Description

  The present invention relates to a pump refill container.

  In consideration of recent waste disposal circumstances, it has been proposed that after using a liquid, only the container for storing the liquid is replaced with a new refill container and the pump itself is used again. (For example, see Patent Document 1 or Patent Document 2)

  The replacement container for a pump described in Patent Document 1 is a standing pouch-type replacement container, and has a configuration in which the replacement container is detachably attached to a pump that is supported so as to stand upright by a cylindrical support. Yes.

  Moreover, the ejection container described in Patent Document 2 includes an outer case, an exchange container, and an ejection tool. The outer case has shape retention, and has an opening at the top, and can be opened and closed separately. Provided. In addition, the exchange container has a shape-retaining mouth portion and a non-shape-retaining container portion, the contents are stored in the container portion, the exterior case is opened, and the mouth portion is fitted into the opening portion. The container is housed inside, the outer case is closed, and the inside is replaceably attached. Further, the ejection tool is attached to the upper part of the outer case in the form of a pump.

  The former has the feature that it can be manufactured at low cost, but it is relatively complicated and cumbersome to replace because it has a structure in which the tip of the replacement container is cut and the cut portion is sandwiched between pumps. In addition, if the replacement container with the tip cut off is mistakenly tilted, a large amount of liquid may be leaked.

  In the latter case, replacement is relatively complicated and troublesome, and if the container is accidentally tilted at the time of replacement, a large amount of liquid may be leaked. Moreover, if the pump is removed, the liquid in the container can be easily refilled.

JP 2001-019013 A Japanese Patent Laid-Open No. 08-011960

  The present invention has been made in view of the above points, and can be replaced with an extremely simple operation. Moreover, even if the pump is accidentally tilted during replacement, the leakage of stored liquid is minimized. The present invention proposes an excellent refill container for a pump that can be limited and can prevent mischief such as refilling of stored liquid as much as possible.

  The first means is configured as follows. That is, a pump refill container to be used with the pump B, comprising a container body A1 with the mouth-and-neck part 12 upright, and a closure A2 fitted and fixed to the mouth-and-neck part 12; A2 is a seal cylinder portion 23 that is liquid-tightly fitted to the inner surface of the mouth-and-neck portion 12, and a plurality of elastic members that project from the seal cylinder portion 23 in a circumferential radial direction through a slight gap d that is slit-shaped. A plate 26, and a blocking cylinder 28 provided so as to be able to be cut off by connecting the peripheral part with a breakage part 29, while interrupting the inside and outside of the mouth and neck part 12 to the support cylinder 24 standing up above the seal cylinder part 23, A pull ring 30 is provided that is detachably fitted to the outer periphery of the support cylinder 24 and is connected to the closing plate 28 by a flexible connection band 32.

  The second means is configured as follows. That is, in the first means, the elastic plates 26 are gradually lowered inward.

  The third means was configured as follows. That is, in any one of the first means and the second means, the pull ring 30 is configured such that the upper surface thereof is at least above the upper surface of the closing plate 28 and surrounds the closing plate 28. .

  The fourth means is configured as follows. That is, in any one of the first to third means, the lower end portion of the outer peripheral surface of the closing plate 28 is connected to the upper end portion of the inner peripheral surface of the support cylinder 24 by the thin broken portion 29.

  The fifth means is configured as follows. That is, in any one of the first to fourth means, the lid A2 is made of synthetic resin in a state where the pull ring 30 is supported above the support cylinder 24 by the connecting band 32. Molded integrally.

  According to the present invention, it is a simple structure in which a closure A2 is simply fitted to a normal container body A1, and since the use of the normal container body A1 is possible, it is rich in versatility and can be manufactured at low cost. There is. Further, in use, for example, after pulling up the pull ring 30 and cutting and removing the closing plate 28, it is possible to replace it with a simple operation of mounting the pump B removed from the used container. Simple. Furthermore, since the elastic plates 26... Are provided adjacent to each other through a small slit d in the circumferential direction so as to protrude radially, even if the container is accidentally tilted after opening, the liquid leaks out. The amount can be made as small as possible, and there is an advantage that leakage can be almost prevented especially when the stored liquid has a high viscosity. In addition, it is difficult to quickly inject the liquid due to the presence of the elastic plates 26, and therefore, mischief such as refilling of the liquid can be prevented as much as possible.

  When each elastic plate 26 is configured to gradually descend inward, when the pump B is mounted, the elastic plate 26 is easily elastically deformed so that the whole is rotated downward by the pipe B3 and the cylinder B2. Also, there is an advantage that when the pump B is extracted, the adhering liquid around the cylinder B2 and the pipe B3 can be more efficiently removed. In addition, there is an advantage that the mold can be removed more naturally at the time of manufacture due to the presence of the closing plate 28 above the same.

  When the pull ring 30 is configured so that the upper surface thereof is at least above the upper surface of the closing plate 28 and surrounds the closing plate 28, the pull ring 30 protects the closing plate 28 from external force, and the external force It is possible to prevent inconveniences such as disconnection of the connecting broken portions 29 as much as possible.

  When the lower end portion of the outer peripheral surface of the closing plate 28 is connected to the upper end portion of the inner peripheral surface of the support cylinder 24 by a thin broken portion 29, there is an advantage that the removal and removal of the closing plate 28 can be performed more easily.

  When the closure A2 is integrally formed of synthetic resin in a state where the pull ring 30 is supported above the support cylinder 24 by the connection band 32, the connection between the pull ring 30 and the closing plate 28 is a separate process. Since it is not necessary and manufacturing is not complicated, it can be stored and transported with the pull ring 30 fitted to the support cylinder 24 after molding, and in that state it can be attached to the container A1, It is extremely convenient for handling.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 7 show an example of a pump refill container A (hereinafter referred to as a refill container A). The refill container A includes a container body A1 and a closure A2.

  The container A1 is formed of a synthetic resin or the like, and the mouth-and-neck portion 12 is erected from the cylindrical trunk portion 10 via the shoulder portion 11. The upper end portion of the mouth / neck portion 12 is formed in a reduced diameter portion 12a, and a locking protrusion 13 is provided around the upper end portion. Further, a male screw 14 is provided around the outer periphery of the mouth / neck portion 12 below the reduced diameter portion 12a.

  The closure A2 is integrally formed of synthetic resin, and is fitted and fixed to the container body A1 by fitting the mounting cylinder 20 on the outer periphery of the mouth-and-neck portion 12, and the inner surface of the mounting cylinder 20 is engaged. The protrusion 21 is moved over and engaged with the locking protrusion 13 on the outer surface of the mouth-and-neck portion 12 to prevent the protrusion. Further, from the lower surface of the inner peripheral edge of the flange 22 that extends inward from the upper end of the mounting cylinder 20, a seal tube portion 23 that is closely fitted to the inner periphery of the mouth neck 12 is suspended, and from the upper surface of the inner peripheral edge of the flange 22. The support cylinder 24 is erected. A protrusion 25 for pull-ring locking is provided on the upper end of the outer periphery of the support cylinder 24.

  A plurality of elastic plates 26 project from the upper inner surface of the seal cylinder portion 23. A plurality of elastic plates 26 project radially from each other through a slight slit d adjacent to each other, and gradually descend from the inner surface of the seal cylinder 23 to define a window 27 in the center. . The elastic plates 26 are not necessarily limited to those that gradually descend inward, but may be formed horizontally.

  Further, a closing plate 28 is stretched over the upper inner surface of the support cylinder 24. The closing plate 28 is configured to be cut off by connecting the outer peripheral lower end edge to the inner peripheral upper end edge of the support cylinder 24 through a thin broken portion 29. Therefore, in the illustrated example, the closing plate 28 is supported in a state protruding from the upper surface of the support cylinder 24 at a position above it. Further, the closing plate 28 may be any one in which the inside and outside of the mouth / neck portion 12 is cut off and hung on the support cylinder 24 standing above the seal cylinder portion 23, and the size and shape thereof are the pipe B3 of the pump B or Various sizes and shapes can be selected as long as the cylinder B2 can be inserted. When the closing plate 28 is smaller than the inner diameter of the support tube 24, a flange is extended from the support tube 24, and the closing plate 28 may be connected to the inner periphery of the support tube 24 via a fracture portion.

  Further, a pull ring 30 for removing the closing plate 28 is detachably fitted to the outer periphery of the support cylinder 24. The pull ring 30 is provided with a protrusion 31 for engagement at the lower part of the inner periphery excluding the rear part. The protrusion 31 for engagement is removably engaged with the protrusion 25 for pull ring locking on the outer periphery of the support cylinder 24. It is combined. Further, the pull ring 30 and the closing plate 28 are integrally connected by a flexible connecting band 32, and in the illustrated example, a protrusion 33 for hooking a finger is provided on the front surface of the pull ring 30 to face it. The rear part of the pull ring 30 and the rear part of the closing plate 28 are integrally connected by a connection band 32. In this example, a trapezoidal window hole is formed in the rear portion of the pull ring 30 for molding reasons.

  Since the closure A2 in this example is integrally formed of synthetic resin, it is initially formed with the pull ring 30 supported by the coupling band 32 at the upper position of the support cylinder 24 as shown in FIGS. I am letting. When mounting on the container body A1, for example, the engaging protrusion 21 of the mounting cylinder 20 gets over and engages with the locking protrusion 13 of the mouth-and-neck portion 12 to prevent the reduced diameter portion 12a from coming out. After the fitting, the pull ring 30 is pushed down to engage the engaging protrusion 31 with the pulling ring locking protrusion 25, and is removably fitted to the support cylinder 24, and attached as shown in FIG. Note that the container body A1 may be attached to the container body A1 in which the pull ring 30 is previously attached to the support cylinder 24.

  When the refill container A configured as described above is used, for example, the protrusion 31 for engagement of the pull ring 30 is pushed up by placing a finger on the protrusion 33 for hooking from the state shown in FIG. The pulling ring 30 is removed from the 24 pull ring locking protrusions 25, and then the pull ring 30 is pulled obliquely forward, whereby the breakage portion 29 of the closing plate 28 is cut through the connecting band 32, and the closing plate 28 is removed. After that, the pump B is mounted from above.

  The pump B is of a known mechanism including a mounting cap B1, a cylinder B2, a pipe B3, an operating member B4, and the like. A female screw 51 is provided around the inner periphery of the peripheral wall portion 50 of the mounting cap B1, and the upper end of the cylinder B2 is fixed to the upper portion of the inner periphery of the mounting cap B1. The upper end of the pipe B3 is fitted to the lower end of. In addition, the operating member B4, which is mounted in the cylinder B2 so that it can move up and down in an upward biased state, has a discharge head 71 with a nozzle 70 constituting the upper end, and the lower part slides in the cylinder B2. And a known mechanism linked to an annular piston (not shown).

  Then, as shown in FIG. 6, a pipe B3 is inserted from above the refill container A from which the closing plate 28 is removed, and each elastic plate 26 is expanded and pushed down by the pipe B3 and the cylinder B2 that are sequentially passed through the window 27. Then, the mounting cap B1 is screwed onto the outer periphery of the mouth neck portion 12 and the pump B is mounted on the container body A1 as shown in FIG. When detaching, it can be easily removed by removing the mounting cap B1 from the state of FIG. 7 and pulling up the cylinder B2.
