Description

The present invention relates to a cap unit and a capped container.

Conventionally, there have been capped containers equipped with a cap unit (stopper) that can be detachably attached to a container body with an open top. Among these, a proposed cap unit with a straw includes a cap body that closes the top opening of the container body and has a flexible straw protruding from the top, a lid body that is rotatably attached to the cap body via a hinge, a lid locking mechanism that secures the lid body to the cap body, and a waterproof gasket (sealing member) that seals the gap between the container body and the cap body (see, for example, Patent Documents 1 and 2 listed below).

In a beverage container equipped with such a cap unit, when the lid is secured to the cap body by the lid locking mechanism, the straw is placed inside the lid in a bent state. Furthermore, a protrusion on the inside of the lid abuts the straw, crushing it and blocking the straw's liquid passage. Meanwhile, when the lid is released from its locked position by the lid locking mechanism, the straw elastically returns from its bent state to its original state while rotating the lid in the opening direction. This allows the beverage inside the container body to be consumed through the straw.

Patent No. 4524681 Patent No. 5662536

In the cap unit with a straw described above, when the lid is released from its locked position by the lid locking mechanism, the air inside the container body is released to the outside (the pressure inside the container is released to the outside) through a vent hole located at the top of the cap body to prevent the remaining liquid in the straw from splashing out.

In this case, it is necessary to ensure that the air vent is opened before the straw elastically returns to its original state from its bent state. In addition, when the lid body is fixed to the cap body by the lid locking mechanism, the air vent must be reliably closed.

The ventilation hole is the center hole of a cylindrical protrusion provided on the waterproof gasket. The waterproof gasket is made of a ring-shaped elastic member and is fitted inside the cap body with the cylindrical protrusion protruding upward from a through-hole provided in the top of the cap body.

In this case, the cylindrical protrusion must be press-fit into the through-hole from below, and the waterproof gasket must be fixed in an appropriate position inside the cap body. Furthermore, if the cylindrical protrusion is not press-fitted into the through-hole sufficiently, when the protrusion to close the air vent presses against the cylindrical protrusion, the cylindrical protrusion may fall off the through-hole, or the pressure from the protrusion may be insufficient, making it difficult to properly open and close the air vent. This may also cause the beverage inside the container body to leak to the outside.

In addition, when fitting the waterproof gasket inside the cap body, it is difficult to visually check whether the cylindrical protrusion has been securely pressed into the through-hole, and if the cylindrical protrusion is not pressed into the through-hole sufficiently, the waterproof gasket may become misaligned when the cap body is screwed onto the neck of the container body.

The present invention was proposed in light of these conventional circumstances, and aims to provide a cap unit with a straw that prevents the beverage inside the container body from leaking out and allows the air vent to be opened and closed appropriately, as well as a capped container that, by being equipped with such a cap unit, allows for further improvements in usability.

As shown in Figures 1 to 4, the capped container 100 of this embodiment is a beverage container that includes a cap unit 1 with a straw and a container body 2 to which the cap unit 1 is detachably attached, and allows the beverage (liquid) in the container body 2 to be drunk through the straw portion 7a, which will be described later.

In addition, in the capped container 100 of this embodiment, the container body 2 has a vacuum insulation structure, making it possible to keep the beverage (contents) contained in the container body 2 cold (or hot).

Specifically, the container body 2 has a cylindrical outer container 3 and inner container 4 with a bottom, both made of stainless steel or the like, and is configured as a double-walled container with the inner container 4 housed inside the outer container 3 and the mouths of the two joined together. A vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed, for example, by blocking a vent hole provided in the center of the bottom of the outer container 3 in a chamber that has been depressurized (evacuated) to a high vacuum.

The container body 2 has a substantially circular bottom 2a, a substantially cylindrical body 2b that rises from the outer periphery of the bottom 2a, and a substantially cylindrical mouth/neck 2c that narrows in diameter at the upper side of the body 2b. The upper end of the mouth/neck 2c opens in a circular shape as the upper opening 2d of the container body 2.

In the capped container 100 of this embodiment, the container body 2 has an overall, generally cylindrical external shape, but the external shape of the container body 2 is not particularly limited and can be modified as appropriate to suit the size, design, etc. In addition, the outer peripheral surface of the container body 2 may be painted, printed, etc.

As shown in Figures 2 to 7, the cap unit 1 of this embodiment comprises a cap body 6 that closes the upper opening 2d of the container body 2, a straw member 7 including a straw portion 7a that protrudes from the top of the cap body 6, a lid body 9 that is rotatably attached to the cap body 6 via a first hinge portion 8, a lid locking mechanism 10 that secures the lid body 9 to the cap body 6, and a valve member 11 that is attached to the upper part of the cap body 6 between the straw portion 7a and the lid locking mechanism 10.

In the capped container 100 of this embodiment, the side of the cap unit 1 on which the first hinge portion 8 is provided is referred to as the "rear side," and the side opposite the side on which the first hinge portion 8 is provided is referred to as the "front side."

The cap body 6 is made of a synthetic resin, such as polypropylene. The cap body 6 has a peripheral wall portion 6a formed in a generally cylindrical shape and an upper wall portion 6b that covers the upper surface of the peripheral wall portion 6a.

The cap body 6 is detachably attached to the neck portion 2c of the container body 2 by threading. To this end, a female thread portion 12 is provided on the inner surface of the peripheral wall portion 6a. Meanwhile, a male thread portion 13 that threads into the female thread portion 12 is provided on the outer surface of the neck portion 2c of the container body 2.

The cap body 6 has an attachment hole 14 that penetrates approximately the center of the upper wall portion 6b, and a fitting protrusion 15 that is located forward of the attachment hole 14 and protrudes from the underside of the upper wall portion 6b.

The straw member 7 is made of an elastic material such as silicone rubber or elastomer, and has a tubular straw portion 7a, a seal portion 7b that protrudes radially from the middle of the length of the straw portion 7a, a fitting hole 7c provided in the seal portion 7b, and a pipe connection portion 7d provided at the lower end of the straw portion 7a.

The straw member 7 is removably attached to the cap body 6 by inserting the straw portion 7a through the mounting hole 14, fitting the fitting protrusion 15 into the fitting hole 7c, and then fitting the seal portion 7b inside the cap body 6.

Furthermore, the straw member 7 can be removed from the cap body 6 and washed separately from the cap body 6, allowing the space between the straw member 7 and the cap body 6 to be kept hygienic.

The straw portion 7a protrudes from the top of the cap body 6 and is bent forward.

When the cap body 6 is attached to the neck portion 2c of the container body 2, the sealing portion 7b comes into close contact with the upper opening 2d (the upper end of the neck portion 2c) all around, thereby functioning as a waterproof gasket that seals the space between the container body 2 and the cap body 6.

A suction pipe 16 is connected to the pipe connection portion 7d, which draws in the beverage contained in the container body 2. The suction pipe 16 extends cylindrically from the pipe connection portion 7d to near the bottom of the container body 2. This allows the beverage to be consumed to the last drop, even when there is little beverage left in the container body 2.

The lower end of the suction pipe 16 can also be modified as needed, with a portion cut out at an angle or cut out in a wave-like pattern. This prevents the suction pipe 16 from sticking or making it difficult to drink the beverage inside the container body 2, even if the lower end of the suction pipe 16 abuts against the inside bottom or side of the container body 2.

The lid 9 is made of a synthetic resin such as polypropylene. The lid 9 has a generally cylindrical peripheral wall 9a and a top wall 9b that covers the top surface of the peripheral wall 9a. The lid 9 is rotatably attached to the cap body 6 via a first hinge 8 provided at the top of the rear end of the cap body 6.

In addition, a protrusion 17 protrudes downward from the underside of the inside of the lid 9. The straw portion 7a is stored inside the lid 9 in a folded state by this protrusion 17.

The lid locking mechanism 10 includes a locking member 19 rotatably attached to the front side of the cap body 6 via a second hinge portion 18, a biasing member 20 that biases the locking member 19 toward one side in the rotation direction, and a stopper portion 21 provided on the locking member 19.

The locking member 19 has an upper arm portion 19a extending upward from the second hinge portion 18, a lower arm portion 19b extending downward from the second hinge portion 18, and a rear arm portion 19c extending rearward from the upper arm portion 19a.

The biasing member 20 is made of an elastic material such as a coil spring. The biasing member 20 is disposed in a compressed state between the lower arm portion 19b and the peripheral wall portion 6a. It is also possible to use an elastic material such as rubber (e.g., silicone rubber) or elastomer for the biasing member 20.

The stopper portion 21 protrudes downward from the tip of the rear arm portion 19c.

The lid locking mechanism 10 has a first locking portion 22 provided on the locking member 19 side and a first locked portion 23 provided on the lid body 9 side. The first locking portion 22 consists of a hook portion that protrudes rearward from the tip of the upper arm portion 19a. The first locked portion 23 consists of a hook portion that protrudes forward from the lower end of the front side of the lid body 9.

As shown in Figure 2, in the lid locking mechanism 10, when the lid 9 closes the top of the cap body 6, the first engaging portion 22 on the locking member 19, which is biased by the biasing member 20, engages with the first engaged portion 23 on the lid 9, thereby securing the lid 9 to the cap body 6.

The locking member 19 is rotatable between a locked position in which the first engaging portion 22 is engaged with the first engaged portion 23, and an unlocked position in which the engagement between the first engaging portion 22 and the first engaged portion 23 is released.

Therefore, as shown in Figure 3, in the lid locking mechanism 10, by pressing the lower arm portion 19b of the locking member 19 against the biasing force of the biasing member 20, it is possible to rotate the locking member 19 from the locked position to the unlocked position, thereby releasing the locked state between the first locking portion 22 and the first locked portion 23.

The lid locking mechanism 10 also has a second locking portion 24 provided on the locking member 19 side and a second locked portion 25 provided on the lid body 9 side. The second locking portion 24 consists of a hook portion that protrudes upward from the tip of the rear arm portion 19c. The second locked portion 25 consists of a hook portion that protrudes rearward from the lower end of the front side of the lid body 9.

In the lid locking mechanism 10, as shown in FIG. 2, when the lid body 9 is fixed to the cap body 6, the lower arm portion 19b of the locking member 19 is pressed as shown in FIG. 3, causing the locking member 19 to rotate from the locked position to the unlocked position. This releases the engagement between the first locking portion 22 and the first locked portion 23, and then the second locking portion 24 on the locking member 19 engages with the second locked portion 25 on the lid body 9. This restricts rotation of the lid body 9 to one side (opening direction).

In the lid locking mechanism 10, from the unlocked state shown in Figure 3, as shown in Figure 4, the pressure on the locking member 19 is released, and the locking member 19, biased by the biasing member 20, rotates from the unlocked position to the locked position, thereby releasing the engagement between the second engaging portion 24 and the second engaged portion 25. This allows the lid 9 to rotate (open and close).

On the other hand, in the lid locking mechanism 10, by rotating the lid 9 from the position shown in FIG. 4 in a direction that closes the top of the cap body 6 (closing direction), the first engaging portion 22 and the first locked portion 23 come into sliding contact with each other, and the locking member 19 rotates from the locked position to the unlocked position against the bias of the biasing member 20. Furthermore, as the first engaging portion 22 overcomes the first locked portion 23, the locking member 19 is rotated from the unlocked position to the locked position by the bias of the biasing member 20. At this time, the first engaging portion 22 is locked to the first locked portion 23. As a result, the lid 9 closes the top of the cap body 6, as shown in FIG. 2, and the lid 9 can be fixed to the cap body 6.

As shown in FIGS. 2 to 7, the valve member 11 is made of an elastic material such as rubber, elastomer, or the like, such as silicone rubber, and is formed in the shape of a generally rectangular flat plate as a whole.
The valve member 11 has a cylindrical projection 27 with a first vent hole 26 formed on the front side thereof, and a second vent hole 28 on the rear side thereof.

The cap body 6 has a fitting portion 29 into which the valve member 11 is fitted, a first through-hole 30 that penetrates the front side of the bottom of the fitting portion 29, and a second through-hole 31 that penetrates the rear side of the bottom of the fitting portion 29.

The valve member 11 is removably attached to the cap body 6 by fitting the cylindrical protrusion 27 into the first through-hole 30 and then fitting it inside the fitting portion 29. This places the second air vent 28 in communication with the second through-hole 31.

Furthermore, the valve member 11 can be removed from the cap body 6 and washed separately from the cap body 6, making it possible to maintain hygienic conditions between the valve member 11 and the cap body 6.

In this embodiment, the fitting portion 29 is configured as a recess provided in the upper part of the cap body 6, but this configuration is not necessarily limited to this. For example, it may be configured such that a rib protrudes from the upper surface of the cap body 6 into which the valve member 11 can be fitted.

In the cap unit 1 of this embodiment, which has the above-described configuration, as shown in Figure 2, when the lid body 9 closes the top of the cap body 6, the straw portion 7a is stored inside the lid body 9 in a state where it is bent at two points. Furthermore, the protrusions 17 that come into contact with the straw portion 7a crush the straw portion 7a, blocking the liquid passage of the straw portion 7a.

At this time, the stopper portion 21 of the locking member 19 comes into tight contact with the periphery of the first air vent 26 of the valve member 11, thereby blocking the first air vent 26. Furthermore, the straw portion 7a, which has been crushed by the protrusion 17 of the lid body 9, comes into tight contact with the periphery of the second air vent 28, thereby blocking the second air vent 28.

This prevents the beverage inside the container body 2 from leaking out when the lid body 9 is closed off at the top of the cap body 6.

In the cap unit 1 of this embodiment, from the closed state shown in Figure 2, pressing the lower arm portion 19b of the locking member 19, as shown in Figure 3, rotates the locking member 19 from the locked position to the unlocked position, thereby releasing the locked state between the first locking portion 22 and the first locked portion 23.

At this time, the second locking portion 24 locks into the second locked portion 25. Furthermore, the stopper portion 21 of the locking member 19 moves away from the periphery of the first air vent 26, opening the first air vent 26.

Furthermore, when the locking member 19 is rotated from the locked position to the unlocked position, the first air vent 26 is opened before the cover 9 is rotated in the open direction. At this time, the first air vent 26 is opened before the first engaging portion 22 and the first engaged portion 23 are released from their locked state.

This allows the air inside the container body 2 to be released to the outside through the first air vent 26 (releasing the pressure inside the container body 2 to the outside), and then the straw portion 7a elastically returns to its original position, opening the liquid passage in the straw portion 7a and preventing any remaining liquid in the straw portion 7a from splashing to the outside.

In the cap unit 1 of this embodiment, when the pressure on the locking member 19 is released from the unlocked state shown in Figure 3 as shown in Figure 4, the locking member 19, biased by the biasing member 20, rotates from the unlocked position to the locked position, and the second locking portion 24 and the second locked portion 25 are released from their locked state.

At this time, the straw portion 7a pushes up the lid body 9 and elastically returns from its bent state to its original state. As the straw portion 7a elastically returns to its original state, the lid body 9 is rotated in the opening direction. Furthermore, the straw portion 7a moves away from the periphery of the second air vent 28, opening the second air vent 28.

Meanwhile, the stopper portion 21 of the locking member 19 comes into close contact with the periphery of the first air vent 26, closing the first air vent 26 again. This prevents the beverage inside the container body 2 from leaking out, while allowing the beverage inside the container body 2 to be suctioned and drunk through the straw portion 7a.

Furthermore, as the beverage inside the container body 2 decreases, the pressure inside the container body 2 becomes negative. At this time, outside air is introduced into the inside of the container body 2 through the second air vent 28. This returns the pressure inside the container body 2 to atmospheric pressure, allowing the beverage inside the container body 2 to continue to be consumed through the straw portion 7a.

As described above, in the cap unit 1 of this embodiment, the valve member 11, which is provided with the first and second air vents 26 and 28 described above, is configured to fit into the fitting portion 29 provided on the top of the cap body 6, making it possible to attach the valve member 11 to an appropriate position on the cap body 6.

In addition, in the cap unit 1 of this embodiment, the valve member 11, which is separate from the straw member 7 described above, is attached to the outside of the cap body 6, so there is no misalignment of the first air vent 26 and second air vent 28 provided in the valve member 11.

Furthermore, in the cap unit 1 of this embodiment, the stopper portion 21 provided on the locking member 19 described above allows the first air vent 26 provided in the valve member 11 to be opened and closed appropriately. It is also easy to align the second through-hole 31 provided in the cap body 6 with the second air vent 28 provided in the valve member 11.

In addition, with the cap unit 1 of this embodiment, the valve member 11 is attached to or detached from the cap body 6 by pressing the lower arm portion 19b of the locking member 19 against the bias of the biasing member 20 described above, rotating the locking member 19 from the locked position to the unlocked position, thereby preventing the valve member 11 from being accidentally removed. Furthermore, the stopper portion 21 of the locking member 19, biased by the biasing member 20 described above, comes into contact with the valve member 11, thereby preventing the valve member 11 from falling off the cap body 6.

In addition, in the cap unit 1 of this embodiment, the sealing portion 7b is fitted to the inside of the cap body 6 with the fitting protrusion 15 of the cap body 6 fitted into the fitting hole 7c of the straw member 7 described above. This makes it possible to prevent twisting or misalignment of the sealing portion 7b, which is in sliding contact with the upper opening 2d (the upper end of the neck portion 2c), when the cap body 6 is attached to the neck portion 2c of the container body 2 by screwing.

In addition, the cap unit 1 of this embodiment uses a straw member 7 in which the straw portion 7a and seal portion 7b described above are integrated, simplifying the structure and making it easier to attach and detach from the cap body 6.

As described above, the cap unit 1 of this embodiment prevents the beverage inside the container body 2 from leaking to the outside, and also makes it possible to properly open and close the first vent hole 26 and the second vent hole 28, which release air inside the container body 2 to the outside. Therefore, by including such a cap unit 1, the capped container 100 of this embodiment can further improve usability.

The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, the cap unit 1 is not necessarily limited to the configuration of the valve member 11 described above, and may be configured as a valve member 11A shown in Fig. 8. The valve member 11A has a cylindrical protrusion 27 with a first air vent 26 on the front side and a second air vent 28 on the rear side.

In this configuration, the cylindrical protrusion 27 of the valve member 11A is fitted into the second through-hole 31 of the cap body 6, and the valve member 11A is fitted into the fitting portion 29 of the cap body 6 with the first vent hole 26 of the valve member 11A communicating with the first through-hole 30 of the cap body 6.

Furthermore, the cap unit 1 may be configured to have a notched recess 32 around the fitting portion 29, as shown in Figure 9, to make it easier to remove the valve member 11 from the fitting portion 29.

Furthermore, the cap unit 1 may be configured such that a gripping piece 33 is provided on the valve member 11, as shown in Figure 10, and the valve member 11 can be easily removed from the fitting portion 29 by pulling this gripping piece 33.

Furthermore, when such a gripping piece 33 is provided, as shown in Figure 11, the straw portion 7a is crushed by the protrusion 17 of the lid body 9, bending the gripping piece 33 and making tight contact with the periphery of the second air vent 28, thereby blocking the second air vent 28.

Furthermore, in the cap unit 1, as shown in Figure 12, the sealing portion 7b of the straw member 7 can be configured as a waterproof gasket 34 provided separately from the straw member 7.

In the above embodiment, the present invention is illustrated as being applied to a capped container 100 that has a cold (or hot) insulation function provided by a container body 2 with a vacuum insulation structure, but the present invention is not necessarily limited to containers equipped with a container body 2 with such a vacuum insulation structure.
