CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application No. 61/260,821 filed on Nov. 12, 2009, the entire contents of which are herein incorporated by reference. 
     
    
     BACKGROUND 
       [0002]    Liquids such as shower creams, hand soap, facial cream, cosmetics or any detergents that are stored in a plastic bottle and dispensed by a pump are widely used at private and public places. Such pumps enable users to obtain a precise volume of contents, provide users with clean and comfortable usages and avoid potential cross-contamination by users. 
         [0003]    In a conventional pump bottle, a gap is provided between the straw end and the bottom of the bottle or a notch is provided at the straw end, as shown in  FIGS. 1 and 2 . However, a pump can normally not completely dispense all the contents in a bottle. This causes wastages, as contents are not able to be pumped out completely. 
         [0004]    The left over contents usually need to be poured out manually by removing the pump and turn the bottle upside down. This creates inconvenience to users. Additionally, a required amount of the contents can no longer be controlled. The wastage results in additional cost. Moreover, mixing with water to dilute the viscosity for easy pouring becomes a common phenomenon in bath rooms, as most of liquids are of higher viscosity. The pouring out of such diluted fluids is cumbersome. 
       SUMMARY 
       [0005]    Embodiments relate to a container. The container has a top having an opening for filling the container with a content. The container has a bottom having a general gradient, and a side surface intermediate the top and the bottom. The container has a collection reservoir disposed at a lowest part of the bottom, in which the general gradient of the bottom directs the content of the container to the collection reservoir. 
         [0006]    Such containers can be used to store liquid shower creams, hand soap, facial cream, cosmetics or any other detergents. Storing other types of fluids or creams may also be useful. Such containers can be used at private and public places.

     DETAILED DESCRIPTION 
       [0013]    In  FIG. 3 , an embodiment of a pump bottle  300  is shown. The pump bottle may be any type of bottle or container. For example, the bottle may be a vessel, receptacle, vial or other suitable containers. The bottle can be formed from various types of materials. For example, the bottle may be formed from plastic, glass or metal. The bottle may be transparent, translucent or opaque. Other types of materials may also be useful. The bottle includes a top (not shown), sides  301  and a bottom  310 . 
         [0014]    In one embodiment, a top of the bottle accommodates a pump. The pump for example, includes a dispensing nozzle (not shown) and a straw  331 . The pump, for example, may be a manual pump. When the pump is actuated, such as by pushing downwards, contents of the bottle are siphoned through the straw and out through the dispensing nozzle. The contents of the bottle may be any type of liquid. Dispensing other types of materials by the pump may also be useful. The dispensing nozzle may be a spray nozzle or a non-spray nozzle. Other types of pumps may also be useful. 
         [0015]    The sides may be parallel or substantially parallel. In other embodiments, the sides may be tapering toward each other at the bottom. Other bottom shapes, may also be useful. In one embodiment, the sides and the bottom are distinct. For example, the sides and bottom may have an abrupt change in direction. As shown, the sides and the bottom may have an angle θ. In one embodiment, the angle θ is greater than 90°. The angle θ should be sufficient to cause contents of the bottom to flow to a collection area  320  at the bottom surface. For example, the angle θ may be between about 95-135°. Other angles between the bottom and sides which cause contents to be directed to the collection area may also be useful. 
         [0016]    In other embodiments, the sides and the bottom of the bottle may have a smooth transition. For example, the lower sides of the bottle and the bottom do not form an abrupt angle. For example, the sides and the bottom may have a smooth transition. In yet other embodiments, the sides may taper to form a V shape bottle, with the collection area located at the bottom of the V. Other configurations of the sides and the bottom may also be useful. 
         [0017]    In one embodiment, the collection area comprises a distinct area in the bottom. For example, the collection area comprises a recessed portion of the bottom surface. The collection area or recess may have various shapes. For example, the recess may have a cylindrical, domical, ovate, conical, cubical, or oblong shape. Other shapes for the recess may also be useful. Providing a collection area which is not distinct form the bottom surface may also be useful. 
         [0018]    The collection area, in one embodiment, is a lowest portion of the bottom surface. For example, the bottom surface slopes downward toward the collection area. The sloping bottom surface may comprise a constant slope. In other embodiments, the bottom surface may comprise a variable slope. Other configurations of bottom surface and collection area may also be useful. For example, the bottom surface may comprise a combination of constant and variable sloping portions, as shown in, for example,  FIGS. 4-6 . For example, the bottom may have any type of shape, such as a conical, a domical or a plurality of converging planes or other shapes, which directs the contents of the bottom to the collection area. The general slope or gradient of the bottom to the collection area may be configured appropriately depending on the contents of the bottle. For example, a steeper general gradient may be used for the bottom for more viscous fluids. 
         [0019]    The collection area may be located at a central portion of the bottom surface. In other embodiments, the collection area may be disposed in other parts of the bottom surface. The collection area serves as a reservoir for contents of the bottle. For example, the reservoir enables the last remaining contents of the bottle to collect at the collection area. 
         [0020]    The collection area should be sufficient to accommodate the end of the straw of the pump. For example, the collection area should be larger in diameter than the straw of the pump. In one embodiment, the collection area should be slightly larger than the diameter of the straw. In one embodiment, the end includes at least one notch  335 . The notch, for example, may be a v-shaped notch. Other types of shaped notches may also be useful. The notch allows liquid in the collection area to be drawn through the straw for dispensing by the pump. 
         [0021]    In one embodiment, the bottom of the bottle may be fitted with a bottom cap  340 . The bottom cap, for example, provides a flat surface at the bottom of the bottom for it to stand. The cap, for example, may be an integral part of the bottle. In other embodiment, the cap may be a separate component to the bottle. 
         [0022]    The collection area serves as a reservoir for the last remaining contents of the bottle. This enables almost all the contents to be plumped out easily. The leftover contents in the recess will be a small negligible amount. 
         [0023]    The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing embodiments, therefore, are to be considered in all respects illustrative rather than limiting the invention described herein. Scope of the invention is thus indicated by the appended claims, rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
