CN-121986058-A - Container, closure and method of manufacture

Abstract

In one aspect, a closure cap is provided that includes a base, a flip top, a disk, and a flow directing flange. The base has a central portion and a disk attachment skirt. The central portion of the base has a centrally disposed outlet. The flip cover is hingedly connected to the base and is movable between a closed position and an open position to selectively permit fluid outflow through a centrally disposed outlet of the base. The disc has a body of a disc attachment skirt securable to the base, and a single, non-centrally disposed inlet. A flow directing flange extends from the body of the disk to the base to define a fluid passage extending between the non-centrally disposed inlet and the centrally disposed outlet.

Claims (20)

1. 1. A closure cap comprising: a base having a central portion, a container attachment skirt securing the base to a container, and a disk attachment skirt, and the central portion having a centrally disposed outlet for selectively allowing fluid to flow therethrough; A flip cover hingedly connected to the base, the flip cover being movable between a closed position and an open position, the flip cover having an internal protrusion configured to be at least partially disposed within a centrally disposed outlet of the base when the flip cover is in the closed position and to be withdrawn from the centrally disposed outlet when the flip cover is in the open position; A disk having a body securable to the disk attachment skirt of the base, and a single, non-centrally disposed inlet, and A flow directing flange; wherein a fluid passage is defined by the flow directing flange, the body of the disc, and the base and extends between the non-centrally disposed inlet and the centrally disposed outlet.
2. 2. The closure cap of claim 1, wherein the disk includes the flow directing flange defining a flow path of the fluid channel that directs fluid flow from the inlet to the outlet along an entire flow length, wherein the fluid channel provides flow resistance to fluid flowing from the inlet to the outlet.
3. 3. The closure cap of claim 2, wherein the fluid directing flange includes at least one bend to increase the flow resistance of the fluid channel.
4. 4. The closure cap of claim 1, wherein the fluid directing flange surrounds the inlet and extends to a portion of the disk to be aligned with the outlet of the base.
5. 5. The closure cap of claim 1, wherein the disk includes an attachment protrusion to secure the disk to the disk attachment skirt.

14. 14. The closure cap of claim 1, wherein the disk is securable to the base in any orientation when the disk is aligned with the disk attachment skirt to fluidly connect the inlet to the outlet.
15. 15. The closure cap of claim 1, wherein the disk attachment skirt receives the disk and is positioned to support a seal in engagement with the neck of the container.
16. 16. A dispensing bottle comprising: A container body having a fluid therein, the container body having a neck, and A closure cap comprising: -a base having a central portion with a centrally disposed outlet for allowing fluid to flow therethrough when the closure cap is in an open configuration and pressure is applied to a wall of the container body, a container attachment skirt attached to the neck to secure the closure cap to the container body, and a disk attachment skirt; -a flip cover hingedly connected to the base, the flip cover being movable between a closed position and an open position, the flip cover having an internal protrusion configured to be at least partially disposed within a centrally disposed outlet of the base when the flip cover is in the closed position and to be withdrawn from the centrally disposed outlet when the flip cover is in the open position; A disc having a body of the disc attachment skirt securable to the base, and a single, non-centrally disposed inlet, and -A flow guiding flange; Wherein a fluid passage is formed by the flow directing flange, the body of the disc and the base and extends between a non-centrally disposed inlet and a centrally disposed outlet.
17. 17. The dispensing bottle of claim 16, wherein the tray comprises the flow directing flange defining a flow path of the fluid channel that directs fluid flow from the inlet to the outlet along the entire flow length.
18. 18. The dispensing bottle of claim 16, wherein the flow directing flange is sized to extend from the body of the tray to an inner surface of the base when the tray is secured to the base, the flow directing flange forming a portion of the fluid channel to direct fluid flow along a flow path between an inlet of the tray and an outlet of the base.
19. 19. The dispensing bottle of claim 16, wherein the fluid directing flange surrounds the inlet and the outlet of the base.
20. 20. The dispensing bottle of claim 16, wherein the tray includes an attachment protrusion to secure the tray to the tray attachment skirt.

Description

Container, closure and method of manufacture Cross-reference to related applications The present application claims the benefit of U.S. provisional application No. 63/542,613, filed on 5 of 10 th 2023, the entire contents of which are incorporated herein by reference. Technical Field The present disclosure relates generally to containers for fluids. More particularly, the present disclosure relates generally to a container with a closure cap. Background Some fluid containers include an outlet opening through which a consumer can dispense a desired amount of fluid from the fluid container. Such a fluid container may include a bottle and flip-top cap with an outlet opening. The consumer can open the flip-top cap and squeeze the bottle to dispense fluid from the bottle. Fluid containers occasionally experience metering and leakage problems, particularly during shipping and/or when the fluid containers are placed in a particular configuration. To address these issues, some fluid containers include flexible plastic film valves with "X" shaped slits. These membrane valves are sometimes used with inverted fluid containers that rest on their caps so that the product remains within the container through the membrane valve when not in use. One problem with such membrane valves is that they are typically made of silicone, while the other parts of the cap are typically made of another material, such as polypropylene. Closure caps constructed of multiple materials can increase manufacturing complexity and cost, and can make recycling difficult and/or impractical, making the solution unattractive for large scale use. Another problem with such membrane valves is that in some cases, product may leak through the valve when the fluid container is not in use. Furthermore, during dispensing, the product may be ejected from the outlet opening at an undesirably high velocity, increasing the risk of splattering. The high rate of product discharge also makes proper metering difficult because the product is often not adequately controlled at high rates. Another problem is that the membrane valve may resist or prevent air inflow to maintain the internal volume after dispensing, resulting in a sub-atmospheric pressure, i.e., partial vacuum, within the bottle. This may lead to wall sheeting, i.e. sagging, or other undesirable inward flexing of the container wall, which is not only visually problematic, but also functionally problematic, as it may increase the manual pressure required to dispense the product, and may result in uneven or inconsistent dispensing upon squeezing, i.e. application of manual pressure to the outside of the container.
