Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a container. More specifically, it relates to a container such as a container for cosmetics, a container for quasi drugs or a container for pharmaceuticals.

[0002]

2. Description of the Related Art Conventionally, as a container containing a lotion, for example, there is a container in which a cap is detachably attached to an inner plug attached to an upper portion of a container body. Also,
In order to improve the aesthetics of the container, shoulder parts are attached to the shoulder of the container body. A glass bottle is usually used for the container body of the cosmetic container, but a synthetic resin such as polyethylene or polypropylene is used as the material for the shoulder parts.

[0003] In recent years, when disposing of used containers, as part of a recycling movement, consumers are required to separate resource waste by material and dispose of it. For this reason, in order to make it easier for consumers to separate and discard containers that have used up lotion, a recess is formed in the side surface of the resin shoulder part, and a tool such as a screwdriver or a coin is formed in the recess. We provide a structure to separate the shoulder parts from the glass bottle after inserting the.

However, the work of inserting a screwdriver into the recess of the shoulder part to separate the shoulder part from the glass bottle is likely to be complicated for the consumer, and there is a fear that the separate disposal is avoided by the consumer.

On the other hand, as a container for easily separating the container body and the shoulder member (cover) made of different materials, there is a container in which the container body and the shoulder cover are mounted by rotating operation (Japanese Patent Laid-Open No. 10-16979). JP-A-11-49168
(See Japanese Patent Publication). Such a container is easier to separate than a container to be separated by using the above tool, but since the cap is screwed to the container body together with the shoulder cover,
When disposing of the used container, it is necessary to perform the screw tightening release operation twice, and there is a problem that the separation work is still troublesome.

On the other hand, there is a container in which a cap is detachably fitted to a shoulder member (shoulder part), and the shoulder member is pressed and fixed by a lower end of an outer periphery of a discharging tool screwed into a mouth portion of a bottle body. (See Japanese Patent Laid-Open No. 2000-109074). However, when discarding a used container, such a container must be unscrewed from the discharge tool, and then the shoulder member must be removed by fingers or by inverting the container, so that the shoulder member is accidentally dropped on the floor. There is a fear that the separation work will be troublesome.

[0007]

The container body 1 comprises an inner stopper 3 attached to the upper end surface of the shoulder portion and a cap 4 attached to the inner stopper 3, and the inner stopper 3 is fitted to the upper end surface portion of the shoulder portion of the container body 1. And a spout 7 that is screwed into a male screw portion 6 formed on the upper portion of the lead-out barrel 2. The container body 1 is a glass bottle having a wide bottom and a slightly narrower cross section toward the top and having a non-circular cross section, for example, a substantially oval shape. The lead-out tube 2 is made of glass and is formed integrally with the container body 1. Besides the container body 1, the container body 1 is made of synthetic resin such as polyethylene or polypropylene. A pouring portion 8 is formed on the upper end of the pouring plug 7, and
In the pouring hole 9 of the pouring portion 8, the sealing plug 1 in the cap 4
0 can be inserted. The cap 4
Is composed of an outer cap 4a and an inner cap 4b mounted inside the outer cap 4a, and a sealing plug 10 for sealing the pouring hole 9 is formed in the inner cap 4b. The outer cap and the inner cap may be integrally molded.

In the present embodiment, a separating means is formed between the shoulder part 5 and the spout 7.

As the separating means, there is an inward locking piece 11 formed on the upper end of the shoulder part 5, and a lower end of the spout 7 located below the locking piece 11. It is possible to use the one composed of the outward locking piece portion 12 formed on the portion.

Further, a locking piece 13 which can be expanded in diameter (elasticity) hangs down on the locking piece portion 11 in the inward direction, and an annular projection formed on the upper end surface of the shoulder portion of the container body 1. A locking projection 15 that is fitted to 14 is formed. Further, locking projections 17 and 18 are formed to engage with the locking piece 16 hung on the outward locking piece 12 and the locking piece 13 of the inward locking piece 11, respectively. . This allows

The fitting by 8 can be released.

Therefore, in this embodiment, when the spout 7 is rotated to release the screw fitting, the spout 7 starts to rotate and the locking projection 17 presses the locking projection 18. As a result, the locking piece 13 expands (deforms) in the outward direction, and at the same time, the outward locking piece 12 lifts the inward locking piece 11. As a result, the locking projection 15 comes out of the annular projection 14. Then, the shoulder part 5 can be removed together with the spout 7 from the lead-out barrel 2 and the container body 1. Therefore, in the present embodiment, the used container can be easily separated into the container body, the shoulder parts, and the pouring plug, which are component parts of different materials. The locking protrusions 17 and 18 can be omitted if necessary.

Next, another embodiment of the present invention will be described. As shown in FIGS. 4 to 8, the container B according to the present embodiment includes a container body 21, a lead-out tube 22 formed on the upper part of the container body 21, an inner plug 23 attached to the lead-out tube 22, and the inside thereof. It has a cap 4 attached to the stopper 23. The container body 21 is a glass bottle having a wide bottom and a slightly narrower cross-section toward the top and having a non-circular cross section, for example, a substantially elliptical shape. The lead-out tube 22
Is made of glass, is formed integrally with the container body 21, and has a male screw portion 25 on the outer periphery of the lower portion and an annular projecting portion 26 on the outer periphery of the upper portion.

In the present embodiment, parts other than the container body 21 are made of synthetic resin such as polyethylene or polypropylene.

The inner plug 23 includes a shoulder part 27 and a pouring plug 2
8 and two members. The shoulder part 27 is
To improve the feel of the handle, a skirt portion 29 formed along the upper outer surface of the container body 21 and a female screw portion 30 for screwing the male screw portion 25 at the lower portion of the lead-out tube 22 are formed. It has a shoulder part base 31 which is formed.

Between the upper end surface portion of the container body 21 and the lower end surface portion of the shoulder part 27, a separating means is formed so that the container body 21 and the shoulder part 27 can be rotationally engaged and disengaged from each other. There is. At least one of the separating means is formed on the lower end surface of the shoulder part 27.
One protrusion 32 and an engagement portion 33 formed on the upper end surface of the container body 21 and into which the protrusion 32 can be inserted can be used, but preferably, as shown in FIGS. The engagement portion 33 is composed of first and second engagement protrusions 35 and 36 that sandwich the engagement recess 34, and the protrusion 3
Of the first and second engagement protrusions 35 and 36 that engage with 2, the height of at least one engagement protrusion, for example, the first engagement protrusion 35 in the horizontal direction is equal to that of the protrusion 32. It is set to a height at which the protrusion 32 can be overcome by rotating in the counterclockwise direction. As a result, in the present embodiment, when the shoulder part 27 is screwed into the lead-out tube 22 in the clockwise direction D1 with respect to the container body 21, the protrusion 32 engages with the engaging protrusion 3.
5 can be inserted into and engaged with the engagement recess 34 along the outer peripheral surface of the shoulder part 27 and the shoulder part 27
When rotated counterclockwise D2 with respect to 1, the protrusion 32
Can ride over the engaging protrusion 35 and be disengaged.

The outlet plug 28 is locked to the annular protrusion 26 at the upper portion of the lead-out tube 22 by an annular protrusion 37,
It is fitted and has a pouring portion 39 which is fitted and sealed by a U-shaped base portion 38 on the inner upper end surface portion of the lead-out tube 22 at the upper end. The pouring portion 39 is formed with a pouring hole 41 that communicates with the derivation path 40 of the derivation tube 22.

The cap 4 is composed of an outer cap 4a and an inner cap 4b mounted inside the outer cap 4a, as in the above-mentioned embodiment.
A sealing plug 44 that seals the pouring hole 41 is formed. The outer cap and the inner cap may be integrally molded.

In this embodiment, FIG. 5 and FIG.
As shown in (a) and (b), even if the shoulder part 27 is rotated in the clockwise direction D1, the protrusion 32 is not spread over the horizontal height of the inner wall surface of the second engagement protrusion 36. Can not rotate. On the other hand, when the shoulder part 27 is rotated in the counterclockwise direction D2, the protrusion 32 can ride over the horizontal height of the first engaging protrusion 35, so that the shoulder part 27 can be easily rotated. Can be made. At this time, as the shoulder part 27 is rotated and raised, the pouring plug 28 fitted in the lead-out barrel 22 can be lifted to remove the pouring plug 28 from the lead-out barrel 22 together with the shoulder part 27. Therefore, in the present embodiment, the used container can be easily separated into the container body, the shoulder parts, and the pouring plug, which are component parts of different materials. In the present invention, the protrusion 32 may be formed on the upper end surface of the container body 21, and the engagement portion 33 may be formed on the lower end surface of the shoulder part 27.

Next, a container according to still another embodiment of the present invention will be described. As shown in FIG. 9, the container C according to the present embodiment includes pump means 52 at the upper end of the pouring plug 51 instead of the pouring portion of the pouring plug in the embodiment shown in FIGS. As the pump means 52, a normal pump dispenser can be used.

Although the container body in the above embodiments is a glass bottle, the present invention is not limited to this, and a resin bottle or a metal different in kind from other parts is used. It can also be a bottle or the like.

In addition, in the container in the embodiment shown in FIGS. 1 to 3 and 9, for example, a notch is formed on the outside of the expandable locking piece so that the container cannot be deformed when the diameter is expanded and is locked. The piece can also be broken. Therefore, once separated, since the notched locking piece is damaged, the shoulder part cannot be fitted to the container body. This makes it safe to use the container after it is separated by someone and cannot be refitted after being mixed with foreign matter.

In each of the above-described embodiments, a screw having continuous threads is used, but if engagement and disengagement are possible, the structure may be such that the threads are partially omitted. Further, instead of the pouring portion of the pouring plug in the embodiment shown in FIGS. 4 to 8, it is possible to adopt a structure in which pump means is provided at the upper end like the pouring plug 51.
