  However, a squeeze container that discharges a different amount of content liquid depending on the pressing position of the container body usually uses a pressure regulating member such as a regulating cylinder separately from the container body in order to obtain meterability. , Manufacturing costs are high.

  Further, in order to discharge a predetermined amount of content liquid by the pressing position of the container main body, it is necessary to confirm the position in each of the two directions to be pressed with the container main body interposed therebetween. For example, in the container described in Patent Document 2, in order to discharge the content liquid so that the discharge amount becomes “many”, when grasping the container main body with one hand, the thumb is placed on the “many” mark, and the rest Must be placed in the vertical direction at the opposite side of the “many” mark.

  In this case, if the container is cylindrical, or if the container or hand is wet, the position pressed by the thumb and the remaining fingers is the original mark and the opposite position. May deviate from.

  On the other hand, the present invention is a squeeze container that can be manufactured by integral molding without requiring a separate pressure regulating member from the container body, and discharges the inner solution according to the pressed position of the container body. An object of the present invention is to provide a squeeze container that can be varied in quantity and has good meterability.

  In order to achieve the above-mentioned object, the present invention is a squeeze container by integral molding, and the peripheral wall of the container body has a front part in which weighing scales are arranged in the vertical direction, and a back part facing the front part, The back surface portion has a plurality of concave and convex areas extending in the vertical direction or convex and concave regions formed in a corrugated shape, and the maximum distance between the front surface portion and the back surface portion in the cross section of the container body is To provide a squeeze container that varies depending on the height of the direction.

  According to the squeeze container of the present invention, the back surface portion of the peripheral wall of the container body is difficult to bend by having a plurality of concave and convex portions or convex portions extending in the vertical direction, and the front portion is bent. Cheap. Therefore, when the thumb is placed on the front part, the remaining fingers are put on the uneven area on the back part, and the container body is pressed to discharge a predetermined amount of the content liquid, the position of the thumb is determined according to the attachment position of the measurement scale. All that is required is the rest of the fingers, so there is no need to confirm their position. Therefore, it is possible to easily perform a squeeze operation for discharging a predetermined amount of content liquid.

  Furthermore, the squeeze container of the present invention can be obtained at a low cost because the pressure regulating member separate from the container body is omitted.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol represents the same or equivalent component.

  FIG. 1 is a (a) front side perspective view, (b) side side perspective view, (c) back side perspective view, and (d) a transverse sectional view of a squeeze container 1A according to an embodiment of the present invention.

  The squeeze container 1 </ b> A includes a container main body 10 that stores the content liquid, and a nozzle cap 20 that is detachably attached to the discharge nozzle 12 of the container main body 10.

  The container main body 10 is integrally molded by blow molding using a plastic material, and the peripheral wall has a front portion 14 whose cross section protrudes in an arc shape and a substantially linear back portion 15. Here, as the plastic material, for example, thermoplastic resins such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polyvinyl chloride (PVC) are preferable. In addition, as a plastic material which forms the container main body 10, what has transparency or translucency so that the liquid level of a content liquid can be visually recognized from the outer side of the container main body 10 is preferable.

  Moreover, as the capacity | capacitance of the container main body 10, 1000 mL or less is preferable and 500 mL or less is more preferable from the point which lifts the squeeze container 1A with one hand and enables squeeze operation.

  The front part 14 has flexibility, and the measurement scale 11 arranged in the up-down direction is attached to the surface. Each weighing scale 11 protrudes linearly, and the discharge amount (for example, 10 mL, 20 mL, 30 mL) of the content liquid when the weighing scale 11 is pressed as shown by the arrow in FIG. It is attached at intervals.

  In addition, about the attachment method of a measurement scale, it should just be attached in the state which can be identified at the time of measurement, for example, you may form together at the time of shaping | molding of a container, and you may give by printing etc. after a container shaping | molding. In the former case, in addition to projecting in the above-described line shape, a scale may be added by a concave portion.

  Moreover, the discharge amount per squeeze is appropriately set according to the use and properties of the content liquid.

  As shown in FIGS. 1C and 1D, the entire surface of the back surface portion 15 is an uneven region in which a plurality of concave portions extending in the vertical direction are formed in a corrugated plate shape. More specifically, a plurality of rectangular grooves 16 extending continuously in the vertical direction are juxtaposed in a corrugated shape. Therefore, the back surface portion 15 is extremely difficult to bend compared to the front surface portion 14, and is particularly difficult to bend in the horizontal direction. Even if the front surface portion 14 and the back surface portion 15 are sandwiched and pressed with a finger, the back surface portion 15 is substantially Does not deform. The pitch and height of the grooves 16 depend on the type and thickness of the plastic material used, but the groove depth L2 is 1 mm or more, the groove width L3 is 1 mm or more, and the pitch L4 is 2 mm or more. preferable.

  Further, in the present invention, the concave or convex portion of the back surface portion 15 extends in the vertical direction is not limited to the case where the concave portion or convex portion strictly extends in the vertical direction (that is, the standing direction) of the container body 10, As long as the back surface portion 15 is not easily bent in the horizontal direction, the back surface portion 15 may extend in an obliquely vertical direction.

  Furthermore, in the present invention, that the concave portion or the convex portion is formed in a corrugated shape means that the thickness of the sheet is not substantially changed between the concave portion and the convex portion. As a result, the amount of resin in the container can be reduced compared to the case where the thickness of the sheet differs between the concave portion and the convex portion, and since the thickness can be made uniform, the molding ability is improved and deformation during molding can be prevented. There is an advantage. Therefore, the plastic sheet thickness at the bottom of the groove 16 in FIG. 1 and the plastic sheet thickness at the convex portion between the grooves are also substantially the same.

  The overall outer shape of the container main body 10 is a taper shape in which the inner diameter of the upper end portion 10a is narrower than the inner diameter of the lower end portion 10b, and the back surface portion 15 stands substantially vertically from the bottom surface. Therefore, the maximum distance L (FIG. 1 (d)) between the front portion 14 and the rear portion 15 in the cross section of the container body 10 varies depending on the vertical height of the container body, and more specifically, The distance L is smaller as the vertical position is higher.

  In order to discharge the content liquid from the squeeze container 1A with a desired discharge amount, a thumb is placed at a position corresponding to the discharge amount in the arrangement area of the measurement scale 11 of the front portion 14, and the remaining liquid is left on the back surface portion 15 on the opposite side. As shown in FIG. 2, the container body 10 is pressed until the front part 14 and the back part 15 come into contact with each other. Thereby, the internal solution can be discharged from the discharge hole 13 in an amount corresponding to the position of the thumb. In this case, since the back surface portion 15 is hardly deformed, the remaining fingers may be placed at a position where the container body 10 can be easily gripped on the back surface portion 15, and it is not necessary to match the position according to the discharge amount. Further, since the entire rear surface 15 stands up substantially perpendicularly from the bottom surface, the position of the front surface portion 14 opposite to the arrangement area of the weighing scale 11 also has a surface perpendicular to the bottom surface. Easy to apply fingers. Therefore, according to the squeeze container 1A, the content liquid can be discharged from the discharge hole 13 with a desired discharge amount very easily. In addition, since the cross-sectional shape of the front portion 14 protrudes in an arc shape from the back portion 15, it is possible to ensure the resilience of the shape of the container body 10 after discharging the content liquid, and It also has resistance to decompression deformation.

  In the present invention, the uneven region provided on the back surface portion 15 is preferably provided on the entire surface of the back surface portion 15 as shown in FIG. 1C from the viewpoint of strength, manufacturing, and ease of use. It is not necessary to provide the entire surface. When the position of the front portion 14 relative to the arrangement area of the weighing scale 11 is an uneven region perpendicular to the bottom surface, the upper and lower ends and both side edges of the back surface portion 15 may be flat, which will be described later. As shown in FIG. 4, when the central portion is projected to the front portion 14 side, both side edge portions and the upper end portion of the back surface portion 15 are formed as uneven regions, and grooves and ribs may not be formed in the central portion.

  In the present invention, the concave portion or the convex portion forming the concave and convex area of the back surface portion 15 can take various shapes. For example, the cross-sectional shape of the recess may be a continuous V-shaped groove 16b as shown in the cross-sectional view of the container body 10 shown in FIG. 3A, or continuous as shown in the cross-sectional view of the container body 10 shown in FIG. 3B. A typical semi-cylindrical groove 16c may be used. As shown in FIG. 3C, the dimple-like grooves 16d extending in the vertical direction may be intermittently formed, or as shown in FIG. 3D, the square grooves 16e extending in the vertical direction may be intermittently formed. Good. Further, as shown in FIG. 3E, the grooves 16 extending continuously in the diagonally up and down direction may be arranged in a C shape.

  Further, as in the squeeze container 1B shown in FIG. 4, an uneven region in which grooves 16 extending in the vertical direction are arranged in parallel is formed on both side edge portions and upper end portions of the back surface portion 15. Alternatively, a protruding portion 17 that protrudes toward the front portion 14 may be formed. Thereby, since the maximum distance L between the front part 14 and the back part 15 in the cross section of the container main body 10 can be reduced as compared with the squeeze container 1A of FIG. 1, the front part required when the content liquid is projected. 14 can be reduced, and the discharge amount by one press can be reduced.

  The protrusion 17 may not be formed with a plurality of concave and convex areas extending in the vertical direction. By forming concave and convex regions on both side edges and upper end of the back surface 15, when pressing the container body 10 while holding the front surface 14 and the back surface 15 with fingers, Since it can apply, the deformation | transformation of the back surface part 15 can be prevented. Therefore, also in this squeeze container 1B, it is not necessary to confirm the position of the finger applied to the back surface portion 15 when discharging a predetermined amount of content liquid.

  In the squeeze container of the present invention, the shape of the discharge nozzle 12 and the nozzle cap 20 is not limited, and an applicator such as a brush or a brush may be provided depending on the application.

  Moreover, as a shaping | molding method of the container main body 10, injection blow molding etc. other than blow molding can also be used. From the viewpoint of the shape of the container body and the manufacturing cost, blow molding is preferred.

  The squeeze container of the present invention is useful as a discharge container for laundry detergent, softener, bleach, automatic dishwashing detergent and the like.
