Description

  The present invention relates to a structure of a feeding container cap that projects solid contents from a container.

A feeding container used for solid glue, lipstick, and the like stores a solid material solidified in a rod shape in a cylindrical shaft body, which is sequentially fed out by a predetermined feeding mechanism as necessary.
The feeding container generally has a circular cross section, and the tail plug (knob portion) and cap are also formed in a circular cross section. Some of the tail plugs and caps are formed with knurls and grooves made of irregularities along the axial direction from the viewpoint of design and operability.

  When this type of container is placed on a flat surface such as a desk, it rolls by itself and sometimes falls. For this reason, in Japanese Utility Model Laid-Open No. 5-029979 (see Patent Document 1), a plurality of flat surfaces along the axial direction are formed on the outer surface of the tail plug of the feeding container to improve the finger contact during the feeding operation. In addition, a device having a function of preventing rolling is disclosed.

  In addition, this type of container has a problem that the contents are hardened inside the cap, which causes sticking and makes it difficult to remove the cap. In the invention described in Patent Document 1, the problem relating to the difficulty of removing the cap still remains even if the contents can be easily fed out and the container can be prevented from rolling.

  On the other hand, Japanese Patent Application Laid-Open No. 2002-086989 (see Patent Document 2) discloses a feeding container main body and a cap having a quadrangular shape.

  Although it can be said that this shape has some effect in terms of preventing rolling, since the center of gravity of the main body is located near the bottom of the cap, a movement occurs in which the main body shaft rotates around the cap when not in use. Therefore, it must be said that it is insufficient from the viewpoint of preventing rolling.

  In addition, the inner surface of the rectangular cap is also rectangular, and the tip of the feeding container that fits into the cap is also rectangular. Objects easily adhere to the cap part, and there is a problem in terms of hygiene.

Japanese Utility Model Publication No. 5-029979 JP 2002-086989 A

  The present invention prevents rolling of the feeding container main body and at the same time makes the main body easy to grip as in the prior art. An object is to provide a cap that can be easily removed with a small force.

  In order to solve the above-mentioned problem, the present invention is a cap for a feeding container for projecting solid contents from a container, and a bulge projecting outward in the axial direction on the side surface of the cap. It has the part.

  According to the feeding container cap of the present invention, as compared with the conventional cap, the rolling prevention effect at the time of horizontal placement is enhanced and the removal can be performed with a small force. In addition, since a special structure is not required for the main body of the feeding container, the conventional feeding container having a shape that is easy to grip can be used as it is.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to what shows the same member and the same location.

  FIG. 1 is a view showing an entire feeding container 2 in a state where a cap 1 according to the present invention is attached. Solid glue is accommodated in the feeding container 2.

  The feeding container 2 is a conventional product as it is, and is made of a hard resin such as polypropylene having a draft of about 55.0 mm, a lower end inner diameter of about 13.2 mm, and an upper end inner diameter of about 13.6 mm. At the rear end, a tail plug 3 is rotatably mounted. In the feeding container 2, the glue as the contents is fed out by a screw rod (not shown) and a slider screwed into the screw rod and fitted in the feeding container 2 so as to be movable up and down. ing. In carrying out the present invention, the structure of the feeding container 2 is not particularly limited, and can be applied to any conventional feeding container 2.

  The structure of the cap 1 according to the present invention will be described. FIG. 2 shows a plan view and an axial sectional view of the cap 1. As shown in FIG. 2, one end of the cap 1 has an opening 4 attached to the feeding container 2, and the outer shape of the one end is substantially the same as the outer shape of the feeding container 2.

  On the other hand, the other end of the cap 1 has a “drop-shaped” shape in plan view. The cap 1 has a “drop-shaped” shape on one side surface of the cap 1 from the one end to the other end. The bulging part 5 which protrudes gradually toward is formed. The bulging portion 5 is integrally formed when the cap 1 is formed. However, after the cylindrical cap and the bulging portion are separately formed, they may be integrated with an adhesive or the like. Moreover, although the cap 1 and the bulging part 5 are shape | molded, for example with a polypropylene resin, a polyethylene resin, etc., resin other than this and other materials may be sufficient. The protruding amount (height and width) of the bulging portion 5 may be appropriately determined in consideration of design and practicality as well as both the anti-rotation function and the opening operability function provided by the present invention. . If the design and the touch per finger are ignored, the bulging portion may be a rectangular or trapezoidal cross section instead of the “droplet type” (see FIGS. 7 and 8).

  FIG. 3 is a diagram illustrating a state in which the cap is in contact with the table top surface when the feeding container 2 equipped with the cap 1 is placed on the table. As apparent from FIG. 3, the bulging portion 5 of the cap 1 having a drop shape is in contact with the table top surface and has a stopper function for preventing the rotational movement of the feeding container 2.

  Moreover, even if the feeding container 2 falls from the table top to the floor surface, the bulging portion 5 does not roll more than necessary on the floor surface.

  FIG. 4 is a reference diagram when the cap 1 is removed from the feeding container 2. In particular, when the cap and the feeding container body are fitted with a screw type, the touch per finger is good by pressing the bulging portion 5 of the cap 1 having a drop shape and a smooth curved surface with the thumb of one hand. Since the cap can be easily opened, it can be opened easily even with a small force according to the principle of leverage without making the hands dirty. Although not particularly limited in the present invention, the cap 1 and the feeding container 2 may be fitted by surface friction between them, or may be fitted in a concavo-convex manner. As described above, the screw type can be opened more easily with one hand.

  In the above embodiment, an example in which the bulging portion 5 is provided in the cap 1 having a circular cross section in accordance with the external shape of the feeding container 2 has been described, but the cap 1 may have a polygonal cross section. Further, it may not be the same as the outer cross-sectional shape of the feeding container 2. In addition, the cross-sectional shape of the fitting portion between the cap 1 and the feeding container 2 is not particularly limited, but in order to maximize the “easy removal of the cap”, the inner surface of the cap 1 and the tip outer shape of the feeding container 2 are It is desirable that they are fitted in a circular shape.

  In the above embodiment, an example in which one bulging portion 5 is provided in the cap 1 to form a “drop-shaped” in a plan view is shown. However, two or three or more bulging portions 5 are provided. Also good. The number and the shape are not limited as long as the bulging portion prevents the rotation of the feeding container 2 on the table and exhibits the function of easily opening the cap 1 with one hand. FIG. 5 shows an example having three bulging portions 5.

  Moreover, in the said Example, although the bulging part 5 is made into the structure which protrudes gradually toward the other end from the one end of the cap 1, as shown to FIG. 6, FIG. A structure having the same width may be used. Further, as shown in FIGS. 7 and 8, the cross-sectional shape of the bulging portion 5 is not limited to the drop shape, but may be a rectangle, a trapezoid, or the like as long as the touch per finger is ignored.

  Moreover, in the said Example, although the bulging part 5 which continued from the axial direction one end to the other end of the cap 1 was formed, even if it forms in a part (between one end and the other end) of a cap side surface. Good (see FIGS. 9, 10 and 11).

  Moreover, in the said Example, although the bulging part 5 is formed solidly with resin, it is good also as a hollow structure. In that case, a cap may be covered from the other end of the cap 1 to hide the hollow portion, or the cap 1 may be left hollow.

  The cap according to the present invention is not limited to the solid paste feeding container shown in the embodiments, but can be applied to various feeding containers such as lipstick and lip balm.
