1. Field of the invention
The present invention relates to a new pump container, more particularly to a pump container with a pick-up port for sucking up the residual content on the bottom portion of the pump container.
2. Brief Description of the Prior Art
The structure of a container with a pump device is widespread in daily life items for its handiness, especially widely used in receiving emulsions for bathing or cleaning purpose. As shown in
In spite of the handiness of the pump container, the content of the pump container cannot be sucked up completely when it is about to be consumed up (usually the liquid level is approximately 0.5 cm from the bottom). The person skilled in the art can understand that the air within the container (10′) is sucked into the inlet port (22a′) of the hollow tube (22′) to destroy the vacuum state within the hollow tube (22′). It is this reason that the residual content on the bottom of the pump container cannot be sucked up completely when it is about to be consumed up. This is not only a waste, but also causes environmental pollution when the pump container with residual content is discarded. In most cases, user will detach the pump device (20′) from the container and then put some water into the container (10′) from the mouth portion (12′) for dilution, so as to use up the residual content. However, it is considered inconvenient in so doing, thus there is an expectation on the improvement of the conventional pump container.
The main object of this invention is to provide a pump container with a pick-up port in such a manner that the defect of incapability of sucking up the residual content on the bottom of the pump container can be improved by the pick-up port provided at the lowest point of the bottom of the pump container.
In order to achieve the above and another objects, the pump container with a pick-up port comprises a receiving portion at one end and a mouth portion at the other end of the container, a pump device having a pump fixed and enclosed within the mouth portion by a cap, the pump having a hollow tube with one end extending to the receiving portion, the other end being provided outside the mouth portion, a push button being provided at the top end of the pump device and connected with a discharge port, characterized in that a pick-up port is formed at the lowest point on the bottom of the receiving portion and the pick-up port is closed by a closing means.
According to the present invention, an inclined surface is formed on the bottom of the receiving portion, the pick-up port is located at the corner of the lowest point of the inclined surface such that the residual content on the bottom flows to the pick-up port and is collected easily.
In so doing, if the residual content on the bottom of the pump container cannot be sucked up completely when it is about to be consumed up, the closing means is detached from the pick-up port so that the residual content on the bottom can be taken out thoroughly through the pick-up port. Therefore environment pollution by the residual content is avoided.

The technical features of the present invention will become more apparent by the detailed description of following embodiments, which are merely illustrative rather than restrictive on the scope of the present invention, in conjunction with the attached drawings. Firstly referring to
An inclined bottom surface 14 is provided at the bottom end of the receiving portion 11 of the container 10. A pick-up port 30 is provided at the lowest corner of the inclined bottom surface 14. A closing means 31 such as a film is detachably adhered on the outside of the pick-up port 30 and the pick-up port 30 is closed by a closing means 31. As shown in
The blow molding technology to form the inclined bottom surface 14 is of high-level technology. As one of the solutions, a pad 15 having larger thickness at the opposite side of the pick-up port 30 and then gradually becoming thinner toward the direction of the pick-up port 30 can also be used as a supplement attached to the underlying of the bottom of the container 10.
Next referring to
In this embodiment, a hopper shape bottom 14′ with inclined surfaces from both sides to the center is formed at the bottom end of the receiving portion 11 of the container 10. A pick-up port 30 is formed at the lowest point of the bottom 14′, which has a downward-protruding tube portion 30a having outside thread on it. Corresponding to the shape of the bottom 14′ of the container 10, the closing means 31 is formed as a hopper with inclined surfaces from both sides to the center, which underlies the bottom 14′ of the container 10 as a complementary portion. A cap 31a is projected upwardly at the inner center of the closing means 31, which has a thread portion formed at inner diameter to engage with the tube portion 30a.
In this way, if the residual content on the bottom of the pump container 1 cannot be sucked up completely when the content is about to be consumed up, the closing means is released from the bottom of the container 10 such that the cap 31 a closing the pick-up port 30 is detached from tube portion 30a. Thus, the residual content on the bottom can be taken out thoroughly through the pick-up port 30. Therefore environment pollution by the residual content is avoided.
In addition, a variation of the inclined bottom surface 14 is shown in

The equivalent modifications and variations made without departing from the spirit and principle of the present invention are still considered to be within the scope of the present invention.
