Description

Title: TISSUE CULTURE CONTAINER

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a tissue culture container, and more specifically to a tissue culture 5 container that can obtain an even spread of light to raise the quality of cultured plant tissues 2. Description of the Related Art

In order to cultivate plant tissues conveniently, the plant tissues are generally placed into a tissue culture 10 container for preservation or carrying.

A conventional culture container comprises a container body for accommodation of plant tissues, and a cover mounted with an opening of the container body in such a way that a second flange of the cover is engaged with a first flange of 15 the container body, enabling the culture container to be sealed.

However, the above-mentioned culture container can be used to accommodate the plant tissues, but the sealed culture container will stop the light from passing through such that 20 the plant tissues can't grow well due to the absence of the light, causing low quality of the cultured plant tissues. Therefore, it is a need to provide an improved culture container.

SUMMARY OF THE INVENTION

25 The present invention has been accomplished in view of the above-noted circumstances. It is one objective of the present invention to provide a tissue culture container that can allow the light to pass through for cultivating high-quality plant tissues.

30 It is another objective of the present invention to provide a tissue culture container that can keep its internal space in an aseptic condition.

To achieve this objective of the present invention, the tissue culture container comprises a container body having an 10 3 fi8 8 3 2 open internal space, and a cover having a transparent plate with a concave inner surface facing the internal space, and a locating, portion engaged with the container body to seal the internal space.

5 Accordingly, the tissue culture container of the present invention can allow the light to illuminate evenly plant tissues placed in the internal space through the concave inner surface of the transparent plate for obtaining the high-quality plant tissues, and keep the internal space in an 10 aseptic condition through the engagement between the locating portion of the cover' and the container body.

Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the 15 detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed 20 description.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will become more fully understood from the detailed description given herein below and the accompanying drawings which are given by way of illustration 25 only, and thus are not limitative of the present invention, and wherein: FIG. 1 is a sectional view of a tissue culture container according to a preferred embodiment of the prevent invention; FIG. 2 is an exploded view of FIG. 1; 30 FIG. 3 is a partial enlarged view of FIG. 1; FIG. 4 is a top view of the tissue culture container according to the preferred embodiment of the present invention; FIG. 5 is a bottom view of the tissue culture container 35' according to the preferred embodiment of the present invention, and FIG. 6 is a bottom view of the cover of the tissue culture container according to the preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1 and 2, a tissue culture container in accordance with a preferred embodiment of the present invention comprises a cover 10 and a container body 30.

5 The cover 10 includes a'rectangular transparent plate 12 with a concave inner surface 14, an inclined portion 16 extending inclinedly downwards from a periphery of the transparent plate 12, a side wall 18 disposed on the outside of the inclined portion 16, and a locating portion 20 having 10 an extending section 22 extending downwards from a bottom of the side wall 18, and a hook section 24 extending outwards from the extending portion 22.

The container body 30 has an internal space 32 for accommodation of plant tissues, and a retaining portion 34 at 15 the top end thereof. When the cover 10 is assembled with the container body 30, the retaining portion 34 of the container body 30 is fitted between the extending section 22 and the hook section 24 of the locating portion 20 of the' cover 10, as shown in FIG. 3.

20 Referring to FIGS. 1, 4, and 5, since the concave inner surface 14 of the transparent plate 12 faces the internal space 32 of the container body 30, the light can be scattered evenly in the internal space 32 by the concave inner surface 14 when passing through the transparent plate 12, allowing the 25 plant tissues accommodated in the internal space 32 of the container body 30 to be exposed to the uniform scattered light.

Further, when the locating portion 20 of the cover 10 is fitted to the retaining portion 34 of the container body 30, 30 the extending section 22 and the hook section 24 of the locating portion 20 are respectively pressed against the inner and outer peripheries of the retaining portion 34 of the container body 30, preventing dust mites from getting into the internal space 32 of the container body 30, and keeping the 35 internal space 32 in an aseptic condition.

For the purpose of enhancing the engagement strength between the cover 10 and the container body 30, as shown in FIG. 6, a clipping portion 36 can be formed at each of 4 internal corners of the hook section 24 of the cover 10 for clipping the retaining portion 34 of the container body 30.

Besides, when a culture solution added in the internal space 32 of the container body 30 has evaporated, it will be 5 condensed back into a liquid again because of meeting the inner surface 14 of the plate 12, and then flow toward the inclined portion 16 along the concave inner surface 14 of the plate 12 without accumulating in the middle of the inner surface 14 of the plate 12, thereby avoiding secondary 10 pollution.

By means of the aforesaid design, the tissue culture container of the present invention can provide sufficient light to illuminate the plant tissues through the concave inner surface of the transparent plate for obtaining the high-15 quality plant tissues, and provide an aseptic space through the engagement between the locating portion of the cover and the retaining portion of the container body.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are 20 not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
