Description

The present invention relates to caps and containers that are attached to containers.

Conventional screw-type caps attached to containers such as PET bottles for beverages require the use of both hands to open, so even people with disabilities, the elderly, and healthy people can use them with one hand. In some cases, the bottle could not be easily opened when someone was holding something. In contrast, non-threaded caps have been proposed.

For example, in Patent Document 1, a film-like lid material for closing a container opening is opened by pushing a cap body equipped with a piercing tool with a finger, and the lid material is further opened by sliding the pushed cap body. A cap that can be opened wide is disclosed. Further, in Patent Document 2, a slide member having a projection on the bottom surface is provided on the top surface of the opening piece on which the hinge portion is left and the score line is provided, and by sliding the slide member, the projection pushes down the opening piece to open the opening Disclosed is a can lid that allows for

The cap described in Patent Literature 1 requires a two-step operation of pushing down and sliding, and it takes time and effort to open the container. Since the slide member described in Patent Document 2 has a small downward stroke of the projection, when applied to a container closed with a film-like lid material, the lid material may not be broken.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cap and a container having the cap that can be reliably opened by easy operation even in a situation where only one hand can be used, for example.

A first aspect of the present invention is
A cap attached to the opening of a container sealed with a breakable film member,
a tubular cap main body having a pouring part for pouring out the contents in the upper part and a mounting part to be mounted in the opening part in the lower part;
a lid member provided on the top of the cap body and configured to be slidable from a first position for closing the spouting portion to a second position for opening the spouting portion with respect to the cap body;
a blade member connected via a hinge from the tip of a support portion extending in the radial direction from the inner surface of the cap body;
with
The blade member has a blade for breaking the film member formed on the lower surface opposite to the hinge portion, and is configured to tilt downward toward the film member by bending the hinge portion,
The lid member has a protrusion that protrudes toward the upper surface of the blade member,
When the lid member slides from the first position to the second position, the protrusion contacts the upper surface of the blade member and pushes down the blade member, whereby the blade of the blade member breaks the film member. A cap configured to.

According to the cap of the first aspect, when the cover member is slid from the first position to the second position, the protrusion of the cover member presses down the blade member while sliding in contact with the upper surface of the blade member, The blade member tilts downward toward the film member due to bending of the hinge portion. Thereby, the blade formed on the lower surface of the blade member breaks the film member. Therefore, the user can open the container sealed with the film member by a simple one-handed operation of sliding the lid member from the first position to the second position.

A second aspect of the present invention is
A cap to be attached to the opening of the container, comprising:
a tubular cap main body having a pouring part for pouring out the contents in the upper part and a mounting part to be mounted in the opening part in the lower part;
a lid member provided on the top of the cap body and configured to be slidable from a first position for closing the spouting portion to a second position for opening the spouting portion with respect to the cap body;
a blade member connected via a hinge from the tip of a support portion extending in the radial direction from the inner surface of the cap body;
with
The cap body is sealed with a breakable film member at the lower portion of the blade member,
The blade member has a blade for breaking the film member formed on the lower surface opposite to the hinge portion, and is configured to tilt downward toward the film member by bending the hinge portion,
The lid member has a protrusion that protrudes toward the upper surface of the blade member,
When the lid member slides from the first position to the second position, the protrusion contacts the upper surface of the blade member and pushes down the blade member, whereby the blade of the blade member breaks the film member. A cap configured to.

The cap according to the first aspect of the present invention can obtain the above-described specific effects by being attached to a container whose opening is sealed by a film member. Since the inside of the cap body is sealed by the film member, the cap of the aspect of the above can similarly obtain the above-mentioned specific effects by attaching it to a container whose opening is not sealed.

In the present invention, the protrusion is positioned on the blade side of the blade member at a first position where the lid member closes the pouring portion, and at a second position where the lid member opens the pouring portion. It may be configured to be positioned on the hinge portion side of the blade member.

According to this configuration, at the first position, the protrusion is located on the blade side of the blade member in the sliding direction, and at the second position, the protrusion is located on the hinge side of the blade member in the sliding direction, and the lid member is closed. When slidably moved from the first position to the second position, the protrusion slides on the upper surface of the blade member from near the blade toward the hinge while being in contact with the blade member. The blade member tilts downward so as to rotate about the hinge portion. The distance between the position where the protrusion pushes the upper surface of the blade member (the position in contact with the upper surface) and the hinge, which is the center of rotation, becomes shorter as the protrusion approaches the hinge. If the projection pushes the upper surface of the blade member downward by the same amount, the shorter the distance between the position where the projection pushes the upper surface of the blade member and the center of rotation, the greater the rotation angle of the blade member. The downward travel of the blade at the end of the blade member opposite the hinge portion is increased. Therefore, as the protrusion approaches the hinge, the blade of the blade member breaks the film member with a large stroke, and the film member is largely unsealed by the rotational motion. Accordingly, the user can more reliably open the container sealed with the film member by a simple one-handed operation of sliding the lid member from the first position to the second position.

In the present invention, the lid member is movable obliquely downward with respect to the upper surface of the blade member,
The protrusion may be configured to approach the upper surface of the blade member as the lid member approaches the second position from the first position.

According to this configuration, since the upper surface of the blade member and the direction of sliding movement of the lid member are not parallel but form an angle, the lid member is fixed to the lid member as it approaches the second position from the first position. The vertical distance between the protrusion and the upper surface of the blade member becomes shorter, and after the protrusion contacts the upper surface of the blade member, the protrusion and the upper surface of the blade member at the initial position before starting to rotate The vertical distance (the amount by which the blade member is pushed downward) increases. Therefore, as the protrusion approaches the hinge, the blade of the blade member breaks the film member with a large stroke, and the film member is largely unsealed by the rotational motion. The user can more reliably open the container sealed with the film member by a simple one-handed operation of sliding the lid member downward obliquely.

In the present invention, the lid member is movable parallel to the upper surface of the blade member,
The upper surface of the blade member includes an inclined surface extending from the blade side toward the hinge portion side,
The protrusion may be configured to approach the inclined surface of the blade member as the lid member approaches the second position from the first position.

According to this configuration, the user can more reliably open the container sealed with the film member by a simple one-handed operation of horizontally sliding the lid member.

In the present invention, the lid member moved from the first position to the second position is movable from the second position to the first position,
The cap main body and the lid member may have engaging portions that engage with each other at the first position.

According to this configuration, the lid member is configured to be reciprocally movable between the first position and the second position. The user can close the pouring part by a simple operation of sliding the lid member in the direction opposite to the opening. Furthermore, the cap body and the lid member are engaged at the first position. The engaging portion fixes the cap main body and the lid member with a certain locking force, and when an external force exceeding the locking force acts, the fixing between the cap main body and the lid member is released. Configured. In a free state in which the cap main body and the lid member are not fixed, the cap main body and the lid member are engaged by applying a predetermined force. This prevents the cover member from unintentionally moving from the first position to open the pouring part after returning to the first position for closing the pouring part.

In the present invention, the side surface of the mounting portion of the cap body on the sliding direction side of the lid member may be provided with a projecting portion on which a user's finger can be placed.

According to this configuration, when the user tries to slide the lid member from the first position to the second position, it is possible to prevent the lid member from holding a position that hinders the sliding.

The cap according to the present invention can be applied to a cap in which the attachment part is a screw-in type, and can also be applied to a cap in which the attachment part is a capping type, and the attachment part can be applied to:
It can also be applied to a cap having a flange portion fixed to the periphery of the opening of the container. Even if it is applied to any type of cap, it is possible to obtain the above-mentioned specific effects.

The present invention also includes a container in which a cap having each of the above configurations is attached to the opening.

ADVANTAGE OF THE INVENTION According to the present invention, it is possible to provide a cap and a container having a cap that can be reliably opened by an easy operation even in a situation where only one hand can be used, for example.

The cap main body 20 has a pouring portion 21 formed with an opening 213 for pouring out the contents contained in the container 2 at the top, and a mounting portion 22 mounted on the opening 40 of the container 2 at the bottom. It has a substantially cylindrical shape. The extraction part 21 has a pair of planar side surfaces 29 parallel to the sliding direction S, and the side surfaces 29 are provided with a plurality of bosses 28 . A sliding portion 31 of a lid member 30 to be described later is attached to the boss 28 . A projecting portion 23 is provided at the end of the mounting portion 22 in the sliding direction. The upper end portion of the extraction portion 21 is formed parallel to the slide direction S so as to obliquely descend from the end portion 214 on the first position side to the end portion 212 on the second position side. Examples of contents to be accommodated in the container 2 include liquids, powders, solids smaller than the opening area of the pouring part 21, and the like.

A slide hole 36 extending parallel to the slide direction S is provided in a side surface parallel to the slide direction S of the slide portion 31 . The width of the slide hole 36 in the direction perpendicular to the slide direction S is substantially equal to the diameter of the boss 28 of the mounting portion 22, and the slide portion 31 can be slid by the mounting portion 22 by engaging the slide hole 36 and the boss 28. supported by

The position of the cover member 30 when the boss 28 is at the first end 37 is called the "first position", and the position of the cover member 30 when the boss 28 is at the second end 38 is called the "second position". 2B and 2C show the lid member 30 in the first position.

2C is a perspective view showing a state where the cover portion 32 is attached to the slide portion 31. FIG. The pouring portion 21 of the cap body 20 is closed by the cover portion 32 when the lid member 30 is at the first position.

The slide portion 31 and the cover portion 32 of the lid member 30 are not limited to the separate structure as described above, and may be integrally structured. 3A and 3B are perspective views showing a cap having a lid member in which a slide portion and a cover portion are integrally constructed.

FIG. 3A shows a state in which the lid member 30A of the cap 1A is in the first position that closes the spout portion 21 of the cap body 20. FIG. The lid member 30A has a slide portion 31A and a cover portion 32A which are integrally constructed. The slide portion 31A is provided with a slide hole 36 similar to that described with reference to FIG. 2B, and the boss 28 of the cap body 20 is positioned at the first end portion 37 of the slide hole 36 in the state of FIG. 3A. The spout portion 21 of the cap body 20 is closed by the cover portion 32A.

FIG. 3B shows a state where the lid member 30A of the cap 1A is in the second position where the spout portion 21 of the cap body 20 is opened. The boss 28 of the cap body 20 is positioned at the second end 38 of the slide hole 36, and the cover member 30A slides to the second position, thereby partially exposing the opening 213 of the pouring part 21. The spout portion 21 of the cap body 20 is opened.

As shown in FIG. 3C, the first end 37 of the slide hole 36 in the slide direction and the second end 38 opposite the slide direction are angled with respect to the slide direction. That is, most of the longitudinal direction of the slide hole 36 is parallel to the slide direction and has an angle with respect to the horizontal direction. ) is provided.

FIG. 4 is a cross-sectional view of the cap 1 taken along line AA of FIG. AA cross section in FIG. 1 is a plane parallel to the sliding direction S and including the central axis of the opening 40 of the container 2 . FIG. 4 shows the lid member 30 in the first position.

A male thread 42 is provided on the outer peripheral surface of the opening 40 of the container 2, and a female thread 222 is provided on the inner peripheral surface of the attachment portion 22 of the cap 1, so that the cap 1 is attached to the container 2 by screwing. Note that the cap of the present invention is not limited to the screw-in type, and can be applied to caps of the capping type and welding type as described later (see FIGS. 9 to 11).

The lid member 30 is configured to be slidable in the obliquely downward sliding direction S with respect to the cap body 20 by the structure described with reference to FIGS. 2A to 2C, 3A, and 3B. Note that the sliding direction S is not limited to the oblique downward direction, and can be, for example, a horizontal direction as described later (see FIGS. 7 and 8).

When the lid member 30 is in the first position, the lower surface of the cover portion 32 of the lid member 30 and the upper end portion of the spout portion 21 of the cap body 20 are engaged at the engagement portion 34 . Specifically, the engaging portion 34 is configured such that the annular concave portion 321 provided on the lower surface of the cover portion 32 and the annular convex portion 211 provided on the upper end portion of the pouring portion 21 are engaged. . The engaging portion 34 is disengaged when a certain force is applied in the sliding direction S in a state where the annular recessed portion 321 and the excess convex portion 211 are engaged. That is, the engaging portion 34 fixes the pouring portion 21 of the cap body 20 and the cover portion 32 of the lid member 30 with a certain locking force. When a force exceeding this locking force is applied to the engaging portion 34, the fixation between the pouring portion 21 of the cap body 20 and the cover portion 32 of the lid member 30 is released. In a free state in which the spout portion 21 of the cap body 20 and the cover portion 32 of the lid member 30 are not fixed, applying a predetermined force brings the annular concave portion 321 and the excess convex portion 211 into a state of engagement.

The cap body 20 includes a blade member 27 connected via a hinge portion 24 to the tip of a support portion 25 extending radially inward from the inner surface 26 . A blade 271 for breaking the film member 41 provided at the upper end of the opening 40 of the container 2 is formed on the lower surface of the blade member 27 near the end opposite to the sliding direction with respect to the hinge portion 24 . . When the hinge portion 24 is bent, the blade member 27 tilts downward toward the film member 41 so as to rotate in the direction of arrow R about the hinge portion 24 . In this embodiment, the lid member 30 and the cap body 20 are made of resin. Further, the opening 40 of the container 2 is made of resin. However, the material forming the lid member, the cap body, and the opening of the container is not limited to resin. As a material for the hinge portion 24, polypropylene, low-density polyethylene, or the like can be used so that the hinge portion 24 does not bend and break. As the material of the blade member 27, polypropylene, high-density polyethylene, or the like can be used so that the blade 271 can break the film member 41. FIG. The film member 41 is not particularly limited as long as it can be broken by the blade member 27 and can seal the contents in the container 2 . For example, aluminum can be used.

A lower surface of the blade member 27 is provided with a pressing portion 273 that takes up slack in the film member 41 by coming into contact with the film member 41 from above while the blade member 27 is inclined toward the film member 41 .

The cover portion 32 of the lid member 30 has a projecting portion 33 projecting toward the upper surface 272 of the blade member 27 . The width of the protrusion 33 in the direction perpendicular to the sliding direction is approximately the same as the width of the upper surface 272 of the blade member 27 . When the lid member 30 slides from the first position to the second position, the protrusion 33 abuts on the upper surface 272 of the blade member 27 and pushes down the blade member 27 , thereby causing the blade 271 of the blade member 27 to move toward the film member 41 . is configured to break the

5A, 5B, 5C, and 5D illustrate the process of opening the container 2 by sliding the lid member 30 from the first position to the second position, using cross-sectional views along the AA cross-section of FIG. It is a figure to do. 5A shows the lid member 30 in the first position, FIG. 5D shows the lid member 30 in the second position, and FIGS. 5B and 5C show the lid member 30 in the first position and the second position. indicates a position in between.

As shown in FIG. 5A , when the lid member 30 is in the first position, the pouring portion 21 is closed by the cover portion 32 . At this time, the protrusion 33 is positioned on the blade 271 side of the blade member 27 and is not in contact with the upper surface 272 of the blade member 27 .

As shown in FIG. 5B, when the protruding portion 35 is pushed, the engaging portion 34 is disengaged, the cover member 30 starts to move from the first position in the sliding direction S, and the protrusion 33 moves toward the upper surface of the blade member 27. As shown in FIG. 272.

The sliding direction S of the lid member 30 and the upper surface 272 of the blade member 27 are not parallel, and the sliding direction S is inclined downward with respect to the upper surface 272 of the blade member 27 . When the cover member 30 moves further in the slide direction S, the protrusion 33 slides on the upper surface 272 of the blade member 27 from near the blade 271 toward the hinge portion 24 while contacting the upper surface 272 of the blade member 27 . The contact position between the protrusion 33 and the upper surface 272 of the blade member 27 moves toward the hinge portion 24 and moves downward. Therefore, the blade member 27 is pushed downward by the protrusion 33 . The hinge portion 24 is plastically deformed and bent, and the blade member 27 tilts downward so as to rotate in the direction indicated by the arrow R about the hinge portion 24 as an axis.

As shown in FIG. 5C, when the blade member 27 tilts downward, the holding portion 273 contacts the film member 41, and the slack in the film member 41 is removed. The blade 271 of the blade member 27 pierces the film member 41 in a state in which the slack is removed.

As shown in FIG. 5D, when the lid member 30 is further moved in the slide direction S and pushed until it reaches the second position, the projection 33 pushing down the upper surface 272 of the blade member 27 approaches the hinge portion 24 side. The blade member 27 is greatly tilted downward and breaks through the film member 41 . Further, the pouring part 21 is opened by moving the cover part 32, and the unplugging operation is completed.

6A and 6B are cross-sectional views taken along line AA in FIG. 1 for explaining the process of closing (re-sealing) the container 2 again by sliding the lid member 30 from the second position to the first position. 6A shows the lid member 30 at the second position, and FIG. 6B shows the lid member 30 at the first position.

FIG. 6A corresponds to the state of completion of the unplugging operation of FIG. 5D. From this state, the lid member 30 starts to move in the slide direction T from the second position by pushing the side wall portion 39 on the side opposite to the slide direction T of the lid member 30 . The sliding direction T is the sliding direction of the lid member 30 during resealing, and is opposite to the sliding direction S of the lid member 30 during the opening operation shown in FIGS. 5A to 5D.

As shown in FIG. 6B, when the lid member 30 slides to the first position, the annular concave portion 321 and the annular convex portion 211 shown in FIG. A reliable reseal is performed. The engaging portion 34 is formed by the engagement between the annular concave portion 321 and the convex portion 211, so that the sliding movement of the lid member 30 in the sliding direction S is restricted. Since the hinge portion 24 is plastically deformed and bent during the opening operation, the blade member 27 does not return to its position even if the protrusion 33 separates from the upper surface 272 of the blade member 27 . The hinge portion 24 may be configured to bend due to elastic deformation during the opening operation, and the blade member 27 may return to the position shown in FIG.

(Excellent points of the cap and container of the present embodiment)
Since the lid member 30 of the container 2 having the cap 1 of this embodiment slides linearly, the contact point between the protrusion 33 and the blade member 27 moves downward when the lid member 30 is slid a certain amount. The amount is constant regardless of the sliding position of the lid member 30 . As the cover member 30 approaches the second position from the first position, the distance between the protrusion 33 and the hinge 24 becomes shorter, and the position where the protrusion 33 pushes the upper surface 272 of the blade member 27 (the position where it contacts the upper surface 272). The distance in the sliding direction from the hinge portion 24, which is the center of rotation, is shortened. If the arc length is the same, the angle is inversely proportional to the radius. Therefore, even if the amount of downward movement of the point of contact between the protrusion 33 and the blade member 27 is constant, the rotation angle of the blade member 27 is It becomes large as it approaches the 2nd position from the 1st position. Therefore, as the projecting portion 33 approaches the hinge portion 24, the blade 271 of the blade member 27 breaks the film member 41 with a large stroke, and the film member 41 is largely unsealed by the rotational motion. Therefore, even if the vertical stroke of the protrusion 33 is small, the blade 271 can secure a large stroke, so that even if the film member 41 is somewhat slack, it can be broken through.

When the protruding portion 35 of the lid member 30 of the container 2 equipped with the cap 1 of the present embodiment is pushed obliquely downward, the user must move the protruding portion 23 or a portion near it that does not hinder the sliding movement of the lid member 30. Of the fingers of the hand that pushes in the cover member 30, the finger (for example, the index finger) other than the finger (for example, the thumb) used to push the projecting portion 35 may be used for support. That is, in the container 2 provided with the cap 1 of this embodiment, the operation of pushing the lid member 30 in order to open the cap can be performed with one hand. The container 2 can be opened by a simple one-handed operation of pushing the lid member 30 and sliding it from the first position to the second position. In addition, the opened container 2 can be resealed by one simple operation of sliding the slid lid member 30 in the opposite direction. Therefore, even a handicapped person or an elderly person can easily open the container 2, and even a healthy person can easily open the container 2 with the other hand even when holding something in one hand. can do.

Furthermore, since the blade 271 pierces the film member 41 while the film member 41 is loosened by the pressing portion 273 on the lower surface of the blade member 27, the film member 41 can be opened reliably.

In addition, since the user can put his or her finger on the protruding portion 23 when opening the cap, it is possible to prevent the finger from unintentionally pressing the lid member 30, thereby preventing the finger from sliding the lid member 30. You can avoid getting in the way.

Also, the first end 37 and second end 38 of the slide hole 36 are angled with respect to the slide direction S so that when the boss 28 moves from the first end 37 and second end 38 and When the first end 37 and the second end 38 are reached, there is resistance to movement of the slide portion 31 . This prevents the cover member 30 from unintentionally sliding,
The user can feel a response at the end point of sliding movement of the lid member 30 .

Further, when the lid member 30 is in the first position, the lid member 30 and the cap main body 20 are locked by the engagement portion 34 with a constant locking force. Unintentional sliding movement of the member 30 from the first position is suppressed.

The blade member 27B is connected via a hinge portion 24B to a support portion 25B extending radially inward from the inner surface of the cap body 20B.

The sliding direction S of the lid member 30B and the upper surface 272B of the blade member 27B are not parallel, and the upper surface 272B of the blade member 27B is inclined upward with respect to the sliding direction S. Therefore, as shown in FIG. 8B, when the lid member 30B moves further in the slide direction S, the contact position between the protrusion 33B and the upper surface 272B of the blade member 27B moves toward the hinge portion 24B. The hinge portion 24B is plastically deformed and bent, and the blade member 27B tilts downward so as to rotate in the direction indicated by the arrow R about the hinge portion 24B. As a result, the blade 271B of the blade member 27B pierces the film member 41 .

As shown in FIG. 8C, when the lid member 30B further moves in the slide direction S and reaches the second position, the protrusion 33B that contacts the upper surface 272B of the blade member 27B approaches the hinge portion 24B. The blade member 27B inclines greatly downward and breaks through the film member 41. - 特許庁Further, the pouring part 21B is opened by moving the cover part 32B, and the opening operation of the container 2 is completed.

Thus, in the present invention, the lid member can also be configured to be slidable in the horizontal direction. The sliding direction of the lid member is not limited to the directions of the first and second embodiments. The sliding direction of the lid member and the inclination direction of the upper surface of the blade member may not be parallel, and the configuration may be such that the lid member and the upper surface of the blade member approach each other along the sliding direction. With such a configuration, when the protrusion of the lid member moves from the blade side to the hinge side while contacting the upper surface of the blade member as the lid member slides, the blade member is greatly downwardly centered on the hinge portion. Rotate to tilt. Therefore, the blade of the blade member can pierce the film member with a large stroke.

FIG. 10A shows a state where the cap 1D is attached to the container 2D, and FIG. 10B shows a state where the cap 1D is not attached to the container 2D. Also, FIG. 11B is a cross-sectional view of the cap 1D taken along line CC in FIG. 10A.

Unlike the containers 2 of Examples 1 and 2, the opening 40D of the container 2D of Example 4 is not sealed with a film member. In Example 4, the film member is provided integrally with the cap 1D. As shown in FIG. 11B, below the mounting portion 22D of the cap main body 20D, there is provided a flange portion 220D attached to the peripheral portion of the opening portion 40D by welding. A film member 221D is provided inside the mounting portion 22D and above the flange portion 220D.

In Example 4, when the cover member 30D is slid, the blade member 27D opens the film member 221D provided on the cap main body 20D. A mechanism for opening the film member 221D by the blade member 27D is the same as that of the first embodiment, so detailed description thereof will be omitted.
