No. 7-6101

  The present applicant has previously filed Japanese Patent Application No. 2009-265588 (hereinafter referred to as “prior application”). The container with a cap of the prior application is provided between the ceiling part of the cap body and the outer periphery of the opening cylinder part of the container, and an engagement part that can be detached by raising the cap, and an elastic ring body assembled to the cap body. A fitting portion provided between the outer periphery of the container opening cylindrical portion and detachable by elastic deformation in the radial direction of the elastic ring body, i.e., the fitting portion raises the cap to disengage the engaging portion. Because it is a mechanism that does not separate without applying a vertical force to the vertical force to separate, even if a force that raises only the cap without elastically deforming the elastic ring body, It has the feature that the airtightness inside the container is maintained to some extent.

  However, in the container with a cap of the prior application, the cap main body and the elastic ring body are arranged so that the elastic ring body is arranged along the inner periphery of the cap main body body, and the two protrusions provided at the opposing positions on the outer periphery of the elastic ring body. The push button is assembled by exposing two opposing through-holes provided in the cap main body, and at this time, the fitting protrusion constituting the fitting portion is the convex push button of the elastic ring body. It is formed in a position orthogonal to. This is a positional relationship required to deform the elastic ring body by pressing the push button in the radial direction and horizontally move the fitting protrusion outward in the radial direction. When the pulling or the internal pressure of the container increases and the force to push up the cap from the inside acts strongly, the elastic ring body is opposed to the fulcrum with the push button assembled to the cap body through the two through holes. It may be deformed so as to bend downward toward the fitting portion. When the elastic ring body bends up and down, the release strength of the engaging part is set weak, so that the cap body can be moved up and down without removing the fitting part. From various investigations, the phenomenon that the tightness between the sealing member provided on the ceiling of the container and the container opening cylinder is weakened and the hermeticity inside the container is lost, for example, occurs during air transportation with large atmospheric pressure changes. It was revealed.

  Hereinafter, a preferred embodiment of a container with a cap according to the present invention will be described in detail with reference to the accompanying drawings. 1 is an overall perspective view of a container with a cap according to the present embodiment, FIG. 2 is an exploded perspective view of the container with a cap viewed from below, and FIG. 3A is a side view of a top plate portion of the cap provided with an elastic ring body. , (B) is a side sectional view of the top plate part, (c) is a side view of the cylindrical body part of the cap, (d) is a side sectional view of the cylindrical body part, (e) is a side view of the container body, 4 is a partial bottom view of the cap, FIG. 5 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 6 is a cross-sectional view taken along line BB in FIG.

  The cap-equipped container 1 is mainly composed of a container body 2 that accommodates the contents therein, and a top plate part 5 having a cylindrical body 3 and an elastic ring body 4, and is a cap that is attached to the container body 2 from above. 6.

  The container body 2 is formed in the form of a jar or a hollow cylinder using a synthetic resin, metal or glass as a material. The container body 2 includes a neck portion 7 with a small diameter, a cone surface 8 that is extended downward, and a body portion 9 with a large diameter in order from top to bottom. In the illustrated example, the container body 2 having a circular planar outer contour is shown, but it may be polygonal or elliptical.

  An opening 10 for taking out the contents is formed at the upper end of the neck 7. The cone surface 8 is formed below the neck portion 7 so as to be located under the opening 10. The cone surface 8 has a small outer diameter on the upper side and a larger outer diameter on the lower side, and forms a ring-shaped slope that is inclined outwardly downward. In the illustrated example, the cone surface 8 is formed over the entire circumference of the container body 2.

  The cap 6 is made of synthetic resin or metal and is attached to the container body 2 to seal the opening 10. In the illustrated example, the cap 6 having a circular planar outer contour is shown, but may be formed in a polygonal shape or an elliptical shape in accordance with the container body 2.

  The cylindrical body 3 is an inner cylinder 11 having a hollow cylindrical shape, and is connected to the outer cylinder 11 via a support 12 and is provided inside the outer cylinder 11, and surrounds the neck 7 of the container body 2. It is comprised from the cylinder 13 and the top plate 14 which seals the upper opening of the inner cylinder 13, and faces the opening part 10 of the neck part 5. FIG.

  On the lower surface of the top plate 14, a plate-like seal 15 that is in close contact with the opening 10 or an uneven packing 15 that matches the diameter of the opening 10 is provided. The outer cylindrical body 11 is formed with a pair of cutout portions 16 in which a part of the lower end surface is cut away from each other in the diameter direction. Instead of this, the cutout portion 16 may be formed as a through hole 50 facing the outer cylinder 11 as shown in a modified example in FIG. When the outer peripheral edge 5 a of the top plate portion 5 is fitted into the upper end circumferential groove 17 of the outer cylinder body 11, the top plate portion 5 is integrally assembled to the cylindrical body portion 3 so as to cover the top plate 14.

  A pair of flexible pieces 18 are suspended from the top plate portion 5 so as to match the positions of the pair of cutout portions 16 or the through holes 50 of the outer cylindrical body 11 so as to hang around the flexible pieces 18. An elastic ring body 4 that is elastically deformable is formed, whereby the elastic ring body 4 is formed integrally with the top plate portion 5. The elastic ring body 4 has a planar outer contour formed in a circular shape. The elastic ring body 4 is not limited to a circular shape, and may be formed in a polygonal shape or an elliptical shape. The elastic ring body 4 can be variously deformed freely and can be elastically deformed in a diameter direction substantially perpendicular to the pressing direction when pressed from any diameter direction.

  The elastic ring body 4 is positioned between the container main body 2 and the outer cylinder body 11 with the inner cylinder body 13 interposed therebetween. A pair of push buttons 19 are integrally formed on the outer peripheral surface of the elastic ring body 4 so as to be continuous with the flexible piece 18 and facing outward. However, the elastic ring body 4 does not necessarily have to be formed integrally with the top plate portion 5, and there is no flexible piece 18, and when the top plate portion 5 and the elastic ring body 4 are separate bodies, the elastic ring body 4 is elastic first. The ring body 4 is disposed between the outer cylindrical body 11 and the inner cylindrical body 13 of the cylindrical body 3, and then the top plate part 5 is fitted into the upper peripheral groove 17 of the outer cylindrical body 11, It may be fitted by ultrasonic welding or the like.

  That is, the cap 6 is composed of two parts, a first part including the cylindrical body part 3 having the support part 12 and a second part including the top plate part 5 having the elastic ring body 4. When assembled integrally so that the lower end portion of the elastic ring body 4 is positioned on the support portion 12, or the cylindrical body portion 3 having the support portion 12, the elastic ring body 4, and the top plate portion 3. The elastic ring body 4 may be integrally assembled to the cap 6 in a state in which the elastic ring body 4 is in contact with the support portion 12 of the cylindrical body 3.

  The push button 19 is inserted into the relief hole 20 formed in the inner cylinder 13 when the top plate part 5 is assembled to the cylindrical body part 3, and thereby the cap is inserted through the notch part 16 or the through hole 50. 6 Exposed outward. The push button 19 is pressed from the outside of the cap 6 toward the inside of the cap 6, thereby elastically deforming the elastic ring body 4.

  As described above, the notch portion 16 may be not the notch but the through hole 50 opposed to the outer cylinder 11, but when the through hole 50 is used, the size of the push button 19 is, for example, When the finger is smaller than the finger that presses it, the push button 19 cannot be pushed further when it is flush with the outer wall surface of the outer cylinder 11. However, if a part of the outer cylinder 11 is lacking like the notch 16, the push button 19 can be pressed further inward from the wall surface of the outer cylinder 11, thereby improving the pressing operability. In addition, since the movable range of the elastic ring body 4 can be expanded, the cutout portion 16 is preferable.

  The lower end of the push button 6 formed on the elastic ring body 4 is brought into contact with the cone surface 8. Further, the elastic ring body 4, specifically, the push button 6 and the container body 2, are provided with a lifting means for raising the cap 6 by the elastic ring body 4 and the cone surface 8.

  That is, when the elastic ring body 4 is elastically deformed by the push button 19, the elastic ring body 4 urges along with the push button 19 along the cone surface 8 from the lower side to the upper side. Accordingly, the cap 6 to which the elastic ring body 4 and the push button 19 are assembled is pushed upward through the top plate portion 5.

  In this embodiment, the cone surface 8 is formed only on the container body 2, but the cone surface may also be formed so as to face each other inside the push button 19 of the elastic ring body 4. . Alternatively, a cone surface may be formed only on the push button 19, and the container body 2 may be provided with a squaring means that abuts against the cone surface to constitute a push-up means.

  An engaging portion is provided between the inner cylindrical body 13 of the cap 6 and the container main body 2. The engaging portion is formed on the neck portion 7 of the container body 2 over the entire circumference thereof, and is formed on the inner cylindrical body 13 via the slit 22 so as to be detachably engaged with the annular protrusion 21. It is comprised from the engagement piece 23 which can be elastically deformed. A plurality of engagement pieces 23 are formed at appropriate intervals in the circumferential direction of the inner cylinder 13 such as avoiding the position of the push button 19 and the position of the fitting protrusion 24 of the elastic ring body 4 described later.

  When the cap 6 is attached to the container main body 2, the engaging portion 23 engages with the annular protrusion 21 and holds the cap 6 on the neck 7 of the container main body 2 in this engaged state. In the engaging portion, the engaging piece 23 is detached from the annular protrusion 21 by the raising action of the cap 6, and thereby the cap 6 is detached from the container body 2.

  A fitting portion is provided between the elastic ring body 4 of the cap 6 and the container body 2. The fitting portion is formed with an annular protrusion 21 with which the engagement piece 23 engages, and a window hole 25 formed in the inner peripheral surface of the elastic ring body 4 toward the inner side in the radial direction. And a fitting piece 24 that is detachably fitted to the annular protrusion 21. The fitting piece 24 is provided so as to match the position of the window hole 25 formed in the inner cylinder 13 while avoiding the positions of the push button 19 and the engaging piece 23.

  When the cap 6 is attached to the container main body 2, the fitting portion engages with the engaging portion, and the fitting piece 24 fits into the annular protrusion 21, and the elastic ring body 4 is attached to the container main body 2 in this fitted state. Thus, the cap 6 is fitted to the container body 2.

  In the fitting portion, when the elastic ring body 4 is elastically deformed, the fitting piece 24 moves radially outward of the neck portion 7 and is detached from the annular protrusion 21, whereby the elastic ring body 4 is removed from the container body 2. break away. Therefore, the cap 6 is raised by elastically deforming the elastic ring body 4 with the push button 19 and releasing the fitting portion.

  The fitting strength of the fitting portion and the engagement strength of the engaging portion will be described. The fitting portion is separated by the elastic deformation action of the elastic ring body 4 instead of the elastic action of the fitting piece 24, and on the other hand, the engagement The part is separated by the elastic deformation action of the elastically deformable engagement piece 23, and the release strength of the fitting portion is higher than the release strength of the engagement portion when the cap 6 is lifted. ing. The releasing strength of the engaging portion is good enough to allow the cap 6 to easily lift and release smoothly when the elastic ring body 4 is pressed. However, when the release strength is too weak, the fitting between the cap 6 and the container body 2 depends only on the fitting piece 24 formed on the push button 19. The fitting piece 24 is preferably at two positions orthogonal to the push button 19, but the cap 6 is easy to tilt with respect to the container main body 2 alone, and the airtightness cannot be stably maintained without being easily detached. Therefore, it is necessary to adjust the release strength based on this.

  Even if only the cap 6 is pulled upward without pressing the push button 19, the fitting portion does not release as much as possible in order to prevent the engagement portion from being unintentionally released. It is preferable that the elastic ring body 4 has a strength that allows it to be easily detached when the elastic ring body 4 is deformed. These strength adjustments are made by adjusting the amount of engagement between the engaging piece 23 and the annular protrusion 21 or between the fitting piece 24 and the annular protrusion 21 and the contact inclination angle.

  More specifically, the releasing strength of the engaging portion is preferably 1N to 15N, and the releasing strength of the fitting portion is preferably 10 N or more in a state where the elastic ring body 4 is not intentionally elastically deformed in the radial direction.

  In order to more clearly distinguish the engagement portions and the release strengths of the fitting portions, two annular protrusions 21 may be separately formed on the container body 2, and the lengths and inclination angles of the protrusions may be changed.

  The support part 12 which connects the outer cylinder 11 and the inner cylinder 13 of the cylindrical body 3 is mounted on the container body 2 with a cap 6 integrally formed with the top plate 14 and the cylindrical body 3. In a state, the elastic ring body 4 is provided at a position where the lower end surface of the elastic ring body 4 comes into contact with the elastic ring body 4 so as to support the elastic ring body 4. If the support portion 12 is not properly in contact with the elastic ring body 4, when a force is applied to remove the cap 6 from the container body 2 without using the push button 19, the force is It is transmitted from the cylindrical body 3 to the elastic ring body 4 through two flexible pieces 18 formed on the top plate 5. On the elastic ring body 4, since the two fitting pieces 24 that hold the fitting with the container body 2 are formed at positions orthogonal to the flexible piece 18, the elastic pieces originally formed so as to be elastically deformable. The ring body 4 is bent in the vertical direction by the force acting on the ring body 4. Then, only the engaging part with weak release strength is slightly separated while the fitting part is held, and the airtightness inside the container body 2 is lowered. If the support portion 12 is in contact with the elastic ring body 4, when a force is applied to remove the cap 6 from the container body 2, the force is supported from the cylindrical body portion 3 without the flexible piece 18. It is transmitted to the entire elastic ring body 4 through the part 12. And since the support part 12 is supporting the elastic ring body 4, the elastic ring body 4 does not bend, Therefore The airtightness inside the container main body 2 can be hold | maintained highly.

  Next, the effect | action of the container 1 with a cap concerning this embodiment is demonstrated. First, when the cap 6 is assembled, the top plate portion 5 is pushed in from above the cylindrical body portion 3, and the outer peripheral edge 5a of the top plate portion 5 is fitted into the upper end circumferential groove 17 of the outer cylinder body 11, thereby The top plate part 5 is assembled integrally with the cylindrical body part 3.

  During the pushing operation, the elastic ring body 4 of the top plate part 5 is positioned between the outer cylinder body 11 and the inner cylinder body 13 of the cylindrical body section 3, and a push button 19 is formed on the inner cylinder body 13. The fitting piece 24 is positioned to face the window hole 25 of the inner cylinder 13 while being fitted into the notch 16 or the through hole 50 through the relief hole 20. Inside the cap 6 in which the top plate portion 5 and the cylindrical body portion 3 are integrated, a push button 19, an engagement piece 23, and a fitting piece 24 are appropriately arranged around the neck portion 7. At this time, the lower end portion of the elastic ring body 4 is supported while being always in contact with the support portion 12 that connects the outer cylinder body 11 and the inner cylinder body 13 of the cylindrical body 3.

  When the cap 6 is attached to the container body 2, the cap 6 is put on and pushed down from above the container body 2. When the cap 6 is pushed down, the engaging piece 23 of the engaging portion is elastically deformed to engage with the lower side of the annular protrusion 21, and the elastic ring body 4 is elastically deformed so that the fitting piece 24 is below the annular protrusion 21. Mates to the side.

  The cap 6 is held horizontally by the container main body 2 by the engagement of the engaging portion, and the cap 6 is fitted to the container main body 2 via the elastic ring body 4 by the fitting of the fitting portion. Then, the packing 15 provided on the cap 6 via the elastic ring body 4 allows the packing 15 of the cap 6 to be tightly held in the opening 10 of the neck 7 so that the airtightness in the container body 2 is maintained. Is done.

  When removing the cap 6 attached to the container body 2, the pair of push buttons 19 are sandwiched from both sides with one finger and pressed from the outside of the cap 6 toward the inside of the cap 6. When the push button 19 is pressed, the elastic ring body 4 is elastically deformed between the inner cylinder body 13 and the outer cylinder body 11. The elastic ring body 4 that has been elastically deformed has its fitting piece 24 retracted from the annular projection 21 of the container body 2 and the fitting part is released. Simultaneously with the release, the elastic ring body 4 is pushed along the cone surface 8 together with the push button 19. Start to rise.

  When it starts to move up, the cap 6 starts to rise, the engagement piece 23 of the cap 6 elastically deforms, gets over the annular protrusion 21 of the container body 2 and the engagement portion is released. After the engagement portion is disengaged, the cap 6 is still raised and removed from the container body 2. When the finger is released from the push button 19 after the cap 6 is removed, the elastic ring body 4 is elastically restored and the push button 19 is restored to the position before the pressing operation.

  The container 1 with cap (Example container) of this embodiment, the comparison container 1 which removed only the support part 12 from the Example container as a comparative example, and the fitting piece 24 of the elastic ring body 4 is further removed from the comparison container 1 The comparison containers 2 were prepared, 30 mL of water was put inside each container, the caps were put down, and the containers were left to stand in a reduced pressure chamber, and the airtightness under reduced pressure was compared.

  As shown in Table 1, all of the comparative containers 2 leaked at -45 mmHg or higher, and the comparative containers 1 leaked water at -250 mmHg or higher, while the examples of the containers leaked even when they exceeded -500 mmHg. I did not. Thus, the comparative container 1 having the fitting piece 24 on the elastic ring body 4 is clearly superior in airtightness as compared with the comparative container 2 capped only by the locking part, but the support part 12 is added thereto. The example container was proved to be a container having a further improved airtightness than the comparative container 1.

  In the cap-equipped container 1 according to the present embodiment described above, the outer ring of the cylindrical body 3 is provided at a position where the lower end surface of the elastic ring body 4 comes into contact so as to support the elastic ring body 4. The cylindrical body portion 3 and the elastic ring body 4 of the top plate portion 5 can be tightly integrated in the cap 6 by the support portion 12 that connects the body 11 and the inner cylindrical body 13, and the elastic ring body 4 is not uniform. Even if a strong force is applied, the opening 10 can be hermetically sealed with the cap 6 without causing bending, and the hermeticity of the container body 2 can be improved.

  Therefore, the cap-equipped container 1 according to the present embodiment is configured so that the cap 6 is brought into contact with the container main body 2 due to an increase in internal pressure due to the volatile contents contained in the container main body 2 or an operation of lifting the cap-equipped container 1 with only the cap 6. Can be prevented from rising, thereby preventing the seal from being cut, and the airtightness inside the container body 2 can be always kept appropriate. Moreover, since the cap 6 can be completed only by attaching the top plate part 5 to the cylindrical trunk | drum 3 from upper direction, it can assemble easily and can improve productivity.

  Further, since the elastic ring body 4 is fixed to the top plate part 5 through the flexible piece 18 and is also supported by the support part 12, the push button is attached to the cap body part like the container with the cap of the prior application. It is not necessary to assemble the elastic ring body and the cap by passing through the provided through hole, or to push the push button more than the cap body part by the stroke for elastically deforming the elastic ring body. The periphery of the button 19 can be formed into a free shape that can be easily pressed with a finger, such as a notch or a relief.

  In the above-described embodiment, the case where the cone surface 8 constituting the lifting means is formed below the neck portion 7 is described as an example. However, the cone surface 8 is formed around the opening portion 10, and the engaging portion and the fitting portion are provided. You may make it form the cylinder surface equivalent to the neck part in which the cyclic | annular protrusion 21 to comprise is formed under the cone surface 8. FIG.

  In any of the cap-equipped containers 1 according to the present embodiment, the cap 6 can be attached and detached in the vertical direction, and the container body 2 can be opened and closed very easily.
