Definitions
- the present invention relates to a pump device for a container, and more particularly to a pump device for a container that can dispense the entire amount of the contents almost to the end.
- a container shown in FIG. 30 is known as a container that discharges a fixed amount of contents that have a high viscosity or that are deteriorated by contact with outside air.
- the container 1 accommodates therein a flexible bag 2 filled with a flexible content, and has a pump 4 in a mouthpiece 3.
- the pump 4 includes an operating part 5 exposed to the outside of the container 1 and a suction part 6 inserted into the sealed bag 2.
- the suction part 6 has a pipe shape, and the tip of the suction part 6 is opened as a suction port 6 a and extends near the bottom of the sealed bag 2.
- the operating section 5 is moved down, the operating section 5 is raised by springback, and the inside of the suction section 6 becomes a negative pressure, and the contents 7 in the sealed bag 2 become the suction port 6a. From the pump.
- the close contact of the airtight bag 2 with the suction section 6 prevents the contents 7 at the top of the airtight bag 2 from flowing to the suction port 6 a of the suction section 6, and the bottom of the airtight bag 6 is extremely
- the partial withdrawal causes the contents 7 to stay at the top.
- the present invention has been made in view of such problems of the related art, and has a sealed bag. Pump that prevents clogging of the suction port so that the contents can be smoothly and reliably poured out, and that the entire amount of the contents can be poured out, and has excellent productivity. It is intended to provide a device. Disclosure of the invention
- the present invention employs the following means in order to solve the above problems.
- the container pump device of the present invention is used by being attached to a container having a content-filled sealed bag that shrinks due to internal negative pressure caused by taking out the content, and an operating portion exposed to the outside of the container.
- a container pump device having a suction unit inserted into the container and suctioning the contents from a suction port, wherein a base end is attached to the suction port of the suction unit and a distal end is the contents-filled sealed bag.
- a gap holding rod extending toward the inner bottom of the gap holding rod, and convex portions and concave portions extending from the base end side to the distal end side of the gap holding rod are provided alternately in the circumferential direction on the outer peripheral surface of the gap holding rod. It is that you are.

- a container with a closed bag filled with contents that shrinks due to the internal negative pressure caused by taking out the contents (the innermost layer in a so-called laminated container also corresponds to this)
- the inside of the container is depressurized as the contents are poured out.
- the content-filled airtight bag is pulled by the negative pressure and peels off from the outer layer, and only the inner layer becomes a bag and shrinks and deforms.
- the suction port When the gap holding rod is attached to the suction port of the suction section, the suction port is always kept open. Even when the content-filled airtight bag is in close contact with the gap holding rod, the content-filled airtight bag is in close contact with the convex portion of the gap holding rod but not with the concave portion, so that this concave portion is secured as a passage for the content. . Therefore, even when the content is running low, it is possible to reliably suck up the content.
- the gap holding rod may be fitted in the suction port and fixed, or may be attached to the suction port via a connection pipe for attachment.
- the difference in the action characteristics depending on whether the “outermost side of the convex portion” in the sectional shape of the gap holding rod is a circular arc or a straight line will be described.
- the content-filled sealed bag used in the present invention is a flexible bag having both flexibility. Since it is formed of a material, the action of closely adhering to the gap holding rod and ensuring the passage of the contents is not only the material of the sealing bag, the viscosity of the contents, etc., but also the cross-sectional shape of the gap holding rod. Depends on. Hereafter, each will be discussed.
- the passage of the contents should be concentrated in the recess as much as possible.
- a passage is provided in the gap between the “outermost side of the protrusion” and the sealing bag (innermost layer).
- the passages are dispersed, and the perimeter of the passage cross-section becomes longer (the surface area of the inner wall of the passage is larger even at the same flow rate), and the frictional loss becomes more severe compared to the total cross-sectional area of the resulting passage.
- the so-called pump loss increases.
- One of the means to solve the above (B) and (C) is a force that is conceivable to provide a stronger (larger spring constant) spring. Impair.
- the soft airtight bag is repeatedly damaged by the end of the outermost side of the protruding portion and is hardly adopted every time the airtight bag comes into close contact with or detaches from the gap holding rod.
- the outermost side of the ⁇ part of the arc that is outwardly convex this can be prevented.
- the gap holding rod is A molding method other than the profile extrusion molding method using a dedicated die is also possible.
- a free gap holding rod is not restricted to manufacturing equipment. Design is possible.
- the pump device of the present invention is also realized after adding the following constituent elements.
- the first is to use a gap holding rod formed by the profile extrusion molding method. Since the gap holding rod can be formed by profile extrusion and cut to a predetermined length for use, productivity is extremely high and cost reduction can be achieved.
- the irregular extrusion molding method is a method in which a thermoplastic material is heated and pressurized in an extruder to make it into a fluid state, and is continuously extruded from a die to form an irregularly shaped product.
- a swelling end is provided at the tip of each projection of the gap holding rod.
- the gap holding rod is in an unstable state until it is extruded from the die by the profile extrusion molding method and is cooled and hardened, the provision of the bulging end improves the shape retention of the gap holding rod therebetween.
