Description

The present invention relates to a refill container for containing a liquid content for refill.

  Conventionally, in containers that store various contents such as cosmetics and foodstuffs, from the viewpoint of effective use of resources, a refill container (a container that refills the contents stored in itself into another container) ) And refilling only the contents so that the container itself can be used continuously. As such a refill container, a container as shown in FIG. 10 has been proposed. The container includes a container main body 31 and a cap 32 that is screwed onto the neck 31a of the container main body 31, and the container main body 31 is divided into two vertically at the upper end portion of the body portion 31b, and a lower divided portion thereof. 33 (a portion of the body portion 31b excluding the upper end portion) and an upper divided portion 34 (a portion including the upper end portion of the body portion 31b and the neck portion 31a) are screwed together (see FIG. 11).

  In FIG. 11, 33a is a thread portion formed on the outer peripheral surface of the upper end opening portion of the lower divided portion 33, and 34a is formed on the inner peripheral surface of the lower end opening portion of the upper divided portion 34. This is a threaded portion that is screwed into the threaded portion 33a of 33. Reference numeral 32a denotes a screw portion formed on the inner peripheral surface of the lid body 32, and reference numeral 31c denotes a screw portion formed on the outer peripheral surface of the neck portion 31a of the container body 31 and screwed into the screw portion 32a of the lid body 32. is there.

  And when accommodating the contents for refilling (not shown) in the container main body 31, after accommodating the contents in the lower divided part 33 in the state which divided | segmented both the said divided parts 33 and 34, the said Both the divided parts 33 and 34 are screwed together. Further, when refilling the contents in the body part 31b into another container (not shown), the cap 32 is removed from the neck part 31a of the container body 31, and the contents are poured out from the spout 35 of the neck part 31a. Pour into the spout of another container.

  However, in the above container, when the contents are refilled into another container, there is a possibility that both the divided parts 33 and 34 are mistakenly divided and the contents are discharged to the outside. Moreover, when the cap 32 is rotated in the opening direction when the contents are refilled, the upper divided portion 34 is also rotated in the opening direction by this rotational force. Therefore, when the refilling of the contents is repeated, There is a risk that the screw connection between the two divided portions 33 and 34 is loosened with the rotation, the two divided portions 33 and 34 are divided, and the contents flow out to the outside.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a refill container that does not accidentally open the inner stopper and that does not loosen even if the cap is repeatedly opened.

In order to achieve the above object, the refill container of the present invention comprises a bottomed cylindrical container main body in which the liquid content for refill is accommodated , and a cap screwed onto the lower part of the neck of the container main body , and plug in the downward cup shape having a spout that is freely fitted removably to the top of the neck portion of the container body, and a stopper portion which plug the spout, a refill container and a rib, said plug The part is composed of a cylindrical upper plug part that hangs down from the inner ceiling surface of the cap, and a cylindrical lower plug part that has a smaller diameter than the upper plug part that hangs down from the cylindrical lower surface of the upper plug part. The inner plug has any one of a first inner plug having a spout corresponding to the lower plug portion of the plug portion and a second inner plug having a spout corresponding to the upper plug portion of the plug portion. An annular structure composed of one side, the rib projecting downward from the ceiling surface of the cap It is configured, a configuration that its lower wall in closed state is in contact with the shape fitted to the upper small-diameter portion in said plug.

That is, in the refill container of the present invention, when the liquid content for refilling is to be accommodated in the refill container, the cap screwed to the lower part of the neck part of the container body is removed by rotating in the opening direction. Remove the inner plug from the top, and in that state, let the contents flow into the body from the top opening (ie, spout) of the neck, and then fix the inner plug to the upper part of the neck, and to the lower part of the neck The cap is screwed to cover the top of the neck and the inner plug. In addition, when refilling the contents in the body part into another container, the cap screwed to the neck part of the container body is removed by rotating in the opening direction, and the contents are poured out from the spout of the neck part. Inject into the spout of the container.

  Thus, in the refill container of the present invention, the upper part of the neck part and the inner plug are covered with a cap screwed to the lower part of the neck part of the container body, and when the contents are refilled to another container, It is only necessary to rotate it in the opening direction and remove it from the lower part of the neck. For this reason, when refilling, the inner plug is mistakenly removed from the upper part of the neck and the contents are not allowed to flow out. Moreover, even if the cap is rotated in the opening direction at the time of refilling, since this rotational force does not act on the inner plug, even if the refilling is repeated, the inner plug will come off from the upper part of the neck and the contents will remain. There is no leakage to the outside.

  In the present invention, when a plug portion that plugs the spout of the inner plug is projected downward from the ceiling surface of the cap, by screwing the cap to the lower portion of the neck portion of the container body, The spout of the inner plug can be plugged with the cap portion of the cap.

  Further, in the present invention, the plug portion is provided with an upper plug portion projecting downward from the ceiling surface of the cap, and a lower plug having a smaller diameter than the upper plug portion projecting downward from the lower surface of the upper plug portion. And when the outlet of the inner plug is formed in a shape corresponding to the upper stopper or the lower stopper, the outlet corresponds to the upper stopper as the inner stopper. Two types, one with a shape and one with a shape corresponding to the lower plug part, are prepared. Depending on the type of contents, the above two types of inner plugs can be used properly. The same cap can be used for the stopper.

  Next, the best mode for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

FIG. 1 shows an embodiment of a refill container according to the present invention. In the figure, reference numeral 1 denotes a container body (see FIG. 2) in which a liquid content (refillable liquid content) 2 such as a refill lotion is accommodated, and is formed in a bottomed cylindrical shape (FIG. 3). reference). More specifically, as shown in FIG. 1 , the container body 1 includes a bottomed cylindrical body 11 in which the content 2 (see FIG. 1) is accommodated, and a shoulder (i.e., the body 11). A cylindrical neck portion 12 erected from the inner peripheral portion of the annular upper wall 11a) of the trunk portion 11 is provided. Further, the lower portion of the neck portion 12 is formed to have a larger diameter than the upper portion of the neck portion 12, and a cylindrical cap support portion 13 is constituted by the large diameter portion, and at the upper portion of the neck portion 12. A cylindrical inner plug support portion 14 is configured. The upper opening of the cap support 13 and the lower opening of the inner plug support 14 are connected by an annular connecting part 15.

  The cap support portion 13 is formed with a screw portion 13a that is screwed into a screw portion 21a of the cap 4 described later on the outer peripheral surface thereof, and the inner plug support portion 14 has an outer peripheral surface thereof. An annular engagement convex portion 14a that detachably engages with an engagement convex portion 16a of the inner plug 3 to be described later is projected. The neck 12 has a wide opening, and the diameter of the upper surface opening is set to about 25 to 50 mm.

  Reference numeral 3 denotes a first inner plug that is supported by the inner plug support portion 14, and as shown in FIGS. 5 to 7, a cylindrical lower portion that is detachably supported by the inner plug support portion 14. Side large-diameter portion 16 (this lower large-diameter portion 16 has flexibility), a cylindrical upper small-diameter portion 17 having a spout 17a formed in its own ceiling portion, and the lower side The upper end opening part of the large diameter part 16 and the lower end opening part of the upper small diameter part 17 are configured by an annular connection part 18.

  The lower large-diameter portion 16 is provided with an annular engagement convex portion 16a that detachably engages with the engagement convex portion 14a of the container body 1 at the lower end portion of the inner peripheral surface thereof. A removal flange 19 projects from the lower end of the outer peripheral surface. The upper small-diameter portion 17 has an annular ridge 17b protruding from the upper end portion of the outer peripheral surface thereof so as to abut on the rib 23 of the cap 3 in an inner fitting manner. The connecting portion 18 is provided with a cylindrical protrusion 18a on the lower surface thereof so as to abut on the inner plug support portion 14 in an inner fitting manner.

  Reference numeral 4 denotes a cap formed in a celestial cylindrical shape, and the neck 12 and the first inner plug 3 are covered with the cap 4 in a closed state. The cap 4 has a threaded portion 21a formed on the inner peripheral surface of the peripheral side wall 21 to be screwed with the threaded portion 13a of the cap support portion 13 of the container body 1. The cap 4 is plugged from the ceiling surface. The part 22 protrudes downward. The plug portion 22 includes a cylindrical upper plug portion 22a protruding from the ceiling surface, and a lower plug portion 22b protruding from the lower surface of the upper plug portion 22a and having a smaller diameter than the upper plug portion 22a. The lower plug portion 22b functions to plug the spout 17a of the first inner plug 3 in the closed state. The upper plug portion 22a functions to plug a spout 17a of the second inner plug 5 described later in a closed state.

  Further, the cap 4 is provided with an annular rib 23 projecting downward from the ceiling surface, and abuts against the protrusion 17b of the upper small diameter portion 17 in a closed state. The outer periphery of the rib 23 is supported by a plurality of reinforcing plates 24.

  As shown in FIG. 8, the second inner plug 5 has an upper small-diameter portion 17 formed higher than the upper small-diameter portion 17 of the first inner plug 3, and a spout 17 a is formed on the cap portion 22 of the cap 4. It is formed in a shape corresponding to the upper plug portion 22a (a shape that can plug the spout 17a in the closed state) (see FIG. 9). The other parts are the same as those of the first inner plug 3, and the same parts are denoted by the same reference numerals. Such a first inner plug 3 is used when the content 2 has a low viscosity such as a lotion, and the diameter of the spout 17a is set to about 1 to 1.5 mm. Moreover, the 2nd inside plug 5 is used when the content 2 is a thing with high viscosity, such as milk, and the diameter of the spout 17a is set to about 3-6 mm.

  In the above configuration, when the contents 2 for refilling are accommodated in the body portion 11 of the container body 1, the cap 4 screwed into the cap support portion 13 of the neck portion 12 of the container body 1 is opened in the opening direction.
