JP 2004-339216 A

  In the conventional squeeze foamer container, the foam cap that discharges the liquid supplied from the squeeze container body in the form of foam is supplied to the gas-liquid mixing chamber in the former cap, and the liquid in the container body is passed through the dip tube. In addition to supplying air, the air in the head space in the container body is supplied from the air inflow hole opened in the gas-liquid mixing chamber, and the liquid and air are mixed in the gas-liquid mixing chamber and discharged through the mesh member. ing.

  For this reason, when the first agent and the second agent are mixed in the container body, if the mixed liquid is foamed, the air inflow hole is blocked by the foam, and the air in the head space in the container body is evacuated. There is a problem that it is difficult to supply to the liquid mixing chamber and the desired gas-liquid mixing ratio cannot be obtained, so that soft bubbles are not obtained or dripping occurs.

  On the other hand, the present invention provides a squeeze foamer container that can be stably discharged in the form of foam with the desired foam quality even when the liquid that easily foams is discharged simply by mixing or stirring. The purpose is to do.

  The inventor of the present invention has a so-called two-layered container body of an squeeze foamer container, which is composed of an outer container and an inner bag (in this specification, in addition to a bag-like container, a thin container made of a flexible resin is also called a “bag”). If air between the outer container and the inner bag is used as the air to be supplied to the gas-liquid mixing chamber using a heavy container, even if the liquid discharged in the container body is foamed, the air to the gas-liquid mixing chamber It has been found that the liquid can be stably ejected in the form of foam without hindering the supply.

  That is, the present invention is a squeeze foamer container including a container main body that contains a liquid and a foamer cap that discharges the liquid in the container main body in a foam shape, and the container main body has an squeeze property and an outer container. The inner cap has a gas-liquid mixing chamber and a mesh member, and a liquid inflow hole for allowing the liquid in the inner bag to flow into the gas-liquid mixing chamber and air between the outer container and the inner bag. There is provided a squeeze foamer container provided with an air inflow hole for inflow.

  According to the squeeze foamer container of the present invention, the container body that stores the liquid is composed of the outer container and the inner bag, and the air between the outer container and the inner bag is supplied to the gas-liquid mixing chamber of the former cap. Therefore, the liquid can be stably discharged in the form of foam with the desired foam quality regardless of the presence or absence of foaming of the liquid in the container body.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 1 is a perspective view (a) and sectional views (b) and (c) of a squeeze foamer container 1A according to an embodiment of the present invention, and FIG. 2 is an enlarged sectional view of the vicinity of the gas-liquid mixing chamber. is there.

  The squeeze foamer container 1A includes a container main body 2 that stores a liquid A and a former cap 10 that is attached to the mouth of the container main body 2.

  The container body 2 is a delami bottle in which the outer container 3 and the inner bag 4 are easily laminated. Among these, the outer container 3 is made of a synthetic resin such as polyethylene or polypropylene having a thickness of 0.4 to 1.5 mm, and has a squeeze property that is deformed by pressing and is restored by releasing the pressing. On the other hand, the inner bag 4 has a thickness of 0.1 to 0.5 mm and is made of a resin such as nylon, ethylene vinyl alcohol copolymer, polyethylene terephthalate, etc., which has low compatibility with the constituent resin of the outer container 3, and is freely deformable. It is.

  In the vicinity of the mouth of the outer container 3, an internal space 5 between the outer container 3 and the inner bag 4 is communicated with the outside of the outer container 3, and the outer container 3 is placed between the outer container 3 and the inner bag 4. Ventilation holes 6 are provided to allow the air to be introduced.

  In addition, the outer container 3 and the inner bag 4 form an adhesive band 7 bonded to each other in a band shape. The adhesive band 7 is provided in the longitudinal direction of the container body 2 at a position facing the side wall of the container body 2. Thereby, when the inner bag 4 is peeled from the outer container 3, as shown in FIG. 1C, the inner bag 4 is flattened so that the distance between the side walls between the adhesive band becomes narrow as shown in FIG. Since the inner space 5 is formed between the outer container 3 and the inner bag 4 by being flattened in this way, the inner bag 4 is peeled off from the outer container 3 when the delami bottle is manufactured. 3 and the inner bag 4 can secure an initial space, and the air in the inner space 5 between the outer container 3 and the inner bag 4 can be supplied to the former cap 10 from the first squeeze of the container body 2. It becomes.

  As shown in FIG. 3, the adhesive band 7 may be formed in a single line in the longitudinal direction of the container body 2. In this case, since the entire circumference other than the adhesive band 7 of the inner bag 4 is peeled off from the outer container 3, it is possible to secure the initial inner space 5 as shown in FIG.

  Note that the outer container 3 and the inner bag 4 are also bonded to each other at their bottoms.

  Such a delami bottle has, for example, a cylindrical parison for forming an outer container and a cylindrical parison for forming an inner bag with a band-shaped adhesive resin for forming an adhesive band 7 interposed therebetween. It can be obtained by coextrusion, sealing both parisons by pinch-off, and blow molding.

  On the other hand, the former cap 10 discharges the liquid A in the container main body 2 in the form of bubbles, and the cylindrical gas-liquid mixing chamber 12 that mixes the liquid A and the air B in the cylindrical housing 11. , And a mesh member 13 downstream of the gas-liquid mixing chamber 12. The discharge channel 14 a protrudes upward from one end of the housing 11 and bends in the horizontal direction in the middle. The other end inner wall has a screw portion 15 to be screwed into the peripheral wall of the mouth of the container body 2.

  The former cap 10 includes a liquid inflow hole 17 through which the liquid A flows into the gas-liquid mixing chamber 12 from the container body 2 through the dip tube 16, and the air B in the internal space 5 between the outer container 3 and the inner bag 4. An air inflow hole 18 is provided separately.

  More specifically, a liquid inflow hole 17 is provided on the bottom surface of the cylindrical gas-liquid mixing chamber 12. Below that, a dip tube 16 is joined via a frustoconical joint 19 whose diameter is reduced downward. On the other hand, the air inflow hole 18 is provided in the side wall of the cylindrical gas-liquid mixing chamber 12, and the liquid inflow hole 17 and the air inflow hole 18 are separated from each other.

  In addition, the housing 11 is a seal portion that is airtightly adhered to the outer container 3 between the vent hole 6 and the screw portion 15 so as to define an in-housing space 11 a that includes the air inflow hole 18 and the vent hole 6. More specifically, the seal portion 20 includes an annular packing 20a. Furthermore, when the housing 11 is screwed into the container body 2, the plate-like member 21 that forms the bottom surface of the gas-liquid mixing chamber 12 hits the top surface of the mouth of the container body 2, The mouth of the container body 2 is closed, and the abutting portion is also provided with an annular packing 23 as a seal member. An annular rib 22 is provided on the lower surface of the plate-like member 21 for alignment with the mouth of the container body 2 and for sealing.

  On the top surface of the housing 11, an intake hole (hereinafter referred to as a valved intake hole) 24 with an intake valve is provided. By appropriately adjusting the hardness of the valve body of the intake hole 24 with the valve according to the viscosity of the liquid A and its bubbles, etc., when the housing inner space 11a is depressurized, the air inlet hole 18 through the discharge port 14 is provided. It is possible to allow the air outside the housing to flow into the housing inner space 11a through the valved intake holes 24 in preference to the air inflow path to the housing inner space 11a via It is possible to prevent the air inflow hole 18 from being clogged with the liquid A or its bubbles when returning to step (b).

  As a method of using the squeeze foamer container 1A, first, the body part of the container body 2 is pressed and recessed. Thereby, the inside of the inner bag is pressurized, and the liquid A is supplied to the gas-liquid mixing chamber 12 from the liquid inflow hole 17 through the dip tube 16. In addition, the inner space 5 between the outer container 3 and the inner bag 4 and the inner space 11 a are pressurized by this pressing, and the air B is supplied from the air inflow hole 18 to the gas-liquid mixing chamber 12. Accordingly, the liquid A is mixed with the air B in the gas-liquid mixing chamber 12 and discharged from the discharge port 14 in the form of bubbles through the mesh member 13. Next, when the pressing of the body portion is released, the outer container 3 returns to the shape before pressing due to elasticity, and the internal space 5 between the outer container 3 and the inner bag 4 is decompressed. Therefore, air flows into the housing inner space 11a from the valved intake hole 24, and further enters the inner space 5 from the vent hole 6 to return the inner space 5 to normal pressure. Thereby, the inner bag 4 is crushed by the discharge amount of the liquid A. Thereafter, by repeatedly pressing and releasing the body portion of the container body 2, the liquid A in the container body can be discharged in the form of foam.

  In this case, the air supplied to the gas-liquid mixing chamber 12 is not air that exists in the head space of the inner bag 4 but air that is supplied by pressing the inner space 5 between the outer container 3 and the inner bag 4. Therefore, even when the liquid A is highly bubble-like, such as a mixed solution of a two-component hair cosmetic containing a surfactant, and the foam in the container body 2, the air inflow hole 18 is blocked with foam. It will not come off. Therefore, the gas-liquid mixing ratio (volume ratio of air to the liquid constituting the foam) can be maintained at a desired value. For example, the gas-liquid mixing ratio 8 is maintained from the start of use to the end of the squeeze foamer container 1A. It becomes possible to stably discharge bubbles having high foam quality of ~ 45.

  The squeeze foamer container of the present invention can take various forms.

  For example, as the container body 2, a double container in which an outer container having squeeze properties and a deformable inner bag are independently formed may be used instead of the above-described delamination bottle.

  Moreover, regarding the configuration of the mouth portion of the container body 2, as shown in FIG. 2, the top surface of the mouth portion of the outer container 3 and the top surface of the mouth portion of the inner bag 4 form one surface, so-called flush. When the former cap 10 is screwed into the container body 2, they may be in close contact with the plate-like member 21 via the annular packing 23, and like the squeeze foamer container 1B in FIG. A flange 8 protruding outward may be formed at the mouth of the bag 4, the top of the mouth of the outer container 3 may be abutted against the lower surface of the flange 8, and only the flange 8 of the inner bag 4 may be in close contact with the annular packing 23. . Further, like the squeeze foamer container 1C of FIG. 5, an annular groove is formed on the lower surface of the flange 8 projecting outside the mouth portion of the inner bag 4, and the mouth peripheral wall of the outer container 3 is fitted into the annular groove. You may let them.

  Further, as in the squeeze foamer container 1 </ b> D of FIG. 6, a liquid suction valve 25 may be provided in the liquid inflow hole 17 instead of the dip tube 16. As the liquid suction valve 25, a check valve that allows the liquid A to be supplied from the container body 2 to the gas-liquid mixing chamber 12 and prohibits the flow in the reverse direction is used. As shown in FIG. 2, when the dip tube 16 is provided, the squeeze foamer can be prevented from being blown out easily in the first use of the squeeze foamer container, whereas when the liquid suction valve 25 is provided, the squeeze foamer is provided. The foam discharged from the beginning of use of the container can be made to have high foam quality, and not only the container body 2 can be used upright but also upside down.

  The squeeze foamer container 1E of FIG. 7 is configured such that a check valve 26 is provided between the gas-liquid mixing chamber 12 and the discharge port 14, and the valve body is integrated with the valve body of the valved intake hole 24. . By providing the check valve 26 between the gas-liquid mixing chamber 12 and the discharge port 14 in this way, bubbles remaining in the discharge hole 14 when the outer container 3 is squeezed and then the pressure is released. It is sucked to the gas-liquid mixing chamber 12 side (so-called squeeze back), and the air inflow hole 18 can be prevented from being blocked by bubbles.

  In this case, as the check valve 26, it is preferable to provide a check valve that does not deteriorate the foam quality when the foam is discharged.

  The squeeze foamer container 1F in FIG. 8 is provided with mesh members 13a and 13b in multiple layers downstream of the gas-liquid mixing chamber 12, thereby improving the foam quality. In this case, the upstream mesh member 13a that defines the gas-liquid mixing chamber 12 improves the mixing efficiency of the liquid A and the air B in the gas-liquid mixing chamber 12, and therefore, compared with the downstream mesh member 13b. It is preferable to reduce the diameter of the flow path formed by the mesh member.

  The squeeze foamer container 1G of FIG. 9 is provided with mesh members 13a and 13b in a multilayer on the downstream side of the gas-liquid mixing chamber 12, and in order to improve the foam quality when the mesh member is provided in a multilayer. , The gap between the mesh members 13a and 13b is widened. For this purpose, the holding wall 27 of the mesh members 13a and 13b extends from the plate-like member 21 in which the liquid inflow hole 17 is opened to the discharge hole 14. It rises to the vicinity of the base of the horizontal discharge flow path 14a.

  In order to improve the foam quality, the squeeze foamer container 1H shown in FIG. 10 has a plate-like member 21 on which the holding wall 27 of the mesh members 13a and 13b rises, in order to increase the space between the mesh members 13a and 13b. The inflow hole 17 is lowered to the bottom side of the opening surface of the inner bag 4. As a result, the head space of the inner bag 4 is reduced, so that the first use of the squeeze foamer container can be reduced.

  The squeeze foamer container 1I in FIG. 11 has a check valve 26 similar to the squeeze foamer container 1E in FIG. 7 between the mesh member 13b downstream of the squeeze foamer container 1H in FIG. And improve the foam quality by widening the interval between the multi-layer mesh members 13a and 13b, reducing the head space in the inner bag 4 to reduce the first use of the squeeze foamer container, and squeeze back Is also prevented.

  A squeeze foamer container 1J in FIG. 12 is the squeeze foamer container 1F in FIG. If the intake hole 24 with a valve is formed on the top surface of the housing 11, dust or dirt accumulates in the intake hole 24 with the valve during the flow of the squeeze foamer container, which may cause malfunction of the valve. By providing the air intake hole 24 on the side surface of the housing 11, the risk of such malfunction can be eliminated.

  The squeeze foamer container 1K of FIG. 13 is provided with a container body 2 in order to eliminate the possibility of malfunction of the valved intake hole 24 due to dust or dirt when a double container is used instead of a Delami bottle. An intake hole 24 with a valve is provided on the bottom surface.

  The squeeze foamer container of the present invention can take various modes with respect to the vent hole 6 that opens near the mouth of the outer container 3 of the container body 2.

  The squeeze foamer container 1L of FIG. 14 is provided with a slit 9 in the flange 8 protruding outside the mouth portion of the inner bag 4, and the slit 9 introduces air between the outer container 3 and the inner bag 4. A gap is formed between the inner wall of the mouth of the outer container 3 and the inner wall of the mouth of the inner bag 4 so that the pores 6 are formed, and the edge of the mouth of the outer container 3 is abutted against the flange 8. As a result, as indicated by an arrow in FIG. 14B, the air B between the outer container 3 and the inner bag 4 is extruded from the vent hole 6 formed by the slit 9, or vice versa. It is possible to introduce the air outside the outer container 3 between the inner bag 4 and the inner bag 4, that is, the air in the housing inner space 11 a when the former cap 10 is attached.

  It is preferable to form the air holes 6 with the slits 9 in this manner because the number of steps for forming the air holes 6 on the side surface of the outer container 3 is reduced, and productivity can be improved.

  Further, in the squeeze foamer container of the present invention, the lower body diameter of the container body 2 is smaller than the upper part of the container body 2 as in the squeeze foamer container 1M of FIG. It is preferable to use a reverse taper type. Accordingly, when the inner bag 4 is filled with the liquid A when the container body is a delami bottle, the force in the direction of peeling the inner bag 4 from the outer container 3 on the shoulder of the inner bag 4 due to the weight of the liquid A. Take it. Therefore, as shown in FIG. 2B, an internal space 5 of the container body 2 is formed, and air supplied to the gas-liquid mixing chamber 12 can be secured even at the beginning of use of the squeeze foamer container. It can be reduced. Further, even in the double container in which the outer container 3 and the inner bag 4 are independently formed, the inner space 5 is formed in the shoulder portion of the container body 2 by filling the inner bag 4 with the liquid A. Similarly, idling can be reduced.

  The squeeze foamer container 1N of FIG. 16 is a barrel shape in which the outer shape of the container body 2 is thicker than the upper part and the lower part. By making the barrel shape, the deformation amount of the container body 2 at the time of squeezing can be increased, so that the operation of the hand performing squeezing becomes easy, and the amount of foam discharged by one squeezing is increased. Can do. Furthermore, by using the barrel shape, the filling of the liquid A facilitates formation of the internal space 5 in the center of the trunk as shown in FIG.

  In the present invention, the various aspects described above can be combined as appropriate.
