Abstract

PROBLEM TO BE SOLVED: To deform compactly a container to increase the transportation efficiency and keeping efficiency and facilitate the disposal treatment, by deforming inward a perticularly hermetically sealable trigger bottle without the contents after use or as the contents are consumed to form a recess. SOLUTION: The preform 7 of a polyethylene terephtalate trigger bottle 1 having a circular bottom and a nearly triangular shape in the vertical section is formed by blow molding. A holder 6 with a rugged face is formed under the opening 4. The contents can be efficiently charged into the trigger bottle 1 owing to the rugged face. The contents are sprayed by a lever 8 and the volume of the trigger bottle is reduced in accordance with the decrease of the contents and a recess 9 is formed toward the vertical axial center. In this way, since the volume is reduced as the contents are consumed, disposal treatment such as transportation and keeping of the used trigger bottles 1 can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a trigger bottle whose volume is reduced with use.

[0002]

2. Description of the Related Art In a conventional trigger bottle, since the entire container is kept in a fixed shape, it is difficult to reduce the size of the entire container when contents such as used detergent, cosmetics, and medicine are not stored. Was something. For this reason, when the used trigger bottle is transported and stored for disposal, it is handled in the same bulky state as when there is a content, so work efficiency and space efficiency are poor, and waste disposal becomes difficult There was a problem.

[0003]

SUMMARY OF THE INVENTION The invention of the present application is to reduce the size of a trigger bottle, which is particularly high in sealability in a state in which contents after use are not stored, by forming a recess with use. It is an object of the present invention to provide a trigger bottle which can be deformed into any shape, has high transportation efficiency and storage efficiency, and is easy for waste disposal.

[0004]

Means for Solving the Problems The present invention relates to a trigger bottle in which a recess is formed with use.

[0005]

According to the container of the present invention, a concave portion is formed in a horizontal direction or a vertical direction by reducing the contents with use.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The trigger bottle of the present invention preferably has a recess formed in the lateral direction.

[0007] In the trigger bottle of the present invention, it is particularly preferable that a concave portion is formed toward the center of the vertical axis as shown in FIG.

[0008] The trigger bottle of the present invention is preferably formed with a concave portion in the vertical direction. The center of gravity of the trigger bottle is lowered by forming a recess in the vertical direction with use, so that the trigger bottle can be kept in a stable state even after use.

The trigger bottle of the present invention is preferably of a bellows type as shown in FIG. 5 or FIG.

[0010] The trigger bottle of the present invention is preferably cylindrical or prismatic.

[0011] The trigger bottle of the present invention preferably has a substantially conical or pyramidal shape. In the case of FIG.
Further, since the center of gravity is lowered, the state can be kept more stable.

It is particularly preferable that the trigger bottle of the present invention is formed with a holding portion provided with irregularities.
By doing so, the work of filling the contents can be easily performed, and even in use, it does not slip when held in the hand, so that it can be used in a stable state.

[0013] The trigger bottle may have a reinforced structure.

The trigger bottle may be formed by increasing the thickness of the non-recessed portion and reducing the thickness of the recessed portion of the container.

The trigger bottle of the present invention is preferably made of hard plastic. The rigid plastic makes it easier to keep the volume reduced.

As the material of the container, a commonly used material is used, such as polyethylene terephthalate, a polyolefin or a laminate including a gas barrier property containing polyolefin, a polyethylene, a laminate of polyethylene and ethylene vinyl alcohol, and the like. However, polyethylene terephthalate is particularly preferred.

In addition, transport of used trigger bottles,
For storage, the strap may be further tied, taped, or fastened with hardware so that the trigger bottle retains its condition after the volume has been reduced after use. Further, the shape may be maintained by placing the shape in a bag or a container. By doing so, the trigger bottle can be held more completely in a recessed state.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Example 1 A trigger bottle 1 of polyethylene terephthalate having a circular bottom surface in FIG. 1 and a substantially triangular cross section in the vertical direction is manufactured by pro-forming a preform 7, and having a diameter 4 at the upper end thereof. At the lower part, a holding portion 6 having irregularities is formed. Due to this unevenness, the work can be efficiently performed when filling the contents into the trigger bottle. Also, when the trigger bottle is picked up, it does not slip and can be used stably. The trigger spray unit 2 is tightly screwed to the mouth and neck 4 of the spout 5 by the cap 3. By spraying the contents of the trigger bottle 1 with the lever 8, the volume of the trigger bottle 1 is also reduced and reduced in accordance with the reduced amount of the contents, and as shown in FIG. As a result, a recess 9 is formed. The cross-sectional shapes of AA ′ before and after use are as shown in FIGS. 2 and 4, respectively. As described above, since the trigger bottle 1 of the present invention is dented and decreases in volume with use, the disposal of the used trigger bottle 1 such as transportation and storage becomes much easier than before.

Embodiment 2 The bellows type cylindrical trigger bottle 1 made of polyethylene terephthalate shown in FIG. 5 is manufactured by pro-forming a preform 7 and has an uneven portion provided at a lower portion of a diameter portion 4 at an upper end thereof. The holding part 6 is formed. Due to this unevenness, the work can be efficiently performed when filling the contents into the trigger bottle. Also, when the trigger bottle is picked up, it does not slip and can be used stably.
The trigger spray unit 2 is tightly screwed to the mouth and neck 4 of the spout 5 by the cap 3. The contents of the trigger bottle 1 are sprayed by the lever 8 and, at the same time, the volume of the trigger bottle 1 is reduced in accordance with the reduced amount of the contents, and a recess 9 is further formed as shown in FIG.
In the case of the bellows type, it is stabilized by lowering the center of gravity.
As described above, since the trigger bottle 1 of the present invention is recessed and its volume decreases with use, the disposal of the used trigger bottle 1 such as transportation and storage becomes much easier than before.

[0020]

The trigger bottle of the present invention is formed so that the volume of the trigger bottle is reduced with use, so that the space can be saved and the used trigger bottle can be collected, transported, and stored. Can be performed efficiently, and waste disposal can be facilitated. Further, in the case of the bellows type, even if the content is reduced, the center of gravity is lowered, so that it is stable. Furthermore, by providing an uneven holding portion at the top of the container, while holding the container stably,
The contents can be filled and used in a stable state. The trigger bottle of the present invention can be used not only in a state where the trigger spray unit is turned up, but also in an arbitrary position, and can be used in a state where the trigger spray unit is turned upside down and turned down. It is particularly preferable that the material of the trigger bottle is polyethylene terephthalate because its shape can be easily maintained with a reduced volume.
