Description
Technical Field
The present invention relates to a slit valve-equipped cap including a slit valve formed with a slit at a top portion and made of an elastic material.
Background
Conventionally, a slit valve-equipped cap including a slit valve formed with a cross-shaped slit at the top and made of an elastic material has been known (see patent document 1).
The lid with the slit valve as described above is used by being attached to, for example, a mouth portion of a squeezable container, and when the container is squeezed downward from the mouth portion side to increase internal pressure, the content is ejected by pushing the slit open, and the slit is closed by relieving the force of squeezing the container. Thus, by increasing or decreasing the force for squeezing the container, an appropriate amount of the content can be discharged.

Problems to be solved by the invention
However, in patent document 1, the slit valve is attached to the cap body so that one of the cuts of the cross-shaped orthogonal slit coincides with the direction in which the container tilts when discharging the content, thereby improving the liquid separation when discharging the content.
However, in the lid with a slit valve proposed in patent document 1, since the content present at the valve tip portion is sucked into the container when the slit is closed, the liquid separation is good (see paragraph 0013 of patent document 1), but no research has been made for preventing the content from dropping from the valve peripheral edge. The dropped contents are not sucked into the container and remain around the valve rim and the slit, which is not hygienic and is not preferable in terms of appearance.
In addition, in the slit valve cap of patent document 1, not only is it troublesome and time-consuming to align the slit, but also the user does not always tilt the container in a constant direction, and therefore the intended effect cannot be expected. Further, it is proposed to provide a mark indicating a direction in which the container is tilted (see paragraph 0018 of patent document 1), but this is required to depend on the user's recognition.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cap with a slit valve, which can recover a content remaining in a valve into a container regardless of a position of a slit of the slit without dropping the content from a peripheral edge of the valve to the outside when the content is discharged.
Means for solving the problems
The slit valve-equipped cap of the present invention comprises: a cap body to which a slit valve formed with a slit at a top thereof and made of an elastic material is attached; and an upper cover that is attachable to and detachable from the cover main body, wherein the cover main body includes: an injection port part that opens above the slit valve and stands in a cylindrical shape; a rim portion that extends outward from a base end of the spout portion and covers a peripheral side of a top portion of the slit valve; and a side wall portion that hangs down along an outer peripheral edge of the rim portion to surround a side surface of the slit valve.
Effects of the invention
According to the present invention, when the content is discharged, the content discharged from the slit valve can be left in the spout portion and can be discharged from the spout portion. At this time, since the peripheral edge of the top portion of the slit valve is covered with the rim portion, the content does not drip from the peripheral edge of the valve to the outside. Further, the content remaining in the spout portion after the pouring can be easily introduced through the slit of the slit valve, and can be recovered into the container regardless of the position of the cut of the slit.

Detailed Description
Hereinafter, an embodiment of a slit valve-equipped cover according to the present invention will be described with reference to the drawings.
The cap 1 of the present embodiment is made of synthetic resin, and is an example in which the present invention is applied to a so-called hinge cap in which a cap body 2 and an upper cap 3 that is detachable from the cap body 2 are coupled by a hinge 4, and is used by being attached to a mouth portion 10 of a squeezable container.
Here, fig. 1 is a plan view showing a state where the upper cover 3 is fitted to the cover main body 2, fig. 2 is a sectional view taken along line a-a of fig. 1, and directions of the respective members constituting the cover 1 in the vertical, horizontal, and vertical directions are defined in the state shown in fig. 2.
Fig. 3 is a plan view showing a state where the upper lid 3 is detached from the lid main body 2, and fig. 4 is a sectional view B-B of fig. 3.
In the present embodiment, the cover main body 2 includes: an outer tube portion 21 hanging down along the outer peripheral edge; and an inner tube portion 22 that hangs down concentrically inside the outer tube portion 21. When the cap 1 is attached to the mouth portion 10 of the container, the fitting portion 21a formed on the inner peripheral surface on the lower end side of the outer tube portion 21 is fitted to the fitting portion 10a formed on the outer peripheral surface side of the mouth portion 10, and the inner tube portion 22 is brought into liquid-tight close contact with the inner peripheral surface of the mouth portion 10.
In this way, the cap 1 is attached to the mouth 10 of the container in a liquid-tight manner by a plug, but the means for attaching the cap 1 is not limited thereto as long as the cap 1 can be attached to the mouth 10 of the container in a liquid-tight manner.
Further, a slit valve 5 is attached to the cap body 2. The slit valve 5 has, for example: a top portion 5a formed with a slit S cut in a cross shape or the like; a cylindrical portion 5b hanging down along the outer peripheral edge of the top portion 5 a; and a flange portion 5c formed to protrude outward on the lower end side of the cylindrical portion 5 b. The slit valve 5 as described above is made of an elastic material such as silicone rubber, and the slit S formed in the top portion 5a is formed to be opened and closed by elastic deformation.
Fig. 5 is a perspective view of the slit valve 5 as viewed from obliquely above.
The cap body 2 has a spout portion 25 that opens above the slit valve 5 and stands in a cylindrical shape. The spout portion 25 is a portion serving as a spout for the content discharged from the slit S of the slit valve 5, and is formed such that the inner diameter of the spout portion 25 is smaller than the outer diameter of the top portion 5a of the slit valve 5. In order to achieve good liquid separation when the content is dispensed and to further suppress dripping of the liquid and remaining of the content on the distal end side of the spout portion 25 when the container is returned to the upright state, it is preferable that the inner peripheral surface on the distal end side of the spout portion 25 is inclined so as to expand in diameter toward the distal end and the distal end of the spout portion 25 is formed so as to be curved so as to be warped outward as shown in the drawing.
Further, the cap body 2 includes: a rim portion 24 that extends outward from the base end of the spout portion 25 so as to cover the peripheral side of the top portion 5a of the slit valve 5; and a side wall portion 23 that hangs down along the outer periphery of the rim portion 24 so as to surround the side surface of the slit valve 5, and the slit valve 5 is inserted into a recessed portion defined by these portions. Further, a locking step portion 23a for locking the flange portion 5c of the slit valve 5 is provided on the lower end side of the side wall portion 23, and a protrusion 23b for fitting into the peripheral edge of the annular pressing member 6 is provided at a position close to the locking step portion 23 a.
Thus, in the slit valve 5, the flange portion 5c is sandwiched between the locking step portion 23a and the pressing member 6 and attached to the cap body 2, but the attachment mechanism of the slit valve 5 is not limited to this as long as the slit valve 5 is attached so as not to easily fall off from the recessed portion defined by the side wall portion 23 and the rim portion 24.
A sealing body 7 is attached to the upper cover 3 that is detachable from the cover main body 2, and the sealing body 7 seals the spout portion 25 to prevent the content from leaking when the upper cover 3 is fitted to the cover main body 2. The sealing body 7 has: a seal portion 71 inserted into the spout portion 25; and an outer peripheral fitting portion 72 fitted to the fitting cylinder portion 32 hanging down in a cylindrical shape from the top surface portion 31 of the upper lid 3.
Fig. 6 is a perspective view of the sealing body 7 as viewed obliquely from below.
The outer peripheral fitting portion 72 of the seal body 7 has an outer tube portion 73 and an inner tube portion 74, and lower ends thereof are connected by a bottom plate portion 75, and formed in a U-shape in vertical cross section. Further, the outer peripheral fitting portion 72 of the seal body 7 is fitted into the fitting cylinder portion 32 of the upper cover 3 with a clearance by the fitting convex portion 73a formed on the outer peripheral surface on the upper end side of the outer cylinder portion 73 and the fitting convex portion 32a formed on the inner peripheral surface on the lower end side of the fitting cylinder portion 32, and a play is provided between the fitting convex portion 73a of the outer cylinder portion 73 and the fitting convex portion 32a of the fitting cylinder portion 32. In this way, when an impact is applied by dropping the container or the like in a state where the upper lid 3 is fitted to the lid main body 2, the impact, particularly, a vertical impact can be absorbed.
Further, when the seal portion 71 of the seal body 7 is inserted into the spout portion 25, the seal portion 71 is brought into liquid-tight contact with the inner peripheral surface of the spout portion 25, and the dimensions and the like thereof are appropriately set so that the spout portion 25 can be sealed. In this case, in order to improve the adhesion between the inner peripheral surface of the outlet port portion 25 and the seal portion 71, it is also effective to form a concave portion 25a on the inner peripheral surface on the proximal end side of the outlet port portion 25 and to form a bulging portion 71a to be engaged with the concave portion 25a on the side surface of the seal portion 71. Further, as described above, when the tip of the spout portion 25 is formed to be curved so as to be warped outward, engagement from the outer peripheral surface side of the spout portion 25 is difficult, and therefore, the above configuration is particularly effective in such a case.
When the seal portion 71 of the seal body 7 is inserted into the spout portion 25, the lower end edge of the outer peripheral fitting portion 72 of the seal body 7 engages with the engagement stepped portion 24a formed on the outer peripheral edge of the rim portion 24 of the cover main body 2, and the spout portion 25 into which the seal portion 71 is inserted is pressed, whereby the adhesion between the inner peripheral surface of the spout portion 25 and the seal portion 71 can be improved. Further, since the outer peripheral fitting portion 72 formed in a U-shape in vertical section functions as a buffer portion, when an impact is applied by dropping or the like of the container in a state where the upper lid 3 is fitted to the lid main body 2, the impact, particularly, a lateral impact can be absorbed.
Thus, in the present embodiment, in combination with the case where the outer peripheral fitting portion 72 of the seal body 7 formed in a U-shape in vertical section is fitted to the fitting cylindrical portion 32 of the upper cover 3 in a clearance fitting manner, the spout portion 25 can be more reliably sealed. In particular, in the present embodiment, since the spout portion 25 is sealed without the tip end side of the spout portion 25 coming into contact with the seal body 7, the spout portion 25 can be reliably sealed even if the tip end of the spout portion 25 is formed to be curved so as to be warped outward.
Here, in fig. 2, the portions of the members shown in the figure that overlap each other are actually elastically deformed to interact with the pressing force. For example, fig. 7 is an enlarged view of a portion surrounded by a chain line in fig. 2, and the seal portion 71 of the seal body 7 and the spout portion 25 are brought into close contact with each other by a force indicated by an arrow in fig. 7. Further, a force indicated by an arrow in fig. 7 acts on the outer peripheral fitting portion 72 (outer tube portion 73) of the seal body 7, and the top surface portion 31 of the upper cover 3 is pressed down, so that the spout portion 25 can be pressed in a state where the outer peripheral fitting portion 72 is biased.
In the present embodiment, a guide tube 33 is provided so as to hang down from the top surface portion 31 of the upper lid 3, and the tip end of the guide tube 33 is fitted between the outer standing portion 2a and the inner standing portion 2b standing from the lid main body 2. By such fitting, when an impact is applied by dropping the container or the like, the impact, particularly a lateral impact, can be absorbed, and the spout portion 25 can be sealed more reliably.
The outer standing portion 2a and the inner standing portion 2b of the cap body 2 may be continuously formed in a ring shape, or may be partially cut off. As shown in the drawing, it is preferable that the outer standing part 2a is formed so that the inner peripheral surface thereof is expanded in diameter toward the distal end, and the inner standing part 2b is formed as an inclined annular wall so that the outer peripheral surface thereof is reduced in diameter toward the distal end. When the upper lid 3 is fitted to the lid main body 2 in this manner, the tip end of the guide tube 33 is guided so as to be in contact with the inner peripheral surface of the outer standing portion 2a or the outer peripheral surface of the inner standing portion 2b, and is fitted between the outer standing portion 2a and the inner standing portion 2 b. As a result, the position of the seal portion 71 of the seal body 7 and the spout portion 25 can be prevented from being displaced, and the seal portion 71 can be more reliably inserted into the spout portion 25.
In addition, when the upper lid 3 is fitted to the lid main body 2, in the present embodiment, the outer standing portion 2a is formed on the outer peripheral edge side of the lid main body 2, and the positions of the inner standing portion 2b and the guide cylinder 33 are appropriately adjusted so that the fitting portion 30a formed on the inner peripheral surface on the lower end side of the tube portion 30 that hangs down from the outer peripheral edge of the top surface portion 31 of the upper lid 3 is fitted to the upper end edge of the outer standing portion 2 a.
Next, an operation of pouring out the content from the container to which the cap 1 of the present embodiment is attached will be described.
First, the upper lid 3 is detached from the lid main body 2, the sealing of the spout portion 25 by the sealing portion 71 of the seal body 7 is released, and the container is pressed with the spout portion 25 facing downward. Thereby, the pressure in the container is increased, the content is discharged so as to push open the slit S of the slit valve 5, and the discharged content is discharged from the spout portion 25. After a proper amount of the contents is discharged, the container is returned to the upright state and the force of pressing is relieved to restore the container. As the pressure in the container decreases, the content remaining in the spout portion 25 is drawn into the container through the slit S, and then the slit S is closed to complete the dispensing operation.
As described above, according to the present embodiment, when the content is discharged, the content discharged from the slit valve 5 can be left in the spout portion 25 and can be discharged from the spout portion 25. At this time, since the peripheral edge of the top portion 5a of the slit valve 5 is covered with the rim portion 24 of the cap body 2, the content does not drip from the peripheral edge of the valve to the outside. The content remaining in the spout portion 25 after the pouring, that is, the content remaining on the slit valve 5 is easily introduced from the slit S of the slit valve 5, and can be collected into the container regardless of the position of the cut of the slit S.
In the present embodiment, the inner peripheral surface of the tip end side of the spout portion 25 is inclined so as to be expanded in diameter toward the tip end, and the tip end of the spout portion 25 is formed to be curved so as to be warped outward. As a result, as described above, liquid separation during discharge of the content is improved, and liquid dripping is more favorably suppressed, and the content remaining on the distal end side of the spout portion 25 after liquid separation flows down into the spout portion 25 so as to slide on the inner peripheral surface on the distal end side of the spout portion 25 when the container is returned to the upright state. Therefore, the content can be effectively suppressed from adhering to and remaining on the distal end side of the spout portion 25.
When the content remaining in the spout portion 25 is introduced into the container, the amount that can be introduced depends on the volume change when the container is squeezed. Therefore, assuming a general volume change, it is preferable that the volume of the space in the spout portion 25 formed above the slit valve 5 is smaller than the change amount. In particular, in the present embodiment, the cap body 2 has the rim portion 24 covering the peripheral side of the top portion 5a of the slit valve 5, and the inner diameter of the spout portion 25 formed to rise in a cylindrical shape along the inner peripheral edge of the rim portion 24 is formed smaller than the outer diameter of the top portion 5a of the slit valve 5, so that it is easy to design that the volume of the space in the spout portion 25 formed above the slit valve 5 is reduced.
Although the present invention has been described above by showing preferred embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention.
For example, in the above-described embodiment, the lid main body 2 and the upper lid 3 are coupled by the hinge 4, but the lid main body 2 and the upper lid 3 may be separately formed, and the upper lid 3 may be attached to and detached from the lid main body 2 by screwing.
The slit valve-equipped cap of the present invention can be used by being attached to the mouth of a container containing, as contents, seasonings such as oils, soy sauce, and seasoning, and liquids such as detergents and cosmetics.
The contents of the documents described in the present specification and the contents of the japanese application specification that is the basis of the priority of the paris convention of the present application are all incorporated herein by reference.
