Description

  The present invention relates to a liquid ejection container capable of efficiently taking out contents by raising a middle dish of the container body, and is a technique for confirming the remaining amount of contents.

  If the container is provided with a light-shielding property for the purpose of maintaining the quality of the contents, the container main body becomes opaque, so that it is impossible to visually check the remaining amount of the contents.

In contrast, a conventional liquid ejection container uses a tape with an identifier near the end, and the tape is wound around a bottom member that closes the lower end of the body of the container body so that the tape can be pulled out. There is one that is connected to the lower end of the plate and is visible from a window provided on the bottom member using the identifier of the tape as an indicator (display unit) (for example, see Patent Document 1).
JP 2007-217038 A

  However, since the conventional container employs a wound tape as an indicator, the configuration becomes complicated, and there is room for improvement in terms of productivity and cost.

  In addition, since it is a wound tape, for example, if the winding of the tape is loose, it is considered that the tape cannot be pulled out smoothly. Further, since the tape is pulled out from the wound state, the tapes may be caught.

  In such a case, since the tape comes off from the inner pan or breaks, the function as an indicator cannot be exhibited. In addition, when the tape does not come off or breaks, the movement of the inner plate is regulated by the tape, so that the original function of the inner plate may be damaged in the worst case.

  An object of the present invention is to provide a novel liquid capable of confirming the remaining amount of contents with a simple configuration without impairing the original function of the intermediate dish even when the indicator is associated with the intermediate dish and the bottom member. The object is to provide an ejection container.

The liquid ejection container according to the present invention includes a container body having a mouth portion for filling contents, and a lower end of the body portion closed by a bottom member, a pump attached to the mouth portion of the container body, and an operation of the pump In a liquid ejection container comprising a nozzle head from which the contents are taken out and a middle plate that is slidably disposed inside the trunk of the container body and rises as the contents are taken out,
A plurality of intermittently formed annular slits are formed concentrically between the intermediate dish and the bottom member, and a sheet member that can be extended by lifting its center or outer edge is disposed,
While fixing one of the center and the outer edge of the sheet member to the lower end of the middle dish, while holding the other of the center and the outer edge of the sheet member detachably from the bottom member,
The bottom member is provided with a window portion through which a sheet member can be visually recognized in an extended state and a detached state thereof.

  The sheet member according to the present invention preferably holds the outer edge of the sheet member while fixing the center to the lower end of the intermediate dish.

  In this case, it is preferable that the outer edge of the sheet member is detachably held by a ring member fixed to the bottom member.

  In this case, the center of the sheet member is preferably connected by a pin member that passes through the sheet member and fits into the inner tray.

  Each of the annular slits is preferably arranged with a phase difference of 90 degrees with respect to the intermittent portions of the adjacent annular slits whose intermittent portions are arranged concentrically.

  Moreover, it is preferable to comprise the edge part of an annular slit as a round hole for preventing the fracture | rupture of the intermittent part.

  In addition, when the window part which concerns on this invention is comprised with the material which consists of transparent or semi-transparent which can see through the whole bottom member, for example, the part except a window part is covered with a light-shielding film, or a window part is covered. It can be formed by leaving a mask coating. Further, the portion of the bottom member excluding the window portion may be made of an opaque material, while the window portion may be made of a transparent material and assembled to each other. Further, the bottom member may be integrally formed of a transparent material and an opaque material.

  According to the present invention, as the center or outer edge of the sheet member is lifted as the middle plate rises, the sheet member extends so as to move away from the bottom member. By visually observing the change, the remaining amount of the contents can be reliably confirmed.

  In addition, in the present invention, since the sheet member is detachably held from the bottom member, for example, if the sheet member is configured to be detached when the inner tray reaches the top dead center, the sheet member is The time of replacement can be confirmed by detaching from the bottom member and making it invisible from the window.

  Moreover, since the indicator of this invention is a simple structure of forming a slit in the sheet | seat member which connects between an inner tray and a bottom member, it is excellent in productivity and cost efficiency.

  In addition, the extension of the sheet member is realized by sequentially lifting a part of the sheet member concentrically in accordance with the annular slit formed intermittently with respect to the sheet member. It does not occur and smooth extension can be realized.

  Therefore, according to the present invention, even if the indicator is associated with the middle dish and the bottom member, a novel liquid jet that can confirm the remaining amount of the contents with a simple configuration without impairing the original function of the middle dish. A container can be provided.

  In particular, if the annular slits are arranged so that the intermittent portions thereof have a phase difference of 90 degrees with respect to the intermittent portions of the adjacent annular slits arranged concentrically, the sheet member is evenly spaced from the bottom member. Further, the remaining amount of the contents is accurately measured, so that more reliable remaining amount confirmation can be realized.

  Further, if the end portion of the annular slit is configured as a round hole for preventing breakage of the intermittent portion, a more reliable remaining amount confirmation can be realized without the sheet member breaking along with its extension.
