The screen may optionally be comprised within the base, adhered to the base, or removable from the base. Features for enabling manipulation of the plate and/or screen are optionally provided.

Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to containers for cosmetic, hygiene, and other consumer products in powdered or liquid form, and particularly hermetically sealing containers. The present invention also relates to containers for condiments, food, and drinks. 
       BACKGROUND 
       [0002]    The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions. 
         [0003]    Many commercial airline passengers need or desire to carry cosmetic products or medications on board and use these formulations during the course of a flight. However, the security processes at airports have become much more stringent, particularly since the terrorist attack in New York on Sep. 11, 2001. Passengers are often only permitted to carry a limited number of small containers in which liquid material is stored. Also, security officers are typically required to direct passengers to open these containers to inspect the enclosed material and any other content. 
         [0004]    Conventional containers provide some solutions to control the release of the content material. U.S. Pat. No. 8,132,578 discloses a removable sifter disk inserted in a cosmetic package to control the release of the powdered content material. U.S. Pat. No. 8,360,259 discloses automatic opening-and-closing discharging structure in a jar. However, the prior art fails to optimally provide easily inspectable devices of preconfigured internal volume. There is a therefore a long-felt need to develop sealing containers that contain specific volumes of material and can easily be opened and resealed during security inspections. 
       SUMMARY AND OBJECTS OF THE INVENTION 
       [0005]    This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. 
         [0006]    Described embodiments provide improved sealing containers. It is an object of the present invention to provide sealing containers that may be opened and resealed and define a predetermined maximum volume of material when in a sealed state. 
         [0007]    In one embodiment, such containers include a base with an internal ledge extending from the internal surface of the base wall towards the central axis of the base, a cover with a pressure ledge on its internal surface, and a sealing plate residing upon the perimeter lip of a screen adapted to reside on the base wall internal ledge and sealing the content material when the cover and the base are coupled. A sealing of the content material is removably formed between by forcing the cover pressure ledge against the substantively impermeable sealing plate and toward a bottom of the base whereby the sealing plate is compressed against the screen perimeter lip. The sealing plate and the internal cavity of the base define a maximum volume of material that may be contained when the invented container is on a closed state. 
         [0008]    In another alternate preferred embodiment, a second screen is detachable from the base. Optional features may be included in the second screen design to allow ease of manual handling of the screen such as insertion and removal of the screen relative to the base.

         [0027]    Referring generally to the Figures and particularly to  FIG. 1A  and  FIG. 1B ,  FIG. 1A  and  FIG. 1B  illustrate a substantively hermetically sealing first container  100  according to a first embodiment. As shown in  FIG. 1A  and  FIG. 1B , the first container  100  includes three detachable components, namely a first base  102  having a first screen  104 , a first sealing plate  106 , and a first cover  108 . The first container  100  may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. 
         [0028]    As shown in  FIG. 1B , extending from an internal surface of the first base  102 , the first base  102  defines a first reservoir  110 , wherein a content material (not shown) of the first container  100  is stored. Fluids and sufficiently small particulates may enter and exit the first reservoir  110  through one or more first screen apertures  111  formed within and extending through the first screen  104 . 
         [0029]    In the first embodiment, the first base  102  has a first bottom  112  at a first end, and a first wall  114  extends from the first bottom  112 . In the first container  100 , the first wall  114  extends from the first bottom  112  at least partly along a first central axis  116 . In the first container  100 , near a second end of the first base  102  that is opposite to its first end, the first outer surface of the first wall  114  includes an attachment first section  118 . The attachment section first  118  is threaded. In first embodiment, attachment first section  118  includes a first screen  104 . 
         [0030]    As shown in  FIG. 1A  and  FIG. 1B , the first screen  104  is preferably porous, permitting the content material housed within the first reservoir  110  to pass through the first screen  104 . As further shown in  FIG. 1A  and  FIG. 1B , the first sealing plate  106  is adapted to sit upon the first screen  104  and be pressed against a first perimeter lip  120  of the first base  102  by compressive force delivered from the first cover  108  and to substantively inhibit exit of the content material from the first reservoir  110 . The first sealing plate  106  thereby forms a substantive hermetic seal with the first base  102  that substantively or completely inhibits exit of the content material from within the first container  100 . The first sealing plate  106  is adapted to rest upon the first perimeter lip  120  while receiving compressive force from the first cover  108 . As shown in  FIG. 1A  and  FIG. 1B , the first sealing plate  106  also includes a first handle  122  that may be manipulated by a user to separate the first sealing plate  106  from the first screen  104  or the first base  102 . 
         [0031]    As still further shown in  FIG. 1A  and  FIG. 1B , the first cover  108  is adapted to direct compressive force against the first sealing plate  106  and toward the first base  102  via a first cover pressuring feature  124 , and to thereby substantively seal the content material within in the reservoir  110 . The cover pressuring feature  124  is a portion of the first cover  108 . The first cover  108  further includes a first cover attachment feature  126  that is adapted to detachably couple with the first base attachment section  118 . In first embodiment, as shown in  FIGS. 1A and 1B , the first cover attachment feature  126  is tapped and is adapted to engage with the threaded attachment first section  118  of the base  102  and thereby provide compressive force from the cover pressuring feature  124  to the first screen  104  and toward the first perimeter lip  120  of the first base  102 . The first cover  108  is shaped in combination with the first base  102  to fully enclose the first sealing plate  106  when the first cover  108  and the first base  102  are coupled. 
         [0032]    It is understood that the first cover  108  is sized and shaped such that, in a first preferred embodiment of the method of the invention, a lower lip  128  of the first cover  108  is not positioned sufficiently proximate to a first side ledge  130  of the first wall of the first base  102  to enable transfer of force from the first cover  108  and to the first side ledge  130  when force is being transferred from the first cover pressuring feature  124  of the first cover  108  to the first sealing plate  106 . The first container  100  is thus shaped such that compressive force may be transferred from the first cover  108  to the first sealing plate  106  without substantive limitation by interference with the first side ledge  130  of the first base  102 . 
         [0033]    Referring now generally to the Figures and particularly to  FIGS. 2A ,  2 B and  2 C,  FIGS. 2A ,  2 B and  2 C illustrate a substantively hermetically sealing second container  200  structured according to a second embodiment. As shown in  FIGS. 2A ,  2 B and  2 C, the second container  200  includes a second base  202  having a second screen  204 , a second sealing plate  206 , and a second cover  208 . The second container  200  may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. 
         [0034]    As shown in  FIG. 2B , extending from the internal surface of the second base  202 , the second base  202  defines a second reservoir  210 , wherein the content material is stored. In the second container  200 , the second base  202  has a second bottom  212  at a first end, and a second wall  214  extends from the second bottom  212 . A second wall  214  of the second base  202  extends from the second bottom  212  at least partly along a second central axis  216 . Near a second end of the second base  202  that is opposite to its first end, the outer surface of the second wall  214  is threaded. The second wall  214  is connected with a second screen  204  of the second base  202 . Fluids and sufficiently small particulates may enter and exit the second reservoir  210  through one or more second screen apertures  211  formed within and extending through the second screen  204 . 
         [0035]    As shown in  FIGS. 2A ,  2 B and  2 C, the second screen  204  is porous, permitting the content material stored within the second reservoir  210  to pass through the second screen and out of the second base  202 . 
         [0036]    As shown in  FIGS. 2A ,  2 B and  2 C, the second sealing plate  206  is adapted to sit upon the second screen  204  and to substantively inhibit exit of the content material from the second reservoir  210 . The second sealing plate  206  forms a substantively hermetic sealing that substantively completely inhibits exit of the content material from within the second container  200 . The second sealing plate  206  is adapted to rest upon the second perimeter lip  218 . As shown in  FIGS. 2A ,  2 B and  2 C, the second sealing plate  206  also includes a second handle  220  that may be manipulated by a user to separate the second sealing plate  206  from the second screen  204 , i.e., from the second base  202 . The second sealing plate  206  includes a second holding plate  222  and a second applicator pad  224 , The second applicator pad  224  is adapted to absorb and/or adhere content material from within the second base  202 . 
         [0037]    As shown in  FIGS. 2A ,  2 B and  2 C, the second cover  208  is adapted to direct compressive force (a.) against the second sealing plate  206  and (b.) toward the second base  202  via a second cover pressuring features  226 , and thereby to substantively seal the content material within in the second reservoir  210 . The cover pressuring features  206  are each portions of the second cover  208 . The second cover  208  includes a second cover attachment feature  228  that is adapted to detachably couple with the second base  202 . The second cover attachment feature  228  is tapped and a base attachment feature  230  is threaded, wherein the second cover attachment feature  228  and the second base attachment feature  230  are adapted to engage to form a coupling of the second base  202  and the second cover  206 . The second cover  208  may thus be manually screwed down by a user about the second base attachment feature  230  and toward the second bottom  212  of the second base  202  whereby drive compressive force is directed by the second cover  208  and against the second sealing plate  206  and toward the second perimeter lip  212  of the second base  202 . 
         [0038]    The second cover  208  is shaped in combination with the second base  202  to fully enclose the second sealing plate  206  when the second cover  208  and the second base  202  are coupled. 
         [0039]    Referring generally to the Figures and particularly to  FIG. 3A ,  FIG. 3B  and  FIG. 3C ,  FIGS. 3A ,  3 B and  3 C illustrate a substantively hermetically sealing third container  300  according to third embodiment of the present invention. As shown in  FIGS. 3A ,  3 B and  3 C, the third container  300  includes a third base  302  with a third screen  304 , a third sealing plate  306 , and a third cover  308 . The third container  300  may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. 
         [0040]    As shown in  FIGS. 3A ,  3 B and  3 C, extending from an internal surface of the third base  302  defines a third reservoir  310 , wherein the content material of the third container  300  is stored. Fluids and sufficiently small particulates may pass through the third screen  304 , and thereby enter and exit the third reservoir  310 , through one or more third screen apertures  311  formed within and extending through the third screen  304 . 
         [0041]    The third base  302  has a third bottom  312  at a first end, and a third wall  314  extending from the third bottom  312 . The third wall  314  extends from the third bottom  312  at least partly along a third central axis  316 . Near a second end of the third base  302  that is opposite to its first end of the third base  302 , an outer surface of the third wall  314  includes a third attachment section  318 . The third attachment section  318  is threaded. 
         [0042]    As shown in  FIGS. 3A ,  3 B and  3 C, the third screen  304  is porous and permitting the content material in the third reservoir  310  to pass through the third screen  304  and from within the third base  302 . 
         [0043]    As shown in  FIGS. 3A ,  3 B and  3 C, the third sealing plate  306  is adapted to be pressed against the third screen  304  by compressive force delivered from the third cover  308  and to substantively inhibit exit of the content material from within the third reservoir  310 . The third sealing plate  306  is adapted to form a hermetic sealing that substantively or completely inhibits exit of the content material from within the third container  300 . 
         [0044]    It is understood that the third cover  308  is sized and shaped such that, in a third preferred embodiment of the method of the invention, a third lower lip  320  of the third wall of the third cover  308  is not positioned sufficiently proximate to a third side ledge  322  of the third base  302  to transfer force from the third cover  308  and to the third side ledge  322  when force is being transferred from the third cover  308  to the third sealing plate  306 . The third container  300  is thus shaped such that compressive force may be transferred from the third cover  308  to the third sealing plate  306  without substantive limitation due to interference between the third side ledge  322  of the third base  302  and the third cover  308 . 
         [0045]    The third sealing plate  306  is adapted to rest upon the third screen  304 . In third embodiment, as shown in  FIGS. 3A ,  3 B and  3 C, the third sealing plate  306  also includes a third handle  324  with which a user may manipulate to separate the third sealing plate  306  from the third screen  304  and the third base  302 . 
         [0046]    As shown in  FIGS. 3A ,  3 B and  3 C, the third cover  308  is adapted to direct compressive force against the third sealing plate  306  and toward the third base  302  from a cover pressuring feature  326 , and to thereby substantively seal the content material within the third reservoir  310 . The third cover pressuring feature  326  is a portion of the third cover  308 . The third cover  308  further includes a third cover tapped attachment feature  328  that is adapted to detachably couple with the threaded third attachment section  318  of the third base  302 . In the third container  300 , as shown in  FIGS. 3A ,  3 B and  3 C, the third cover attachment feature  328  is tapped. The third cover  308  is shaped in combination with the third base  302  to fully enclose and press against the third sealing plate  306  when the third cover  308  and the third base  302  are fully or substantively coupled by engagement and coupling of the third cover tapped attachment feature  328  of the third cover  308  with the threaded third attachment section  318  of the third base  302 . 
         [0047]    Referring now generally to the Figures and particularly to  FIGS. 4A and 4B ,  FIG. 4A  and  FIG. 4B  illustrate a substantively hermetically sealing container according to fourth embodiment. As shown in  FIG. 4A  and  FIG. 4B , a fourth container  400  includes a fourth base  402 , a fourth screen  404 , a fourth sealing plate  406 , and a fourth cover  408 . The fourth container  400  may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. 
         [0048]    As shown in  FIG. 4B , extending from the internal surface of the fourth base  402 , the fourth base  402  defines a fourth reservoir  410 , wherein the content material of the fourth container  400  is stored. Fluids and sufficiently small particulates may pass through the fourth screen  404 , and thereby enter and exit the fourth reservoir  410 , through one or more fourth screen apertures  411  formed within and extending through the fourth screen  404 . 
         [0049]    The fourth base  402  has a fourth bottom  412  at a first end, and a fourth wall  414  extends from the fourth bottom  412 . A fourth wall  414  of the fourth base  402  extends from the fourth bottom  412  at least partly along a fourth central axis  416 . Near a second end of the fourth base  402  that is opposite to its first end, the outer surface of the fourth wall  414  includes a fourth attachment section  418 . The fourth attachment section  418  is threaded. 
         [0050]    As shown in  FIG. 4A  and  FIG. 4B , the removable fourth screen  404  is porous, permitting the content material in the fourth reservoir  410  to pass through and to exit the fourth base  402 . As shown in  FIG. 4B , the fourth screen  404  includes a fourth sealing ledge  420  that is adapted to provide a snap fit friction fit for securely holding the fourth screen  404  within the fourth base  402 . 
         [0051]    The fourth screen  404  is detachable from and sized to fit within the fourth base  402 . The fourth screen  404  includes a fourth perimeter lip  422 . An additional fourth internal screen supporting feature  424  of the fourth base  402  extends from the internal surface of the fourth base wall  414  towards the fourth central axis  416 , and the fourth perimeter lip  422  of the fourth screen  404  is correspondingly shaped to be capable of resting on top of the fourth internal screen supporting feature  424 . The fourth internal screen supporting feature  424  is preferably a ring-shaped base internal ledge that extends towards the fourth central axis  416 . 
         [0052]    It is understood that the fourth cover  408  is sized and shaped such that, in a fourth preferred embodiment of the method of the invention, a fourth lower lip  426  of the fourth cover  408  is not positioned sufficiently proximate to a fourth side ledge  428  of the fourth base  402  to transfer force from the fourth cover  408  and to the fourth side ledge  428  when force is being transferred from the fourth cover  408  to the fourth sealing plate  406 . The fourth container  400  is thus shaped such that compressive force may be transferred from the fourth cover  408  to the fourth sealing plate  406  without substantive limitation by interference between the fourth side ledge  428  of the fourth base  402  and the fourth cover  408 . 
         [0053]    As shown in  FIG. 4A  and  FIG. 4B , the fourth sealing plate  406  is adapted to sit upon the fourth screen  404  and to substantively inhibit exit of content material from within the fourth reservoir  410 . A fourth seal is thereby generated between an external perimeter area of the fourth sealing plate  406  and an external perimeter area of the fourth screen  404  and the fourth seal is supported by a compressive force transferred from the fourth cover  408  to the fourth sealing plate  406 . The compressive force received by the fourth sealing plate  406  from the fourth cover  408  is substantively transferred through the fourth screen  404  and to the fourth base  402 . The fourth sealing plate  406  and the fourth screen  404  preferably present a substantively equivalent external diameter along a plane normal to the fourth central axis  416 . 
         [0054]    The fourth sealing plate  406  forms a substantively hermetic sealing that completely or partially inhibits exit of the content material from the fourth container  400 . The fourth sealing plate  406  is adapted to rest upon the fourth perimeter lip  422  of the fourth base  402 . 
         [0055]    As shown in  FIG. 4A  and  FIG. 4B , the fourth sealing plate  406  also includes a fourth handle  430  that enables a user to manipulate and separate the fourth sealing plate  406  from the fourth screen  404  and the fourth base  402 . 
         [0056]    As shown in  FIG. 4A  and  FIG. 4B , the fourth cover  408  is adapted to direct force against the fourth sealing plate  406  and toward the fourth base  402  via a fourth cover pressuring feature  432 , and thereby to substantively seal the content material in the fourth reservoir  410 . The fourth cover pressuring feature  432  is a portion of the fourth cover  408 . The fourth cover  408  further includes a fourth cover attachment feature  434  adapted to detachably couple with the fourth base attachment section  418 . As shown in  FIG. 4A  and  FIG. 4B , the fourth cover attachment feature  434  may be tapped. The fourth cover  408  is shaped in combination with the fourth base  402  to fully enclose the fourth sealing plate  406  when the fourth cover  408  and the fourth base  402  are coupled. The fourth cover  408  is further shaped to enclose the fourth handle  430  when the fourth cover  408  and the fourth base  402  are coupled. 
         [0057]    Referring now generally to the Figures and particularly to  FIG. 5A  and  FIG. 5B ,  FIG. 5A  and  FIG. 5B  illustrate a substantively hermetically sealing container  500  according to a fifth embodiment. As shown in  FIG. 5A  and  FIG. 5B , the fifth container  500  includes a fifth base  502 , a fifth screen  504 , a fifth sealing plate  506 , and a fifth cover  508 . The fifth container  500  may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. 
         [0058]    As shown in  FIG. 5B , extending from the fifth internal surface of the fifth base  502 , the fifth base  502  defines a fifth reservoir  510 , wherein content material of the fifth container  500  is stored. Fluids and sufficiently small particulates may pass through the fifth screen  504 , and thereby enter and exit the fifth reservoir  510 , through one or more fifth screen apertures  511  formed within and extending through the fifth screen  504 . 
         [0059]    The fifth base  502  has a fifth bottom  512  at a first end, and a fifth wall  514  that extends from the fifth bottom  512 . The fifth wall  514  extends from the fifth bottom  512  at least partly along a fifth central axis  516 . Near a second end of the fifth base  502  that is opposite to its first end, an outer surface of the fifth wall  514  includes a threaded fifth attachment section  518 . 
         [0060]    As shown in  FIG. 5A  and  FIG. 5B , the fifth screen  504  is porous, permitting the content material in the fifth reservoir  510  to pass through and from within the fifth base  502 . 
         [0061]    The fifth screen  504  is sized to fit within the fifth base  502 , and includes a fifth perimeter lip  520 . A fifth internal screen supporting feature  522  of the fifth base  502  extends from the internal surface of the fifth base wall  514  towards the fifth central axis  516 . The fifth perimeter lip  520  is correspondingly shaped to be capable of resting on top of the fifth internal screen supporting feature  522  as part of the fifth container  500 . The fifth internal screen supporting feature  522  is preferably a ring-shaped base internal ledge extending towards the fifth central axis  516 . 
         [0062]    As shown in  FIG. 5A  and  FIG. 5B , the fifth sealing plate  506  is adapted to sit upon the fifth screen  504  and to substantively inhibit exit of the content material from within the fifth reservoir  510 . The fifth sealing plate  506  is detachably pressed by the fifth cover  508  against the fifth base  502  to form a at least partially hermetic sealing that at least substantively inhibits exit of the content material from the fifth container  500 . The fifth sealing plate  506  is adapted to rest upon the fifth perimeter lip  520 . 
         [0063]    It is understood that the fifth cover  508  is sized and shaped such that, in a fifth preferred embodiment of the method of the invention, a fifth lower lip  524  of the fifth cover  508  is not positioned sufficiently proximate to a fifth side ledge  526  of the fifth base  502  to transfer force from the fifth cover  508  and to the fifth side ledge  526  when force is being transferred from the fifth cover  508  to the fifth sealing plate  506 . The fifth container  500  is thus shaped such that compressive force may be transferred from the fifth cover  508  to the fifth sealing plate  506  without substantive limitation by interference between the fifth side ledge  526  of the fifth base  502  and the fifth cover  508 . 
         [0064]    As shown in  FIG. 5A  and  FIG. 5B , the fifth sealing plate  506  also includes a fifth handle  528  that enables a user to manually separate the fifth sealing plate  506  from the fifth screen  504  and the fifth base  502 . 
         [0065]    As shown in  FIG. 5A  and  FIG. 5B , the fifth cover  508  is adapted to direct compressive force against the fifth sealing plate  506  and toward the fifth base  502  via a fifth cover pressuring feature  530 , and to thereby substantively seal the content material within the fifth reservoir  510 . The fifth cover pressuring feature  530  is a portion of the fifth cover  508 . The fifth cover  508  includes a fifth cover tapped attachment feature  532  that is adapted to detachably engage and couple with the fifth base threaded attachment section  518 . The fifth cover  508  is shaped in combination with the fifth base  502  to fully enclose the fifth sealing plate  506  when the fifth cover  508  and the fifth base  502  are coupled. The fifth cover  508  is further shaped to enclose the fifth handle  528  when the fifth cover  508  and the fifth base  502  are coupled.
