Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap, and more particularly to a cap composed of a pair of cap bodies.

2. Description of the Related Art For example, a cap is attached to a container whose content is shampoo or the like. This kind of cap has a cap body having a mounting part (screw, undercut) for mounting on the container body and a nozzle part for discharging the contents, and a cap part which covers the cap body in a closed state and has a nozzle part. It is composed of a lid body having a liquid-tightly closed cap and a hinge portion for rotatably attaching the lid body to the cap body.

Conventionally, as a structure for attaching a lid to a cap body, there is a structure in which a lid is provided with a locking tongue, an insertion recess is formed in the cap body, and the locking tongue is inserted and locked in the insertion recess. (Actual number 62-115368).

However, in the cap having the above-mentioned structure, since the locking tongue piece is inserted and locked in the insertion recess, the insertion recess is necessarily disposed outside the screw forming portion forming position of the cap body. However, there is a problem in that the diameter dimension of the cap becomes large and the cap becomes large because of the provision of this mounting space. When the lid becomes large in this way,
There is also a problem in terms of design.

It is also conceivable to reduce the diameter of the cap by reducing the diameter of the container body to which the cap is attached, but it is difficult to put the contents in the container body by reducing the diameter of the cap. There is a limit to how small.

A plurality of containers provided with the above caps are packed in a packaging box and shipped, but if the caps become large in this way, the caps will collide with each other during shipping, and in the worst case, the lid body When opened, the contents leak. Further, there is a possibility that the cap may open and leak even if the product falls on the belt conveyor of the manufacturing line.

Furthermore, in a cap in which the lid and the cap body are simply integrated, if the diameter of the lid is reduced,
The cap shape is a special shape in which the container side of the cap body is large and the lid side is small. For this reason, the mold is composed of a large number of split molds, the structure is complicated, and the number of single molds to be taken is small, resulting in an expensive cap product cost. There is.

The present invention has been made in view of the above points, and an object of the present invention is to provide a cap that can reduce the shape of the lid and reduce the product cost.

Means for Solving the Problems In order to solve the above problems, in the cap according to the present invention, a first cap having an attachment portion for attachment to a container body and an opening formed in an upper surface portion is formed. A body, a base portion having a fitting portion to be fitted into the opening portion formed at an outer position and a nozzle portion for taking out contents, and a hinge integrally formed with the base portion. And a lid body rotatably attached to the base portion by the hinge portion, and in a closed state, a stopper is liquid-tightly fitted to the nozzle portion and covers the upper surface of the base portion. A second cap body in which the base portion is formed, the base portion is extended downward, and the base portion is mounted so as to be located inside the opening portion. The fitting portion formed at the outer position is the inner wall of the opening. It is characterized by being configured to be fitted into.

Action In the cap configured as described above, the cap is composed of the first and second cap bodies, and the base portion formed on the second cap body is extended downward and the base portion is Attach so that it is located inside the opening,
Further, the second cap is configured so that the fitting portion formed at the outer peripheral position of the base portion is fitted to the inner wall of the opening portion, as compared with the configuration in which the base portion is fitted outside the opening portion. The body becomes smaller. Along with this, the diameter of the lid can be reduced, and thus the diameter of the lid can be made smaller than the diameter of the container body.

Also, the cap is composed of two cap bodies,
Moreover, since the structure of each cap body is relatively simple, the structure of the mold for molding the cap body can be simplified. Therefore, the die cost can be reduced, and a large number of individual dies can be taken, so that the cap cost can be reduced.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a sectional view of a cap 1 which is a first embodiment of the present invention. The cap 1 is composed of first and second resin-molded cap bodies 2 and 3, and is attached to a container body 4 (shown by a chain double-dashed line) having a shampoo or the like as a content.

The first cap body 2 is a portion located below, and a screwing portion 5 that is screwed into a screw 4a formed outside the opening of the container body 4 is formed inside thereof. Also, the first
An opening 6 is formed in the upper surface of the cap body 2, and the second cap body 3 is fitted into the opening 6 as described later.

The second cap body 3 is composed of a base portion 7, a lid body 8 and a hinge portion 9 which are integrally molded of resin. The base portion 7 has a substantially cylindrical shape extending downward as shown in the drawing, and a fitting portion 10 that is fitted into the opening portion 6 of the first cap body 2 is formed at a predetermined position on the outside thereof. And the upper surface
A nozzle portion 11 for taking out the content filled in the container body 4 is formed on the 7a so as to project upward from the upper surface portion 7a. The lid body 8 is configured to be rotatable with respect to the base portion 7 by a hinge portion 9, and a stopper 12 and a protrusion 13 are formed at predetermined positions inside the lid body 8. In the closed state (indicated by the one-dot chain line in the figure), the lid body 8 covers the upper surface portion 7a of the base portion 7, and the closed wire 12 fits into the nozzle portion 11 in a liquid-tight manner. As a result, leakage of the contents can be prevented and the virginity of the contents can be maintained.

As described above, since the first cap body 2 and the second cap body 3 are separate bodies, they are molded by separate molds. In addition, since the second cap body 3 is fitted in the first cap body 2, the first cap body 2
The size difference between the upper part and the lower part of the mold is small, so that the number of split molds is small and the structure of the completed mold can be simplified. Also, since the structure of each cap body 2, 3 is relatively simple,
Since the number of molds to be taken can be increased and the cap bodies 2 and 3 can be manufactured with high productivity, the product cost of the cap 1 can be reduced.

In order to attach the cap 1 configured as described above to the container body 4, first, the base portion 7 of the second cap body 3 is inserted and fitted into the opening 6 of the second cap body 3, and the first and second The cap bodies 2 and 3 are integrated to form the cap 1, and subsequently, the threaded portion 5 formed on the first cap body 2 is screwed onto the screw 4a of the container body 4. With this simple operation, the cap 1 can be assembled and attached to the container body 4.

In a state where the cap 1 is attached to the container body 4, a predetermined lower portion of the base portion 7 is an opening inner wall 4b of the container body 4.
It is configured to maintain the sealing property by engaging with the liquid-tight. In addition, since the second cap body 3 is directly fitted into the opening 6 formed in the first cap body 2,
Between the first cap body 2 and the second cap body 3, a second
It is not necessary to provide a component for attaching the cap body 3 of FIG. Therefore, the outer diameter H ₁ near the opening of the container body 4
The outer diameter of the base part 7 is set to this outer diameter (indicated by the arrow in the figure).
It can be smaller than H ₁ . As a result, the diameter dimension h ₁ of the lid body 8 that covers the base portion 7 in the closed state can be made smaller than that of the conventional _one , and the lid body 8 can be prevented from colliding with each other during shipping and falling down in the manufacturing line. Can prevent leakage accidents without opening the lid.

FIG. 2 is a sectional view of the cap 14 according to the second embodiment of the present invention. The same components as those of the cap 1 shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted.

The cap 14 shown in the figure is characterized in that the first cap body 15 is provided with an extending portion 16 which is liquid-tightly engaged with the opening inner wall 4b of the container body 4 together with the screwing portion 5. As described above, by forming the extending portion 16 that engages with the opening inner wall 4b and secures the sealing property on the first cap body 15 side, the second cap body irrespective of the outer diameter H ₂ of the container body 4. 17 can be designed.

Therefore, the second cap body 17 according to the present embodiment is the first
The second cap body 3 (see FIG. 1) shown in the embodiment is downsized, and the fitting portion 19 formed on the base portion 18 does not extend downward. Instead, it is simply shaped so that it can be fitted to the side edge of the opening 20 of the first cap body 17. Further, the diameter of the opening 20 is smaller than that of the opening 6 in the first embodiment.

As a result, the outer diameter h ₂ of the lid 8 can be made smaller than the outer diameter H ₂ in the vicinity of the opening of the container body 4 (smaller than the configuration shown in the first embodiment), and the contents described above can be obtained. It is possible to prevent the leakage accident of the above and to reduce the die cost. Further, since the second cap body 15 can be formed regardless of the outer diameter H ₂ of the container body 4, the degree of freedom in design is increased, and the cap 14 excellent in design can be formed.

FIG. 3 is a sectional view of a cap 21 which is a third embodiment of the present invention. Also in the present invention, the same components as those in the first and second embodiments are designated by the same reference numerals and the description thereof will be omitted.

In the cap 21 shown in the figure, the fitting portion 22 formed on the second cap body 23 is extended to the lower side in order to improve the sealing property, and at the same time, the first cap body 24 is disposed below the opening portion 6. Forming a tubular portion 25 extending long toward the fitting portion 22
Is configured to engage with the tubular portion 25 over a long range.

Like the cap 14 shown in the second embodiment, the cap 21 configured as described above has the screw 4a of the container main body 4 which is the first screw.
Since it is screwed with the screwing portion 5 formed on the cap body 24 of
The second cap body 23 can be designed regardless of the container body 4. Therefore, the outer diameter h ₃ of the lid body 8 can be made smaller than the outer diameter H ₃ near the opening of the container body 4. Further, in the cap 14 shown in the second embodiment, since the fitting range of the first cap body 15 and the fitting portion 19 is small (see FIG. 2), if a dimensional error occurs during molding, this immediately causes the sealing property. However, in the cap 21 according to the present embodiment, since the fitting portion 22 is configured to be liquid-tightly engaged with the tubular portion 25 over a long range, a molding error occurs. Even so, the molding error is absorbed by the long engaging portion, and the sealing performance can be improved.

In each of the above-described embodiments, the shape of the first cap body is the shape illustrated in FIGS. 1 to 3, but the shape of the first cap body is not limited to this.
It goes without saying that the shape can be freely set as long as the threaded portion can be formed therein.

Effect of the Invention As described above, according to the present invention, the outer diameter of the lid can be made smaller than the outer diameter of the opening of the container body, so that the leakage accident of the contents can be prevented and the mold structure can be simplified. Therefore, the product cost can be reduced, and the flexibility in design setting can be increased.
