Abstract

A leak-proof drinking cup has a container with an open top and a lid assembly removably attached to the container to selectively close the open top. The lid assembly includes a liquid discharge member for allowing liquid in the container to flow out of a cup. A closure member is configured to be disposed adjacent to the open top of the container when the lid assembly is attached to the container. A flexible diaphragm is movable from a sealed position to an unsealed position by a vacuum applied to the diaphragm by a user sucking the liquid discharge member. The vacuum causes the diaphragm to bend towards the container and at least partially away from the closure member, and moves the diaphragm from the sealed position to the unsealed position. The liquid discharge member and the sealing member can be formed integrally.

Description

Diaphragm for thermal insulation tumbler {LEAK RESISTANT TUMBLER FOR DIAPHRAGM THEREFOR}

Leak-proof drinking cups are often for use by small children (eg, infants, toddlers, preschool children)

Is composed. Drinking cups of these types, when they are turned-over, cause the liquid inside the cup to flow into the valve or valve assembly.

It is configured to prevent it from flowing out of the cup. Usually, the cup is open to hold and hold the liquid inside.

A container with a top and a relatively rigid cover for closing the open top of the container. Child in a cup

The spout is typically formed integrally with the rigid cover to allow drinking. The cover is releasable on the container.

Can be attached (eg, snapped or screwed).

[0003] A valve or valve assembly is typically disposed between the cover and the container, and liquid spills out of the cup for drinking.

It can be moved from a closed sealed position to an open, unsealed position to allow for. Most commonly, the valve is

It is operated by the vacuum pressure applied to the inside of the cup by the user pressing the spout. The applied vacuum pressure supports the valve.

The valve is moved to expose the passageway and allow liquid to flow out of the cup (i.e., towards the spout) or

Let it be transformed otherwise. Valves can also be operated in other ways, such as pure mechanical operation, but for young children

Vacuum pressure operation is most desirable because the only time the valve opens is when the child is drinking.

[0004] Vacuum pressure-operated drinking cups of the type just described are generally the need to ensure a tight seal and the cup is used by children.

It has certain problems associated with balancing the need to make it easier to do. The strong sealing by the valve is

It requires a large vacuum, making it difficult for the child to use. Mills requiring lower vacuum pressure to open

Valves with rods are designed to allow at least some liquid to pass through the valve, especially when dropped, shaken, shaken or impacted.

It may not be tight enough to keep it from flowing. Thus, having a low vacuum pressure actuated seal

Valves are typically prone to leaks.

Often, conventional valves are relatively small and are located under the spout. Valves of these types are often a great deal of effort to operate.

It requires air pressure, since this pressure is applied only to a relatively small area of the valve. Change

In other words, the child will have to take considerable effort to keep the valve open and get the drink, which means that the cup

Makes it less desirable.

[0006] In one conventional configuration, the valve or valve assembly may be permanently attached to the cover. During normal use of the cup

Inside, the valve or valve assembly will be contaminated with the liquid and particulates in the liquid. It can be cleaned, but the whole

It is very difficult to clean the valve/valve assembly or the entire cover. Valve/valve assembly from cover in this type of configuration

Disassembling the valve will cause destruction of the valve/valve assembly or cover. As a result, the carers of these types

It is difficult to provide a drinking cup with a clean valve/valve assembly and cover to a child when repeatedly using the drinking cup.

[0007] In other conventional configurations, the valve or valve assembly may be disassembled from the cover for cleaning. Disassembled for cleaning

Despite its ability to do so, some known valves and valve assemblies are still susceptible to contamination. Some valves and valve assemblies

Are difficult to detach and reassemble because they require correct alignment or orientation. Also, a small valve or

Parts of the valve assembly can be easily lost or pose a risk to the child if the cup is disassembled.

It does not pose a risk to young children. In addition, the adjustment of the cup (1) without including the ability to clean each of the components.

The number of separable components is minimized to make rip and reassembly relatively easy. As mentioned above, the cap

17 can be easily removed from the drinking cup 1 or fixed to it via its snap-fit connection with the cover 11. Big

The burr 11 can be removed from the container 3 or fixed to it, in the illustrated embodiment, via a screw connection with the container.

That is, the female screw 37 of the inner socket 36 of the cover 11 is engaged with the male screw 27 on the attachment collar 23 of the container 3 and

Can be disengaged from. Other shapes and structures for forming a releasable connection between cover 11 and container 3

It is captured between the containers (3). Thus, all of the components of the cup 1 can be easily removed, cleaned and reassembled.

The diaphragm 15 is snap-fastened on the closing member 13 and can be released from the snap fastening therefrom. In particular, the diaphragm

15 inserts the mounting band 85 of the closure member into the channel 76 of the diaphragm and inserts the mushroom-shaped tip 64 within the closure member.

It can be releasably coupled to the closure member 13 by insertion through the central opening 88. Diaphragm (15) sealing part

The lower member 74 of the annular rim 44 abuts the upper edge 21 of the container 3 when the cover is screwed onto the container. die

The spout 46 of the aphram 15 extends upward through an elliptical opening 49 in the cover 11. Wonju room around the spout (46)

A circumscribed rib 48 extending in the direction of the disc-shaped portion 42 to capture a portion of the cover 11 adjacent to the opening 49

Cooperate with some. The inner rib 38 of the cover 11 is received in the tapered groove 54 of the diaphragm 15.

As shown in Figure 4, the cover 11 and the diaphragm 15 is a first inner chamber 92 (broadly, "ventilation chamber")

It is limited in cooperation. More specifically, the groove 40 in the domed upper portion 39 of the cover 11, the dissipation of the diaphragm 15

The upper surface 50 of the c-shaped portion 42, the tubular stem 62, and the hollow dome 66 of the tip 64 define a first inner chamber 92.

Rock cooperation. The first inner chamber 92 is in fluid communication with the hole 41 in the cover 11, and is thus generally maintained at atmospheric pressure.

do. A second inner chamber 94 (broadly a "vacuum chamber") is defined between the closure member 13 and the diaphragm 15.

Specifically, the lower surface 52 and the concave-shaped center 60 of the diaphragm 15 and the lower base member 82 and the frame of the closing member 13

The widened member 84 cooperates and defines the second inner chamber 94. To minimize the volume of the second inner chamber 94

A portion of the diaphragm 15 is in contact with the upper base member 80 of the closure member 13. This is where the diaphragm is its secret seal

Of the cup 1 during use by minimizing the amount of air that needs to be removed from the second inner chamber 94 before being moved to

Facilitates faster priming and thus allows liquid flow to begin.

[0027] Referring now to FIGS. 4 to 7A, a young child places his lips around the spout 46 to form a seal with the spout.

Next, drink the beverage by tapping the spout by tilting the cup so that the liquid in the container (3) flows into contact with the lid assembly.

(1) It is easy to let it discharge outside. Sucking the spout 46 is part of the air from the second inner chamber 94 of the cup 1

And thus a vacuum is applied to the second inner chamber 94, so that the diaphragm 15 is removed from the sealed position (Figs. 4 and 4A).

Let it be moved to the unsealed position (Figs. 6 and 6A). More specifically, the vacuum is the disk-shaped part of the diaphragm 15

The upper surface 50 of 42 is bent downward with respect to the closure member 13, so that the volume of the second inner chamber 94 is reduced to the first volume.

(Fig. 4 and Fig. 4A) to a smaller second volume (Fig. 5 and Fig. 5A).

[0028] The upper protrusion 87 of the closing member 13 serves as a fulcrum at which the diaphragm 15 is bent around it

Do it. The upper protrusion 87 also defines a pinch point for capturing a portion of the diaphragm 15.

To do this, it works in cooperation with the inner rib 38 of the cover 11. The lower protrusion 89 of the closure member prevents the diaphragm 15 from engaging with a portion of the closure member around the central opening 88 in the closure member to form a seal with it.

It acts as a hazard stop. The distance between each of the upper protrusions 87 and the distance between each of the lower protrusions 89

It provides a path for the liquid in the group 3 to flow. The diaphragm (15) is more flexible than the closure member (13).

All. In one suitable embodiment, the diaphragm is an elastomeric polymer and has a hardness of about 75 (Type A scale).

Continuous bending of the diaphragm 15 is shown in Figures 6 and 6a, the tubular stem 62 and burr of the diaphragm

The six-shaped tip 64 moves downward relative to the closure member 13. As a result, the annular shoulder 68 of the tip 64 is

A position defining the sealing position of the diaphragm 15 in sealing contact with the closing member 13 adjacent to the shim opening 88 (Figs.

5a) the annular shoulder 68 is at least partially spaced from the portion of the closure member 13 adjacent the central opening.

(Fig. 6 and Fig. 6A), is moved to a position defining the unsealed position of the diaphragm. The annular shoulder 68 of the tip 64 is closed

When spaced apart from the member 13, there is a passage 96 allowing the liquid in the container to flow into the second inner chamber 94 of the cup 1

Is formed. That is, the liquid passes through the diaphragm 15, through the central opening 88 in the closing member 13, the second inner chamber 94

Through, it is allowed to flow into the spout 46 for drinking.

[0030] Applied by the user sucking the spout 46, to move the diaphragm 15 between its sealing position and the unsealed position

The amount of vacuum pressure required to achieve this is the area of the diaphragm (i.e., the annular shoulder 68 of the tip 64) and is in contact by the diaphragm.

Can be predetermined by changing the area of the closure member 13. In one embodiment, the diaphragm 15 is placed over its seal.

The amount of vacuum pressure required to move between the teeth and the unsealed position is less than a few hundred inches (254 centimeters).

In one suitable embodiment, it is necessary, for example, to move the diaphragm 15 between its sealed and unsealed positions.

The amount of vacuum pressure is about 47 inches (120 millimeters) of orders.

[0031] When the liquid is discharged out of the container 3 by the child, the liquid fills the reduced volume of the second inner chamber 94 of the cup 1,

The vacuum inside it is gradually reduced. The vacuum pressure in the second inner chamber 94 is brought into equilibrium with the pressure in the container 3.

When near, the elasticity of the diaphragm 15 causes it to return to the sealed position. By doing this, the diaphragm 15

The upper surface 50 of the scree-shaped part 42 is curved upward around the upper protrusion 87 of the closure member 13,

The stem 62 and tip 64 are moved jointly upward to the sealing position illustrated in FIG. 4. In this sealed position, the diaphragm

The annular shoulder 68 of the tip 64 of 15 is a liquid-tight manner with the portion of the closure member 13 adjacent to the central opening 88 in the closure member.

It engages so that it can be sealed. In addition, the tubular stem 62 and the tip 64 of the diaphragm 15 are due to the elasticity of the diaphragm 15.

Is deflected towards the sealing position.

[0032] The diaphragm 15 continues upward even after the diaphragm returns to its sealing position, as illustrated in FIGS. 7 and 7A.

The furnace is bent (ie away from the container 3). As a result, the volume of the second inner chamber 94 is smaller than the second volume (Fig. 7

And from FIG. 7A) to a larger first volume (FIGS. 4 and 4A ). This volume increase in the second inner chamber 94

Creates a vacuum pressure that expels any residual liquid from the opening 45 in the spout 46.

[0033] In the illustrated embodiment, the sealing member of the diaphragm 15 (ie, the tubular stem 62 and the tip 64) is generally aligned with the longitudinal axis of the cup 1

do. However, the sealing member is spaced apart from the longitudinal axis of the cup 1 and/or is not departing from the scope of the present invention.

Of course it can be oriented orthogonal to.

20 is a perspective view of another embodiment of the cover 111 of the cup (1). The cover 111 illustrated in FIG. 20 is the cover of this embodiment.

In FIG. 1 except that a spout shield 151 for covering the spout 46 of the diaphragm 15 is included.

It is similar to the cover 11 of FIG. 19. Accordingly, the cover 111 is suspended from the domed upper portion 139 and the upper portion.
