Description

  When injecting contents from a refill container such as a shampoo or detergent into a container with a pump, the present invention holds the pump pulled up from the container on the mouth of the container main body to a pump and a cap at the time of refilling work. The present invention relates to a pump holder for holding a pump at the mouth of a container main body so as not to contaminate the surroundings with the attached contents or to become unsanitary due to dust or dirt adhering to a pump cylinder or the like.

In the case of shampoo, detergent, etc., when the contents in the pump container are used up, an example of use in which the same type contained in the refill container is refilled and used is widespread.
The refill container used for this kind of application uses a pouch or a simple narrow mouth bottle.When refilling, cut the pouch inlet or open the bottle cap, and then remove the pump. The refill solution is injected from the mouth of the container body.
When refilling in this way, it is necessary to lift the pump from the container body and set it aside, so that the contents attached to the pump cylinder and suction pipe adhere to hands, clothing, and the surrounding area. There is a drawback of getting dirty.
In addition, shampoos and detergents are not so much of a problem, but in the case of sterilizing liquids, there is a concern that germs may adhere to pump cylinders and suction pipes that are removed after refilling.

From such a point of view, there is a proposal of a liquid ejector that can be refilled while the pump is pulled up and held at the mouth of the container body at the time of refilling (Japanese Patent Application Laid-Open No. 2004-292034).
The content of this publicly known example is “a container with a dispenser comprising a container, a pump with a suction pipe suspended at the lower end, and a pump receiver attached to the container mouth, the pump receiver being a container A holding cylinder attached to the mouth portion and a holding cylinder are provided, and a holding rod having a suction pipe fitting portion at the tip is continuously provided at the lower end of the holding cylinder, and a flow hole is formed between the holding rods. A container with a dispenser characterized in that the container comprises a container, a pump having a suction pipe suspended at the lower end, and a pump receiver attached to the container opening. A container with a dispenser, wherein the pump receiver includes an attachment cylinder and a holding portion connected to the attachment cylinder via a linkage, and the holding portion is an externally connected to the linkage. It has a tube and a fitting tube that holds the pump, and the space between the linkages is a flow hole Dispenser with container characterized and. "Is (claim 2).

However, in the case of the above-mentioned known example, the pump receiver is attached to the container mouth, and the suction pipe on the pump side is only inserted into the holding cylinder of the receiver, so that it will come off if the pump is pulled up too much. In addition, since the pump cylinder and suction pipe are exposed when the pump is pulled up, there is a drawback that the hands are soiled and various germs adhere.
In addition, since the refill liquid flows through the holding cylinder, the amount of inflow is small, refilling takes time, and overflowing may occur if the momentum is good.

Next, as a publicly known example having the same purpose, there is one disclosed in Japanese Patent Application Laid-Open No. 2004-298804.
This known example is as follows: “When the cylinder 9 is suspended inside the container body 2, the mouth neck portion 7 is closed and the pump 3 is detachably attached to the container body. An injection window 22 in which a liquid sucking pipe 10 is suspended and the liquid in the container is ejected by the operation of the pump, the upper end of which is fixed to the mouth and neck. A large-diameter portion 23 with a clearance from the cylinder, and a locking piece 24 that is in contact with the downward surface f of the container body and prevents it from coming out and protrudes obliquely upward from the large-diameter portion, In addition, a cylindrical member 4 is provided in which a small-diameter portion 25 slidably fitted on the outer periphery of the pipe is extended downward from the large-diameter portion, and the pump is pulled up to a position where liquid can be injected from the mouth-and-neck portion. When the pump is It is an feature "that the state maintained is configured to be.

However, also in this known example, if the pump is pulled up too much, it may come off, and the liquid inflow space between the refilling liquid injection cylinder 9 and the cylindrical member 4 is small, and refilling takes time, When the pump is pulled up, the cylinder is exposed (see FIG. 3), and the hands are soiled and various germs adhere.
In addition, since the pump lifting amount is not fixed, it is not easy to use.

  An object of the present invention is to provide a pump holder that holds a pump at the time of refilling in which the above-described drawbacks are eliminated.

  In order to achieve the above object, in the invention according to claim 1, in the pump holder used for the container with a pump, an attachment portion for the pump or the pump cap is formed in the upper portion, and an injection port is formed in the intermediate portion, A pump holding stopper that engages with the lip of the container body from above is formed in the lower part, and the stopper that prevents the pump from coming off by pulling the pump more than a certain amount within the mouth part of the container body at the lower part of the pump holding stopper. It is characterized by forming a stopper.

Furthermore, in the invention described in claim 2, in the pump holder used in the pump-equipped container according to claim 1, the whole is bent in a dogleg shape, and the injection port is positioned outside the bent. It is characterized by being formed.
According to the present invention, since the injection port opens widely, refilling can be performed easily.

Furthermore, in the invention according to claim 3, in the pump holder used for the pump-equipped container according to any one of claims 1 or 2, the pump holder is integrally formed using a flexible resin, It is characterized by.
According to this invention, the manufacturing cost of the pump holder can be kept low.

[Action]
The pump holder attached to the pump or the pump cap, when the pump is pulled up from the container body for refilling by a certain amount, the stopper is engaged in the mouth of the container body, and the pump cannot be lifted further. . At this time, since the pump holding stopper engages with the mouth edge of the container body from above, the pump can be held on the mouth of the container body as it is. As a result, the refill liquid can be injected into the container body with the inlet of the refill container facing the inlet. When the injection is finished and the pump is pushed into the container body, the pump holding stopper and the holder itself are deformed by their elastic action, so that the pump can be easily incorporated into the container body again. ,

Since the pump holder according to the present invention is configured as described above, the following effects can be obtained.
1. When the pump is pulled up for refilling, the stopper will come into contact with the mouth of the container body and prevent further lifting, so the pump will not accidentally come out and the pump holding stopper will stop at the mouth of the container body. When the pump is released here, the pump holding stopper engages with the mouth edge from above. As a result, the refill liquid can be easily injected from the injection port.
2. In the unlikely event that the container body falls down during injection, the pump holder is firmly secured to the mouth by the stopper and stopper to prevent it from coming off.
3. Since the pump holder is integrally formed of an elastic resin, the stopper itself is deformed along with the deformation of the stopper, so that the pump can be smoothly inserted and removed.
4). If the holder itself is formed by the hollow forming method, the mold cost can be reduced.

  An embodiment of the above-described pump holder according to the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view showing the entire pump holder, FIG. 2 is an explanatory view of the upper half of a pump container equipped with the pump holder, FIG. 3 is an explanatory view of a state in which the pump side is pulled up from the mouth of the container body, FIG. 4 is an explanatory view showing a state in which the refill liquid is injected into the container body.

As shown in FIG. 1, the pump holder 1 is formed with a ring 2 that also serves as a packing at the upper end, the support piece 3 is suspended from the inner edge of the ring 2 at equal intervals, and the lower end of the support piece 3 is connected to the ring 5. In this structure, a pull-up prevention stopper 6 is formed at a spread angle of about 90 ° in the horizontal direction from the lower edge of the ring body 5, and a pump holding stopper 7 is projected substantially in the middle of the support piece 3. When the pump holder 1 is pushed in with a constant force, the pump holding stopper 7 is deformed by hitting the lip, allowing insertion into the mouth, and pulling it up and releasing the hand from the pump. Return to shape. Reference numeral 4 denotes an inlet opening between the support pieces 3.
In the first embodiment, the pump holding stopper 7 has a right-angled triangular shape with R on the upper side, but may have a triangular shape with an inclination or R on the upper and lower sides, or a semicircular shape. In particular, this shape may be any shape as long as it has a function as a stopper and smoothly enters and exits into the mouth when a force is applied.

As shown in FIG. 2, the pump holder 1 is attached to the pump 14 side so that the ring 2 is sandwiched between the upper edge 12 of the mouth portion 11 of the container body 10 and the pump cap 13. The cylinder 15 of the pump 14 is directed downward through the center of the pump holder 1, and a suction pipe 16 is suspended from the cylinder 15 near the bottom of the container body 10. When the pump holder 1 thus attached to the pump 14 is first inserted into the mouth 11 of the container body 10, the stopper stopper 6, the pump holding stopper 7 and the holder itself are deformed, so that the pump 14 and the pump The holder 1 can be easily pushed into the container body 10.
By driving the pump head 17, the pump 14 can suck up the liquid in the container body 10 and eject the liquid from the nozzle 18.
