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. Also, if the replacement container with the tip cut off is accidentally turned down, a large amount of liquid may be leaked.

  In the latter case, replacement is relatively troublesome, and if the container is accidentally tilted at the time of replacement, a large amount of liquid may be leaked. It is also possible to easily refill the liquid in the container by removing the pump.

  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 an elastic plate 24 that protrudes radially from the seal cylinder portion 23 in a circumferential direction through a slight slit-like gap. ... and the inside and outside of the mouth-and-neck portion 12 are cut off and the elastic plates 24 are placed over the upper positions and provided with an annular break line 27 so as to be cut off, and the closure plate 26 within the break line 27 It is equipped with a handle that stands up and a protective means that protects the influence of external force on the handle, and is formed integrally with synthetic resin so that the elastic plates 24 are gradually lowered inward. From the upper side where the removal plate portion 26a is removed, the elastic plate 24... Linda B2, characterized by mounting the pump B Push down while expanding the elastic plate 24 ... a.

The second means is configured as follows. That is, in the first means, the handle is configured by extending the pull ring 29 on the upper portion of the support 28 standing on the closing plate 26 in the breaking line 27.

The third means was configured as follows. That is, in any one of the first means and the second means, the protection means is provided so as to be able to be opened and closed by covering the handle, and an easily cutable cutting portion 46 is provided at the connecting portion. The lid 40 is provided.

The fourth means is configured as follows. That is, in any one of the first means and the second means , the protection means is configured by standing a protection wall 34 having a height higher than the handle surrounding the handle periphery.

  According to the present invention, it is a simple structure in which a closure A2 integrally formed of a synthetic resin is fitted to a normal container body A1, and since the normal container body A1 can be used, it is versatile. It has the advantage of being rich and inexpensive to manufacture. In use, for example, the closure plate 26 can be cut and removed simply by grasping and pulling the handle, and can be replaced by a simple operation of installing the pump B removed from the used container. It is extremely simple. Furthermore, since each of the adjacent elastic plates 24 is provided with a plurality of radially projecting circumferentially through slit-shaped slight gaps d, even if the container is accidentally tilted after opening, The amount of leakage can be made as small as possible, and there is an advantage that leakage can be almost prevented particularly when the stored liquid has a high viscosity. Further, it is difficult to quickly inject the liquid due to the presence of the elastic plates 24, and therefore, mischief such as refilling of the liquid can be prevented as much as possible.

  In addition, since a protective means for protecting the influence of external force on the handle standing on the closing plate 26 in the breaking line 27 is provided, a part of the breaking line 27 is accidentally broken by the external force before replacement. Etc. can be prevented. Furthermore, since it can be integrally formed with a synthetic resin, there is also an advantage that it can be manufactured at a low cost.

  When each of the elastic plates 24 is configured to gradually descend inward, when the pump B is mounted, the elastic plate 24 is easily elastically deformed so that the whole is rotated downward by the pipe B3 and the cylinder B2. Further, 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 die can be removed more naturally at the time of manufacture due to the presence of the closing plate 26 thereabove.

  When the above handle is constructed by extending the pull ring 29 on the support column 28 standing on the closing plate 26 in the breaking line 27, even if the height is lowered as much as possible, the closing in the breaking line 27 is efficiently performed. The plate 26 can be removed, and as a result, the height of the protective means can be made as low as possible, leading to savings in material costs.

  When the protective means is provided by covering the handle so that it can be opened and closed, and by providing the lid 40 with the easily cuttable cutting portion 46 at the connecting portion, the handle can be reliably protected, and In addition, since a simple operation of pulling and cutting the lid 40 is added during the operation, the replacement operation can be easily performed without changing.

  If the protective means is constructed by standing up the protective wall 34 that is taller than the handle around the handle, the structure is simplified, leading to savings in material costs and more replacement operations. It becomes simple.
