Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cap device to be assembled to a large wide-mouth bottle mouth tube, which has an excellent hermetic seal and facilitates liquid pouring. Moreover, the amount of liquid poured out can be measured.

[Conventional technology]

A measuring cap that functions as an outer cap that measures the amount of the poured content liquid and a guide piece that facilitates the operation of pouring the content liquid into the measuring cap are provided in an upright position inside the bottle mouth. A cap device including an inner plug body to be fitted and assembled is known.

This conventional cap device, almost the entire inner plug,
Since the peripheral wall, which is the measuring function part of the measuring cap, is fitted into the bottle mouth part, the bottle body to which this cap device is assembled needs to be a wide mouth bottle body.

Further, in this conventional cap device, since the inner plug body can be molded with a soft synthetic resin, a part of the inner plug body has a packing function.

[Problems to be solved by the invention]

However, in the above-mentioned conventional technology, since the structure has a packing function in a part of the inner plug body, the structure of the inner plug body and the measuring cap is complicated by that much, and it takes time and effort for molding, There is a problem that the molding cost increases.

In addition, since the wide-mouth bottle made of synthetic resin has a large diameter at the mouth, the molding accuracy of the inner peripheral surface of the mouth is poor, the smoothness of the opening end face of the mouth is not uniform, and the deformation due to resin shrinkage after molding occurs. In addition, since it is almost always burr molding, there is an inconvenience that the roundness cannot be compensated. For this reason, the packing function exhibited by a part of the inner plug body is sufficient to seal the bottle. There was a problem that it could not be achieved and maintained.

Therefore, the present invention has been devised in order to solve the above-mentioned problems in the prior art, and enhances the mouth-sealing sealing function of a cap device having a weighing function assembled to the mouth of a wide-mouth bottle. It is a technical object to provide a simple structure, excellent sealing performance, good moldability, and low cost manufacturing.

[Means for solving problems]

Hereinafter, the configuration of the present invention will be described with reference to the drawings showing an embodiment of the present invention.

The cap device of the present invention comprises an inner plug body 5, a measuring cap 9 and a packing 15.

The inner plug 5 is made of a soft synthetic resin, and a tapered trough-shaped guide piece 8 projects from the upper end of the cylindrical wall 6 from the lower end of the cylindrical wall 6 that fits into the mouth cylinder of the wide-mouth bottle 1. It stands upright.

Further, the measuring cap 9 has a top double cylinder shape, and its peripheral wall 10 can be inserted and positioned between the cylindrical wall 6 and the guide piece 8 described above. Assembling cylinders 11 are hung in series via 12 and further assembling cylinders 11
A thread 14 is screwed around the thread 4 of the mouth tube 2 on the inner peripheral surface of the.

The packing 15 has a ring shape and is assembled to the measuring cap 9 in a state of being in contact with the lower surface of the collar piece 12 of the measuring cap 9 described above, and when the measuring cap 9 is screwed and assembled to the mouth tube. Is closely contacted with the upper end surface of the mouth tube 2.

The measuring cap 9 can store a predetermined amount of liquid in its peripheral wall 10 by removing it from the mouth tube 2 and making it upside down. Further, the inner cap 5 is tapered in a form protruding from the upper end of the tube wall 6. Since the gutter-shaped guide piece 8 is provided upright, if the bottle body 1 is tilted in a predetermined direction, the liquid in the bottle body 1 can be maintained in a constant direction by a small amount through the guide piece 8. It will be poured out, and the pouring into the measuring cap 9 becomes extremely easy.

Further, the packing 15 is fitted and assembled in the peripheral groove while being in contact with the lower surface of the collar piece 12 forming the bottom surface of the peripheral groove formed between the peripheral wall 10 and the assembling cylinder 11. There is.

In this way, since the packing 15 can be assembled to the measuring cap 9 by fitting and assembling into the circumferential groove, even if the packing 15 is simply fitted and assembled, Assembling becomes relatively stable and the assembling operation becomes easy.

[Action]

In the above configuration, the backing 15 has the measuring cap 9
Since the measuring cap 9 is brought into contact with the lower surface of the collar piece 12 and is brought into contact with the upper single surface of the mouth tube 2 by screwing the measuring cap 9 into the mouth tube 2, the hermetic seal in the bottle body 1 can be ensured. Will be achieved.

That is, since the portion where the packing 15 is located is a narrow area formed by the outer peripheral surface of the upper end portion of the peripheral wall 10, the lower surface of the flange piece 12, and the inner peripheral surface of the upper end portion of the assembly cylinder 11, the seal here is The concentrated force is applied directly through the packing 15 located between the measuring cap 9 and the mouth tube 2 to be screwed together, and this is directly achieved, which is extremely reliable.

Further, since the packing 15 is securely held between the peripheral wall 10 and the assembling cylinder 10, there is no inconvenience such as displacement.

Further, since the packing 15 achieves the sealing as described above, the inner plug body 5 or the mouth tube 2 with respect to the mouth tube 2 is
It is not required that the metering cap 9 and the inner cap 5 and the metering cap 9 mutually seal against each other, so that the structure of the inner cap 5 or the metering cap 9 is extremely simple.

In particular, since the packing 15 is a single product, its molding material can be freely selected and set to a material having a high packing effect, and thereby a higher and reliable sealing effect can be obtained.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

The bottle body 1 for containing the liquid has a locking peripheral strip 3 provided on the inner peripheral surface of the upper end portion of the mouth tube 2 and a threaded strip 4 provided on the outer peripheral surface.

The inner plug body 5 is made of a soft synthetic resin, and has a locking strip 7 around which the above-mentioned locking circumferential strip 3 is locked from below, on the outer periphery of the upper end of a cylindrical wall 6 fitted in the mouth tube 2. ing.

The guide piece 8 provided on the inner plug body 5 has, for example, a tapered gutter shape formed by obliquely cutting the tubular body, and has a height at which the tip portion projects upward from the upper end of the tubular wall 6. Since it is erected upright, the peripheral wall 10 of the measuring cap 9 is
The height of the collar 12 is such that the surrounding wall of the peripheral wall 10 can be accommodated. By installing the measuring cap 9, the top end cylindrical shape of the measuring cap 9 is formed.

As described above, a certain amount of liquid can always be poured out using the measuring cap 9, but the direction of the liquid poured out from the bottle body 1 is also accurate, and the measuring cap 9 can be attached to the mouth tube 2. In the reassembled state, the peripheral wall 10 portion containing the liquid is the inner plug 5
Since it is located inside the cylindrical wall 7, the liquid remaining in the measuring cap 9 surely returns to the inside of the bottle 1 and does not cause the inconvenience of contaminating the outer surface of the bottle 1.

The ring-shaped packing 15 is a member that is made of, for example, soft rubber and is highly elastically deformable. The ring-shaped packing 15 is deformed by the pressing cap 9 and the mouth tube 2 directly from above and below and deforms the mouth tube 2. It is designed to ensure a tight seal.

[Effect of device]

As is clear from the above description, the cap device according to the present invention directly seals the space between the measuring cap and the bottle mouth tube with a high sealing effect, so that the sealing is reliable. In addition, a high sealing effect can be obtained, a good sealing can be achieved even if the mouth tube is slightly deformed, and the amount of liquid dispensed can be accurately measured. Moreover, since the structure of the inner plug and the measuring cap can be designed without considering the sealing function, it is easy to mold and has many excellent effects. .
