Description

The present invention relates to a hinge cap in which an upper lid is provided on the main body via a hinge.

As a cap attached to the container, a hinge cap having a main body attached to the mouth of the container and an upper lid provided on the main body via a hinge is widely known. Further, in this type of hinge cap, the main body is provided with a partition wall arranged so as to close the mouth of the container and a breakable thin-walled portion formed on the partition wall, which is also called a score. A hinge cap that can be opened to open the contents by breaking it is also already known.

Many of such hinge caps have an operating portion called a pull ring integrally formed on the partition wall. Then, by pulling up the pull ring (operating portion) with the upper lid open, the thin-walled portion is broken and opened (for example, Patent Document 1 and the like).

However, the hinge cap having a structure in which the pull ring is pulled up to open in this way may cause various problems as described below. For example, there may be a problem that it is difficult to catch a finger on the pull ring at the time of opening, or the resistance when pulling up the pull ring is large and the finger may hurt. In addition, the base of the support column of the operation portion connected to the pull ring and the connection portion between the support column and the pull ring may be broken, and in this case, the thin-walled portion cannot be broken.

In order to deal with such a problem, in Patent Document 2 and the like, the partition wall provided on the main body is pushed directly with a finger, or the support column erected on the partition wall is pushed with a finger without providing a pull ring. The structure is disclosed. According to this structure, since there is no pull ring itself, the above-mentioned problem related to the pull ring can be solved.

Japanese Unexamined Patent Publication No. 2002-154570 Japanese Patent No. 4466816

However, as disclosed in Patent Document 2, according to the structure in which the partition wall provided on the main body is directly pushed by a finger, or the support column erected on the partition wall is pushed by a finger, the partition wall is directly pushed. When pushing with a finger or pushing a support column erected on a partition wall with a finger, the contents in the container may adhere to the finger. In addition, the partition wall or support column pushed in with a finger enters the container, and the contents come into direct contact with the pushed partition wall or support column, which may result in unsanitary conditions.

The present invention solves the above-mentioned problems, and it is not necessary to provide a pull ring, and the contents in the container adhere to the finger, or the contents come into direct contact with the partition wall or the support column pushed by the finger, which is unsanitary. The purpose is to provide a hinge cap that does not become.

In order to solve the above problems, the present invention has a main body attached to the mouth of the container and an upper lid provided on the main body via a hinge, and the main body closes the mouth of the container. A hinge cap in which a partition wall arranged in a container and a breakable thin-walled portion formed in the partition wall are provided, and an opening for ejecting the contents in the container is formed by breaking the thin-walled portion. , A deformable pressing portion is provided on the partition side of the main body, and by pressing the pressing portion of the upper lid, the pushing portion inside the thin-walled portion is pushed into the inner side of the container and opened while the thin-walled portion is broken. It is characterized by that.

In this configuration, when the container is opened, the upper lid is covered with the main body and the pressing portion of the upper lid is pressed with a finger or the like in a closed state, so that the thin-walled portion is broken and the inner pushing portion of the thin-walled portion for breaking is the container. It can be pushed inward to open it. That is, according to this configuration, it is not necessary to provide a pull ring, and since a finger or the like is not directly pushed into the container, the contents in the container may adhere to the finger or the part of the partition wall pushed by the finger. The contents do not come into direct contact with the or columns and become unsanitary.

Further, in the present invention, the pushing portion is formed with a pressing pressure transmitting projection capable of contacting the back surface of the pressing portion of the upper lid, and when the pressing portion of the upper lid is pressed, the pushing portion is formed via the pressing pressure transmitting projection. It is characterized by being pushed in.

According to this configuration, when the pressing portion of the upper lid is pressed with a finger or the like at the time of opening, this pressing pressure is transmitted to the entire pressing portion via the pressing pressure transmitting protrusion formed on the pressing portion of the main body, and the thickness is thin. The pushed part can be pushed in while breaking the part well.

Further, in the present invention, the partition wall is provided with a deformed fulcrum that is deformed to become a fulcrum when the pushing portion of the main body is pushed through the pressing portion of the upper lid, and is pushed when the pressing portion of the upper lid is pressed. The pressure transmitting protrusion is characterized in that the pushing portion is pushed while being deformed with the contact point with the pressing portion of the upper lid as the action point and the deformation fulcrum as the fulcrum.

According to this configuration, the so-called "lever principle" having an action point and a fulcrum can be used to deform the push-in deformation portion or break the breaking thin-walled portion, and the pressing force at this time can be further increased. It is possible to do with a small force.

Further, as the deformation fulcrum, it is preferable that the first deformation fulcrum provided in the uncut portion of the thin wall portion and the second deformation fulcrum provided in the vicinity of the pressing force transmission protrusion in the partition wall are provided. ..

Further, the present invention is characterized in that the main body is provided with a protrusion locking portion that locks the pushing pressure transmitting protrusion in a state of being opened when the pushing portion is pushed. With this configuration, once the push-in portion is deformed or the thin-walled portion is broken to open the opening, this open state can be maintained satisfactorily.

Further, the present invention is characterized in that the upper lid is provided with an operation notch portion into which a finger can be inserted when pressing the pressing portion. According to this configuration, the pressing portion can be pressed while inserting a finger or the like into the notch for operation, which is convenient.

According to the present invention, the upper lid is provided with a deformable pressing portion on the partition side of the main body, and when the pressing portion of the upper lid is pressed, the thin-walled portion is broken and the pushed portion inside the thin-walled portion is inside the container. By configuring the container so that it is pushed to the side and opened, it is not necessary to provide a pull ring, and the container can be opened without a finger or the like being pushed directly into the container, so that the contents inside the container can be opened. It is possible to satisfactorily prevent the contents from adhering to the finger or the contents directly coming into contact with the partition wall or the support column pushed by the finger, resulting in unsanitary conditions.

Further, a pressing force transmitting protrusion that can come into contact with the back surface of the pressing portion of the upper lid is formed in the pushing portion so that when the pressing portion of the upper lid is pressed, the pushing portion is pushed through the pressing pressure transmitting projection. With the configuration, the pushed-in portion can be satisfactorily deformed and the thin-walled portion can be satisfactorily broken.

Further, the partition wall is provided with a deformed fulcrum that is deformed to serve as a fulcrum when the pushing portion of the main body is pushed through the pressing portion of the upper lid, and when the pressing portion of the upper lid is pressed, the upper lid in the pressing pressure transmission protrusion. The so-called "lever principle" having an action point and a fulcrum is established by configuring the pushing portion to be pushed while deforming while the contact point with the pressing portion is the action point and the deformation fulcrum is the fulcrum. By using it, the pushing portion can be easily deformed or the thin-walled portion can be broken with a small force.

Further, if the first deformation fulcrum provided in the uncut portion of the thin-walled portion and the second deformation fulcrum provided in the vicinity of the pressing force transmission protrusion in the partition wall are provided as the deformation fulcrum, there are two. While using the deformation fulcrum, the pushed portion can be deformed or the thin portion can be broken even better.

Further, by providing the main body with a protrusion locking portion that locks the pushing pressure transmission protrusion in an open state when the pushing portion is pushed in, the pushing portion is once deformed or the thin-walled portion is broken. When the opening is performed, this open state can be maintained satisfactorily and labor can be saved.

Further, by providing the upper lid with an operation notch into which a finger can be inserted when pressing the pressing portion, the pressing portion can be pressed while inserting a finger or the like into the operation notch, which is convenient. ..

Hereinafter, the hinge cap according to the embodiment of the present invention will be described with reference to the drawings.
Here, FIGS. 1 to 8 show hinge caps according to an embodiment of the present invention (first embodiment), respectively. Further, in these figures, FIGS. 1 and 2 show a state before opening with the top lid closed, and FIGS. 3 to 5 show a state before opening with the top lid opened (state at the time of manufacturing), and FIGS. FIG. 7 shows the state at the time of opening in stages (time).

In FIGS. 1 to 5 and the like, reference numeral 1 denotes a hinge cap attached to a container 2 in which a content (content liquid) is housed. The hinge cap 1 has a main body (cap main body) 4 attached to the mouth 3 of the container 2 and an upper lid 6 provided on the main body 4 via the hinge 5. The main body 4 does not necessarily have to be directly attached to the mouth 3 of the container 2. For example, the main body 4 is indirectly attached to the mouth 3 of the container 2 via an inner plug or the like. There may be. The hinge cap 1 is made of, for example, a synthetic resin, and in this case, the hinge cap 1 is integrally formed by injection molding produced by injecting a molten synthetic resin into a mold. The relatively thin portion of the hinge cap 1 is elastically deformable.

The main body 4 has a top surface 11 arranged so as to face the upper end surface of the mouth portion 3 of the container 2 from above, and a lower portion extending downward from the outer periphery of the top surface 11 from the outside to the mouth portion 3 of the container 2. The cylindrical outer cylinder 12 to be fitted is formed so as to extend downward from the top surface 11 at a position having a radial gap at the inner peripheral position of the outer cylinder 12, and the lower portion thereof is formed from the inside into the mouth 3 of the container 2. The cylindrical inner cylinder 13 to be fitted, the locking cylinder 17 extending in an annular shape upward from the outer peripheral portion of the top surface 11, and the locking cylinder 17 protruding upward and downward from the outer peripheral portion of the top surface 11, respectively, in the container 2. A discharge cylinder 14 for pouring out the contents, and a partition wall 15 formed inside the inner cylinder 13 and the dispenser cylinder 14 to close the mouth portion 3 (inner side region and outer side region of the hinge cap 1) of the container 2. And the breakable thin-walled portion (also referred to as a score) 16 formed in the partition wall 15, and the contents in the container 2 formed inside (center side in a plan view) of the thin-walled portion 16 in the partition wall 15. A push-in portion (scheduled opening portion) 18 or the like for forming an opening for forming an opening is provided.

In this embodiment, as shown in FIGS. 3 and 4, the dispensing cylinder 14 has a large upward protrusion on the side away from the hinge 5, while the upward protrusion dimension increases as the hinge 5 approaches. It is inclined so as to be gradually reduced, and is formed so that the upward protrusion dimension is the smallest at a position close to the hinge 5.

When the hinge cap 1 is attached to the container 2, the hinge cap 1 is placed on the mouth 3 of the container 2 with the upper lid 6 closed (the main body 4 is covered with the upper lid 6), and the hinge cap 1 is struck from above. When the hinge cap 1 is plugged by the stopper, the mouth portion 3 of the container 2 is sandwiched and fitted between the outer cylinder 12 and the inner cylinder 13 of the main body 4, and the hinge cap 1 is attached to the container 2. Will be done.

The upper lid 6 is provided with a lid plate 22 provided near the outer circumference on the upper surface, and an outer peripheral surface (also referred to as a skirt) 21 continuous with the lid plate 22. Specifically, when the upper lid 6 is closed, the lower edge of the upper lid 6 comes into contact with the upper edge of the outer peripheral portion of the outer cylinder 12 of the main body 4, and the locking cylinder 17 of the main body 4 is brought into close contact with the outer peripheral surface from the inside. 21 and the lid plate 22 that is gently connected to the upper end edge of the outer peripheral surface 21 and the lid plate 22 that protrudes downward in an annular shape from the inner portion of the lid plate 22 and seals the pouring cylinder 14 closely from the inside when the upper lid 6 is closed. An inner ring (also referred to as an inner peripheral protrusion) 23 or the like is provided.

In addition to the above configuration, the upper lid 6 is provided with a deformable pressing portion 24 (that is, deformable downward with the upper lid 6 closed) on the partition wall 15 side of the main body 4. In this embodiment, the pressing portion 24 is provided so as to extend from the lower end portion of the inner ring 23 toward the center side and cover the central side region in a plan view. As shown in FIGS. 1 to 5, the shape of the pressing portion 24 before opening is roughly such that the outer peripheral portion is connected to the lower end portion of the inner ring 23 and is recessed downward, while the center. The shape is such that the partial region bulges upward and the central portion in the central region bulges slightly downward, but the shape is not limited to this.

Then, when the pressing portion 24 of the upper lid 6 is pressed downward (to the side where the partition wall 15 of the main body 4 is provided) while the upper lid 6 is closed before opening, the thin-walled portion 16 (specifically, the thin-walled portion 16) is pressed. While the breaking thin-walled portion 16a), which is a part of the portion 16 and will be described later, is broken, the pushing portion 18 provided inside the thin-walled portion 16 is pushed into the inner side (that is, downward) of the container 2 to be opened. It has become so.

Here, as shown in FIG. 5, the thin-walled portion 16 is provided on the inner side of the partition wall 15 from the connection portion with the inner cylinder 13 in a plan view, and is provided in a substantially circular shape in this embodiment. On the surface, as shown in FIG. 1 and the like, the partition wall 15 is provided at a portion extending diagonally downward toward the inside of the connecting portion with the inner cylinder 13. Further, the push-in portion 18 provided inside the thin-walled portion 16 in the partition wall 15 of the main body 4 is formed with a push-pressure transmission protrusion 18a capable of contacting the back surface of the push-in portion 24 of the upper lid 6. Then, the side of the thin-walled portion 16 near the pressing force transmitting projection 18a (specifically, a portion other than the end portion on the side away from the pressing force transmitting projection 18a) breaks when the pressing force transmitting projection 18a is pushed. While the thin-walled portion 16a for breaking is used, the end portion of the thin-walled portion 16 on the side away from the pressing force transmission projection 18a does not break when the pressing portion 24 of the upper lid 6 is pressed. It is a thin-walled portion 16b for a fulcrum as a first deformation fulcrum that is deformed as a fulcrum.

That is, the partition wall 15 is provided with a deformed fulcrum that is deformed to serve as a fulcrum when the pushing portion 18 of the main body 4 is pushed through the pressing portion 24 of the upper lid 6. More specifically, in this embodiment, two deformation fulcrums that are deformed to serve as fulcrums when the pushing portion 18 of the main body 4 is pushed in are provided, and as shown in FIG. 6, the first deformation As a fulcrum, it is provided in the fulcrum thin-walled portion 16b away from the pressing force transmission projection 18a in the thin-walled portion 16 provided in the partition wall 15. Further, a second deformation fulcrum 18b, which is deformed slightly later than this and becomes a fulcrum, is provided at a position near the center of the main body at the lower end of the push pressure transmission protrusion 18a in the push portion 18. In this embodiment, the breaking thin-walled portion 16a and the pressing force transmitting projection 18a are arranged on the side closer to the hinge 5, and the fulcrum thin-walled portion 16b is arranged on the side away from the hinge 5.

Further, the main body 4 is provided with a protrusion locking portion 32 that locks the pushing pressure transmission protrusion 18a in a state of being opened when the pushing portion 18 is pushed in and holds the opened state. In this embodiment, the protrusion locking portion 32 is a portion of the partition wall 15 that inclines diagonally downward from the inside of the inner cylinder 13 near the hinge 5 (a push that first breaks in the thin portion 16 when the push portion 18 is pushed in). It is provided in a portion following the thin-walled portion 16a for breaking near the pressure transmission protrusion 18a).

Further, as shown in FIGS. 1, 2, 2, 4 and the like, the upper lid 6 is provided with an operation notch 31 into which a finger can be inserted when pressing the pressing portion 24 so as to be recessed downward from the lid plate 22. ing. Then, when the pressing portion 24 is pushed in, a finger is inserted into the notch portion 31 for operation, so that the pushing operation of the pressing portion 24 can be easily performed. In this embodiment, the operating notch 31 is provided on the upper lid 6 near the hinge 5, that is, near the portion of the main body 4 where the pressing force transmitting protrusion 18a is provided.

Further, in this embodiment, as shown in FIGS. 2, 4, 5, and the like, the outer peripheral surface 21 of the upper lid 6 which is substantially circular in plan view is recessed into a substantially flat shape in plan view. The recessed portions 33 are formed at two locations on the left and right. Then, when the upper lid 6 is opened, the upper lid 6 is pinched so as to sandwich the upper lid 6 from the left and right using the recessed portion 33 for operation, so that the upper lid 6 is slightly deformed and easily disengaged from the locking cylinder 17, making the upper lid 6 easier. It is designed so that it can be opened. In this embodiment, the operating recess 33 is formed with fine irregularities so that the fingers do not slip easily and the operation is easy, but the present invention is not limited to this. Further, in this embodiment, since the upper lid 6 can be opened by using the operating recess 33, the upper lid 6 is located on the outer peripheral surface of the upper lid 6 at a position away from the hinge 5 (so-called front end portion on the outer peripheral surface of the upper lid 6). There is no collar for opening 6.

In the above configuration, when the container (commodity) 2 containing the contents of the hinge cap 1 is shipped, as shown in FIGS. 1 and 2, the partition wall 15 of the main body 4 is unopened. The upper lid 6 is attached to the container 2 in a closed state. Therefore, when the container 2 to which the hinge cap 1 is attached is used, the opening operation as shown in FIGS. 6 and 7 is performed.

That is, the pressing portion 24 of the upper lid 6 is pushed down by inserting a finger into the notch 31 for operation, and the pressing portion 24 of the upper lid 6 is pushed to open the partition wall 15 of the main body 4. At this time, when the pressing force transmitting protrusion 18a is pushed into the inner side (that is, downward) of the container 2 through the pressing portion 24 of the upper lid 6, that is, the contact with the pressing portion 24 of the upper lid 6 in the pressing force transmitting projection 18a. The contact point serves as the point of action, and as shown in FIGS. 6 and 7, the entire pushing portion 18 is on the inner side (that is, downward) of the container 2 with the thin-walled portion 16b for the fulcrum as the first deformation fulcrum as the center (fulcrum). Also, with the second deformation fulcrum 18b as the center (fulcrum), the tip of the pressing force transmission protrusion 18a is deformed so as to be tilted toward the center of the main body in a plan view. Thereby, by using the so-called "lever principle" having an action point and a fulcrum, it is possible to easily deform the pushing portion 18 or break the thin-walled portion 16a for breaking the thin-walled portion 16 with a small force. An opening 34 is formed in the inner portion of the thin wall portion 16 in the partition wall 15.

Further, since the partition wall 15 of the main body 4 is provided with the protrusion locking portion 32, once the pushing portion 18 is pushed through the pressing portion 24 of the upper lid 6, the protrusion locking portion is locked even if the finger is released from the upper lid 6. The pressing force transmitting projection 18a is locked by the portion 32 in a well-opened state. Therefore, after that, as shown in FIG. 8, by tilting the container 2 with the upper lid 6 open, the contents in the container 2 can be satisfactorily poured out.

Further, according to the above configuration, since the pull ring is not provided, there is a problem that it is difficult to catch a finger on the pull ring at the time of opening, the resistance when pulling up the pull ring is large and the finger hurts, or the finger is connected to the pull ring. It is possible to prevent various problems caused by the pull ring, such as the root of the support column of the operating portion and the connection portion between the support column and the pull ring being broken so that the thin portion cannot be broken.

Further, according to the above configuration, the upper lid 6 is provided with a deformable pressing portion 24 on the partition wall 15 side of the main body 4, and by pressing the pressing portion 24, the thin-walled portion 16a for breaking the partition wall 15 of the main body 4 is formed. Since the container is broken and opened, the container can be opened without a finger or the like being directly pushed into the container 2. As a result, it is possible to satisfactorily prevent the contents in the container 2 from adhering to the fingers or the contents from directly contacting the portion of the partition wall 15 pushed by the fingers to become unsanitary, which is convenient. Good hygiene can be maintained.

Further, in the above configuration, since the pushing portion 18 is opened in a state of being pushed into the container 2, when the contents are poured out, the contents are opened in a gap between the pushing portion 18 and the opening 32. It is thought that there will be an effect of being poured out while being rectified due to collision.

Further, according to the above configuration, since the upper lid 6 is provided with an operation notch 31 into which a finger can be inserted when pressing the pressing portion 24, the pressing portion while inserting a finger or the like into the operation notch 31 is provided. It is convenient to be able to press 24.

Further, in the above configuration, on the outer peripheral surface 21 of the upper lid 6, operation recesses 33 that are recessed in a substantially flat shape in a plan view are formed at two positions on the left and right, and are used for this operation when the upper lid 6 is opened. The upper lid 6 can be easily opened by pinching the upper lid 6 from the left and right using the recessed portion 33. As a result, since the upper lid 6 is not provided with a collar for opening the upper lid 6, if a collar is provided, an object or a finger may be caught by the collar when the lid is laid on its side after opening. There is an advantage that the problem that the upper lid 6 is opened and the contents leak out does not occur.

In the above embodiment, the pressing force transmission protrusion 18a, the thin wall portion 16a for breaking, and the protrusion locking portion 32 are provided on the side of the partition wall 15 near the hinge 5, and the thin wall portion for the fulcrum as the first deformation fulcrum is provided. The case where the 16b is provided on the side of the partition wall 15 away from the hinge 5 has been described. However, the present invention is not limited to this configuration, and depending on the size of the hinge cap 1 and its use, as shown in FIGS. 9 to 13, the pressing force transmission protrusion 18a, the thin-walled portion 16a for breaking, and the protrusion locking portion 32 are used. May be provided on the side of the partition wall 15 away from the hinge 5, and the fulcrum thin-walled portion 16b as the first deformation fulcrum may be provided on the side of the partition wall 15 near the hinge 5.

That is, even with this configuration, when the package is opened, as shown in FIGS. 14 and 15, the pressing pressure transmitting protrusion 18a is pushed through the pressing portion 24 of the upper lid 6 to serve as a fulcrum as the first deformation fulcrum. Using the so-called "lever principle" with the thin-walled portion 16b and the second deformation fulcrum 18b as the center (fulcrum) and having an action point and a fulcrum, the thin-walled portion 16a for breaking the thin-walled portion 16 can be easily broken with a small force. The pushing portion 18 can be deformed, and the opening 34 can be satisfactorily formed in the inner portion of the thin-walled portion 16 in the partition wall 15. Therefore, after that, as shown in FIG. 16, by tilting the container 2 with the upper lid 6 open, the contents in the container 2 can be satisfactorily poured out, and the same operation as that of the above-described embodiment can be obtained. The effect can be obtained.

Further, in the above embodiment, the case where the upper lid 6 is not provided with a collar for opening the upper lid 6 is not limited to this, and as shown in FIGS. 9 to 16, the upper lid 6 is not provided. A collar 35 for opening the upper lid 6 may be provided in 6.
