) protrudes inward in a posture orthogonal to the surface of the top surface portion 13a of the upper lid body. As stated, this is not a limitation. That is, according to this configuration, as shown in FIGS. 6A and 6B, when the upper lid 13 is closed on the cap body 11 after the spacer 25 is removed, the upper lid 13 is slightly inclined because the spacer 25 is not present. It is put on with the posture. Therefore, together with the top surface portion 13a of the upper lid main body (the main body portion of the upper lid 13), the inner plug 21 comes into contact with the spout 19 of the cap main body 11 in a slightly inclined posture. Therefore, even when the upper lid 13 is closed, the bottle 1 with the hinge cap 10 is vigorously shaken. In some cases, the contents may leak to the outside with the upper lid closed.

  8 to 10 show a hinge cap 10 according to another embodiment for improving such a problem. In the hinge cap 10, the upper lid coupling portion 22 is formed so that the inner plug 21 is attached in a horizontal posture with respect to the upper lid 13 that is inclined and closed with the spacer 25 removed. In this embodiment, the surface of the top surface portion 13a of the upper lid body on which the upper lid coupling portion 22 is formed (upper lid coupling portion forming surface 22d) is closed with the upper lid 13 tilted and closed with the spacer 25 removed. At this time, it is formed so as to be substantially horizontal, and an inner cylinder coupling portion 22e and a coupling projection 22f for locking the inner plug 21 are formed from the upper lid coupling portion forming surface 22d. When the spacer 25 is removed and the upper lid 13 is closed, the coupling projection 21a of the inner plug 21 is coupled to the coupling projection of the upper lid coupling portion 22 in a state where the upper edge portion of the inner plug 21 is in contact with the upper lid coupling portion forming surface 22d. 22f and the inner cylinder coupling portion 22e are engaged, whereby the inner plug 21 comes into contact with the spout 19 of the cap body 11 in a horizontal posture.

  As a result, even when the spacer 25 is removed and the upper lid 13 is tilted and closed, the inner plug 21 comes into close contact with the spout 19 of the cap body 11 in a good horizontal position, and the upper lid 13 is In the closed state, the contents can be well prevented from leaking to the outside, and the reliability is improved.

  In the above embodiment, the case where the spacer 25 is connected to the opening side edge of the upper lid 13 via the thin weakened line portion 20 has been described. Instead, the spacer 25 having the same shape is used. May be formed above the skirt wall 14 of the cap body 11 via a thin weakened line portion. In this case, the same effect can be obtained by separating the spacer 25 from the skirt wall 14 of the cap body 11. .
