Patent Description:
Endoscopy procedures that use typical endoscopes for both therapeutic and diagnostic cases usually have some common functionalities available to an operator. One of the common functionalities includes the ability to insufflate a patient by passing a fluid, such as air or carbon dioxide, through the endoscope in a controlled manner into a target luminal space. Another of the common functionalities includes the ability to flush water across the imaging lens to clear the field of view. Yet another of the common functionalities includes the ability to irrigate the lumen to clean surfaces and aid in flushing/suctioning debris during a procedure. Oftentimes, these common functionalities, among others, are facilitated by one or more fluid containers and/or fluid sources. For example, an air pump or carbon dioxide source for insufflation, a water bottle for lens cleaning, and/or a sterile water bottle for irrigation. In some cases, a hybrid tubing set may be used for both lens cleaning and irrigation from a sterile water bottle. The one or more fluid containers and/or sources, each potentially with a different size and/or configuration, must be attached to the tubing set of the endoscope. It is with all of the above considerations in mind that the improvements of the present disclosure may be useful. <CIT> discloses an endoscope system and water bottle cap assembly for an endoscopic device, wherein the endoscope system includes an endoscope device and means for directing a fluid adjacent a tip of the endoscope device. The fluid directing means includes a fluid container for containing the fluid, the container including an inlet and an outlet. The system further includes separating means for separating liquid or solid particles from gas entering the container through the inlet.

The Detailed Description will be better understood in conjunction with the accompanying drawings, wherein like reference characters represent like elements, as follows:.

The following Detailed Description should be read with reference to the drawings, which depict illustrative embodiments. It is to be understood that the present disclosure is not limited to the particular embodiments described, as such may vary. All apparatuses and systems and methods discussed herein are examples of apparatuses and/or systems and/or methods implemented in accordance with one or more principles of the present disclosure. Each example of an embodiment is provided by way of explanation and is not the only way to implement these principles but are merely examples. Thus, references to elements or structures or features in the drawings must be appreciated as references to examples of embodiments of the present disclosure, and should not be understood as limiting the present disclosure to the specific elements, structures, or features illustrated. Other examples of manners of implementing the disclosed principles will occur to a person of ordinary skill in the art upon reading the present disclosure. It will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the scope of the present subject matter. Thus, it is intended that the present subject matter covers such modifications and variations as come within the scope of the appended claims and their equivalents.

The described technologies are generally directed to fluid container enclosures configured to be coupled to a fluid container, for example, to seal the fluid container while enabling access to the contents of the fluid container, such as from an endoscopic system via a tubing set. A fluid container may be or may include a bottle or reservoir (see for example, reservoir <NUM>). The fluid container enclosures may be configured as a cap, lid, or other enclosure component capable of sealing a fluid container. In some embodiments, the fluid container enclosures may include openings, lumens, holes, or other elements capable of allowing tubing access to the contents of the fluid container while maintaining a seal. Fluid container enclosures according to some embodiments are configured to operate with fluid containers of various properties, such as size, port or neck configuration, thread configuration, and/or the like. Accordingly, fluid container enclosures according to some embodiments may operate as universal enclosures that are able to be used with a wide array of fluid container configurations, including fluid containers made by different manufacturers and fluid containers having different shapes, sizes, neck configurations, thread configurations, and/or the like.

Some challenges in coupling with a fluid container and gaining access to the contents of the fluid container may include having a fluid container enclosure that is compatible with the fluid container. For example, a fluid container enclosure may include a screw cap with one or more tubes extending therethrough. In such examples, the screw cap may couple to corresponding threads on a neck of the fluid container with the one or more tubes extending therethrough enabling the endoscopic system to access the contents of the fluid container. However, there are many different types of fluid container manufacturers that offer different fluid container designs. Further, manufacturers may offer different fluid container designs and/or periodically change or update fluid container designs. For instance, manufacturers may offer designs with different thread patterns or neck sizes around the world based on regional preferences or demands. This presents a challenge for manufacturers of tubing sets by requiring them to offer multiple products with customized fluid container enclosures for each design. Further, product acquisition and stocking by health care facilities is complicated by necessitating that they ensure that tubing sets have a fluid container enclosure that is compatible with an available fluid container.

In addition, irrigation and lens cleaning may be employed in all endoscopic procedures by connecting a tubing set to a reservoir fluid container, such as a water or irrigation bottle. Some bottles are re-usable and require cleaning and to prevent patient infection, while some bottles are single use sterile containers. Bottle thread designs vary from manufacturer to manufacturer, requiring various configurations of conventional caps to fit the many models of bottle. Accordingly, there is a desire for a cap configuration capable of attaching to the many different types of bottles with minimal configuration changes. Moreover, some endoscopic procedures choose to use alternative methods of insufflation and forward-facing irrigation, which require alternative connections to the <NUM>-day use caps in conjunction with specified sterile water bottles. This increases the number of potential configurations required and can result in the wrong type in the operation room, thereby increasing procedure times. Accordingly, there is a also a need for a fluid container cap that incorporates both insufflation and irrigation options into one cap and tubing set.

Accordingly, various embodiments of the present disclosure include fluid container enclosures that widen the scope of compatibility to a variety of different fluid container designs and/or functionality types, such as insufflation and irrigation. In many embodiments, one or more fluid container enclosures of the present disclosure may provide an efficient, safe, and effective way to couple with and gain access to the contents of a multitude of fluid container designs. Enabling fluid container enclosures to be compatible with different fluid container designs allows manufacturers of tubing sets to offer products that are more adaptable. Further, enabling fluid container enclosures to be compatible with different fluid container designs can simplify product acquisition and stocking by health care facilities.

For example, enclosure systems according to some embodiments may be used with a wide variety of fluid container port, opening, or neck dimensions, such as an opening diameter and/or thread configuration (for instance, Glass Packaging Institute (GPI) thread finish, "H" dimension, thread distance, thread dimensions, and/or the like), thread pitch, outer diameter (OD) of port or neck (OD port), OD of threads (OD thread), thread width, and/or the like. In addition, enclosure systems according to some embodiments may be used on fluid containers made by various manufacturers.

For example, in some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having an opening size (e.g., neck OD, not including threads) of about <NUM>, about <NUM>, about <NUM>, about <NUM> mm about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints). In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having an opening size (e.g., neck OD, not including threads) of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM> to about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints).

In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having a total opening size (e.g., neck OD including threads) of about <NUM>, about <NUM>, about <NUM>, about <NUM> mm about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints). In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having a total opening size (e.g., neck OD including threads) of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints).

In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having a thread width of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints). In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having a thread width of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints).

In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having a thread pitch of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints). In some embodiments, an enclosure system may include a single cap that is capable of being installed on containers having a thread pitch of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints).

In some embodiments, an enclosure system may include a single cap that is capable of being installed on a fluid container having a GPI thread finish of <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and any value or range between any two of these values (including endpoints).

In various embodiments, an enclosure system may include a single cap that is capable of being installed on different types of fluid container ports or necks. For example, a cap of an enclosure system according to some embodiments may be installed on (and form a seal with) fluid container ports with different dimensions. In some embodiments, an enclosure system may include a single cap that is capable of being installed on a plurality of fluid container ports having a OD thread difference (Δ OD thread) (i.e., the difference between an OD thread of the smallest OD thread port and the largest OD thread port) of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints). In various embodiments, an enclosure system may include a single cap that is capable of being installed on a plurality of fluid container ports having a OD port difference (Δ OD port) (i.e., the difference between an OD port of the port with the smallest OD port and the port with the largest OD port) of about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints).

The described embodiments may provide additional advantages that would be known to those of skill in the art.

The term "exemplary" is used in the sense of "example," rather than "ideal. " Although endoscopes and endoscopic systems are referenced herein, reference to endoscopes, endoscopic systems, or endoscopy should not be construed as limiting the possible applications of the disclosed aspects. For example, the disclosed aspects may be used in conjunction with duodenoscopes, bronchoscopes, ureteroscopes, colonoscopes, catheters, diagnostic or therapeutic tools or devices, or other types of medical devices or systems.

Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form to facilitate a description thereof. The intention is to cover all modification, equivalents, and alternatives within the scope of the claims.

With reference to <FIG>, an exemplary endoscope <NUM> and system <NUM> is depicted that may comprise an elongated shaft 100a that is inserted into a patient. A light source <NUM> feeds illumination light to a distal portion 100b of the endoscope <NUM>, which may house an imager (e.g., CCD or CMOS imager) (not shown). The light source <NUM> (e.g., lamp) is housed in a video processing unit <NUM> that processes signals that are input from the imager and outputs processed video signals to a video monitor (not shown) for viewing. The video processing unit <NUM> also serves as a component of an air/water feed circuit by housing a pressurizing pump <NUM>, such as an air feed pump, in the unit.

The endoscope shaft 100a may include a distal tip 100c provided at the distal portion 100b of the shaft 100a and a flexible bending portion <NUM> proximal to the distal tip 100c. The flexible bending portion <NUM> may include an articulation joint (not shown) to assist with steering the distal tip 100c. On an end face 100d of the distal tip of the endoscope <NUM> is a gas/lens wash nozzle <NUM> for supplying gas to insufflate the interior of the patient at the treatment area and for supplying water to wash a lens covering the imager. An irrigation opening <NUM> in the end face 100d supplies irrigation fluid to the treatment area of the patient. Illumination windows (not shown) that convey illumination light to the treatment area, and an opening <NUM> to a working channel <NUM> extending along the shaft 100a for passing tools to the treatment area, also may be included on the face 100d of the distal tip 100c. The working channel <NUM> extends along the shaft 100a to a proximal channel opening <NUM> positioned distal to an operating handle <NUM> of the endoscope <NUM>. A biopsy valve <NUM> may be utilized to seal the channel opening <NUM> against unwanted fluid egress.

The operating handle <NUM> may be provided with knobs <NUM> for providing remote <NUM>-way steering of the distal tip via wires connected to the articulation joint in the bendable flexible portion <NUM> (e.g., one knob controls up-down steering and another knob control for left-right steering). A plurality of video switches <NUM> for remotely operating the video processing unit <NUM> may be arranged on a proximal end side of the handle <NUM>. In addition, the handle is provided with dual valve wells <NUM> that receive a gas/water valve <NUM> for operating an insufflating gas and lens water feed operation. A gas supply line 240a and a lens wash supply line 245a run distally from the gas/water valve <NUM> along the shaft 100a and converge at the distal tip 100c proximal to the gas/wash nozzle <NUM> (<FIG>). The other valve well <NUM> receives a suction valve <NUM> for operating a suction operation. A suction supply line 250a runs distally from the suction valve <NUM> along the shaft 100a to a junction point in fluid communication with the working channel <NUM> of the endoscope <NUM>.

The operating handle <NUM> is electrically and fluidly connected to the video processing unit <NUM>, via a flexible umbilical <NUM> and connector portion <NUM> extending therebetween. The flexible umbilical <NUM> has a gas (e.g., air or CO2) feed line 240b, a lens wash feed line 245b, a suction feed line 250b, an irrigation feed line 255b, a light guide (not shown), and an electrical signal cable. The connector portion <NUM> when plugged into the video processing unit <NUM> connects the light source <NUM> in the video processing unit with the light guide. The light guide runs along the umbilical <NUM> and the length of the endoscope shaft 100a to transmit light to the distal tip 100c of the endoscope <NUM>. The connector portion <NUM> when plugged into the video processing unit <NUM> also connects the air pump <NUM> to the gas feed line 240b in the umbilical <NUM>.

A water reservoir <NUM> (e.g., water bottle) is fluidly connected to the endoscope <NUM> through the connector portion <NUM> and the umbilical <NUM>. A length of gas supply tubing 240c passes from one end positioned in an air gap <NUM> between the top <NUM> (e.g., bottle cap or enclosure) of the reservoir <NUM> and the remaining water <NUM> in the reservoir to a detachable gas/lens wash connection <NUM> on the outside of the connector portion <NUM>. The gas feed line 240b from the umbilical <NUM> branches in the connector portion <NUM> to fluidly communicate with the gas supply tubing 240c at the detachable gas/lens wash connection <NUM>, as well as the air pump <NUM>. A length of lens wash tubing 245c, with one end positioned at the bottom of the reservoir <NUM>, passes through the top (e.g., a cap or enclosure) <NUM> of the reservoir <NUM> to the same detachable connection <NUM> as the gas supply tubing 240c on the connector portion <NUM>. In other embodiments, the connections may be separate and/or separated from each other. The connector portion <NUM> also has a detachable irrigation connection <NUM> for irrigation supply tubing (not shown) running from a source of irrigation water (not shown) to the irrigation feed line 255b in the umbilical <NUM>. In some embodiments, irrigation water is supplied via a pump (e.g., peristaltic pump) from a water source independent (not shown) from the water reservoir <NUM>. In other embodiments, the irrigation supply tubing and lens wash tubing 245c may source water from the same reservoir. The connector portion <NUM> may also include a detachable suction connection <NUM> for suction feed line 250b and suction supply line 250a fluidly connecting a vacuum source (e.g., hospital house suction) (not shown) to the umbilical <NUM> and endoscope <NUM>.

The gas feed line 240b and lens wash feed line 245b are fluidly connected to the valve well <NUM> for the gas/water valve <NUM> and configured such that operation of the gas/water valve in the well controls supply of gas or lens wash to the distal tip 100c of the endoscope <NUM>. The suction feed line 250b is fluidly connected to the valve well <NUM> for the suction valve <NUM> and configured such that operation of the suction valve in the well controls suction applied to the working channel <NUM> of the endoscope <NUM>.

Referring to <FIG>, an exemplary operation of an endoscopic system <NUM>, including an endoscope such as endoscope <NUM> above, is explained. Air from the air pump <NUM> in the video processing unit <NUM> is flowed through the connection portion <NUM> and branched to the gas/water valve <NUM> on the operating handle <NUM> through the gas feed line 240b in the umbilical <NUM>, as well as through the gas supply tubing 240c to the water reservoir <NUM> via the connection <NUM> on the connector portion <NUM>. When the gas/water valve <NUM> is in a neutral position, without the user's finger on the valve, air is allowed to flow out of the valve to atmosphere. In a first position, the user's finger is used to block the vent to atmosphere. Gas is allowed to flow from the valve <NUM> down the gas supply line 240a and out the distal tip 100c of the endoscope <NUM> in order to, for example, insufflate the treatment area of the patient. When the gas/water valve <NUM> is pressed downward to a second position, gas is blocked from exiting the valve, allowing pressure of the air passing from the air pump <NUM> to rise in the water reservoir <NUM>. Pressurizing the water source forces water out of the lens wash tubing 245c, through the connector portion <NUM>, umbilical <NUM>, through the gas/water valve <NUM> and down the lens wash supply line 245a, converging with the gas supply line 240a prior to exiting the distal tip 100c of the endoscope <NUM> via the gas/lens wash nozzle <NUM>. Air pump pressure may be calibrated to provide lens wash water at a relatively low flow rate compared to the supply of irrigation water.

The volume of the flow rate of the lens wash is governed by gas pressure in the water reservoir <NUM>. When gas pressure begins to drop in the water reservoir <NUM>, as water is pushed out of the reservoir <NUM> through the lens wash tubing 245c, the air pump <NUM> replaces lost air supply in the reservoir <NUM> to maintain a substantially constant pressure, which in turn provides for a substantially constant lens wash flow rate. In some embodiments, a filter (not shown) may be placed in the path of the gas supply tubing 240c to filter-out undesired contaminants or particulates from passing into the water reservoir <NUM>. In some embodiments, outflow check valves or other <NUM>-way valve configurations (not shown) may be placed in the path of the lens wash supply tubing to help prevent water from back-flowing into the reservoir <NUM> after the water has passed the valve.

A relatively higher flow rate compared to lens wash is typically required for irrigation water, since a primary use is to clear the treatment area in the patient of debris that obstructs the user's field of view. Irrigation is typically achieved with the use of a pump (e.g., peristaltic pump), as described. In embodiments with an independent water source for irrigation, tubing placed in the bottom of a water source is passed through the top of the water source and threaded through the head on the upstream side of the pump. Tubing on the downstream side of the pump 255c is connected to the irrigation feed line 255b in the umbilical <NUM> and the irrigation supply line 255a endoscope <NUM> via the irrigation connection <NUM> on the connector portion <NUM>. When irrigation water is required, fluid is pumped from the water source by operating the irrigation pump, such as by depressing a footswitch (not shown), and flows through the irrigation connection <NUM>, through the irrigation feed line 255b in the umbilical, and down the irrigation supply line in the shaft 100a of the endoscope to the distal tip 100c. In order to equalize the pressure in the water source as water is pumped out of the irrigation supply tubing, an air vent (not shown) may be included in the top (e.g., a cap or enclosure) <NUM> of the water reservoir <NUM>. The vent allows atmospheric air into the water source preventing negative pressure build-up in the water source, which could create a vacuum that suctions undesired matter from the patient back through the endoscope toward the water source. In some embodiments, outflow check valves or other <NUM>-way valve configurations (not shown), similar to the lens wash tubing 245c, may be placed in the path of the irrigation supply tubing to help prevent back-flow into the reservoir after water has passed the valve.

<FIG> illustrates various aspects of a tubing assembly for an endoscopic system according to the present disclosure. As shown in <FIG>, a tubing assembly <NUM> may include an enclosure system <NUM> that includes a cap <NUM> coupled to a tubing assembly <NUM>. In some embodiments, tubing assembly <NUM> may be integrated into cap <NUM>. In various embodiments, cap <NUM> may be configured as a multi-threaded cap capable of attaching to numerous types of fluid containers (e.g., sterile irrigation bottles) with minimal or even no configurations required. Tubing assembly <NUM> may include a plurality of tubing, such as a gas supply tubing, lens wash supply tubing, and/or irrigation supply tubing.

Accordingly, in some embodiments, cap <NUM> may include all possible connections (e.g., water, air, CO2, irrigation, insufflation, and/or the like) used during a procedure as well as multi-threaded device(s) to accommodate the variance in characteristics of fluid containers (e.g., neck characteristics, thread characteristics, and/or the like). Cap <NUM> may include multiple connection ports (see, for example, <FIG>) in order to include multiple options into one irrigation cap - tube assembly (an extra boss may be required for a CO2 connection option). Cap <NUM> may be designed to include or interface with configurations for specific scope processors and other functions, for example, to accommodate a large and small peristaltic options.

In various embodiments, tubing <NUM> may be coupled to tubing <NUM> via ports in cap <NUM> (see, for example, <FIG>). Tubing <NUM> may be coupled to an endoscope, for example, via air/water channel <NUM> and/or gas channel <NUM>. Tubing <NUM> may be configured as a disposable tubing kit for one-time use during an endoscopic procedure.

At least a portion of tubing <NUM> may be arranged within a fluid container coupled to cap <NUM> during the endoscopic procedure. Tubing <NUM> may be configured the same or substantially similar to tubing 240c, 245c, and/or 255c described in the present disclosure. In some embodiments, tubing <NUM> may include a large irrigation tubing <NUM>, for example, to facilitate peristaltic irrigation functions.

<FIG> illustrates a top perspective view depicting various aspects of an enclosure system according to the present disclosure. As shown in <FIG>, enclosure system <NUM> may include a cap <NUM> having ports <NUM>-<NUM>. In various embodiments, ports <NUM> may be used to connect tubing for various functions, such as air, water, CO2, irrigation, insufflation, scope-specific processor connections, and/or the like. For example, port <NUM> may be configured as an irrigation connection, for instance, for a large irrigation tube designed for peristaltic irrigation. Port <NUM> may be for scope-specific processor connections and port <NUM> may be configured to receive a CO2 insufflation tube. In various embodiments, external tubing (i.e., tubing that is not port of cap <NUM>, for instance tubing <NUM>) may be connected or bonded to cap <NUM> via ports through external bonding or internal bonding (see, for example, <FIG> and <FIG>, respectively).

Although a large irrigation port, a CO2 port, and a scope-specific processor connections port are used in the example depicted in <FIG>, embodiments are not so limited, as enclosure systems may include more or less ports configured to interface with different functions in accordance with the present disclosure.

<FIG> illustrates a partial side sectional view depicting various aspects of an external-coupling embodiment of the enclosure system of <FIG>. In an external-coupling embodiment, external tubing sets 601a, 601b may be coupled or bonded to cap <NUM> by pressing tubing 601a, 601b over corresponding ports or nipples <NUM>-<NUM> protruding from cap <NUM> to force tubing 601a, 601b in direction A toward cap <NUM>. In some embodiments, tubing 601a, 601b may be forced toward cap <NUM> over ports <NUM>-<NUM> until blocked by an object, such as a surface of cap (e.g., until shouldered against the lowest point possible on an upper surface of cap <NUM>). The coupling or bonding occurs between an internal surface or diameter of tubing 601a, 601b and an external surface or diameter of corresponding ports <NUM>-<NUM>.

<FIG> illustrates a side sectional view depicting various aspects of an internal-coupling embodiment of the enclosure system of <FIG>. In some embodiments, tubing sets 601a, 601b, may be coupled or bonded to cap <NUM> internally, for example, to support pressurized operation. Internal-coupling may include a vertical-wall coupling embodiment and/or a shoulder coupling embodiment. In a vertical-wall coupling embodiment, tubing 601b extends through an opening <NUM> in cap <NUM>, for example, through a port cavity, lumen, or other structure <NUM>, and the external wall <NUM> of tubing 601b engages an internal surface <NUM> of cap <NUM> to couple or bond tubing 601b to cap <NUM>. Accordingly, tubing may pass through cap <NUM> and bond to the vertical walls of the cap <NUM>. In a shoulder-coupling embodiment, tubing 601a may pass through opening <NUM> and be forced over port <NUM> until tubing 601a contacts shoulder <NUM> of port <NUM>. A coupling or bond may occur between tubing 601a and vertical wall <NUM>, outer walls of port <NUM>, and/or upper surface of shoulder <NUM>.

<FIG> illustrates a side sectional view depicting various aspects of an enclosure system according to the present disclosure. As shown in <FIG>, an enclosure system <NUM> may include a cap <NUM> configured to be installed on a port (e.g., a neck) of a fluid container, such as fluid container <NUM> of the present disclosure. In some embodiments, cap <NUM> may include a plurality of modules, carriers, carriages, or other interface elements arranged within an internal cavity of cap <NUM> (e.g., an interior space formed within cap710) that may be configured to engage fluid container ports of different characteristics, including different thread configurations (for instance, size, OD, pitch, spacing, and/or the like) and/or different port dimensions (for instance, OD).

In various embodiments, cap <NUM> may include a primary (large-dimension or carrier ring) carriage <NUM> arranged within the internal cavity of cap <NUM> and configured to engage larger dimensioned fluid container ports and a secondary (small-dimension or floating ring) carriage <NUM> that may be arranged within an internal cavity of primary carriage <NUM> (e.g., an inner space arranged within primary carriage <NUM>; "internal primary cavity") to engage smaller dimensioned fluid container ports. In some embodiments, larger/smaller dimensions may be or may include OD port, OD thread, and/or the like.

In some embodiments, the dimension difference between primary carriage <NUM> and secondary carriage <NUM> may be about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, and any value or range between any two of these values (including endpoints). In some embodiments, the dimension difference between primary carriage <NUM> and secondary carriage <NUM> may be about <NUM> (difference in thread outer diameter outside of United States (US) (OUS)), about <NUM> (difference in OUS-US OD thread), and any value or range between any two of these values (including endpoints) (see, for example, Table <NUM>, below).

Primary carriage <NUM> may include external threads <NUM> configured to engage threads <NUM> of cap <NUM>, for example, to couple primary carriage <NUM> to cap <NUM>. In some embodiments, primary carriage <NUM> may be rotated within cap to move in one of directions B and C via the engagement between threads <NUM> and <NUM>. In various embodiments, primary carriage <NUM> may include internal threads <NUM> (e.g., primary internal threads) configured to engage corresponding threads on a fluid container port (not shown; see, for example, <FIG>).

Secondary carriage <NUM> may include internal threads <NUM> (e.g., secondary internal threads) configured to engage corresponding threads on a fluid container port (i.e., smaller thread OD than for primary carriage <NUM>). In some embodiments, secondary carriage <NUM> may be biased in direction B by a spring (or other biasing member) <NUM> arranged within cap <NUM>. Accordingly, in the absence of a force on secondary carriage <NUM> in direction C, secondary carriage <NUM> may be arranged within space <NUM>, for example, with a lower surface <NUM> of secondary carriage <NUM> resting against shoulder <NUM> of primary carriage <NUM>. In some embodiments, spring <NUM> may operate to control rebound of secondary carriage <NUM> out of (or down (i.e., direction B) through) primary carriage <NUM> for fluid container ports that require secondary carriage <NUM> to move for installing a fluid container port in cap <NUM> and/or sealing via sealing element <NUM>.

In various embodiments, one or more sealing elements may be arranged within cap <NUM> to form a seal with fluid container ports installed within cap. For example, a sealing element or surface <NUM>, such as an o-ring, washer, or a layer of sealing material, may be arranged on/about or coupled to internal surface <NUM>, for example, a bottom surface of port cavity <NUM>. In this manner, when a fluid container port is installed within cap, an upper surface of the port may form a seal (e.g., a compression seal) with sealing element <NUM>. In some embodiments, sealing element <NUM> may be formed of various materials, such as a polymer, silicone, a thermoplastic elastomer, variations thereof, combinations thereof, and/or the like.

In general, secondary carriage <NUM> may be configured for smaller OD thread connections (see, for example, <FIG>) and may translate out of the larger OD ports and OD threads (see, for example, <FIG>). In various embodiments, primary carriage <NUM> may be threaded via threads <NUM> so that when secondary carriage <NUM> reaches the extent of its translation and the fluid container port requires more room to reach sealing surface <NUM>, primary carriage threads <NUM> allow primary carriage <NUM> to ride up (i.e., direction C) into cap <NUM> (see, for example, <FIG>).

In some embodiments, a torque control element (not shown) may be used to control the torque required for primary carriage <NUM> to thread into and out of cap <NUM>. In some embodiments, the torque control element may include an o-ring gland and/or o-ring to control the threading torque of primary carriage <NUM> within cap <NUM>. For example, an o-ring may be arranged above threaded sections (for example, <NUM>, <NUM>, and/or <NUM>) and below the internal ceiling of cap <NUM>, for instance, to provide interference or resistance to rotation for primary carriage <NUM>.

<FIG> illustrates an exploded perspective view depicting various aspects of an enclosure system with fluid container port according to the present disclosure. Enclosure system <NUM> may be configured to receive a fluid container port <NUM> having threads <NUM> (see for example, <FIG> and <FIG>). As shown in <FIG>, one or more guide protrusions, ridges, or bosses <NUM> may be arranged on an outer surface of secondary carriage <NUM>. Guide bosses <NUM> may be configured to be seated or otherwise arranged within corresponding guide cavities or slots <NUM> within primary carriage <NUM>. <FIG> illustrates a side sectional view depicting various aspects of a primary carriage element of the enclosure system of <FIG> showing, among other things, guide slots <NUM> within primary carriage <NUM>. <FIG> illustrates a side perspective view depicting various aspects of a secondary carriage element of the enclosure system of <FIG> showing, among other things, guide bosses <NUM> arranged around the outside of secondary carriage <NUM>. Guide bosses <NUM> may engage guide slots <NUM> to prevent rotational movement (i.e., spinning) of primary carriage <NUM> and/or secondary carriage <NUM> within cap <NUM>. In this manner, rotation of cap <NUM> may occur (for example, to thread cap <NUM> further down on primary carriage <NUM>) without causing corresponding rotation of primary carriage <NUM> and/or secondary carriage <NUM>, which would prevent threading of cap <NUM> in direction B (toward fluid container).

<FIG> illustrates various aspects of example fluid container ports that may be installed within a single enclosure system according to the present disclosure. <FIG> depicts port <NUM> (i.e., a neck of a fluid container) with threads <NUM>, <FIG> depicts port <NUM> with threads <NUM>, and <FIG> depicts port <NUM> with threads <NUM>, each with dimensions as indicated in Table <NUM>:.

Although bottles <NUM>, <NUM>, and <NUM> having dimensions specified in Table <NUM> are used in some examples in the present disclosure, embodiments are not so limited, as enclosure systems may be configured to accommodate a plurality of fluid container ports with different dimensions depending on the particular design and configuration of the enclosure system and components thereof.

<FIG> illustrates various aspects of enclosure systems installed on example fluid container ports that may be installed within enclosure systems according to the present disclosure. Referring to <FIG>, therein is depicted port <NUM> installed within cap <NUM>. Port <NUM> is a larger-dimensioned port; accordingly, port <NUM> is installed within primary carriage <NUM>. To install cap <NUM> on port <NUM>, cap <NUM> may be pushed down onto port <NUM> in direction D until threads <NUM> contact threads <NUM>, preventing further movement of cap <NUM> in direction D. At this stage, port <NUM> may be threaded into cap <NUM> via engagement of threads <NUM> and threads <NUM>, causing movement of cap <NUM> down port <NUM> in direction D (and port <NUM> up into cap <NUM> in direction E). As port <NUM> moves up into cap <NUM>, an upper surface <NUM> of port <NUM> may engage a bottom surface <NUM> of secondary carriage <NUM> within space <NUM>, forcing secondary carriage <NUM> in direction E until upper surface <NUM> engages sealing element <NUM>, forming a seal between port <NUM> and cap <NUM>.

Referring to <FIG>, therein is depicted port <NUM> installed within cap <NUM>. As shown in <FIG>, in some configurations of port <NUM>, an interference may arise between flange <NUM> and a bottom surface <NUM> of primary carrier that may cause a gap within space <NUM> between surface <NUM> and sealing element <NUM>. Accordingly, in some embodiments, threads (not shown) may be incorporated on the inside of cap <NUM> and externally on primary carrier <NUM> to allow cap <NUM> to thread down (i.e., direction E) after flange <NUM> has made contact with cap <NUM>. Accordingly, in some embodiments, cap <NUM> may include a set of secondary threads that may allow cap <NUM> to be threaded down primary carriage <NUM> after a port (e.g., port <NUM>) has engaged with cap to prevent the port with sealing with sealing element <NUM>, for example, to allow primary the port to engage sealing element <NUM>. For example, referring to <FIG>, cap <NUM> may include secondary threads <NUM> that may engage threads <NUM> to allow cap <NUM> to be threaded down primary carriage <NUM> to reduce or even eliminate any gap between surface <NUM> and sealing element <NUM>.

Referring to <FIG>, therein is depicted port <NUM> installed within cap <NUM>. Port <NUM> is a larger-dimensioned port; accordingly, port <NUM> is installed within primary carriage <NUM>. To install cap <NUM> on port <NUM>, cap <NUM> may be pushed down onto port <NUM> in direction D until threads <NUM> contact threads <NUM>, preventing further movement of cap <NUM> in direction D. At this stage, port <NUM> may be threaded into cap <NUM> via engagement of threads <NUM> and threads <NUM>, causing movement of cap <NUM> down port <NUM> in direction D (and port <NUM> up into cap <NUM> in direction E), for example, until an upper surface of port <NUM> engages sealing element <NUM> (or other internal surface) of cap <NUM>. In some embodiments, a portion of port <NUM> may engage a portion of secondary carriage <NUM> while traveling in direction E, pushing secondary carriage <NUM> up within cap <NUM>.

Referring to <FIG>, therein is depicted port <NUM> installed within cap <NUM>. Port <NUM> is a smaller-dimensioned port; accordingly, port <NUM> is installed within secondary carriage <NUM>. Prior to installation, secondary carriage <NUM> is biased in direction D via spring <NUM> such that bottom surface <NUM> of secondary carriage <NUM> is resting against upper surface <NUM> of primary carriage <NUM>. To install cap <NUM> on port <NUM>, cap <NUM> may be pushed down onto port <NUM> in direction D until threads <NUM> contact threads <NUM>, preventing further movement of cap <NUM> in direction D. At this stage, port <NUM> may be threaded into cap <NUM> via engagement of threads <NUM> and threads <NUM>, causing movement of cap <NUM> down port <NUM> in direction D (and port <NUM> up into cap <NUM> in direction E), for example, until an upper surface of port <NUM> engages sealing element <NUM> (or other internal surface) of cap <NUM>.

<FIG> illustrates a side sectional view depicting various aspects of a clip multi-carriage enclosure system installed on a fluid container port according to the present disclosure. As shown in <FIG>, an enclosure system <NUM> may include a cap <NUM> having at least one port <NUM> for connecting tubing (e.g., air, water, CO2) to a fluid container (not shown). In various embodiments, cap <NUM> may include a primary (or large-dimension) carriage <NUM> configured to engage larger dimensioned fluid container ports and a secondary (or small-dimension) carriage <NUM> to engage smaller dimensioned fluid container ports. In some embodiments, primary carriage <NUM> and/or secondary carriage <NUM> may operate the same or substantially similar to primary carriage <NUM> and/or secondary carriage <NUM>, respectively.

Primary carriage <NUM> may include internal threads <NUM> for engaging corresponding threads of larger-dimensioned fluid container ports. Secondary carriage <NUM> may include internal threads <NUM> for engaging corresponding threads of smaller-dimensioned fluid container ports (e.g., port <NUM>).

In some embodiments, secondary carriage <NUM> is nested inside primary carriage <NUM>. In various embodiments, primary carriage <NUM> may be clipped into outer cap <NUM> and may be threaded (via threads <NUM>) for larger bottle types. Secondary carriage <NUM> may be biased by spring (or other biasing member) <NUM> and can ride up/down (direction G/direction F) in primary carriage <NUM> to float out of the way of large bottle types. Secondary carriage <NUM> may be threaded (via threads <NUM>) for smaller bottle types. The connection between primary carriage <NUM> and secondary carriage <NUM> may be sprung to prevent free float of the secondary carriage <NUM>.

Primary carriage <NUM> may be snap-fitted into cap <NUM>. For example, primary carriage <NUM> may be installed in cap <NUM> by forcing primary carriage up (direction G) into cap <NUM> until flange, boss, or other surface <NUM> of primary carriage <NUM> passes and becomes seated or otherwise engaged with shoulder <NUM> of cap <NUM>. Vertical walls of cap <NUM> may flex outward to allow primary carriage <NUM> to be pushed up (direction F) into cap until flange <NUM> passes shoulder <NUM>, retaining primary carriage <NUM> within cap <NUM>.

Port <NUM> may include threads <NUM> configured to engage threads <NUM>, allowing cap <NUM> to be rotated to cause port <NUM> to ride up (direction F) within secondary carriage <NUM> until port <NUM> engages internal surface <NUM> of cap <NUM> (for example, to form a seal with a sealing element associated with surface <NUM>).

In some embodiments, spring <NUM> may be put into an extended position, pushing secondary carriage <NUM> (e.g., operating as a floating ring) down allowing the smaller diameter bottle thread (i.e., <NUM>) to be readily accepted. Small thread diameter <NUM> has clearance through the larger threads (e.g., <NUM>) in the primary carriage <NUM> (e.g., operating as a carrier ring). In various embodiments, primary carriage <NUM> may be fixed to the cap (via various methods known to those of skill in the art, such as adhesives, molding, and/or the like), allowing secondary carriage <NUM> to move in the up/down (Z direction) axis. Rotating cap <NUM> may operate to drive the port and secondary carriage <NUM> towards seal <NUM> until sufficient contact is made to form an adequate seal (e.g., prevent fluid leakage). The embodiment depicted in <FIG> may include guide slots in primary carriage <NUM> (not shown, see <FIG>) of accepting guide bosses (not shown, see <FIG>) on secondary carriage <NUM> while preventing rotation of secondary carriage <NUM> during cap <NUM> attachment.

<FIG> illustrates a side sectional view depicting various aspects of a stepped thread enclosure system installed on a fluid container port according to the present disclosure. As shown in <FIG>, an enclosure system <NUM> may include a cap <NUM> having a plurality of sets of internal threads configured for different fluid container port configurations. For example, cap <NUM> may have threads <NUM> for larger-dimensioned ports and threads <NUM> for smaller-dimension ports.

For example, port <NUM> may be a larger-dimensioned port having threads <NUM> (for example, the same or similar to port <NUM>) configured to engage threads <NUM>. In another example, port <NUM> may be a larger-dimensioned port having threads <NUM> (for example, the same or similar to port <NUM>) configured to engage threads <NUM>. In the example depicted in <FIG>, two (half) ports <NUM>, <NUM> are shown installed within cap <NUM>. However, this is for illustrated purposes only as only one port (such as one of <NUM> or <NUM>) may be installed within cap <NUM> at a time.

To install a port, cap <NUM> may be pressed down over the port until one of threads <NUM> or <NUM> engages corresponding threads of the port (such as <NUM> and <NUM> or <NUM> for <NUM>). Then, cap <NUM> may be rotated to install cap <NUM> on the port.

<FIG> illustrates a side perspective view depicting various aspects of a flexible ring enclosure system according to the present disclosure. As shown in <FIG>, a cap <NUM> may be or may include a flexible component configured as a single, custom, deep, threaded design capable of flexing to allow cap <NUM> to flex around the OD port and/or OD thread of the port (not shown) of a fluid container when interference begins to occur as cap <NUM> is being pressed down onto the port. Graph <NUM> depicts flexible cap <NUM> in a deformed condition, depicting forces <NUM> and corresponding force information <NUM>. Graph <NUM> depicts flexible cap <NUM> in a stressed condition, depicting forces <NUM> and corresponding force information <NUM>.

In some embodiments, internal threads <NUM> may be sufficiently deep enough and the material sufficiently flexible enough to allow for sealing forces (e.g., to form a water-tight, gas-tight, hermetic, or other seal) between cap <NUM> and port.

In some embodiments, as cap <NUM> is pressed down on a port having an OD thread and/or OD port that is larger than am inner diameter (ID) of cap <NUM>, cap <NUM> may flex to increase ID to allow outer threads on port to engage threads <NUM>. At this stage, cap <NUM> may be threaded onto port, with cap <NUM> flexing to allow port to ride up through port via engagement of the port threads with threads <NUM>.

<FIG> illustrates a side perspective view depicting various aspects of a slotted ring enclosure system according to the present disclosure. As shown in <FIG>, a cap or portion of a cap <NUM> may include internal threads <NUM> arranged on a skirt <NUM> having slots <NUM> configured to form legs <NUM> in skirt <NUM>. In some embodiments, component <NUM> may be a cap; in other embodiments, component <NUM> may be a cap insert (for example, the same or similar to primary carriage <NUM>, secondary carriage <NUM>, insert <NUM> of <FIG>), and/or the like.

Skirt <NUM> may be configured to flex radially in an outward direction. In some embodiments, skirt <NUM> may be biased to flex outward. Ring <NUM> may be arranged around skirt <NUM>, for instance, held within groove <NUM>. Ring <NUM> may be formed of various rigid materials, such as metal, polymer, variations thereof, combinations thereof, and/or the like. Ring <NUM> may be flexible <NUM>, for instance, due to gap <NUM>. In some embodiments, ring <NUM> may be biased to hold skirt <NUM> inward (i.e., against outward bias of skirt <NUM>).

In some embodiments, as cap <NUM> is pressed down on a port having an OD thread and/or OD port that is larger than an ID of skirt <NUM>, skirt <NUM> may flex to increase ID to allow outer threads on port to engage threads <NUM>. At this stage, cap <NUM> may be threaded onto port, with skirt <NUM> and ring <NUM> flexing to allow port to ride up through port via engagement of the port threads with threads <NUM>. In some embodiments, ring <NUM> may be configured to prevent over-extension of skirt <NUM> (for instance, due to forcing cap <NUM> on a fluid container port that is too large to be accommodated by cap <NUM>.

Accordingly, cap <NUM> may be configured as a flexible custom, deep, threaded component that allows allowing multiple fluid container port connections.

<FIG> illustrates a side sectional view depicting various aspects of a dual-threaded insert enclosure system according to the present disclosure. As shown in <FIG>, an enclosure system <NUM> may include a cap <NUM> having ports <NUM> may be configured to receive an insert <NUM>. Insert <NUM> may be dual-threaded, with external threads <NUM> configured to engage internal threads <NUM> of cap <NUM>. Internal threads <NUM> may be configured to engage corresponding threads of a fluid container port (not shown). <FIG> illustrates a side perspective view of dual-threaded insert <NUM> depicted in <FIG>.

Insert <NUM> may be threaded up into cap <NUM> until upper surface <NUM> contacts internal surface <NUM>. Cap <NUM> may be pushed onto a port such that threads <NUM> contact corresponding threads of the port, then cap <NUM> may be rotated onto port, causing cap <NUM> to move down onto port via the engagement between threads <NUM> and the port threads. Threads <NUM> and <NUM> may be threaded (or reversed threaded) such that threading of cap <NUM> (via threads <NUM>) onto the port does not cause insert <NUM> to be unthreaded from threads <NUM> of cap <NUM>.

In some embodiments, cap <NUM> may receive inserts <NUM> of various inner dimensions to accept various types of bottles. For example, cap <NUM> may receive inserts with a standard or standard range of OD port, OD threads, and/or other port characteristics so that inserts <NUM> may be coupled to cap <NUM>. The inner dimension (e.g., ID port, ID threads, and/or the like) may be different to accommodate various bottle types. In this manner, a single cap <NUM> may be installed on different bottle types through the use of inserts <NUM> of differing internal dimensions.
