This application claims the benefit pf There exist some known drinking bag systems for hikers, bikers, soldiers etc. The drinking bags enable, for example, comfortable drinking during intense activity. Most of them include at least two large openings in separate locations, with respective caps, for example, one for filling and a separate one for draining the bag.

SUMMARY OF THE DISCLOSURE

Some known drinking systems may be heavy and costly, due to including many plastic parts. Some known drinking bags have elongated plastic seals which are naturally bended and therefore may prevent fluid remains from exiting the bag, even if held upside down. This may prevent complete draining of known drinking bags.

The known systems that have multiple openings for filling and draining may have resilience issues due to the many openings, which means many plastic components, which means many soldered parts that may be cause weathering and erosion to the drinking system, for example, at the soldering regions. The many plastic parts may be detached from the system and/or cause other malfunctions to the system as time passes.

Additionally, it may be hard to clean the insides of a known drinking systems, because a hand or a cleaning brush cannot be inserted. Therefore, it may be hard to keep the bag safe and healthy for drinking therefrom.

Known drinking bags are vulnerable for leaking and spilling of the fluids during the filling process, and in some products, they must be held by two hands in the process of filling.

DETAILED DESCRIPTION

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

For convenience or clarity, some elements or structures are not shown or shown only partially and/or with different perspective or from different point of views.

Reference is now made to FIG. 1, which is a schematic illustration of a drinking bag 100 in its flat state, according to some embodiments of the disclosure. Drinking bag 100 includes two layers 18 and 18a, which constitute two sides of bag 100. In FIG. 1, layer 18a is exactly behind layer 18. When bag 100 is in its flat state, for example, an area of the internal side of layer 18a can be seen through an opening 10 in layer 18. Between layers 18 and 18a, a fluid can be contained. When no fluid is contained between layers 18 and 18a, for example as presented in FIG. 1, they may be flattened against each other, for example with substantially no gap. For example, in some embodiments, three liters of fluid can be contained within bag 100, e.g. between layers 18 and 18a.

Bag 100 and/or layers 18 and 18a may include and/or be made of Thermoplastic Polyurethane (TPU).

On layer 18, drinking bag 100 may include a slantable area 12, for example facilitated by ribs 16a-16e. Ribs 16a-16e may be folding lines embedded in layer 18. For example, slantable area 12 may be a hexagonal area defined by ribs 16a-16e and by a side 16f, which may be integrated with an edge of bag 100. However, the disclosure is not limited to a hexagonal area 12, and area 12 may be of any other suitable shape and/or with any other suitable number and/or position of ribs. Slantable area 12 may include opening 10, via which fluids can be poured into and/or out from bag 100. Opening 10 may be configured to be closed by a cap. For example, opening 10 may have a screw thread formed on an external lip 11 of opening 10, configured to enable a corresponding screw cap to close opening 10. In some embodiments, opening 10 may have a diameter of about 80 millimeters, and/or may be made of Thermoplastic Polyurethane (TPU).

Ribs 16a and 16e may each be stretched between two neighboring edges of bag 100. For example, each of ribs 16a and 16e may form another triangular corner 13 between the edge of area 12 and the corresponding edges of bag 100. Corners 13 may include corresponding holes 14, which may be used for example, for hanging, attaching, and/or tying of bag 100. Further, bag 100 may include a hole 15, for example, for hanging/attaching of bag 100, in the distal edge of bag 100, e.g. the farthest edge opposite opening 10. Further, bag 100 may include a connector 17, to which a drinking pipe can be connected, for example to facilitate drinking via the pipe of fluids contained in the bag, when the bag contains fluids.

Reference is now made to FIGS. 2A and 2B, which are side view and perspective view schematic illustrations of drinking bag 100 with its filling/draining opening 10 and/or area 12 in a slanted state, according to some embodiments of the present disclosure. Slantable area 12 may be slanted along ribs 16b-16d, so that opening 10 and/or area 12 are tilted away from the rest of layer 18. When area 12 is slanted along ribs 16a-16e, fluids can be poured via opening 10 into and/or out from bag 100. Additionally, the insides of bag 100 may be cleaned by inserting a hand and/or a cleaning brush or a cloth into bag 100 via opening 10. In some embodiments, bag 100 may further include folding lines 19 from the edges of area 12 to the distal edge of bag 100, thus providing a three-dimensional structure to bag 100 when filled with fluids. This structure enables holding of bag 100, for example with one hand, and filling it with fluids. Leaking and spilling of the fluids during the filling process is less likely, due to the structure that enables firm holding of the bag at the upper region of the bag without squeezing of the bag in its middle. Accordingly, bag 100 can transform from an almost two-dimensional sheet when empty to a three-dimensional structure when filled with fluids.

Some known drinking bags have elongated plastic seals which are naturally bended and therefore may prevent fluid remains from exiting the bag, even if held upside down. This may prevent complete draining of known drinking bags. However, in drinking bag 100, hole 15 facilitates hanging of bag 100 so that opening 10 is directed downwards, so that complete draining of bag 100 from fluid is enabled. This makes any additional draining openings redundant, and thus it saves plastics of additional openings and caps. Therefore, bag 100 may be lighter in weight than other known bags, which may have multiple openings for filling and for draining the bag. Moreover, the structure of bag 100 enables better and faster ventilation and draining of bag 100 than other known drinking bags. When bag 100 is hanged with opening 10 facing downwards, for example hanged by hole 15, it may be ventilated and drained easily and quickly.

Additionally, drinking bag 100 may be more resilient than known drinking bags which have multiple openings for filling and draining. Less openings means less plastic components, which means less soldered parts that may be cause weathering and erosion to bag 100, for example at the soldering regions, and may be detached from bag 100 along time and/or cause other malfunctions to bag 100 with time. Drinking bag 100 may be cost-effective due to the small number of parts and its resiliency.

Opening 10 may be large enough so that a user can insert their hand, a cleaning brush or a cloth into the bag to clean the bag from inside, thus, keeping the bag safe and healthy for drinking therefrom.

FIG. 3 is a perspective view schematic illustration of a drinking system 300 including drinking bag 100, according to some embodiments of the present disclosure. For example, drinking system 300 includes a non-return valve 36, pipe adaptor 37 and a pipe 34. For example, non-return valve 36 is connectable to connector 17. Non-return valve 36 may include a connector enabling a pipe connection to pipe 34, for example via pipe adaptor 37, and a valve that enables fluids to flow from bag 100 to pipe 34 and prevents flow of fluids back from pipe 34 to bag 100. This is important for keeping the fluids inside bag 100 clean. Adaptor 37 may adapt the connector of valve 36, for example its diameter, for connection with pipe 34. Pipe 34 may be made of, for example, antibacterial material, Polyvinyl Chloride (PVC) and/or Polypropylene (PP). System 300 may further include a protective sleeve 35 that may insulate pipe 34, for example, from heat.

System 300 may further include a drinking spout 31, which may be connectable to the distal end of pipe 34 by a connector 33. Connector 33 may include a non-return valve that enables fluids to flow from pipe 34 to spout 31 and prevents flow of fluids back from spout 33 to pipe 34. Drinking spout 31 may include, for example, a half-turn opening mechanism, enabling opening of the spout by half-turn to drink from spout 31 by suckling, and closing spout 31 by half-turning it back. System 300 may further include a cap 32 for covering spout 31.

System 300 may include a ring 30 for mounting around lip 11/opening 10. Ring 30 may be configured to facilitate connection of system 300/bag 100 to another item for example a backpack.

System 300 may include a cap 38 for covering opening 10, for example configured to close opening 10 by screw-threading on lip 11. Cap 38 may include connector 39 that enables connection of cap 38 to bag 100, ring 30 and/or lip 11, for example by a string, so that cap 38 will not fall or get lost.
