Description

[Detailed Description of the Invention] The present invention relates to a pump injection type pot in which a lid is placed on the upper part of the pot body so as to be openable and closable.

In a typical pump pouring pot that uses a pump device to pour out liquid, it is used to cover the area around the horizontal pouring pipe of a series of liquid passages for pouring liquid. A lower beak portion with a U-shaped cross section is formed on the pot body side, and an upper beak portion with an inverted U-shaped cross section is formed on the lid side.

However, in conventional pump injection pots with upper and lower beaks, the upper beak is prone to deformation due to external impacts or changes over time (in particular, the walls on both sides of the upper beak expand laterally). there were.

In addition, the upper beak back plate is fixed to the back side of the upper beak, but the upper beak back plate in conventional pump injection pots is simply to cover the back side of the upper beak. It does not have the effect of preventing deformation of the beak, especially the expansion of both side walls of the upper beak as described above.

In view of the above-mentioned problems with conventional pump injection pots, the present invention has been developed to prevent deformation of the upper beak part and to easily position the upper beak back plate attached to the back side of the upper beak part. The purpose of this invention was to provide a pump-injecting pot with a high-performance pump.
