     TECHNICAL FIELD 
     The present disclosure relates to food and beverage storage containers, and in particular, to a silicone storage container having an inner insert. 
     BACKGROUND 
     Existing reusable food and beverage storage containers suffer from a number of drawbacks. For example, they may be difficult to open and close, clean, dry, stand up upright, fill, and/or seal. Such containers may also tear or break, rendering them unusable. Additionally, food and beverage storage containers may face issues of leakage from poor sealing, which impact the user experiences. 
     It is an object of the present disclosure to provide reusable food and beverage containers that can be scaled across a broad range of usage occasions and sizes, including from infant to adult hydration or feeding. Solely by way of example, the containers of the present disclosure may be used for baby food, purees, soups, smoothies, yogurt, salad dressings, beverages of any type, fruits, and snacks, whether hot or cold. Additionally, because containers of the present disclosure form enclosures with spouts and/or easy to access contents, they are ideal for “on the go” activities, where use of an open food or beverage container may otherwise lead to spilling.

In some embodiments, the inner insert  204  is compression fit within the base  202 , particularly when base  202  is formed of an elastomeric material, such as silicone. In addition, the base  202  includes one or more annular protrusions  214  extending radially outward. The annular protrusions  214  extending radially outward may engage the inner surface of the base  202  to form a compression fit, for example, in the spaces formed between the annular protrusions  212  extending radially inward of the base  202 . In some embodiments, at least one annular protrusion  214  may extend over the top edge of the opening to base  202 . Although the inner insert  204  is illustrated as having three annular protrusions  214 , in some embodiments, the inner insert  204  may have four or more annular protrusions  214 . 
     The inner insert  204  further includes a spout  216  having an inner channel  218  formed therethrough for transfer of food or a beverage from within the base  202 . As illustrated, at least a portion of the spout  216  includes male threading for engagement with female threading on the screw cap  208 , while at least a separate portion of the spout is without threading, which for example, may be placed in the mouth of a user. In some embodiments, the spout  216  could include female threading for engagement with male threading on the screw cap  208 . In other embodiments, the inner insert  204  may engage the screw cap  208  to form a click or snap tight fit, in addition to or as an alternative to threading. 
       FIGS. 8-9  illustrate the outer base cap  206 . In general, the outer base cap  206  is sized and shaped to fit tightly over the inner insert  204  and at least a portion of the base  202 . For example, the outer base cap  206  may fit tightly over the region of the base  202  where the one or more annular protrusions  214  extend radially outward from the inner insert  204  to engage the inner surface of the base  202 . In this way, the outer base cap  206  may strengthen and/or establish the compression fit between the inner insert  204  and the base  202 , thereby forming a seal. The outer base cap  206  further includes an opening  217  sized to receive the spout  216  therethrough. 
       FIGS. 10-11  illustrate the screw cap  208 . In general, the screw cap  208  is configured to fit over the spout  216  of the inner insert  204  and fix the outer base cap  206  to the inner insert  204  via a threaded engagement between the screw cap  208  and the spout  216 . In that regard, the screw cap  208  includes an inner channel  220  for receiving the spout  216 . As illustrated, at least a portion of the inner channel  220  includes female threading for engagement with the male threading on the spout  216 . In some embodiments, the inner channel  220  could include male threading for engagement with female threading on the spout  216 . In other embodiments, the screw cap  208  may engage the inner insert  204  to form a click or snap tight fit, in addition to or as an alternative to threading. 
     The screw cap  208  may optionally include one or more extensions  222  projecting downward toward the outer base cap  206  when the screw cap  208  is threaded onto the spout  216 , such that the screw cap  208  and/or the extensions  222  compress the outer base cap  206  between the inner insert  204  and the screw cap  208 , further securing the inner insert  204  and the outer base cap  206  to the base  202 . 
       FIG. 12  illustrates the spout cap  210 . In general, the spout cap  210  includes a cap portion  224  that fits over the spout  216  to selectively open and close the spout  216  and permit or prevent the passage of food or drink therethrough. The spout cap  210  further includes a ring  226  for securing the spout cap  210  to the spout  216 . The ring  226  may be placed around the spout  216  prior to threading the screw cap  208  onto the spout  216 , such that the spout cap  210  becomes fixed to the spout  216 . 
     To use the silicone storage container  200 , a user may first fill the base  202  with food or a beverage. Next, the user may fit the inner insert  204  into the opening of the base  202 , thereby enclosing base  202  to contain the food or beverage stored therein. With the inner insert  204  connected to the base  202 , the user may then slide the outer base cap  206  over the spout  216  of the inner insert  204 , followed by the ring  226  of the spout cap  210 . Next, the user may thread the screw cap  208  onto the spout  2016 , thereby fixing the base  202 , the inner insert  204 , the outer base cap  206 , the screw cap  208 , and the spout cap  210  to one another. Then, the cap portion  224  may be selectively opened and closed to permit or prevent the passage of food or drink through the spout  216 . The user may pass food or drink through the spout  216  when the cap portion  224  is removed, for example, by using the spout  216  like a drinking straw, squeezing the base  202 , and/or turning the storage container  200  upside down. After using the storage container  200 , the user may disassemble its components for washing and/or cleaning, whether by hand or in a dishwasher. 
       FIGS. 13A-B  are perspective views of an alternative base  302 , while  FIG. 13C  is an illustration of a cross-sectional view of the base  302 .  FIG. 14  is a perspective view of an alternative inner insert  304 .  FIGS. 15A-B  are perspective views of an alternative outer base cap  306 . Except as described below, the base  302 , inner insert  304 , and outer base cap  306  may be used in the storage container  200  in the same manner as described above with regard to the base  202 , the inner insert  204 , and the outer base cap  206 . 
     The base  302  of  FIGS. 13A-C  differs from the base  202  of  FIGS. 3-5  in that it also includes an inwardly projecting lip  328  configured to fit over an upper surface of the inner insert  304 . Additionally, the inwardly projecting lip  328  has a downward projecting shoulder  330  configured to fit tightly within a corresponding annular channel  332  formed in the upper surface of the inner insert  304 . Like the base  202 , the base  302  may include one or more annular protrusion  312  positioned proximate the opening of the base  302  and extending radially inward to engage the inner insert  304 . 
     The inner insert  304  of  FIG. 14  differs from the inner insert  204  of  FIGS. 6-7  primarily in that it includes an annular channel  332  formed in an upper surface of the inner insert  304 . The annular channel  332  is sized and shaped to receive the shoulder  330  of the base  302  when the inner insert  304  is inserted into the opening of the base  302 . Like the inner insert  204 , the inner insert  304  may have one or more annular protrusions that extend radially outward to engage the inner surface of the base  302 . However, as illustrated in the embodiment of  FIG. 14 , the inner insert  304  may optionally exclude the one or more annular protrusions  314 . 
     The outer base cap  306  of  FIGS. 15A-B  differs from the outer base cap  206  of  FIGS. 8-9  primarily in that the underside of the outer base cap  306  includes a plurality of ridges  334  configured to engage the inwardly projecting lip  328  of the base  302  when the outer base cap  306  is placed on the inner insert  304 . 
     In use, when the base  302 , the inner insert  304 , the outer base cap  306 , and a screw cap (for example, screw cap  208 ) are assembled as explained above in relation to the storage container  200 , the screw cap is threaded onto the spout of the inner insert  304 , such that the screw cap compresses the outer base cap  306  against the lip  328  and/or the inner insert  304 , pushing the shoulder  330  into the annular channel  332 , thereby forming a seal and preventing food or beverage in the base  302  from leaking. 
       FIGS. 16A-D  show another embodiment of a storage container of this disclosure. The storage container as shown in  FIGS. 16A-D  can be used as, for example, a food pouch for fluids or liquid foods.  FIG. 17  shows another embodiment of a storage container of this disclosure, which has the similar structure as the container of  FIG. 16A , but a larger capacity.  FIGS. 18A-H  show another embodiment of a storage container of this disclosure. The storage container as shown in FIGS.  18 A to  18 H can be used as, but not limited to, a smoothie cup.  FIGS. 19A-D  show another embodiment of a storage container of this disclosure, which can be used, but not limited to, as a sippy cup. The common structures and configurations of these embodiments are described below, with additional explanation directed to the main differences between these embodiments. 
     The storage containers have a base  410 , an inner insert  420 , and an outer base cap  430 . The interconnection of those components is similar to the base  202 , the inner insert  204 , and the outer base cap  206 , as described above for other embodiments. Specifically, the base  410  has a plurality of side walls forming an interior and an opening at an upper edge of the base  410 . The inner insert  420  is positioned in the opening of the base and sized and shaped to contact the plurality of side walls. The inner insert  420  includes a spout  421  with a channel formed therethrough. The outer base cap  430  is positioned over the inner insert  420 , and the outer base cap  430  has an opening, where the spout  421  extends through the opening. In an implementation, the base  410  may be made of or comprise an elastomer, such silicone. Further, the inner insert can be made of or comprise a rigid material. 
     Further, the base  410  includes an annular inward-facing lip  417 . The annular lip  417  contacts the inner insert  420 . A periphery of the opening of the base  410  forms an upward-facing rib  411  formed on the lip  417 , such as at the edge of the lip  417 . The rib  411  may be annular. The rib  411  includes a higher surface  413 , and the adjacent surface of the lip  417  includes a lower surface  414 . The outer base cap  430  includes a downward-facing inner skirt  433 , which may be annular and may surround the rib  411 . The inner skirt  433  of the outer base cap  430  is engaged with the lower surface  414 . The lower surface  414  may include channel to receive the inner skirt  433  of the outer base cap  430 , for example, as shown in  FIG. 18G . 
     More specifically, the base  410  may be made of an elastomer, and when the inner skirt  433  pushes downward (e.g., via tightening of screw cap  440 ), the lip  417  is elastically deformed by the inner skirt  433  (as shown in  FIGS. 16D and 18G ) to form the channel. In another embodiment, the channel can be pre-modeled, so that the channel exists even without the inner skirt&#39;s  433  pressure. The lip  417  may alternatively include another rib  416  thereon to form the channel, where the ribs  411  and  416  sandwich the inner skirt  433  (as shown in  FIGS. 16D and 18G ). The rib  411  may be, but is not limited to, approximately 1 mm in height and 2 mm in width. In one implementation, the side wall of the inner skirt  433  touches the side wall of the rib  411 . For example, the inner skirt  433  may compress the rib  411  between the inner skirt  433  and a surface of the inner insert  420 . Further, as shown in  FIG. 19C , the inner skirt  433  and the periphery of the inner insert  420  may sandwich the lip  417  to form a close and/or compression fit. 
     Further, the outer base cap  430  includes an outer skirt  432 . The outer skirt  432  compresses the walls of the base  410  in an inward direction. For example, the upper side walls of the base  410  may have an annular ramp proximate to the upper opening, such that the outer edge of the base  410  expands gradually outward from the opening of the base  410 , as shown in  FIG. 16D . In this way, the outer base cap  430  is sized and shaped to exert inward pressure on the side walls of the base  410  when the outer base cap  430  is pushed downward along with the annular ramp of the base  410 . 
     Exemplarily, the base  410  may have annular protrusion  415  positioned proximate the opening of the base  410  and extending radially inward to engage the inner insert  420 . The annular protrusion  415  of the base  410  may act as a stop and support a side wall of the inner insert  420  extending downward into the base  410 . Further, the inner insert  420  may include at least one annular protrusion  422 . The annular protrusions  422  extending radially outward may engage the inner surface of the base  410  to form a compression fit between the inner insert  420  and the outer skirt  432  of the outer base cap  430 . The base  410  correspondingly may include a channel to receive the annular protrusions  422 . The annular protrusion  422  may further sandwich the lip  417  of the base  410  with the inner skirt  433  of the inner insert  420 . 
     The storage container may further include a screw cap  440 , which serves the similar function as to the screw cap  208  of the other embodiments disclosed above. To assemble the components of the storage containers, a user inserts the inner insert  420  into the base  410 . The inner insert  420  may form a compression fit within the base  410 . The annular protrusion  422  will fit into the channel of the base  410 . The annular protrusion  415  of the base  410  may stop the inner side wall of the inner insert  420 . Then, the user covers the inner insert  420  with the outer base cap  430 . The spout  421  of the inner insert  420  goes through the opening of the outer base cap  430 . Then, the user screws the screw cap  440  onto the inner insert  420  with the threads  444  of the screw cap  440  and threads  426  of the inner insert  420 . As a user rotates the screw cap  440 , the screw cap  440  may push the outer base cap  430  downward, such that the outer base cap  430  pushes the inner skirt  433  of the outer base cap  430  downward and into compression with the lip  417 . Additionally, as the outer base cap  430  is pushed downward via rotation of the screw cap  440 , the outer skirt  432  of the outer base cap  430  is pushed downward and into compression with the walls of the base  410 , sandwiched between the outer skirt  432  and the inner insert  420 . 
     As described above for the other embodiments, the screw cap  440  may optionally include one or more extensions  441  (as shown in  FIG. 18G ) projecting downward toward the outer base cap  430  when the screw cap  440  is threaded onto the spout  421 , such that the screw cap  440  and/or the extensions  441  compress the outer base cap  430  between the inner insert  420  and the screw cap  440 , further securing the inner insert  420  and the outer base cap  430  to the base  410 . 
     Further in one embodiment, the extensions  441  may have one or more fasteners, such as a hook in a J shape, to engage with the outer base cap  430 . As shown in  FIGS. 18G and 18K , the hook has a ramp, which touches the outer base cap  430  when the screw cap  440  is screwed downward toward the inner insert  420 . The hooks of the extensions  441  will enter the opening of the outer base cap  430  and be positioned between the inner insert  420  and the outer base cap  430 . The extension  441 , therefore, forms a ledge to engage the periphery of the opening of the outer base cap  430 . The fasteners may extend both downward and radially outward from the bottom of the screw cap  440 . The bottom  445  (as shown in FIGS.  16 D and  18 K) of the screw cap  440  may therefore engage with the periphery of the opening of the outer base cap  430  because its diameter is larger than the diameter of the opening of the outer base cap  430 , so as to engage with the periphery of the opening of the outer base cap  430  and to compress the outer base cap  430  between the inner insert  420  and the screw cap  440 , further securing the inner insert  420  and the outer base cap  430  to the base  410 . 
     In one embodiment, the screw cap  440  forms a neck  442  for housing a ring  451  of the spout cap  450 . As shown in  FIGS. 18A-E , the ring  451  may be connected to different attachments. For example, the spout cap  450  may have a spoon  452  attached to the cap  453 . The cap  453  forms a channel  454  to connect the channel of the spout  421  and the bowl of the spoon  452 . Thus, the bowl can receive the food or liquid coming from the spout  421  when the cap  453  is caped onto the spout  421 . In one embodiment, the spout cap  450  may have multiple arms  455  to connect to multiple caps/attachments. For example, as shown in  FIGS. 18E  and F, the spout cap  450  has a regular cap and a cap with a spoon.  FIG. 18G  shows an enlarged cross-sectional view of the storage container of  FIG. 18E . The structure of  FIG. 18E  may apply to the storage containers of  FIGS. 18A and 18C  as well.  FIGS. 18H-K  show some common components of the storage containers of  FIGS. 18A , C, and E. In an implementation, the base  410  may be made of or comprise an elastomer, such silicone. Further, the inner insert can be made of or comprise a rigid material. 
       FIG. 18M  shows another embodiment of a storage container of this disclosure.  FIG. 18N  shows a cross-sectional view of the storage container of  FIG. 18M . The storage container of  FIG. 18M  has similar structures and functions as those of the storage containers in  FIGS. 18A , C, D described above. However, a spoon  428  with a bowl is not attached to a cap  453 , like the storage container in  FIG. 18G . Instead, the spoon  428  here is positioned next to the exist of the storage container. Specifically, the spoon  428  can be positioned at an upper terminal of the spout outlet  443 . The spoon  428  can be of a unitary construction with the screw cap  440 . Additionally, the spout  421  here is connected to a spout outlet  443 , not the spout  421  in  FIG. 18G . The screw cap  440  with the spoon  428  here can be screwed up onto the spout  421 . Additionally, the storage container in  FIGS. 18M  and N has a spout stopper  490 , including a stopper  496 , an arm  495 , and a ring  491 . The ring  491  functions and is structured similarly to ring  451 . The arm  495  extends from the ring  491 . The stopper  496  is configured at the end of the arm  495 . The stopper  496  may be perpendicular to the arm  495 . The stopper  496  is shaped and sized to seal the opening of the spout outlet  443 . It should be noted that the design of the spoon  428  and the spout stopper  490  here can be adopted to the other embodiments, such as the storage containers as shown in  FIGS. 18A , C, &amp; E, such that the spoon  428  can extend from the spout  421  in  FIGS. 18A , C, &amp; E. 
     In another embodiment, the storage container as shown in  FIG. 18O  has a spout cap  450 , including a cap  453 . A stopper  456  is situated in the bottom of the cap  453 . The stopper  456  is sized and shaped to seal the channel of the spout  421 . Additionally, the spout  421  of the inner insert  421  has a curvature  429  next to the periphery of the opening of the screw cap  440 . The curvature  429  creates a substantially seamless engagement between the top surface  446  of the screw cap  440  and the side wall of the spout  421 . Further, the bottom  445  of the screw cap  440  touches the periphery of the opening of the outer base cap  430  and thereby pushes the outer base cap  430  downwardly when the screw cap  440  is rotated in a downward direction. 
     In another embodiment, the storage containers as shown in  FIGS. 19A , B, C, and E have an inner insert  420  with a spout  421 . The spout  421  in this embodiment serves as a part of a larger spout formed in connection with the screw cap  440 . Here, the screw cap  440  includes a spout outlet  443  in fluid connection with the spout  421 . The spout outlet  443  has multiple smaller openings as compared to the embodiments above. This implementation of the spout  421  and the spout outlet  443  can also be applied to the embodiments described above. The storage container further includes a valve  460 . The valve  460  is shaped and sized to attach to the channel of the inner insert  420 , and can be used to control the flow of the food or liquid in the channel of the spout  421 , such that food or liquid may flow out of the storage container in response to a positive threshold pressure in the storage container, or a negative threshold pressure in the spout  421 . The channel of the inner insert  420  may have an inwardly projecting lip  427  (as shown in  FIGS. 19C  and F) to fix the valve  460  in the channel of the inner insert  420 . The inwardly projecting lip  427  may form a hole (as shown in  FIG. 19H ) to receive the valve  460 . Correspondingly, the valve  460  may include a neck, and the edge of the hole of the lip  427  engages with the neck of the valve  460 . 
       FIG. 19G  shows an enlarged view of the storage container of  FIG. 19E , focused on the valve  460 . The valve  460  in  FIGS. 19A  to H may be similar. The valve  460  may be shaped like a duckbill. Specifically, the lip  427  may include one or more channels  463 . The one or more channels  463  allow contents stored in the storage container to flow to the spout outlet  443 , when the valve  460  is opened. The one or more channels  463  may be formed on the inwardly projecting lip  427  of the inner insert  420 , and the one or more channels  463  may be arranged evenly around the hole defined by the lip  427  of the inner insert  420 . Additionally, the valve  460  includes an annular lip  461 . The annular lip  461  may be shaped like an umbrella and sized to cover the one or more channels  463 . The annular lip  461  therefore prevents the stored content in the container from flowing out unless there is a positive threshold pressure in the storage container, or a negative threshold pressure in the spout outlet  443 . The valve  460 , including the annular lip  461 , may comprise an elastomer; therefore, when the pressure in the storage container is sufficient, the lip  461  is deformed to allow the stored contents to flow out from the one or more channels  463 . When the pressure disappears, the shape and position of the annular lip  461  restore to cover the one or more channels  463 . The valve  460  may also include leaflets  462 , which may open, due to the negative pressure in the storage container, to allow air, residual food, or liquid in the spout outlet  443  to flow back to the container via the channel in the middle of the valve  460  when the leaflets  462  are opened. Allowing air to flow back into the container also permits the container to return to its original shape, if squeezed to force contents contained therein through the spout outlet  443 . 
     As shown in  FIG. 19D , which is an exploded view of the storage container of  FIG. 19A , the screw cap  440  here includes a spout outlet  443 . The spout outlet  443  is connected to the spout  421  of the inner insert  420  and receives the food or liquid from the channel of the spout  421 . The lower portion of the screw cap  440  has a similar configuration as to the other screw caps  440  described above. In an implementation, the base  410  may be made of or comprise an elastomer, such silicone. Further, the inner insert can be made of or comprise a rigid material. As shown in  FIGS. 19A and 19E , the storage container may further include at least one handle  470  attached to the base  410 . Additionally, as shown in  FIG. 19  E, the storage container may further include notch  418  on the base  410 . The inner side wall of the handle  470  and the side wall of the notch  418  define an opening.  FIGS. 20A-B  show another embodiment of a storage container of this disclosure. The storage container here can be used as a popsicle cup. The container includes a base  410  and an inner insert  420 . The base  410  has a plurality of side walls forming an interior and an opening at an upper edge of the base  410 . The inner insert  420  is positioned in the opening of the base  410  and sized and shaped to contact the plurality of side walls. Exemplarily, the base  410  may have annular protrusion  415  positioned proximate the opening of the base  410  and extending radially inward to engage the inner insert  420 . 
     Further, the inner insert  420  may include at least one annular protrusion  422 . The annular protrusions  422  extending radially outward may engage the inner surface of the base  410  to form a compression fit, for example, proximate the opening of the base  410 . The base  410  may correspondingly have an annular channel to receive the annular protrusions  422 . 
     The inner insert  420  forms an opening to allow a stick  480  to extend through the opening. The stick  480  may form multiple holes on one end to serve as an anchor for forming a popsicle. The stick  480  may have an intermediate portion  481  having a width larger that the adjacent portions, as shown in  FIG. 20C . The intermediate portion  481  is configured to engage with the periphery of the opening of the inner insert  420  directly or indirectly. Optionally, the stick may include a sealing ring  482  around the intermediate portion  481 . The sealing ring  482  may help the container prevent leakage. In an implementation, the base  410  may be made of or comprise an elastomer, such silicone. Further, the inner insert can be made of or comprise a rigid material. 
       FIGS. 20D-E  show another embodiment of a storage container of this disclosure. The storage container here can be used as a popsicle cup as well. The structures and functions of the storage container in  FIGS. 20D-E  are similar to the storage container as shown in  FIGS. 20A-B . However, the top layer of the inner insert  420  here covers the upward-facing rib  411  formed next to the periphery of the opening of the base  410 . The top layer of the inner insert  420  extends outwardly beyond the rib  411 . Further, the intermediate portion  481  of the stick  480  is thicker than the top layer of the inner insert  420  around the intermediate portion  481  of the stick  480 . As described above, the ring  482  is embedded between the intermediate portion  481  and the inner insert  420  when the stick  480  is assembled with the inner insert  420 . Further, the depth of the engagement of the ring  482  with the intermediate portion  481  is larger than the depth of the engagement of the ring  482  with the layer of the inner insert  420 . Specifically, the intermediate portion  481  and the periphery of the opening of inner insert  420  may form channels  484 ,  485  to receive the ring  482 . The depth of the channel  484  of the intermediate portion  481  of the stick  480  is larger than the depth of the channel  485  of the inner insert  420  as shown in  FIG. 20E . 
       FIGS. 21A-B  show still another embodiment of a storage container of this disclosure. The storage container includes a base  410 , an inner insert  420 , and an outer base cap  430 . The base  410  has a plurality of side walls forming an interior and an opening at an upper edge of the base  410 . The inner insert  420  is positioned in the opening of the base  410 , and it is sized and shaped to contact the plurality of side walls. The outer base cap  430  is positioned over the inner insert  420 . The inner insert  420  may comprise an annular channel  425  to receive an inward-facing annular lip  417  of the base  410 . The inner insert  420  here also has at least one annular protrusion  422 . The annular protrusions  422  extends radially outward and may engage the inner surface of the base  410  to form a compression fit. The base  410  may correspondingly have a channel to receive the annular protrusions  422 . The base  410  similarly may include an annular protrusion  415 , which serves the similar function as to the annular protrusion  415  of the other embodiments. 
       FIGS. 21C-D  show the inner insert  420  and the outer base cap  430  of the storage container in  FIGS. 21A-B . The inner insert  420  may include an ear  423 . The ear  423  may touch the side wall of the base  410 . Optionally, the ear  423  may include a fastener, such as a button  424 . The button  424  is configured to be fastened with the button hole  431  on the outer base cap  430 . The inner insert  420  here also has at least one annular protrusion  422 . In an implementation, the base  410  may be made of or comprise an elastomer, such silicone. Further, the inner insert can be made of or comprise a rigid material. 
       FIGS. 21E to 21H  show another embodiment of a storage container of this disclosure. The storage container of  FIGS. 21E to 21H  is constructed and functions similar to the storage container in  FIGS. 21A-B . Additionally, there are some main differences as follows. Exemplarily, the outer base cap  430  here may have a curved extension  434 , where a button hole situated. 
     Further, as shown in  FIG. 21F , the opening of the base  410  may be not contoured with the periphery of the inner insert  420  before the base  410  and the inner insert  420  are assembled together. For example, the opening of the base  410  may have a width larger than the width of the inner insert  420  along a first direction D 1 , while the opening of the base  410  may have a width smaller than the width of the inner insert  420  along a second direction D 2  perpendicular to the first direction D 1  before the base  410  and the inner insert  420  are assembled together. Alternatively, the opening of the base  410  may have a width smaller than the width of the inner insert along both a first direction D 1  and a second direction D 2  perpendicular to the first direction D 1  before the base  410  and the inner insert  420  are assembled together. The width of the base  410  in the first direction D 1  may, however, be identical or different from the width of the base  410  in the second direction D 2 . Thus, the elastomeric base  410  and the rigid of the inner insert  420  do not fit together unless the base  410  is stretched and deformed to fit around the inner insert  420 . Here and as in the other embodiments of storage containers described herein, the inner insert  420  may have a rigidity larger than the rigidity of the base  410 . Exemplarily, the base  410  may include an elastomer, such as silicone. The inner insert  420  may be formed of a rigid plastic, such as polypropylene. Therefore, to assemble the base  410  and the inner insert  420  together, the base  410  may be stretched and/or deformed to fit the contour of the inner insert  420 . The deformation may create a tighter fit between the base  410  and the inner insert  420 . Again, this mechanism and selection of material can be adopted by the other storage containers described in this disclosure, such as the storage containers in  FIGS. 1 to 21 . 
     It should be noted that the size and shape of the storage containers as disclosed herein may vary without departing from the scope of this disclosure, for example, as shown in  FIGS. 16A and 17 . 
       FIG. 22A  is a perspective view of another embodiment of a storage container of this disclosure. The storage container in  FIG. 22A  has similar structures with the storage container as shown in  FIGS. 18M and 18N . The description below addresses the main differences of the storage container in  FIG. 22A . 
     Referring to  FIGS. 22A-F , the storage container  100  here includes a stopper ring  447  configured to receives the stopper  496 . When the stopper  496  is not attached to the outlet  622  of the screw cap  440  (e.g., when the storage container  100  is in use), the stopper ring  447  can receive and position the stopper  496  so that it does not interfere with use of the spoon  428 . The stopper ring  447  can be positioned on the screw cap  440 . Alternatively, the stopper ring  447  may be positioned on the outer base cap  430 . 
     Further the attachment  457  as shown in  FIG. 22D  may have a different design as compared to the design in  FIGS. 18M and 18N . Specifically, the attachment  457  includes a first ring  492  positionable about the neck  442  of the screw cap  440 . Additionally, the attachment  457  may include a second ring  494 . The ring  494  may be smaller than the ring  492  (e.g. having a smaller diameter). A gap may be formed between the ring  492  and ring  494 . When assembled with the screw cap  440  and the ring  492  may be received by the neck  442 . The ring  494  may be positioned inside the screw cap  440  and be surrounded by a bottom wall  448  of the screw cap  440 . A connecting wall  449  of the inner insert  440  may be situated within the gap between the ring  492  and the ring  494 . The ring  494  may be situated between the screw cap  440  and a ledge  621  of the inner insert  420 . Additionally, the ring  492  and the ring  494  may be connected together by one or more bridges  496 ,  497 . The bridges  467 ,  468  may be aligned with the arm  495 . When assembled, the bridges  467 ,  468  can be situated in one or more gaps  465  of the bottom wall  448  of the screw cap  440 . The second ring  497  can increase the stability of the connection between the attachment  457  and the screw cap  440 . Further, the bridges  467 ,  468  may prevent the rotation of the attachment  457 , given that the bridges  467 ,  468  are located in the gaps  465 . 
       FIG. 23A  is a perspective view of another embodiment of a storage container  100  of this disclosure.  FIG. 23B  is a cross-sectional view of the storage container  100  of  FIG. 23A , and  FIGS. 23C-E  show different components of the storage container  100  of  FIG. 23A . The storage container  100  in  FIG. 23A  has similar structures with the storage container  100  as shown in  FIGS. 19E and 19F . The description below addresses the main differences of the storage container  100  in  FIG. 23A . 
     As explained above with reference to  FIGS. 19E and 19F , the attachment  457  in  FIG. 23C  may have a different design as compared to the design in  FIGS. 19E and 19F . Specifically, the attachment  457  may include the ring  492  positionable to the neck  442 . Additionally, the attachment  457  may include the ring  494 . The ring  494  may be smaller than the ring  492  (e.g. having a smaller diameter). A gap may be formed between the ring  492  and ring  494 . When assembled with the screw cap  440 , the ring  492  may be received by the neck  442 . The ring  494  may be positioned inside the screw cap  440  and be surrounded by a bottom wall  448  of the screw cap  440 . A connecting wall  449  may be situated within the gap between the ring  492  and the ring  494 . The ring  494  may be situated between the screw cap  440  and a ledge  621  of the spout cap  420 . Additionally, the ring  492  and the ring  494  may be connected together by one or more bridges  467 ,  468 . The bridges  467 ,  468  may be aligned with arm  495 . When assembled, the bridges  467 ,  468  can be situated in one or more gaps  465  of the bottom wall  448  of the screw cap  440 . Further, the base  410  here may, optionally, include one or more handle  470  like the other embodiments disclosed a 
     Additionally, the storage container  100  may include a barrier  464  to prevent or reduce potential choking hazards, especially for children. The barrier  464  may be situated on the top of the spout  421 . For example, the spout  421  may have an annular protrusion configured to support the barrier  464 . The barrier  464  may block articles larger than a particular size. For example, the opening of the barrier  464  may be smaller than the valve  460 , and thereby, it can block the valve  460  if the valve  460  is detached from the spout  421 . Further, the barrier  464  can prevent access to the valve  460  from the outside of the storage container  100 . In some embodiments, the barrier  464  may include one or more crossbars to effectively block articles from passing therethrough. 
       FIG. 24A  is a perspective view of another embodiment of a storage container  100  of this disclosure.  FIG. 24B  is a cross-sectional view of the storage container  100  of  FIG. 24A .  FIGS. 24C-D  show different components of the storage container  100  of  FIG. 24A . The storage container  100  in  FIG. 24A  can be used as a popsicle cup to make two or more popsicles in one batch. The base  410  can be filed with liquid for freeing to create the popsicles. The storage container  100  has a base  410  similar to the base  410  in the other embodiments described above, and the base  410  here may be compatible for use with other components, such as the inner inserts and base caps, of those storage containers  100   s . The storage container  100  here may have a first inner insert  510 , a second inner insert  520 , and a third inner insert  530 . The first inner insert  510 , the second inner insert  520 , and the third inner insert  530  are all removably positionable in the base  410 . The second inner insert  520  may be configured as a divider to divide the base  410  into two or more volumes, with side walls  525  contacting the side walls of the base  410 . Each of the first inner insert  510  and the third inner insert  530  may include one or more covers  511 ,  531  and one or more sticks  512 ,  532 . The covers  511  and  531  are shaped and sized to mate with a protrusion  415  of the base  410  and a ledge  521  of the second inner insert  520 . For example, a part (such as its ledge) of the covers  511  and  531  is positionable on the ledge  521  and the protrusion  415 . The inner insert  520  may have a ridge  523  positioned between the covers  511  and  531  and in contact with the covers  511  and  531 . The covers  511 ,  531  and the ridge  523  may form a compression fit within the side wall of the base  410 . The inner insert  520  further includes ledges  522 , which are positionable below the protrusion  415 , to secure the inner insert  520  within the base  410 . The side walls  524  of the inner insert  520  facing the sticks  512 ,  532  may be curved inwardly to define at least a part of a popsicle formed in the base  410 . The side walls  525  of the inner insert  520  between the two side walls  524  may be curved outwardly for engagement with the side wall of the base  410 . The inner insert  520  may be a hollow structure. The storage container  100  in  FIG. 24A  may be used as a popsicle cup. 
     Like the storage container  100  illustrated in  FIG. 21F , the storage container  100  of  FIG. 24A  has a similar design to create a compression fit between the base  410  and the inner inserts  510 ,  520 ,  530  when positioned therein. Specifically, as shown in  FIG. 24E , when the inner inserts  510 ,  520 ,  530  is separated from the base  410 , the width W 1  of the inner insert  520  may be larger than the width W 2  of the base  410 . Likewise, the width of the inner inserts  510 ,  530  may be larger than corresponding widths of the base  410 . Alternatively, or additionally, the length L 1  of the inner inserts  510 ,  520 ,  530  in combination may be shorter than the length L 2  of the base  410 . Thus, when the set of the inner inserts  510 ,  520 ,  530  is positioned in the base  410 , the base  410  (which may comprise an elastomer) may deformed to create a compression fit. 
     The description above discloses multiple embodiments of storage container  100   s  with different intended usage applications. In one implementation, any base  410  can be compatible for use with the different components, such as the inner inserts  420  and outer base caps  430  disclosed herein. Therefore, a consumer can use a same base  410  (or set of bases) to combine with different types of inner inserts and base caps  430  depending on the desired usage application. For example, a consumer can purchase a base  410  compatible for use with different inner inserts  420  and base caps  430  for different applications, such as a drinking bottle, a snack pouch, or a popsicle cup. Conveniently, this design also allows the same base  410  to be used for users over a range of different ages and applications, for example, beginning with an infant sippy cup, then as a snack cup or smoothie cup for toddlers, then as a popsicle cup or drinking bottle for youth and/or adults. 
     Having the design introduced in this disclosure, the structure and material improve the performance of the storage containers toward the goal of leakproof, airtight, freezer/dishwasher/milk warmer/microwave safe, BPA/PVC/Latex free storage containers.
