As shown in FIG. 1, the measuring container portion 32 has an apical cylindrical shape which is slightly reduced in diameter toward the upper side, and the peripheral wall 32a is formed as shown in FIG. 1, FIG. 2 (a), (b), etc. As shown in the drawing, a plurality of concave ribs 33 which are arranged in the vertical direction and extend in the circumferential direction are formed. In the present embodiment, the concave rib 33 functions as a scale, and the user pours the content liquid in the accommodation space S into the measuring container portion 32 to a height that matches the height position of any concave rib 33, The content liquid can be accurately measured. As shown in FIG. 1, the concave rib 33 has a structure in which the outer peripheral surface of the peripheral wall 32a is recessed and the inner peripheral surface protrudes, so that the visibility is high and the user easily recognizes the position of the scale be able to. In the present embodiment, as described later, since the peripheral wall 32a is formed by extrusion blow molding, it is possible to easily form the concave rib 33 having a depth larger than the thickness of the peripheral wall 32a as shown in FIG. it can. In addition, as shown in FIG.2 (b), you may provide the character 34 corresponding to measurement volume by decoration, such as printing, in the vicinity of each concave rib 33. As shown in FIG. In addition, the characters 34 may be formed by fine unevenness provided on the inner surface of the mold at the time of blow molding.

  As shown in FIGS. 2 (a) and 2 (b) and FIGS. 3 (a) and 3 (b), the peripheral wall 32a of the measuring container portion 32 is a visible region 32s in which the contents contained in the inside can be viewed It has a low transmission region 32h in which the light transmittance of visible light is lower than that of the region 32s. In the present embodiment, the visible region 32s is made of only the transparent resin layer and has a high light transmittance to visible light. As a material used for the visible region 32s, for example, low density polyethylene (LDPE) or high density polyethylene resin (HDPE) can be used. In the example of FIG. 3A, the low transmission region 32h includes an inner layer 32h0 made of the same resin as the visible region 32s, a first outer layer 32h1 constituting the outermost layer, and a first outer layer 32h1 and an inner layer 32h0. And a second outer layer 32h2 formed therebetween. In the illustrated example, the visible area 32s and the low transmission area 32h are divided by the circumferential position. The region of the intermittent portion 33a in which the concave rib 33 is not formed is generally configured by a visible region 32s, and the other region is a low transmission region 32h. The outer peripheral surface of the first outer layer 32h1 of the low transmission region 32h is configured to be aligned with the outer peripheral surface of the visible region 32s. That is, the visible region 32s and the low transmission region 32h are configured to have the same thickness. However, the present invention is not limited to this aspect, and the thickness of both may be different.

  As shown in FIG. 3B, the first outer layer 32h1 and the second outer layer 32h2 are configured such that the ratio of the thickness of the first outer layer 32h1 to the thickness of the second outer layer 32h2 differ depending on the height position. That is, the thickness of the first outer layer 32h1 is configured to be thicker than the thickness of the second outer layer 32h2 on the side closer to the bottom wall 32b (lower end in FIG. 3B) of the peripheral wall 32a. The thickness of the first outer layer 32h1 decreases in the direction of the dispensing cylinder 35 and the thickness of the second outer layer 32h2 increases. In addition, the first outer layer 32h1 and the second outer layer 32h2 are colored in different colors, respectively, as a low transmitting material for making the light transmittance of visible light in the low transmitting region 32h lower than the light transmittance of the visible region 32s. It is configured. As described above, the low transmission region 32 h of the peripheral wall 32 a is observed as different colors because the thickness ratio of the first outer layer 32 h 1 and the second outer layer 32 h 2 differs in the upper and lower portions. Therefore, the color of the peripheral wall 32 a of the measuring container portion 32 can be made to be gradation changing in the vertical direction.

  The direction in which the color changes is not limited to the vertical direction. For example, by configuring the thickness of the first outer layer 32 h 1 and the second outer layer 32 h 2 depending on the circumferential position, the peripheral wall 32 a Can be a gradation that changes in the circumferential direction.

  Further, in the present embodiment, the outer layer includes the first outer layer 32h1 and the second outer layer 32h2 so that the thicknesses of the both change in a complementary manner. However, the present invention is not limited to this aspect. The outer layer of the structure may be configured to change in thickness in a predetermined direction. In addition, the thickness of the outer layer (whether a single layer structure or a multilayer structure) does not have to be changed. When the thickness of the outer layer is not changed, the color of the low transmission region 32 h does not change.

  Further, in the present embodiment, the color change in the low transmission region 32h is configured to be gradation, but the present invention is not limited to this aspect, and for example, the color is changed to a marble shape (marble pattern) It is also good.

  As materials used for the first outer layer 32h1 and the second outer layer 32h2, for example, a material obtained by adding a coloring agent to low density polyethylene (LDPE) or high density polyethylene resin (HDPE) to reduce the light transmittance to visible light Can be used.

  In the present embodiment, low density polyethylene (LDPE) or high density polyethylene resin (HDPE) or the like having only a transparent resin layer and having a high light transmittance to visible light is used as a material constituting the visible region 32s. Although comprised, it is not limited to this aspect. The material constituting the visible region 32s may be a colored transparent material, a semitransparent material, or the like as long as the content liquid contained in the inside of the measuring container portion 32 can be visually recognized, and necessarily has a high light transmittance for visible light. It is not necessary to have the material. In addition, the low transmission region 32h only needs to be able to enhance the decorativeness by configuring the light transmittance for visible light to be lower than that of the visible region 32s. In addition, that the light transmittance with respect to visible light is lower than the visible region 32s here includes an opaque state in which the inside can not be substantially recognized. The low transmission material (the first outer layer 32h1 and the second outer layer 32h2) used in the present embodiment may be any material that can lower the light transmittance of the low transmission region 32h to visible light as compared to the visible region 32s. It is not necessary to make the light transmittance of the light emitting diode lower than that of the visible region 32s resin material. From the viewpoint of the visibility of the content liquid, the higher the light transmittance to visible light of the visible region 32s, the better, and from the viewpoint of decoration, the light transmittance to the visible light of the low transmittance region 32h is preferably low. There are many.

  The dispensing cylinder 35 has a cylindrical shape which descends downward from the inner peripheral end of the upper wall 31 e. As shown in FIG. 1, a pouring portion 35 a is formed on the pouring barrel 35 by further extending downward in one circumferential direction. That is, the pouring portion 35 a constitutes the lower end portion of the pouring barrel 35. In addition, the pouring part 35a is not limited to the aspect which has the level | step-difference part which protrudes downward as shown in FIG. 1, For example, the shape which length changes gently like the nozzle 28 is also included, and various kinds It is a concept that includes a pouring section of a shape. After the user finishes measuring the content liquid, when the measuring cap 30 is tilted so that the pouring portion 35a is located on the lower side, the content liquid in the measuring container portion 32 is poured out through the pouring portion 35a. Can be poured out more precisely to the desired location.

  In this embodiment, as shown in FIGS. 2A and 2B, the intermittent portion 33a in which the concave rib 33 is not formed is provided at the circumferential position where the pouring portion 35a is formed. As a result, when the metering cap 30 is tilted so that the pouring portion 35a is positioned on the lower side as described above and the content liquid is poured out, the content liquid does not pass through the concave rib 33 portion of the peripheral wall 32a as much as possible. Therefore, the content liquid does not remain on the inner peripheral surface side of the concave rib 33, and the flow of the content liquid is not disturbed by the unevenness of the concave rib 33 portion. Moreover, it is preferable to provide the said character 34 in the intermittent part 33a.

  As shown in FIG. 1, when the cap body 31 of the measuring cap 30 is attached to the mounting cap 21, the nozzle 28 is covered by the measuring container 32 and the nozzle cap 20 is closed. On the other hand, when the cap body portion 31 is removed from the mounting cap portion 21, the nozzle 28 is exposed and the content liquid can be poured out.

  When the measuring cap 30 is attached to the nozzle cap 20 shown in FIG. 1 and the measuring container portion 32 is gripped and turned in the circumferential direction to release the screw connection between the attaching cylinder 31a and the outer peripheral wall 23, the nozzle cap 20 is removed. In contrast, the measuring cap 30 moves upward. Then, by pulling out the measuring cap 30 in a state where the screw engagement is completely released, the dispensing cylinder 35 disposed between the side wall 27 a of the partition wall 27 and the nozzle 28 is moved upward and the nozzle It can be removed from the cap 20.

  With the measuring cap 30 removed from the nozzle cap 20 and the nozzle 28 exposed, the container body 10 is housed in an inclined posture in which the slit 28 a is upward from an upright posture in which the tip of the nozzle 28 faces upward. The liquid content in the space S can be poured out from the tip of the nozzle 28 through the nozzle hole 27 c. At this time, since the partition wall 27 is provided inside the mouth portion 13 and the nozzle 28 is configured to rise from the inner peripheral edge of the partition wall 27, the liquid in the storage space S of the container main body 10 is formed in a bowl shape. It is guided along the nozzle 28 and poured out from the tip of the nozzle 28. The user once pours into the measuring cap 30 placed in the posture shown in FIGS. 2A and 2B and measures only a predetermined amount, and then pours out from the pouring portion 35a to the target location as described above. Alternatively, the liquid content from the nozzle 28 may be poured directly to the desired location.

  After the content liquid is poured out, even if the content liquid attached to the tip of the nozzle 28 drops down along the outer peripheral surface of the nozzle 28 when the container main body 10 is returned to the upright posture, the content liquid is It does not hang down to the outside of 13 and hangs down along the nozzle 28 to be received by the upper surface of the partition 27 and returned from the portion of the slit 28 a of the nozzle 28 to the receiving space S of the container body 10. Therefore, according to the measuring container 1, it is possible to prevent dripping of the content liquid to the outside while pouring out the content liquid from the nozzle 28.

  The measuring cap 30 removed from the nozzle cap 20 has the dispensing cylinder 35 on the lower side and the measuring container portion 32 on the upper side, and the dispensing cylinder 35 is inserted into the space between the side wall 27a and the nozzle 28. The nozzle 28 can be closed by attaching the measuring cap 30 to the nozzle cap 20 again.

  Next, a method of manufacturing the measuring cap 30 according to the present embodiment will be described.

  In manufacturing the measuring cap 30 according to the present embodiment, first, the light transmittance of the inner layer, which is made of transparent resin and constitutes the visible region 32s, and the low transmittance region 32h is lower than the light transmittance of the visible region 32s. Generating a parison with the outer layer. In the present embodiment, the outer layer has the first outer layer 32h1 and the second outer layer 32h2 colored differently, and is blown so that the ratio of the thickness of the second outer layer 32h2 to the first outer layer 32h1 gradually increases. It is supplied to a molding die. Next, the above-described parison supplied to the blow molding die is extrusion blow molded to form the measuring container portion 32. As a result, a measuring container portion 32 having a visible region 32s and a low transmission region 32h as shown in FIG. 3A is formed. Further, since the ratio of the thickness of the second outer layer 32h2 to the first outer layer 32h1 of the parison supplied to the blow molding die is controlled to gradually increase, each layer configuration in the low transmission region 32h of the peripheral wall 32a is As shown in FIG. 3B, the ratio of the thickness of the second outer layer 32h2 to the first outer layer 32h1 gradually increases from the bottom wall 32b toward the dispensing cylinder 35. Thus, the color of the low transmission area 32 h of the peripheral wall 32 a can be configured to be gradation.

  As described above, in the present embodiment, the peripheral region 32a of the measuring container portion 32 has a visible region 32s in which the content liquid contained in the inside can be visually recognized, and a low light transmittance of visible light than the visible region 32s. The low transmission region 32 h is configured to have a multilayer structure including the material of the visible region 32 s and one or more layers of low transmission materials. By this, in addition to the fact that the content liquid inside the measuring container portion 32 can be visually recognized and measured through the visible region 32s, it is possible to secure the decorativeness by the low transmission region 32h.

  Moreover, in the present embodiment, the measuring container portion 32 is configured to be formed separately from the cap main body portion 31 and the dispensing cylinder 35. As a result, the measuring container portion 32 having the visible region 32s and the low permeation region 32h can be easily formed by extrusion blow molding. In addition, the shaping | molding method of the measurement container part 32 is not limited to extrusion blow molding, Various other shaping | molding methods are employable.

  Further, in the present embodiment, the visible region 32s and the low transmission region 32h are configured to be divided by the circumferential position. Thus, the measurement container portion 32 can be easily formed by extrusion blow molding a parison having the visible region 32s and the low permeation region 32h.

  The low transmission region 32 h may be formed of a single-layer resin layer not including the material of the visible region 32 s.

  Further, in the present embodiment, in the low transmission region 32h, the thickness of the low transmission material is configured to change in the predetermined direction. In particular, the low transmission region 32 h includes a plurality of low transmission materials such that the thickness of one low transmission material decreases and the thickness of the other low transmission materials increases in a predetermined direction. By configuring in this way, it is possible to make the change in color in the low transmission area 32 h of the measuring container part 32 be gradation.

  Further, in the present embodiment, since the measuring container portion 32 is formed by extrusion blow molding of a parison, the measuring container portion 32 can be formed without using a mold or the like having a complicated structure.

  Further, in the present embodiment, the extrusion blow molding parison is configured such that the low transmission region 32 h having a lower light transmittance of visible light than the visible region 32 s is intermittently formed in the circumferential direction. This makes it possible to relatively easily form the measuring container portion 32 in which the visible region 32s and the low transmission region 32h are divided at circumferential positions by extrusion blow molding.

It has a low transmission area 72h with low light transmission. In the present embodiment, the visible region 72s is made of only the transparent resin layer and has high light transmittance to visible light. As a material used for the visible region 72s, for example, low density polyethylene (LDPE) can be used. On the other hand, in the low transmission region 72h, in the example shown in FIG. 5, the light transmittance of visible light in the low transmission region 72h is different from the light transmittance of the visible region 72s. Also has an outer layer 72h1 for lowering. In the illustrated example, the visible area 72s and the low transmission area 72h are divided by the circumferential position, and as shown in FIGS. 4 (a), (b) and FIG. Transmission regions 72h are alternately provided at equal intervals in the circumferential direction. The outer peripheral surface of the outer layer 72h1 of the low transmission area 72h is configured to be aligned with the outer peripheral surface of the visible area 72s. That is, although the visible area 72s and the low transmission area 72h are configured to have the same thickness, the present invention is not limited to this aspect, and the thicknesses of both may be different.

  In addition, as a material used for outer layer 72h1, the material which added the coloring agent to high density polyethylene resin (HDPE) etc., for example, and reduced the light transmittance to visible light can be used, for example.

  As described above, in the present embodiment, high-density polyethylene resin (HDPE) in which a low-density polyethylene (LDPE) which is a transparent and soft material is used for the visible region 72s and a coloring agent is added to the outer layer 72h1 of the low-transmission region 72h In addition to the fact that the content liquid inside the measuring container 72 can be visually recognized and measured through the visible region 72s, the low transmission region 72h can be decorated by coloring or the like. In addition, when removing the measuring cap 70 by gripping the peripheral wall 72a of the measuring container portion 72, the low density polyethylene (LDPE) of the visible region 72s which is a soft material and has a small coefficient of longitudinal elastic modulus is bent to improve grip. it can. The low elastic region 72h may be configured to have a smaller modulus of longitudinal elasticity than the visible region 72s.

  The measuring container portion 72 used for the measuring cap 70 of the present embodiment can be formed by extrusion blow molding a parison having an inner layer and an outer layer. For example, the visible region 72s and the inner layer 72h0 in FIG. After molding in a mold, the outer layer 72h1 can be formed by so-called two-material molding in which the outer layer 72h1 is molded in a mold on the secondary side. Alternatively, the visible region 72s and the inner layer 72h0 in FIG. 5 can be formed by insert molding as an insert material. In the case of insert molding, the outer layer 72h1 may be used as an insert material. Furthermore, the measurement container portion 72 may be formed by biaxial stretch blow molding a preform formed by two-material molding or insert molding. In this case, the cap body 71 and the dispensing cylinder 75 can be integrally provided.

  As described above, in the present embodiment, the visible region 72s and the low transmission region 72h are configured to have different longitudinal elastic coefficients. By this, when gripping the peripheral wall 72a of the measuring container part 72 and removing the measuring cap 70, the area made of a soft material and having a smaller coefficient of longitudinal elastic modulus can be bent to improve the grip property.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various changes and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions included in each component can be rearranged so as not to be logically contradictory, and a plurality of components can be combined or divided into one. It should be understood that these are also included in the scope of the present invention.
