     Packaging container  10  includes a base section  20  having a chamber  25  defined by a peripheral wall  30 . Peripheral wall  30  forms the perimeter of chamber  25  and is collectively formed by spaced-apart inner wall segment  30   a  and an outer wall segment  30   b  adjoined by a top ledge  30   c.    
     In order to facilitate a secure closure of packaging container  10 , outer wall segment  30   b  includes at least one depression  40  formed therein. At least one aperture  42  is formed within depression  40  for engaging an inwardly protruding section formed on a cover section  50 , as will be discussed in detail below. A plurality of apertures  42  may be included in some embodiments. At least one additional aperture  43 , which aligns with aperture  42 , may also be formed within inner wall segment  30   a  of peripheral wall  30 . Top ledge  30   c  also includes a scalloped area  44  formed therein adjacent to depression  40  formed within outer wall segment  30   b  for facilitating release of cover section  50 . Further, a laterally extending flange  45  extends from outer wall segment  30   b  as show in  FIG. 1A . 
     Packaging container  10  also includes a cover section  50  pivotally coupled to base section  20  at a hinge  52 . Cover section  50  is configured to pivot about hinge  52  between an open state and a closed state. In particular, cover section  50  includes a top surface having a recessed face  77  and side wall portion  54 , which is collectively formed by first and second lateral walls  55 ,  57  and first and second end walls  58 ,  59 .

First lateral wall  155  includes at least one inwardly protruding section  165  shaped to correspond with depression  140  formed within outer wall segment  130   b  of peripheral wall  130 . In addition, a post  167  projects from inwardly protruding section  165 . Post  167  is adapted to engage corresponding aperture  142 . A peripheral flange  170  extends horizontally from a perimeter of cover section  150  such that, when packaging container  110  is in a closed position, peripheral flange  170  abuts flange  145  of base section  120 . Peripheral flange  170  includes a cut out area  171  adjacent to inwardly protruding section  165 , as will be discussed below. 
     As discussed with respect to the embodiment of  FIGS. 1A-2E , in order to provide a container that is secure when closed, but is also easy to open by a user, packaging container  110  includes features that allows for easy one-hand opening. In particular, with reference to  FIG. 3B , laterally extending flange  145  is deformable such that when flange  145  depressed in a region  175  adjacent to depression  140  of outer wall segment  130   b , outer wall segment  130   b  moves inwardly, and thereby releasing post  167  from apertures  142  and/or  143  and opening packaging container  110 . Peripheral flange  170  of cover section  150  includes a cut out area  171  at inwardly protruding section  165  of side wall portion  154 , such as to provide unobstructed access for depressing deformable flange  145  of base section  120  for opening packaging container  110  when in a closed position. A scalloped area  144  is also formed adjacent to depression  140  formed within outer wall segment  130   b  for facilitating release of cover section  150 , as shown in  FIG. 3A . 
     An additional embodiment is shown in  FIGS. 4A-4D , wherein a packaging container  210  includes a base portion  220  and a separate cover portion  250 .  FIGS. 4A-4D  illustrate assembled, bottom, cover, and assembled top views of packaging container  210 . In order to facilitate a secure closure of packaging container  210 , base portion  220  includes at least one depression  240  formed therein. An aperture  242  is formed within depression  240  for engaging a projection formed on cover section  250 , as will be discussed in detail below. At least one additional aperture, which aligns with aperture  242 , may also be formed within base portion  220 . A laterally extending flange  245  is also provided. Cover section  250  includes a side wall portion  254  having at least one inwardly protruding section  265  shaped to correspond with depression  240  formed within a peripheral wall  230  of base portion  220 . In addition, a post  267  projects from inwardly protruding section  265 . Post  267  is adapted to engage corresponding aperture  242 . A peripheral flange  270  extends horizontally from a perimeter of cover section  250 , such that when packaging container  210  is in a closed position, peripheral flange  270  abuts flange  245  of base section  220 . Peripheral flange  270  includes a cut out area  271  adjacent to inwardly protruding section  265 , as shown in  FIG. 4D . 
     Laterally extending flange  245  is deformable such that when flange  245  is depressed in a region  275  adjacent to depression  240 , outer and inner segments of peripheral wall  230  move inwardly, thereby releasing post  267  from aperture  242  (and any additional apertures) and opening packaging container  210 . Peripheral flange  270  of cover section  250  includes a cut out area  271  at inwardly protruding section  265  of side wall portion  254 , such as to provide unobstructed access for depressing deformable flange  245  of base section  220  for opening packaging container  210 . As shown in  FIG. 4D , packaging container  210  includes corresponding elements on each side thereof such that when both first and second regions  275  are depressed, cover section  250  is released from base section  220 . 
       FIGS. 5A-5B  illustrate side and enlarged side views of a lockable packaging container  310  according to an additional embodiment. Packaging container  310  includes a mechanism for locking which does not allow for easy opening. In particular, packaging container  310  includes elements corresponding to those of packaging container  10 . Further, packaging container  310  includes at least one obstructive member for preventing the opening of packaging container  310 . In particular, packaging container  310  includes an obstructive member in the form of a recessed face  376  formed in a cover section  350  which extends towards an aperture  343  formed in inner wall segment  330   a  of base section  320  when packaging container  310  is in a closed position. Laterally extending flange  345  is deformable such that when flange  345  is depressed in a region  375  of outer wall segment  330   b  adjacent to depression  340 , outer wall segment  330   b  moves inwardly toward inner wall segment  330   a . However, since recessed face  376  is formed within the top surface and extends adjacent to aperture  342  of inner wall segment  330   a , movement of inner wall segment  330   a  is hindered by recessed face  376 . Therefore, post  367  is not released from apertures  342  and  343  and cover section  350  remains secured in a closed position over base section  320 . 
     As shown in  FIGS. 5C-5F , lockable packaging container  310  may additionally include obstructive members in the form of protuberances  312  extending from the top surface or recessed face  376  adjacent to post  367  of cover section  350 . In particular,  FIGS. 5C-5D  illustrate perspective and side views of locked packaging container  310  according to an embodiment of the invention.  FIGS. 5E-5F  illustrate enlarged views of a locking mechanism of packaging container  310 . As discussed above, laterally extending flange  345  is deformable such that when flange  345  is depressed in a region  375  of outer wall segment  330   b  outer wall segment  330   b  moves inwardly toward inner wall segment  330   a . However, since recessed face  376  and protuberances  312  extends adjacent to aperture  343  of inner wall segment  330   a , movement of inner wall segment  330   a  is hindered by protuberances  312 . Therefore, post  367  is not released from apertures  342  and  343  and cover section  350  remains secured in a closed position over base section  320 . In the embodiment shown in  FIG. 5F , post  367  is longer such that movement of inner wall segment  330   a  is further restricted and packaging container  310  is prevented from opening.

     An additional embodiment is shown in  FIGS. 11E-11H .  FIG. 11A  illustrates a perspective view of a packaging container  900 , in which packaging container  900  is in a closed position.  FIG. 11B  is a perspective view of packaging container  900  in an open configuration.  FIG. 11C  is a side view  11 D is a back view of packaging container  900  in a closed state. 
     Packaging container  900  includes a base section  920  having a chamber  925  defined by an inner wall segment  930   a  and an outer wall segment  930   b  adjoined by a base rim  930   c . Packaging container  900  also includes a cover section  950  pivotally coupled to base section  920  at a hinge  952 . Further, packaging container  900  includes a front end  902  and a back end  904 . 
     In order to facilitate a secure closure of packaging container  900 , outer wall segment  930   b  includes at least one depression  940  formed therein. At least one aperture  942  is formed within depression  940  for engaging an inwardly protruding section formed on a cover section  950 , as will be discussed in detail below. A plurality of apertures  942  and corresponding depressions  940  may be included in some embodiments. Base rim  930   c  also includes a base extension ledge  932  extending therefrom on one side of base section  920 . Thus, the distance between outer wall  930   b  and inner wall  930   a  is greater on a front side of container  900  than the distance between outer wall  930   b  and inner wall  930   a  at the back side of the container  900 . Base rim  930   c  also includes a base sealing channel  944  formed therein for mating with a corresponding feature of cover section  950 . In the embodiment shown, base rim  930   c  with base sealing channel  944  formed therein extends around the entire perimeter of chamber  925 . Further, a laterally extending flange  945  extends outwardly from outer wall segment  930   b  as show in  FIGS. 11A and 11B . Outer wall  930   b  may also include at least one protuberance  947  formed therein to assist in de-nesting the containers when stacked in an open state. 
     In the embodiment shown, cover section  950  of packaging container  900  is pivotally coupled to base section  920  at a hinge  952 . Cover section  950  is configured to pivot about hinge  952  between an open state and a closed state. In particular, cover section  950  includes a top surface having a recessed face  977  surrounded by ledge  978  and a perimeter wall  979 . Cover section  950  also includes cover rim  980  with a cover extension ledge  982  extending therefrom for contacting base extension ledge  932  of base section  920 . Cover rim  980  also includes a cover sealing channel  984  formed therein for mating with corresponding base sealing channel  944  of base section  920 . Together, a base sealing channel  944  and cover sealing channel  984  join to form a container perimeter seal for further sealing the packaging container. The container perimeter seal may extend around the entire perimeter of the packaging container. 
     The mating of base rim  930   c  with base sealing channel  944  and cover rim  980  with cover sealing channel  984  provides a secure friction mating of base  920  and cover  950 . In the embodiment shown, cover rim  980  with cover sealing channel  984  formed therein extends around the entire perimeter of cover section  950 . Perimeter wall  979  includes at least one inwardly protruding section  987  shaped to correspond with depression  940  formed within outer wall segment  930   b  of peripheral wall  30 . In addition, a post  989  projects from inwardly protruding section  987 . In one embodiment, post  989  includes a straight edge portion  989   a  and an angled edge portion  989   b . Alternatively, the entire edge may be angled. Post  989  is adapted to engage corresponding apertures  942  of base section  920 . Further, a peripheral flange  985  extends laterally and outwardly from outer wall segment  979  as show in  FIGS. 11A and 11B . Peripheral flange  985  extends from a perimeter of cover section  950  such that, when packaging container  900  is in a closed position, peripheral flange  985  abuts laterally extending flange  945  of base section  920 . Peripheral flange  985  includes a cut out area  991  adjacent to inwardly protruding section  987 , as will be discussed below. 
     Packaging container  900  includes a closure and release mechanism which allows container  900  to be securely closed, but also easy to open by a user with one-hand. In particular, laterally extending flange  945  is deformable such that when laterally extending flange  945  depressed in a region  975  adjacent to depression  940  of outer wall segment  930   b , outer wall segment  930   b  moves inwardly, thereby releasing post  989  from aperture  942  and opening packaging container  900 . Peripheral flange  985  includes a cut out area  991  at inwardly protruding section  987  of perimeter wall  979 , such as to provide unobstructed access for depressing laterally extending flange  945  at region  975  of base section  920  for opening packaging container  900 . 
     Hereinafter, a process of manufacturing the packaging container according to an embodiment of the present invention is described. The process will be described with specific reference to the embodiment of  FIGS. 11A-11H . Packaging container  900  may be formed completely or partially of a transparent food-safe material, such as crystal clear polypropylene, to allow a user to see the interior of the packaging container. In particular, packaging container  900  is manufactured using a thermoforming process. In order to produce a projection, such as post  989 , or other shaped projection in a vertical or nearly vertical sidewall of a thermoformed package, retractable tooling features are incorporated into a tool, which forms the package. These features can be of a variety of shapes and sizes. 
     Packaging container  900  is formed from a preheated sheet of thermoplastic material that is drawn into, or over a mold to create the desired shape of the end product. After the material has reached a stable set point, where upon it is rigid enough to be removed from the mold without losing the shape of the mold upon which it was formed, the sheet is withdrawn in the opposite direction from which it entered the mold. Typically the sheet enters the mold and is removed from the mold in a vertical fashion. Posts  989  are formed utilizing retractable features, such as a round post, or pin. When the heated plastic sheet is drawn into the mold, the post is in an extended position. Alternatively, the pin may be extended just after the material enters the mold but before it has cooled too much so that it is still be formable around the pin. The plastic forms around the post, thereby adopting its shape. The post is then retracted until the face of the post is flush with the sidewall of the mold. Thus, the post is out of the way such that the plastic product can be removed from the mold. Mechanical linkages and drive mechanisms may be used. Alternately, magnetics, pneumatic cylinders or the like may be employed. 
     Aperture  942  is formed within outer wall segment  930   b  of base section  920 . A punch and die mechanism is utilized to form aperture  942 . In some embodiments, the punch and die may mimic the profile of the formed post  989 , but with a slightly larger profile to allow for clearance and ease of insertion of the formed post  989  within aperture  942 . Alternatively, the cutout may take a shape that is different from the formed projection. For example, the formed projection may be a simple post, while the cutout may be oval in shape. Similarly, aperture  942  may be round and projections may be star, octagonal, or the like, in shape. Aperture  942  is typically formed after the forming of packaging container  10 . In high volume production, the cutting of the aperture may occur at a station between a forming station and a die cutting station. It is in the die cutting station that the planer surfaces of the plastic container are trimmed from the surrounding web of material so that the container can be removed from a leftover perimeter sheet. 
     Aperture  942  may also be formed following a die cutting step, i.e. after the formed and die cut plastic part has been removed from the surrounding left over plastic sheet. Thus, in one embodiment, the formed and die cut package is placed into a mechanical device, which then punches out the apertures. The apertures may also be formed by a manually actuated device punching one hole at a time or by a fully automated system punching all the holes in a package at once, with automated load and unload of the package into the punching mechanism. The apertures may also be cut in the same station as where the planer die cut of the perimeter plastic occurs. 
     In use, an item or items is placed in chamber  925  of base section  920 . Cover section  950  is then rotated to cover base section  920 . At this time, post  989  and inwardly protruding section  987  engages depression  940  and corresponding aperture  942 . In particular, post  989  of cover section  950  penetrates aperture  942  of base section  920 , thereby securing cover section  950  to base section  920  and preventing cover section  950  from being pivoted open. Post  989  includes a straight edge portion  989   a  and an angled edge portion  989   b . In order to open packaging container  900 , applying downward pressure to laterally extending flange  945  at region  975 , which is adjacent to depression  940 , causes deflection of laterally extending flange  945  and outer wall segment  930   b  such that post  989  disengages from corresponding aperture  942  and container  900  is opened. 
     In general, the posts and apertures engage to form a locking feature that uses the shear strength of the post engaged against the wall of material through which the aperture is formed. The force required to separate the posts from the aperture is a function of the shear strength of the formed post, and/or the tear strength of the punched hole. 
     The downward force of closing cover section  950  over base section  920  drives post  989  having beveled or angled edge portion  989   b  down across the outer wall segment  930   b  descending the wall of packaging container  900  until the post “snaps” into the hole. Since the posts and apertures are formed on vertical walls at 90 degrees, a secure closure of packaging container  900  is formed. 
     Although the present invention has been described with reference to the embodiments and the accompanying drawings, it is not limited to the embodiments and the drawings. It should be understood that various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present invention defined by the accompanying claims.
