     FIELD OF THE INVENTION  
      The present invention relates generally to a structure for a liquid container pump, and more particularly to a pump with anti-lock device, and an extension part and sealable lid that can seal the outlet of the outlet tube, and keep the foreign object from coming in.  
     BACKGROUND OF THE INVENTION  
      There are many products with liquid container (such as lotion bottle) on the market today, and its pump stays sealed and down before it is sold, and the consumer can just turn the pump to an angle for the pump to pop up when the consumer desires to use. The consumers sometime turn the pump mentioned above purposely or not purposely when they are looking at the products in the supermarket, and cause the pump to pop up and ready to use. Maybe the consumers push the pump down so that it shows that is unopened. Except, if the pump on the same liquid container has been opened by the consumers mistakenly repeatedly, the lotion inside may be squeezed out, and the quality of the product may be affected. Therefore, the inventor has developed a structure that can prevent the pump of the liquid container being opened mistakenly before it is sold. It primarily includes an upper stopper and a lower stopper, and the upper stopper is used to restrict the pump of the liquid container, and the lower stopper is used to position the opening of the bottle of the liquid container, and a pre-snap rib is placed between the upper and the lower stoppers.  
      By this design, the pump would not turn if the consumer desires to turn the pump with regular forces because the pump is restricted by the pre-snap rib, however, when the consumer purchases the product, the pre-snap rib may be broken by stronger force, and the pump can be turned successfully. In addition to the pump being opened mistakenly mentioned above, the application of the conventional structure of this liquid container still has the following problems on the outlet tube of its pump: the outlet tube of the pump has an open tube opening under the regular circumstances, and this outlet tube is usually designed like a horizontal protruding state, therefore, the chances of some ill-intentioned customers sticking foreign objects inside increases, and causes the foreign objects to accumulate dust inside the outlet tube, and seriously affects the product&#39;s original quality and reputation.  
      Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.  
      To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.  
     BRIEF SUMMARY OF THE INVENTION  
      The present invention mainly uses the upper stopper of the anti-lock device for the liquid container and extension part that extends to the outlet of the outlet tube, and places a sealable lid at the end of the extension part, which seals the outlet of the outlet tube. It can prevent foreign objects from coming into the container from the outlet  114  of the outlet tube  11  on top of keeping it from being opened with the anti-lock device. It further protects the quality of the liquid container and its reputation.  
      Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

     DETAILED DESCRIPTION OF THE INVENTION  
      The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.  
      As shown in  FIGS. 1-3 , there is a preferred embodiment of the anti-foreign object structure for a liquid container pumps.  
      An anti-lock device A is placed between the pump  10  and the tip  21  of the container bottle, and the anti-lick device A, including an upper stopper  30  and a lower stopper  40 . Among them, the upper stopper  30  has a limit stopper  31  that is placed at the end  112  of the outlet tube  11  of the pump  10 , and the lower stopper  40  has a connecting part  41  that can be placed on the tip  21  of the container bottle  20 , and a pre-snap rib  50  is placed between the upper and lower stopper  30   40 .  
      An extension part  60  has a pre-designated area (it is the front end of the limit stopper  31  in the present invention) that is connected to the upper stopper  30  mentioned above, and the end of the extension part  60  extends toward the outlet  114  of the outlet tube  11 .  
      A sealable lid  70  is placed at the end of the extension part  60  mentioned above, and the shape of the sealable lid  70  can seal the outlet  115  of the outlet tube  11  and to keep the foreign objects from coming in. The example of the sealable lid  70  is presented as shown in  FIG. 3 , and can be a cover, which can cover the outside of the outlet  114  of the outlet tube  11 . Also, the sealable lid  70 B as shown in  FIGS. 7 and 8  can be a depository style that can be deposited inside the outlet  114  of the outlet tube  11 . Under the regular circumstances, the sealable lid  70  can connect to the upper stopper through extension part  60  and create positioning effect, therefore, it can not be opened, unless the pump  10  is turned forcefully and break the pre-snap rib  50 . When the upper stopper  30  and the lower stopper  40  is broken off, the sealable lid  70  can be released, and the user may open it successfully, and open the outlet  114  of the outlet tube  11  for use.  
      Among them, the limit stopper  31  of the upper stopper  30  is shown as  FIG. 3 , which is a C-shaped gutter that restricts the outlet tube  111  by clapping. Also, the limit stopper  31 B is shown in  FIG. 5 , which is a through hole type that restrict the outlet tube  11  by going through it.  
      Moreover, the connecting part  41  of the lower stopper  40  is shown in  FIG. 3 , which is a plate with wide that is only on the partial area of the tip  21  of the container bottle  20 . Also, the connecting part  41 B shown in  FIG. 4  is a ring shape device that surround the tip  21  of the container bottle  20 .
