By gripping the portion, it becomes possible to grip the film 18 in a stable state without touching it.

In the present embodiment, the measuring cap 10 is transparent (including translucent) in which at least the inside of the liquid reservoir bulging portion 12 is visually recognizable and has preferably light transmittance such as polypropylene, polyethylene, polyethylene terephthalate, etc. ) Can be formed using synthetic resin. Specifically, first, the molten raw material resin is introduced into a mold for injection molding, and the injection cylinder portion 11, the annular rib 15, the annular wall portion 16, and the blow, which have a shape complementary to the mold, are first introduced. The preliminary bottomed cylinder portion for forming the liquid reservoir bulging portion 12 by molding is integrally molded by injection molding to form a preform. This preform is formed so that the injection cylinder portion 11, the annular rib 15, and the annular wall portion 16 have substantially the same dimensions as the injection-molded portion in the target measuring cap 10.

Next, the portion of the preform including the preliminary bottomed cylinder portion is inserted into a mold for blow molding, and the preliminary bottomed cylinder portion is blow molded, whereby the injection cylinder portion 11, the annular rib 15, and the annular wall portion are formed. It is possible to form the measuring cap 10 formed by integrally molding the injection-molded portion 19 including the 16 and the liquid reservoir bulging portion 12. Injection molding and blow molding may be performed separately, or injection blow molding in which blow molding is continuously performed after injection molding may be adopted. When performing blow molding of the liquid reservoir bulging portion 12, for example, the annular rib 15 can be used as a grip portion during blow molding.

Then, in the present embodiment, the measuring cap 10 formed as described above covers at least the entire or part of the peripheral wall portion 12a of the liquid reservoir portion (liquid reservoir bulging portion) 12 so that the inside can be visually recognized. A transparent (including translucent) region 18a is provided (see FIG. 1), and a decorative film 18 is preferably attached. In the present embodiment, as described above, the film 18 has a slightly reduced diameter region between the annular step portion 12d of the peripheral wall portion 12a of the liquid reservoir bulging portion 12 and the annular step portion 16b of the annular wall portion 16. In addition, preferably, the constricted portion 50 is covered from the outside, and the constricted portion 50 is continuously attached from the peripheral wall portion 12a to the annular wall portion 16.

As the film 18, a shrink label for decoration can be preferably used. The shrink label can be formed by using, for example, a film material made of polystyrene, polypropylene, polyethylene terephthalate, a composite thereof, or the like as a resin capable of shrinking by heating. Preferably, the film with the shrink label 18 for decoration is processed into a tubular shape, for example, and then between the annular step portion 12d of the peripheral wall portion 12a of the liquid reservoir bulging portion 12 and the annular step portion 16b of the annular wall portion 16. The outer peripheral surface and the annular wall portion of the peripheral wall portion 12a of the liquid reservoir bulging portion 12 are contracted by being heated from the state in which the reduced diameter region is covered from the outside and continuously mounted in an annular shape. It can be attached to the outer peripheral surface of 16 in a state of being firmly adhered to it.

As shown in FIG. 1, on the film 18 with a shrink label for decoration, for example, the decoration area 18b is preferably decorated with various decorations for advertising or advertising, and various decorations for improving the aesthetic appearance. In addition, for example, explanations of the content liquid, Noh books, and caution labels such as "Don't drink" can be easily given as appropriate. Further, since the transparent region 18a that allows the inside to be visually recognized is provided, when the content liquid is measured, the amount of the content liquid to be measured in the liquid reservoir 12 is visually recognized through the transparent region 18a. , It is easy to check. Further, preferably, by providing the measuring scale 18c in the transparent region 18a of the film 18 with the shrink label for decoration, the liquid amount of the content liquid can be confirmed more accurately. The weighing scale 18c can be easily provided in the transparent region 18a of the film 18 by, for example, drawing a calibration curve or drawing a numerical value. The measurement scale 18c may be based only on a calibration curve or a numerical value, or may be a combination of these.

As a result, according to the measuring cap 10 of the present embodiment, the film is preferably made visible from the transparent region 18a of the film 18 by the shrink label for decoration so that the amount of the content liquid can be confirmed. Through 18, it becomes possible to easily apply decoration, and it becomes possible to improve the design and the advertising property.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the weighing scale can be provided on the peripheral wall portion of the liquid reservoir portion of the portion corresponding to the transparent region of the film, and while visually recognizing the weighing scale provided on the peripheral wall portion through the transparent region of the film, the weighing scale can be provided. The amount of the content liquid may be confirmed accurately. The measurement scale can also be provided by engraving a measurement line or a numerical value on the peripheral wall portion 12a of the liquid reservoir bulging portion 12.

Further, the film provided with the transparent region does not necessarily have to be continuously attached to the region extending from the peripheral wall portion to the annular wall portion of the liquid reservoir portion by covering the constricted portion from the outside, as shown in FIG. 3, for example. In addition, the film can be attached from the peripheral wall portion of the liquid sump bulge portion to the area extending to the bottom portion or the annular shoulder portion without covering the constricted portion from the outside. The liquid reservoir does not necessarily have to be formed by blow molding, for example, as shown in FIG. 4, it is transparent on the peripheral wall of the liquid reservoir which is preferably formed by injection molding and does not bulge in the radial direction. A film having a region can also be attached to form the weighing cap of the present invention. The measuring cap of the present invention has an annular rib extending radially outward from the base end portion of the tubular portion and extending in the circumferential direction of the dispensing cylinder portion, and a liquid reservoir portion from the outer peripheral edge portion of the annular rib portion. Does not necessarily have an annular wall portion that extends in the opposite direction along the axial direction and has an inner peripheral surface formed with an engaging portion with another member. As shown in FIG. 5, for example, the measuring cap of the present invention may be a so-called internal fitting type cap that is detachably and directly attached to the mouth of the container body without using the body cap. A film having a transparent region may be attached to cover the peripheral wall portion of the liquid reservoir portion.
