Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container provided with a pump discharger, and aims to diversify the appearance of the container body and to reliably prevent water from entering the container.
[0002]
[Prior art]
Refillable containers such as shampoos, rinses, body soaps, etc. have been frequently used from the viewpoint of effective use of resources so that the containers themselves can be reused by refilling only the contents. The mouth portion is provided with a press-type pump discharger that enables an appropriate amount of content to be discharged. As prior literature on this point, reference is made to Utility Model Registration No. 2525993, Utility Model Registration No. 2577412, and the like.
[0003]
Such containers are assumed to be large and stationary types, but the appearance of each container is that the base cap that supports the pump discharger protrudes from the top surface of the container body and suddenly shoulders from the base cap. It has almost the same shape that falls and connects to the main body. For this reason, attempts have been made to diversify the appearance of the container by devising the structure of the container itself, but since there is concern about the intrusion of water into the container, the distinction from other containers is The company is forced to rely solely on labels and colors affixed to the body of the container.
[0004]
[Problems to be solved by the invention]
The subject of this invention exists in the place which proposes the container with a novel pump discharger which can aim at diversification of the external appearance shape of a container while preventing the penetration | invasion of the water into a container reliably.
[0005]
[Means for Solving the Problems]
The present invention relates to a container main body that houses a container filled with contents, and a nozzle head that is attached to a lid body that seals the container main body via a base cap and sucks and pressurizes the contents filled in the container. A container equipped with a pump discharger that discharges from the tip nozzle of
The lid body is provided with an opening that communicates with a mouth portion of a container filled with contents and a suction and pressurizing mechanism of a pump discharger and a groove portion that surrounds the opening,
The container is provided with a pump discharger characterized in that a base cap is fitted into the groove portion and the side walls thereof are surface-touched and the lid and the base cap are engaged with each other by undercut at the groove bottom.
[0006]
Each of the base cap and the lid is preferably a spline fitting by a groove provided on one of them and a convex part provided on the other and fitted to the groove.
[0007]
The lid has a holding portion that holds and holds the container filled with the contents on its back surface, and the tip of the holding portion and the tip of the engaging portion that engages with the container main body are located in substantially the same plane. Alternatively, it is preferable that the tip of the holding portion is shorter than the tip of the engaging portion.
[0008]
A nozzle head having a cover covering almost the entire area of the container body including its top surface is particularly advantageously adapted.
[0009]
The container filled with the contents is preferably a refill container that completely replaces the container itself, such as a thin wall blow molding container or a pouch-type container.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a view showing an embodiment of a container according to the present invention.
[0011]
In FIG. 1, reference numeral 1 denotes a container for filling the contents (hereinafter referred to as an inner container), and 2 denotes a container body (hereinafter referred to as an outer container) for housing the inner container 1.
[0012]
3 is a lid that is screw-engaged with the outer container 2 to seal it, 4 is a pump discharger, this pump discharger 4 is a cylinder 4a, a piston 4b that can be moved in the cylinder 4a, and the suctioned content It consists of a suction and pressurizing mechanism P comprising a check valve 4c and a suction pipe 4d for preventing a reverse flow of an object, and a nozzle head H connected to the piston 4b and reciprocatingly moving the piston 4b in the cylinder 4a.
[0013]
Reference numeral 5 denotes a bae skip that holds the pump discharger 4 and fixes the pump discharger 4 to the lid 3 through the pump discharger 4. The base cap 5 is engaged with a threaded portion formed inside the nozzle head H to fix the nozzle head H as shown in FIG. 2, and is connected and fixed to the base body 5a. It consists of the insertion body 5b with a taper which tapers as it goes to the front-end | tip.
[0014]
The lid 3 is provided with a holding portion 3a for holding the inner container 1 by screwing at the mouth portion 1a and a suction / pressurizing mechanism P for the pump discharger 4 in communication with the mouth portion 1a of the inner container 1. An opening 3b and a groove 3c surrounding the opening 3b are provided. The holding portion 3a of the lid 3 and the tip of the portion engaged with the outer container 2 exist in substantially the same plane as shown by the reference line L in FIG. In some cases, the height dimension until reaching each tip is substantially the same.
[0015]
The pump discharger 4 is attached to the lid 3 by inserting the insertion body 5b of the base 5 into the groove 3c, and the side surface of the groove 3c and the outer surface of the insertion body 5b contacting the side wall are It has a smooth surface and comes into contact with a surface touch so as to prevent intrusion of water or the like. At this time, the front end of the insertion body 5b and the base 5 are engaged with each other by an undercut c at the bottom of the groove, so that the base 5 holding the pump discharger 4 is not easily detached from the lid 3.
[0016]
In FIG. 1, reference numeral 6 is a convex portion provided on another side wall of the groove portion 3c, and 7 is a groove provided on the inner surface side of the insert 5b. When the base 5 is fitted into the groove 3c, as shown in FIG. 3 in an enlarged manner, the convex portion 6 fits into the groove 7 and is spline-fitted so that the base 5 rotates on the lid 3. To prevent.
[0017]
In the container according to the present invention, since the base 5 holding the pump discharger 4 is fitted into the groove 3c of the lid 3, the protrusion of the base 5 is very small, and the lid 3 and the outer container 2, Since the space region R surrounded by the inner container 1 is enlarged, by adding a device to the shape of the lid 3 and the mouth 2a of the outer container 2, it is possible to make the appearance shape different from the conventional container, It becomes possible to diversify the design of the container.
[0018]
Moreover, since the opening part 1a of the inner container 1 and the opening part 2a of the outer container 2 are located in the substantially same height, this container can attach the inner container 1 easily. It is preferable that the height of the mouth portion 1a of the inner container 1 is made higher than the height of the mouth portion 2a of the outer container 2 in order to further simplify the assembling work.
[0019]
4 (a) and 4 (b) show another embodiment of the container according to the present invention. In the figure, 8 is a cover covering almost the entire area of the outer container 2 including the top surface of the nozzle head H. FIG.
[0020]
The cover 8 can be integrated with the nozzle head H, and the cover 8 can further enhance the effect of preventing water from entering the container. In particular, in the structure in which the nozzle head H and the cover 8 are separated and held by the engaging means such as the undercut c, there is an advantage that when the inside of the cover 8 becomes dirty, it can be easily removed and washed. FIG. 5 shows the appearance of the cover 8. In the present invention, the tip nozzle area is cut out downward, but if the strength needs to be increased, It is more preferable to surround the entire circumference.
[0021]
The inner container 1 can be a refill container that completely replaces the inner container 1. In the present invention, a bag-like pouch can be used as the thin-walled blow container.
[0022]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, while the penetration | invasion of the water into a container can be prevented reliably, the external appearance shape of a container can be changed comparatively freely and identification with another container can be aimed at.
