Description

  The present invention relates to a container with a pump in which the inner pan rises as the filling capacity of the content decreases, and in particular, avoids a malfunction due to the inclination of the pressing head that operates the pump, thereby ensuring reliable contents. This is what is going to be realized.

  Many containers with cosmetics, hair styling, shampoo, rinse, etc. that are equipped with pumps are marketed regardless of the handy type or the stationary type, so that the contents in the container are hygienic and efficient. Can be poured out into

  As a conventional container with a pump, a container in which the suction port of the pump is located directly below the mouth of the container and the bag-like storage chamber is reduced and deformed as the contents are taken out, and a filling space for the contents A container or the like that slides the inner dish toward the suction port of the pump as the filling amount of the contents decreases by disposing the inner dish therein (see, for example, Patent Document 1). If the pressing head is biased, the stem connected to the pressing head is tilted, making it difficult to operate the pump (the shaft center of the pump piston and the shaft center of the stem are displaced). ), There was still room for improvement because the contents could not be stably poured out.

This container main body 1 has an upper end opening 1a, and surrounds the edge of the bottom plate 1b. The container body 1 cooperates with a cylindrical body 1c (which is integrally formed with the bottom plate 1b) to store contents inside. A filling space M is formed.

  In addition, 2 is an outside air introduction hole provided in the bottom plate 1 b of the container body 1, and 3 is a pump that discharges the contents in the container body 1.

  The pump 3 has a cylindrical cylinder 3a having a suction port h for contents at the bottom, a piston 3b slidably disposed in the cylinder 3a, and the other end (upper end) inserted through the through hole of the piston 3b. A hollow stem 3c connected to a cylinder of a pressing head, which will be described later, a retaining ring 3d that is fixedly held by a flange portion at the upper opening end of the cylinder 3a, and prevents the piston 3b from coming out of the cylinder 3a; The valve body (three-point valve or the like) 3e is disposed at the suction port h and is opened only when the contents are sucked.

Reference numeral 4 denotes a pressing head for operating the pump 3. The pressing head 4 is integrally provided on a disk-shaped top cover 4a having a diameter slightly smaller than the upper end opening 1a of the container body 1 located at the top of the pump 3, and a lower surface of the top cover 4a. A cylindrical body 4b connected at the upper end of the hollow stem 3c of the pump 3 and a spring 4c that elastically supports the top cover 4a. A peripheral wall 4a ₁ that hangs down from an outer edge portion of the top cover 4a. Is provided.

The top cover 4a of the press head 4 has a central opening 4a ₂ is provided, the opening 3c ₁ hollow stem 3c, discharging the contents from said central aperture 4a ₂ through the internal passage 3c ₂ Be able to. Here, the piston 3b is disposed in a space formed between the annular body t provided at the distal end portion of the hollow stem 3c and the distal end of the cylindrical body 4b, and the piston 3b is disposed in this space. The tip of the cylinder 4b comes into contact with the rear end (upper end) of the piston 3b when pushed by the pressing head 4 (when the contents are discharged). While the piston 3b is slid toward the suction port h of the cylinder 3a, when the pressing head 4 is restored to the initial state (at the time of suction of the contents), the annular body t provided at the tip of the hollow stem 3c is Abutting on the tip (lower end) of the piston 3b, the piston 3b is slid toward the upper side of the cylinder 3a.

  Reference numeral 5 denotes a middle dish that is arranged in the filling space M of the container body 1 and slides toward the upper end opening 1a as the filling capacity of the contents decreases. The inner plate 5 is provided with a sliding member 5 a that is in contact with the inner peripheral wall of the cylindrical body 1 c of the container body 1 at the outer edge thereof.

 Furthermore, 6 is a base that holds the pump 3 together with the pressing head 4. The base 6 covers the bottom wall 6a having a large surface area that covers the upper end opening 1a of the container body 1, the peripheral wall 6b integrally connected to the edge of the bottom wall 6a, and the central opening H of the bottom wall 6a. It consists of the holder 6c arrange | positioned. The outer peripheral surface of the peripheral wall 6b is provided with a locking ring 6d that forms a groove that is opened downward between the peripheral wall 6b and is fitted to the protruding end of the cylindrical body 1c by an engaging means such as an undercut. By combining, the base 6 is fixed to the upper end opening 1a of the container body 1.

Holder 6c includes a cylindrical body 6c ₁ interpolate the non pullout the pump 3 itself, leaving the suction port h of the pump 3, to surround the tube body 6c ₁ are integrally connected to a lower end of the cylindrical body 6c ₁ in a thin strip 6c ₂ which is arranged, the thin strip (or disc-like thin body) are integrally connected to the outer edge of 6c ₂ bottom wall 6a cylindrical body provided around the central opening H of the and a retaining ring 6c ₃ grooved fitted to 6d.

7, the cover cap covers the press head 4 in conjunction to the upper end of the peripheral wall 6b of the base 6, 8 provided at the upper end of the retaining ring 6c ₃ of the holder 6c, located inside the lower end of the spring 4c A guide (cylinder) 9 for positioning the spring 4c is provided on the lower surface of the top cover 4a, and is a guide (cylinder) for positioning the spring 4c located inside the upper end of the spring 4c.

  In the container with a pump configured as described above, when a pressing force is applied to the top cover 4a of the pressing head 4, the top cover 4a is pushed down against the biasing force of the spring 4c, and the piston 3b Then, it is pressed by the cylinder 4b and slides toward the bottom of the cylinder 3a.

  After the piston 3b slides to the lowest end (bottom dead center) of the cylinder 3a, if the pushing force applied to the pushing head 4 is removed, the pushing head 4 returns to the initial state by the urging force of the spring 4c. At this time, the piston 3b slides together with the hollow stem 3c toward the top of the cylinder 3a.

  When the piston 3b slides toward the upper part of the cylinder 3a, the inside of the cylinder 3a becomes negative pressure. Therefore, the valve body 3e is opened, and the contents in the container are sucked into the cylinder 3a through the suction port h.

After the pressing head 4 returns to the initial state (top dead center), when a pressing force is again applied to the top cover 4a, the inside of the cylinder 3a is pressurized, and the contents present therein are stored in the hollow stem 3c. Through the opening 3c ₁ , its internal passage 3c ₂ , and the internal passage of the cylinder 4b of the pressing head 4, it is discharged from the central opening 4a ₁ of the top cover 4a, and such operations are repeated, that is, the pressing head 4 By repeatedly pushing and returning the top lid 4a, the contents can be continuously discharged. When the contents are sucked by the pump 3, the filling space M in the container body 1 becomes negative pressure, As the contents decrease, the inner tray 5 rises toward the upper end opening 1 a of the container body 1.

  In the container with a pump according to the present invention, for example, even if a pressing force as shown in FIG. 2 is applied to the top wall 4a of the pressing head 4, the pump 3 tilts following the pressing force. Therefore, the pump can be reliably operated regardless of which part of the top cover 4a is pressed (the shaft core of the piston 3b and the shaft core of the hollow stem 3c are always constant). Stable dispensing can be performed.

  The container with a pump according to the present invention is basically composed of a synthetic resin except for the spring 4c. Although the holder 6c is illustrated as being separate from the bottom wall 6a of the base 6, the holder 6c may be formed integrally with the bottom wall 6a of the base 6, and this is not a limitation.

Further, in order to guide the easy tilting of the pump 3, the case holder 6c, in which a thin strip 6c ₁ was easily deflected by thinning the portion connecting the cylindrical body 6c ₁ and a retaining ring 6c ₃ Example As shown in this figure, a soft belt (elastomer, rubber, etc.) having the same thickness as the cylindrical body 6c ₁ and the locking ring 6c ₃ and integrated by insert molding or the like is applied to this part. This also makes it possible to easily tilt the pump 3.

  In the embodiment of the present invention, the middle dish 5 is arranged in the filling space M of the container body 1 and the middle dish 5 is slid upward as the filling capacity of the contents decreases. However, the cylinder 3a of the pump 3 is provided with a cylinder surrounding the suction port h, and a suction pipe extending toward the bottom of the container is connected to the cylinder and the contents are sucked by the suction pipe. It is also possible to apply, and in this case, it is not necessary to install the intermediate tray 5.

  It is possible to provide a container with a pump capable of operating the pump and discharging the contents reliably regardless of which part of the pressing head is applied.
