  In a conventional container with a cap, as a method of holding a cylindrical ironing member at the outlet of the container, a method of holding a hard or semi-rigid packing by press-fitting into the outlet from the outside (see Patent Document 1) ), And a method of forming a collar portion projecting laterally in an annular shape on the outer periphery of both end portions of a semi-rigid or soft cylindrical packing, and holding it by sandwiching an outlet between the collar portions (Patent Document 2) See).

  However, according to these conventional configurations, when the container with a cap is not used, the cap is tightened to the outlet, so that the coating liquid is tightly tightened so as not to leak out from the container. In use, when the cap is untwisted from the outlet and removed, there is a problem that the packing held at the outlet may fall off while temporarily adhering to the cap.

  The dropping of the ironing member is more likely when the coating liquid in the container part exhibits strong adhesion to the packing and the cap.

  The present invention has been made in consideration of the above points, and it is an object of the present invention to propose a container with a cap in which the packing does not fall off when the cap is removed and the sealing power of the packing at the outlet is large. .

In order to solve such a problem, in the present invention, in the container 1 with a cap that fastens the cap 4 with the packing 7 made of a flexible member sandwiched between the outlet 3 of the container portion 2, the packing 7 connects the outlet 3. the outer peripheral surface to the inner surface of the cylindrical outlet member 11 which forms are disposed so as to contact, a cylindrical packing body 13 ing provided member 14 ironing in the interior space, preparative at upper and lower ends of the packing body 13 An annular upper collar 15 and lower collar 16 projecting laterally so as to extend on the upper end surface and lower end surface of the outlet member 11, and a part of the outer peripheral surface of the lower collar 16 outward in the lateral direction And a reinforcing projection 35 integrally formed with the lower flange 16 so as to protrude into the inner surface of the outlet member 11 when the packing 7 is mounted on the inner side surface of the outlet member 11. Protrusion 35 is shaped After the lower part is inserted into the outlet member 11 in a state in which the part including the reinforcing protrusion 35 is formed on the part that has not been deformed so as to be elongated in the vertical direction, When the side portion passes through the outlet member 11 and returns to its original shape, the lower flange portion 16 and the reinforcing projection 35 are extended along the lower end surface of the outlet port 3. a lower flange portion and the reinforcing projection 35 by which to so that to attachment retained between upper and lower ends of the outlet 3 preparative packing 7.

According to the present invention, the reinforcing protrusion is provided integrally with the lower flange so as to protrude outward in a part of the outer peripheral surface of the lower flange of the packing, The lower part is configured to be inserted into the outlet member in a state of being elongated in the vertical direction, including the part formed in the part where the reinforcing protrusion is not formed. Accordingly, when loosening the cap from a state where tightening of the cap sandwiched between the upper end surface of the outlet member preparative upper flange portion, also as the upper flange portion is pulled upwardly to temporarily adhere to the cap, When the reinforcing protrusion comes into contact with the lower end surface of the outlet member or its periphery, it is possible to prevent the packing from coming off from the outlet member with a simple configuration .

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) 1st Embodiment In FIG. 1, 1 shows the container with a cap as a whole, the shaft 5 fixed to the cap 4 from the outlet 3 of the container part 2 which accommodates the mascara as a storage liquid, and its front-end | tip The brush body 6 and the provided brush body 6 are put in and out through the center hole of the packing 7 forming the ironing portion, so that the brush body 6 is immersed in a mascara stored as a storage liquid in the container portion and taken out to the outside. ing.

  As shown in FIG. 2, the take-out port 3 is a cylindrical take-out port formed so as to protrude upward from the upper end of the container part 2 on the center line L1 of the container part 2 made of, for example, a synthetic resin material. The packing 7 which has the member 11 and comprises an iron member in the said outlet member 11 is mounted | worn.

  The packing 7 is formed as a semi-rigid or soft flexible member by molding a resin material such as rubber, elastomer or EVA.

  As shown in FIG. 3, the packing 7 has a cylindrical packing body 13 that extends in the up-down direction, and the inner space of the packing body 13 so that the inner diameter decreases downward on the center line L <b> 1 in the inner space of the packing body 13. The ironing member 14 having a funnel shape is provided so that the upper edge thereof is integrated with the inner wall of the packing body 13.

  Thus, when the brush body 6 provided at the lower end of the shaft 5 is inserted along the center line L1 from above the packing body 13, the ironing member 14 is made of the hair material constituting the shaft 5 and the brush body 6. The shaft 5 and the brush body 6 can be inserted up to a position where the shaft 5 and the brush body 6 are immersed in the coating liquid in the container portion 2 by pushing the center port flexibly.

  An annular upper flange 15 is formed on the upper outer peripheral edge of the packing body 13, and the annular lower surface of the upper flange 15 engages with the upper end surface of the outlet member 11 from above.

  On the other hand, the lower flange 16 is formed on the outer peripheral surface of the lower end portion of the packing body 13 so as to protrude laterally so as to be orthogonal to the center line L1, and the lower flange 16 is formed on the outlet member 11. The lower end surface or the periphery thereof (the lower end surface portion of the outlet member 11 or the joint portion with the shoulder portion 2A of the container portion 2 connected to the outlet member 11) is contacted from below, thereby By sandwiching the upper end surface and the lower end surface of the outlet member 11 by the portion 15 and the lower flange portion 16, the packing 7 is removed while the outer peripheral surface of the packing body 13 is in contact with the inner peripheral surface of the outlet member 11. 3 is obtained.

  A male screw 21 is formed on the outer peripheral surface of the outlet member 11. As shown in FIG. 4, a female screw 22 of the cap 4 fixed to the upper end of the shaft 5 is screwed into the male screw 21. By tightening, the cap 4 can be tightened and held in the outlet member 11 in a state where the shaft 5 and the brush body 6 are inserted into the packing 7 constituting the ironing portion.

  The cap 4 has a cap body 26 (FIG. 4) having a cylindrical appearance formed by drilling a cylindrical internal space 25 from below, and the lower side of the internal space 25 with the center line L2 of the cap body 26 as the center. A female screw 22 is formed around the center line L2 on the surface of the side wall, and the cap body 26 is moved from above to the outlet member 11 so that the center line L2 is along the center line L1 of the outlet member 11 (FIG. 2). By covering, the female screw 22 of the cap body 26 can be screwed into the male screw 21 of the outlet member 11.

  A connecting member 31 is fitted into the upper portion of the internal space 25 (FIG. 4).

  The connecting member 31 has a cylindrical connecting member main body 32, and a disk-shaped pedestal plate portion 33 is integrally formed so as to close the lower end surface thereof. The connecting member main body 32 is an internal space 25 of the cap main body 26. The connecting member main body 32 is assembled together with the cap main body 26 together with the base plate portion 33 by being press-fitted into the inside from below.

  A mounting hole 34 is formed so as to penetrate the center portion of the pedestal plate portion 33, and is welded in a state where the upper end portion of the shaft 5 is inserted into the mounting hole 34. The shaft 5 is fixedly held on the cap body 26 so as to extend on the center line L <b> 2 of the body 26.

  In addition to this, when the female screw 22 of the cap body 26 is screwed into the male screw 21 of the outlet member 11, the outer peripheral portion of the lower surface of the base plate portion 33 comes into contact with the upper flange portion 15 of the packing 7 with good consistency from above. Thus, when the cap 4 is fastened to the container part 2, the flexibility of the upper flange part 15 is used to function as a packing so that the stored liquid in the container part 2 does not leak outside.

  In addition to the above configuration, as shown in FIGS. 3A to 3C, the lower flange portion 16 has a reinforcing projection 35 that protrudes outward in the lateral direction in the range of the substantially semicircular circumference of the outer surface. Is formed.

  This reinforcing projection 35 is formed so that the material constituting the lower collar 16 bulges outward, so that it has the same semi-rigid or soft flexibility as the lower collar 16. Yes.

  In the above configuration, the cap 4 is screwed into the male screw 21 formed around the outlet member 11 in a state where the packing 7 is attached to the outlet member 11 of the container portion 2 as the ironing portion. 2 is put on the outlet 3.

  At this time, the base plate portion 33 of the coupling member 31 of the cap 4 presses the upper flange portion 15 of the packing 7 so as to compress it against the upper end surface of the outlet member 11, thereby utilizing the flexibility of the packing 7. It will be in the state sealed so that the storage liquid in 2 may not leak outside.

  In this state, when the cap 4 is twisted back and the brush body 6 immersed in the coating liquid in the container portion 2 is pulled out, the brush body 6 is pulled out through the ironing member 14 of the packing 7. Since the packing 7 exhibits semi-rigid or soft flexibility, the squeezing member 14 performs an operation such as squeezing the shaft 5 and the brush body 6 while slightly expanding softly.

  At the same time, when the cap 4 is loosened so as to be twisted back from the outlet member 11, when the base plate portion 33 of the cap 4 is separated from the upper flange portion 15 of the packing 7, a part of the adhesive coating solution is adhered. When attached to the upper collar 15, the upper collar 15 temporarily adheres to the base plate 33 and is pulled upward integrally with the base plate 33 of the cap 4. Since the reinforcing projection 35 protrudes outward in the lateral direction from the lower flange portion 16 and abuts against the outlet member of the container portion 2 or the shoulder portion 2A around the outlet member, when the packing 7 is pulled upward, The reinforcing protrusion 35 hits the outlet member of the container part 2 or the shoulder part 2 </ b> A around the container member 2, thereby preventing the packing 7 from being pulled out from the inner space of the outlet member 11.

  According to the above configuration, as the packing 7, a material having a softness sufficient to perform the ironing operation by the ironing member 14 is applied, thereby obtaining a sealing effect by the upper flange 15 and the cap 4. Even when the packing 7 is temporarily attached to the pedestal plate portion 33 and pulled upward when twisting back, the packing 7 is removed as a whole by providing the reinforcing projection 35 on the lower flange portion 16. The possibility of falling off from the member 11 can be effectively prevented.

  At the same time, according to the above-described configuration, the reinforcing protrusion 35 is provided on a part of the lower flange portion 16 (in the case of FIG. 3, a range of about a half circumference), so that the packing 7 is attached to the outlet member 11. When the portion not provided with the reinforcing projection 35 is deformed by pressing inward in the lateral direction from the outside when inserted from above for assembly work for the purpose, the packing 7 as a whole ( At least the lower part can be deformed so as to be elongated in the longitudinal direction, whereby the packing 7 can be easily inserted into the outlet member 11.

  Thus, the packing 7 can be easily mounted so that the lower flange portion 16 provided with the reinforcing projection 35 contacts the lower end surface of the outlet member 11 or the shoulder portion 2A of the container portion 2.

  If the reinforcing protrusions 35 are formed over the entire circumference of the lower flange 16, the reinforcing protrusions 35 are not easily deformed when the packing 7 is inserted into the outlet member 11. Although it cannot be inserted (or extremely difficult), the above-described configuration can effectively solve such a problem.

(2) Other Embodiments FIG. 5 shows another embodiment. As shown in FIG. 5 (A), the packing corresponding to FIGS. Two reinforcing protrusions 41 </ b> A and 41 </ b> B are formed so as to protrude outward in the lateral direction from the outer peripheral surface of the lower flange part 16 with respect to the lower flange part 16 of the packing body 13.

  In this case, the reinforcing protrusions 41A and 41B are arranged on the outer surface circumference of the lower flange 16 so as to face each other with an angular interval of approximately 180 degrees.

  5A, when the packing 7 is attached to the outlet member 11, the portion of the lower flange 16 where the pair of reinforcing protrusions 41A and 41B are not provided is laterally extended from the outside. The outlet member 11 is pushed in while the packing 7 is deformed so as to be elongated in the longitudinal direction as a whole by pressing inward (at least the lower part).

  Thus, if the packing 7 is inserted until the upper flange 15 comes into contact with the upper end surface of the outlet member 11 in the same manner as described above with reference to FIG. 2, the lower flange 16 or the reinforcing protrusions 41A and 41B become the container portion. When the packing body 13 returns to a state where it is not deformed by its elasticity when it comes to a position where it comes into contact with the take-out member 11 of the shoulder 2A of the second shoulder 2 or its lower surface, the upper collar 15 and the lower collar 16 Or the packing 7 is attached to a predetermined position of the outlet member 11 in such a state that the outlet member 11 is sandwiched between the reinforcing protrusions 41A and 41B.

  5A, even when the cap 4 is unscrewed in the sealed state in which the cap 4 is screwed into the male screw 21 of the outlet 3 and the pedestal plate portion 33 is attached to the upper flange 15, the pedestal Even if the plate portion 33 is temporarily attached to the upper flange portion 15 of the packing 7 and the packing 7 is pulled upward, in addition to the lower flange portion 15, a reinforcing protrusion 41 </ b> A that protrudes laterally from the outer peripheral surface thereof. And 41B can contact | abut to the lower face of the lower collar part 16 or the shoulder part 2A of the circumference | surroundings, and it can prevent that packing 7 falls out upwards.

FIG. 5 (B) shows still another embodiment. In this case, as shown in FIG. 5 (A), the same reference numerals are assigned to the corresponding portions, and four reinforcing protrusions are formed on the outer peripheral surface of the lower flange portion 16. 42A~42D is formed so as to protrude outward in the transverse direction at a position to maintain the angular spacing of approximately 90 degrees is divided into four outer peripheral surface.

  According to the configuration of FIG. 5B, when the packing 7 is mounted on the outlet member 11, the packing 7 is pressed inward in the lateral direction on the portions where the reinforcing protrusions 42A to 42D are not formed. Is pushed into the outlet member 11 in a state where it is deformed so as to be elongated in the longitudinal direction as a whole (at least the lower part), thereby the upper flange 15 of the packing 7 in the same manner as described above with reference to FIG. And the outlet member 11 is mounted between the lower flange 16.

  In this mounted state, the reinforcing protrusions 42A to 42D abut against the outlet member 11 of the container part 2 or the inner surface of the shoulder part 2A around the container part 2 at a position where the protrusions 42A to 42D spread laterally outward from the outer peripheral surface of the lower flange part 16. Thus, when the cap 4 is twisted back, even if the upper flange 15 is temporarily attached to the base plate portion 33 of the cap 4, it is possible to prevent the packing 7 from falling off.

  FIG. 5 (C) shows still another embodiment. As shown in FIG. 5 (A), parts corresponding to those in FIG. 43A to 43H are formed so as to protrude outward in the lateral direction at a position where the outer peripheral surface of the lower flange portion 16 is divided into eight to maintain an angular interval of approximately 45 degrees.

  5C, when the packing 7 is attached to the outlet member 11, the portion of the lower portion of the packing 7 where the reinforcing projections 43A to 43H are not formed is placed in the lateral direction. By pressing in the direction, the packing 7 as a whole (at least the lower part) can be pushed into the outlet member 11 while being deformed so as to be elongated in the vertical direction.

  Thus, in a state where the outlet member 11 is sandwiched between the upper flange portion 15 and the lower flange portion 16, the eight reinforcing projections 43 </ b> A to 43 </ b> H are provided at the outer position of the lower flange portion 16 and the outlet member 11 of the container portion 2 or its surroundings By contacting the lower surface of the shoulder portion 2A, the packing 7 can be prevented from falling off even if the base plate portion 33 is temporarily attached to the upper flange portion 15 when the cap 4 is twisted back.

  In the above-described embodiment, the reinforcing protrusions 35 (FIG. 3), 41A to 41B (FIG. 5A), 42A to 42D (FIG. 5B), 43A to 43H (FIG. 5C) As a semi-rigid or soft lower flange part 16, the same member is formed by projecting outward in the lateral direction. Instead, the reinforcing projection part is made of a resin that is harder than other parts of the material. You may make it raise the hardness of the protrusion for a reinforcement by carrying out double molding or two-color molding with a material.

  In this way, when the cap 4 is twisted back, even if the upper flange 15 of the packing 7 temporarily adheres to the pedestal plate 33, it can be more strongly prevented from falling off by the reinforcing protrusion having high hardness. .

  Furthermore, in the above-described embodiment, the present invention is applied to a container 1 with a cap in which a cap 4 having a shaft 5 with a brush body 6 attached to the tip is screwed into a container 2 that stores mascara as a storage liquid. Although the case where it is applied is described, the present invention is not limited to a container for mascara liquid, but the liquid stored in the container is sealed by tightening the cap, such as hair dyeing liquid or cosmetic liquid, and the cap This can be widely applied to the case where packing is provided on the outlet member so that the stored liquid in the container does not accidentally spill outside when the container is loosened.

  Furthermore, in the above-described embodiment, the case where the ironing member 14 is provided as the space limiting member in the packing 7 has been described, but this is omitted or replaced with one or more in the packing or in the upper end portion. When the container part 2 falls down with the cap or the cover plate having a through-hole, the stored liquid in the container part 2 (for example, liquid such as lotion or drinking water) Even if the space of the packing 7 is limited so as not to flow out in large quantities, the same effect as described above can be obtained.

  INDUSTRIAL APPLICABILITY The present invention can be used for a container with a cap that fastens a cap to a container part.
