Description

  The present invention relates to a pressure discharge container in which a single press discharge amount is different along a circumferential direction of a container body.

  Conventionally, in a pressure discharge container that presses the container body from the outside and discharges the content liquid, the container body has a plate piece that locks the pressure inside the container body, and the inner surface of the container body comes into contact with the plate piece when pressed. There is known a quantitative discharge container in which the pressure is locked and the content liquid is always discharged in a fixed amount.

  Also, a cylindrical body having a different diameter in the axial direction is provided inside the container main body, or a plurality of concave portions having different depths are formed in the upper and lower directions on the outer wall of the container main body to change the pressed portion, or a concave portion to be pressed. An invention is known in which the amount of content liquid ejected by changing the amount is changed.

JP 2001-151283 A

  However, the distance between the inner surface of the container main body and the plate for pressing and locking is constant, and the amount of content liquid discharged by one press is determined. Accordingly, even when it is desired to increase or decrease the discharge amount, the discharge amount of the content liquid cannot be changed.

  In addition, in the case of a pressurized discharge container that changes the discharge amount by changing the pressing location in the axial direction, the holding position of the container moves up and down in the axial direction when the discharge amount is changed, and from the holding position to the discharge port of the container each time. There was a problem that it was difficult to balance when holding the container by changing the distance.

  An object of the present invention is to provide a pressure discharge container in which the discharge amount in one press can be selected and the height of the holding position does not change even when the discharge amount is changed.

  In order to solve the above-mentioned object, the present invention is configured as a pressure discharge container as follows.

  1. In a press discharge container that includes a press locking member that locks the pressure deformation of the container main body in the pressure deformable container main body, and presses the container main body from the outside to the press locking member to discharge the content liquid. A plurality of pressing locations that are pressed in the diameter direction are provided on the same circumference of the container body, and the lateral width of the pressing locking member measured along these pressing locations is made different for each pressing location.

  Specifically, by changing the width of the press locking member, when the pressure discharge container is pressed from the outside, the pressure until the inner surface of the pressure discharge container is locked in contact with the outer surface of the press lock member The amount is configured to be different for each pressed location.

  Since the pressure discharge container is sandwiched and pressed from both sides by hand, the amount of pressing is the sum of the amounts of movement on both sides. The press locking member is preferably formed symmetrically with respect to the center of the container main body, but is not necessarily symmetrical. For example, the pressing engagement member on the side where the thumb hits may be brought closer to the inner surface of the container body, and the amount of pressing with which the container body is pressed with the thumb may be reduced.

  2 and 1, the press locking member has a shape in which a plurality of locking plates having different widths are arranged radially. The locking plate is basically parallel to the axial direction of the container body.

  3 and 1, the press locking member is a polygonal cylindrical body having different intervals between two sides facing each other along the pressing direction. The polygonal cylindrical body may be a rectangular cylindrical body having an odd number of corners such as a triangular cylindrical body, but is preferably a rectangular cylindrical body having an even number of corners since one of the hands hits the corner of the rectangular cylindrical body when pressed.

  4 and 1, the press locking member is an elliptical cylinder. The elliptic cylinder is provided symmetrically with respect to the center of the container body, but it may be attached with one side closer to the inner surface of the press-discharge container and shifted from symmetry. Further, the pressing locking member is not an exact oval shape, and may be, for example, an oval cylinder or an egg-shaped cylinder.

  In the pressure discharge container according to any one of 5, 1 to 4, the press locking member is attached to the inner surface of the lid body assembled to the container main body. The press locking member attached to the inner surface of the lid body can be inserted from the mouth portion of the container body, and is arranged inside the container body by tightening the lid body to the mouth portion.

  In the press discharge container according to any one of 6, 1 to 4, a mark indicating a position to be pressed on the outer wall of the container main body is provided corresponding to each different lateral width of the press locking member. For example, a mark corresponding to the discharge amount is provided corresponding to the lateral width of the press locking member. The mark may be provided on the container body by printing or may be provided by molding.

  Since the distance from the inner surface of the container main body to the press locking member of the press discharge container of the present invention is different along the circumferential direction of the container main body, by changing the place to be pressed in the circumferential direction, the single press The discharge amount can be appropriately selected.

  And even if the discharge amount is changed, the holding position with the container body only changes in the circumferential direction, and there is no change in the distance to the discharge port of the press discharge container, so there is no big fluctuation in the balance when holding the container, The content liquid can be discharged from the container constantly and stably.

  In addition, the press locking member can be easily formed of resin, and the press discharge member capable of changing the discharge amount can be manufactured at low cost by simply assembling the press locking member in the container body.

  FIG. 5 shows the overall shape of the pressure discharge container 2. The pressure discharge container 2 includes a container body 4 having a mouth part at the top, a lid 6 attached to the mouth part 5 of the container body 4, a press locking member 8 provided inside the container body 4, a mouth It is formed from the stopper 20.

  As shown in FIG. 1, the container body 4 is a bottomed cylindrical body having a mouth portion 5 at the top, and is a resin container having a squeeze property that is easily deformed and restored by pressing from the outside. A screw portion 22 is formed on the outer periphery of the mouth portion 5, and the lid body 6 is screwed into the screw portion 22. On the outer wall of the container body 4, many, medium and small marks 3 are horizontally marked at the same height.

  The lid body 6 is a cylindrical body with a top, and a tapered mouth cylindrical body 10 extending upward is formed at the center of the top wall 11. The inside of the mouth cylindrical body 10 penetrates the top wall 11 and is a lid body. 6 communicates with the inside. The plug 20 is detachably fitted to the discharge port 13 (see FIG. 5) of the mouth tube 10.

  As shown in FIG. 2, the press locking member 8 has a shape in which three locking plates 9 having different widths are crossed at the central portion, and is integrally formed of resin and arranged radially. The plate 9 is fixed integrally at the central portion. The press locking member 8 is screwed and fixed to the inner surface of the lid body 6, that is, the lower surface of the top wall 11, and is inserted into the container body 4 through the mouth portion 5 and screwed to the mouth portion 5. The container body 4 is disposed coaxially with the container body 4. Note that the fixing of the press locking member 8 to the top wall 11 is not limited to screwing, and any method such as adhesion or fitting may be used.

  Furthermore, the press locking member 8 may be formed by combining the individual locking plates 9 in a radial manner instead of being formed by integral molding.

  When the press locking member 8 is disposed inside the container main body 4, the locking plate 9 extends radially from the center of the container main body 4, and the horizontal width of each locking plate 9 is different. 2 are different from A, B, and C as shown in FIG. 2 along the same circumference.

  Corresponding to each of these distances A, B, and C, three marks 3 indicating the pressed positions of “many”, “medium”, and “small” are marked on the outer wall of the container body 4 respectively.

  Further, each of the locking plates 9 pushes the pressed portion in a state where the pressing locking member 8 is inserted into the container main body 4, and even if any of the locking plates 9 is clamped, the locking plate 9 is pressed to such an extent that the liquid content is discharged. It has strength that does not easily deform under pressure. In addition, notches are formed in the vicinity of the attachment of the locking plates 9 to the lid body 6 so as not to block the discharge ports 13.

  The press locking member 8 may be attached to the inner surface of the mouth portion 5 of the container body 4 instead of the inner surface of the lid body 6.

  Next, use of the press discharge container 2 will be described.

  The press locking member 8 is inserted into the container body 4 containing the content liquid from the mouth portion 5, and the lid body 6 is fastened to the mouth portion 5. When discharging the content liquid, the stopper 20 is removed, the discharge port 13 is directed downward, one of the marks 3 is selected, and the container body 4 is pressed from the outside while pressing the position of the selected mark 3.

  For example, when it is desired to discharge a large amount of the content liquid, a finger is applied to the position of the “many” mark 3 and the container body 4 is pressed until it contacts the pressing locking member 8 between the opposite side. Then, the hand holds the locking plate 9 having the narrowest width of the pressing locking member 8, so that the pressing amount for pressing the container body 4 is the largest as A (exactly twice A), and the maximum discharge amount is can get.

  Similarly, when the “medium” mark 3 is selected and the container body 4 is pressed until it comes into contact with the pressing locking member 8, the pressing amount becomes B, and a medium discharge amount corresponding to the pressing amount is obtained. Furthermore, when the “small” mark 3 is selected and pressed, the pressing amount of the container body 4 becomes C and the pressing amount becomes the smallest, and the minimum amount of content liquid is discharged from the discharge port 13.

  As described above, the press discharge container 2 is provided with the press locking member 8 composed of a plurality of locking plates 9 having different lateral widths inside the container body 4, so that the mark 3 provided on the circumference of the same height is provided. By selecting and pressing the container body 4 from both sides, a desired amount of content liquid can be discharged from the discharge port 13.

  Since the pressure discharge container 2 can change the discharge amount by one press by changing the pressing position along the same circumference, the holding position with the container body 4 is not changed, and the same pressure discharge container 2 is used. Therefore, the balance can be easily maintained and the discharge operation can be easily performed.

  On the other hand, since the pressing amount is the same for the same mark 3, a predetermined amount of content liquid corresponding to the pressed portion can be always discharged by pressing the same mark 3 as a guide.

  Next, another example of the press locking member 8 is shown in FIG. 3 has a deformed hexagonal cylindrical shape, and the distances from two sides facing each other across the center of the container body 4 to the inner surface of the container body 4 are different from A, B, and C, respectively. Thus, even if the pressing locking member 8 is formed in a hexagonal cylindrical shape, the pressing amount along the circumference of the same height of the container body 4 can be changed to A, B, C, and the mark 3 is used as a guide. A desired amount of the content liquid can be discharged by selecting the pressed portion.

  The press locking member 8 is fixed to the lid 3 in the same manner as described above, and an opening (not shown) is appropriately formed on the wall surface of the hexagonal cylinder so that the content liquid flows into the press locking member 8. is there. In the present invention, the press locking member 8 is not limited to the hexagonal cylinder.

  FIG. 4 shows a press locking member 8 formed in an elliptic cylinder shape. Thus, even in the press locking member 8 formed in the shape of an elliptic cylinder, the distance from the press locking member 8 to the inner surface of the container body 4 along the circumference of the same height of the press discharge container 2 is A, B. , C, the mark 3 marked at the position corresponding to the distances A, B, and C is selected, and the container body 4 is pressed until it abuts against the pressing locking member 8, so that the respective pressing locations The desired amount of content liquid corresponding to the mark 3 can be discharged by changing the pressing amount at.

  In each of the above examples, the press locking member 8 is provided symmetrically with respect to the center of the container main body 4 inside the container main body 4, but the present invention is not limited to this and is shifted to one side. It may be formed. Moreover, the number of the marks 3 is not limited to three, and the number of pressing points may be increased or decreased.
