Description

[Detailed description of the device] [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin cap for a container, and more particularly to a positioning cap that can be securely fixed in a specific orientation of the container.

[Prior art]

Generally, as a liquid container for storing shampoo, conditioner, etc., not only a liquid body having a circular horizontal cross section,
A substantially elliptical shape is also widely used. And as a cap for opening and closing the spout of a container having such an irregular cross section, most caps have a simple structure in which a screw is engraved on the inner surface of a tubular body, but the spout hole is in the center. There is also a cap having a structure in which a cylindrical fixing portion having a screw on the inner peripheral surface and a makeup body are doubly hung from a perforated top wall. Although the structure of the cap having the makeup body is complicated, there is a merit that the makeup body can smoothly cover the shoulder portion of the container naturally and therefore can be excellent in design. In recent years, the amount used has increased. In the positioning cap having the above structure, it is necessary to fix the cap that is formed so as to substantially match the shape of the shoulder portion of the container in a specific direction, that is, so as to match the shoulder portion of the container. A concave portion or a convex portion which can be fitted as a positioning means is provided at an appropriate portion of the above.

[Problems to be solved by the device]

However, in the conventional positioning cap, the concave portion or the convex portion of the positioning means formed on the lower end portion of the inner surface of the makeup body is integrally formed on the thin and wide makeup body with a local significant change in wall thickness. Has been done. Each resin has its own shrinkage rate, and it shrinks during the cooling process during resin molding, so the surface is pulled due to the shrinkage of the thick part where cooling is delayed compared to the thin part, so a so-called sink mark is likely to occur. There was a problem called. For this reason, the entire outer peripheral portion of the makeup body, or the positioning means is formed to form knurls or the like in the vertical direction on the surface side portion where sink marks are likely to occur,
Even if a sink mark was generated, it was made inconspicuous. However, forming knurls etc. on the outer periphery of the makeup body is
Since it becomes a big constraint on the design, the invention of a positioning cap having a structure that does not generate a sink mark at the time of manufacturing has been awaited.

[Means for Solving the Problems]

The present invention has been made in order to solve the above-mentioned problems of the prior art, and includes a top wall having a pouring hole in the central portion, a cylindrical fixing portion hung on the lower surface of the top wall, and the cylindrical fixing portion. And a positioning member that is formed by a separate member and is fitted and fixed to the defect portion. Provided is a positioning cap, wherein the positioning support part is formed with a positioning means composed of a convex part or a concave part at a position corresponding to the concave part or the convex part provided in the mouth-neck part of the container body. To do.

[Action]

A positioning support part made of a separate member is fitted and fixed to the defect part provided in the cosmetic body part of the fixing member, and a positioning means composed of a convex part or a concave part of the positioning support part is provided at the mouth / neck part of the container body. Engages with the recessed portion or the protruding portion, whereby the cap is attached to a predetermined position (direction) of the neck portion of the container body. Moreover, since the positioning means composed of the convex portion or the concave portion is formed on the positioning support portion of another member which is fitted and fixed to the defective portion of the cosmetic body portion, the width of the positioning support portion is almost the same as the width of the positioning means. Alternatively, by designing a slightly larger member, the entire member cools substantially uniformly during resin molding, so that it is possible to prevent the occurrence of sink marks in the thickly formed positioning means forming portion.

【Example】

Next, the present invention will be described in detail based on an embodiment shown in the drawings. The illustrated positioning cap includes a fixing member 1 and an opening / closing lid member 2.
And a cap that is used by being fixed to the container 3 having a storage body having a substantially elliptical horizontal cross section. The code
Reference numeral 31 denotes a shoulder portion of the container 3, and a mouth-neck portion 32 is formed in a cylindrical shape at the central portion of the shoulder portion 31 so as to project, and the tip end portion thereof is opened and spouted.
33 is formed, and a screw 321 for screwing a positioning cap is screwed on the outer peripheral portion. Further, on the base portion on the short diameter side of the shoulder portion 31, projecting positioning means 322 are formed facing each other in order to fix the positioning cap in a predetermined direction. In the fixing member 1, a cylindrical fixing portion 12 is vertically provided from a top wall 11, and a screw 121 that can be screwed into the screw 321 of the container 3 is screwed on an inner peripheral surface of the cylindrical fixing portion 12. There is. A pouring hole 111 is formed in a central portion of the top wall 11 surrounded by the cylindrical fixing portion 12 so as to be able to communicate with the pouring port 33 of the container 3. The spout hole 111 is formed so as to project upward, and a ridge 112 is formed on the outer peripheral portion of the spout hole 111 so that the opening / closing lid member 2 can be fitted and integrated. Also, the top wall 11
Surrounding the cylindrical fixing portion 12 is a vertically extending makeup elliptical body portion 13 having a substantially elliptical opening end portion, the lower end portion of which can be smoothly connected to the shoulder portion 31 of the container 3. Is formed in. Further, a short-diameter side of the makeup body 13 is vertically opposed to a defective portion 131, and the positioning support portion 23 of the opening / closing lid member 2 is attached to the makeup body 13 having a substantially oval shape. Has been done. In the opening / closing lid member 2, the fixing member 1 exposes the spout hole 111, and the top wall 1
1, a cylindrical connecting portion 22 is hung from a substantially elliptical decorative top wall 21 that covers most of 1, and a protrusion 221 formed on the inner surface of the connecting portion 22 is formed into the protrusion of the spout hole 111. By fitting with the strip 112, the fixed member 1 and the opening / closing lid member 2 are connected and integrated. Positioning means 231 from the minor axis side of the decorative top wall 21.
A strip-shaped positioning support portion 23 that is substantially equal to or slightly wider than the above is vertically attached to the defective portion 131 of the fixing member 1 so as to be attachable. The positioning means 231 is the positioning support part 2
The lower end of the inner surface of the container 3 is formed so as to be recessed so that the positioning means 322 of the container 3 can be fitted therein. Therefore, when the fixing member 1 and the opening / closing lid member 2 are integrally connected and screwed into the mouth / neck portion 32 of the container 3, the positioning device 231 of the container 3 is fitted to the positioning device 322 of the container 3 to stop the rotation. To be made
The cap is in a specific orientation, i.e., the elliptical makeup body 13
Is fixed so as to match the direction of the substantially elliptical storage barrel of the container 3. The opening / closing lid member 2 has one end on the major axis side of an outer peripheral wall 26 vertically extending from the decorative top wall 21 via a pair of hinges 24 integrally formed and a plate-shaped spring member 25 bent in a substantially L shape. An opening / closing lid 27 is rotatably connected to the opening / closing lid 27, and a projecting sealing means 271 is provided at the center of the inner surface of the opening / closing lid 27.
Since it is formed so as to be able to infiltrate into the
It can be opened and closed freely. Further, the positioning support portion 23 is firmly attached to the defective portion 131 by fitting the protrusions 232 and the grooves 132 formed on the respective end faces. By the way, the positioning support portion 23 attached to each of the opposed defective portions 131 has a positioning means 23 at the lower end of the inner surface.
Although it is resin-molded with 1, since the member is downsized to a width almost equal to that of the positioning means 231, a cooling delay of the resin is unlikely to occur at the time of molding, and the positioning means 231 has almost no effect. No sink marks are generated on the formed surface portion. In particular, the positioning support portion 23
If you use a resin with a darker color than 13, you can make sink marks less noticeable. The positioning means 231 provided on the positioning support part 23 and the positioning means 322 for the container 3 are provided with concavities and convexities opposite to each other, and one convex part rides over the other convex part and is fixed, etc. Any structure can be used as long as it is a positioning means involving the above, and the decorative top wall 21 is omitted, and the opening / closing lid member 2 is connected to the top wall 11 of the fixing member 1 directly or by an appropriate means. I don't mind. Further, although the opening / closing lid member 2 is connected to one end on the long diameter side of the fixing member 1 in the embodiment, it may be connected to the short diameter side.

[Effect of device]

As described above, in the positioning cap according to the present invention, the positioning support portion made of a separate member is fitted and fixed to the defective portion provided in the decorative body portion of the fixing member, and the positioning support portion has the convex portion or the concave portion. The positioning means engages with a concave portion or a convex portion provided on the mouth-neck portion of the container body, whereby the cap is attached to the container body at a predetermined position. Moreover, since the positioning means is formed on the positioning support portion which is a small separate member that is fitted and fixed to the defective portion of the makeup body, the sink marks which are difficult to prevent in the conventional manufacturing of the positioning cap are completely prevented. It has become possible. In particular, if the positioning member is made of a resin having a color different from that of the decorative body, this effect can be further enhanced and the design can be made excellent.
