Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a dispenser that is attached to the mouth of a container and that drains the liquid in the container, and in particular, a dispenser that is not equipped with a pump mechanism and that drains the liquid by squeezing the container itself. This invention relates to a squeeze-type dispenser that pressurizes and releases liquid.

[Conventional technology]

This type of dispenser has a cap attached to the mouth of the container and a head rotatably attached to the cap. The head of the dispenser allows liquid to flow out and
When not in use, it must be configured to prevent liquid from flowing out and ensure a liquid-tight seal.
Therefore, for example, by providing a side hole in the upper end of the cap, and providing a liquid outflow path that can be aligned with the side hole in the head, and aligning the liquid outflow path with the side hole, the liquid can flow out. The structure is such that liquid tightness can be obtained by making them non-aligned.

[Problem that the invention seeks to solve]

Generally, this type of dispenser is shipped and sold attached to a container containing a liquid. However, careless squeezing may cause the liquid to spill out accidentally and cause an accident, so this type of dispenser should not be used unless it is in use.
It is required to be maintained in a liquid tight position (sealed position). In the known configuration, the head is rotated to a position where the liquid outflow path is not aligned with the side hole, and liquid tightness is achieved by surface contact between the inner surface of the head and the outer surface of the cap. However, the head is loosely fitted into the cap to allow rotation of the head. Therefore, it is difficult to obtain sufficient liquid tightness through surface contact. Also, once the dispenser is used, liquid remains in the liquid outlet path of the head. This residual liquid may drip from the liquid outflow path and stain the surrounding area, or may solidify and block the liquid outflow path. However, a squeeze dispenser type that prevents leakage of residual liquid and ensures liquid tightness except when in use has not yet been provided.

[Means for solving problems]

The object of the present invention is to provide a squeeze dispenser type that prevents residual liquid from leaking and ensures liquid tightness even when not in use.

To achieve this objective, according to the invention:
It is attached to the mouth of a container in which a liquid is stored, and has a cap to which a suction pipe can be attached inside, and a beak on the side of the top with a liquid outflow path that can communicate with the suction pipe. When the head is reciprocally attached to the cap so that the outflow path can communicate with the suction pipe, and when the head is located in a position where the liquid outflow path does not communicate with the suction pipe, there is a gap between the top of the head and the upper end of the cap. and a seal cap rotatably molded integrally with the head via a hinge and closing the opening of the liquid outflow path when rotated.

[Effect]

In such a configuration, a liquid-tight position is obtained in the depressed position (inward position) of the head, where the top of the head is pressed against the upper end of the cap. Therefore, liquid tightness is independent of the gap existing between the head and the cap, and reliable liquid tightness can be obtained. Furthermore, since the opening of the liquid outflow path is closed by the seal cap, leakage of residual liquid in the liquid outflow path is also prevented.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, a dispenser 10 according to the present invention includes a cap 16 attached to a mouth portion 14 of a squeezable container 12 containing a liquid;
The cap is equipped with a head 18 which is attached to the cap so that it can reciprocate in the vertical direction. Incidentally, both the cap 16 and the head 18 are molded from plastic. The cap 16 is integrally provided with a chevron-shaped projection 20 on its inner surface, and the lower slope of the projection is formed more gently than the upper slope. On the other hand, the container opening 14 has a single-sided protrusion 2 on its outer surface.
2 are integrated. In such a configuration, if the head 18 is mounted from above the container mouth 14, the head 18 can be mounted with a small pushing force and will not come off easily. In addition, since it is sufficient to simply lower the head 18, it is easier to install and automation of the installation is facilitated compared to conventional installation using screws. Although the head 18 is attached to the cap 16 so as to be able to reciprocate vertically, it may also be movable horizontally or diagonally.
Further, a concentric hollow cylindrical part 24 extends downward from the top 23 of the cap 16, and a number of ribs 26 are formed on the cap 16 in opposition to this cylindrical part. The upper end of 14 is firmly held.

The cap 16 further includes concentric hollow cylindrical parts 28 and 30 extending vertically from the top part 23, and a suction pipe 31 is fitted to the outside of the lower cylindrical part 30. Further, on the inner circumferential wall of the lower cylindrical portion 30, a plurality of
In the embodiment, four axial grooves 32 are formed. Therefore, if a suction pipe is fitted inside the lower cylindrical part 30 instead of outside, and a foam material 33 like a sponge is placed inside the upper cylindrical part, the liquid in the container will be foamed and flowed out. Ru. In other words, the dispenser 10 can be used as a format. Further, when a highly viscous liquid is to be discharged, it is preferable to fit a small-diameter suction pipe inside the lower cylindrical portion 30 without disposing a foam material.

A pair of protrusions 34, 3 are provided on the outer surface of the upper cylindrical portion 30.
5 are formed spaced apart in the axial direction. A corresponding projection 36 is also formed at the lower end of the inner surface of the head. When the protrusions 34 and 36 engage, the head 18 is moved to the lowered position (see FIG. 1).
However, the raised position (see FIG. 2) is obtained by engaging the engaging protrusions 35 and 36.

Further, an engagement hole 40 is formed in the head top 38, which engages the upper end of the upper cylindrical portion 28 of the cap when the head 18 is in the lowered position to provide a liquid tight seal therebetween. It has a shape like that. In other words, the head top 38 forms a sealing means 41 together with the upper cylindrical portion 28 of the cap. In the embodiment, the wall thickness of the upper end side surface of the upper cylindrical portion 28 is made thinner, and the diameter of the engagement hole 40 is made smaller than that of the upper cylindrical portion 28.
Since the outer diameter of the cap 16 is made slightly smaller than the outer diameter of the cap 8, the upper end of the cap 16 is deformed and engaged with the engagement hole, thereby providing reliable liquid tightness. The sealing means is not limited to the illustrated configuration, and various types can be considered. For example, without providing an engagement hole, a hollow or solid cylindrical hanging part is provided on the head top 38, and this hanging part is engaged inwardly or outwardly with the upper end of the upper cylindrical part 28 to maintain a liquid tightness. May be secured.

The cap 16 has a beak 42 on the side of the top, and a liquid outflow path 44 that can communicate with the suction tube 31 is formed in the beak. This liquid outflow path 44 communicates with the suction pipe 31 when the head 18 is in the lowered position (see FIG. 1), and when the head 18 is in the lowered position (see FIG.
(see figure), communication is blocked by the sealing means 41. A seal cap 46 is rotatably molded integrally with the cap 16 via a hinge 47. The seal cap 46 has a seal piece 48 that fits within the liquid outlet passage 44 and closes the opening of the liquid outlet passage.
In the illustrated embodiment, the sealing piece is integrally molded from plastic with the sealing cap and is hollow to facilitate fitting. However, the configuration is not limited to this, and for example, it may be fitted outside the liquid outflow path to close the opening, or it may be shaped like a needle and fitted into the liquid outflow path.
Alternatively, instead of being integrally molded, it may be molded from rubber or the like and attached to the plastic seal cap 46.

In addition, as can be clearly seen from FIG. 3, the beak 42
A pair of ribs 50 are formed on the upper surface of the holder, and a partially cylindrical projection 51 is provided on the inner surface of each rib. Then, a protrusion 5 that can engage with the protrusion 51
2 are formed on the sides of the seal cap and 46. By rotating the seal cap 46 about the hinge 47 and engaging the protrusion 52 with the protrusion 51, the seal cap 46 is gripped onto the upper surface of the beak 42 (see FIG. 2). In other words, the protrusions 51,5
2 constitutes a gripping means 53. Therefore, the liquid can flow out without being obstructed by the seal cap and 46. Note that the seal cap 46 may be configured to be held on the lower surface of the beak portion 42. Note that the gripping means 53 is not limited to the configuration of the embodiment, and the gripping means 53 is not limited to the configuration of the embodiment.
It is sufficient to have a structure that engages with and grips the handle. For example, a partially spherical engagement hole may be formed in either the seal cap 46 or the beak 42, and a corresponding partially spherical engagement projection may be formed in the other.

Additionally, dispenser 10 includes a virgin seal 54 to prevent accidental spillage prior to first use. This virgin seal 54
As shown in FIG. 4, it has a long hole 55 into which the beak 42 of the head is loosely inserted, and is integrally and releasably made of plastic with the cap 16 via a hinge 56 (see FIG. 1). Molded. Also,
As shown in FIGS. 5 and 6, by cutting out a portion of the virgin seal 54, the tab 58 is
It is formed in the virgin seal at a distance of approximately 180° from the elongated hole 55. A lower cutting groove 60 with an approximately V-shaped cross section that extends from the lower right end of the tab 58 in a gentle arc to the hinge 56 forms the virgin seal 54 .
is formed on the inner surface of the Further, an upper cutting groove 61 of a similar shape extending horizontally from the upper right end of the tab 58 to the elongated hole 55 is formed on the inner surface of the virgin seal 54. In such a configuration, when the tab 58 is hooked with a finger and pulled toward the right end of the tab, the virgin seal 54 is broken along the cutting grooves 60 and 61. When all the lower cutting grooves 60 are cut, the virgin seal 54 is then cut along the hinge 56, and when all the upper cutting grooves 61 are cut, the virgin seal 54 is almost peeled off from the cap 16. Thereafter, by further pulling in the circumferential direction, the remaining hinges are also severed and the virgin seal 54 is peeled off from the cap 16.

The head 18 is connected to the cap 1 as follows.
6. As shown in FIG. 4, the cap 16 has an opening 64 that is slightly smaller than the width of the beak 42, and the beak is aligned with this opening and the head 18 is opened.
into the virgin seal 54 of the cap 16 from above. Then, the beak portion 42 descends and is inserted into the elongated hole while laterally expanding the opening 64. Notch 66 to be engaged with rib 50 on the upper surface of the beak
is formed in the virgin seal 54, and by engaging the rib with the notch, the head 18 is fixed in its lowered position unless the virgin seal 54 is peeled off. The presence of such a virgin seal 54 prevents inadvertent leakage of liquid before use and provides a triple seal to the dispenser 10.

〔Effect of the invention〕

As described above, according to the present invention, a cap into which a suction pipe can be attached is attached to the mouth of a container in which a liquid is stored, and a liquid outflow path that can communicate with the suction pipe is formed. A head with a beak on the side of the top is attached to the cap. When the head is located at a position where the liquid outflow path does not communicate with the suction pipe, the sealing means ensures liquid tightness between the top of the head and the upper end of the cap. Further, a rotatable seal cap for closing the opening of the liquid outlet is integrally molded on the head via a hinge.

In such a configuration, liquid tightness is achieved in the pushed-in position (inward position) of the head, where the top of the head is pressed against the upper end of the cap. Therefore, liquid tightness is independent of the gap between the head and the cap, and reliable liquid tightness is possible. Furthermore, since the opening of the liquid outflow path is closed by the seal cap, leakage of residual liquid in the liquid outflow path is also prevented.

Furthermore, if a gripping means is provided between the head and the seal cap that allows the head to grip the seal cap at a position that does not block the opening of the liquid outflow path,
The seal cap does not obstruct the flow of liquid during its flow.

Additionally, a peelable virgin seal is preferably integrally molded onto the cap via a hinge to secure the head in a position where the fluid outlet does not communicate with the suction tube. With such a configuration, the head cannot reciprocate along the hinge unless the virgin seal is peeled off, thereby preventing unintentional leakage of liquid before use. In other words, a triple seal can be applied before the start of use, and even more reliable liquid tightness can be obtained.

The above embodiments are for illustrating this invention, and are not intended to limit this invention in any way, and any modifications, modifications, etc. made within the technical scope of this invention are also included in this invention. Needless to say.
