Description

Cap assembly and container comprising same

Technical Field

The present utility model relates to a cap assembly for opening and closing a drink opening and a vent opening, and more particularly, to a cap assembly for opening and closing a drink opening and a vent opening having a trigger assembly. The utility model also relates to a container comprising such a cap assembly.

Background

Various beverage containers exist in the prior art that are capable of insulating fluids. Generally, these beverage containers are provided with a lid assembly that includes a pivotable beverage port that is configured to assume a stowed configuration and an open configuration. In the stowed configuration, the drink opening is curved downwardly to be received within a compartment formed by the lid shell. In the open configuration, the beverage port is curved upwardly to dispense the beverage. However, because the hot beverage container accumulates the hot gas pressure when the beverage port is in the stowed configuration, the hot gas pressure and hot beverage are rapidly ejected or shallowly ejected from the beverage port when the beverage port is transitioned from the stowed configuration to the open configuration. Such spraying or shallow spraying is more likely to burn the user in addition to causing inconvenience to the user. Although similar products are available in the market which involve a pressure relief effect when the beverage port is opened, the pressure relief effect is substantially synchronous with the opening of the beverage port, and there is always a chance that hot gas pressure and hot beverage will be sprayed or shallowly sprayed from the beverage port, which is undesirable.

To solve this problem, the present utility model provides a cap assembly for opening and closing a beverage port and a vent port with a trigger assembly. Or at least provide the public with an alternative.

Detailed Description

The present utility model will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present utility model more apparent.

It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present utility model should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present utility model belongs. The terms "first," "second," and the like, as used in embodiments of the present utility model, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The terms "front", "rear", "left", "right", "upper" and "lower" and the like refer to orientation or similar terms and are merely described with respect to the exemplary relative positional relationships shown in the drawings to facilitate understanding by those skilled in the art, and are not intended to limit the components within the utility model to only such specific relative positional relationships. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, whether direct or indirect.

As shown in fig. 1A, the cap assembly includes a cap body 10, a drink opening unit 30, a cap member 40, a button 513 of a trigger assembly (the trigger assembly will be described in detail later), a lock 70, and a handle unit 80. When the handle unit 80 is assembled to the cap 10, the space formed by the assembly of the handle unit 80 and the cap 10 defines the head space of the cap 10 to accommodate the drink opening unit 30 and the cap 40. Fig. 1A shows a schematic view of the structure of the drink opening unit 30 and the lid 40 in an open state. In the embodiments of the drawings, by "open condition of the beverage port unit" is meant that the beverage port unit 30 is configured to be in a flipped-up exposed condition, the beverage port unit 30 being in fluid communication with the container in which the lid assembly is assembled; by "open state of the cover" is meant that the cover 40 is configured to be in a flipped-up exposed state. Fig. 1B shows a schematic view of the structure of the beverage port unit 30 and the lid 40 in a closed state. As shown in fig. 1B, when the drink opening unit 30 and the lid 40 are arranged in a substantially horizontal direction, the drink opening unit 30 and the lid 40 are accommodated in the head space of the lid body 10, and the drink opening unit 30 is covered under the lid 40 by the lid 40. In the embodiments of the figures, by "closed state of the beverage port unit" is meant that when the beverage port unit 30 is configured in a substantially horizontal state, the beverage port unit 30 is covered by the lid 40 below the lid 40, the beverage port unit 30 being not in fluid communication with the container in which the lid assembly is assembled; the "closed state of the cover" means that the cover 40 is arranged in a substantially horizontal state. The open/closed states described herein with respect to the drink opening unit 30 and the lid 40 are understood to mean that the drink opening unit 30 and the lid 40 are in their open/closed positions, and vice versa, unless otherwise defined herein.

Referring to fig. 1A and 1B, the lid 10 may be generally in the form of an inverted bowl having a top space adapted to receive the drink spout unit 30 and the lid 40, a bottom opening for attachment to the open top of the container body, such as by threaded engagement. It should be noted that the shape of the cover 10 of the present utility model is not limited to the above-described shape, but may be other shapes, such as a hemisphere, a cuboid, or other three-dimensional structures. When both the mouthpiece unit 30 and the cover 40 are in an open state, as shown in fig. 1A, the cover 40 is at an angle to the top opening of the cover 10. When both the mouthpiece unit 30 and the cover 40 are in the closed state, as shown in fig. 1B, both the mouthpiece unit 30 and the cover 40 are substantially accommodated in the head space of the cover 10. As shown in fig. 1A and 1B, the beverage port unit 30 and the cover 40 are both pivotally disposed on top of the cover 10 and are respectively operable between an open state and a closed state, and it is seen that the beverage port unit 30 and the cover 40 are both pivotally movable relative to the cover 10. Taking fig. 1A and 1B as an example, the directions of the pivotal movement of the drink opening unit 30 and the lid member 40 are opposite. However, it is understood that the operation of the opening/closing states of the drink opening unit 30 and the cover 40 may be independent of each other or may be cooperatively operated according to actual needs. In the embodiment in the drawings, when the push button 513 of the trigger assembly is pushed to move inward, the drink port unit 30 is released from its closed position or closed state, and the lid 40 is also pivoted upward to be released from its closed position or closed state (the state from fig. 1B to fig. 1A). It is to be particularly understood that the beverage port unit 30 is first released from its closed position or closed condition, and subsequently the cover 40 is also released from its closed position or closed condition.

As shown in fig. 3 and 4, which schematically illustrate specific structures of the drink port unit 30 according to one embodiment of the present utility model, respectively. The beverage port unit 30 comprises a beverage port 31 and a beverage channel 32. The beverage channel 32 has a collapsible channel upper portion 321 connected to the inner end of the beverage mouthpiece 31 and a channel lower portion 322 in fluid communication with the interior of the beverage container. The beverage mouthpiece 31 is typically made of a plastic material and when the beverage mouthpiece unit 30 is in an open state, the beverage mouthpiece 31 protrudes out of the cover 10. Unless otherwise defined herein, references to the beverage port unit 30 being in its open/closed state or in its open/closed position are to be understood as meaning that the beverage port unit 30/beverage port 31/beverage channel 32/channel upper 321 is in its open/closed state or in its open/closed position and vice versa. In practice, it is preferred that the collapsible channel upper 321 be made of an elastic material, such as silicone, polytetrafluoroethylene (PTFE), polyethylene (PE), so that the channel upper 321 can be bent or folded to block the beverage channel 32. The collapsible channel upper 321 extends through a through hole 20 (shown in fig. 2A and 2B) formed in the cover 10 and is closed by manually pushing the drink spout 31 downwardly into engagement with the trigger assembly and is covered underneath by the cover 40. When the upper channel portion 321 is released from the bent or folded state, since the upper channel portion 321 may be made of an elastic or flexible material such as silicone, polytetrafluoroethylene (PTFE), polyethylene (PE), etc., the physical properties of the upper channel portion 321 itself allow it to automatically return to its open state without being pressed, i.e., the upper channel portion 321 automatically performs a pivoting movement to return to its open position.

In one embodiment, the cap assembly of the present utility model may also be provided with a button 513, and when pressure is applied to the button 513 of the trigger assembly, the drink spout 31 can disengage from the trigger assembly, thereby bouncing upward and moving away from the cap 40, which results in the collapsible drink channel 32 returning to its open state. In the embodiment of the drawings, by "beverage passage returning to its open state" open state, it is meant that the upper portion 321 of the passage is released from being bent or folded when the drink spout 31 is sprung up and moved away from the lid 40. It is to be understood that the mouthpiece unit 30 and the cover 40 in the embodiment of the present utility model can be switched between an open state and a closed state. In the opened state of the beverage port unit 30 and the lid 40, both the lid 40 and the beverage port 31 of the beverage port unit 30 are pivoted away from the lid body 10, and the beverage passage 32 connected to the beverage port 31 is opened, thereby allowing a user to drink the beverage contained in the container through the beverage port 31. In the closed state of the beverage port unit 30 and the lid 40, the beverage port unit 30 is pivoted towards the lid 10 and closed in a position substantially transverse to the longitudinal axis of the beverage container (i.e. the headspace of the lid 10), and the beverage port 31 is folded about 90 ° to be restrained under the lid 40, which results in the foldable channel upper portion 321 of the beverage channel 32 also being folded about 90 °, thereby blocking the beverage channel 32.

Fig. 5A-5B and 6 illustrate an overall block diagram and cut-away view, respectively, of a trigger assembly according to one embodiment of the present utility model. The trigger assembly 50 includes: a button 513; the moving member 500 is composed of, for example, a front member 51 (or a first member) having a substantially Y-shape and a rear member 52 (or a second member) having a substantially Y-shape; a first elastic portion 514; and a second elastic portion 523. In some embodiments, at least one of the first elastic portion 514 and the second elastic portion 523 may be a compression spring. As shown in fig. 5A-5B and 6, the front member 51 has a first end 511 provided with an operating portion, and an opposite second end 512. A first bifurcated portion 512A and a second bifurcated portion 512B at the second end 512 extending from the first end 511 of the operating portion. The button 513 is provided at an outer end of the first end 511 of the operation part. A first elastic portion 514 is connected between the inner end surface of the button 513 and the cover 10, and the first elastic portion 514 can apply an outward pressure to the button 513 to resist a force applied by a user pressing the button 513. The rear member 52 is operatively coupled to the front member 51 to define an opening 53 through which the collapsible beverage channel 32 passes. The position of the opening 53 corresponds to the position of the through hole 20 for the upper foldable channel portion 321 to extend through the cover 10. The structure of the rear member 52 is similar to the front member 51, and thus the structure of the rear member 52 similar to the structure of the front member 51 will not be described again. The rear member 52 has a first end 521, an opposite second end 522, the second end 522 terminating with a second resilient portion 523, a first bifurcated portion 521A at the first end 521, and a second bifurcated portion 521B. The second resilient portion 523 is configured to apply an outward pressure to the second end 522 of the rear member 52, thereby applying a pressure to the front element 51. It will be appreciated that when the first resilient portion 514 does not apply any pressure to the front member 51, the front member 51 is in the first position. When the front member 51 is not in contact with the rear member 52, the rear member 52 is in the first position. When the button 513 is pressed, the first elastic portion 514 applies pressure to the front member 51 to bring the front member into the second position. When the front member 51 moves from the first position to the second position, the front member 51 advances the rear member 52, causing the rear member 52 to move from the first position to the second position. The second elastic portion 523 is constantly pressed when the rear member 52 moves from the first position to the second position. It should be understood that the second position of the front and rear members 51, 52 is defined as a position in which the beverage port unit 30 is pivotable upward, and is not limited to the extended state of the first and/or second elastic portions 514, 523. When the pressed button 513 is released, the pressed first elastic portion 514 is released accordingly, and the front member 51 moves back from the second position to the first position. When the front member 51 moves from the second position to the first position, the pressed second elastic portion 523 is released accordingly and a reaction force is applied to the rear member 52 to move the rear member 52 from the second position back to the first position. When the rear member 52 is moved from the second position to the first position, the front member 51 and the rear member 52 are each in their first positions.

By way of description herein of the example front and rear members 51, 52, the current and rear members 51, 52 are each in their first position, i.e., illustrating how the trigger assembly 50 or the mover 500 is in the first configuration; the current member 51 and the rear member 52 are each in their second position, i.e. illustrating how the trigger assembly 50 or the mover 500 is in the second configuration. It will be appreciated that when the trigger assembly 50 or the mover 500 is in the first configuration, it causes the drink opening unit 30 to assume a closed state; when the trigger assembly 50 or the mover 500 is in the second configuration, it causes the mouthpiece unit 30 to assume an open state. It should be understood that the description of the trigger assembly in the drawings should not limit the spirit of the utility model. For example, the mover 500 may be integrally formed instead of two parts (the front and rear members 51 and 52) as shown in the drawings, according to actual needs. The spirit of the present utility model is that the opening/closing state of the drink opening unit can be controlled by moving the trigger assembly. The front and rear members 51, 52 may be configured in other shapes than the generally Y-shape shown in the drawings, as desired. It should be further understood that although the front member 51 and the rear member 52 are Y-shaped in the present embodiment, those skilled in the art can adjust the shape as needed. As long as the shape through which the collapsible beverage channel 32 can pass and/or the open/closed state of the beverage port unit can be controlled by moving the trigger assembly.

As shown in fig. 7, in one embodiment, the foldable channel upper portion 321 of the beverage channel 32 of the beverage port unit 30 has a coupler 323, the coupler 323 being formed on a side surface of the beverage port unit 30, which is a side of the beverage port unit 30 that faces the cover 10 when in its closed position. As shown in fig. 3, 4, and 7, the coupler 323 is designed to have a wedge shape and is formed on a side surface of the drink opening unit 30. The coupling 323 has a recess, the recess opening being positioned in the same direction as the opening of the mouthpiece 31. The coupler 323 is positioned and configured to be engageable with a projection 524 extending from the first end 521 of the rear member 52. As shown in fig. 7, the protrusion 524 is designed to be hook-shaped and adapted to mate with the wedge-shaped design of the coupler 323 such that when the coupler 323 is pressed downward, the protrusion 524 moves in the direction of the second end 522 of the rear member 52. When the mouthpiece unit 30 in the open state shown in fig. 1A is pressed to pivot downward, the rear member 52 moves toward the second end 522 of the rear member 52 due to the complementary shape design of the coupler 323 and the protrusion 524 (as described above) when the mouthpiece unit 30 is pressed to pivot downward, so that the second end 522 of the rear member 52 applies a force to the second elastic portion 523. When the spout unit 30 continues to pivot downward until the hook-shaped portion of the projection 524 engages the recess of the coupling 323, the pressed second resilient portion 523 then applies a reaction force to the second end 522 of the rear member 52, thereby causing the projection 524 to snap-engage the recess of the coupling 323, such that the spout unit 30 is maintained in a substantially horizontal position, i.e., the spout unit 30 is maintained in a closed position (a closed state as shown in fig. 1B). When the spout unit 30 is in the closed state as in fig. 7, when the user presses the button 513, the front member 51 moves in the direction of the second end 522 of the rear member 52, during which the protrusion 524 of the rear member 52 will disengage from the coupling 323, thereby causing the spout unit 30 to pivot upward (the open state as shown in fig. 1A). It should be understood that the description of the protrusion 524 and the coupling 323 in the drawings should not limit the spirit of the present utility model, and those skilled in the art may adjust the same as the actual need. As long as the trigger assembly 50 or the mover 500 is operable to control the open/close state of the water fountain unit when the first and second configurations thereof are switched.

The trigger assembly may also include a baffle 515. In the embodiment of fig. 3-11, a baffle 515 may be disposed at the inner end of the first bifurcation 512A, the baffle 515 extending downwardly parallel to the longitudinal axis of the lid assembly, but not in contact with the lid body 10 in a vertical direction to leave a space 62 therebetween (see fig. 4). A gap 54 (see fig. 6) is defined between the baffle 515 of the front member 51 and the first end 521 of the rear member 52 adjacent the baffle 515 to allow the front member 51 to move within the gap 54. In the embodiment of fig. 3-11, the presence of a gap 54 between the front member 51 and the rear member 52 is but one preferred embodiment of the present utility model, which provides technical advantages as will be explained below. Those skilled in the art will appreciate that there is no gap 54 between the front and rear members 51, 52 and that the practice of the present utility model is not affected.

Fig. 8 shows an exhaust passage 60 through the cover 10 and in operative communication with the environment. As shown in fig. 8, the vent passage 60 may be an inverted L-shaped passage 61 having a first end 611 extending into the interior of the beverage container and a second end 612 extending generally transversely relative to the longitudinal axis of the cover 10. Although one vent passage 60 is shown in the embodiment of the drawings, it should be understood that one skilled in the art will appreciate that the cover 10 may be configured with at least one vent passage 60 as desired for implementation. When the mouthpiece unit 30 is in the closed state, the second end 612 is closed by the flap 515 of the front member 51. When the push button 513 of the trigger assembly is pushed inwardly, i.e., the flap 515 is moved adjacent the first end 521 of the rear member 52, the flap 515 separates from the second end 612, creating a ventilation path. The vent path is defined by the second end 612 of the channel 60, the baffle 515, and the cover 10, which allows the gas within the container to escape to the environment. The vent channel 60 may be made of a flexible material, such as silicon, or any other suitable material, such as a hard plastic known in the art for use in making food or beverage containers. The exhaust passage 60 may be separately manufactured and installed in the cover body 10. Alternatively, the exhaust passage 60 and the cover 10 may be made of the same plastic material and integrally formed. However, it should be appreciated that while in the embodiment of FIGS. 3-11, the baffle 515 is disposed at the inner end of the first bifurcation 512A, those skilled in the art will appreciate that the baffle 515 may be disposed at the inner end of the first bifurcation 512B and/or that the baffle 515 may be disposed at both bifurcation inner ends of the back member 52, as desired. Although in the embodiment of fig. 3-11, the vent passage 60 is disposed on a side proximate the front member 51, it will be appreciated by those skilled in the art that the particular arrangement/location of the vent passage 60 should cooperate with the arrangement/location of the baffle 515 and vice versa such that operation between the baffle 515 and the vent passage 60 provides a vent path that allows the gas within the container to escape to the environment.

Fig. 9-11 schematically illustrate the process of the trigger assembly according to the present utility model opening the vent and beverage port to drink the beverage in the beverage container. Fig. 9 shows the beverage port unit 30 in a closed state; fig. 10 shows the drink opening unit 30 in an intermediate state (i.e., a state between the closed state and the open state); fig. 11 shows the beverage port unit 30 in an open state. Unless otherwise defined herein, references to the drink opening unit 30 being in an intermediate state are to be understood as referring to the drink opening unit 30 being in an intermediate position between its open and closed positions, and vice versa.

As shown in fig. 9, the beverage port unit 30 is in a closed state. The front and rear members 51 and 52 are in their first positions, respectively. In this first position, the front and rear members 51, 52 are positioned spaced apart from one another in a direction transverse to the cover longitudinal axis to define a gap 54. The channel 60 is closed by the flap 515 and the mouthpiece unit 30 is in a closed condition and restrained under the cover 40. The collapsible channel 32 of the drink spout 31 is folded and squeezed in this position, thereby blocking the drink channel.

Referring to fig. 10, when the user presses the button 513 inward, the pressed first elastic portion 514 abuts against the front member 51 to move from the first position toward the rear member 52. During this time, the baffle 515 is driven away from the channel 60, and the baffle 515 separates from the second end 612, forming a ventilation path. The vent path is defined by the second end 612, the baffle 515, and the cover 10, which allows the gas within the container to escape to the environment. In particular, second end 612 defines a space 62 with baffle 515 and cover 10 in a vertical direction to allow heat, vapor, or gas to escape through channel 61 through space 62 to the headspace of cover 10. During inward advancement of the front member 51 in the gap 54, the rear member 52 is not subjected to any pressure before the front member 51 moves into contact with the rear member 52, and thus the rear member 52 is held in its first position, with the foldable channel upper portion 321 of the beverage channel 32 still engaged with the rear member 52. The beverage port unit 30 is held in its closed folded position in which it is not permitted to drink the beverage in the container. The structure of the trigger assembly ensures that heat, steam or gas that may accumulate in the container is released after the push button 513 is moved inward but before the mouthpiece unit 30 is opened, thereby preventing the heat, steam or gas from being ejected from the container onto the face of the user to cause discomfort when the mouthpiece unit 30 is opened to drink the beverage. In this way, the pressure built up inside the container due to the beverage and/or drinking soda at high temperature is released and the internal and external pressures reach equilibrium. That is, upon pressing the button 513, the channel 60 is opened to release heat, steam or hot air before the front member 51 moves from the first position to the second position, while the mouthpiece unit 30 remains in the closed folded position. Referring to the embodiment of the present utility model in the drawings, the gap 54 between the front member 51 and the rear member 52 is provided to ensure that the air discharge passage 60 is switched from the closed state to the open state before the mouthpiece unit 30 is opened. Specifically, when the user presses button 513 inwardly, shutter 515 of front member 51 first opens second end 612 of inverted-L channel 61 away from channel 60. Then, the further movement of the button 513, which is continued to be pressed, brings the rear member 52 into contact with it, and the coupling 323 and the projection 524 are disengaged, so that the mouthpiece unit 30 is switched from the closed state to the open state. The technical advantages of a preferred embodiment of the present utility model will be set forth below. Those skilled in the art will appreciate that there is no gap 54 between the front and rear members 51, 52 and that the practice of the present utility model is not affected.

As shown in fig. 11, the user continues to apply inward pressure to button 513, pushing front member 51 further inward from the neutral position. Due to the abutment of the front and rear members 51, 52, further inward advancement of the front member 51 causes the rear member 52 to move in the same direction against the second resilient portion 523 until the front and rear members 51, 52 each reach their second positions. The coupler 323 automatically pivots upward as the rear member 52 moves away from the projection 524 of the rear member 52, and the cover 40 can also be urged to pivot upward. In this case, as shown in fig. 11, the beverage channel 32 of the beverage port unit 30 automatically pivots upward, such as due to the elasticity of the channel material. The beverage passage 32 is opened to drink the beverage. That is, after continuing to press 513, the front member 51 continues to move from the neutral position to the second position, pushing the rear member 52 so that the coupling 323 is disengaged from the projection 524 of the rear member 52, and can pivot upward, thereby opening the drink port unit 30 and thus the drink passage 32, and the drink can be drunk. When the button 513 is released, the front and rear members 51, 52 will move in a direction toward the button 513 to return to their first positions, whereby the shutter 515 moves to again block the second end 612 of the exhaust passage 60 to close the passage 60. That is, after the button 513 is released, the structure is reset, closing the passage 60.

Preferably, as shown in fig. 1A and 1B, in one embodiment, the lid assembly may further include a lock 70 disposed adjacent the button 513 to lock and unlock the button 513. The lock 70 moves circumferentially along the cover 10 in the locked position and the unlocked position. In the locked position, the lock 70 is positioned to interfere with inward movement of the button 513, thereby preventing inward movement of the button 513. In the unlocked position, the lock 70 is disengaged from the movement of the button 513 such that the button 513 can be moved inwardly, opening the vent passage 60 for venting and opening the drink mouthpiece for drinking.

In summary, when the mouthpiece unit 30 is in the closed state, the front member 51 moves from the first position to the intermediate position after the button 513 is pressed. The channel 60 is first opened to release heat, steam or hot gas, but at this time the mouthpiece unit 30 remains in the closed folded position and therefore cannot drink. When the front member 51 is moved from the intermediate position towards the second gold after continued pressing 513, the rear member 52 will be pushed such that the coupling 323 is disengaged from the protrusion 524 of the rear member 52, and the beverage port unit 30 can be pivoted upwards, thereby opening the beverage port unit 30 and thus the beverage channel 32, when the beverage is consumed. In other words, when the trigger assembly 50 is switched from the first configuration to the second configuration, operation of the trigger assembly 50 causes the vent passage 60 to complete its switching from the closed state to the open state before pivoting the mouthpiece unit 30. Therefore, this operation mode can realize that heat, steam or hot air is released first and then drink the beverage when the user presses the button 513, thereby avoiding the user from being burned by the hot air sprayed from the inside of the container.

In addition, in another embodiment, the present utility model also provides a container using the cap assembly, which can be screwed to the top opening of the container body. The container may be an industrial or domestic beverage jug or other beverage can.
