Description

The present invention relates to a discharge container.

For example, when a discharge container is used for business purposes such as a hotel, it is desirable to take measures to prevent mischief such as foreign matter being mixed into the container.
As a discharge container that meets these demands, it consists of a container body that erects the mouth and neck, a discharge pump attached to the mouth and neck, and a covering.
The discharge pump projects an inward flange from the upper end of the mounting cylinder screwed to the outer surface of the mouth neck of the container body, and sandwiches the flange at the upper end of the cylinder between the inward flange and the mouth neck. Then, the pump is vertically hung in the container, and the lower half of the operating member is hung in the cylinder so as to be able to move up and down and in an upwardly urged state.
The cover ring is fitted to the outer surface of the mounting cylinder so as to be able to move up and down.
A lock mechanism is provided to lock the cover ring on the mounting cylinder at the upper limit position of the cover ring with respect to the mounting cylinder and release the lock at the lower limit position.
When the cover ring in the upper limit position is rotated, the mounting cylinder can be rotated together to separate it from the mouth and neck, and when the cover ring in the lower limit position is rotated, the cover ring slips with respect to the mounting cylinder. , A structure is known in which the mounting cylinder cannot be screwed off (Patent Document 1).

JP 2001-240110

In the discharge container of Patent Document 1, the cover ring is set at the lower limit position with respect to the mouth and neck and equipped in a hotel guest room or the like, and the discharge pump cannot be removed even if the cover ring is rotated in this state. When the employee refills the contents, the cover ring is moved to the upper limit position and the discharge pump is removed from the container body so that a new container body can be filled.
However, for example, when the content is a mouthwash or the like, it is not refilled or replaced, so once the mounting cylinder of the discharge pump is tightened and screwed to the mouth and neck of the container body, it is used by the user. Later, it is desired that the discharge pump cannot be removed again.
However, when the mounting cylinder is tightened to the mouth and neck, the tightening torque of the mounting cylinder may be lower than the specified value in rare cases, so it is desirable to leave room for retightening in preparation for such a situation.
Further, when the discharge container is used at home, there is no concern about the mischief, so that the container body and the discharge pump can be provided in a form in which the covering is omitted without significantly changing the conventional configuration. It is also convenient in terms of cost.

A first object of the present invention is to provide a discharge container in which the peripheral surface of the mounting member of the discharge pump mounted on the container body is covered with a cover ring to prevent unauthorized removal of the discharge pump and the covered state cannot be released. It is to be.
A second object of the present invention is to provide a discharge container in which the cover ring is vertically locked at a position covering the peripheral surface of the mounting member, and this locked state can be realized by a simple operation.
A third object of the present invention is to provide a discharge container capable of achieving each of the above objects by applying a covering to a known structure of a conventional discharge pump.

The first means is a container body 2 in which a mouth and neck tube 8 is erected from the body 4 to the tip tube 14 having a threaded portion 16 formed on the outer surface via the base tube 10.
A tubular mounting member 22 screwed onto the outer surface of the tip cylinder portion 14 and
The upper part of the cylinder 28 inserted into the container body 2 is detachably attached to the mouth and neck cylinder 8 via the mounting member, and the lower half of the operating member 34 having the discharge head 38 is attached to the cylinder 28. It is fitted and inserted so as to be able to move up and down in an upwardly urged state, and the liquid in the container body 2 can be sucked up into the cylinder 28 by raising and lowering the operating member, and can be discharged from the inside of the cylinder 28 from the discharge head 38. Cylinder discharge pump body 26 and
A cover ring 40 provided around the base cylinder portion 10 is provided.
The discharge pump main body 26 includes an annular retaining member 32 attached to the upper end portion 28a of the cylinder 28 as a means for preventing the lower portion of the operating member 34 from coming out of the cylinder 28, and the retaining member 32 and the retaining member 32. A gap g is formed between the mounting member 22 and the mounting member 22.
The cover ring 40 can be moved from a lower position surrounding the base cylinder portion 10 to an upper position covering substantially the entire outer circumference of the mounting member 22, and the cover ring 40 moved to the upper position is a mounting member. A locking means E for locking in the vertical direction is provided so as not to separate from the peripheral surface of 22.
The locking means E is formed by connecting the rigid locking piece 54 located outside the mounting member 22 when viewed from above to the covering 40 via a deformable bearing 50.
After covering 40 is moved to the upper position, it is configured as rigid locking pieces 54 is inserted into the gap g by inwardly pushing.

In this means, as shown in FIG. 1, a container body 2 is provided from the body portion 4 by erecting a mouth and neck cylinder 8 which is continuous from the base cylinder portion 10 to the front cylinder portion 14, and is attached to the front cylinder portion 14. The cover ring 40 provided around the base cylinder portion 10 with the member 22 screwed is moved from the lower position shown in the figure to the upper position covering substantially the entire outer circumference of the mounting member 22 as shown in FIG. I am trying to be able to. In this state, since the cover ring 40 covers substantially the entire outer circumference of the mounting member 22, the mounting member 22 cannot be turned by hand, and when the cover ring 40 is rotated, it idles with respect to the mounting member 22. Therefore, the mounting member 22 cannot be rotated. Therefore, the mounting member 22 cannot be screwed off from the mouth and neck cylinder 8 to remove the discharge pump 20, and foreign matter cannot be mixed into the container body. A locking means E is provided which connects the rigid locking piece 54 to the cover ring 40 via a deformable bearing 50. Then, the rigid locking piece 54 is inserted into the gap g existing between the mounting member 22 and the retaining member 32 by inward pushing. This prevents the cover ring 40 from coming off the peripheral surface of the mounting member 22.

The "covering" has a role of making it impossible to screw off the mounting member 22 by covering substantially the entire outer circumference of the mounting member 22 and idling with respect to the mounting member 22 while moving to the upper position.
"Covering substantially the entire outer circumference of the mounting member 22" means covering the outer circumference of the mounting member 22 to the extent that it cannot be directly gripped and rotated. By providing the notch 44 described later, the outer circumference of the outer circumference is covered. It does not matter if a part is exposed.
The "rigid locking piece" is inserted into the gap g between the mounting member 22 and the retaining member 32 , and is brought into contact with the discharge pump main body 26 when the cover ring 40 is pulled up. Any structure may be used as long as it has a rigidity sufficient to resist the pulling of the 40 by contacting the mounting member 22.
The "support body" supports the rigid locking piece 54 and at the same time deforms so that the rigid locking piece can enter the gap from a standby position away from the gap g.
The deformation is preferably a deformation that does not return to the original state (plastic deformation), but is not necessarily limited to this. This is because a means (stopper or the like) for preventing the bearing from returning to its original shape may be separately provided.

The second means includes the first means, and the support 50 is composed of a pair of support arms 52 extending from both sides of the rigid locking piece 54 and continuous with the cover ring 40, and the tips of these support arms. By connecting the portions to two connection points J, J which are separated from each other of the cover ring 40, the rigid locking piece 54 can be seen from above from a standby position set on the outside of the mounting member 22. It is formed so that it can be inverted to the lock position where it rushes into the gap.

In this means, the bearing body 50 is formed by a pair of support arms 52 extending from both sides of the rigid support piece 54, and is provided so as to reverse from the state of FIG. 2 to the state of FIG. 4 by pushing inward. With this configuration, the covering 40 can be locked by simply pushing the locking means E inward, which is convenient.

The third means has a second means, and at least one thin-walled portion 53 is formed on the support arm 52.

In this means, as shown in FIG. 2, it is proposed to form a thin portion 53 on the support arm 52. This makes it easier to deform the support arm 52, and the above-mentioned reversal can be caused with a slight force. In the illustrated example, two thin-walled portions are provided, but at least one thin-walled portion is sufficient.

The fourth means has a second means or a third means, and forms a notch 44 in a part of the upper end of the covering 40 in the circumferential direction, and both sides of the notch 44 in the circumferential direction. Support arms 52 extending from both sides of the rigid locking piece 54 are connected between the portions.

In this means, as shown in FIGS. 2 and 3, a notch 44 is formed in a part of the upper end of the cover ring 40 in the circumferential direction, and a rigid locking piece is formed between both ends of the notch in the circumferential direction. Support arms 52 extending from both sides of 54 are formed. According to this configuration, a mechanism for locking the cover ring 40 is provided on the cover ring itself, and it is not necessary to form a special mechanism on the side of the discharge pump main body 26. Therefore, it is normal for a conventional discharge pump. The structure can be used as it is, which is economical. This is because, for example, it is advantageous to develop manufacturing activities of both or one of a discharge container with a covering and a discharge container without a covering according to future market trends.

The fifth means has any of the first to fourth means, and the cover ring 40 is provided with at least a pair of locking means E arranged at positions facing each other. ..

In this means, for example, as shown in FIGS. 2 and 6, the cover ring 40 is provided with at least a pair of locking means E arranged at positions facing each other. The cover ring 40 can be locked more reliably by the pair of locking means arranged at these facing positions. Any number of pairs of such locking means may be provided. In the illustrated example, a pair of left and right locking means is disclosed, but a pair of left and right locking means and a pair of front and rear locking means may be provided.

According to the invention according to the first means, the mounting member 22 is moved from the lower position surrounding the base cylinder portion 10 of the mouth and neck cylinder 8 to the upper position covering the entire outer surface of the mounting member 22. In a discharge container in which the mounting member 22 is screwed off from the mouth and cervical cylinder 8, the cover ring 40 is connected to the cover ring 40 via a support body 50 in a state of being in an upper position. By pushing the rigid locking piece 54 inward, the rigid locking piece 54 is inserted into the gap g between the mounting member 22 and the retaining member 32 , so that the cover ring 40 is separated from the mounting member 22. It is possible to prevent mischief such as mixing foreign substances.
According to the invention according to the second means, the rigid locking piece 54 can be inverted from a standby position set on the outside of the mounting member 22 when viewed from above to a lock position that plunges into the gap. Since it is provided so that it can be operated, it is easy to operate.
According to the invention according to the third means, since at least one thin-walled portion 53 is formed on the support arm 52, the force required to push the rigid locking piece 54 inward and reverse it is reduced.
According to the invention according to the fourth means, a notch 44 is formed in a part of the upper end of the cover ring 40 in the circumferential direction, and a rigid locking piece 54 is formed between both side portions of the notch 44 in the circumferential direction. Since the support arms 52 extending from both sides of the above are connected, the reversing function can be realized with a simple configuration.
According to the invention according to the fifth means, since the cover ring 40 is provided with at least a pair of locking means E arranged at positions facing each other, the locked state of the cover ring 40 is more reliably maintained. can do.

It is explanatory drawing which shows the operation of the main member of FIG.

1 to 7 show a discharge container according to the first embodiment of the present invention. This discharge container is formed of a container body 2, a discharge pump 20, and a covering 40. Each of these members can be made of synthetic resin or metal.

The container body 2 stands up the mouth and neck tube 8 from the body 4 via the shoulder 6. The mouth and neck cylinder 8 has a base cylinder portion 10 for setting the cover ring 40 described later in the initial state shown in FIG. 1, and a tip cylinder portion 14 for screwing the mounting cylinder 24 described later.
The base cylinder portion 10 has a larger diameter and is formed longer than the tip cylinder portion 14. In the illustrated example, the shoulder portion 6 is continuously provided from the upper end to the tapered tubular portion 10b having a small diameter at the upper end via the vertical tubular portion 10a, and the outer rib 12 is provided around the lower end of the vertical tubular portion 10a. The vertical cylinder portion 10a is formed to have substantially the same outer diameter as the mounting cylinder 24 described later, except for a portion where the outer rib 12 is provided.
A screw portion 16 is formed on the outer surface of the tip cylinder portion 14.

The discharge pump 20 has a conventionally known configuration, and in the illustrated example, the discharge pump 20 is composed of a mounting member 22 and a discharge pump main body 26.
The mounting member 22 has a mounting cylinder 24 screwed onto the outer surface of the tip cylinder portion 14 of the mouth neck cylinder 8, and an inward flange 25 projects from the upper end of the mounting cylinder 24.
The discharge pump main body 26 is composed of a cylinder 28, a retaining member 32, and an operating member 34, and these structures can be appropriately changed.
The cylinder 28 has a collar portion 30 that projects outward from the upper end of the cylinder peripheral wall. The cylinder 28 is vertically installed in the container body 2 by sandwiching the flange portion 30 between the mouth and neck cylinder 8 and the inward flange 25. The cylinder peripheral wall of the illustrated example has an extension wall portion 28a extending above the collar portion. Further, a suction pipe 29 hangs down from the lower part of the cylinder 28 toward the bottom side of the container body 2. A first check valve V1 is formed in the lower part of the cylinder 28.
The retaining member 32 is an annular member attached to the upper part of the cylinder 28 in order to prevent the operating member 34 described later from coming off. As a preferred example, in the retaining member 32, the inner cylinder portion 32b and the outer cylinder portion 32c are vertically hung from the back surface of the top wall 32a in a double tubular shape, and the inner cylinder portion 32b and the outer cylinder portion 32c are formed. The extension wall portion 28a is sandwiched between them, and the top wall 32a is further extended to the outside, and the outer peripheral wall 32d (arranged at intervals outside the outer cylinder portion 32c) from the outer end of the top wall 32a. Is hanging. Further, ribs that mesh with each other are provided on the inner surface of the outer cylinder portion 32c and the outer surface of the extension wall portion 28a of the illustrated example to be fitted. However, these structures can be changed as appropriate. A gap g exists between the lower end surface of the outer peripheral wall 32d and the upper surface of the inward flange 25.
The operating member 34 is inserted into the cylinder 28 so as to be able to move up and down in an upwardly biased state, and forms a stem 37 that passes through the inside of the retaining member 32 from the inside of the cylinder 28 and is discharged to the upper end of the stem. A head 38 is attached. In the illustrated example, the upper part of the piston guide 35 is fitted to the lower part of the stem 37, and between the outward flange-shaped valve seat portion 35a attached to the lower end of the piston guide 35 and the lower end of the stem 37. A tubular piston 36 that is in sliding contact with the inner surface of the cylinder 28 is attached so as to be able to move up and down, and a second check valve V2 is formed between the tubular piston 36 and the valve seat portion. A coil spring C is interposed between the valve seat portion and the lower portion of the cylinder 28. With such a configuration, when the operating member 34 is moved up and down with respect to the cylinder 28, the liquid is sucked into the cylinder 28 from the inside of the container body 2 via the first check valve V1 and is a second check valve. It is discharged to the outside from the discharge nozzle 38a via V2.
Further, in the illustrated example, a mounting cylinder portion 38b hanging from the discharge head 38 is fitted on the upper outer surface of the stem 37, and a screw line 39 is formed on the outer surface of the mounting cylinder portion 38b. In the state of FIG. 1, the operating member 34 is screwed to the inner cylinder of the retaining member 32. However, these structures can be changed as appropriate.

The cover ring 40 surrounds the base cylinder portion 10 of the mouth and neck cylinder 8 at the lower position shown in FIG. 1, and is provided so as to be movable from this lower position to the upper position shown in FIG.
The cylinder wall 42 of the cover ring 40 has a cylinder length capable of covering substantially the entire outer circumference of the mounting member 22.
In the illustrated example, an engaging protrusion 42a is attached to the inner surface of the lower end of the cylinder wall 42. The engaging protrusion 42a is locked to the upper surface side of the outer rib 12 in the state of FIG. 1, and the engaging protrusion 42a and the outer rib 12 form a temporary fixing means T for the cover ring 40. .. In this temporarily fastened state, the cover ring 40 is below the mounting member 22, and is formed so as not to interfere with the screwing or unscrewing work of the mounting member 22 to the mouth and neck cylinder 8.
When assembling the container of the present application, as shown in FIG. 3, the cover ring 40 is temporarily fastened around the base cylinder portion 10 of the mouth and neck cylinder 8 of the container body 2 in advance, and the container body 2 is in this state. It is advisable to fill the contents. Next, when the mounting cylinder 24 of the discharge pump 20 is inserted into the tip cylinder portion 14 of the mouth neck cylinder 8, the configuration shown in FIG. 1 is obtained.

The cover ring 40 is provided with at least one locking means E. The locking means E has a function of locking the cover ring 40 moved to the upper position so as not to move in the vertical direction, and in a preferred illustrated example, a plurality of locking means E separated from each other in the circumferential direction of the cover ring 40. Locking means E is provided. The cover ring 40 can be molded in the form shown in FIG.

As shown in FIG. 2, each locking means E is formed by a rigid locking piece 54 and a bearing body 50 that connects and supports the rigid locking piece 54 to the cover ring 40. These members can be integrally molded together with the cover ring 40.
"""
In a preferred illustrated example, the rigid locking piece 54 is formed as a horizontal flat plate as shown in FIG. As a result, the present invention can be applied as long as there is a small gap g between the discharge pump main body 26 and the mounting member 22 so that the flat plate-shaped rigid locking piece 54 can be inserted. That is, the range of discharge pumps to which the present invention can be applied is expanded, and versatility is enhanced.
This is so that even if the gap g between the outer peripheral wall 32d and the inward flange 25 of the retaining member 32 is relatively narrow, it can be inserted. As shown in FIG. 2, the planar shape of the shown rigid locking piece 54 is substantially quadrangular, but the shape can be appropriately deformed. A recess 54a is formed on one side of the quadrangle near the cover ring 40.
It is preferable that the bearing body 50 is deformably provided so that the rigid locking piece 54 is inserted into the gap g by inward pushing, and is formed so that this deformed state is maintained.
The bearing body 50 of the present embodiment is composed of a pair of support arms 52 protruding from both sides of the rigid locking piece 54, and both ends of these support arms 52 are appropriately separated from each other at two connection points J, J. It is configured to be connected to and inverted from the state of FIG. 2 to the state of FIG. As a result, the rigid locking piece 54 moves from the standby position away from the gap g to the lock position where it plunges into the gap g.
In the illustrated example, a concave notch 44 wide and shallow in the circumferential direction is formed at the upper end of the cover ring 40, and the upper ends of both side portions 46 in the circumferential direction of the notch 44 are connection points J and J. Each end of the support arm 52 is integrally connected to the support arm 52. However, this configuration can be changed as appropriate, and for example, connecting protrusions may be projected upward from two points in the circumferential direction of the upper end of the cover ring, and these protrusions may be used as connection points.
As shown in FIG. 2, each support arm 52 is formed in an arc shape along the contour of the cover ring 40 when viewed from above, and a thin portion 53 is formed on the support arm 52. In a preferred illustrated example, the first thin-walled portion 53a and the second thin-walled portion 53b are provided on both sides of the support arm 52 in the circumferential direction. As a result, the above-mentioned support arm 52 can be inverted with a small force, so that the operation is easy.
In the configuration of this example, the bearing 50 is inverted by locally bending a part of the support arm 52 in the longitudinal direction, so that the inversion operation is irreversible. Therefore, the locked state of the rigid locking piece 54 in the gap g is surely maintained.
In the present embodiment, since a mechanism for locking the rigid locking piece 54 to the gap g of the discharge pump 20 is provided on the side of the cover ring 40, it is necessary to make the conventional discharge pump 20 a special specification. Absent. Therefore, the conventional discharge pump configuration can be used as it is, which is economical. This is because we are developing the manufacture and sale of conventional containers with discharge pumps that do not have coverings for general households without worrying about mischief, and when demand arises for applications such as hotels, the required number of coverings This is because it can be applied to a container with a conventional pump, and wasteful inventory can be saved.
6 and 7 are modified examples of the cover ring 40, FIG. 6 is a plan view of the cover ring 40 provided with four locking means E, and FIG. 7 shows each locking means inward. The figure of the pushed state is shown respectively.

In the above configuration, the state of FIG. 1 is an aspect at the distribution stage as a commercial product, and since the mounting cylinder 24 is not yet covered with the covering 40, the mounting cylinder 24 can be operated. In this state, the discharge head 38 is rotated with respect to the retaining member 32, and the discharge head 38 is pulled up together with the stem 37 as shown in FIG. In the initial state, since air is contained inside the cylinder 28, the liquid can be discharged by raising and lowering the operating member 34 several times to exhaust the air (initial priming).
Next, when the cover ring 40 is pulled up to an upward position as shown in FIG. 5, and then the rigid locking piece 54 is pushed inward, the support arm 52 bends at the thin portion 53, and the entire support body 50 moves inward. As a result, the rigid locking piece 54 enters the gap g between the outer peripheral wall 32d of the retaining member 32 and the mounting member 22, and the cover ring 40 is locked in the vertical direction. That is, if the cover ring 40 is to be pulled up further in this state, the rigid locking piece 54 hits the retaining member 32, and if the cover ring 40 is to be pulled down, the rigid locking piece 54 hits the mounting member 22. The ring 40 cannot be detached from the mounting cylinder 24.
In this state, even if the cover ring 40 is rotated, the cover ring 40 idles with respect to the mounting cylinder 24, so that the mounting cylinder 24 cannot be screwed off from the mouth and neck cylinder 8. Further, since the cover ring 40 covers substantially the entire outer circumference of the mounting member 22, the mounting cylinder 24 cannot be directly rotated by hand. Therefore, it is possible to completely prevent mischief in which foreign matter is mixed into the container body.
The reason for raising the cover ring 40 after raising the discharge head 38 will be described. If the cover ring 40 is set around the mounting cylinder 24 before raising the discharge head 38, it is mounted when the tightening torque is rarely lower than the specified value in the work of tightening the mounting cylinder 24 with respect to the mouth and neck cylinder 8. The cylinder 24 cannot be further tightened, which may make it unusable. In order to avoid such a situation and leave room for additional tightening, the discharge head 38 is raised first.
