  Hereinafter, the squeeze discharge container 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the present specification, the vertical direction means a direction along the central axis O of the mouth 2a of the outer container 2. Further, the upper direction means the direction from the bottom 2c to the mouth 2a, and the lower means the opposite direction. Further, the vertical cross section means a cross section including the central axis O of the mouth portion 2a, and the horizontal cross section means a cross section perpendicular to the central axis O of the mouth portion 2a.

  As shown in FIG. 1, the squeeze discharge container 1 according to this embodiment includes an outer container 2, an inner container 3, a cap 4, and a set of regulating members 5.

  The outer container 2 includes a substantially cylindrical mouth portion 2a centering on the central axis O, a body portion 2b that is connected to the mouth portion 2a and can be deformed inward by squeeze, and a bottom portion 2c that closes the lower end of the body portion 2b. ,have. The mouth portion 2a has a two-stage cylindrical shape with the lower portion expanded in diameter. A male screw portion 6 for attaching the cap 4 is provided on the outer peripheral surface of the upper portion of the mouth portion 2a. However, in place of the attachment by the male screw portion 6, a configuration that enables the attachment by the concave-convex shape may be adopted. A vent hole 7 that penetrates the mouth portion 2a in the radial direction is provided in an upper portion of the mouth portion 2a. In this embodiment, two vent holes 7 are provided, but the number can be increased or decreased as appropriate. A neck ring 8 is provided on the outer peripheral surface of the lower portion of the mouth portion 2a. However, the neck ring 8 may not be provided. The body 2b has an elliptical cross section across the entire vertical direction. In addition, the upper portion of the trunk portion 2b gradually increases in diameter from the lower end of the mouth portion 2a downward, and the middle portion in the vertical direction of the trunk portion 2b has no change in diameter in the vertical direction, and the lower portion of the trunk portion 2b. Are gradually reduced in diameter toward the lower side.

  The inner container 3 is disposed inside the outer container 2 and partitions the accommodation space S for the contents C.

  In the present embodiment, the outer container 2 is configured by an outer layer body of a delamination container (also referred to as a delamination container), and the inner container 3 is configured by an inner layer body of the delamination container. Such a lamination peeling container can be formed by extrusion blow molding (EBM: Extrusion Blow Molding), for example. In this case, first, a synthetic resin material for the outer layer body having low compatibility and a synthetic resin material for the inner layer body are coextruded to form a laminated parison, and this laminated parison is blow-molded using a mold. A container having a laminated structure in which the inner layer body is detachably adhered to the inner surface of the outer layer body can be formed. After extrusion blow molding, the vent 7 is formed in the mouth portion 2a, and the inner layer body is once contracted by suction or the like from the upper end opening (opening formed by the upper end edge) of the mouth portion 2a. Can be peeled off from the outer layer body. Next, a set of through-holes 9 can be formed in the body portion 2 b, and the regulating members 5 can be attached to the set of through-holes 9, respectively. Thereafter, the shape of the inner layer body can be restored by, for example, sending air into the inner layer body (accommodating space S). The set of through holes 9 may be formed simultaneously with the formation of the vent holes 7. Further, after forming a set of through-holes 9 without providing the vent holes 7 in the mouth portion 2a, the inner layer body is peeled off from the outer layer body only in the vicinity of the set of through-holes 9 and the contents of the outer container 2 and contents. The vessel 3 may be configured.

  The delamination container may be configured by biaxial stretch blow molding for a bottomed cylindrical preform. In this case, the preform may be a laminated preform including an outer layer that forms the outer layer body and an inner layer that forms the inner layer body. Further, the preform may be a double preform configured by assembling an outer body that forms the outer layer body and an inner body that forms the inner layer body.

  The outer container 2 and the inner container 3 may not be constituted by a delamination container. For example, the outer container 2 and the inner container 3 may be configured by being formed separately and then assembled together.

  A pair of through-holes 9 are provided on the short axis of the elliptical cross section at the middle in the vertical direction of the body 2b. Each set of through-holes 9 is provided with a regulating member 5, and these constitute a set of regulating member 5. In this embodiment, the set of regulating members 5 have the same shape and size. Moreover, the set of through-holes 9 also have the same shape and size in this embodiment. Each of the set of through holes 9 has a circular shape. Each of the set of regulating members 5 includes an extending portion 5a that extends to the inside of the trunk portion 2b through the through-hole 9, and a plate-like portion 5b that is disposed along the outer surface of the trunk portion 2b. Yes. The extending portion 5a is formed in a hollow rod shape having a cylindrical shape. The plate-like part 5 b is formed in a disk shape having a larger diameter than the through-hole 9. The center of the plate-like part 5b is slightly depressed toward the inside of the trunk part 2b, and fits to the belly of the finger when the user squeezes the trunk part 2b. That is, the plate-like part 5b is an operation part for squeezing. Since the plate-like portion 5b is positioned outside the body portion 2b from the through-hole 9, the regulating member 5 is prevented from falling out to the inside of the body portion 2b. Further, an annular engaging convex portion 5c that engages with the inner peripheral surface of the body portion 2b is provided on the outer peripheral surface of the extending portion 5a. Since the engaging convex portion 5c engages with the inner peripheral surface of the body portion 2b, the regulating member 5 is prevented from falling out of the body portion 2b. The through-hole 9 is preferably sealed by the regulating member 5 from the viewpoint of improving the operational feeling during squeezing (preventing pressure loss due to squeezing). However, even if the through-hole 9 is not completely sealed by the regulating member 5, the content is not leaked from the through-hole 9 because the content is accommodated in the inner container 3.

  The cap 4 is attached to the mouth portion 2a and has a discharge port 4a for the contents C. In the present embodiment, the cap 4 includes a base 4b, a lid 4c, a valve body 4d, and a valve pressing member 4e. The lid 4c is connected to the base 4b via a hinge 4f. However, the lid 4c may be configured to be detachable from the base 4b. The base 4b has a mounting cylinder 11 having a female screw portion 10 that is screwed with the male screw portion 6 of the mouth portion 2a. A top wall 12 extending radially inward is connected to the upper end of the mounting cylinder 11, and the top wall 12 is in close contact with the upper end of the mouth portion 2a over the entire circumference. The lower part of the mounting cylinder 11 is in close contact with the outer peripheral surface of the lower part of the mouth part 2a over the entire circumference. Accordingly, the cap 4 blocks the communication between the vent 7 and the outside by being attached to the mouth 2a. By shutting off the communication between the vent 7 and the outside in this way, the operational feeling during squeezing can be improved, and after the contents are discharged, the air from the outside passes between the outer container 2 and the inner container 3 through the vent 7. It is prevented from flowing into.

  The lower surface of the top wall 12 is provided with a two-stepped portion, that is, a lower step portion 12a and an upper step portion 12b, which form an annular shape centering on the central axis O and are continuous in the vertical direction. In addition, a circular opening 12c centered on the central axis O is provided above the upper step portion 12b. The valve body 4d is fixed to the upper step portion 12b by a valve pressing member 4e attached to the lower step portion 12a by fitting. The valve body 4 d is connected to the outer edge portion 13 having an annular shape disposed in the upper step portion 12 b, the frustoconical circumferential wall 14 extending upward from the inner peripheral edge of the outer edge portion 13, and the upper end of the circumferential wall 14. And a partition wall 15 having a downward spherical shape. The peripheral wall 14 and the partition wall 15 are located on the radially inner side of the opening 12 c of the top wall 12. The valve pressing member 4e includes an annular plate 16 having a circular plate shape disposed in the lower step portion 12a, and a frustoconical annular convex portion 17 extending upward from the inner peripheral edge of the annular plate 16. Have. The annular convex part 17 is located radially inward from the outer edge part 13 of the valve body 4d.

  4 d of valve bodies are comprised by the slit valve which has the slit 18 as the discharge outlet 4a. The slit 18 has a cross shape in plan view, but the shape can be changed as appropriate. For example, the slit 18 may have a single character shape or a Y shape in plan view. Further, the valve body 4d is configured to open the discharge port 4a by making the accommodation space S positive, and to open the discharge port 4a also by making the storage space S negative.

  The squeeze discharge container 1 can be used, for example, according to the following procedure. First, the user opens the lid 4c and tilts the outer container 2 as shown in FIG. At this time, the slit 18 of the valve body 4d is closed, and the content C is not discharged from the discharge port 4a.

  Next, as shown in FIG. 3, the user picks up the plate-like part 5 b (operation part) of the pair of regulating members 5 with a finger and squeezes the trunk part 2 b. By this squeeze, the body portion 2b is deformed inward, the inner container 3 positioned inside thereof is also pushed inward, the accommodation space S is positively pressurized, the slit 18 (discharge port 4a) is opened, and the contents C Is discharged.

  Then, when the deformation of the body portion 2b proceeds by further squeezing, finally, as shown in FIG. 4, the distal ends of the extending portions 5a of the pair of regulating members 5 sandwich the inner container 3 from each other. At the end, further deformation of the body 2b is restricted. Thus, the extension part 5a of the set of regulating members 5 can regulate the deformation amount of the body part 2b by abutting each other with the inner container 3 sandwiched by the deformation of the body part 2b by squeeze. Therefore, according to the squeeze discharge container 1 according to the present embodiment, a relatively large amount of quantified content C can be discharged by a simple operation.

  Thereafter, when the squeeze is released, the body portion 2b is restored, and the inner container 3 is restored along with the restoration, and the accommodating space S is negatively pressured. Due to this negative pressure, the slit 18 (discharge port 4a) is opened, and an amount of air corresponding to the discharge amount of the contents C flows into the accommodation space S from the outside. Thus, the discharged content C is replaced with air.

  The above-described embodiment is merely an example of the embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the gist of the invention.

  For example, the pair of regulating members 5 have the same shape and size as each other in the above-described embodiment, but are not limited to such a configuration. For example, one set of the restricting members 5 may be formed such that one extending portion 5a is longer than the other extending portion 5a. Moreover, although the squeeze discharge container 1 has only one set of regulating members 5 in the above-described embodiment, it may have a plurality of sets of regulating members 5. Further, the extending portions 5a of the plurality of sets of regulating members 5 may be capable of regulating the deformation amount of the body portion 2b due to squeeze to different deformation amounts. In this case, it is preferable that the plurality of sets of regulating members 5 are arranged side by side in the major axis direction in the cross section of the body portion 2b. In addition, the squeeze discharge container 1 has a set of restricting members 5 in the above-described embodiment, but has a single restricting member 5 that does not form a set, and the extension portion 5a causes a squeeze body portion. It may be possible to regulate the deformation amount of 2b. In this case, the extension portion 5a of the single regulating member 5 can regulate the deformation amount of the barrel portion 2b by abutting the inner barrel 3 with the barrel portion 2b opposed thereto by deformation of the barrel portion 2b due to squeeze. May be. Further, the squeeze discharge container 1 may have a plurality of single regulating members 5, and the extending portions 5a of the plurality of regulating members 5 regulate the deformation amount of the body portion 2b due to the squeeze to different deformation amounts. It may be possible. In this case, it is preferable that the plurality of regulating members 5 are arranged side by side in the long axis direction in the cross section of the body portion 2b.

  In the above-described embodiment, the discharge port 4a is configured by the slit 18 of the valve body 4d. However, the discharge port 4a may be configured by the opening, for example, by providing the top wall 12 with a cylindrical discharge tube that divides the opening downstream (upper side) from the slit 18 of the valve body 4d. Moreover, although the valve body 4d is comprised by the slit valve in the said embodiment, it is not restricted to such a structure.

  Although the trunk | drum 2b has the cross section which makes an elliptical shape in the said embodiment, the shape can be changed suitably. For example, the body part 2b may have a cross section that forms a rectangular shape or other flat shape, or may have a cross section that forms a square shape, a regular polygonal shape, a circular shape, or other non-flat shape. .

  The extending portion 5a of the restricting member 5 has a cylindrical shape in the above-described embodiment, but the shape can be changed as appropriate. For example, the extending part 5a may have a rectangular tube shape, or may have a cylindrical shape or a rectangular column shape.
