Description

  The present invention relates to a tray unit applicable to a dispenser container including a pump unit, and a pump system for a dispenser container including the tray unit and a pump unit.

  As a container for storing liquid contents, a dispenser container having a pump unit has become widespread. In the dispenser container, generally, the cap of the pump unit is attached to the opening of the container body by screw means. The pump unit includes, for example, a pump mechanism for pumping up the contents of the container and a discharge head connected to the pump mechanism, and the contents are discharged from a lateral discharge port provided in the discharge head by pushing down the discharge head. (For example, refer to patent document 1) so that a shampoo, a hand soap, etc. can be discharged. Further, as a dispenser container that is suitably used when the content is a cosmetic liquid or the like, a configuration in which a receiving tray for receiving the content is connected to the upper part of the pump mechanism is known (see, for example, Patent Document 2). In a dispenser container with a saucer, for example, a discharge port for discharging contents is formed in the center of the saucer. And if liquid deposits, such as cotton, are pressed against a saucer and the saucer is pushed down, the contents discharged from a discharge mouth can be penetrated into the liquid deposit.

  However, the conventional dispenser container with a saucer has a dedicated structure in which the saucer is integrally incorporated as a whole container. For this reason, the dispenser container with a saucer has poor versatility and is expensive to manufacture.

The inner diameter dimension of the cap fitting cylinder portion 211 is, for example, approximately the same as the outer diameter dimension of the cap 11 or slightly smaller than the outer diameter dimension of the cap 11. The inward wall 212 extends radially inward from the upper end of the cap fitting cylinder portion 211, and is a portion that can contact the upper end portion of the cap (see FIG. 2). As shown in FIG. 3, in this embodiment, four pieces of inward walls 212 separated from each other are equally arranged in the circumferential direction of the cap fitting cylinder portion 211.

  At the lower end of the cap fitting cylinder portion 211, a locking convex portion 211a that protrudes inward in the radial direction is provided. As shown in FIG. 2, the locking convex portion 211 a is a portion that can lock the lower end portion of the cap 11 in a state where the cap fitting cylinder portion 211 is externally fitted to the cap 11. In the present embodiment, the locking convex portion 211 a is provided uniformly over the entire circumferential direction of the cap fitting cylinder portion 211. According to such a configuration, in a state where the cap fitting cylinder portion 211 (first member 21) is externally fitted to the cap 11, the first member 21 is prevented from falling off from the cap 11. As shown in FIG. 4, a plurality of protrusions 211b extending in the axial direction of the cap fitting cylinder portion 211 may be provided as necessary. According to the configuration including the protrusion 211 b, when the cap fitting cylinder portion 211 is attached to the cap 11, the protrusion 211 b comes into pressure contact with the knurl on the outer peripheral surface of the cap 11, and the cap fitting cylinder portion 211 ( The rotation of the first member 21) can be prevented.

  As shown in FIGS. 3 and 4, the standing wall 213 is formed on the upper part of each inward wall 212 and extends upward. As clearly shown in FIG. 3, in the present embodiment, a plurality of (four pieces) standing walls 213 are evenly arranged in the circumferential direction of the cap fitting cylinder portion 211. As shown in FIG. 2, when the cap fitting cylinder portion 211 (first member 21) is attached to the cap 11, the upright wall 213 extends toward the tray portion 222 of the second member 22 described later. Yes.

  The upright wall 213 has a locking step 213a, a protruding portion 213b, and an inclined portion 213c. The locking step 213a is at a position away from the inward wall 212 by a predetermined distance. The protruding portion 213b is adjacent to the locking step portion 213a in the circumferential direction of the cap fitting cylinder portion 211, and protrudes above the locking step portion 213a (on the tray portion 222 side shown in FIG. 2). Yes. The inclined portion 213c is connected to the opposite side of the protruding portion 213b with respect to the locking step portion 213a, and is inclined so as to approach the inward wall 212 (displace downward) as the distance from the locking step portion 213a increases. Although the details will be described later, the standing wall 213 constitutes a “stopper mechanism” in the present invention.

  The annular wall 214 extends from the outer periphery of the cap fitting cylinder portion 211 with a constant dimension outward in the radial direction.

  The surrounding cylinder part 215 is connected to the outer peripheral part of the annular wall 214 and is positioned radially outward from the cap fitting cylinder part 211. The surrounding cylinder part 215 extends in the axial direction of the cap fitting cylinder part 211 and overlaps the entire cap fitting cylinder part 211 and the entire standing wall 213 when viewed in the radial direction. In addition, the part near the upper end of the surrounding cylinder part 215 is gradually diameter-expanded as it goes upwards.

  5-7, the 2nd member 22 has the nozzle fitting cylinder part 221, the saucer part 222, the large diameter cylinder part 223, and the latching | locking part 224, for example, predetermined intensity | strength, such as a polypropylene Are integrally formed of a synthetic resin material.

  The nozzle fitting cylinder portion 221 is a portion that is externally fitted to the discharge nozzle 14 of the pump unit 1. The inner diameter dimension of the nozzle fitting cylinder portion 221 is slightly smaller than the outer diameter dimension of the discharge nozzle 14, for example. As a result, as shown in FIG. 2, when the nozzle fitting cylinder portion 221 (second member 22) is attached to the discharge nozzle 14, the discharge nozzle 14 is press-fitted into the nozzle fitting cylinder portion 221. The second member 22 is prevented from falling off the discharge nozzle 14.

  The tray part 222 covers the upper end of the nozzle fitting cylinder part 221 and extends radially outward from the nozzle fitting cylinder part 221. The saucer part 222 has a substantially constant thickness and is curved so that the central part is recessed. A discharge port 222 a penetrating in the thickness direction is formed in a portion radially inward of the tray fitting portion 221 in the tray portion 222. In the present embodiment, a plurality (three) of the discharge ports 222a are formed, but the number and positions of the discharge ports can be variously changed.

  The large diameter cylindrical portion 223 is connected to the lower surface of the tray portion 222 and extends downward, and surrounds the nozzle fitting cylindrical portion 221. The locking portion 224 is connected to the lower surface of the tray portion 222 and the outer peripheral surface of the large-diameter cylindrical portion 223, and has a plate shape having a predetermined width in the radial direction and extending downward. As shown in FIG. 7, in the present embodiment, a plurality (four pieces) of the locking portions 224 are equally arranged in the circumferential direction of the nozzle fitting cylinder portion 221. These locking portions 224 are provided at positions corresponding to the upright walls 213 of the first member 21 when viewed in the axial direction of the nozzle fitting tube portion 221 (cap fitting tube portion 211).

  8 and 9 show the positional relationship between the standing wall 213 and the locking portion 224 when the cap fitting cylinder portion 211 is viewed in the axial direction. In these drawings, the locking portion 224 is represented by a virtual line, and the locking portion 224 and the locking step portion 213a of the upright wall 213 are hatched.

  FIG. 8 shows a state where the locking portion 224 and the locking step portion 213a overlap each other when viewed in the axial direction. Here, as understood with reference to FIGS. 8 and 2, when the second member 22 is pressed downward, the locking portion 224 of the second member 22 becomes the locking step of the upright wall 213 (first member 21). The second member 22 is prevented from moving downward by contacting the portion 213a. At this time, pushing of the discharge nozzle 14 toward the pump mechanism 12 is prevented, and the positional relationship of the second member 22 with respect to the first member 21 is at the first relative rotational position referred to in the present invention.

  FIG. 9 shows a state where the locking portion 224 and the locking step portion 213a do not overlap when viewed in the axial direction. Here, as understood with reference to FIGS. 9 and 2, when the second member 22 is pressed downward, the second member 22 can be moved downward. At this time, the discharge nozzle 14 is allowed to be pushed into the pump mechanism 12, and the positional relationship of the second member 22 with respect to the first member 21 is the second relative rotational position referred to in the present invention. The locking portion 224 of the second member 22 constitutes a “stopper mechanism” in the present invention.

  The second member 22 takes the second relative rotation position in addition to the case where the locking portion 224 and the standing wall 213 shown in FIG. 9 do not overlap with each other, as well as when the locking portion 224 and the standing wall are viewed in the axial direction. The inclined portion 213c of 213 may overlap. When the locking portion 224 and the inclined portion 213c overlap when viewed in the axial direction, when the second member 22 is pressed downward, the second member is pushed down while rotating while the locking portion 224 is in contact with the inclined portion 213c.

  For the second member 22 of the tray unit 2, switching between the first relative rotational position shown in FIG. 8 and the second relative rotational position shown in FIG. 9 is performed by rotating the second member 22 around the axial direction. .

  Next, the operation of the tray unit 2 and the pump system A according to the above-described embodiment will be described.

  The tray unit 2 includes a first member 21 that is fitted to the cap 11 of the pump unit 1 and a second member 22 that is fitted to the discharge nozzle 14 of the pump unit 1. By mounting the tray unit 2 on the pump unit 1 and attaching the pump unit 1 with the tray unit 2 (pump system A) to the opening of the container, the tray unit 2 can be used as a dispenser container with a tray. Therefore, according to this embodiment, the function of a saucer can be easily given to the existing dispenser container.

  The first member 21 and the second member 22 have different relative rotational positions of the second member 22 with respect to the first member 21, thereby preventing the discharge nozzle 14 from being pushed toward the pump mechanism 12 (first relative position). A stopper mechanism that can be switched between a rotation position) and an allowable state (second relative rotation position) is provided. According to such a configuration, the first member 21 and the second member 22, which are separate members, cooperate to operate the stopper mechanism, and by a simple operation such as rotating the second member 22 around the axial direction, Unintentional discharge of the contents of the container can be prevented.

  The stopper mechanism includes an upright wall 213 provided on the first member 21 and extending toward the tray portion 222 of the second member 22, and a locking portion 224 provided on the second member 22. The upright wall 213 includes a locking step 213a that can come into contact with the locking portion 224 when the second member 22 is in the first relative rotation position with respect to the first member 21, and the locking step 213a. On the other hand, it has the protrusion part 213b which adjoins the circumferential direction of the cap fitting cylinder part 211, and protrudes in the saucer part 222 side. According to such a configuration, when the second member 22 is switched from the second relative rotation position (a position where pressing is allowed) to the first relative rotation position (a position where pressing is prevented), the second member 22 is changed from the state shown in FIG. The member 22 is rotated counterclockwise. Then, the locking portion 224 comes into contact with the protruding portion 213b and the rotation of the second member 22 is prevented. As shown in FIG. 8, the locking portion 224 and the engaging portion adjacent to the protruding portion 213b are viewed in the axial direction. It will be in the state where the stop part 213a overlaps. According to such a configuration, the first relative rotational position and the second relative rotational position of the second member 22 can be accurately switched.

  The surrounding cylinder part 215 of the first member 21 is located radially outward from the cap fitting cylinder part 211 and the standing wall 213, and the whole cap fitting cylinder part 211 and the whole standing wall 213 as viewed in the radial direction. It overlaps with. According to such a structure, the cap fitting cylinder part 211 and the upright wall 213 which are located inside are obstructed by the surrounding cylinder part 215, and are difficult to visually recognize from the outside.
