JP5199175B2 - Metering stopper - Google Patents

Description

  The present invention relates to a metering stopper suitable for taking out and applying a predetermined amount of contents in a container.

  For products with a fixed amount of use, such as a chemical solution such as a hair restorer, it is necessary to weigh when taking out the contents in the container. Conventionally, the cylindrical part arranged on the inner plug is moved up and down appropriately. By alternately opening and closing the first valve and the second valve, the contents in the container are poured into the measuring cylinder and weighed, and the contents in the measuring cylinder are discharged outside through the spout and used. (For example, see Patent Document 1).

JP 2002-337910 A

  By the way, this kind of conventional quantitative dispenser is easily slid when an unintentional force is applied to the body during the dispensing of contents related to weighing, and the container and the measuring tube In this case, there is a problem that more than necessary contents flow into the measuring cylinder and cannot be dispensed quantitatively. In the case of applying, it is usually applied using a separately prepared applicator, and it is not easy to use, and there is still room for improvement.

  An object of the present invention is to propose an easy-to-use metering stopper that can accurately measure the contents under a simple structure and that can directly apply the contents for measurement.

The present invention has an outer cylinder that stands up at the mouth of a container, a cap base that is fixedly held at the mouth, and is retained by the outer cylinder of the cap base so that its tip is directly applied to the application surface. An application head for applying the contents in the container in contact with the overcap, and an overcap covering the application head,
The coating head has a slit that is opened by contact with the coating surface, and includes a cylindrical body that forms a measurement space for contents inside the rear end portion as an open end,
Provided on the bottom wall of the cap base is a convex partition that is located inside the cylindrical body of the coating head and has at least one opening that allows the contents in the container to flow into the measuring space of the coating head. ,
The cylindrical body of the coating head is slidably inserted between the peripheral wall of the convex partition wall and the outer cylindrical body of the cap base so that the coating head slides toward the bottom wall of the cap base. A metering plug having an annular groove that closes the opening and opens the opening by sliding away from the bottom wall of the cap base when the overcap is removed. As the coating head, one having an annular bulging portion on the upper outer wall of the cylindrical body is particularly desirable.

  When removing the overcap, the opening provided in the partition wall is opened by pulling up the coating head, so the contents flow into the measuring space formed inside the coating head by reversing the container, and the operation Only the weighing can be completed.

  In addition, when the coating head is brought into direct contact with and pressed against the coating surface after weighing, the coating head slides toward the bottom wall of the cap base to close the opening, while the top wall of the coating head is elastic. When the slit provided in the top wall portion is deformed and the contents relating to the measurement flow out toward the application surface, the application can be performed as it is.

It is the figure which showed embodiment of the coating stopper according to this invention. It is the figure which showed the state which removed the overcap in the coating stopper shown in FIG. It is the figure which showed the use condition of the coating stopper shown in FIG.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a view showing an embodiment of a metering spout according to the present invention in a state of being attached to the mouth of a container, and FIG. 2 is an enlarged view of a main part in a state where an overcap is removed.

  In the figure, 1 is a cap base. In the cap base 1, a base portion 1a forming a bottom wall portion thereof is fixed and held at the protruding end portion of the mouth portion 2 of the container by an engaging means such as an undercut (it may be engaged by a screw). 3 is an outer cylindrical body that is integrally connected to the cap base 1 and stands above the mouth portion 2 of the container, and 4 is made of a soft material or the like, and is applied to the outer cylindrical body 3 that is integrally connected to the cap base 1. Head. The application head 4 applies the contents in the container with its tip portion in direct contact with the application surface. The top wall 4a, which can be elastically deformed by pressing, has a concave in the center. A single-letter-shaped or cross-shaped slit S that is opened by contact and pressing on the coating surface is formed. An open end 4c is provided at the rear end of the cylindrical body 4b connected to the top wall 4a, and an annular bulge 4d is provided at the upper end of the cylindrical body 4b.

  The cylindrical body 4b of the coating head 4 is composed of a small diameter portion and a large diameter portion, and a measuring space M is formed inside thereof, and a step portion t formed at the boundary between the small diameter portion and the large diameter portion. Comes into contact with an annular claw portion 3 a provided at the front end opening of the outer cylinder 3 of the cap base 1, so that the coating head 4 is prevented from coming off in the outer cylinder 3.

  Reference numeral 5 denotes a protruding partition wall that is integrally provided on the base 1 a that forms the bottom wall of the cap base 1. The partition wall 5 is located inside the cylindrical body 4b of the coating head 4, and includes an annular peripheral wall 5a and a ceiling wall 5b connected to the upper end of the annular peripheral wall 5a. In the place, a plurality of openings 5c formed at intervals along the periphery thereof are provided.

  Furthermore, 6 is an annular groove formed between the annular peripheral wall 5 a of the partition wall 5 and the outer cylinder 3 of the cap base 1. The annular groove 6 allows the cylindrical body 4b of the coating head 4 to be slidably inserted with an appropriate frictional resistance, and slides toward the base 1a (bottom wall portion) of the cap base 1 of the coating head 4. While the opening 5c is closed by the inner peripheral wall (see FIG. 1), the opening 5c is opened by sliding in a direction away from the base 1a of the cap base 1. Here, the appropriate frictional resistance can be slid with a relatively small pressing force or tensile force, but in a state where the pressing force or tensile force is removed, the coating head 4 can be stopped at that portion. Such frictional resistance shall be referred to.

  Reference numeral 7 denotes an overcap that houses the coating stopper and is screwed (or may be engaged by undercutting) at the neck of the container. The overcap 7 includes a peripheral wall 7a that surrounds the coating plug, and a top wall 7b that is integrally connected to the upper end of the peripheral wall 7a to form a storage space inside thereof. A hanging cylinder 7c that is elastically fitted to the four bulging portions 4d is provided. When the overcap 7 is removed, the drooping cylinder 7c has such a fitting strength that the coating head 4 can be pulled upward to open the opening 5c formed in the partition wall 5.

  In the state shown in FIG. 1 with the overcap 7 attached, the coating head 4 is positioned such that its open end 4c abuts the lower end of the annular groove 6, and the opening 5c of the partition wall 5 is In the state surrounded by the inner peripheral wall of the cylindrical body 4b of the coating head 4 (closed state), the contents in the container do not flow out into the measuring space M even if the container is inverted.

  When the overcap 7 is removed, the coating head 4 slides in the annular groove 6 and is lifted as shown in FIG. 2, thereby opening the opening 5c. In this state, the coating head 4 remains in a position as it is due to an appropriate frictional resistance.

  When the container is inverted in this state, the contents in the container flow into the measurement space M, and the measurement is completed in a state where the measurement space M is filled with the contents.

  When the application head 4 is pressed against the surface to be applied such as the scalp in a state where the measurement is completed, the application head 4 slides toward the base 1a of the cap base 1 as shown in FIG. The opening 5c is blocked (closed), and the content in the measuring space M flows out to the application surface through the slit S, and the content is obtained by inducing an appropriate application operation of the application head 4 here. Can be applied uniformly.

  The application plug according to the present invention can discharge and apply an appropriate amount of content by simply pressing the application nozzle against the surface to be applied after removing the overcap 7 and inverting the container. Troublesome operation is unnecessary, and usability is very good.

  In addition, since the coating plug is composed of two members, that is, a coating head and a cap base that holds and holds the coating head, the structure can be simplified and efficient manufacture can be performed.

  All the constituent members constituting the coating plug can be made of synthetic resin, but the coating head 4 can be made of a material such as rubber or elastomer, and this point is not particularly limited.

  It is possible to provide an application stopper having a simplified structure that enables measurement under a simple operation and application of contents for measurement.
