PLASTIC BLANK
A plastic blank includes a blank structure. The blank structure includes an elongate body portion and a head portion. One of two ends of the body portion is closed, and the head portion is connected to the other end of the body portion. The body portion has a space therein. The head portion has an opening communicating with the space. The outer periphery of the body portion is even so that a stick having product labelling can be attached onto the outer periphery of the body portion. The inner periphery of the body portion has a plurality of ribs protruded inward the space and extending along the body portion to improve the structural strength of the body portion along the length direction.
Field of the Invention
The present invention relates to a plastic blank, in particular to a plastic blank for blow molding.
Description of the Prior Art
A shown in
The outer peripheral surface 931 of the bottle 93 blow-molded by the conventional blank 9 is uneven. Therefore, the stick is attached on the protruded portions of the outer peripheral surface 931 of the bottle 93 and is not attached on the recessed portions of the outer peripheral surface 931 of the bottle 93. Accordingly, the stick cannot be firmly attached onto the bottle 93 and would be detached from the bottle 93 easily.
In addition, the annular ribs 932 can improve the structural strength along the width direction of the bottle 93 but not the length direction of the bottle 93. Therefore, when the bottle 93 is pressed, the bottle 93 would deform easily along its length direction.
SUMMARY OF THE INVENTIONOne object of the present invention is to solve the aforementioned problems and to provide a plastic blank. A bottle produced by the plastic blank has an even surface, so that a stick having product labelling can be smoothly attached onto the surface of the bottle, and the stick would not detach from the bottle easily. In addition, the ribs formed in the plastic blank improve the structural strength in longitudinal direction of the bottle, so that the bottle would not deform easily when being pressed.
To achieve the above and other objects, a plastic blank is provided and comprises a hollowed blank structure. The blank structure comprises a body portion and a head portion. The body portion is elongate shaped. One of two ends of the body portion is closed and the head portion is connected to the other end of the body portion. The body portion defines a space therein. The head portion has an opening communicating with the space. The outer periphery of the body portion is an even surface, and the inner periphery of the body portion has a plurality of ribs each protruded inward the space and extending along the body portion.
Wherein, each of the ribs is linearly extending at the inner periphery of the body portion along the length direction of the body portion, each of the ribs is equally spaced from adjacent ribs, and the ribs are annularly aligned over the body portion.
Wherein, each of the ribs is inclinedly extending at the inner periphery of the body portion with respect to the length direction of the body portion.
Wherein, the extension length of each of the ribs is equal to the length of the body portion.
Wherein, the extension length of each of the ribs is less than the length of the body portion.
Please refer to
In the first embodiment, a plastic blank is provided, as shown in
In addition, in this embodiment, each of the ribs 15 is linearly extending at the inner periphery 112 along the length direction of the body portion 11, and each of the ribs 15 is equally spaced from adjacent ribs 15, the ribs 15 are annularly aligned over the body portion 11, and the extension length of each of the ribs 15 is equal to the length of the body portion 11.
